Sir: I have the lionor to transmit herewith a report on mines and quarries and petrolemn and natural-f4as wells for the year ending December 31, 1902. This report contains the statistics of the Twelfth Census of the n:ining industries of the United States. At all prior censuses the mining industries have been enumerated at the same time as the population, manufactures, and agriculture, but the date of the enumeration was changed b_y the act of Congress of March t>, VM)'l, which provides that the statistics relating to mines, mining, quarries, and minerals, shovdd be collected decennially after the completion and return of the enumeration and of the work upon the schedules relating to the products of agriculture and to manufacturing and mechanical establishments. The mining census was conducted in collaboration with the United States Geological Survey, the statistics being collected in connection with the data required for the annual report of the mineral resources of the United States. The objects of this collaboration were to avoid duplication of the tieldwork and the necessitj- of calling on the mine operators for duplicate reports; also to obtain harmonious results for the two offices. The totals for the two offices agree, with the exception of a few minerals, for which the Geological Survey includes manu- facturing processes carried on entirely distinct from the mining operations, and in some instances where that office calls for the product marketed or sold instead of that produced during the 3'ear. Mining industries are frequentlj' carried on by establishments engaged in both mining and manufacturing, and for statistical purposes it is often impossible to separate the operations. The report on manufactures for the Twelfth Census includes the statistics for all products that could be considered as the results of manufacturing processes, and such products have, as far as possil)le, l)een excluded from this report. It would add to the A^alue of these statistics if the mining and manufacturing industries were covered b}- the same enumeration and the total presented as the manufacturing and mechanical industries of the country. Under the existing law it is impos- sible to compile such a total for the same 3'ear for all branches of industiy. This report has been prepared in the division of manufactures, under the supervision of Mr. William M. Steuart, chief statistician for manufactures, assisted by Mr. Joseph D. Lewis, chief of division. I desire also to acknowledge the services of the efficient force of the Geological Survey that worked under the supervision of Dr. David T. Day, chief of the division of mining and mineral resources, and of Mr. William A. Countryman, of this Bureau, who assisted in the preparation of the textual discussion. Ver}' respectfully. Director. Hon. Victor H. Metcalf, Secretary eif Commerce and Labor. ( (xxix) MINES AND (QUARRIES. CHAPITER I. PLAN AND HCOPE OP^ INQUIRY. I. PROVISIONS OF LAW. The Fii'st Census of the I'^nited iStates, taken in 1791) by the United States marshals and their assistants, con- tained no statistics relative to manufacturing- or mining- industries. ))eing- confined to an enumeration of the inhal)itants or population of the country. The Second Census, taken in ISOO, was practically the same in scope. The first attempt to collect an}' industrial statistics was made in connection with the Third Census, under the provisions of a special amendatorj- act, passed May 1, 1810, which recjuired the ''marshals' secretaries and their assistants * * * to take * * * an account of ■•'' " " manufacturing- cstal)lishments and manu- factures." From the digest of these statistics, prepared b}' Tench Coxe under the direction of the Secretary- of the Treasury, it appears that the schedule secured in- formation concerning the cutting and dressing of marble, slate, and other stones, the quarrying- of slate, the mining of saltpeter, and the production of red and yellow ocher, but that no reference was made to min- erals from which metallic substances are derived save in the classification "lead and manufactures of lead." There was included under this classification the sub- stance known as black lead (graphite). Although the law providing for the census of 1820 contained apro- vision similar to that of the law of 1810 concerning industrial statistics, there is no evidence that statistics of mines and quarries were taken. The section con- cerning industrial statistics was omitted from the law providing- for the census of 1830. No further attempt appears to have been made to collect statistics for mines and quarries until the census of 1840, which was taken in conformity with the act of March 3, 1839. This was the first census law to con- tain a specific provision for the collection of statistics of mines. Section 13 of the law provided that "the aforesaid marshals and their assistants * * * also shall collect and return in statistical tables under proper 3022.3—04 1 heads, according to such forms as shall be fui'nished, all such information relating- to mines, agriculture, commerce, manufactures, and schools as will exhibit a full view of the pursuits, industry, education, and resources of the countr}- * * *." The Seventh. Eighth, and Ninth census(>s were taken under the act of May 23, 18.50, which authorized not onlv the enumeration of all inhabitants, but also the collection of "all the other statistical information "■'" * * specified in the instructions which shall be given by the Secretary of the Interior and in the tables annexed." Under this provision statistics of mines continued to be taken, but only in a scattering way and in comiection with other statistics until the census of 18T(), when they were given separately and with com- parative fullness. Section 18 of the act of March 3, 1879, providing- for the census of 1880, contains the following i^rovision: "And said Superintendent may employ experts and special agents to investigate in their economic relations the manufacturing, railroad, fishing, mining, and other industries of the countrj^ * * *." The form of the inc^uiries concerning mining and other productive industries was left to the discretion of the Superintend- ent of the Census and the Secretary of the Interior. The only direct reference to a mining census that is made in the act of March 1, 1889, which provided for the Eleventh Census is contained in section 17. This section provided that the only volumes to be published in connection with that census were those relating to population and social statistics, manufactures, mining, agriculture, mortality and vital statistics, valuation and pu})lic indebtedness, recorded indebtedness, and statistics relating to railroad corporations and incorpo- rated express, telegraph, and insurance companies. But among the reports which the Superintendent was "required to obtain," if directed to do so by the Secre- tary of the Interior, were those "from all corporations or establishments reporting products other than agri- cultural products." (U MINES AND QUARRIES. The act of March 3, 1899, providing for tlie Twelfth Census, was the first census law to descril.>e the scope of the mining^ census and to make a definite line of demarcation between the statistics of mines and those of manufactures. Section 8 provides "that after the completion and return of the enumeration and of the work upon the schedules relatino- to the products of agriculture and to manufacturing * * * the Di- rector of the Census is hereby authorized to collect statistics relating to * * * mines, mining, and minerals, and the production and value thereof, in- cluding gold in divisions of placer and vein, and silver mines, and the number of men employed, the aver- age daily wage, average working time, and aggregate earnings in the various branches and aforesaid divi- sions of the mining industry * * * ."' Before the reports on population, agriculture, and manufactures were completed the act of March 6, l'.H)2, ]n-ovid- ing for the establishment of a permanent CVnsus Office, became a law, and it was therefore in conformity with this law rather than that of March :-!. 1SM9, that the censvis of mines and quarries of 190::! was taken. No material change was made, however, in the pro- visions of section S, cited above. At all censuses prior to the Twelfth the statistics of mines and quai'ries, whenever taken, were collect(_>d in connection with the statistics of population, agriculture, and manufactures, and were published as a ]jart of the regular census reports. This practice is correct from both a theoretical and a practical point of view. The separation for the census of 1900 was made apparently because the work incident to the mining census might have tended to delaj" the comiDletion of the reports on the other more important subjects. It is a distinct ad- vantage, however, to have the reports on agriculture, manufactures, and mining cover the same, or pi-acticall}' the same, period, as it is thus made possible to present statistics of all branches of productive industry for the same year. Under the present law and practice the year covered by the mining census does not expire until more than two and one-half years after the close of that covered by the other industrial statistics — one being the calendar year, and the other the year ending June 1 — therefore the reports for the mining census can not ))e published until about four years after the census year covered by the statistics of manufactures and agricul- ture. The period covered by the present mining c(misus is the year ending Deceni))er 31. 1'.I02, and the condi- tions prevailing during tliat year in some brandies of mining differed materially from those that pre\'ailed during the census year ending June 1, 1900. Tiiis dif- ference is especially noticealile iti the anthracite coal industry, where tlie mining operations were practically suspended for six months, although they were in full operation during the entire year covered l)y the census of 1900. Still, in order to sliow totals for the mechan- ical, manufacturing, and mining industries, the statis- tics for these two dissimilar years nmst be combined, though the totals are a combination of statistics tluit represent a prosperous condition for manufactures and a depressed condition in one important branch of min- ing. The combination, therefore, is not indicative of the results of a year's work under either condition. The oflice was cognizant of these objections to a mining census covering the year 1W)2 and the advisability of such a census Avas carefully canvassed. After much consideration Mr. S. N. D. North, who then held the position of chief statistician for manufactures, sent the following letter of recommendation to the Director of the Census: October 11, 1902. Hon. WnxiAM K. Meeriam, I>n-rrh,r of llif CeiisUK. Deab Sir: In accordance with yonr \erbal instructions I have consulted with a number oi people, including Colonel Wright, (.'onimissioner of Labor, and 3Ir. Walcott, Director of the Geolog- ical Survey, in regard to the advisability of making a census of the mining industry as of the year 1902, in view of the fact that the coal strike in the anthracite regions has produced conditions so abnormal in that branch of the mining industry that a census taken as of the year in whic^h the strike occurred would result in data misleading and unsatisfactory. It is the judgment of all the gentlemen with whom I have consulted that the fact of the anthracite coal strike do(..s not con- stitute a good and sufficient reason for postponing the census min- ing inquiry, and in this judgment I concur. It is the opinion of i\Ir. Walcijtt that the statistics of anthracite coal mining can be taken as of the j'ear 1901 so far as quantities and values are con- cerned. It is suggested by Commissioner Wright that statistics of the anthracite coal mining industry, taken as of the year 1901, so far as quantities and values are concerned, and as of the year 1902, so far as relates to other items, will prove of great value in the immediate future in connection with the discussion of the contro- versy which has arisen between the coal operators and the coal miners of the anthracite region, and that Congress and the people of the United States ought to have the benefit of such statistics in view of important economic questions arising from the strike in question. Colonel Wright also suggests that certain questions hav- ing a direct bearing upon the existing situation in the anthracite crial region may with propriety be added to the spei'ial schedule adopted for that branch of the mining industry. I therefore recommend tliat the division of manufactures shall continue and perfect its plans for taking a mining census as of the present i-aleudar year, with a view to the commencement of field- work early in the year 190.'[.

It was also the first at which answers were required to definite questions concerning- capital, labor, luaterials, and products, but at this and the census of 1860 the statistics for mines and quarries were suljsidiary to those for manufactures, the enumeration being made by the same agencies and the. statistics included in the same tables. At the census of 1870 the statistics of mining were presented separately. The defects inci- dent to the collection of statistics for manufactures were intensified in those for mining. It was impos- sible for the UnitcKl States marshals and their assist- ants to make a complete enumeration of mines and quarries, many of which were in remote localities -avA 'd wilh ■■ quic-ksilver; " prnrlnction reported seimratcly. » Prodnetion only. the schedules used were not in ]3roper form to secure satisfactory information fi-om the mines and quarries that were repoi'ted. The following comparative table is introduced to show the character of the statistics reported for mines and quarries at prior censuses and to illustrate the ab- scTice of comparative data on any phase of the industry other than possi})ly the (juantity and value of products. The figures for 1889 in this table do not ao-ree with those in Table 4 for the reason that certain industries not considered mining have been eliminated in order to make the totals comparable; nor do they agree with those in Talile I of Chapter II because they include oidy the minerals containc^d in the body of the rep « 100, 7:54 19,8:30,010 (■I) (') (*) $25, 1.64, 924 889, .544, 435 1850 ■J 3 261 Si6, 75U 766 '34 209 812, 266 I*} 236 CI (*) 85,049,841 829, 826, 699 1 Mines, quarries, wells, and establishments. 2 Establishments. 3 Not reported. * Not reported .separately. The number of minerals for which statistics were shown at the census of 1860 would indicate that about all branches of mining followed at that time were included. It is impossible, at this late day, to deter- mine the degree of completeness obtained in the statis- tics of minerals and mining operations collected at the censuses of 1850 and 1860. It is certain, however, that there was a great deficienc}^ in the 1860 statistics of iron ore. The following statement appears in the Re- port on Manufactures for 1800, page clxxvii: "Man}' of the large iron works of the countrj' either own or farm the mineral lands and mine their own ore, which is not included in the foregoing product. The quantity thus raised in 1860 amounted to a))out 2,309,97.5 tons, which, added to the product of regular mining estab- lishments, makes the total quantity raised in 1860, 3,218,275 tons. At an average cost price of $2.10 per ton the total value would be $7,723,860." This indi- cates that more than two-thirds of the iron ore mining operations were omitted from the enumeration, but it is probable that they were included with the statistics of blast furnaces. Census of 1870. — In 187<.» the statisticsfor the mining industries were presented separately from those for manufactures. Totals were shown for the United States and for each state and territory, also for each mineral in each state by counties. The statistics were accompanied by a short explanatory text, which declared that they were entirely inade(|uato and fell far short of the total production. At 1S7(» and prior censuses the statistics, whether for mines, manufactures, or fish- eries, were all collected upon a schedule having the same form. The scope of the iiKfuiry was thus neces- sarily limited. The census of 187(» was supposed to co\eV all mines and quarries as it did manufactures, but mines and quarries where the annual production did not exceed $500 were not taken. The separation between the mining and manufacturing industries, first attempted at this census, appears to have been made with the intention of including under manufactures all 6 Includes foremen and their wages. 6 Includes 173 " female hands."

Walker, Superintendent of the Census, stated that "the statistics following are of very unequal value, for the reason that the machinery of enumeration provided by the census law of 1850 was created without consideration of cer- tain of the great mining industries of the country, * * * and can not be applied to them with any de- gree of success. It may fairly l)e taken for granted that an attempt to enumerate cotton spinning, coal min- ing, and cod fishing on one and the same schedule will always result in returns unsatisfactory' in respect to one if not two of the three industries so widely diverse in character and conditions. ''' With regard to the statistics for the pi'ecious metals Superintendent Walker says: ''The statistics of the gold and sih'cr product, as obtained ))y the census, are here published in conformity with what is understood to be the reciuirement of law; but it would be wholly unjustitiable were the figures to be put forth without a distinct and emphatic disclaimer of their validity and authority." - Criixiix of l.SSO. — The incomplete and defective char- acter of the statistics at the census (if 1S7(I and prior censuses led to the adoption of entirely different methods at the census of IssO. The sco))e of the inquirv was greatly extended, .special schedules were intrtiduced, and the conduct of the canvass and the compilation of the statistics were assigned to experts selected from the force of the United States Ueological Survey. The in- quiry not only covered the occurrence of minerals, employees and wages, and details as to the quantity and value of the different products, but extended to an analysis of the different leading minerals and the col- lection of numerous specimens. The report included 'Ninth CensuH (.f the United States, huUistn 748. ' ■ "Iljlil., \fAHf Ihi).

A directory of mines and metallurgical establishments -was also included in the report. The purpose of the inquiry, as stated in the Instructions to Special Agents, was "to elucidate as far as practicable, the character, extent, and total influence of the mining industiy. No industry has ever l)eon examined throughout an extensive region so funda- mentally and minutely as it is intended that the mineral industry of the West shall have been when this inquiry is successfully accomplished. The results -n^ill be a great addition to the data of political economy and will form a sj^stematic^accunuilation of technical facts, such as does not at present exist. " ' The subjects covered by the schedules for the pre- cious metals are as follows: JNIetallic mines. Hydraulic mines. Hydraulic ditches. Ore-dressing works. Amalgamating mills. Stamp batteries. Pan amalgamation. Roasting furnaces in amalgamating works. Alternate amalgamation and concentration of battery sands. Alternate concentration and amalgamation of battery sands. Arrastras. Smelting works in general: Preliminary operations. Smelting in shaft furnaces. Smelting in reverberatory furnaces. " Desilverization by zinc. Pattinsonizing. Improving of lead. Cupellation. In addition to the above, special schedules were pro- vided for copper, iron, and lead and zinc mines, and quicksilver production; coal mines, farmers' coal dig- gings, petroleum wells, slate and stone quarries, char- coal burning, and minor minerals. All mines were included, irrespective of the value of their products, and the ii-regular workings were enu- merated. The census, so far as it related to precious metals, was limited to mines which showed at least 200 feet of shafts and galleries or which produced 50 tons or more of remunerative ore. The enumeration was not intended to be complete, but was apparently planned with a view to obtaining- as large a number of representative facts as possible from which to draw general deductions. 'Tenth Census of the United States, Precious Metals, Vol. XIII, page 493. As a census report the work was a failure, but as a scientific and t(_'cljnical report it has considerable value. The reasons for the failure of the 1880 census of the precious metals are conciselv slated as follows: "After the Avork had been sonic time luider way, it was foiuid that both the time and the money which could be allotted to this branch were inadequate to carry it through with the perfection aimed at; that it was impos- sible to find the number of men required who were in ever}' respect fitted for it b}- education and experience; and that among owners and superintendents of mines and reduction works, while with a verv few unimpor- tant exceptions the greatest willingness was shown to grant us all the information they possessed, it was often found that thej- were themselves unable to answer the questions we asked, either through want of system in keeping records, or because they had never thought of the importance or bearing of certain facts."'' If the general canvass of all mines had been confined to the collection of a few main facts and the special technical features to representative mines, the work would have met with a larger measure of success. The failure of the census of 1880 was apparently accepted as demonstrating the impracticability of in- cluding a large number of inquiries on technical and scientific subjects in a schedule to be used for a general canvass of all mines and quarries. The establishment in 1879 of the Geological Survey, and the collection by that ofiice of technical and scientific information con- cerning- the mineral resources of the country, obviated the necessit}^ for the collection of such information by the Bureau of the Census. Therefore the scope of the census of 1890 was considerably curtailed, but followed in a general waj' the plan outlined in 1880.

The lack of uniformity in this respect added greatly to the difficulty of tabulation. "'- The statistics for 1902 are presented in this report in summarized form and in detail. The taljles show the statistics for the United States by states and by indus- tries. Each industry is also presented by states and each state In' industries. In connection with the re- ports on the difi'erent minerals, tal)les pertinent to the subject are presented. A careful study of the statistics for the difi'erent cen- suses leads to the conclusion that there are no reliable comparative data for all mines and quarries other than the quantit_y and value of products. The development of mining statistics may be con- sidered as dating from the Tenth Census. The princi- pal features of this development have been: (1) The separation of the statistics for mines and quarries from those for manufactures; (2) the adoption of special schedules designed to accentuate the i^eculiar features of the difi'erent minerals; (3) the employment of expert special agents to collect and present the data; (1) tlie collection of statistics in collaboration with the United States (.Teological Sur\-ey. M'lii'nKj (I lid iiiiiiiiifitrfiiriiKj. — Separate schedules were first pro^-ided for the mining industries at the census of 1880. Prior to that date the statistics had been collected in connectis, the same schedule ])eing applied indisciimi- nately to large manufacturing (>stalilishnients, small shops, mines, ipiarries, and fisheries. In some cases the mining industry is restricted to the digging of ore and the (piarrying of rock — that is, to ■^Eleventh Census of tlie United States, Alining Industries (excluding Precious Metals U XoX. XV, j.agp xxii. 10 MINES AND QUARRIES. the minerals as delivered f. o. b. at the mine or quarry. In others a certain amount of labor is expended in the preparation of the product for the market. All labor expended on material after it is taken from the earth maj' be regarded as employed in manufacturino-, and a strict demarcation between the two industries would so assign all such processes, but it is impossible in man}' instances to make this separation. To assist in the separation where possible and to aid in a more definite statistical presentation, all mines can be arranged in two groups: (1) Those where the product is marketed in the form in which it is extracted from the earth; (2) those where the initiatory manufacturing process is necessarilj' done at the mine or in immediate connection therewith. No attempt was made to segregate the statistics for the two branches of industry, mining and manufactur- ing, respectively, prior to the census of 1870. At that census the distinction between mining and manufactur- ing was sharpljr defined, and the statistics for mining were presented in a separate series of tables. The reasons for the distinction were given as follows: (1) Because these industries are in theory and in their jiractical relations essentially distinct. * * * The occupation of the miner is not so much unlike that of the artisan, yet writers on political economy have been quite generally disposed to hold that if the occupations of mining and fishing are to be assigned to any one of the three grand divisions of industry which have been in- dicated, it should be to agriculture, as dealing in the spontaneous products of the earth and the sea, and also as furnishing material in the earliest forms for subsequent processes of industry. (2) For convenience of reference and citation. The statistics of mining * * * occupy so little space comparatively as not to be easily found upon occasion in voluminous ta))les of marmfactures. (3j Because the statistics of mining * * * with the present modes of collection are distressingly inadeijuate to the known facts of the case, and their addition to the tables of manufacturing industry amounts to a positive disparagement of the latter. The statistics of manufactures have their own faults, as is elsewhere frankly acknowledged, under the present census system of the United States, but they are infoniparabl>' more complete and accurate than anj- statistics of mining * * * to be olrtained l)y existing machinery. To merge them with matter ."o defective is, in a degree, to subject them to the same discredit. A separation, therefore, is on all accounts desirable.' The separation at the census of 1870 was ettected in some cases bj' means of correspondence with the mine operators, so far as they were disposed to afford the information, and in other <'ases b}' estimates prepared accoi'ding to approved formulas at the 15ureau of the Census. The theoretical division between mining and manufactures thus applied is not wholly jaractical. Companies, firms, and individuals that operate both a mine and a i-eduction works, or that break, wash, screen, or roast the ore, almost iiivariabl}- consider preparation for the market a part of the mining opera- tions, and so report, insisting that the statistics can not be sepai'uted, since the employees were frequently en- gaged intcrchangeahly on both liraiichcs of the work 'Ninth Census of the [Irjifcd States, Industry and Wealth, Jiage 383. and no separate accounts wore kept either of the wages or of other expenses. At the census of 1880 the statistics related not only to mining, Init included such technical data as to the various processes by which the metals are reduced from the ores as would serve to show the actual condition of the industry,' and therefore embraced manufacturing proces.ses, such as the smelting of ores and the refining of petroleum. A more practical separation was attempted in 1890, but the statistics for that census also covered a number of maiuifacturing processes that are incident to the production of metal. At the census of 1902 the manipulation of the ore after it leaves the mine, if so interwoven with the business of mining as to be insep- arable, has been considered a part of the. mining indus- try. All other processes have been eliminated. The combination of mining and manufacturing by the use of the same capital, the same wage-earners, etc., has been accentuated by the consolidation of industrial enterprises, carried to a high state of perfection during the past decade. If the statistics for mining and man- ufacturing were to be taken together it would be easy to tincl a common term for this union and compara- tively simple to show the aggregate iigures, but such work would not suppl}^ the demand for separate statis- tics for these important industries. Where the milling, separating, washing, burning, calcining, or other proc- esses of reduction or manufacturing were carried out at the mine or quariy, the census of mines and quarries includes, as a rule, the employees, wages, miscellaneous expenses, and supplies and materials involved in the work of the entire establishment. At the census of 1902 the instructions to special agents on this subject were as follows: There are several branches of mining in which the mineral products do not reach the market in the crude condition, but are subjected to certain proces-ses at the mine or (juarry before ))eing regarded as niarketal)le commodities. These may be processes of milling, separating, washing, burning, calcining, or other forms of manufacture. In some industries tlie.se jiroces.ses are performed entirely at the mine or quarry, and in such cases the special agents are instructed that the census schedule should include the statistics of enqiloyees and wages, njiscellaneous ex]ienses,and supplies and materials involved in the entire work of mining the crude material and jireparing the same for market. Fi.r example, the following branches of mining and quarrying are of this character; Emery and corundum mines, where finished emery wheels are frequently manufactured; mica mines, sheet and crushed mica being the finished product; graphite mines, where tbe crude graphite is refined; grindstone and millstone quarries, wdiere grindstones and millstones are the finished products; mines or quarries of kaolin flint, ocher, barytes, mangane.se, chalk, talc, mica, umlier, sienna, and other iron-oxide colors, where the crude mineral is ground or other- wise prepared; marble, granite, and other stone (juarries, where the stone is cut and dres.sed and nioinunents and tombstones are manufactured; slate quarries, where rooting slate, slate black- boards, school slates, and sanitary iihnnbing slate slabs are manu- factured.

The foliated variety of talc is usuallj^ ground into talcum powder and the fibrous variety into material for paper filling. All these processes are accomplished at or near the mine. The limitation of the census inquiry to the operations at the mine or quarr}' has resulted in the exclusion of a considerable portion of the values generally assigned to the mineral products of the country. These difl'er- ences are full}^ explained in the special reports for each mineral. A comparison of the quantity of the ores as rejDorted to the Bureau of the Census for the j-ear 1902, with the quantity of the metal obtained from the same class of ore during the same period, but possibly mined, at least in part, during the preceding year, illustrates the disparity in the quantities. It is possible to make 14 MINES AND QUARRIES. this comparison for a few minerals, and the totals are given in the following statement: MINERAL. Metal obtained, or manufactured product.

As already stated, the special schedules were introduced and carried to excess at the census of 1880, which was taken under the supervision of Gen. Francis A. Walker, who had already emphasized the necessity of such a schedule in presenting the statistics for the census of 1870. There were 44 special schedules, a separate schedule being provided not merely for each of the different minerals, except those tabulated as "minor minerals," but for the different conditions under which the same mineral was mined, and different sections of the country were assigned to different expert agents, and they in turn were permitted to use different forms of schedules for the same mineral as mined in their respective districts. The use of special schedules was continued at the census of 1890, but the number of separate schedules was reduced to 23 — 1 general and 22 special. The special schedules were used to develop features pecul- iar to iron ore, gold and silver mines and reduction works, transportation of gold and silver oi-e and bullion, copper mines, lead mines, zinc mines, (juicksiiver mines and reduction works, manganese ore, precious stones, coal mines, distribution of coal for consumption, erude petroleum, natural gas, stone quarries, mineral ^vaters, copper smelters and rehners, lead smtdtcM's and rehners, lead refiners, and zinc reduction works. The object of tlie sjiecial sch<^dule is to develop in detail the teehtii(|iie of an industry and to obtain from each establishment a schedule carefully filled (Mit, the completion of which requii'cs kiK)wledg(i aiilacers, are the following: Antimony, asbestos, asphaltum, baux- ite, borax, chrome ore, cobalt, feldspar, fibrous talc, flint, fluor- spar, fuller's earth, garnet, graphite, infusorial earth and tripoli, magnesites, marls, molybdenum, monazite, oilstones, platinmu, precious stones, pyrite, crystalline (juartz, quicksilver, rutile, sul- phur, tungsten, uranium, and vanadium. Special schedule No. 8, for coal mines, both anthracite and bitu- minous, and anthracite coal washeries. Special schedule No. 9, for petroleum and natural-gas wells. Special schedule No. 10, for gold and silver and argentiferous and auriferous lead and copper mines. Special schedule No. 11, for reductiou works of the precious metals (other than smelters and refineries). Special schedule No. (3a, a supplemental schedule for adminis- trative and general offices. This schedule is intended for corpora- tions, firms, or individuals operating more than one mine, quarry, or reduction works, with a central office for all of them. Upon this schedule should be reported the employees of such central office, with their salaries or wages, and all other employees whose work is not confined to one particular mine, quarry, or reduction works, such as general superintendents, machinists, surveyors, etc. All general expenses are also to be reported on this schedule and the data relating to capital stock, bonds, dividends, and as- sessments of incorporated companies. No data reported on this schedule should appear on the separate reports for the individual mines, quarries, or reduction works. Separate schedules are sup- plied for these individual plants. Special schedule No. 6b, a supplemental schedule for bluestone, granite, limestone, marble, sandstone, slate, and trap rock quar- ries, upon which a full description of the quarrying and stone- dressing machines in use should be given. This schedule is to be filled out in addition to and supplementary to special schedule No. 6 for all stone quarries. The special schedules of the Geological Survey were in the form of small cards and were provided for the following minerals: Brick and tile. Slate. Marble. Trap rock. Granite. Sandstone. Bluestone. Limestone. Sulphuric acid. Barytes. Mineral paints. Jlica. Salt. Phosphate rock. Gypsum. Emery and corundum. Millstones. Grindstones. Soapstone and talc. Bituminous coal. Anthracite coal. Coke. Coke, by-product plants. Pottery. Clay mined. Mineral waters. Cement. Deep mines (precious metals). Reduction «'orks at mines. Placer and surface mines (pre- cious metals) . Local or custom mills or smelt- ing works (precious metals). Natural gas. Crude petroleum. Iron ore. Manganese ore. Gas, tar, and ammonia. Precious stones. Minor minerals (a general sched- ule for the production of all other minerals not included in the foregoing list). The combination of the data contained on the Census and Geological Survey schedules makes possible the presentation of complete census statistics iov the general features of the industries and also of technical infor- mation concerning each mineral. It is believed that this arrangement has resulted in the most complete and harmonious census of mines and cpiarries ever taken. It has made possible a sei^aration of the purel}' scien- tilic and technical inquiries from the statistical. At the same time, full information on each phase of the subject has been secured thr(.iugh the medium of the same agents. E,Ki>ei't upacial agents. — At the censuses of 1850 to 18*70, inclusive, the mining census was made by the United States marshals, and was incident to the enu- nteration of population and the collection of the statis- tics of agriculture and manufactures. The principal dut^' of the assistant marshals was the enumeration of population. The other three inquiries — agriculture, manufactures, and mining — were regarded as of much less importance, and it is probaVjle that their importance was rated in the order named. The tirst provision of law authorizing the employment of expert special agents is contained in section IS of the act of March 3, 1879, providing for the census of 1880. This provision was reenacted in the laws providing for the Eleventh and Twelfth censuses and in the act of March 6, 1902, under which the cens if that year was taken. Persons engaged in an industrj^, or intimately associ- ated with it through financial identification or through long experience in the compilation of statistical infor- mation concerning it, are in a position to select the data of greatest value and to pass upon the practica- bilit^' of the schedule to be used in collecting these data. The principal advantage to statistical work from the emplo3'ment of such persons is in the drafting of the schedules and analysis of the results. After the form of the schedule is determined and the inc^uiries thoroughlj^ understood, the collection of the returns requires but slight, if any, technical knowledge. At the census of 1880 an attempt was made to emplo}' experts to make the canvass,^ but it was impossible to obtain a sufficient number of agents who had either a theoretical or prac- tical knowledge of mining to do the work. At the cen- sus of 1890 experts and others were employed, the ex- pert agents, as a rule, having supervision of the canvass for certain sections of the country or for certain min- erals, irrespective of the location of the mines. In 1902 the schedules followed the general form used in collect- ing the statistics of manufacturing and mechanical in- dustries. This was necessarjr in order that the totals for maiuifucturing and mining might be combined and the aggregate for all such industries presented. More- over, as the technical schedules used bj' the Geolog- ical Survey were adopted by the Bureau of the Cen- ' Tenth Census, Precious Metals, Vol. XIII, page xi. 16 MINES AND QUARRIES. sus, there wa.s no necessity for the emplo^ynient of ex- perts hy the Bureau in the preparation of any of the returns. The canvass was made l.)y the regular force of the Bureau, assisted by the office and field force of the Geoloo'ical Survey. ( 'iillalitirdtiim initJi the Zhiited Sfatcn ijcohx/ical iSur- i-'ey- — The United States Geological Survey was organ- ized under the act of March 8, ISTIJ, which estal)lish(>d the office and, among other duties, provided that it should examine " the geological structure, mineral resources and products of the national domain." An act of Congress of August 7, 1883, provides that an amount not to exceed $1(),0U0 may be annually applied by the Director of the Surv(^y, under the direction of the Secretary of the Interior, to the procuring of statis- tics in relation to mines and mining other than gold and silver and to making chemical analj'ses of iron, coal, and oil. The first annual report of the Survey, which was transmitted to the Secretary of th(> Interior on No\'eni- ber 1, 1880, covered the fiscal year ending June oO, 1880. Since then reports have been made annually, covei'ing the calendar year. In organizing the census of 1880, Gen. Francis A. Walker made arrangements with the Geological Survey to collect the statistics of ujines and (juarries. ' Similar arrangements were made at the census of 18!t(). The Geological Survey collects annually statistics of the C[uantity and \'alue of production of the different minerals, in connection with its examination of the geological structure, mineral resources, and products of the national domain, and is necessarily in constant communication with mining companies, thus establish- ing an intimate relationship. Collaboration between the Survey and the Bureau of the Census in taking the decennial census of mines and quarries is, therefore, ideally correct, but the actual practice at earlier cen- suses of turning over to thi' employees of the Survey the entire work of collecting and compiling the census statistics resulted in a statistical pi'esentation which was out of harmony with the presentation made in all other census imlustrial statistics. In other words, the raining census of 1880 was conducted on lines some- W'hat similar to those followed hy tlie Survey in its annual reports, designed to show for tlie most part the quantity and value of the ditferent minerals, their occurrence, an analysis of ores, and the possibility of development of the miniu'al resources of the countrv. ' In 1879 Prof. Riilph Pumpelly, head of the Division of Mines anil (:) producers of oil in 39.301 oil wells in Pennsyhania, also similar combined reports for 2,lii3 producers and 8,443 wells in New York, 9,1397 producers and 42,l:(i9 wells in Ohio, 4,435 producers and 12,9.51 wells in West Virginia. There were in all 7 schedules received from the company, which con- tained the statistics for 28,925 producers and 112,794 wells. In addition to the reports of the Standard Oil Company, there were 604 schedules received from 597 producers covering the operations of 5,s77 wells. The 7 schedules from the Standard Oil Conqiany covered 98 per cent of the producers and 95 per cent of the wells reported for the United States. Similar reports were made by the company for its production of natural gas, 4 schedules being received for 19 producers and l,70l wells in Pennsylvania, New York, Ohio, and AVest Vir- ginia, the producers forming 1 \)ov cent and the wells 10.8 per cent of the total for the United States. Under these conditions it was impossible to localize the statis- tics for petrdlcuMi and natural gas l)y counties or to PLAN AND SCOPE OK IXOl'lHY- 21 check or verify the estimates of the munher of em- ployees, wages, expenses, etc. The schedules were carefully prepared and evidently cover the entire pro- duction of all the wells. The conditions under which the statistics have been compiled are in some respects similar to those prevailing)' in the minino- of lead, zinc, mica, and nionazite. in that the production is sold to one or more large establishments that put it on the market and thus in a measure control the output. Since the recent discoveries of rich plac(n- deposits have given prominence to the gold fields of Alaska, efforts have been made by the Government to obtain statistics 1\v direct connuunication with the numerous owners of those mines. Mr. Charles G. Yale, special agent of the Bureau of the Mint, reported the follow- ing for the calendar year 1,S!>9: The population of these eaiiips is more or less nomadic, moving from place to place aa strikes in new creeks are announced. The season of mail communication among the camps along the Yukon river and creeks is very short, and when the spring " clean ups" ha\'e been made or the summer diggings begin to freeze the men come "outside" for the winter or go to larger camps. For these reasons it is almost impossible to obtain the desired statistical information as to the output of gold by correspondence Avith the individual miners.' Dr. Cabell Whitehead, formerly assay er of the Mint, reported as follows from Nome, under date of Septem- ber 5, 1900: Many men are prospecting throughout the entire country and we can only tell what they produce when they come in, as they are very secretive in all matters concerning their productions.'^ The same was the experience of the agent of the De- partment of Labor, who investigated on the spot the conditions of Alaska gold mining. The difficulties in obtaining statistics of the placer mines in Alaska may be judged from the number of claims recorded, which in the Nome district alone had, up to .Tanuar}' 10, 1900, reached 1:,.500."^ This number is largely in excess of the total number of producing properties embraced in the present census of gold and silver mines for all states and territories. Important as it maj' be to ascer- tain the exact conditions under which an individual miner can nowadaj's produce gold without any capital, practically with his own hands, it was thought that this could be most successfully done in connection with the general census of population and occupations, whereas it could not be accomplished without an extraordinary expenditure of time and money as a part of the census confined to mines and mining. The quantity and value of the output of the Alaska gold mines are reproduced in this report from the rei3(jrt of the Director of the Mint, whose estimates are based upon the returns from the mints, assay offices, and from private refineries. Porto Rico was the only insular possession in which the mineral resources were deemed of sufficient impor- 1 Keport of the Director oi the Mint upon the Production of the Precious Metals during the calendar year 1899, page .51. 2 Ibid., 1900, page 56. •'P)Ulletinof the Department oi Lalior, 1900, "The Yukon and >;ome Gold Kegioii."," ]iage SOI. tance to attempt an enumeration. While it is known that a variety of minerals exist in the island, very few, if an^', mines and quari'ies were operated as a I'egular business during the year 1902. The work was done at odd times and only sufficient material extracted to satisfy the local demand. It was difficult to locate the pi'operties that had been worked, and jjractically im- possible to obtain any information concerning the num- l>er of people employed or the quantity and value of the product. Under these conditions the statistics for the island are not comparable with those compiled for continental United States, and no reference is made to them in the general tables. The report on the mineral industries of Porto Rico consists principally of a com- pilation of historical data, a statement of the mining laws, and a list of the niineral deposits, with such in- formation as could be obtained concerning the quantity and value of the products. The omission of the small producers and the impossi- bility of obtaining individual reports from certain other producers, the data being included in a combined sched- ule, are the principal sources of error in the canvass. Another source of error is inherent in the preparation of the reports. A comparati\-ely small proportion of the I'eports were prepared from data obtained from account books; but those which were prepared from such accounts were, as a rule, for the important opera- tors and represented a large propoi'tion of the produc- tion. The data in many of the schedules are estimates based on the recollection of the person answering the inquiries. This is particularly true of the answers to such inquiries as "The average number of wage-earners employed during each month" and "The average num- ber of wage-earners at specified dail}^ rates of pa}'." Fevf establishments keep books from which answers to inquiries of this character, covering a period of twelve months, could be readily obtained. If the information was obtained from the account books, it required an examination of a number of books and a large number of entries. The principal anthracite coal companies gave the office permission to examine their account books and compile the totals I'equired for an answer to each inquiry. Two clerks were detailed to New York, N. Y., and Scranton, Pa., for this work. The method of keeping the pay rolls of the anthracite coal companies, from which was obtained the average lumiber of persons employed by them during the year and the amount of wages paid, differs but slightly with the different companies. The original pay rolls are in sheet form, but by most companies are copied into books, these books being retained for office reference and the originals placed in vaults at the general offices of the companies or in storage. The census data were ob- tained from the office copies. The pay rolls are made out semimonthly. The names of the employees are written twice each month by some of the companies while others arrange their books so that both the first and last halves of each month are carried on the same 22 MINES AND QUARRIES. set of sheets. The o-reatei' numlicr of the companies keep their wage accounts "bj' collieries," having for each colliery a separate book in which are shown all the operations of that collierj' during the 3'ear. Other com- panies keep these accounts "by months," having for each month a separate book in which are shown the operations of all their collieries for that one month. Usuall}' the classes of employees were listed on the pay rolls in nearh' the same order as they are shown in the census schedide, the list being headed by fore- men, followed by clerks and the various classes as indicated; usually the employees above ground and those below ground are listed separately and designated as "outside" and "inside," respectively. Few, if any, of the companies distinguish on their pay rolls between bovs under 16 years of age and employees over that age, and the records of none of the companies show the num- ber of boj's under 16 j'ears of age in their employ. The average number of wage-earners emploj^ed during the year by these companies was obtained in all cases by first averaging each semimonthlj' sheet of the pay roll separately, adding together these sheet averages to obtain the average for the month, and finallj^ dividing the sum of the monthly averages by 12 to show the average number employed during the year. The a\'cr- aging of the number of wage-earners by sheets was accomplished by different methods. In some cases the number of men employed and the hours of labor were so uniform throughout the month that the number of names shown on the roll was used as the monthly aver- age. As the rolls were usually headed by foremen, clerks, etc., the average iuiml)ers in these classes were easily obtained, and the deduction of these averages from the sheet average would show the average nundjer of other emjiloyees; but in many cases where condi- tions were not uniform throughout the month, the sheet average was obtained by multiplying the number of employees on each sheet bv the number of daj-s in oper- ation and dividing the product by the number of working days in the month, usuall}' 25, 20, or 2T days. The sum of the sheet averages gave practically, but not exactly, the average for the montli. To have obtained an exact average would have necessitated the addition of the total number of hours worked by each man during the month, the division of this aggregate by the nunibei'of hours fixed upon as constituting a da3''s labor, and the division of tne quotient thus obtained by the number of working daj's in the month. From such monthly a\'er- ages an exact yearly average could be olttained. As no company keeps a record of the aggregate num- ber of hours of labor performed each month, the length of time which would have been required to obtain the averages liy this method would have caused too great a delay in the publication of the report. The two methods first mentioned gave sivfficientl}^ accurate aver- ages for the months in which regular forces were cm- plo^'cd throughout. It was found necessary, howi'\'(>r. to adopt the latter method to obtain the average for those months during the strike when the number of employees was constantly varying. While there were comparatively few operators for whom the preparation of the Census reports was at- tended with so many difficulties, still it is evident that the data furnished in reply to the majority of the inquiries were not o))tained from the account Ijooks. It is proliable that the percentage of error due to the fact that the answers are based on memory or rough memoranda, and not on actual records — a condition incident to all census work — is greater in the mining census than in any other branch of the industrial census. IV. OFFICE AND FIELD WORK. The most important feature of the preliminaiy work of the mining census was the preparation of the sched- ules and instructions.' This work was started in No- vember, 1902, and the last installment of the schedules was received from the Government Printing Office about the last of January, 1903. In the meantime the mailing of the schedules to the mine operators had been in progress and was completed shortly after the 1st of February, lyO;! The mailing of the schedules and the general super\'ision of the fieldwork was under the direction of the Geological Survey. The theory of the work was that the schedules, instructions, and all cir- culars necessary for the canvass should be prepared at the Bureau of the Census and placed at the disposal of the Geological Survey for transmission to the field force. As the schedules were received, either hy mail direct from the operators or from the special agents, they were inunediately turned over to the Bureau of the Census for examination, all defective schedules being returned to the Survey for correction. The Sur- vey schedule accompanied the Census schedule, and the quantity and \-alue of the products reported on both were made to agree ))efore they were separated. The Survey schedule was frequently filled and returned through the mail without the Census report, which was neglected until the field agent called. This neglect and the necessity for returning a large proportion of the Census schedules for correction resulted in the separa- tion of the schedules in such a large number of cases that a general comparison of the final tabulations was necessary to insure an agreement between the two offices. The schedules for bituminous coal, clay, stone, gyp- sum, cement, and fullers earth were the only ones mailed directly to the mines from the Washington office of the Survey. All of the other schedules were sent in bulk to the offices of the field assistants of the Sur- vey and mailed from there to the operators. About ' For coiiy of Kchedules see Appendix A, ami for instructions see A piicndix J>. PLAN AND SCOPE OF INQUIRY. 23 three weeks were allowed for the return of the sched- ules by mail. The entire United States was then di- vided into districts, and the actual canvass was started on or aliout January 15, 1903, hut at this time of the year some sections of the country are inaccessible, and it was impossible to employ the maxinumi field force until May, ly03, when there were 113 agents and clerks at work in the field or in the offices of the supervisory agents in different sections of the country. 'J'his luim- ber does not include the agents and clerks on the rolls of the Geological Surve_y who were engaged in collect- ing reports or other work incident to the canvass. The schedules were therefore returned b^^ the mining com- pany to the local office of the field assistant, given a preliminary examination there, then forwarded to the Geological Survey, where they were again examined before l)eing sent to the Bureau of the Census. The final examination was made -at the office of the Bureau, and letters criticising the schedules or calling for addi- tional information were forwarded to the Geological Survey, and from there sent to the field assistant, who transmitted them to the mine operators by mail or through a personal visit of a field agent, or obtained the information personall}', and again returned the sched- ules to the Geological Survej^ for transmittal to the Bureau. The practice of dividing the country into dis- tricts and placing .the work in each district under the sujDervision of a local official is the most efficient waj^ to conduct a canvass, but it is evident that these methods when followed in the mining census must lead to a du- plication of work and more or less confusion, especially when schedules are being received not only from field agents who visit the mines, but also from the operators themselves. The fieldwork of a mining census is necessarily based on lists giving the names and addresses of mines and quarries. The preparation of a complete list is there- fore a very important part of the office work. The lists used for the census of 1902 were prepared in the division of mining and mineral resources of the United States Geological Survej^ and are the outgrowth of the annual reports of that division on the mineral products of the country. The annual returns secured from the mines and quarries for these reports are of assistance in revising the lists at regular intervals. The names and location of new developments are obtained from technical journals and periodicals. All publications of this character are examined and notices of new mining enterprises are clipped. New producers are corre- sponded with to ascertain the full name, address, loca- tion of mine, and character of mineral. Confidential copies of the completed lists are sent at regular inter- vals to representative producers in different sections of the country for revision and the addition of new names. One of the principal advantages of the collaboration between the Geological Surve}' and the Bureau of the Census was the utilization of this list. The special agents wei'e instructed to supplement the official lists by careful inquiries in each locality visited, and to ol)tain reports from all mines that were in opera- tion during any portion of the year. Two classes were excepted from these instructions; one was tlie small placer gold mine operators and the other the irregular bituminous coal minors. It is impossible to locate the small placer miners. Moreover, the onlv statistical information that could be obtained would bo the quan- tity and value of tlieir product, which can be estimated or secured from other sources equally reliable. There- fore no effort was made to secure reports from mines of this class unless the agent was in the vicinity in connection with other work and the preparation of the reports for the small mine would cause no delay. The reports for the irregular bituminous coal producers were obtained by correspondence. Next to the schedule itself, the instructions for its uniform application are of the greatest importance. Such instructions were prepared and distributed to the special agents before they entered on dutj'. These in- structions wore of a general and special character; they defined the agents' duties and described the practices to be followed in securing schedules. They were used in connection with the instructions printed on each sched- ule, and were followed in the preparation of all reports. The office work on the mining census was in progress from November, 1902, to July, 1901. During the greater part of this time comparativel}' fewclerks were employed. The greatest number, 91, was reached on October 25, 1903, when the tabulation was at its height. The cost of the office woi'k paid for by the Bureau of the Census was $77,853.17, and of the fieldwork $98,019.78, thus making the total cost of the mining census, exclusive of the final revision of the manuscript and printing and binding, $175,872.95. The schedules for the annual report of the Geological Survej' were secured in connection with those for the Bureau of the Census, and the expenditure co\ers the collection of schedules for the reports of both offices. In some in- dustries omitted from the mining census, but included in the annual reports of the Survey, such as the manufac- ture of gas, brick, pottery, etc., schedules were collected by the Census agents and turned over to the Survey. On the other hand, considerable Census work was done by the regular employees of the Geological Survej' and at the expense of that office. After the completion of the fieldwork several of the expert special agents employed b.y the United States Geological Survey in the preparation of the annual reports on Mineral Resources of the United States were retained bj the Bureau of the Census to prepare the historical and descriptive text which accompanies the 24 MINES AND QUARRIES. statistics for the principal minerals. Thiese special agents and the minerals assigned to each are as follows: Dr. David T. Dav Dr. Joseph Struthers . Dr. Joseph Hyde Pratt . .... Mr. George F. Kunz . . Mr. John Birkinbine . Mr. E. W.

As previously explained, the schedules were mailed to all mines and quarries. There were received in all 38,151 schedules. Of this number 2s,,5(i9 were for productive and 7,193 for unproductive and idle proper- ties. In addition there were 2,389 schedules for mines and quarries that were abandoned, and therefore omit- ted from the tabulation. While comparatively few complete schedules were received through tlie mail for active properties, the mailing of tlie ])lanks was of great assistance to the lieldwork in dis[)osiiig of the names of idle and abandoned mines and uA'oiding tlie necessity of visits by agents. The tieldwork was in progress from about January 16, 1903, to February 1, 1904. The total cost of the fieldwork, as paid for by the Bureau of the Census, was $98,019.78, which in- cluded $13,061.10 paid to supervising agents and then- assistants who did no traveling. There were in all 122 different individuals, agents, and clerks engaged in the field, but of this number 39 were in a supervising capacity or employed in the offices of supervising agents 'and did no traveling. There were 83 persons engaged in the collection of schedules, the maximum number, 72, being at work in May, 1903. As the special agents collected schedules from all mines and quarries in the localities visited, irrespective of the character of the mineral, the cost of the field- work for a specific mineral can not be computed with exactness, but the average cost per schedule for the active properties, both productive and unproductive, was about $3. Using this average, the following state- ment shows the approximate cost of the fieldwork for the principal minerals: Cost of fieldwork. 898,019.78 Bituminous coal . Anthracite coal.. Iron.

The statistics are presented in 52 classifications, each comprising the total for a distinct mineral or group of minerals. In some cases minerals or ores yielding two or more products were obtained from the same mine or quarry, and it was impracticable to separate the emplo3'ecs, wages, and expenses incident to the production of each. For instance, if the ore from a mine yielded both silver and copper, the latter being of the greater A'alue, the report was assigned to cop- per, and all the emplo\'ees, wages, and expenses were included in the totals for that mineral. If the chief product of a quarry was sandstone the report was clas- sified as "sandstones and quartzites," though soQie of the product may have been manufactured into and sold as grindstones and pulpstones. In order to avoid dupli- cation and, at the same time, show the total production for each classification, the by-products, when they formed the finished product of the mine or (juarry, were added to the classification of which they formed a part. The following statement gives the iiiuintity and value of the by-products that it was possiltle to segregate, the names of the classifications to -which (hey were added, and the classification under which the PLAN AND HCOPE ()F INQUIRY. 25 employees, wages, and expenses incident duction are included: to thf ])ro- PRODUCTION.

Long tons. 11,483 As shown hy this statement, there are 18 of the classi- fications of minerals for whicli tlie values are increased b}' the inclusion of products obtained in connection with products included under other classifications. For instance, the total production of barytes amounted to 61,668 short tons, valued at 1203,154. Thi.s includes 5.39 short tons, valued at $1,618, ol)tained as a by-product from lead and zinc mines. The employees, wages, and other expenses incident to the production of this by- product ai-e included in the totals for lead and zinc ore. On the other hand, the production of lead and zinc was valued at $14:,600',177, which includes 1,625,813 pounds, valued at $37,212, obtained as a by-product from the mining of barytes, the emploj^ees, wages, and expenses incident to the production of this by-product being- included in the statistics for ijarj'tes. In other words, the products of certain mines were segregated so as to show the total production for a given mineral, irrespec- tive of the class of mines from which it was obtained. This practice is in harmony with the methods of the United States Geological Survey, and the reason for its adoption was to obtain totals which would agree with the totals of that office. This method has been followed consistently in the statistics for all minerals except for argentiferous ores. Such a large percent- ao-e of silver, copper, lead, and zinc is obtained from the same ores that it was impracticable to segregate their values, and at the same time to present products which would be in any degree compai'able for em- ployees, wages, and expenses incident to their production. The totals for these minerals, therefore, present all of the statistics for the mines included in each classifica- tion. In treating the difl'erent ores, liowever, the production has been segregated so as to show the total for each metal. While the theoretical accuracy of this method of tab- ulating the reports ma}' be disputed, for the reason that it has resulted in assigning to some minei-als a larger number of emploj'ees and a greater expense than are incident to their production, it is the only practicable way of presenting the data. It permits of a gent.'ral summary for all minerals in each state and in the United States, and shows true conditi(jns as to employees, wages, expenses, quantity, and value of the different products. A similar method was followed in classifj'ing the re- ports for some minerals in which a manufacturing proc- ess is carried on in connection with, and incident to, the mine or quarry. Instances of this character are. ^hen limestone quarrying and cement manufacturing are done at a quarry and a part of the product of the quarry is sold in its crude state for building and other purposes, or when grindstones are made at a sand.stone quarry and a portion of the quarried stone is sold for building or other purpo.ses. Such quarries made only one re- port to the Bureau of the Census, and this was classified according to the product of chief value, the quantities and values of the different products being tabulated and presented separately' in the reports on each mineral. For convenience in treatment the statistics for allied minerals or minerals used for similar purposes are grouped and discussed as a total and also individually. For instance, the report on "Abrasive materials"' in- cludes oilstones, whetstones, scythestones, grindstones, pulpstones, buhrstones, millstones, pumice, infusorial earth, tripoli, crj-stalline quartz, garnet, corundiuii. and emeiy. A number of the substances usually included in re- ports on mineral products are the result of manufactur- ing processes, and therefore should not be included with statistics for mines and quarries. There are also a number of minerals that were not produced in com- mercial quantities in the United States during the year 1902, and therefore no statistics concerning them are given in tliis report. The following summary shows the classification adopted for each mineral, the character of the substance included, and also the names and character of the sub- stances omitted and the reasons for such omission. Abrasive materials: This classification includes (1) abrasive materials that occur as rock formation and are cut and manufactured directly into the form desired, while retaining theii' original roclv structure and appear- 26 MINKS AND QUARRIES. ance. as oilstones and grindstones; (3) alirasive materials that oecur as a constituent of either a rock or a vein and have to lie mechanically separated from the associiited minerals and cleaned, as corundum, emery, and garnet. Uu/i /■stones (iny the solar or artificial evaporation of alkaline waters. It, as well as salt, was classed as a manufactured product at the census of 1900. The sta- tistics, therefore, are omitted from this report. The entire production, J:,900 tons of refined soda ash, val- ued at $50,000, for the j'ear 1902 was obtained from one establishment, the In3'o Development Company, of Inyo county, Cal. , with general offices at (jarson City, Nevada. Carhorandum: Is a product of manufactures, and, therefore, not included in this report. Its composition is, carbon, 32 per cent; silicon, 68 per cent. It comes from the furnace in the shape of black cr^^stals, which are crushed, washed, dried, and sifted to uniform size. At the factory of the sole manufacturers, at Niagara Falls, the production in 1902 was 3,741,500 pounds. Celestite: See Strontium ores. Cement: The statistics relate only to the cement — Portland and natural rock — manufactured by establish- ments engaged in quarrying, but in addition to this product the total production of cement as reported to the Geological Survey is also mentioned. The marl excavated and used for cement is shown here, and not under Marl. The manufacture of pozzuolana, or ce- ment from furnace slag, is not included. Chromic iron ore: See Steel hardening metals — Chrome ore. Clay: Includes kaolin, ball claj^, fire cla}^, slip clay, stoneware clay, pipe clay, terra cotta, and other varie- ties of clay mined and sold as such. The statistics do not include the claj" mined by operators who consume their output in the manufacture of brick, pottery, and other clay products. Coal: Both the anthi-acite and the bituminous coal mines arc included in this classification, the statistics being presented separatel3^ Under h)iturninous is in- cluded semibituminous, lignite, and some coal locally known as anthracite. The anthracite is Pennsylvania anthracite, which is practically the whole production. The totals for bituminous coal include the output of the irregular, small producers. Colialt: See Steel hardening metals — Nickel and cobalt. Colce: Coke is not shown, because a manufactured article and reported as such at the census of 1900. Cojjpt-r ore: The statistics of employees, wages, and expenses relate to the mines producing copper as a product of chief value; but the total quantity and value of the copper obtained from all ores, including the product of silver mines, is included, the amounts obtained from the difi'erent classes of ore being given separately. (See Gold and silver.) Corundum: See Abrasive materials — Corundum and emery. Crnshi d steed : This is a manufactured product and therefore not included in this report. It is used by granite and marble cutters; also in sawing, grinding, rubljing, and polishing stone, and by glass grinders. The sole producers manufactured 735,00(1 pounds in 1902. Cryolite: There was no production of this mineral in the United States in 1902. It is a fluoride of sodium and aluminum, found almost exclusively in Greenland and sometimes called Greenland spar. It is used in the manufacture of aluminum and sodium salts. Crystalline quarts: See Abrasive materials. Dolomites: See Stone — Limestones and dolomites. Eiaery: See Abrasive materials — Corundum and emery. Feldspar: See Flint and feldspar. J^erromanganese: This is an alloy of iron and man- ganese used in the manufacture of Bessemer steel. It is a manufactured article and therefore is not included in census mining statistics. Fdrrous tide: See Talc and soapstone. Fire clay: See Clay." Flint: See Flint and feldspar. Flint and feldspar: This classification includes the flint or quartz mined as such, but does not include the crystalline quartz used for wood finishing or the manu- facture of scouring soaps, which is shown under the class of Abrasive materials. Statistics are also shown for the entire production of feldspar, which is used largely in the pottery and porcelain industry and in the manufacture of scouring soaps and wood fillers. 28 MINKS AND QUARRIES. Fluorspar: Fluorite of fluorspar is a calcium fluoride that is generally found in veins in limestones, sand- stones, mica slate, clay, slate, and gneiss. The statis- tics cover the entire production, i^ractically all of which is used as a fluxing material in steel works and blast furnaces. Fuller's eartli: The greatest part of this earth — a material resembling claJ^ but commonly lacking plas- ticity — is obtained in the vicinity of Quincy, Fla. The entire production is included. It is used in fulling wool and deodorizing and clarifying fats, oils, and greases. Kefineries of lard, cottolene, and allied prod- ucts are important consumers. Garnet: See Abrasive materials. Gold and sllrer: The statistics for gold and silver embrace both deep and placer mines and development work, and also the reduction mills and ore dressing works. In manj' instances gold and silver, and in some cases copper and lead, are obtained from the same ore. The statistics of employees, wages, and expenses for the precious metals are, therefore, presented in the same tables, but the production of each metal is shown separately. The A'alue of the product is the value at the mine to the miner. Granite: See Stone — Siliceous crystalline rocks. Grapldte: This mineral is sometimes called plum- bago, black lead, or pot lead. It occui-s as a form of carbon, and is the last form assumed in the natural change of vegetable matter into a mineral. The statis- tics include only the production and retining of the natural graphite, which is classed either as crystalline or amorphous. Greensatid marl: See Marl. Grindstones: See Abrasive materials — Grindstones and pulpstones. Grindstones and pulpstones : See Abrasive materials. Gypsum: The statistics cover the crude gypsum — a calcium sulphate — marketed as such; also the product ground into land plaster and that calcined into plaster of Paris and wall or cement plaster. Ilulmerite: See Steel hardening metals — Tungsten. Infusorial earth, tri/ioli, and jmnuce: See Abrasive materials. Iridium: See Platinum and iridium. Iron ore: The statistics include the difl'erent varieties of iron ore generally classed as (1) red hematite, includ- ing all anhj'drous hematites, known b}' various names, such as red hematite, specular, micaceous, fossil, slate iron ore, martite, blue hematite, etc.; (3) brown hema- tite, inchiding the varieties of hydrated sescjuioxidc of iron, recognized as limonite, gothite, turgite, bog ore, pipe ore, etc. ; (o) magTietite, tliose ores in which ii'on occurs as magnetic oxide and including sume martite, which is mined with the magnetite; (4) carl)onate, tliose ores which cfintaiii a considerable amount of carbonic acid. sii(;li as spathic ore, hlackbaiid, siderite, cIun', iron- stone, etc. The statistics for mano-aniferoiis ii-on ores are also included. Argentiferous manganiferou> iron ores are included in some cases with iron ores and in other cases with silver, according to the relative com- mercial value of the silver and iron contents. Kaolin: See Clay. Lead ore: See I,iead and zinc ore. Lead. and. sine ore: Only nonauriferous and nonar- gentiferous lead and zinc ores are included. It is im- practicable, in a majority of cases, to separate the statistics of employees, wages, and expenses incident to the production of each metal, and they are combined in the tables, liut the quantity and value of each, and, in some cases, other statistics are shown separateh*. Totals for both lead and zinc include the dressing of the ore at the mine preparatory to its treatment at the smelter. The value is that of the contents at the mine to the miner. A considerable proportion of the lead product is obtained from silver ore, which carries with it also some gold. All the statistics relating to argen- tiferous lead ores, including the value of product, are given in the report for gold and silver mines, shown under Gold and silver. Lepidolite : See Lithium ore. Limestone: See Stone — Limestones and dolomites. Lirnestrjnes and deilouiitcs: See Stone. Litharge: This is a lead pigment, classed with white lead, red lead, etc., and being obtained by a process of, manufacture is not included in statistics of mining. Lithium ore: The two minerals thus far mined for their lithium contents are lepidolite and spodumene. Lepidolite is a lithia mica, in part a metasilicate of aluminum with potassium and lithium and varying amounts of fluorine and hydroxvl. Spodumene is a metasilicate of aluminum and lithium, generallv con- taining a little sodium. It is not the metal lithium that is used in the arts, but its salts, principally lithium carbonate. This is used extensively in the preparation of mineral waters for medicinal purposes and in the manufacture of efl'ervescing lithia tablets. L-^itlaigrajdiie stone: This is an even grained, compact limestone, usually of a drab or bufl' color, like that quarried at Solnhofen, Germany, and is used by lithog- raphers. No production was reported for the vear 1902. A report was received from a quarry in Kentucky that did only development work and prospecting. Lith- ographic stone has ])e(Mi found in Talladega county, Ala. ; in Kern county. Gal.; in Illinois; at Anamosa, Jones county, and in Van ISuren county, Iowa; near Elizabeth- town, Ilardin county, and in Clinton, Estill, Kenton, Rowan, and AVayne counties, Ky.; at Saverton, Kails county. Mo.; in Clay and Overton counties, Temi.; and in Llano county, Tex. The world's supplj-, however, has been obtained mostly from the quarries at Soln- hofen, Bavaria. The imports for the year ending Jime 30, 19(»3, were valued at $^131,(115. Magnesiti': This is magnesium carlionate. The min- ing is confined to California.

The mineral is used especially" in the manu- facture of magnesite bricks for the refractory lining- of furnaces and the manufacture of carbon-dioxide gas. When crude magnesite is decomposed by sulphuric acid there is a by-product of magnesium sulphate, or Epsom salts. Both crude and calcined magnesite are included in the statistics. Manganese ore: The statistics for manganese ore include ores carrying over -±-±.3 per cent of metallic manganese. The manganiferous iron ores are treated under ''Iron ores," and the manganiferous silver ores in some cases under " Silver" and in other cases under " Iron ores," according to the relative commercial value of the silver and iron contents. The chief vise of man- ganese is in the manufacture of Bessemer steel. Marble: See Stone. Marl: Marl includes the green, blue, red, and yellow clayish earths used as fertilizers. The marl deposits extend from New Jersej' to North Carolina, but the mines included in the statistics are in New Jersey and Virginia. In New Jersey the entire product is applied to the soil in the natural state, while in Virginia it is dried and ground for use in commercial fertilizers. Mica: There are two varieties of commercial value — muscovite and phlogopite, but the former is more commonly found and mined. The value of mica de- pends on its occurrence in blocks or masses that are capable of being split into sheets a square inch or more in size, and the value of these sheets increases with their size, which varies from 1 inch square to 8 by 10 inches. Soap mica, ground to a tlour, is used in the manufacture of wall papers, lubricants, fireproofing materials, novelties, etc. Sheet mica is used chiefly in stoves, for chimneys of incandescent lights, and for the insulation of electrical apparatus. The statistics emVjrace both sheet and scrap mica. L considerable proportion was mined h\ small, irregular operators, and the statistics for them are included in the total. MUhtonen: See Abrasive materials — Buhrstones and millstones. Mineral paints: See Mineral pigments, crude. Ifineral pigments, crude: Include the production of ores used in the manufacture of mineral paints. They consist of iron ores (red and brown hematites) that are ground and used in the manufacture of metallic paint, and are not included in the production of iron ores for the manufacture of iron; clay or other earths, includ- ing some mined as "Venetian red," containing iron used in making yellow, red, and brown pigments (such as ocher, umber, sienna, etc.); carbonate of zinc, slate (or shale) and soapstone, ground for pigment. No statis- tics of manufacture are given except such as are insep- arable from the mining. Mineral waters: The report on manufactures of the Twelfth Census and the annual reports of the Geological Survey contain statistics concerning the production and sale of mineral waters. These statistics have been omit- ted from the census of 1903 for the reason that mineral waters ai'c not commercially classed as the product of a mine or (juarry. They are produced under conditions that are entirely different from those pre^'ailing in the nrining industries. The employees engaged in the in- dustry are devoted almost exclusively to the prepara- tion of the product for the market, as there is practi- call}' no expense incident to the production of the water itself. The total production for 1902, as reported bv the Geological Survey, was 64, 8.59, 4.51 gallons, valued at $8,793,761. Molybdenum: See Steel hardening metals. Monazite: This mineral is essentially an anhydrous phosphate of the rare earth metals cerium, lanthanum, and didymium. It is mined for its thoria contents, which are usually from 3 to 9 per cent, but have been found to vary from a fraction of 1 per cent to 32 per cent. The commercial deposits of monazite are found in placers of streams and rivers, also in old sand and gravel deposits of former streams, and are worked by sluic- ing the sands and gravels, principally b3' small, irregu- lar operators, just as placer gold is washed. The thoria in the monazite and, in much smaller qu.antities, the lanthanum and didymium are used in the manufacture of the cylindrical hood or mantle of incandescent gas- lights. The cerium oxalate obtained in the separation of the oxides is used in pharmac}'. Nataral gas: The statistics relate exclusiveh' to the production of natural gas, and the value of the product is the value at the point of consumption. The jDetro- leuni pi'oduced by gas companies and the statistics per- taining to it are included in those for peti'oleum. Nickel: See Steel hardening metals — Nickel and cobalt. Nichel and cobalt: See Steel hardening metals. Nitrate of soda: No production of nitrate of soda was reported for the United States during the year 1902. A schedule was received from one California company owning a mine in Nevada, at which develop- ment work only was done. The world's supply is ob- tained principally from the natural beds of Chile. The total imports from all sources for 1902 were 661,348,800 pounds, valued at $5,996,205. Novacidite: See Abrasive materials — Oilstones, whet- stones, and scythestones. Oclier: Ocher is a pigment used in the manufacture of mineral paints. See Mineral pigments, crude. Oilstones: See Abrasive materials — Oilstones, whet- stones, and scythestones. Orange mineral: This is a lead oxide pigment largelv used for paints. Being classed as a manufacture, it is not included in Census mining statistics. Ozocerite: This mineral is also known as mineral wax. No production of the mineral, as such, was reported 30 MINES AND QUARRIES. for 1902. The entire product is obtained in the treat- ment of asphaltum, and therefore is classed for census purposes as a product of manufacture. Petroleum: The statistics relate exclusivel}' to the production of crude petroleum. Petroleum refining is classed as a manufacture, and the statistics are included in the census of manufactures of 1900. The produc- tion of natural gas by petroleum companies has lieen eliminated from the reports for such companies, and the statistics are included in the classification of nat- ural gas. Phosjyhate rock: This is a name given to various mineral deposits, consisting largely of calcium phos- phates or iron and alumina phosphates, and used in the manufacture of commercial fertilizers. The statistics include the preparation of the rock for market when this is done at the quarry. Pig iron : This is classed as a manufacture and was shown at the census of 1900. It is not included in mining statistics. Pipe day: See Clay. Platinum: See Platinum and iridium. Platrnum ,, quartz, porphyry, and trap. These are used for various purposes, such as building stone, founda- tion work, monumental stone, paving blocks, curb- stone and flagstone, rulible and crushed stone for riprap, macadam roads, concrete, and railroad bal- last. The kinds of stone treated under trap rock are trap, diabase, and diorite, which are quarried exten- sively in the New England states, and in New York, New Jersey, and Penns^dvania, and are used largely for paving stones and road metal; l)asalt, quarried in California for the same purposes; and galibro. Slate: Slate is quarried principally for roofing, but also for manufacture into slabs, slates, slate pen- cils, etc., the milling necessarily being- done at the quarries while the stock is wet. Slate ground for pigment is included in Mineral pigments, crude. Stoiieirare chnj : See Clay. Strontlanite: See Strontium ores. Str rod': See Stone — Siliceous crystalline rocks. Tripoli: See Abrasive materials — Infusorial earth, tripoli, and pumice. Tungsten : See Steel hardening metals. Uirdjer: Cmber is a pigment used in the manufacture of paints.

Venetian red: See Mineral pigments, crude. ^¥hetstoneH: See Abrasive materials-Oilstones, whet- stones, and sc_vthestones. AWliite lead: White lead is classed as a uianufacture, and not shown in the census mining statistics. Wolframite: See Steel hardening metals-Tungsten. Zinc ore: See Lead and zinc ores. Zinc white: This is a manufacture, and not included in tlie mining census. There are many varieties of ores and metals included in the different groups or classifications. These ores and metals have been described with more or less detail in the reports for each classification. ))ut in order to assist in the identification of the ore, the metal, and its chemical constituents, the following table, with the ac- companying descriptive text relative to all ores of economic importance, is given:' ORES i)F ECciNdMIC IMI'l )KTANCE. The accompanying taVjle has been compiled from several authori- tative sources,''^ the ores under each metal being arranged in the order of mineral species given in Dana's System of Mineralog}', sixth edition. The percentage compositions given in that work have been adopted and the metallic content has been calculated therefrom where necessary. In a mining region one often hears ores spoken of as running 90 per cent lead, 80 per cent zinc, and so on, when the purest crystallized minerals do not contain such amounts of the metals. The fourth column of this table shows the highest possible percentage of metal in the various ores, and the fifth column indicates the corresponding amounts of metal in the short ton (2,000 pounds) of pure ore. In a few instances the ore is of such variable or uncertain composition that the highest per- centage of metal given by actual analysis has been quoted, instead of any theoretical amount. This has been indicated in the table Ijy the use of brackets. It must be remembered, liowever, that, with the exceptiim of some ores of iron, tin, and quicksilver (mercury), the metalliferous ores as found in run of mine are not pure or unmixed minerals; on the contrary, they are in complex associations with one another. This is especially the case with silver ores (of which there are some thirty varieties, counting rarecomliinations), and, to a smaller degree, with ores of gold, nickel, antimony, zinc, and some other metals. Often it is the constituent of luw ratio but high pecuniary value in thesi' mixed ores that makes tlic mine worth working; or sucli a constituent may lie the by-product of reduction which makes mining profitable. Furthermore, even with relatively pure ores, the accompanying gangue minerals — for instance, quartz, ealcite, barite, and fluorite — seldom can be wholly removed by hand sort- ing or other means of concentration. These impurities and the unavoidable losses during the processes of reduction make the amount of metal actually won from an ore fall far below its theoret- ical cheniical composition. The principal use of the table is to show the highest possible amount of metal that could be obtained from pure ores.

In addition, the other expenditures aggregated $115,871,135.""^ In 1902 there were 38,128 salaried ofBcials, clerks, etc., with salaries amounting to $39,020,552. The aver- age number of wage-earners employed during the entire year was 581,728, and they received in wages $369, 959, 960.' The miscellaneous expenses and cost of supplies and materials amounted to 1195,586,680, and vass was made at the Eleventh Census, which covered the products were valued at $796,826,117. The prod- the year 1889, but the results were not summarized nor were the data, except for the quantity and value of products, compiled on uniform lines. The only information concerning the employees, wages, and other expenses for all branches of mining published at the Elleventh Census is contained in the following statement taken from tht; text of the report: " In all, 636,119 persons found employment directly in the mining industry, and depended upon this industry as their regular means of support.

The number of persons who foiuid employment directly in the mining- industries at the Eleventh Census was evi- dently reported on a difterent basis from that used at this census. The average number shown for 1889 was the average number employed during the time the mine was in operation, while the average number shown for 1902 is the average number for the whole year, whether the mine was in operation all the year round or a part of the time only. The value of products reported for the census of 1902 is the amount received by the mine operators, and should not be confused with the value of the finished mineral product or the refined metallic contents of the ore, such as iron, antimony, and nickel. The quantity and value of the refined metallic contents and the coining value of some ores, such as g-old and silver, are given for 1902 in Table 1 in order to ol)tain comparable totals. The separate quantity and value of gold, silver, copper, lead, or zinc, when, as frequently happens, two or more of them are obtained from the same ore, can not be definitely deter- mined until the ore has been smelted. Smelting is a manufacturing process, and is therefore omitted from the mining census, but the metallic contents of the ore and bullion produced in continental United States during the year 1902 and the gross value of the same, as computed from the reports to the Bureau of the Census, were as follows: Gold, 3,242,039 ounces, valued at $65,628, 90«; silver, 55,819,946 ounces, valued at $28.- 166,094; copper, 639,033,392 pounds, valued at $71,- 192,014; lead, 338,125 short tons, valued at 118.181.013; zinc, 527,121 short tons, valued at $9,006,361. These values are the values at the mines. Gold and silver were reported at the Eleventh Census in troy ounces and coining value. Computed on the same basis, the production of continental United States for 1902 amounted to 3,242,039 ounces of gold, valued at $67,- 018,890, and 55,819,946 ounces of silver, valued at $72,171,227. No canvass of the gold mines of Alaska having been made by the Bureau of the Census, the estimate for Alaska made by the Director of the Mint is accepted In* this office. The total production (if the United States for 1902 is accordingly estimated as follows: Gold, 3,645,769 ounces, valued at $75,3ri4,69(.»; silver, 55,911,946 ounces, valued at $72,290,176. The Director of the Mint reports the production of gold for the United States for the calendar year 1H02 as 3,S70,000 ounces, valued at $80,000,000, and the production of silver as 55,5<.»0,000 ounces, valued at $71,757,575. The disparity in these results is due to the fact that the Bureau of the Census collected the data directly from the mines, while the Director of the Mint obtained the inforujation from mints, assay offices, private refineries, and other sources. The quantities and \'alues reported b\' tlie Director of the Mint lepresented the refined product, a portion of which may have been mined during the preceding year; and, moreover, since a por- tion of the product reported by the Bureau of the Cen- sus as mined during 1902 would be included in the report of the Director of the Mint for the following year, the totals for the two offices for the same year can not agree. The increase that has occurred in the production of the difi'erent minerals during the thirteen years covered by Table 2 is referred to in the discussion of the statis- tics for each mineral on pages 393 to 1071. Reference should be made to these separate reports for more detailed information. As no statistics for employees, wages, or expenses incident to the production of cement, clay, feldspar, fiint, rutile, borax, or slate ground as a pigment are given in the report of the Eleventh Census, it w'as necessary to take the production for these minerals for 1889, as shown in Table 2, from the tabulation of the mineral products of the United States, apparently pre- pared, in some respects, independently of the regular census work, but presented in the introduction to the report. The Eleventh Census did not present statistics of any character for bauxite, crystalline quartz, fuller's earth, lithium ore, magnesite, molybdenum, monazite, tung- sten, or uranium and vanadium, these minerals not then being produced in commercial quantities. Silica sand which is usually the product of sandstone quarries was included under the classification of sandstones, while garnet was included in abrasives.

Antimony has not yet been uncovered in any of the .states in sufficient ([uaiitity for development. The known deposits of the mineral are associated with other metals fliut so predominate as to prohibit the exploita- tion of antinionv as such. SUMMARY AND ANALYSIS OF RESULTS. 39 While lliere was a slight decrease in the vahie of corundum and emery produced in 1!»()'2 as compared with 1889, a gi-eat increase occurred in the tonnai^^^e. The averaye price per ton of the product diKu-eased during- the period of thirteen years nearly one-half. The manufacture of an artificial a})rasive as a substi- tute for corundum and emery has had its cticct upon the value of the natural matcu-ial. There was no production of lithographic stone in the United States during li»02, no beds having been found that furnished stone of suiticient i)urity or adeipiate iiize. The substitution of plates of zinc and other metals, and the importation of lithographic stone, prin- cipally from Bavaria, satisfied the demand. The deposits of manganese ore found in th(^ United States are combined with siliceous and phosphorous substances to such an extent that the production can not compete with the foreign ore. Moreover, the deposits are located in isolated places, where transi)ortation facilities are inadequate. These disadvantages have resulted iu a decrease in the pi-oduction of domestic manganese ore as compared with the production of 1889, although the product in 190ii was the largest since 1891. The decrease in the production of marl is due to the greater substitution since 1889 of fertilizers made of phosphate rock and other materials. About two-thirds of the production of 1903 was obtained from New Jer- sey and was consumed locally. The indicated decrease in the production and value of crude mineral pigments is more apparent than real. The statistics for 1902 are to a considerable extent for the crude product, while the production shown for 1889 included the value of large quantities of refined material or manufactured paint. As a matter of fact, the mining of mineral pigments is progressing steadily. Ozocerite (native paraffin), or a mineral closely related to it, was reported some years ago to have been found in Utah, but according to the report it could not be produced continuousl_v in commercial quantities because it could not compete with the ozocerite imported from Austria. This Utah ozocerite constituted the produc- tion reported in 1889. It is said now to be exhausted. '"Immense quantities are extracted from the crude petroleum found in the Pennsylvania and Lima (Ohio) fields." ' This, as paraffin wax, is included in the prod- ucts of petroleum refining. The group of "all other minerals" shown in the above statement, includes chrome ore, nickel and cobalt, and rutile, but as there were only two operators i-eported for nickel and cobalt and one each for chrome ore and rutile, the production of the different minerals can not be shown without disclosing the operations of individ- ual operators. All of these minerals show a decrease when compared with the production of 1889. Many ' United States Geological Survey, United States," 1902, page 596. "jMineral Resources of the deposits of chrome ore can not be mined on account of the low price at which the foreign ore is imported. There ai'e oid\' a few nickel ore deposits in the Ignited States, and these can not be worked to advantage at the prices prevailing for refined nickel, and in competi- tion with the more proHtal)]y worked nickel oi'e de- posits of Canada. Co})alt is closely associated with the nicU'el in the ores fi'om which these metals are obtained. A small production of rutih; satisfies the demand. The quantity has inci'eascd, Init there has been a large falling off in the value of the total product mined. Earh/ (Iri^'htpuient. — Mining was not an impoi'tant feature of the early development of the United States, and until comparatively recent years information con- cerning the mineral products of the country was verj' meager. Agriculture was the predominating industry of the entire covintry at the opening of the nineteenth century; later, manufactures received greatest atten- tion in the Northern and agriculture in the Southern and Western states. Numerous exploring expeditions were conducted during the eaily history of the country for the purpose of locating mineral deposits. Reference is made in the reports of these expeditions, to the min- eral deposits in the region of the Great Lakes and the jNlississippi valley. " During the eighteenth century a number of mining operations wei'e undertaken and cai'ried on in different parts of the country, ajiparently with l)ut little sui'cess."- Tbe history of coal mining in the United States affords a good illustration of the general development of the mining industry. In 1820 the first cargo of anthracite coal was sent to Philadelphia. The annual consumption of all coal in 1817 has been estimated at 3,0(»0,00O tons;' in 1902 the production of anthracite coal amounted to 11.370,595 short tons and the produc- tion of bituminous coal to 260,216,81:1 short tons, making the total production 301,590.139 short tons. The smelting of iron ore appears to have been carried on to some extent in Massachusetts as early as 1702.' The production of iron ore in 1810 has been estimated at more than 300,000 tons, and the production of pig ii'on from the ore in Pennsylvania amounted to 98.395 tons.' The Lake Superior region was opened in 1811 and about S(,»0 tons of blooms were shijjped from the region in 1853."' In 1902 the production of iron ore in Penn- sylvania amoimted to 822,932 long tons and in the Lake Superior region to 26,977,101 long tons, the production of the two districts amounting to 27,800,336 long tons, or 78.2 per cent of the 35,567,110 long tons reported for the United States. EarU in the nineteenth century gold was mined to some extent in North Carolina, and for a numl)er of 2 The Metallic Wealth of the United States, by J. D. Whitney, page xxiii.

But few at- tempts at regular mining were made prior to 183-1-.' The discovery of gold deposits in California in 1848 gave an impetus not only to the search for precious metals, but also to mining enterprises of all kinds throughout the country.' The production of domestic gold in 1853 deposited at the United States Mint and its branches was valued at $55,622,051, $55,113,487 of which value was obtained from California.' The pro- duction for 1902, as reported by the Director of the Mint, was valued at $80,000,000. Operations in the copper region of Lake Superior began as early as 1771, but particular attention was not directed to that field until 1844.* Its production of pure copper for 1854 has been estimated at 2,000 tons.'' The production of the same region in 1902 was 171,102,065 pounds, or 26.8 per cent of the 639,033,392 pounds reported for the United States. Mining in the Missouri lead field appears to have begun as early as 1720, but was not followed in a regu- lar manner until 1798. By act of Congress of March 3, 1807, all the government lands containing lead were ordered to be withheld from sale, and leases were authorized instead. The issuing of leases began in 1822. After 1834 smelters and miners refused to make pa3'ments because of the great number of illegal entries of mineral land, and in 1847 Congress authorized the Land Office to sell the lands outright. In 1839 a geo- logical survey of the lead region of the upper Mississippi valley was authorized bj' Congress. In l.slo the pro- duction of the upper Mississippi and Missouri regions was estimated at 14,780 tons." In 1902 these regions produced 131,606 tons. The greater part of the lead product of the United States in 1902 was obtained from argentiferous ores. The history and occurrence of the various minerals in the ditt'crent states are referred to in the discussion of the statistics for each state, on pages 163 to 346. The importance of the mining industries is due not onl}' to the magnitude of the aggregate production, but also to the great number of ditferent minerals mined and the numerous uses to whicli they are applied. The development of these industries lias occui'rcd \'ery largely since 1880, as manjr of the minerals eiuunerated in this report were not mined in commercial cjuantities before that year. Exclusi\'e of coal, pig iron, copper, lead, petroleum and natural gas, stone, (|uicksilver, limestone for iron flux, zinc, and the pr(_'ciuus met- als, the mineral products of the country in 1880, as reported by the (Geological Sui'\'ey, w(M-e valued at only $37,567,133. The corresponding value f(jr l'M}-j, was $82,395,444— an increase of $44,828,311, or 119.3 per cent. The existing diversity of metals is largely the result of processes applied to the reduction of the minor metalliferous minerals; while the great absolute increase in quantity and value of mining products, in number of people employed and in yearly wages paid, is due mainly to the development of the major min- erals, the great variety of uses to which the minor ores and the metals derived from them can be put has fur- nished a constant incentive to increase their production. Table 8 presents statistics for 52 classifications of minerals. From these, however, there are obtained a large number of metals and other substances, each distinct in character, as the result of processes applied directly to the mineral or ore. There are also a nuiltitude of other substances obtained by their use as bases for chemical combinations and manufacturing processes. The organization of the United States Geological Survey in 1879 was the first step in the scientific inves- tigation of the mineral deposits of the country as a whole. The general desire for information concerning the mineral resources of the country has been satisfied in part by systematic geological investigations in sev- eral of the states, beginning as early as 1823. At a still earlier period investigations were carried on by private enterprise, generally limited to minerals of well-known market value, such as iron, gold, silver, copper, and coal. The need for information concern- ing the location, character, and extent of the deposits of these minerals was fully appreciated liy the organ- izers of the Geological Survey, and it is evident from the estimate submitted to Congress for the work of the office for the fiscal year ending June 30, 1881 — the second 3'ear of the Survey's existence — that exhaustive preparations were made for the collection of informa- tion conceiTiing all classes of minerals and the geolog- ical structure of the entire countrv.' • The Metallic Wealth of the United States, by J.

The produc- tion of pig iron in the United States in 1901 was 15, 87s, 35-4 gi'oss tons, as compared with 7,928.647 gross tons in Great Britain and 7,73H.6t:)3 gross tons in Ger- many, the production of the United States thus exceed- ing the combined production of the two countries by 213,044 gross tons. The statistics of 1902 for Great Britain and Germany are not available, and therefore no comparative ligui'es for that year can ])e given. The production of silver in the United States in 1902 was valued at 171,757,600 (coining value), as compared with $108,343,000 for Spanish America.

As elsewhere explained, some of the sulistances in- cluded in the general groups by the Geological Survey are not covered liy the census of mines and quarries. Further, the a.ssignnient of the different minerals to the respective groups should not always lie accepted as an exact segregation. For instance, petroleum is a.ssigned to the group of fuels, ))ut a considerable pro- portion of the refined product is used for other pur- poses. Ill like manner, the group of "structural materials" includes all stone, although some sandstone is crushed and used in the puh'crized form in the man- ufacture of glass, and a consideralile amount of lime- stone is used for iron tlux, for the manufacture of lime, and for roadmaking. There is, in fact, hut slight con- nection between the totals for any of the groups other than their general relation to the industrial progress of the country. It is interesting, however, to note the proportion which each of these groups contributes to the gciK'ral totals for all mines and t|uarries. These proportions are shown in Table 9.

Fuels are by far the most important group of minerals. Their production g-ave employment to 64.1 per cent of the wage-earnert;, and the value of the products belonging to the group formed 58.9 per cent of the total value reported for all minerals. The pro- duction of coal alone gave employment to more than 100,000 wage-earners in excess of the number employed in the production of all other minerals combined; the wages paid by operators of coal mines exceeded those paid by all other operators by S70.4.36,s4l': and the value of the annual production of coal was within f6i\ 762,279 of the value of all other minerals. The metalliferous minerals rank next in importance. The \'alue of the crude metiillic ])roducts constituted 27 per cent of the total value of products, and their pro- duction gave employment to 19 jDer cent of the wage- earners. This group is composed of the various ores and metals enumerated under the term "metallic" in Table 9. Of the.se, iron ore is the most important from the standpoint of ivage-earners, and gold and silver the most important measui-ed by value of products. Of the 110,404 wage-earners reported for the group, 38,851, or 35.2 per cent, were employed in the produc- tion of iron ore, and they received §21,531,792, or 25.6 per cent of the total wages for the group. The value of the iron ore produced was reported at $65,465,321, or 30.4 per cent of the total for the group. The gold and silver was valued at the mine at $82,482,052, which is 38.3 per cent of the total for the group, exceeding the value of the iron ore by $17,016,731. But on the other hand the number of w'age-earners engag(>d in the production of iron ore exceeded the number for precious metals by v.7(i<.). The wages, however, foi' precious metals exceeded those paid for iron ore by $14,.545,70(). iStructural materials ranked third in importance. This group includes marble, granite, and other stones and embraces a great variety of products. The production of structural materials gave employment to 14. M per' <'ent of all wage-earners engaged in the mining indus- tries, and the wages of these employees formed 12 per cent of the total wages. The value of structural materials quarried amounted to 12. 1 per cent of the total value of the products of all mining operations. While the other groups enumerated in Table 9 — ab- rasive materials, chemical materials, pigments, and miscellaneous substances — are important from the stand- point of the variety of their products and the uses made of them, the wage-earners engaged in their production and the value of their products form a very small proportion of the totals for all minei-als. Miiiernl proijiicfs Inj sfatrs. — The contribution of each mineral and group of minerals to the aggregate for the United States ha\ing been considered, it may be of interest to examine th(> contribution of each state to this aggregate, irrespective of the character of the minerals produced. Mineral production is necessarilv concentrated in the states containing the most extensive and most fa\-orably situated deposits. The deposits located con\-eniently for utilization of the products have been de\ek)ped to the detriment of those in less favored sections. Tliese conditions have stimulated the development of the mineral deposits in certain states, and it frequently occurs that practically the entire product of a state is represented by a single mineral. The totals for the diU'erent states ai'e presented in Tables 1() and 11, and the i)roportions are graphically shown in the accompanying diagram. Table 10 shows the general totals for all minerals in each state and territory, while Tai)le 11 presents the value of the min- eral products in each state aiid territory in comparison with the population and the gross value of the products of agriculture and manufactui-es as reported at the Twelfth Census, and tilso the i-ank of the state and the per capita value for each class of products. In addi- tion to the gross value of products this tabl(> shows the net value of the manufactured products; i. e., the gross \'alue less the cost of materials purchased in a iwrtially manufactured f orm. ' ' PVir metlii)(l of ciiiii|uitiii^' net ]iren population and agriculture and between population and manufactures, the per capita value of the mineral products has been included in Table 11 for the jwrpose of making a comparative showing. Pennsylvania, which ranked second in population and manufactures, and eighth in agriculture, was the leading mining state in 1902, both in the number of 52 MINES AND QUARRIES. wao;e-earners emploj'ed and in the value of products. Its high rank was due to the production of anthracite and bituminous coal, the wage-earners reported for the coal mines forming 84.7 per cent of the l!t0.1)35 re- ported for all mines in the state, and the products of such mines forming 76.9 per cent of the total product of $236,871,417. The position of Pennsylvania as the leading mining state was most pronounced. Out of a total of 581,728 wage-earners engaged in mining in the United States, Pennsylvania reported 190,93.5, or 32.8 per cent, who received as wages $11-1, 122,137, or 30.8 per cent of the $3(39,9.59,960 reported as the total. The value of the state's production was equally high, being 1236,871,117, or 29.7 per cent of the $796,826,417 reported for the United States. Prac- tically one-third of the whole mining industrj- of the United States, as measured l)v the persons employed and the value of products, was confined to this state. While it is true that the exploitation of its enormous coal deposits has been responsible for Pennsj'lvauia's position as the leading mining state and that this in- dustry has assumed overshadowing proportions, it is also true that the state has produced a large vaiiety of minerals. Of the 52 classes of minerals reported 23 were found in Pennsylvania, the state being exceeded in this respect only by California, with 26 classes, and by Virginia, with 24. New York, which stood ti)-st in population and in manufactures and fourth in agricidture, was thirteenth in mineral products. The state's mineral industry, em- ployed 1.6 per cent of the wage-earners, paid them 1.4 per cent of the wages, and produced 1.7 per cent of the total value of products. The 5 leading mining industries of New York were cement, limestones and dolomites, pe- troleum, sandstonesand quartzites, and iron ore, ranking in the order named. For each of these classes a pro- duction of over $1,000, 00(» was reported, and the 5 together showed a production of $10,462,663, or 7n.4 per cent of the total for the state. Ohio, which ranked fourth in population, third in agriculture, and fifth in manufactures, held the second position in value of mining products. The total value reported for the state was $57,186,922. Of this amount the product of coal mines formed $26,953,789, or47. 1 percent. The state also held third place in the number of wage-earners, the coal mining giving employment to 25,963, or 69.8 per cent of the 37,173 reported foi- the state. Next to coal, petroleum is Ohio's chief mining industry, the two combined con- tributing over four-tifths of the state's mineral wealth. Michigan, ninth in population, tenth in manufactures, and thirteenth in agriculture, ranked third in mineral products. Witii 40.8 per cent of the total value of the ir(^n ore output of the L'nited States ci'edited to it, Michigan was the leading producer of this mineral, which was the ciiief product of its mines. This indus- try claimed 14,45<; wag(,>-eariiers, or 45.2 per cent of the 31,951 employed in all the mines of the state, yielded them in wages $9,132,763, or 45.4 per cent of the total of $20,103,616; and the product itself was valued at $26,695, .S60, or 53.2 per cent of the $50,157,358 repre- senting the total value of the output. Aftei' iron ore, Michigan's most important mineri(l product was cop- per ore, its output being valued at $18,247,207, a figure that -was exceeded by Montana only. It will be noted that these two ores together were credited with a total value of $44,943,067, or 89.6 pev cent of the I total value of the mineral output of the state. I West Virginia, twenty-eighth in population and agri- culture, and thirty-first in manufactures, was fourth in mineral products. The coal mines of the state gave employment to 23,914, or 79.7 per cent of the wage- earners, and their products formed $24,748,658, or 51.2 per cent of the total value of mineral products reported for the state. In the production of coal. West Virginia ranked fourth, being outranked only by Pennsylvania, Illinois, and Ohio, and the high ranking of these states as mineral producers was due, either wholly or in great part, to this industry. After coal. West Virginia's lead- ing nunerals were petroleum, with an output valued at $17,i»4(.i,3r7, and natural gas, valued at $5,390,l8l. These three industries together account for 97.5 per cent of the reported mineral values of the state. It is interesting to contrast this condition with that of ^Michigan, the one producing, to an almost exclusive extent, fuels, and the other an enormous preiDonderance of ores. C'olorado, thirty-first mi [)opulation, thirty-sixth in agriculture, and twenty-seventh in manufactures, ranked fifth in mineral products. This high position was due almost exclusiveh' to the precious metals of the state. The gold and silver produced in 1902 were val- ued at $29,655,974, forming 73 per cent of the total pro- duction of the state, and 36 per cent of the total value of these minerals in the United States, and thus I'xceed- ing California's production of gold iind silver, valued at $15,473,091, by almost 91.7 per cent. This industry in Colorado gave employment to 11,200 wage-earners, or 54.6 per cent of the 20,519 engaged in mining in the state, and returned to them as wages $11,726,123, or 62.1 per cent of $18,s74,836, the total amount paid in wages. Bituminous coal with a value of production amounting to $8,397,812 ranked second in Colorado's mining industries, and iron ore was third with a prod- uct valued at $1,084,424. Illinois, third in population and in manufactures, and second in agriculture, was sixth in rank as a mining state. Here, also, bituminous coal was the leading- mineral. Its production employed 36,617 wage-earn- ers, or 90.4 per cent of the 40,523 wage-earners engaged in mining in the state, and paid them $24,s76,201, or 92.2 per cent of the $26,9S6,397 paid in wages in the state; and the product itsidf was valued at $33,945,910, or ss.s per cent of the $38,234,410 reported as the total DIAGRAM VI.— VALUE OF MINERALS PRODUCED IN EACH STATE AND TERRITORY: MILLIONS OF DOLLARS PENNSYLVANIA OHIO MICHIGAN WEST VIRGINIA COLORADO ILLINOIS CALIFORNIA MONTANA INDIANA MINNESOTA MISSOURI ALABAMA NEW YORK UTAH ARIZONA KANSAS IOWA TENNESSEE KENTUCKY IDAHO MARYLAND TEXAS SOUTH DAKOTA VIRGINIA NEW JERSEY VERMONT WYOMING WASHINGTON MASSACHUSETTS WISCONSIN INDIAN TERRITORY MAINE NEVADA GEORGIA FLORIDA ARKANSAS NEW MEXICO OREGON SOUTH CAROLINA CONNECTICUT NEW HAMPSHIRE NORTH CAROLINA RHODE ISLAND DELAWARE NORTH DAKOTA DIAGRAM VII.— PROPORTION OF MINERALS PRODUCED, BY GEOGRAPHIC DIVISIONS: 1 902.

Liinostoiu'S ami dolomites, with a product valued at $8,^32,1^3, eoiisti- tutcd the industry second in importance. California, twenty-tirst in population, fourteenth in agriculture, and twelfth in manufactures, ranked seventh in the value of mining products, but led the states in the variety of the minerals, reporting production in ^fi of the 52 classes. It was unique also in the fact that at least two of its minerals, viz, chrome ore and mag- nesite, were mined nowhere else in the Union, and that in others, such as quicksilver and borax, its lead was so great that it may almost ))e said to have stood alone. The leading mineral products in California were gold and silver, valued at $1.5,473,091; petroleum, $4,873,(317; borax, $2,370,994; copper ore, $1,. 599,663; quicksilver, 11,295,740; and siliceous crystalline rocks, $1,137,679. The state had 6 distinct mineral classifications, for each of which an output of over $1,000,000 was reported. Its leading mineral product, gold, although of less value than when it won for the state its title of •"(xolden," is still of greatest importance. In the mining of gold and silver there were employed 7,989 wage-earners, or 61.6 per cent of the state's l2,9t!4 wage-eai'ners engaged in mining; and these received as wages $7, lol, 003, or 64.3 per cent of the $11,050,666 paid as mining wages. Of the state's total output of all minerals, valued at |2s, 870,405, the precious metals cont)-i))uted$15, 473,091. or 53.6 per cent. California's production of gold anrl sih'er amounted to 18.8 per cent of the total value of the products of this industry in the United States, and was second oidy to that of Colorado. C'alifornia pro- duced 6.8 per cent of the countrv's value of petroleum; 99.5 per cent of borax; 3.1 per cent of c(»pper ore; and 83.6 per cent (jf (juicksilver. Montana owes its rank as eighth among miiung states almost entirely to its enormous })roduction of copper ore, although the precious metals and bituminous coal, with outputs valued at$4. 688,536 and $2,443,447, respec- tively, contributed about one-fourth of the value of the state's mineral products. The output of copper ore, valued at $20,563,353, or 40.2 per cent of the total for this industry, formed 72. s pei- cent of the $2S.265.(lS5 reported as the total value of the state's mincnd ]iro- duction, afforded employment to 6,3SS wage-earners, or 60.6 per cent of thi' 10,539 mining wage-earnci-s, and ; paid them $7,339,773, or OiM pci- cent of the totid of $11,812,150 expended for wages. That Montana is pre- eminently a mining state is discernible at a glanc(» when it is noted that in populaticjn, agriculture, and maiuifac- tures it I'anked forty-third, thirty-seventh, anfl thirt\'- fourtli, i-espectively. Indiana, closely ]iressing Montana, raidxed ninth in the products of mines and (|uai'ries, a position which is the result of tlie \iilue of its fuel pi'dducls, its leading mini'i'al I'esdurei's being bituminous coal, nntui'al e-as, and jieti'dleiun. St I'lietural materials. ;is repri'sented by limestones and dolomites and cement, also contributed much to the state's mineral wealth. The five classes of products just mentioned show a value amounting to $28,159,545, which is 99. K per cent of the total for the state, $28,224,760. The total was distri))uted among the five as follows; Bituminous coal, $10,399,660, or 36.8 per cent; natural gas, $7,081,344, or 25.1 per cent; petroleum, $6,526,622, or 23.1 per cent; limestones and dolomites, $2,865,691, or 10.2 per cent; and cement, $1,286,228, or 4.6 per cent. Of the 16,473 wage-earners engaged in mining in Indiana, 10,593, or 64.3 per cent, were employed in extracting coal, receiving in wage.s $7,396,425, which is 68.9 per cent of the $10,729,767 paid in mining wages in the state. The .state ranked ninth in agriculture, while in population and manufac- tures it was eighth. Minnesota, nineteenth in population, eleventh in agri- culture, and thirteenth in manufactures, was tenth in mining. The total value of its mining production was $25,729,545. of which $23,989,227, or 93.2 per cent, was credited to iron ore. There were but 6 of the dif- ferent classes of minerals reported for the state, and none "except iron ore had an output valued at more than $l.ooo,0(.)o. Of the 9,760 wage-earners employed in the static's mines, 8.256, or 84.6 per cent, "were credited to the iron ore industry, receiving 84.1 per cent, or $5,376,933 of the $6,391,184 paid out as the total wages. In this industry INIinnesota was exceeded 1)3' Michigan only, contributing 36.6 per cent of the total value as compared with Michigan's 40.8 per cent. HirtcraJ j>r<>(lnrt>< hi/ ijiiKji-iiplne

III. LUriTATIONS OF THE USK OF CEN.'^U.S STATISTICS OF MININ(}. The uses that can propc^rly be made of the census figures are discussed in the reports on the diti'erent minerals, and also in diti'erent sections of this summary and analysis. The limitations imposed are similar to those which appear in connection with the use of the statistic's of manufactures di.scussed in detail in Part I of the report on manufactures of the Twelfth Census. The statistics of mines, quarries, and petroleum and natural-o-as wells can he accepted as indicating the growth and relative importance of th(.» states, and of the different sections of the country in the production of the diti'erent minerals. When possilile the figures have been presented in comparative tallies which em- brace data reported at pre\-ious censuses. The figures can be used to ascertain the (juantity and the value of the different minerals produced, the average numlierof persons employed in their pi'oduction. and the total amount paid in wages in the different states at different census periods. The general condition of the mining industries of the country and the extent to which the mineral deposits in the different states have been de- veloped can likewise be determined. The limitations of the use of these statistics may be summarized as follows: 1. The figures show only the total production for a period of twelve months. They do not indicate the char-' acter or extent of the mineral deposits or the proportion of these deposits that remains to be mined, nor the pos- sible or relative advantages to be deri\'ed from mining in diti'erent sections of the country. 2. The exact relation l)etween cost of mining ;ind value of products can not Ijc determined from the sta- tistics. The Census inquiry was designed to obtain a complete statement of the more important items which niak:c up the cost of mining, but there still remain many items of expense of which it was impossible to obtain a record. For this and other reasons the Census figures throw no light whatever upon the profits of mining, or upon the relative shares of the product which go to capital and labor, respectively. The items of expense which are presented separately in the Census reports are summarized in the following stfifement: 58 MINES AND (JUARRIKS. Value of products 8790, S'iii, 417 Cost of supplies and materials 1^123,811,9(17 Salaries, wages, and contract work t29, fi5s, 4,50 Miscellaneous expenses 71,771,713 Total cost la.i, 24."), 130 Excess of value of products fiver total cost *171,.s,si,2,s7 Such a calculation would make it appear that the profit of mining- was about |1T(I,00(),000, but .such a conclusion is unwarranted and improper. The tigures take no cognizance of the depreciation of the plant, of expenses incident to the sale of the product, or of interest on capital invested; they ignore the element of loss due to bad debts and the element of risk and speculation incident to marketing the products. The value of the product reported to the Census is the value at the mine or quarry. It was beyond the scope of this investigation to follow the product further. The Bureau of the Census made no inquiry concerning the capital, accounts current, or assets of the mine opera- tors, and it was impossible to determine from the sched- ules received whether the business had been conducted at a profit or at a joss during the year covered by the report. .3. The average earnings of employees can not be deter- mined from these statistics. The reasons why this is not possible are given on page 95, where the statistics for employees and wages are discussed. ■i. The Census tigures can not be used to determine the respective shares of capital and of labor in the results of mining operations. The amount of money reported as paid out during the year in the form of wages can be taken as the contribution which the mining opera- tors returned to the wage-earning class from the results of operations carried on, but what relation this sum bears to the interest earned on the total capital invested or to the total profits of mining it is impossible to estimate. Such relations can bi_' determined only liy special investigations of typical mines in selected lines of production. IV. NUMBER OF MINES, QfARlilES, AM) WEI.LS. A consideration of primary impoi'tance in any census investigatifin is the selection and proper definition of a suitalile unit of enumeration. Generally the unit chosen is one that is sanctioned by common experience, as the individual in the enumeration of the population, the farm in agriculture, the establishment in manu- factures, and the mine in mines and mining. As defined by the mining laws of the I'nited States the word "'mine"' applies tf) a single mining claim or a single shaft or other opening, and the term has been used in this sense \vhene\'er such a claim was mined s('parately. In tlie ease of many mining properties, however — particulai'ly those tliat wei'e at an advanced stage of flevelopment — it was found that th(! ])i'operty had erown bevoml the ]iiiiind;Lr\- of one claim anrl included contiguous claims that frequently were con- nected with the original claim ))y underground tunnels and workings, and were so closely associated with it in their operations that even the owner or lessee could not segregate the operations of the different claims. The Bureau of the Census has designated as a mine, any claim or group of contiguous claims operated as a single property. In certain cases, however— as in that of the larger coal companies operating in the anthracite region of Penn.sylvania— it was found impracticable to secure .separate reports for collieries in the .same county, even when noncontiguous, and in such instances, the reports were frequently made on a single schedule. On the other hand, in case of a mine worked by several lessees, each of whom operated independently, separate reports were often made, but whenever possilile a single report of the operations was secured from the lessor, or the reports of the several lessees were con- solidated. The operation of mines by lessees is a condi- tion fre([uently found in the mining of precious metals and in the zinc mining region of southwestern Missouri. A single oil or gas well tmder individual management or a number of contiguous wells under the same man- agement were considered, for census purposes, as a single mine, but each well was also enumerated and countetl in the tables as a separate unit. In the produc- tion of some minerals, such as precious stones, placer gold from small placer deposits, and monazite, mining in many instances ^^-as not carried on continuously at the same locality, and it was impossiljle to ascertain the number of distinct mining operations. The term "operator"" represents the individual, company, or cor- poration that controls the mine. The distinct mining operations under the control of the ,same operator and located in the same county were included in one report to the Bureau of the Census, or in .separate reports, to suit the convenience of the operator, l)ut if the distinct operations were situated in different counties a separate report was made for each county. At the census of 1880 the term ''estalMishment of industry" was vised in compiling the statistics of the mining industry. In defining this term it was said that "the term 'establishment of industry,' as used in these tables, may be taken to mean a mining operation the accounts of which are separate, and the product of which is not mingled with that of any other before it is shipped, though at the same time it may consist of numerous distinct mine openings.""' This definition is in general, consistent with that adopted in this report, but certain important exceptions have been noted. In the fiiddwork of thi' present investigation special agents wi're instructed as follows: "It is important that a separate return be made for each mine or quarry, and that the statistics of employees, \\ages, expenses, and supplies entered on the schedule pei'tain only to 'Tenth Census, Vol. XV, liei>ort on Miniiii; Iiidnstrii's, pafje X X i V . SUMMARY AND ANALYSIS OF RESULTS. 59 the mine oi' quarry reported. This rule ishould he olv served in all hranches of niiniu".;- and ([uarrving except petroleum and natural-gas wells, where all the wells located in a certain g-roup or conducted under one own- ershi]> should he reported upon the .same schedule. However, if more than one mine or ([uarry in the same county is owned hy the same company or lirni, and it is impracticable to make a separate report for each, a combined report may be made which will include the operation.s of all. Mines or quarries, under the same ownership in diiferent counties, must be reported on separate schedules. If a schedule includes the opera- tions of more than one mine or (juarry, a memorandum, giving the name and post office address of each mine or quarry inchided. should be attached to the schedule." Sometimes it was impossible to state the number of mines reporting; this was the case with precious stones which, as a rule, are not obtained from regularly operated mines but through occasional hndings or through systematic search. In such cases there is no mine, and the number of opei'ators only is shown. It was also impracticable to ascertain the numl>er of sepa- rate mines for gold and silver, and copper, and the number given is the number of operators. This prac- tice was also followed in lead and zinc. In order to comply with the requirements of the law the canvass covered all mines and quarries, both large and small, and thei-efore included not only the commer- cial mines but also those worked to supply a local demand, such as the limestone f|uarry operated by a farmer to secure material for his own con.sumption or to furnish lime for the use of the immediate neighbor- hood, and the small, irregularly worked, bituminous coal mines. This practice has resulted in the inclusion of the large, fulh^ equipped mining plants and the small stone quarries worked at irregular intervals. The large and small mines are given equal weight in ascer- taining the number of mines and the number of opera- tors. It is evident, therefore, that the unit, '"a mine," is ambiguous and does not always signify the same thing. A thorough enumeration of the small mines or quarries worked to supply a product for local consumption is not essential to a mining census. Thej' are incidental to the canvass, and special efl'ort should be made to enumerate them only when they are characteristic of a locality or mineral. For instance, the enumeration of the small lead miners of Missouri or of the small Ijituminous coal operators of Kentucky is important, but, as explained on page 18, it is impossible to eiuunerate all of the small placer gold miners and their omission makes no appre- ciable difference in the aggregates. This is especiallv true when the total production of the metal can be obtained from other and more reliable sources. The increase in the number of mines reported at different censuses is not necessarily an indication of an incrciifse in the mining industry as a whole. The small operators might be especially active during the vear of the canvass, while a number of the large mines might be idle or working on part time. Under such condi- tions the reports would show a lai'ger numbei- of mines but fewer wage-earners, less wages, and a smaller product than would be the case if the conditions were i-eversed. This is illustrated b}^ the statistics for coal mining. There were 12,552 coal mines reported at the Ele\'enth C'ensus, with 294, -±15 ^v age-earners, and a product valued at 1160,226,323. In 1902 the number of mines reported decreased to 5,986, while the immber of wage-earners increased to 350,329 and the value of the pi-oduct, to $367,032,069. No figures at previous censuses are available for a satisfactory comparison of the number of mines for all minerals, but the following statement sho^s the number of producing mines reported for some of the most important minerals at the censuses of 1902 and 1889: Xuiiibi'i- of pi'oducing iiniiea for pvincipal minerals: 1902 ond 1889.

The above statement indicates that there were more mines engaged in the production of iron, anthracite coal, and the precious metals in 1889 than there were in 1902, and this is probably true for iron and coal. Notwithstanding this apparent decrease in the number of mines, there has been a large increase in the amount and value of the products for all the minerals enumerated. "When, as is frequently the case, more than one variety of mineral is obtained from the same mine, it is impossible to give the num- ber of mines producing each variety, and then present totals, without some duplication. This duplication was avoided at the present census by classifying the reports act'ording to the mineral of chief value and counting- each mine as a single unit, irrespective of the number of distinct minerals obtained from it. The mines reported for each classification have been arranged in three groups: (1) Active mines reporting production; (2) active mines reporting no production, the work being confined to development, exploitation, or care of the property; (3) mines that were idle during the entire year. The number of these different classes of mines reported for each classification of minerals is shown ill Table lo. 60 MINES AND QUARRIES.

Lar(ji' and simtll iijhriiforK. — These averages jier op- erator are a general indication of the magnitude of the individual e.stablishments for the entire country, but the large number of small operators incduded in the total tends to reduce the size of the average establish- ment without an increase in the total jjroduction corre- sponding to the number of operators employed. For instance, the average operator in anthracite coal gave employment to 5S00, whereas the average numberof wage-earners enif)loyed per opei'atoi' f(jr tliis minei'al is only Isl. In the production of iron ore a single operator reported the employment of -1,66-1: wage-earners for the busiest month and paid more than $3,600,000 in wages, the \-alue of his animal product amounting to over $11,700,000. The average operator in the prcjduction of precious metals ga\'e employment to only 13 wage-earners dui'- iiig the year, liut the operator most largely engaged in the production of these minerals gave employment to 3,030 wage-earners during the busiest month of the year, paid in annual wages over $3,3(»:-),.S;")l, and had a product valued at the mine at more than $1:, 300, 000. When petroleum and natural gas are left out of con- sideration, the largest operatoi' was reported for Ititu- minous coal. This estalilisliment gave employment to 15,639 wage-earners on the average during the year, paid more than $8,S00,O00 in wages, and had a product amounting to o\-er $13,OOO,0o0. The following table groups the operators according to the values of their products, and thus indicates the proportions of the total product ol)tained l)y large and small operatoi's. The reports for petroleum and natural-gas companies have been excluded from this table, and'the value of the by-products, referred to on page 25, have ))een reassigned to the total for the mineral fx'om which they were obtained.

They constituted only 31 per cent of the total number of operators, but their products formed 96.9 per cent of the total value of products. In other words, less than one-third of the operators produced more than nine-tenths of the mining products of the country, exclusive of petro- leum and natural gas. The concentration of production is more pronounced in some of the minerals than in others. For instance, of the total for metallic sub- stances, 3.9 per cent of the operators produced 72.7 per cent of the product; in coal mining, 5.2 per cent of the operators produced 65.4 per cent of the product: in structural materials, 25.2 per cent of the operators pro- duced 91.3 per cent of the product; in abrasive materials, 18.7 per cent of the operators produced 73.2 per cent of the product; and in the production of all other sub- stances, 29.1 per cent of the operators produced 8S.2 per cent of the product. The taV)le shows for each group of minerals a marked decrease in the percentage of operators in the higher value groups, accompanied by a corresponding increase in the proportion which their products formed of the total for all producers. It has been the practice at previous censuses to omit from the tabulation the reports for all establishments showing iin annual product valued at less than $5t»0. If this practice had been followed at the mining census of 1902, there would have been omitted from the total 5,345 operators, or 29.8 per cent of all opei'ators, their product being valued at $916,214, or one-tenth of 1 per cent of the total value of all products. These figures are exclusive of the reported values of product for several small operators connected with the Standard Oil Company, whose products, which were less than S500 each in value, are included in the returns made l>y that company. The omission, therefore, of the small oper- ators would have but slight effect upon the statistics of production and labor. The conditions in the mining industiy dilfer radically from those in manufactures. The omission of the establishments with a product of less than $500 is made in the statistics of manufactures so as to avoid the necessitv of securing and tabulating returns for small shops in which no one is employed except the owner, who niay also be engaged in doing odd jobs, and would thus be more properly classed as a mechanic than as an independent manufacturer. This explanation would not apply to the statistics for mines and quarries. Many mines are operated only a part of the year, and the limited production is due to the short time of oper- ation rather than to the size of the mine or to the extent of the deposits. As explained on page 20, 7 returns were received from the Standard Oil Company relating to the pro- duction of petroleum and 4 relating to the production of natural gas. These schedules covered the work of 28.925 oil operators and 19 gas operators. As only 1 combined report was made for a large numlier of the operators, it is impossible to segregate the production of the operators so as to assign them to the different groups according to their production. The statistics of natural gas and petroleum are presented in Tables 19 and 20, the Standard Oil Company being considered as a single producer of both natural gas and petroleum. <«4 MINES AND gUARRIES.

This is indicated hy the value of product, which amounted to $4i:,-l:6:^,756 in the case of individu- als, and formed only (i.l percent of the total for all mines. Comparatively few individual operators (•(in- ducted enterprises of great magnitude, lint in the pro- duction of 13 difl'erent classes of minerals, enumerated in Table 31, the product reported for individual ojjer- ators exceeded that of firm.s or partnerships. In no case, however, did the value of the products of indi- viduals exceed the value of the products of incorporated companies. Firiiif! ill' jmrtnei'shlps. — In many instances these forms of ownership are l>ut a step to the formation of incorporated companies. They include all firms and partnerships, whether general or limited. The 3,718 firms or partnerships formed 21.5 per cent of the total number of operators, and their products were valued at §52,782,1-1:3, or 7.3 per cent of the total value of prod- ucts. The number of firms or partnerships was not as great as the number of individuals, but the value of their products exceeded the value of the pi'oducts of individuals by $8,319,387, or 18.7 per cent. The pr(xl- uct under the firm or partnership form of ownership exceeded the product under incorporated companies in the cases of manganese ore, barytes, and mica. No firms or partnerships were reported as engaged in the pro- , duction of borax, bauxite, fuller's earth, tungsten, or uranium and vanadium. lucorpornted companu-s. — From the standpoint (if value of products the incorporated form of ownership now predominates in both manufactui'es and mining, but especially in mining. According to the reports of the census of 190*» the value of the products of incor- porated companies engaged in manufactures formed 59.5 per cent of the total gross value of products of all manufactures. In the mining industry the products of the incorporated companies formed 86.3 per cent of the total for all mines and quarries. This form of owner- ,ship includes all joint stock companies, the capitaliza- tion of which is usually divided into shares of a fixed authorized \'alue, transferable at the option of the indi- vidual shareholders. These companies are usuall}' in- corporated undei- the general corporation laws of the diti'ei'ent states, but in a numljer of instances the cliai'- ters are obtained by a special act of the legislature. The predominating iujportance of thecorporati(jn in the production of the difl'erent classes of minerals is shown by Table 22. This form of ownership was reported for all of the minerals, with the exception of bLihrstones and millstones, lithium (jre, tungsten, and uranium and vanadium, and in all, with the exception of manganese ore, barytes, mica, slate, and '"all r minerals,' the value of the products of the incorporated companies was far in excess of that shown for the other forms of owner- ship. In the majority of cases it was more than double the value of products reported f(jr either individuals or firms. The great increase in the consumption of coal and the demand for raw material to meet the ret(uirements of manufactures has resulted in a general and extensive development of the mining industries, especial!}- those for which the deposits are confined to well-defined geo- graphic districts. Extensive mining operations can be carried on successfully only by the employment of large capital, and the incorporated form of ownership is the most convenient method of raising such capital. Incor- porated companies organized primarilj' for manufac- turing enterprises frequently engage in mining in order to control the supjdy of raw material and to enable themselves to practice economy in production. The production of borax, molj'bdenmn, and rutile was con- trolled entirely by incorporated companies during the ! census year. ' The incorporated form of ownership in all branches of nunerals is of such overwhelming importance that the statistics for employees, salaries, wages, expenses, and products for such companies are of great impor- tance when compared with similar statistics for all other forms of ownership. The following table makes a com- parison of this character for each class and for the difl'erent groups of minerals: 68 MINES AND QUARRIES.

(ils, oi- sn per cent of the wag-e-earners, and paid .$8()6,3ti9,(;i!2, or 85.9 per cent of the total wages paid liy all operators. These companies also paid $49,707,399, or 8S.9 per cent of the miscellaneous expenses, and the cost of their supplies and materials reached $93,115,790, or 87.8 per cent of the total cost, while the value of their products, amounting to 1626,132,335, was 86.3 per cent of the value of products for all mines, quarries, and wells. Incorporated companies have assumed the greatest importance in the production of ores. They employed 98,837, or 89.5 per cent of the wage-earners in the metallic group and paid them $74,888,135, or 89.1 per cent of the wages. The products were valued at $192,297,393, forming 89.3 per cent of the total value of products in this group. Practically the entire production of copper ore was under the control of incorporated companies, these companies emploj-ing 97.9 per cent of the wage-earners and reporting 98.5 per cent of the total value of prod- ucts for this mineral. Onl}' 144 operators were I'eported for this mineral and but 44 of them were unincorporated, their product forming only 1.5 per cent of the total value of the product. In the metallic group of min- erals iron ore stands next to copjDer in the part played bj' incorporated companies, this form of ownership giv- ing employment to 36,316, or 93.5 per cent of the wage-earners and reported products valued at 96.7 per cent of the total value of products for this mineral. The large number of small ojjerators engaged in the production of lead and zinc ore in Missouri and in the production of precious metals throughout the Western states reduced the comparative importance of incorpo- rated companies in the production of these minerals. Manganese ore was the only exception to the predomi- nance of the corporation in the production of ores. The production of this mineral is still largely under the control of individuals and firms. Next in importance to the ores, in the production by the incorporated form of ownership is the group of minerals classed as fuels. In the foregoing table the statistics for fuels do not include the production of petroleum. Of the 6,477 operators reported for an- thracite and bituminous coal mines and natural-gas wells, only 2,226, or 34.4 per cent, were incorporated companies. These companies, however, gave employ- ment to 317,121, or 89.3 per cent, of the 355,007 wage- earners, and their products, valued at $356,399,452, formed 89.6 per cent of the total value of products for this mineral. In tliis group the pi-edominance of the incorpoi'ated form of owncrsljj]) was especially pi'o- nounced in the ])ro(luetiun of natural gas, the iiicoi'- porated companies employing 96.7 per cent of the total lunnber of wage-earners, and producing 95.7 per cent of the total products. In the production of anthracite coal, 76 incorporated companies, forming 63.9 per cent of the operators, employed 63,317, or 90.9 per cent, of the wage-earners, and their products, valued at $69,209,224, formed 90.9 per cent of the total value of the products of the industr}-. The 1,517 incorpo- rated companies engaged in the mining of bituminous cOal gave employment to 249,280, or 88.8 per cent, of the wage-earners, and the value of their products, amounting to $257,639,338, formed 88. 6 per cent of the total value of bituminous coal mined during the vear. Of the 5,746 operators reported for structui-al mate- rials, 879, or only 15. 3 per cent, were incorporated companies. This comparatively small proportion of incorporated operators controlled considerably more than half of the industry. Their wage-earners, num- bei'ing 53,589, formed 62.1 per cent of all wage-earners, and their products, valued at $64,208,623, formed 66.6 per cent of the products. Of the different classes of minerals included in this group the incorporated form of ownership predominated for cement, limestones and dolomites, and marble. The manufacture of cement reported by the Census was confined to establishments operating quarries. Practicalh' the entire output obtained in this manner was produced b_v incorporated companies. These companies gave employment to 98.6 per cent of the wage-earners engaged in the industry, and their production formed 99.3 per cent of the value of the products. Only 10 of the 93 operators were unincorporated, and their production formed onlv se\'en- tenths of 1 per cent of the total value of the product for the industry. The incorporated companies engaged in the produc- tion of limestones and dolomites ga\'e employment to 59.5 per cent of the wage-earners reported for all (.[uarries devoted to the production of these stones, and in value their products formed 59.8 per cent of the total. A greater 2:)reponderance of the incorpo- rated form of ownership is shown for marble, the incorporated companies in this industry employing 87.1 per cent of the wage-earners, and reporting 88.6 per cent of the total A-alue of products. The i^roduction of clay reported by the BLu-eau of the Census was confined to the products sold as such, and did not include the manufacture of Ijrick and potterj' products. While the number of wage-earners and the value of the product reported for the unin- corporated operators engaged in clay mining and in the quarrying of sandstones and quartzites, siliceous crystalline rocks, and slate, were slightly in excess of those reported for incorporated companies, the indica- 72 MINES AND QLIARKIKS. tions are that the incorporated foriii of ownership is assuming control of these industries. The mines engaged in the production of abrasive ma- terials and controlled by incorporated companies gave emplo3'nient to 60.5 per cent of the wage-earners re- ported for this group, and their products formed 75.6 per cent of the total value. Only ii9 quarries were re- ported as engaged in the production of ))uhrstones and millstones as their principal products. Twentj'-three of these quarries were operated under the individual form of ownership and 6 by tirms or partnerships. The larger proportion of buhrstones and millstones was ob- tained from sandstone quarries, which are includeil under the group of structural materials. The figures in Table 23, therefore, do not indicate the proportion of the products of this class obtained from (juarries operated by incorj^orated companies. The incorporated form of ownership predominated in all of the other minerals included in the g roup of abrasive materials with the exception of garnet. In the case of garnet 3 of the 7 operators were incorporated, and th(>v reported a pro- duct valued at S27,900, or 21 per cent of the total for this mineral. The production of chemical materials shows a decided preponderance in favor of the incorporated form of owneiship, over 78 per cent of the production of each mineral being reported by incorporated companies. Taking this grou]i as a whole, the corporations — 116 out of the 174 producers --employed S4.7per cent of the wage-earners, paid 85.2 per cent of the wages, and re- ported 88.3 per cent of the total value of the product. Of the 77 producers of pigments, 28 were incorporated. These incorporated com anies emploj^ed 286, or 48.3 per cent, of the 592 wage-earners, and paid SI09,48<», or 46.3 per cent, of the wages, and their products amounted to $371,651, or 65.9 per cent, of the total for the group. The miscellaneous group of minerals, taken as a whole, shows that the business of incorporated oper- ators predominated in the proportion of about 3 to 1. They constituted 15.1 per cent of the 68iS producei's, employed 79.5 per cent of the 2,433 wage-earners, paid 78.6 per cent of the $1,035,784 paid in wages, and reported a product valued at $2,592,192, or 77.5 per cent, of the total for the group. Petroleum. — As previously explained, the character of ownership was not reported for 28,924 operators engaged in the production of petroleum, and for this reason the data were excluded from the preceding- tables. In the following tal)]e the report for the Standai'fl Oil Company has been considered as that of an incorporated company covering the operations of 28,924 other (jperators. While this rearrangement does not show the true character of the ownership of the indi\-idual operators, it pi-ol)ably conveys an accui'ate idea of the actual control of the production.

Iiidiixfriiil cinithiaiitloiia. — The statistics presented in the preceding section indicate the extent to which the firm and the incorporated company ha\-e assumed control of the mining industries. The exigencies of production on a large scale and the desirability of con- ti'olling all or a large portion of the deposits of certain minerals, combined with the advantages of carrying on mining and manufacturing under the same management and with the use of the same capital, have led to the con- solidatic)n of formerly independent operators and the formation of what are commonly known as indu.strial combinations. Such combinations are a form of in- corporated ownership, and the statistics for them should lie considered in connection with those for incorporated companies. This form of owii(>rship has assumed large proportions in the manufacturing industries. In pre- senting tlie statistics of combinations in these industries the following detinition was given in the report of the Twelfth Census on manufactures: For the puriiosie of the Cennus tlie rule haw been adopted to con- sider no ai;grenation of Jiiills an industrial eondiination unless it (■(insists (if a number of formerly independent mills which have been brought together into one company under a charter obtained for that purpose. We therefore exclude from this catetrorv many large establishments comprising a number of mills whidi have grown up, not by c(jndiinatioii with other mills, but by the erec- tion (if new plants cir the purchase of old ones. The word "trust" was avoided in this definition, because, while it may hax e come to convey to the popular mind a definite idea, it stands technically for a form of organization under which the stockholders of each of the separate companies a.ssign their stock to a certain luimber oi trustees, thus giving t(j these trustees an irrevocalile power of attorney to vote the stock as they see fit. This form of organization has been declared illegal by tlie act of .July L', bSHd, Fifty-first Congress, first session, entitled " .\n act to protect trade and commerce against unlawful restraint of monopolies" (L'(i Statutes at Large, page 20i1), and by the statutes of many states. SUMMARY AND ANALYSIS OF RESULTS. 73 While tlie compilation of stati.^tics for iiiiuiufactiircs in conformity with this definition resulted in the \m-- sentation of totals which show the extent to which formerly independent establishments have come under the same ownership, and the magnitude of their opera- tions, they do not show the extent to which th(> production has become concentrated in fewer establish- ments. In order to show such concentration it is necessary to consider all large establishments, irrespec- tive of the method of their formation, and this lias been done for the mining industries in Sections V and VI of Chapter II. As the extent of the deposits of many minerals can be determined very accurately and the production controlled thi-ough their purchase, the min- ing industries hold out iiiducciU(Mits which do not exist in other industries to the formation of industrial com- binations or other forms of business organizations to control the production. The operations of a number of corporations in the mining industry have acquired enormous proportions through the gradual purchase and development of new properties, and there are numerous cases of consolida- tion of small independent operators, especially in the production of gold, silver, lead, and zinc. AA'hile the object of these consolidations may sometimes be the reduction of operating expenses, such consolidations are frequently made with the intention of issuing a larger amount of capital stock than was possible under an independent form of organization. In many instances indei^endent mining claims or prospects have been made the basis for the organization of corporations, and the claims have been capitalized on their possible produc- tion, although mining operations had not actually com- menced at the time of the formation of the company. The production of some minerals is probal)h' con- trolled b_v a mutual undei'standing between the operators of the mines or between the operators and transporta- tion companies, but it is impracticalile to identify operations which are controlled by arrangements of this character. A number of the companies included in the mining census were engaged in other industries, such as manu- factui'ing or transportation; the mining operations were incidental to their other interests, and it was impossible to segi'cgate the capitalization so as to assign a pi'oper proportion to the mining inteix'sts. The Standard Oil Company, for example, is engaged primarily in the refining of pctrolemn and produces ordy a linnted amount of crude material; but, as explained on page 20, this company made reports covering the operations of a large luunber of producers f)f petroleum. The Cnited States Steel (Jorporation is engaged primarily in the manufacture of iron and steel products, )iut it also oper- ates a number of iron ore and coal mines, linjestone (|uarries, and natural gas wells, and its capitalization covers other interests. A ruimbei' of large companies which are engaged extensively in manufacturing, as well as in mining and othei' industries, have repoiled their entire c;ipitalization in I'eply to the inquiries on the mining schedule, together with all dividends and interest accrued from the profits of Ijoth the mining and manufacturing operations, declaring that it was impossi- ble to make a separation. Notable among such com- panies are the Kepu])lic Iron and Steel Company, the Sloss-Shetfield Steel and Iron Company, the New Jersej^ Zinc Company, the Alal;)ama Consolidated Coal and Iron Company, the Colorado Fuel and Iron Company, the Empire Steel and Iron Company, the Pacific Coast Company, the Philadelphia Company, the Tennessee Coal, Iron, and Railroad Company, and the Virginia Iron, Coal, and Coke Company. This is also true, to a greater or less degree, of most of the companies reporting capital stock, as a '/eiy small proportion of them confine thcfir operations solely to mining. It is evident, therefore, that while industrial combi- nations similai' to those referred to in the report on manufactures of the Twelfth Census do exist in the mining industries, it is impracticable to compile satis- factory statistics for them. But eliminating from consideration the production of coal, petroleum, and natural gas, and compiling the statistics of the rest of the minerals in as close conformity as possible with the definition given above, it is found that industrial com- binations exist in the production of several minerals. Table 26 shows for all the items discussed in this chapter the totals for all operators and for industrial combina- tions in the same minerals and the percentages that the industrial coml)inations are of the totals for all operators. 74 MINES AND QUARRIES.

All of the objections to the statistics for capital in manufactures apply with greater force to the statistics for mines and quarries, and tiiey ma_v be summarized as foUow's: 1. It is impcssihle to define the word " capital " for .statistical measurement so that it shall be tangible, restricted, and uniform. ii. The inquiry creates more prejudice and arouses more opposition to the progress of the enumeration than all of the other inquiries united. 'A. The value of " lixed capital " — land and buildings — is dependent upon conditions of which a census can take no cognizance. 4. The difficulties attending the collection of statistics for live capital— "cash on liand, bills receivable, unset- tled accounts, etc." — preclude the possibility of reliable results. 5. It is impossible to eliminate the duplication in gross assets and credit capital. 6. Good will, patents, mining rights, etc. , are forms of capital for which no satisfactory value can ))e obtained. 7. Many mining companies have investments other than of the amounts required to carry on their business The operators classed as industrial combinations and engaged in the production of iron ore gave employ- ment to 49.3 per cent of the wage-earners and in value their products formed 58.3 per cent of the total value of all the iron ore produced during the year. While onl}' 14.6 per cent of the operators of copper mines were classed as industrial combinations, they gave employ- ment to 43.5 per cent of the wage-earners and their products formed 55.7 per cent of the total value of products. VII, CAPITAL. Reasons for not securing statistics. — It has been the practice at prior censuses to include in the report on mining industries statistics concerning capital invested. The object was to ascertain the value of all mining properties and money invested or used in the business, whether owned or borrowed. In prder to develop these amounts the inquiries called for the value of the mine and improvements, including land, buildings, fix- tures, tools, implements, live stock, machinery, etc., and were in harmony with those concerning capital in- cluded in the schedule for the manufacturing and me- , was the first census law that specified the character of the inquiries to be embraced in the schedule for manufactures, and the ''amount of capital invested" formed one of these inquiries. The same law provided for the census of mines, mining, and minerals, but in enumerating the different sul)jects to be included in the report, no reference was made to the capital invested. The absence of a definite provision of law and the unsatis- factory character of the statistics concerning capital collected at prior censuses, justified the omission of this inquiry from the mining census of 1902. The report for this census, therefore, contains no information con- cerning the value of the mining property or the actual amount of capital invested in the industry. Ccqyitalizntlon of incorporated compan/i's, l>y min- eralx. — Exclusive of the products of natural-gas and petroleum wells, 85.9 per cent of the mining products of the countrj^ during 1902 was produced by incorpo- rated companies, and the prevalence of this form of ownership indicates the desirability of collecting sta- tistics concerning their capitalization. While the capi- talization of incorporated companies is not the true value of mining properties, nevertheless, the companies are in position to gi\e the amount of capital stock :md bonded indebtedness, and inquiries concerning such values can y>e answered readily. The census schedule, therefore, contained the following inquiries: ing on the business. This statement, to be complete, should in- clude as capital " all money borrowed, as well as accounts having a long time to run. The idea is to get returned as capital all money invested and used in the l)usiness, whether owned by the party making the return, or borrowed. The value of land, tix- ture.s, etc., should be estimated at what they are worth or would cost in 1890." The inquiry for the j^recious metals called for sep- arate amounts, as follows: Total ji resent actual cash value ofiiiine and mining i)lant, % , to t)e distributed as follows: Present actual cash value of buildings at mine, 8 ; jiresent actual cash value of railroads on surface, S ; present actual cash value of machinery of all kinds above and below ground, includ- ing jjumps, engines, boilers, cars, tools, etc., % ; present actual cash value of underground improvements, including shafts, tun- nels, drifts, tramways, etc., % ; present actual cash value of mine supplies of all kinds on hand i)ecember 31, 1889, S ; present actual cash value of the mine itself, exclasive of the above items, I ; cash not reported in the foregoing items, $ ; '2.

For instance, if an iron companj' owned and operated a coal and an iron mine, the probabilities are that its total cayjitaliza- tion was reported, it being impossible to segregate the amount represented b3' each mining operation. It is probable that mining was the primary object of tlie formation of the majority of the companies, but in some cases mining was subservient to other interests, and, in a few instances, where the mining formed onlj- a small proportion of the interests of the corporation,- no capi- tal stock was reported. The Pittsburg Plate Glass Company and the American Sewer Pipe Compariy are corporations of this character. The totals, therefore, can not be accepted as the capitalization of mining en- terprises exclusively, nor can the dividends paid be accepted as the restdt of mining operations only. Exclusive of those engaged in the production of natural gas and petroleum, there were 4,318 incorpo- rated companies reported as engaged in the mining industries. Of this number, 1,01:5 answered the value of mill, smelting, or other reduction works, exclusive of mining property; piresent actual cash value of buildings, S ; present actual cash value of machinery and plant of all kinds ex- cept buildings, $ ; present actual cash value of supplies on hand December .31, 1889, S . In addition to these incjuiries a circular letter issued to the enumerators on JNIay 26, 1890, in- structed them that the total actual ^-alue of the entire mining plant at the close of 1889 should be given without regard to the capitalization of the corporation or firm. If the land was (iwned in fee or in mineral rights, the number of acres attached ti p the col- lieries and under development, together with its actual value, should be stated. In the case of leased land, it should be practi- cable for the lessee to give the value per acre of the tract under development, and an effort should be made by the enumerator to obtain this data either frcjm the lessee, lessor, or other reliable authority. If several collieries were drawing coal from the same bank, the value of the acreage for the same tract should be treated on one schedule and omitted from the others. 76 MIXES AND (;>UARRIES. inquiries concerning capitalization. A ]aiji;e propor- tion of the production of petroleum in Pennsylvania, New York, Ohio, Indiana, and West Viri;inia, and also a considerable amount of the natural gas produced in these states, was covered in the report of the Standard Oil Company. In answering these inquiries this com- pany gave an estimate of the capital stock and l)onds it considered devoted to production, eliminating, as far as possible, the stock incident to the refining and to enterprises not directly connected with production of crude petroleum. The company also reported its inability to give the number of incorporated companies whose production of petroleum bought by it was included in its schedules; therefore the number of incorporated companies given in Table 26 for petroleum can not be accepted as the actual number engaged in its. production. This table presents the statistics of cap- italization for all incorporated companies for each, mineral and group of minerals. 78 MINES AND QITARRIKS.

The 363 companies that reported the payment of interest on bonds were authorized to issue bonds to the value of $281,115,418. The amount actually issued and on which interest was paid formed 91.5 per cent of the total authorized bonded debt. Xittiirid ijan (tnd pil roleuhi. — As explained on page 76, the capitalization reported for natural gas and petroleum should be considered separately from that of other minerals. Table 33 shows that the total authorized capitalization of the companies engaged in the production of these substances amounted to $540,723,162, of which $442,540,596 had been issued. This includes the capitalization reported by the Stand- ard Oil Company. A total of $17,054,705 is reported as having been paid in dividends and interest on bonds, representing a return of 3.8 per cent on the capitalization (stock and l)onds) issued. In Table 33 the capitalization shown as issued includes all stock and bonds irrespective of the pajanent of dividends and interest.

The par value of the capital stock and bonds issued by these companies amounted to $281,33.5,689, or 63.6 per cent of the total amount issued. The capitalization actually issued by companies paying either dividends or interest formed 87 per cent of their total authorized capitaliza- tion, and the dividends and interest paid by them repre- sented a return of 6.1 per cent on capital stock and bonds actually issued. Of the 248 companies there were 216 that reported the paj^ment of dividends on either common or pre- ferred stock. The par value of the authorized capital stock of these companies amounted to $22.5,767,930, or 41.8 per cent of the total authorized capital stock of all companies; and the par value of the stock issued amounted to $211,774,741, or 47.9 per cent of the total capital stock issued by all companies. The dividends that were paid on either or both of these classes of stock amounted to $15,715,970, or a return of 7.4 per cent on the stock issued by such companies. Capitalization of incorporated companief;, iy state-"! and tei^ritories. — As previously explained, the capital stock of incorporated companies represented their entire capi- talization. In some cases the companies operated mines in difl'erent states and were engaged in the production of difl'erent minei'als. For instance, a mining company engaged primarily in the production of iron ore may also operate a limestone quarry, and some of its enter- prises may be located in difl'erent states. It was im- practicable to segregate the capital stock so as to show the.amount devoted to each industiy in each state, there- fore the total capitalization was assigned to the mineral or state representing the interest of greatest value. With the exception of buhr.stones and millstones, lithium ore, tungsten, and uranium and vanadium, the produc- tion of all of the minerals for which separate statistics are shown was controlled to some extent by the cor- porate form of organization and incorporated companies were reported for every state and territory io which minerals were mined. Statistics concerning employees, wages, expenses, and production of incorporated com- panies are given in Table 23, page 68, but since in an unknown number of instances the capital stock repre- sented interests other than mining and since the capi- talization for some companies was not reported or, for the reasons explained above, was excluded from the statistics, a satisfactory comparison of capitalization and production is impracticable. The statistics for the capi- talization for all minerals in each statp and territory are presented in Table 35. MINES AND QUARRIES. Table SS.-CAPITALIZATIDN OF INCORPORATED STATE OR TERRITORY.

VIII. EMPLOYEES AND WAGES. The schedules used at the Twelfth Census for collect- ing statistics of emplo3'ees and wages contained several important inquiries not used at previous censuses. Thus in 1902 employees were segregated into general groups of occupations, to show the prevailing dail_y rates of paj' for each occupation and the average number em- ployed during each month of the jear; the number engaged in mining or quarrying who received pay ac- cording to the quantity of work done (namel}', the number of tons, cars, or yards mined) and the total amount paid for such work; the amount paid for con- tract work, such as tunneling, sinking of shafts, boring- test holes, etc., when done b}' independent contractors, and the number of men employed in such work; and, finally, the total number of days that the mines or quarries were in operation during the j'ear. No provision was made in the schedule for a separate report of female employees, either wage-earners or those receiving salaries. There is no doubt that among the salaried employees there were some female clerks, but so few as to be a negligible quantity and of no statis- tical importance, and none of them was engaged in the actual mining or quarrying. On the otlier hand the number of females engaged in the difj'erent branches of manufacturing is comparatively large and, therefore, of vital economic and sociologic importance. In the vai'ious tables in this report showing wage- eai'ners and wages comparisons have been made with the statistics of earlier censuses whenever they were availaltle; but because of the adoption of a radically different method of ascertaining the average number of wage-earners at this census any comparisons will be invalidated to a considerable degree. In the schedules for 1889 the inquirj' as to the numl)er of persons em- ployed asked for the number of foremen or overseers separately, but the inquirj- as to the amount of wages paid did not call for a separate statement as to the amount paid in wages to this class of employees. As a result, the statistics for labor and wages published in the Report on Mineral Industries at the Eleventh Census show sepai'ately the number of foremen and overseers, but not the amounts received by them, and in no case can the wages paid to this class of employees be separated. In the statistics for 1902, on the other hand, foremen and overseers, with their salaries, are included with superintendents, managers, survevors, etc., and not with wage-earners. Again, the schedule for 1889 called for a separate statement as to the amount paid for contrart work, but not for the number of persons employed on such work, 'This section and the sections following, Contract Mining and Quarrying and Contrart Work, were prepared by Mr. Joseph 1). Lewis, chief of the division of manufactures. though such emploj'ees were probably included in the total average number of wage-earners. In the schedule for 1889 the inquiry as to labor and wages is followed by this note: " In giving the number of men employed include those employed by contractors and subcontractors as well as by the company itself." In the corresponding inquiry of the schedule for 1902 the note of instruction reads as follows: "Amounts paid for contract work not done bj' employees hired directly, and the number employed in such work, must not be included in this inquiry, but should be reported in answer to inquiry 6." In inquiry 6 of the schedule for 1902 the amount paid for tunneling, shaft sinking, boring test holes, etc. , if not done bj' employees hired directly, and the average number of men employed on such work are asked for separatel}'. The greatest difference, however, between the statis- tics for the two censuses results from a radical change in the method of obtaining the average number of persons employed. In editing the schedules for 1902 the figures for the average number of employees were reduced to a 300-day basis whenever the schedule showed them to be the average number for a shorter period; when it was evident that the employees had worked more than 300 days, the average immber for the longer period was allowed to stand. The figures for 1902, therefore, show the average numlier of employees that would be required at continuous employment throughout the year to perform the work done, while the figures for 1889 represent the aveiage number emplo3'ed during the actual time that the several establishments con- cerned were in operation and not an average number for the whole year.'^ It is obvious that the method adopted in 1902 tends to produce a smaller average number than the method employed in 1889. This is illustrated in the statistics for several minerals as shown in this report. Thus, for example, the statistics for the production of marble, which show an increase in value of product between 1889 and 1902 of over $1,500,000, seem to show a decrease in the average number of wage-earners. Ex- cluding the number of foremen and overseers for both years, the figures are as follows: 1889, 1,275; 1902, l.oTo. But while the figures for 1902 represent the continuous employment of 1,070 men for 300 davs, the average luimber of days worked by the 4,275 wage- earners in 18.89, as the detailed statistics show, was only 255. Reduced to a 300-day basis, the average number of wage-earners for 1889 is found to be 3,618, thus showing that there has been a substantial increase during the decade. '' The difference between the two methods of computing the aver- age is practically the same as in the .statistics for manufactures of the Eleventh and Twelfth censuses and is fully explained in the Report on Manufactures for the Twelfth Census. (See Parti, pages cvi to cxi. ) The instructions for verifyingand correcting the num- ber of wage-earners reported for 1902 lire given in Appendix C. SUMMARY AND ANALYSIS OF RESULTS. 91 It should bo stated also that it is iiiipi'aciic.ilik' to make a comparison of the statistics of waoe-carnei's and wages at the two censuses for the entire mining- industry because the figures were not summarized for the earlier period. Employees, ly clmset^.T-'^ha following table summa- rizes the totals reported for l!»(i'2 in answer to that part of the inquiry which called for the average number of each class of salaried employees and wage-earners and the amounts paid them: Table 30. — Employees by clames: 1902.

Salaried ofEcials, clerks, etc., usually receive annual or monthly salaries and, as a rule, are employed through- out the entire year; consequently, for this class, in a great majority of cases, it was unnecessary to make the reduction to the average for the year. The employees shown in Table 36 may be arranged in two groups — first, the office force, which consisted of 15,727 general officers and clerks, receiving $16,145,829 as salaries, the number and salaries forming 2.5 and 3.9 per cent, respectively, of the totals for all employees; second, the emplo^^ees engaged in supervising and in the actual work of the mines and quarries, which include the superintendents, managers, foremen, sur- veyors, etc., as well as the mechanics, the miners and their helpers, and all other wage-earners. This class numbered 60-1,129, and their salaries and wages amounted to $392,.S34,683, forming 97.5 and 96.1 per cent, respec- tively, of the totals. The superintendents, managers, foremen, and survej'ors are cla.ssed as salaried officials though the distinction between foremen and miners is difficult to preserve, especiall}' when there is very little, if an}', difierence in their wages. Exclusive of the general officers and clerks, 237,043 emplo3'ees, or 38.3 per cent of the total number were engaged in operations above ground, and the salaries and wages paid for such work amounted to $141,752,946, or 34.7 per cent of the total. The employees reported as engaged below ground numbered 367,086, or 59.2 per cent, and their salaries and wages amounted to $251,081,737, or 61.4 per cent of the total. The sepa- ration of employees so as to show the numbers working above and below ground can not be accepted as exact, because the same employees niay, at different times, work in both places, and in some classes of mining the distinction between the two branches of work is not pre- served uniformly. From Table 1, pages 348 to 361, it appears that emplo3'ees working below ground were reported for the majority of the minerals; liut of the total number of such einplo^'ees 352,472, or all but 7,751, were emploj'ed in the mining of coal, iron, copper, gold and silver, and the salaries and wages the}' received amounted to $240,737,543, or all but $4,135,887 of the total salaries and wages paid for work below ground. The miners, miners' helpers, quarrymen, and .stone- cutters, who may be accepted as the employees engaged in the actual work of removing the ore or mineral, and dressing the stone at the quarry, numbered 343,166, or 59 per cent of the total number of wage-earners, and their wages amounted to $230,142,393, or 62.2 per cent of the total wages.

A very large proportion of this class, however, were common workmen or unskilled laliorcrs. For the in- dustry as a whole the percentages which the nuniliers of the different classes of wage-eai'nei's were of lh(> total iiuinK'cr are as follows: Engineers, 4. .5 per cent; tire- men.

So far as possil)lo the minerals in Talde 37 are ar- rauged in groups according to their cluiracter or the uses to Avhieh they are put. l^\)r the reason that there is, as a rule, a similarity in the conditions of mining the minerals in the same gi'oups, the statistics in each group are more comparable with each other than with those of different groups. A notable exception, how- ever, is found in the group of fuels, in which the statis- tics for natural gas and petroleum are not at all analo- gous to those for coal, and are not in any sense com- parable with them on account of the entirely diff'erent conditions governing production. The conditions that chiefly affect the proportions of the several classes of wage-earners are the methods of mining, whether surface or underground, and whether the mineral is sold in the crude state or undergoes some process of manufacture at the mine before being marketed. If the mine workings are underground and are spread over a wide area, the proportion of miners is reduced and those of other classes are correspondingly increased. Conversely, in surface mining and C[uarry- ing, the proportion of those engaged in the woi'k of get- ting out the mineral is, as a rule, larger than in the other branches. Any manufacturing process to which the product maj' be subjected at the mine or (juarry befoi'c shipment necessarily increases the proportion of "all other wage-earners.'' This is plainly indicated in the statistics for cement, the finished cement being in every case manufactured in connection with quarrying the rock, and also to a slightl}^ less degree in the case of gyp- sum, the work of manufacturing land plaster, wall or cement plaster, and plaster of Paris being done at the C|uarry. The j:)roportions of "all other wage-earners'' in these two industries were 58 and 51.2 per cent, re- spectively. The largest proportion in this miscellane- ous grcnip of employees, namely, 66.9 per cent, was for the natural gas industiy, in which the principal work, after the equipment of the property is complete, is the distribution of the gas to the consumers; and the group of "all other wage-earners" was composed chiefly of the various classes of employees engaged in this part of the work. In this industry the mechanical force composed of machinists, blacksmiths, carpenters, and other mechanics, formed 23 per cent of the entire num- ))er of wage-earners. Upon comparing the statistics for petroleum with those for natural gas. it is found that the percentages for the mechanical force were almost identical in the two industries, but that in the petroleum industry the predominating class consisted of the engineers engaged in the work of pumping wells, these forming 73.8 per cent of the whole nunil)er. As shown by a comparison of anthracite and bituminous coal, the percentages for the mechanical force and for " all other wage-earners" were greater for the anthra- cite, while miners constituted a larger proportion in the case of liituminous. Those ai'c the natui'al results of the greater diflicult}' of anthraciti' mining and of the necessity of jjrepariijg the product for market after it is mined. In adflition to the foregoing and other facts that a critical analysis of Talile 37 might disclose, it is shown that the mechanical force was especially large for ce- ment, graphite, natural gas, petroleum, and talc and soapstonc; that practical!}' all the wage-earnc'rs em- ployed were directly engaged in remo\'ing the niinei-al in the case of barvtes, buhrstones and millstones, mon- azito, oilstones, whetstones, and scythestones; and that the proportion of employees included under "all other wage-earnei's" was considerably above the average in the case of cement, gypsum, mineral pigments, nat- ural gas, and sulphur and pyrite. RoilH II X 'iriiiji'-earner.s. — Provision was made in the schedule for reporting separately the men, and the boys under 16 years, emploj-ed as wage-earners. Table 38 shows for each mineral the number of men and boys employed, with the percentage that the number of each is of the total number of wage-earners. Table 38. — Wage-earners, men and boyx, hij minerals: 1902. BOYS UNLiEK 1(3 YEARH. 1 Less than one-tenth of 1 per eent. '- Ineludes chrome ore, magnesite, molybdenum, nickel and cobalt, and rutile. 94 MINES AND QUARRIES. The average number of wag-e-earnei.s employed in the mining inclustr3' in 1902 was 581,728, of whom only 11,857, or 2 per cent, were boys under l(j j^ears, which may be considered a small proportion. The statistics of manufactures show that there were 168,583 children under 16 years out of a total of 5,308,406 wage-earners, a percentage of 3.2, emploj'ed in the manufacturing industries in 1900. The reason for the small propor- tion of boys employed in mines and quarries is un- doubtedly the arduous nature of the work and the rigorous conditions under which it is performed in many branches of the industry. Aside from the physi- cal strength and endurance required in nuich of the work, it frequently has to be performed under condi- tions extremely injurious to health and of great hazard to life and limb. In man}' of the industries, as shown by the table, no boys were found, and in most of the others the propor- tion was very small. The industries for which no boys were reported are as follows: Asbestos; asphaltuni and bituminous rock; borax; buhrstones and millstones; corundum and emery; crystalline quartz; Hint; garnet; infusorial earth, tripoli, and pumice: litiiiumore; mica; mineral pigments, crude; monazite; petroleum; precious stones; silica sand; talc and soapstone; tungsten; ura- nium and vanadium; chrome ore; magnesite; molybde- num; nickel and cobalt; and r utile. It should be observed that. for the mineral industries giving employment to but a small number of wage- earners in the aggregate the percentages given may be, and no doubt are, in some cases entirely misleading, as the large proportion of boys may be due to circum- stances which are entirely fortuitous. The highest per- centage shown is for the mining of fuller's eartli, for which 24 boys, or 21.1 per cent of the total number of wage-earners, were reported. They were nearly all re- ported by one large establishment and were employed at the lighter work, such as driving carts and perform- ing certain parts of the processes of drying and grind- ing the product. When the product, after l>eing mined, requires some preparation before shipment, the propor- tion of ))oys is always larger than when the mineral is j sold in a crude condition. This is clearly shown in coal mining, in which industry there were among the employees in both branches, anthracite and bituminous, 10,192 boys, or 86 per cent of the total for the Tnitcd States in all branches of the mining and quarrving industries. In anthracite mines there wei'e 4,561 boys employed, or 6.5 per cent of the total nund)er of wage- earners in that industry, and in bituminous mines there were 5,62s, or 2 pei- cent of the total. The occupa- tions commonly followed l)y tioys below ground are nude driving and door tending. In anthracite mines the rumd)cr of boys below ground was 1.1 per cent of the total number of wage-earners, and in bituminous 1.7 per cent, showing that a somewhat larger propor- tion of boys was i'e(|uii-e(| in underground work in bituminous mining than in anthracite. As a rule bitu- minous coal requires no preparaticm after })eing mined'^ thb "run of mine" is usuall}' marketed in that condi- tion. Anthracite, on the other hand, is always crushed, screened, picked or cleaned, and in many instances washed Ijefore being shipped, and many boj's are em- ployed in the various stages of the process. This is clearly indicated by the statistics. In bituminous min- ing onl}- three-tenths of 1 per cent of the total number of wage-earners were boys working above ground, while in anthracite mining such employees formed 5.5 per cent of the entire number. It is especiall}' noteworthy that for gold and silver mining, in which on an average 36,142 wage-earners were emplo3'ed, only 27 boys, or one-tenth of 1 per cent of the total, were reported, and of this number only 6 worked underground. The number of boys reported in copper and in lead and zinc mining was also noticeably small.

Exclusive of the coal mines, the greatest activity in the mining industries was during the sum- mer months, the largest number being emploved in August. The largest number were employed in the coal mines during December, but the strike in the anthracite t-oal region continued from May to October and greatly reduced the number employed during that lieriod. The number employed each month in the pro- duction of the different minerals, shown in Table 40, indicates that in .some branches of mining the opera- tions were comparatively constant during the year, while in others the activity of the industry varied widely. The-e is a natuial division of mining operations into two main classes, surface and deep mining. Activit}^ in the former is affected, as it is in outdoor industries generally, by the weather and by seasonal changes; while opeiations in the latter class, as a rule, are gov- erned more by the market conditions.

This wide variation marked an abnormal condi- tion — the great strike, which continued from May to October. While it seems that the strike affected all of the wage-earners in the coal industry, the operators were successful in most cases in securing the services of a suiEcient number of men to protect their properties and to preserve them from deterioration and, in some instances, even to mine small quantities of coal. In bituminous coal mining the largest number of wage-earners, 303, 14(;), appears for December. The number fluctuates from month to month, reaching the lowest point, 260,817, in July. Table -10 clearly indicates that in all kinds of mining and quarrying, where the work is done largely in the open air, the period of greatest activity is in summer, while the averages for the winter months denote a time of comparative depression. This condition is shown for clay, limestones and dolomites, marble, sand.stones and quartzites, siliceous crystalline rocks, and slate, and also, although less pronounced, for cement, iron ore, and lead and zinc ore. Phosphate rock, being mined almost entirely in the South where the seasonal changes have less effect, shows a less marked reduction of the number of employees in the colder months than some of those just mentioned. The variation in the average number of wage-earners in gold and silver mining was from 37,333 in June to 34,705 in January, and in copper mining from 27,183 in May to 24,768 in Feiiruary. Ai'i'rtKje eaniinys of 'wuge- earners. — In considering the statistics of employees and wages included in this report it should be understood that it is not possible to draw from the figures any trustworthy conclusion re- garding the average earnings of all those eniplo_yed at stated wages, either by the da\- or piece. The division of the total amount paid in wages to the wage-earners of any industry or of any class bv tlie number of wage- earners in the industry or class results in an unreal and deceptive amount, which is the quotient oi the mathe- matical operation and nothing more. It does not repre- sent the rate of wages of any one class of wage-earners.' A part of the inquiry into employees and wages was framed for the purpose of bringing out the actual daily, rates of pay received by the different classes of wage- earners, and this division of the general subject is treated on pages 96 to 101 of this report. While this class of wage statistics, i. e., actual wage rates, appears to receive the more general approval of statisticians, in preference to statistics purporting to represent average earnings, these rates, unless considered in connection with the duration of the period of employment, are liable to pro\'e misleading, \^'hile a given rate repre- sents the earnings of each wage-earner at that rate for a day's employment, it fails to furnish a true indication as to the annual earnings of the workman, and so falls short of being a correct index of his economic condi- tion, which is better determined by the amount of wages paid to him annually. This is perhaps true more 'This question i.s fully discussed in the Rep.ort on Manufactures for the Twelfth Census. (See Part I, pacjes cxi to cxxv. 1 ^6 M1NP]S AND QUARRIES. especially of niinino- and (luarrving than of other line.s of industry, as operations are fretjuently \'ery ii'ri'gular and spasmodic hy reason of a fluctuating demand for the products. The statistics for anthracite coal may he taken as illustrating- these points. Table 40 shows that for 19oy the least number of men, 6,552, was reported for July, and the greatest number, 119,228, for Febi-uary. The strike of the anthracite coal miners lasted from Maj' 12 to October 23, and the number employed in July may be said to represent the minimum, or the number required to preserve and protect the properties; while the number for February, giving due consideration to the fact that it is an average for the month, is the full quota finding employment in the industry. The amount paid in wages during the j'ear was $.38,716,11;-!, and the division of this amount by the average number of wage-earners for the j'ear, 69, 691, results in a quo- tient of $555, which can be regarded only as an abstract quantit}' indicating the measure of the earnings of a theoretical average employee who worked full time during the year. This, in the light of the actual expe- rience of those employed at anthracite mines in 1902, can only l)e considered as an ideal state of affairs. ^y(| he combined into single groups. The exact rate of pay was not asked foi', and in most cases the distribution of the employees within the 25-cent groups is not detinitel}' known. It ma_v be stated as a general proposition, however, that the greater proportion of the wage-earners included in the various 25-cent rate groups received the lowest rate of those groups. In the case of coal and iron ore miners and other emploj^ees paid in accordance with the amount of work done, very little can be said regarding daily rates of pay. When, wage-earners are paid by the hour there is the same difficulty, for the dail}' rates are then natu- rally dependent upon the hours of employment. How- ever, with the exception of coal and iron ore miner.s and some quarrymen, the great majority of the wage-earners employed in the mineral industries of the United States are paid by the day; and when employees are paid by the da}' their rates are more likely to be in nudtiples of 25 cents than otherwise. For example, the returns show that 6,712 of the men employed in copper mines received between $3.50 and $3.74 per day, and it may be safely stated that most of these men received $3.50 a day. For some minerals the daily rates of the se\ eral occupations arc fixed at figures which are not multiples of 25 cents. But it A\'ould he more nearly correct to take the lowest I'ate in most wage groups as the rate paid to the greater number of the employees included within that group than it would be, for example, to con- sider the rate halfway Ijetween the limits of the group as an average for the entire group. The distri))ution of the wage-earners according to these rates is shown in the following table for each mineral in the production of which more than l,(tOO wage-earners were employed on the average during 1902. The table gives also the per cent that the num- ber at each rate is of the total number; and the cunmla- tive percentage at each rate, which shows what propor- tion of the total number received a wage as great as, or greatei' than, the lowest wage of the given wage group.

The production of the minerals for which separate stati.stics are .shown in Table 41 gave employment to 576,507 wage-earners, this number forming 99.1 per cent of the 581,738 wage-earners reported for all mines and quarries. The average number and per cent of the total number are shown in the table for each rate o-roup. The percentages are also jiccumulated. 30223—04 7 The cumulative percentage is obtained by combining the figures which represent the per cent of total. For example, in Table 11, under the head of "all minerals," four-tenths of 1 per cent of the wage-earners received $4.25 or over and seven-tenths of 1 per cent received between !#4 and i^4.24; adding the two percentages, it is found that 1.1 per cent received $4 per day or over. 98 MINES AND QUARRIES. This process is continued throughout the wuge scale until all the wage-earners have been included, when the cumulative percentage naturally becomes 1C»0 per cent. The cumulative percentage, as stated opposite any wage group, shows then the percentage of the total number formed by the sum of the num1>er included in that wage group plus the number included in all the higher wage groups. Two advantages are gained by the use of the cumu- lative percentage. In the first place, it is possible to determine at a glance the proportion of the total num- ber receiving as much as, or more than, a given rate. For example, if the cumulative percentages were not given in the preceding table, and it were desired to obtain the proportion of the total number who received $1.50 per day or over, it would be necessary to add the nine numbers representing the percentages at each rate from $1.50 up. In the cumulative percentage column this addition is already made, and it is evident at a glance that (iO.l per cent of the cement workers received at least $1.50 per day. The second advantage gained liy the use of the ciunu- lative percentage lies in the fact that it is possible to compare two given sets of returns much more readily than by either the immbers or the percentages in the respective groups. For example, in Table 11 the col- umn headed "cumulative percentage" shows that for cement workers the proportion of the total number receiving fl per day or more was 98 per cent, while for clayworkers it was 81. i! per cent. At $1.50 the respective proportions were &>.l and 28.1 per cent, and at $2 they were 16.1 and 11.2 per cent. The cum- ulative percentages thus show that wages were higher in 1902 for cement workers than for workers in clay mining. Of the various minerals for which statistics are shown separately in the above table the production of anthra- cite and bituminous coal gave employment to the great- est number of wage-earners. A very large proportion of the miners in the coal mines were paid according to the quantitj' of their product, and some of the principal coal comj^anies were unable to classifj^ these employees according to the specified daily rates of pay. When data of this character were not reported bj' the company estimates were made in the Bureau of the Census from the total number of such employees reported, the total amount of wages paid, and the number of days that the mine was in operation, the rate being determined by the average daily earnings for the time emplo^'ed, and the average number for the entire 3'eai' being computed as previously explained; therefore, in such cases all employees of a mine who were paid Ijy the piece or quantity of work done as measured by their output were estimated as receiving a uniform daily rate of pay. There were 2;:!0,846 employees reported as the average number receiving wages according to the quantity of their production, and they were paid 1155,578,988. Of this number, 211,710, or 91.7 per cent, were reported for anthracite and bituminous coal, and they received $144,628,436, or 93 per cent of the amount paid for such mining in all minerals. When the figures for all minerals are combined, it is found that the range of wages for practically all of the wage-earners was from $1 to $3.74 per day, 556,531, or 95.7 per cent of the total number emploj'ed, being in- cluded between those rates. Less than 3 per cent of the total number received less than $1 per da}', and only 1.6 per cent received $3.75 or over. The four rate groups that lead in the number of employees included are con- secutive and constitute the range from $1.50 to $2.49 per day. Between those limits is included 58.1 per cent of the total number. It should be added, how- ever, that the proportion at $2.50 or over is much greater than that at less than $1.50. Of the total num- ber of wage-earners, 57.2 per cent were paid $2 per da}' or more. An attempt to find the median rate (that is, a rate such that half the number of wage-earners re- ceives that rate or more and the other half receives that rate or less) discloses the fact that this rate lies some- where in the group $2 to $2.24. It will also be noticed that the rate group that includes the median includes a greater nimiber of wage-earners than any other group in the scale. In regard to the various minerals, the figures shown in Table 41 may be briefly summarized as follows: (Jement: Of the total number of wage-earners, 73.5 per cent were paid from $1.25 to $1.99. (Jlay: The range of wages for 82.9 per cent of the total numl)er was from $0.75 to $1.74; 35.8 per cent were included in the single rate group $1.25 to $1.49. Void: For a large number of coal miners the figures given rejjresent average earnings and not rates, as most of these employees are paid by the ton or other unit. As the figures stand, they show that for anthracite coal 75.7 per cent of the employees received between $1 and $2.49, and for bituminous coal 76.9 per cent received between $1.50 and $2.74. (Vipjti r iirr: A wide range is noticeable in the wages paid to employees engaged in copper mining. Of the total number 24.1 pei- cent received between $2 and $2.24, and 25.9 pei- cent were paid from $3.50 to $3.74; the remaining wage-earners were distriliuted in smaller groups throughout the scale from $0.50 to $4.25 and over. Gold and x'/lver: Emj)loj'ees engaged in the mining of gold and silver were largel}' concentrated in three groups as follows: 15.3 per cent from $2.50 to $2.74; 33.7 per cent from $3 to $3.24; and 19 per cent from $3.50 to $3.74. Gypsurii : The range of wages for 84.4 per cent of the wage-earners was from $1.60 to $2.24; 51.2 per cent i-eceived from $1.50 to $1.74. Iron ore: Of the total nuniber of wage-earners, 86.8 per cent received between $1 and $2.49; the greatest concentration was at $2; 40.9 per cent of the total num- ber received between $1.75 and $2.24. SUMMARY AND ANALYSIS OF RESULTS. 99 Lead and zinc ore: Almost all, 91.3 per cent, of tln^ wage-earners received between $1.25 and $2.41* per day; 26 per cent receiving from $1.50 to $1.71; and 29.2 per cent from $2 to $2.21. Limestones and doJoiriiteft: The range of wages for 91.2 per cent of the total number was from $1 to $2. 21. Here again there was a marked concentration at two rate groups, 24.9 per cent receiving from §1.25 to $1.19, and 29.1 per cent from $1.50 to $1.71. Marhle: The returns for wage-earners engaged in quarrj^ng marble show a less marked concentration than is observable in most other minerals. There were, however, 58.5 per cent of the total number between the rates $1 and $1.74.

The distribution of the various minerals throughout tiic United States differs so much that, while this table is of intei'cst as showing the total number of wage-earners at the \arious rates of pay in the several states, a com- ])arisoii of the rates paid in one state with those paid iu SUMMARY AND ANALYSIS OF JiESULTS. 101 another is of little value unless the minerals in each state are kept in mind. Thus, according to the figures presented, rates were highest in Montana and lowest in Florida. But since the greater part of the wage-earners in Montana were employed in copper and gold and silver mines, while those in Florida were employed in quarrying phosphate rock, the difference in wages is hardly significant. It will be observed that the states reporting a large number of employees at the low rates are Southern states, while tiiose reporting the greatest proportion at high rates are Western states. The difference in wages, according to geographic location, is more clearly shown in th(^ following table, in which the figures for the various states are comVjined in five groups. The percentage of the total numl;er at each rate is given for each group, as are also the cumulative percentages.

As shown by the above table, rates were much higher in the Western division than in any of the others, 51.8 per cent of the wage-earners in that division receiving $3 per day or over. The three rate groups showing the greatest number of employees are as follows: $2.. 50 to $2.74, 16..6 per cent; |3 to 13.24, 22.8 per cent; and $3.50 to $3.74, 18.3 per cent. In this group of states are included almost all of the gold and silver and copper mines of the countrv^ The wages in the North Central division were con- siderably lower than those in the Western division, but higher than those in either of the three other divisions. The range of wages for the majority of the employees, 83.3 per cent, was from $1.50 to $2.74, the rate group showing the greatest number of wage-earners being that of *2 to $2.24, which includes 28.7 per cent of the total number. In this North Central division are in- cluded the iron mines of Michigan and Minnesota, the coal mines of Ohio, Indiana, and Illinois, and the oil wells of Ohio and Indiana. The rates of pay in the North Atlantic division were only slightly lower than those in the North Central division. The bidk of the employees received between $1.25 and $2.49 per day, 73.2 per cent being included between those rates. Over 70 per cent of the wage- earners in this division were employed in the coal mines of Pennsvlvania. Wages were lowest in the South Atlantic and South Central divisions, there being very little difl'erence between the two sections. In each section 78.8 per cent of the total number were included between the rates $1 and $2.49. IX. CONTRACT MINING AND QUARRYING. By reference to the copy of that part of the sched- ule of inquiry which relates to employees and wages, shown in Appendix A, it will be seen that operators were required to report mining or quarrying which was paid for otherwise than bj' the day. The inquiry was made a part of the schedule in order to determine the con- ditions of emploj'ment of those engaged in the actual work of mining and the extent to which such work was done under other terms of paj'nient than daily rates. To indicate the extent to which such work was done in the different kinds of mining. Tables 45 and 4() are shown. Table 45 gives the total average number of miners and miners' helpers, and quarry- men and stonecutters, with the amount paid in wages to this class of employees; also the average number of contract miners, with their wages and the percent- age the number of contract miners forms of the total number of men engaged in mining and their wages form of the total wages, respectively. 102 MINES AND QUARRIES.

It .should be understood that the contract mincr.s and quarrjanen reported in the above ta)ile were not em- ployees additional to tliose shown under wage-earners by classes, but are included there and also in the tables showing wage-earnei's by specified daily rates of pay and the average number employed during each month. Of the total number, o43,16j the car, 254 mines reporting that method, as compared with 26 by the ton and 7 by the yard. It should be stated that when payment by the yard is in the form of allowance only, it has not been in- cluded in Table 46 as a method of payment. The subject of allowances in addition to the regular schedule of rates for coal mining receives the careful consideration of both the opei'ators and the miners. The fac.'t that 7.6 per cent of the wages paid for con- tract work was in the form of allowances indicates the prime importance of this ft.'ature of wage payment in the economical administration of the properties. With- out this system no equitable and uniform scale of wages could be arranged. These allowances are nearly always fixed ])-y the fore- man in charge of the mine, and usually result from a conference as to the equities of the case between him and the miner interested. It will be observed that ac- cording to Table 46 allowances were made in every state and territory separatel^y shown, the amount rang- ing from f3, 940, 090 for both anthracite and bituminous in "Penn.sylvania to $2,700 in Oregon, and the percent- age that the allowance is of the total wages paid for contract mining from 21.4 per cent in Michigan to 2.8 per cent in Virginia. The schedule called for the rate of paj^ment by the ton, car, j'ard, or otherwise, and a mass of information was received bearing upon this point. However, the verj' wide range of the rates and the complexities of the subject generally have defeated anj' statistical pre- sentation of the data reported. The amount paid for contract mining in the iron ore industry was $5,090,832, which was 42.8 per cent of the total amount paid to miners in that indu.stry. The num- ber of wage-earners so employed was 8,105, or 38.9 per cent of the total number of miners. Payment for con- tract mining in this industiy was principally by the ton ;uid bv the tram, and occasionallj' by the yard, with a wide range of rates. The number of contract wage-earners engaged in quariwing limestones and dolomites was 3,772, or 17.1 per cent of the total number of contract quarryuien and stonecutters, and the amount of wages paid was §1,482,678, or 14.5 per cent of tlie total for such work. The u.nit upon which payment was based was very irregular, as payment was reported by the tram, ton, foot, yard, perch, and bushel. In gold and silver and lead and zinc mining the pro- portion of contract mining was very small and indi- cates that most of the work was done by the dav. In lead and zinc mining contract mining was exceptional, as the amount reported was onlj' $266. In those mines, however, where the landowner or first lessee was also the buyer of all ore mined by the sublessees, the latter were virtually wage-earners paid by the ton. The total number of such sublessees reported was 638 and the total amount paid to them was $244,661; out of this amount they were required to furnish their own sup- plies. In the tabulation of the statistics these sublessees in lead and zinc were regarded as proprietors and are not included in Table 46. 104 MINES AND QUARRIES. Contract mining was reported for only a .small num- ber of copper mines, and tlie.se were all in Michigan, no work of that kind being reported for the argentifer- ous copper mines of the Rocky mountain region. The average number of contract miners was 2,200, or 1.5.7 per cent of the total number, and the amount paid was $1,601,091, or 12.9 per cent of the total wages paid for mining copper ore. Drifting, as reported, was paid for by the foot, the rate ranging from $.5.75 to $7.71. Slop- ing was paid for at an average of about $.S per cubic fathom. In barytes mining 71.1 per cent of the miners worked by the piece system, and according to the reports, re- ceived payment by the ton, the rates ranging from $2 to $3.50. Only a comparatively small percentage of cement- rock mining was done by contract. Payment in such cases was by the ton and there was a wide range of rates. Contract clay mining was paid for bj' the ton, the rate ranging from 13^ to 75 cents per ton. The rate paid for mining gypsum on contract ranged from 20 to 65 cents per ton, with mo.st of the operators reporting a rate between 40 and 50 cents. Thirteen and three-tenths per cent of the wages paid for quarrying sand.stones and quartzites was for contract quarrying. The unit upon which payment was based in this industry was the same as in the quarrving of lime- stone and dolomites and siliceous ciTstalline rocks, ver}^ irregular, as payment was reported by the tram, ton, foot, yard, perch, and bushel, and the rates varied more widely. A large proportion, 68.5 per cent, of the mining of crude mineral pigments was Ijy the ton; the lowest rate reported was 40 cents and the highest $5 per ton. Most of those engaged in monazite mining, while working independent!}' of any proprietors, were re- ported as wage-earners on contract, as elsewhere de- scribed. The crude monazite obtained from the placers was sold by the miners at the rate of 4 cents per pound, and this was treated in the statistics as the rate received by them for contract mining. Approximately one-fourth of the mining for phos- phate rock was by contract. In a few instances pay- ment was made by the car and j'ard, but in most cases it was by the ton. The rates ranged from 25 cents to $5 per ton. The latter amount was paid by an estab- lishment in New Mexico, where the product was a bat deposit found in a cave and difEcult and expensive^ to mine on account of its location. Contract slate quarrying was by the square, and the lowest rate reported was 70 cents and the highest $2.25. As shown by Table -45, there were several otiier indus- tries for which small proportions of contract mining were reported, but the amount and percentage of the figures are comparati\'ely unimportant. X. CONTRACT WORK. In nearljr all branches of the mining and quarrying industry occasions arise which demand considerable outlays for work that is ditferent from the regular pro- duction of the ore or mineral — work such as tunneling, shaft sinking, boring test holes, and removing top earth where open-cut mining is intended — and this is frequently let to contractors who make a specialty of the work in question, usually to the lowest bidders. Table 47 shows for each mineral the value of the prod- uct, the amount paid for contract work and the number of employees engaged in it, and the per cent that the amount paid for this work is of the value of product.

When the schedule of inquiry was drawn up the diffi- culty of obtaining complete and correct information in regard to contract work, cspeciallj^ concerning the SUMMARY AND ANALYSIS OF RESULTS. 105 number of men emploj'ed and the number of days required to eomplete the work, was fully appreciated by -the officials of the Bureau of the Census and by experts who were consulted in the preparation of the schedule. It was believed that in inost cases it would be impossible to locate the contractors. Generally no record is kept by the mine operators of any other data relating- to contract work than the amount paid. The number of employees and the duration of the con- tract are matters of less concern to them. However, it was thought that the close attention they are obliged to pay to the work during its progress to insure strict compliance with the terms and specifications of the contract, would enable them, in the absence of records, to make a fair estimate of the data. This was realized in the course of the canvass, and the statistics are published with no pretentions that they can be re- regarded as strictly correct, but under the conviction that they are reasonabh' accurate considered as sta- tistics which are in part estimated. The employees reported under this inquiry are not included among the wage-earners and should not be considered as forming a part of the wage-earners reported by classes, and at specified dailj' rates of pay, nor of the average number reported for each month. No conclusions can be drawn from Table 47 as to the amount paid to contract employees, nor in regard to the average number for the entire year. As to the latter, indeed it is quite possible that some of the em- plo3'ees are duplicated in the figures. The amount paid represents the entire cost of the contract work, including the wages paid, the cost of all supplies and materials used, other miscellaneous ex- penses, and the profits of the contractors. These ex- penses var}' in their proportion to the whole cost according to the kind of work. In drilling wells for petroleum and natural gas, as a rule the cost of mate- rials is greater in proportion than in any other de- scription of contract work. The drilling carries with it the obligation to provide casing, tools, and all other supplies required to equip the wells; and in building the rig, all materials are generally furnished by the contractor. In shaft sinking, also, materials and sup- plies such as timber and explosives forma considerable proportion of the whole cost. While no particular statistical value can be attached to a comparison of the cost of contract work with the value of product, yet always keeping in mind the fact that the figures are not fully representative of this class of work, a great deal of it being done by the regular employees of the mining companies, the table will serve to show the proportions of both with re- spect to the value involved. Table 47 shows that the amounts paid for contract work and the percentages that these form of the value of the product are greater in the case of petroleum and natural gas than for an^' other mineral. In the crude-oil and natural-gas industry practicallj' all of the development work, pro.specting, and equipment of the properties are done by contract, which explains the large amount expended for such work. The regular em- ploj'ees of the producing companies are nearly all en- gaged in the maintenance and oi^eration of the wells. The number of employees reported as employed on contract work in this industry approaches more nearly the true average number for the year than in any other. As explained on page 20 of this report, the Standard Oil Company made reports covering the entire produc- tion of crude petroleum, with the exception of a few producers of heavy oil, in Pennsylvania, New York, Ohio, West Virginia, and Indiana, and combined reports of its own production for Kentuckj' and Kansas, with- out separating the production Vjy counties, as was gen- erally required Yjj the Bureau of the Census. Also, for natural gas the company reported for its subsidiary or contributary companies the production in Penns3'lvania, New York, Ohio, and West Virginia, making a single report for each state. In reporting contract work the amount paid was given, but it was stated that the num- ber of men emploj^ed could not be given, and in lieu of exact information the average number of men required for each well and rig and the average time required to complete the work at each well were reported. From these data, using as a basis the number of wells drilled during the year and assuming that operations were con- tinued throughout the whole j^ear on full time, the average number of men employed was computed. While the figures, therefore, are pure estimates, if the information furnished hy the company is accurate they may be accepted as fairly representing the statistics for this branch of the industry'. Taking into consideration the fact that the amount paid for contract work in the petroleum and natural-gas industries, §17,415,63^, is 84.2 per cent of the total paid in all mining and quarrj'- ing industries, $20,677,938, and that the number of em ploj'ees in these industries, 11,217, is 53per centof the total, 21,183 — with the additional consideration of the great preponderance of the Standard Oil Company's interests over those of all other oil producers — an idea is obtained of the extent to which the total number of employees engaged in contract work in all the industries is afl'ected by the estimates which were made necessar3^ The amount paid for contract work in coal mining was $1,650,53.5; in anthracite $406,421, and in bitumi- nous $1,244,114; and the nimiber of employees was 6,771 — in the former 1,731, and in the latter 5,040. The information was generally reported bj" the coal operators very completelj'. No reduction of the num- ber of employees reported to the average number for the vear was made, and the number given in the table 106 MINES AND QUARRIES. may contain duplications, as there was nothing in the reports to show whether or not a force of employees engaged in a contract and so reported was not again reported for another contract, taken after the comple- tion of the tirst for a different operator and both dur- ing the census 3'ear 1902. Unlike those engaged in deep mining for the precious metals — for copper, iron, etc. — coal miners, engaged as the}' are in mining a ma- terial more easily worked than the surrounding rock and which is alwa3's found in well-detined veins, are usualh^ unsuited for what is termed "rock work." Therefore such work as tunneling, shaft sinking, boring test holes, etc., is in most cases done more economicallj' under the contract system. The larger companies, how- ever, frequently maintain a force of men especially for that purpose. The amount reported as paid for contract work in gold and silver mining was $626,09(>, which was only eight-tenths of 1 per cent of the value of the product of the mines. The work was very similar to development work in other kinds of mining. In some cases, where considerable depth had been reached and pumping had to be done on an extensive scale, it was at times impossible for one mining company to pump the water from its mine without at the same time clearing all adjacent mines. This work was therefore most conveniently done by contracting firms or companies with whom the business had become a specialty. The amount paid for contract work in iron ore min- ing was $425,292, and there were 1,079 men employed. The work was similar in character to that done in other branches of the mining industry, except that there may have been a larger proportion of stripping preparatory to open-cut mining. It should be explained that in the data shown in Table 47, in addition to the amount paid for work other than mining which was done by contract, there is included the amount paid liy private operators to state and municipal penal institutions for the lease or use of con\'icts in the operation of mines and quarries. A careful examination of the reports received shows that $530,. 311 was paid for this purpose. The laws of certain Southern states per- mit the lease of convicted prisoners to private persons or firms for work outside of the penitentiaries. Amono- the states liy which this is done are Alabama, Arkansas, Florida. Georgia, Kentucky, Louisiana, North C'arolina, South Carolina, and Tennessee. This is entirely apart from the work of con\'icts in mines or quaiTies owned by the state. The only states in which the convicts were reported to have been leased to work in mines and quarries, and to which the amount abo\e reported, ?.530,311, was paid, are the following: Alabama, coal; Florida, phosphate rock; Georgia, ccjal and iron ore; North (jaroliria, limestone. In addition to the contract work shown in Table 17, a lai'ge amount of such woi'k was done at mines and quarries which did not produce any mineral in 1902, but at which development work of some kind was done. The amount paid and the number of employees engaged in contract work at idle mines or those in process of develojiment are shown, bj- minerals, in the following table: Table 4:8 . — Contract work at nonprodncing mines, by minerals: 1902.

Contract work was reported in greatest amounts from petroleum and natural-gas wells among productive properties; the largest amount of contract work at mines for which no production was reported was in the development and improvement of gold and silver mines. Petroleum and natural gas, iron ore, and bituminous coal follow in the order named. XL PKODUCTIOX WITHOUT EMPLOYEES. Speaking ))roadly, it required the .services of 619,856 wage-earners and salaried employees, to whom was paid $108,980,512 to produce in 1902 the mineral product of tiie United States, which was valued at $796,826,417. The (conditions of mining and quarrying were such as to call for the employment of at least one person at a very large proportion of the plants, and in some branches of the industiT the investment of capital in Ituildings and mechanical and other equipment and the organiza- tion of the working force were equal to those features of industrial organization in the largest and most impor- tant manufacturing establishments. On the other hand, in certain branches of the industry operations were con- ducted at many mines and quarries under conditions of the gr-eatest simplicity with no hired labor and no me- chanical e(iuipment, with the exception of a few tools. Table 19 presents for each mineral the number of mines or quairies at which there were no employees, the pro- prietor doing all the work; also the value of the output of such establishments, and in adjoining columns, for purposes of comparison, the total number of mines and ([uarries and the value of their product with the per- centage that the product of the class reporting no em- ])loyees forms of the total.

Of the 4,109 operators engaged in the production of bituminous coal, 2,130, or 48.3 per cent, reported the payment of royalties varying from eight-tenths of 1 cent to $1.50 per ton. The rates most commonly reported were from 5 to 15 cents per ton, there ))eing 1,850 oi^erators paying royalties coming within these amounts. The amount paid as royalties and rent in the produc- tion of petroleum was reported as $8,929,891, being one- eighth of the value of the product. In the majority of instances tiie royalty was a percentage of the oil pro- duced. This percentage ranged from a fraction of 1 per cent to 50 per cent, l)ut the usual amount of petro- leum paid to the landowners was one-eighth of the amount marketed or sold to the pipe lino companies. In a few cases a fixed amount was paid for each barrel. In northern Pennsylvania and southeastern Ohio a com- paratively small amount of superior petroleum was pro- duced, for which the operators paid one-sixth. Part of the petroleum produced in Kansas and Texas, and practically all of that produced in California, paid one- tenth. The manner in which the amount of royalty to be paid is determined and the method of payment is SUMMARY AND ANALYSIS OF RESULTS. ns de^^cribcd by Mr. F. H. Oliphant, in the United States Geolog-ical Survej^ raonograpli, "The Production of Petroleum," li)0:i,' pages 41 and 42.' In the production t)f natural gas $2,5:38,8y.5 was re- ported as rent and royalties. The usual rent paid for ;i gas well was from llOO to 1300 per year. ' ' The pipe line company, upon npplication from the proriucer sends an agent, generally known as a " granger, " to measure and inspect the petroleum in his tank and run it into its lines, the tanks throughout the held having Ijeen earel'ullv measured and a card issued showmg the numlier of barrels t'roui top to bottom to each inch of liquid. From his blank book tlie ganger gives the ojierator a "run ticket," sending a duplicate to the nearest general office as well as reporting the amount by telegrajih, keeping a tliird one himself. The pipe line company deducts the amountdue the owner of the property acconling to the terms of an agreement on file at the office, known as the royalty, and tlie next day the i>rodncer can secure the cash for his petroleum at the market quotation for the day or hour of his sale, at the nearest home office of the com- pany, from a purchaser for the relining companies; or, if tiie pro- ducer Avishes, he can obtain a certificate when his production in the tanks of the pipe line company amounts to 1,(1(1(1 barrels. These certificates are made payable to bearer, and are therefore transferable. They are subject to a transportation charge in the district of 20 cents per barrel and a charge for storage at the rate of 25 cents per day per 1,000 barrels when the price is less than |1, 30 cents when over SI and under $1..50, and 40 cents for all over SI .50 per barrel. They are to be returned for exchange t(j the pipe line company within six months after issue, or be subject to a charge of one-twentieth of 1 per cent daily thereafter until ex- changed. To cover losses bj- fire or lightning'certificates are subject to an assessment pro rata on all oil in the custody of the pipe line. None of these charges are included in the prices of petroleum as quoted, and therefore the prices given are the prices at or near the Avells. This system, by which the operator can alwavs find a mar- ket for his production at a common price known to "all, has done much to develop the oil resources of the United States. Other countries have suffered where there were no organized lines of transportation and storage to enable the producer to dispose of his products regularly. ^The form of lease for petroleum and gas wells is generally as follows: . .V D. 1911- , part . -, Ijv and f the first Agreement made and entered into the day nl between , of , county of and state of part, and part of the second part.

The operators in tlie states of Michigan and Minnesota paid $5,903,(514 in royalties and rent, or 00.8 per cent of the total amount paid in the United States. Of the 7'2 operators reported for these states, 61 paid either rent or I'oyalty. The state of jNlinnesota has adopted a system of leasing its iron lands for a term of j'ears to prospectors and miners, and a royalty of 25 cents per ton is imposed on all iron ore mined and shipped from state lands. The state has received $332,119.02 in roy- alties on iron ore actually shipped up to the end of the fiscal year, -luly 31, 1902, and by annual payments on mining contracts, payment for prospecting leases, and 114 MINES AND (,)UARR1ES. as royaltj' on a minimum output of 5,00(» tons per year, the further sum of $212,515.75 has been turned into the state treasury, making a total of $544,634.77/ Zinc mining lands are seldom sold, hut are usually worked on royalties. Lands whieh have never been pros- pected are leased on a percentage royalty. The lessee prospects the land and lots are then subleased to mine operatoi-s at a larger percentage royalty than is paid by the first lessee. The first lessee usually contracts to put in pumping plants and keep the tract drained. The ore is sold in the bins and payment is made to the landowner or first lessee, who deducts his rovalty and pays over the balance to the operator. Very f recpiently the sublessee further leases small plots to miners, usually neighboring farmers, who undertake to «(.)rk the land on a royaltv. The larger land companies Iniy all ore produced b\' these miners at a stii)ulated price, deducting from it the royalty. In such cases the terms resemble contract mining as practiced in other branches of the mining industry. The total amount of royalties reported for zinc mines at the Twelfth Census was '11,535,368. The royalty is computed on the price paid bj^ the purchaser for ore in the bin.s; if the ore sells at S3U per ton and the royalty is 2(.i per cent, the land- owner deducts $6 per ton for his royalty and draws his check for $24 to the operator. Mining on royalties is of little importance in the cop- per mining industry. The total amount of royalties and rents jmid in 1902 was $130,215, of which only $33,184 represented royalties. This was about 25 per cent of the gross value of the ore upon which the royal- ties were paid. Considering that the total production of copper ore was valued at $51,178,036 at the mine, it is apparent that royalties can not be considered a factor in copper mining. In gold and silver mines the royaUy is usuallv stipu- lated at a certain jjercentage of the net value realized for the ore, after deducting treatment charges and freight; the rate increases with the grade of the ore. Thus if the ore is worth $20 per ton, the cost of treat- ment and freight is SIO. and the rate of rovaltv is 25 ' Report of the auditor of the state of Miniie»jta for the fineal ve;ir einhng .July 31, 1902. per cent; then the landowner is paid $2.50 per ton, which leaves $7. 50 for the operator. Sometimes, though seldom, the rate is stipulated upon the gross value — say 10 per cent of the assay value of the ore; taking the same figures as in the preceding example, the rbj'altj^ would amount to $2, which would leave for the operator $ls, from which $10 would be deducted for treatment and freight, leaving a net balance of $8 for the operator. In Colorado, where the mines arc often leased in " blocks " to miners who perform the labor personally, the ore is marketed by the owner oi' shipped in his name, and he deducts his royalt}' and pays the balance to the lessee. AVhen the ore is sold to a "sampler" (ore buyer), he frequently withholds the royalt}' for the owner and pays the balance to the lessee. XV. COST OF SUPPLIES AND MATERIALS. The cost of supplies and materials of all kinds used in the mining industries during the year, including freight on the same when paid by the mine operator, amounted to $123,814,967. This includes luml.)er and timlier used for repairs, mine supports, track ties, cars, and other puri)oses; iron and steel for lilacksmithing, rails, frogs, sleepers, etc., for tracks; miscellaneous ma- terials, parts of machinery, and tools used for renewals and repairs; and also explosives, water for boilers and other purposes, fuel, illuminating and lubricating oils, machinery, supplies, etc. Supplies may have been pur- chased with the intention of taking advantage of low prices, but only the cost of those used during the year was reported. The " material "' operated upon in a mine is the mineral in place, and its cost is included in the cost of the land or in the amounts paid for royalty- and rent. All the items here enumerated t'ome under the definition of "supplies," and the total cost may be ac- cepted as representing the purchase of supplies, with the exception of the purchase of lime rock by quarry companies engaged in the manufacture of cement. The totals are simmiarized in Table 54 and placed in com- parison with the value of product for each mineral and gKuqi of minerals.

They show only the relative importance of this item of expense for all mines, irrespective of the conditions under which they were operated. The total amount paid for sup- plies and materials for the entire mining industry was 15.5 per cent of the total value of product. The per- centages that cost of supplies and materials formed of the value of the product ranged from O.-l per cent for monazite to o7.5 percent for cement. The high pro- portional cost in the latter was due in part to the fact that some crude cement rock was purchased from (juar- ries that were not equipped for manufacturing cement, and large amounts were paid for cooiaerage stock, bar- rels, and other packages in which the product was packed for shipment. XVI. powf:r and machinf^kt. The use of power is liecoming more general in all braiu-hes of productive industry. In the mining indus- tries power is employed for ti vtiriety of purposes, the chief of which are the operation of hoisting, draining, ventilating, conveying, drilling, and cutting machinery, derricks, steam shovels, and locomotives and hauling engines. It is also employed extensi\'ely in the opera- tion of machinery used in crushing, screening, clean- ing, or otherwise treating the crude material. Motive power is now generally used in all mining operations of ail}' magnitude.

The value of the products reported by opera- tors using power amounted to $732,324,;3T(>, or '.tl.'.l per cent, of the total value of products for all operators. In other words, all ))ut S.l per cent of the mineral products of the country Avere obtained l>v opcratoi-s who reported the use of power to some extent. The entire production of anthracite coal, bora.x, fuller's earth, magnesite. and rutile was obtained by operators using power. For ten of the ditferent classi- fications of minerals enumerated in the above table the use of power was reported by operators producing more than ;>5, but less than 1< lO per cent of the value of product. Of the seven groups of minerals the metallic group shows the largest proportion. 95.1 per cent, for the products obt*iined by operators using power. ' The next largest proportion, 91.9 per cent, is shown for the group of fuels, while for the remaining groups the per- centages of the products obtained by the use of power are as follows: 91.2 per cent for chemical materials. 86.2 per cent for structural materials, 72.5 per cent for miscellaneous materials, i9.8 per cent for pigments, and 48 per cent for abrasive materials. The table shows verv conclusively that practically all of the large pro- ducers employed mechanical power in some form. In compiling these statistics, steam, gas or gasoline, and water were considered as primary power, and rented power of all classes was included under the same head. Gas engines embrace all forms of internal combustion engines in which the propelling force is the explosion of gaseous or vaporous fluid in direct contact with a piston within a closed cylinder. The incjuirv concerning mechanical power called for a full report of all power employed, either owned or rented, includ- ing the number and horsepower of all engines, motors, water wheels, etc., used for ventilating. jDumping. hoisting, derricks, surface machinery, and all other purposes. The power reported inanswer to this inquiry amounted to 2,867,562 horsepower for all branches of mining. Of this total. 2,432,963 horsepower, or 84.9 per cent, was steampower; 60,897 horsepower, or 2.1 per cent, was waterpower; and 373,702 horsepower, or 13 per cent, was obtained from other forms of mechanical power, including electricitj% gas engines, air compressors, etc. The use of steampower largely predominated in mining- operations, other forms of primary power in com- parison having only a limited application. AVhile inquiries concerning power were included in the schedules used at previous censuses, they do not appear to have been answered uniformly, and the comparisons can not be accepted as an accurate indication of the increase in the quantity of power employed. The following tal;)le, however, presents the total horsepower reported at the censuses from ls7() to 1902: Tabl].; 5(). — JIunepoiixr: ISIO lo 190s!. TOTA), HORSEPO\VKR.

Since statistics for power were not reported in a uni- form manner at these censuses, the totals for the Fnited States are not shown in Table 56. The figures can be accepted only as an indication of the more general use of power in mining operations and not as a liasis for computing the actual increase in the horsepower em- ployed in the industry. The inquiry for 1902 was con- fined to the operation of mines, quarries, or wells and such manufacturing processes as were carried on in immediate connection therewith. A number of min- erals for which power was reported at the census of 1902 were not produced in commercial (juantities at one or more of the three preceding ceirsuses, or if thev were so produced, power was not reported as employed in the mining operations. The detailed statistics for the different varieties of 118 MINES AND QUARRIES. power reported for each mineral, eaeli group of min- erals, and for all minerals in each state are shown in Tables 1 and 2, jiages 347 to 377.

In the center is a vertical rotating post, to whose raflial arms are attached blocks of stone or mullers, which are dragged over the ore in the inclosure, thus crushing it. Ball grinder: A pulverizer for minerals. It depends upon the attrition of spheres rolling inside a rotating cylinder, the periphery of which is provided with a cast steel ring, perforated with small holes. The heads of the cylinder are of heavy cast iron, lined with steel. It contains several steel balls from 2 to 5 inches in diameter. The steel ring is the crushing plate upon which the balls break up the material to a size varying from a i>owder to the size of the holes in the ring. In some cases a single large ball is used, moving in a grooved path. Boring machine: See Drill; Hydraulic boring machine, etc. Breaker: A machine for reducing ore as it conies from the mine to an approximately uniform size convenient for further working. In jaw crushers the ore is broken between a stationary and a movable jaw. Gyratory crushers, often called "coffee mill" crushers, are in part an application on a large scale of the principle (if the ordinary household coffee mill. See also Coal breaker; Roll crusher; Ball grinder; Stamp mill, etc. Buddie: One of that class of concentrating machines depending upon the principle of the settling of minerals in the order of their specific gravities. In round buddies the tables are convex-conical or concave-conical. In the stationary buddle the pulp is fed from slowly revolving feed pipes running from a main pipe in the center, and discharging at the circumference of the table, if an inward- flow buddle; or from a slowly revolving central feed, if an outward- flow buddle. In the revolving buddle the table revolves, while the feed is stationary. Distributing brushes spread the deposits evenly over the surface of the table. Bumjnng tidjle: A suspended table, capable of liniited movement, which is subjected to a series of Vilows or shocks in the plane of its motion. Chain enller nnieliine: .Machine used to shear or undercut coal. It consists (if a low metal bed frame, upon which is mounted a motor that rotates a chain, tn which suitable cutting teeth are attached. It can be used only under certain conditions, viz: When the coal is comparatively free from balls of iron pyrites, or when the roof is good and props are not used close to the face of the coal. It can nut be used to undercut coal having a squeeze upon it. ^lachines of the ordinary type perform their work by making a furward cut under the C(jal, then being withdrawn and moved (iver tii reaili fresh coal. This process is repeated across the face of the room. The Sullivan machine is fed under the coal but once, and then makes a continuous cut across the face, being withdrawn iinl\' at tlie farther side of the room. .ClianneliiLg machine: A machine for making channels in stone; that is, cutting the stone intci blocks without the use of explosives. Its several forms are the track channeler, being a machine mounted on a truck running on a track, carrying a boiler furnishing steam to the machine; or the boiler may be omitted, the machine being driven by compressed air from mains; or the truck may carry a reheater for reheating the compressed air before it reaches the machine; the undercutting track channeler, similar to the above, but without boiler and cutting, horizontally; the bar channeler, in which the cutting machine travels on a stationary bar. Any of these machines may lie driven by either steam or compressed air. Chilian mill: An ajiparatus in which the ore is crushed under vertical rollers running in a circular inclosure with a stone or iron base or die. The rollers rotate on a horizontal axis and also around a common vertical center. (Mai breaker: A machine for crushing lunqi coal as taken from the mine. It is also adajited for deansing and sorting. SUMMARY AND ANALY8LS OF KE8ULTS. 121 Coal coiivei/er: See Conveyer. Coal cutter: See Pick machine. Coal v'((xhi'i-: A macliine in whicli coal tliat lias lieen broken and assorted is finally washed to deprive it of the .hist and dirt adhering. (-'oiiiiircsxoi-: See Air compressor. Concentrator: General name apjilied to all machines for concen- trating the mineral values of an ore to a smaller hulk in order to get rid of as much superfluous material as practicalile. Convener: An endless belt or chain device for transporting ore or coal. Crossover duntj): A contrivance for duiiipiiig cars on the mine tipple, which automatically dumps the i-ir, restores it to its original position, and returns it to the mine. Crusher: See Breaker. Diamond drill: See Drill. Dredge: A machine used in placer mining where streams can not be diverted from their course so as to expose the bed, or where bench placers do not have sufficient water for hydraulicking. A floating dredge is used for mining gravel under water; a traction dredge tor "dry" or land mining. Dredges may be divided into two classes — those using a line of buckets on an endless chain, and those of the liipper type, which use a single bucket like a steam shovel. Drill: A machine operated by steam, electricity, or compressed air, for boring. They are of two classes, percussive and rotary. A percussion drill consists of a cylinder in which works a piston carrying a long piston rod, and which is supported in such a man- ner that the drill, clamped to the end of the piston rod, alternately strikes and is withdrawn from the rock as the piston reciprocates back and forth in the cylinder. Means are provided by which the piston rod and drill turn slightly on their axis after each stroke. Rotary drills differ from percussive drills in the fact that the drill makes its way into the rock by a boring action produced by the axial rotation of the drill rod. Diamond drills are of the latter class, the drilling tool being a hollow cylinder armed with diamonds on its cutting end. See also Hydraulic boring machine; Gadder, etc. Drill steel sharpener: A device driven by compressed air for sharpening steels for drills, channelers, etc. Electric drill: See Drill. Electric locomotive: See j\line locomotive. Electric pump: A mine pump oj^erated by electricity. Elevator: A machine, consisting of series of Ijuckets attached to an endless chain or belt, for lifting materials from one height to another. Feeder: A machine for automatically delivering ore in proper quantities and at a definite rate to stamp batteries, roll grinders, etc. Oadder: A machine by which holes are inserted into the side of the bench, for the insertion of plugs and feathers, by means of which the blocks are separated in the quarry. It may be driven by steam or compressed air. Gravity stamp: See Stamp mill. Grinder: See Breaker; Ball grinder; Stamp mill, etc. Haidage engine: A stationary engine for hauling mine cars Iiy means of tail rope or endless rope systems. Header: A machine used principally for entry dividing, especially where it is not desired to make lump coal, and wdiere the work must be pushed rapidly. The machine cuts a cylinder of coal about 4 feet in diameter and about 5 feet in length. Hoisting engine: An engine for hoisting men or materials from a mine. Hgdraidic boring machine: A machine in which the rock drilling machine is actuated by the force of water under pressure, conducted by pipes to the breast of the tunnel. Hydrcmlic coed miner: An apparatus for breaking down coal by means of an expanding plug worked by hydraulic pressure. Jam crusher: See Breaker. dig: A macliine in wliich concentration is effected by giving a column of water a pulsating motion, or by giving the grating and screen, iijion which a bed of ore lies, a short reciprocating motion, the resistance of the water lifting upi the bed on the down stroke of the piston or grating and the particles assorting themselves as they settle back. The principle of the jig is the tendency of the j)articles of a bed of ore in water, when approximately of the same size, to arrange themselves in layers according to their specific gravity when the bed is kept sufficiently open to allow the parti- cles to move freely among themselves. Keere: A round tub in which the separation is effected by means of stirring paddles, attached to and operated by a vertical shaft passing up through the center of the tub, and by hammers auto- matically striking the outside of the tub. Long-wall -mining machine: A machine especially designed for undercutting a long-wall face. It consists of an engine or motor mounted on a bed frame and a large cutter wheel in the periphery of which arc placed the cutters or bits in a manner similar to that employed in setting the cutters in a chain cutter machine. The bed frame is mounted on wheels which run either on a single rail or an ordinary track laid parallel to the face of the coal. In machines of the Sullivan type the cutter consists of a bar of oblong shape, on which runs a chain carrying cutters or bits. This bar is similar to that used in the chain cutter machine. The machine travels along the bottom of the mine on a flat steel shoe, rails Ijeing unnecessary for its operation. The machine takes its motion along the face from a feed chain. Mechanical conveyer: See Conveyer. Mill: See Stamp mill. Mine locomotive: Small, compactly liuilt locomotive for use in mines. In the steam mine locomotive the water tank is set over the boiler, and the smokestack and top of the cab are on a level low enough to permit entrance into the mine passages. The com- pressed air locomotive requires a stationary air compressing plant and usually pipe lines to convey the compressed air to convenient points in the mine for charging purposes. The electric locomotive also requires a power generating station and is operated in a manner similar to an electric trolley car, using a conducting wire along the haulage road. A variation of the electric mine locomotives is the rack rail locomotive. This locomotive is propelled by sprocket wheels that mesh with the stationary rack laid parallel with the rail, the object being to obtain a great drawbar pull from a light locomotive of small outline dimensions. It is also able to climb steep grades. The electric current is carried to the locomotive in the rack and returned in the track rail. Ore breaker: See Breaker. Ore conveyer: See Conveyer. Ore crusher: See Breaker. Pick machine: A reciprncating percu.ssive machine used to shear or undercut coal, etc. In undercutting the machine is mounted on small wheels; in shearing, these are removed and large wheels substituted. Pneumatic drill: See Drill. Pneumatic pu in j>: A pump operated by compressed air. Pneumcdic stamp: See Stamp mill. Ptdsometer: A water raising device on the principle of the Savery engine. It will raise water by suction to a height of about 26 feet and, if necessary, force it to a height of about 100 feet. Its utility in mining operations lies in the fact that it will pump anything that t'an get jiast the valves, including mud, gravel, etc. Pulverizer: See Boll crusher; Ball grinder; Stamp mill, etc. Puuip: See Steam pump; Sinking pump; Pulsometer, etc. Riddle: A shaking screen with plane surface. They may be divided into four groups — shaking screens having an endwi.se or sidew ise motion in the plane of the screen, or nearly so, with or without a bump; pulsating screens having an up-and-down motion perpendicular, or nearly so, to the plane of the screen; gyrating screens with a circular or elliptical motion in the plane of the 122 MINES AND QUARRIES. screen; gyrating screens with motion in a vertical ])lane parallel to their lengths. Roch breaker: See Breaker. Roll crusher: A machine for crushing ore to definite sizes. In roll crushers the ore is broken between two cylinders revolving in opi^osite directions on parallel horizontal axes. Roller mill: A form of crushing machine in which the crushing is done by rollers moving around in a horizontal pan. They are of two general types, radial and centrifugal. In the radial roller mill the axis of the roller is a continuation r undercutting coal in the mine. See, also, Pick machine; Chain cutter machine, etc. Vanner: A machine for sepjarating heavy minerals from lighter by gently shaking or vanning, the mild agitation keeping the par- ticles (jf the lighter mineral in suspension while the particles of the heavier mineral sink to the bottom.

Htaf/isticn. — For censii.s purpo.ses the pro- ductive indu.stries of the country are divided into four broad groups— agriculture, manufactures, mining, and fisheries. It has lieen the endeavor since 1870 to pre- serve the distinction between these groups, but the trend of industrial development has been toward the consolidation of interests so as to bring under one management the production of both the raw material and the finished product. This tendency is especially noticeable in mining and manufacturing, and has caused these industries to overlap at many points, making a statistical separation impossible. The relationship between the two industries is discussed on page 9. It is evident that the difficulties attending a separation are increasing with the development of the resources of the country. If both industries were enumerated at the same time, it would be possible to so word the schedule as to obtain a consistent report covering the entire operations and at the same time make a practi- cable separation of the statistics. On the other hand, mines and quarries are a branch of the extractive industries, which include all those industries dealing in the natural products of the earth and are, in theorj- at least, allied to agriculture, but the statistics of agri- culture for the Twelfth Census do not include any data relating to mines or rjuarries.' The limitations of the statistics for manufactures are not so easily defined. Section 7 of the act of Congress of March .3, 1899, providing for the Twelfth and sub- sequent censuses, confined the inquiry to "manufac- turing and mechanical establishments." If the law had not contained special provision for a mining census, this section would in all probability haA'e been con- strued to cover mines and cjiuarries, as was done in early censuses. In the absence of a direct provision of law, the limitation of the census of manufactures was not fixed arbitrarily, but was determined by the conditions and requirements of those industries which are on the border line between mining and manufacturing. This has resulted in some duplication in the statistics of production. For instance, an establishment engaged in the manufacture of cement that operated a quarry from which it obtained the raw material was reported as a manufactory, but it was also reported in the mining- census as a ({uarry. The two industries being thus interdependent, the duplication incident to the combination of their prod- ucts can be eliminated only by ascertaining the quan- ' Twelfth Census, Report on Agriculture, Part I, pages xiii and xiv. tity and value of tho mining products con.smiied in iniunifacturo. This was attempted at theTwclftli Census by obtainino- from nianufaeturers the cost of materials purchased in a raw state. ^tioxlunj of iiieaKurentenf. — In statistics of mamifac- tures the standard of measurement is limited to the dollar because of the g-reat diversity of products and the impossibility of o))taining a uniform unit of (juan- tity. For similar reasons tho same unit of measure- ment is used in presenting the total for all mining products. The quantity is a. more exact indication of the relative importance of a given product than is its value, and the cpiantity is shown for the majority of the minerals; but the impossibility of applying this standard is found \vhen an iittempt is made to reduce the different units to a uniform basis and give to each its true weight. For instance, there were 35, .567,410 long tons of iron ore, 3(1, 940, 710 long tons of anthra- cite coal, 260,216,844 short tons of bituminous coal, 69,557.715 ounces of gold and silver, 34,291 flasks of quicksilver, and 89,275.302 barrels of petroleuui re- ported as produced in the United States during the year 1902. These various units can not })e reduced to a uni- form Ijasis, and the aggregate value is necessarily used in presenting the total. The value of the annual pro- duction of gold and silver was almost half as great as that of anthracite and bituminous coal, })ut there were nearly ten times as many wage-earners employed in the production of coal as in the production of the precious metals. The changes in value per unit have resulted in a decrease in the total value of certain products, although the quantity has increased, while for others the per- centage of increase in the total value has exceeded that of the total quantity. By the use of the quantity the uncertainties due to fluctuation in prices are elimi- nated. Table 5S, which shows the production and conmiercial value of silver for selected years, as com- puted bv the Director of the Mint, illustrates, for two periods, the increase in quantity accompanied b}^ a de- crease in value, and for three periods, the increase in quantity accompanied by a smaller increase in value.

For three of the periods shown in the above table the percentage of increase in the quantity of silver produced exceeded the increase in commercial value, and for two there was an absolute decrease in value with a small rate of increase in ([uantity. The greatest difference is shown for the period from 1894 to 1902. The production for 1902 showed an increase of 6,00(),0(i(» ounces, or 12.1 per cent over the production of ls94, while the commercial \-alue decreased by §2,0<»7,O00, or 6.4 per cent. There was also a decrease of $3,713,0(10, or 11.2 per cent, in the value reported for 190ji as compared with 1901, although the pro- duction increased by 286,00(1 fine ounces, or flve-tenths of 1 per cent. While in the case of silver the j^roduction has increased more rapidly than the value, the reverse is true for coal, the value having increased more rapidly than the production. This is shown by the following table, giving the quantity, value, and percentage of increase in the production of anthracite and bituminous coal : Table .59.— PRODUCTION OF ANTHRACITE AND BITUMINOUS COAL.' 1891. 1892. 1898. 1899. 1898. 1902. riiffe Short tons. 117,901,238 ' 179,329,071 219,976,267 2.53,741,192 33, 764, 925 219,976,267 301,590,439 81,614,172 J117, 188, 400 207, 666, 381 90,377,981 208, 023, 250 2.56, 094, 234 208, 023, 250 367,032,069 1,59, 008, S19 Per cent of increase.

The per cent of increase in the value of the produc- tion of coal for each of the periods covered l)y the above statement wa,s greatly in excess of the percentage of in- crease in production and in the number of employees engaged, in the industry. The production for 190ii, as compared with 18'JS, increased by 81,014,17^ short tons, or 37.1 pel' cent, while the value increased $1.59, '.H>8, 819, or 76.4 per cent, the average value per ton increasing 27 cents, or 28. i per cent, and the number of employees 116,976, or 29.2 per cent. The increase in value does not convey a correct idea of the importance of the industiy from the standpoint of employment, but there is a close afhnity between the quantity of the product and the number of wage-earners. The production of a mine depends upon the thickness of the vein; the purity of the ore; the ease of working, as influenced, for example, by the necessity for drain- age; the ability and energj? of the superintendent and bosses; and the state of the labor market and the char- acter of the laborers. All of these factors influence the cost of production, whicli also depends upon the price of supj)lies, the freight charges of transportation com- panies, and the character of the financial management. Value of products fur 19iy2. — The value of product reported at the census of 1902 was the value f. o. b. at the mine or quany of all mineral or stone mined dur- ing the 3'ear. A similar value was given for the pro- duction of petroleum, but for natural gas the value reported was the price to the consumer as obtained from the books of the companies. The total value of products for all mines, quarries, and wells amounted to $796,826,117. As explained on pages 9 and 10, in .some instances this value includes products that have been subjected to manufacturing processes carried on at the mine or quarry. It is the amount received ]y the operators of the mines or quarries and should not bo confused with the value of the metallic contents (jf ores, such as retined gold and silver or tine lead, whicli are sometimes classed as a part of the \'alue of the mineral products of the country. The total \alue of the com- mercial mineral production reported by the Ignited States Geological Survey amounted to $1,260,637,415 for the year 1902. The difference between this value and the census value is explained on pages 129 to 131. The value of the products reported at the census of 1902 is shown for each of the difl'erent classes of min- erals, and these classes are also grouped in order to bring together the products of a similar character or of which similar uses are made. In all cases where the quantity of the product could be reported it is pi-e- sented in connection with its value, and the statistics are discussed in detail in the separate reports for each mineral. The salaries, wages, and expenses reported for each mineral cover the d(^velopment work cari'ied on during the year at productive mines, and their sum for some mines necessarily exceeds the value of the products. In the natural gas industiy the expenses incident to distribution are charged to the state in which they^ were incurred, while the ^alue is reported for the state from which the product was obtained. For these and other reasons the expenses should not be considered as indicating the cost of the product, nor the ditt'erence between the total expenses and the value of the product as the profit of mining operations. The statistics of production are discussed in detail in the separate reports for the different minerals and also in the presentation by states. The following statement shows the value of the products for all minerals grouped according to their character oi' uses and the percentage that each group is of the total: Value of jirodiictfi for gronp.i of miiierali find jierceiitar/e ench ig of the total: 1902.

The production for the "metallic" group, which includes copper ore, gold and silver, iron ore, lead and zinc ore, manganese ore, and quicksilver, was valued at $215,453,587, or 27 per cent. The structural mat(>rials, comprising stone, cement, clay, and slate, were valued at $96,370,559, or 12.1 per cent. All other substances obtained from mines and ((uarries were valued at $15,704,600, or 2 per cent of the total. It appears, therefore, that the mineral products of the country are composed very largely of fuels and metallic ores, these two groups forming .S5.9 per cent of tiie total.

While, with a few notalile exceiitioiis, the average values per unit for the minerals included in the above table indicate a general increase in 1902 as compared with 1889, the averages should not be accepted as reflecting the actual conditions. As explained on pages 8 and 9, the products were not reported at the two cen- suses on a uniform basis. The theory of both censuses was evidently to report, as a rule, the crude products, but in a nuni})er of cases re lined or partially refined prod- ucts were necessarily included. It is impossible to deter- mine the exact extent to which the partially manu- factured product has been included in the totals for either census. The quantities and value of coal, iron ore, petroleum, and other minerals for which a crude product is necessarily reported, or of buhrstones, mill- stones, oilstones, cement, and other substances reported in a manufactured or partially manufactured state may be accepted as a basis for computing the average value, although these values are in every instance the value f. o. b. at the mine and include different grades of a general class or group. For instance, different varie- ties of cement and different grades of the same variety are included in the totals fur both censuses; therefore an average price obtained from such a combination has little significance. Where practicable the average value per unit is given in the reports on the se]5arate minerals. By-jirodiictx. — In adopting the classification of min- Ahrasive iiiaterudv iind tin- (juaiitifij (ind ridiii: uf kucIi. erals used by the United States Geological Survey it was necessary to assign to certain classes products ob- tained from mines or quarries reported under other classifications. The class of products included in the totals for each mineral are descriljed in the sepaiate reports and also in the discussion of " classiiication," pages 24 to 35. This method of assigning the jiroducts found the widest application in the group of " abrasive materials." Of the total value — $1,177,711, reported for this group of minerals— $444,539, or 37.7 per cent, represents products obtained from quarries included in other classifications and under which the statistics for employees and wages and expenses are shown. In four of the classes of materials iiududed under abrasives a jjortion of the products was obtained from ([uarries included under other classes of minerals. Of the $6*17,431 reported as the value of grindstones and pulpstones, $403,066, or 60.4 per cent, was obtained from quarries included under the classification of " sand- stones and (juartzites." This value, §4n3,066. should therefore be added to the classification of sandstones and ((uartzites in order to ol)tain a value consistent with the salaries, wages, and other expenses. The foll(i\ving statement shows the (|uantity and value of each class of products included under abrasive ma- terials and also the quantity and value of each class olitained from other classifications: iii(ifrf/(d.s i>I)f FHnM (jlAKItlKS ( I.ASSIEIK TOTAL ABRASIVE MATERIALS.

The municipal (juarries iu Massachu- setts were engaged exclusively in the preparation of road material. There were 7!» natural-gas wells oper- ated by 11 municipalities, the gas, valued at 1205,202, being used in the operation of electric light and power plants. The gas was also used for the illumination of public buildings, streets, and grounds, and iu some instances, was sold to private consumers. Peiiiil /nstitutlons. — The United States Bureau of Labor has made two reports on convict labor.' From the latter of these reports, which was published in July. 1896, it appears that the practice of employing ' Report of the United States Comiiiiissidiier of Labor, 1886, and Bulletin of United States D'-partuient uf Labdr, .July, 18%, convicts in mines and quarries and in the dressing and preparation of stone for building purposes, or for the construction of highways, prevailed in a number of state penitentiaries. The value of such work for the year 189.5 was reported at $1,578,905. Work of this character was also done to a considerable extent Ijy the inmates of penal institutions, where the regulations are less rigorous than in state penitentiaries. The ma- jority of the convicts thus employed were not en- gaged directl^J^ by the state, but were worked under a contract, lease, or other s^'stem, and therefore the value of their work reported to the Bureau of the Cen- sus would be included in the returns of mines and quarries operated by private enterprise and reported under the head of ''contract work." The statistics for the 19mii>es and quarries operated by penal institutions are presented in the following table: Table 03.— MIXES AND IH'AKRIKS OPERATED BY I'EXAL IXSTITl'TIONS: lltOl'.

THE VERIFICATION OF THE MININd CEN.SITS. Statistics of the mineral products of the countiy are collected by the Bureau of the Census, also by tlie United States Geological Survey and by the mine in- spectors and o-eologists of difl'erent states. When the statistics compiled by these various offices relate to the same mineral and cover the same year as that covered by the Census reports there should be a certain degree of harmony in the results, but this is disturbed because various methods are followed in collecting and compil- ing the data, according to the object of the report. The statistics in some of the reports represent a year's pro- Table 05. duction; in others the}' represent the product placed on the market during the 3' ear; in some thej' give the quan- titj^ and value of the crude material; and in others they show the ([uantity and value of the product partly manu- factured or prepared for the market. i'omjiarixon initJi. (reologicol Survey. — The reports of the United States Geological Survey are published yearly and are harmonized with the reports for the pre- ceding year, also with prior Census reports. An agree- ment between the statistics of the Survey and those of the Bureau of the C'ensus was one of the objects of the cooperative work of the two offices in collecting the reports for the mining census of 11MJ2.

By this practice there was assigned to some classifica- tions a production of ores which included several met- als, and in order to compare the Census data with the reports of the Geological Survey, the total production of gold, silver, copper ore, and lead and zinc ore is given in the foregoing ta)>le, irrespective of the class of ore with which thej^ were mined or from which they were obtained. The products, therefore, do not agree with the products shown elsewhere for the same class of minerals. For instance, the copper contents of all ores, as shown by Table 05, amounted to t).39,U33,392 pounds, valued at $71,192,014, but the products of the copper mines, classed as such by the Bureau of the Census, amounted to 11,780,064 short tons of ore, val- ued at $51,178,036. Notwithstanding the above ar- rangement the production of gold as reported bv the Geological Survey exceeds that of the Census report by 627,961 ounces, valued at $12,981,110; and of silver by 1,301,656 ounces, valued at $1,682,950, both exclusive of Alaska; of copper bj' 20,475,252 pounds, valued at $5,376,940. This excess in tlie reports of the Geologi- cal Surve3r is due to the fact that the totals for the Bureau of the Census are based on the reports of the mine operators representing the production of the mines, while those for the Geological Survey are based on the reports of smelters and refineries, and show the amount of refined metal marketed during the year rather than the amount produced by the mines. The value of 1 ton of ore assaying 1 ounce of gold per ton may have been computed, in the settlement between the miner and the smelter, at the rate of $19 per ounce of fine gold contents, from which further deductions were made for treatment and freight, leaving to the miner perhaps not more than $10 net, whereas the value of 1 ounce of refined gold bullion would be reported b}^ the United States Geological Survey as $20.67. The results of both otEces are correct, one aiming to obtain the market value of the refined metal and the other the amount received by the miner for his operations during the year. The production of lead and of zinc, as reported bjr the Bureau of the Census, exceeds that of the Geolog- ical Survey by 68,125 and 370,194 short tons, respec- tively, while the value of these metals as reported b}' the Geological Surve}^ exceeds the value shown in the Census report by $3,958,987 and $5,619,235, respec- tively. This discrepancy is due also to the fact that the Geological Survey reports the quantity and value of the refined product, the crude product reported by the Bureau of the Census being of greater weight but less value. That part of the ditlerence which is due to the inclu- sion of manufactured products )»y the Survey, under the same or similar mining classifications as those of the Bureau of the Census, is illustrated by asphaltum and bituminous rock. The Bureau of the Census re- ports 39,220 short tons less than the Geological Sur- vey; these are valued at $528,320, and are the residual asphaltum product of petroleum refineries, which the Bureau of the Census classifies as the result of manu- facturing processes. The Bureau of the Census report for mineral pigments, crude, is another illustration. The Geological Survey reports instead mineral paints, which are a manufacture, and its statistics are for the manufactured product marketed, the excess over the Bureau of the Census report being 37,570 short tons, valued at $583,447. Graphite affords an illustration of the difference due to reporting the pi'oduction marketed instead of the production mined. The Bureau of the Census values, which are for the production mined, exceed those of the Geological Surve^^ which are for the production marketed, by $45,400. All of the difl'erences between the amounts and values reported b}' the two offices are explained in the foot- notes to Table 65, but another illustration ma^" be given. The Bureau of the Census shows no production of antimony, but the Geological Survej^ reports 3,561 short tons of this metal, valued at $634,506. There was no production of antimon\' from domestic antimo- nial ores during the year 1902, and the entire quantity reported b}- the Geological Survey was obtained from smelting foreign or domestic hard lead ores from rcgulus or metal or from antimonial ores imported. The production, therefore, has no direct connection with the operations at the mine and was omitted from the mining census. In addition to the minerals enumerated in Table 65, the annual reports of the Geological Survey show the quantity and value of the following substances which are, foi- Census purposes, classed as manufactured products, and therefore omitted from the statistics of mining: Aluminum, lu-omine, coke, pig iron, salt, zinc white, and arsenious oxide. The Geological Survey also reports the production of brick clay, glass sand, and mineral waters. Brick clay is omitted from the mining census, as the manufacture of brick, with that of all other clay products, was reported in the census of manufactures. The value of the material was a con- stituent of the value of product, and this material was generally mined by the manufacturer. Glass sand is omitted because most of it is oljtained from sand banks or from river beds, and such production was not con- sidered as forming a part of the mining or quarrying operations of the country. Glass sand, when ol)tained from the crushing of sandstone incident to the quarry- ing of such stone, has been included in the Census report on stone under the classification of "silica sand." Mineral waters are omitted because it is impos- sible to make a complete enumeration of such waters, and there is very little, if any, labor incident to their SUMMARY AND ANALYSIS OF RESULTS. 131 production, the operations consisting- entirel}' in bot- tlinu- and otherwise mailing the product ready for the niarlvet. In order to cover the total production of minerals of all classes, the Geological Survey also includes an "es- timated value of mineral products unspecitied." Begin- ning- with 188'j the value of these miscellaneous miner- als has been placed annually at $1,00(1,000. An estimate of this character was not attempted for the census of 1902, the production being contined to the quantities and values reported by the mine operators. With the exceptions indicated, all of which are due to the differ- ence in the objects of the reports of the two oifices, there is an exact agreement in the production of the diti'erent minerals as compiled by the Geological Survey and the Bureau of the Census. Oomp/iri''0)i with state repoi'tn. — While the state mine inspectors and geologists in a num))er of the states col- lected miscellaneous information concerning different minerals, the only uniform compilation of the i^roduc- tion relates to anthracite and bituminous coal. The quantities of coal, as reported bj^the Bureau of the Cen- sus and b}' the state officials in several of the princijjal producing states are shown in the following table: Table 66. — Yearly production of coal as reported by United Stales Census and state offices.

The production of coal, as reported bj'^ the Bureau of the Census, agrees exactly with the production as re- ported by the Geological Survej^; and from the above table it appears that when the reports of the Bureau of the Census and the state officials cover the same year there is a substantial agreement in the quantities re- ported, the greatest variation being shown for Penn- sylvania, where the production of bituminous coal as reported by the state exceeds that shown ]>y the Bureau of the Census by 371,836 tons. A number of the state reports, however, cover the fiscal year ending June 30, while in one instance, Ohio, the report co\'ers the year ending November 15, and no satisfactory comparison can be made with the Bureau of the Census returns. In addition to statistics of the production of coal the state of Missouri collects information concerning the production of lead and zinc. The production of these metals, as reported by the state office for the year 1902. amounted to 12(;,831 and 234,903 tons, respectively, as compared witli 124,537 and 240,057 tons, respectively, reported ))y the Bureau of the Census. This is a strik- ing agreement in the quantities compiled by two entirelj^ independent offices. The state of Idaho also collects information concerning the production of lead. The production for 1902, as reported hj' the state office, amounted to 119,223,000 pounds, as compared with 208,093.202 pounds reported by the Bureau of the Cen- sus, the census i-eport exceeding that of the state Ity 88,870,202 pounds. The production of lead in Idaho is obtained entirely from silver-bearing lead ores, and the total quantity can not be definitelj' ascertained until the ores have been subjected to .smelting processes. The quantities, therefore, were estimated. This fact, in connection with the fact that the reports for the state do not necessarily apply to the quantities obtained from the ores mined during the census year, probably accounts for the marked difference. The quantity of iron ore produced in the state of New Jersej' during 1902, as reported by the geological survej^ of the state, amounted to 443,728 tons, as compared with 441,879 tons reported by the Bureau of the Census. XX. MINING AND MANUFACTURING. The combination of mining and manufacturing by the use of the .same capital, wages, expenses, etc., has been accentuated by the consolidation of industrial enterprises, and it is impossible, in many instances, to segregate the statistics so as to show the true totals for each branch of industiy. If the statistics for min- ing and manufacturing were to be taken together it would be easy to find a common term for this union, and comparatively simple to show the aggregate figures; but such a combination would not be a compliance with the act of Congress of March 6, 19()2, which provides for mines, mining, quarries, and minerals as a distinct class of cen.sus work. Theoreticall}' a perfect mining census should terminate with the delivery of the ore or crude rock at the mine oi' quarr}^ but in many cases the employees work indiscriminately in both branches of industry and no value is placed on the ore a« it leaves the mine. Where the milling, separating, wash- ing, burning, calcining, or other forms of reduction or manufacture were performed at the mine or quarry, the census of mines for 1902 includes, as a rule, the em- ployees and the expenses involved in the entire work of the establishment. But the absence of uniformity in this respect at prior censuses makes it impossible to prepare satisfactory comparative statistics for a number of the important minerals. The Twelfth Census of manufactures includes in a numl>er of instances the mining and quarrying oper- 132 MINES AND QUARRIES. ations which are incident to such manufacturing- a,s the smelting and retiningof ores, the manufacture of monu- ments, tombstones, etc. The statistics for the two branches of industry are therefore to some extent duplicated. The totals, however, are presented in the following table: Table 07. — Mi/iriiig and manufactures;; 1902 and IfiOO. Number of establishments Salaried officials, clerks, etc.: Number Salaries Wage-earners: Average number Wages Miscellaneous expenses Cost of supplies and materials. 435, 876 $443, 873, 390 .5,903,117 S2, 700,. 537, 970 «l,100,(;80,tV24 S7,4W,S0S,:W.5 Value of product , $13, »:W, 105, 983 Mining, 1902. 38,128 $39,020,552 .581,728 S;ifi9,959,960 $71,771,713 $123,814,967 $796,82(1,417 Manufactures, 1900. 512, 734 397,748 $404,8.52,838 5,321,389 $2, 330,. 578, 010 $1,028,908,911 $7,360,993,418 $13,0:59,279, .566 1 Number of mines, quarries, and wells. The cessation of work in the anthracite coal industrv for a number of months during 1902 tends to reduce the value of the statistics for the mining census as rep- resenting conditions during a normal year, Init with this exception the totals may be accepted as showing the aggregate importance of the two industries during a period of twelve months and the proportion which each contributes to this aggregate. ■ The table indicates that the kindred industries of mining and manufactur- ing, which include the mechanical industries, gave em- ployment, on an average during the year to 6,338,993 persons, and paid §3,14-1:, -411, 360 in salaries and wages. Of this total the salaried officials luimbered -1:35,876, or 6.9 per cent, and the wage-earners .5,903,117, or 93.1 percent. The mining industries contributed 9.8 pei- cent of the number and 13 per cent of the wages and salaries, respectively, and the manufacturing luid me- chanical industries 90.2 and 87 per cent, respectively. Of the ^13,836.10.5,983 reported as the gross \-alue of products, mining contributed .5.8 per cent and manufac- tures 91.2 per cent. In a few of the basic industries it is jDossible to follow the production of the mine to the initiatory stage of its manufacture and to ascertain the (|uantity and value of the product after it has passed through the first manufacturing process; but the comparison of this quan- tity and value with the quantity and value of tlie min- eral is apt to be misleading. The mineral niiitorials consumed in manufactures are necessarily the result of mining processes carried on at a previous date, and often the manufactured product is composed of ditfer- ent minerals and other suljstances, tunwe of whidi are the result of manufactures. For instance, the produc- tion of iron ore for 1902 was 35,567,110 long tons and of pig iron 17,821,307 long tons, indicating that each ton of pig ii'on required al)Out two tons of iron ore, but it is probable that a large proportion of the pig iron was mtuiufactured from iron ore mined during the pre- ceding year ;uid that a considerable proportion of the production mined during 1902 was not used in manu- factures until after the expiration of that year. The production of pig iron consumed not onl^' all of the iron ore, but a large proportion of the 39,601,007 short tons of coal from which 25,101,730 short tons of coke wore produced, practically all being emplo^^ed in blast fur- naces. The industry also consumed the 11,878,675 long tons of limestone used for fluxing purposes, and large quantities of coal as fuel. The raw materials reported at the Twelfth Census as consumed in manufactures amounted to $2,389,110,912. Of this total, $1,910,727,018, or 81.2 per cent, were obtained from the farm; .^]1S,8U3,115, or 5 per cent, from the forest; 1319,975,108, or 13.1 per cent, from the mine; and $9,635,671, or four-tenths of 1 pe:' cent, from the sea.^ These amounts represent the materials consumed during the year ending Maj^ 31, 1900, while the products for the mines and quarries, which prod- ucts were valued at $79(1,826,117, were for the calendar year ending December 31, 1902. The two amounts, therefore, are not comparable. This lack of compar- ability is due not only to the fact that the two reports cover difl'erent periods, but also to the fact that the value of the products of the mines and quarries includes in manv instances the value of finished prod- ucts readj' for consumption. For instance, the amount for the product of mines and quarries includes cement to the value of $24, 268, ,838; finished slate products to the value of $5,696,051; buhrstones and millstones and other finished abrasives to the value of $841,207. It also includes considerable proportions of the products of marble, sandstones and quartzites, siliceous crvstal- line rocks, anthracite coal, natural gas, and other minerals whidi were either sold at the quarry as finished products or consumed in other establishnunits than those engaged in manufactures. Ikit the cost of the materials o))tained from the mine and consumed in manufactures does not include the cost of coal, natural gas, or petroleum used as fuel in manufactures. Accord- ing to the Twelfth Census, all kinds of fuel consumed in manufacturing esta))li,shments cost $2(15,320,632, and there was also paid $10,98(),353 for the rent of power and heat. A large proportion of this cost repre- sents the products of mines. AVhile all manufactures depend upon the production of mines either for raw materials or machinery, the production of metals is the most striking illustration of this interdependence. Of the \'iirious metals, iron is the most important, and it is possible to show its pro- duction in connection with the production of the min- erals upon which it depends.

The production of coke increased 147.() per cent, and of limestone used as lluxing material 92.1 per cent. The produrtion of iron and steel was valued at $430,954,348 at the census of 1890, and at §803,968,273 at the census of 190t», an increase of $373,013,926, or 86.6 per cent. These industries are dependent upon the production of iron ore, and an increase in its production would necessarily be followed by a corresponding increase in their manufactures. When the ore and fuel both exist in the same local- ity the corresponding manufactures naturally develop locally; this is well illustrated by the growth of iron manufactures in Alabama during the last two decades. Whereas at the census of IHSO Alabama ranked fifth in coke and eighteenth in iron and steel, in 1900 the state was second in coke production and sixth in iron and steel manufactures. The rapid growth of manu- facturing industries is due to the utilization of the state's rich mineral resources, which were neglected in the earlier years of the century. The state po.ssesses within its borders all the requisites for iron manufac- ture — iron ore, coking coal, and limestone for Hux. The same is true of Colorado, which has developed greatlv in coal and iron and the attendant manu- facturing industries during the last decade. The fol- lowing table shows the interdependent growth of the coal and iron and the allied manufactures in these states: Table GS.-IXTERDEPENDENT GROWTH IX THE MININ(t AXD MAXUFACTURES OF COAL AXD IROX IX ALABAMA AXD COLORADO: 1902 AXD 18S9.

While a considerable portion of the bituminous coal was consumed in the manufacture of coke, large quan- tities were used as fuel in manufactures generally, and also in other industries; therefore, the increase in its production is not necessarily accompanied by a cor- responding increase in the production of iron. It is also probable that a portion of the coal, coke, and limestone produced in these states was shipped out of the state for consumption in manufactures in other sec- tions of the countrj'. During the period of thirteen years covered by this table the quantity of iron ore, coal, coke, and tluxing material more than doubled in both states, and the value of iron and steel and foundry products indicates that there has lieen a very large in- crease in the metal industries, though the statistics for them cover a period of only ten years. Economies of production in manufactures demand the proximity of raw material, and also of a market for the ' Mineral Resources of the United States," 1902. linished product, or convenient transportation facilities for either or both. In the endeavor to secure the bene- fits incident to the greatest number of these conditions, factories have been located in difl'erent sections of the country, according to the relative advantages to be ob- tained from proximity to materials, market, or trans- portation facilities. This localization of industries has been in some instances a gradual growth, as in the case of the manufactures in the New England states, and in others a rapid development, following the discovery of exceptional natural advantages, such as the coal and iron fields of western Pennsylvania and of Alabama. Consider-ing the census of manufactures of 1900 and the mining census of 1902 as comparable. Table 69 shows the total value and the proportion of the prod- ucts of the mines and manufactures in the different geographic divisions of the country. 134 MINES AND QUARRIES.

The North Atlantic .states produced (jiily 2.1 per cent of the ores, but the value of fuel aniounted to 45.5 per cent and of manufactures to more than half of the total for the United States, indicating a concentration of manufactures to obtain the advantages incident to a liberal supply of fuel and a ready market. The North Central states produced ore valued at $91,216,846, or 42.-3 per cent of the total value of the ores, but the value of the fuels and manufactured products formed onl\' 28.1 per cent of the total value for the United States. This tends to show that the ores were not used where the}' were mined, and that the mine operators were forced to take advantage of the transportation facilities to supply materials for the factories in the North Atlantic states. Of the ores obtained in these states, a value of $68,932,294 repre- sented iron and copper from the mines of northern Michigan and Minnesota. The largest part of the freight transportation on the Great Lakes is on account of these mines. Transportation facilities here play an important part, the iron ores of Lake Superior being transported to the south Lake ports and to the centers of cheap fuel and iron consumption. The value, $110,823,676, or 51.4 per cent of the total shown for the ores in the Western states, was compo.sed very largely of tiie value of precious metals and copper, these minerals forming 67.9 and 29.1 per cent, respectively, of the total for the geographic divi- sion. The refined metal obtained from both of these minerals was sent elsewhere for manufacture. The freight movement on the Great Lakes for 1902, as shown by the receipts at the Lake ports, aggregated 54,074,729 tons.^ Of this, iron ore and mineral tonnage (not including coal) was 27,898,424 tons and coal 8,256,117 tons, making a total of 36,154,541 tons for mine products. This was 66.9 per cent of all freight. 1 Department of Commerce and Lalior, Bureau of Statistics, "Monthly Summary of Commerce and Finance of the United States," November i to February 28, 1902-3, page 1797. The iron ore production of the upper Lake district, Michigan, Minnesota, and Wisconsin, was 27,056,861 tons, di.striljuted as follows: Michigan, 11,135,216 tons; Minnesota, 15,137,650 tons; and Wisconsin, 783,996 tons. This was 76.1 per cent of the iron ore produc- tion of the United States. The copper shipments, though of great value, do not constitute a large tonnage item of the Lake traffic, as most of the ore is smelted at the mines and only the copper shipped. The copper product of northern Michigan for 19(,)2 was 171,102,065 pounds, or 85,551 tons, but a large portion of this prod- uct was shipped, as mineral to be smelted at Buffalo. The total copper shipments on the Great Lakes were 140,5(.)9 tons; this tonnage includes shipments of copper from the head of Lake Superior received from the West. The movement of iron ore on the Great Lakes is shown by the following table: Table 70. — Morement of iron ore on the Great Lake.i: 1902. SHIRMENTS. RECEIPTS. Ports. Tons, Ports. Tons.

EXPORTS AND IMPORTS OF >riNERALS. ErjM'nis. — While the development of the exi)oi-t trade has been one of the leading features of industrial prog- ress in the United States, the vast majority of mineral products of the country are subjected to manufacturing- processes before they are sent out of the country, and therefore the products of the mines and ((uavries, as re- ported to the Census, form a very small proportion of the exports. The total exports of domestic merchan- dise for 1903, exclusive of gold and silver and phos- phate rock, amounted to i?l, 349, 493, 266, and the ex- ports of the products of mines, including crude min- eral oils, amounted to $33,327,517, or only 2.5 per cent. The coining value of gold and the commercial value of silver produced during 1902, as based on the Census re- ports, and the production of gold and silver in Alaska, as estimated by the Director of the Mint, amounted to $102,695,557. Exclusive of coin the coining \-alue of gold and the commercial value of silver exported was §70,119,816, the exports amounting to 6S.6 per cent of the production. The classification followed by the Bureau of Statistics in compiling the statistics of ex- ports does not correspond exactly with the classification of minerals adopted for the census of 1902. Their figures, however, may be used for the purpose c)f in- dicating the approximate amount of crude minerals ex- ported. The following table presents the value of the exports of domestic merchandise, exclusive of gold and silver and phosphate rock, and the ratio of the exports of the products of mines to the total exports for each year from 1889 to 1902: Table 72. — Exports of domestic merchandise and products of mines, excliisire of gold and silver and phosphate rod:: 1889 to 1902.

SUMMARY AND ANALYSIS OF RESULTS. 137 With the exception of nickel and phosphate rock, the (|uantities exported formed only a small proportion of the mining- products of the country. The value of the exports of nickel and phosphate rock in llM):i appar- ently exceeded the value of the total production of those minerals by |2, 1-1:7,458. It is probable, therefore, that the elassihcation adoi)ted by the Bureau of Statistics included partially manufactured products, or other substances not included in the mining- census, else the exports were composed in part of products mined dur- ing- prior years. The value of anthracite and l)ituminous coal formed more than a third of the value of the exports of the mining- products in 18SI) and in each year since. The $20,765,461 reported as the value of the coal exported in 1902 represents 6,971.18-1 tons; of this amount 4,732,185 tons, valued at §14,281,425, or 67.9 per cent of the quantity and 68.8 per cent of the value, were exported to Quebec. Ontario, Manitoba, etc. Crude mineral oil was the next most important min- eral product exported. There were 133,536,800 gal- lons of crude mineral oil exported during the year ending June 30, l'.Hi2, valued at $6,0S4,818. Of this total 89,733,032 gallons, valued at $4,272,144, or t;7.2 per cent of the total quantity and 70.2 per cent of the value, were consigned to France; 10.s44,'.tl3 gal- lons, valued at §550, < 194, were exported to Mexico; and 10,132,815 gallons, valued at $4'.)7,i)6o, to Spain: leaving only 22,826,<»4() gallons, valued at $764,920, or 12.6 per cent, as the exports to all other countries. Crude phosphate ranked third among the exports of mining products. The quantity exported for 1902 amounted to 747,672 tons, valued at $5,888,595. Of this total 372,035 tons, valued at $3,133,477, or 49.8 per cent of the quantity and 53.2 per cent of the ^'aluo, were exported to Ihe United Kingdom and Germany, and 375,637 tons, valued at $2,755,118, were exported to other countries. There were 25,076 tons of copper ore exported, valued at $2,601,697; 13,875 tons, valued at $1,895,586, were consigned to the United Kingdom; and 11,139 tons, valued at $699,677, to Mexico, while only 62 tons, valued at $6,434, were shipped to other countries. Imjjo/'fs.— The methods used in compiling the statis- tics of imports are also at variance with those followed by the census, and there are comparatively few products for which a satisfactory comparison of the imports and the production can be made, but the statistics for such products are presented in Table 74.

Asbestos of suitable quality unci in sufficient (juantitics to supply the demand has not been uncovered in this country. Ai<2>]ialtuiii and liituniiiiinis rod'. — While there has been a growing increase in the production of asphaltuni and Intuniinous rock in the United States, the value of the imports for consumption for r.H)2 exceeded the value of the domestic production by ii^ii55,93(». The domestic production was crude material, and it is probable that the imports were of a more highly finished character. The material is obtained in an almost pure form from Pitch Lake, in the island of Trinidad, where the cost of production is reduced to a miniumni. The (juantity imported from this source during the year ending June 30, 1903, was valued at ^329,819. The asphaltuni imported from Barbados possesses peculiar qualities which make it especially adaptable for the manufacture of varnishes and the insulation of electric cables. Chrome ore. — Practicalh' all of the chrome ore con- sumed in the United States was imported. The depos- its in the United States are not conveniently located for development and can not compete with the low price of the foreign ore. Corundum and emery. — The value of ttie imports of corunclum and emery was almost twice as great as the value of the domestic production. The excess of the imports over the production was due chieflj' to the fact that the largest domestic deposits are not convenient!}- located for transportation facilities and can not compete with the large deposits of Canadian corundum that can be more conveniently worked; or the production of Turkish emerj', which is produced at a considerably lower cost and imported into the United States as bal- last. Artificial corundum, moi'eover, is also produced in large quantities and will undoubtedly affect the pro- duction of the natural material. Graphite. — While graphite has been developed in a number of different localities throughout the United States, the production still falls far shoit of the demand, which has increased with the development of the mechanical and electrical industries. Graphite is also being successfully produced b}- artificial means. The imports, however, are still man}- times in excess of the domestic production. Lifiisoriideartli., tripoU, and j'"-"!^'-'-- — The value of the imports of these minerals exceeded the domestic production b}' $6,380. This increase was due entirelv to the imports of pumice, for this mineral has been found and (piarried in the United States in compara- tively insignificant (piantities. The imports were ob- tained almost entirely fi'om the island of Lipari, north of Sicily, and were shipped largely as ballast. Mic/ne.nte. — The entire domestic production of magne- site was obtained fi-om mines in the state of California, which apparently are not able t(j supply the market. No other deposits i[p])eai- to have been discovered. The imports were obtained almost entirely from Greece and Austria. Alica. — While this mineral is found in a number of the states and exists in considerable quantities in difl'er- ent localities, the individual deposits have not been developed to a great extent, and the quality is inferior to that of the impoi'ted variety which is obtained largely from Canada and India. The good variety of mica obtained from the deposits in India and the cheap labor there enables it to be produced and delivered in the United States in sufficient quantities to almost entirel}' supply the market. Ntel'el and rohalt. — Practically all of the nickel and cobalt consumed in the United States is ol:)tained from Canada, where the deposits are extensive and cheaply mined. Both minerals have been found and mined in various localities in the United States, sometimes in connection with lead ore, but thej- have not been pro- duced in quantities sufficient to suppl}' the market, because, in part, of the moderate price which has pre- vailed for nickel. StdjyJnir and jujrite. — The excess of the imports over the production of sulphur is not due apparently to its scarcit}' in the United States, but to the immense de- posits of pure sulphur found in Sicilj', which are worked by cheap labor. The impoi'ts of pyrite more than doubled the production. Tungsten. — The imports of this mineral exceeded the comparatively small production by only $1,071. The domestic production has been obtained largely in con- nection with other minerals. Of the other minerals enumerated in Table 74 the following show the largest amounts imported during the j'ear 1902, the minerals being considered in the order in which they appear in the table. Cement. — The production of cement reported by the census is confined to the manufacture of cement at and in connection with the operation of limestone quarries. The total production for 1902, as reported ))_y the United States Geological Survey, was valued at §25,31)6,380. The imports, therefore, formed a comparatively small percentage of the total consumption. There w^ere 123,81:1:. 160 pounds of Roman, Portland, and other hydraulic cement imported during the year ending June 30, 1902, and these were valued at $1,178,152. Of these imports 227,056,720 pounds, valued at $831,555, came from Germany; all other countries sent 196,787,110 pounds, or 16.1 per cent, of the quantity, valued at $61:3,897, or 13.6 per cent of the total. 6'A///.— As shown by Table 71, the value of the clay imported for consumption was more than half as great as the value of the domestic production. Conmion blue clay, used for the maiuifacture of crucil.)les, was obtained very largely from Germany. The imports from that country for the year ending June 30. 1902, were valued at $59,192, as compared with $13,603 re- SUMMARY AND ANALYSIS OF IlESULTS. 139 poi-ted for all other countries. Other clay, iiicliuliiig- China cla^-, or kaolin, came largely from the ITuitod Kingdom and Germany, the impt)rts from these coun- tries amounting to $1,1:^2,6^7, or 9-J.-J: per cent of the total for other clay. Coal. — While the imports of coal form a very small proportion of tiie consumption, nevertheless considera- ble quantities of hituminous coal were imported during the year 1902, the imports ))eing stinuilated to some extent by the shortage in the production of anthracite coal. The impt)rts from British Columbia, Nova Sco- tia, and New Brunswick for the year ending June 30 were valued at $3,901,52(3, forming 73.5 per cent of the total imports. Including anthracite the imports from all other countries amounted to $1,407,882, or 26.5 per cent of the total. Copper. — The imports for consumption of copper during the calendar year 1902 were valued at $20,537,- 349, the amount being about one-third as great as the production; this mineral is imported largely from Mexico. The imports from that country for the year ending June 30, 1902, were valued at $9,934,097, or 70.9 per cent of all copper imported. Gold and silver. — Gold and silver ore and ))ullion is the most important class of imports, the amount — $55,- 688,883— reported for 1902 constituting 70.7 per cent of the total I'or the principal minerals imported, as shown by Table 74. Of this aggregate the value of gold was $32,5.S2,221, oi' 41.4 pel- cent, and the value of silver was $23,106,66^!, or 29.3 per cent. Of the silver ap- proximatel}' 85 per cent was imported from Mexico. Of the gold about 30 per cent was obtained from Que- bec, Ontario, etc., and about 27 per cent from Mexico. Iran iiri'. — ^I'he imports for consumption of iron ore during the calendar year 1902 were \'alued at $2,558,023. Of the imports for the year ending June 30 iron ore valued at $1,109,205, or 46.9 per cent, was obtained from Cuba; a value of $677,131, or 28.7 per cent, from Quebec, Ontario, Manitoba, etc., and $406,662, or 17.2 per cent, from Spain. Lead and zinc. — The imports of lead ores came almost entireh' from Mexico and British Columbia, the amount received from these countries for the year ending Jime 30, 1902, being valued at $4,401,390, or 97.9 per cent of the total. The value of the minerals imported during 1902 was more than twice as great as the value of the exports of similar products. In a luimber of instances the imports bear an important relationship to the consumption, and the statistics are worthy of more detailed consideration. To assist in such an analysis Table 75 is presented, which gives the value of all the minerals or mineral products, as classified by the Bureau of Statistics, that have been imported for consumption each year from lss!( to 19(12. Some of them are not included in the preceding comparative table. 140 MINES AND QUARRIES. Table 75.— IMPORTS FOR [From reports of the Bureau of Statistics, MINERAL.

ELECTRICITY IN MINING. Bv Thomas Commerford Martin. The mining- industry to-day constitutes one of the most important tields for the appliration of electric current. There is hardily a country in the world and hardly an}' department of mining- in -svhich electrical appliances are not employed, and in many instances the installation and equipment arc of a most extensive character. Indeed, the subject has become so important as to create a literature and a technology of its own. for many of the problems involved are such as do not arise in connection with other work. Hence a brief technical review of the situation can not but prove of interest, especially as the whole tendency of the time is to develop mining industries along- electrical lines, and in fact to employ electricity continuously from the verj' first contact with the ore to the stage at which the finished product is ready for the market. It is pro- posed, however, to limit the present treatment of the subject to electric mining, as both electro-metallurgy and electro-chemistry are distinct fields of technical work, dealing with manufactured material rather than with the cruder and more primitive processes of win- ning- the minerals from the soil. In its early stages electric lighting- was applied to mine work, and this de- velopment was followed by the use of electric loco- motives for traction as a substitute for human or brute power. Of late 3'ears the electric motor has been util- ized for all classes of work — drilling, coal cutting, hoisting, pumping, ventilating, etc. The use of electric explosives has long been familiar to every miner, and more recentl.y the telephone has become a familiar adjunct for purposes of interconmiunication. In the United States, as elsewhere, the introduction of electrical mining apparatus has l)een greatly stimu- lated of late years by the high degree of perfection attained in the art of power transmission. A great many mines and mining camps in regions where fuel was either very costly or difficult to obtain have been brought within the range of profitable working through the utilization of some distant waterpower. The sin- gle and polyphase alternating current, with its flexibil- ity and high range of pressure, has made it possible to transmit power from water courses across valleys and over mountain ranges for scores of miles, so that to-day large areas, which but for the assistance of electricity would have remained neglected, because unavailable, are being worked. The profitableness of American mines and the sources of national wealth have thus been enorraouslj^ increased. The practical use of electricitj^ involves a great many questions, of the nature of which some idea may be formed from the report recently issued in England by a departmental committee appointed b}' the British Home Secretary to consider and report on the subject. As the result of its investigation the committee laid down four general principles which, it considered, -should govern the appointment of electrically equipped mines. These points may be summed up as follows: 1. Tlie electric plant should ahvaj's lie treated as a source of potential danger. 2. The plant should be of thoroughly good quality and so de- signed as to insure immunity from danger by shock (jr fire, and |ieriodical tests should be made to ascertain that this state of effi- ciency is being maintained. 3. All the electrical apparatus should Ije under the charge of a competent person. 4. All electrical apparatus which might be used where there was a possibility of danger arising from the presence of mine gas should be inclosed so as to prevent such gas from being fired by the spark- ing of the aj^paratus, and when any machine is working every pre- caution should be taken to detect the existence of danger, and on the presence of gas being noticed such machinery should be imme- diately stopped. Some of these points seem obvious, yet they have frequently been disregarded. With regard to the first and second, the committee pointed out the fact that under the peculiar conditions existing in mines no abso- lutely safe limit of voltage or of pressure of current could be stated. The conmiittee decided, however, on grounds already recognized in German}' that, provided all reasonable safeguards were adopted, a fairly high pressure had advantages, even from the point of view of safety, over a uniformlj' low pressure. The stand- ard adopted by the board of trade as to voltage in con- sumption circuits is, therefore, 050 volts. Under certain conciitions voltages as high as 3,000 volts are available for transmission purposes. (145^ 30223—04- -10 146 MINES AND QUARRIES. As to the working of electric coal cutting machinerj' in places subject to fire damp, the eonmiittee decided, largely as a result of experiments made, that it was necessary to inclose the entire motor in a tiame-tight cover. The committee adopted the view that all per- mitted explosives should be fired by electricity, and that the armored sheath or covering of all protected cable should be connected to "earth" — i. e., grounded. Table 1 shows the number of mines in the United States reported as owning or renting electric power in 1902, together with the horsepower reported, for each group of minerals.

By far the larger proportion of these — namely, 088, with a total of i;3t»,404 horsepower — operated their own plants. There were 1.31 mines, with a total of 23,556 horsepower, which rented power, l)ut of these mines 17 owned power also. It will be gath- ered from these figures that the 130,4'..)4 horsepower, even if it represents the total current-generating capac- ity, shows a considerable application of electric power; but it should probably be doubled in order to ascertain the capacity of motors installed and using such current. It is a fact well known in electrical plants that motor capacity far beyond the actual current capacity of the generating plant can be in.stallcd, for the reason that the consumption of curi'cnt is varia})le and intermit- tent, it being higlily improbable that all the consum- ing apparatus will take full current from the lines at the same time. It is assumable, however, although the fact is not bi-ought out at ail in the table, that in a great many instances these plants furnish also con- siderable current for lighting purposes. With regard to the rented power, it is probable that it is employed almost altogether to drive motors, a very .small propor- tion of it representing electric lighting. Mines in which the operations are so small as not to necessitate the installation of a separate plant are, it is assumed, operated largely by single .shifts or during daylight hours; so that while some lighting would be needed, the consumption of current would be quite small in proportion to the consumption for hoists, pumps, and other motor-driven mechanism. It will be noted that four-fifths of the electric power reported was concentrated in three industries — coal mining, cement working, and the gold and silver in- dustiy. By far the largest item is that of bituminous coal mining, such mines, numbering 309, reporting electric power with a total of 68,139 horsepower; and these figures must be supplemented b}' those for anthra- cite coal mining, with 17 plants, reporting 5,755 horse- power. It will be seen that those two groups alone represent nearly one-half of the total horsepower. The figures for gold and silver are combined, and the table shows 292 plants reporting, with a total of 46, 472. horse- power. The other category is that of cement mining. There were 31 cement mines reporting electric power, with a total of 20,862 horsepower. It will be observed that these various mines differ considerabls' as to the magnitude of installation. In the gold and silver mines the plants have an average capacity of about 160 horsepower; in the coal mines the average capacity is 227 horsepower; in the cement mine works the average capacity is greater than for any other kind of mines — about 675 horsepower. The other items in the table, while interesting, do not call for anj' partit-ular comment. Poii\r (ji'iieriition mid transiiiiKS/nii. — Electric current for mining purposes is usually obtained in one of two ways, depending somewhat upon the nature of the mine in the first place, and secondly upon the environ- ment. In coal mining regions it is natural that each mine should draw upon its own fuel resources for power, the plant being stationed at the pit mouth; but even in such cases, where there is a group of mines it is some- times found con\'enient to concentrate the power-gen- erating apparatus, transmitting the currentto a distance. This has been done in an even more comprehensive way in western mining fields, one steam plant which utilizes coal delivering its energy to mines no less than 26 miles distant, in districts where waterpower is not available. Where the generating plant is at the mouth of the mine it is customary to employ apparatus producing low tension direct current; but where longer distances are involved the alternating current has l)een resorted to, in the same manner as in central electric lighting and railway plants. The current is generated at high poten- tial by polyphase dynamos and transmitted to substa- IM >^ f^ ^DFSabla'f.Hf'r' CentervjUe P.Hifl French Creek ' I /,>,^' "TS -^M \ ^ (iriillcji Nf vadal P Ji(^.i^- ^ J « \ ,„ \ J\\ '^ \ Colusa JcV ColusiiV* ( -V, SB \ / ' \' '\ rri OV';-^^ Oralloii)^ ^- _J^Veroiiii I -^ — ^' / -j/tiusevilli L J arto^ Clzijtrf *., /ov IVooiilaiid j MerritJsW ^(Ml .es» fPlaleriilk Folsom.

ELECTRICITY IN MINING. 147 tions, whei-e it is lowered in pressure and converted into direet current for use. One of the first plants of this kind for a mine haulage system was installed at Ehrenfeld, Pa. The haulage in this mine was accomplished by rope driving and mules until the main heading, which should eventual Ijr extend 5 miles underground, was nearly 2 miles long. This method was then replaced hy an electric system em- bodying the generation of a 8-phase, ^5-eycle, 5,()<»0- volt alternating current near the pit mouth. This cur- rent is transmitted by insulated cables to a substation in the mine itself, near the center of the actual operations and about !l,000 feet from the power house. Through the intervention of static transformers and a rotary con- verter, direct current at 275 volts is then delivered to the haulage circuits. In the Tug River field, near Welch, W. Va., is an- other plant of the same kind by which three mines are operated, alternating current induction motoi's being- employed for driving- coal crushers and conveyors and direct current for the other mine operations. An interesting variation of this plan is that embodied in the plant constructed for the Raton Coal and Coke Company, at Blossbiirg, N. Mex. When built, in 1S97, the coke plant included some seventy-tive 3-foot ovens, in double banks. In the center was erected a large liattery of boilers, to which the waste gases from the coal are conducted through central flues; the gas thus made available is emploj-ed to drive gas engines and dj'namos furnishing power for the hauling plant both inside and outside of tlie mine. About a mile and a half from the coke ovens is situated the washing and crushing plant, with a capacity of 800 tons in ten hours. All the machinery from tipple to mine opening is driven by electric motors, a trolley line with electric locomo- tives bringing the pit cars from the main entry to the tipple. This idea of the utilization of waste gas in coke lields and blast furnaces has of late occupied consider- able thought and attention on the part of mechanical and mining engineers, and important developments are resulting from the emploj-ment of electricitj- as a means of lessening waste. In most mining districts, however, the work is inter- mittent, machinery is widely scattered in places dithcult of access, fuel is expensive, and the economical use of steam is not possible. Compressed air, as a means of transmitting- power, is handicapped b}' loss in the com- pressor and the piping, and is limited to short distances and to the operation of apparatus requiring power regardless of cost. In this connection, reference ma^^ be made to the tests reported by Mr. Lewis Searing, in 1S96, with electricitjr and compressed air, in a mine situated at Rouse, Colo., at an altitude of (),()00 feet. The actual results obtained with the two plants show that the work of pvimping, whit-h in the case of com- pressed air required 312 horsepower and 8 boilers, could be done by electricity with but 50 horsepower and 1 boiler. This, of course, is an extreme case, but it indicates the difticulties attendant upon the use of compressed air at such altitudes. Under the modern conditions of power transmission from waterfalls, etc., electricity has shown itself to be largely independent of distances, so that, as was pointed out ))y Ml-. F. O. Blackwell, before the American Insti- tute of Mining Engineers, in February, 1903, a given amount of power can be delivered either 528 feet away, at KlO volts, or 50 miles away at 50,000 volts, with the same total amount of copper per horsepower and exactlj' the same loss of power in the transmission circuit. With proper choice of potential and system, this loss need not exceed 10 per cent, even when the current is carried as far as 150 miles. iSo much has been done in the matter of power trans- mission for mining purposes that it is diiEcult to pick out any specific case as thoroughly typical. But it would be hard to find an instance more notable than that of the Standard and Baj' Counties Power Compa- nies, in California. These, consolidating other sj-stems, have a remarkable network of circuits of which one of the largest begins at Colgate, in the foothills of the Sierras, on the North Yuba river, a second at Folsom City, a thir miles. The tying in at Oakland thus gives a trans- mission circuit of 232 miles from the latest plant at De Sabla, beyond Colgate, around San Francisco baj^ and through San Jose to San Francisco. Over the network thus represented, which embraces no fewer than 16 counties, within whose borders lie one-half of the popu- lation and three-fourths of the total assessed valuation of property of the state, several thousand horsepower is delivered daily. Alternating current is distributed to substations at pressures of 40,000 to 60,000 volts, and there manipulated and i-ectitied for delivery to estab- lishments engaged in a variety of industries, including a large number of mining plants. The Bay Counties system is in fact an outcome of earlier mining enterprises, one of which was under- taken for Nevada county to supply the mines there with power. In like manner the Standard system is an outgrowth of work started thirty years ago by the Blue Lakes Water Company, when a ditch system con- siderably more than 80 miles in length was constructed for the purpose of furnishing water to the mines in Amador county. For a long period this company was very prosperous, but with the decline of mining in that section of the mother lode and the complete aban- donnn'iit of hydraulic mining the property became much less profitable. At this stage it was taken up again ))y Prince Poniatowski, to be developed for the purpose of distributing electric power to mines and thus lessening the cost of their operation. 148 MINES AND QUARRIES. The plant at Colgate had an initial equipment of 15,0(M» horsepower in 3-pha,se alternating-ciii'rent dynamos, situated in a power house at the foot of a hill 1,500 feet high. Water for driving the turbines is brought to this plant through a timber flume over 7 miles long- draining 500 miles of watershed, and witli a capacity of 33,000 cubic feet of water per minute. This water, re- ceived in the reservoir near the crest of the hill, falls with TOO-foot head upon the turbines under a pressure of 304 pounds jier square inch. The current from the gehel'ators is delivered at a pressure of ^,400 volts to step-up transformers, which put it on the circuit at a pressure of 40,000 to 00,000 volts. These transmission circuits, each of three wires, are carried on lofty poles of Oregon cedar and are in duplicate, one set consisting of hard-drawn copper wire and the other of aluminum. At the Karquines straits the circuit crosses in one span of 4,448 feet of sagging steel cable 200 feet above tide water and held up by enormous steel lattice towei's. The system has in operation about 700 miles of line at 50,000 volts, 70 miles at 40,0(i0, and a great many miles at 23,000, 16,000, 10,(»0(.), and 5,0o0 volts. It is stated with regard to the efficiency of the transmission that 1,000 horsepower at the Colgate water wheels nets roughh^ about 750 available horsepower in San Fran- cisco, 222 miles away, the loss being 6 per cent in the generators, 2 per cent in the step-up transformers, 2 per cent in the step-down transformers, and 15 per cent in line losses, etc. This does not represent the general efficiencv of the whole system, because there are a great many branches and tap circuits, to mines, etc., but it is understood that the results attained by the system as a whole are such as to have stimulated the construction of similar plants, one of which has been erected for mining purposes, with American apparatus, at the Cauvery Falls, Madras, India. Such a plant as this is a sufficient exempliticatiori of the possibilities involved in electrical power transmission for mining purposes, utilizing the energy of falling water. Such transmission will again be referred to inci- dentalh' in connection with certain utilizations, but before closing this section reference should lie made to the important work undertaken for electric power dis- tribution from coal mines in England and Wahis, a country with cheap coal but \-ery little available water- power. Since r.tOl tliere have been established a luim- ber of plants and companies for long distance trans- mission, based upon coal mining and intended larg(d>' for mining purposes. Ir) fact, one of these, at New- castle-upon-Tyne, co\'ering a sti'ip of territory in the vicinity of tin? Tyne i'i\'er, Ijegan on a small scale in 1898; it was greatly enlaig-e(l inlH(»2. One in southei'n Wales co\(,'rs the coal and iron field of tiiat section. One in Lancashire^ covers the coal field of that county, extending on the west to the Irish sea. One in the county of Durham covers 25n squai-c miles of coal territory, extending to the North sea. One in adjacent territory, including the Cleveland iron field in York- shire, covers an area of 820 square miles, while one in southern Yorkshire covers 1,800 square miles. One in the counties of Leicestei'shire and Warwickshire covers l,69y square miles, while one in the county of Cornwall, particularly designed to revive the decaying mining industries of that famous old tin region, covers 1,356 square miles. Another system in Derbyshire and Nottinghamshire deals with an area of 1,500 square miles. A few details may l)e given as illustrative of the extensiveness of the English enterprises, some of which are now actually in operation. Within the area of Der- byshire and Nottinghamshire — containing some of the largest coal fields in the world — are electric power com- panies with a capital of about $9,000,000. There are within it 564 individual works of importance, of which 159 are coal pits, and no fewer than 400 firms, repre- senting a capital of al)Out §100,000,000, supported the enabling bill when passing through Parliament. It was proposed at first to have for this area four large gener- ating stations, with a total cai^acity of 60,000 horse- power, but in 1903 the applications for power so far exceeded the estimates that it was even then proposed to enlarge at least two of the generating stations. While in the individual mines and mining enterprises the lar- gest individual dynamo or engine unit is 200 horsepower, the smallest unit for this system is one of 3,000 horse- power. The numerous collieries in the region are counted upon as the principal customers for this sup- ply of current, and. taking as a basis the fact that about 7 per cent of the coal mined is consumed in obtaining the 93 per cent sold, it is estimated that Ijy the use of electricity in mines under these new conditions, in con- nection with the various purposes of hoisting, traction, pumping, ventilating, etc., 10,000,000 tons of coal can be saved annually. The operations of the power com- panies at Newcastle-upon-Tyne have shown that power can be deli\'ered to large works in the vicinity at a rate slightly exceeding 2 cents per kilowatt-hour unit— that is, at a rate of about 1;^ cents per horsepower per hour. Elsewhere in England and Wales the collieries them- selves ha\-e demonstrated the efliciency of electric power ti-ansmissioti, as, for example, in the case of the Trede- gar Iron and Coal Company, in Monmouthshire, Wales, whose plant is the largest of the kind for individual mining enterprise in P^ngland or Wales. Two 300- horsepower engines direct connected to 3-phase gener- ators at one set of mines supply current over pole line transmission circuits at 2,oo0 volts to other mines about a mile and a quarter away. Both electric haulage and electi'ic punij)ing are features of this installation, and at the time of the last rei)ort it was noted that, although 1 ■ ' n these mines Avere peculiarly subject to fire damp, no accident of any kind had happened because of the special priK'autions taken to insui'e safetv. ELECTRICITY IN MINING. 149 One installation wliiicii will sei've to exemplif}' tiie lat- est j;oncral features of current transmission, as well as economical y-eneration at the mine, is furnished by the central power plant of 3,000 horsepower installed b}' the coal mining- department of the Delaware, Lacka- wanna and Western Railroad ConiYjanj? in Scranton, Pa., to suppl}^ current for drills, locomotives, hoists, pumps, lights, etc., in the Diamond, Hampton, Brisbin, Hyde Park, and Sloan mines. The alternating current is transmitted at a pressure of 2,300 volts, and reduced at substations at the A'arious mines by step-down trans- formers and rotary converters to direct current, which is employed in the mines, supplemented by two alter- nating induction motors of 800 horsepower each in a water-hoisting sliaft 000 feet from the poAver plant. The greatest distance to which power is transmitted is about lo,00(i feet, to the Diamond mine, which takes about 175 horsepower. The current is furnished to some 1-4 electric locomotives in the various mines, rang- ing from 6i to 13 tons, and to a 120-horsepower electric hoist. Added to the previous plant of the company the generating apparatus represents a capacity of about .5,000 horsepower, supplj'ing current to 1:5 electric loco- motives, 11 motor-driven pumps, 18 operati\'e hoists, 14 motors in a breaker, and 1 electric drill, or a total of 6,820 horsepower in consumption capacity. It lias Ijeen decided to increase the plant so as to transmit current 3 miles, to supply power for operating 25 direct-current niotoi'S at the Delaware, Lackawamia and Western loco- motive repair shops, etc., 100 arc lamps for lighting- freight yards, machine shops, etc., and 1,50(1 incandes- cent lights for a passenger station, freight office, and roundhouse. The most notable thing alxjut this new plant is the fact that the additions to which special ref- erence has been made employ' the latest form of steam equipment in the sliape of steam turbines instead of the more familiar reciprocating steam engine. These tur- bines, two of wliicli were already installed at the time of the compilation of these notes, are each of 50(.t kilo- watts, or about 675 horsepower capacity, and will carry 50 per cent overload for two hours, or 100 per cent overload momentarily, without injurious heating of the generator. Coal cutting machinery. — Electric coal cutters con- stitute one of the largest classes of mining machinery emplojdng electric current. The considerable increase during recent years in the proportion of jnachine min- ing as compared with that of pick mining is doubtless due to the adoption of these machines. According to the report of Mr. E. W. Parker on the production of coal, published by the United States Geological Survey, the number of coal mining machines in use in this coun- try in 1898 was 2,622, but in 1902 it had increased to 5,418; all of these were employed in bit"mi'i used as the return circuit. Tlio ordinary train for this locomotive, which operatcfl with a current of -l.oU volts and from •±(.» to 200 amperes, was 15 cars, each of nhich weighed 1 ton when empty and carried 2.35 tons of coal or 3 tons of rock. 'I'here were two haulage lines, one It, 500 feet long, in a drift, and one 10,-toO feet long, in a tunnel. Another early electric mine locomotive still in use is of 40-hors(>power capacity and uses current at a pres- ELECTKICITY IN MINING. 153 sure of 220 volts, with a M'hecl gauge of (m\y 3(5 inches. This machine is .5 feet 6 inclies in iieight and weighs 10.500 pounds, with 1,800 pounds added to increase traction. Some of the earliest work was done in Ohio, and after fifteen _years of continuous service two of the lirst electric locomotives ever seen in a l)ituminous cfial mine are still in use, hauling the output of a mine oper- ated ])y the Upson Coal Mining Company, of Shawnee. It is interesting to note tiiat this type of locomotive approximated street ear practice, having a single motor with a double-reduction gear. These locomotives, however, are examples of earlier practice in mounting the motors above the truck and gearing downward, thus requiring greater height tlian is now usual. Transition was soon made, however, to types of "terrapin-back" or "turtle-back" locomo- tives, bringing the motor much nearer to the ground, so that it could be coupled with the axles bj^ means of connecting rods. In later types each axle of the loco- motive has been connected with a separate and inde- pendent truck-mounted motor. Modern mining locomotives range in size — according to the work they are designed to perform — anywhere from 2 to 20 tons, and their wheel gauges range from IS inches to the standard railwaj^ gauge of 1 feet 8^ inches. The traction locomotive consists, broadly, of two iron frames within which are contained the motor and driving mechanism, the controller wheel being usually placed in front, vertically, within convenient reach of the motorman, who is seated; in some loco- motives, however, the controller and hand wheel are placed on top of the locomotive, in a horizontal posi- tion. The motors are usually geared to the truck axles by means of cut steel gear wheels, and the trac- tion wheels are shrunk and keyed upon the truck axles, being placed either inside or outside the locomo- tive frame. Electric headlights and mechanical l>rakes are used. The current is taken from an overhead cop- per trolley wire by a grooved brass trolley wheel, mounted on a short, stout trolley pole, and conveyed through the controller to the motors and back to the generators by means of the track rails, Avhich are cop- per bonded, in order to insure a return circuit of thorough conductivity. A speed of from 6 to 10 miles per hour is usually made. Because of the limited dimensions of ordinary mine entries and the light weight of rails, the 20-ton mining locomotive is about the largest that can be used to ad- vantage. Greater hauling capacity issometimesneeded, howev^er, and accordingly a double locomotive has been introduced, consisting of two standard 13-ton mining locomotives, one of which is provided with a 4-motor controller and a 4-raotor commutating switch, so that the complete machine is operated from the one con- troller. Here again, mining practice harmonizes with that obtaining in electric railway work in the adoption of what is known as the " multiple-unit control," by means of Avhich the control of motors over a whole train of vehicles can be brought to one point and there maiu'pulated by one motorman, instead cjf being dis- tributed, with each set under the control of a separate dri\'er. In an interesting paper, read liefore the Western Pennsylvania Central Mining Institute, in December, 11*03, Mr. ^X. L. Affelder, sup(!rintendent of the AIos- grove coal works, in Pennsylvania, stated that a lO-ton 30-incli gauo'e " wondola" locomotive which had been in operation there for more than a year had never been idle a day on account of defect or accident. During tliat time it had hauled nearly 1.50,000 tons of coal, at a cost of less than one-tenth of a cent per ton for repairs. As many as 35 loaded cars, each weighing 3,700 pounds, are hauled l;>y it up a grade of 3 per cent, 250 feet long. At a point in the mine where the grade is ■1.5 per cent in favor of the load for 125 feet, and then 3 per cent for an equal distance, the locomotive holds back as manj' as 35 loaded cars with every car wheel running free. Figures taken from various mines in the coal fields, and compiled by Mr. F. J. Piatt, show a generally high degree of efliciency in electric haulage. At the Green Ridge colliery, Scranton, Pa., the cost of haulage by mule power was estimated at 7.15 cents per ton and the cost of electric haulage at 2.76 cents, showing a saving bj' electric haulage of i.39 cents. At the Sturges shaft of the New York and Scranton Coal Com- pany the cost for haulage by mule power was estimated at 6.58 cents per ton and the cost of electric haulage at 2.62 cents, showing a saving by electric haulage of 3.96 cents. A special feature of electric haulage in mines is the use of '■ gathering'' locomotives. In most coal mines the cars are gathered or collected from the working faces of the rooms 1a' mules or horses, though in some low-veined mines where it is necessary to use very small cars the}' are pushed between the working faces and the "room necks" bj' the miners themselves. Thej' are then collected b}- locomotives and hauled in trains to the tipple or shaft bottom. In many cases it has been difficult to enlarge the entries sufficiently to accom- modate the nuile, because of the cost of "brushing" the roof or "taking up the ))ottom," especially where a hard slate or rough limestone has to be dealt with. One means of obviating this difficulty has been found in the use of compressed air locomotives, but electricity has been found particularly suitable for this class of work. Locomotives used for this purpose are equipped with a reel which carries a flexible insulated cable. One end of this cable is connected to the trolley line, and the current is conveyed to the controller on the locomotive through a contact at the reel. The reel is geared up with the axles or truck of the locomotive, so that the cable can be paid out or coiled up. The gathering loco- motive system can ])e pushed to a considerable distance 154 MINES AND QUARRIES. from the eud of the regular trolley lircuit. An illus- tration of this class of work is to be found in the mines of the Jones and Laughlin Steel Company, at California, Pa. These mines have five 4-ton gathering locomo- tives. A train of emptj' cars is taken from the gather- ing junction and distributed by the motorman into the various rooms in his particular section of the mine, and on the return trip the loaded cars are gathered up. When passing through the entry the locomotive receives its current hy means of a regular trolley pole, but when entering the room neck the pole is fastened down and the insulated flexible cable is hooked onto the end of the trolley wire, the rail still serving as the return cir- cuit. It is stated that a crew of two men on such a locomotive can gather up from 100 to 120 cars, or from 300 to 350 tons of coal, in an eight-hour shift. One well-known mine has equipped its gathering locomo- tives with a separate truck or tender for carrying and operating automatically the cable reel; this, however, is not the preferred practice. In the case above referred to mining locomotives are spoken of as operating with overhead trolley connec- tions. There are instances, however, in which the third-rail method has been applied to such work. This type of rail is used not only for the conve3'ance of the current, but always also as a tooth rail, with which a geared wheel on the locomotive can engage frictionally. According to Mr. Ati'elder, in his paper already referred to, 90 electric locomotives of this sprocket or cog rail type are now in use in coal mines. As a means of climbing grades the electric locomotive possesses ad- vantages which have caused it to be adopted in various parts of the world, subject onh' to questions as to the advisabilitj^ of using the cogged third rail also as a con- ductor for the current. The first of the third and traction rail locomotives of the sprocket type appears to have been installed in this country in 1SU9 in the Star City (Indiana) mine of the Harder and Hafer Company, of Chicago. In metalliferous mines, as distinguished from coal mines, the locomotive is usually smaller. An instance of such work is to be found in the haulage S3^stem of the United Gold Mines Company, of Victor, Colo. — the Cripple Creek district — where one 8 -ton locomotive with a drawbar pull of about 3,500 pounds and a sjjeed of from 8 to 10 miles per hour is used. This locomo- tive is equipped with a single high speed motor, placed in the center and on top of the frame, the motor shaft being connected to the drivers by gears. Current for this locomotive is generated at a waterpower plant lii miles distant by a 3-phase alternating-current dynamo, transmitted at a pressure of 13,000 volts, stepped down and rectified at a substation, and delivered to the trol- ley at 550 volts direct current. It is, therefore, not to be understood that electric loco- motives lind their only employment in coal mines. An interesting illustration of the extensive application of the electric mine locomotive is to be found also in the Quincy copper mine, at Hancock, Mich. The Quincy company has installed 15 electric locomotives, one of which is on the 4:,400-foot level, current being supplied from the surface through substation transformer plants located underground. Another instance which might be quoted is the 8-ton mine locomotive at the Highland Boy Gold Mining Company's mine, at Murray, Utah, employed for hauling slag cars, and using double over- head trolley, so as to dispense entirely with the track as a return circuit. Thus far the subject of mine traction has been con- sidered from the point of locomotives supplied by over- head or underrunning trolleys, or by third rail, with current from a distant source of supply. It is possible, however, to employ self-propelling or automobile loco- motives, equipped with storage batteries, so as to dis- pense entirely with the dangers and inconvenience of tracks and wires charged with exposed live current. The weight of the batterv and the space that it neces- sarily occupies, however, increase the size and weight of the locomotives, and thus place a restriction upon this method of traction in many mining operations. Their use is therefore more particular!}- to be noted in connection with exterior work, and locomotives used for such work have considerable haulage capacity. Several types of this locomotive are in use, either as simple automobile locomotives or as a combination vehicle employing the trolley over sections of the track where such use is permissible and safe. One well-known American manufacturer builds a locomotive of this type in which the batteries are carried upon a separate truck or tender, thus reducing the height of the locomotive to a minimum. This locomotive can be used for ''gather- ing" purposes in low-veined coal mines, ))ut its hauling capacity is necessarily limited, and ))y some authorities it is not considered feasi))le. In another type the bat- teries are mounted on the locomotive and are so ar- ranged that the cells can )je charged while the motors are being driven by current directly from the trolley wire. A smaller size of automobile locomotive is espe- cially adapted to run on curves with a radius of 12 feet and a 2H-inch gauge. The ciu'rent is estimated to cost about 50 cents per day of ten hours for a locomotive weighing from 4 to (3 tons and up to ^1.50 per day for a Ki-ton standard gauge locomotivt'. As a rule, the batteries are not worked quite so hard as those for regular automobile purijoses, the recfuirements per pound of lead, instead of about 7 watts, being not more than 2 or 3. The advantages claimed for tlie batterv, as compared with the trolley system, are that it can be run over any impro\'iscd track of appropriate gauge regardless of wire connections: that the first cost of the battery is usuallj- less than tho outlay on trolley wires and supports, including erection; and that the ex- penses of maintenance with good batteries also average lower.

ELECTRICITY IN MINING. 155 A further modification of traction or haulage meth- ods is found in the movable automatic loader used by the Illinois Steel Compan}". It is difticult to classify this apparatus, but it serves to move ore, and therefore belongs possibl}^ as much in the transportation as in the loading group. The machine consists of an endless chain of metal arms or scoops mounted on a stout metal table or base, which in turn is mounted pivotally on a truck, to enable it to adjust itself to the pitch of the ground and to the height to which the material is to be elevated in loading — as, for example, to a line of the trolley mine cars. The chain of scoops, which is driven by an electric motor, passes around sprockets arranged at the opposite ends of the machine. The motor, which takes current through a cable reel from an adjacent trolley or other circuit, also propels the loader, moving it to any desired point by means of chain sprockets and suit- able clutches. In operation the front edge of the table of the machine is lowered until it rests upon the ground, and it is then thrust forward against the pile of material. As the arms sweep around each arm or scoop gathers up a certain quantity of material and carries it into channels on the table until it reaches the upper end of the machine, when it is emptied into the desired recep- tacle. The arms travel at the rate of about 60 to SO feet per minute, and the capacity of the machine is reported as 90 cubic feet of loose material per minute. This machine is said to have been tested successfully in the handling of limestone, coal, and salt, and to have shown a considerable saving of time and money over hand labor with a shovel. Telpherage. — An interesting and novel application of electric traction methods is to be found in the modern telpherage system. Up to the present time haulage of ores and other raw material in connection with mining work has often been conducted aerially, by means of a traveling wire rope or calile; and this use of the wire rojje represents, in the aggregate, an enormous amount of work. As generally understood, a short stretch of such work, often with a span of several hundred feet between the supports, or between the support and the anchorage, constitutes a "cableway;" in this manner a river or a wide valley is bridged. A ' ' tramway " cable, on the other hand, has frequent supports, and may be several miles in length. Electric telpherage belongs generically in the latter class, as it is not suited to very steep grades. The fundamental difference between electric telpher- age and the traveling rope system is that in the former case all the ropes or cables are stationary, the haulage being effected l)y means of an electric motor or ^'tel- pher-'" traveling along one of the cables, and taking its current, by means of a short trolley pole, from a trolley wire above. In the simpler form the telpher travels along a flexible wire cable; for heavier work a rigid metal rail supported between posts is employed, and upon this loads up to 20,000 pounds in weight can bo moved at a speed of from 800 to 1,.500 feet per minute. This tel])herage method was first experimented with several j'cars ago in England and America, but only within the last 3'ear or two has it been Yjracticall)^ introduced in this countr}^ and abroad. Its present feasibility is due to improvements in motors which can stand exposure, in methods of control, in contact de- vices, in brackets, etc. In an electric telpher sj'stem employed in a limestone quarry in the island of Cuba, the telpher with its cars travels upon cables, except at eight curves, where solid rail is employed. The buckets, loaded with limestone and carried below the telpher, take along the cable a maximum load of 1,200 pounds, with a speed of from 12 to 15 miles per hour. Current is derived from a distant power plant, and to start the telpher all that is necessar}' is to close the switches at the ends of the sj^stem. This telpher travels automat- ically, but in the case of larger apparatus a cab is provided for a telpher man, as on an electric crane, so that he can travel with the load of coal, sulphur, phosphates, etc., and assist in loading and unloading. Even where regular wire rope haulage, in the shape of cablewaj'S, tramway's, and surface lines with rails is employed, it has been found feasible to replace with an electric motor the driving engine operating the drums of cable. A number of plants with electric cable haul- age have been installed in South Africa, Japan, Europe, and other parts of the world, the hauling motor and cable drums being placed usually at the top of the incline, so as to raise the loaded cars. The speed in such work is usuall}' from 4 to 6 feet per second on a grade of from 10 to 1.5 degrees. Hoisting. — Electric hoisting is a growing feature of the use of electricity in mines, and a large amount of work has already been done in this field with the object of replacing the steam engine with the electric motor driven from a central plant. To quote a paper read by Mr. F. 0. Blackwell before the American Institute of Mining Engineers, at Albany, in February, 1903, "The throttling- of steam to control speed, the necessitj' for reversing the engine, the variation in steam pres- sure, the absence of condensing apparatus, the cooling and large clearance of cylinders, and the condensation and leakage of steam in pipes when doing no work are all against the steam hoisting engine. One of the largest hoisting engines in the world was recently tested and found to take 60 pounds of steam per indi- cated horsepower per hour. The electric motor, on the other hand, is ideal for intermittent work. It wastes absolutely no energy when at rest, there being- no leakage or condensation. Its efficiency is high, from one-quarter load to twice full load." As a matter of fact this class of work touches closel_y that above referred to in connection with inclined traction haulage, for after all an elevator is virtually a railway with 100 per cent graile. With these equipments great care is 156 MINES AND QUARRIES. taken to regulate and control the apparatus for safetj' purposes with .safety' and emergency brakes, etc. One of the instances cited by Mr. Blackwell in his paper is that of a flat rope double-reel hoist operating in the Free Silver mine, at Aspen, Colo. In this case the hoist works in a vertical single-compartment shaft, with guides for extra weight, and is driven by a direct- current motor of 120 horsepower at 6.50 revolutions per minute, with difl'erent gears to give 20 and 32 revolutions to the drum. The speed of hoisting ore is from 315 to 6.S0 feet per minute, and that of bailing water from 510 to 1,020 feet per minute. In one gold mine where steampower has been super- seded by an alternating current induction motor, the hoist moves through the shaft at the rate of 1,250 feet per minute, doable deck cages carrying 3,600 pounds of ore, thus elevating 500 tons daih' from a 2,500-foot level. It is stated that this sj'stem has shown a net efficiency of 75 per cent, taking into account all elec- trical and f rictional losses, and that the average cost per horsepower per month has been reduced from not less than $20 to $7. Another illustration of an electric motor mine hoist is furnished by the plant installed in one of the pits of the Gelsenkircbener Bergwerks-Aktiengesellschaft, in Germany. This equipment is designed to raise in one lift, when working at its maximum capacity, a load of 4 tons of coal at a speed of 65 feet per second. The dail}^ hoisting capacity in sixteen efi'ective hoisting- hours would be 2,700 tons with a single unloading platform, 3,200 tons with two platforms, and 4,000 tons with three platforms from a depth of 1,611 feet. The two cages are attached to an endless rope which at the top passes half around and tits into an oak-lined sheath on the circumference of a drum 20 feet in diam- eter. On each side of the winding is a direct current motor, the current supply of which includes a .storage battery. Another interesting hoisting equijiment is that in- stalled in the Fortschrittschacht-Brtix mine, Bohemia, where the hoisting engine is driven by a direct current motor of SO horsepower, with two winding drums, which hoist from a depth of 1^69 feet at a speed of 7s7 feet per minute with a single layer of steel I'ope, the gross load being not quite 4 tons. Still another instance is the hoisting engine driven bj' an alternating current induction motor of 120 horse- power, installed in the Germania colliery, in West- phalia, Germany. The winding drums are each 3 feet 8i inches in diameter, revolving thi'ough double reduc- tion gearing at the rate of 16 revolutions per minute. The motoi', which develops 2<»0 horsepower at the be- ginning of the hoist, winds a normal load of If tons from a depth of 1,50(1 feet at a speed of nearly 10 feet per second; the load can be increased to 3i tons, how- ever, with a corresponding decrease in speed. A large hoist, with winding dnims 19 feet 8 inches in diameter, erected for the Harpener Mining Com- pany, at Dortmund, Germanj^, lifts 100 tons of coal per hour from a depth of 2,300 feet at a speed of 52i feet per second. Another interesting illustration is the plant recently constructed for the famous Comstock mine, at Virginia City, Nev. The power plant is situated on the Truckee river, 32 miles from the mine, and the present substa- tion is located at Virginia City. Electric hoists are used extensively, the largest being of the balanced tail-rope .system, driven by a 200-horsepower variable-speed alter- nating current induction motor. PampuKj. — Electric motors have been found ex- tremel}^ useful and successful in a large number of cases for driving the pumps which are employed to remove the accumulations of water in mines. It is said that the efficiency even of small reciprocating pumps is not far from SO per cent, and that large pumps give as high as 90 per cent. One of the problems encountered in connection with this application of electricity has been the proper reg- ulation of the speed of the motors for the purpose of varying the amount of water pumped. In direct current motors this is done by varying the field strength; the electric pumps which have been in operation forten years past in the Calumet and Hecla copper mines, in Michigan, have adjustments of speed of 2 to 1 under this system. When induction motors are used the windings are thrown into difl'erent combinations for various numbers of poles and rates of speed, and sev- eral frequencies, also, are pi'ovided for. Some alter- nating current motors employed in electric pumping operations are of noteworthy size, developing as much as 650 to 75t) horsepower. For electric pumping the pump itself need embody no special features. Both reciprocating and rotary pumps are used; they may be either horizontal or ver- tical, and reciprocating pumps may be of either piston or plunger type, according to the circumstances of the installation. Where a reciprocating engine is employed, however, it is generally considered advisable to use a double acting pump, either duplex or triplex. A triplex double acting pump does not require so large a motoi- as does a simplex acting pump doing the same duty. To raise a great quantity of water against a certain head takes just so much power, liut if the work be divided among two or three acting cylinders there will neces- sarily 1>e a more uniform flow of water, and hence the strain on the motor and the pump will be reduced. No fewer than 50 electrically dri\'en pumps of the reciprocating class are in operation in the mines around Johannesburg, South Africa, some of them delivering as nmcli as 200 gallons per minute working against a 500-foot head. A striking illustration of electric pumping work is furnished by the Arniston colliery, near p]dinburgh, Scotland. One set of pumps of the 3-throw type, with 11-inch rams and 18-inch stroke, PLATE IX. — MINE PUMP, DRIVEN BY A 1 50-HORSEPOWER MOTOR. ^y^ X. 'FOUR-STAGE MINE PUMP, DRIVEN BY A 1 50-HORSEPOWER MOTOR. ELECTRICITY IN MINING. 157 delivers 500 gallons per minute against a head of (j7.S feet. Each of those pumps is driven by an 8(l-horso- powcr motor and runs with a speed of aliout HO revo- lutions per miiuite. Another set of pumps, similar to the above, delivers 500 gallons per minute against a head of 256 feet through 3,175 feet of cast iron pipe. These pumps are of the same diameter and stroke as the others, and are ecjuipped with SO-horsepowcr motors. Three sets of pumps have also been installed to the dip, each set capable of delivering 100 gallons per minute against a head of -±50 feet. These pumps deliver through 1,200 feet of 6-inch pipe, 9-inch stroke, and are equipped with 25-horsepower motors. On the continent of Europe what are known as ex- press pumps have been largel_y installed, the name being- applied generally to anj^ reciprocating pump run at high piston speed, although applied also to a special system of large, high-speed pumps with mechanically closed suction valves. An example of an electrically driven express pump in mining is one in Bohemia, which runs at the comparativeljr high speed of 200 revolutions per minute and is capable of lifting 132 gallons per minute against a head of 1,312 feet. On account of its rotary motion and its high speed, approximating the speed of a motor, the centrifugal pump also is peculiarl}^ suited for electrical operation, the pump and motor being usuallj' direct connected. This pump has been found of special utility in working against low heads and for handling muddy watei'. The use of rotary pumps coupled direct to small mo- tors running at high speed in place of reciprocating ram or plunger pumps has met with appro\al in Eu- rope. These rotary pumps are made with several cham- bers placed in tandem and are of a type between an ordinary centrifugal pump and a form of reverse tur- bine. One built in Germany has 4 chambers and 1 im- pellers and is coupled direct to an alternating current motor of about 85 horsepower, which, when run at 1,335 revolutions per minute, has lifted i-iO gallons of water per minute to a height of 394 feet. By increas- ing the mrmber of impellers to 6, this pump can be made to reach 1,150 feet in one lift. An efficiency of between 70 and 75 per cent is claimed for this type of pump. Another type of electric pump is the sinking pump. The electric sinking pump can be lowered from one location to another in much less time than a steam or compressed air pump, and as it can be completely su))- merged it does not have to be relocated as often as a steam pump. The question of wliat would happen to an electric motor in a mine if pumps and motors get flooded has often come up. From tests made recently at the University of Liege, Belgium, it appears that a suitably designed polyphase alternating current motor will suffer very little damage. A 3-phase mining motor of a type largely used on the continent of Europe was completely submerged in water. It was run for a quarter of an hour; it was then stopped and allowed to remain submerged, under official seal, for twenty-four hours, at the end of which time it was again run for a few minutes. It was next removed from the water, again put under seal, and left to dry for twenty-four hours. The insulation wiis then tested, and the motor was found to be in perfect order. It would t)e hard to imagine a test more severe than this. As bearing upon this question it is interesting to note that among the pumps in use around Johannesburg, South Africa, at the beginning of the Anglo-Boer War, there were twelve of a well-known American make, each of which was operated by a 5()-horsepower induction motor of American construction with three 15-kilowatt transformers. When the mines were shut down, upon the t)reaking out of the war, the water rose so rapidly that it was impossible to remove the pumps, motors, transformers, etc., and consequently they remained under 500 to 1,000 feet of water. Two and a half years later, wiien peace was declared in South Africa, the water in the shaft was pumped out and the electrical apparatus was removed to the surface. Three of the motors were stripped and completely rewound, but to the general surprise of the experts the condition of the insulation indicated that the rewinding might not be absolutely necessary. Accordingl}' the other nine motors were thoroughh' dried in an oven and then soaked in oil. After this treatment they were rigidly tested, proved to be all right, and were at once restored to regular service in the mine. The transformers were treated in the same manner as the motors, with equally gratifying results. An interesting illustration of the flexibility and adaptability of electric motors for pumping purposes is furnished bj- the Gneisenau mine, near Dortnuind, Ger- many, where a verj' large electric mining plant was in- stalled in 1903. In this instance the pump is located more than 1,200 feet below the surface, and the diffi- culties of installing the apparatus were so great, on account of the small cross section of the shaft, that it was necessary to build up the motor in the pumping chamber, the material being transported through the wet shaft and the winding of the coils being performed in situ. An interesting use of the electric pump associated with the telephone in connection with raining is noted by Mr. W. B. Clarke. In one coal mine, where an electric pump is located in a worked out portion of the mine, the circuits are so arranged that the pump is started from the power house, some distance awaj'. Near the pump is placed a telephone transmitter con- nected to a receiver in the power house. To start the motors, or to ascertain whether the punqjs are working properly, the engineer merely listens at the telephone receiver, without leaving his post. Z/jj/if '/>- for- lighting purposes undei'- ground is not to be of flexibh' cord; in other woi'ds, it is not to undergo the mechanical strain of supporting a lamp. It is especially required that in places where there is lialnlity to fire damp, etc., incandescent lamps must be used, inclosed in gas-tight tittings of strong glass without any flexible cord connections, and with the wires protected by a strong exterior metallic sheath- ing, sufficiently grounded. These general conditions are observed in all well- conducted mines, both in this country and in England, and special pains are taken with regard to the tittings, so as to protect the lamps from injury, and also to get as much light as possible from each lamp. Where the incandescent lamps are subject to vibration special types, with anchored tilaments similar to those employed on trolle}' cars, are used. One feature of electric lighting worthy of note, but not of great importance, is the use of portable miners' lamps. A great many efforts have been made in' this direction with electricity, the lamps depending for their supply of current upon either primary or storage bat- teries. In either case, the drawbacks have been the weight, delit'acy, high cost, and uncertaintj' of the apparatus, and the fact that such lamps are not usually of the safety type bv which the presence of choke damp or other dangerous gases is revealed. In connection with these portable electric lamps for miners, small bulbs and tilaments are used, so as to reduce the con- sumption of current to a minimum, thus making the batteries last longer. Very few records of tests as to electric mine lighting are obtainable; in fact, very few such tests appear to have been made. The most important series is that made some six 3'ears ago in behalf of the Westphalian miners in the testing gallerj' of the consolidated col- lieries near Gelsenkirchen, dealing with the dangers that arise from the use of electrical appliances in gaseous mines. The results of the investigation, embodied in a report made public during the present j'ear, may be sununarized as follows: Naked tilaments raised to high incandescence may or may not cause explosions, and may remain intact and burn after explosion; in most cases ignition seems to follow the breakage or burning of the tilament and the accompanying sparking. Lamps with their bulbs at- tached were purposely shattered, the bulbs and tilaments breaking sinuiJtaneously and producing bad sparking, sometimes with and sometimes without an explosion. In other cases the tilaments remained intact when the bulbs were smashed, and here again explosions some- times followed and sometimes did not. Currents of not less than !>.(i amperes, continuous or alternating, did not produce ignition, but often produced sparking; stronger currents generally did give ignition. Electric incandescent lamps are reconnnended, as affording probably the safest underground illumination. The conclusions as to lamps are: Use stout globes with I'ound bulbs, to prevent cracking from the tlripping of ELECTRICITY IN MINING. 159 water on the hot bulbs; and for further protection, inclose thcni in wire cages. Use low-current lamps (maximum of 9.6 amperes) and high voltage — but not above 150 volts, for all excessive voltages are danger- ous. Have short leading-in wires for the lamps, far apart, to guard against their being bent together and thus making a short circuit; for the same reason avoifl lamps with two filaments in series. Tiiis sunnniiig up is against the common portable lamp, which has the further disadvantage of not indicating the presence of fire damp. But little was done in these tests with arc lamps. They appiear not to ignite coal dust, even in an atmos- phere of 4: per cent of marsh gas, and it is noteworth}' that a dust storm did not make the arc tlare up; but in 6 per cent of marsh gas explosions took place, whether the lamp was already burning or was switched in. Arc lamps, both continuous and alternating, must be con- demned for fiery mines, although it should be noted that arc lamps have been used Avith impunity in rubber works, whei'e the air is saturated with benzine vapor. As regai'ds switches for one or more lamps, it was found that current strength, and still more the voltage and self-induction in the current, play an important part; and while in general slow switching in is danger- ous, on account of arcs forming, rapid motion of the switch is to be avoided in the case of circuits with high self-induction, continuous or alternating. In some cases the switch was thrown 30 times before ignition occurred. Carbon points may glow without causing an explosion so long as there is no arc. Spark extinguishers which form a momentary arc are to be condemned. Hot wire resistances seem in themselves harmless, but danger threatens from contact. A set of resistances was placed horizontally, and one hot spiral touching another caused an immediate explosion. Glowing wires did not cauiie explosions, even when the explosive atmosphere was driven through them by means of a fan; and an iron wire buried in coal dust and heated by the current until it arcked strongly did not ignite the dust, either when it was qvuet or when it was stiri-ed into a cloud. Fusing wires protected by a shunt may be considered harmless; but ordinary safety fuses of lead and tin acted poorly. Ventilation.— A considei'able amount of work is done in mines to-day in the way of ventilation by electric motors, the driving of ventilating fans and blowers by electricity having been found to possess many advan- tages. In addition to the large amomit of work done in tunnels, there is considerable work done in galleries in the way of operating the main fans or blowers for the general ventilation of mines. The larger fans of this class are belt-driven, on account of their very low rates of speed, but the smaller ones are also to be found direct connected to the motors. As pointed out by Mr. Daniel Burns, in his treatise on electricity in British mining practice, in most mines where galleries are driven some distance from the main airway it becomes difficult to ventilate properly ]>y the ordinary methods. The ventilation of such places is always an important matter, especially' in coal mines, where a consideralde quantity of gas is likely to be given oil'. It can best be accomplished by placing a small fan at the entrance to the lieading or drift, and by this means forcing in the required amount of air. The fans employed for this purpose are sometimes driven ))y belt from the motor, but in many instances the motor is direct connected. It is found desirable to inclose both the motor and the switches as thoroughly as possi))le, in order to minimize the possibility of ex- plosions which might result from the gaseous conditions under which such ventilating systems may work. The work of ventilation in galleries ma}' be illustrated by the case of a Westphalian mine with a 40-horsepower motor driving a Pelzer fan, and producing 50,000 cuh)ic feet of air per minute with a water gauge of .3 inches. The motor, which is of the alternating type, is located about half a mile from the generator. Another instance is the case of the Gliickauf mine, at Sondershausen, Germanv, where a belted motor of 100 horsepower has been installed to furnish the general ventilation, although the blower is in the immediate vicinity of the steam plant. Still another instance is the 400-borsepower polyphase motor employed in the Germania mine for general ventilation. Place r mining. — A considerable amount of i^lacer mining work has been done by electricity of late, par- ticularly in the Western states. The best way to afford an idea of work of this character is to cite some of the later examples. The Gold Pan Mining Companj-, of Breckenridge, Colo., which has the largest placer mining plant in the state, if not in the United States, depends chieflj' upon electricity for its operation. The current is generated at a plant some 5 miles from the deposits and is carried to a substation at the mine at a line pressure of 10,000 volts, 3-phase alternating. It is used princi^Dallv for the driving of pumps and the illumination of the works. Large bowlders are moved by two electrically driven portable cranes of the boom type, which use alternating current from the line, without transformation, and each of which is equipped with a motor capable of develop- ing 30 horsepower. A large 150-horsepower constant- speed motor is used to drive a centrifugal pump which assists in keeping the pit dry. A large machine shop, in which are made the large wrought steel water mains employed in the placer system, is supplied with power bv a 50-horsepower constant-speed motor. In California the earliest placer mining, represented in a later stage bv hydraulic working, upon which leg- islation imposed severe restrictions, has been largely superseded by dredging, which appears to have de- veloped into a very profitable enterprise where power can be ol)tained cheapl}'. In fact, it is stated that, 160 minp:s and quarries. with cheap electric-power dredj^ing-, land in which the gold averages less than U) cents to the cubic yard pays for treatment. The gold bearing placer soil of California has a depth of from 10 to 50 feet, being a gravel deposit left in the old river channels. After one or two holes have been put down by drills, for test purposes, and an analysis of gold bearing soil made, the dredges are put to work should conditions warrant it. Two tj'pcs of electric dredge are used to secure the gravel for treatment. In one method the gravel is lifted through centrifugal pumps, while in the other — the method more generally used — it is handled by an endless chain of buckets. The method of operation is very interesting. A boat is built in the basin or excavation where the operations are to be carried on, the necessary equipment is put on board, and the hole is then tilled with water to a depth of from 2.5 to -40 feet. Current is brought to the oper- ating motors on the lioat by means of overhead wires and cables, the cable being usually run out from -iOO to 500 feet from the shore. As a general thing, the cur- rent used is high pressure, alternating 2 or 3 phase, and the transformers for receiving it and stepping it down for use, although sometimes put on the boat, are gen- erally placed on the bank, on a pole, or in a small sub- station. The dredge digs its own channel ahead of it, depositing behind it the soil which has been worked over. It may thus be said to carry its own little pool with it as the work shifts from point to point. The gravel is elevated into a grizzly or similar device, where the rocks are washed out of the soil and delivered to the carrier, which deposits them on the dump behind the dredger. The tine soil is next washed throug-h shakers and rilHes, the gold being deposited on saving- tables, to be taken up with quicksilver, while the worked-over soil is deposited at the stern of the boat with the other residue. Some idea of the character of the work may lie formed from the equipment of the chain-l)ucket dredge oper- ated b}' the Butte Gold Dredging Companj'. This dredge, which has a draft of 5 feet and is about '.i(> by 90 feet on the water line, is fitted with two spuds, each 50 feet long; one, of wood, weighing about lo tons, and the other, of steel, weigliing about 17 tons. The swing- permits of a cut aliout '.»0 feet in width. There are 85 buckets to the chain, each bucket having a capacity of 5 cubic feet. The dredge is operated at a normal speed of 22 buckets per minute, and ordinaril}^ -^^111 handle from 50,000 to 75,000 cu'iic 3'ards of raw material per month. The stacker at the stern of the boat is about 90 feet long and 2^ feet wide. The largest dredge yet installed is that of the Ash- burton Mining (jompany, near Folsom, Cal. , with 7i-f oot buckets. Some idea of the electric power equipment may be foriuerl from the fact that the induction mo- tors for this dredge include one of 150 horsepower for the digger or bucket line, one of 20 horsepower for th(^ winch, one of 75 horsepower for the centrifugal pump, one of 20 horsepower for the stacker, and one of 10 horsepower for the deck pump. The Central Gold Dredging Company, of Oroville, Cal., has a typical equipment of motors of somewhat smaller size and greater variety, including one o" ',' horsepower for driving the buckets, one of 15 Horse- power for the winches, one of 40 horsepower for the centrifugal pump which delivers the water for washing the soil under treatment, one of 15 horsepower for driving the stacker or conveying belt which disposes of stones, one of 15 horsepower for the operation of the shaking screens, one of .3 horsepower for the deck and bilge pump, and one of 30 horsepower for operating the sand pump, which is used occasionallj', when the sand accunmlates too quickly at the back of the boat to deliver it out of the rock pile through a long pipe. The cost of operation in the Oroville territory, includ- ing the cost of electric power, maintenance, labor, repairs, and superintendence, but not including any allowance for depreciation or for interest on the invest- ment, is estimated at from 5i to 6 cents per cubic j'ard. The cost of power is estimated at l-J- cents per kilowatt hour metered. This seems low, but is an actual price. Some of the dredges operate 80 per cent of the time, and their electric power capacity and current consump- tion are indicated b}' the fact that the cost of current per month ranges from f 8()0 to $1,200. MlsceJlaneoxis use nf electricity. — In addition to the more important applications of electricity to mining, alreadj' described, numerous applications of a miscella- neous character might be mentioned. The flexibility of electric circuits and the general adaptability of elec- tric power have led to a wide range of applications, some of which are still in the experimental stage, while many others have already proved successful. An instance ma}^ be found in the sulistitution of elec- tric motors for steampower for driving air compressors, where the latter are still used for the operation of small tools, coal cutters, drills, etc. By this means the com- pressor can lie placed conveniently near the point of application of the air, so as to avoid long and compli- cated systems of piping, with consequent inefficiency and heavy loss, whether of steam or of air. Electrically driven compressors sometimes have belt connections, but in many instances the motor and compressor are more directly connected. An alternating-current induc- tion motor having a capacity of as much as 200 horse- power has been connected to the air compressor by spur gearing. In one California mine the installation of an electric motor to take the place of steampower for driving a lOO-horsepower air, compressor is reported to have reduced the average cost of operation per month from 11,800 to 1(572. X novel and interesting application of electricity to milling- is furnished in the large sand wheel equipment at the Calumet and liecla mine, driven by a 700-horse- ELEO'lUilCrrV IN MINING. 161 power induction motor. To tlic rim of this wheel, whieh revolves in its pit at a speed of 10 revolutions per iniiiute. are attached about 550 l>uckets for liftino- the sand from the copper ore crushinys. The electi-ic sand wheel is considered to etfect a considerahle economy over the previous methods. Sig-nalino- in mines reciuires a great \ariety of appa- ratus, such as telephones, teleg-raphs. hells, and a|ii)li- anees for sending signals according to the indications upon a dial. Of late years the telephone has gained ground rapidly over other methods of signaling. Se\- eral telephone manufacturers in the United States make types of telephones intended for mining work, with special regard to conditions of exposure, damp, etc. The British committee referred to previously records the fact that all of the witnesses before it, except one, spoke in favor of electric signiding in the shaft. Although admitting the fact tint the dilKculties in mines are greater than those in buildings, on account of the juxtaiJositif)n of hea\'y power cables and the pi-esence of nioistui'e. tile <'f)nnnittee recommends tliat as a means of I'cady connnunication between the power house and the motor e(|uipments underground — a mat- ter of gr(>at importance — telephones be put in all permanently installed motoi' rooms, so as to enable the men in charge undergi-ound to inform the engineer at once of any breakdown of motors, machinery, etc., and, if lu'cessary, obtain assistance speedily. The com- mittee notes the fact that for many years bare wires had been in use for transmitting signals without caus- ing a single accident, and that, in fact, th(!y had fre- quently prevented accidents. In addition to the apparatus already described, a variety of appliances are employed for counting- wagons, indicating the level of water, and kindz'ed uses. 30:ii'8— 04- -11 MINES AND QUARRIES BY STATES AND TERRITORIES (163) MINES AND (QUARRIES BY STATES AND TERRITORIES.

(JdiiJ. — The coal fields of Alabama form the southern end of the great Appalachian basin, extending from near the northern ))oundary of Pennsylvania to Tusca- loosa, Ala. The Warrior is the principal tield and un- derlies an area estimated at 7,810 square miles, or nearly ten times the comfjined areas of other fields in the state, known as the Cahaba and Coosa fields.' It is made up of beds in Jefferson, Walker, Winston, Tuscaloosa, Fayette, Marion, Blount, Cullman, and Etowah counties, and contains 23 regular seams, v^arying in thickness from a few inches to some 16 feet, the total thickness of all seams reaching in some places as high as 115 feet.^ This is one of the richest coal fields in the world, the quantity of available merchantable coal being esti- 1 Transactions of the A.meriean Institute of Mining Engineers Vol. XIX, page 296. ^ Alabama Geological Survey, Report on the Warrior Coal Basin 1899, page 4. mated at 108,394,000,000 tons— enough at the present rate of consumption to supply the world for over 270 years. The Cahaba field, the area of which has been estimated at 435 square miles, lies in St. Clair, Jeffer- son, Sliell)y, and Bibb counties, and the Coo.sa field, with an area of 415 square miles, embraces portions of Calhoun, St. Clair, and Shelby counties.'' The earliest notice of the use of Alabama coal appears in a letter 'written in 1834.' Itwas then brought down to Mobile from Tuscaloo.sa in flatboats and sold at the same price as the Liverpool coal, from $1 to $1.50,per barrel. In 1849 but three l)eds were worked under- ground, the rest of the coal being taken from the bed of the Warrior liver and other streams during the low stages of the water. Before and during the Civil War the industry progressed slowly. The coal and iron development of the state began al)out 1870, and with the exception of the panic years 1893-94 each year since has shown an increase in the coal production. The coal counties are Bibb, Blount, Cullman, Etowah, Jefferson, Marion, St. Clair, Shelby, Tuscaloosa, Walker, and Winston; but a little more than one-half of the coal is produced in Jefferson county and over 89 per cent in Jefferson, Walker, and Bibb counties. Cannel, lump, free burning, coking, and gas coals are produced. The manufacture of coke consumed 4,237,491 tons in 1902, 2,760,298 tons of which were made into coke at the mines."

It is at tli(> l:)ottom of the Knox dolomite of the Lower Silurian rocks.'' As early as 1888 ore from near An- niston. in Calhoun county, was identified as bauxite and tested in iron furnaces as to its adaptability for furnace linings.* The deposits are all in pockets and are defi- nitely connected with the numerous fault lines of the region. On the expiration of the patents under which the manufacture of aluminum is now held as a monop- oly, the manufacture of this metal should be added to the industries of the state, since the state po.ssesses both the ore and cheap power for electric generation. Numerous waterfalls and rapids are available for power, thoLigh the abundance and cheapness of coal has much retarded their utilization. The state possesses all the materials for the manu- facture of hydraulic cement, both from natural products (limestone and clay), iind from basic slags and lime. Undou1)tedly this is destined to Ije a growing industry. The state now has one Portland cement plant and two slag cement estal)lishments. Although the present gold jdeld is triffing, the extent of the auriferous deposits makes it probable that the gold mines of the state ma^' again become of some importance. The state possesses an abundance of low- grade ores, which, with improved methods of concentra- tion and extraction, may be worked profitably. The dis- covery of gold in Alabama followed soon after the gold discovery in Georgia in 1829. though there were no mint returns from the state until 1840. Gold is found in Cleburne, Clay. Talladega, Coosa, Chilton, Elmore, Tallapoosa, Chambers, and Randolph counties, both in quartz veins and surface gravel.

The chief districts were the Goldville district, Tallapoosa county, and tiie Ai'ha- coochee district, Cleburne county, the latter at one time employing from 1,500 to 1,800 men in tiie placer mines. The total value of the gold and silver product to date, excluding that for 1895, which was not separately reported, is, according to the estimates of the Director of the Mint, $450,28!), of which $3()5,;iO(i was produced prior to ISSO, the greatest product being between ISIO and 1819. Graphite has been mined in L'lel.)urne and Clay cduii- ties and largely used for furnace linings. The graphite mined in 1!;)U2 was from Clay county. The state is rich in marbles, antl a report of theii- pro- duction was mad(i for 1!»()2. A white marble occurs 1 miles west of Talladega and at several other points in the same county, and a black marble is obtained south of Talladega. Variegated inarl)les are widely dis- tributed in the Tennessee valley, and the mountain lime- stone at many points is of great purity. The colors are gray with led veins, red and yellow, butt with fossils, and white crystalline clouded with red and black.' Pyrite occurring in a semicrystalline state has been prospected in Clay county, and the pyrite output for I'.tui! came from this county. 'Stniu's fur liuililintx and Deroratimi, liy George 1'.

The territor}' ha.s extensive mineral depo.sits, and is famous for the number of it.s big copper camps — among them being Bisbee, Jerome, Clifton-Morenci, and Globe — and the deposits are not confined to one locality or district. It is also a large producer of gold and sil- ver, and the agatized forest near the town of HoU>rook is unique. There are evidences of rude mining by prehistoric people at a number of points, and it is more than prob- able that the reduction of copper carbonates was prac- ticed b}^ the aborigines. Lieutenant Gushing discov- ered ancient oven furnaces in the Salt river valley near ancient copper quarries or pocket mines, with slag and charred grease wood in them, and tests of copper smelt- ing which he made therein, produced copper buttons. ' It seems likely that the iron ochers, malachites, and azurites were mined in a crude way for pigments, and prehistoric turcjutjise mines have been found at several points, notably in the Dragoon mountains.' The various canyons are said to afi'ord sections of e\'erv ge(.)l()gical formation known in America and present unsurpassed facilities for the stud\' of the earth's crust to ti great depth. ^ In addition to the mines referred to in Table 1 and which were the source of commercial production in 1902, coal is found in the territory — the Deer Greek or San Garlos field having been known for many 3'ears — ' American Anthropologist, .January, 1904, pages 95 and 96. ^Tlie Copjper Handbook, liy Horace J.

Extensive deposits of onyx on Big Bug creek, Yavapai county, were located in 1890, since which time the beds have been opened at many places there, and also at Cave creek. The colors are vari- ous shades of red, pink, brown, yellow, and green, the latter predominating. These have been worked to a considerable extent but were idle in 1902. Onyx marble in black and white occurs in Kirkland valley and also near Greaterville.* Tungsten was discovered in the Dragoon mountains near Benson, Cochise county, in 189rt, and the domestic production in 189S was chiefly, from this locality. It is of the manganiferous variety known as hiibnerite.'' It also occurs in the Arivaca district, Pima county; in i\Iohave county, 16 miles south of Hackberry; and at the Mammoth mine in Pi nal county . Gypsum deposits are found near Phoenix and at many other points. In the Santa Rita moun- tains, Pima county, extensive deposits of a thickness estiniiited tit over 2()0 feet were discovered by Prof. W. P. Blake in 189(i.

According to Table 2 the value of the products of manufactures, based primarily upon minerals mined or quarried, amounted to $17,727,872, or 83.2 per cent of the total. The total value of the product of mines and quarries in Arizona in 1902 and manufactures in 1900 was $32,512,564, of which amount mines and quai'ries contributed 34.4 per cent and manufactures 65.6 per cent. The average number of wage-earners in Arizona en- gaged in mining, as reported for 1902, was 5,323 and tiie wages paid amounted to $5,059,065. The average num- ber of wage-earners engaged in manufactures as re- ported at the Twelfth ("ensus was 3,266, and the wages paid amounted to $2,369,065. Thus, the two industries together gave employment to an average of 8,589 wage- earners during the year and paid $7,428,130 in wages. Mines and quarries, therefore, gave employment to 62 per cent of the wage-earners and paid 68.1 per cent of the wages, while manufactures furnished employment to 38 per cent of the wage-earners and paid 31.9 per cent of the wages. Cojyper. — Within the present area of the United States the first western smelting was done before the Gadsden Purchase, in New Mexico and Arizona, which were not separated . until 1863. The copper mines in the Santa Rita mountains near Silver City, N. Mex., were actively worked and their ores suKdtcd early in the century, and the first copper smelting done after the cession of New Mexico and Arizona and before the Civil War was at the Hanover mine. The copper bars were hauled to Galveston, Tex. Shortly after- ward copper was mined on the Bill Williams Fork, Arizona, which empties into the Colorado at Aultrej^ Most of it was shipped as ore, but there stood at Aubrey in 1895 an old ruined water-jacketed furnace of most odd design. There is no local tradition as to when it was used, and, therefore, it may represent the first attempt at water-jacketed furnaces, as applied to copper smelting.' The Clifton copper district, now generally known as Clifton-Morenci, was discovered about 1865 and has been the scene of continuous mining since 1872. It is the oldest producing copper mining district in Arizona.'^ The first smelting was done in 1874 at the Longfellow mine, with a small Mexican adol)e furnace, a blast being supplied by a common blacksmith's bellows.' The second copper district to become productive was the Warren district, better known as the Bisbee mining camp, located in the Mule Pass mountains, Cochise county. It was originally discovered by Henry Warren, but it was not until 1x79 that any work of moment was done. The first water-jacket furnace put up in Arizona, of which there is an authentic record, was ei'ected in the autumn of 1880 at the since famous Coj^per Queen mine, which from that time to the present has been a famous producer.* A great impetus has been given to mining in this dis- trict by the success of the Calumet and Arizona Mining Companv in developing ore with deep mining. Al- though nothing of particular value was encountered above a depth of 700 feet, the immense ore bodies opened up l)elow that level have made this property, which became a producer in 1902, one of the future great mines of the w^orld." The deep developments on an extensive scale inaugurated by a number of compa- nies in this camp gives promise of a large increase in the copper product of the territory within the near future. The Globe district in Gila county has been a large producer since 1882. The original discovery was made many years before, but no locations wei'e made, as copper was at that time valueless in that inaccessible territory." The Jerome district has been made famous by the United Verde, which was originally a small gold and silver mine. The mine is opened on a single monstrous lens of sulphide ore, in slate, said to be at least 1,900 feet long, with an extreme width of 600 feet and hav- ing a dip of 72 degrees. The ore, owing to excess of sulphur, frequently catches fire from spontaneous com- 1 The Mineral Industry, ISOS, Vol. IV, page 280.

Owing to the precipitous nature of the ground and tlic location of the snudtcr and town of .leronu' in a narrow gorge, witli tlie smelter s(|iiarely on toj) of the mine, the ore is handled iu a somewhat unique fashion. All oi-e is sent to the 500-foot le\el and thence (rammed out through a l,30(l-foot tunnid to the roast yard, ^^'hen roasted, the ore is tranuiied back through the tunnel into the mine and hoisted through the shafts to the smelter.' Besides these l)ig camps, there are a numlx'rof othei's which woidd be notable^ in any other section t)f the country. The Ajo copper nun(>s in Yuma county were among the first discovered. Gold iiiiil x/Ii; )■. — Ores of gold and siher are widely distributed and the territory has a nund)er of notaiile mines. The bonanza of the Silver King mine of Pinal county, discoA'ered in 1874, is famotis in the annals of the territory.- It is credited with the jiayment of $2,000,0(10 in dividends. The first locations in Tomli- stone, Cochise county, were made in fsTs. and u[) to January 1, 1SS2. or in less than three years, the gold and silver output of the camp aggregated ft, ;!;■)!•, 2(K», of which over $3,00(t,()(H) had bi'eii disburscti in (li\i- dends.^ Following the detdine in the price of sih'i'r, and partly on account of ditliculties experienced in draining the mines at Tondistone, they closed down aii4.

The combined value of the products of mines and quarries in Arkan.sas in l',H}2 and manu- factures in 1900 was $48,0.38,072, of which amount manufactures contributed 94.1 per cent and mines and quarries 5.9 per cent. The average number of wage-earners in Arkansas engaged in manufacturing at the Twelfth Census was 26,501 and the wages paid amounted to $8,686,291. In 1902 the average number of wage-earners reported as engaged in mining was 2,9-44 and the wages paid amounted to $1,945,4:79. The two industries, therefore, gave employment to an average of 29,445 wage-earners during the year and paid $10,631,770 in wages. Manu- factures alone gave emploj'ment to 90 per cent of the wage-earners, who received 81.7 per cent of the wages, while mines and quarries furnished employment to only 10 per cent of the wage-earners, who received 18.3 per cent of the wages.

Mining on a commercial scale can hardly be considered to antedate 1883, and from that time to 1887 the production was almost entirely confined to Johnson and Polk counties.^ Most of the coal mined is of a very superior qualit}^ In 1902 coal production was reported from Sebastian, Johnson, Franklin, Pope, Scott, Logan, and Ouachita counties, over 68 per cent of the product being from Sebastian countj^ alone.

A marked increase is shown for 1902 in the value of lime- stone crushed for roadmaking. Sandstones and qucwUites. — The whole western side of the state is underlaid with a metamorphosed sand- stone, and quarries have been opened in Carroll, Con- way, Crawford, Independence, Johnson, Polk, Pope, Pulaski, Sebastian, Washington, and White counties.' Nearty one-half of the sandstone product was used for railroad ballast. Oilstones and whetstones. — In the Washita mountains west of Little Rock are large masses of novaculite from which the finest whetstones, known in the market as "Arkansas" and "Washita" stones, are made. The principal quarries are on Quarry or Whetstone moun- tain, near Hot Springs, Garland county, though the stone is also quarried in Saline county. The stones were first put on the market about 1840, in which year a quantity of rough stone was shipped to Europe and cut into whetstones. The next j'ear a small quantit}^ was cut up and manufactured into oilstones at St. Louis, and since that time the demand has continued steady.'^ The Arkansas stone is a true novaculite, an average analysis showing it to contain 99. .5 per cent of silica.' Bauxite. — The bauxite beds of Pulaski county were discovered b}' John C. Branner, state geologist, in 1887. At the time the I'ock was identified it was being exten- sivelj" used for roadmaking. In some cases it contains so much iron that the beds have been prospected with a view to using the material as an iron ore. In other cases it contains so much silica and so little water that it is not distinguishable b}' analysis from ordinarj'' kao- lin, and the varieties grade insensibly into each other with no line of demarcation. It has been found in Arkansas only in Tertiary areas and in the vicinity of eruptive sj'enites. The beds vary greath' in thickness, the thickest found being 10 feet.* The production of bauxite since 1899, when it was first reported, is shown in the following table: Table 5. — Annual production of bauxite: 1S99 to 1903.

All other «iv'«Y?r«&.— Asphaltum was reported from Pike county in 1003 by one operator. The only states producing fuller's earth in 1902 were Arkansas and Florida, the Arkansas product coming from Saline county. It was first discovered in the United States at Quincy, Fla. , in 189.3, where the greater part of the output of the United States has since been obtained. The Arkansas granite, whether as paving stone or as building material, is unsurpa.ssed and has been used to a considerable extent within and without the state.^ The Pulaski county quarries, three in number, were the only ones reported as in operation in 1902, with a product valued at $12,11.5. This is a decline from for- mer years, the product in 1900 having been valued at 162,500. Manganese ore was mined in 1860, though the first report of output was made in 1868. The industry in- creased steadilj^ and a decade ago Arkansas was the principal manganese producing state. Its maximum output was in 1892, when the quantity reported was 6,708 tons. Since 1896 the output has declined rapidly. The entire production has come from the Batesville dis- trict. Independence county. There are vast deposits in Polk countj^ and also in Izard count}', but the high phosphorous contents, distance from railroad, and ex- pense of mining l:ave rendered much of it unmarket- able." The annual production of this mineral from 1881 to 1902, inclusive, is shown in the following table: Table 6. — Annual produrlion of manganese ore: 1881 to 1903.

There are also deposits in southern Arkansas and in other parts of the state. The production of crude mineral pigments reported for r.M)2 was from Clay county. Phosphate beds occur — associated with what is known as the Sylamoro sandstone and the Eurekashale — in the vicinity of Hickory valley, in the neighborhood of Cushman, Independence county, and at other points. The production reported for 19(iy was from Independ- ' Products and Resources of Arkansas, JSS5, page 12. ence county. Phosphate beds are also found in connec- tion with the beds of the Ouachita uplift, and are known to occur in some of the Cretaceous beds of the state. The Cretaceous marls of the southwestei'n portion of the state are ver}^ like the Creensand marls of New Jersey, and are in all probability' equall)' suitable for fertilizers.' As pi-ecious stones, the quartz crystals of Hot Springs, 2 exceeded in value that of all other minerals coni})ined, being approx- imately $15,000,000, which was nearly one-fifth of the refined gold product reported for the United States (including Alaska). Petroleum was the mineral product next in value, borax was third, ctipper fourth, and quicksilver fifth. A largo number of minerals are known to exist in the state that were not mined in connnercial quantities in 1902: Asbestos occurs in Tulare, Yolo, Butte. Placer, San Diego, P^ldorado, and Mariposii counties in small quantities. Barvtes has been observed in CalaA'eras, San Bernardino, Plumas, and Inyo counties. Buhi-stones are known to exist in Inyo county. Corundum is found in drift at San Francisco pass, Los Angeles county, and feldspar is obtainable in jNIariposa county. Iron ore exists in Placer, Sierra, Kldorado, Na])ii, Shasta, Ama- dor, Inyo, Alameda, Del Norte, P>utte, Alpine, antl Nevada counties. Marl is found in various loodities; nickel is oljtainable in San Benito, Kern, Monterey, Tuolumne, and Mono counties; and cobalt occurs in Los Angeles county. Tin ore is known to exist in San Bernardino countv, as well as lead, N\hich also occurs 30223—04 12 in small 'deposits in ^lono. Shasta, Amador, and other counties. Zinc is found in Tulare and San Mateo coun- ties.' A deposit of fuller's earth was opened in 1S98 near Bakerstield, in Kern countj'." In addition to the productive mines, quarries, and wells for wdiich statistics are shown in Talile 1, considerable development was done in 1902. The operators engaged in such work exclusi\'ely, reported an expenditure of $2,92.5,7'*0 for salaries and wages, contract work, sup- plies and materi;ds, and miscellaneous expenses.

' Mineral Resources of the California oil is generally dark in color and heavy in speciiic gravity, differing from the Pcnn.sylvania and Ohio product in that its ))a,se is asphaltuni rather than paraffin. This quality makes it \'ery valualde for the mamifacture of varnishes, lubricants, etc. In some instances the oil is a semiviscid bitumen called maltha or brea. This sii))stance, wlien refined as petroleum, reveals a I'onsiderable by-pi'oduct of a.'sphaltum, which has a limited market on the Paciiic coast for paving purposes. Gasoline and a very satisfactory grade of lubricating oil are produced, but the illuminating product does not compare favorabl}' with the eastern production.

In the Calico district, San Bernardino countj', borate of lime is taken from a tissure vein and this is said to be the onl_y place in the world where deep mining- for borax is carried on.' These deposits, discovered in 1882, are very productive, and the working's have been extended to a considerable depth. An interesting feature in connection with borax pro- duction is the phenomenal decrease in the value from 39 cents per pound to aliout 7 cents at the present time. The deposits of California are very extensive, and in some instances only an increased demand and a conse- quently higher price are necessary to make them profit- able workings. Copper ore. — Copper was not mined in California until 18(30,^ although the mineral was discovered in Los Angeles county asearly as 1840. The period from I8f!0 to 1867 was one of considerable activity, and thou- sands of tons of copper ore were shipped to the Atlantic coast and Europe for reduction. Then occurred a depression in copper production in California due to a fall in prices, and for over fifteen years copper remained as one of the minor minerals of the state. In 1895 and 1896, when the rich deposits of Shasta countj^ began to be worked with success, there occurred a general revival of cop^jer mining in the entire state, and from 1897 copper production has been accounted one of the leading industries of California. Copper deposits are said to occur in almost all of the counties of the state, but the principal i-egions of com- mercially important production are as follows:" Shasta count}', the Coast Range, the Sierra Nevada,, and the mineralized deserts of southeastern California. The Shasta county copper mines, in the nortli central part of the state, are the principal source of production, and the copper belt of the western slope of the Sierras, with its 400 miles of almost continuous copper de- posits, occupies second place. The Coast Kangc cop- per deposits have lieen developed only in Del Norte county, but sup(>rficial prospecting displays the exist- ence of the mineral throughout almost tlie entire length of tlie range.

California asplialtic localities arc thus in the vicinity of the ('(last Rano-e and south of San Francisco bay. A valuable and interestino- deposit of the hard variety exists in Goleta, in Santa Barliara county. The asjilialtuni ap- pears ill a ledge washed liy the Pacific ocean, and is exposed for a distance of several hundred yards. It occurs in pockets of from 1,5(.»0 to 3,(lb0 tons, and is almost pure, containino-cnily a small percentage of sand. Asphaltuni is chiefly used as a rust proof coating for submarine and underground iron pipes. The t'oimner- cial production of the mineral began in California in 1888, and flourished for two years, but the industry did not prove a financial success at the outset, and in 1890 no production was reported.' A resumption of activity in is'.U was more successful. Since that time there has been a general increase of production, and in 1903 California ranked first in this industry. Ciiiil. — Coal was discovered in the state during 1852, although no productive mining occurred until after 1860. In 1902 the production amounted to Sl.Osl short tons, principally lignite, wliicli is a decrease of (■> coal producing states, tenth among the 2ri .states producing iron ore, and ninth among the l.s petroleum producing states. Moreover, it produced all of the uranium and vanadium ;ind almost all of the tungsten reported. In addition to the minerals referred to in Table 1, there are found within the state — although these min- erals were not produced in comuKM-cial ipiantities in 1902 — antimony, arsenic, ct)))alt, corundum, flint and feldspar, fluorspar, graphite, infusorial earth, marble, mica, molybdenum, nickel, pyrites, (piicksilver, serpen- tine, soapstone, tellurium, and tin. Although no bismuth production was reported for 1902, the state supplied the entire United KStates output in 1901, amounting to 3ls.ti shoi't tons, valued at iil25,l:SS. Of this, 253.6 tons came from Lake county and 65 tons from Ouray county. The bismuth con- tents varied fiom 4- to 12 per cent, and the ores also carried gold tmd silver \alues.'

The passing of this expedition through Missoui'i and Kansas ciuised others to join the move- ment, and the reports of the discoveries that were car- ried back to "the states" spread like wildHre. The next spring and summer witnessed the great stampede for Pikes Peak and the Rockies. The first gold bearing lode was discovered ^lay •;, 185!). in what is known as the Gregory mining district in Gilpin countj'.' The mining gi'owth of the state is best re\iewed by considering the development of the more important of the gold and silver producing counties. Boulder county is one of the pioneer counties of the state and has been the scene of acti\-c mining since its first settlement. The mining area is divided by some- what indefinite lioundaries into six mining districts, locally known as (irand Island (Caribou-Eldora), Sugar Loaf, Magnolia, Gold Hill, Central (Jamestown), and Ward. The county records show that the lode claim, placer claim, tunntd site, and mill site l(i<-ations tiled for record aggregate nearly 15,0oo. Of these, LInited ' States patents ha\'e Iteen issued foi-iibout l.ooo. Many of the location certiticates tiled are, of course, ndoca- tions of the same property- The ores are \'aried, in- r at coinini; \-alues: the \alue \u Table 1 is the value at the mine. eluding the common forms of iron and copper sulphide, chalcojiyrite, and marcasite, while the complex siher and copjier sulphides are not uncommon. The so-called telluride belt, extending from Magnolia to Ballarat, produces high-grade gold and silver telluride ores and is noted fen' its tine minerals." Chatl'ee county was formerly a part of Lake county, tuid the discovery of gold in the placer mines near Granite in the early days was almost coincident with the discovery of the placers of Clear Creek and Boulder counties, (ireat activity prevailed until 1863, when there was an exodus to other and supposedlv better sec- tions. The mining districts again became active during 1874-7(1. Since 18'.)7 interest in the mines of this county has been gradually increasing, and the year 1903 marks not only more acti\-e operations but also a great increase in the list of new operators. The old placer mines near (iranite have been operated with improved appliances. The leading districts are La Plata, Hope, and Red Mountain, in the northwestern part of the county; Dewey and Granite, in the northeastern; the Park Range region; the country adjacent to Turret, Whitehorn, Manoa, and Calumet; the Cleora district: !uid the C'hidk Creek district. The county records show the tiling of nearly 14,000 locations for placer and lode cliiims and mill sites and tunnel sites, and the issue of nearly 1,000 Cnited States patents.'' lar]« Kn( ii^^o LMO. -Reiiurt of the .stute P.iircaii of Mines, Cnlorudo, 1901-2 pa" 19 to 21. " •Mhi,l., I.UL' t( COLORADO. 185 Clear Croek county embraces the location of tlie tirst remunerative placer mine located in Colorado, discov- ered in lSn9 near the mouth of Chicago creek. Thi' country records show nearly 23,000 lode and placer claims and mill and tunnel sites, and the issue of about 1,3()(.) United States patents. The county contains some of the most famous mining camps in the state — Idaho Springs, Silver Plume, (Georgetown, and P^mpire. The underground development of some of the older mines has become quite extensive, — the Dives-Pelicon, Bis- marck, and 7-30 group near Silver Plume aggregating some 20 miles of underground workings.' The mining history of Eagle county began with the year 1ST9, following the Leadville boom. The ores of the two regions are of a similar character. The county is rugged and contains within its confines the famous Mount of tlie Holy Cross. The mines are generallj' opened up by tunnels or inclines." Gilpin county, although the smallest in area, has al- ways been one of the most important mining sections in the state. Beginning with 1859, mining has been continuous and its production large. Placer mining- has been prosecuted each year since 1859-(;0, and the explorations of its lode mines have been carried even as deep as 2,200 feet. Central City, Black Hawk, Nevada^'ille, Eureka, and Gregory are some of its fa- mous mining districts, the latter embracing Black Hawk and the Bates and Bobtail hills.' Gunnison, one of the western slope counties, was the scene of a "rush"' during 1880, second to none in the history of the state. Mining camps sprang up at nu- merous points, followed 1)y smelting plants and mills.' The first valid mineral locations were made in Hins- dale county in 187-1. The ores of the district are, how- ever, as a whole, of low grade and require concentra- tion prior to shipment. The mineral resources are great and of a character to insure permanency of output. •"' Lake county has been made famous by Leadville. Auriferous sand and gravel was the quest of the first gold seekers, and in 1860 a party of Gilpin county gold hunters crossed the range and discovered rich jjlacers of California gold which produced several millions and were active for many years. It was not until the seventies that it was discovered that the heavy bowlders and dirt which had bothered the gulch miners were argentifer- ous lead carbonates. Leadville was settled in August, 1877, and at once became a heavy producer. The pro- duction of Lake county in 1902 was 47,357 fine ounces of gold, valued at $903,602, and 3,265,597 fine ounces of silver, valued at 11,659,210. The history of Ouray county began practically with the year 1875, and was made famous at an early day 1 Report of the State Bureau of Mines, Colorado, 1901-2, pages 36 and 37. nhid., pages 57 to 61. 3 Ibid., page 72 ff, *Ibid., page 81.

Sneflles district added greatly to the reputa- tion of the county and swelled the gold product of the state. This mine was discovered early in the eighties and was worked for a number of j^ears to a limited extent on a pay streak near the foot wall, the operators being in ignorance of the immense values contained in an ore band near the hanging wall. Pitkin, another of the leading mining counties, was traversed casually by early prospectors who made no discoveries of importance. But after experience gained at Leadville important discoveries were made in 1879 at Aspen, the most famous camp of the count^^ Owing to the inaccessibility to market, production was restricted until the Denver and Rio Grande Railroad reached Aspen in 1887.'' The veins of San Miguel county, which was estab- lished by legislative enactment in 1883, are sinnlar to those of Ouray and San Juan counties. Gold and sil- ver are generally associated with iron pyrite, chalco- pyrite, lead sulphide, and zinc blende. Before the ad- vent of railroad transportation in 1890, ores carrying high \-alues were the only ones mined to any extent. At the present time the main production from this section is derived from ores having a gross value of from $8 to $20 per ton. Mining operations are con- ducted on a large scale, the largest producers l>eing equipped with expensi\'e milling plants.' San Juan county is noted for the lumiber and con- tinuity of its fissure veins. ]\lining practically began in 1870, and was prosecuted with varying success until the railroad i-eached Silverton in 1882. It has since de- veloped into one of the most important mining sections of the state. Nearly one-fifth of the area of the county is held under mineral locations. Summit county was one of the original sulxlivisions out of which has been carved a number of counties. Its mining history begins with 1859. The placer beds on the Blue river and its tributaries are credited with a production of many million dollars' worth of gold. Ten Mile mining district is also in this county. The ore deposits occur both as fissure and as "contact'' veins, the predominating value being silver, though nearly all the lode veins carry a small percentage of gold. The gold product, on the whole, exceeds the sih'er on account of the product of the placer mines.* The Cripple Creek district, located in Teller county, is at present the most productive gold district in the United States, although the discovery- of gold in that district was not made until Febriiary, 1891. The gold product of Teller county in 1902 was 699,1:87 fine ounces, "Report of tlie State Bureau of Mines, Colorado, 1901-2, page lol 'Ibid., riages 18.'-! t.-. 195.

Coal. — The lignite beds of the upper Missouri were noticed by Lewis and Clark, 1S()3— !■; those of tlu> Laramie plains hy Fremont, 1841!; and those of the Raton mountain region by General Emory as early as 1848. Coal was first developed at Boulder in isco,' although the first production from the state was not reported until 1864. The Marshall mines of Boulder county had already been worked for some years, and the coal was bringing from §1::^ to $l."i a ton in Denver." In 1872 production w'as reported from Weld county, and in 1873 from La.s Animas and Fremont counties. Coal is now reported from is t-ounties. the heaviest producers being Las Animas. Huerfano. Boulder, Fremont. Pitkin, and Gunnison counties, in the order named. These counties produced over 9o per cent of the coal reported for l',i()i.'. The state is rich in the \'ariety of its coals, which range fi'om lignite to anthracite. Lignites are nuned in Arapahoe, Boulder, Douglas, El Paso, .letferson, Larimer, and Weld counties; bituminous in (Jarfiidd. (xunnison, Huerfano, Las Animas, La Plata. ]Mesa. and Pitkin counties; semi})itununous in Fremont, (rar- field, Gunnison, and La Plata counties; and anthracite in Gunnison county.'' For statistical purposes the Bureau of the Census and the (reological Survey have classed the entire production of the state as bituminous.

The iron ore.protluction of the state in VM^l amounted to 306, Tm^ long tons, valued at #1,0S4,424, an average of $3.54 a ton. This high average value of Colorado iron ore is due to its silver contents, and to its availability for use as a fluxing medium when mixed with other gold and silver ores in the smelter. In the production of iron ore is included 13,'J7i) tons of manganiferoirs iron ore, \alued at $.52,371, which was used in the manufacture of spiegeleisen at the steel works.

There is, however, a large copper production l:)y the smelters of the state, who purchase argentiferous copper ores and mattes in the open market.

It should be borne in mind that the clav which is manufactured by the producers was not tak°n into account in this inquiry. Clay valued at $07,1:31: was mined and sold as sueh }»y four establish- ments. The total value of Itrick and tile, and pottery, terra cotta, andfire clay products produced in the state in I8i>0 was 11,071,388.

The state ranked fortieth in iniiiino- in l^Myi accord- I in 1849 .supplied 1(1 furnaces in Litchtieid county with ing- to the value of its product. Its principal mineral a fibrous and massive hematite, which furnished forge products were nonmetallic. Connecticut, in early ])ig of tlie hnest ([utility.' The most important silver- years, was a pioneer in mining enterprise, but later its , lead mine in the state was near ^liddletown. It was opened in 1852, although previously operated to some extent probaldy many years prior to the Revolutionary War.'' ^Minerals occurring in Connecticut but not reported in commercial ijuantities during I'.to:^ are numei'ous. Barytes was mined in New Haven county a.s early as 1870, but none hiis since been reported. Bismuth is disseminated in snuill (juantities through the quiirtz of Fairhekl county. Bornite, green carl)onate of copper, \-itreous coppi'r. copper pyrit(\ ;uid nati\e copper occur chiefly in Hartford, Litchtieid, and New Haven counties. Emery ;ind coruiuhim are found near Litch- held," graphite or plumbago is disseminated through rock in the same county, and glass sand occurs on the shores of Lake Qutissapaug. Copper occurs in many forms throughout the state. A number of contact deposits in sandstone at junctures with gneiss were formerly worked, especially at Bristol.' Large depos- its of infusorial earth and tripoli (jccur, but no produc- tion was reported for 19u2. Lidications of galena are abundant^ throughout the sttite, but there are few localities where lead mining has been carried on to any mines, never verj' productive, ha\'e fallen largely into disuse. The first of the early colonists to turn Ids at- tention in the dii-eetion of mining seems to haxe l)een Governor Winthrop, who, from H).5() to IrtHo, engaged at intervals in examining the metallifei'ous indications of the Connecticut \-alley, in the yicinity of Haddain and Middletown. There is no reason to suppose that any actual mining was ever executed by him.' The copper mines of Simsbury were discovered about 17t).5,- ruined a number of successive proprietoi-s, and were finally made into a state prison, long since aban- doned. In 1709 the first mining company orgtmized in the United States w;is chartered to operate thes(> mines. The material for the ''Granby coppers," coined in 1737, and for otlier coins, including the first United States coinage, wits ol)tained from Simsbury.-' The finding of ore in this locality prom])tcd the discovery of the Schuyler mine in New Jersey in 1719. A colmlt mine in Chatham was worked in I7r granites by a fine grain and light gray color.' The most impcu'tant tpiarries in Connecticut arc found lioidering on Long Island sound, although a ])ro(luctildspathic pink gneiss, excellent for heayy construction and bridge y\ork, is quarried. This stone was used in the founda- tion of the Bartholdi Statue of Liljerty in New York harbor. The Stony Creek qiiarries produced large quantities of red granite, which was used chieth' for building purposes. The red or pink color of this stone is most attractiye. At Ansonia and numerous other points tliere are quarries of more or less importance. There is a large quarry at Sachem Head, which, how- eyer, did not report any production during 11)02.' LimesioDes and doJcDiiltes. — The production of lime- stone during 1902 was yalued at $205,371, an increase of 46.3 per cent oyer the production reported for 1901. All the Connecticut limestones are crystalline in tex- ture" and comparatiyely free from admixture of clay or magnesia, and are therefore well adapted for Irarniiig into lime, for which purpose, except a vei-y small amount reported as flux, the production of 1902 was wholly used. That limestones are not used in this state for roadmaking material is accounted for by the abun- dance of the harder and more permanent granitic rocks. Sandstones and quarfsit/s. — Third in importance among the mineral industries of Connecticut is the quarrying of sandstone, the yalue of the product for 1902 being $12y,.579. The quarries are found princi- pally adjacent to the Connecticut riyer, at Portland, Middlesex county. A small production is also reported from Hartford and New Hayen counties. This stone is sold chiefly in the rough and used for building pur- poses. It quarries easily, works well,'' and possesses a very rich color, but sometimes does not weather well in the changeable climate of northern United States. J^eldsjxir. — Connecticut, in 1902, produced in yalue 29.5 per cent of the feldspar reported for the United States. It was quarried in Fairfield, Hartford, Litch- field, and Middlesex comities. It is obtained from peg- matitic dikes* occurring in gneisses and schists and is chiefly orthoclase. In some localities there are large masses of nearly pure spar, hut generally the occur- rence is an intergrowth of quartz and feldspar. The associated minerals are tourmaline, garnet, and beryl. Crystidline qnai'tz. — The crystalline (|uartz quarried during 1902 amounted to 10,100 shoi't tons, and was yalued at ?32,075, or about three-fourths of the yalue 1 United States Geolegical Surve.,-, ^'ineteenth Annual Report, Part IV, continued, 1897-98, pages "l':!2 to Zj-,.

The mines are situated at New Milford, K(jxbury, and Washington in Litc]i(i(dd c(nnity, and at Southbury, New Hayen county. Crystalline (|uartz is used in wood finishing, to prepai'e the surface of the wood foi- polishing, and in the stone cutting trade, '"' especially ))y the marble men, as an abra- siye. It is also crushed and sized for use in the manu- facture of sandpaper or pulyerized for sale as triijoli. Flint. — The flint production of Connecticut during 1902 was reported as H52 short tons of crude, yalued at i!il,775, and 9(J0 short tons of ground, yalued at §9,800, a total yaluation of $11,575, wdiich is somewhat less than was reported in 1901. The (juarries are all located in Fairfield and Litchfield counties. lUl other minerals. — A considerable amount of mar- ble was quarried near East Canaan, Litchfield county, during 1902, and it was all used fen- building purposes. Deposits of serpentine"" and yerd antique marble occur in the yieinity of New Hayen, but no quarrying w^as reported. Iron ore of importance is mined in the extreme north- west corner of the state, near Salisbury, Litchfield county.' The ores are similar to those of Massachu- setts. Statistics of the production, which is small, have been for some years consolidated with the production of other New England states and can not be shown sep- arately for 1902 without disclosing the business of the only operator engaged in the mining. The Salisbury mines, two in number, are among the oldest in the country, and haye been famous for the qualitj' of their ore and the uses to which the iron made from it has been put. One kaolin mine W'as reported in Litchfield county, statistics for which are included under "all other min- erals " to ayoid the disclosure of individual operations. In Litchfield county, in the vicinity of Boxbury, are also located 2 garnet quarries. A large portion of the product is used in tiie manufacture of sandpaper. More than one-fifth of the entire asbestos production of the United States is mined in Litchfield county. During 1902 the asbestos produced in this state was chiefly in the crude form. Crushing the ore and sepa- rating it by sifting are the only processes thus far undertaken at the mine. A small quantity of scheelite, which when refined assays about 79 j>cr ccMit tungstic acid, was mined during 1902, near Longhill, Fairfield county. It occurs in a quartz vein between au amphibole gneiss and a ))ed of t'rystalline limestone.'' ■'United States (ienlngical Survey, " Mineral Kesourees of the United States," 1901, paL'e 800.

While the state was not a producer in 1902 of feldspar, bog iron ore, greensand marl, lime- stone, and " blue rock." these minerals occur at various points and were mined in former years. Among the minerals occurring in the state which, as yet, ha\-e re- ceived little or no tittention by miners are: Asbestos, amber, and serpentine.' Certain manufacturing industries are closely allied to or are based on the mining industry, using as their raw material the product of the mine or quarry.

During the same year there were employed in all branches of manufacture in the state 22,203 wage-earners, who were paid $9,259,(i61 in wages. In 1902 the mines and quarries of the state gave employn:ent to 501 wage-earners, who received $222,622 in wages. Manufactures, therefore, gave em- ployment to 97.8 pel' cent of the wage-earners and paid 97.7 per cent of the wages; mining employed 2.2 per cent of the wage-earners and paid 2.3 per cent of the wages.

The clay \)roduct of chief impor- tance, however, and that in thi^ production of which the state holds a conspicuous place, is kaolin. The beginning of the industry of kaolin mining in Dela- ware is approximately coincident with that of the same industry iu.st over the line in I'ennsvlvania, where it 'TlieNcw International F.ncycldpeilia, Vol. V, page "tiK,. began in lS3!>.'^ For many years the kaolin deposits of these two stat(n mined at many difl'erent places, the present center of the industry of kaolin or china clay mining is in the vicinity of Ilockessin, in New- castle county. The industry of mining is supplemented in Delawaiv l>y the conversion of the raw kaolin into china clay, and the bulk of the state's product of this mineral is shipped in this form. ^The Mineral Industry, ls98, Vol. VII, page 153 ff. 301'1'H— 1)4- -13 FLORIDA.

The .state ranked thirty-fifth in l'.»ii2 in the vahie of products of mine.s and quarries, with a total of $2,943,806. The mining- industry in the state is con- fined to nonmetallic minerals. Chief among these, Ijoth in extent and development, is phosphate rock. Also, in a relative sense, the state's product of fuller's earth is of importance and its wealth in clay deposits i.s worth v of note. Other minerals found in the state ))ut not commer- cially produced in 1!)02 are: Gypsum, a rather exten- sive bed of which has recently been discovered pear Panasoffkee;' lignite or brown coal, deposits of which occur on the Suwanee river, and at one time were worked for fuel;'' and hydraulic; cement rock, of which a large deposit occurs near River Junction, extending for several miles along the left l);ink of the Apalachi- cola river southerly to Aspalaga, and comprising over 2,000 acres, with a thickness of at least 80 feet. Enough has Ijeen exposed to indicate that the deposit contains sufficient raw material to produce over two billion barrels of cement. The raw matei'ial is white, and the manufactured product is as white as the whitest marble.'' Development work in the state in 1902 was confined t(j phosphate rock, clay, and peti'oleuni, cost $2.5,314, and was of interest diiefiy because of tlie borings and testings made in Sumter county for petroleum.

Nodular amorphous phosphatic deposits in the state were found widely distriliuted many years ago. It was not believed at that time, however, that they were of sufficient impoi-tance either in quantity or (|uality to warrant their exploitation. '^ The industry of phosphate mining, which brought the state into world prominence, followed close upon the discovery in 1886,'' on the Peace river, of phosphate rock of apparently high grade. By 1888^ tentative operations were under way on this river and they met with such marked encouragement that many who had hitherto remained skeptically watch- ing developments came into the field and the year 1889 saw two companies dredging the river bottom with modern and expensive equipment." Thus the industry began in the state with the mining of river pel.)ljle. At the close of 1888 Mr. Albert Vogt, living near Dunnellon, a village on the Withlacoochee river in Marion county, found fossil sharks' teeth in a white subsoil. Some of this white subsoil, being su))niitted to a chemist for analysis, was found to contain a large 'The New International Encyclopedia, Vol. VII, page ,509.

This deposit extended in a more or less "pockety" belt over a considerable district. Active explorations were begun and the known area of beds was rapidly enlarged.^ The mining of river pebble grew rapidly from the first, and when, in 1891, the period of speculation and development of the land deposits began to give way to the systematic production of this rock, the industry im- mediately took first rank. By the end of this year 215 companies had been formed to work the deposits, and the number was constantly increasing.* In 1892 the state succeeded in tripling, as compared with the preceding year, its exports of phospliate rock, compelled con.sumers to acknowledge the industrial value of the product, and forced the majority of foreign producers from the field."* In 1894 the state, b_y exceed- ing the production of South Carolina, became the chief producer of phosphate rock in the world, with a prod- uct of 527,633 long tons; it has occupied this position ever since. The hard rock phosphate is white or creamy, and varies in texture and stritcture. It is mined over a belt reaching from the vicinity of Bay City on the south to the vicinity of Albion on the north, and having an average width of about lO miles with an area of about 900 square miles. Land pebble is foiuid in a numlier of localities in the peninsular portion of the state, tho center of produc- tion })eing in Polk county. Between the Peace river and the Gulf its occurrence is general beneath a lai'ge jDart of the surface, and it is also found in varying quantities in many other places. It is essentially a mass of white phosphatic pebbles lying in a matrix of phosphatic clay or sand, usually of the two in combi- nation. The matrix is easily disintegrated bj^ water and the pebbles are washed out by appropriate machin- eiw. The pebbles vary in size from grains to stones 1 inch in diameter, the average size being from one- quarter to one-half inch. River pebble is found in bars in the rivers of southern Florida, the bidk of the production of this class of rock having been taken from the Peace river. Other rivers carrj'ing the pebble are the Alatia. the two ^lanatees, and the Caloosahatchee. It has also l)een found in manjr other streams entering the Gulf and in Black creek, a tributary of the St. Johns. With these peb- bles, tlie remains of vertebrate animals are often found. In color, the river pehl)les are blue or )>lack and in size they vaiy from 1 inch in diameter down to grains, usuall\' finer as distance down the stream is gained."

Fuller's earth includes a number of clay-like sub- stances having strong absorbent ([ualities.' It is found in many shades of color varying from gray to dark green, turning to white on drying; some varieties ai'e kaolinite and others are smectite." For many j'ears it was employed only as a detergent in fulling cloth, but with the increased production of cottonseed oil, it came to be used for clarifving such oil and also for clarify- ing lard oil and peti-oloum." The utility of fuller's earth for this purpose was discovered in the United States." For some 3'cars the supply had been drawn principally from England, but the new demand stimu- lated the search for commercial deposits in this coun- try. In 1893, quite by accident, the first discover}' of this useful earth in the United States occurred near Quincy, Fla. An effort to burn brick from a bed of claj- failed, the material exfoliating instead of forming a coherent mass. An Alsatian cigarmaker called atten- tion to the close resemblance of this peculiar cla}' to the German fuller's earth." Investigation followed and the deposit proved to be fuller's earth of a very high grade. Since its discovery practically the entire out- put in the United States has come from this state. In addition to the deposits in the vicinitv of Quincy, others have been found at Mt. Pleasant, Norway, River Junc- tion, Ballards point, near Tampa, and at other points." In 1897 a peculiar chocolate-brown earth was discovered near Ocala, which is claimed to be superior to all other American and to all English fuller's earths as a filtering and clarifying agent for oils.'"

The state ranked thirty-fourth in 1902 in the value of products of mines and quarries, with a total of $3, 11 7.. 358. The scope of this branch of industry in the state is quite broad, nineteen different minerals contributing to the total. Gold and silver, in the production of which in former years the state was conspicuous, are still im- portant products, though not commensurate with the abundant deposits of these metals. In recent years the state's most important mineral products have been gran- ite and marble; the quality of the deposits of both these minerals is high and their quantity practically unlimited. From the bauxite deposits of the state more than three- fourths of the total output of the United States is drawn. The extensive occurrence of limestone, iron ore, and slate also add materially to the state's mineral wealth and promise much for future industrial activity. In addition to the nineteen minerals produced com- mercially in 1902, the occurrence of many others has been detinitely established. Some of these have been exploited to a limited extent, while with others develop- ment work has not passed beyond the incipient stage and still others remain untouched. Among the more important of the.se is copper ore, which before the Civil War was successfully mined in Fannin and Cherokee counties. Large quantities of high-grade ore have been taken from the mines of these counties and the deposits are undoubtedly of considerable economic im- portance. Copper ore deposits have also been discov- ered in Fulton, Paulding, Lumpkin, Haralson, Lincoln, and other counties in the northern part of tho. state. The most important form of the ore is the copper pyrites.' Extensive deposits of corundum occur in manj" sec- tions of northern Georgia, but chief! 3' in Rabun county on Laurel creek, where the first discovery of this min- eral in the state occurred in 1S71. Between IS811 and 1S93 the deposits of this county, together with a de- posit at Trackrock, in Union county, were extensivelv worked; their product was one of the main factors in the corundum trade of the country for abrasive pur- poses. The low prices prevailing for this mineral during the last few years are chiefly resiDonsible for the mines remaining inactive. Corundum has also been found in Habersham and other counties.' Of the precious stones, amethysts of good quality have been found in Eabun county; rubies and sapphires of small size have been obtained in connection with corun- dum mining, and green beryl, suitable for cutting, has also been found. Some good moonstones have been cut from the feldspar of Upson county.'' Several dia- monds have been found in Hall county, ranging in value up to $200.' Others have been found in Lumpkin, White, and Dawson counties."

The stone is of a dark gi-een color, mottled and streaked with white and hlaek, ad- mits of an excellent polish, and is very highly prized for ornamental purposes.' Other minerals are anti- mony, arsenic, Ijarytes, bismuth, calcite, cyanite, epi- dote, fuller's eaiih, garnet, glauconite, gypsum, lazu- lite, lead, monazite, platinum, rutile, staurolite, tin, tourmaline, and zinc' Development work in the mineral deposits of the state in 1902 was confined to gold, silver, and cop- per, §32,657 being expended. Certain manufacturing- industries are closelv allied to or are based on the mining industr3% using as their raw materials the product of the mine or ciuarry.

In 1902 there were employed in the mines and ({uarries of tlie state 2,820 wage-earners, who received $1,085,017 in wages. Of tiie combined figures f(n- these two branches of industry, therefore, 90. 7 per cent of the wageicarners, receiving 91.9 per cent of the wages, were employed in manufacturing, while 3.3 per cent of the wage-earners, receiving 5.1 per cent of the wages, were employed in mining.

Siliceoi/s crystalline rocks. — Georgia ranked eighth in the production of the rocks of this group in 1902. Granites and gneisses of excellent quality for building and monumental purposes, and in practically inexhaust- ible quantities, occur throughout the middle and north- eastern parts of the state. One of the most interesting, and perhaps the largest, gi-anite mass in the world is Stone mountain, located in Dekalb county, near At- lanta. This remarkable mountain of rock, whose bar- ren summit attains an altitude of several hundred feet above the surrounding country, with a circumference at its Ijase of 7 miles,' has long been the seat of a very important granite industry,* the first operations dating back to 1850.'' The stone obtained from these quarries is a light colored muscovite granite possessing remark- able strength and quite free from all chemical and phys- ical defects. The stone is extensively used as a building material, and is also largely employed in street improve- ment. There is probably no granite in the South more widely known and more generally used than that fur- nished l)y the Stone mountain cjuarries. jMuch of it is shipped beyond the borders of the state.' Anothei' granite, or rather granitoid gneiss, of almost as much economic importance as thi> Stone mountain granite itself, is the lithonia gneiss. This stone, which differs chiefly from the Stone mountain granite in being laminated, occurs in a considerable area in the eastern part of Dekalb county and in the contiguous parts of Rockdale and Gwinnett counties. The quarries on this Ijelt are very extensive and furnish large quantities of •' Statistics of Georgia, jiage 207. '(jeorgia. Historical and Industrial, ]>age lo4. ^Stones for Building and Decoration, by (ieorge P. Merrill, page 56. GEORGIA. 199 stone for street improvement as well as for o'cneral building- purposes. Georg-ia in liH)-2 ranked tirst among the .states in the production of furliing, of which the greater part was drawn from the quarries on this belt. Granites and granitic gnciss(\s similar to these ocv'ur in many other localities in the northern part of the state, but only at a few points have they been quarried toan^- considerable extent.' In addition to the granites and granitoid gneisses mentioned there are other granites of superior cjuality which are admirably adapted to monumental purposes. These occur mainly in Elbert and Oglethorpe counties. They are Hue grained biotite granites \uuisually free from injurious minerals and admit of a very brilliant polish. They are perhaps luisurpassed in the United States for decorative stonework, and it is only a question of time when the Georgia monumental granite industrv will be of very great commercial value to the state.' 2IaMe. — Georgia ranked second among the states in 1902 in the production of marble. The state's promi- nence as a marble producer is remarkable, in view of the brief period over which the history of this industry extends. The commercial exploitation of the enormous marble resources has been entirely the work of the last two decades. The outcroppings of snowy rock in Pick- ens county were known to the Cherokee Indians, who formerly inhabited this region, and by them were worked to a limited extent and cut into bowls and various other forms. A good specimen of this handiwork may still be seen in the form of a large circular marble bowl, now used as a flower pot in a yard near the Piedmont quarries. It is remarkablj' well preserved, and is valued very highly b}^ its pi'esent owner. ' The tirst sj'stematic working of these outcroppings was by Mr. Fritz T. Simmons in 1840, in Longswamp vallej' near the village of Tate. At tirst all the work required in getting out and polishing the marble, which was then used exclusively for tombstones, was done by hand. About two years after Mr. Simmons had begun work he erected a mill with one gang of saws on the east bank of Longswamp creek, near Marble Hill post office. This was the tirst mill put up in the state for sawing marble. This mill was a somewhat primitive affair, but in principle it was identical with the best mills in use at the present day. A small product was turned out in a desultory way by this and similar mills in the vicinity during several years, but the local demand for tombstones was easily satisfied and existing conditions ' Georgia, Historical and Industrial, page 135. '' Geological Survey of Georgia, Bulletin No. 1, page 9. 'Ibid., pages 10 and 11. did not, therefore, encourage a rapid growth of the in- dustry. In ls,54 operators, who ten yeai's before had opened a (juariy 2 miles (>ast of Jasper, renewed the work at that place. They erected a mill with four gangs of saws and continued fairly successful operations until the work was abandoned on account of the (Jivil War. The product of this mill was sold in the sur- roundingcounties through agents, transportation being efl'ected by wagons.'' At the close of the war operations were again resinned and continued for about two years. Then followed a period of nearly twenty j-ears during which the marble industrv, in common with many others, was at a standstill. In May, 1884, a company was organized with a capi- tal of $1, .500,000.* This date marks the beginning of a very important epoch in the historj' of the development of the marble industry on a commercial scale in Pickens county and the state. Prior to this date Georgia mar- ble was practically unknown to the trade as a building or ornamental stone, and had even a verv local use for tombstones, but on account of its exceptional quality and unlimited quantity, and the energy and business- like methods of the operators, it has found its way to all parts of the United States,* and even to foreign countries.'"' In many of the finest buildings in the coun- try it has been used for Iniilding or ornamental pur- poses. Among these maj^ be mentioned the capitols of Georgia, Rhode Island, Mississippi, and Minnesota; the United States Government building at Boston; St. Luke's Hospital, New York; and the Corcoran Art Gallery, Washington." The most valuable marbles of the state are those of the crj'stalline area, confined in the main to Pickens, Cherokee, Gilmer, and Fainiin counties. These mar- bles occur in a nari'ow belt which I'uns parallel to the Atlanta, Knoxville and Northern liailwa}' from near Canton, in Cherokee county, to the Georgia-North Caro- lina state line, a distance of more than 60 miles. The center of the marble industrv of the state is in the vicin- ity of Tate, Pickens county, just north of the southern end of the belt, where the deposit attains a thickness of 200 feet.' The structure of the marble from the difi'er- ent quarries is essentiallv the same, but there is a marked variation in the color. Some of it is white, some bluish graj^ with. dark blue spots, some with dark blue mottlings, useful for monumental work and inte- rior decorations; others of a variety of shades, such as ■* Geological Survej' of Georgia, Bulletin No. 1, page 11. ^ Georgia, Historical and Industrial, page 41. ^Ibid., pages 41 and 1.34.

These marbles belong to the same deposits that traverse East Tennessee, which are extensively quarried in the vicinity of Knox- ville. The stone has a dark chocolate or light gra}' color and a rather fine texture. The light gray variety, which is always quite compact and highly crystalline, is traversed b}^ dark zigzag lines that give to the polished surface a veiy pleasing efi'ect. These marbles, though of great economic value for building purposes, have not as yet been extensively exploited." Iron ores. — The first iron furnace put into operation in the state was that erected in 1840 on Stamp creek, in Bartow county. Within the following twelve or fifteen years four others were put in blast in the same county. The remains of these old furnaces are still to be seen along Stamp creek and the Etowah river! They were small furnaces of the charcoal type and varied in capac- ity from 2 to -4 tons a day. The ore was taken from the banks in the vicinity or was picked up from the adjacent fields.' The industr3', begun on this small scale in Bartow county, rapidly grew in importance and volume until at the opening of the Civil War it had spread to other counties in this immediate section, and with greatly enlarged and improved furnaces the state's output had increased manj- fold. The passing of the war left the furnaces in ruins, and it was not until 1S70 that development of the iron ore deposits of the state was resumed. The Rising Fawn furnace, in Dade county, blowing in for the first time on June Is, 1S75, was the first in the United States to use the Whitewell hot blast stove.* The .industry, however, has never regained its former importance. Three or four modern plants have been manufacturing pig iron in Polk and Floj^d counties from the high-grade deposits in the vicinity for a number of years," but the bulk of the crude ore of the state is shipped to the furnaces of other states." The iron ores of Georgia constitute one of the most valuable of its various mineral products. The deposits, which are quite widely' distributed througliout the north- ern part of the state, consist of the brown ores or limon- ite, magnetite, and hematite or red ores. The brown ores, which furnish the major portion of the pr(\sent output, are mined in Bai'tow, Polk, and Floyd counties. The most abundant deposits of these ores occur in pockets or irregular deposits in the residual clays that have resulted from the weathering of an extensive mag- ' Georgia, Historical and Indnptrial, page 41. • Ibid., jiage l?A.

The average proportion of metallic iron in these ores runs between 4S and 50 per cent. They occur generally throughout the north- western part of the state, and to a limited extent in other sections. The red iron ore is mined in Walker and Chattooga counties." Vast quantities occur in beds which out- crop in sandstone ridges that encircle the Coal Measures or extend parallel with their eastern and western limits. ' The area underlaid by beds of workable thickness is not less than 3.50 square miles, and falls mainly within the counties of Dade, Catoosa, Walker, and Chattooga.

Gold iiiidsilivr. — Eixcepting early and half legendary Spanish working in and near the valley of the Coosa, the first gold mining in the state j^robaldy began in 1829. In that year, or shortly tifter, miners from the placer mines of Burke county, N. C, following the indications, went southward into Georgia, where they discovered gold on Dukes creek, in \vhat is now White county. This discovery was followed in quick succession by others throughout Habersham and Lumpkin counties, and soon Inmdreds of miners were busily engaged on the various streams in this section in search of the yellow mctid. In 1830 Governor Gilmer wrote to John Mc- Ph(>rson Perrian, then Attorney-General of the United States, saying: ''1 am in dotibt as to what ought to be done with the gold diggers. They, with their various attendants, foragers, and suppliers, make up lietween six and ten thousand persons. They occupy the country between the Chestatee and Etowah rivers, near the moun- tains, gold being found in the greatest quantity depos- ited in small streams which fiow into those rivers."'" The center of gold mining activity' then, as now, was in Lumpkin county, in the vicinity of Dahlonega, which in the Cherokee language means "'yellow money," and in the town of Auraria, miles away, so named b}' John C. Calhoun, who owned a mine near bv.'" ' The Commonwealth of Georgia, page 119. "Ibid., page IIM. '■'(ieological Survey of Georgia, Bulletin No. 4A, page 29. '"The Gold Mines, Scenery, and C'liinate of (ieorgia and the Carolinas, by R. ('. Stone, page 20. GEORGIA. 201 This region was then known as the Cherokee country, as it was occupied by the Cherokee tT'ihe of Indians. The increasing strife and ill will between the Indians and the white miners, and among the white ndners themselves who were quarreling and fighting over the Battle Branch and other gold discoveries, caused Gov- ernor (xilmer in June, 1881,' to issue a pi'oclamation prohibiting gold mining in noi'th Georgia. A dt>tach- ment of United States troops was sent to enforce the proclamation. Two miles north of Auraria, or Knuck- lesville, as it was then called, there was still standing in 18TS the old station house in which General Scott and his troops were stationed to preserve the peace and enforce the knv during these turbulent times." Thus the mining industry was temporarily retarded, but the acquisition by the state of the Cherokee country about this time, and the removal of the Indians from it, gave the gold seekers full sway, and a period of great ac- tivity immediately ensued.' In 1831 the first deposit of gold from the placers of the state was made at the United States Mint.' The industry spread rapidlj^ throughout the northern part of the state and the pro- duction of gold had reached such volume in 1838 that a branch of the United States Mint was established at Dahlonega. This mint continued in operation for twenty-three years and coined 1,381,784 pieces of gold, valued at $6,115,569. However, much of the product of the state during this period was sent to the Philadel- phia and other mints, and the total yield exceeded mate- rially the output of the Dahlonega mint.' Mining activit}^ in the state declined markedly on the discovery of gold in California and ceased almost en- tirely soon after the opening of the Civil War. As the placer deposits, that gave a basis for the greater part of the industry in its earlier stages, have been largely worked over, attention has been directed more and more in recent years to vein ndning. According to the re- port of the Director of the United States Mint for the year 1882, "the work of the year in Georgia was emi- nently successful, both in its steady prosecution and increase. New mines were selected with judgment, carefully equipped, and the work for the most part man- aged with prudence and economy." As a result of the great progress of recent years in deep mining, through the introduction of methods for the economic working of refractory ores, the outlook for the industry in, the state is quite promising. ' The value of gold and silver produced by the state since the discovery in 1829, as compiled from the reports of the Director of the United States Mint, is $17,105,253. The gold deposits of the state belong to the Appa- lachian gold fields, an auriferous belt extending from Mreological Survey of Georgia, Bulletin No. -lA, page MO.

In Georgia the belt breaks up into a number of parallels having a northeast-south- west trend. The most inipoi-tant of these are the Dahlonega and the Hall county belts. The Dahlonega belt cntei's the state from North Carolina in the south- western part of Rabun county, wliere \'aluable placer deposits have )>een worked at the Smith and Moore Girls mines. Farther to the southwest, in White county, the belt increases in width and the mines be- come more numerous. As it enters Lumpkin county it again increases in width, I'eaching its greatest develop- ment in the vicinity of Dahlonega. In Dawson county it becomes more or less broken, but upon entering Cher- okee it again becomes regular and continues with but few interruptions to the Alabama line. The entire length of this l)elt is about 150 miles, while its width varies from 1 to 5 miles. The Hall county gold >)elt lies some It) miles east of th(^ Dahlonega belt and parallels it for more than 100 miles, stopping short about 10 miles north of Atlanta. A third belt, which includes the Acworth, Villa Rica, and Bonner mines, traverses Cobb, Paulding, and Car- roll counties. Still another belt includes some very important mines in Lincoln, Columbia, McDufEe, and AVarren coitnties, and there are many isolated localities besides in which gold occurs in paying quantities." Liiiicntiiniis and dolouuten. — Limestone suitable for lime, fluxing, and building materials exists in great abimdance, especiall}' in the northwestern part of the state. The most extensive of these calcareous forma- tions is the Knox dolomite, a magnesian limestone of great thickness. This formation furnishes much of the lime used in the state as well as a large amount of stone for general bidlding purposes. Other calcareoits forma- tions of scarcely less commercial imi^ortance are the Bangor and Chickamauga limestones. The Chicka- mauga stone has been extensively used in the last few years for the foundations of monuments in Chicka- mauga National Park.* Coal, Intiiminous. — The coal helds of Georgia, which form the northern extension of the Warrior coal field of Alabama, and which were among the first in the countrj' south of the Ohio river to be worked, are lo- cated in the northwestern part of the state, falling in the main within the counties of Dade, AA'alker, and Chattooga. For fifty years or more mining has been carried on in these helds, the greater part of the product at present coming from Dade and Walker ('ounties. Tlie coal obtained from all the deposits in the state is an (Excellent qualit}' of liituminous coal, well suited for coking and steam purposes.

Georgia, until 1891 the only producer of bauxite, still con- tributes the greater part of this mineral to the market. xYll other minerals. — Asbestos is rather widely dis- tributed throughout the northern part of the state, although systematic investigation has been made of the deposits, and hence not much is known of their com- mercial value or extent. However, for many years the greater part of the supply of this mineral produced in the United States has come from the deposits of Georgia, the mine supplying the most of this being- located on Sal mountain in White county.^ The industry of mining hydraulic cement rock in the state began in 18-15, in Bartow county, above the West- ern and Atlantic Railroad. The deposits of the state are of excellent quality and are widely distributed over its northwestern part." The most valual.)le and extensive deposits of clay in the state are those of sedimentar}' origin. They occur in a belt several miles in width from Augusta to Colum- bus. Some of these clays have been used extensively in the manufacture of wall paper, while others are used in making porcelain, terra cotta, tiling, sewer pipe, pot- tery, etc. Dr. George K. Ladd, director of the Mis- souri School of Mines, speaking of the cretaceous tire clays of the state, says: '" Some of these kaolins suitable for fire clays are more refractory than any of the noted fire clays of the United States.'' Fire clays also occur in commercial quantities at other points, and residual and alluvial clays, well suited to the manufacture of bricks and the cheaper grades of crockery, abound in every county in the northern part of the state.'' Graphite occurs in large quantities in many counties along the western margin of the crj'staliinc area. It is quite abundant in Bartow county, where it is now mined and used in the crude state as a tiller for commercial fertilizers.* 'Georgia, Historical and Industrial, page 133. ^ Ibid., page 13(). 'Ibid., pages 1.3(1 and 137. 'Ibid., f.aL'e 143. A light, porous, siliceous stone occurring in Murray, Chattooga, and other counties in northwest Georgia has been known locally for many years as tripoli. Though diti'erent from this mineral in origin it has similar uses in the arts.'"^ For many years the mining of manganese ore has been an important industrj" in the state. During sev- eral of the years since 1880 Georgia has been the chief producer of this valuable mineral in the United States, and since that time has contributed more than one-fifth of the total yield of the country." The manganese ores of the state, like the brown iron ores, are confined chiefly to Bartow, Floyd, and Polk counties, the largest and most productive deposit so far located being near Cartersville in Bartow county.' Mica is quite generally distributed throughout the northeastern part of the state, occurring in man}' places in commercial cpiantities.' Ocher deposits of commercial value are of wide occur- rence throughout the northwestern part of the state, generally as.sociated with the brown iron ores. These ocher deposits, which are really only a pulverulent form of brown iron ore, are quite free from impurities and well suited for making linoleum and paint. The out- put of the ocher mines of the state, which is aliout one- fourth of the yield of the country, is shipped in the main to England, where it is used in the manufacture of linoleum.' Pyrite in great abundance is widely distributed throughout the state, but exists in only a few localities in sufficient f|uantitics to be of commercial importan(.'e. Valuable and extensive deposits occur in Lumpkin, Paulding, and Haralson counties, but no development on an extensive scale has yet been done.* Sandstone has been extensively quarried in Catoosa county. This vari(^ty of sandstone has a dark brown color and resembles very closely the brown sandstone of the Connecticut valley. It makes a beautiful ))uild- ing material and appears to be (juite durable. It is also found in great abundance in the mountain ranges of the northwestern part of the state. Other varieties of sandstone of a light color, and well adapted for build- ing purposes, occur in Lookout, Sand, and Pigeon moun- tains." The roofing slates of CJeorgia occur in great quanti- ties in the northwestern part of the state. The center of the slate quarrying industry in the state is at Rock- mart, in Polk county, where the industry has heen car- ried on for a great many years.'' Talc occurs in the northwestern part of the state in (juantities of economic importance and has been mined in a nunilier of places, especially in Fannin county. * Georgia, Historical and Industrial, page 144.

Gold, .silver, and lead mining overshadows all other mine and quarry interests, as the value of these products constituted over 99 per cent of the total mineral products of 1902. The other minerals mined commercially were limestones and dolomites, sandstones, bituminous coal, copper, precious stones, and siliceous crj^stalline rocks. Other minerals found in the state, but not reported as mined or quarried in commercial quantities in 1902, are as follows: Antimony, a part of the small amount mined in this country having been furnished by Idaho in 1901 and previous years; mar))le, which has been cjuarried to a small extent in former years; mica, mined in former years to some extent in the Roberson raining district, near Moscow, Latah county, and opened up at several other localities;' monazite, said to have lieen found in the gold placers of Oro Fino; nickel ores, re- ported as occurring at the St. Joe mine, Blackbird, Lemhi county;' platinum, which occurs in gold placers of the state; ^ and tungsten ores.* Development work was reported by 32.5 operators in the gold and silver industry.

The mining growtli of the state dates from the discovery of the Oro Fino placer mines in ls(30.' Other discoveries soon followed. The mines at Plorence at the head of Meadow creek were disco\-ered in the fall of 1861; at Boise basin, a very rich placer district, in August, 1862; and at Owyhee in 1863. As in all new gold districts the tirst mining was placer, the location of the vein mines coming later. The Poorman. one of the famous vein mines of the state, was located in the summer of 1865. The gold and silver production of the state in 1866 was estimated at $r7,0(tO,00n, but with the exhaustion of the rich placers it fell oil' rajiidly.

Lead. — Idaho leads all states and territories in lead, on account of the large deposits of argentiferous galenas of the Coeur d'Alene district, Avhich lias furnished the major part of the silver and lead product of the state since the tirst working of the Coeur d'Alene mines in 1886. With the exception of the year 1899, when the product of Coeur d'Alene was reduced by strikes, Idaho has been the first in lead production since 1S96. In 1902 the state produced over 30 per cent of the lead product of the country. Liiriextoiits and dolonutes. — None of the quarrv indus- tries are extensivel}^ developed.

The value of the total product of mines, quarries, and wells of Illinois in 1902, and manu- factures in 190((, was $1,297,964,578, of which manufac- tures contributed 97 per cent and mines and (juarries 3 per cent. The Twelfth Census shows that on the average ;->9.5,llO wiige-eaniers were engaged in manufactures in Illinois in 190O, and that $l91,;"ilO,9(i2 was paid in wages. The average number of wage-earners engaged in mining in 1902 was •10,523, and the wages paid amounted to $26,986,397.

C'vaJ. — The bituminous coal deposits in Illinois un- derlie some 35,000 square miles, or aljout 63 per cent of the area of the state. The coal field extends from the northern boundary of Grundy county west to the Mississippi river, near Rock Island, and south aiong the Mississippi to the north line of Henderson county, where it leaves the river and inclines eastward to the southern part of Jackson county. Although the first discovery of coal in the United States was made in Illi- nois by Father Hennepin in 1679, near the present city of Ottawa, there is no probability that any mines were opened in that locality until long after coal mining had begun in the southern part of the state. The first record of coal mining in the state was in 1810, in Jack- son county. In 1832 several boat loads were shipped from this locality to New Orleans, and in 1833, 6,000 tons were mined in St. Clair county and taken to St. Louis.' Since that date there has been a continual in- crease in the coal production. In 1902 coal was mined in 54 counties, 41 of which showed an increase in production oVer 1901 and 7 a de- crease, the remaining 6 counties not being reported in 1901. Sangamon, with an output of 4,172,722 tons, ranked first among the coal producing counties; St. Clair second, with 2,822,248; and Vermilion third, with 1 Illinois Bureau of Labor Statistics, Twenty-iir.st Annual Coal Eei-iort, 1902, page 1. 2,585,291 tons. Other large coal producing counties are Bureau, Grundy, Lasalle, Macoupin, Madison, and Williamson; each have aproduction exceeding 1,000,000 tons. Illinois ranked second among the coal producing states. The 789 coal operators gave employment during 1902 to 36,617 wage-earners, or 90.4 per cent of all wage-earners engaged in mines and mining in the state ' during the year.

The rocks represent most of the epochs of the Silurian, Devonian, and Carboniferous ages. A notable lime- stone is quarried in Will county, in the vicinity of Lemont and Joliet; it is a fine grained, light colored Niagara stone, soft and easily worked, taking readily a smooth surface, but no polish. ' Of the 160 producing quarries, 55 had a production \'alued in excess of $10,000, and only 7 produced stone valued in excess of $100,000. Cook county, with an output valued at $1,418,408, ranked first among the 30 limestone producing counties; Will county second, with a production valued at $486,268; and Kankakee county third, with $256,017. 29 '' Stones f(jr Building and Decoration, hy George P. iMerrill, page 208 MINES AND QUARRIES.

This plant is still success- fully operated. A second factory was built in ls(!i» at Lasalle. and has since been in continuous operation. The manufacture of Portland cement was tirst reported fram Illinois in 1S94, at Oglesby, Lasalle county.^ In 1902 there were 4 Portland cement plants in this state.

The earliest scientific mention of its occur- rence was in 1819, which describes specimens olitained in the vicinity of Shawneetown. It was tirst discovered in Hardin county in 18.39, and in 1842—13 mining was first actually commenced. The deposits of fluorspar and galena of Hardin county occur in the limestones which underlie the Coal Measures of the states border- ing on the Ohio river. ^ Until 1S98 the Hardin county mines near Rosiclare and those in Pope ccjunty sup- plied all the fluorspar produced in the United States,-^ but since 190() Kentucky has led Illinois in the output of ^United States Geological Survey, "Mineral Resources ef tlie United States," 1902, page 792. ^ Transactions of the American Institute of Minini; Engineers, 1893, Vol. XXI, pages 31, 32, and 3.5.

Leiiil and zinc ore. — The lead bearing district in the northwestern corner of the state is entirely comj^rised within the limits of Jo Davies.s and Stephenson coun- ties.* This district forms a part of the upper Missis- sippi lead region, which occupies an area of some 3,000 square miles in Wisconsin, Iowa, and Illinois. Lead is supposed to have been observed at several points along the Mississippi river by Le Sueur in IToo, and the lead region of the upper Mississippi was located on a map published in France in 1752. ^Mining of lead ore in Illinois was probably not in active progress much before 1827, ■' the period of greatest production being from 184(i to 1850.° Galena, in Jo Daviess county, has always been the center of lead mining in Illinois, and up to the com- pletion of the railroads was the natui'al outlet for the lead mined in Wisconsin. Zinc did not come into the market until 186(\' since which time its production has increased until it is now much greater than that of lead. In 1902 the iiroduction of zinc ore in Illinois amounted to 2,778 tons, while that of lead ore was only 792 tons.

Investigations as to the geological conditions and formations of Indian Territory began as early as ISllV and have been continued from time to time during later years. In 1.S53 the geologist of the Pacitic Railroad expedition, Jules ^larcou, made an important recon- naissance of the southern part and gave to the public a better knowledge of the lithologv and structure of coals in this vicinity. Of the total mineral production for 1902 in Indian Territory, 9.S.7 per cent was coal, bituminous, and the remainder was asphaltum and bituminous rock, natural gas, petroleum, and siliceous crystalline rocks. Con- siderable development work, chiefly in coal mining, was carried on during the year, $167,261 being exiH'iided for this purpose. Copper and gold ores" are known to exist in the Wichita mountains, although they were not mined in commercial quantities in 1902. Sandstones and (juartzites extend over a large portion of the terri- tory,' and limestones and dolomites are found north of the Arkansas river. No sandstone or limestone pro- duction was repoi-ted during 1902.

The above table shows a steady increase in annual production, with the exception of the j-ears 1889, 1891, and 1897, from the time of the first commercial mining operations up to 1902. The coal belt is about 65 miles wide whci'e it enters from Kansas near the northeast corner of Indian Ter- ritory. It extends southward through the territory and then eastward in an L-shaped formation into Arkan- sas. The soirthern branches of Coal Measures, reaching into Texas, are somewhat broken by a covering of Cre- taceous deposits. The coal seams vary considerably in thickness in the difi'erent portions of the territory, in some instiinces being too thin for profitable working. The coal deposits worked near Lehigh and Savanna" vaiy from 3 feet 11 inches to 4 feet 2 inches in thickness, while those of the McAlester district vary from ?> feet 6 inches to 1 feet. The product of the Lehigh and Savanna mines is more especially adapted to steaming purposes'* and both these coals are considerablv utilized bv railroads* while the. McAlester product is a high-grade coke and gas coal remarkably free from sulphur and other impurities. The Savanna product somewhat resembles^ that of the McAlester disti'ict, but the Lehigh coal, although of good steaiiiing (lualitics, is not adapted for coking. A-yi/Kiltiiiii iiikI l>itiiniiri(iiiK r<>cl,\ — The region of asphaltum and bituminous rock deposits in Indian Tei'- ritoiy'* is entirely south' of the Canadian river and extends from the (.'a.stern to the western boundary of the territory." The asphaltite of eastern Indian Ter- ritory is generally of a vein forming variety, jet black in color and brilliant in lustre, and of an exceeding brittleness. One or two (juarries were operated during 1895, but the experiment was not a complete success' owing to the hard and irregular formation of the asphaltic lime rock. Further developments have been more successful. In 1898 and 1899* new discoveries of asphaltic limestone and sandstone w^ere made in the district adjacent to Dougherty and Davis, and a considerable production, chietl}^ of mastic, was reported. There were 6 quarries in operation during 1902 reporting a production valued at $11,751; in addition a considerable amount of de- velopment work was done by one company. All (it her minerals. — One natural gas well was re- ported in the Creek nation and a considerable product was also obtained from an idle petroleum -well in the same locality. As there was but one report, the sta- tistics for natural gas production for Indian Territoiy can not be separately shown. There were 13 petroleum wells reported by 2 com- panies near Bartlesville in the Osage nation and a large product was secured in 1902. Development work is being actively carried on in this vicinity. One granite quariy was reported for the Chickasaw nation with a large production in 1902. The product is not shown separately, as to do so would disclose the operations of an individual establishment. The granite quarried in Indian Territorj^ is not sold in the rough, but is dressed for building purposes and monumental work or prepared for curbing or concrete before it is placed on the market. 1 United States Geological Survey, T\ventv-second .Annual Report, 1900-1901, Part III, page .386.

In 1811 coal dug at Fulton, Perry county, was used by Robert Fulton on the steamboat OtleiDin^ and from 1830 to 1S60 coal was shipped in a small way out of the state." Since 1860 the mining of coal has st(>adily increased, and in 1902 Indiana ranked ,'r to avoid disclosing individual operations. The Ilindostan whetstone of Orange county is said to have been first disco\ered in 1810 and the first quarry was opened in 1825.* The value of the finished product from the six ((tiarries ojxu-ated in 1902 was $lt).',»5(). There was a small production of pyrite in Indiana in 1'.HI2, which was a by-product of coal mining. ■'riiited States (ieologiral Survey, "Mineral Resources of the f'uited States," 1902, page 778.

While wells were drilietl in the early sixties near Faola, in Miami county, practically all prospecting ceased until after the Civil War. The years from about 1S71 uv 1872 to 1890 constitute a second distinct period in the development of the oil wells of the state. Dui'ing this period wells were drilled in Miami and Allen counties. It was not, how- ever, until the introduction (jf laiger capital and better methods su))sequent to 1890 that the real development of petroleiun began in the state."

With extensive coal deposits in both the eastern and western parts of the state, Kentuck}^ ranks eighth among the coal producing states. In limestones and sandstones tit for structural, architectural, and sculptural purposes the state takes high rank. It has excellent iron ores, extensive deposits of superior clays, abundant stores of Chester marls, and notable deposits of fluorspar, carrj'- ing lead and zinc. The state also posses.ses large tields of natural gas and petroleum, and much asphalt rock. It has in abundance the raw materials for the manufac- ture of both natural-rock and Portland cement.' In addition to the productive properties shown in Table 1, 58 operators reported acti\-e mines, quarries, and wells, but no production, in litu2. the work being contined to the development of the properties. These operators employed on an average 3?> wage-earners and paid $25,693 in wages during the year. The salaried ofBcials. clerks, etc., received $23,481; the contract work amounted to 11185,733; the miscellaneous expenses to $22,857; and the cost of supplies and materials to $67,020. The value of the products of the manufacturing in- dustries of Kentucky, based primarily upon minerals mined and ([uarried, and also the value of all manufac- tured products of the .state as reported at the census of 1900, is shown in Table 2.

Pi4r(i1fuiii. — The existence of petroleum in Kentuckjr was undouhtedly known to the earliest settlers through the Indians, but the first known historical facts date from ISlS or isl!), when petroleum flowed so freely from a well dug in ^^'ayne county for salt that it was abandoned tV)r brine. In 1829 the famous American well ^^•as bored in Cumberland county near Burksville.* Although operations in the south central oil district of the state have been carried on in a comparatively small way for niany years, it has only been quite re- centlv that the quest for oil has been prosecaited with vigor.* In 1902 the 39'2 productive wells, located in Barren, Bath, Clinton, Knox, Morgan, Rowan, Wayne, and Webster counties, produced 248,950 barrels, valued at $172,837. Wayne and Bath counties are the largest petroleum producing counties in the state. The following figures from the reports of the United States Geological Survey show the annual production of petroleum in Kentucky since the earliest record. The difl'erence between the Census figures and those of the Survey is caused by the fact that the former represent the petroleum produced and the latter the product marketed.

Primitix't^ attempts wer(.' also made at mining the ore deposits in Livingston count}' subse- quent to the Civil War, and in 1878 nearly all mining in this district of western Kentucky had ceased. Up to 187.S lead onl\' had been mined in this section, but the demand for fluorspar served to maintain a small interest in mining in the southern part of this district f(n- a few years longer, when, owing to a slight drop in the value of this mineral and the cost of transportation, these mines became incapable of competing with the more favorably located mines on the other side of the Ohio river in Illinois.'' Since 1898, however, interest in the fluorspai' deposits of the state has been revived, and in 1902 Kentutdvv, with a production of 29,030 short tons of fluorspar from 14 mines in Crittenden, Fayette, and Livingston counties, was the largest producer of this mineral.

The com- pany now has two good wells each producing from 2,00() to 2,500 barrels each per day.

SiiljiJiirr. — There is a very large deposit of this min- eral about 13 miles from Lake Charles in Calcasieu parish.* In 18HS the Louisiana Oil Company, while sinking a well at this point, struck at a depth of 443 feet a very extensive bed of almost pure sulphur, the analysis showing 99.93 per cent. During 1869 and 1870 other borings showed the average thickness of the deposit to be about 100 feet. Numerous attempts have since been made to exploit it. but the depth of the deposit below the surface and the Itedsof water-bearing sands which overlie it render mining operations difE- cult. In 1895 operations were begun with the Frash system, invented by ~SIy. Herman Fi-ash, of Cleveland, Ohio, and by the use of this method a considerable product was taken from the deposit. The principle of the '"air lift" pump was applied in ISIHI. and l)y this means a product of 265 tons a day was secured. The production from the mines in 1895 was about 800 tons; in 1896, 4,2(10 tons; and in 1897. I.ihk) tons.

The value of siliceous crystalline rocks C[uarried during- the 3'ear represents 72.7 per cent of the entire mineral production in the state, and limestone and slate are second and third, respectivel_y, in value of production. A number of minerals occur, for which no production was reported during 1902, although they were previousl}^ mined to a considerable extent. Barytes occurs spar- ingly in Hancock county. Clay has been mined to some extent, and beds of copper in Washington and Hancock counties have been worked with considerable success. Gold alloyed with platinum has been placer mined in Franklin county; it also occurs with metallic bismuth in Hancock county. Infusorial earth and tripoli are found in Plancock county, in pond bottoms near the coast. Iron ores are found in Aroostook, Washington, Piscataquis, Hancock, Knox, Cumberland, and Oxford counties. Graphite and lead occur in many localities throughout the state. Lead is charged with silver to such an extent that it has been said that "systematic mining might pa}'"' in tlie districts where it occur.s. Manganese is found in Knox, Hancock, Piscataquis, York, and Aroostook counties; marl occurs in the northern jDart of the state; and ocher may be obtained in Androscoggin and Cumberland counties. Molyb- denum .sulphide is found in Washington and Hancock counties and pyrite occurs in many localities, but chiefly in Hancock county. Sandstone, silica sand, native sil- ver, talc and soapstone, and zinc blende are other min- erals not mined, though found here and there through the state. ^ 'United States Geologiral Survey, "Mineral Ke.wiiirce.j nf t\\e United States," 1887, jiages 730 ty AA'elsh farmeivs near Brown- ville, and a ([uarry in this vicinity was opened by A.

The coal beds of the state are so situated as to yield a practically unlimited increase in production should the trade of the seaboard markets demand it/ Quarrying, with a product distributed, in the order of importance, among siliceous crystalline rocks, limestones and dolomites, and slate, constitutes also an important branch of the mineral industrj' of the state. The minerals of known occurrence in the state, that -were not commercially produced in 19(.»2, are as follows: Asbestos, chrome, cobalt, copper ore, lead ores, graph- ite. g3^psum, lignite, manganese, marl, niolybdenmu, nickel ores, quartz, serpentine, and zinc ores.

Coal. — Some authorities place the discovery of coal in Maryland in the year 1801 at a point 6 miles north- east of Baltimore, and Benjamin Henfrey as the dis- coverer.' The first well authenticated discovery was made in ISOi, at a point in Allegany count}' near the present site of Frostburg, by a Mr. Riser.' Various openings were made in the deposits from time to time, and they were worked on a small scale, chiefly for local use, for more than a quarter of a centur^y. In 1830 the industr}- reached its second stage of development, when the first eastern shipment of coal was made from the old Neff mine. This first cargo was loaded at C'umber- land and boated down the Potomac to Washington. For a decade or more the output of coal was confined to a very limited market, on account of the expensive and ineffective transportation facilities. The excep- tional quality of Cumberland coal soon began to attract the attention of users at greater distances, and its min- ing, from the first shipment over the Baltimore and Ohio Railroad, in 1842, developed rapidly, and before long became the most important factor in the mineral industry of the state. The total shipments from the Cumberland region in this first year were 1,708 long tons. The annual output grew in the decade ending in 18.52 to .334,178 long tons, and in 1860 it had inci'eased to 788,909 long tons. During the earlier years of the Civil War the industrj' sufi'ered a slight decline, Ijut re- covered in 1863, and at the end of the next decade, in 1872, the output exceeded 2,000,000 tons. The output remained at about this figure dui'ing the next ten years. The general industrial activitj- of the decade from 1.S82 to 1892 was shared by the coal mining industry in the Cumberland region, and the production again increased rapidly, reaching its maximum in 1891, when tht; state's output was 3,831,2.51 short tons.''

This wedge shaped strip, beginning just north of the Penn.sylvania line and extending across Maryland into West Virginia, is known as the "Cumberland field." In some respects it is one of the most important in the United States.' Maryland's share of these economic coal deposits is known by various names, among which are the "Frost- burg basin" and the "Georges Creek basin." It is situ- ated in an elevated trough to the west of the town of Cumberland, between two parallel ridges, known as Davis and Savage mountains, which are less than 4 miles apart. There are five workable coal seams, ranging in thickness from 14 feet in the "Big Vein" down to 3 feet in the vein of the Bayou formation.* The bulk of the state's coal production is mined in Allegany county, though the number and extent of workable seams in Garrett county afiord much promise for future exploita- tion there. The state's coal product comprises two distinct classes or varieties. That known as bituminous contains a high proportion of volatile gases ;uul less than 70 per cent of carljon, and is especially valuable for the manu- facture of coke and gas. This variety is not extensively mined at present. The other class, known as semi- bituminous, has no superior as a steam coal, and consti- tutes the bulk of the output of the mines of the .state. tSil/'cvrms rryHto.IU>ii> r< and quaiiz'iteH. — The quarrj'ing of sand- stones and quartzitesin the state has continued in a more or less s^'stematic way from the building of the old Potomac canal around the Great Falls of the Potomac, in 1771:, when Seneca sandstone was used in the construc- tion of two locks, down to the present time. This red Seneca sandstone has long Vjeen highly regarded alike for its durability, for the ease with which it can be worked, and for its beautiful colors. It entered largely into the construction of the Smithsonian Institution at Wash- ington. Other occurrences of sandstone that have been exploited, and for which there is a greater or less de- mand, are in Harford county in the Catoctin and Blue liidge mountains, and in Allegan\' county. All othi r nu iii'iudn. — Another factor of the mineral wealth of Maryland is found in the clay deposits, which are widely distributed and in man\' cases possess char- acteristics that render them of exceptional economic importance. The first plant constructed in the United States for the manufacture of fire brick was that built in 1841 at Mt. Savage in Allegany county. The main fire clay dei)osits of the state lie near tlie bottom of the Coal Measures, the beds ranging from 8 to 20 feet in thicks ness. Their exploitation has been a characteristic in- dustrv of the state for more than fifty j'ears, and the brick made from them are considered the best in the country. The clay deposits of the state that are most extensively exploited at present are those comprised in the Columbia and Patajjsco formations. The center of their manui'actiH'e into terra cotta work and potter}" is Baltimor(>.''' The kaolin deposits of Cecil count}^, which are a continuation of the Delaware deposits, have been extensively mined for use in the manufacture of white ware foi' many years.' Feldspar occurs at a number of places in the state, but was produced conunercially in 11»02 from only three mines located in Baltimore, Cecil, and Harford counties. The discoxery of gold occurred in Marj'land in 1849, near Sandy Spring, in Montgomery county, and uiost of the mines subsecjuently opened lie along the south- ei'n boundary of this county in the vicinity of the Great Falls of the Potomac. The known occurrences of gold in the state are confined to the Piedmont plateau, and are in quartz veins. Some \'ery rich specimens have '' Maryland (ieolofrical Survey, A'ol. I, patre -IS ff. "IbicL, page 214 ff. ' Maryland Geological Survey, Cecil c-ounty, jiage 211 ff. MARYLAND. 233 been found in this region, but the deposits of tlie metal are not sutticiently even to render its mining protitable. ' Infusorial earth has been produced in greater (|uan- tities in Maryland than in any other state in the country. The deposits occur at the l)ase of the Chesapeake for- mation, and in parts of Calvert and Charles counties attain a thickness of 30 or 40 feet. The beds have been extensively worked in the vicinity of the mouth of Lyon's creek on the Patuxent river and at Pope's creek on the Potomac.'' The industrj' of marble (juarrying in the state dates probably from 1815, when material for use in the AVash- ington JNlonument at Baltimore was taken from the de- posits at Cockej'sville in Baltimore county. This point continues to be the important marble producing center of the state. The '26-foot monoliths in the National Capitol were taken in lS.59-61 from what is now known as the Beaver Dam quarry. Though there are numerous occurrences of marble deposits, those which have been developed suthciently to demonstrate their economic importance are limited to what is known as the Green Spring valley, extending east and west at a dis- tance of from 12 to 20 miles north of Baltimore. In this belt are located the two quarries mentioned. The stone ' Maryland Geological Survey, Vol. I, page 221 ff. 'Ibid., page 222. is a white dolomite of medium texture, sti'ong and dui-a- ble. Small lenses of compact crystalline marble occur in Carroll and Frederick counties. Also at Texas occurs a coarse! V crystalline white limestone, sometimes known as alum marble, which is exten>ively quai-ried, mainly for (|uicklimeand iiux, th(jugli it was used in construct- ing the lower 1.50 feet of the Washington Monument in Washington.' Ores from which mineral paints are made are of quite connnon occurrence in the state and have been worked at many points. In former years large quantities were obtained from the brown ore deposits in Frederick county and also in Carroll and Harford counties. The Patapsco formation in Anne Arundel and Prince George counties carries easil3f worked deposits of a fine and highly ferruginous clay. This belt at present is the principal seat of the industry of mineral pigment pro- duction in the state." Soapstone occurs in several counties, especially Car- roll, Harford, and Montgomery, where it has been mined at various times. The most extensive deposits are in Carroll county, in a northwesterly dirt'ction from Marriottsville.* ' Stones for Building and Decoration, page 21.3 ff. * Maryland Geological Survey, Vol. I, page 227.

The principal mineral industry of Massachusetts is quarrj'ing, and as shown in Table 1, the value of sili- ceous crystalline rocks quarried in 1902 represents 78.9 per cent, or nearly three-fourths of the entire mineral production of the state. Massachusetts granite was the first to be systematically produced in the United States, and the state continues to lead in that production. ' Sand- stone, limestone, and marble are also quarried in con- siderable quantities, and the statistics for these opei'- ations are given separated' in the table. Among the minerals listed in the group of '"all other minerals " are two of great importance. More than half of the emery produced ui the United States is mined by one operator in ^Massachusetts, and a large propor- tion of the sulphur and pyrite production is also con- tributed by this state. Although these are of great importance, the statistics can not be shown separately because to do so would disclose the reports of individ- ual operators. A number of minerals for which no commercial pro- duction was reported in 19(J2 are known to occur in the state. Among these the following may be mentioned: Barytes, which occurs chiefly as gaiigue, with lead and copper, in Hampshire and Franklin counties; a very hard anthracite coal in Bristol, Plymouth, and Norfolk counties, which can notbemined profitably; chulcopyrite found in pyrite \'ein in Franklin county;" fuller's eartli and garnet found in "Worcester count}', and garnet also in Framingham, Middlesex county; native gold found in 'Stont-H for BuildiiiK ami Dccuratini], ]>y (ieorge P.

MASSACHUSETTS. 235 From the foreo-oitio- table it will bo seen that IH per cent of the total niaimfactured product ot tlio state was based primai'ily upon the products of mines and quar- ries. The total product of manufacture's as reported at the census of IIXX) was $1, 035, lit8, 1)89; there were employed 497,448 wage-earners, who received $228,240,442 in wages. The product of mines and quarries in the state during 1902 was valued at $4,671,855, and there were reported as engaged in this production 4,242 wage-earners, to whom was paid the sum of $2,525,405 in wages. Therefore the value of the product of mines and quarries was but four-tenths of 1 per cent of the com- bined product of mineral and manufacturing industries, 99.6 per cent of the total being contributed by manu- factures. There were engaged in mining and quarrjr- ing eight-tenths of 1 per cent of the total numl)er of wage-earners, and these received 1.1 per cent of the total wages. The manufacturing industries employed 99.2 per cent of the total wage-earners, and paid 98.9 per cent of the total wages.

The production of 1902, according to Table 3, increased over that of 1901 in all the industries presented. The production of siliceous crystalline rocks, as well as that of limestones and dolomites, during 1902 was greater than that reported during any year of the thirteen ■j'ears shown in the table. Siliceous crystalline rod's. — The Massachusetts pro- duction of siliceous crystalline rocks during 1902 was valued at $3,451,397, which is greater than the amount reported for any other state in the Union. Thirty-nine per cent of this value, or $1,347,214, was used for dressed .stone for building and monumental work; 27.1 per cent, or $936,413, was for stone sold in the rough, and the remainder was for paving purposes, crushed stone, riprap, etc., in the order named. In a strictly .scientific sense, most of the siliceous crystalline rocks of Massachusetts are not granites, but eranitites or gneisses. The granitites differ from granite proper in the ab- sence of white mica, while gneisses are crystalline rocks which possess a more or less well-marked banding, usually due to the arrangement of the micas in defined planes.' Although granite bowlders were used in construction as early as 1650," it was not until the early part of the nineteenth century that quarrying was pro.secuted to any considerable extent in Massachusetts. In 1810 the Boston court-house, in 1814 the New South church, and in 1818-19 the fir.st stone block in Boston were constructed of stone introduced Ijy canal from Chelms- ford, 30 miles distant. The quarries of Quinc^', in Norfolk count}^ were opened about 1820, and the his- tory of systematic siliceous crj^stalline rock quarrying in New England begins at this time.'' The stone obtained from this locality is coarse grained and very hard and in color generally a dark blue-gray. It is classed as a hornblende pyroxene, and although the brittle pyroxene makes the production of a perfect sur- face somewhat difficult, it is still used extensively for finished as well as for rough work. Its suitability for interior decoi-ation may be seen in the polished stair- ways and pillars of the Philadelphia city buildings. The Quincy stone was first brought into prominence in 1825 through its use in the construction of the famous Bunker Hill Monument at Charlestown, and what is claimed to be one of the first railroads in the United States was built a distance of 3 miles from these granite quarries to the Neponset river in 1826.* Probabl}^ the Gloucester quarries at Baj' View, in Essex county, were the next to be worked, being opened in 1824. The rock obtained is hornblendic with con- siderable black mica or annite, coarse in texture, and greenish or gray in color. It is hard and tough, and being very durable, it is eminently suitable for building and ornamental work. A number of other quariying localities were opened in Essex county, chieflj' at Rock- port in 1830. The stone cjuarried resembles the Glouces- ter type and may be obtained in massive blocks.'^ The stone quarried at Chester, Hampden county, is clear gray or bluish graj' of medium shade; it is homoge- neous and of fine, even grain." At Dedham, Norfolk county, there is produced an epidote granite of fine grain and light jjink, tinged with green, in color, and at Brockton, Milford, and North Easton a liglit pink variety of coarse biotite is quarried. The stone oljtained at Milford, Worcester county, possesses a more or less plainly marked banding, which increases its beauty without any depreciation of its strength or usefulness. At Monson, Hampden county, a characteristic gneiss is quarried and in a number of 1 The Mineral Industry, 1898, Vol. VII, page 6.37. ^ytones for Buildiii.t; and Decoration, pages 1 and 2. ■"One Hundred Years of American Commerce, Vol. 1, page 189.

Quarryinu- operations have proved very successful in Massachusetts, as the largest deposits arc adjacent to navigable water, which renders shipment convenient and comparatively inexpensi\e. Saiidntonesundquartzites. — The sandstone and quartz- ite production of Massachusetts during 1H03 was \iilued at $487,366. More than one-half of the amount quarried was used in roadmaking and the rest, with the excep- tion of a small amount reported as rul)l)le, was sold principall}^ in the rough or dressed condition for l)uild- ing purposes. In the vicinitj' of East Longmeadow, Hampden countj', are found the principal sandstone quarries, and some of the earliest quarrying operations have been reported in this locality. Sandstone of several colors, tine grained and of a massive type, is obtained, and is used chiefly for building purposes." Geologicallj' speaking, this sandstone locality is a northward continuation of the Connecticut brownstone deposit, extending into Massachusetts as far north as Northampton. This stone is of a Triassic variety and is soft and easilj^ worked.^ A number of quarries in and at)out Boston, prin- cipally municipal in ownership, yiehl a so-called pud- ding stone; this is a rough and durable stone suitable for roadmaking, concrete, etc. , but generally too coarse for ornamental work." These conglomerates in Rox- bur^", Suffolk county, came into use about 1S4(), and have been utilized somewhat in building construction and for the rustic masonrv work of tlie Boston system of parkways. Lmtestones and dolnmiten. — Massachusetts limestones and dolomites are obtained entirely in Berkshire county; the production during 190ii was \-ahied at ^.33;*, .349. They occupy a belt along the Housatonic river and are of the same age as those of Rutland valley, Vt., to which stones they bear a close resemblance.* 2Iarhlc. — The production of marble in Massachusetts for 1902 was valued at $165,489 and (juarrying opera- tions were chieflv repastern counties. The rich brown hematite ores of western Mas.sachusetts were developed in 1750 and the first furnace was built at Lenox, in Berkshire county, in 1765." This county was tli(^ only ju'oducer of iron ore in the state during 1902. The only pyrite mines in Massachusetts are located in Franklin county and were (opened in .hme, 18.S2. The mineral is an almost pure iron pyrite and the width and continuity of the ore vein, as well as its great length, depth, and jjurity, make it one of the most remarkable deposits e\er known." Talc is mined in Berkshire county in the vicinity of Dalton. About one-half the product is used by foun- dries and the balance is prepared as talcum powder or- is used as an ingredient of paint.

The minei-al re.sources of Michigan are exteu.-iive and varied. The iron ore dcpo.sits of the Upper Fenin.sula along the shorew of Lake Superior are extensive, and the annual production i.s enormous. The copper mines of the state are among the richest in the woi-ld, and the -celebrated Calumet and Hecla mine is claimed to he the most profitable copper mine known. Although coal underlies some 6,700 square miles of the state's area, it is of inferior quality and not pure enough for smelting purposes. The Huron grindstones have been (juarried for many j'ears, and Michigan ranks second in their pro- duction in the United States, Ohio being tirst. Valuable deposits of gypsum occur, which, in the vicinity of Grand Rapids and Alabaster, are extensively (juarried -and used in the manufacture of stucco. The Lake Supe- rior region also produces gold, silver, agate, sardonyx. chalcedony, cornelian, jasper, and opals, as well as roof- ing .slate, freestone, mar))lc, and limestone.'

" Census figures. Iron ore. — The existence of iron ore deposits on the southern border of Lake Superior was known to white Indian traders as early as 1830. Tiieir commercial value, howe^-er, was not realized until 1844. In 1845 the celebrated Jackson mine in the Marquette district was located and the first forge was built. Th(; hrstiron was made in this region during the following year.' The first iron ore shipped from the Marquette mines for commercial purposes was in 1853, and since that time there has been a steady increase in the output. In 1877 the tirst shipment of ore was made from the Menominee district and in 1884 from the Gogebic dis- trict. The yearly production of the Michigan iron ore iiiines has increased from 948,553 long tons in l.s72 to 11,135,215 tons in 1902. From 1890 to 1900 Michigan ranked first among the iron ore producing states, but since that time it has ranked second, Minnesota l)eing first. By far the greatest quantity of Michigan ii'on ore is of the red hematite variety, although magnetite is produced to some extent. The following table, compiled from the reports of the United States Geological Survey, shows the practically steady inci'ease in the iron ore production in this state from 1854 to the iiresent time: Table J.. — Annual pjroduclion of iron ore: 1S54 to 190S.

Other explorers found copper in that locality in the succeeding century, and in 1770 Capt. Jonathan Carver, of London, published a book, telling of the rich deposits of copper in the Lake Superior region. This led to the formation of a coppei' mining companj^ in London. During the winter of 1771-72, this com- pany sent over from England a party of miners who conducted operations along the Ontonagon river. The attempt failed, however, and nothing further was done at copper mining for seventy years." Throughout the entire copper region numerous ex- cavations have been found. It is believed these were made at a very remote period, for the purpose of secur- ing copper. Some of this mine work is on an extensive scale, attaining, in one instance, a depth of 50 feet in the solid rock.'' The formation carrying the cupriferous lodes and veins of the Lake Superior district is composed of old lava flows, supplemented by beds of conglomerate which have been formed by the deposition of rocks, broken from adjacent shores, upon old sea beds. This belt of rocks, named after the Keweenaw peninsula, where it predominates, is of considcralile extent. It forms a trough or synclinal, the southern edge of which out- crops on the Keweenaw peninsula, and to the westward along the southern shore of the lake.* The discoveries of Dr. Douglas Houghton led to the exploitation of the Lake Superior district, now among the most, valuable and productive copper fields in the world. The first copper in any considerabh', quantit}' was taken from what was later known as the Clifl" mine, in Keweenaw county, in 1846. About 1847 the Minne- sota mine, in Ontonagon county, was opened. The mine was closed in 1870, after having paid dividends of Kl9, Tlif OopptT liandb(jnk, liy Ilorare .T. Stevens, \'(>1. Ill, [Jiige '.Metallic Wealth of the t'liited States, l.y .1. 1).

The mine has recently been reopened. Tlie famous Calumet and Heela mine, producing about 8 per cent of the copper output of the world, was opened in 18(!<3. Up to 1903 this mine had contributed about 55 per cent of the total copper production of l^licliiy-an.' The now practically' abandoned mines on Isle Koyal were probably worked long before the arrival of the white man, but the earliest historic explorations were contemporary with those in Keweenaw and Ontonagon counties. Several mines were located and worked to some extent until 1883. At the present time new ex- plorations are being made in this region.'' The output of copper from ore mined in Houghton, Keweenaw, and Ontonagon counties was 76,385 long- tons in 1902, or 26. S per cent of the total production for the United States. From 184:7 to 1887 Michigan ranked first among the copper producing states, hut since that time, with the single exception of 1891. ]\Ioii- tana has ranked first and Michigan second. In 1901 Michigan contributed 13.1 per cent of the world's pro- duction of copper. The following table compiled fi'om the reports of the United States Geological Survej', shows the annual production of copper in the United States and in Michigan from 1815 to 1902, and the percentage of Michigan's output to that of the United States: Table 5. — Annual production of copper in the United Statex and i)i Michigan, with per cent of total: 1845 to 1903.

In 1878 coal was mined in the Owosso district in Shiawassee county, and this field has been worked continuously since that year. Successful opera- tions first began in the Saginaw disti'ict and in Bay county in 1895.

The stone is of medium fineness of texture and of a light brownish red color, often curiously spotted or mottled with gray, and is known locally as '"raindrop .stone." ^ The total value of the stone produced Ijy the 9 quarries which operated in 1902 was $188,073, while in 1901 it was $290,578. The principal quarries are located in Baraga, Houghton, Keweenaw, Ottawa, and Marquette counties. The largest grindstone quarries in the state were opened in 183.S at Grindstone city, Huron county. The Huron grindstone is a very fine grit, soft and wet when fresh, but growing hard and dry upon exposure.^ In the prouuction of grindstones ^lichigan is second among the states, Ohio standing first. The graphite mines are located in Baraga county, the 13 petroleum wells in St. Clair county, and a small (juantity of day is jiroduced in Ontonagon county. ^Stone.s for Building and Decoration,^ by Geoi-ge P.

Natural-rock cement has been manufactured near Mankato for many 3"ears. and the famous red pipestone is found in Pipe- stone county. In addition to the minerals enumerated in Table 1 the following, which are known to occur in Minnesota, were not produced in commercial quantities during 1902: Feldspar, jasper, molybdenum, reported as occurring in quantities near Portage, Aitkin county, and slate. In 19(.)2 there were 15 operators, exclusive of those referred to in Table 1, who reported active mines but no production, the work being confined to the care and development of the properties. These operators em- ployed an average of 117 wage-earners and paid $73,700 in Avages during the year. The miscellaneous expenses amounted to $2,346 and the cost of supplies and materials to $66,310.

From the figures in Table 2 it will be seen that the total value of the products of manufactures in 1900, based primarily upon minerals mined or quarried, amounted to $2,8,143,297, or 10.8 per cent of the total of all manu- factures. The total value of the output of the mines and quarries of Minnesota in 1902 was $25,729,545, or S.9 per cent of the total value of the products of all mining and manufacturing industries in the state. According to the census of 1900 the average number of wage-earners engaged in the manufacturing indus- tries was 77,234, and the total wages paid amounted to $35,484,825. The average number engaged in mining and quarrying in Minnesota in 1902 was 9,760, and the total wages paid amounted to $6,391,184. The manu- facturing and mining industries combined, therefore, gave employment to 86,994 wage-earners and paid $41,876,009 in wages. Of these totals, manufactures employed 88.8 per cent of the wage-earners and paid 84.7 per cent of the wages. Mines and c^uarries gave emplojrment to 11.2 per cent of the wage-earners and paid 15.3 per cent of the wages.

(241) 242 MINKS AND cniAHRIES. Iron ore. — The Minnesota iron mines thus far devel- oped are in the Mesahi and \'ermilion rano(>s in St. Louis county, and lie about lot) miles north of Duluth. They are about 20 iniU's apart and extend in an easterly and westerly direction, with the ore deposits scattered along the ranges in groups at irregular inter\als; and thus, besides being very narrow, as compared with their length, the ore lielts are composed of nonproductive reaches for miles, with occasional groups of rich mines. The ore. confined to red hematite variety, is soft, some- times yielding (i7 per cent of iron, and so low in ])lios- phorus as to come within the Bessemer limit. The occurrence of iron ore of the azotic system in northern Minnesota was first mentioned in ISoO. hut no particular importance was ascribed to this ore.' II. H. Eames, state geologist of Minnesota in 18B5 and isCiG. was the first to observe and report iron ore on both the Vermilion and Mesabi ranges and to consider it of any value.' The first iron ore was shipped from the Vermilion range in 1884 and from the Mesabi range in ls',>2. The total production for 1884 amounted to United States Geological Survey: Table 4. — .[iiiiiiul jtr(/iliuiil.

At present the only ones quarried are located in the counties of Blue Earth, Brown, Dakota, Dodge, (xood- hue, Hennepin, Hou.ston, Lesueur, Nicollet, Olmsted, Ramsey, Rice, Washington, and Winona. During 1902, 77 quarries were operated, the value of their product being $905,857, while in 1901 the value of the product from the operating quarries was $522,778. Kasota stone, or pink limestone, which is found in the quarries at Kasota luid Mendota, Lesueur county, is nun-h admired and highly valued. Other limestones quarried are usually bufi', light blue, or drab in color. The two cement producing operators, data concern ing whose plants tire included with limestones and dolomites, manufactui-ed nothing but natural rock cement. Sandstones anil (/iiartsltes. — The 13 (juarries operat- ing in 1902, in the counties of Carlton, Lac qui Parle, and Pine, produced a product valued at §347,472, while the product of the ([uarries operated in 19ol amounted to $24t],6.S5. The red sandstones of Fond du Lac are the most valuable in the state and closely resemble the Connecticut bi'ownstone, though harder and firmer. These quarries were not operated during the vear covered by this report. GraniteK. — More thiin half the state is underlaid b}' the crystalline class of rocks to which granite belongs. There are large exposures of granite in the northern part of the state which are practically of little value because of their inaccessibility. Those in the southern and western part are of more importance. The first quarry was operated in 1868 in Sherliurne county. Minnesota granites are both red and gray in color and vary as to fineness of their grain. ^ The value of the product fiom the 27 granite quar- ries operating in 1902 was $478,989. These (juarries were located in Benton, Bigstone, Lac (jui Parle, Red- wood, Renville, St. Louis, Sherburne, and Stearns counties. I'rieioiix stones. — The value of the catlinite, or red pipestone, quarried in Pipestone county in 1902 was $2,000. This is found nowhere else in the world; is blood red. easily carved, and susceptible of a dull polish. It is famous on account of its earlier use bv the Indians for pipes and ornaments.' The value of the output of chlorastrolite. a nonlio- niogeneous metal found along the shores of Lake Su- perioi-, was $4,000; that of agate, found in the ,suid and gravel around the city of St. Paul, $1,000, and that of mesolite, $1,000. ■' Stdnea for BnildiiiK ami I>('Corati wage-earners, who received |69,47ti,7lt5 in wages.

Lead and zine ore. — The print'ipal lead and zinc ore producing districts of Missouri tire the southeastern, central, and southwestern. In the southeastern dis- trict, including the counties of Jeti'erson, Madiso.i, kSt. Francois, and Washington, where lead alone is pro- duced, the ore.s occur in the older Paleozoic limestones and have veiy little zinc associated with them. They are disseminated in small grains through the solid lime- stone, and to distinguish between them luid the concen- trated ores of the southwest they are called dissemi- nated ores.^ In the central district but little has been done toward developing lead ore mining. In the south- western region, commonly known as the Joplin district, which extends into the adjoining corners of Arkansas, Indian Territory, and Kan.sas, the lead ores occur in connection with zinc, and are found in crevices and cavities in irregular deposits, but at the present time the production of zinc ore in this district is far greater than that of lead. Ill 1705 an expedition prepared by the governor of Louisiana ascended as far north as the mouth of the Kansas river in search of precious metals.'^ The cele- brated Mine La Motte was discovered in 1716 by M. de la Motte Cadillac.^ In 1719 the Sieur de Lochon com- 1 The Mineral Industry, 1894, Vol. Ill, page 405.

In 1763 Francis Burton discovered the lich mines now known as the Potosi mines.* The first regular shaft was sunk in the Meramec or southea.stern district in 1798,* and this district has since continued to be a large producer of lead ore. The lead and zinc ore deposits of southwestern Mis- souri were discovered in 1851,* since which time they have been continuously worked, with the exception of an interruption during the Civil War. In 1872* the zinc ore, associated with the lead found in this district, began to attract attention, and has now become more important than the lead ore. In 1902, only lead ore was produced in Douglas, Franklin, Madison, Miller, Morgan, and St. Francois counties; only zinc ore was produced in Howell, Ozark, and Wright counties; and both ores were produced in Benton, Cole, Greene, Jasper, Jefi'er.son, Lawrence, Moniteau, Newton, and Washington counties. St. Francois count}' is the largest producer of lead ore in Missouri; in 1902 its output was 83,4(;)1 short ton.s, valued at $3,584,307, about 67 j^er cent of the total lead ore production of the state for 1902. Of the 8 operators in this county, 7 had each an output valued in excess of $100,000 and 1 in excess of $1,000,000. Jasper and Newton counties are also very large pro- ducers of lead and zinc ores, 39 mines each exceeding $50,000 ill value of output. The following table shows the annual production of lead and zinc ores in Missouri to the present time: Table 4. — Annual production of lead and :inc ore: 1873 to 190i. \V.\R.

As the state sutlers from the dis- advantage of i)eing surrounded by other coal producing .states whose product can be mined moi-e cheajily, it has to depend very hirgely upon local markets, and any increased production should therefore lie considered as indicating a growth in local population and industry.

Foremost among the minerals in Montana is copper, in the production of which the state leads the world. Millions of dollars worth of gold and silver have been mined since the discovery of gold in the state in 1852. Bituminous coal in large quantities is found along the Missouri and Yellow.stone rivers.' Dej^osits of iron ore, of lead and zinc ores, of graph- ite and of manganese ore have been found in the state, and have been mined to a greater or less extent. The rocks of the state include granites, sandstones, marbles, and limestones in great abundance and variety. Corun- dum, flint, quicksilver, tin, platinum, tungsten, and stones suitable for grindstones are also found, and the Montana .sapphire is well known among the precious stones. Of the total value of the product of the mines and quarries in the state in m02 copper ore contributed 72. H per cent, more than four times the value of any other mineral produced. Besides those shown in Table 1, the following minerals occur in the state, but were not commercially produced in 1902: Tin, tungsten, cinnabar, lead and zinc ores, platinum, molybdenum, clay, petroleum, and magnesia. In addition to the active mines and (juarries shown in the foregoing table, 128 operators reported development work in 129 mines and quarries, distributed as follows: Gold and silver, 126; Vjituminous coal, corundum and emery, and marble, 1 each. The operators employed 77 salariefl officials, clerks, etc., who received '|8;:5,01>9, and 520 wage-earners who were paid $592,626 in wages.

Copper ore. —The city of Butte dates from the dis- covery in 1864 of placer mines in the Missoula gulch. The placers were in no way remarlvable, being dupli- cated elsewhere in neighboring camps. Following the exhaustion of the auriferous gravels, came the discovery and working of silver bearing ledges in the hills, but these did not add materially to the fame of the district. The Anaconda mine and others of the great properties were bought, developed, and worked with a view to their silver values.' The opening of the Anaconda as a copper mine dates from 1882. At that time the dark i-ed and brown quartz, developed for its gold and silver values, carried only traces of copper, and it was while preparing to mill this ore that the main shaft then being sunk entered the rich copper ledge at a depth of about 300 feet. This led to other discoveries.' In 1870 the Lake Superior I'egion produced 87.2 per cent of the copper product of the country. In 187.5 the Lake product constituted 89.4 per cent, and in 1880 it was over 82.2 per cent. In 1882 Montana commenced to produce and advanced steadily and rapidly until in 1887 its copper output exceeded that of the Lake Supe- rior mines. Since that date, with the single exception of 1891, it has held first place not onl}- among the states and territories, but as the largest copper producing dis- trict in the world. The following table shows the annual production of copper in Montana from 1883 to 1902: 1 Bancroft's History of the Pacific States, page 589 ff. YEAR. Long tons. YEAR.

Gold and silver. — Although the presence of gold in this section was probably known to the mi.ssionaries, they had other motives than the gathering of precious treasures. The discovery of gold is, therefore, appar- ently due to Francois Finlay, a French half-breed, who bad worked in the placers of California, and when returning to the vicinity of his former home, discovered tine float gold on Gold creek, in Deerlodge countv, on the western slope of the Rockj^ mountains. He did little more than prospect the locality. - Subse({uently, in May, 18.58, James and Granville Stuart, Thomas Adams, and Reese Anderson jsrospected in Gold creek, finding dirt or gravel that showed as high as 10 cents to the pan. They were forced to abandon the work, however, because of trouble with the Indians and lack of tools and provisions. In the summer of 1860 three small sluice boxes, roughly hewed out of green timber, were operated on Gold creek by Henry Thomas. This was the first actual mining in Montana. Stuart and his party had removed to the vicinity of Fort Bridger, where they lived as traders until 1860. when they returned to investigate the affluents to the valley of the Deerlodge. They prospected during 1861 and found several favorable localities, but it was not until 1862, after receiving from Wallawalla, Wash., 425 miles distant, tools and lumber, that the first string of 1<» sluices was set up and worked. They had communicated the news of their discovery to a relative at Pikes Peak, as Colorado was then called, and about the 20th of June, 1862, miners began to arrive at Deerlodge in consider- able numbers. The newcomers discovered the placers at Pikes Peak gulch. Pioneer gulch, etc., and from this time the immigration of gold seekers rapidly increased.' ^ Mineral Resources of the United States East of the Rocky Mountains, by .James W. Taylor, 1868, pages 39 and 40. ^ Ibid., pages 39 to 51. 250 MINES AND OUARRIES. Alder o-ulch, in Madison county, was discoN'cred in the spring- of 1863 b}^ William Fairweather, one of a party of prospectors from Bannock city. The first pan of earth yielded $1.75. Being without proyisions, the party hurried back to Bannock city, and returning- with friends the gulch was staked off on the 6th and 7th of June, 1S63. Within less than two j-ears Alder gulch contained tiyethriying towns, besides Virginia City, an incorporated city of nearly 10,(X)0 inhabitants. This was the richest and largest "tind" eyer worked in Montana, and probably in the world, being nearly 20 miles in length and uniformly productiye throughout the greater portion. At the head of the gulch the gold was coarse, and many nuggets were picked up yarying in yalue from $2(10 to $800.' The discoyery of Last Chance gulch, near the site of the present city of Helena, in the summer of 1864 was the next of importance. In that summer a party of tiye or six men are said to haye taken from one of the bars in Confederate gulch about 1,400 pounds of gold dust of a value of nearly $300,000. In addition to the foregoing there were numerous rich diggings found both east and west of the main range. The location and working of yein mines dates from 1864. The Oro Cache lead in the sunuiiit district of Alder gulch was discoyered early in that year, and work was begun on December 1 of the same year. The Whitlatch Union lead, sometimes called the Owyhee, was discovered in the winter of 1864, and work was begun the succeeding spring.' The following table, compiled from various sources, shows the value of the annual gold and silver production in Montana from 1862 to 1889.

(Jixd^ hituiivinouH. — The occurrence of good steam coal accessible to the Northern Pacific system was a question of importunce in the development of the mining 'Mineral ResourceK uf the (Inited .Statew Eawt nf tin Mountains', 18(i8, pages \','r\ tn .51 . Ko('k\ and manufacturing intere.sts of the Northwest. A vast amount of lignite was known and in places worked, but was so poor in quality that coal was brought from Pitts- burg to mix with it. In ISSl true bitimiinous was known to occur in l)ut two jjlaces in Montana, one near Bozeman canyon and the other on the summit of Mul- lens Pass. In that j'car, taking these occurrences as clews, the Bozeman outcroppings were traced several miles. Another outcrop was found for 24 miles, south of Wilkeson through the forests of the Cascade moun- tains, and sevei-al other less important bituminous fields were discovered. The bituminous coal field north of the fort^'-fifth parallel is on the west tiank of the Cas- cade and the east flank of the Rock}- mountains, the few occurrences between these ranges being insignificant. The great plains for miles away from the mountains are luiderlaid with beds of lignite of inferior quality, often attaining a thickness of 7 or 8 feet. As the moun- tains are approached the lignite, as a rule, disappears, giving place to true bituminous, and freciuentlj' a good coking coal, though the seams are of less thickness than the lignite.' The production of coal in the Bozeman field began in January, 1883, and operators in the Gardiner field, along the Yellowstone, in Gallatin county, reported their fir.st production the same j'ear.^ The following table, compiled from the reports of the United States Geological Survej^, shows the annual pro- duction of coal in Montana from 1883 to 1902: Table 0. — .imniiil prorliiction of coal, hituminous: 1SS3 to 190:i.

Pi'i'cloim ufancx. — The only sj'stematic mining that has been undertaken for sapphires is in Montana. Sapphires were first found in this state b}^ miners who were washing the gravels of the bars on the Missouri river for gold. The.se were finst described in 1873, but actual mining did not begin until 1891. These bars are located from 12 to 18 miles northeast of Helena and ^ Tenth Cenaus, Vol. XV, pages 691 anci 692. ■'United States Geological Survey, "Mineral ReMdurces Ihiited State.s," 1883, page 53. if the MONTANA. 251 ha\c liooii followed from Canyon Ferry to Ainericaii l)ar, ii (listiince of altout 1^ mik's. Sapphires are also found m the gravel of Maple g-nlcli, about 1 mile above Pjnier- ald liar, the intermediate gravels being barren. These stones are for the most part of a pale green or greenish yellow color, with an oecasional pink and yellow, while those approaeking a red or blue coloi' are ex- treuH'ly rare. Sappkire kiis also been found at Rock creek. Cottonwood creek, and Yogo gulck. From tkese deposits stones of deeper color kave l)een obtained, those from Kock and Cottonwood creeks rano'lni;- from red to blue, and those from Yogo giilch being all blue.' Smoky quartz has also been found at Three Mile gulcli, near Helena. A gigantic crystal weighing 93i pounds was found on Clear creek, in Jetierson county. Mon- tana is the chief western source of supply for the ame- thyst. In 1895 a crystal weighing 1^ pounds was found on Granite creek, and in 1»0(» remarkable discoveries were made in Jefferson county about 22 miles southeast of Butte. The ametliyst in this locality occurs in tine crystals curiously mingled with quartz. The amethyst itself is free from foreign substances, though occasion- ally parts of the same crystals are composed of tour- maline. Besides those already named, beryl, aquamarine, gar- net, chrysoberyl, white topaz, opal, agate, and moss agate are frequently found' in the gold ))earing gidch soils." Limestones and dolomitea. — Though the occurrence of limestone is known in almost every one of the 21) coun- ties and the Crow reservation, onh" 8 reported the quar- rying of limestone in 1902. The largest product was shown for Cascade county and the second largest for Jefferson county, their entire production being used as blast furnace flux. Lewis and Clarke county was third, where about one-fourtli of the production was used for building, more than one-half for blast furnace flux, and the remainder for flagging. Powell countj^ was fourth, the entire production being burned into lime. The fifth countjr in value of product is Flathead, followed by Park, Sweet Grass, and Yellowstone in the order named. Of the total production in the state, $88,000 was used for flux; $8,775 for lime burned; $6,375 for building purposes; and the remainder for flagg-ing and rubble. Sandstones and quartzites. — A tine light gray sand- stone, somewhat resembling the Berea, Ohio, stone, occurs in considerable abundance in Rocky canyon, Gallatin county, the formation permitting the removal of large blocks which work readily when tirst removed, but harden on exposure. A compact, red quartzite, found near Salesville, in the same county, and a tine, very light stone quarried near Dillon, in Beavei-head coiuity, are coming into use.'' Sandstone also forms one of the strata of the (!oal Measui-es of Montana, often cleaving the coal seam and sometimes attaining a thick- ness of 50 feet.' In 1902 Yellowstone county showed the largest pro- duction, |62,1()L^ The amount used for building pur- poses was $54,430, of which $51,<)38 was the value of dressed stone. The other' counties reporting were Cas- cade and Flathead. Sll H'fjnix (■ryda,llme rochii. — A tine grained light gray granite occurs in Lewis and Clarke county, and a coarse hornblende-mica granite is found in the copper region near Butte. This latter rock is of good (Quality, but requires careful selection, as those portions in close proximity to the ore veins are charged with pyrite, which oxidizes on exposui'e. There is abundance of granite in the state, but for lack of a market (juarrying is not extensive.'' Two of the three quarries reporting in 1902 were located in Lewis and Clarke county, and the third in Jefi'erson county, the total output being valued at $77,050. Almost the entire production from Lewis and Clarke county was dressed for building purposes. Of the total production the value of stone for building purposes amounted to $32,600, and that used for riprap to $43,800. All other minerals. — The property of the Montana Corundum Company, consisting of four claims and the mineral rights in 3,000 acres of land, was located in 1901. The ground upon which the corundum was dis- covered has been used as a stock i-auge for nearly thirty 3'ears, and no doubt in the last ten years hundreds of people have passed over the "float" crystals without stopi)ing to inquire their nature. A farmer and pros- pector exhibited, in the winter of 1900-1901, to a druggist from Hoopston, 111., a crystal and a pocket- knife, the blade of which gave evidence of the hardness of the crystal found. The druggist recognized the mineral, and after a careful search of the vicinity where the crystal was found detinitely located the vein. A shaft 85 feet deep was sunk, from the bottom of which a drift was run along the vein — to the west 165 feet and to the east 72 feet. The vein thus far developed meas- ures from 26 to 48 inches between the walls, with a pav gtreak varying from 14 to 42 inches in width. Numer- ous shafts, surface crosscuts, and pits have prospected the vein for a distance of over \\ miles." In 1902 one flint quarrj' was reported as in operation near Basin, in Jeffei'son count}-, the entire production being sold crude as a flux in metallurgical operations. 1 Bureau of Agriculture, Eighth Bieunial Keport, 1902, "Lahor _and ludustry of Montana," pages 312 to 320. 2 History of the Pacific States, by Hubert H.

Prior to 1887 a deposit of graphite was discovered in Van Camps canj'on, 18 miles from Dillon, but it was not s}^stematically developed until 1901. The vein is a true fissure, and varies in width from 12 inches to a few feet. The ore has been tested and declared equal to the best grades imported from Cejdon.' The sandstone quarries at Columbus, Yellowstone county, reported a portion of their product as manu- factured into grindstones. It is a line even-grained sandstone, and produces an article equal to the well- known Berea grindstone." Gypsum was discovered in 1893, in Carbon county, 8 miles from Bridger, the nearest railroad station, which is 29 miles from Billings on the main line of the North- ern Pacific. Active development began in 1894, and in spite of the long haul by wagon the gypsum has been placed in successful competition with the eastern prod- uct. The deposit, from 2 to 10 feet thick, lies almost flat, about .30 feet below the surface of the ground. In 1900 another quarry was opened in Cascade county; the gypsum vein is about 16 feet thick and lies flat under several feet of limestone. The n)ill of this plant is 'Bureau of Agriculture, Eighth fjiennial Report, "Lalxjr and Industry of Montana," page 467. ^ Ibid., page 465. located on a branch of the Montana Central Railway; the mine being directly back and up the hill, gravity is largely helpful in handling the rock.^ The work of the Northern Transcontinental Survey proved the existence of extensive deposits of iron ore in the mountain region of Montana. Notable among these is a mass of magnetic ore on East Boulder creek, Gallatin county, and on Cable mountain in Deerlodge county. The ore from the latter locality will average from 5.5 to 60 per cent metallic iron, is low in phos- phorus and sulphur and practically free from titanium.* In previous years the state has been comparatively unimportant as far as the production of manganese ore is concerned. In 1902, 9,000 tons of ore were mined, and stocked at the mines, from two deposits in Jeffer- son county. Analysis of the ore is said to show 4.5 per cent and over of manganese. It would also be valuable as a flux.' About 5 miles southwest of the city of Helena a vast ledge of marble containing several grades of this min- eral lias been located.

Of chief importance among the natural resources of Nebraska are its rocks of various kinds and qualities. Sandstone, chalk rock, limestone, and magnesia rock abound. Fire and mineral cla3'S are of extensive occur- rence in the northern counties, and a fuller's earth of superior quality was discovered in Cherry county a few years ago. ^ Bituminous and lignite coal underlie the eastern counties and the valley of the Repulilican river. These beds furnish fuel for local use, but up to the present time the deposits have not been worked com- mercially.^ Table 2 shows the value of the products of the man- ufacturing industries of Nebraska, based primarily upon minerals mined and quarried, as well as the value of all manufactured products of the state, as reported at the census of 1900.

Hervey, page 6. ■' King's Handbook of the United States, page 526. upon minerals mined and quarried, was $32,101,246, or 22.3 per cent of the total. The value of the output of the mines and quarries of Nebraska in 1902 was $148,391, or al)out one-tenth of 1 per cent of the value of all its manufactured products in 1900. The average number of wage-earners engaged in manufactures in Nebraska in 1900, as reported at the Twelfth Cen.sus, was 24,461, and the wages paid them amounted to $11,570,688. The average number of wage-earners engaged in mining and quarrying in 1902 was 178, and the wages paid them amounted to $95,935. The combined figures give 24,639, as the number of wage-earners, and $11,666,623 as the wages paid in the combined industries. Manufactures employed 99.3 per cent of the wage-earners, and paid 99.2 per cent of the wages; while mines and quarries employed onlj' seven- tenths of 1 per cent of the wage-earners and paid eight- tenths of 1 per cent of the wages.

The discovery and cievelopment of mineral deposits, especially that of the Comstock lode, is respi msible for the settlement and indeed the veiy existence of Nevada, and the historj' of mining is therefore to a great extent the history of the state.' Until the news of precious metid discoveries and the consequent inilux of prospectors, Nevada was largely a desert wilderness, invaded only bj' missionaries and a few dauntless exploring parties. The early hi.story is to a certain extent identified with that of Utah. Arizona, portions of Colorado, Wyoming, Oregon, and northern Ualifornia,- and it wa.s not until March 2, 18()1, that the confines were fully estahlished and Nevada took position as a recognizefl territory, advancing to statehood October 31, 1S64. Certain minerals occui' in considerable tjiiantities in various portions of the state, for whicli no cdinmercial production was shown for 1902. Among the most important of these are baryte.s (heavy sptir), found in Humboldt c(junty, coal in the form of lignite, in Esmeralda county: cinnabar, the ore containing ((uick- silver, near .Steamboat, in Washoe county; graphite or plumbago and magnetic iron ore (magnetite), in Humboldt county; iron ore (hematite), in Elko and Churchill counties; iron sulphuret (pyi'itc), in Lan- der and many other counties; cerussite (lead car- bonate) and galenite, in Eureka county; pyi'olusite oi- manganese dioxide, at Dun (Jlen and near (iolconda, in ' Ili.story nf .N'l^vHila, fiy Hubert IJ.

Ill addition to the productive mines and (juarries in Table 1, development work, confined to gold and silver, was reported by S2 operators. During ll.t(t2 these operators employed .574 wage-earners and paid $6.56,169 in wages. The 112 salaried officials, clerks, etc., received $181,172; the contract work amounted to $27,13.3; the miscellaneous expenses to $70,43.5; and the cost of supplies and materials to $454,077. The manufacturing industries of a state depend somewhat upon the character of its mineral deposits, H(.)nie of the most important manufactured products l)eing based primarily upon matei'ials obtained in mines and quai'ries.

Tlif ^'allies given As seen from Table 3, the production of gold during 189S was greater than that of any other year .shown, and the product during 1.S97. 1.S9S, and 1901 was slightly more than that reported for 1902. Both the quantity and value of silver produced in 1902 were greater than for any other year since 1S9(), in which year and in earlier years a larger production is reported. The smallest production of gold was reported in 1.S93 and of silver in 1S98. Gold was discovered in Nevada in Gold canyon, near Dayton, by Abner Blackburn, in July, 1849.' In the same year an immigrant named Hardin discovered silver in the Black Kock range, in Humboldt county. ' Other placer and quartz mines were located in \-arious parts of what is now Nevada, but Gold Canyon was the only district worked jirior to 18.57. The Comstock lode of gold and silver ore was discovered June 11, 1.S59. and from this time on the mining interests of Nevada have been a matter of brilliant history.* The gold hunters, working up the ravines from Gold canyon and Six Mile canyon, in 18r)9 came across what is known as the ^'Comstock lode," so named for Henry Conistock, one of the claim locators. This famous channel of silver and gold ore is about 3 or 4 miles long 'Annual Report of the Director of the Mint, 190L', pa^'e 152. -Harper's Encyclopedia, Vol. IX, jiajie 434. ^Hi.storj' of Nevada, page 103. *Il)id., pages 94 and H.5. and a quarter of a mile wide, and extends nearly north and south along the eastern slope of Mt. Davidson, principally in Storey county, at a distance of about 20 miles from the C-alifornia boundary. At tirst the ore in the Comstock lode was worked for gold alone, but later the black metallic substance occurring so persist- ently in connection with the gold was discovered to be a rich sulphuret of silver.'' From that time on until 1877 this locality was in- creasingly productive. Dui'ing the bonanza years — 1.S73 to 1877 — the value of the ore produced each month ranged from about $2.n()(X(,»00 to $3,000,000.

The Sutro tunnel, projected b}' Adolph Sutro in 1869 and finished in ISTl), is nearly 4 miles long, extending from the low hills bordering Carson ri\'er valley' west- ward to the Comstock lode. The chief objects of the tunnel were to improve the drainage and ventilation and facilitate the working of the Comstock lode, and for this service all the mining companies pay a royalty. This tunnel has lieen principally valuable in drainage, and without it certain of the deep workings of the lode coidd not have been operated successfully on account of the flooding of the lower levels of the mines. Quartz and porphyry are generally the accompany- ing vein matter met with in the Comstock lode, the gangue carr3'ing the precious metals being quartz and the inclosing walls a diorite or syenite on the west and on the east a porphyrite or trachyte formation, seamed with quartz and clay. The ore obtained, both gold and silver, is free milling and is not refractor}' with foreign mineral complications. ^ The rich deposit of precious metals in the Tonapah mining district in the north central portion of Nye county, near Mt. Oddie, was discovered in April, l'.»()0, bj^ James L. Butler, and in August of the same year he located the eight claims now forming the regular Tonapah group. A plan of leasing the ground in small sections on a 2.5 per cent royalty was adopted by ]Mr. Butler and a considerable quantity of ore was extracted on this basis.- The following table, compiled from the reports of the Director of the ^lint, shows the quantity of the produc- tion of ore, and the value of its precious metal contents, in the Tonapah district for 1901 and 1902: Table 5. — Animal production of gold and silver in, the Tonapah dis- trict: 1901 and 190 it.

Prior to January, 1902, the work done was altogether individual, but in that year a systematic de\elopment of the propert}' was begun by a Philadelphia syndicate which had purchased the Tonapah mines. Several shafts have been started and the deep workings show an improvement both in the ({uantity and (juality of ore.'' The mining industry was considerably hampered by inadequate transportation facilities during these years. Food, supplies, and even drinking water had to be carted to the camp from other localities and the ore transported 60 miles to the' neai-est railroad.' A rail- road is now t)eing built to the mines. The Mizpah ledge has i-eceived the greatest amount of attention, although the surface indications point to rich deposits awaiting development in other of the fif- teen ledges thus far discovered in this group. The chutes in which the ore is found are sometimes from 6 to H feet and even more in thickness, and pitch to an angle of about 3.5". The gangue substance is quartz and the ore a fine grained black sulphuret, containing much chloride of silver and small amounts of iron and manganese. There is no free gold.* Sundi3 3<*4 108, 08.5, 914 30223—04- -17 1 Includes the products of 1 producer of chemicals and allied products in order to avoid disclosing its operations. This table shows that the value of all manufactures for New Hampshire in 1900 was $118,709,308, and that the value of manufactured products based primarily on the products of mines and quarries was $10,623,394, or 8.9 per cent of the total. Tables 1 and 2 also show that the combined value of manufactures for 1900 and of mineral products for 1902 was $119,885,620. Of this amount, manufactures contributed 99 per cent and mines and quarries 1 per cent. During 1902 there were employed in mines and quar- ries 1,253 wage-earners, who received $806,494 in wages. The census of 1900 reported 70,419 wage- earners emploj'ed in manufactures, at ^vages amounting to $27,620,247. On the basis of these figures, wage- earners engaged in manufactures constituted 98.3 per cent of the total number, and their wages amounted to 97.2 per cent of the total wages. It follows, therefore, that the wage-earners employed in mining industries constituted only 1.7 per cent of the total number em- plo3'ed and that they received 2.8 per cent of the wages. Siliceoiis ci'ystalline rochs. — Granite is found in every section of the state in quantities practicallj' inexhaust- ible.'' New Hampshire is one of the mo.st mountainous of the New England states. The AVhite mountains, extending through the upper half of the state, are prac- tically solid granite. As early as 1623 stone was used for building construction;* and judging from the fact that the first settlement was made in the vicinity of prominent granite deposits, it is reasonable to suppose » Report of New Hampshire Bureau of Labor, Vol. VI, 1901-2 page 16. " History of New^ Hampshire, by J. N. McClintock, page 29. (257) 258 MINES AND QUARRIES. that this stone was used. The old state prison, erected at Concord in 1812, and the statehouse, built in the same city in 1816-19, were built of this granite, quar- ried in the immediate vicinity.' The admirable state of pi'eservation of these buildings is evidence of the excellent quality of the stone. The New Hampshire granite is known to commerce as the muscovite-biotite granite, and is considered one of the most valuable in the United States. In texture it is as tine as many marbles, and is remarkable for the wonderful ease with which it can be worked. The Library of Congress at Washington is built of this stone. ' In the production of siliceous crystalline rocks, New Hampshire ranked fourth.^ The total production of this stone in the United States for 1902 was valued at $18,257,944. New Hampshire contributed a product valued at $1,147,097, or 6.3 per cent. The mineral industries of the state, according to Table 1, employed 1.253 wage-earners, with aggregate wages of $806,494. The wage-earners emplo\'ed in the production of siliceous crystalline rocks numbered 1,219, or 97.3 per cent of the total, and their wages amounted to $791,196, or 98.2 per cent of the total.

It will be observed that, while there has lieen a steady increase in value of products since 1895, previous to that date the industry experienced many fluctuations. The year 1902 was the first in which the value of the output exceeded $1,000,000. All otlier iniiierals. — Infusorial earth and tripoli are produced in New Hampshire in small quantities. Dur- ing 1902 the only deposit that was worked was on Troy mountain, in Cheshire county. The material, after it is mined, is calcined, bolted, and manufactured at Keene, by the producers of the raw material, into cleaning powders and polishers. During 1902 Cheshire county was the only producer of mica in commercial quantities, and was credited with two operators. Mica mines have been uncovered and worked at Grafton, Grafton county; at Dan bury, Merri- mack count}'; and at Alstead, in Cheshire county. The Ruggles mine, which up to 1889 had been a constant producer since 1803, at one time contributing four-hfths of the domestic mica, was idle during 1902. While the value of the state's production of mica in 1902 was not large, the state nevertheless ranked fourth, as the entire value of the output of mica in the United States amounted to only $118,849. The quarrying of various stones for manufacture into oilstones, whetstones, and scythestones has been an im- portant industry in New Hamp.shire ever since Isaac Pike discovered a superior grit for scythestones in Grafton countj- in 1823.'' The company formed to ex- ploit the deposits now owns and operates quarries in New Hampshire, Vermont, Indiana, Ma.ssachusetts, Ohio, and Arkansas, and has mills for cutting, smooth- ing, and mounting the stones. Special stones of many kinds are put upon the market, and the industry shows a steady growth.' During the census year there were discovered and sold a small number of beryl gems, classified as precious stones. These were all found in Grafton county and were not in anv case the result of svstematic search or mining. 'Stones for Building ami Decoration, by (ieorge P.

The mineral wealth of New Jersey constitutes one of its greatest resources, and since the earlie.'-t days of its histoiT has exerted a marked influence over its general industrial development. The most extensively utilized of the state's diversified mineral deposits is its clay, the exploitation of which has brought New Jersey into national prominence. Doubtless an important factoi' in their extensive development is their geographical occurrence. While brick clays are found in almost every .section, nearly all the rich clavs are in Middlesex county close to the navigable coast waters and the Raritan river.' The metalliferous ores are mainly limited to those of iron, zinc, and copper. Lead and silver occur, and although the former has been worked, it is now aban- doned, and the latter has not been found in sufiicient cjuantities to warrant mining. The occurrence of the ores of arsenic and nickel is chietiy of niineralogical importance; no dei^osits or veins of workable extent have been discovered.'^ The state from its earliest history has been an im- portant producer of high-grade iron ore. The ore is of the magnetic variety and has a higher value per ton than that produced in any other state.' In 1902 the out- put comprised over 26 per cent of the total yield of magnetic iron ore in the countrj'.' Zinc mining in the United States had its inception in New Jer.sey,' and for 'The New International Encyclopedia, Vol. XII, pages 104,5 and 1046. ^Geological Survey of New Jersej', 1900, page xxv. ^United States Geological Survey, "Mineral Resources of the United States," 1902, pages 43 and 67. *The New International Encyclopedia, Vol. XII, page 1045 ff. ° Production and Properties of Zinc, by Walter R. Ingalls, page 13. many j-ears the Inilk of the zinc (jre mined was drawn from its deposits. The state's output of Portland ce- ment in 19<»2 was approximately one-eighth of the total yield of the country. The sand deposits of southern New Jersey are of a cjuality that makes theni valuable in the manufacture of glass, and thej' have been util- ized for this purpose since pre-Revolutionary times." The state also possesses valuable deposits of granite and sandstone that have been extensively exploited, e^\ie- cially during recent years. The greater part of the granite product is of crushed stone, in the output of which New Jersey exceeded every other state in 19n2. Other minerals produced commercially in 1!)02 are marl, slate, and talc and soapstone. In addition to these, the range of mineral deposits in the state comprises, among those of known occurrence, though not mined in 1902. the following: Asbestos, barytes, coal (bituminous), copper ores, galena, garnet, infusorial earth, magnesia hydrate and carbonate, mar- ble, mica, plumbago, phosphate rock, sapphire, serpen- tine, and silver.' The total expenditure for development work in 1902 was $275.9.^)0. Of this amount, $272.2.50 was applied to developing the cement industry. The remainder, $3,700, was expended in the development of gold and silver and iron ore deposits. Work of an experimental char- acter was also prosecuted in connection with copper ores.

Iron crre. — The lirst recorded exploitation of the iron ores of New Jersey occurred in 1674 at Tinton Falls, near the town of Shrewsbury, in Monmouth county. The pioneer in the industry in the state was Heniy Leonard, who came from the village of Rowley, in Massachusetts, to New Jersey and established the iron manufacture in that state. Bog ore was used in the first furnace. Foi- more than a third of a century the industry of iron manufacture in the state, which grew rapidly from the start, wa.^ <'oiilinc(| to the \vorkin<-- of bog ore. Large quantities of iron were made from this ore at one time, and the industry of its mining and manufacture spread throughout southern and south- western New Jersey and was for more than a centurj' and a half an important factor in the industrial devel- opment of this part of the state. "Jersey pines" fur- nished the fuel for the furnaces and Idoomeries, and oyster shells supplied the tluxing material. The passing of bog ore mining was approximatelj' coincident with the supplanting c)f charcoal as a fuel by anthracite coal, which took place about 1840. The rich deposits of magnetite in northern New Jersey were discovered at an earh' day, and about 1710 settlements were made on Whippany river, in Morris county, for the purpose of smelting the iron ores in the neighborhood. Probably the lirst forge erected for the working of these magnetic ore deposits, which for almost two hundred years have been mined contin- uously, was located at a point alx)ut 4 miles northeast of Morristown. The celebrated Succasunna iron ore mine is near the place where the lirst forge was built. It was here that the pioneers in the industry obtained their ore, which was carried to the works in leather bags on pack horses; the bar iron was carried on horse- back over the Orange mountains to Newark. Other forges were soon built in Morristown and some in Essex county, all of which for a long time and with the same crude methods of transportation drew their ore from the same source. The ores were free to all until the tract embracing the Dickerson mine was taken up on account of its minerals by John Reading in 1713 or 1714. The deposit has long been known as the "Dickerson mine," from one of the early governors, who was subse(iueiitly a United States Senator. On March 10, 1714, Williimi P(>nn, by a warrant from the council of proprietors, acijuired title to one of the richest iron ore mines in New Jersey. This tract was situated in Essex county, then Hunterdon, and was the site of what later was known as the celel)rated Andover mine. The products of this mine were for many years carried on pack horses and in carts down the valley of the Museonetcong to a place on the Delaware called Durham, and thence transported by boat to Philadelphia. For some years after the beginning of the eighteenth century New Jersey wtis the only colony outside of New England engaged in the manufacture of iron, and this was largely confined to its bk)omeries. Not much progress was made in establishing the industry until about the middle of the eighteenth century; but from about 174(1 to the Revolution many blast furnaces and other iron works were erected, and the ii-on industry, though hampered to some extent by restrictions imposed by England, was exceedingly active. The patriotic cause was afterwards greatly indebted for much of its iron and steel, so necessary to secure its success, to the enterprises built up between 174(1 and 1770 within the borders of New Jersey. The t)ld t)\ford furnace, in NEW JERSEY. 261 ^^"arl•en county, built by Jonathan Robeson in 1742, is, according to tradition, tlae first one blown by a water blast. In 1880 it was still in operation, sharing with the Cornwall furnace in Pennsylvania the distinction of being the oldest furnace in the United States then in active operation.' In 1790 the total jjroduction of iroTi ore in New Jer- sey was 10,000 tons. Forty years later it had increased to 20,000 tons, and in 1855 had reached a total of 1(I(»,(H)0 tons. The output increased rapidly for almost two decades thereafter and in 1873 amounted to 665,000 tons. During- the succeeding three or four years there was a marked decrease, the output in 1870 dropping to 285,000 tons. Then ensued another period of rapid increase, which continued throughout the remaining years of the decade, the maximum output in the history of the state, nearly 1.000,000 tons, being reached in 1882. During the next ten years the annual production remained stead}-, with only slight variations, at an average of about 500,000 tons. Between 1893 and 1897 the pro- duction reached the lowest figures since 1861, with a minimum output for the period of 257,235 tons in 1897." The increase which was shown in 1898 has grown rapidlj' during each j-ear since, closing with an output of 111, 879' tons in 1902. This is a gratifying yield in view of the shortage of anthracite coal during the (dosing months of the year, which tended to retard the work of blast furnaces, and thus indirectly to affect the output of the mines. ^ The iron ore producing district of New Jersey is a continuation of the ridge of Archean rock which, beginning in Putnam county, N. Y.. extends southwest across Orange county, N. Y., and the Hudson river and, traversing northern New Jersey, runs out in Pennsyl- vania. Lenses of magnetic ore occur throughout its entire length. In New Jersey these are not as large as in the Adirondacks, but they are more regularly dis- tributed. Four courses or mine belts are recognized in the state — the Ramapo, the Passaic, the Musconetcong, and the Request — in order from east to west.* Mining operations, which began in Morris county, have extended until at present they are widely distributed over the belt, the principal points of production being at Mt. Pleasant and Hibernia." The following table shows the annual production, in long tons, of iron ore from 1890 to 1902: Table -i. — Aiiinuil proihii-linii nf Iron on.- ls:iii to 1902.

The inci-ease began in 1898, wdien the value of the output was nearly 50 per cent greater than thtitof L.S97." The maximum was reached in 1900, New Jersey then standing third among the states in the production of stones of tliis classification, with an output valued at more than fl.OOo.OOO.' The production has remained close to this figure .since. The bulk of the state's yield of this classification consists of trappean rocks u.sed principtdly as i-oad materials." The belt within which occur all the granitic and gneissoid rocks enters New Jersey from New York near the Ramapo river, in Bergen county, and traverses the state in a southwesterly direction. The greatest width of the belt is less than 20 miles, while it is less than half that width at its southern extremity. Compara- tively few quarries are worked throughout this area, though in many places the rocks are so situated that their exploitation is practicable at a relatively low cost. From the quarries at Dover, in Morris county, large quantities of .stone for railroad construction have been taken. A good quality of granite of fine grain and even texture occurs in the Vernon valley along the east- ei-n foot of Pochuck mountain." (Jay. — The valuable clay beds of New Jersey have been known and exploited for more than a century; but their extensive occurrence and great importance to the state and the country have been understood and fully appreciated for only a comparatively short time. The first recorded instance of clay mining in the state was in the l.)anks of South Ambo}'. The clay was used in making stoneware at Van Wickle's pottery at Oldbridge, now Herbertsville, about 1800. Ln 1802 a second pottery was built at Sayreville. on the Raritan, and began the manufacture of stoneware from the same clay banks at South Aniboy.

The famous fii-e clays of the stato were first exploited after the War of isli, probalil.y about isifi. At about this date G. W. Price carried to Boston a boat load of tire clay, dug- at AVoodbridye, from the afterwards celebrated banks, and maiuifactured it into tire biick. Jacob Felt, about 1820, mined and carried to Boston another shipment consisting of bO tons, for which he paid 25 cents per ton in the ground. From this begin- ning the mining and shipping of these clays to the same point continued for many years. In 1835 they were used in Philadelphia by Howell & Bros, in the manufac- ture of wall paper. The industry of tire brick manufacture within the state had its inception in lS/^>3, Air. J. It. AA'atson, of Perth Amboy, building and operating the first plant. By this time the clay deposits were beginning to attract some attention. The Gazetteer of New Jersey stated in an issue of 1833 that " extensive beds of white pipe clay, composed principalh^ of alumina, and infusible, have been observed between Woodbridge and Amboy." In 1840 Professor Rogers published in his final report on the Geology of New Jersey the results of a cursory examination made by him of the cla}' deposits, especially in the \icinit_v of Woodbridge. but these researches disclosed only a fraction of the full importance of the beds. During the following- fifteen 3'ears the scope of the clay working industries was materially broadened. The progress is indicated by the following quotation from the State Cieological Report of 1855: ^'Clay for making 5 those at Conrad, in Gloucester county, and at Wheatland, in Ocean county. Of these three groups of clay deposits those of the Middlesex district are l>y far the most important, being superior in ((uality and yielding an aggregate product many times larger than that of the I'est of the state combined.' Clay mining as a distinct industry disassociated from the manufacture of clay products has reached a fuller development in New Jersey than elsewhere in the country, this state, in 1902, contributing almost 34 per cent of the total product of the United States.^ Sitiidxtiiiiis (I lid qiKrrtsiti'K. — Sandstone has been quar- ried in New Jersey from an early date, especially in Bergen, Passaic, and Essex counties, for building- purposes, and for monuments and tombstones, and has pro\'ed thoroughly durable.

This limestone, known in the market as marble, was of a gra3dsh hue and in places banded, owing to alternate lines of light and dark minerals. It was worked mainly for the Pennsyl- vania market. A ver3' beautiful limestone, known commercially as "Rose Crvstal Marble," has been tpiar- ried to some extent on a subordinate ridge of the Jenn v Jump mountain range, in the same county.

The mineral resources of the state are varied, '2S dif- ferent minerals contributino- to the state's output in 1902. Among the variou,s branches of the mining indus- try in the .state the manufacture of cement is foremo.st. Both natural rock and Portland cement are produced in large quantitie,s; and New York has led the states for niany years in the production of natural rock cement. The greater part of the cry,stalline graphite production in the United States comes from the mines at Ticon- deroga, in Essex county, where the mineral has been mined for nearly a century. The gypsum deposits of the state are extensive, and in gypsum mining New York ranks fourth. The glass sand found in the state occurs in a form sufficiently disintegrated to require no further crushing before using it in the manufacture of glass.' The corundum and emery mines near Peekskill are among the largest producers of these abrasive materials in the United States, and in the production of garnet ' United States Geological Survey, "United States," 1902, page 1010.

Most of the buhrstones made in the United States are from the quarries of the state along the eastern slopes of the Appalachian mountains. The ,state for many years has been a large producer of tibrou^alc, most of which is used in paper making. Extensive deposits of clays are widely scattered and many of them are capable of being used in the manufacture of terra cotta, rooting tile, and the coarser grades of pottery.'^ Natural gas is also found over a very large area of the state. It was first used as a source of light and heat at Fredonia, Chau- tauqua countv, in 1821.'' The oil territory in New York is a continuation of the Bradford, Pa., field and has lieen more or less productive .since 1865.* With the excep- tion of Pennsylvania, New York state is the largest producer of the magnetite variety of iron ore. which ■■'New York State Museum, Bulletin No. 12, page 98.

Iron ores of both the red and bi'own hematite \'ariety are also mined in the state, and in a number of localities ore of the hematite variety is found suitable for metallic paint, and is also used for coloring matter in making mortar. The numerous quarries of the state produce annuallj^ large and valuable quantities of fine stones, among which are included the granite of the Adirondack region, the sandstones of Potsdam and Medina, the bluestone of the Hudson valley, the shell limestone of Lockport, the black marble of Glens Falls, the red marble of War- wick, the verd antique of Moriah, the rooling slate of Washington, Kensselaer, and Columbia counties, and the white marble of Westchester." Other minerals mined or quarried in the state in greater or less quantities are crystalline quartz, feld- spar, flint, infusorial earth, lead and zinc ore, and sienna. The following minerals also occur in the state, but were not produced in commercial quantities in 1902: Barytes, chrysoberyl, copper, fluorite, ilmenite, man- ganese, molybdenum, monazite, nickel, pyrope, rntile, serpentine, strontium ore, whetstones, mica, tourma- line, and sulphur and pyrite. In addition to the productive mines, quarries, and wells shown in Table 1. 6 operators reported mines and quarries having no production, the work done dur- ing 1902 being contined to development and care. These operators gave employment to 90 wage-earners on an average during the year and paid f.oO.iOS in wages. The 11 salaried officials, clerks, etc., received $16, .569; the contract work amounted to only $.500; the miscel- laneous expenses were $6,131; and the cost of supplies and materials was $2,164.

NEW YORK. 2 P. 9 Cement. — New York, which leads the states lu the manufacture of the Rosendale, or natural rock cement, i,s also the state in which the industry in this countrj'was first established. Natural-cement rock was lirst discov- ered in this country about 1818 at or near Chittenang-o, Madison t'ounty, N. Y., and was lirst used in the con- struction of the Erie canal.' In 1823, when the Ulster county section of the Delaware and Hudson canal was under construction, hydraulic-cement rock was disco\- ered near Rosendale." In 1825 a rock similar to the Chittenango variety was discovered at Highfalls, in Ulster countj', and the first crushing mill was erected there in 182ti. In 1828 a mill was ))uilt at Rosendale, in Ulster county- This locality soon became the lead- ing center for this industry, and has so remained.^ Ex- tensive works were also erected at Whiteport and at other places in the vicinity. Upon the completion of the canal activity in the manufacture of cement greatly declined, but upon the reopening of the old Snyder mill interest revived and the natural rock cement was made for the general market. Since 1839, when an exceptionally high grade of cement rock was found at Akron, in Erie county, an increasing industry has been maintained in that region.^ Certain strata of limestone were found near South Rondout, Ulster county, that are well adapted to the nianufacture of Portland cement, and suitable claj- for its production was also found near Phoenicia, in the same county. The following table, compiled from the reports of the United States Geological Survey, shows the annual production of both Portland and natural rock cement from 1890 to 1902: Table -Jt. — Amiiial production of cement: 1S90 tu I fin?.

It is also used largely for monuments, as well as for building and ornamental work, liecause it retains a good surface and polish and is believed to be durable.'' In the Lower Silurian formation at Plattsburg and Chazy, in Clinton county, two excellent varieties of colored marbles occur, which are commerciallj' known as "Lepanto" and ''French gra}'." The French gray has been used more extensively, with the po.ssible ex- ception of the Tennessee marble, than any other domes- tic marble for mantels, table tops, tiling, and general interior decorative work. ■' At Glens Falls, in AVarren county, there is an exten- sive deposit of dark Itlue-black magnesian limestone, certain strata of which furnish the finest varieties of black marble at jfresent quarried in this country. The stone is verv fine grained and compact, and when pol- ished is a deep, lustrous black in color, though the uniformity of the color is sometimes broken by the presence of a small white fossil. A beautiful coarsely crj^stalline marble of a carmine- red color, sometimes slightlj- mottled or veined with white, is found at Warwick, in Orange count}'. This stone has been but little used, and the supply reported is small. A peculiar granular stone, consisting of an intimate mixture of serpentine, dolomite, and calcite, inter- spersed with small flecks of phlogopite, has been quar- ried at Moriah and Port Henry, in Essex county, under the name of ophite marble. This stone is nearly free from the numerous dry seams and joints that prove so obiectionaV)le in most serpentines, and it can be obtained in sound blocks of fair size. The stone polishes well and is said to be durable. A stone of the same general nature has been quarried near Thurman,' in Warren county, and it occurs elsewhere in the same county. The largest and most valuable deposit of serpentine in the state is at Gouverneur, Fowler, and Edwards, in St. Lawrence county. The rock is massive and sound and remarkably free from the defects usually developed in rocks of this class. Near Pitcairn , in the same county, there is a fine deposit of serpentine of the variety com- monly called precious, and serpentine, from almost black to nearly white, forms the main range of hills on Staten Island. ■' The producing marble quarries of the state in 1902 numbered li, and were located in Clinton, Columbia Dutchess, St. Lawrence, Warren, and Westchester counties. The value of the marble quarried amounted to $577,298, an increase over 1901 of $198,139. Of the total, $267,013 was the value of the marble dressed for 'Stones for Building and Decoration, page .367. ■'Ibid., page 368.

Along the south- ern shores of Lake Ontario and Lake Erie are scat- tered a vast number of small wells, each Furnishing gas to from one to four families. In lyOiJ there were 612 productive gas wells the state, producing an output valued at $81:6,-171, an increase of $53,199 over 1901. (ti/jisinii. — The gypsum deposits extend in a narrow belt through the central part of the state in Madison, Onondaga, Caj'uga, Ontario, Monroe, Livingston, and Genesee counties. The l)ed near Union 8i)rings, in Cayuga county, was first opened in liS'28.' In a num))er of places the industry is onlj" of local importance, the product being used exclusively for land plaster, but there are some large plants which ]3roduce principally wall plaster. In 1902 the 17 productive plants produced 9.5,318 short tons, of which 60,184 was calcined into wall plaster and plaster of Paris. The entire product was valued at $259,170; that calcined into wall plaster at 1200,236. The state ranked fourth among the states in the pro- duction of this mineral.

' Slate. — Roofing slate has been found in many local- ities in the state and quarries have ))een opened in Orange, Dutchess, Columbia, Rensselaer, and Wash- ington counties. The only productive .slate quarries, however, are in a narrow belt lying entirely within Washington county. The stone varies in color from red and purple to green and is of excellent (|uality.- The 11 quarries productive in 1902, all in Washing- ton county, had an output valued at $126,718 — an increase of $25,758 over 1901. Garnet. — 'This mineral is found in Warren county, on the l)orders of the Adirondack region, and in Essex ' New York State Museum, Twentieth Report of the State < ieolo- gist, 1900, page rl80. -New York State Museum, Bullethi No. 15, pages 421 ami Vl'l. and St. Lawrence counties. The entire deposits in \Varren (■ounty appear to be of the common variety, almandine. It occurs in a formation (jf crystalline lime- stone and in gnei.ssic rocks which adjoin or are inter- calated with the crystalline limestone. Commercially this mineral is classified as massive garnet, shell garnet — the most valual)le for industrial [)urposes on account of its purity — and pocket garnet.'' The garnet is used almost exclusively in the manufacture of sandpaper, or garnet piiper, which is used for abrasive purpo.ses by manufacturers of boots and shoes and by wood manu- facturers. In 1902 garnet was mined commercially in Essex, AVari'en, and St. Lawrence counties, but the work done in St. Lawrence county was more or less experimental. The total production for the state in 19(»2 was 2,760 tons, valued at $97,600. As the total output of garnet in the United States for 1902 was 3,926 tons, valued at $132, S20, New York state produced 73.5 per cent in value of the entire product shown for the country. trrajihitr. — Deposits of graphite are known to exist throughout the Adirondack region, but the mining of crystalline graphite in this portion of the .state has been practically confined to a comparatively small section in the southeast portion of Essex county and in the north- east part of Warren county.* There are also occur- rences of graphite in Dutchess county and se^'eral tons have been obtained from them." The material in the mines near Ticonderoga, in Essex county, is in a vein of the purest foliated gi-aphite, sev- eral inches in width. The folia often have a radiated arrangement and are of considerable size. The gangue is calcareous spar, which sometimes exhibits large and perfect cleavages. At Johnsburg, in Warren county, the mineral occurs in irregular shaped masses, weighing from 1 to 20 pounds, in a vein of quartz.'"' Early in the last century, after the accidental discov- ery in 1815 of a deposit at Ticonderoga, in Essex countv, graphite mining was carried on, in a primitive manner, b}' the farmers owning the land, and the material, ground with considerable magnetic iron ore, was used for stove blacking.* In 1830 the invention of the lead pencil aroused in- creased interest in the Essex count}' mines. New open- ings were made in the mountain side and pencil leads were made from the crude graphite in the vicinitv of the mines. In 1863 the American Graphite Companj- acquired these properties, an extensive mill was erected, and the industry increased so rapidly that the annual production reached 50() tons in 1869. Subsequently the same company acquired the Warren county properties.* In 1902 the three productive mines of the state. ' New York State Museum, Bulletin No. 1.5, i^age.s 553 and 554.

As the total quantit}^ of this mineral mined in the United States in 190^ was 1,983 short tons, the contribution of New York state was 69.3 per cent of the whole. Corundiini and winery. — The emery mines of the state are located in Westchester county, near Peekskill. In most cases thej^ are abandoned iron mines, emerj- not having- been recognized when iron ore was ))eing- mined in this region. As the emery outcrops on the hillsides, the mines are usually shallow openings or quarries.' The output of the 3 mines productive in 19o2 was 2,886 tons, or 67.9 per cent of the production of corun- dum and emery for the United States. The value of the New York emery was fll:,625. Buhrstones and milivtoiiev. — In the United States the millstone varies from a sandstone to a quartz conglom- erate. The rock from which it is made occurs along the eastern slopes of the Appalachian mountains from New York to North Carolina and is known by various names. In New York state it is called " Esopus stone" and is found in Ulster county, in the Oneida conglom- erate. Millstones are now used extensively for grind- ing the coarser cereals, mineral paint ores, fertilizers, cement rock, barytes, and other minerals. Before the mtroduction of the roller process in milling, millstones were used prineipallj' in grinding wheat. The 22 operators of tlie state reported for 1902 a production of .5,1.58 stones, valued at §31t,570. All the quarries from which the rock was taken were in Ulster county. As the value of the liuhrstonesand millstones made in the United States in 1902 was $59,808, New York state alone furnished 66.2 per cent of this amount. ^1// other irdnercds. — Deposits of clay occur in nearly every county in the state, but the most important iire those of the Hudson vallev. This region is probablv 1 New York State iluseum, Nineteenth Report of the State Oeol- ogist, 1899, pages r 153 and ri54. the most active brickmaking region in the world. In 1902 its operators produced 782,932,000 common brick, or 73.7 per cent of the total output of common brick reported for the state. The production was exceeded by only two states. New York ranked lifth among the states in 1902 in the value of its products of cla}', which amounted to $8,411,113. The value of the clay mined and sold by the 7 operators in 1902 was $14,535. '' The crystalline quartz mined in Dutchess coimty in 1902 was used as a wood tiller. No statistics can be shown for the single operator of the state without dis- closing individual operations. The single productive feldspar mine of the stat<^ in 1902 was near Bedford, in Westchester county. The two productive Hint mines in the state in 1902 were both in Westchester county. The deposit of infusorial earth of W^hite Lake at Wil- miirt, in Herkimer county, is dug from the bottom of the lake, which covers about 4 acres, and has a thick- ness of from 2 to 31) feet, being covered by about 4 feet of water. ° As early as 1740 lead ore is said to have been mined in Dutchess county, and in both Columbia and St. Lawrence counties it was mined early in the last century. The presence of both lead and zinc was known in many other localities throughout the state, and much money was expended in the exploitation of this industry. * Only one mine, in St. Lawrence county, was productive in 1902. Under the classification "mineral pigments, crude,'' are the statistics for the production of oi'es used in the manufacture of mineral paints. Such ores were produced during 19(i2 in Cattaraugus, Rens- selaer, and Washington counties, but the entire output of the 5 mines was only 1.261 tons, valued at $4,251. The single productive pyrite mine in the state in 1902 was located in St. Lawrence county. 'United States Geological Survey, "Mineral Resources of the United States," 1902, pages 729, 748, and 769.

The state ranked fortj'-second in l'.to2 in the value of products of mines and quarries, with a total of $927,37(1. This small product (less than one-eighth of 1 per cent of the total for the United State.s) should not he taken, however, as a measure of the state's relative importance in cj^uantity and diversitj' of mineral resources. The minerals contributing to this tottd and arranged in the order of values were siliceous crystalline rocks, talc and soapstone, clay, gold and silver, mica, monazite, iron ore, barytes, bituminous coal, copper ore, limestones and dolomites, garnet, precious stones, sandstones and quartzites, buhrstones and millstones, and graphite. It will be noted that the production of gold and silver in 1902 was exceeded in value by that of siliceous crys- talline rocks and talc and soapstone, and almost equaled by that of mica and monazite. Also that copper and iron ore occupy relatively minor positions, while no yield of zinc ore was reported. These facts suggest the changing character of the state's mineral product and the somewhat checkered and interesting nature of its mining history. A number of minerals occurring in the state in com- mercial quantities were not produced in 1902. Asbes- tos has been found on Tr^'on mountain, Polk county, about 1|- miles west of Skj'uka. It is of the auiphibole variety and occurs in what is apparently a series of pockets, which have been traced across the country for nearly a mile. One pocket that was opened measured nearly 100 feet in width. It is of fair C|uality, and large masses have been taken out in which the fibei' was from 10 to lo inches long. The chromite mines of Yancey county give indications of containing large deposits, and there is a promising tleposit on Dark Ridge creek, in Jackson county. Another property recently de\'eloped is on Big Ivy creek, Buncombe county, 1(3 miles northwest from A.sheville. Several veins of the bla<'lv oxide of manganese of considerable extent have been found. Oil shale exists in great thickness in connection with the coal beds and yields a large percentage of oil.' Phosphatic deposits were first sj'stematically examined and studied in ISSA by the state survey. They were found to be of two classes. The first class consists of amorphous nodules, occurring in small quantities in Sampson, Pender, Onslow. Du- plin, Columbus, and New Hanover counties. These are of little value commercially. The other class is that of the phosphatic conglomerates found in l)eds of from 1 to (i feet thick, and located princ-ipally in New Han- over and Pender counties. While the percentage of phosphate of lime in these conglomerates does not average over 10 to 20 per cent, they have Ijeeii ground b}' several companies for local consumption." Grains of platinum have been discovered among the sands of gold washings in Kutherford and Burke counties, and > Handbook ni North (.'arolina, by L. L. Polk, page 129. ' Ele^'enth Cen!-U8, Report on jMineral Industries, page 690. (275) 276 MINES AND QUARRIES. also near Burnsville, in Yance^y county.' Nickel min- erals in small quantities are associated with many of the basic manganesium i-ocks. Genthite and garnierite have been found, bat thus far they have not been dis- covered in sufficient quantitj" to make them a commer- cial source of nickel. A deposit of nickel ore aver- aging 1.5 per cent of the metal is located near Morgan- ton, Burke county. Pyrite, which is one of the most common minerals in the state, is found especially in the counties of Catawba, Gaston, Chatham, Union, and Mecklenburg. ° Other minerals which have been found are: Epidote, ilmenite, manganese ore, manganiferous iron ore, mar- ble, rutilated c^uartz, rutile, sperrylite, tungsten, uranium, and vanadium. In addition to the productive mines and quarries of the state, extensive development work was carried on during 1902 on 29 nonproductive mines and quarries, the total outlay in this line amounting to §12(10,91.5. Most of this expenditure was applied to the develop- ment of gold and silver deposits, phosphate rock and clay sharing the remainder in the order named. The relative importance of those manufacturing in- dustries which are closelj' allied to or based upon the mining industry, using as their raw material the product of the mine or quarry, is shown in the following table: Table 2. — Manufactures based priiiiarilij iijimi the jirailtiets of mines and quarries: 1900.

Siliceous crystoUiiie rod's. — Granite and gneiss are among the commonest rocks of the state, being found in all sections except the coastward region. The prin- cipal producing counties where good grades of build- ing granites are found are Gaston, Iredell, Rowan, Surry, and Wilkes.'' Talc and soapstone. — Talc is a verj^ common mineral in North Carolina, both in the form of the impure greenLsh massive or slaty rock (potstone), used for monuments and for chimney and furnace hearths and linings, and in the form of a pure massive white stea- tite. The product for the year 1902 was reported from Cherokee, Moore, and Swain counties, and constituted 7.8 per cent of the total product of the United States. The most extensive beds of this mineral are found in Cherokee and Macon counties in immediate association with tlie marble range along the Nantahala, Valley, and Nottely ri\-ers.* CIiii/. — Many varieties of clay of varying value are found at many points in the state, especiallj' in Guil- ford, Chatham, Wake, Harnett, Robeson, Lenoir, and Jackson counties." In Jackson county extensive beds of kaolin of high grade have lieen found, and the total clay product of the state for 1902 came from this county. GoJd 0)1 d si I rev. — Gold was the principal product of the mines of this state for nearlj^ three-fourths of a century. It is widely distri))uted, but its principal field is the eastern slope of tlie Blue Ridge. Silver, on the whole, is a rare mineral in North Carolina. It has been obtained in considerable ciuantities at Silvei' Hill, in ^liffilogy of North Carolina, Vol. I, page 271 ff. 'Il.i.i, page 298. "Iljid., page 296. NORTH CAROLINA. 277 Davidson county. Other counties in which silver has been found and in some instances mined with inditfei-ent success are Burke, Caldwell, Wilkes, Gaston, Cabarrus, Union, Montgomery, McDowell, Madison, Johnston, Cherokee, and Surry.' From the earliest da3's of placer gold mining in 1799 on the tributaries of the Pedee down to the decade im- mediately preceding the Civil War, North C'arolina ranked as a mining state of the lirst importance. The bulk of the mining done in the state during this period was gold mining, and from 1804 to 1827 all the gold produced in the United States, amounting to $110,000, came from the mines of this state. ^ That part of the product of the gold mines of the state which was de- posited in the United States Mint and its branches be- tween 1804 and 1866 amounted to nearly $lO,0Oti,(.)0(.). After the working out of theiarincipal placer deposits, and when the progress in quartz mining had reached the point where, owing to the fineness of the gold and the increasingly refractorj^ character of the ores as the water level was reached, further profitable pi-osecution of mining with the crude machinery then in use had be- come a problem of doubtful solution, a decline took place in mining activity. This decline was greatly ac- centuated l\y the discovery in California in 181:8 of rich placer deposits and by the beginning in 18.51 of quartz mining in the same state, where high-grade, free-milling ores had been found in great abundance. Finalh', the advent of the Civil War and the discontinuance of the branches of the United States Mint at Charlotte, N. C, and Dahlonega, Ga., brought to a practical close this long and interesting period of mining activity' in the state's historj'. Since 1866 mining for gold has been carried on in tlie state in a somewhat desultory way, and in later years other minerals and other sections of the state have claimed attention. The mineral wealth of the state is bjr no means confined to the eastern slope of the Blue Ridge — the principal gold belt, \^^est of that range, between Smoky mountains and the Blue Ridge, and from the upper water of the French Broad river westward, there is a rich mining field. Mica. — Mica is found in a half dozen or more counties in the state, most of which lie west of the Blue Ridge. The most noted localities are in Mitchell and Yancey counties on the waters of the Nolichucky between the Black mountain and the Roan. In this basin are a great manjr enormous ledges of granite from which the marketable D:ica is obtained." Modern mica mining in the state dates from 1870, since which time North Carolina has produced a very important percentage of the total yield of this mineral ' The Minerals and Mineral Localities of North Carolina, page 12, and (jeology of North Carolina, Vol. I, page 2S8 ff. ^United States Geological Survey, Sixteenth Annual Kejiort, Part III, page 256, "Geology of North Carolina, Vol. I, jiage 299. in the United States. In 187<» the (mtirc reported product of the t^ountry was from this state. In 1S80 it was 18.3 per cent; in 1890, 13. .3 per cent; and in 1902, 59.9 per cent of the totah There is one point of unusual interest connected with the history of mica mining in this state. The industry is not really a new one, but has only been revived. The present woi'kings are continually cutting into ancient shafts and tunnels, and hundreds of spurs and ridges of the mountains, especially all over Mitchell county, are found to be honeycombed with extensive ancient work- ings of which no one knows the date or history. In one locality open pits 40 to 50 feet wide bj^ 75 to 100 feet long, filled up to 15 or 20 feet of depth, are disposed along the sloping crest of a long terminal ridge or spur of a neighboring mountain. The excavated earth is piled in imge heaps about the margins of the pits and the whole overgrown with the heaviest forest trees — oak and chestnut — some of them 3 feet and more in diameter, and some of the largest, belonging to a former generation of forest growth, falleit and decayed.'* It would thus appear that not less than three hundred years have passed since these pioneer toilers wrote in the unmistakable language of pits and tunnels the first chapter of the history' of mining in the state. These old workings were at one tiiue thought to be abandoned Spanish silver mines. There is no appearance, how- ever, of a silver \'ein and no explanation of the object of these extensive works othei' than that they were for the purpose of obtaining the large plates of mica or crystals of cyanite, both of which abound in the coarse granite rock. It is known that mica was of conmion occurrence in the tumuli of the Mound Builders, among the utensils and ornaments which such primiti\'e people were in the habit of burying with their dead. Many cut forms similar to those found in the mounds have been discovered among the rubbish and refuse heaps about and in these old pits. These facts reveal, there- fore, the purpose and probable date of these ancient workings and show them to have been contemporary with the extensive copper mining operations of Lake Superior.* 2[oiiazl.te. — The total product of monazite mining in the United States reported in 1902 came from the state of North Carolina. While the existence of monazite in commercial quantities in this state was first estab- lished in 1879, by Mr. W. E. Hidden, of New York, who, in the interest of Thomas A. Edison, the in^•entor, inspected the gold placers on a hunt for platimmi, the first recorded product of monazite mining in the state was in 1887, and came from the Brindleton district, in Burke county."' //■'/// iiff. — Th(^ first recoriled discovery of iron ore in North America occurred in the vear 1585, in North *<:eology of North CaroUna, Vol. I, page HOI.

It was made hy an expedition fitted out ]>\ Sir ^^' alter Raleigh, and coniinaiided by Ralph Lane, and which attempted to plant an English colony on Roanoke Island. The ore was found near the coast, and althouuli the importance of the discoA-ery was fully realized, no attempt was made to utilize it, as tlie col- onists were then on a search for gold. It was many years after that a permanent settlement was made, and the industry of iron mining and manufacture was well under way in many other colonies before its be- ginning here. ^ Iron ores of high grade and in large quantities have been found in many sections of the state, and at ditlerent periods during the last hvmdred and twenty -five years the production of iron in the state was an industry of relatively marked importance. The ranges of iron ore deposits are widely distributed, but in the main fall within the following counties: Chatham, Orange, Guilford, Gaston, Lincoln, Catawba, Yadkin, Surry, Stokes, jNIitchell, Ashe, Madison, Cher- okee, and Johnston.'' The product of the state is still small. That reported for 1902 came from Jolmston, Madison, and Mitchell counties. Barytes. — The commercial production of liarytes in North Carolina, first noted at the census of 1.S81>, is confined chiefly to Madison county, though deposits have also been found in Gaston, Orange. Cabarrus, and Union counties. ' For the j'ear l;_t02 the production of barytes was $4-t,130, or 21.7 per cent of the total product of the United States. All other miiieraU. — Deposits of liituminous coal exist in the state in Stokes and Rockingham counties, in the valley of the Deep river. Coal has also been found in Chatham and Moore counties.' No statistics can be shown without disclosing individual operations. Copper ore is found in many places in the state, the principal variety being chalcopyrite, or copper pyrites. Before the Civil War the industry of copper mining- had made considerable headway-. Many of the gold veins are associated with pyritic ores, practicallj' all the old copper mines of the central part of the state having been worked first for gold. The general char- acter of these mines was that at about water level the so-called "brown gold ores" were replaced by f[uartz richly cliarged with iron pyrites more or less mixed with copper pyrites, the latter increasing as the mine deepens, and in many places beconiing the only or the pi-edominating ores, and forming a regular copper vein. Perhaps the most valuable deposits of copper in the ' Iron in All Ages, by .James M. Swank, page 111-' ff. ''■ Oeolojiy of North Carolina, Vol. I, page 218 ff. ■'The Minerals and Mineral Localities of North Carolina, page 8.3. ■•United States Geological Survey, Sixteenth Annual ReiJort, Part IV, page 153. state are in Ashe, Alleghany, and Watauga counties; the most remarkable vein in this range is at Ore Knob, in the southeast corner of Ashe county, near the top of the Blue Ridge.' Abrasi\'e garnet is widelj' distributed through the state, and is a regular con.stituent of many of the mica and hornblende slates. Large crystals of a brownish red color are frequently met with in the mica mines of Mitchell and Yancey counties. The product of the North Carolina garnet mines has obtained the highest price in the market, 160 per ton. The total product of the state for 1902 was from Jackson countv. Graphite occui's in many localities in the state. The largest beds are in Wake count}'. Others occur in Lincoln, Cleveland, Catawba, Alexander, Stokes, Wilkes, Person, and Yancey counties." Limestones though not abundant are found in more than twenty counties, and distributed throughout the state. Those in the eastern part are a shell conglomer- ate, valualjle l)oth for building purposes and for the manufacture of lime. Those of the middle and western section are frecptently crystalline, and in several comi- ties, especially in Cherokee and Macon, constitute a very good marble. Precious stones have been picked up at many places in the central and western part of the state. Among these have been a half dozen or more diamonds. The first one was found in 1813 by Dr. M. F. Stephenson, of Gaines- ville, Ga., at the ford of Briiulleton creek, in Burke county, and was worth about $1()(!).' Garnet crystals of great beauty and perfection and of various colors are fouTid in Burke. Caldwell, and Cata«l)a counties.' A peculiar green garnet has l>een foiuid in the Co\-ee valley, for which the name rhodolite has been generally adopted. Many emerald matrix specimens have been found at Crab Tree nujuntain in Mitchell county. Mining for amethyst has met with considerable success at Tesnaty, on the creek of that name, in Smith Bridge township, Mitchell county, where a large vein occurs in an altered pegmatite. Crystals are found from one- half to 8 inches in length, and in color they are light and dark, the dark spots often being of the deepest, richest purple. No finer amethysts have been found in the United States. Several thousand dollars worth of stones were sold from the first development work. A very interesting new form of moonstone has been found near Bakersville.

This area i.s a part of the NORTH DAKOTA. 281 so-called Rocky mountain coal Held, which also includes the coal areas of Montana, Wyoming, Utah, Colorado, New Mexico, Idaho, and Nevada.' The earliest pro- duction of coal worthy of statistical notice was produced in 1884.' The North Dakota variety does not stand, transportation well, and consequently can nt)t com- pete with bituminous coal, except when the latter is high priced. To be sold at a profit, therefore, North Dakota coal must at present find a comparatively local market.' In 1902 the mines of the 47 operators reporting were located in Burleigh, McLean, Morton, Stark, and Ward counties. The total output was 226,511 short tons. Ward county produced 93,786 tons of this amount.

The petroleum and natural-gas output is very large, a number of the most productive wells in the country being found in this .state. Some of Ohio's building stones are among the finest in the United States, and find a read}' market. Practically the entire output of grindstones and all the pulpstones produced in this country come from this .state. To supply its extensi\-e iron and steel industries Ohio depends on other states for the necessary iriiu ore, as its own deposits are not rich either in (juantity or quality. Ohio is one of the leading states in the manu- facture of Portland cement, and has long been a pro- ducer of natural rock cement. Sandstone al>ounds and when crushed and screened is used in glassmaking and for other purposes. Large and valuable deposits of clay aid in giving the state its leading position in the cla\' working industries. hi addition to the minerals referred to in Tafile 1, .strontium ore is found at Put in P)ay, Ottawa county, but none has been produced in commercial ([uantities since 18'.*T. The operators reporting acti\-e mines and wells, but no production, gave employment to 2i)4 wage-earners and paid $122,722 in wages during ll»02. The co.st of supplies and materials amounted tt) §27,iU2, and of con- tract work to $14,171. The relative importance of manufacturing industries closel}' allied to or based upon tlie mining industry, using as their raw material the product of the mine or quarry, is shown in the following table: Table li. -M(niul'actart'.'< b'A.'2 was less than that for 1901, the product sold at an increase in price averaging 1 cents per barrel. ■'Tenth Census, Vol. X, page 12. * Uniteil States Geological Survey, ].iage 9(1. ■Petroleum Bulletin," 1902, 284 MINES AND QUARRIES.

They are almost uniformly of a dull color, and though in manj- cases durable and strong, are entirel}' unfit for any sort of fine building or ornamental work. They are, there- fore, used chiefly for the rough work of foundations, street paving, and flagging, and to a ver_v large extent for making quicklime.' Ohio in 1902 ranked third in value of product in the list of limestone producing states, being exceeded b\' Pennsylvania and Illinois. Natural gas. — There are three natui'al gas fields in Ohio. The first known field was along the eastern mar- gin of the state, where occur the sands of the Lower Coal Measures, the Waverh' Series, and the Ohio shales. The second field, the la.st to be developed, is in the central portion of the state and receives its natural gas from the Clinton limestone of the Upper .Silurian series. The third field is found in the northwestern portion of the ,state and obtains its natural gas exclusively from the upper portion of the Trenton limestone of the Lower Silurian series. Natural gas was first used in Ohio in 1866 in the manufacture of lampblack at Gambler, Coshocton county; in 187i it was used at East Liver- pool, in the household, for heat and light. The great Trenton rock gas field was first opened at Findlay in Movember, 1884, and the Lancaster gas field was de- veloped by a well drilled near that city in 1887.^ The gas produced from the eastern portion of the state was not developed in suHicient (juantities to warrant the piping of it to far distant localities, but it has been an important factor in supplying many nearby towns and industries. ■Stones for BuildinK tind Decoration, by George P. Merrill, page 319. MInited States Geological Survey, "Mineral Ke.soiirccH of the United States," 1902, j.age 645. The value of the natural gas produced in Ohio in 1902 was $2,3.55,-458, which is an increase of $208,243 over 1901. The greatest production was in 1889, after the great Findlav gas field had been first opened; the small- est production was in 1897, just before the Lancaster and Sugar Grove pools were developed. Of the 1,353 wells in operation during 1902, the 637 wells located in the counties of Fairfield, Franklin, Hancock, Licking, Knox, Belmont, Guernsey, Noble, and Mercer produced natural gas valued at $2,107,731. The remaining 715 wells M'ere located in the following counties: Allen, Ashtabula, Auglaize, Columbiana, Cuyahoga, Darke, Hardin, Harrison, Holmes, Lake, Logan, Lorain, Lu- cas, Monroe, Morgan, Ottawa, Sandusky, Stark, Van Wert, Washington, and Wood. Sandstones and qvartzites. — Quarries of excellent sandstone abound in Ohio, of which the so-called Waverl}' group are the most important for building- purposes.^ The greatest sandstone deposits, known geologically as the Berea grit, are located in Cuyahoga and Lorain counties. The stone, of a veiy light bufi', graj% or blue-gray color, is famous for its evenness of color and puritj' of texture, and for building purposes finds a ready market throughout the United States. The value of the sandstone quarried in these two counties in 1902 for building purposes amounted to $828,284. The value of the sandstones and quartzites production of Ohio for 1902, $2,078,754, is exceeded only by that of Pennsylvania. These figures do not include the value of stone quarried for grindstones and pulpstones. The 115 quarries operated during 1902 were located in the following counties, arranged according to the value of the production: Cuj-ahoga, Lorain, Scioto, Fairfield, Summit, Erie, Richland, ^lorrow, Belmont, Carroll, Huron, Muskingum. ^Mahoning, Trumbull, Crawford, Holmes, Harrison, Jefl'erson, Stark, ^Morgan, Tuscara- was, Washington, ^leigs, Pike, Columbiana, Ashtabula, Guernsey, Licking, Delaware, Miami, Pickaway, High- land, and Perry. .Cement. — Among the first cement plants to be estab- lished was a small one at Sandusky, about 1845. In 1846 a plant was established at Defiance, and in 1858 at Barnesville. The first Portland cement plant was estab- lished in 1889.* In 1902 Ohio ranked seventh among the states manufacturing this material. While the growth of this industry in Ohio has been steadj', it has not been as ma'rked as in some other states. In 189() the prf)duction amounted to only 57,0(i<» barrels while ill 1902 it amounted to 563,113 barrels. But one com- pany now produces natui'al rock cement. Grindsf ones and pidpstimes. — Four-fifths of all the grindstones produced in the United States are quarried in Ohio, the sandstone known as the Berea grit l)eing the greatest source of supply. The 7 quarries operating ' Stimes for Building and Decoration, page 1.54.

The value of the total output in Ohio was $.560,413, while that of the United States was $(167,131. The following table shows the value of the aTinual production of grindstones, 1S1(9 to 11103, it being im- possible to segregate the production from the total for the United States previous to 1899: Tablk C. — Viiliii' of (iiiiiiiiil prnihirtiiiii iif iiriiiihtdiu'x: IXifi In lUOJ.

The single gypsum plant in the state is near Gvpsum, in Ottawa county. The product is converted princi- pally into wall plaster. The first blast furnace in Ohio was completed in ISUI, in Mahoning county,' and it is proljable that iron ore was first mined in this state about that time. The Hanging Rock district, in Lawrence county, along the Ohio river, was once (juite a source of supply, but during late years the quantit}" of iron ore mined in Ohio has steadily de- creased, owing probably to the inferiority of tlie ore. In 18S9 the production of iron ore in Ohio amounted to 2.54,394 long tons, while in 11»0'2 it was only 22,657 long tons. The silica sand production for 1903 was valued at $153,374. A little less than a quarter of this crushed sandstone is used in the manufacture of glass. At a nunilx'r of the quarries in the Berea sandstone district a grade of stone is found suitable for making whetstones. The well-known Deerlick oilstone is made at Chagrin Falls, Cuyahoga county. The value of the production of whetstones and oilstones in Ohio can not be shown separatelj" without disclosing the operations of an individual establishment. The pvrite produced tij' three operators in Tuscara- was county is a by-product of coal. The phosphate rock produced is found in Mahoning county. ' Iron ill All Age>^, l>y Jame.s M.

From the al)o\e table it appears that mining- in Okhihoma during 1902 was contined to the quarry- ing of limestone, gypsum, sandstone, and the opera- tion of three petroleum wells, (iypsum is by far the most important product of mineral industr_v in the territory. Many stories have been circulated from time to time regarding old Spanisli mines existing in Oklahoma,' )mi they have little foundation. It is claimed, however, that dates cut in the rocks in the Wichita mountains'' indicate the discoverv of gold as early as 1S3M. These mountains are located in tlie forbidden ground of the Kiowa and Comanche reservation in the southwestern part of the territory, and prospectors or minei's are not allowed to explore the locality. There are indications in many parts of the territory of the occurrence of coal, asphalt, zinc, lead, copper, iron, coljalt, mica, clay, and cement,^ but no production of these minerals was reported in 1902. Coal has been obtained in small quantities in Pawnee coiuity and in tlie Osage reservation, and is also known to occur in Payne, Lincoln, Logan, and Pottawatomie counties and in the Kiowa and Comanche reservati(jn. Deposits of co[)per occur near Kentfin in the extreme western end of Jiea\'er county; zinc and lead are found ' Itejxjrt among the minei'als reported liy Lewis and Cliirke in their ex- ploration into this territory in IsOo to 1807.

In the Blue mountain region and the Kogue river section of the state are the principal gold producing localities. Although silver bearing ore is quite widel}' diffused, the production reported was principalh' ob- tained in the form of allov with gold. The presence of more or less important coal deposits is indicated by outcroppings throughout the western and north- western parts of the state and in Coos count}-. The deposits of stone promise unlimited supplies of building- material. ' Gypsum, used in making land plaster, occurs in Baker country; borax is found in Harney countjr; deposits of copper are known to exist in many portions of the state; and nickel ore occurs in Douglas county. In addition to the production reported, valuable min- eral deposits occur in many portions of the state. Some of these regions have been prcspected or operated to a considerable extent, while others await only the advent of transportation facilities or the expenditure of suffi- cient capital in development to make them valuable workings. A sj'nopsis of the principal of these known occurrences is herewith given, compiled chiefly from the facts gix'en in the third revised edition of "The Re- sources of the State of Oregon," as collected and ])re- pared by the state board of agriculture. Antimony occurs in Jackson county, and tisbcstos of good fiber is found in the southei'n and eastern part of the state. Alkaline salts, potash, sodium, and niter, and also borax, for which a production is reported in 11»02, are obtainable from lakes and spi-ings in the arid region, east of theCascadcis, Natural comentis reported in Douglas countj' and chi'ome ii-on oi-e or chromite in a condition of remarkiibic piii'ity and in almost exhaust- 'T?ie Kesrmrces of Oregon, [lage.s 29 to 42.

Clay is found in Clackamas, Clatsop, and Coos counties; glass .sand exists in streams flowing from granite rocks; and graphite and infusorial earth are obtained in Jackson count}'. Important deposits of iron ores exist, chiefly in basalt, in twelve counties, for the most part in the western half of the state, although occurrences are also noted in Umatilla and Grant counties in the Blue mountains. Lead is found in Clackamas, Grant, and Linn counties, principally as galena. Magne.site and other refractoiy minerals are obtainable, at least in small quantities, in the serpentine rocks of southern Oregon. Manganese ore occurs in Columbia county, in the northern part of the state; marl)le is found in Josephine and Wallowa counties, and platinum and iridium in lodes are believed to exist in the south, principally in .Coos, Curry, and Douglas counties. Of the precious stones, jet has been found in Clatsop county, while opals, serpentine, and chrysoprase, generally useful for ornamental purposes and occasionally rising to the dignity of gems, have all been reported in the state. Quicksilver has been noted in Douglas and Jackson counties, and zinc is known to exist in the Cascade range in Lane and Linn counties, chiefly in the form of zinc blende. Nonproductive development operations were carried on ([uite extensively in 1902, 192 operators reporting expenditures as follows: Salaries, iil62,18-l; wao-es $805,855; contract work, 175,594; cost of supplies and materials, $21:1 ,161 ; and miscellaneous expenses, $47, 191. These operations are reported for gold and silver, quick- silver, and coal (bituminous), named in the order of the amount expended.

The product of mining and quarrying in 1902 was $2,087,389, or 4.3 per cent of the combined value of the product of manufactures in 1900 and of mines and quar- ries in 1902. Manufactures in 1900 gave employment to 17,236 wage-earners, who received $8,333,533 in wages. Mines and cjuarries in 1902 gave emploj-ment to 1,166 wage-earners and paid $1,033,075 in wages. Of the combined figures for the two industries — 18,1(12 wage- earners and |i9,366,608 paid in wages — manufactures gave employnient to 93.7 per cent of tlie wage-earners and paid 89 per cent of the wages, while mines iind quarries employed but 6.3 per cent of the wage-earners and paid 11 per cent of the wages.

Gold and .nlver. — Gold was discovered on the Co- quillo river in 1852 and along other streams in south- ern and eastern Oregon.' The Blue mountain region is the principal gold producing place, with the Kogue river section second in importance. Placer mining is more productive in the western, and quartz in the east- ern part of the state. The first quartz mining was re- ported in 1860. Silver bearing ore is quite widel}' diffused, but the percentage of the precious metal is often disappointing. The silver reported is principally obtained in the form of alloji- with gold, but important discoveries in lodes have been prospected and promise well.

The coal produced is mainly lignite, with an average of le.ss than 50 per cent fixed carbon, a consider- able proportion of water, and from 5 to 20 per cent of ash. Oregon coal is free burning and well adapted for steam and heating purposes, although it will not coke. The following table shows the annual production from 1885 to 1902: Table .5. — Annual production of coal, liitunrinous: 1SS,5 to 190S.

The annual product has varied considerably, the year of least production being 1892. The greatest produc- tion was reported in 1897; since that time a decreased product has been shown. In 1902 development opera- tions were reported which indicated an increasing- interest. Siliceous crt/«talli/ie rocJcti. — Rocks of volcanic origin predominate in the state; among them are the andesites, the true basalts, the trachytes, and the tufas or frag- mentary rocks. In 1902 the entire production was re- ported from Baker, Benton, Gilliam, Jackson, Marion, Multnomah, and Union counties. It was valued at 138,429. The production during 1902 showed a decided in- crease as compared with the years following 1890. This increase in 1902 is chiefly attributed to the more extensive use of the stone as a 2:)aving material and in roadmaking. Limestones (ind dolonntes. — Limestone deposits at present commercially worked occur in Baker and Wal- lowa counties in the northeastern, and Jackson and Josephine counties in the southwestern part of the state. In Grant and Union counties there are valuable deposits,' the latter county being covered to a large extent with blue limestone. During 1902 the entire production, valued at $20,133, was used in lime liurning; in 1901 a value of $12,420 was reported for lime burning; in 1900, $10,525; and in 1899, $8,000. There was thus a steady increase in the use of limestone for this purpose. The comparativel}' large product shown for 1901 included a value of $12,100 quarried for paving and roadmaking, while during 1902 siliceous crystalline rocks were more ' The Resources of Oregon, pages 29 to 42. extensively used as a paving material and no limestone was reported except for lime burning. All other minerals. — The entire production of borax in 1902 was reported by one company in Harney county, although borax and various other alkaline soluble salts are found also in Klamath and Lake counties. The arid plains of this region are of late volcanic origin and contain lakes with no outlets, carrying useful salts in heavy solution. All the production reported was submitted to a process of crystallization before being marketed. The copper produced is chiefl}' copper-glance and nati\'e copper, carrying gold, and it occurs chiefly in Assure veins. Deposits are known to exist in many parts of the state, notably the native ore and chalcopy- riteof theSantiam region in Liim county, the sulphides of the eastern Oregon gold quartz mines, and the native copper of Union and Baker counties. "* The 1902 pro- duction was reported by one company in Josephine county in southern Oregon, and was all reduced by smelting. A considerable production of gypsum was reported in Baker county, none of which was sold in crude state, all l)eing prepared as land plaster, wall or cement plas- ter, or plaster of Paris. As onl v one company was en- gaged in this production the statistics can not be given separately, because to do so would disclose the opera- tions of an individual establishment. Nickel ore occurs, in association with garnierite, chromite, magnetite, chrysoprase, chalcedonic cpiartz, and serpentine minerals, principally in Douglas county.^ A small production was reported for 1902.

The value of the output of the productive mineral properties of the state in 1902 was $236,871,417, or 29.7 per cent of the total value for the United States. The most important of the .state's mineral resources, from a commercial standpoint at least, are its coals. In its vast stores of anthracite coal, which underlie some 484 square miles,' Pennsylvania has a notable advantage over other states. There are three groups of parallel valleys in which these coal measures appear, the North- ern, or Wyoming and Lackawanna valley, the Middle, or Lehigh and Mahanoy, and the Southern, froui which the Lj'kens valley coal comes.'' The bituminous coal fields which run in six parallel valleys' from New York to Ohio and West Virginia, underlie some 15,800 square miles of the state, and belong to the great Appalachian field, which also includes the coal regions of Ohio, 'United States Geological Survey, "Mineral Re.sources of the United State.s," 1902, page 291. 'The Anthracite Coal Industry, by Peter Roberts, pages 5 and 6. 'King's Handbook of the United States, page 722. Maryland, Virginia, West Virginia, eastern Kentucky, Tennessee, Georgia, and Alabama.' The petroleum and natural-gas fields cover many square miles of the state's area, and in the combined values of petroleum and natural-gas production Penn- sylvania leads among the states. The Cornwall hills, in Lebanon count}', are composed of and underlaid with magnetic iron ore forming one of the most wonderful deposits of this variety of ore in the world. Since 1740 nearly 9,000,000 tons of ore have been quarried from these beds. Fine brown hema- tite is taken from great open quarry mines in the cen- tral valleys and transported hy rail to the iron works in the bituminous coal region beyond the Alleghenies and along the Lehigh and Schuylkill valleys." At Friedensville, in Lehigh county, are located the zinc mines which were opened in 1853, and were strong producers up to 1876."

The quarries at Slatington, in Lehigh county, produce vast quanti- ties of the finest l>lue-l)lack slate for liilliard tables and mantels, blacklioai'ds and slates, flooring and rooting.' The Gap mine, in Lancaster county, once tlie most im- portant nickel mine in the country, was opened in 1718 and worked for copper until 18.VJ. wIkmi tlic presence of nickel was discovered." The mine is now shut down. Marble of many varieties, from ))lack to white, is found in the Great Valley, in Chester county, and has been (piarried in immense (luantities in ]\Iontgoin(>ry count3-. Serpentine, or greenstone, largelv used in fine buildings, is quarried at Birmingham, and else- where in Chester and Delaware counties.'' Among other minerals in deposits of which the state is rich may l>e mentioned the following: The mineral paint, of Parry ville: steatite or talc, of Schuylkill; fire clay and flagstones in several localities: the bluestone, of Tunkhannock and Meshoppen; chrome ore and graphite, of Chester county: sih'cr bearing lead, form- erly mined in large quantities in Chester county; sand- stones, of Swatara and Schuylkill counties; whetstones, of Darby creek; granites, of Delaware and Philadelphia counties; and the kaolin, of Pennsburg and New Gar- den, used for making porcelain and china.' The minerals found in the state, but which were not produced in commercial quantities in 19()2,are chromite, gypsum, ilmenite, lead ore, manganese ore, nickel, plati- num, rutile, strontium oi'c, and zinc. In addition to the productive nunes, quarries, and wells referred to in Table 1. there were 18 operators in 1902 who reported development work, mostly in con- nection with l)ituminouscoal, natural gas, and slate prop- erties. These operators paid their salaried officials, clerks, etc., $3,59() during the year, gave employment to an average of 44 wage-earners, and paid S2().75i! in wages.

The Upper Carboniferous in the bituminous coal fields of Pennsylvania has been divided into the following five subdivisions in descending order: Dunkard, Mononga- hela, Conemaugh, Allegheny, and Pottsville. The prin- cipal sources of coal are the Allegheny and Mononga- hela formations, over 95 per cent of the output having been derived therefrom. Shipping mines are also lo- cated in the Pottsville and Conemaugh formations, the mines of the former being situated on the very extensive outcrop near the margins of the coal fields, while those of the latter are almost entirel}^ confined to the area of this formation near the southern boundar}' of the state. '^ The earliest recorded instance of the mining of bitu- minous coal in Pennsylvania was in 1760, when a, coal mine was opened in the deposit along the Monongahela river, at a point opposite the site of the present city of Pittsburg. With the advent of the first steam engine in Pittsburg in 1794 the demand for this fuel increased, and by 1800 a number of mines wei'c being worked on both sides of the river, the coal being used quite exten- sively in salt works, glass factories, and for general purposes. ' Coal was first shipped from Pittsburg in 1803, and in 1S16 the shipments from this point down the Ohio river amounted to 214,000 tons. About 1843 commercial shipments from the Blossburg basin began, and a little later the Barclay basin was developed. During the same decade the use of the Sharon Ijlock coal in the Mercer county furnaces is said to have begun. The rapid development of the Cambria county coals prac- ticall}^ began with the construction of the State Portage and Pennsylvania railroads, and shortly after the com- pletion of the Low Grade division of the Allegheny Valley Railway in 1872 the notable development of the Reynoldsville basin began.' In 1902 there were 1,023 productive ))ituminous coal mines in Pennsylvania, and the total output was 98,574,3(37 short tons, or 37.9 per cent of the produc- tion of bituminous coal in the United States. The value of this bituminous coal product was $10(1,032,460, or 44.8 per cent of the total value of all mineral prod- ucts of the state and 13.3 per cent of the total for the United States in 1902. Twenty-four counties in the state contributed to the production of this mineral. Among these, Fayette and Westmoreland, which contain the Conncllsville coking region and which have stood for a number of years at Ulnited States Geological Survey, "Mineral Re.iources of the United States," 1902, page 293. 2 Ibid., Twenty-second Annual Report, 1900-1901, Part III, page 127. nbid., pages 129 and 188. * Ibid., page 188. the head of the bituminous coal producing counties, retained their supremacy, the former having a produc- tion of 18,988,(J58 tons, and the latter 18,811,511 tons. Allegheny county is third in rank, with 11,919,569 tons, and Cambria county, with 10,561,835 tons, ranked fourth.''

The area is divided geographically into four divi- sions, known as the Northern, Eastern Middle, Western Middle, and Southern, and there is also a small basin in Sullivan county, known as the Western Northern or Loyalsock.' Of these fields, the Northern, also called the "Wyoming, contains 200 square miles, or 34 per cent of all the workable coal area.

The extreme northern point of the crescent is in Sus- quehanna county, near Forest City, and the remaiiuk'r of the region is in Lackawanna and Luzerne counties.' Since 1S66 this region has been the leading shipper of coal." The Middle fields contain 130 square miles and their total length is 40 miles. These deposits lie principally in Luzerne county, but some sections are in North- umberland, Carbon, Schuylkill, and Columbia counties.' The Southern field extends over 1-ftt square miles and lies in Car))on, Schuylkill, and Dauphin counties. The greatest width is about 4 miles, at Pottsville, and tlie length is 55 miles.' The first authentic record connected with anthracite coal history' in the state is that in ITO'2 coal was dis- covered by the early pioneers in the Wyoming district, near the site of the present city of ^^'ilkesl)arre, and in 1769 it was first used by Obadiah Gore, a blacksmith. The presence of coal in the Schuylkill region was known . in 1770, but the beds were not developed until is'di. From 1775 throughout the Revolutionary A\'ar anthra- cite coal, from the mines near Wilkesbarrc, was shipped to the arsenal at Carlisle for use in the manufacture of war materials.' Anthracite coal was first discovered in the Lehigh region, near Mauch Chunk, in 1791 and in the follow- ing year the Lehigh Coal Mine Company was formed and secured control of a large tract of coal land. It was not until 1802, however, that this company suc- ceeded in floating coal laden arks duwn the .Susque- hanna and through the Lehigh and Delawai'C livers to Philadelphia. Owing to the belief that the coal would not burn, no progress was made in the development <>i the coal trade for some years.' In 1805-6 two brothers, by the name of Smith, set- tled in Plymouth, Pa., bought coal lands, and at once commenced shipping coal to points along the Susque- hanna river, and although reports of the anthracite coal trade usually conuuenci.' with 18i^0, when 365 tons of coal were shipped to Philadelphia from the Lehigh region, the real credit should be gi\cii to the Smith brothers, who had been shipping coal successfully for thirteen years prior to the date usually accepted as that beginning the record. The trade from the Lehigh region was firmly estab- lished between IS^lu and 1823. About 1825 the Scluiyl- kill region was opened and in LS29 coal was being shipped from Carlxnidale." Fi'om this time on th(^ trade has rapidl}' inci'eased until it has reached its present enor- mous proportions. 'The Anthracite Coal Industry, page 5.

During the early days of anthracite coal mining a large percentage of the contents of the veins was not turned to commercial use. The methods of mining, transporting, and pieparing were wasteful, and the operators were not economical in exploiting the veins, thinking them inexhaustible. In these early years of mining there was nothing to enforce economy in pro- duction, as the veins were rich, labor cheap, and prices comparatively high. These conditions existed until some years after the Civil War. when, owing to the diminution in profits, a more careful study was made I of economical mining. Supplies were more carefullj' handled, the veins were operated more scientifically, and attention was gi\en the great waste annually going on in the amoiuit of coal sent to the dumps. Early in the fifties mining engineers in England had called attention to waste in mining, but it was not until many years later that nuiiing engineers in this country turned their attention to the great waste in the anthracite coal fields. As a result of modern methods more coal is now })eing mined from the seams, better devices have been intrf)- duced in haiuUing it, and better machinery put into the breaker. A great economy in the use of coal was effected with ■ a decrease in its size. Between l87<.i and 1895 four or five sizes, theretofore unknown to the trade, were prepared for the market, and to-day they comprise 30 per cent of the coal shipped. I In 1890 attention was directed to the old culm heaps, I so long such a disfiguring element in the coal regions. Previous to 1870 all sizes below cliestnut were sent to the culm dump, and it has beer, estimated that in that j'car these dumps contained about 76,000,000 tons of marketable coal, and in the decade, 1870 to 1880, it has been estimated that about 19,500,000 more tons were thrown away. The matter of reclaiming the culm ; dumps was agitated. D(\spite opposition from many sources washcries were erected, and by the introduc- tion of machinery, whereby still smaller sizes of coals could be prepared, a large percentage of the waste is now reclaimed and mark(»ted.'' The production of the 35 washcries rejiorted iit the census of 19o2 amounted to 2.977,:'i55 long' tons. In 1902 the 334: productive anthracite coal mines pro- duced 36,9-10,710 long tons, the smallest annual pro- duction since 188<), while in 1901 the production was 60.2-12,560 tons. This decrease-of 3S.T per cent was entirely caused by the strike in the anthracite regions, which lasted from May 12 to Octolier 23, 1902.' The following counties contributed to the state's output of anthracite coal for 1902: Carbon. Colum- bia. Dauphin. Lackawanna. Luzerne, Northumber- land, Schuylkill, Sullivan, and Susquehanna.

The production to the close of 1901, as previously stated, amounted to 1,350,000,000 long. tons, which would indicate that there remained still available a total of 18,150,000,000 tons. Unfortunately, however, for every ton of coal mined and marketed 11 tons, approximately, are either wasted or left in the ground as pillars for the protection of the workings, so that the actual yield of the beds is only about 40 per cent of the contents. Upon this basis the exhaustion to date ha.o amounted to 3,375,000,000 tons. Deducting this from the original deposits, the amount of anthracite remaining in the ground at the close of 1901 is found to be, approximately, 16,125,000,000tons. Ifpon the basis of 40 per cent recovery this would yield 6,450,000,000 long tons. The total production in 1901 was 60,242,560 long tons. If this rate of production were to continue steadily the fields would become exhausted in just about one hundred years. Mr. William (Griffith, in a series of articles contributed to the Bond Record in 1896, considers that the estimates upon which the foregoing computations have been made were too liberal. His estimates of the amount of minable coal remaining at the close of 1895 was 5,073,786,750 tons.' 'Mr. Griffith's estimate includes all workable coal in the North- ern field having beds 4 feet thick and yielding 3 feet of clean coal. In the other fields it includes seams 3 feet in thickness, capal)le of yielding 2J- feet of clean coal. It excludes the culm piles, mine pillars, etc. The acreage of each bed is multiplied by the thick- ness of the seams in feet and thus reduced to foot-acres. Each foot- acre was estimated to produce 650 tons of coal, and on the 1st of January, 1896, the unworked areas were estimated to contain 7,805,826 loot-acres, or 5,073,786,750 tons. in the six years from 1896 to 1901, inclusive, the jiroduction has l)een, approximately, 308,570,000 tons, which would leave still available for mining 4,765,216,750 tons. This supply, at the rate of production in 1901, would la.st a little less than eighty years. But as indicating how susceptible to error are human predictions, it is well to state that in his carefully prepared statement, published in 1896, Mr. Griffith assumes the limit of annual production would be reached in 1906, and would amount in that year to 60,000,000 tons. This amount of production was reached in 1901, in just half the time predicted by Mr. Griffith, and the production of .lanuary, 1903, as. recently reported, shows that the anthracite mines are capable of producing at a rate of 72,000,000 tons annually in their present state of development. It is not to be supposed, however, that the annual rate of anthracite production will continue practi- cally uniform until the mines are exhausted and then suddenly cease. Portions of the fields have already been worked out, others are rapidly approaching total exhaustion, while others at the present rate of production will, it is calculated, la.st from seven hundred to eight hundretl years. If we can assume the annual production will have reached its maximum limit at between 60,000,000 an.l 75,000,000 tons, and that the production will then fall off gradually as it increased, we may expect anthracite mining to continue for a period of from two hundred to two hundred and fifty years. This estimate is based upon the assumption that the available coal will remain at about 40 per cent of the reserves. How much this may be increased by better mining methods and the utiliza- tion of former waste material it is impossible to say. Already a large amount of fuel is being recovered from the old culm banks, and it seems safe to predict that the coal saved will, in the near future, equal 50 per cent of the contents of the fields worked. However we may make our estimates of future production, it is apparent that the maximum output has been almost if not quite reached. The proiluction henceforth will be from lower levels and thinner seams than those previously worked. This will neces- sitate greater expense in mining and, consequentl}-, higher prices for the fuel. With higher prices will necessarily follow more economy in consumption, greater restriction of the market, and the increased competition of other fuels. All conditions seem to combine for the conservation of the supply of anthracite coal. Pi'trnJenni,. — The Indians are known to have collected what was called "Seneca oil" from petroleum springs, and the indications are that at a much earlier period the Mound Builders not onl}- gathered the oil flowing from springs, but even dug wells in Pennsylvania and dipped up the petroleum.^ The earliest mention of petroleum in the state ap- pears to have been in 1721, and on a map published in 1755 the word "petroleum" appears near the mouth of what is at pre,sent known as Oil creek, on the Alle- gheny river. From this time mention of the Seneca oil, naphtha, or rock oil, as it was variously called, be- came moi-e frequent.'^ The real beginning of the petroleum industry dates from the discovery in 1858 of Drake's well, near Titus- ville, in Crawford county. The success of this well, which produced 25 barrels daily, at that time an enor- mous quantity, occasioned a period of great excitement, and during 1859 and the next few years western Penn- sylvania was a scene of indescriliable activity and spec- -One Hundred Years of American Commerce, ^''ol.

Large number.s of wells were sunk along Oil creek, French creek, and the Allegheny river; arlven- turers iiocked thither from all parts of the country, and what shortly became known as the "oil region" was transformed from an almost unbroken forest into camps and towns. The first flowing well was struck early in 1861. Up to that tmie all of the oil was drawn from the wells by pumps. This well yielded 300 barrels per day and flowed for tifteen months. Soon after the largest [low- ing well ever operated in America, thc^ rhillips, was struck, giving 3,000 ))arrcls per day. The discovery of these "gushers" stimulated prospecting and enor- mously increased the produc'tion, with a corresponding decline in prices. That the productive territorj^ need not necessarily underlie the valleys and the river bottoms was demon- strated in ISfii'. In the succeeding years wells were struck on the high plateaus of Clarion, Butler, Arm- strong, McKean, and Warren counties, the Clarion- Butler, or Southern, tield lieing discovered in isTO. In 187-1 the great Bradford field was discovered. This field includes McKean county. Pa., and Allegany and Cattaraugus counties, N. Y., and has been one of th<' greatest oil producing fields in the history of the petro- leum industry. The other Pennsj'lvania oil fields are known as the Middle, including Warren and Forest counties; the Lower, or Southern, including Venango, Clarion, But- ler, Beaver, and Lawrence counties; and the Washing- ton, or Southwestern, including Allegheny, Washing- ton, and Greene counties.' For many years, in fact up to 1885, the Pennsylvania field, which includes New York, was looked upon as the undisputed source of sujDply of petroleum for the world, - and up to 1903 this field had produced 638,101,l.">t; bar- rels, or 53.9 per cent of all the crude petroleum pro- duced in the United States since 1859. In 1S91 the maximum annual output in the peti'oleum production of the state was reached. Since 1891 Ohio has sui'passed Pennsylvania in the production of petro- leum, and in 1902 the state ranked fifth, ))eing out- ranked b}' Ohio, Texas, California, and ^\'(■st \'irginia.

The counties cut by this imaginary line and all to the west of it pro- duce more or less natural gas.* . The presence of natural gas in Pennsylvania was undoulitedly known early in the eighteenth century, but the first recorded use of it in this country was in 1824, wiien a supply from a well was used to illuminate the village inn at Fredonia, New York." Early in the history of oil wdl drilling, which Ijegan in iS.V.t, the gas whicli always escaped from oil wells was usedasa f ucl for firing the lioilers on the drilling engines; it was soon being piped to houses foi- use as light and fuel. In 1872 the first natural gas plant was Ijuilt, and a 2-inch line run from the Newton well to furnisli gas f(.)r domestic purposes in Titusville, Pa., about five and one-half miles distant. It was not, however, until 1871 that the great value of natural gas as a manufacturing fuel was demonstrated. After that date its use rapidly increased until by isiiu it was estimated that natural gas had annually displaced as a fuel h),m{)MO tons of coal.' Before the \iilue of natural gas as a fuel was fullj^, appreciated the extensive fields aljout Pittsburg had been discovered. The first well in this field was opened November 1, l87.s, liut no att(>mpt was made to us(^ the product of this well for four j-ears, and very little drill- ing was done in the field until 1881. About 1 s;9o till' teriltory south of Pittsburg began to be developed, although gas had already been dis- covered and used to a considerable extent in the vicin- ity of Washington, Washington county. In the i^arly days of the production of natural gas .the original "'rock" pressure of the wells was so great and the product i\e area so extensive that the supply was believed to be yiracticallv inexhaustible, and as a result it was wasteil in the most extravagant manner. However, between ls,s5 and bsiHi the earlier fields began to show unmistakable i'\idences of depletion.

The stones of Subcarboniferous formation have been but little quarried for purposes of construction, although at Franklin, in Venango county, a fine grained, evenly bedded buff stone, resembling to some extent the buff variet}' of the Berea grit, is quar- ried for sidewalks and buildings in the vicinity. Aside from the Triassic .stones those quarried from the Devonian formations are the most important. The stone from this formation, known as the Wyoming Val- lev stone, agrees verv closel}' in general appearance with much of the bluestone quarried in New York state.' The value of the output of sandstones and quartzites, including bluestones, quarried in Pennsylvania in 1902 amounted to 12,800,108, which gives to the state first rank in the production of this class of minerals. The 1902 production exceeded that for 1901 by $737,026. Iron on-. — The magnetite varietj' of iron ore, as well as the red and brown hematites and the carbonate, is found in various localities within the state in deposits of more or less richness. The brown hematites are appar- ently divided into two series, starting in the northern section of the state, and running southwest in nearly parallel lines. The magnetites occur between these two belts. The carbonate vaiiety of iron ore is found in the western portion of the state, and between the carbonate and the brown hematite belts are found the red hema- tites.* The celebrated Cornwall mines of magnetic ore, con- taining one of the largest and richest deposits of this va- riety of iron ore in the country, ai'e located in Lebanon county, 5 miles south of Lebanon and about midwav be- tween Reading, on the Schuylkill river, andHarrisburg, on the Susquehanna." The area of ore here exposed measures al)out 4,0(»0 feet in a direction nearly east and west, with a Ijreadth of from IdO to 80(t feet, and in- cludes three hills, separated by two valleys, running north and south. These mines have been among the most iH'oductive iron ore properties in the country, hav- ing produced up to 1889 over 1(»,()00.(.>0(I tons." The limestones of the Cumberland \-alley are very rich in limonite, or brown hematite ores, which form a large part of the charges of the many l>last furnaces situated on their outcrops. The mines from which these ores are obtained are really only pits or tjuarries, the ores being extracted by means of picks and shovels.' While the presence of iron ore in Pennsylvania was undoubtedly known at an early date, it is not prol)able that any deposits were developed to any considerable ex- tent until the latter part of the seventeenth or the early years of the eighteenth century. ^Stones for Buildinfi; and Decoration, ]>ages 1,59 to 162.

PENNSYLVANIA. 299 The first recorded instance of tiie manufacture of iron witiiin the state was in 1692, and the first success- ful ironworks were establislied in 1716, on Manatawny creek, in Berks county.' In the same year the develop- ment of the iron ore mines of the Schuylkill valley began." About 17^0, a furnace, located in the heart of one of the richest deposits of magnetic iron ore in the country, was erected on Ironstone creek, Colebrook- dale township, in Berks county." The celebrated deposits of magnetic iron ore of Cornwall hills are said to have been worked about 1735,° and in 1742 the Corn- wall furnace was built. The mine was described, a few 3'ears later, as being rich and abundant. During the War of the Revolution, Cornwall furnace cast cannon and shot and shell for the Continental Army, and it was still in operation as late as 11S82.* In 1902 there were 42 operators in Pennsylvania who reported 47 productive iron mines, having an output of 822,932 long tons, which gave to the state sixth rank in quantity of iron ore produced. In the output of the different \'arieties of iron ores the state ranks first in magnetite, M'ith a production of 616,645 tons; sixth in brown hematite, with li-;5,S46 tons; and twelfth in red hematite, with 20,441 tons." In 1902 the following counties contributed to the state's output: Berks, Bucks, Center, Cumberland, Huntingdon, Lancaster, Lebanon, Lehigh, Northamp- ton, Perry, Snj'der, Union, and York. Among these Lebanon county ranks first, with 594,177 tons, or 72.2 per cent of the state's production, drawn entirely, in 1902, from the celebrated Cornwall mine. Center county ranks second with a production of 64.3(82 tons, and Lehigh county third with 58,508 tons. Pennsylvania showed a decrease of 217,752 tons in the production of iron ore in 1902, as compared with 1901. The value of the state's production was $1,225,453, or an average value of i^l.4!i per ton.

Rhode Island ha.s held for many years a very promi- nent position among granite producing state.s on account of the superiority of its granite for monumental pur- po.ses, 23articularly the stone that is (juarried at Westerly and vicinity.' In previous years some coal which was classed as anthracite was mined in the eastern part of the state. This product is not in reality an anthracite coal, but is grapliitic, and. in the last few vears, has been included with the graphite jjroduction." It is of a structure Vjetween scaly and granular, and contains, in selected samples, as much as U'l per cent carbon.'' The following minerals also occur in the state, Init were not mined in commercial (juaiitities in 1!>02: Asbestos, galenite, garnet, iron ore, talc and soapstcjiie, whetstones, copper ])yrite, sandstone, manganese ore, agate, jasper, and molybdenum in Provitlence county, and serpentine in Providence and Newport counties.'

Beginning in 1890 with an output valued at |ltSl,21(), the production decreased steadily until 181*3; then increased in 18i>4 to $1,211,439, the maximum in the history of the state. The value of the output decreased again gradually until 1898, when the lowest value, *320,212, in the last thirteen vears was reached. Since 1S98 there has been again a gradual increase, the value in 1902 amounting to $731,623. This output was oljtained from 19 cjuar- ries, 9 of which were located in Washington county, 6 in Providence, 3 in Newport, and 1 in Kent. The quarries in Washington county produced the greater part of the monumental stone of the state, 8 of the 9 quarries in this county showing this class of granite as their principal product. The output of the remaining cpiarries of the state was used chiefly for building stone, but some was also used as paving, curbing, and crushed stone for roadmaking and concrete, and some was sold as riprap and rul)ble stone. The value of the stone used for monumental work in 1902 was $650,719, or 75 per cent of the total, and in 1901, 1291,805, or 58.2 per cent of the total value for that year. For the years 1898, 1899, and 1900 no sep- aration was made of rough stone, but the chief product was dressed stone for monumental work. The importance of the state as a producer of monu- mental stone from 1898 to 1902 is shown in Table 1.

In 1899 the value of the production was 8.6 per cent of the total for all states, Khode Island ranking fourth, being exceeded hy Vermont, Massachu- setts, and New Hampshire. In 1900, 1901, and 19U2 the state ranked third, producing for the three j'ears respectively 11.5, 10.7, and 13.8 per cent of the produc- tion of monumental stone in the United States.

The output has been combined with that of limestones and dolomites to avoid disclosing the operations of any single establishment. Only two limestone quarries reported production in 1902, both located at Limerock, in Providence county. Almost the entire product was consumed in lime manu- facture, though a small quantit}- was used for fluxing l^urposes. SOUTH CAROLINA.

The range of mineral industry is contined in the main to three or four diti'erent proihicts. Notahl(^ among these is phosphate rock, in the mining of which the state still takes high rank, though in finnier }-ears it furnished nearly all of tlic production in tin.' I'nitcil States. Granite of high grade is found in aliundancc, and the kaolin beds of Aiken county arc c.\tcnsi\-cly worked. Gold ore, while not distributed over a wide area, is successfully mined. Amongthe minerals of the' ■state which were not mined commercially in VM)'^ are the following: Asl)estos occurs near Glenn Springs and C'edar Springs in Spartanbui'g county, and in Pickens county.

PhospJiate riich. — The pho.sphate rock licit of the state is To miles long and 30 miles wide, extending from the mouth of the Broad river, near Port Roj'al, in the ^^outheast, to the headwaters of the Wandti river in the northeast. Its major axis is parallel with the coast, and its greatest width is in the neighborhood of Charles- ton.' The jDrincipal deposits are located in Berkeley, Dorchester, Charleston, Colleton, and Bcanfort coun- ties.'^ So far as occurrence in commercial quantities is concerned, their distribution is confined within narrow limits. The_v are found at the bottom of rivers, 20 to 30 feet in depth, and on land they occur at an elevation but slightly above mean tide. The rock of commerce occurs alwaj^s above the marl and is known as land or water rock, according to its location. The water rock is darker in color and harder than the land rock, and is frecj^uently found in a layer or sheet of cemented or tightly compacted nodules overlj-ing the marls at the bottom of rivers and creeks, where it either forms the bottom itself or is overlaid by a deposit of mud of greater or less depth. The land rock is found gener- ally at a depth of from 2 to 10 feet below the surface of the soil. It occurs in masses or nodules varying in size from that of a potato to several feet in diameter. These nodules are rounded, rough, indented, and fretiuentl3' perforated with irregular cavities, and in color they ' Phosphates of America, by Francin Wyatt, Ph. D., page 49. ^ South Carolina, by Harry Hammond, page 47, and map. vai-y from olive or bluish black to a yellowish or gray- ish white. By analysis they are found to contain 55 to 61 per cent of phosphate of lime, 5 to Ki per cent of carbonate of lime, 2 to 10 per cent of organic matter and water, with small quantities of fluorine, iron, mag- nesia, alumina, sulphuric acid, and ,spnd. This daiid rock is found in a loose layer varying from a few inches to 30 feet in depth, and averaging about 8 inches. It occurs in sand, mud, clay, or peat, and is often inter- nungled with numerous remains of land and marine animals. Among the former are the bones of the mastodon, elephant, tapir, deer, and the domestic ani- mals, the horse, cow, and the hog.' The great bed, or series of beds, of phosphate rock which was later destined to supply the civilized world with the chief part of all the phosphate of lime used in the manufacture of commercial fertilizers was discov- ered, or rather its value was first definitely established, in 1867.* To Dr. St. Julian Ravenel, of Charleston, this honor has ])een accredited. However, forty years be- fore, Robert Mills forecasted this discovery, saying, that "' besides gypsum, we ma3' also expect to find in that part of the state (the Atlantic seaboard), the same kind of marl which has so greatly contributed to enhance the value of the poor lands of New Jersey, by the fertilit}' which it imparts to the soil.""' At the close of the Civil War Dr. X. A. Pratt, of Georgia, formei'ly connected with the Niter Bureau of the Confederacy, visited Charleston with tlie object of starting sulphuric acid chambers. His attention was directed by Doctor Ravenel, who had already noted the presence of phosphate of lime in considerable quantity ill the marl stones, or nodules, near Charleston, to sam- ples of the rock taken from the Ashley river region. Doctor Pratt analyzed the specimens and found that the rocks contained a sutficieutlj' high percentage of phos- phate of lime to render them of merchantable value." As soon as the commercial importance of the deposits became generalh' known other available beds were located, and considerable capital Avas employed in devel- oping the industry by mining the crude rock, and exporting the product or manufacturing it into super- phosphates. Later the beds of many navigable streams wei'e found to be largely paved with the \-aluable sub- stance. In 1870 the mining for this river rock beo-an, and was developed through the introduction of dredg- ing and grappling apparatus into an industry of equal importance with the mining of the rock on land.'

From the first the industry yielded large protits. tind for a period of two and a half decades was prosecuted with great energy. Beginning with a production of long tons in l.SCT, it had increased in ISTT to 163,000 tons, and ten years later to -±80,5.58 tons, reaching the maxinuim in Issii. with 541, til:5 tons. In 18',)(l the out- put from the Florida mines had so increased that the condition of the industry in South Carolina became serious, and hy 18'.»2 what was once at a premium hecame a drug. The Florida developments had not only caused an (>\-erproduetion of high-grade rock. ])ut luul forced upon the market immense quantities of lower grades, wdiich could be used \vithout any enriching material. The reason why 75 per cent and SO per cent rotdv should rrttiin an exceptional value no longer existed, luid so it sank to a common level with the poorer products.' The adoption by the phosphate miners of the state of di.'speratc measures to stem the tide and shut off competition by cutting the prices, only resulted in furthei' I'mbarrassment, until the nnirket price dropped lielow the cost of production, and it became possible for them to remain in the market only ))y sell- ing at a very tangible loss." The industry received further setbacks through a royalty dispute between the state and river miners and through a cyclone, August 37, 1893, which severely in- jured the mining i)lants, especially those of the I'iver miners at Beiuifort. ' Barring a temporary setback in 190(» to the industry in the state, due mainly to scarcity (jf ti-ansportation facilities and high ocean freights, a gi'adual reco\'ery has continued up to the present year.' s!l H-rniix cri/sfiill iiir riirl's. — The granites and gneisses arc wiilely disti'ibutcd and extensively (juarried above the fall line. The term granite is generally applied to all these rocks by the miners of the state. The gran- ites proper are found in abundance and their outcrops lie along three nearly parallel lines. On the most southern of these lines they show themselves among the .sand hills at Graniteville on Horse creek, Aiken county, and thence at various points, in a northeasterly direc- tion, to Columbia. Many j'ears ago notable quarries for building materials began to be worked on this line at Graniteville and at points in Richland county.' The second line of outcrop extends from the neigh- borhood of Harris creek, Edgefield county, across New- ))erry, Fairfield, and Kershaw counties to the north- western corner of Chesterfield. Here, also, quarries of excellent granite, fine grained and easy splitting, have been found, especially in Newberry and Fairfield coun- ties, where there are inexhaustible (piantities of the best building granite. A flesh colored porphyritic granite is f(nind in Kershaw. In Edgefield and Lan- caster counties it becomes coarser and syenitic in char- acter. The third line of outcrop stretches through Laurens, Union, and York counties. In the vicinity of Union the granite is of exceedingly tine grain and well adapted for architectural purposes, but most of it on this line is characterized by a coarse porphyried structure." Granite quarrying is an important indus- try in the state, being exceeded in value of product only by the mining of phosphate I'ock. <'hii/. — Clays of manj' varieties are found widely dis- tributed and constitute perhaps its greatest actual and prospecti\c resource, lieing suscepti1)lc of greater ex- tension and de\'e]opnuuit than any othei- mineral." The cliiys were among the first in the I'nited States to attract attention, and early in the nineteenth centurv, prior to lS3fi, a Doctor (iarden carried a small shipment of South Carolina kaolin to England and manufactured it into china ware.' While common, or Itrick, clay of excellent quality is fc)und in almost every neighborhood, the state's principal wealth in clays lies in the extensive deposits of kaolin remarkable for purity. The sedi- mentary kaolins are widely distributed in the Savannah river area, the Santee area, and the Edisto area, in the counties of Aiken. Lexington, Kichland, and Kershaw. In this region there are extensive beds of pure white kaolin exceeding 18 feet in thickness, and affording 98 per cent of clay substance, which reciuires no other preparation than drying." The Savannah river area affords perhaps the most remarka})le exposures of sedimentai-y kaolin in the United States. In .some places they are practically con- tinuous for miles. From Hamburg to Aiken extends a zone 1-4 miles long by 5 miles wide.'' The l.)eds varv from 5 to 25 feet in thit'kness with an oAMudmrden of 'The .Miiici^il liidii^frv, 1S!)2, \'nl.

The kaolin is moved in limip form to the drj' sheds, where, after exposure to air and light for a few weeks, it is packed in casks of 1 ton capacitj' and shipped to the consumer. These deposits probably represent the largest body of clay closely approximating kaolinite to be found in the United States.' In the Savannah river area of the coastal plain outside of the distinctive clay zone pertaining to the Cretaceous and Eocene formations, there are beds of clay of eco- nomic importance. At North Augusta and Hamburg a large deposit of alluvial clays occurs, which is excellently adapted to the manufacture of brick and the coarser stonewares.'^ A zone of older clays occurs approxi- mately parallel with and about 30 miles distant from the coast. These claj's are often fine grained and vary in color from pale yellow to a mottled hlue; they are associated in many instances with coarse sands. Their average elevation above the sea level is (io feet. These beds are developed near Garnett, and are adapted to the manufacture of tiling, face brick, and common brick."

Auriferous gravels are found in many localities, but chiefly in York, Union, and Spartanburg counties.' The first consignment of gold from the sands of this state reached the LTnited States Mint in the latter part of 1829.* The first recorded discovery of gold in the state, however, antedates this by three years, and was ' Clays of South Carolina, pages 49, 50, and 81.

In 1S30 and 1831 numerous workings were under way in the state, especially in Lancastei- and Chesterfield counties, where, in the latter, at the Bi'cwer mine, even at this early date, from 100 to 200 men were employed.'' In 1859, 20 gold mines had been opened in the talc slates of Chesterfield and Lancaster counties, and 10 in the same slates in Abbeville and Edgefield, among the latter the celebrated Dorn mine from which more than a million dollars in gold has been taken. In Spartan- burg, Union, and York counties there were 19 and in Pickens and Greenville 8 others." Gold mining, except in a few localities, remains prac- tically as it stood in 1861. One notable exception, how- ever, is found in the Haile gold mine, located in Lan- caster county, which for many years has been perhaps the most consistent producer east of the Rocky moun- tains. The small sil\-er production in 1902 was also from this mine. Limestone occurs and to some extent has been cjuar- ried in York, Spartanburg, Laurens, and Pickens coun- ties.' It is used for bridge work and in crushed form for road building." However, owing to the abundance of granite for these purposes, it is used chiefl}' for burning into lime. A few tons of manganese ore were mined near Green- wood in 1902, the mineral in great purity and abund- ance having been found at the old Dorn gold mine in Edgefield count}' and also in Abbeville, York. Laurens, and Anderson counties.'' Precious stones have been found at a number of places in the state. The first garnet found in the United States was picked up in Abbeville county, about 1825.* It was of a greenish yellow color. Garnets have also been found in Spartanburg count}'; rubies in Pickens; tourmaline in York, Edgefield, Laurens, Anderson, and Oconee; beryl in Edgefield and Laurens, and zircons in Abbeville and Anderson. * South Carolina, page 1H4. * Ignited States Geological Survey, Sixteentli Annual Report, Part III, page 257.

Gold. — The earliest authentic date of the finding of gold in the Black Hills is July 27, 1871, when small quantities of the precious metal were found in the bed of French creek, in Custer countj', bj' miners accom- panjdng the expedition of Gen. George A. Custer. From certain stories, still current, it would seem that some of the Sioux Indians and a few white men knew of the presence of gold in this region before 1871, but nothing definite is known concerning the actual facts. A few weeks after the Custer expedition, other depos- its of the precious metal were found, on December 23, 1871, about 3 miles below the present site of Custer, by a party entering the Black Hills region for settlement. Much prospecting was done in this vicinity during the winter, though little gold was found, and in the spring of ISlb the party was forced by the military to leave. The Black Hills country, then included within the Sioux reservation, was not open to settlement, and the Government made every effort to prevent prospect- ors from entering. This policy only intensified the desire to explore the region, and as a result of the widespread interest the Government, early in 1875, organized a special survey' for the purpose of learning whether the mineral and other natural resources of the region warranted its purchase from the Indians. The fii-st authentic published statement of the finding of gold in the Black Hills was in a letter dated June 17, 1875, from the geohjgist in charge of th(! sui-\'ey to the Commissioner of Indian All'airs at Wasliington, I). C., and which was first published in the Mining and Engineering Journal. The gold referred to in this letter was found June 12, 1875, in terraces or bars of quartz gravel, on the north bend of Castle creek.' About a month later important discoveries in the placer deposits of Spring and Rapid creeks, northeast of Harneys peak, caused a rush in that direction, which was the first real stampede in connection with the gold excitement in the Black Hills. B3' this time several hundred prospectors had succeeded in gaining access to the region, and of this number more than a hundred staked out claims on Spring creek and commenced pan- ning for gold. The results of the survey having established the fact that the Black Hills region was of much greater value for mining purposes than it ever could be to the Indians, the Government finally purchased it from the Sioux for $4,500,000, and opened it for legal settlement February 2S, 1877. The discovery in the fall of 1875 of the rich placers of the Deadwood region, in Lawrence county, and, a few weeks later, of the rich conglomerate ores and of the great impregnated zone known as the Homestake Belt, indicated the permanent wealth of thatiDartof the Hills and the tide of settlement turned accordingly northward from Custer. Since 1S75 Lawrence countj' alone has far surpa.ssed the balance of the region in the production of gold. For ten years after gold was discovered the Black Hills had no railway facilities of an}' kind, but at the present time the northern part has excellent I'ailway facilities, which fact has occasioned the opening up of manj' important mines. The central and southern hills are not so favored. The gold bearing quartz veins are found chiefly in Pennington and Custer counties, in the central and southern part. Lawrence county, to the north, also has some valuable quartz veins. The ores of the im- pregnated zones are of great importance, one of them, the Homestake Belt, having furnished approximately three-fourths of the total output of gold in the Black Hills. The Homestake ore bearing area is an irregular belt lA^ miles long and one-half mile wide, near Lead city, forming perhaps the largest and most easily worked mass of low-grade gold ore in the world. In Lawrence county only have the ores of the impregnated zones been worked continuously for any length of time though many claims, in Custer and Pennington counties, are said to carry as high values as the Homestake ore. The cement ores within the Hills west and southwest of Deadwood were discovered in the early part of 1876 and in the same year the first quartz mill brought into the Hills reached Deadwood. The siliceous ores are 310 MINES AND QUARRIES. found only in the northern part, the producing ores lying- in Lawrence county. Placer gold is found in the gravel bai\s of all the streams and in the various terraces lining their valleys. The richest deposits, however, are either exhausted or can no longer be worked extensively with proht lie- cause of the lack of water supply. Associated with the gold in the placers are garnets, hematite and limonite pebbles, columbite, tantalite, cassiterite, and other less noticeable minerals.'

Tennessee has long been conspicuous as a mining- state; for more than one hundred years its great wealth of iron ore deposits has engaged the attention of miners. The coal lields, comprising almost one-eighth of the total area of the state, are practically inexhaustible and have been worked extensively. Since the discovery of phosphate rock earl}- in the present decade its mining has grown until the state's output of this mineral has become second only to its production of coal. The marble deposits of the state have long been famous. Their earh^ development brought the state into promi- nence, and with the increasing demand for '^ Tennessee" marble the industry of its quarrying has grown steadily. Another important branch of mining industry is that which has developed around the valuable and extensive deposits of copper ore in the Ducktown district. Manganese is of frequent occurrence in various parts of the state, chiefly in the eastern section in association with the iron ores. The first manganese ore mined in the United States was produced near AVhittield, Hick- man county. The mine was first worked in 1S87, and the output was used for coloring earthenware. The two sections from which manganese oi'es have been taken in commercial quantities are the vicinity of Sweet- water, Monroe county and in Unicoi county.' Lead and zinc ores occur at numerous ])oints in the eastern and middle parts of Tennessee, and a half cen- tury or more ago in the Vallc}- I'ange- west of the line of Red Knobs lead mining gained considerable head- ' United Ktatea (Jeolot^ical .Survey, Sixteenth Annual Keprirt, 1894-95, Part III, page.s 423 an.l 4L'4.

The industry lias not been l•e^■ived, although deposits of galena occur that seemingl}' would warrant commercial exploitation. Interesting featui'es of this locality are the old and (jiiite i^xtensive '"diggins," about which the oldest inhabitants and the Indians )je- fore them knew nothing." It has been surmised that these excavations were made in a search for galena. Whether the object was to secure galena or other min- erals, these workings point unerringly to an era of mining activity which antedtites both history and tradi- tion, and most probably was cotemporaneous with the still more extensive^ and systematic operations in the mountains of North C'arolina, and with prehistoric cop- per mining in the Lake Superior region. The deposits of zinc ore, especially those in the vicinity of Knox- \ille, have be( mining industry, using as their raw material the prod- ucts of mines and quarries.

The belt in which these coal measures occur is coexten- sive with the Cum()erland table-land and varies in width fi'om 71 miles at the northern boundary to tA) miles at the Gecjrgia and Alabama state line.^ In this belt the industiT of coal mining has Ijeen developing since long before the Civil War, during which its growth was temporai'ily interi-u^jted.' Pi-actically all the mining of these earlier years was on a petty scale, and outside of Nashville and Memphis very little coal was used, except for blacksmithing purposes.' The industry did not reach a scale of any considerable im- portance until some fifteen years after the war,'' but it has developed steadily sint'e. In 1892 its progress was seriously interfered with by strikes. Since 1893 production has increased rapidly, the output foi' 1902 being 50 pei' cent greater than that for 1897, and more than double the production at the l)eginning of the decade.' Nineteen counties of the state are embraced wholly or in part within the coal belt, and the range of the industry has expanded until coal is produced in practically all of these counties. In Campbell county is a part of the famous Jellico steam-coal field. The Sewanee vein, one of the mo.st important, is extensively worked in Grundy county. Much high-grade coke is made from this product. Other counties in which extensive coking establish- ments are under way are Claiborne, Hamilton, Marion, Rhea, and Roane." Eighty-eight per cent of the A'ield in 19(.»2 was from the following counties: Anderson, Campbell, Claiborne, Cumberland, (jrundy, Marion, Morgan, Rhea, and Scott.

Phosphate rocl\ — Tho phosphate vock mined in tliis state has been chissitied into three o-roups or ^■arietie.s, according to color. The.se are blue rock, which occui'S mainly in Hickman county: white rock, as typified by the deposits occurring in Perry county; and l)rown rock, deposits of which are confined principally to Maury county.' Rocks cOTitaining varying percentages of phosphate occur in se\eral other counties in the phosphate rock region, whii'h extends from the viciidtv of Nashville, south to the Tenni'ssee river. The discovery and exploitation of the deposits of this valuaVjle mineral in the state constitutes, in the main, a repetition of the events attending the discoverv of phosphatic rock in both South Carolina and Florida. In all these cases the valualile phosphatic contents of tlu' rock became known ))y accident. The existence of the rocks was a matter of conmion knowledge, and their peculiarities, at least in the case of South Carolina and Tennessee, had been the subject of extended study and investigation bv geologists. A remarkably accu- rate description of the physical characteristics of the phosphate deposits of Tennessee was given by Doctor Saff'ord, in 1S69, in his Geology of Tennessee. Their chemical nature and great commercial value, however, remained a secret for a quarter of a centui-y longer. Certain kinds of phosphate rock in Tennessee lia\e been used for many j'ears in building operations re- quiring stone. An object of interest to visitors to the fields at present is a stone house made almost entirely of phosphate rock many 3'ears ago by a religious recluse.' The discovery of the deposits, the development of which marked the beginning of phosphate mining in the state, occurred in October, 1.SH3. During that year Messrs. L. Bates and R. Childs had been prospecting for coal in this sectio?. and a Mr. Harder, while fishing in Swan creek in Lewis county, foimd some pecidiar looking rocks, which he sent to these coal prospectors for examination. Thinking the rocks indicated coal these pi'ospectors shipped them to Prof. J. (.'. A\diarton, an analytical chemist of Nashville. Cpon examining them the chemist found one of the specimens to be a high gi'ade of ])hospl)ate rock.'' ^^'hen the disco\'er\' Ix'came known tlie scenes enacted in Soutli Carolina and Florida were repeated. Prospectoi's ;uid speculators were early fin the ground, and other disco\'eries ((uickly followed in all directions. By July, LS',)4,'' several com- panies had been organized, extensive tracts of land had been purchased oi' leased, and the industry of phosjihate mining was well undei- way. In the lattei- part of this year tlje |ihosphatc rock of Temiessee first became a dis- tinct factor in the market. About 45,000 tons were mined and shipped between .July, lHi)4, and July. bsH,5.

S. Q. Weatherhy, while passing along a road near Mt. Pleasant, in Maury county, obserx-ed in the deep cuts a thinly laminated rock that to him suggested zinc ore. Actuated mainly by curiosity, and with no thought of making any valuable discovery, he broke a piece to study its structure, and found that instead of confirt)i- ing his impression as to zinc ore it presented a granu- late', " Mineral Resources of the riiited States."] Founds. 1890.

Marljle. — The marbles of Tennessee, forming one of the state's principal mineral resources, are widely dis- tributed. They have been quarried in the eastern, middle, and western sections of the state."' The chief deposits, however, are comprised within an almost un- broken zone or belt 20 miles in width and more than loo miles in length, situated in etistei'n Tennessee, with Knox county as its center." Within this range the supply of marble is practically inexhaustible. There are many kinds suitable for the various uses to which marble has been put. In color almost everj^ tint and shade between white and black is found in a great va- riety of combination. There is no record of the earli- est marble working in the state except that chiseled into the first products of the industry. These old tombstones, still sharp and clear in outline, scattered through the churchyards of the region, and especially those around the First Presbyterian church in Knox- ville, serve the double purpose of carrying the date of their manufacture back into the morning of the nine- teenth century and of affording the most convincing proof of the enduring qualities of the marble from which they were cut. Marble quarrying along sys- tematic lines dates from April, 1838, the first quarry being opened at Rogersville, the seat of Hawkins county."- OrA'ille Pace, a Yankee clock peddler,"' was elected president, and the company was organized for the purpose of sawing marble and estaljlishing a marble factory in the \'icinity of Rogersville." This quarry was located on the line of the stage road, and 'The United States C4eological Survev, "?ilineral Resources of the United States," 1883-84, loage 277.

The house \vas known as "Marble Hall," and is still stand- ing, being \ised at present as a residence.' A block of the light mottled strawberry variet}' was sent to the builders of the "Washington Monument; it was inscribed "Hawkins County Block." Another block, sent by authority of the legislature, was called the "Tennessee State Block.'" These attracted the attention of the building committee of the Capitol at Washington, D. C, and although the_Y had specimens from all the then known marble deposits of the country, they decided in favor of the East Tennessee marble." Following this decision an extensive ([uarry was opened by the Government at a point near I-vogersville where the Holston river intersects the marble range, and from here many thousand cubic feet were taken. It was used in constructing the balustrades and col- umns of the stairs holding up to the House and Senate' galleries, the walls of the marble room, and other 2)arts of the building. About one-half of the ornamental material in the Capitol is of Tennessee marble.'' This unequaled means of advertising at once brought the state into national prominence as a marble producer. In 1902 Tennessee ranked second in the production of marble for interior dec. Except in the use of common clay for brick, very littl(> mining of this mineral is carried on. A large [ bed of what is claimed to be kaolin or porcelain clay owwvn in the state," T)ut there was no production from it in 19(»2. The production of clay in 1902 consisted of pipe. ball, fire, and .stoneware clay, and was mined to .some extent in Carroll and Hardeman counties, but chiefi^' in Henry county. While deposits of c(jpper ore occur at numerous places in the mountain region, the great deposits are in the Ducktown district of Polk county, in the extreme southeastern portion of the state. These ore deposits are not true fissure \'eins; the}' are great lenticular masses of ore and gangue material h'ing conformably between strata of country^ rock. These masses or veins occur generally in long ranges oi' belts, one succeeding another longitudinally in approximately the same line, and their feather edges not infrequt'ntlv overlap though thrown apart liy intervening rock.' The discoverv of copper in Polk county followed the discovery (jf gold made some years pre\'iously on Co(|ua creek. It was in the search for the latter metal that one of the gold hiuiters. Mr. Senmions, in 1S13, foiu)d crystals of red copper ore while punning the gra\els for gold in a branch at a point where the Hiwassee copper mine was later opened. Further investigation was carried on by a ^Ir. (irout and several rich specimens of native copper were found. In IslT a (terman miner named W^d)er secured possession of the property and made the first shipment of copper ore from the district. This consisted of '.^0 casks and was sent to the Revere Smelt- ing Works, near Boston. Before he had learned the real value of his shipment the miner left and operations ceased. In Is-t!) Mr. John Caldwell reached the dis- trict in a search for copper ore, and to him, perhaps, more than to any other is due tht> credit for the devel- opment and exploitation of these valuable and exten- sive deposits. The first mine opened in the district was the Hiwassee in August, ls,5(i. Next came the Cocheco in October of the same year, and one year later the Tennessee. In ls.5i' two other mines were oiK-ned. In ls.")3 this number was increased by 6 others with 3 more in ls.5-1:. ' When the almost insu- perable obstacles in the way of the transportation of machinery through the wild inoiuitainous countrv to the district and the haiding of the product from it are considered, this rapid development is all the more reniiirkable and indicates plaiidy the richness and extent of the deposits. By the end of Se])tember of the following year, 1K55, 14,291 tons (.)f ore, worth nioi'e than a million dollars, had been shipped from the district. The Ducktown district continued to develop- to the industry of mining was addeil that of MneltiiK>- and later rolling mills were constiticled.

As a result of this piolonged suspension the mining properties suliered greatl}', skilled laborers were dispersed, and, on the whole, con- ditions in 1865 were altogether unfavorabk> for a resumption of activity. However, the excellent quality of the Ducktown copper, and the demand for it, fur- nished a very potent stimulus, and soon operations were under way on an even wider scale than before. The copper industry was one of the first to recover from the effects of this period of great industrial depression, and has continued to be an important factor in the state's mineral development since.' Fluorspar occurs in numerous places in the state and especially in Smith, Trousdale, and Wilson counties. Some of the deposits are of commercial importance. Fluorspar mining is new in the state, being a develop- ment of the last one or two years.'' The only section of the state in which gold has been found in an}' important quantity is the southeastern part between the French Broad river and the Georgia line.

Considerable placer mining was done at this time and some gold has been mined each year since, but the industr}' is of minor importance.'' The only production of crude mineral pigments re- ported for 1902 was a small quantity from James county. The beginning of the production of natural gas in the state is of quite recent date, and the only report in 1902 was of a small anjount in Franklin county. The first successful borings for petroleum in the state were probably those in the southern part of Overton county in 1.S66.' The industry at present is of minor importance, the total production reported in 1902 being a small quantity from Fentress county. The workable sandstones of the state are not widely distributed.

Petroleum and bituminous coal together represented more than four-tifths of the total value of the mineral production in the state. The gypsum reported in Texas was about one-tenth that of the entire Cnited States production and ranked third in importance among the minerals of th(.' state. There were but two establishments reporting, and there- fore the separate statistics for this industry are not published. Quicksilver ranked fourth in value among the minerals of the state, the value of the production amounting to 16.4 per cent of the total for the United States. Follow- ing in the order of their importance may lie mentioned the production of cement, limestones and dolomites, sandstones and quartzites, gold and silver, siliceous crys- talline rocks, natural gas, iron ore, clay, and asphaltum and bituminous rocks. A large number of minerals, for wdiich no commer- cial production was reported diu'ing 1900, are known to occur in Texas. Among these may be mentioned the following: Antimony, asbestos, bisimith, copper, feld- spar, garnet, manganese, marble, molybdenum, slate, and talc. Agati;, amethyst, opal, and tourmaline have also been found in tin: state. (31S) Development work was carried on during the j'ear at 71 mines, quarries, and wells by 51 operators, their at- tention being almost entirely directed to petroleum and gas wells, coal mines, and sulphur and pyrite mines. These tiperators paid $37,209 to their 36 salaried offi- cials, clerks, etc. They also gave emploj'ment to 48 wage-earners and paid $46,766 in wages. The amount expended for contract work was $245,542; the miscel- laneous expenses were $2'.t,912; and the cost of supplies and materials was $51,679.

Petroleum. — The presence of oil in tar spring-.s, oil seeps, etc., in Texas had been known for many years, but the first record of the discovery of petroleum in quantities sufficient for use seems to have been about 1867, when it was found at a point 15 miles southeast of Nacogdoches.' But little attention was paid to these petroleum deposits until 1S83. During the period from 1887 to 1890, 90 wells were drilled in the vicinity of Nacogdoches. Statistics of production first appeared in 1889, when i8 barrels were reported, with a valuation of %Z¥). About 1 894 oil was accidentally found at Corsicana, during the sinking of an artesian well.*^ A company was formed and other wells were sunk, oil being dis- covered in 1898 at a depth of l,0-±(> feet. The drilling in this locality is entii'ely through a hard clay, and the oil obtained, resembling the Kan.sas product, is better than the Ohio oil, but not as good as the Pennsylvania. The Corsicana product has been used exclusively for fuel and in the manufacture of illuminating gas in Dallas, Houston, and Austin.'

The unexpected outburst of a tl-inch gu.sliei- in J9((l near Beaumont, in Jefferson county, was tlie sensation of the petroleum industry in the United States. Be- ginning on January 10, in nine days a stream 160 feet in height emptied out an estimated quantity of r>(.)(), ()(.»() barrels of oil before being capped. As a result of this wonderful find many companies were formed, drilling commenced without delay, and in less than six months there were 211 operators in that county. The eleva- tion knf)wn as Spindle Top embraces about 12.5 acres, and is in its highest part 40 feet above sea level; the surrounding plain slopes southward 18 miles to the (xulf of Mexico. This was the scene of most active operations, and land was divided into small lots selling for fabulous prices.' At Sour Lake, in Hardin county, a slight development was i-eported in 1893, but it was not until 1901 that any consideral)le results were obtained. A gushing well, flowing an 8-inch stream, was drilled earlj- in 1902, and during the year a number of wells have been completed and the value of the field has been fully established. At the Saratoga well, 12 miles northwest of Sour Lake, successful development work in 1902 was reported. In Bexar county a small quantity of heavy oil was produced and supplied a local demand. Work in the Nacogdoches district, in which there were the first indications of petroleum in the state, has been practically abandoned, and no production was reported for l!t02.''

A further investigation in 1S46 of the Trinity river district, 30U miles above (ialveston, resulted in the finding of coal in more extensive measures than was anticipated, l)oth anthracite and a semibituminous coal resembling cannel coal, being dis- covered.' In 1859 the first geological report of Texas contained an estimate as to the area of the coal fields in the state, and in 1866 the coal seams at Belknap were mentioned as well as a bed of coal about 6 miles north of that place.' Coal production in Texas during 1902 maj' be said to have centered in Erath county, where the amount re- ported exceeded that of all the other counties in the state. Webb county, in the southern part of the state, was second in importance, and Wise county in the northern part of the state, ranked third. Maverick county, on the Rio Grande river, and adjoining Webb county, was fourth, and Parker county, between Erath and Wise counties, ranked fifth, and a small production was also reported in Eastland county. These were all bituminous localities, and their total production was valued at over $1,300,000 during 1902. The secondary coal fields of Texas, for which produc- tion of lignite was reported during 19<)2, wen' found principally in the following counties, ranking in the order named: Milam, Bastrop, Medina, Robertson, and Wood. Several other minor productive lociditie.s were reported. Coal measures are found in Texa.s in thre<,' districts. The northern or })ituininous field is the southern ex- tremity of the Western coal liasin of the United States; the semibituminous seam along the Rio Grande is .second in importance; and larger than either in extent and thickness, but least in \-alue of production, is the lignite field, lying in the central part of the state, and including over fiftv counties in Avliole or in part.'' The following tal)le, compiled from the reports of the United States (reological Survey, shows the annual production of coal in Texas from ISS:-] to 1902: Table .5. — AhuimiI iirddncliim (ifcunl, hitnminoiix: ISS.I In I9(U.

There was quarried in Texas during- 19(i'2 limestone and dolomites to the value of $'2l!i. — The siliceous crystalline rocks quarried in the state during 1902 were obtained in Llano and Burnet counties, in the central part of the state, near the towns of Llano, Kingsland, and Burnet. Both fine and coarse red granite were quarried, the lat- ter corresponding closely to that obtained from Platte canyon, Colorado. Red and gray granites occur in (iil- lespie county, although no production was reported from that locality during the year.'' The value of siliceous crystalline rocks quarried in Texas in 1902 was reported as $60,003, and about three- fourths of this stone was used for monumental pur- poses. The remainder, amounting in value to !|13,78'±, was used in building operations. Natural gas. — While prospecting for oil and gas in the southwestern part of Washington county during 1879 a well was drilled which gave a strong flow of nat- ural gas at a depth of about 160 feet. No practical use was made of this gas, and the first commerciallj' suc- cessful well in this locality was not drilled until 1888.' The production during 1902 was all obtained in Jef- ferson and Navarro counties, in the Beaumont and Cor- sicana oil districts. The value of the output reported hy the 14 wells in operation during this year was 114,953, indicating a decrease in comparison with 1900 and 1901. In some instances the gas obtained was used to force the flow of oil wells. It spread over the surface of the 'Stones for Building and Decoration, page 164. 2 Ibid., page 83.

Hardeman county was the oidy locality where gypsum or gypsite was quarried, and the pi-od- uct was sold chiefly as cement oi' wall plaster, although a small amount was reported as consumed in making- plaster of Paris. Cement also is (piarried to a considerable extent in Dallas and Bexar counties, and in value of production ranks among the important mineral products of the state. Silver bearing quartz is mined quite extensi\rely in Presidio county, in the locality of the Kio Grande. Blanket deposits in limestone are found in pockets and in some places in the strata. The ore is transported in wagons to the town of Shaffer, where it is reduced to the metallic state by amalgamation. Small quantities of stoneware and fire cla}' were mined by individuals near Elmendorf, in Bexar county. The stoneware clay was not prepared at the mines, but was sold in the raw state to a pottery establishment. Deposits of asphaltum and asphaltic rock exist in Texas, but the onl^' production during 1902 was a small amount of liquid asphaltum obtained from test holes sunk b\' an oil and development company in Travis county. Iron ores are found in a number of counties in Texas, and some of the product is of Bessemer qualitj-. In character, the deposits are a brown hematite or bog ore, and the occurrences are found in a continuous and persistent ledge covering the mountains of the eastern part of the state.' According to the first record the iron industry in Texas was started in Cass county, where a blast furnace was in operation for some years prior to 1859. A number of other furnaces and bloomeries were also reported about this time, those in Cherokee county, near Rusk, having been established during the Civil War.^^ * Annual Report of the Dallas Commercial t'lub, 1899, page 37.

Tlie mineral resources of Utah constitute one of its principal sources of wealtli. The state ranked third in 1902 among the states and territories in the value of gold and silver production and fourteenth in the value of all minerals. The development of the mineral resources of the state has been slow, principally because of the lack of trans- portation facilities and to the fact that some of the greatest ore bodies arc in almost inaccessible regions. However, the activity in developing pi'operties within the past few years has begun to attract capital, and when the immense bodies of coal, iron, copper, and other ores that the state is known to contain are proji- erly worked, Utah will rank among the foremost mineral producing states of the Union. Gold and sih'cr mining has been developed to a greater extent than any other branch of the mining industry, and the product of this class of mines in 1902 amounted to §.S,500,904, or 6S.7 per cent of the entire production from the mines and quarries of the state. The other minerals in the order of their importance are: Coal, bituminous; copper ore; limestones and dolomites; .sandstones and quartzites; cement, asphaltum, and bi- tuminous rock; sulphur and pyrite; gypsum; iron ore; maride; siliceous crystalline rocks; and clay. Natural gas has been produced in Utah, but the wells which were located near Salt Lake City became choked bv the decomposition of the slate forming their walls, and the industry in the state has practically been aban- doned.' ' United States GeoloKical Survey, United Statci^," HMll.', jiaf^e 6.5.3. ' Mineral KeHources of tiie The list of minerals found in Utah liut not worked commercially is a long one. including slate, antimony, cinnaliar, mineral wax, alabaster, alum, natural gas, precious stones, tripoli and pumice, saltpeter, borax, and many others. In ^Nlilltird county is found the only known deposit of lump pumice stone in the United States. = Among the gems to l)e found are some of the most beautiful and brilliant crystals of the North American to])az. These are found in considerable (juantities on Thomas mountain, Deseret, an isolated and arid eleva- tion about ti miles long in Millard county. These crystals are larger than those from (California; are always white, and evidently have been decokirized l)v heat or exposure to sunlight. They are equally as l)ril- liant as those from San Luis Potosi, Mexico, which they closely resemble.' Besides the work done at the productive mines and (|uarries in 11102, development work was done on 273 mining properties, 266 of which were gold and silver, the othei's l)eing distributed among the industries of iron and manganese ores, marl)le, and petroleum. The operators of these properties employed 211 salaried officials, clerks, etc., to whom they paid $162,74:1 in salaries. They also gave employment to '.166 wage- earners, and paid them $920,621 in wages. The work done by cOntrtict cost $162,716; the miscellaneous ex- penses amounted to |133,.551. and the cost of su]>plies and materials was $168,505.

The value of the output of the productive mines and quarries of the state in 1902 was $12,378,350, or 36.9 per cent of the combined value of product of manufactures in 1900 and mines and quarries in 19o2. In 1902 the operators of the productive mines and quarries of Utah gave emplo^auent to .5, TIM wage-earn- ers and paid $5,089,122 in wages, and in 1900 the manu- factures of the state gave emploj'ment to 0,015 wage- earners and paid $3,388,370 in wages. The total average number of wage-earners employed in mining and manu- factures was 12,327, and $8,477,-192 was paid in wages. Mining, therefore, employed 40.3 per cent of the wage- earners and paid 6() per cent of the wages, while manu- factures contributed 53.7 per cent of the wage-earners and paid 40 per cent of the wages.

For 1902 the reported value of the output of the mines and quarries of the state was $5,904,705, or 9.3 per cent of the combined value of the state's manufactures in 1900 and mining and quarrying in 1902. As reported at the census of 1900, the manufactures of the state employed on an average 29,455 wage- earners during the year and paid $12,237,684 in wages. The corresponding figures for mines and quari-ies in 1902 were 5,398 wage-earners and $3,114,399 paid in wages. Comparing the figures for manufactures and mines and mining, it is seen that manufactures em- ployed 84.5 per cent of the wage-earners and paid 79.7 per cent of the wages, while mines and quarries gave employment to 15.5 per cent of the wage-earners and paid 20.3 per cent of the wages.

Marble has l)een quarried in Vermont for more than a century, the earliest authentic record of such work having been made in 1785.' In 1902 the state's output of marble came from the quarries in Rutland, Benning- ton, Frankhn, Chittenden, and Grand Lsle counties, though the stone is of known occurrence at man}^ other localities in the .state.^ The most famous of Vermont marble beds are those of West Rutland, and the name "Rutland marble" is used to designate either that from these quarries or from Proctor.^ Important quarries are also located at Dorset and East Dorset, in Benning- ton count}^ Much of this stone is of the finest quality and is used for monuments, decorative work, and for statues, as well as for genej-al building purposes.* The color effects of Vermont marble are many and beautiful, ranging from pure white through all shades of blue, and sometimes green, to deep blue-black, often being beautifully mottled and veined. The dark varieties, as a rule, are the most durable and valuable, although the white is in the greatest demand for mon- umental and statuary work. This stone differs from the marble of Ital_v in being of a dead white color and lacking the luster so characteristic of the Italian prod- uct. Marbles of different shades of gray, with sinuous veins, as well as some of red, pink, and chocolate colors, plain and mottled, are also found. ^ Black marble is found at Isle La Motte, in Grand Isle county. Since the deposits in Vermont are of great thickness, the quarries occasionally reach a considerable depth, or in following the vein the opening is pushed far under a hill and forms a cavern, the walls and roof of which are supported at intervals by enormous piers left for that purpose. The value of the marble, both rough and dressed, that was used for monumental purposes, amounted to $758,390, or 28.8 per cent of the total, while the value used for building purposes amounted to $433,265, or 16.5 per cent of the total. Siliceovs cry.italline rocks. — The occurrence of exten- sive granite deposits in Vermont has been known since the state was first settled." Notwithstanding this knowl- edge, the quarrying of granite as an industry of im- portance has had its growth almost entirely since 1880, although small quantities of the stone were taken out much earlier.'

In fact, the former place, now a thriving city, owes practically its whole importance to the quarrying of this stone.' Vermont granites vary in color, from light to dark gray and range in texture from coarse to very fine.^ The granite of Barre, is of the l)est quality known, and is used to a ver}- large extent for momunents and tine; decorative work, because it takes a tine polish, and stands exposure to weather without apparent injury.' The stone occurs in thick strata, and can be taken out in immense blocks which adds greatly to its value as a structural material.* In 1902 Vermont ranked third among the granite pro- ducing states with a product valued at $1,. 570,423. or 26. 6 per cent of mineral output of the state, and 8.6 per cent of total value of product of the industry in this country. The value of the granite, Vjoth rough and dressed, that was used for monumental purposes, amounted to $1,209,194, or 77 per cent of the state's production, while the value of that used for all other purposes amounted to 1361,229, or 23 per cent. Slate. — Although slate is found in a majority of the counties of the state, there are three distinct belts trav- ersing the eastern, middle, and western parts of the state. Of these, the western belt, especially that section lying in Rutland county, is by far the most important, and it is here that the well-known quarries at Castleton, Fair Haven, Poultne}', Wells, and Pawlet are located.^ The first slate quai-ry in Vermont is said to have been opened in 1805," although the year 1839 is usually consid- ered to be the date of the beginning of the industry in the state. It was, however, not until 184.5 that the quarry- ing of this stone began to assume the proportions of an important branch of the mineral industry of the state.' In Vermont slate is found in many colors, the most common of which are green, purple, black, red, and chocolate, with the variegated or mottled varieties,' a single quarry not infrequently producing several differ- ent colors of stone. Of the green shades, there are two classes known as "sea green" and "unfading green," both being used extensively for roofing purposes, the unfading green retaining its color permanently, while the sea green, upon exposure to weather, turns to a yellowish brown.

The (juarries are all open pits, ranging in depth to as much as 300 feet. The quarry hig of slate is attended by an enormous waste of material, not more than one- sixth of the total quantity of rock removed being avail- able for use, and the dump piles grow with such rapidity and to such size as to become a serious hindrance to the progress of the work." Tite state's product of slate in 1902 amounted in value to $1,464,918, or 24.8 per cent of the total value of its out- put of all minerals. Of this amount, 91.4 per cent was used for roofing purposes. Vermont ranked second among the states in 1902 in the production of slate, and the output was valued at 25.7 per cent of the total yield of the country. It was put to the usual uses, including roofing, school slates, beds for billiard tables, etc. Large (piantities of domestic slate are exported and the demand increases steadily.'"

In 1902 a production was reported by two establishments located in Benning- ton county. An iron ore mine located near Brandon, Rutland count}', reported a small production for 1902. The ore Tias also been found at Monkton, Bennington, and other localities, mostly in the southern part of the state." It usually occurs in the form of ))og ore and limonite, and was first discovered at Brandon in 181(>, soon after which a forge and furnace were erected there. In the same vicinity ocher has been discovered.'^ In 19(»2 small amounts of ochei-, iron, and metallic substances were extracted in Rutland county and, being ground for jjaints, were classified as crude mineral pig- ments. Aside from the small value they added to the total mineral output of Vermont, these ser\e chieHv to show the diversity of Rutland comity's mineral wealth. There was one quarry in Orleans county from which a production of oilstones, whetstones, and scvthestones was reported in 1902.

The range of mineral industiy in Virginia in 19U2 was wide and varied, comprising within its scope the production on a conimercial scale of twenty-four differ- ent minerals. First among these in point of value was the production of bituminous coal, obtained in the main from the vast deposits of high-grade steam and coking- coal in the southwestern part of the state. It is this region that furnishes the celebrated Pocahontas coal. Iron ore, which was extensively produced in 1902, oc- curs among- the mountains in deposits of remarkable richness, the beds of ore being from 20 to 100 feet in thickness and many miles long. For 300 miles the western foothills of the Blue Ridge are lined with brown hematite ore and solid masses of it appear along the AUeghenies.^ The yield of brown hematite from this region comprises an important percentage of the total output of this variety in the country, and also consti- tutes the bulk of iron ore production in the state. The industry of manganese ore mining had its begin- ning in Virginia, and more than one-half of the total output of this mineral in the United States has been contributed bj^ the mines of this state, during the third of a century of manganese ore exploitation in the country. The lead and zinc deposits of Wythe county have been worked for more than a hundred and twenty-five years, and furnished lead co lioth the Continental and Confederate Armies. - 'King's Handbook of the United State.o, page 8.58. '■'Transactions of the American Institute of Mining Engineers, Vol. V, page 8.5. The great gold belt, 200 miles in length, which stretches from the Potomac to the Dan, has furnished more than 12,000.000 worth of gold to the Mint.' The copper deposits of the state are extensive, espe- cialh' in southwestern Virginia,' and the noted depo.sits of Louisa countv have long- been the seat of an impor- tant industry.' The sandstones of the Blue Ridge, the limestones and slates of the valleys, and the granites which are widely distributed afford an abundant supph* of building ma- terials, and their exploitation constitutes an important industry in the .state.' From the feitilizing- marls and greensands of Tide- water westward to the vast coal and metalliferous de- posits near the Kentucky and West Virginia lines is spread a great varietj' of mineral wealth, which affords such basis as to make the mining- industry an important factor in the industrial activity of the state. The following is a list of minerals of known occur- rence in Virginia which were not produced commer- cially in 1902: Allanite, alum, arsenic, bismuth, car- bonite, feldspar, fire clay, kaolin, marble, plumliago, quartz, serpentine, and tin. Work of a developing character, where no produc- tion was realized from the mining properties, was re- ported by b operators, and was confined during 19(i2 to gold and silver and manganese ore.

The relative importance of manufacturing industries closel}^ allied to or based upon the mining industr_y, using as their raw material the products of mines and quarries, is shown in the following table: Table 2. — Manufactures based primarily upon the products of mhus and quarries: 1900.

During the same year there were employed in all branches of manufacture in the state 72,702 wage-earners, who were paid $22,445,720 in wages. In 1902 there were employed in the mines and quarries of the state 8,993 wage-earners, who received $3,458,450 in wages. Com- paring the figures for these two branches of industry, it will be seen that 89 per cent of the wage-earners, receiving 86.6 per cent of the wages, were employed in manufacturing, while 11 per cent of the wage- earn-ers, receiving 13.4 per cent of the wages, were employed in mining.

From the beginning of the industry of coal mining until 1789 the entire output went to supply the local demand. During 1789 the product of the mines began to find a wider market in the northern cities, and for many years the bituminous coal deposits of the Richmond basin were the only source from which this mineral could be procured and shipped coa.stwise.' The product sent out in this way to other cities had grown in 1822 to 48,000 tons and in 1833 to 143,000 tons.' About this time the discovery and development of other coal areas carrying deposits of superior quality and more economical of exploitation caused a rapid decline in the output of this region. By the middle of the century the production of coal in this field had practi- cally ceased. For more than a quarter of a century the output of coal in the .state was insignificant, but the building of the Norfolk and Western Railway, in 1883, was followed by the development of the great coal deposits of southwestern Virginia, notably the Poca- hontas region, and the state soon came again into prominence as a coal producer. In 1880 the total coal production of the state was only 112,000 short tons, but in 1889, or seven j^ears after operations in the new fields were under way, the output had increased to 865,786 short tons, and in 1902 had reached a total of 3,182,993 short tons.

The record of this first exploitation of American ore by Europeans states that this ore was smelted and 17 tons of metal were sold at &\: per ton.^ For several years following numero'us attempts were made bj- the Virginia Companj- to establish the indus- try of iron manufacture in the vicinity of Falling creek. Under the direction of John Berkley, who was sent out by the company in 1621, the construction of several plants for the reduction of the ore was begun. How- ever, just when these works were nearing completion and the prospects for a rapid development of the industry were bright, the colony was massacred by the Indians, ■on March 22, 1622. There is no record of further ef- forts to manufacture iron in the colonj^ for many j^ears. In 1687 and again in 1696 Col. AVilliam Byrd set on foot a plan to rebuild these works, but the project never materialized.* In the eighteenth century, however, the colony be- came very prominent in the manufacture of iron and fulfilled in an eminent degree, though at a much later •day, the expec'tations which had been entertained of its iron producing capa))ilities bj- the enterprising but unfortimate Virginia Company of Ijondon.* To Col. Alexander Spotswood, who was governor of the colony from 1710 to 172-3, has been accredited the honor of establishing th(> iron industry of the state on a firm and permanent basis. During this period a col- ony of German Protestants settled at the head of the Rappahannock ris'er, with the hope of locating mines. It is probable that the first furnace in the state was owned by Governor Spotswood and was built and oper- ated in 1715 or 1716 by these Gerinan miners, who were in his employ." ■ The industrv of iron making, tlie growth of which was stimulated by encouragement from the colonial go\'- 'Coal Statistics, pu))lished ))y Aliler & Ruley, 1902, page ItU.

In the production of pyrite, the importance of which is rapidl\' increasing, Virginia took first rank in 1902, with an output valued at $501,642, oi- 6-4.7 per cent of the total 3'ield of this mineral in the United States. Cement. — The industry of the manufacture of cement from natural rock in Virginia dates from 1835 and had its beginning in Rockbridge county. The (juality of this tirst product was excellent. Works were established at Balcony Falls in 1848; subsequently this plant was destroyed by flood and later was rebuilt on a more extended scale at Locker, a short distance away, where it is at present in operation and enjoys the dis- tinction of being the oldest active cement plant in the state. Another large and important cement plant is located near Staunton, at Craigsville. It was built in 1900, and in 1902 contributed an important percentage of high-grade cement to the total output of this mineral in the state.'' Table 6, compiled from the reports of the United States Geological Survey, shows the annual production of cement from 1890 to 1902. Table 6. — Annual production of cement: 1890 to 1902.

Siliceous cryHtalline ivcI'k. — The production of build- ing stone has long been an important industry in the state, and the output of the Virginia granite (juarries has been used in many notable structures. Among these is the State, War, and Navy Department liuild- ing at W^ashington.' The siliceous crystalline rocks of the state aic con- tined in the main to a belt or zone running from Alex- andria count}' through Fairfax, Fauquier, Spottsvlva- nia, Henrico, Goochland, Chesterfield, Dinwiddie, and Greenesville counties, into North Carolina. While a wide area of occurrence is comprised within this Ixdt, the outcrops of (juarriable granite are confined to a \ery limited part of this region, the principal points being in Chesterfield and Dinwiddie counties, on the James river, and in the immediate vicinity of Richmond.

The product of the (|uarries in the vicinity of Rich- mond and of those in Chesterfield county is a massi\-e gray granite, well adapted for general building purposes, paving stone, and monumental work. This granite has found a market in practically all the states and cities south of New England and as far west as Nebraska.-' SIdfe. — The occurrences of slate in deposits of com- mercial importance are distributed over a considerable area in Virginia and have been exploited in numerous places. The principal producing district in 1902, and that within which the industry of slate quarrying in the state most probabh' had its origin, was in Bucking- ham county.' Smallei- products were also reported from Amherst and Albemarle counties. Abundant de- posits of this mineral have been found and developed to a limited extent in the Great Valley and Appalachian districts.' Mangditese arc — The beginning of manganese ore mining in Virginia, and perhaps in the United States, occurred in 1857 in the Shenandoah valley, about lOO tons being taken out during that year. In 1868 and 1869 about 5.000 tons of manganese ore were taken out near \^'armillster, and this marks the beginning of sys- tematic manganese ore mining in the state." For many years the states of Virginia and Georgia have contributed the bulk of the output of this valuable mineral in the United States, nearly all the yield being exported to England. The period of greatest activitv in manganese mining in the state was that beginning in 1885 and clcjsing with 1891, during which years the average annual production was about 15,0oo tons, the maximum output occurring in 1886, when the total was 20,567 long tons. There has been a marked decline in the state's production in recent years. Table 7, compiled from reports of the United States Geological Survey, shows the annual production of manganese oi-e in the state from 18S0 to 1902. inclusive, during which period the state contributed more than 55 per cent of the total output of this mineral in the counti-y.

VIPtGINIA, 333 The known occurrences of munganese ore in the stati' are widel}- distributed, being practicall}' coextensive with its area. Beginning' with the pocket occurrences in the eastern part or Tidewater district, manganese ore has been found and mined in the Midland, Pied- mont, Bhie Kidge, Valley, Appalachia, and trans- Appalachia divisions westward to the West Virginia line. The great bulk of the state's output, however, has come from the Vallej' region.' All other minerals. — Asbestos, which occurs in nu- merous places in western and southwestern Virginia,^ was mined to a limited extent during the year. Barytes of good quality and in large quantities occurs at many points in the southern and southwestern parts of the state, notably in Campbell county- in the vicinity of Lynchburg,' and its mining has for manj^ years been of relative importance. The output of this mineral in Virginia in 1902 comprised more than one-fifth of the total production in the country. Buhrstones and millstones were obtained from granitic rocks at several places in the state, the production for 1902 constituting nearly 20 per cent of the total value of production of the United States. Copper ores occur extensively in southwestern Vir- ginia and in some other sections of the state, espe- cially in Louisa county near Talersyille.* Copper was produced on a commercial scale in 1902 at only one mine. Virginia became a producer of flint in 1902, though the output was small and was confined to one mine. Gold and silver in a limited wa}^ has been a mineral product of the state for more than a century and a quar- ter. The first recorded discovery of gold in the state was that noted in the papers of Thomas Jefferson. About 4 miles below the falls on the Rappahannock river there was found a lump of ore weighing 4 pounds ; this jnelded, when treated, 17 pennyweights of gold." Gold is of wide occurrence in the state, and extensive mining operations have been prosecuted at different times over a wide area. The principal deposits occur within the Virginia gold belt, which extends from the Potomac 'United States Geological Survey, "Mineral Resources of the United States," 1892, page 202 ff. 2 Ibid., 1882, page 738.

Gypsum, the producing localities f)f which are the Holstoii I'iver fields around Siilt\ille, was mined in 1902 to a limited extent at two points, though in former years large ([uantities of this mineral were taken out.' An extensive bed of infusorial earth is traceable from the Patuxent river in Maryland to the Meherrin in Virginia. Exposed patches occur at Richmond and other points." The output in 1902 was limited to the production of two concerns. A small quantity of lead ore was produced in 1902 at two mines, the work being carried on in connection with the mining of iron ore. Extensive deposits of lead ore occur in southwestern Virginia, and lead min- ing was begun in this region more than a century ago." The marls which occur in the eastern part of the state were mined to a limited extent during the year, one establishment reporting production. Virginia and New Jersey mined the entire production of marl in the United States in 1902. Mica occurs in numerous places, notably in Hanover, Goochland, Bedford, Henry, and Amelia counties." The production in 1902 was from two mines. Mineral paints were produced to a limited extent during the year in Bedford and Page counties. While no mining operations were prosecuted for precious stones, specimens of value were picked up in a nimiber of places. Deposits of rutile occur on both sides of the Tj^e river near Roseland post office, in Nelson county, and the pro- duction of this mineral during the year was confined to the output of one company operating in this vicinitj'. Sandstones and quartzites were quarried during the year on a commercial scale at two points. The occur- rence of these rocks in the state is extensive.' Numerous occurrences of soapstone have been noted in the state, notably in the southern and southwestern parts. In Campbell county there is a continuous belt traceable for miles.'" The product of the state in 1902 was reported from two mines. •■ United States Geological Survey, "Mineral Resources of the United States," 1887, page 800.

The large, mountainous area aliounds in rich deposits of useful and precious minerals awaiting only the fur- ther progress of developaient operations and improx-ed transportation facilities to become valuable workings. The coal fields have thus far received the greatest atten- tion, the product of coalmines in 19(.)2 amounting to 84.7 per cent of the total mineral production in the state. There was no production, on a commercial scale, of iron ores in iyn:i, although deposits of consideral)le extent are known to occur in the state. The iron ores found in Washington are magnetites, hematites, limon- ites, and mixtures of hematite and magnetite, and the localities of principal occurrence are in Skagit, King, Kittitas. Stevens, and Mason counties, while bog ore is found in Whatcom, Clallam, Spokane, Whitman, Thurston, and Jefl'erson counties." Galena is about the onl_y lead ore found in the state and it occurs chiefly in association with other sulphides, as does also zinc, wdiich is found in small (juantities in the form of sphalerite or zinc-blende."

(«34) One hundred and tifty-one operators in the state of Washington reported a total expenditure of §l,()i!::!,.3'»7 for development without production during 1902. This amount includes salaries and wages, miscellaneous ex- penses, cost of supplies and materials, and contract work, and represents an outlay greater than one-hfth of the total expenditures reported by the 9<> producing mines and ciuarries in the state. Of the 151 mines reporting development work, 143 were gold and silver mines with expenses amounting to §989,812, or 9(;.s per cent of the total disbursements for this purpose. Mineral products form a basis foi' manufacturing industries to a large extent, being used as raw or par- tially manufactured material.

The total mine and quarry production during- 1902 was valued at $5,393,659, or 5.8 per cent of the com- bined products of manufactures in 1900 and mines and quarries in 1902. During- 1900 there were employed in all branches of manufactures in the state 33,806 wage-earners who were paid $19,106,873 in wages. In 1902 there were employed in the mines and quarries of the state 4,567 wage-earners who received $3, 735, -ixl in wages. (lom- Ijaring the figures for these two branches of industry, it is seen that 88.1 per cent of the wage-earners, receiv- ing- 83.6 per cent of the wages, were employed in manufactui-ing establishments, while 11.9 per cent of the wage-earners, recei\ing 16.4 percent of the wages, were employed in the mines and quarries of the state.

With the construction of railways into mining- and quarrying districts, more extensive development of the mineral resources of the state should speedily follow. Metalliferous deposits occur in many parts of the state,' the sulphide ores appearing in greatest abundance. Arsenides and anti- monites are also found, but oxides and carbonates are somewhat less plentiful. The value of the nonmetallic mineral product during- 19u2 greath- exceeded that of the metallic, because of the extensive operations in coal mining and stone quarrying. Coal, hitumnious. — The first discovery of coal ■ was in the Cowlitz valle}^ during 1 848, but the quality was inferior. The occurrence of coal on the Stilaguamish river" was known as early as 1851, and deposits near Bellingham ba_y were discovered in 1852. In the fol- lowing year the Sehome coal deposit, and that on the Black river not far from Seattle, were opened. In 1863 coal was discovered at (iilman and also near Lake ^Yash- ington, and at a later date the Green river and other coal fields were found. The character of the coal produced is chiefly lignite, although it often ranges to a bituminous or a semi- bituminous variet}^ Washington is the only one of the Pacific states in which coal of a coking quality has been mined, all the coal produced thus far in California and Oregon having- been lignite. The principal coal fields of the state are located in Kittitas, King, Pierce, Skagit. Whatcom, and Lewis counties in the order named, and important outcrop- pings have lieen ni)ted in Lincoln, Spokane, Thurston, and other counties. The production increased Y_)henom- enally from 145,015 short tons, valued at $389,046, in 1880, to 1,263,689 short tons, with a value of $3,426,,590, in 1890, an increase of 771.4 per cent in the quantity and 780.8 per cent in value. During the jjeriod of twelve years from 1890 to 1902 the increase in (juantity was 112.2 per cent, and in value 33.4 per cent. In 1902 the state ranked fifteenth in the United States in coal production, the total value of the product reported in that vear being over S4,50le.—"^\iB marble quarried in Washington is of a serpentinous character, and is found principalh' in the eastern part of the state in Adams and Stevens counties. It is necessarily extracted in small blocks on account of its seamed markings. The production in 1902 was largely utilized for building purposes and interior decorations. There was a large increase in the production of 1902 over former years, especially in the output of rough and building marble. fiatid'itones and quartzites. — The principal occur- rences of sandstones in Washington are found in the extreme northwestern part of the state in San Juan and Whatcom counties, and the production has de- creased materially as compared with previous years. All other minerals. — Clay deposits occurring chietiy as glacial clays, residual clays, and clay shales are found, and a small production was reported from the north- eastern part of the state, but no extensive mining of these was done during the year. The prevailing mineralogical character of the copper ore mined in this state is copper glance passing into chalcopyrite, and it is found in fissure veins with gran- ite. The state's production in 1902 was confined to the output of one establishment. The utilization of molybdenum in the preparation of steel has caused an increased demand for this mineral. It is also used in the manufacture of chemical reao-ents, principally ammonium molybdatc. and in the prepara- tion of "blue carmine" for porcelain coloring.' The molybdenite in this state occurs in association with gold, silver, and copper ore. and all the production was reported by one company.

The extensive coal deposits in the state are almost inexhaustible, coal being found in all but three coun- ties, and the annual production has steadily increased until in 1902 West Virginia ranked fourth among the coal producing states. The oil production is large and the state has within its borders the largest single pro- ducing oil field in the world. Natural gas wells are numerous and productive. Most excellent building stones abound throughout the state, and the white sand near Berkeley Springs, in Morgan county, is of excep- tional puritj'.

In all but 4 of the 55 counties of the sttite bi- tuminous coal has been found.' The advantages of the state in coal production lie in the facts that a great number of the seams found arc ac- cessible above water level, and that the coals are of vai'i- ous compositions adapted to the requirements of trade. The fat coking, gass}' bituminous, the hard and \al lia- ble splint, and the rich and oily cannel coal are found in great purity and made easily accessible through the agency of running water, which has exposed the seams in thousands of places. This fact, added to their size, permits, as a general rule, the mining of coal in West Virginia to be carried on at less cost, and witli more economy, under con-esponding labor rates, tiiaii is pos- sible in any other part of the Allegheny coal Helds.'

The presence of coal in West Virginia was known to the earliest settlers, and shipments were made f i-om the Cumberland-Piedmont district of Maryland and West Virginia as early as 1842, but until 1855 all the ship- ments were from Maryland.'' In 1863 a few small coal mines produced some coal for domestic consumption," and in 1864 the lir.st splint coal was mined at Coalburg, in Kanawha county-' During the past twenty-three years the increase in the coal production of West Vir- ginia has averaged 1,()()0,0()0 tons a year. The principtil coal producing regions of the state may be divided into four districts, which include the more important coal producing counties. These during 1902 produced nearly 90 per cent of the output of the state. The two northern districts are known as the Fairmont, or Upper ^lonongahela district, and the YAk Garden, or Upper Potomac district. The two southern districts are the Pocahontas, or Flat Top district, and the New and Kanawha river district. The most important dis- trict from the productive point of view is the New and Kiiiiawha river district, which includes the counties of Fayette. Kanawha. Raleigh, and Putnani." In 19()2 coal was mined in 29 counties, among which McDowell ranked Krst with ;i production of 5,459,655 tons, Fayette second with 4,775,112 tons, and [Marion third with 3,397,194 tons. The total production in 1902 w'as 24,57(1,826 tons, an increase of 502,424 tons over 1901. The greatest increase was shown in McDowell county. Fayette county showed a decrease of 1,277,277 tons, due to the strikes in 1902.

In 1902 West Virginia ranked third among the states in the production of natural gas. Large areas in Lewis, Harrison, Marion, Monongalia, and V^^'etzel counties were discovered and developed between 1900 and 1902. More or le.ss natural gas has been developed in Tjder, Ritchie, Doddridge, Marshall, Wood, Wirt, Roane, Cal- houn, Boone, Mingo, Kanawha, Logan, and Gilmer counties." Since 1895 there has been a notable yearly increase in production of natural gas. In 1902 the value of the production was §5,390,181, an increase of 11,435,709, oi- 36.3 per cent as compared with 1901.

Jefferson county ranked first among the 11 coun- ties in value of product, but Preston county ranked first in number of quarries. The value of the blast furnace flux produced in the state in 1902 was $268,059, or 43.5 per cent of the value of all limestone.

In Monongalia [ county a beautiful sandstone, of a light l)utf and dove color, is found which can be dressed readilv, and is most suitable for building purposes. In Taylor county occurs the so-called Grafton sandstone of close texture, sharp and clean grit, and gray color. The gray sand- stone of Lewis county has few. if any, superiors in the United States in architectural beauty. The sandstones of the Lower Coal Measures on the upper portion of the Kanawha river have furnished materials ft)r locks and dams built by the Government.'' Only 10 of the 110 quarries productive in 19(i2 had an output valued at more than $10,00(1.

Stratified beds of clay, from which over .50,000,000 bi'ick are made aimually, are found along the shore of Lake Michigan. Although the clay usually is red the bricks are cream coloi'ed, and Milwaukee derives its name of "The Cream City" from the fact that this brick has been used so extensively in its buildings.^ The value of the clay produced in Wisconsin in 1902 was 123,178, and the value of the brick and tile made from it was |1,011,373.' There are copper ores in the zinc and lead district of southwestern Wisconsin, and some crude attempts at copper mining have been made. By far tlie most im- portant recent development, however, has been in Douglas county, in the northern part of the state.' Some graphite was produced in Portage county in 19o2, and some metallic paints were made from a cer- tain hematite iron ore found in Dodge count}-, but no figures can be shown for either of these minerals with- out disclosing individual operations.

Although greatly hindered in tlie development of its mines and quari-ies because of the lack of capital and means of transporta- tion, its product in 1902 was valued at $.5,684,28B. In the value of its mineral pioducts the state was twenty- seventh in rank; almost the entire mineral pioduction was from its mines of coal, in the output of which mineral the state ranked fourteenth. The rocks included in the group "sandstones and quartzites," occur in almost inexhaustible beds, and are equal to those of any othei- state in point of beauty and durability.' Limestones and dolomit(.'s are of wide occurrence and were quarried to a limited extent in l!t02. Gold and silver mining, which was an important fac- tor in the early development of the state, has decreased in importance, until in 1902 the product amountctl to only $1,923.

The first mine was opened at a point about 3 miles from Evans- ton, in Uinta county, soon after the construction of the transcontinental railway. The coal fields of Wyoming cover an area of more than 20,000 square miles; thej^ have been known since 1850, but remained undeveloped until 1868 because of the lack of transportation facilities and market." Since that time coal mining has developed into the leading branch of mineral industiy in the state, and the known area of coal deposits has been extended through succes- sive discoveries until it includes every county in the state; some of the veins vary in thickness up to 75 feet. The most common variety is a pure lignite, though in certain localities a good coking coal is mined. In 1887 a semianthracite coal was discovered in Johnson county.' The best grades are low in ash and sulphur, and are excellent for steam making, domestic purposes, and the manufacture of gas. During the early develop- ment of the industry, almost the entire product was sold to the railway companies,* but in later years their consumption has amounted approximately to one-third of the production.'"'

Veins of graphite occur at French creek. Plumbago canyon, and Halleck canyon in Albany county, and in the Indian Grove mountains in Carbon county. The veins are large and easily accessible and contain from 40 to 60 per cent of carbon.* The Triassic formation exposed along the eastern side of the Laramie plains contains a large percentage of gypsum, one stratum near the bottom of the forma- tion being of considerable thickness. The Laramie bed. known localh' as a deposit of gypsite, has an average depth of 9 feet, and the mineral needs only to be cal- cined to prepare it for the market. The manufacture of plaster of Paris and stucco has been carried on at Ked Buttes since 1889. '■ The occurrence of iron ore has been known for some time at a point '2\ miles north of Rawlins station. Two mines were opened here in 1871 and worked until 1877. Since that time only a few tons have been mined in this region and these have l)een used for the manufacture of mineral paints."

REPORTS ON SEPARATE MINERALS IRON ORE (393) IRON ORE. By John Birkinbine. The statistics which are given in this report refer solely to the irou ore mines located in the I'nited States, excluding- the insular possessions and Alaska; they show that in the year l!>()2, 35,567,410 long tons of iron ore were mined in the United States, 25 states and ter- ritories contributing to malte this total. This includes 13,275 tons of special manganiferous iron ores obtained in Colorado. These ores were included Ijecause the labor and wages expended on them could not be segre- gated from those expended on the iron ores proper. The amount of true iron ore produced was 35,554,135 long tons. The statistics included in this report do not show fully comparative data for the various census years because the inquiries at the different census periods were not identical. However, such as are shown will aid in a study of past and existing conditions. Prior to 1880, the number of iron ore luines grew with the pig iron industry, individual ))last furnaces depending largely upon mines which were adjacent to the plant or controlled by the same owners. Subse- quently, as blast furnaces were enlarged requiring greater amounts of iron ore, it became necessary that several mines should be combined under the same man- agement, or that existing mines should be exploited to a more liberal extent than before. In Table 1 the statistics for each of the census years 1902, 1889, and 1880 are presented, but a resume of the data, so far as it could be collated, for 1850, 1860, and 1870 is given, as follows; In 1850 the "number of estab- lishments" was 197; the wage-earners were 2,195, re- ceiving a total of $590,866 in wages; the cost of supplies and materials was $63,651, and the value of the product of the regular mining establishments to which these data refer was $1,217,803; but the amount of iron ore smelted was given as l,579,3o9 long tons. In 1860 the total amount of iron ore mined from 157 regular mining establishments was 908,300 short tons, or 810,982 long tons. These establishments gave em- ployment to 3,177 persons, to whom $901,852 was paid in wages, and 1249,699 was the cost of raw material. In addition, many of the large iron works of the coun- try mined their own ore, the quantity thus raised amounting to 2,309,975 short tons, making the total quantity 3,218,275 short tons, or 2,873,460 long tons. While the short ton was not designated as the unit of measure in 1860 or 1870, it was reported in 1880 and presumablj' was used at prior censuses. In 1870 there were 420 regular mining establish- ments, employing 15,022 wage-earners, who received as compensation $6,838,022. The cost of supplies and materials was $1,279,563. The product was 3,395,718 short tons, equivalent to 3,031,891 long tons, valued at $13,204,138. This production does not include the amount raised, between 800,000 and 900,(M»0 tons, by some of the blast furnace operators, so that at a low estimate the production of 1870 reached a total of at least 3,831,891 long tons. The incjuiries for the census j'ears 1902, 1889, and 1880 were more nearly identical than any of the others, and therefore a comparison of these gives results of greater immediate A-alue. The statistics for these peri- ods are summarized in the following table: Table 1. — Comparative summanj: ISSO to 1902. 1889 Number of mince Number of operators Salaried officials, clerks, etc.: Number Salaries Wage-earners: Average number Wages Contract work Miscellaneou.s expenses Cost of supplies and materials .

The number of mines in 1902 shows an apparent decrease of 67 since 1889. which was caused in part by a difference in the methods followed at the two censuses. In the year 1889 all iron mines were included which were doing exploratory worlc. In the statistics for 1902, however, only the mines which contributed iron ore are included, 257 which were being prospected, (395) 39r. MINES AND QUARRIES. or in which sliafts wore hcing sunl<;, or wiiich were temporarily idle, being excluded. There have been nume'rous consolidations of important mines, thus re- ducing- still further the number reported in lltoi. Iti many instances two or three mines which were formerly operated inde])endently have been united, connected witli common shafts or slopes, and the ore usually all mined under one management. Thus, the C'hapin mine, on the ]\Ienominee range in Michigan, combines what were formerly known as th(^ Chapin, Ludington, and Hamilton mines; the Nori'ie mine, on the Gogebic range in ^Michigan, embraces the North Norrie, East Norrie, Norrie, and Pal)st; and the Gary mine, on the same range in Wisconsin, represents the Gary, ^^'est Garv, and Odanah nnnes. Other similar consolidations in the Lake Superior and Southern districts could be mentioned. In the 18S0 census the nundier of establishments was reported as 805; this included a number of small opera- tions, especially in the eastern section of the United States, wdiich were afterwards abandont'd because im- proved transportation facilities permitted the utiliza- tion of the richer ores of the Lake Superior district where operations on a large scale were possible. The number of wage-earners and salaried otticials was 38,227 in 1889 and 41,256 in 1902, but the compensa- tion paid them increased from $l-t,109,151 in 1889 to $23,61:5,022 in 1902. It would appear, therefore, that the proportionate increase in the amount paid was much greater than in the number employed. This is due, in part, to the difierent methods used in the calculation of the average number of men employed. In 1902 the number of employees in active min(\s only were consid- ered, and the average number employed during the vcar was reduced to correspond with the number which would be required at •"continuous employment for twelve months to produce the (piantity of product reported.'" Thus, if 200 men -svere employed at an open cut mine which, owing to climatic conditions, could be operated for only nine months during the year, the average num- ber for the entire year, its detei-mined in 1902, would be 150 instead of 2n(i. The proportionate increase in the amount paid, therefore, is not so much greater than that in the number of employees as it might se(»m from the statistics. Moreover, in the ix.s'.t census all of the persons em- ployed at mines wdiich were active, or nngiit again be- come active, were included. If to the number given for 1902 in Table 1 those employed in the exploitation of mines not yet shipping ore and in mines temporarily idle be added, the total number of persons- employed woidd be increased from 41,256 to 41,551, and the wages from $23,645,022 to $23,822,339. In addition, in 1902, 1,365 men were employed by contractors in acti\'e irnn(w and in de\-elopme]it work, the contractors recei\'ing $641,460. In the year 1889 the cost of supplies and materials was $4,99.S,!(88, the amount paid in wages and salaries was $14,409,151, contract work cost $1,578,010, and mis- cellaneous expenses $3,795,509, a total of $24,781,658. In the year 1902 the total wages and salaries were $23,645,022, contract work cost $425,292, supplies and materials $9,0o5,6OS, miscellaneous expenses were $8,257,714, a, total (^f $41,333,636.^ Table 1 indicates that in 1902 the quantity of ore mined was about five times the product in 1880, but that the value of the ore produced in 19(12 was less than three times that of 1S80. The total value at the mines of the 35,567,41(J long tons of iron oi-e produt-cd during the year 1902 was $(i5,465,321, an average of $1.^4 per ton. The value of the 14,518,041 long tons produced in the year 1889 was $33,351,978, (jr $2.30 per ton. This shows an increase in quantity of 21,049,369 long tons anrl in value of $32,113,343. liecause of the greater use of lal)or- saving appliances, and other economies, resulting in piirt from the consolidation of contiguous mines, the average value per ton shows a reduction of 4ti cents, or 20 per cent. In the following statement the average value at the mine per ton of iron ore is presented for the census years from lS(i(.) to 1902, inclusive. The figures for the regular mining establishments are taken fur the earlier years, as the diflference in total amount would make little change in the average \alue per ton of product. CENSUS VEAH.

IStiO S-J. 69 4.3.5 3. 2.T 2. ?M 1.S4 ISTO lyO'2 -- In th(^ earliei- census yetirs the mines were nearer the furnaces, while in the Ititer the ore was carried lono- distances to points of consumption. This explains, in part, the higher value at the mines in former years. T)i'Vi'li)piHiiii mirl-. — In conn(>ction with minin"- a certain tunount of preparatory or explorsdory work is always required. In most of the producing mines the labor, co.st of supplies and materials, and miscellaneous expenses incidental to such work are charged to the i-egular opertiting expenses and do not appear separatelv in the reports. There are, however, in addition, a number of mines which are mere explorations or developments, not having produced any ore, or old nunes wddch, having been abandoned, have l)een r(M)pened. It is dithcult to olitain accurate^ informa- tion in regard to the expenditures for WK)rk dou(> pre- paratory to the actual shipping of the ore, espt-ciallv where acom])any has not been organized, but such data ' 1902 lifjiues are exeUisive of lieveloptnent work.

Table 2 shows that there were oT nonproductive mines engaged in development work in the United States in 1902, employing 28 salaried officials and an average of 2fiT wage-earners, who received 1177,317; the cost of supplies and materials being $113,541 and the miscel- laneous expenses $68,533. These mines were capitalized at $2,(!S5.000. "While these figures do not represent the full amount of expenditures for this class of work during 1!M)l>. they give some idea of the exjjense necesstiry bef(.)re mines become producti\-e. The most active exploitation of new clei)osits was in the states of Minnesota and Midi- igan. In most of the older ,states. such as New .lerscv and New York, little exploratory work was done, except by acti\-e companies: such work was included in the reports of the tictive mining operations of these comjianies. In addition to the mines included in the above table, there were 220 mines which ajipear to have been en- tirely inactive during 1902 as regards i^roduction or development work, no expenses for siuli work having been reported. The mines classed as idle should not be considered ;is including abandoned mines or openings which have been idle for a long time with no efl'ort made to revi\e them, nor do they include mines which have been dis- mantled. The purpose was to add to the record statistics covering such mines or operations as ma_y be producers in the near futui'e. t'ltjiifal sfocl: II f / iicDi'pin'dfi'il (■(HiiptmicK. — It is diffi- cult to arri^•e at a fair determination of the proportion of capital stock and bonds properly chargi^tible against iron ore mines when operated by corporations owning blast furnaces and rolling mills, coal mines, railroads, etc., or by companies subordinate to parent organiza- tions, or where the mining property is leased. Thus, A leases an iron ore property to B, who for this lease pays either a definite sum or, more often, a fixed or slid- ing scale royalty per ton foi' the ore taken out foi- a gi\-en [ time. Usually a minimiim annual output l)eing stipu- j lated. The operations may he ui)on a small part of the propeity owned by A, liut if A places a value upon it, this \alue would probably include the entire tract. B can tix no value for the ii'on ore property, being mcrelv a lessee, and would probably base his \-aluation upon the royalty he pays capitalized, which will be constantly changing as the mines are worked energetically or other- wise, or as the demand ftjr oi-e is active or slack. The ownei' or the lessee may or may not be interested in the manufacture of iron. There tire cases whert.' the mines of an iron pi-oducing company are worked under lease for the advantiige of another company, because of the location of the deposit as i-elated to the works of the owner or the lessee. In some instances compiini(\s organized vears ago with moderate capital own or control large mines lease and not of the land. In addition to earnino-.s on the capital stock of the company a fixed or, in some cases, a sliding royalty is paid, which, in the latter case, is based upon the market price of the ore; this royalty value is not recognized in the capitalization. 398 MINES AND QUARRIES.

In the year 1.S89 returns were secured from the .592 dili'erent mines of the value of the land, Ijuildings and fixtures, tools and implements, and the amount of cash and stock on hand, showing a total of $109,766,199.

The.se statistics show practicalljr .steadj- employment in such states as Alabama, Georgia, Tennessee, and Virginia, where the climatic conditions do not interfere with mining operations; and even in the states of Min- nesota, Michigan, and Wisconsin, the variation in the number employed was less than generally presumed to be the case. This was undoubtedly due to the fact that the demand for ore encouraged a considerable amount of "dead work" and underground exploitation during the winter months. It is probable that figures for the 3^ear 19().3 would show considerably greater variation between the seasons than those for 1902. While the states of Minnesota and Michigan pro- duced 76.7 per cent of the iron ore mined in the United States in 1902, the average number of wage-earners in those states represented onlj' .58.5 per cent of the total for the country', and a calculation shows that for each wage-earner in those states 1,156 tons of iron ore were produced.

It should be pointed out, in eonnection with the fore- going table, that the increase in 1!>02 over IS.Si* in the productive capacity per wage-earner is probably con- siderably less than is indicated l)y tlie figures, owing to the difference in the method of computing the average number of wage-earners at the two censuses. An analysis of the statistics oi wage-earners presents some interesting features. In Table l-i, showing the detailed statistics, it will be noted that out of a total of 38,851 wage-earners, 23,(i8'i are reported as employed below ground. That is, of the total iuunl)er of wage- earners engaged in the iron ore industry 5y.4 per cent are employed below the surface, the remainder being- engaged upon surface mining oi' upon the work above ground. It is also shown that out of a total of 38,851, those returned as miners and miners' helpers, number 20,849, which suggests that sliglitly over one-half of those engaged in the iron ore industry may lie consid- ered as actually digging the ore. As already stated, exact comparisons between the num- ber of wage-earners at the Eleventh and Twelfth censuses can not be made, by reason of the fact that in VM}-2 the num- ber of employees was reduced to the basis of prac- tically continuous work (30(.> days) during the year. However, out of a total of 37,707 employees reported in 1889, 19,708 were returned as working below ground. The miners and laborers below ground, who may be considered as representing miners and miners' helpers, showed a total of 18,911 in 1889. The miners engaged in large open-cut operations were classed as laborers, and if the number of these l)e added to the above total, and this again corrected for the employees who were not actually helpers, the resulting figure indicates that practically the same ratio held good in 1889 as in 1902, namely, that about one-half of the wage-earners at iron ore mines may be considered as having actually dug the ore. Table 14 shows also that a number of the miners worked above ground, and that a large pi-oportion of the unclassified labor was employed below the surface. The unclassified labor represented about 29.9 per cent of all those engaged in the iron ore industry. This is accounted for by the fact that in a number of the large open-cut mines, where the operations were carried on b}' steam shovel, the only skilled help was really those engaged in the handling of machinery, trains, etc. Talile 6 shows for 1902 the distribution of wage- earners according to daily rates of pay, liy states. Table fi.— DISTRIBUTION' OF WA(;E-1:ARNERS ACCORDIN than 1,0(10 wao-e-earners, and also for New York, which is the only other state in which the numl)er of wage-earners ap- proximated 1,000. These 9 states gave einploynKMit to 3ti,687 wage-earners, or '.i-t.4 per cent of the tolal niini- ber employed in this industry in the United States. Of the states for which statistics arc presented sepa- rately, ^linncsota, shows the highest rates of pay, '.t7. t per cent of the wage-earners haxing received at least $1.75 per day, and 34.5 per cent of these $2.25 per day or over. The rates of pay were only slightly lower in Michigan and Wisconsin. In the former state 11.2 per cent received between §1.50 and $1.71, while in Wis- consin the proportion with rates of $2.25 or over was considerably smaller than in Minnesota. Michigan, Minnesota, and Wisconsin constitute the Lake Superior district, and the rates in these 3 states were materially higher than those in the other states. In each of the 3 states of the Lake Superior district the bulk of the wage-earners received $2 per day or over, while in each of the other states for whitdi statistics are shown separately, practically all the wage-earners received less than $2 per day. The state in which the daily rates of pay approached most nearly those of the Lake Superior district is New .Tei'sey, where the range of wages for 91.4 per cent of the employees was from $1.25 to $l.lMt. New York, Alabama, Pennsylvania, and AV'isconsin follow in the order named. New Yoi'k shows a considerable number with rates of less than $1.25 per day and a cf>nipara- ti\'ely small mmiber who I'cceived as nuich as fl.75. In Alal)ama the bulk of the wage-earners, 89.3 per cent, received between $1 and $1.99. There was verj^ little ditterence on the whole between the rates paid in Pennsylvania and those paid in Tennessee. The pro- portion receiving $1.75 oi' over was greater in Tennes- see, but the number who received less than $1 was so large as to offset this. Rates were lower on the whole in Virginia than in any other state which rejjorted a large number of wage-earners, only 7.1 per cent of the total number having l»een paid as much as $1.50 to $1.74 per day. Table 7 .shows the distribution of the wage-earners employed in 1902 in the mining of iron ore among the several occupations and according to daily rates of pay. For each occupation the average numlier employed dur- ing the year at specified rates, and the percentages which these numbers form of the total luunber, are given. In an additional colunm these percentages are accumulated, thus rendering it possible to determine what proportion of the total number received as much as, or more than, a given rate.

Most of the engineers are, however, concentrated in the $-2 group, and the two groups below, 71.3 per cent, receiving between $1.50 and $2.24. The wages for firemen are seen to be somewhat lower than those for engineers. For firemen the lower-limit median rate group is $1.75, while for engineers it is $2; in each case a greater number of employees is included in the median group than in an}' other. The range of wages for over 82 per cent of machinists was from $1.50 to $2.74. The median rate lies between $2 and $2.24, and the distribution both above and below that rate is comparatively regular. In this occu- pation, also, the median grouf) comprises a greater nimiber of men than is found at anj^ other rate. The table shows a very wide range in the rates paid to miners. The wages for the bulk of the employees ranged from $1 to $2.74, with the median at $2. Bj- far the greater portion of miners' helpers are concen- trated in three wage groups, the range for 76.9 per cent being from $1.50 to $2.24. The median wage for timbermen and track laj'ers was between $2 and $2.24, and the bulk of the employees received from $1.50 to $2.74. Almost half of the boys employed, 48.3 per cent, received between 50 cents and 75 cents; 27.2 per cent received less than 50 cents, and 19.1 per cent received between 75 cents and $1. The median rate for all other wage-earners was between $1.75 and $1.99. The wages for 92.3 per cent of the total number ranged from 75 cents to $2.24. In the j'ear 1889, also, data in regard to the wages paid the different classes of labor, both above and below ground, were obtained.

This power was applied chiefly through 1,132 steam engines, with a horsepower of 102,87.s, or 80 per cent of the total. There were also 11 gas or gasoline engines with a horse- power of 86, 11 water wheels having a horsepower of 1,010, and 260 miscellaneous appliances with a horse- power of 15,444. In addition to this primary power 35 electric motors were used, theii- total horsepower being 937; 140 horsepower was rented to other establishments. At the census of 1889, 1,109 steam boilei's, with a total horsepower capacity of 57,976, were reported by iron ore mines. It was stated in the report on iron ore at that census that these boilers furnished steam to 1,093. steam engines, including air compressors, hoist- ing machinery, and engines for driving washeries, etc. In 1902 the mechanical power was applied for the pur- poses for which power is commonl}^ employed in mining work, namely, for hoisting the ore from the shaft, for subse([uent beneticiating treatment, for operating steam shovels and dredges in open-cut mining, pumping and ventilating machinery, mechanical haulage, air com- pressors, electric lighting, drills, etc. Table 14 shows also the distribution of the power among the several states; Michigan led in the horse- power employed, having 47,395 horsepower, or 39.6 per cent of the total; Minnesota had 25,332 horsepower, or 21.2 per cent of the total; Alabama, 1O.370 horse- power, or .S.7 per cent; New Jerse}', 6,684 horsepower, or 5.6 per cent; and New York, 6,015, or 5 per cent. In the other states the amount of mechanical power used was smaller, but on the whole proportionate to the extent of their operations. Production. — At the Eighth and Ninth censuses the statistics of production were not collected in the same manner as in subsequent census years. In 1860 the number of tons of ivo\i ore mined bj- the owners of lilast furnaces was reported separately from the pro- duction of what were considered strictly mining com- panies. The report shows that the blast furnace estab- lishments used 2,309,975 short tons in 18tiO, and that in addition 9(18,300 short tons were produced by mining companies, a total of 3,218,275 short tons, equivalent to 2,873,460 long tons. In 1870 the total amount of iron ore produced by the mines reporting was 3,395,718 short tons, equivalent to 3,031,891 long tons; in addition some ore was pro- duced I)}- the owners of blast furnaces which the Bureau of the Census estimated at from 800.000 to 900.000 long tons, so that, taking the first named figure, at least 3,831,891 long tons of iron ore were mined in 1870. At the Tenth, P^leventh, and Twelfth censuses the data were obtained from all mines irrespective of their own- ership or their relation to blast furnaces. The follow- ing statement gives a comparison of the figures for these censuses: Prodnctiun itf iron ore: JS60 io 1902. CENSl'H YEAR. Quantity (long tons).

In IStOO, according to the figures of the United States Geological Sur\'e_v (the cen- sus of 1902 was taken at a time thirteen years removed from 1889), the proportion over 1889 was ahnost iden- tical. Thus, in every decade since 1870 the production of iron ore in the United States has practically been doubled. The following table presents for each class of iron ore the amount produced in the census years 1902, 1889, and 1880, together with the percentages which these amounts formed of the total for all classes: Table 8. — Pruductiun uf iron ores hij viiriettex, witli per cent of total: 1903, 1889, and 1880.

There has been an increasing preference for rich and easily smelted iron ores, and considering the ditfcrent varieties of ore, it will be found that the amount of red hematite reported in 1880 was but 31.5 per cent; in 1889, 62.1 per cent; and in 1902, 85.9 per cent of the total outiDut. The brown hematite, although augment- ing in the amounts mined, indicates a decided decrease in percentages of the total; from 1,918,622 long tons in 1880 this class of ore increased to 2,523,087 long tons in 1889 and 3,305.181 long tons in 1902, the percent- ages at the three censuses l)eing respectively 26.9, 17.1, and 9.3 2:»er cent. On the other hand, the magnetites and carbonates have shown a decline, not only in total production, but also in percentage. The former con- tributed 30 per cent (2,134,276 tons) of the total in 1880, 17.2 per cent (2,506.41.5) in 1889, and 4.7 per cent (1,688,860) in 1902. The carbonate ore has fallen from 823,471 long tons, 11.6 per cent, in 1880 to but 27,642 tons, one-tenth of 1 per cent, of the total in 1902.

Con.?idering the individual states it is evident that those located in the Lake Superior region and in the Southern and Western states have shown an almost con- stant increase. In the ^liddle Atlantic and New Eng- land states, however, the bog, brown hematite, fossil, and magnetite ores, which formerly were the chief reli- ance of the local blast furnaces, have been replaced by the richer Lake Superior ores, and therefore show a marked falling off. The states will be considered in the order of their prominence in 1902. Ji/;//>/r.sy>^rt.— This state in 1902 contributed 15,137,650 long tons of iron ore, a greater amount than was pro- duced by the entire country in 18S9. This shows the unprecedented increase in thirteen years of eighteen times the amount contrilnited in 188!t, viz, 864,508 long tons, when Minnesota occupied tifth position, while in the previous census year, 1880, no iron ore was mined in the .state, the first production l)eingin the year 1.884. Since the year last mentioned the state has shown a phenomenal and practically an uninterrupted advance in the yearly output, l^he ore is obtained from the Vermilion and Mesabi ranges, that secured from the former being a hard specular or red hematite ore, while in the latter the red and brown hematites are much softer and in many localities rpiite finely comminuted. No true limonite ore is shipped from Minnesota, but the degree of hydration of some of the red hematites and the prevailing color encouraged the trade recogni- tion of pai't of the state's product as brown hematite. 404 MINES AND QUARRIES.

The output increased in 1889 to 5.8.56,169 long tons, Michigan rank- ing first and continuing to hold that position until 1901. In 1902 the production was 11,135,215 long tons, nearly ' double that at the previous census. The greater por- tion of this ore was of high grade, although in late years some siliceous ores comparatively low in iron content and also low in phosphorus have been won for use as a mixture in the furnaces with richer ores low in silica. The three I'anges from which this ore was mined, the Marquette, Menominee, and Gogebic ranges, are all located closer to shipping ports and to the prin- cipal pig iron manufacturing centers than the Minne- sota ranges, and the ores therefore command a higher relative value at the mine than those of Minnesota, as will be seen from the following statement: I'roduclion and value of Mirhiijan iron, ore: 18S0 to WOil.

The extensive deposits of fossil ores, particularly in the Birmingham district, located close to supplies of fuel and flux, were, however, the foundation of an important pig iron industry, and the amount of ore mined increa.sed in 1889 to 1.570,319 long tons, which was more than doubled in the year 1902, when 3,574,474 long tons were won, as shown in the statement below. These ores, however, are not of so high a grade, nor are their values so great, as those of the Lake Superior district. In addition to the red hematite ores referred to, important deposits of brown hematite have been developed, and this chtss of mineral represents about one-third of the iron ore siq^ply of the state.

The production for 1880 in Virginia and West A^irginia was 217.448 long tons. The output in 1889 was 511,255 long tons, and in 1902, 9.s7,95S long tons. The iron ore supply of the Virginias has been supplemented in late years by the importation of iron ores from the Lake Superior region. Most of the iron ores now ob- tained in the Virginias are of the brown hematite variety, !)ut some red hematites and magnetites are also mined.

Fuels, iron ores, and flux(>s, com- ponents of commercial pig iron, in passing through blast furnaces, ])roduce either pig iron in merchantalile form or liquid metal, to be carried to Bessemer con- verters or open-hearth furnaces. In 1902 an effort was made on behalf of the Canadian govermiient in ecpiat- ing l)onuses to iron industries, to discriminate against li(iuid metal being classed as pig iron, but the conten- tion was not sustained, and commercially the entire product of ))last Furnaces smelting iron ore is considered and reixirted for statistical purposes as piv- iron. IRON ORE. 407 t^n- the production of the quantity of piy nietul •^■vedited to the United States in the year I'.tO'J there were required about 30,(»()0,000 tons of T)itiuninous coal (the laru-er portion of Avhich Avas converted into coke) and al)out one niillion and a half tons of anthracite coal. In addition to mineral fuel prol)al)ly ;!.')(>, (Hio tons, ov 3S,(>0(),()ou bushels of charcoal were consumed in l)last furnaees. About 33,000,000 tons of iron ovv were fed to the furnaces, and the tlux necessary to carry away the impurities of the ores is estimated at al)Out eiji'ht and a half million tons. Therefore, to supply the lilast furnaces of the United States in 1902, which produced nearly 1S,( (00,000 tons of pii;' iron, there were recjuired •about 73.000,000 tons of raw materials. In the manufacture of pig iron a considerable cjuantity of rolling mill cinder, roll scale, etc., is produced which is also employed practically as ore. Some "' blue billy " or "purple ore,'' resulting frOm the calcination of pyrites and the residuum from roasting ferriferous and manganiferous zinc ores, are also utilized. The total amount of iron ore and of materials used as ore made available in the United States in 1902 may be approxi- mated as follows: T.ins. 35, riH7,41() 1,165,470 1 , S)00, 000 Domestic iron ores Foreign iron ores Roll scale, mill cinder, l)lue billy, etc Total . 88, (K2, K,S0 Some iron ore is employed for other purposes than for the manufacture of pig iron. It forms an impor- tant part of the charge of many open-hearth steel f lu-- naces, and is used also for tix in puddling and other furnaces, for flux in silver smelting, and in making- metallic paints. After making allowance for the other materials that are used as ore and deducting the ([uan- titj" of ore which is applied to purposes other than iron production, the actual (piantity of iron ore and ma- terials used as ore entering into the manufacture of pig- iron in VM)-2 is found to be, approximately, 33.0(.>0,000 long tons. The active demand for iron ore to maintain in opera- tion the blast furnaces of the United States, and the expectation that this demand would continue, was responsible to a great extent for the phenomenally large output of the iron ore mines in the year 1902. Large stocks of ore accumulated at or near blast fur- nace plants aided in swelling the total iron ore supply to figures never before reached and which may not be exceeded in the near future. CLASSIFICATION OF I HON ORK. Iron ore may be considered in foiu- general conunei-- cial classes, as follows: (1) Red hematite, including all anhydrous hematites, known >)y various names, such as red hematite, specu- lar, micaceous, fossil or slate iron ore, martite. blue hematite, etc. (2) Brown hematite, including the varieties of hy- drated sesquioxirlc of iron, recognized as limonite, goethite, turgite, bog ores, pip(> oi'es, etc. (3) Magnetite, an ore in which the iron occurs as magnetic oxide and whi<-h includes some martite, mined with the magnetite. Martite is a red hematite ore which preser\-es to a varying extent the crystal- line form of magnetit(\ but which is nonmagnetic oi' nearly so. (1) Uarbonates comprise those ores which contain a considerable amount of carl)onic acid, such as spathic ore, blackband, siclerite, clay ironstone, etc. This classification is to be considered as general, the ores having various local or trade names. Thus the prevailing color or general physical appearance is used to indicate an ore, as blue, black, red, or brown, mica- ceous or glistening hematite. The term "specular," although more properly applied to a glistening ore, is by custom gi\'en to many dull red hematites. Other hematites receive designations according to their topo- graphical or geographical occurrence, . as "fossil,"' "mountain," or "A'alley" ore, or to the structure, as "flaxseed" ore, "slate" ore, etc. In the brown hema- tite class " limonite," "turgite," etc., are mineralogical terms referring to the degree of hydration. Init the physical stiucture and appearance of some of the ores are described by the term "lump" ore, "pipe" ore, " liotryoidal" ore, " needle" ore, etc. The beneficiating of l)ro\vn hematites has given rise to the terms "wash" ore, "sand" ore, etc. The carbonate ores are known as spathic ore, limestone ore, Itlackband ore, kidney I ore, etc. The association of other substances with iron also furnishes names to certain ores, such as pyrite, pyrrho- ! tite, ilmenite, chromite, etc., but in this discussion it is not essential that either the chemical, mineralogical, or physical features of the various ores should be consid- ered in detail. The early iron industry of the United States was based largel}* upon bog ores, limonites. or other forms of brown hematites, t)btained at points convenient to the Atlantic seaboard. Magnetites also were emploj-ed at first by means of a direct process wherelty, in Catalan forges, the ores were reduced and the result- ing metal forged into blooms or billets without passing through the casting process; subsequently magnetites as well as hematites were smelted in l)last furnaces. But the later de\'elopment of the iron industry and present great importance are due largely to the use of red hematite ore. The })rown hematites and red hematites are of the same chcnucal composition in so far as iron oxide is the ))asis of the ore. th(> primary dirt'erences being- structural and the lowei- percentages of combined and hv"-roscopic water in the red hematites. Red hematite, if free from other impurities, will yield 70 per cent of iron, and pure brown hematite, if thoroughly dried out 408 ]\IINE8 AND QUARRIES. and calcined to eliminate all water, will also yield the same proportion of iron. But if the ores are merely dried to drive off the moisture, which differs under varying- conditions, the amount of metallic iron possible in a pure red hematite is about To per cent, and in a pure brown hematite 60 per cent. However, iron ores seldom occur practically pure, the amounts of silica, alumina, lime, magnesia, and of such elements as mano-anese, chromium, sulphur, phosphorus, titanium, etc., reducing the actual percentage of metallic iron obtainable from ores. Magnetic ores are capaiile of yielding in the pure state more metal than any other ores, and pure magnetite would show 72.48 per cent of metallic iron, but mag- netites, like the hematites, are subject to deterioration from other elements which are present. The fourth form of iron ore is the carl)onate or spathic, in which the oxide of iron is associated with carbonic acid and genei'ally with lime. If this carbonic acid is driven off' by heat carbonate ores become prac- tically Ijrown hematites, but in the natural state the purest carbonate would not vield over 46.7 per cent oi iron. Consideral)le of the early iron industry, particu- larly in western Pennsyhania, eastern and southern Ohio, Kentucky, and ^Maryland, and also t<.i a <-crtain extent in eastern New York, was based upon the use of carbonate ores, but because of the facts that these ores in their natural state are '" lean," that they usuall}- occur in veins that must be worked underground, often deteri- orating as workings are extended, and that the ore must be roasted, the rjuantity of carbonate iron ores em- ployed has Ijeen greatly reduced, until in the year l'.tU2 only i!7,ti42 tons were used. In late years the quantity of magnetic iron ores util- ized annually in producing pig iron has increased but slightly, although some remarkal.)le deposits of these ores are available. But magnetites are not as i-eadily reduced as the hematites, are often dense and hard, arc liable to have an excess of sulphur, phosphoi'us, or titanium, or are so closely associated with the gangue matter as to make them lean, demanding that r(.)astiiig or some method of concentration, either by hydraulic or magnetic separators, should be employed. Brown hematites occui- mostly in pockets or lenses, but ai'e occasi(jnally found in strata, often associatixl closelv witli limestone, and also more or less intimately mixed witli chu's and siliceous matter. Conset[uently, many Ijrown hematites require washing to separate the clay and sand, and in some cases this washed ore is sub- sequent! j^ I'oasted to drive off' the excess of moisture. All methods of beneficiating ores, such as roasting, washing, and separating, add to the expense of produc- tion, and it is tlierefore not surprising that red hema- tites, which seldom retjuii-e preliminary treatment, have met with genci'al favoi'. This preference can also be explained h}' the fact that the ores are usually readilj^ reducible, and most of those mined yield satisfactory percentages of iron. Another feature of material ad- vantage is that man^' red hematites occur in large and well-defined lenses or bodies, permitting the exploiting of the deposits on a large scale by utilizing labor-saving appliances. The use of such appliances may extend from the winning of the ore at the mine to its delivery at the blast furnaces. Thus a large proportion of the red hematite ore from the Lake Superior region is never touched by mainial lalior. That which is obtained from open cut workings is in many cases dug by steam shovels which load the ore into standard railroad cars. In some underground mines manual laVjor is con- fined practically to directing the ore into '"mills'" and chutes, which discharge into mine cars, these cars being elevated and automatically dumped into bins from which standard railroad cars are loaded. In other un- dergromid operations it is necessar3' to shovel the ore liy hand into mine cars, but thereafter labor-saving ap- pliances are available. Most of the ore mined in the Lake Superior region is carried in standard railroad dump cars to shipping' docks, where it is dropped into bins, from which chutes convey it into the holds of vessels brought to the side of the docks. These vessels are unloaded by mechanit-al appliances, which deliver the ore either onto stock piles or into standard raili'oad cars, which carry it to the blast furnaces. At the blast furnace plants there are equally satisfactory mechanical appliances, such as car dumpers, which empty a loo.Ooo-pound car by reversing it. or tra\eling bridges, fitted with large buckets, which transfer to bins or to stock piles the ore dumped from the cars. These devices are so perfected that only a small amount of ore is touched by hand from the time it l("aves its native bed until it passes into the blast fur- nace, and while they are most in evidence in the Lake Superioi- region they are in use in coiniection with important iron ore mines in other ]iortions of the country. DISTRIBUTION' OF OEK DEPOSITS. The distrihution of iron ore throughout the L'nited States is general; there is no state in which iron ores of som(> kind are not found in considerahh^, quantities, but all are not available for use. In some cases the ores are too lean, that is, carry too small a percentage of iron; in others deleterious ele- ments, such as phosphorus, sulphur, silica, and titanium, are in excess. Some dejiosits are too far from desirable fuel, or too inconveni(>nt to blast furnaces, to make their immediate utilization practicable; others are in small Ijodies or veins, or are scattered over too large areas to make their exploitation profftal)le. It is probabh> that some of the undeveloped deposits may be exploited in IRON ORE. 409 tho near future as the development of newer .sections of the country makes fresh demands for iron, or as the extension of railroad facilities and water transportation brings the ores and fuel into convenient association. Improvements in smelting- and fluxing ores, which arc now considered undesirable because of the presence of some of the elements mentioned above, may also make the production of satisfactory metal from tiiese ores a commercial possibility. While the nr.uiager of a smelt- ing plant can obtain ores high in ii'on, or tliose which need no beneliciating treatment, at prices which permit him to produce metal at a satisfactory profit, he can not be expected to consider favorably supi)lying flic blast furnaces under his directit)n with inferior raw material. But the rapid increase in the output of the blast fur- naces to meet the growing demands of a de\-eloping country may in the near future encourage the utiliza- tit)n of ores which are now considered luidesirahle. While the statistical data is reported by states, except in such cases as would disclose individual statistics, a presentation of the industrj' according to prominent districts is ofi'ered as of interest, for the lines dividing- states are lost in anything affecting the industry of the nation. The statistics for these districts are i^resented in summarized form in Table 11. Thi> Lfil'e Si(jjit'/iif i-i-gioii. — The greatest de\-elop- ment of iron ore deposits in the world is in the Lake Superior region, which in 1902 produced 26,it7T.4ol: long- tons, or 76 per cent of the total output for the United States. No other section of the United States, and no other district in the world, has shown such marvelous development or produced so much iron ore as the region embracing parts of northern INIichigan and Wisconsin and the eastern portion of ^Minnesota. Whether in tlie same extent of territoiT elsewhere there may or may not be larger deposits of iron ore of equally desirable composition can not l)e asserted, for it is by develop- ment that these great properties have become known and their reserves approxiiuately determined. But to-day the Lake Superior region stands in a uni(jue po- sition by reason of the large quantity and generally superior character of iron (ires won from the hve ranges or subdistricts which it embraces. Some of these mines have been in operation for fifty years, a number of them for half that time, liut the largest annual pro- ducers are later developments. The initial shipment of iron ore from the Lake Superior region is credited to the year 1856; the devel- opment has advanced almost constantly, and about two- thirds of the total product since 1S56 has been taken from its mines in the last ten years. The production of iron ore in the Lake Superior region in the past decade and the quantity previously shipped are as follows: Pruduclidn of Luke Supcrinr iron ore, ls;iS In xliijriiicnlx. 1.90J, irilli 'jjrrrionx YEAK.

The output finds cheap transportation for the rail haul to the lakes, has grades favorable to the traffic, and on the lake shores expensive and well- equipped docks have been constructed at seven difi'erent ports, where the oi'c coming in train loads is received into liins, and delivered from the bins by gravity into the holds of vessels. The vessels take the ore from the shipping- docks and carry it through two or more of the Great Lakes to receiving docks where equal facilities for unloading by mechanical appliances have been pro- vided. In this way enormous quantities of ore are handled cheaply and expeditiously. The Lake Superior region is also unique in that its location is such that ore can be delivered at furnaces, in a populous section of the country, and there meet a cheap fuel sup])ly; in other words, its market facilities are unexcelled. It has been this which has chiefly encouraged the phenomenal development. The ([uantities of iron ore olttained from the h^'c ranges eraltraced in the Lake Superior region, taking- these in the order of their initial shipment, are as fol- lows: The Marcjuette range, in the northern peninsula of ^Michigan, has contrilmted since is.jlatotalof ri(_),915,21T long tons, or 3i> per cent of the entire production of the Lake Superior region. The Mencjuiinee range, south of the ^Marquette range and extending from the northern peninsula of ^Michigan across inti.> northern Wisconsin, has shipped, since 1877. 1:2,1:06.22s long tons, or 10 per cent of the entire production. The (xogebic range, west of the ]\ienominee and Mar- quette, partly in the northern peninsula of Michigan and partly in Wisconsin, has suiiplied, since 1881, 38,288,761 long tons, or 17 per cent of the entire production. The Vermilion range, in the eastern portion of the 410 MINES AND QUARRIES. state of Minnesotii, hafs, since 18S4, sent forwai'd 19.074,424 long tons, or 9 per cent of the entire production. The Mesabi range, in Minnesota, soutli of tlie Ver- milion range, in the brief interval since its opening in 1S92, has furnished 54, 041, .532 tons, or 25 per cent of the entire production of the region. The total production of these live ranges since their opening is 221,320, lt)2 tons, and adding 2,320 tons not credited to any particular range, the grand total for the Lake Superior i-egion is 221,328,482 tons. This far exceeds the quantity of iron ore won from any otiier mining district in the world, and the amount obtained in the year 1902 from these five ranges, which repre- sents their maxinuun production, is in excess of the entire production in one year of any foreign country. The cjuantity of ore won from the state of Minnesota in 1902 has only been exceeded by the yearly produc- tion of Great Britain in thii'teen years and of German}^ in six 3'ears. None of the other foreign countries has as j^et reached a total approximating this state's 1902 output. The Vermilion range, in Minnesota, was opened in the year 1884. The ore which is there produced is a hard specular, high in ii-on, and visually of Bessemer grade. This range is the farthest removed from the principal pig iron producing centers, and the high esteem in which the ore is held is shown by the fact that much of it traverses a distance of over 1,0(»0 miles to points of consumption. The two principal producing mines in this range are known as the Pioneer and the Chandler. Plate I is a surface \'iew of these mines, showing the shafts and various buildings connected with the mining operations, the large open cut, and the extent to which timber has been denuded for mine sup- ports and fuel. Plate il shows the Auburn mine, on the Mesabi range, in Minnesota. The ore in this deposit is won by the "milling" system, in which the surface earth is removed and the ore drawn througii "raises" into drifts located some distance lielow the top of the ore, making in this way large sinks or craters. This system retjuires that the cover be stripped, and is esjiecially adapted to shallow deposits of soft ore. The plate gives an excel- lent view of the crater which is formed by the mining. A steam shovel is at work loading ore cars, which are taken through the tunnel shown to the shaft, throuoli which it is elevated to tlie sui-face.

Tlie indine plane is shown hfittomed in oi'e, while ill the left of the illustration ar(^ si'eii the tunnels whidi are run hack in the ore. Operations have lifM'ii carried on at this mine liotli in open pits and iiiiflergi'ounfl. Ill some of the newer mines modern apparatus has been installed. Plate IV shows a view of a steel shaft frame at the Adams mine. It is provided with hoppers in which to receive ore from skip cars, and was one of the first of this class to be erected in the country. Plate V, a view on the Mesabi range, in. Minnesota, shows large deposits of ore. These are usually of a comparatively soft character, lying in nearlj^ horizontal strata and with covering of such slight depth that they can be easily stripped. The ore is won by means of steam shovels which place it directly on iron ore cars, in which it is hauled to the dodvs. In this way immense ([uantities of ore are cheaply and easih' obtained. It is owing principally to these mines that Minnesota shows a larger production per employee than any of the other states. The view presented herewith shows the Mountain Iron mine, located at Mountain Iron, Minn., in which three steam shovels are shown, one being at work, as seen at the top of the picture, stripping the ore, while in the foreground another shovel is engaged in loading the cars, and on the right-hand side a third shovel is at work. Around some of the more important mines in the Lake Superior region towns have sprung up, which are dependent entirely upon the iron ore industry. Plate VI shows a group of mine buildings, crusher house, A and B shafts, and some of the dwelling houses located at the Clifi's Shaft mine on Lake Bancroft, Mich., and gives a good idea of the general surface appearance of a well conducted Lake Superior iron ore mine. The earliest mining in the Lake Superior district was on the ^Marquette range and one of the oldest opera- tions is the Cleveland mine, which has been supplying ore constantly for a period of over fifty years. Plate VII shows a general view of the Cleveland Lake mine of the Cleveland Clifi's C'ompany. looking from the east. The shaft houses, ore piles, and dumps are shown, together with the ore cars. In the foreground are im- mense piles of lumber. The lake bed, drained for the purpose of (Extending mining operations, may also be seen. Most of the iron ore won in Michigan is taken from underground mines; the only views obtainable of these are such as ar(> taken by Hash light. Plate VIII illus- trates the Clifi's Shaft mine, one of the more prominent on the Marquette range in Michigan.

In the suninier of 190H the L;ike Superior Iron ]\Iin- iiig Company, a pioneer of the region, celebrated the liftieth year of its activity, and the following statement, IRON ORE. 411 which embraces the salient points of a contribution for the occasion by the author of this report, enipliasizcs the development referred to: Neither the records of the production of the Lake Superior region nor the annual reports of the American Iron and Steel Association go back beyond 1854; therefore no data earlier than this will he exact. In 1854 there was one mine reported as operating in tlie Mar- quette range, the shipments amounting to 3,000 tons. In 1902 tlie shipments of the JIarquette range were 3,868,025 tons, the lake shipments from all ranges in that year reaching a total of 27,0;(9,169 tons. The production or consumption nf iron ore in the United States in 1854 can only be estimated from the quantity of pig iron made. According to the census statistics of 1850 there would have been in the neighborhood of 1, ,500,000 tons of iron ore consumed during that year, for there was made in the country 563,775 tons of pig iron. In 1854, according to the reports of the American Ir(jn and Steel Association, 736,218 net tons, equivalent to 657,337 gross tons, of pig iron required about 1,750,000 tons of iron ore, whereas in 1902 the country produced 17,821,307 gross tone of pig iron, and the domestic output of all the iron ore mines in the country for 1902 was 35,567,410 long tons. At least 137 producing mines are now active in the Lake Superior region, a number having exceeded annual outputs of 1,000,000 tons, and one mine has approximated 2,000,000 tons in a year. The estimated iron ore production of the country in 1854 approximated 1,75(1,000 tons, based upon the reported pig iron production, and the yield of ores did not exceed an average of 40 per cent of metallic iron. Therefore, it is doubtful if in 1854 the United States produced as much iron ore as the Fayal mine in Minnesota did in 1902, which in that year shipped 1,919,172 tons. Considered on the basis of metallic contents, however, this output of the Fayal mine prol)al.)ly produced as much pig iron as was made in the United States in any year up to 1866. In order to indicate the chemical composition of the iron ores obtained from the Lake Superior district the following statements have been prepared. The first shows what may be considered as representative com- positions of standard ores of each of the ranges; and in tlie second the analyses are for the lower grade ores, which are employed largely because of high silica and low phosphorous contents. These anal3'ses are of ores in their natural condition, and rei^resent cargo lots. Determinations of ores obtained from individual mines in each of the ranges will vary from those given in the statements. Typical analyse.'' of Lake Superior iron ores. CONTENT.

In 1902 Alabama supplied 3,574,474 tons, (Jeorgia 830,554 tons, and Tennessee S74,542 tons, making a total for this district of 4,779,570 tons of iron ore. The bulk of the Alabama ores are red hematites, these ores being largely mined convenient to Birming- ham. There is, however, a considerable quantitv of brown hematite mined in Alabama and also in Georgia and Tennessee. A statement covering the classification of ores in these three states for the year 1902 may be summarized as follows: Prdductioii of iron orex, Soulhern tlixtricl, hy xtates anil rarielie.'c 1H03.

The red hematites are locally recognized as soft and hard ores, the former, being at or near the surface, are partially decomposed; the lattei' are mined by underground workings and may lie sul)clivided into siliceous ores, in which silica is present in (piantity, and '' limey"" ores, in which the proportion of lime may be such as to make the ore approximately self-fluxing. Nearly parallel with the Red mountain deposits are important beds of brown hematite and limonite ore, occurring in isolated deposits, some of large extent. In fact, the exploited brown hematite deposits of this region are of greater average extent than those found in other portions of the countiy. Occasional deposits of magnetite are also found in the Alabama-Tennessee district, but few have been worked. Some carbonate ore has also been won and used in the manufacture of special irons. Plate X illustrates the openings at one of the Red mountain mines near Birmingham. Plate XI is a view of a limonite bank near Tecumseh, Cherokee county, Ala.; the ore is broken down, loaded onto tram cars, as shown, and taken to washers, from which it goes to the railroad cars. JS^eir Yuri' iiml Xeir Emjland. — Magnetite iron ores are produced chiefly in New York, New Jersey, and Pennsylvania, but some are won from North Carolina, Michigan, New Mexico, and Utah. The deposits of 41; MINP]S AND QUARRIES. this class of mineral in New York state arc phenome- nally large, and so far as metallic contents arc con- cerned, unusually rich; but many carry phosphorus, sulphur, or titanium in excess, some of the most exten- sive deposits having- so much titanium that they have not been brought into commercial use. High phos- phorous ores, however, have l.)pen and are mined to a large extent, and l)eneticiated ))y magnetic concentra- tion. Some ores in the vicinity of Port Henry, N, Y,, carry as high as 3 per cent of phosphorus, as apatite, mixed with the magnetic crystals, which, after the ore is comminuted, can he readily separated, either by mag- netic separatoi's or by jigs. Other ores of the Port Henrjr mines district are of Bessemer grade, and from one opening 3(», 00(1 tons of very high grade magnetic ore were obtained. This ore approached chemical pu- rity, was of Bessemer grade as to phosphorus contents, and was practicallv a mass of well-detined octahedral crystalline forms, some an inch and a quarter on the face, man}' having practically perfect proportions. Still larger sized crystals have been found, but these were more or less imperfect, and masses of crystals affected by pressure had some faces flattened. The localities which liavc been worked in tlie Lake Champlain district arc the mines at Chatt'augay, west of Plattsburg; the mines at ]\Ioriah, west of Port Henry; and those west of Crown Point. These deposits are at elevations of from 6 the level of Lake Champlain, and while some explorations (jriginally developed Ijcds of considerable size by an (jpen cut, most of the mining is now underground, and much of it at a depth of .500 feet or more. Some mines which have been exploited are adjacent to the shore of the lake, others are close to tlie Adirondack momitains, and some are on the western side of the I'ange. I'roinincnt among the titaniferous ore deposits are the Si)lit Rock mine, on Lake Champlain. and thr Adirondack \'illage mine, close to the main Adirondack range. These titan- ifei'ous ores were utilized in former years by the Cat- alan or direct process, in which the ore was c(inv(.'rte(i into metal )»y charcoal in open hearths. The Port Henry mines, located at .'\Iin(»\ ille, near Lake Champlain, in Essex county, have Icjng been fa- mous as a source of iron ore supjjly; it is claimed that the hrst ore was taken out in 1K04. The ore is a dense magnetite, and Plate XII is a A'iew of No. -Zl mine of the Port Henry Iron Ore Com]iany. It shows the large pillars of jjure ore left to support the I'oof of tlie mine, the operations now lieing pi'actically all undeig'round. It is estimated that there are in the jjillarsof this mine and of the mines adjoining, belonging to AVitherhec, Shei-man & Co., at least S00,()()0 tons of ore. The de- posit is very large, ha\'ing a thi(;kness in s(jme places of i -100 feet. The ore bodies are dividcfl into two parts by ahorse of I'ock, and at the lower de])tli diamond drill- ings have indicated the existence of two nnderl\'ing veins of on^ high in iron and phosphorus and low in i silica. The ore which is sold in the market is high in iron, but also contains phosphorus in the form of apa- tite, making it all of non-Bessemer quality. Other deposits of magnetite occur in the Iludson river district, the most pronounced exposures and veins being south of West Point on the Highlands east of the Hudson river, extending as far as Croton Falls, but some magnetite is also found west of the river, and this line of deposits can be traced from New York into New flersey. The southern New York magnetites are. as a rule, lean, and contain either an excess of phosphorus or, more frequently, of sulphui'. There lias been con- siderable exploitation of these deposits, but outside of the Till}^ Foster mine none has been a large producer, and all are inactive. The Tilly Foster appeared to be a large lens, which was worked first as an open bed, then the ore body was followed bj' shafting, the rooms being tilled with concrete arches to permit the removal of pillars, and finally the working was restored to an open pit by the removal of 600,000 cubic yards of over- lying rock. Large expenditures were also made on the Theall mine, near Brewster, which was worked y)y an extensive tunnel with stopes, shafts, and galleries. A concentrating plant was er(>cted at this mine, liut sub- sequently dismantled. The Benson luine in northern New York, west of the Adirondack mountains, has also installed a separating plant, and has produced mer- chantable concentrates in considerable quantity from lean magnetites. The Lake Chaiuplain district has been prominent in the efforts to beneticiate ores by con- centration by the use of jigs, and also l)y magnetic separators. At the Port Henry mines is the' largest separator plant in the country. New York is one of the few states where, in addition to the magnetites, the three other varieties of iron ore ar(> found. Red hematite is mined fi'om the north centi'al poi'tion of the state, in Jefferson, Clinton, and Oneida counties; brown hematites are won in the south- ern portion, east of the Hudson river, in Dutchess and t'oluinbia counties, and in the same district carbonate oi'c has been found to a considerable extent, and a large ])lant for roasting these ores has been constructed near Catskill Landi]ig. Some of the brown hematite luines along the ITarlem Railroad ha\'e been worke(l for many years, and have been, and are still, the main reliance of the charcoal iron industi'y along the Conncctit'ut and JS'ew York boundary, 'i'his same class of ores extends into Litch- lield county. Conn., and Berkshire county, jNIass., the district being generally recognized as the Salisburv region. The lapid denudation of available tind)er, and the necessity of oi)ci'ating small blast furnace plants producing a special grade of pig iron, has reduced the mimber of furnaces, so that now only a fewarc^ making ircjn with charcoal; these smelt brown hc^nalite and some carbonate ores. In addition to the brown hematite ores mentioned as IRON ORE. 413 occurviny in southwestern Massachusetts and north- wosteru Connecticut, hog ores arc found in eastern Massachusetts, and were the foundation up(jn which the; hrst practical development of the iron industry in the nited States was based. Magnetic ore occui's in Khode Island, and mag-netites and hrown hematites have been mined in Maine and Vermont. 3 t'w Jefscij. — The magnetite ores extendi ng from New- York across northern New .Jersey into Pennsylvania, hav(^ been liberally developed in a munber of locations in New Jersey. The importance of the industry, how- ever, has declined in late years, the bulk of the produ('t being confined to a few of the more important mines. As a rule, the ores of New Jersey are lean, and some of them carry sulphur or phosphorus in excess, Ijut others are of Bessemer grade. In western New Jersey magne- tites also occur in a decomposed condition, and carry considerable manganese. Brown hematites are found in western New Jersey, in the vicinity of Belvidere, but have not been extensively developed. The early iron industry of New Jersey was based upon the use of bog ores, which came from the district close to the ot'ean front; these are no longer used, and all of the ore won in New Jersey is of the )nagnetite class. The beneticia- tion of magnetic ores by washing and 1)y separation has reached a development in New Jersey approximating that of the state of New York. The failure of some of the more pretentious magnetic separating plants, whicli comminuted ore finely, has encouraged magnetic cob- bing and the treatment of ore as coarse grains by sep- arators. The roasting of dense ores is also a feature of New Jersey blast furnace practice. PennHi/Jvaiiui. — Peiuisyhania, although not the pio- neer in American iron industry (its initial enterprise having been estalilished about ITlti), rapidly advanced to iirst place, and by reason of the wide distril)ution of all classes of iron ore and alnindance of fuel, ))ecame the largest producer of iron, and still holds that rank, although the bulk of the iron ore used in tiie manufac- ture of its iron and steel products is mined outside of the state. The most important iron mining operation in Penn- sylvania is that carried on in the Cornwall ore deposit in Lebanon county, which has produced about three- fourths of a million tons aniuially, and, since the year 1740, has contributed a total approximating eighteen million tons to supply Pennsylvania iron works. This ore as mined yields on the average about 4fj per cent of iron, carries about three-fourths of 1 per cent of copper, and about 2i- per cent of sulphur. It nuist, therefore, be roasted, and ore-roasting kilns have here obtained their largest development. Furnaces of the (Ijers cylindrical form, using solid fuel, are used at some plants, and at others there are circular or rectangular kilns heati>d by producer gas after the Davis-Colby patents. The Cornwall ore bank, at (!ornwall, Lebanon county. is a large de])Osit of magnetite from which inunense quantities of ore have been won. Most of thi' ore is obtained above water lev(d, cars being riii] in on a series of terraces. The ore is ])i-oken down and loaded onto cai's by means of barrows, and thus transported to the furnaces. Plate Xlll shows two terraces in solid ore, with the workmen engaged in tilling tiie oit cai's. In the back- ground of the j)icture a stilj^ping whicli covers the ore can be seen. Along the iSouth moLuitaiii. fi'oni the Delaware ri\'er to and Ijcyond the Sus((U(4ianiia river, deposits of mag- netic iron ores are found and have been worked. In Ijchigh and Lancaster counties at present they are mined chieHy for concentration, as the ore is lean. ]\\ Berks county a large underground development was niad(! at Boyertown, some shafts extending over flOD feet in deptli, the ore being, as a rule, low in phos- phorus but high in sulphur, and requiring roasting. These mines are being unwatered to make it possible to obtain ore. Between Boyertown and Cornwall a number of magnetic deposits have been worked spas- modically, and beyond the Susquehanna, in Adams and York counties, similar mines ha-^-e l)een in operati(jn. In Lancaster county a magnetic concentrating plant has lateljf been installed, operating on a large mass of lean magnetite, which is crushed, sized, and separated, the object being to form the concentrates into briquettes for use in blast furnaces. Along the northern and v\'estcrn faces of the South mountain, and in the valley between the South and North momitain ranges, l)rown hematite ore has been mined in many localities, some of, the deposits having l)een worked on a liberal scale, and others, producing but little, have a history approximating a century of time. As a rule, these brown hematites require wasli- ing to make them desirable for blast furnace purposes, and they yield, after such treatment, al)out 4.5 per cent of iron, some with 2 to 5 per cent of manganese, and all with phosphorus above the Bessemer limit. Other brown hematites of nearly similar composition occur in central Pemisylvania, along the eastern flank of the foothills of the Allegheny mountains, in Bedford. Cen- ter, Huntingdon, and other counties. In the same re- gion fossil and red hematites are won by underground operations, and this is true also of deposits in north- eastern Pennsyh'ania, along the Blue mountain range, and in the vicinity of Danville and Bloomsburg. Prac- tically all of the brown hematites have been won from open cut wcu'kings, the ore occurring with clay and limestone, and re(juiring washing. ^luch of the red hematite was mined from small underground drifts. In the liitumiiKJus coal belt, which extends across Pennsyh'ania from northeast to southwest, with the Allegheny mountains as an axis, the carl)onate ores obtained were formerly an important base of supply. The location of many of these ores in small veins, the 414 MINES AND QUARRIES. exploitation of which is expensive, the necessity of roasting them, and their generally high phosphorus content have much limited their use. Dclavai'e and Jfifri/hiiiJ. — In Delaware there are several isolated deposits of brown hematite which have been worked but are now inactive. In eastern Mary- land carbonates which occur njixed with clay are luined in a desultory way )>y farmers and used near the city of Washington to produce a special grade of pig metal with charcoal. In M'estern Maryland there are brown hematites in considerable cpiantities, also indications of red hematites, and some lean magnetites, which, while appearing to occur in large proportions, would have to be concentrated to be merchantable. Tlie Vhyihids and Carol in an. — In Virginia the bulk of the iron ores mined are of the brown hematite class, some occurring in beds of cla}-, others in a form ap- proaching veins embedded in rock strata. Minor deposits of red hematite also exist, and in southwestern Virginia and in western North Carolina there are large bodies of magnetites. Titaniferous magnetites and brown hematites occur in central North Carolina and extend into South Carolina, Georgia, Tennessee, and Alabama. The Appalachian mountain chain is bordered by iron ore deposits from northern New York through New Jersey, Pennsjdvania, Maryland, the Virginias, North Carolina, Tennessee, Georgia, and Alabama. These deposits are mostly magnetites and 1>rown hematites, the latter generally showing in the \alleys, the former often in foothills or on the slopes of the mountains. Some red hematites are also found on the mountain slopes. Nearly paralleling the Appalachian range, and occup3'ing positions in the foothills of the Allegheny mountains, are deposits of brown hematite, also of car- bonates. The carbonates are mor(i abundant in the coal beai'ing regions, and occur on ))oth flanks of the Allegheny mountains. Still farther west carbonate ores and some brown hematites are found in the coal measures of western Pennsylvania, West Virginia, Gliio, Kentucky, and eastern Tennessee; red and brown hematite are abun- dant in Kentucky and Tennessee. Ohio. — The ores obtained from Ohio and from the portion of Kentucky adjacent to the Ohio river arc either carbonates or hematites, resulting from the weathering of car))onates; these have sustained a con- siderable iron industry for many years in southei-n Ohio and in Kentucky, in a locality' known as the Hanging- Rock region, with Ironton, Ohio, and Ashland, Kv-. as business centers. The original installations were all charcoal furnaces, some of which are still acti\'e; for a time some furnaces used raw bituminous coal, but the larger plants are now dependent on coke, local ores being used, supplemented by other ores from the Lake Superior region. There are also in Kejitucky excellent deposits of limonite, and these extend into Tennessee, some quite important mines existing in the central and western portions of the state. There are also carbonates in the southwestern section which extend into Mississippi. Carbonate ore also exists in northern Florida. Wijicoihsin avd loim. — The liberal exploitation of the iron ores in the. Lake Superior I'egion has directed atten- tion to deposits in adjacent states. In central Wisconsin brown hematite exists in pockets or lenses. In southern Wisconsin there is a unique deposit of high phosphorus red hematite ore, wdiich, owing to its physical structure, is known as flaxseed ore, and an apparently large quan- tity of red hematite of excellent composition has also lately been discovered \>\ drilling and shafting in the vicinity of North Freedom, Sauk county, Wis. This deposit is expected to be a factor in the iron ore supplj^ of Chicago and vicinity. In northeastern Iowa brown hematites have been wrought, and carbonates are found in the western section of the state. Jfi.ssoari and Arhmviis. — Missouri attained promi- nence as an iron producing state several decades ago through the Iron Mountain and Pilot Knob deposits, which gave promise of being large producers, hut as development proceeded these ore beds were practically exhausted, although it is possible there may be undis- covered extensions of them. In central, eastern, and southern Missouri red hematite and brown hematite ores are obtained in quantities, and these ores also ex- tend into Arkansas, although there has been no devel- opment in that state. Texas. — The exploitations for iron ore in Texas have been chiefly in the northeastei-n section, where brown hematites have l)een won from near the surface, and the fact that these lie in nearly horizontal layers, covered })ut slightly with a ferruginous sandstone and sand, suggests that they are bog ores fornnng the bottom of an extinct lake. They extend o\er a large territory, I except whei-e the plateaus are cut by water courses. In central Texas an important deposit of red hematite ore, claimed to l)e of excellent (juality, has been opened up, l)ut in the a))sence of demand f(n- this mineral ex- ploitation has not been prosecutcnl. Roclnj jMiiaiifain nigion. — The section of the country which may be considered as the liocky Momitain region has a number of important deposits of iron ores and all the general classes of ores are found. In Avhat might be called the distinctively mountainous section, on the western slopes, magiK^tites are ol:)taiued, and some deposits of apparent magnitude are known to exist, but owing to the high elevation of the deposits and the amount of snow encountered, they have not l)een ex- ploited. It is possilde that the increasing demand for iron ores may encourage development. The iron ore deposits at Sunrise, Laramie coimty, Wyo., are quite extensi\'e; until late years, however, but little ore had been prochu-ed from them. The ore is a, red hematite occurring in carlK)iHfei-ous lime- . _f .■ ■•■ m^ 1^ .■ ^ ^ •I wm^ , ^ .. , •■'■. -'i^s;,':' '^"^ -V.:' • - i ■ ^^W^Y' ; , ^.;/;:r^*^^^^^"' ■«■' 1 ■ A ■ '',;-■ „ '.V ,,■ y^'^--'rf M' ■ "^^^^^fcl^ ■ "-'*«»* -* ■*- , J" .',..- , I .'^*^^^H^^^^^ rV i*- ,;. ■ :r1^ " ^/.^jg^gj^ / J J^^ ■•.r-'y-yT ^_ . ^^P^Bj \ / ' " ':!•»'-- i5,5r- .'. .-Iv, ' ^'-'in^i ^^^^ .jpBHIf «.-, ■,-■■'?■ 5- '.■■ 'o. 4i #^ 2^.i^"^'^ "-'■^i- ^ PLATE X. — RED HEMATITE MINE, RED MOUNTAIN, NEAR bIRMINGHAM, ALABAMA, PLATE XL— LIMONITE BANKS NEAR TECUMSEH, CHEROKEE COUNTY, ALABAMA, IRON ORE. 415 stone; rovers, as it is claimed, a supertieial area of alxnit L>() smiare miles; contains from rtO to (17 per cent ''f iron from 2.5 to 5 per cent of silica, and is low "I phosphorus.

The view (Plate XIV) shows the (U'e hi sUii to- g-ether with the covering of limestone and earth. In New ^Mexico there is a deposit where red hematite and magnetite ores are obtained. The Fierro, or U nion Hill, and Jim Fair mines are located in the territory of New Mexico, near Hanover. Mr. D. M. Barringer, ]M. E., states that the ore generally, but not always, occurs with eruptive granite and limestone, probably carboniferous, the vein being vertical or dipping at a steep angle. The ore of the Union Hill mine is a mix- ture of approximately 75 per cent luagnetite and 25 per cent hematite, and is quite hard. The ore of the Jim Fair mine is of practically the reverse composition to that of the Union Hill, the greater portion being of the hematite variety, and is also quite hard. Both here and at the Union Hill mine the ore stands in dikes, and is quarried out in open cuts. ]Mr. Barringer states that at one place there is a large deposit of brown hematite ore, and at one point there is also a consideral)le amount of specular ore. l^he ore carries satisfactorj^ percentages of iron, and is of Bessemer quality. The permanency of this deposit does not seem assured from the results of mining- operations to date. In the San Luis vallev of Colorado, which may be said to be in the heart of the Rocky mountains, lirown hematite ores are mined, and one mine has been phe- nomenal not only for the quantity taki-n fr(jm it, but also for, the low percentage of phosphorus in the ore. In fact, the product has been persistently a Bessemer ore, and it is probable that no other deposit of )>rown hematite has produced as much low phosphorus ore as the Orient mine. This mine is located in the eastern part of Saguache county, Colo., about eight miles from Villa Grove, and was opened in 1882. The ore l;)ody is from 30 to 150 feet in width and is worked by means of tunnels, from which stopes are run. Over 1,000.000 tons of ore have been obtained from this deposit, but unfortunately it shows signs of exhaustion. It may be, however, that deposits of similar character will l)e found in the same district. Plate XV is a view of the Orient mine, showing one of the inclines from which the ore is loaded onto cars for transportation to the l>last furnace. Between the Pacific coast and the Rocky mountains there are a numlier of deposits of iron ore, but few have been exploited, because there has been little or no market for the mineral. Blast furnaces which were located at Ogden, Utah, at Clipper Gap, Cal., and at Salem, Oreg., have ceased operations, and th(> only enterpi'ise now active is near Port Townsend, on Puget sound, in the state of Washington.

Iron ore deposits in the United States vary materi- ally in character, size, and occurrence, and the geolog- ical and physical conditions of the several varieties generallv known as magnetite, red hematite, brown hematite, and carbonate oi-es require different methods of exploitation which also vary greatly. The known character, the apparent dimensions, the general form, and the position of an iron ore deposit, with reference to the surface and water, the physical structure or chemical composition of the material to l>e extracted, the character of the earth or rock inclosing or occurring in the ore body, the stratification, di]), and strike, tlie simplicity or complexity of the ore Iwdy. the conven- ience of the deposit to an available market for its pro- duct, tuid the capital at command of those 5vho attempt the exploitation all influence the metliods followed in mining ii'on ore.

In the Mesal.)i range of Minnesota, in the Sunrise district of Wyoming, ;ind in a number of brown hema- tite deposits of the South, large open cuts are worked by the use of the steam shovel, these ai^jaliances remov- ing the ore in successive benches after large areas have been stripped by the same method. Where the body of ore is under consideral:)le cover, if the roof is firm, or if the vein matter is comparati^•ely ntirrow and the dip steep, it is removed through shafts, either vertical or inclined, and through tunnels or adits. In a number of instances open cut work has, after reach- ing a considerable dejath, been supplemented by under- ground exploitation, while in a few cases this method has been reversed and a large open cut has supplanted underground work. The shafts or adits, which are gen- erally expected to serve as long as the deposit yields ore, are necessarily cost!}" and need to be planned and located witli care, for tlwough these the miners have iiccess to the underground workings, and the ore and water are ctirried to the natural surface. Except when the strata penetrated are exceptionally compact ;ind hard, the shtifts or adits must be sub- stantially timbered, so that they can be maintained until the deposit is exhausted; they are excavated either in the ore or in inclosing rock, and if in the ore large 418 MINES AND QUARRIP]S. bodies are left adjacent to these avenues of approaeh as a safeguard against accident. From these main arteries drifts are opened either parallel or at different angles in wide or shallow deposits, or at determined depths in narrow and deep deposits, and from these in turn supplementary' drifts are run and rooms or stopes excavated. In deposits dipping considerably from the horizon one prevailing method of exploitiition is to open a series of drifts at different levels, from which mining is carried on simultaneousl}' ; the upper levels are farther advanced than those below, the oi'e being taken out in horizontal sections or slices, known in mining parlance as stopes. When the ore is worked above a given level and allowed to fall b}' gravit}^, through chutes or otherwise, to vehicles which deliver it to the main arteries, the method is called " overhand stoping." Where the material is attacked below a level and the ore raised to this level, the method is recognized as "underhand stoping." The overhand system is, under most circum- stances, the cheaper and more advantageous, but the underhand stoping is necessary in taking up floors, removing pillars, and in some open cut work. In underground operations the space made void as the ore is removed must be protected, at least in part, either by timbering or by filling in rock or other waste material. In some instances the ore, if hard and if left in pillars alternating with rooms or stopes, will safely support the roof, but often the proportion of ore sacri- ficed is too great to make this method desirable. After shafts or adits have been sunk and main drifts run the ore is taken out by various systems, which may he briefl}' designated as follows: " Milling," in which the surface earth is removed and the ore drawn through "raises" into drifts located some distance below the top of the ore, thus making large sinks or craters. This system requires that the cover be stripped, and is especially adapted to niodcr- ately shallow deposits of soft ore covering a large area. In "caving" a series of levels connecting with the main shaft or with several shafts are sinuiltancously worked, the ore being taken out h-»m the upper levels and delivered through winzes to lower levels which are protected by the ore vn situ. As the ore is removed from the portion of one level the superincumbent rock or earth is allowed to cave upon the ore below, and fre- quently the settling of the material is facilitated ))y the use of explosives. By this method but little ore need be left in a deposit, and if care is exercised tlie risks are not great and but little waste becomes mixed with the ore. This method is applied more to soft or mod- erately soft ores than to those whicii are harder, but it is used in some hard ore mines where the roof or hang- ing wall is insecure. "Drifting" is employed in all underground mining, but where a series of parallel drifts, one advanced more than another, are employed to slice off the deposit the method is specifically known as the "drifting or slicing system." " Room mining" may be considered either as digging out cavities which alternate with pillars, or as opening cavities of considerable length, width, and height, usu- ally from foot wall to hanging wall, and supporting the last named and the roof by an elaborate arrangement of timbers known as square sets, in which the timbers are so placed as to form the outlines of a series of cubes resting upon one another by carefuUj' fitted joints. This method is largely employed in removing soft hema- tite, and some of the cavities thus made and protected are of enormous size. "Filling" is not so much a method of mining as a means of protecting the workings by depositing in the cavities waste rock, sand, and other refuse. This method is often more economical than timber support, and is adapted to hard ore mines. The magnetites, as a rule, are found in fairly well- defined veins, inclosed between walls and dipping at steep angles from the horizon. Some of these veins are of enormous size, as in the Lake Champlain district of New York, where the texture and hardness of the ore permit of its use as pillars in the mines. Other veins are narrow and tortuous, although persistent, and each of these characteristics demands different methods of exploitation. Where magnetic iron ore is obtained from under- ground operations the ore left as pillars generally fur- nishes sufficient support for the roof. There have been instances where the proportion of the total ore in the deposits which these pillars represented was so large, or the tendency of the mineral to break from the pillars in large masses was so great, as to cause their abandon- ment. FINE ORES. During late years there have been interesting discus- sions in the technical press concerning disturl)ances in blast furnaces, which are attributed largely to the increasing use of finely comminuted iron ores. The ti-oubles have been emphasized by the contemporaneous development of the JMesabi range in Minnesota, where a majority of the ores occur finely comminuted, some practically as powder, by the use of concentrated ores, and by the increase in the dimensions and power of blast furnaces. As a result, fine ores have been dis- credited, and explosions, slips, and losses in the blast furnaces have been attributed to the use of these ores. Fine ore is undoubtedly more troublesome in the blast furnace than ore which is of moderate size, as the com- minuted material is liable to sift down through the charge and accumulate in portions of the furnace, in- creasing the resistance of the blast, and a portion as flocculent material is carried over with the furnace gases. In some blast furnaces the latter represents so large a proportion of the ore charged that the material .Ki^iM- f PLATE XIV.— SUNRISE PIT FROM THE EAST, AT SUNRISE, LARAMIE COUNTY, WYOMING. PLATE XV.— NOS. 3 AND 4 TRAMS AND RAILROAD TRACKS, ORIENT MINE, NEAR SALIDA, SAGUACHE COUNTY, COLORADO. IRON ORE. 419 is recovered and formed into briquettes, or made into mud with water, to be returned into the furnace. There is no intention to question the desirabilit}' of using relatively coarse ores in blast furnaces, but it is probable that fine ores are blamed for some disturb- ances for which they are only partially responsible. The accumulation of tine material of any kind in a por- tion of a blast furnace may cause unequal settlements, slips, or irregular operation, and, while the tine ore is subject to this, the same results may come from an accu- mulation of comminuted coke and fluxes. In the en- largement of blast furnaces the system of feeding- materials has been radically changed. Where thousands of tons are fed daily into the throat of a blast furnace, the handling of this becomes an important matter, and labor-saving appliances are demanded. A few j^ears ago the general practice of blast furnaces, of what was then large size but would now be considered of moder- ate dimensions, was to discharge the raw material from car.s running upon trestles, shovel or fork this into charging buggies which were elevated to the top of the furnace and discharged upon the bell, which closed the throat bj" fitting against the hopper. But where large quantities are daily handled bins have been introduced which take the place of trestles, and the material, in- stead of being shoveled or forked into the discharging buggies, drops from railroad cars into bins and from bins through chutes into scale or weigh cars, thence into skip cars, which are lifted considerahlj' above the top of the furnace and dumped into the receiving hopper, thence through a bell and chamber to the main furnace bell. Bins have been erected to considerable height, and in dumping the material, particularly coke, into the bins, or in passing it through them, it becomes more or less broken. At some furnaces the coke bin discharges immediately into the skip car running to the top of the furnace, but in a majority of cases the weigh car inter- venes. As a consequence, a large percentage of coke is ground to powder, for it may have an aggregate drop of from 30 to .50 feet from the time it leaves the car in which it is transported until it touches the main bell of the furnace. In the smelting operation there is no opportunity for coke to be consumed until it approaches the tuyeres of the blast furnace, for it is liere that the combustion of the fuel is made possible by the admission of heated air. An excess of free oxygen woidd carry this com- bustion to a point which would result in imperfect and irregular furnace operation, conse(iuentIy the fine material which may accumulate in the shaft or upper portion of the furnace may be added to until it is in such volume and position as to cause a disturbance b_y slipping, resulting in increased pressure of blast, and an irregular working of the blast furnace. While the same may be true of the line ore, this has the advantage of being reduced by the gas(>s resulting from the com- bustion of the fuel. Investigations of some of the larger furnaces blown out for repair seklonj show unre- duced ore, although the proportion of hne ore fed may have been large, but indicate volumes of coke dust adjacent to the walls or accuuudated in different por- tions of the blast furnace. The combination of hne ore and fine coke may therefore be considered largely' responsible for many slips and irregularities, but it is possible that explosions which have been so severe at a number of furnaces are attributable primarily to floc- culent incandescent carbonaceous matter (resulting from the grinding of the coke), meeting oxygen under conditions similar to those in coal mines, flour mills, and grain elevators. The quantity and chemical character of the fine ores which are available demonstrate the necessity of their use, and it is the duty of those designing or operating blast furnaces to provide for such utilization, and where satisfactory operation is secured under disadvantage the manager of a plant is entitled to proper credit for overcoming difficulties. The constructor must take into consideration the handling and distribution of this material, and also design and equip the furnace to meet the excessive pressure or unequal settlement which may be traceable to the tine ores, whether associated with fine coke or not. The latter condition will exist to some extent in any furnace, although for the reasons given above the quantity of fine coke is undoubtedly greatly magnified in the recent method of handling the materials. Ores which cost at the furnace 5, G, or more cents per unit of metal can not be wasted with impunitj', and where it is found impracticable to control the loss of fine ore through the gas flues, the collection of these, and their preparation for subsequent treat- ment, demand attention. The briquetting of fine ores, whether in their natural state or after beneficiation, is also conmianding attention. Whenever an iron ore is handled and rehandled, passed through any mechanical apparatus, or heated, there is additional cost placed against it, and this cost will naturally afl:ect the price of pig iron. However, it may be assumed as an axiom that the treatment of ores preliminary to their lieino- fed into the blast furnace can generally be considered as more economical than depending on the furnace to do the work. Methods of cheaply beneficiating and briquetting fine ores so as to introduce them into the blast furnace, and permit of their being carried down into the zone of reduction l)efore changing form, seem to present a pos- sible feature of advance, to which those interested in the smelting of iron can well aft'ord to give attention. While fine ores are considered l>y many manao-ers undesirable, there is also objection to the mineral being of large size, especially in dense magnetites or red hematites. Preliminary t'rushing to approximately uniform size is therefore desirable, and to meet fur- nace requirements largo crushing plants are in use at 420 MINES AND QUARRIES. some important mines, the purpose being to reduce the hard ores to sizes convenient for handling and adapted to quick reduction. COKt'EKTRATION OF IKON ORES. In various parts of the country there are deposits of iron ores of considerable magnitude in which the amount of metallic iron is insufficient to justify the mining of the mineral and its use in blast furnaces. Some of these deposits are located so that the ore can })e cheaply mined, and are also convenient to transportation facili- ties to market. To reduce the percentage of gangue and to produce material carrying iron sufficient for economical smelt- ing, these ores need to be beneticiated, and usually they are comminuted by crushing or grinding if the}' are not naturally of a size suitable for the purpose. After reduction in size the ore is either passed through jigs, where in connection with water the iron oxide separates from the gangue by specific gravity or the fine material is delivered to magnetic separators. The separation in jigs is effected when the specific gravitj' of the iron oxide and the gangue differ sufficiently to permit of a good separation. In magnetic separation the magnetic particles are attracted to belts, drums, or to stationary magnets and the gangue or such portion as is feebly magnetic is rejected. In either process time and the degree of comminution are elements in securing satis- factory results. Magnetic separation is confined to the treatment of lean magnetic ores or to hematites which are made magnetic by preliminary roasting, although some of the apparatus used discriminates satisfactorily between minerals of moderately different magnetic qualit}'. The size of the grains of ore intermixed with the gangue determines the possibilit}^ of perfection being- approached by either system of concentration. But in many ores these grains are so small that the connniini- tion required adds greatl}' to the cost, and also produces material whose desirability for smelting purposes is limited. Consequently, most of the concentrating plants do not attempt to attain perfection in separation, but produce a concentrate which, while l^elow the possible standard of puritv obtainable, is acceptalile to the blast furnace managers because of the size of the grains. It is found to be advantageous to lose a portion of the min- eral in the tailings rather than to attempt perfection with the separators. In some cases the tailings, when practically free frcnu iron, are re-treated because of thi; value of these bj^-products. Tlie sand resulting from a siliceous ore finds a ready sale, and the apatite sepa- rated from high phosphorus magnetite is in demand for fertilizing. The magnetic separatoi's in use in the United States in l'.)02 produced 11)2,285 long tons of commercial ore. Most of this \va~ miejnrtite Drc. In additif)n a cobbin'j method was used, wherein ore of considerable size was treated by magnetic separators. The possibilities of producing an ore rich enough for smelting purposes from some of the large deposits of lean magnetite have encouraged the introduction of a number of forms of separators, only a few of which, however, have proved of sufficient economic importance to be used. ROASTING IRON ORES. Among the methods used to beneficiate iron ores — that is, to improve their natural condition — is roasting, which ma}' be applied for several purposes: 1. To drive off' moisture. 2. AVhile driving off' moisture, to bake so as to sepa- rate the earthy matter which adheres to some ores and which often carries a large proportion of silica. 3. To eliminate carbonic acid, as in the case of the treatment of carlionate ores, thereb}' practically con- verting carbonate into Vjrown hematite. i. To reduce the percentage of sulphur carried in many ores, particularl}- magnetites. 5. To break up dense ores or make changes in the degree of oxidation and thus increase their reducibilit}'. Roasting was formerly done entireh' in open heaps, formed of layers of wood (in some cases charcoal or tine bituminous coal supplementing the wood), alternat- ing with layers of ore. These piles, when fire was applied to them, burned for months, and, in fact, the pile after being completed at one end was extended, while the end first finished was being roasted and the roasted ore taken from it to the furnace. An improve- ment in roasting was the introduction of cylindrical or rectangular masonry or metal kilns, in which fuel is mixed with the ore. In this way a more economical handling of the material is possible, and the results are under better control. In later years improvements in the roasting of ore have been practically confined to f(M:>ding kilns with gas, dei'ived directly from the gas furnaces or obtained from gas producers. In the dr}-- ing of brown hematites advanced progress is illustrated at the Shelby Iron Works, Alabama, where the Davis- Colby kiln using gas, roasts brown hematite ores. A statement by Mr. Charles J. Christian shows that tak- ing green ore as it came fi-om the washer, the yield was i?) per cent, and to ff ux this ore 23 per cent of limestone was required, while to smelt it 135 bushels of charcoal were necessary. When roasted in heaps, the moisture driven otf, and the reduction of silica, which was obtained by screening, showed a yield of 50 per cent of iron, the I'cquirements for smelting being 20 per cent of lime- stone and 1((5 bushels of charcoal. When gas kilns were introduced the yield of the ore was increased to 5S per cent, the proportion of fiux was reduced to IS per cent and the fuel consumption to K)^ bushels of charcoal. An experiment was also made in taking from a stock pile ore which had been i-oasted in heaps a-id reroast- DIAGRAM 1- CLASSIFICATION OF IRON ORE PRODUCTION: 1889 TO I902.

When the yield was increased to 56 per cent, the flux M'as reduced to 15 per cent of the ore burden, and the fuel consumption fell to 95 bushels of cliarcoal pt'r ton of iron. Inordinary practice, Mr. Christian states, that the shrinkage of ore due to roasting and screening- is about )>:', per cent, water to the extent of 15 to IS per cent being driven olf; the balance is tailings in which ther(^, is some iron, but this loss is more than com- pensated for by the reduction in silica. The richer ore not only requires less flux and fuel, but also increases the product from a given furnace and reduces the cost of production correspondingly. In roasting for the elimination of carbonic acid, most of the ores have been treated in piles, although some have been subjected to the roasting process in large kilns, some of these being 16 feet in diameter and 60 feet high; it is probable, however, that better results would be obtained m lower kilns. This treatment of the roasted ore is primarily to convert the carbonate into sesquioxide of iron by driving ofl' the carl)onic acid gas, and practically converting the clay ironstone ore into a brown hematite ore. A number of years ago efl'orts were made in Scotland to use the upper portion of a blast furnace for this pur- pose, and one plant was erected in this country, the ex- pectation being not only to drive off the carbonic acid gas from the ore, but to coke the raw coal as it passed down the furnace. This departure need not be further considered, as practically all the roasting is now done prior to feeding the ore to the furnace, and the results obtained encourage the continuance of this practice. When sulphur is to be eliminated, the old practice of feeding solid fuel with the ore to heaps or kilns is less perfect than the new, as in the newer kilns using gas the ore is maintained at a high temperature, so as to oxidize more of the sulphur than would otherwise be the case. The most extensive use of ore roasting kilns is in the neighborhood of the Cornwall ore mines, Pennsylvania, where the average amount of sul])hur in the ore as mined is 2.5 per cent. In kilns operated by fuel fed in alternate layers with the ore the sulphur is reduced about one-half; but in the kilns where gas is applied and the incandescent ore subsequently sub- jected to currents of air, the percentage of sulphur is reduced lielow 1 per cent. In addition to reducing the sulphur, the ore is improved in texture, and results ob- tained at the Wharton furnace in New Jersey show a very decided improvement independent of the elimi- nation of sulphur. The roasting undouljtedly affects the physical character of the ore, making it more por- ous; it is, therefore, more readily attacked b_v the ))last furnace gases. Where a component is to Ije eliminated in whole or in part, the driving off' of this, whether it be water, carlionic acid, or sulphur, affects the texture of the mineral and makes it more readily reducible. It may be that the combined water in a magnetic ore, or the proportion whicii is hygros(^opic, removed in the pi'ocess of roasting, improves the texture of the ore; l)ut this is not a matter upon wliicii enough experiment has been made to speak with detiniteness. Mr. Edward Kelly, manager of the \\'harton blast furnaces in New Jersey, states that the base of the ore mixtui-e used in these furnaces is Hibernia magnetic ore, a close grained refractory ore, which is roasted to secure lower fuel consumption than is necessary when using it in the raw state. One furnace using 75 per cent Hiber- nia roasted ore, 12.5 per cent Hibernia raw ore, and 12.5 per cent soft Lake Superior liematite (the yield of this mixture approximating 50 per cent of iron) pro- duced a ton of pig iron on a fuel consumption of 2,050 pounds. Another furnace, using 75 per cent Hibernia unroasted ore and 25 per cent of hematites, required 2,500 pounds of fuel to make 1 ton of metal. There- fore, the apparent saving at the furnace using Hibernia ore roasted is 450 pounds of fuel per ton of metal. With fuel at §4 per ton, this represents a saving of 90 cents per ton of pig iron, which the management at- tributed entirely to the roasting of Hibernia ore. It may be considered as an established principle that whenever the metallic yield of an ore can be improved and the cinder making constituents reduced and j'et left in sufficient quantity to permit satisfactory smelting, such a treatment is more economically done before charging the ore into the furnace than after it reaches the tunnel head, and it maj' be asserted that the bene- ficiating of ores in a blast furnace is the most expensive method to follow. To determine the results to be obtained from roasting an iron ore a practical demonstration is essential. A laboratory test will be of value, but not nearlv so satis- factor}^ as a practical trial in a blast furnace. However, as such a trial is expensive, the laboratory experiment must be relied upon where there is no roasting appli- ance. Thus, by taking a sample of unroasted ore, crushing it fine, and similarly treating a sample of the same ore roasted, exposing this in tubes to the action of furnace gases, or of a current of carbon monoxide gas at a low red heat, the amount of oxygen in each case removed could be compared. Such a test would indicate whether a saving in fuel to offset the expense of roasting is pi'obable. Blast furnaces using raw Lake Champlain magnetic ores require from 2,6(i0 to 2.S00 pounds of fuel per ton of metal, and in similar furnaces using Lake Superior ores 2,000 to 2,200 pounds per ton are re((uired. With coke at $2.25 per ton the fuel saving of 601) pounds repi'esents a decreased cost of 67.5 cents per ton of pig iron. When magnetites are roasted the smelting conditions approximate those pre- vailing with red hematites. Another feature whicli has attracted attention in the Lake Superior region is the amount of moisture in the ore, and the proposition has been made to experiment 422 MINES AND QUARRIES. on a large scale with the idea of reducing this, a.s it limits the yield of the ore in the furnace and means additional freight by vessels tu the lower lake and froui the receiving docks to the Mast furnaces. ADVANTAGES OF MIXING IKON ORES. The circumstances surrounding the mining, hand- ling, and transporting of ores from the Lake Superior iron region seem to have a decidedly beneficial influence in securing the delivery to the blast furnaces of ores of nearly uniform composition. Similar conditions pre- vail elsewhere, but not to the same extent as in the Lake Superior region, because of the size of the de- posits in that district, their liberal exploitation, their distance from points of consumption, and climatic con- ditions which limit the water transportation of ores. All iron deposits vary more or less in different por- tions. This variation may be in the percentage of iron, silica, phosphorus, or other ingredients, and where a furnace depends on local mines, drawing upon them from day to day, receiving its stock practically as mined, greater irregularities are to be expected in the ore de- livered than where ore passes through various handlings. In the Lake Superior region the practice of the larger mines, although the mineral may nominally be of uni- form character, is to win ore from sevei'al portions of the deposit simultaneously. The ores so won may be mixed in trains going to the ore docks, or trains may be made up entirel}' of ore from certain portions of the mines. Unless the chemical composition of this ore varies notably in the percentages of iron and phos- phorus no segregation is necessary, and a number of bins in the shipping dock are tilled with ore as it comes down in the railroad trains. A vessel brought to the side of the dock receives ore simultaneously, or nearlv so, from a number of alternate pocket spouts, and is then moved to intermediate spouts. As the bins or pockets hold several carloads each there is a mixture in these and a further mixture-, in the hokl of the vessel. When the vessel reaches the receiving dock the ore is taken out b}" mechanical appliances, seldom liy hand, the buckets delivering the ore either to stock piles on the receiving docks or directly into cars which conve}' it to the blast furnace. As the shipping season on the Great Lakes covers usually about seven months in each year the ))last fur- naces must either carry stocks of ore at the phints or have them held at the receiving docks. Such accumula- tions of stocks result in securing a general mixture of ores from each mine which supplies the plant. Where work is prosecuted in the winter in the Lake Superior region, it is confined principally to dead work or ex- ploration, largely to opening up drifts or chambers to facilitate mining during the next season. This ore taken out in the winter becomes thoroughly mixed in the stock pile and is subject to the same handling as above described. Even if the ore is delivered from ves- sels directly to cars, and these cars are dumped into the bins at the blast furnace, there is the admixture of ore from different parts of the mine, resulting from hand- ling at the shipping and receiving docks, a mixture which it is not possible to secure from ores which are mined and sent directly to the furnace. The result is that the Lake Superior ores from different mines natur- ally have greater uniformity than those from other sec- tions which maj'' have ores of equal desirability. This may seem an unimportant matter when the avei'age of the ores charged determine the basis on which to use them, but it exerts an effect on the operation of the furnace because there may be constant changes which affect the fluxing. For if at one time of a day the ore is low in silica, and at another time comparatively high, although the ore comes from the same bin, the fluxing will not be as perfoctl}' equated as desired. As a con- sequence, the interior lining of a blast furnace is at- tacked, or the pig iron produced is more irregular than if the same relation between the gangue material in the ore and the fluxing medium was maintained steadil}'. CLASSIFICATION OF IRON ORE PRODUCTION. The rapid growth in production, both absolutel}' and proportionately, of red hematite in the United States is illustrated by Diagram I, which shows proportionate!}' the quantity of red hematite, brown hematite, mag- netite, and carbonate iron ores produced in 1889 (the classification being that of the Eleventh Census), and from 1890 to 19(i2, inclusive. While there has been a decided increase in red hematite, there has also been an advance, aljsolutely l)ut not proportionately, in brown hematite, and a decline in the proportion of magnetite, although in late years this has been nearly stationary. The (juantity of carbonate ore has con- stantly decreased. Diagram II gives the relative quantities of each class of ore supplied by the more important producing states for the three census years 1880, 1889, and 1902. The illustration does not embrace the stat,es producing small quantities. Even if the year 1900 had been se- lected for the comparison, the growth over 1889 would have been shown to be almost as great as that of 1889 over 1880. The increase of 190'i over 1889 is greater. The plate shows that the entire production of Min- nesota, and nearly ail of the output of Alabama, Michigan, and WisconsiTi, is classed as red hematite. It also shows the advance made in thirteen years, which is most notable in Alabama, Michigan, and Minnesota. The majority of the brown hematites are indicated as being mined in Alabama, Colorado, Geor- gia, Penn.sylvania, Tennessee, and the Virginias, while the magnetites come principally from New Jersey, IS'ew York, and Pennsylvania.

PRODUCTION OF IRON ORE IN LARGE MINES. The juoportion of the output of the United States contriliuted by large mines is a matter to which atten- tion has been drawn, and Diagram III is presented to illustrate this. Data are not at hand showing the num- ber of large mines and their total output, except for the years beginning with 1892, but the total production is given for the census years 1850, 18H0, 1S70, 1S8(I, and 1889. The full lines of the column illustrate the total production of the ore, while the shaded portions show the cpiantity contributed by mines supplying over 50.000 tons. The total number of the larger mines in each year since 1891 appears in numerals at the sides of the respective columns. This showing demonstrates that while there has been an increase in the output of the smaller mines the bulk of the augmented pi-oduct is due to the larger mines.

Although manganese occupies an important position among metals, and is necessary in the manufacture of steel, of glass, and in the chemical industry, tlie pro- duction in the United States is small; and in 1902 may properly be discounted to the extent of '.t,(J()() long tons reported as mined in Montana, which was not imme- diately available for consumption. Table 1 is a comparative summary of the statistics for the industry as reported for the years 1902, 1889, and 1880.

In the year 1902 the data are given in full, but for the previous census years some details are unobtainable, and in the year 1880 there was 1 mine from which no information was secured except the production of ore and its estimated value. Of the 19 mines reported in 1902, 3 were in Califor- nia, 6 each in Georgia and Virginia, 2 in Arkansas, and 1 each in Montana and South Carolina. The entire number was controlled by 19 operators, of whom 8 were individuals; 5, firms; and 6, incorporated companies.

In 1889 the inquiries in regard to capital were dif- ferent from 1902, the capital invested in lands, build- ings and fixtures, machinery, tools and implements, live stock, cash, and stock of ore on hand being asked for at that census; therefore no comparison of anv value can be made. According to the reports made in 1889 the total amount of capital invested was $2,188,950, divided as follows: Land, $1,618,650; buildings and tixtmes, $98,700; machinery, tools, etc., $233,750; other items, including cash, $237,850. EriijAoyees and imges. — In Table 10 the statistics of employees and wages are presented in detail by states. The different classes of salaried oflncials and wage-earn- ers are given. Of the total amount, $81,319, reported as paid for salaries and wages in the production of manganese ore, $74,924, or 88.9 per cent, was paid to wage-earners, and $9,395, or 11.1 per cent, to the salaried officials, clerks, etc. (43.5) a:m\ MINES AND QUARRIES, Table 10 .show.s also the avenio-o muui)or of wag'c- earners at specified daily rates of pay l)y oceupations. Miners constituted 41). 5 per cent of the total number of wage-earners, and of all miners 80.2 per cent Avere em- ployed at rates from $1 to $l.-2i per day. This lo^v wage rate was due to the fact that most of the employees were unskilled, and the wages paid in the Southern states were loAver, as a rule, than tlios(> prevailing in the Lake Supeiior region, where the climatic condi- tions are more severe. Of the !."> engineers, >\ recei\-od $2 or more per day. jMiners' helpers formed a small class, constituting 1.5 -pn' cent of the total wage-earners. The class of "all other wage-earners" numbered 5(1, composed chiefly of ordinary laborers. Of these work- men 92.9 per cent received from §1 to $1.21 per day, the same general rate as that of many of the miners, while 7.1 per cent received $1.25 or more. The average number of wage-earners, men and l)oys, employed during each month of the year, is also shown in Table 10. With the exception of the mines in Georgia, where employment was practically constant, the average number of wage-earners \aried consider- abl}'. It will be noted that during the summer and fall months the average numl)er of wage-earners in \'irginia was considerably augmented, falling ofl' during the win- ter and early spring months. In California the opera- tions practically closed in August and remained in this condition until the end of the year. For the various mechanical operations requiring power at the mines there were 11 steam engines of 35-1 horsepower.

Russia has for years been the largest producer, the bulk of the ore coming from the Caucasus region, the mines being located in the Secharopan district of the gov- ernment of Kutais, not far from the extreme eastern shore of the Black Sea, near Poti. India has impor- tant deposits which have been actively exploited in late years, most of those from which shipments are made being located in the presidency of Madras. In the year 1902 Brazil, where the manganese industry has been lately developed, took third position: most of the ore mined being obtained in the Minas Geraes and Naz- areth districts, located in the states of Minas Geraes and Bahia, respectively, in the eastern central portion of the country.

The value of ore at the mines would be prac'sically the price obtained for the oi-e delivered in the Pittsburg dis- trict, as al)ove, less transportation charges. In the manufacture of steel for various purposes and by different methods, the metallic manganese required ranges from about i» to 40 pounds per ton of ingots pro- duced, the average for the entire steel industry approxi- mating 20 pounds of metallic manganese, or about 25 pounds of high-grade ferromanganese per ton of ingots made. ILnujoiiifi'ivufi iron ores. — In addition to the true manganese ore produced, considerable quantities of manganiferous iron ore are obtained in the United States, the statistics of which are included in the report on iron ores. In the yeai' 1902 there was obtained in the state of Colorado 13,27;") lonff tons of this class of ore, in which the percentage of manganese varied from 18 to 32 Y^ev cent, having a total reported ^alue at the mines of $ri2.371. This ore was all used in the produc- tion of spiegeleisen at steel works and should properly be classed as manganese ore, but owiny to tlie im- possibility of segregating the proportion of wage- earners, wages, and other expens(>s chargeable in the different mines from which this ore was obtained, the (lata were included in the statistics of iron ore. In the Lake Superior regi(jn, also, consideral)le amounts of ii'on oi'e are won whidi carry small percentages of manganese, but. a>> a ride, this does not exceed 1 per cent. In X'irginia, too, a small quantity of manganif- erous iron ore has been secured while mining true manganese ore.

Argent'/fei'Dus manganlfeiritix iron oren. — In the state of Colorado argentiferous manganiferous iron ore is obtained from precious metal mines. Thi.s ore, con- taining an insufficient quantity of silver to make it \'a!uable on that account, finds a ready market as a flux for use in smelters. The ores which are mined chieliy in the vicinity of Leadville, Colo. , are classed usually as carbonates, sulphides, oxides, and siliceous ores. The first two classes are dependent for their value upon the carbonates and sulphides of lead and silver, but the oxides and siliceous ores maj' or may not be dependent on the precious metal content, and unless the value of the ores for smelting purposes was greater than the charge for the extraction of the precious metal (approxi- mating ?12 per ton) they have been considered as iron ores and included in the report on that mineral. The total quantity of these ores (which contain varying per- centages of manganese) mined in the year 1902 was 194,132 long tons, valued at $9<»8,098, an average of 14.68 per ton. In 1889, 64,987 long tons of argentifer- ous manganiferous ores valued at $227,4.55, were mined in the United States, the average value being $3. .50 per ton. This shows an increase in 1902 of 129,145 tons, or nearly twofold, while the average value per ton rose to $4.68". Manganiferous sine ores. — The frankjinite mines, located in northern New Jerse}', produce ores which carry, in addition to the zinc content, iron and manga- nese. The clinker resulting from treatment for the removal of zinc is utilized in the production of spiegel- eisen. The quantity of this class of material produced in 1902 was 65,246 long tons, valued nominally at !?1 per ton. I'hc production in 1889 was 43,648 long t(jns, valued at $54,560, or an a\'erage value of $1.25 per ton. A resume of the useful minerals profluced in the LTnited States in 1902, which contained manganese in notabk' proportions, is given in the following state- ment, in which the figures for the year 1S89 ha\'e been included for purposes of comparison: Ufii'fal,)n'nitn'(ih pro'liireil i-oiituhdiKj man/janf^.^e in nolfthlf projtorltoii.'^: 1902 iind hW9. 1902 188» Quan- tit.v (loiig tons).

EKVIEW OF THE IXDU.STRY BY STATES. The conditions surrounding and afiectiiig the pro- duction of manganese ores in different states are sum- marized as follows: Arhrnms. — Manganese ores occur chiefiy in two dis- tricts of Arkansa.s — (a) the Batesville district, in Inde- pendence and Izard counties, in the northeastern part of the state; and (b) in the southwestern section, extending from Pulaski countj- on the east to Pope couutj' and Indian Territory on the west. The mining in the latter district has been limited and practically all of the ores mined have come from the Batesville region, where they occur in residuary clays, derived from the decay of limestone. Ore was discovered near Batesville alioutl84t>, and in 1850 small quantities were sent to Boston, New York, Philadelphia, and Chicago. The maximum output was in the j^ear 1892, when 6,708 long tons were produced. Lately, however, there has been a marked decline, for although some of the ores of Arkansas carry satisfac- tory percentages of manganese, their high phosphorus content, in addition to the di.stanc-es from points of con- 440 MINES AND QUARRIKS. (sumption and tlu' expense of niinino-, has rendereil the winning- of many of them unprofitable. In ly02, 82 tons of manganese ore were secured. According to the Eleventh Census the amount of man- ganese ore mined in Arkansas in 1889 was -i.O^S tons. The total production of the district from 1850 to l'.K)i>, inclusive — some of the figures being estimate's — was 49,974 tons. (Mifornla. — California contains a number of deposits of manganese ore, some of which are reported as of high quality, and have been largely employed in chlori- nation works for the reduction of gold ores. In 19(i2 deposits in Alameda, San Joaquin, Santa Clara, and Stanislaus counties were operated, the amount produced being 84H tons. The quantity mined in 1SS9 was oH tons. The total production of manganese ore in Cali- fornia from llsT4 to 1902, inclusive, as near as can be ascertained, amounts to 11, .3.58 tons, the production in 1902 Ijeing the maximum. Colorado. — A large amount of iron oi'e, which con- tains a mixture of iron, manganese, and the precious metals, is produced in Colorado. The greater portion of this ore, which carries an insufficient amount of the precious metals to make it valuable on that account, is used as a flux in smelters, while some of that which is higher in manganese content is forwarded to steel works, where it is utilized in the manufacture of spie- geleisen. The figures for the production of these classes of ores, which ha\'e been included in the census report on iron ores, are inserted here as an item of interest. The comparison of the production inthej'ear 19()2 with that of the census year 1889 is shown in th(> following- statement: Pi-t)ihtrtiijii of iiiitii'inniffrnti>i urt-A 'in t 'n/oraral 207, 407 VMAWZ 07 Otl2 tr<-s ii.scd for yiruducjiig spie^d- Manganiferous inni eiseii (_ri'or{/i(i. — The manganese ores of Georgia iire won from two districts -thf Cartersville district, located near the town of that name in Bartow county, and the Cave Springs disti-ict, in Floyd and Polk counties. '1 he deposits in the latter district have been Imt little worked, nearly the entire production coming from the Cartei-sville district. The mines which were acti\'e in the year 1902 were all located there. Some of these man- ganese, ores are (jf good (jiiality, ))ut others contain com- paratively lijgh pei-centagesof ])hosphoi-usandare lower in manganese. The total amount of manganese ore ob- tained in Ceoro-ia in i IHli! was ?,J,{)\) lung tons, while in 1889 it was r).ao,S long tons, showing a d(.'crease of l.To.s tons, or 32. S per cent. The total production of this district from 18f)6 to 1902, inclusive— the output for some of the years ))eing estimated — was 91,594 long tons, the maximum production being 9,024 long tons, in 1887. Miintiiuii. — In previous years Montana has been an unimportant contri))utor of manganese ore, but in 1902 a large quantity of ore was reported as mined, but not shipped, from two deposits in this state. Although most of this will n(^t be immediatel}' available for use, the reported product is included in the statistical data. The deposits are located at a considerable distance from steel works, which are the largest consumers of this ore, and unless satisfactory rail rates are secui-ed it is doubt- ful whether this state will become an important producer in the innnediate future. Sdiifh (J(i roll nil. -As has been stated, the 8 tons of manganese ore which were secured near Greenwood, in this state, were shipped as a sample: no systematic mining- has been reported. Vii'ijinUi. — Virginia was the most important pro- flucer of manganese oi'e in the United States in 1889, a to al of 14,610 long tons being secured. Xearh' all of this came from the Crimoi-a mine, located in Augusta county, but after a few years this mine showed signs of exhaustion and mining op(>rations were suspended. It has, however, been reopened in the hope of encoun- tering new reserves of ore, and if these expectations are realized the state may again become an important contributor. The 1902 output was only 3,()41 tons. The aggregate production from 188(» to 1902, inclusive, was 191,nt;7 tons, the output <.if the year 1886, when 20,.>ti7 long tons were mined, being the maximum. Table 10 is a detailed summary of the statistics of the manganese industry for the United States, by states, in 1902. DESCKUTIVK. Manganese is not found in a metallic state in nature, but usually occurs as an oxide, carbonate, or silicate in comliination with one or more of the other elements. The oxides are the most connnon of manganese minerals, hut rhodonite and rhodochrosite — th(> silicate and the carbonate — are f rc((uently n)et. The conmiercially im- [lortant ores are the oxides — pyrolusite, psilomelane, biaunite, manganite, hausniannite, and wad — brief descriptions of which l^ollow: Pyrolusite, a pei-oxidc or binoxide of manganese (MnO.,), is of an iron-black color, giving a black streak on a test plate, with a hardness of 2 to 2. .5 and a specific gravity of 4.S to u. If i)ure, it woidd yield 0,3.2 per cent of manganese and 36.8 per cent of oxygen. It is used in the manufacture of ferromangancse, in the pr9 per cent of metallic manganese. Manganite, a hydrous sesquioxide of manganese (Mn^OgH^O), is of a steel-black or iron-ljlack color, with a hardness of 4 to 4.5 and a specific gravity of 4.3 to 4.4. When the water is removed from manganite it changes to pyrolusite, hausmannite, or braunite; in some cases the latter minerals are sujjposed to l)c altered manganite, this being especially true of pyrolusite. Hausmannite, a double protcbinoxide of manganese (MhjOJ, is of a brownish-black color and of a suljme- tallic luster, with a hardness of from 5 to 5.5 and a specific gravity of 4.7. It is a rare mineral, which, if pure, would contain 72.1 per c(Mit 9 ■> '> ■1 48 3 1 V. 53 85 12 15 53 64 12 15 53 9-2 12 15 53 98 6 53 96 6 53 114 6 53 109 6 53 113 53 102 53 131 53 141 63 ](i3 9 4 9 4 9 4 9 4 9 4 9 4 9 4 9 4 9 4 9 4 9 4 9 4 S50 S2, 915 S600 S280 SI. .575 $421 $50 Jl,310 SI 79 8280 «61 86, ,si;6 88, 691 81,210 846 3, .500 8,041 9,090 »10, 175 S20,.S3O S29, 444 8117, 462 4 - iia 192 1 Includes operators distributed as follows: Arkansas, 2; Montana, 1; Soutli Carolina, 1. LEAD AND ZINC ORE (44:;; LEAD AND ZINC ORE. B}^ Isaac \. Houkwich, Ph. D. The present report deals onl^y with mines producing nonargentiterous h>ad and zinc ores. The statistics relative to the production of lead and zinc incidental to mining for gt)ld and .silver are treated in the report on gold and silver. I'he combination of the mining and smelting of lead in earlv times precluded separate statistics for each 23rocess. The census data relating specifically to lead mining were first presented in 1870. The earliest men- tion of zinc ore in census reports was in I860, when 2 mines were reported with 52 employees and a value of product aggregating $72,600. Lead and zinc mining was reported at the census of 1870, and at the two sub- sequent censuses. Differences in the scope of the in- quiry, and in the method of presenting the results, materially impair the value of the statistics of all these years for comparative purposes. At the Eleventh Cen.sus no statistics of wages, or of other expenditures, were shown for the zinc mines of southwestern Mis- souri; only the output, amounting to 186,262.308 pounds, valued at $2,02i,057, was reported for that dis- trict. The statistics of the Eleventh Census are, there- fore, omitted from the comparative summary given in the following tab'e: Table 1. — Ciiiiijuinitive minmari/: 190 J, I8811, imd 1S70.

The total number of lead and zinc mines reported for the United States in 1902 is 559, and the total number of operators 557; the difference represents 2 incorpo- rated companies in Virginia that operated iron mines in connection with zinc mines and are included in the report on iron mines; the statistics for the zinc mines, how- ever, e.xcept those of capitalization, were segregated and are showm in this report. Because of the prevalence oi the leasing system in the operation of the lead and zinc mines, the terms "mine" and '' oj^erator" are indetinite in their meaning. The unit of these tallies represents every operation for which a separate return was made. If the land was operated by its owner, the owner's report was included in the tables. Leasing companies whose business was confined to clisti'il)uting land in small lots among oper- ators and to drawing royalties, were not included in the general tables, unless some hired labor was employed by them in developing the mines, [f the land was operated by a lessee with the help of hired labor, the lessee's report was tabulated. The numerous small sublessees, personally working in the mines, as a rule did not report; only 56 operators of that class made returns, and the (44.5) 446 MINES x^.ND QUARRIES. statistics for these are included in the ta})leis. The share and zinc production of Kansas and Missouri is shown contributed by this class of small operators to the lead in the following table: Table 3.— DISTRIBUTION OF THE VALUE OF THE LEAD AND ZINC PRODUCTION OF KANSAS AND MISSOURI BY CLASS OF OPERATORS: 1902.'

The Missouri lead and zinc mine inspector's list of mines enumerates 151 landowners; according to cen,sus returns for Mis- souri. 61 operators were owners of the lands the_y oper- ated, which leaves 90 landowners whose mines were operated under the leasing system. The above number of lessees and sublessees does not include the numerous class of small sublessees who do the work themselves with pick and shovel. The number of such sublessees reported by landowners w^as 638. of whom 632 were reported from Missouri. This numl)er. however, is very far from complete, an accurate count being pre- cluded by the shifting character of this class of miners. The unincorporated form of business organization was the prevailing form among operators. There were in all 398 unincorporated concerns and 161 corporations directlj^ engaged in operating the mines. Judged by the volume of production, the corporations held a place of greater prominence in the lead-zinc mining industry than that held by unincorporated operators. The share of each class of operators in the total pro- duction and the average output per mine are shown in the following table: T,\BLE 4. — C'laKsijicdtifiri i/f!eoil. mid zinc iiiirii'H, hi/ cliiiraclir of oii.mership: 1902.

Average values of zinc ore drawn from the preceding statement would be misleading, inasmuch as the quantity and the value of zinc ore for incorporated companies and, consetiuently, for all mines in the United States, are affected by the returns of 3 large eastern mines — 1 in New Jersey and 2 in Virginia — that produce low grade ore.

Of the 42 dividend paying com])aiiie.s whose dividends are .shown in the i^receding table, there were only 5 with hotli preferred and connnon stock; of these only 1 company declai'ed dividends on both classes of stock, while 4 paid di\'idends on preferred stock alone. The average rate of dividends on preferred stock was 3.2 per cent. The 38 companies which declared dividends on comoion stock had an authorized capitalization of 111,957,000, divided into |l(),95T,O00 common, and fl.000,00() preferred; of this the amount outstanding was §6,008,400 common and ^25,550 preferred. The average rate of dividends paid by these companies on their common stock was 10.3 per cent. The census returns furnish no data for determining the net profits earned in mining, since the excess of the value of the jiroduct over the expenses reported is not an indication of actual profit; yet some data bearing indirectly on the subject are found in the returns of the dividend paying companies. The payment of dividends by a company may oitlinarily be taken as a proof of successful operation. Cei'tainly it must not be assumed that the dividends paid during one year are derived from the pi'ofits of the .same 3'ear, nor that tlie failure to declare a dividend during a certain yeai' is an evi- dence of unprofital)]e mining. In the lirst case, the dividends may represent the accumidated earnings of former years, while in the second, the surplus may have lieen invested in the ac(|uisition of new property, in tlie erection of new plants, etc. With these i|ualiti- ctitions, the following comparati\'e summary is pre- sented: T.ABLE S. — Siitiuiiari/ for dii'idead paying and nondivideud jtaying companies: 1902.

It appears from the preceding table that the dividend paying conijjanies enjoyed no advantage either in the grade of their ore or in the marketing of the same, since the average prices received by them did not per- ceptibly difl'er from those generally prevailing in 1902. But the two classes differed in the volume of production; the average for dividend paying companies was twice as large as that for the nondivideud paying companies, the a\erage being |83,402 and $40,976, respectively.

The number of .salaried official.s. clerk.s, etc., for the 559 mine.s reporting was 910, or an average of l.*J to a mine. Of these 76 were salaried ofiicials of corpora- tions. Since the total number of corporations was 161, it appears that more than one-half of them had no sala- ried officials. The average number of wage-earners was 7,1S81, or 14 to a mine. The aggregate wages paid amounted to $4,329,^71. Miners working in the mines on shares are not included in the general tables. In any analysis of these figures it must be borne in mind that the above number of wage-earners is an average computed on the basis of 300 working days, and is not identical with the actual number of persons who earned the amount of wages reported. The aver- age per wage-earner accordingly represents the cost of one man's labor power to the employer, and this cost is not identical with the average annual earnings. For the purpose of estimating the earning capacity of wage- earners, average daily rates should be consulted.

In the above table 6,0(»8 wage-earners, or 76.2 per cent of the total number, are included under the two heads "miners" and "all other wage- earners." It will be noticed also that there i.s comparatively little differ- ence in the range of wages for the several classes of employees. 30223—04 29 Of the total number of wage-earners, 7,196, or 91.3 per cent, ret;eived between $1.25 and $2.49 per daj'. Of those classed as miners the proportion included between those rates was even greater, constituting 95.4 per cent of all the miners. The number of miners who received f 1.50 per day was evidently very large, as was also that 450 .AIINKS AND QUARRIES. of those who were paid $3 per daj-, for 27.5 per cent are iiichided in the ^-roup $1.50 to $1.74 and 36.9 per cent in the g-roup P2 to $2.24. There were (!5S men reported as miners' helpers. The daily rates of pay lor 485 of them, 73.7 per cent of the total number, were between $1.25 and $1.74. Only 3t) men were reported as timbermen and track layers; the rates of pay for 34 of these men ranged from $1.25 to $2.24. Most of the men employed as firemen re- ceived between $1.24 and $2.24 per day; !»1.5 per cent of the total numlier was included between those rates. The rate at which the greatest number were employed was probably $1.50, since 40.4 per cent are included in the group $1.50 to $1.74. For engineers, machinists, and other mechanics wages were somewhat higher. Of the engineers, 93.7 per cent, and of the machinists and other mechanics, Si».3 per cent, were paid l^etween $1.50 and $2.74 per day. There were 30 boys under 16 years reported as em- ployed in lead and zinc mines, 28 of them from Mis- souri. Of these boys. 12 were paid between 50 and 74 cents per day, 5 were paid less than 50 cents, while 5 received between 75 and 99 cents, and 8 received $1 or over. The proportion of the employees included under the head of '"all other wage-earners" is very large, but the range of wages differed \ery little from that for the balance of the wage-earners, 94.1 per cent of the total nund)er having received between $1 and $2.49 per day. Contract mining, i. e., working at a stated rate per ton, is exceptional in lead-zinc mining; according to the reports a total of $266 was paid for such wnrk during the year, and this amount has been included in the general tables. In those mines, however, where the landowner or lirst lessee is also the buyer of all ore mined by the sublessees, the latter are virtually wage- earners paid by the ton. The total nundter of such sublessees reported was 63S and the total amount paid to them was $234,461; out of this amount they were retpiired to furnish their own su[)plies. The total numl)er of men engaged in mining can not 1)6 ascertained with aecui-acy. The lead and zinc mine inspector of Missouri reported 11,358 men employed in all capacities at the lead and zinc mines; he explained, however, that "it must not tie understood that this number is employed continuously, as (piite a number of farmers mine in many counties when not engaged in farm work."' The census returns from the lead and zinc mines of Missouri show an average of ti,612 wage- earners and 777 salaried employees, in all 7.3S9 persons. The average nund)er of the census is the number that would l:)e required at continuous employment for 300 days in the year to produce the (piantity of ore reported. The two numbers are inconunensurate; the difference l)etween them, 3,969 persons, would be much in excess of the average number of nnners working on shares, as well as of the actual numbci' of such miners ^\■ho atone time or another during the year pei'form some work in the mines.

Production. — In 1902 the dressing of the ore was done at the mine in nearly every case. Of the .5.59 concerns reporting, 525 Avere equipped with concen- trating plants or hand jigs, 1(1 were custom mills, and 18 made no report as to equipment for treating the ore, presumablj' having no facilities for dressing their ore at the mine. The total reported value of the product of the lead and zinc mines and mills in 1902 was §14.ti0o.lT7. This amount was made uj) as shown in the following statement: Vidne i,f Ihr Inul n,i,l :iiir pruihirl.- 10(U. I'rodnetion of mines: Lead ore .55,8.50,721 Zi nc ore **.

In actual practice a portion of the product of the custom mills was recov- ered from "sludge," i. e., mill refuse purchased from the neighboring mines equipped with mills. The re- ports of the latter are assumed to include the value realized from the sale of sludge; it is, however, by no means certain that these \aluesare included in all cases. The shidge is considered of little value; it is usuallj' sold for a lump sum. without much regard to ([uantitv. It is possible, therefore, that by deducting the value of purchased ore from the total value of the product the value of the lead and zinc product niav have been under- rated. Likewise, by omitting from the ([uantity of the product shown in Talile 18, the output of custom mills, the total production may have been underrated. Still, as the gross \'alue of all the ore sold l;)y the mills amounted to only $122, (i4t), or less than 1 per cent of the total production of the lead-zinc mines, the error may be treated as a negligible quantity. The quantity, total value, and average value per ton of lead and zinc ore produced in 1902 are shown by states and territories in the following table: Table 13.— QUANTITY, TOTAL VALUE, AND AVERAGE VALUE PER TON OF LEAD AND ZINC ORE, BY STATES AND TERRITORIES: 1902.

As evidenced by the preceding statement, the census returns on production are in substantial agreement with those of the state mine inspector. Small discrep- ancies of from 1 to 3 per cent are quite unavoidable in view of the nature of the information. In many cases the value reported by the operator was not the actual amount entered on his books, but an estimate based upon an assumed average value of the ore, which was the best information obtainable. Small operators only too often keep very imperfect books, if any, whereas the largest producers, who do not sell their ores but smelt them at their own plants and mar- ket the bullion, must put an assumed valuation upon the ore in order to answer the inquiries of the Bureau of the Census or of the state bureau of mines. There- fore, if the reports of such operators were made on different dates, the estimates for the same mining com- Yjany might differ, and in more than one case this state of affairs was disclosed by a comparison of the confiden- tial census returns with the figures published by the state mine inspector. That the discrepancy is on the whole within such narrow limits may he accepted as proof of the substantial accuracy of the returns. The mining district comprising Kansas and a portion of Missouri is called the Joplin-Galena district. The average base prices of zinc and lead ores in this district, computed from monthl}^ averages for 1902, were re- ported by the United States Geological Survey as fol- lows: Lead per 1,000 pounds, |123.05; zinc per short ton, $30.33. For 1902 the range of fluctuations of monthly base prices in the same district was as follows: Lead ore per 1,000 pounds. Zinc ore per short ton. Highest price ,. Lowest price S25. 00 21.00 $34. 37 26. 76 4.00 7.61 These averages arc not strictly comparable with the average values by states and territories given in Table 18.

Tiie quantity reported represents dressed ore of various grades, except in a few cases where the (luantity of rough ore was reported and could not be reduced to terms of dressed ore.

The following table, reproduced from the report of the state lead and zinc mine inspector of Missouri for 1902, shows the growth of the zinc production in that state, bj' ^^ears, from the beginning of zinc mining, in 1873, to the year 1902. The output of 1902, as reported by the state mine inspector, exceeds by eight- tenths of 1 per cent that reported to the Bureau of the Census. The reasons for this insignificant variance are discussed on a previous page. Table 18. — (Jiiaviilij (in.d value of zinr ore, Missouri : IS7.i lo l'.i()2.

The six months accounted for above are the last six months of 1900, making full years for the period. LEAD CONTKNTS OF LEAD AND ZINC ORES. The lead contents of the ore can be estimated by com- parison with the returns from lead smelters. The re- turns from 5 leading mining and smelting companies of Missouri .show a total of 103,428 tons of their own and purchased ore treated, from which 70,491 tons of lead were recovered, or an average of 68.2 per cent. The quantity of nonargentiferous lead ore treated b}' those companies is equal to 78 per cent of the total quantity mined during the year. A glance at the price column of Table 13 shows that the ore was brought b}- concen- tration to about the same grade throughout the nonar- gentiferous lead region. The only exception is found in the group of "all other states," where the quantity reported apparently' represented crude oi'e. The c^uan- tity, however, being only somewhat over two-tenths of 1 per cent, the effect of this variation upon the average for the United States could not exceed a few cents per ton. The average percentage of recovery reported by the above-mentioned .5 smelting companies — viz, 68 per cent — may therefore be taken as representative of the results generally obtained in the United States.^ The metal yield of all nonargentiferous ores may be esti- mated on this basis, in round figures, at 90,000 tons. According to reports from the same companies, lead bullion of the value of $2,534,683 was produced from concentrates valued at $2,045,978 — i. e., 24 per cent was added to the value of concentrates by smelting. The total reported value of the lead concentrates produced in the United States was $5,S50.721. By an addition of 24 per cent of this amount $7,255,00(1 is obtained as the estimated value of the 90,000 tons of metallic lead 'The relation of the product to lead ores consumed in 1880 was represented by the following percentages: Illinois, 68.6; Iowa, 70.2; Wisconsin, 66.6; Kansas, 69.3; and Missouri, 72.4. 454 MINES AND QUARRIP]S. recoverable from nonargentiferous ores. The average value is 4.03 cents per pound of refined lead, which is within the range of the prices of lead at New York city in 1902 as reported by the United States Geological Sur- vey — viz, highest, 4.10 cents; lowest, 4 cents. There- ports made by smelters to the United States Geological Survey show 79,445 tons of pig lead produced from nonargentiferous ores of Missouri, Kansas, Wisconsin, Illinois, Iowa, Virginia, and Kentucky. The difference is accounted for by the fact that "a considerable quan- tity of the ore is converted into a pigment."^ ZINC CONTENTS OF LEAD AND ZINC ORES. The zinc ores of Missouri and Kansas are usually sold upon an assay basis of (!0 per cent of metallic zinc in the concentrates, with a deduction of $1 for every unit or percentage below that standard, and a similar allow- ance for higher grades of concentrates. Sixty per cent is thought to be, approximately, the average for the entire district. The price of ore shipped from mines in Wisconsin is determined by the price of ore in Missouri. The avei'age value per ton of zinc ore in Missouri was $29. 13, and in Wisconsin $18.14; the difference, $10.99, may be taken as reflecting the difference in the grade of the concentrates, and would show an average assay of 49 per cent for Wisconsin ore (dressed). The three states named furnished 278,727 tons out of a total of 283,680 tons for the W^estern states, or 98.3 per cent of the total output of western mines. The eastern and southern ores are of a much lower grade. The average zinc con- tents of New Jersey concentrates was about 2.5 percent; the chemical composition of the ore, according to Mr. Ingalls, is 23.58 per cent zinc. The concentrates of Virginia assay 38.08 zinc.'' From these data the zinc contents of the ores mined are estimated for the prin- cipal producing states as follows: Table 19. — Zitic contents of ores mined In the principid producing states: 190i!.

' The computation is made separately for New Jersey and Virginia, but the returns can not be shown separately without disclo.sing individual operations. This leaves 8,725 tons of ore, or about 2 per cent, the zinc contents of which are a matter of conjecture. GENERAL SUMMARY OF LEAD AND ZINC MINES, BY STATES AND CHARACTER OF MINE. A table for all lead and zinc mines is presented by states. Small mines from which no individual reports were received are not included in this statement. The royalties shown in the detailed summar}' at the close of this report include those paid by these sublessees; there- fore royalties are omitted also. The rate of royalty is fixed by custom and does not, as a rule, vary in indi- vidual cases. Custom mills which merely rework ore mined elsewhere or mill refuse ("sludge") are not in- cluded in the following table which is intended to pre- sent the facts relating to mines only: ' Proiluction and Properties of Zinc, by Walter Benton Ingalls, jiages 198 and 2(11.

The average value realized per ton of lead ore shows no marked ditierence for either class of lead mines. The average values per ton of zinc ore, shown in the preceding table, are misleading because they include the low grade zinc ores of New Jersey and Virginia. When those ores are eliminated, the total output of dis- tinctively zinc mines is reduced to 62,453 tons, valued at f 1,824,470, which corresponds to an average value of $29 per ton. Thus there is no perceptible difference in the average value of zinc ore of the .same class. The following is a comparative summary of zinc mines by districts, viz, Kan.sas and Missouri, which i.s the main zinc producing region; the upper Mississippi valley, extending over Wisconsin, Illinois, and Iowa; and the Eastern states, embracing New Jersey and Virginia: Table 33.— SUMMARY' FOR MINES PRODUCING ZINC ORE EXCLUSIVELY', BY' DISTRICTS: 1902.

The statistics of mines producing auriferous and argentiferous lead and zinc ores are given in the report on gold and silver. Still, as these ores furnish a not inconsiderable share of the materials from which lead and zinc are produced in this country, a proper com- parison of the production of the mines with the con- sumption of the lead and zinc ores must embrace all classes of these ores. The production of lead and zinc from all sources, as returned by the census of mines and (Quarries for the year 1902, is collated in the follow- ing statement: ]'roil(ii1ioii: 1903. Lead. Zinc.

Mr. Hari\y A. Lee, commis.sionci- of inine.s of Colo- rado, in his report for 1901-2, wrote as follows of zinc mining in that state: Zinc is practically a new product that i jccurs intimately associated with iron and lead sulphides in bodies of great magnitude. TTntil within the past few years these ore bodies were wurtbless on ac- count of the zinc sulphides present, anil were, therefore, as far as possible, left intact in the mines. The extraction of the more valu- able ores has, nevertheless, developed large bodies of zinciferous ores that are now a valuable asset.' Zinc associated with gold, silver, and lead was re- ported from Colorado, where, according to census returns, 51,996,073 pounds of zinc were contained in 2-i5,555 tons of gold and silver })earing lead ore, show- ing an average assay of 10.6 per cent of zinc in the ore. In addition to this, the reports from nonargentiferous ^ Report of the State Bureau of :Mines of Colorado for the years 1901-2, page 105. lead and zinc mines included in the preceding statements show a product of 1,.536 tons of zinc concentrates. The commissioner of mines estimated the production for 1902 at 52,.582,510 pounds of zinc. Thi.s leaves 586,437 pounds for the contents of 1,536 tons of nonargentifer- ous lead and zinc ore included in previous statements, which would correspond to 19.5 per cent of zinc in the dressed ore. The estimate is apparently too low. The value reported to the Bureau of the Census is $335,436 for the zinc contents of argentiferous ore and 118,398 for the lead and zinc ores; in all, |3.53,S34. The value reported by the commissioner of mines was com- puted at the average price for .spelter, 4.84 cents per pound, which amounts to $2,544,993. The price realized by the mine operator was about 13.9 per cent of the value of metallic zinc contained in the ore.

Lead smelters very reluctantly handle this class of ore; they make no allowance for the zinc, and even charge a penalty in case the assaj' shows zinc in excess of a certain percentage. According to Census reports, concentration and magnetic separation of zinc ore have been introduced at some iniiics. Ship- ments of zinc ore were made to Kansas zinc smelters and to New York for export. IJndcu- th(^ stinmlus of the growing supply of zinc ore, zinc works have been recently erected in C(.>lorado. Reports from Utah show 19,5,S2,443 pounds of zinc among the contents of argentiferous lead ore. With the exception of a small shipment iissaying 105, 000 pounds of zinc, no returns were brought by the zinc, although the rough ore assayed 4.2 per cent zinc The ore was bought by lead smelters for its gold, silver, and lead contents. In Utah as well as in Colorado there were other mines which produced zinciferou.s ores; but since the operators received no returns for their zinc, they kept no records of the same, and failed to report it to the Bureau of the Census. Consumption of zinc ore. — The zinc contents of lead and zinc ore were estimated above at 217,726 tons, ex- clusive of the contents of S,725 tons, which could not be estimated with any degree of accuracy. The zinc contents of auiiferous and argentiferous ores were given in Census rejjorts from Colorado as 25,998 tons. The reports from Utah showed one shipment of ore as.saying 52 tons of zinc, for which payment was re- ceived. This makes a total of 243,776 tons of zinc and 8,725 tons of zin<' ore. No account is taken of zincifer- ous ore shipped to lead smelters, there being no posi- tive information to show how the zinc contents of such ores were utilized, or even that they were utilized at all. The production of spelter for 1902 was reported by the United States ({eological Survey as 156,927 tons. Allowing 15 per cent for the lo.ss in smelting, the zinc contents of the ores from which this output was ex- tracted, may be estimated at 184,600 tons. To this must be added the output of zinc oxide, which is manu- factured in the United States directly from the ore. The production of zinc oxide for l',M)2 is estimated' at 52,730 tons. The zinc contents of this product, figured at the rate of 80.3 per cent of zinc in the oxide, were e(|ual to 42,342 tons. The total output of zinc in all 'The Mineral Industry, \'iil.

The expoi'ts of zinc ore for the calendar year 1902 were 49,762 long tons,' or 55,733 short tons. Of this quantity, 20,S«3 long tons were exported through New York; the rest, with the exception of a small quantity, was exported through Galveston. The New York ex- ports represented New Jersey ores which contained, at an assay rate of about 25 per cent, 5,221 long tons or 5,847 short tons of zinc. The estimated production and consumption would thus compare as follows: Production and consumption of zinc: 1903. Zinc (short tons). Ore (short tons).

The deficiencjr of 23,619 tons of ore in the preceding calculation is covered by the excess of 10,929 tons of zinc, which corresponds to an average tenor of 46 per cent zinc in western ores. No account is taken here of the increase or decrease of the stock of ore. It must be understood that these are onlj^ rough estimates, allowing a wide range for error. Tendency toward centralization. — The lead-zinc min- ing industry has not escaped the general trend of modern business toward centralization. In this respect a marked difference in degree exists between those mines which may be classed as zinc mines, lead being mined onlj- as a by-product, and those which may properlj^ be classed as lead mines, zinc occurring, if at all, as a by-product. The following table shows the distribution of lead mines by value of production in 1902: ' Mineral Resources of the Table 24. — Classification of lead mines by value of product: 1903.^ ' United States Geological Survey, United States," 1902, page 225.

Missouri. — The state lead and zinc mine inspector of Missouri, in his report for 1902, noted the decrease within recent 3fears of the number of individual oper- ators, who were giving place to large and strong com- panies.'' As the mines of Missouri furnish the bulk of the zinc and soft lead production of the United States, the tendencies observed in Missouri ma}^ be .said to be representative of the industry in general. In .soft lead mining the progress of centralization is far in advance of that manifested by the zinc mining industry. The degree of centralization reached in each branch appears from Tables 26 and 27, which show the distribution of all operators by value of production. This classification does not include the great number of sublessees employing no hired labor. '•'Sixteenth Annual Report of the State Lead and Zinc iline Inspector of Missouri, pages 10 and 11.

Three opera- tors, each with an output exceeding $500,000, produced over one-half of the lead output of the state. Tables 28 and 29, showing the correlation between the value of production and ownership of mineral lands, have been compiled in this office from the individual reports of mining companies published in the annual report of the lead and zinc mine inspector of the state of Missouri for the vear 1902.

As appears from the preceding table, the title to all lead bearing lands in Missouri were concentrated in the hands of 45 owners, 94 per cent of all the lands being held by 12 owners in tracts of over 1,(.)00 acres. The same properties furnished over three-fourths (77.74 per cent) of the total production. The production per acre decreased with the increase of the acreage, the range being from $628 per acre for the small properties to $41 per acre for the larger ones; this points to the fact that the larger properties are as yet undeveloped.

The average computed for all mines of the same states was about %4:-i. The value per ton of zinc ore realized by the operators using only hand and animal power aver- aged about $18, and the average computed for all mines of the same states was lil^ewise al)out $18. This shows that in marketing their ores the small operators enjoved the same facilities as all other competitors in the lead and zinc market. The detailed statistics of lead and zinc mining for 1902 are given in Table 34. DESCKIPTIVE. The earliest discovery of lead on the American conti- nent is recorded fourteen years after the landing of the first English settlers in Virginia. In 1621 lead deposits were found in the vicinity of Falling creek, near Jamt'stown. The steady tide of Europetui immi- gration in the seventeenth and eighteenth centuries caused a growing demand for bullets and stimulated further discoveries wherever the settlements of the colonists extended. The Frem-li actjuainted the north- western Indians with firearms, inducing them to hunt 400 ]\IINES AND QUARRIES. fur l)earino- animals on a large scale; consequently lead assunieel a value in the eyes of the Indians, both for use in making bullets for their own weapons and as an article of traffic. Toward the close of the seventeenth centurv the Indians living in the region comprising portions of the present states of Wisconsin, Illinois, and Iowa, were smelting lead and bartering it with the French traders. In the second half of the eighteenth century lead had become of such importance in the trade of the upper Mississippi country that it served as currency, the rate of exchange being a peck of corn for a peck of ore. In 1810 Nicholas Boilvin, United States Indian agent at Prairie du Chien, went on foot from Rock Island to the mouth of the Wisconsin, and reported that the Indians of the region had "mostly abandoned the chase, except to furnish themselves with meat, and turned their attention to the manufacture of lead."^ Previous to the Louisiana purchase nearly all the valuable lead mining lands were within the domains of France and Spain. Soon after these lands had passed under the jurisdiction of the United States, Congress, by the act of March 3, 1807, reserved all Government lands bearing lead ores, and authorized leases of these lands. The first leases provided for a 10 per cent roy- alty on the lead produced; the rate was afterwards re- duced to 6 per cent. No leases were issued until 1822, when crowds of prospectors began to enter this region. A few years later the mines gave emplo3'ment to over 2,000 men, many of them farmers, who with their slaves spent onlv their spare time in the mines. The royalties were paid with some regularity for a short time only; after 1834, as a consequence of the immense number of illegal entries of mineral land at the Wiscon- sin land office, the smelters and miners refused to make any further payments, and the Government was unable to collect any royalty from them. After much trouble and expense, it was, in 1847, finally concluded to sell the mineral lands.* The chief lefid mining districts, which to-day furnish the bulk of the lead production of the United States, were not developed until nmch later. Tlie lead deposits of the Joplin-Galena district, embracing southwestern Missouri and pait of Kansas, were discovered in 1848, but attracted little attention before the Civil ^\'ar. The great western deposits of argentiferous galena were discovered in 18f>2. The.se words of one who was an expert in his own time have a peculiar sound to-day, when it is consid- ered that over $8,000,000 was won from the western zinc deposits in 1902. For over half a century zinc ore was taken out of the mines of the southwestern part of Missouri, in connec- tion with lead ore, and thrown upon the dump pile as worthless. Mines were deserted because of the prevalence of this refuse or "tifi'," as it was called by the miners. In the early seventies this joeculiar look- ing substance, which was causing the lead miners so much trouble, was examined by a geologist and pro- nounced to he zinc ore. A carload of it was shipped to Lasalle, 111., for treatment. The smelter returned |15 for the carload, telling the shippers that it was a high grade of zinc ore. This led to further shipments of the ore. Abandoned mines were graduall}' reopened be- cause of the zinc ore the}^ contained, and in 1902 the zinc product of Missouri was more than eleven times the value of all the zinc ore mined in the Eastern states, where zinc mining dates back to 1848, and where the mines were the main source of the domestic zinc supply previous to the development of the Joplin-Galena district. Biixhu'HH iirf/aiiization. — The last twenty years in the history of the lead-zinc mining industry have been a period of change. A contemporaneous description of the Vjusiness methods of twenty vcars ago is given in the following excerpts: When a good prospect is discovered in new ground the land around it is leased from the original owners on ro}'altie8 ranging from 10 to 25 per cent by a number of individuals, wdio organize various mining, fir, as they would more properly be called, land companies.

Bv JsAAC A. HolMlWKni, I'll. 1). The statistics for I'oppei' ore in this report are those of mines producing ores, the prini'ipal or only value of which is their copper contents. The statistics for ore dressing- works (stamp mills and concentrating plants) connected with copper mines ai-e included in the returns. Copper is recovered also as a by-product of the smelt- ing of ores valued chiefly for their precious metal con- tents. All statistics relating to the mining of tliese ores are included in the returns for gold and silver mines. Smelters are regarded as manufacturing establishments and were included in the Report on Manufactures of the Census of 1!>U(.). The following tal;)le is a comparative summary of the statistics of copper mines from 1S<')(.) to 1902: Table 1.— (.'(JMPARATIVE SU.AIMAKY; ISHO To 15102. Number of mines Number of operators . . .

I Value of .5,4I0..'JJ(i pounds .i( coiijirr fur Western slati During the forty-two years covei'cd by th(> table the growth of copper mining has lieen very marked, the value of products having increased $47, SI*), Sl-f, or over fourteenfold. The increase in the total wages was $19,335, 2i5, or nearly elevenfold. It was found that in most of the acti\e mines no sep- arate account was kept for devclopuKMit work. The expenses of pi-oducing mines, therefore, include the cost of development work incidental to mining. Con- siderable development work was done m mines that reported no production. Most of them were located in the Western states, where the mineralogical character of the ore was described as auriferous and ai'gentifer- ous copper, yet it woukl not be practical)le to classify such mines as copper, or gold and silver mines, in accordance with the chief valuable (ihnuent of the ore, before they have become regular producers.

JTumher of inhh's and (iperaforx. — The terms "'mine" and '"operator," a.s used in this report, require a word of explanation. In some eases certain properties wex'e combined by the owner under one management and reported as one mine, while others were operated as separate mines and so reported. When a "group" of mines was included in one report, it was v^vj largely a matter of opinion whether all or some of the properties constituting the group were to be considered as separate mines, or whether all properties had been merged into one mine. The onh' relialile unit of enumeration was the reporting corporation, iirm. or individual. Among these were 2 corporations whose luines were operated by lessees and 1 holding company, the Amalgamated Copper Company. The capitalization of the tirst two was a distinct element of the capital invested in copper mining, cpiite independent of the capital invested by the lessee, and it was believed, therefore, that this ought to be included in the total capitalization reported for the copper mining industry. As regards the Amal- gamated Copper Company, it is a matter of opinion whether it or the companies whose entire stock is owned by it should be regarded as the actual operators. It was therefore thought preferable to show in the tables the tc_)tal number of companies reporting. If the holding company and the two lessors are excluded from the total number reporting, then the number of operators was 141. If, on the other hand, the con- stituent companies of the Anialgamateil Copper Com- pany are excluded, then the total number of operators was 136. Clioracter of (iii'iiei'xhi l>. — The corporate form of own- ership was the predominating type in the copper mining industry. Of the 141 operators 1(H) were incorporated companies, 23 were firms or limited partnerships, T.i were individuals. 1 was a (■oo]ierati\'e association, and I was an estate. In Michigan all c(i])])cr mining (i]ier- ators were incorporated. A summary of all copper mines. classiHed by character of ownership, is presented in Table 2. Table ^. — Sinjiiiinrii, hy rjicirncli'r of oinier^Iiiji: 190S. ' Inclurles 2 mines cljisse^l under "other forms.'" It appears from the preceding table that the share contributed l)y each class of operators to the output of the mines was as follows: Incf)r])orated companies. $50.421, .S3T. or H8..5 per cent; individuals, $594,377, or 1.2 per cent; tirms, 1^161,822, or three-tenths of 1 per cent. Al)out three-fourths of the copper ore mined b^' individuals and firms was sold in the crude state, the remaining one-fourth being dressed or smelted at the mine. The incorporated companies, on the contrary, sold only (i per cent of their ore in the crude state, namely, a product valued at $4,5115.588; the value of dressed ore sold by them was Ss. 611, 415, or 11.3 per cent, and that of ore smelted at the mine or shipped to smelters opei-ated by the same companies was §63.109,113, or 82.7 per cent. i'lip'ifiil stocJi' of iiicorj>ori(t(\l conijiiiiiii n. — The capi- talization of the incor]")(irat(>rl companies is shown in Table 3. In the consideration of the capitalization of the copper miiung companies, it should be borne in mind that a jiortion of the capital stoclc of some of them represented the valn(^ of smelting plants owned and operated by the same companies.

(ino Dividends. — The total amount of dividends paid in 1902 was $14,116,002. Of this amount, $3,077,760 was paid by the Amalgamated Copper Company. These dividends were derived partly from the dividends declared by its constituent companies, and partly fr(.)m the earnings of other properties of the Amalgamated Copper Company, such as coal mines, railways, etc. The following table shows the capitalization and di\'i- deuds of all dividend paying companies, with the excep- tion of the Amalgamated Copper Company, and also the capitalization of the companies tliat paid no divi- dends in IHOL': Table 6.— INCORPORATKH C0:\IPANIES, ( 'LA.ssIFIEIi WITH ULL.VTKiX TO I H VIDENDS, CAPITAL STOCK, AND BONDS: 1!H)L'.

COPPER. 478 There were 18 dividend paying- companies, with capi- tal stocli issued tt) the value of $113,-±62,i)27; whereas 81 companies, with capital stock issued to the value of $104,889,343, declared no dividends. Dividends on $10,6.51,500 of preferred stock were declared by 4 com- panies,; the rate of dividends averag-ed 4.3 per t'cnt. No dividends were declared by these companies on thcii- common stock, which was issued to the amount of 145,965,097. Two companies with preferred stock authorized declared no dividends; the authorized pre- ferred stock of these companies was $l,5tH),000; the amount issued, f 300,000. Dividends on common stock were declared by 14 com- panies with an authorized capitalization of $75,150,000, of which $56,946,330 was outstandino-; no preferred stock was authorized by these companies. The average rate of dividends on connnon stock was 18.6 per cent. A comparison between the par values of dividend paying and nondividend paying stocks is not without interest. The average par value per share of dividend paving common stock was $21.07, whereas the average par value of a share of common stock on which no dividends were declared was only $4. 11. Similarly, the par value per share of preferred stock was $10.71 for dividend paying- and only $1 for nondividend paying- companies. It is apparent that the type of mining- enterprises, for which capital stock is issued at $1 and less per share, is more frequent among nondividend paying- than among- dividend paying- companies. The latter are, for the most part, concerns the capital stock of which is issued at prevailing commercial values per share, viz, at $25 and over.

The rate of inter- est on bonds averaged 5.8 percent. A number of corporations operated both copper mines and smelters, and some were interested in other prop- erties, such as coal or iron mines, railways, etc. The dividends reported for such companies were derived from all those sources and can not lie segregated. A comparative summary of dividend paying com- panies — with the exception of the Amalgamated Copper Company, which, being merely a holding company, is therefore excluded — and those which declared no divi- dends in 1902, is presented in Table 7.

It must be borne in mind that the payment of divi- dends in a given vear is not indicative of profits earned during that year. Dividends may be declared from the accumulated surplus of former years. On the other hand, the failure to declare a dividend does not neces- sarily show a loss; the earnings may have been invested in development work, in new equipment for the plants, in acquiring new property, etc. Some of the principal copper mining companies are close corporations, the stock of which is held bj^ a limited numlier of persons. As the shares are not on the market, it is often a matter of indifference to the stockholders whether a dividend is declared or the net earnings are accumulated as a surplus. The chief ditlerences disclosed by the preceding- table between the dividend paying corporations and those which paid no dividends in 1902 ai'e as follows: First. The grade of ore mined was higher with the former than with the latter, viz, $8.20 pei- ton as against $5.25 per ton. Second. Where dividends were paid the ore was nearly all smelted at works connected with the mines, whereas in other cases much of the ore was sold. Third. The ax'erage value of product per dividend paying company was $1,826,589. while the averag<' for other companies was only $216,583; apparently it was the largest companies that declared dividends in l'.io2. The census returns for 1902 cover a year of low prices of copjxM-. .V comparison with the dividends for previous vears will be found on a subsei[uent page, in connection with a study of prices.

Practically all those classed as miners were paid at least |'.2 per day, and ,5,552 of them, or 43.3 per cent, received between $3.50 and $3.74. Most of the highly paid miners were reported from Montana and Arizona. Of those classed as miners' helpers, 1,257 in all, tu;.3 per cent were paid between $1.75 and $2.24, 22.1 per cent having received le.ss than $1.75, and 11. (> per cent, $2.25 or over. There was a wide range in the rates paid to timtiei-men and track layers; 454, or 52.6 per cent of the total number, were paid between $1.75 and $2.24, and 24 per cent, from $3.50 to $3.74. Prac- tically all of the timbermen and track layers at $3.50 or over were reported from Montana. There was also a wide range in th(>. rates for engineers, firemen, machinists, and other mechanics. In each of these three classes more than !♦(• per cent of the wage-earners received $1.75 per day or over. The proportion receiving $3.50 or over was as follows: Engineers, 43.6 per cent; firemen, 28.3 per cent; and machinists and other mechanics, 42.6 per cent. In each case the greatest number at rates of $3.50 or over were reported from Montana and Arizona. COPPER. 475 The number of boys under Ifi years employed was .small, only 103, or less than live-tenths of 1 per cent, having- been reported. Their rates varied from 50 cents to $2.49 a day. Of the 103 boys, 50 were employed in Arizona and 37 in Michigan. The 8,105 employees grouped under "all other wage- earners" constituted 31.2 per cent of the total number. Their duties were so varied as to render impossible any separation into well-defined occupations. The rates of pay for the greater portion of these wage-earners ranged from $1..50 to $2.24 per day, 74.3 percent being in- cluded l)etween those rates.

Only Arizona, Michigan, and Montana are shown separately. These 3 states gave employment to 24,072 wage-earners, or 92.6 per cent of the total number em- ployed in mines, the principal product of which was copper ore. Of the 3 states, Montana shows liy far the highest rates, 6,095 wage-earners, or 95.4 per cent of the total number, receiving $3.50 per daj^ or over. In Arizona 37.5 per cent of the wage-earners received $3.50 or over per day, and 40.1 per cent from $1.75 to $2.49. In Michigan the wages paid were much lower than in either Arizona or Montana, practically all of the men employed in copper mines in that state receiv- ing between $1.50 and $2.74. The 1,935 wage-earners grouped under •'all other states" are distributed among 13 states, no single state reporting as many as 500. The tenacity of antiquated forms of industrial rela- tions is exemplified in the few copper mines Avhere labor was performed on a share of the product. This form of employment is frequently found in gold mines, where the miners so employed are locally known as "leasers," "'tributers," etc. There were only 7 cases of this kind reported at copper mines, namely, 4 in Montana, of which 3 were in Silverbow county; 2 in Arizona; and 1 in Colorado. In all, 22 men besides the regular wage-earners found employment on such terms in these mines. The total output was valued at $25,567 at the mines, the output of no mine exceeding $10,000 in value. The percentage of copper in the ore varied from 6 to 29 per cent. The share received by the mine owner ranged from 10 to 20 per cent of the gross value of the ore, and from 10 to 25 per cent of the value at the mine, after smelting and freight charges were deducted. The miner, out of his share of the product, furnished his own supplies.

The total amount reported under this head was $1,397,46.5.

On the Mdiole, ro\'alties and rents were but an insignificant item in the copper mining industry. All other miscellaneous expenses aggregated $1,267,250. Supplies and materiah. — The general term ''mate- rials " has scarcely any application to copper mining. The ''material" operated upon in a mine is the rock underground. The inquiry calling for " total cost of sup- plies and materials of all kinds used during the year" at the mine contained the following explanatory note: "The cost of the following materials should be re- ported under this inquiry: Lumber and timber used for repairs, mine supports, track ties, cars, and all other purjjoses; iron and steel for blacksmithing, rails, frogs, sleepers, etc., for tracks and repairs, parts of machineiT and tools used for renewals and repairs; explosives, water for boilers and for other purposes, fuel, illumi- nating and lubricating oils, machinery supplies, etc." All the items here enumerated strictly come under the definition of "supplies." The "material" treated at the mills is the ore which comes from the mine. It is not customary in mining bookkeeping to charge the mill with the value of the ore brought from the mine. In the schedule relating to "reduction works, other than smelters," there were two separate inquiries, one relating to "materials," the other to '"supplies." The former called for a statement of the '" character of ma- terials used, whether ore. tailings, or other materials," and was confined to ''materials bought in 1902." The amoinit reported in answer to this iiK|iiiry is not in- cluded in the "cost of supplies and materials" shown in Table 1. but is gi\-i'n as a separate iti-ni. I'nrchased ores formed buf a very insigniticaiit pai't of the total tonnage treated at mills eoiuiected with copjier mines, namely, l,(t68 tons out of a total of 6..j.'')S,222 tons treated in 1902. The explanatory note to thi' in(|iiii-y relating (o mill "supplies" enumerated: "Shoes, dies, screens, jilates, and other parts of machinery and tools used for renewals and repairs; ijuicksihcr, cyanide of potassium, lumber, iron, steel, oil, fuel, water, etc." The total cost of "supplies and materials," as herein d from 13 mines, of which 1 used also steampower and 1 water- powin-.

Therefore the value of this ore, $19,733, is deducted from the total value reported for COPPER. 479 1902. Yet it i.s po.s.sihle that this ore may have come, in part at lea.st, from mines idle in 1902. The error, if any, is a negligible quantity.

Some silver was contained in the copper ores mined in every state; but the silver contents of the Lake' Superior ores were too insignificant to pay for the cost of recovering them, and, as a rule, brought no value to the owner. For the .same reason no returns were made to the mine operator for the gold and silver contents of the southern ore, though some of them ultima telj' reached the eastern electrolytic refineries where the precious metals were saved, thus increasing the refined gold and silver product brought into the market. The average price realized by the mine operator for the copper contents of his ore varied by states, as shown in the statement below from 5.5 cents per pound m New Mexico to 11.7 cents in Michigan. The extremely low price in New Mexico was a flat price, no charges being made for smelting and freight. The variations in other states were produced bj^ the fluctuations of the New York price of copper in the course of the year, and depended further upon the manner in which the ore was disposed of, as will be fully explained.

Of the 711,140 tons dressed before smelting only 3y,551 tons, or 5.11 per eent, were shipped to outside smelters, the rest, after coneentration, was shipped for smelting- to works operated b}' the mine owners. The practice of dressing lief ore smelting was confined to Arizona. As appears from the preceding statement, the grade of ore did not vary materially with the disposition of tlie same. The way in which the ore was handled was apparently determined by the ecpiipment of the mining company. In the copper industry the combination of mining and smelting under the same operator is the predomi- nating type of organization. The total value of the ore shipped to smelting works operated in connection with mines amounted to $40,432,863, whereas the value of the ore shi]iped to custom smodters was only $10,745,173. The number of mines connected with smelters was 29, and the number from which oiv. was shipped to custom suKdters was 1L5.

The cost of reduction and freight includes all charg(>s of any description deducted l)y the bu^'cr of the on» from the gross value of the same, whenever the ore was sold, or all charges made by the smelting works against the mine wdienever both were operated by llic same owiiei'. Most of the Micliigan mines reporteil sepa- rately commissions, sellinge.xpenscs, etc. ; some reported separately the cost of haulage from mine to smelter. WHien 11 mine was operat(»d in connection with a smelter, a se})arate report was seciii-ed for the latter, e.\- cc'jit in one case, wdiere the smidter was operated merel\ as a test for a, few days. The inijiiiries called Foi- 1 lie lot ul on hand at close of year, having been neither sold nor smelted, and tlie value yoming, amount paid in salaries and wages during the year 1902, the cost of supplies used during the year, and miscel- laneous expenses, covering substantially the same items as indicated a))ove; also total tolls received for custom smidting and relining. as w(dl as total tolls paid on the product not included among mining expenses. F>ut when no charges were made on the books of the sniidter against the mine, both being operat"d ;is one establishment, the total exiicnscs COPPER. 481 reported for the smelter were reg'arded as tlie cost of smeltino- the ores shipped from the compan\''s mine and were deducted from the gross value of the bullion con- tents, in order to arrive at the value at the mine. Thus the gross value in Table V^ represents the A-alue of the refined product, and the value at mine is tiiat of the ore computed as herein explained. No attempt was made to estimate the profits of the operator on the smelting of the ores mined by him, as it would be purely a matter of conjecture. It was assumed that the ore was treated at cost, and the profit, if any, is therefore included in the value of the product at the mine. When, in addition to the ores mined, custom ores were treated by the smelter, the expenses of the smelter were apportioned between the ores mined and those purchased on the basis of the tonnage, and the amount chargeable against the mine was deducted from the gross value. The total quantity of custom ores thus treated was only 447,944 tons, as compared with 7.513,269 tons shipped from mines operated under the same management, or 5.6 per cent of the total quan- tity treated. Thus any error in that calculation could not materiall}' aflect the results. The value of the product at the mine, thus computed, represents the value of the ore, crude or dressed. -The value of the ore at the mine shown in Table 13 differs slightly from that shown in Table 15. The difference amounts to $58,059, which is due to the omission from Table 15 of the estimated value of the increase of stock of ore, amounting to $77,792, and the inclusion of the cost of purchased ores, amounting to $19,733. The average tenor of copper in the crude ore was 2.7 per cent or "units" of 20 pounds to the ton, and the average value per pound of copper contents was 11.2 cents; the gross value per ton on that basis averaged $6.79. Of the ores sold, nearly seven-eighths were Lake and Southern low-grade ores; taking the United .States as a whole, therefore, the average percentage of copper for ore sold appears to have been less than one-half of the average for ores smelted. A comparison by states discloses a diiierent condition; with the exception of Montana, ores shipped to custom smelters were of a higher grade than those smelted at the mine; appar- ently, low-grade ore could not bear the expense of ship- ment to a distant smelter, and could be profitably treated only at the mine. In Montana the grade of ore does not differ in the two cases, which is due to the fact that most of the mines are centered near Butte, so that the cost of transportation is not of such importance as elsewhere. The last group, combining the Lake Superior district and the Southern states, merely reflects the defects of the United States average, the reasons for which have been explained. The average value realized per pound of copper is 1 cent less for ore sold than for ore smelted by the owner. The same relation is observed everywhere, the differ- ence in price on Western ores varying from seven-tenths 8(t22,3— 04 ;^1 of a cent in California to 3.1 cents in LTtah. The mar- gin represents a part of the charges for the treatment of the oi'e. The low price reported from "other West- ern states'" is due to the fact, as explained abo\e, that in New Mexico ores containing 7,297,383 pounds of cop- per, and valued at $400,318 were sold at a Hat price, no deductions being made for treatment. In the Lake Su- perior district the same \'alue is allowed per pound of tine copper in the dressed ore (locally known as •'min- eral "') and in refined bullion. The slight variation of one-tenth of a cent is due to the difference in Southern oi'es. The average charges for treatment and freight nmst be compared by states or groups of states, inasmuch as the result for the United States is affected by the inclu- sion of Lake ores which are shipped to the SQielter after being considerably reduced in weight by dressing. Of the total quantity of Lake ores, 5,036,547 tons were re- duced to 120,042 tons of mineral — that is, to 2.4 per cent of the original weight. This method naturally reduced the cost per ton of rock treated. Compared hj states the cost of treatment varies; in California and Montana, as well as in the Lake Superior district and in the Southein states, there is no apparent differ- ence between the charges on ores sold and those smelted by the mine operator, whereas in all other Western states the cost of treatment is higher for the former than for the latter. A segregation of the cost of reduction into charges for treatment and freight was not in all cases obtain- able. The aggregate charges for reduction amounted to $26,762,189. This amount was distributed as Cost uf reduction of ores: 190£. Total .

Freight, as far as reported, amounted to about one-sixth of the cost of reduction for ores and concentrates shipped to outside smelters, and to about one-eighth for ores smelted at works con- nected with the mine. The item of freight amounted, in all, to $3,402,359, which was equal to a charge of 4.4 per cent on the gross value of the ore. Mines and iiiiJJy. — When a mine and reduction works were operated under the same management, separate reports were required for each, and special schedules were provided for the purpose. Still the mine operator 482 MINES AND QUARRIES. was given the option of making one report covering both the mine and the reduetion works, wlrenever it was impracticable to report them separately. In the Lake Superior district, where ore dressing is an integral part of copper mining, the reports furnished by the mine operators included in each case both the mine and the mill. Separate reports for mine and mill were received from each of the 7 western operators. A summary of these reports is presented in the following- table: Table 16. — iSummarii of mines combined irilh mills irherr sepuriitely reported: l'JO'2. Mines and mills.

The gross value of the product is obtained by deducting the cost, $19,733, of ore pur- chased for the mill, from the gross value of the bullion contents; the same amount being deducted from the reported valae of copper, in order to obtain the value of the copper contents of the ore mined. The value of the copper contents of purchased ore, of course, ex- ceeded the price paid by the mill for the crude ore. Yet as the copper contents of purchased ores were less than 1 per cent of the total cpiantity treated, they may be regarded as a negligible quantity.

' The noteworthy feature disclosed by the preceding table is the gradual concentration of production from one census to another'. Assuming that the establish- ments reporting in 1860 and 1870 represented mines, the number of mines decreased fi-om 1860 to 1880, and since then has remained about the same; but the output at each census has been about double the value or the quantity reported at the preceding census. The average production per mine was as follows: In 1860, $72,379; in 1870, $159,710; in 1S80, $419,960; and in 1902, $1,028,168. The progress in the equipment of mines went on in proportion to the increase in the volume of production. This is illustrated by the growth of the number and horsepower of .steam engines used, as summarized in the following statement: Sleiini eiiijini's iimi jiorsepoH'i'r in Michit/tin : 190:^, ISSO, n nil 1870. 1902 1880 1.870 NUMBER 01' EN- GINES.

The preceding .statement clearly shows the remarkable growth of the application of steampower, especially within the last two decades. The average power em- ployed in the production of 1 short ton of fine copi^er in 1880 was e(|ual to fif t3'-five hundredths of 1 horsepower, and in 19(»2 to 1.61 horsepower, nearly threefold. Of the 20 mines reporting in 1902, 18 made complete reports, stating the cjuantity of rock treated, the quan- tity of mineral produced, and the fine copper contents of the mineral; 3 failed to state the quantity of rock treated, but reported the quantity of mineral and cop- per contents; l reported the quantitj^ of rock treated and the fine copper contents, but failed to report the quantity of mineral produced. The total reported quan- tity of rock hoisted was 6,217,317 tons, of which 5,971,61.5 tons were treated and 275,702 tons, or 4.1 per cent, were rejected as too poor to go to the stamp mill. Complete reports from 13 mines showed 5,036,547 tons treated at stamp mills, with a yield of 240,084,170 pounds of mineral, containing 144,217,300 pounds of fine copper. The rock was reduced by treatment to 2.4 per cent of its weight; the fine copper contents averaged 6(1.1 per cent of the mineral, or 1.4 per cent of the weight of the rock. Returns from 16 mines showed 5,971.615 tons of rock treated, containing 165,631,605 pounds of fine copper, or 1.4 per cent of the quantity of ore treated. Returns from 17 mines showed 249,569,244 pounds of mineral, yielding 149,262,636 pounds of fine copper, or 59.8 per cent. The percentage of mineral produced varied in indi- vidual cases from six-tenths of 1 per cent to 2.4 per cent of the rock treated, and the copper contents varied from 53.4 per cent to 91 per cent of the mineral. The proportion of 2.4 per cent of mineral to the c[uantity of rock treated and 60 per cent for the fine copper con- tents of the mineral, or 1.4 per cent for the fine copper contents of the rock, may be taken as representing the general average. Upon this basis^the cjuantity of rock treated in case.s where mineral alone was reported may be estimated at 198,000 tons, which would raise the quantity reported to about 6,179.000 tons, or 3.2 per cent. The total quantity of rock hoisted in 1889 was 2,363.733 tons, of which 2,137,653 tons were treated, a part of the ore being rejected as too poor to go to the stump 484 MINE8 ANJ.) gUARRIES. mill.

In the statement which follows all Lake Superior copper companie,s are divided into three classes: (1) Those whose total dividends since organization have more than equalled the amount of capital stock issued, (2) those whose dividends have not equalled the amount of cajDital stock issued, and (.3) those which have never paid any dividends. ' ' active dividend paying C(jm- panies, of which, howe\-er, only '4 paid di\-idends in 1903. The total numher of acti\'e companies reported to the census of 1903 was 2(i; it is therefore apparent that 10 of this number had nexer paid any dividends. Of the 44 companies which at one time oi' another have o[)e,rated in the Lake Superior region 34 were ina<'tive or did not exist during the census year. The 2 mines mentioned aliose which closed after proving profitable investments were Clitf. which from Ls41t to l.s(i7 netted in dividends $3,4(.)T,t)30, after earning an amount equal to its capital stock of $111,000, and Central, which from 1864 to IKKI netted in dividends iiil,870,u0u, after earn- ing an amount equal to its caj^ital stock of !|l(.)0.(tn(i. A very instructive record of mining for a long series of years is presented in the published reports of the Quincy Mining Company.

With that purpose in view tlic special schedule relating to copper mines contained an in([uiry calling for the name and address of the mill or works at wdiich the ore was treated. The special schedule provided for mills ("reduction works other than smelters") called for the "name, location, and character of establish- ment to which the product was sold or shipped for final treatment." A similar inquiry was inserted in tlie special schedules addressed to smelters. These in(jairies were intended to trace the product from the producer to the consumer, as well as to guard against duplica- tions in cases where the same product was successively treated by different estaldishments. Only 4 mines failed to answer the inquiry. The total production of those mines was i.57 tons of ore, containing 2u,60-± pounds of copper, having a gross value of $2,21ii; in a total production of copper the gross value of which exceeded §70,000,0(io, this is a negligible quantity. Copper ore mined in the United States is e\Tiitually converted into metallic copper in this countrj-, with the exception of a small quantity exported in the shape of matte. Matte (called also "regulus") is a semi- metallic product obtained from ore ])y fusion; it eon- tains from 2.5 to 70 per cent of copper and is blown by further fusion to metallic copper. A portion of the ore was thus concentrated at local matte smelters and shipped for further treatment to other smelters which produce pig copper. The total line copper contents of matte shipped, according to reports received at the Bureau of the Census, amounted to 43,339,268 pounds. Of this quantity, 6,717,594 pounds were shipped to New York brokers for export; 13,325,690 pounds were traced from the matte smelters to the plants where the matte was converted into metal- lic copper; 22,977,984 pounds were reported by copper smelters as the contents of purchased matte, the pro- ducers of the matte failing to report; and 319,000 pounds were reported by shippers, the destination of the matte not being stated. The copper contents of the matte, with the exception of the 13,326,690 pounds wdiich were reported by both shippers and buj'ers. must be included in the total out- put of copper. The 319,000 pounds rei)orted only by shippers were either intended for export, or thev may have been duplicated in the report of some other smelter. Compared with the total production of the United States, the error would amount to only tive- hundredths of 1 per cent. The production of matte and metallic copper, as re- ported ])y smelters, is shown in the statement l)elow. The Lake Superior ores were smelted at the following works: Tlie output of the Calumet and Hecla ^Mining Company and the Quincy Mining Company at their own smelters, from which reports were secured; the mineral from all other mines was treated by the Quincy Mining Company and by the Lake Superior Smelting Company, at Hancock, !Mich. No report was secured from the latter. The copper product of Lake Superior ores has, therefoi-e, been taken from the reports of the Michigan mining companies, including the two above named, which had tlieir own smelters. Some copper was produced l)y lead smelters engaged principally in the treatment of gold and silver bearing- ores; the (piantity reported by them is shown separately in the following statement: Frodiirlioii of iiirloUic ropjh-r mid inaltc in tlie Uiiiled Slolrs: 190-^.

It appears that the value of the production of the mines bore no close relation to the area of mineral lands owned or leased. Still the averagfe value of production per mine increased with the increase in the area of min- eral lands owned up to 5,000 acres, though not in the same ratio. The average value of production per acre decreased as the area increased and the three largest owners were among the smallest producers. It is probable that while the smaller properties were under active operation the larger were awaiting development.

Compared with the output of the copper mines of the United States, the production of the I'nited Copper Company constituted 4.6 per cent of the total gross value, or 4.8 per cent of the fine cojDper contents. An important group of mines was represented by 7 Michigan companies, which, though maintaining a sepa- ' rate corporate existence, were united under a common management through the ownership of the stock b_v the ! same group of stockholders. These were the Winona Copper Company, the Wolverine Copper Mining Com- pany, the Mohawk Mining Company, the Atlantic Min- ing Company, the Baltic Mining Company, the Michigan Copper Company, and the Champion Copper Company. The total output of these companies, as shown in their published reports, yielded 25.237,594 pounds of fine copper having a gross value of $2,992,335, and consti- tuted 4 per cent of the fine copper contents, or 3.8 per cent of the gross value reported at the census f)f 190i! for all copper mines.

This list is not exhaustive; it does not include the United Verde Copper Compcany of Arizona and the Colusa-Parrott Copper Company of Montana, which are controlled bj^ the same interests, and probably some other mines for which there are no available data. The properties enumerated in the preceding statement contribute two-thirds of the output of the United States. The possibilities for further centralization are indi- cated by the location of the general offices of the mining companies. Of the Hi mines, 4:9 had their offices in the East — 31 in New York and 18 in Boston. The output of these mines aggregated 4H3.1i.5,212 pounds of copper out of a total output of 639,033,392 pounds; that is, 72 per cent of the production of the United States. During the years 1900, 1901. and 1902, the output of the principal copper producers was handled by a joint selling agency — the United Metals Selling Com- pany. This company was organized on -Tanuary 29, 1900, and included among its incorporators two repre- sentatives of interests identified with the Amalgamated Copper Company. Its patronage, however, was not conhned to that company alone. The company's charges were from 1.5 to 2.5 per cent for selling cop- per. Its total sales for 1902 were estimated hj- the Boston News Bureau at 51:5,000,000 pounds,^ which amounted to 83 per cent of the output of refined copper for the year, as estimated bv the United States Geological Survey. In 1892 an association of cof)per producers, known as the American Producers' Association, was formed. It represented the following mines: Montana district, those of the Amalgamated Copper Company; Arizona district — Verde, Arizona, Queen, Detroit, Dominion; Lake Superior district — Calumet, Tamarack. Quincy, Osceola, Atlantic, Franklin, Tamarack, jr., Kearsarge, Wolverine, and Central.^ Other companies joined the association subsequent to the date on which that list was compiled.' The association received from its members reports of the production of copper, which were com- piled and published monthly.

Early in 1903 large producing interests withdrew from the American Association, declining to furnish statistics, so that the monthly compilations have ceased. It is worthjr of note that the centralizing tendency in the o23eration of copper mines has been accompanied by a growing decentralization of property interests.

Production on a small scale. — As may be inferred f rom.the degree of concentration shown above, the day of copper mining on a small scale is past. A survival of old time methods was presented by 3 mines operated by waterpower. The more mod(>rn small gas or gaso- liiue engine enabled 12 other mines to conduct opera- tions on a small scale. A summary of these 15 mines, using waterpower or gas exclusively, is presented in the following table: Table 30. — Summar\j of mines using only water wheels, nr gas or gasoline engines: 1902.

The ore was exceptionally rich, yielding 10.4 per cent of tine, copjx'i-. Tlie avei'age price realized per pound of copper was 9.7 cents, which brought i|^22.ol: per ton of ci-u(le ore. The average cost of reduction amounted to COPPER. 491 f8.39 pel' ton, which left $13.65 per ton as vahie at mine, whereas the gross vahie of all copper ores mined and treated in the United States averaged only $(;.79 per ton. It is probable that it was only the exception- ally high grade of the ore that made mining on so small a scale possible. The worWa production and the 'world's copper mar- Jcet. — The United States is to-diiy the chief producer of cojjper in the world; nearly two-thirds of the world's output in 1902 was furnished by the United States.

As shown by the preceding table. North and South America, since 1883, have been the chief source of the world's .supply of copper. While the production of South America has declined, North America as a copper producer has, since 1892, overshadowed the rest of the world. Since 189.5 the mines of the United States alone have furnished more than one-half of the world's copper. Amon^ European producers the Iberian peninsula held the tirst place. Prior to 1882 its output exceeded the production of the United States, and, in 1882, both countries were on the same level, but within the follow- ing twenty years the production of Spain and Portugal increased by only aliout 25 per cent, while the produc- tion of the United States in 1902 was more than seven times as large as it was twentv vears before. 492 MINES AND QUARRIES. Mexico, which prior to 1894 was but a small factor in tlie worlcl\s production of copper, has .since that year more than trebled its output and gained third place among- the copper producing- rountries. Next after Mexico was Japan, which since 1890 has doul)led its output, and Australia, whose progress has been still more rapid. Germany ha.s shown no appreci- able gains since 1896, and has been outranked by Mexico and Australia. In the table which follows, the refined copper product of smelters and refineries of all countries since 1889, as compiled by the Metallgesellschaft and Metallurgische Gesellschaft A.-G., is compared with the copper con- tents of the output of all copper mines, as compiled bj^ Henry R.

As the difference is less than 1 per cent, the estimate of Henry R. Mer ton & Co., Ltd., is retained for the sake of comparison. The variations between the output of mines and smelters have been confined within narrow limits, viz, between 3.7 per cent above and ?>.?> per cent below the mine output. This close agreement is due to the fact that copper is mostly mined and smelted by the same producers; either quantity' may therefore be used for comparisons. DErADE.

A study of the table shows that during the first two decades of the past century the production of copper remained practit^all}^ stationary. From 1820 to 1880 the average yearly production more than doubled once in every twenty years. Within the last two decades of the century the annual average production more than trebled, increasing from 118,900 tons during the years from 1871 to 1880 to 370,890 tons from 1891 to 1900. The annual average output from 1881 to 1890 exceeded the average for the preceding decade by 118,439 tons, i. e., by 99. H per cent, and the annual average for the years from 1891 to 1900 showed an increase over the preceding decade amounting to 133,551 tons, or 56.3 per cent. Though the increase in production during the last decade was absolutely greater than during the preceding period, yet owing to the enlarged volume of production the relative increase appears smaller. The extraordinary progress of copper mining within the last two decades was stimulati^d by the rapid exten- sion of the u.ses of electricity to all branches of in- dustry. The United States has Iteen the chief factor in this progress. The production of the United States increased from 1879 to 1902 more than twelvefold. The share of the United States in the progress of copper mining is shown in the following comparative summarj' bj^ quadrennial periods: T,\BLE 34.— OUTPT'T OF COPT'EK MIXES OF THE UNITED STATES AND OTHER COUNTRIES, BY QUADRENNIAL PERIODS: 1.S79 TO 1902.'

Mcrli CUPPEK 498 Up to the period from 1895 to 1898 the United States wu.s rapidly gaining- over ail other countries. From 1887 to 1891 practicall_v all the increase in the world's production of copper came from the United States. During the j'ears from 1895 to 1898 the United States outranked all other countries. During the last period, closed by the census year 1902, the production of the United States maintained its rate of growth. l>ut min- ing in other countries took on a new life under the stimulus of high prices, as will be shown l)elow, and the increase in their output nearh' reached that of the United States. In Table 35 the world's production and consumption of copper are shown since the year 1895, when the United States surpassed the total production of all other countries. All countries are arranged in two classes: (1) Those whose domestic consumption of re- fined copper exceeded the output of their own mines, and (2) those whose mines produced more than was consumed at home. E'or the sake of l)revity, the former are designated as "importing countries" and the latter as "exporting countries." It must be understood, however, that some of the countries designated here as "importing'' also exj^orted considerable quantities of copper, while those desig- nated as "exporting" may have imported copper oie, matte, etc., to be later reexported as refined copper. In calculating the domestic consumption foi- each coini- try its imports are added to its production, and its exports are deducted from the total; the increase oi- decrea,se of the stocks of cf^pper fronj year to year is also taken into account wherever ascertainable. The estimate of domestic consumption which is arri\cd at in this manner represents the supply of copper a\aila- ble for domestic consumption, liut is not necessarily identical with the quantity actually consumed in manu- factui'es for which copper serves as material. In Table 35 the column headed "product of mines'" represents only the production of copper from domes- tic ores, as reported by Henry K. Merton & Co., Ltd.: the column "consumption" rt'presents the supply available from all sources for domestic consumption, as computed by the Metallgesellschaft and Metallur- gische Gesellschaft A.-G.; the "net demand for im- ported copper" in the list of importing countries and. the "net supply available for export" in the list of exporting countries represents, in each case, the differ- ence between the totals of the two columns just men- tioned. The talile thus shows, on the one hand, the share contributed by each copper mining country to the world's supply of copper, and on the other hand the demand for unmanufactured copper directly exercised by the manufacturing industries of each country.

More than one-half of the copper mined was exported for consumption to other countries. With the exception of the United States, the principal producers of copper had practical!}' no market for it at home. The United States, though holding the first place among the con- sumers of copper, was also largely dependent upon the foreign market for the .sale of the product of its mines. There is a difference amounting from a fraction of 1 per cent to over 10 per cent between the total net sup- ply available for export and the total net demand for imported copper. The variance is due in part to the well-known disagreement between export and import sta- tistics and partly to the fact that the resmelting of old copper enters into the calculation of the consumption for some countries. On the whole, the copper mines of the United States have since ls!(5 supplied over one-third of the demand for imported copper, as shown in the following table: Table .37- — ('imsuniption of copper in ini/iorting countries and exports of doiin-xtic Clipper front the J'nited States: 1S95 to 1903.

The precedino; table clearly shows the place of each producing country in the world's copper trade. Begin- ning with the year 18!t6, the United States showed a growing excess of exports to Europe over its domestic supply, wliereas in all other coppei' producing coiuiti'ies the snpph' available for export exceeded the direct exports to Europe. The t'xcess of the exports from the United States in 19ul and 1902 was very near the surplus of all other countries, after deducting their direct exports to Europe. These tigures demonstrate that the United States has within late years gained control of the export trade of non-European copper producing countries. A closer study of the statistics shows that the direct exports to Europe from Canada and ]Mexico have fallen otf slightly, while the supply of copper available in these countries foi' export has more than treVjled since 189.5. All this copper found its wa}' to the United States, to be reexported to Europe. The direct exports to Europe from Canada and Mexico are but a minor portion of their total copper exports. The United States has also a fair share of the copper trade of .lapan, Australia, and Chile, though these counti'ies for the most part maintain direct relations with Europe. The share of the United States in each of the princi- pal European copper markets, namely, Great Britain, Germany, and France, is shown in the following table. The imports reported b}' these countries from the United States represent actual exports from this country, both of domestic and foreign copper.

Germany was the largest European consumer of American copper. The German copper market de- pended upon the United States for more than one-half of its supply, the balance being furnished by the Ger- man mines and by imports from other countries. The second place among the consumers of American copper was held by Great Britain; the position of American copper in the English market was important, vet far from dominant. The French market has, since isittl, developed a large demand for American copper; in VM)2 two-thirds of the copper consumed in France was im- ported h-om the United States. Iiitefujitloiiol orr/a/iiisatioii hhhhk/ jiroducirK. — The degree of concentration which has been noted in the United States was also cliarticteristic of the copper mining industry in other countries. In Spain the two largest mines, the Rio Tinto and the Tharsis, were operated l)y English corporations, the former being controlled by the Rothschild interests.' The Rio Tinto produced in ISHil, 79,279,520 pounds of tine copper, and the Tharsis l(),(i3-l,-l:97 pounds of tine copper in matte and bullion," and the latter produced in 1901. 24,153,197 pounds.* The combined production of these two mines represented two-thirds of the total output of Mexico. In Germany the Mansfeld mines produced in 1901 42,0(17.200 pounds of copper, which was practically all the copper produced in Germany. The concentration of the copper mining industry imder the control of a limited number of companies facilitated organization among them. The first attempt at organization was the Secretan syndicate, which was formed in Paris in the fall of 18S7, with the object of improving the i)rice of copper. The syndicate was organized with a capital stock of 100,000,000 francs, di- vided into shares of 1,000,000 francs each. In October, 18S7, tine copper was quoted in London at from =€39 to i;40 per ton. The syndicate made contracts with min- ing companies in all parts of the world for their entire supply at prices ranging from £68 to £7o per ton.

The movements of the solid line in Diagram Ha and of the dotted line in Diagram II indicate that the high prices of 1899 to 1901 stimulated production. In order to maintain a firm price it was necessary to reduce exports, which resulted in an increase of the suppi}' available for domestic consumption. The relation between the available supply and the actual demand for domestic consumption in 1900, 1901, and 1902 is shown in the data published by the United States Geological Survey. The available supply is computed by adding the production of domestic copper and imports of copper in ore, matte, bars, etc., entered for consumption, and b}' deducting from the sum the exports of copper. The demand, or estimated con- sumption, is obtained by deducting the increase in pro- ducers' stocks from the available supply, or by adding to it the decrease in producers' stocks. The following statement shows the relation of supply and demand to prices: " Supply awl deniand and prices in the United. Slates: 1.900 to 190J. YEAR. Supply (pounds). Demand (pounds).

T.'i, page 1314. In 1900 the copper producers managed to keep the supply close to the limits of demand; the price was maintained between 16 and ITi cents per pound. In 1901 the domestic demand remained almost stationary, but the supply increased enormously, which was due to a reduction in the foreign exports. In the face of this increased supply the price was for fully eleven months held at the .same level as during the year before, and only in December, 1901, was it reduced to 12|- cents. Except for a brief slump to lOi^ cents in Janu- ary, 1902, and a rise to 13^ in February, the price dur- ing the year fluctuated between 11^ and 12f cents, and at these prices nearly all of the surplus was absorbed in the domestic market; the demand in 1902 exceeded by 14 per cent that of the previous 3'ear. The effect of high prices upon the American trade with Europe is shown in Diagram III. The solid line representing the net demand for imported copper and the dotted line representing the share supplied liy the United States run almost parallel. An increase of the demand in Europe, as here represented, increases im- ports from the United States; a slackening of the demand reduces imports from the United States.

The rise of the demand and a parallel rise of the imports from America in 19(t2 are accom- panied by a decline in the imports from other sources. A comparison of the totals for the quadrennial periods 1895 to 1898 and 1899 to 190-2 (see Table 37) shows that while the European deinand rose from 99t;I,.556 to l,0t:>l:,082 long tons, the imports from the United States fell from 389,410 to 319,033 tons. The effect of the latest price movement ujjon the American export trade was not alike in the principal European markets. Diagrams IV and IVa illustrate the correlation be- tween the Loudon price, the consumption in Great Britain, and the imports from the United States and other countries^ The results appear to be the same as shown for Europe as a whole. In the French market the decline of American imports, as shown in Diagram V, created somewhat of an increase in the imports from other countries, not, however, corresponding to the shortage of the former. Diagram VI shows for Ger- many a parallel movement between the consumption of that country and the imports from the United States; yet the decline of American imports in 1901 did not increase the imports from other countries. While the effect of high prices from 1899 to 1901 upon the export trade may appear unfavorable, yet it was declared by the Amalgamated Copper Company, in its official statement, that "the portion of the cop- per which has been sold has realized a larger profit than would have been realized had all the copper which had been produced been sold at a much lower price.'" This view is borne out by the following comparison of the pi'oduction, prices, and dividends for the A'ears 1895 to 1902: Production, jjrtcex, and dividends: 1S95 to 1002. 1895 18% 1897 1898 1899 1900 19IJ1 1902 Production of copper (pounns).

By Isaac A. IIouewich, Ph. D. Gold and silver mines as treated in this chapter em- brace (1) gold washing's, commonly known as placers; (2) deep mines, which jdeld gold and silver bearing ore; and (3) ore dressing and reduction works, commonly known as mills, and operated either in connection with mines or independently. Smelters were classified at the Twelfth Census as manufacturing establishments, and were therefore excluded from the census of mines and quarries. The precious metals being frequently associated in the ore with base metals, a proper classification of mines b3' the character of metals produced is attended with certain dilBculties and must perforce appear artificial. Thus, from a minei'alogical or metallurgical point of view, an ore assaying .50 pounds of copper to the short ton and only 1 ounce of gold is a copper ore, whereas from a commercial standpoint it is a gold ore, since the value of the 1 ounce of gold is about three times the value of the copper contained in the ore. The criterion must be determined by the object of the classification. The object of an industrial census being primarily the study of economic conditions, the classi- fication of industries must be based upon an economic test. The product of a mine is accordingly defined here as a gold and silver ore whenever the precious metals con- stitute the principal elements of its comnaercial value. The statistics relative to the mining of copper ores car- rying small values in gold and silver are presented, together with those for other copper ores. Argentif- erous iron ores, valued chiefly as fluxing material, though carrying small quantities of silver, are classed with iron ores. This rule, like any other, is not without exceptions. The value of argentiferous lead ores follows the fluc- tuations in the market prices of silver and lead. The price of silver in 1902 was the lowest in many j-ears. As a result, some mines, whose product at the prices ruling in 19()1 was regarded as silver ore, realized in 1902 less for the silver than for the lead contents of their ore. Many more mines, which at the previous censuses were classed as silver mines, would now have to be considered lead mines, if judged by the relative values of the silver and lead contents of their ores. Such a classification would obviously be purely acci- dental and would destroy the value of all comparisons with the results of previous censuses. It was, therefore, deemed necessary to include all argentiferous lead mines among gold and silver mines. There was, furthermore, a very numerous class of mines whose operations in 1902 were confined to devel- opment work. Any classification of such mines by the character of the ore in sight in advance of actual pro- duction is of necessitj^ arbitrary. Though the work may at present be pursued with the prospect of finding gold and silver in paying quantities, many of these mines, in the light of past experience, will develop into copper, iron, or zinc mines. Yet the commercial na- ture of the investment impresses all such ventures with the character of gold and silver mines. Census statistics of the gold and silver industry from 1860 to 1902 are summarized in the following table: (.509) 510 MINES AND QUARRIES. Table 1.— COMPARATIVE SUMMARY : 1860 TO 1902.

The product included 31,797,474 ounces of silver, which were reported at coining value. For the purpose of comparison the value has been reduced to commercial value, at the rate of 81.134 per ounce fine, which was the average for the vear 1879 and 1.880. The total value reported at the Tenth Census was 879,179.798. Few reliable compixrison.s can be based upon the tig- iires summarized in Table l.a.s the method of collecting and presenting the data varied from census to census. The statistics for 1889 include those for mines at which only development work was done. This is prob- ably true of the previous Census reports. The totals for 1902 were therefore summarized to show also the statistics of mines reporting development work only. Devdopment i€orl\ — In Table 1 is shown the extent of development work done in mines from which no pro- duction was reported. This kind of work was generally prosecuted to some extent in producing mines as well, but was always reported as a part of the ordinary min- ing expenses. In many cases the account was kept separately; where it was not, no separate report could be made, for the operators were unable to estimate the cost with any degree of accurac3'. The total amount expended by regular producers, as far as reported, was $4,683,929. There were, moreover, a number of mines the expenditures for which largely exceeded the re- ceipts. In some instances this may have been due to a poor grade of oi-e; in others to unfavorable conditions which made mining unprofitable. In most cases, how- ever, an examination of the mine reports disclosed no difference in the grade of ore or the charges for treat- ment and freight as compared with other producing mines of the same district; the exces.s of expenditures over returns was therefore presumably due to outlays for development. All such reports were classified sep- arately. This classiKcation was not extended, however, to mines combined with mills, for in such cases heavy expenditures might have been incurred for mill equip- ment and construction work other than development. A summary of such mines, distinguished as ''develop- ing and producing," is presented in the following table, in parallel columns with data relating to regular pro- ducers, designated as "productive:" T.VBLE 2. — (Joinpuratlfi; mammary of productive and of developing and producing mines vithoul mill connection in the United States : 1902.

There are few mines which represent one original location; most of the mining properties represent "groups" of mines, which wan-e at some time past operated as independent undertakings, but have since been united, by purchase, lease, or otherwise, under one management. The identit}- of some of these mines may still be preserved; in most cases, however, their accounts are not segregated, or are only imperfectly segregated, on the books of the present owners. Thus GOLD AND SILVER. 511 some operators will make a separate report for each mine, while others will make oue report for the group, though the difference between the properties may be in the system of bookkeeping rather tlian in mining con- ditions. Where a mine was operated by a lessee a report was required from liim. But in some mining districts it is customar}^ to apportion the mine, in small allotments or "blocks," among a number of miners working on a roj^alty and designated as "lessees." The shifting- character of this class of "lessees" precluded a com- plete canvass of their operations; in all such cases the owner of the mining property was required to make one report covering all his lessees. In placer mining there arc numerous prospectors and gold seekers moving from place to place who can not be reached bj' a census of mines. These miners are not included in the number of operators, but their pro- duction was ascertained from other reliable sources and is included. A number of mines changed hands in the course of the year, and separate reports were received from each of the parties by wliom the mine was successively operated. While the location and equipment of the mine remained the same, j-et the character of owner- ship, capitalization, method of treatment of the ore, etc., in some cases had undergone a change; a combi- nation of heterogeneous reports, made b}- different operators, into one, for the mines, was impracticable. ]Mills operated in connection with mines were bj- some operators reported separatel3^ and by others wei'e in- cluded in the mine report. In order to meet all these varying conditions it was deemed advisable to accept every individual report as a unit of enumeration, except that reduction works when connected with mines were in all cases counted as a part of the mine equipment. The number of mines and the number of operators as given in the tables are, therefore, identical. The total number of active mines, as here defined, was 2,992. There were, furthermore, 3,2.52 mines which were operated in 1902 but reported no production, the work being confined to the development of the mines. This does not include mining prospects upon which "assess- ment work" was done, i. e., the quantity of labor re- quired by law as a condition for holding title to the mining claim. The scope of the census of mines and quarries did not comprise a canvass of mining pros- pects, but a number of mining properties locall}' re- ported as active or in the development stage proved upon inquiry to be mere prospects. The number of claims which were thus reported and the number of their owners are shown in the following table, by states and territories, arranged according to the number of claims reported: Table 3. — Mining prospects npon which assessment work viasdone, hy stales and territories: 190S.

The lowest rank among the AVestern states was held by Montana, which reported only 17 pros- pectors. Prospecting in the Southern states was excep- tional. The total number of claims reported exceeded but little the number of owners. There were in all 1:3 owners reporting more than one claim each, and the total number of claims held hj them was 119; the highest number of claims held by one owner was 32, and was reported from Oregon. The following table shows the distribution of owners by the number of claims held: Table 4. — Distribution of mining prospectors hy narnher of claims held: 1902.

This number embraces only mines which had been pre- viously reputed as active, and the owners of which were therefore either communicated with bj^ mail or visited by special agents. There were doubtless man}- more mines which had at some time been operated, but were idle in 1902. Character of oivnerKhlj). — The majority of gold and 512 MINES AND QUARRIES. silver mining enterprises in 1903 did not have an incor- porated form of organization. A distinction is to be noted in this respect between deep mines and those in the development stage on the one hand and placers on the other hand; while about one-half of the former were operated b_v incorporated companies, the owners of only about one-sixth of the latter were incorporated. An- other noteworthy fact is that the majority of incorpo- rated companies were engaged exclusively in develop- ment work, whereas the majority of firms and individuals operated producing mines. It would seem, therefore, that the corporate form of ownership is more favorable to the dev^elopment of modern mines. The following- table presents the classification of all mines by charac- ter of ownership: Table 5. — All mines, classified by character of onmemhip: 190S. Total. Incorpo- pany. , ludi- vidual.

Among mines reporting development work only, the corporate form predominated in Arizona, Nevada, Oregon, South Dakota, Utah, Washington, and Wyoming.

The preceding table sliows that the corporate form of ownership, though adopted by only a little over one- third of all active operators, figured in more than four-fifths of the total output of the mines and showed the largest output per mine. Both firms and individ- uals belonged to the small type of producers. Other forms of organization represented but three-tenths of 1 per cent of the total output. The corporate form of ownership played a more important part in deep than in placer mining, the ownei'ship of about one-half of all deep mines, contributing over five-sixths of the product, being that of incorporated companies, whereas the number of incorporated owners of placer mines was less than one-sixth of all placer mines, and their product was but about one-half of the total for all mines.

A summar\' of dividend and noudividcnd payiiie- com- j panics is presented in Table 11. It must be borne in mind that the payment of dividends in a given year is not in- ! dicative of net profits earned during the same year, for dividends may be paid from the accumulated surplus of former years. Among the lo(.> companies wdiich paid dividends w'ere 15 wliose e.vponditures, mostly for devel- Table 11.— SUM.MARY for DIVIDEND P.iYINGAXD NOXDIV opmeiit work, during the year exceeded their receipts. The dividends declared by these companies aggregated $H15.14'.i, out of a total product valued at §l,05t»,617. It is obvious that thesi> dividends had no relation to the earnings of the year. Likewise, the failure to declare a dividend docs not nocessaril}- show actual loss. Earn- ings ma}' have been invested in development work, in new e((uipment of plants, in acquiring new property, etc. It is fair to assume, however, that generally the payment of di\'idcnds is a sign of successful opera- tion. To facilitate coruparisons, all incorporated com- panies arc arranged under three heads: (1) Dividend paj'ing — that is, companies that paid dividends during 1902; ('•^) nondividend paying companies owning pro- ductive mines; (3) developing and producing companies, meaning companies with wdiich production was uterely incidental to development work, expenditures being- in < xcess of receipts.

The preceding table shows that the dividend paying companies contrihuted over one-half of the output. Taking deep mines alone and eliminating ronipanies with which production was merely' incidental t(_) devcdop- ment work, it will he observed that the grade of ore mined by dividend paying companies was worth $14 p(>r ton, whereas the ore mined b}' nondividend paying companies was worth only $7. Empl(jijee>< and imijex. — The average number of wage- earners employed in gold and silver mines was 47, '.M);") men. of whom 3.3, 8'2] were employed in deep mines, 2,321 in placer mines, and ll,7ti3 in mines re])orting only development work. Their total wages amounted to $4T,t>.58,r7fi. In any analysis of these figures it nmst be l)orne in mind that the above number of wage-earners is an average, comjiuted on the Ijasis of 3i»0 working days, and is not identical with the actual number of persons who earned the amount of wages reported. The average per wage-earner accordingly represents the cost of one man's labor to the employer, which is not identical with the average annual earnings. For the purpose of estimating the earning capacity of wage- earners, average daily rates should ))e consulted.

As shown bv the above table, practically all of the wage-earners in gold and silver mines received $2 per day or over. When the figures for the several classes are combined it is found that IK^.o per cent of the total number received between $2 and $4.24. The statistics .show a very large concentration of the wage-earners in three rate group.s, as follows: 13.9 per cent of the total number in group $2..5i) to $2.74, 33.4 per cent in group S3 to $3.24, and 21 per cent in group $3.. Mi to $3.74. Most of the employees included in these groups probably received the e\'en rates $2. .50, $3 or $3.r)() per day. More than half of the wage-earnci's were returned as miners. Their wages ranged between nai'row limits, 87.2 per cent of the total number ha\'ing beeri ]iai(l from $2. .50 to $3.74 per day. In the rate grou]) $1! to $3.24 arc included 3t) per cent of all the miners i-epoi'ted. There were also 3,8(14 men returned as miners' helpers, about one-seventh tlic number of miners. The rates of pa}' for these helpei's were somewhat lower than those paid to the miners. The rates paid to enginrrrs, niadiinisis, and other mechanics were higher than those of the other wage- eai'uers; 112.8 per cent of the engineers and 86.;> per cent of the machinists and other mechanics received $3 per day or o\er. Xi $1 or more the respective pro- portions were 42.2 and 37. <> per cent. The rates for firemen were somewhat lower, a much greater propor- tion of them having been paid less than $3 per day. The range of wages for 7H.l per cent of the firemen was from $2.5(» to $3.74 per day. There were 574 tim- bermen and track layers reported, all but 8 of whom re- ceived $2..5n pel- day or more. The daily rates for the great ])art of these employees were prol.)ably $3 or $3.50, as 33.3 per cent of them are included in the group $3 to $3.24, and 36. H per cent in the group $3.50 to $3.74. The bo\'s under 1(1 years employed in gold and silver mines nimibered only 33, and constituted h^ss than one- tenth of 1 per cent of the total numl.)er of wage-earners. Five of these boys received less than 50 cents a day, and the rest of them were paid between 50 cents and $2.24.

The nites of pay for the.se employees were somewhat lower thaii those for the wat>'e-(>arners already considei'ed, about one-tifth (21. S per cent) iiaviiiu- lieen paid less than $2..^0 per day. The majority of tliem, however, received at least it^:^.5() and a large proj)ortion received considerahly more than that.

Of the states for which statistics are presented sep- arately in the abo\-e table, rates were highest in Mon- tana. Practically all of the wage-earners in that state received at least $3 per day, and 82.3 per cent of them were paid $3.50 or over. In the .single group $3.50 to $3.74 are included 65.8 per cent of all the wage-earn- ers and a large proportion of these probably received exactly $3.5(» per day. In South Dakota, Idaho, and Nevada the rates paid were somewhat less than in Montana, but between the three states there was, on the whole, comparatively little difference. At first glance it would seem that of the three states rates were highest in Nevada, for that state shows an exceptionally large proportion of wage-earners at $4 and over. It will be noticed, however, that the proportions at $3 or more and at $3.50 or more are greater in South Dakota and Idaho than in Nevada, while the proportions receiving less than $3 are smaller. Of the wage-earners in South Dakota, 53.9 per cent are imduded in the single group $3.5i» to $3.74, and 31 p(M- cent in the group $3 to $3.24. In Idaho 8(3 per cent are included in three 52U ]\[INKS AND QUAKRIP:S. consecutive groups, constituting; the ranoe froiii ^y> to $3.74 per day. There was a gTeater divergeiu'e in the wages paid in Nevada, the group including the great- est number of employees lieing that from >:>'> to >t^H.i!4-, and the one including the next largest numl>ei' ))eing that from $4 to *4.2-l-. Following the states above mentioned in the oi'dei' of the rates paid come Coloratlo and Arizona. In these two states, also, there was on the whole com]jaratively little difference in wages. In Colorado the range of wage.s for 94.2 per cent of the wage-earuei's was from S'2.50 to S-i.2-4 per day, -48. o per cent l.ieing included in the single grouj) §2 to ¥3.24. In Arizona the wage- earners were distributed in smaller groups over a wider range. Practically all of them (i.iT.l per cent) received between $1..5i} and §4.24 per day. The great- est concentration in Arizona is at §3 to §3.5(.) i)er day, 23.7 per cent l)eing included in group $3 to $3.24 and 33.4 per cent in group §3.5ii to $3.74. Of the states which employed, on the average, more than one thousand wage-earners, California and Utah show the lowest rates. In each of these states the greater part of the wage-earners received between $2.50 and §3.24 per day, the proportion included between those limits being- 7('i.4 per cent f(U' California and 78.3 per cent for Utah. It will be noticed that the statistics grouped under "all other states and territoi-ies"' include practically all the returns for wage-earners receiving less than $1.50 per daj'. This is due to the inclusion of several Southern states, in which rates of wages were low. Thev reported a comparatively small numl>er of wage- earner.s. The employees at the higher rates included under '"all other states and territories" were prin- cipally in Oregon, New Mexico, and Washington, where rates were approximately the same as in the Western states, for which a separate showing is made in Table 13. In addition to regular wage-earners employed by the day or by the task, there is a special class of labor va- riously designated as "leasers," "block lessees," "triV)- uters," "chloriders," etc. Technically, they "lease" from the operator a block in the mine and '■pav"a stipulated royalty, which \-aries with the richness of the ore; in reality all tlie (jre hoistefl is usually delivered to the operator and marketed hy him, or else it is shipped in his name to the sampler or smelter; the operator retains his royalty, or authorizes the ore buyer to withhold the same, and ])ays to the "lessees" their share of the proceeds. In all cases these woi-kers fur- nish tlieii' mvn mine supplies. While resembling in form an (.)rdinai-v mining lease, tins is in substance a contract of employment on a share of the jii'oduct. The average niimbei- of miners emplo\('(l on a sliai'e of the ])roduit in I'JifZ was I.L'so, and the total com- pensation received by them amounted to §1,452,692, which included the cost of supplies furnished b_y them. This system is in vogue chiefly in Colorado, which re- ported 158 mines worked on shares, with 823 "leaser.s." California liad 27 such mines; Montana, 18; Nevada, 7; Idaho, 3; New Mexico, 3; Arizona, 3; Oregon, 2; and Georgia and North Carolina, 1 each. A summary of mines employing this class of labor i.s presented in the table next following. Deep mines are divided into two groups — those worked on shares only and those employing lioth share and wage workers. There were only 2 jilacer mines reported as having both classes of labor; these 2 mines are therefore omitted from the table. The mines worked exclusively on shares were small. The larger mines where this sys- tem was practiced also employed regular wage-earners. Table 14. — S/iitiin<(ri/ for niliir.^ trorlnl on :<]ian i:i02 DEEP. PLACER. Total. Without wage labor.

The total number of owners so employed in producing mines was reported as 1,495 and the number so engaged in mines under devtdopment was 609. There were in all 5'.»9 producing mines and 2S1 under development which employed no hired labor at all. It must be borne in mind, however, that the census agents were instructed to omit from their canvass mines where less than two wage-earners M'ere employed. The above numbers, therefore, inclufle (jiily ,such mines as were reached by corresi)ondence and those Mdiich were supposed from prcdiminiiry informaticjn to come within the scope of the ctmvass, but were found upon personal iiKjuirv bv special agents to employ no hired labor.

The total amount paid for contract work was $2,16,S,,S61, of which $1,542,771 was paid at mines when; dc'V(dop- ment work alone was prosecuted, and $626,090 at pro- ducing mines. The latter amount was nearly all ex- pended in (le\'elo])ment work, such as tiuineling, shaft sinking, ilrifting, I'unning levels and winzes, etc. Min- ing jji'oper (stoj)ing) was only in two cases reported a,s being doiK! Ijy contract along with dex'elopment work, the total expenditur<> for contract work in these two cases amounting to $46,)S,S,S, I'umping was reported in two cases only, the total amount being insignificant. In a few cases cutting and hauling of wf)od and timlx'r, roadmaking, and Ijuilding and cleaning of ditches wer(; reported, the total expense amounting to $15,414. The number of men employed on contract work could .not always be stated accurately liy mine operators, for the reason that they had no direct control over the men employed by the contractors. Very frequently the number of men to be furnished by the contractor was .-.tipulated in the contract. .Still the time consumed by them in doing the work was in most cases not stated; therefore the number of men could not be re- duced to an annual average basis of 30i) working daj's, and duplications could not be avoided. The same men working in a mining camp on a number of mines suc- cessively were reported by several operators. The total numlier reported for producing mines was 980 men, whereas in mines reporting development work only, the num])er of men emploj-ed by contractors aggregated as many as 5,649. The number of men re- ported in each (dass of mines shows an extreme dispro- portion to the amounts ]:)aid for contract work. It is apparent that in some cases the numlier of men must have been underestimated, whereas in others there were probably many duplications. The several (dasses of labor presented under the head of ''employees and wages"' and "contract work"' com- prise an average of 47,9t(5 regular wage-earners, l,2,sO workers for a share of the product, 2,104 owners doing manual labor, and 6.629 men emploj-ed bj^ contractors. In addition to these, 5,135 prospectors reported 5,519 mining claims, upon which, in compliance with the min- ing laws, the sum of $551,900 ought to have been ex- pended in assessment work. Considering that many mines were operated only at certain seasons and that during a portion of the year the miners had to employ their tinu^ in other industries, it ma}' be conservatively estimated that from 50,0((0 to 6(),00(i men found em- ployment in gold and silver mining. T'nm: III iijirrafiini. — Tables !(), 17, IS, 19, and 20 present a classihcation of producing mines by the num- ber of days in operation, number of shifts employed per day, and nund)er of hours per shift, and a like classihcation of all mills whenever separately reported. For a number of the mills combined with mines only one report was made for l)oth mill and mine, in which c!>se the report was included with the number of mills. There were, as stated on a preceding page, 599 522 MINES AND QUARRIES. mines in which no hii'cd liihor was employed, nut iii- chiding 162 mines wliei-e all miners were woriviny on a share of the produrt, and 2,393 mines and mills witli regular wage-earners. Many of the two former classes failed to report the numhi'rof days and hours in opcra- tit)n. The number of mines repoi'ting the days in op- eration was 2,525, and the number reporting the hours in operation was 2,4:ii4. The total nnnd>er of mines shown in Taltles IS and 19 includes a duplication of 3-1 mines which reported different hours for various classes of emplovees. All other mines reported the same hours for all employees. Table 16. — Xumber nf iniiifx, fUtssificd according to tiiuiibci' iij diu/x in opcrdthiii. III! slides and territories: 1902.

The "material" operated upon in a mine is the rock underground or the gold l:)earing gravel. The inquii'y calling for "total cost of supplies and materials of all kinds used during the year" at the mine contained the following explanatory note: "The cost of the following materials should here- ported under this inquiry: Lumber and timber used for repairs, mine supports, track ties, cars, and for all other purposes; iron and steel for blacksmithing: rails, frogs, sleepers, etc., for tracks and repairs; parts t)f machinery and tools used for renewals and repairs; explosives, water for boilers and for other purposes; fuel, illuminating and lubricating oils, machinery sup- plies, etc." All the items hei'e enumerated come strictly under the definition of "supplies." The "material" treated at the mills is the ore which comes from the mine. It is not customary in mining bookkeeping to charge the mill with the value of the ore brought from the mine. In the schedule relating to " reduction works, other than smelters," there were two separate inquiries, one relating to "materials," another to "supplies." The former called for a statement of the "character of ma- terials used, whether ore, tailings, or other materials." and was confined to "materials bought in l'..)()2." The amount reported in answer to this inquiry is not in- cluded in the cost of "supplies and materials" but is given elsewhere as a separate item. The explanatory note to the inquiry relating to mill "supplies" enumerated: "Shoes, dies, screens, plates, and other parts of machineiy and tools used for re- newals and repairs; (jnicksilver. cyanide of potassium, lumber, iron, steel, oil, fuel, water, etc." The total cost of "supplies and materials," as herein defined, was reported as 121,774,846, distributed as follows: Producing mines, deep, |il.5,9()S,782; placer, $790,986; developing mines, 1.5,075,077. The item, "miscellaneous expenses," includes rent and roviilties of all descriptions, " taxes, insurance, in- terest, advertising, office supplies, law expenses, injuries and damages, telegraph and telephone service, gas, and all other sundries not re^Dorted elsewhere." The total amount of miscellaneous expenses of pro- ducing mines was f.i (",529, of which $1, -419, 155 was reported as rents and royalties of all descriptions for mines, and $3,93S,;:]74 for all other mine expenses and miscellaneous mill expenses; the latter item includes the sum of $4,244 paid by custom mills as I'oyalties for the pi'ivilege of reworking old tailings. The miscellaneous expenses of developing mines ag- gregated $1,017,356, of which rents and rovalties of all descriptions amounted toonly $71,131. That theamount of rents and royalties paid by this class of mines was so insignificant is in harmonj- with the character of the mines, royalties and rents being as a rule proportionate to the returns of the mine. "Where the mine is not pro- ducing, the labor and expense incurred by the operator in developing the mine are a part consideration for the privilege of working the same. Of the items making up the total royalties ($71,131). the principal expense ($41,916) was for the use of water, and the next largest sum ($16,153) was ex- pended for electric power; other power (air. steam, etc.), cost $2,406; the rents of mines and mineral hinds amounted to $4,528; expenditures on plant and im- provements were $3,572; for tunnel privileges, $843: and rent of office and miscellaneous rents, $1,713. 524 M1NE8 AND QUARRIES.

Koyalties for tunntd privileges were reported as follows: Colorado, ^-t'j.H.^-i: Ne\'ada. $12,482; Utah, $T,2t;fi; all other states, is5S0. The most of the paj'ments for water rents, $210.

The amount e.xpended for rent of (deetric power was $215,802, of which $12s,(iT7 was reported from California and $87,725 from Colorado. Th(^ rent of other power was exceptional. The royalties do not include those charged to so-called " block lessees," " tributers,"' etc., who made no reports to the census. A\^here the mine was worked iiy regular wage-earners as well as bj' trilniters the amount cliarged against the latter as roj'alties could not be segregated. But where this was the onU class of labor employed in mining the amount charged as roj-alties can be ascer- tained by deducting the amount paid to the lessees from the total value realized for the ore at the mine. Mineral laii(h. — The primary distinction between mining and manufacturing is that in the latter only capital and labor are factors, while in the former industry there are three factors of production, viz, land, capital, and labor. The present census of mines and (piarries is the fir.st in whicli the scope of the inipiiry has in some branches been extended to the ownershii) of mineral lands. Though the special schedule providing for gold, silver, lead, and copi>er mines confined itself to mineral lands, it is probable that in some cases the reports included lands of all descriptions, such as timbering lands, building lots, etc. The acreag(> of mineral lands was reportefl for 5,845 mines, viz: Producing, deep. 1,'..»1P); producing, placer, 84, 0^6. No report of acreage was made for 178 producing, and for 166 developing, mines; the.se constituted 5.5 jjcrcent of the total. Thi' area rei)orted ))y producing mines was 406,001) acres, of which 21'.l,;-i4'.> acres belonged to deep mines and IS6,660 acr(>s to placers: 653,001 acres were reported by mines under development. This shows that the area held for development exceeds by more than one-half th(^ acreag(> of producing mines. The leasing of mineral lands had only a sub(jrdinate part in gold and silver mining. The total area rented was 58,807 acres, 33,259 acres by operators f)f jiroducing mines and 25,548 acres for development. The total ro}-- alties paid for the use of mineral lands amounted to $696,372, of which $46,807 was paid on placers and $649,565 for deep mines. In Table 21 all mines report- ing acreage are arranged b}' the area owned and leased, by the character of mine, and bv states and territories.

Table 33. — ('(inipiirlxoii of the ore at wliich the total vahie ot the shipment is cdm- patetL The freiglit cliarges for carrying' the ore fi'oni the mine to tlie worlds are home hy the mine operator. Usually the freight is paid by the l)uyer and deducted from the agreed value of the shipnuMit, and a check for the balance is delivered to the mine operator. TJuis, as a rule, the value of the ore at mine is not a .speculative quantity, but an amount appearing on the books of the mine operator. \\'liere the mine is situated at a dis- tance from a railroad station, the o],)erator usually iiauls the oi'e to th(> station l)y his own teams, and the cost of haulage is included in tlie operating expenses. Where a number of mines are centered in one camp, haulage is more frequently done by teamsters who make a specialty of hauling ore from the mines to the raih\)ad station and bringing Ijack supplies to the mines. Under ordi- nary circumstances the hire per ton will not vary during the 3'ear and can be accurately stated. This is true even if no separate account of it is kept by the operator, in which case the cost of haulage is included in the amount reported for freight. When the ore is of a very low grade, or where the mine is located at a great distance from the railroad station, and the cost of haul- age is paid liy the mine operator, it sometimes happens that the value realized does not repay the cost of ship- ping. A few such cases were reported for liHji^. and the value of the product was shown as a "net loss." The value of bullion when sold to the Ignited States mints or assay offices is determined by assay: gold con- tents are paid for at the coining rate of $2(».t)7 per tine ounce, and the silver contents at a price tixed from time to time bj- the Director of the Mint; a small charge is made for smelting and retining. When liullion is sold to private parties, banks, bullion dealers, etc., it is usually sold at a net price per crude ounce; the differ- ence between the coining value of the tine gold contents and that paid by^ the buver represents the expenses of retining and marketing the bullion, commissions, inter- est, etc. When the bullion is shipped l)V express the cost of expressage is deducted by the Mint and the balance is paid to the depositor of the bullion. Frequently bul- lion is sent l>y registered mail or brought to the Mint or bullion dealer personally ))y the owner. The cost of transportation is insignificant as compared with the value of the bullion, and may be treated as a negligible quantity. Thus the value received by the operator for his bullion always represents the value at his mine or works. The following table shows in detail the manner in which the al)ove-stated total value of the mining product was obtained: T.MiLK .■{.5. — ]'(ijiir nf jii-diliirt lit mini': 1902.

There is a sepa- rate item showing the i)i'oiluct of the treatment of old dumps and tailings. This i-epresents tlie output of mills wliicli operated cx(dusively on old dumps and tail- ings. The treatment of ore from dumps and tailings, which was incidental to the operations of all mills, is included in their total output. The ore and liullion sold b}' custom mills represent only the products of ores purchased by those mills. When the ore was merely treated for a stipulated com- pensation and the dressed ore (concentrate) or bullion was returned to the owner, the amount earned for the treatment of the ore only was considered as belonging to the production of the mill. The value of the ore or liullion itself was not included in the product of the mill, inasmuch as it would have been a duplication of the value received liy the mine owner for his product. Moreover, it was only in exceptional cases that the mill oiierator was able to report the value of such ores, inas- much as his charges were not dependent upon the value of the ore and he had no interest to keep an account of the same. On the contrary, the product of the pur- chased ores was always reported. In order to eliminate duplications, the cost of purchased ores and freight paid on the same are deducted in the preceding state- ment from the total value reported. The increase and decrease of the stock on hand rep- resent the differences between the value of the stock on hand at the beginning and at the close of the year. In accounting for the mining production of a given year these diti'erences must be taken into consideration, inasmuch as the product at'tually sold or treated during the year does not represent the returns for the mining- expenses incurred during the same year. In individual cases the diflerence may be considerable. Th(> value of the increase oi' decrease of stock of ore is necessarilv an estimate. The value was computed at this office, taking as a basis in eat-h case the value reported bv the operator for the marketed ore and assuming the aver- age value per ton of the increase or decrease of stock 532 ^riNES AND QUARRIES. on huiul to luivo ))een the suiiie a.s tluit of tlir luiirkctrd ore. The decrease of stock representcHi ore mined in previous years and raarketed durino- the year I'.Mii!. Thouyh the o-riule of that ore may ha\-e Ixmmi different from that of the ore mined during this year, yet for statistical purposes tlie assumption of one avemge value for all ore treated •nas correct, ^^'here there was an increase of the stock of ore, iiowe\'er, it woidd be often unsafe to assume the average^ value of the ore on the dumps to l)e the same as that of the ore actually sold or treated. The ore may have been sorted and the better grade sold, the ore left on the dumps being of a low grade which it would not pay to ship, or a few test shipments may have been made which did not rep- resent the average grade of ore. In order to guard against such errors no estimate Mas made of the \'alue of the increase of stock whenever the same exceeded the actual quantity sold, unless, upon a comparison of the returns for ore actually sold with the outlay for mining, it appeared probable that more paying ore had been mined than sold and that the ore on hand was merely awaiting treatment. In all doubtful cases inquiries were addressed to the operators, and these, as a rule, were answei'ed promptly and satisfactorily. Nor were any estimates made of the increase of tlu> stock of ore in cases where the mine was equipped with a mill. When the expenses of the lattcu' were not reported separately there was no basis for estimating the cost of milling the ore, and none but the gross value of the same could be estimated; moreover, the fact that the ore was not milled raised the presumption, at least in some cases, that it did not pay to treat it. Thus the value of the increase of stock of ore is probably rather underestimated than overestimated. There were a numljer of small mines, deep and placer, from which no report could be secured. Their outjjut was ascertained from the best a\'ailal)le source's, such as assay offices, local bvdlion dealei-s, and other reliable pei'sons who, through business intercourse' with the minei's, hafl acquired information which enalded them to estimate the output of such mines with reason- able accuracy. These estimates, however, as will be shown later, seem to be ))cl()w the actual production of this class of mines. The value thus com]>uted represents the \'alue of the product of gold and silver mines for IDo^. It must ))e understood that many small operators keep no bof)ks oi- records, and the amounts repoi'ted by them areap])roxi- mations. Bullion co/itrnfy. — As explained above, the bullion contents of the ore were hgui'cd in detail in every set- tlement Ijetween mine operators and ore buyers. The statements I'endei'cd by the latter to the former are, in all well managed mines, ke])t on tile and entered in detail in the books of the company. 'I'he saiuo is done with United States Mint bullion returns. Not in all cases, however, are accounts kept with such accuracy, e\-en in some of tlie largei- mines. In such cases the bullion contents re'poi'ted were of necessity estimated. The approximations, howe\'er, may be taken as reasonably accurate, inasnmch as the ti'eatment charges did not \arv -widely for the same mine, wddle the freight per ton could l)e I'cgarded as a constant ipiantity. In some cases the A'alue alone was ]-eported for each of the metallic elements of the ore; the lunuber of ounces of gold and silver, and the pounds of lead and copper were then computed on the basis of the average value reported in other cases. The total (piantity of gold bullion produced by mills connected with mines was l,(Ui(],.3l5 ounces with a gross value of $34,(i(ii!,.53r), or an average value of '¥i!0.44 per ounce. This was the rate realized by the operator, the difference of iio cents representing the cost of refining and marketing the l)ullion. The gross value of the product of mines coimected with mills includes the sum of §.520,727, which represents net value, the refining charges on the bullion produced not having been reported. At the above average rate the cost of refin- ing the above quantity must have been about $5,2()7, which, being added to the gross value, would increase the production by 2.52 ounces. The quantity is too small to be considered. The munber of tine ounces of gold produced b}' arras- tras was not reported. The gross A'alue, the treatment charges, and the net value alone were repoi'ted. The (juantitv was estimated upon the basis furnished l)y the reports of mines connected with mills. The total value of the ore at the mine includes §-±9.5,6.54 reported from small mines, whose owners could not l)e located, and the product had to be ascertained fi-om the best available sources. The amount so ascertained may in souk^ cases have i'epres(>nted the net value real- ized by the miner for his ore. In others the estimates were apparently based upon the assumption that the \'alues repres(>nted the metallic contents of the ore. The number of tine ounces of gold reptirted apparently represent an estimate at the coining rate of §20. (i7 per ouiu'C of gold, or at the current commercial rate of §20 per ounce, and at the rate of 50 cents per ounce of silver. For all these mines the a\erage rate ]>ei' ounce of gold was ijiirlo. 17, which left about ;5() cents for the cost of refining and marketing. Wherever the estimated value in reality rei)resented net proceeds, this compu- tation resulted in an underestimate of the ([uantitv. A\'here, however, it represented gross value of metallic contents, it resulted in an overestimate of the net value produced. 1 Iowe\'er. the amount is so small in pi'o- portion to the i)roduction of the United States that the ettect of it upon the total product may be regarded as a negligible ([uantit\-.

The argentifei'ous iron ores exenii)lify the difficulties attending eveiy classification. Such of these as contain high values in silver, which permit of their working for that metal, were classed as silver ores. Witli most of these ores, however, their chief value lies in the fluxing qualities of their iron and manganese contents, yet the value received for them by the mine opiM'ator represent.s practicallj' nothing l)ut the value of their silver contents. With the exception of a .small quantity, the disposition of which was not reported, all this ore was sold to the American Smelting and Refining Company, which set- tles for it ill the following manner: I The producer of the ore is paid in full for its silver contents at the New York quotation: the percentages of iron and manganese are added together and the \joy- centage of silica is deducted from the sum. If the ditierence is ecjual to -ii) per cent of the weight of the ore no charge, as a rule, is made for smelting and freight. A bonus is paid for every '"unit" — i. e., 2U pounds — over the 4o per cent basis, usually at f5 cents per "unit" — i. e., three-fourths cent per pound — or a deduc- tion is made at the same rate for every unit short of the 40 per cent basis. The \-alue of the product classed as iron ore is made up as follows: Valilr.

Tennessee, Tc-xas, and Virginia. Coinpiirixmin irltli the rejx'i't <>f the Direcfor of f]i,> Mint. — The Director of the Mint estimates annually, from the records of the United States mints and a.ssay offices and from statements furnished by private refin- eries, the product of refined gold and silver from domestic ores. The methods followed in making these estimates ai'e stated as follows: In estiiiiatintj the ijiild yield nf tlie United States in any given year only that gold is looked njioii as really prodnced that has been retined, maile ready for the market, and the ascertained amount of ilomestic origin (which is c<■ hail to the actual uutput of the mines. The first of these i.-J hasi-d on the amount of golil put upon the market liy private relineries during the year plus the fine gold contained in the unrefined bullion of domestic iiroduction deposited at the mints and assay olhces of the Tnited States plus the pure metal of dcjuiestie production contained in ores, eojiper matte, etc., ex- IH>rted to (itlier countries fur reduction. The second calculation is based on the kimuu disiiositi(.iu made (if the newly produced golil in any calendar year. Snob gold is either dejiosited at the mints anil assay olhces nf the ruited States, ur exported from the ruited States iu fiiriu of bullion, ores, or coiij)!'!' matte, or used in the in- dustrial arts. If foreign gold bullion enters into any of the above items, its amount must, of course, be deducled. The silver iimdiict of the I'liited States in any given calendar year is estimated in jireeisely the same manner as the gold prod- uct, namely, by making two independent calculations of the same and taking their mean as the actual product.' The \;iriance between these two estimates is confined within narrow limits. The \'ariances for 1902 are as follows: For gold, Cil.Oi'lt ounces, or ii))ouf !.."> per ctMit of either calculation; for sih'cr, (iCi.'.iT^ ouncivs, i. e., somewhtit i)\'er one-tenth of I per cent.

At the Ele\'enth Census the difference was as high as 13 per cent of the refined product. The decline of placer mining and of mining on a small scale generally, the settlement of the mining- districts and the improvement of transportation facili- ties, together witli the progress of statistical methods have all contributed to making the returns of the present census more complete than its predecessors. On the other hand, there can be no coincidence between mine returns and the refined product for the same year, inas- much as a part of the mining product of one year is refined during the following year. The Mint agents in their reports show the distribu- tion of gold between placer and deep mines l)y states and territories. In the following table the reports of Mint agents are compared with the results of the Census: Table -41. — Comparalire statement of the gold contents of tJw jiroituct miiird, us reported to the Bureau of the Census, and hii Mint offieers and (ir/eiits, Inj states and territories: 1!;02.

It is evident by comparison with the Director's estimate of the rctiucd product that the des- ignation "(juartz" includes all deep mines.' The difference between the tw(j sources compared in the preceding statement amounts to G2,iiH7 ounces for placers and 2<)S,()('i,"> ounces for deep mines, in ail 270,932 ounces. It must be borne in mind, however, that tlu^ quantities reported by Mint officers and agents exceed tin; Dir-ector's estimate of the gold product in the contin(>ntal United States by 40,691 oiuices. The excess over the Census retui-ns for placer mines is greatest in Colorado, where the Mint officers repoi-t .31,4-i4 ounces, whereas the Census retui-ns show only 3,172 ounces. It seems probable that Colorado is erro- neously credited by the officers of the Denver mint with the placer bullion produced in adjoining states, but shipped to Denver to be deposited at the United States Mint. The placer product credited to Idaho by the United States Assay Ofiice, at Boise, is 17,-±.5fi ounces in excess of the Census returns; on the other hand, how- ever, the Census returns show an excess of 13, .596 oiuices over the Mint report foi- Oregon; it is very likel_y that the Oregon product found its way through bullion dealers to the Boise assay office. The gold product of placer mines, as reported to the Bureau of the Census directlj^ by producers, was valued at §4, 201:, 995, which corresponds to the value of 2()3,757 fine ounces, as estimated above. In addition to this amount the unreported production of small mines was estimated b}' local men at §1,138,181, which corresponds to the value of 55,386 fine ounces. Most of the placer bullion ultimately finds its way to the mints and assay offices. The report of the Mint officers and agents should therefore be given preference over the esti- mates of other local men. The excess of the amount reported by Mint officers and agents over the aggregate output reported directly by producers to the Bureau of the Census, viz, 123,903 ounces, with a coining value of $2,561,075, represents the product of small mines. The excess of the gold product of deep mines as reported by Mint agents over the Census returns is greatest in Arizona and Nevada, namely, in Arizona, 68,562 ounces, which is equal to 52.5 per cent of the Census returns, and in Nevada 58,386 ounces — i. e., 68 per cent of the Census returns. Th(^ following comparative table ,'«hows the distribu- tion of the silver production by states, as ascei-tained by the census of mines and rjuarries and as estimated by the Director of the Mint. The (juantities reported liy Mint agents are shown in a parallel column. 'Reiinrt nf the Director of the Mint on the Production of the Precious Jlctals, 1901', page 16. 536 MINES AND QUARKIES.

It is therefore difficult to account for the wide diver- gence between the (Census returns and the Mint esti- mat(^ of the gold product of the state. The A'astness of the area to be covei-ed and the sparseness of the popu- lation muv to some (wtent have ati'ected the Census returns; yet, considering that the variance l)etween the Census returns and Mint estimates fcir other states is confined within comparati\-ely iiai'row limits, it seems probable that Nc\a amount repoi'ted to the Bureau of tiie Census from these 'A states —viz, !?1,1:41 —the total value of the, siher i'eco\'ered as a by-product of placer mining aiiKaints to ^ri,57o. The diti'erence between the Census returns and the Mint agents' estinuites amounts to !?4,:-iMS, which does not materially add to the siher jn-oduction or reduce the gold production of the United States.

Where there wa.s a niill at the nihie tlie ii\-erage value of the ore was about ^7 per ton; where there was no mill at the mine the average value \\-as $22. In the al.).seiice of a mill at the mine only ore of a higher grarle was mined. On the other hand, wliere the ore could be reduced at the mine, low-grade ore wa.s ad\'antageously mined and treated. E\en where tljere was a mill at the mine a portion of the ore was shipped to suKdters. The A'tilue of such ore in l'..)(.l2 averaged a) lOut $X>it per ton, whereas the average grade of the ore treated at the mine w as SC, per ton. AVhere there was no mill belonging to the mine the liulk of the ore Wiis sliipijed, the \-ahie of the average grade of shipping ore being si^2^; per ton. In some districts the proximity of custom mills ])erniitte(l the treatment of ores averaging iibout $17 per ton. Another consideration whicli determines the method of handling the ore was the natuic of its nietalli<- con- tents. Ore shipped in crude state frcjiu mines witliout mill connection contained considerable \'aliies in sih'cr. viz, §9,614,-1:4.5, a\'ei';iging ITi ounces per ton. whiTcas ores treated at neighboi'ing custom mills were \iiliied chiefly foi' their gold contents, siKer a\ ei-aging only \> ounces per ton. Lead was also an important eli^ment in -shipping ores, averaging :;.22 per cent of the ore. whereas in milling ores it w;is only a frtiction of 1 per cent. At mines with mill connection the value of the ores tretited was nearly all in their gold contents, silver iUfraging 2 ounces per ton aiul l(>ad only about l.fi2 per cent. The ores sliipped contained a gretiter value in sih'cr than in gohl, the a\-erage tenf)r in silver being 'd-ji ounces per ton. The lead contents were also valua- ble, averaging 12.48 per cent of the crude ore. In such cases the ores were sorted before trciitment; ore rich in silver and lead was shipped to smelters, the rest being treated at the mine. A poi'tion of the ore treated at the mills w;is merely concentrated preparatory to shipping. This was nota- bly the case with ores ricli in lead. The jiroductof the mills contained 2.")'.t,;:!4ti,.sLti pounds of lead, which had to be extracted ))y smelting. The total (juantity of ore concentrated was, accord- ing to i-eports. l.SiiO.fiSi) tons; but much more was proba))ly concentrttted. as the reports on this subject are incomplete. All this ore was concentrated at ])lants btdonging to the mines.

This i-educes tlu' huil< of the ore to l)c shipped to ont>-ninth of its original weight; a largo saving is thus effected in freight and treatment charges. The prices which were j)aid for the metallit' I'ontents of the mining product \-aried in accordance with the condition in which it was marketed, (rold bullion, pro- duced by amalgamating, cyaniding, and chlori nation works connected with mines, sold at $:^0.-l:4 per hne ounce; when the ore was I'educed at custom mills, gold hrought on an average $^0.2ti per ounce. Gold in ore brought from $l!t.^l to $19. it!) per ounce. Silver was figured at 5(> cents per ounce; a portion brought only 4:'.> cents Y>ev ounce. Lead was disposed of at an aver- age of 3 cents per tine poimd; when sold as concentrates it averaged S."2 cents per pound, while in the crude state it brought from five-tenths to 1 cent less. Copper brought from 5 to 8 cents per pound. ('hiirrv cent of the value of tlie gold contents and at 1 cents per oiinci/ (jf siher, which is the highest rate charged by the United States mints and as.say offices. This rate makes a total of §36'.»,216 on gold and $S',t2.751 on silver — in all, S1.2t;i,9'.»7, or, in round ligiires, about $1,200, OHO. This leaves .some- what over $',),(HH),(H)0 for treatment and for freight on concentrates and crude ore. The amount of freight varied for the .several states and within the same state materially, according to the location of the mine. The treatment and freight charges set the limit to the woi'king of ci>rtain grades of ore. Table 15 shows, by states and territories, the total ton- nag(> of ores ti'eated at outside reduction works, the total treatment charges, including freight, and the average per ton, and the highest and lowest freight rate per ton.

About two-tifth.s of all jj-old produced wiis won from low-grade ores worth less than $lo per ton, and ahont the .same share was obtained from ores worth $^1 » or over. Considering- the three principal gold producing states, Colorado, California, and ."-^outli Dakota, and taking p2() per ton as the dividing line between high-grade oi'es and average or low-grade ores, it appears that in Colo- I'ldo high-grade ores predominate, whereas in California and South Dakota the product was chiefly won from low-grade ores. In South Dakota practically all gold was derived from ores worth less than -SIO per ton. Of the smaller gold producers, Utah also treated mostly low-grade ores. Silver was likewise won mostiv from ores avei'aging less than §i!i) per ton, but the lowest grade of ore, aver- aging less than ^li( per ton, was not as conspicuous as in gold mining. A comparati\'e ■study of Ttibles 45 and 4ri will show the extent to which the distance of the mine from reduction works aticcts the grade of ore treated. In Arizona tlie highest cost of freight for shipping ore was $.50 per ton. Very little gold, lio\ve\'er, was produced fi'om ores which could bear such a fi'eight rate. In California the highest fi-eight rate on shipjjing ores was >^36 jier ton, wliile two-tliirds of all gold was ', North Carolina, ()regon, Scnith Carolina, \'irginia, Washington, and W\T)tning. \v Mexico.

In South Dakota the highest freight rate on shipping nrv was S15 pfi- ton, but tlie bulk of the ore was worth less than $ln per ton. and the i|uantitv of high-grade ore, which could bear the liighest freight rate, was insignilicant. An examination of the average treatment charges, inclusi\-e of freight, will show w hat portion of the gold and siher ores produced in each state must be treated at or near the mine and \\hat poi'tion can t)e shipped to distant wdrks. Taking the Tnited States as a wdiole, it appears that two-Hfths of all gold and one-fourth of all siher arc rec(i\cri'il from ores woi-tli li>ss than !?!(> per Ion, \\ liicli could hardly betir the a\-ei'age transpor- tation charges of S7.:!!i per ton and can tlierefore be economically treated oidy at or neiir the mine. On the othi'i- hand, iibout two-rtfths of all gokl and silver are won fr(jm ores worth o\ei' $:iUperton, which could be profitably shipped to distant works for treatment. 4"he following comparativ'e table shows the axcrage grades of gold and siJvei' (U-e minerl in issiiand l\H)i>.

As appears from Tahle 47, in all states and terri- tories, except Oregon, the grade of ore lias consid- eralily decreased, while at the same time the quantity of ore mined and the total gold and silver values show everywhere a remarkable increase. This fact famishes unmistakable evidence of the progress of gold and silver mining since the Tenth Census. The development of transportation facilities and improvement of mining methods and reduction proce.sses have enabled the mine operators to handle large masses of low-grado ore which could not have been profitably mined two decades ago. (Jlayxificatijiii of iiihirx hi/ iiietdls ^iriidiirrd. — In Table 48 all deep mines are classified into two groups— (1) gold and silver mines and (2) argentiferous lead mines. The ore mined from the former is valued chietly for its gold contents, though it carries consideraiile values in silver and .small quantities of other metals. The mines of the latter clas.s yield lead ores rich in silver and associated with gold and other metals. The total gold contents of the ores of both classes were valued at $.57,829,. 542. of which $5,734,t;77. or about one-tenth, was carried by argentiferous lead ores and arolina, '^ennesscc, Texas, \'irginia, Washington, Wyoming, Maine, New Hamp- ined by taking the a\erage between the prices fnr 1X79 and IXXO, which is 81.134. $52.01)4,S(;5 by gold and silver ores. The latter can again be di\'ided into two poi'tions; aliout one-half, valued at S2(i,si(,s,,sf(), carried considerable values in silver, the rest, valued at §25,13*).1(»0, was produced from mines which reported no \ alue for silver. It is probable that in many casi's this gold was likewise associated with si her. liut the percentage of silver saved was too small to lie of commercial value. The silverdead mines include also those which reported no values other than thos(> for silver. The total prod- uct of such mines was \'aliied at $430,281. It is prolia- ble, however, that some of this silver was associated with lead, but the percentage of the hitter was below the 5 per cent limit paid for liy the smelters. The -N'alue of the product shown in Ta))le 48 is onlv that of the ore actually sold or treated. Ore mined but not sold or treated is not taken into consideration for the following reason: (iold and silver ores are mostly reduced at mills connected with the mines. It will lie rememliered that in such cases the value of the increase or decrease of the stock of ore was not esti- mated. Argentiferous lead ores, on the conti'arv, are 542 MINES AND QUARRIES. all shipped to omclters, so that the value of the increase or decrease of the stock was oftener estimated for this class of ore than for gold and silver ores.

As a sur\'ival of archaic methods of production these mines well deserve notice. The 28 mines at which the ore was treated in such manner were distributed among the following states: California, 19; Oregon, 8; and ^Maryland, 1. The total output of these mines aggre- gated $-1:8,280, averaging $^1,724 per mine. There were 36 owners working in the mines, onl_y H of which were operated with hired labor. The average quantity thus treated was less than 9 tons per mine, but the average value per ton was i>2U0. There was evidently no regu- lar produt'tion, but in every ctise a rich strike had been found by men oj small means, who had no other facili- ties for treating their ore.

The time iiMjperiition was re[)orted by 45 custom mills; the diita furnished by them are in- cluded in 4'ablcs 17, is, and 2(1. Of this number, 12 ran more than three hundred days during the year itiid 7 from two hundred tind se\'cnty-onc to three hundred days; these 19 mills may be taken as representing all thiit \vere ill continuous operation throughout the year, except on holidays and when sttjppages were n(>cessary for repairs, etc. Of the other 2(i mills, operated only part of the year, 11 ran from ninety-one to two hundred and seventy days and 15, ninety da3's or less; that is, only during th(> busiest season. The majority, when working, ran more than one shift, viz: 25 i-an two shifts and 7 three shifts, while 13 ran only one shift. When two or three shifts were run the mill was openited uninterruptedly during tw^enty-four hours, making either twelve or eight hours per shift, except in 2 mills, where two shifts of eight hours each were run. Of the 13 mills running only one shift 7 were working twehe hours per day, 5 ten hours, and 1 eight hours. On the whole, tweh'e hours per siiift was the working time in 3U mills, ten hours in 5 mills, and eight hours in 1(» mills. The total capticity of all custom mills per twenty-four hours w;is 2,.sit2 tons. Two mills wdiich treated during the year 350 tons failed to report their dailj' capacity. The total tonnage treated by all mills reporting their capacity was 533,380 tons. It retfuired accordingly 1S4 days of twentT-four hours to handle that quiuititv of ore. This tact shows that the mines provided a suf- Hcient supply of ore to keep the custom mills in con- tinuous operation every day in the year with one working shift of tweh-e hours per day. includini;- Sun- days and holidays. The total value at mill in Tal.ile 53 is S^S, 700.05'.). In computing the total value of the product shown in Table 35 for all mines and njills in the United States, the value of purchiised materials was deducted in order to prevent duplications. The mills handled practically only gold ore of a high grade, a\'eraging !?24 per ton. About two- thirds of the ore treated at custom mills was purchased by them, and only about one-third was treated for cus- tomers at a stipulated rate per ton, the product l)eing retiu-ned to the customers. Some custom work was occasionally done at mills coimected with mines; it was only as an exception, however, that ore was pur- chased at such mills.

In computing the average value per ton it was therefore necessary to add this value in the total value of bullion contents mined and treated; the amount thus added being about 3 per cent of the true value, the error in the average can not exceed 15 cents per ton, which is immaterial, cents being disregarded in the averages.

The a\-erage grade of ore treated by cyaniding at the mine was worth $5 per ton; the average grade; of ore treated at custom mills was higher, somewhat over |.y. which i,s quite natural, as the ore had to bear the addi- tional expen,se of tran.sportation. The value of the ore treated at the mine wdiere cyaniding was the only proc- ess, or combined with amalgamation, averaged $4 per ton; where it was combined with chlorination it was found possible to treat ore worth on the a\ (.'rage about $3 per ton. In some cases the ore was sorted, ores of a liigher grade or rich in silver being sliipped, while low-grade ores were treated at the cyaniding plants.

The ciuantity of such ore treated is seldom figured as a separate item in mine accounts, and was reported to the Bureau of the Census in only a- few cases. Still there were 27 custom mills operating principally on old dumps and tailings. A summarj" of the same is presented in the table below. Of these, 1(1 were cyaniding, 4 amalgamating, and 7 concentrating plants. At the last named the ore was merely concen- trated and then shipped to other works for treatment. The plants were not large, employing on an average about one person on a salary and about four wage- earners. The ore and tailings treated by C3'aniding averaged a little over 13 per ton.

The decline of placer mining in continental United States is apparent from the preceding table. While making an allowance for the incompleteness of the present Census returns for placer mines, it must be remembered that those of the Tenth Census were much more defective. About one-half of the total placer product came from Alaska. Of all other states and territories. New Mexico alone has developed .some placer mining since the Tenth Census. Metlwch of loorhing . — The methods of working in use in placer mines were reported as follows: Hj'draulick- ing, 469 mines; sluicing, 349; drifting, 112; dredging, 44; electric elevator, 1.

About two-thirds of all mines worked l»y hydraulick- ing — viz, 307 out of 469 — reported their average yield per cubic yard of gravel treated. The arithmetical mean of 260 answers for active producers was 34 cents per cubic yard, and the mean for 47 mines under development was 33 cents. The average returns are much higher than those reported at the Tenth Census, when in many mines the product was not above 10 cents per yard, and in some favorably situated workings a considerably lower rate of production was found prolit- able.' Apparently the debris legislation regulating the ' Tenth Census, Vol. XIII, KeiKjrt on I'rccicjus Metals, jjage 200. erection of dams for the protection of navigable waters and farming lands has added to the expense of hydraulic mining, and so permits of the working of a higher class of gravel only. This accounts for the decline of hydraulic mining, which is evidenced by the following comparative statement: Summary for hydraulic mines: 1902 and 1870.

Placer wines comhined unth titamp 'mills. — Placer deposits are sometimes found in ancient river beds covered with a lava cap, in which case the cemented gravel is treated b}' crushing and amalgamation in stamp mills. Eight mines of this character were reported by the present census — 7 in California and 1 in Georgia. A summary for the same follows next below: Table 61. — Summary for placer miiies equipjped with stamp mills: 1902.

The total product of gold dredged for the year 1902 was valued at $1,329,039, of which $846,421 was produced in California, $278,617 in jMontana, $81,823 in Idaho, and $122,178 in Georgia and New Mexico. In 1901 the product of dredging in California was estimated at $471,762 and in 1900 at $200,000.° Of the 44 mines operated hy dredging, 8 were engaged mainly in developing, comjiaratively little gold being- produced by them. These 8 mines comprised 4 in Idaho, 3 in California, and 1 in Georgia. The 36 pro- ductive mines were distributed as follows: Seventeen in California, 9 in Idaho, .5 in Montana, 3 in Georgia, and 2 in Now Mexico. There were 34 incorporated and 10 unincorporated companies. The incorpoi'ated companies were dis- tributed bJ^states as follows: Eighteen in California, 8 in Idaho, 5 in Montana, 2 in New Mexico, and 1 in Georgia. Of the 34 incorporated companies, 7 were reported in the development stage, and of the remaining 27 only .5 paid '' Report of the Director of the Mint on the Production of the Precious Metals, 1901, page 91. GOLD AND SILVER. 549 dividends in 1902, namely, 4 in California and 1 in New Mexico. The total dividends paid by these 5 companies amounted to $246,810, of which |4,760 was paid on $68,000 of preferred stock, averaging 7 per cent, and 1242,050 on $1,104,000 of common stock issued, averag- ing 21.9 per cent. In addition to that, 1 company paid the sum of 17,680 as interest at the rate of 6 per cent on its outstanding bonds amounting to $128,000. There was no gold dredging mine with a product of $250,000 or more. Classified by value of production reported, the 44 mines reported ranked as follows: Four with a product exceeding $100,000, antl with a total of $582,598; 8 ranging between $50,000 and $100,000, with a total of $483,215; 10 ranging between $10,000 and $50,000, with a total of $199,754; 15 ranging be- tween $1,000 and $10,000, with a total product of $59,275; 5 ranging between $600 and $1,000, and 2 pro- ducing less than $500, with a total product of $4,197. It appears from the preceding figures that four-fifths of the entire output was contributed by 12 companies, producing each between $50,000 and $250,000. A summary for gold mines operated by dredges and the capitalization of all incori^orated gold dredging companies are presented in the two tables following: Table 63.— SUMMARY FOR GOLD MINES OPERATED BY DREDGES: 1902.

The area actually treated during the year 1902, in so far as reported, aggregated only 214 acres, from which gold to the amount of 11,243,364 was produced. Fifteen companies, with a total product of $185,675, failed to report the total acreage treated. The average yield per acre, for mines reporting, was $5,870. Twenty-six mines, with an ag- gregate output of $978,508, reported their average yield per cubic yard of gravel treated. The arithmetical mean of their average returns was $0.26 per cubic yard. In computing the mean yield the cubic volume of ground treated was not considered, as it could seldom be accu- rately ascertained; yet the average yield reported, being the result of numerous tests made, is thought to deserve attention. TENDENCY TOWARD CONCENTKATIOX. Gold and silver mining is no exception to the general trend of modern industry toward production on a large scale. This is illustrated by the following live tables, which present a classitication of all mines and mills by value of production. Table 64 comprises all mines and all mills combined with mines, showing separately placers, deep mines without mills, and deep mines with mills. Table 65 deals with custom mills only. Table 66 presents a similar classification of all mines and mills by states and territories. Table 67 presents the same classi- fication for gold and silver and for argentiferous lead mines, and Table 68 presents the same classification for incorporated mines, dividend paying and nondividend paying mines Vjcing shown separately. Onl^- productive mines are dealt with in the last table; mines designated as ''developing and producing"' — that is, those at which expenditures were in excess of receipts — are eliminated from the comparison. In order to avoid disclosing the idcntitj' of individual concerns it has been necessary- in Tables 65, 66, and 6S to combine certain groups shown separateh' in Tables 64 and 67.

The statistics of the production of the mines are col- lected annuall}^ by Mint officers and agents from mine operators. The statistics of the production of refineries are collected by the Bureau of the Mint. The former, as a rule, show an excess over the latter, varying from 1 per cent to 11.4 per cent for gold and from one-tenth of 1 per cent to 11.3 per cent for silver. In 1890, how- ever, the estimate of the Director of the Mint exceeded the total gold product reported by Mint agents by 2.9 pel- cent. The estimated production of silver refineries exceeded the product of the mines in 1891 by five-tenths of 1 per cent, in ]S93 by 13.2 per cent, and in 1896 by 8.. 5 per cent. The estimated production of refined silver is equal to the total silver production of domestic refin- eries less the silver contents of foreign ores reduced in the United States. The fluctuations in imports of silver must inevitably affect the estimate of the refined prod- uct, thus creating a disproportion between the latter and the production of the mines in the United States for the same 3'ear. The excess appearing from year to j'ear in the pro- duction reported by mine operators, as compared with the product of refineries, is easily accounted for by the fact that the former is largely an estimate of the assay contents of all ore mined, regardless of the quantity of ore which will eventually be left on the dump after sorting, as being of too low a grade to pa}' for freight and reduction; nor are the losses in smelting always considered by the mine operator in estimating the assay contents of his ore. The following table shows the gold and silver product of mines and refineries from 1889 to 1902, compiled from the annual reports of the Director of the Mint on the production of the precious metals: Table 69.— PRODUCT OF MINES AND REFINERIES; 1889 TO 1902. 1902 1901 1900 1899 1898 1897 1896 1895 1894 1893 1892 1891 1890 1889 Product of mines.

REVIEW OF THE INDUSTRY BY STATES. The development of the production of gold and silver in the several states and territories from 1889 to 1902 is illustrated by Diagrams I, II, III, and IV. Diagram I, based upon the estimates of the Director of the Mint, shows the growth of the gold production in the princi- pal states and territories and the rank of each as a gold producer; the wide variance between the Mint estimates of the gold output by states and territories and the corresponding Census returns precludes the use of the latter for comparative purposes. The fluctuations of the silver production in the principal states during the same period are represented by Diagram II, prepared from the same source, except for the year 1902, for which Table -10 of the present report was used.

Colorado held in 1902 the first rank among- the states and territories as a producer of both gold and silver. The Colorado ores contributed more than one-third of the gold and more than one-fourth of the silver con- tents of all ores mined in the United States. The second place among the gold producing states was held b}^ California, which contributed over one-fifth of the gold product of the United States. Next after Califor- nia came Alaska, with one-ninth of the total gold prod- uct and with more than one-half of the placer gold produced in the United States. South Dakota, Mon- tana, Utah, Arizona, Oregon, Nevada, and Idaho fol- lowed in successive order.. All other states and terri- tories each produced less than $1,000,000 in gold. The second rank as a silver producing state was held by Montana, Avhich furnished nearlj" one-fourth of the silver contents of all ores. Nearly three-fourths of the silver was derived as a bj'-product of the smelting of copper ores, viz, 9,675,613 fine ounces out of a total of 13, -141, 950 ounces. Utah followed closely, with over one-fifth of the total output of silver. Idaho and Nevada came next. All other states and territories each produced less than $1,000,000 in silver. Silver, as previously stated, was mostly recovered from argentiferous lead ores, Avhere lead formed a val- uable portion of the product. The first rank as a pro- ducer of argentiferous lead ores was held b}^ Idaho. The combined silver and lead contents of all ores mined in that state were valued at $10,291,491:. Utah followed next, with a total value of $8,261,095, and Colorado held the third rank, with $7,296,925. The production of argentiferous lead ores in other states was insignifi- cant. The Colorado ores were the richest in silver, only one-fourth of the value of their bullion contents representing lead. The value of the bullion contents of Utah argentiferous lead ores was nearljr two-thirds in silver and a little over one-third in lead. In Idaho, on the contrary, the ores were poor in silver, more than two-thirds of the value of their metallic contents being lead and less than one-third silver. Taking the lead values alone, Idaho contributed $7,122,838; Utah, $2,873,740; Colorado, $1,827,993; and all other states $486,671. These values do not correspond to the quantities of lead, inasmuch as the price realized in Idaho averaged 3.4 cents per pound of fine lead contents, whereas in Utah it averaged 2.7 cents and in Colorado 2.25 cents per pound. The lead contents of Idaho ores were more than one-half of the total for all argentiferous lead ores mined in the United States. Utah contributed a little over one-fourth and Colorado about one-fifth. A shifting of the relative positions held by the sev- eral states and territories as gold producers has taken place since the Eleventh Census. In 1889 California held the first rank; its product, as estimated by the Director of the Mint, was nearly four times as large as that of Colorado. While its production shows a small increase from 3'car to year, yet it did not keep pace with the rapidly increasing production of Coloi'ado, which in 1897 took the first rank and has retained it since. Alaska, which in 1889 was among the minor producers, in 1902 reached the third place, next to California. No change has taken place in the relative positions of the three principal silver producing states, viz, Col- orado, Montana, and Utah. But while the silver pro- duction of Colorado and Montana, after a period of increase up to 1895, shows a considerable decline, the silver production of Utah has substantiallj^ increased since 1889. Nevada and Idaho, which in 1889 occupied respectively the fourth and the fifth rank, have changed places, Idaho having kept up a steadj' increase. From 1889 to 1899 the silver production of Nevada sank into insignificance. Since 1900, however, there has been an increase, and in 1902 the silver production of Ne- vada was almost as great as in 1889. The variance previous!}' referred to between the Census returns and Mint estimates for Arizona, Nevada, and Idaho accounts for the apparent decrease in 1902 of the gold produc- tion of Arizona and Nevada and for the increase of the silver production of Idaho. It is interesting to note the relative places of the two precious metals in the principal gold and silver produc- ing states in 1902. In Colorado a verj' notable change has taken place since the Eleventh Census. In 1889 the value of gold amounted to $3,883,859, and the coining value of silver to $23,757,751, which was equivalent — at the commercial rate of 93.5 cents per fine ounce' — to $17,5(M»,000 in round numbers. In 1902 the value of the gold contents of Colorado ores was $26,414,800, while the commercial A^alue of their silver contents was $7,740,227, which corresponded to a coining value of $19,617,392. Thus while the decrease of the commer- cial value of the silver product was nearlj' $10,000,000, the loss was made up by the increase in the value of the gold product, and there was a surplus of about $13,000,000 in the aggregate commercial value of both metals. The increase in the value of the gold and sil- ver contents of the Colorado oi'es since 1889 amounted to 60 per cent. In California and South Dakota the production of sil- ver was insignificant, while in Montana and Utah the silver contents of the ores largely exceeded in value their gold contents. Almlrt. — The census of mines and quarries in 1902 did not extend to Alaska. Still, correspondence with the mining companies operating in the territorj' has brought replies covering all essential inquiries relating to deep mining for precious metals in the territory. There were in operation during the year 1902, 7 deep 'Report of the Director of the Mint on the Production of the Precious Metalg, 1902, page 312. 556 MINES AND QUARRIES. gold and silver mines, all equipped with mills for the treatment of ores.

The bullion contents of gold and silver ore produced in 1902, as shown in the preceding table, were as fol- lows: Gold, 126, 327 fine ounces, valued at $2,609,14.3; silver, 7,828 ounces, valued at $.3,638. In addition to these quantities three copper mining companies reported to the Bureau of the Census the assay contents of their copper ore as follows: Gold, 370 fine ounces, worth $7,016; .silver. 3,110 fine ounces, worth $1,.567. This makes in all 126,697 fine ounces of gold, valued at $2,616,1.59, and 10,968 ounces of silver, valued at $5,205. The Mint agents estimated the product of Alaska deep mines as follows: Gold, 124,156 fine ounces; silver, 89,388 fine ounces. The Census returns from producers exceed the Mint agents' estimate of the gold product by 2,511 ounces. The Mint agents' estimate of the silver product of deep mines is many times in excess of the Census returns from producers. Inasmuch as no allowance is made in the silver estimate for the silver contents of placer bullion, which on a gold product of about $2,500,000 must be considerable, it is apparent that the estimate is meant to comprise the silver contents both of ore and of placer bullion. The product of placer mines is esti- mated b\' the Mint agents at 276,551 fine ounces. The total product of Alaska in 1902, as estimated by the Director of the Mint, is somewhat above that of the Mint agents, viz: Gold, 103,7.30 fine ounces, worth $8,345,800; silver, 92,000 fine ounces, worth $118,950. This estimate is accepted bj^ the Bureau of the Census. The growth of the gold production of Alaska since 1890 is shown in the following table, compiled from the annual reports of the Director of the Mint on the pro- duction of the precious metals. The statistics for some years include silver; the percentage of silver in Alaska ores is, however, .so insignificant that the error may be disregarded.

The share of placer mines in the total production for 1898 to 1902 amounted to 67.4 per cent. The history of deep mining in Alaska is practically a record of the work of three companies, the Alaska Treadwell, the Alaska-Mexican, and the Alaska United gold mining companies, which are controlled liv the same interests and operated under a joint management. The annual statements of these companies to their stock- holders set forth in minutest detail the accounts of their operations and furnish an instructive example of the successful mining of low-grade ores.

The Alaska Treadwell Gold Mining Company is the oldest of the three companies. It is incorporated with a capital stock of 15,000,000, divided into 200,000 shares of $25 each, all issued. The mine has been in active operation since August, 1885, and 3nelded during that time 113,484,311 in gold, at an average of |2.57 per ton; the operating costs for the same period averaged $1.29 per ton. The operating protits aggregated $6,74:2,11:9.58, and have thus more than repaid the en- tire capital stock at its par value. The yield per ton has been declining, but the operating costs have also been materially I'educed, while the tonnage crushed has more than trebled since 1890. As a result, the com- pany's operating profits for the year 1902 were con- siderably larger than in years past when the yield per ton was higher. The progress in the methods of treat- ing the ore is evidenced b}^ the fact that while the yield in free gold has been steadily decreasing, the value saved by reworking the ore after the free gold is extracted shows a marked increase both in amount and in proportion to the total recovery. The results accom- plished by the company are shown in the following statement: Bullion shipments from Paris or Tread/well mine: 1890 to 1902.

The total yield per ton for the same year was $2.11, of which $1.04 was free gold and $1.07 was saved in sulphurets. The average value of sulphurets per ton after concentration was $52.58. The net profit for the year was $692,208.94, out of which $375,000 were paid in dividends during the year. The amount written ofl:' for depreciation was $448,493. During the 3'ear there was an average of 33 machine drills at work in the mine. The average number of drills used in mining the ore (stoping) was 14.5. The others were used in development and other kinds of work. The average work of one machine per shift of ten hours was 38 tons. The Alaska-Mexican Gold Mining Company is incor- porated with a capital stock of $1,000,000, divided into 200,000 shares of $5 each, of which $900,000 are outstand- ing. The mine has been in active operation since 1894, and has yielded during that time $2,816,279 in gold, at an average of $2.18 per ton. The operating cost averaged for the same period $1.73 per ton. The operating profits aggregated $587,912, out of which $465,381 were paid in dividends. What has been said above of the Alaska Treadwell Mining Company in regard to the grade of ore and the values recovered in sulphurets is likewise true of the Alaska-Mexican mine, as shown bj' the following^ statement; Bullion shipments from Alaska- Ifexican mine: 189.!^ to 1902.

The Ala.ska United Gold Mining Company is tlie youngest of the three companies. It began operations on the Ready Bullion claim in Novemher, 1.S9S, and on the Seven Hundred Foot claim in April of the follow- ing year. The total yield of the former from begin- ning of operations to December 15, 1902, aggregated $1,5.39,480, averaging $2.03 per ton. Tlie operating cost averaged 11.72 per ton and the operating profits 31 cents per ton. The Seven Hundred Foot claim produced from the beginning of operations to December 15, 1902, $665 ,376 in gold and ba.se ores, averaging $1,59 per ton; the op- erating cost averaged $1.56 per ton, lea\'iiig a profit of 3 cents per ton. The company was capitalized at $1,000,000, divided into 200,000 shares of $5 each, of which $901,000 are outstanding. The total operating profits since organization amounted to $250,191. There was a deficit for the year on the Ready Bullion claim amounting to 2 cents per ton, but the construction ac- count on the same mine, charged to current expenses, likewise averaged 2 cents per ton. Californid. — California had more operators than any other state, viz, more than one-third of the total num- lier reported for the United States. Eliminating from the latter total the l:-47 argentiferous lead mines and considering onh" gold and silver mines, California had about two-fifths of the total number of operators re- ported for the United States. This does not include .small operators from whom no individual reports were received; the latter were also located chiefly in Califor- nia. Of the total estimated value of the product of small mines, 7t» per cent, viz, $1,130,158, was reported from California. It is therefore a fair estimate that there were in 1902 more operators of gold mines in California than in all other states and territories, Alaska not being included in the comparison. The majority of mine operators in California were interested in placer mines; measured l:)y their output, however, the placer mines of California were of minor importance in comparison with the deep mines of the state. Small operators employing no hired latjor were still very numerous in 1902 among the owners of placer mines. Reports were received from 316 mines oper- ated without hired labor; each mine was worked on the average by two owners; the average value of product per mine was $921. Two-thirds of the product of this class of operators was obtained from placer mines. Where deep mines were worked without hired labor, only high-grade ore, averaging $25 per ton, was treated. Most of the deep mines were equipped with mills for the treatment of their ores. Those which had no facil- ities for the treatment of theii- ores were \ery small, employing an average of about two men throughout the year; their annual production averaged only about $3,000 per mine. They treated only high-grade ore, averaging $21 per ton. Those mines which were pro- vided with milling facilities were able to treat ores aver- aging $5 per ton; their annual production averaged $13,720 Y>&v mine. There were among the operators 31 incorporated companies by which dividends were declared in 1902, aggregating $1,099,399, and averaging 4 per cent on the total outstanding capital stock. The ore treated bv these companies was of a low grade, averaging onlv a little over $7 per ton. Their total production for 1902 was valued at $4,866,812. or an av(>rage of $156,994 per mine. The tendenc}' toward concentration of production was pronounced. Thirty-two of the operators, each with an output of $100,000 or over, produced more than one- DIAGRAM I\r-PRODUCTION OF SILVER: 1889 TO I902.

Only the largest mines had their own reduction works; their number was less than one-tenth of the total number of mines in the state, while their product amounted to over two-fifths of the total for the state. The average grade of ore treated at mills connected with mines was A^alued at $9 per ton, whereas the ore shipped from mines without mills of their own was worth $20 per ton. About one-half of the mines without mill connections expended more during 1902 than the value of their product. The average value of their ore was the same as in other mines of the same class, viz, |120 per ton; the treatment charges and freight averaged with them $7.16 per ton, and with others $6.42 per ton. Apparently there was no difference, either in the grade of their ore or in their location, which would place them at a dis- advantage as comi^ared with other mines. It is there- fore fair to assume that the surplus expenditure was invested in development work. 560 MINES AND QUARRIES. The leasing S3'stem is a prominent feature in Colorado. The total amount of royalties for mine and mineral lands reported by operators whose mines were located exclusively on leased land was $379,521, and the aggre- gate value of their product at the mines was $2,190,840. Thus the average rate of royalties was 17. .3 per cent. The average production per mine in 1902 was valued at 111.3.52. This numljer of lessees does not comprise the class of small operators locally known as "leasers," ''block lessees," etc., and designated in this report as "share workers." Two-thirds of the total number of such operators in the United States, viz, Sll out of 1,230, were reported from Colorado. The total amount realized by them, after deducting royalties, was $1,106,602, making an average of ^1,3.59 per "lease." A concise descrip- tion of the system of mining on shares was furnished by Mr. Kenneth McKenzie, vice-president and general manager of the Acacia Gold Mining Company, Cripple Creek, Teller county, Colo., in a communication dated Majr 19, 1903, in reply to an inquiry from the Bureau of the Census. "There are generally from 2 to 6 men interested in a lease; some of them work out for wages and divide up their wages with their partners working on the leased ground until the^^ find ore enough to pay expenses, which verj- often they never do. Man}^ of the men would be working for half wages and an inter- est in the lease. All properties that are operated by lessees in the Cripple Creek district are worked much the same as ours." There were 17 incorporated companies which declared dividends in 1902. The total amount of dividends paid by them was ^3,689,411:, averaging .5.2 per cent on the par value of an outstanding capital stock of f70, 7.53, 173. The total value of their product was 1^13, 801, -±13 — i. e., nearly one-half of the total product of the gold and silver mines of the state; the average per mine was |i293,647. The ore mined by them was of a high grade, averaging $20 per ton. The tendency toward concentration was quite pro- nounced in Colorado. Sixty-four mines each produc- ing -¥100,000 or more contributed over four-fifths (80.1 per cent) of the output of the state; 279 operators each producing less than §1,000 contributed only three-tenths of 1 per cent; and 429 with a product ranging from $1,000 to $100,000 produced less than one-fiftli.

The number of owners working was 92, and the average number of wage-earners em- ployed was 199. The total value of the product was $302,175, an average of $2,379 per mine. One-half of the deep mines were equipped with mills. These were the larger mines, the production of which averaged over $100,000 per mine. The ore treated was of a low grade, averaging about $9 per ton. The mines without mills were of the small tj'pe, with an annual product averaging less than $10,000 per mine. The ore treated by them was of a very high grade, averaging $60 per ton. There were 10 incorporated companies which paid dividends in 1902. The total amount of dividends paid was $880,271, which was equal to 7.9 per cent on an out- standing capital stock of $11,130,420. The ore treated hy these companies was of an average value of $11 per ton. The average production per mine was $358,175. (/oncentration of ownership has made greater prog- ress in Idaho than in other states. Five-eighths, $5,123,859, of the total output was contributed by 6 operators, each having an output valued at more than 30223—04 36 $500,000; one-fifth, $1,648,164, was contriFiuted l)y 6 operators, each with an output valued at from $100,000 to $500,0()(). Very small operators, producing less than $1,000, including those from whom no individual re- ports wore received, contributed only 1.4 percent.

The famous Comstock lode in the early daj'S of it.s history furnished more than one-half of the total silver production of the United States. The flood- ing of the lower levels of the Comstock lode in 1886 reduced silver mining in Nevada to insignificant propor- tions at a time when the price of silver was nearly twice as high as in 1902. The technical progress of recent years, however, has made it possible to resume mining on the submerged levels even with the present low price of silver. The bulk of the product mined in Nevada in 1902 was high-grade ore carrying gold and silver, and averag- ing $62 per ton; this ore was shipped in crude state. There were 16 mines provided with reduction plants where low-grade ore was treated. There were 6 incorporated companies which declared dividends in 1902. The total dividends paid by them amounted to $77,602, which was equal to an average of 2.8 per cent on an outstanding capital stock with a par value of $2,748,000. The average production per mine for these companies was a little over $250,000; the ore treated by them was of a very high grade, averaging $73 per ton. The working of the deeper mines in Nevada required a large investment of capital; hence the necessity of producing on a large scale. Three-fifths of the total yield for 1902 was produced by .5 operators, each with an output valued at $100,000 or over; the production of 1 of these 5 mines was worth over $1,000,000. The principal statistical data for Nevada are pre- sented in the following tables. Table 83 is a compara- tive summary for deep mines with and without mills, and Table 84 is a summary for dividend paying mines.

There was a temporary increase in 1888 due to finds of rich ore. In 1900 the production seemed to be on the increase. The total production has been valued by some as high as 1500,000,000. This lode has produced nearly as much gold as silver. The statement below, drawn from the same source as the one preceding, shows the financial results of forty years' mining operations in the Comstock lode.' All the mines are arranged in three groups: (1) Those whose investments as represented b}^ assessments were repaid by dividends. (2) Those whose dividends failed to repay assessments. (3) Those which paid no dividends. 1 Report of Director of the Mint on the Production of the Precious Metals, 1900, page 159. Forty years' assessments and dividends of Comstock mines.

That so much capital was found for investment in obviously unprofitable ventures is thus explained by Mr. Doten: "The regular a.ssessments levied upon the nonpaying mines were paid with the utmost facility by the market itself, delinquent assessments being imme- diatelj^ added to the price of the .stock, fortune-blinded dealers hardly knowing or caring how it was done or who paid it, and it is to this recklessness of stock speculations that manj' of their mines owe their very existence to-day." avorld's productiox of gold and silver in 1902. Table 85 represents the world's production of refined gold and silver in 1902, as estimated by the Director of the Mint. It shows that as a producer of gold the United States held the second rank, being preceded by Australasia; South Africa followed next, the fourth rank was held by Russia, and the fifth ])y Canada. Great Britain with her colonial empire produced, in round numbers, $151,000,000, or more than one-half of the total output of the world, and the United States followed next with $80,000,000, or more than one-fourth; both nations together contributed four-fifths of the product of the gold mines of the world. Mexico was the leading silver producing country, the output of her mines exceeding one-third of the world's production; the United States followed close behind, with one-third of the world's output. North America contributed 71.9 per cent of the world's production, and Central and South Amei-ica 14.1 per cent, making for the entire American continent six-sevenths of the .silver product of the world. 564 MINES AND QUARRIES.

The United States smelts and refines all silver exported from Mexico and Canada and a portion of the produc- tion of Central and South America. Great Britain, Germany, and Belg-ium tog-ether import about one- half as much silver ore as the United States. The countries from which they draw their supply of ore are chiefly Australia and South America. GOLD AND SILVER. 565 Table 8G.— WORLD'S PRODUCTION OF HILVER FROM MINES AND SMELTERS: IKK9 To 1901.

Lead contents of ores smelted in the United States, 189Jf. to 1902. — A considerable part of the value of the total output of silver mines is the value of the lead con- tents of their ores. \\\ many cases the value of the lead contained deterniine.s whether or not an ore can be mined with profit; and, therefore, statistics of lead are of direct interest in connection with silver. About three-fourths of the entire output of refined lead in the United States is obtained from silver bearing ores, as appears from the following table. The ores of Missouri, Kansas, Wisconsin, Illinois, Iowa, Virginia, and Kentucky are nonargentiferous; all others are argentiferous. { GOLD AND SILVER. 567 Table 87.— LEAD CONTENTS OF ORES SMELTED BY THE WORKS IN THE UNITED STATES, BY STATES AND TERRITORIES: 1894 TO ],902.

Spain, German}', Mexico, and Australia, respec- tively, rank next as producers, while Great llritain, Germany, and France follow in this order as con- sumers. More than one-half of the world's lead output is consumed in the lead producing countries, less than one-half being an article of international commerce. The largest producer for the world's market is Spain, which furnished in 1902 about one-half of the supplj'; next after Spain follows Mexico, and the third place is occupied bj' Australia. These three countries together furnish the supplj' for about nine-tenths of the inter- national demand for lead. The largest consumer of imported lead is Great Britain, which in 1902 consumed more than one-half of the international supply. The second place is held by France. The two countries together have imported within late years from two- thirds to three-fourths of the entire quantity sold in the world's market. The United States produces lead for home consumption only, and imports a comparatively small proportion for the same purpose; but a consider- able quantity of lead ores and base bullion is imported from Mexico and British America, refined in bond, and reexported. The following table shows, bj' j'ears, the share of the United States in the lead exports of Mexico and British America. The first column represents the excess of the product of Mexico and British America over their consumption, as shown in the preceding table, the quan- tities being reduced from metric to short tons. The second column represents the production of refined lead in the United States from foreign ores and base bullion, less the imports of ore and base bullion from other countries than the two above named; both quantities are taken from the estimates of the United States Geological Survey.

The greatest deptli reached after more than twenty years of operation was 3,300 feet. In 1886 work in the lower levels had to be abandoned because of the overpowering flow of water.

The initial cylinder is 64 inches in diameter, with 6 foot 9 inch stroke, and the low-pressure cylinder is 100 inches in diameter, with 8 foot 6 inch stroke. The flywheel is 36. feet in diameter and weighs 208,700 pounds. The wrought-iron walking beam is 22 feet long and weighs 238,610 pounds. The pump rod is 18 by 18 inch Oregon pine, 2,618 feet in length, and its total weight in motion was 1,620,500 pounds; capacity about 750 gallons per minute to a height of 1,180 feet. This pump was started in 1880 and did good work, but was very expensive in its operation. The wdiole plant complete cost over $1,000,000. The Yellow Jacket mine, Gold Hill, had a double line of 14-inch pumps with 10-foot stroke, driven by a horizontal compound engine with double box castings, 64 feet long for the bedplate. The initial cylinder was 31 inches in diameter, with 12-foot stroke, and the low pressure 62 inches in diameter, with 12-foot stroke. The pump rod was 3,055 feet long and weighs, when in motion, 1,510,400 pounds. Its greatest capacity was raising 750 gallons of water 1, 516 feet per minute. The pumps of the combination shaft of the Choliar-Noroross- Savage mining companies, 3,200 feet deep, consisted of a 14-inch Cornish pump and a hydraulic pumping plant, the first on the Comstock. This was operated by waterpower furnished by the Virginia and Gold Hill Water Company and discharged into the Sutro Tunnel. About the time deepest mining was discontinued and the mines allowed to fill and become permanently submerged, which was in October, 1886, this hydraulic system was lifting 2,138 gallons per minute a distance of 1,620 feet to the tunnel level. The total cost of this pumping arrangement was over $1,000,000. At the date mentioned that hydraulic pump had all the water it could possibly handle. The Hale and Norcross 3,200-foot level had come to a connection with the combination shaft, also the Savage and the Chollar, was drifting south from the shaft on the same level. But the Chollar, drifting toward the already sul> merged mines of Gold Hill, encountered a constant increase of water — more than the hydraulic pump could manage. The water gained upon the shaftmen, and the result was that as no increase of pump power was feasible all had to submit to the inevitable and allow the hot water to have full submerging sway henceforth. Recent improvements in electrical engineering and reduction processes have led to the resumption of min- ing on the levels which had been submerged for many years. Saj's Mr. Colcord: The ponderous and powerful hoisting and pumping steam machinery plants of the chief mining companies, originally costing 5)500,000, $750,000, or more apiece, have become dismantled, and electric, up-to-date machinery of greater power and efficiency is being substituted and installed in their place at comparatively a mere trifle of their original cost. For instance, the electric-hoist plant of the Union Consolidated mine cost only about $10,000; Yellow Jacket and Belcher, $12,000 each; and that at the C and C shaft of the Consolidated California and Virginia, the most productive mine of the lode, $16,000. The cost of power furnished, as per con- tract with the Truckee Kiver General Electric Company, is $7 per horsepower, based upon a continuous service and a two-minute peak load. In cases of such continuous service this shows an actual saving of 66 per cent. That is, the former rate for steam power was never less than $21 per horsepower. Technical progress has been facilitated by modern methods of business organization. The pumping asso- ciation formed for the purpose of pumping the water from the mines of the Leadville basin may be cited by way of illustration. This association includes nearly all the leasing companies, as well as the owners of territory embraced in the Leadville basin. All mines operating within the association territory bear the cost of pumping in proportion to their output, based on net smelter re- turns less cost of hauling. By means of counters on these piurnjjs the amount pumped is computed in gallons and cliarged to the as.so- ciation at the rate of 10 cents per 1,000 gallons. Those mines which pump are credited with the amount of water they have raised. Taking the entire district, investigation shows that the flow of water which must be handled is not less than 15,000,000 gallons a day. Comparing this amount of water with the average daily ton- nage of the district for the past year, we find that 28.6 tons of water are raised for every ton of ore raised. Careful estimates of the cost of pumping have been compiled and show that it costs 4 cents to pump each ton of water to the surface. Hence, the cost of pump- ing referred to the ore makes a charge of $1.14 per ton extracted.' Reduction of ores. — The extraction of the metals from the ore was in the early period not differentiated from mining. The most natural method which sug- gested itself to the human mind for dealing with the gold bearing rock was to reduce it to the same state in which the alluvial gold deposits were found and to sepa- rate the disseminated particles of gold from the pulver- ized mass bj^ the familiar method of washing. These primitive methods are still practiced in the uplands of Mexico. Mr. Robert Hill, an American engineer, who examined some of the auriferous deposits in the state of Sonora, thus relates his observations in a village some 60 miles distant from a railroad station: From the adjacent hills the quartz ore was brought in sacks on burros. This was placed upon a flat stone and pulverized with large round bowlders by small boys, this being apparently the first progenitor of the modern stamp mill. The pulverized material was then placed in a primitive arrastra, ground for thirty days by a perambulating burro, and amalgamated. This industry, so the urbane proprietor informed me, had been carried on by himself and ancestors for many generations, and from the ruins of the arrastras in the neighborhood and local tradition there is little doubt that gold has been mined here in a primitive fashion since the first invasion of Sonora by the Spaniards, in 1530, and probably prior to that time by the people who previously inhabited it. From this place onward we found the country inhabitetl entirely by the peasant class, whose only means of livelihood was to proceed to the hills when in need and procure a little gold with which to purchase the commodities of life.^ -Amalgamation was the most imiwrtant discovery inherited by the American miner from his predecessors. Survivals of the most primitive methods of reduction were recorded by the jDresent census of mines and quarries. In a few cases the ore was crushed in ordi- nary mortars. At one mine in Mar3dand the ore, after being crushed in a mortar, was smelted in the neighbor- ing blacksmith shop. A type of mill generally used in the West in the early days of cjuartz mining was the Mexican arrastra. As late as 1880 arrastras .still outnumbered the stamp mills. ^ The arrastra in its simplest form consists of a circular bed of rock from 6 to 10 feet in diameter, with walls of vertical planks, having ' Report of the Director of the Mint on the Production of the Precious Metals, 1900, page 118. * The Engineering and Mining Journal, June 25, 1902. 'Tenth Census, Vol. XIII, Report on Precious Metals pages 282, 283. 576 MINES AND QUARRIES. an upright pivoted post in tiie center, from which extend 2 or 4 horizontal arms. Stone drags, weighing usually from 200 to 1,000 pounds each, are attached by ropes or chains to the extremities of the arms, and are slowly drawn around by the rotation of the latter. The depth is usually between 18 and 30 inches. The pavement and drags are of the hardest rock conveniently obtainable. * * * One man per shift can take care of two arrastras. Some waterpower arrastras working on tailings are so arranged that the only attend- ance needed is in feeding and discharging them, so that practically the labor required is less than the constant work of one man. Con- tinuous arrastras receive no attention other than that demanded tor repairs. The smaller arrastras are worked by a single mule or horse. When waterpower is obtainable, a small overshot hurdy- gurdy, or turbine wheel, is employed.' The capacitj' of an arrastra does not exceed 4 tons per day of twenty-four hours, and usualh^ varies from 1 to 2 tons. A crude arrastra operated by mule power can l)e built for $150, which places it within the means of miners with but small capital. The owner often does all the work. Wooden stamp mills of a very crude type were also known to the Spanish-American miners. A quaint specimen of a homemade stamp mill, fairly represent- ative of its Spanish prototype, was seen at work a few years ago in Georgia. The mine and the mill were worked a few months in the year b_v the owner, with the aid of his aged mother. The son packed selected ore in a bag on his bark to a rude mill a quarter of a mile from the shafts and emptied it into a nail keg. The mother fed the mill with a shingle. Working thus from sunrise to sunset they eked out a living, never making less than $1 a day apiece. The stamp mill has been accepted by all who have seen it as the lirst of its kind. A lO-fout overshot water wheel, with axis elongated at one side, set in propped posts, con- stitutes the motor. Three spindles, roughly hewn, are shod with radially arranged and overlapping liands of iron ( pieces of a wheel tire) bound by a ring. These are the stamps. The mortar con- sists of the remnant of the shoe material. Flat iron plugs, bent at the end, are so arranged in the axia that when it revolves these plugs catch, lift, and drop each notched spindle at different inter- vals. The screen of the mortar chamber is a piece of iron stove- pipe rolled out and punctured with nail holes. A comljination sluice box does the rest. - This mill was imitated b}' other miners in the same and neighboring counties. The cost of construction of a iirst-class mill of this type did not exceed $1(>(). From the wooden mill, by gradual improxement, the present iron stamp mill, with steel shoes and mortars, was developed. The modern stamp milling process is described as follows: Gold stamp milling is that [larticular jirocess in which a heavy cylindrical body is made to fall upon the ore in such a manner as to crush it, and therehiy facilitate a separation between the gold and the valueless minerals by winch the gold is incased. The latter weigh less than the former, and are removed Ijy the aid of water. The gold is then collected through the agency of mercurj-, with which it readily forms an alloy or amalgam. From this combination it is finally extracted by the distillation or retorting of the mercury. The mechanism of the stamp acts on principles similar to tho.se underlying the crudest devices used by njan. It may be likened to a hammer, of which the shoe is the liamnjer 'Tenth Census, Vol. XTIJ, Kcport on Precious Metals, pages 282, 283. 'A Prcliiiiinary Report. Ml a Part of I lie (If, Id I)(. posits of (icort;ia, pages fjs, til). head, the stamp stem is the handle, and the die is the anvil. Thi ore itself has been compared to a nut struck by a hammer, \vhos( blow has separated the valueless shell (the quartz) from the val uable kernel (the gold'). Water covers the die and the ore lyinj upon it. The blow of the falling stamp not only crushes the ore but also causes a violent pulsation of the w^ater. That pulsatioi becomes converted into an irregular splash against the sides of th. mortar. The latter has an opening in front, through which th( water is discharged, carrying with it the crushed ore. This called the "pulp," spreads itself over tables placed on an incline which are lined with a metal, usually copper, having an amalga mated surface, such as will arrest the particles of gold and at th( same time permit the grains of quartz and other valueless materia to pass over it and out of the mill.' With the further progress of gold mining a point wa.' reached where the stamp mill was found inadequate. After the gold bearing veins had been worked to a cer tain depth, usually a few hundred feet below the sur face, the gold would cease to be "free milling" and, because of the lack of those changes which are due tc the penetration of water from the surface, would be come ''refractory," that is, locked up in union witt iron pyrite and other materials, so that it would nol amalgamate with quicksilver.* Man}' mines wen abandoned when the free milling ores gave out. Ir Gilpin county, Colo., this condition was met with ver} early in its mining history, at levels varying from 10( to 200 feet. The mills which had previously been extracting from 60 pei cent to 70 per cent of the gold contents gradually commenced ti: return only 50 per cent, 40 per cent, and then 30 jier cent. Nont but the richest ore would now pay; the mills swallowed up two- thirds of the yield which should have rewarded the miner's toil some of the mines were forced to shut down, while others had t( confine their development to the narrower, richer portions of tht lodes. * * * ^\t this juncture a .small smelting establishment was erected in the district, and the metallurgist came to the rescue of the baflieil niillman.'' The problem was not fully solved, however, until the eighties, when the process of concentration was intro- duced. Only rich ores could bear the expense oi siiipment to distant smelters. As a result, low-grade refractory ores which could not be treated by amalga- mation were thrown away. The new process of concen- tration, which reduced the voliune of ore to be shipped and treated, was tantamount to a discovery of new gold mines. An illustration of a modern stamp mill, equipped witli a concentrator, is shown on Plate I\'. The following description of this process is condensed from the report of the Colorado bureau of mines: The system of ore dressing known as concentrutiou is one of the most important of all processes applied to tlie treatment of ores carrying low values in gold, silver, lead, and coppt.)-.

Many i)rocesses were deviled only to lie fcjeeted by experience. The "proc ess man" hecanu^ the o))ject of cheap ridicule even in otiicial publications. It was, liov\-ever, owing to th(> efl'orts of one of the multitude of these "process men" that the cyaniding- process was invented, which gave to the world the wealth of South African gold. At first the new process was met with distrust 1.)y practical mining men, but it.s demon.strated success overcame the doubts of the skeptics. Immense dumps of low-grade ore and tailings which had been accumulating since the beginning of mining oi)erations were taken up and reduced liy the new 2:)rocess. It is estimated by Professor Munroe that in 11M»2 gold to the value of S^,s.()()(l,()()0 was produced liy the I'yanid- ing process in the United States. This represents an addition of 13 per cent to the productivity of deep gold mines. Improvement in the processes of extracting the metals from the ore is a potent factor in the develop- ment of mining. By th(> old amalgamation process not more than 7t> per cent, and usually not more than tin per cent, of the gold contents of the ore was saved. With the aid of modern processes more than HO per cent of the assay contents can be recovered. General {vditsfrioJ condlt'ionn. — The develojjment of the railway system with consetpient reduction in freight rates has greatly stimtdated the growth of gold and sil- ver mining. When mining operations hrst commenced in Arizona, some mines were 3t)(i miles away from the nearest railroad, and machinery and supplies were brought in Ity nuile team.s." Twenty years ago no mine could be worked there which produced ore worth less than itflSD per ton.' In .some mining districts of Colorado, as late as fifteen years ago, before they were reached by railways, all ores were .subject to freight charges, varying from $.50 to $100 per ton. These con- ditions are now largely a thing of the past. To-day, all inip main railway line. This means a .saving of many dollars per ton on iill ores .shipped, besides a saving on coal and other mice supplies. The decrease of the average value 1 Report of the State Bureau of Mines of Colorado, 1,S97, paees 1-4 and Ic'"!- ': Report of the Director of the Mint on the Production of the p, ions Jfetals, 1901, page 72. ■"^Vibid., 1884, page 56. 30223—04 37 "I 'I '■'' l"'r ton has been noted on a preceding page. Ill the lighted' present statistics tlic following (piotation Iroiii a repori piililished twenty years ago on silver mining in ( 'alifoi-iiia is instructive: nrlion of which is low grade, a\eraging from S40 to the grcati ijilill to Ihe ton Sih'ei- oi'es averaging from S4n to iStid to the ton are to-day consiilered exceptionally rich. The (lecliiie in the average grade of ore mined and treated must injf be mistaken for an indication of what the economist.s call " diminishing returns." The dmnp- ing of a portion of the ore after it has been raised f ron] the mine increases the average cost of mining j^er ton of ore treated. Since it has become possible to treat low-grade ores wdiich formerly had to be thrown a'way, the returns have increased in proportion to the expense per ton of ore actually raised, there being no additional cost of mining. Thus production has been cheapened. The combined effect of all these advances in the jjroc- esses of mining and reduction and in transportation has been the reopening of ntany mines which were aban- doned years ago when the supply of the very rich clioice ores had been exhausted. Stiys Mr. Yale, who has for many years been a close student of mining conditions in California: Along the motlier lode the best i^aying mines of to-day, and the deepest, are those which had lain idle for many years, but were intelligently reopened and propjerly ecjuipped with modern macliin- ery. t'ajntalists seem to prefer to reopen a mine which had made a record for bullion output in it.s early history rather than to take the chances on opening and developing an entirely new prospect. 8e\eral of the most productive mine.s at the present day are tlrose wliicli were aljandoned twenty or thirty years ago, at a depth of 400 or .^0^ feet, \\ hen it was thought there was nothing worth seelcing for further ilown. On the reopening of these mines, however, systematic deej) siniiing was carried on, since whicli time they have been much more profitable than during their early career.'^ The introduction of improved mtichinery and reduc- tion methods calls for a large inA'cstment of capital. The etfect of the technical progress has therefore been the gradual displacement of the small operator work- ing his mine without hired labor on the "■gridt-stake" plan, and the concentration of gold and silver mining under the management of large companies. The gen- eral trend toward production on a large scale has already been noted. The movement toward combination, how- ever, has as yet not )-eached the gold and silver mines. Sniall properties ha\'e here and there been combined into hirger ones: still these small aggregations in no wiiy diti'er from ordinary incorporated companies and lack the magnitude which is characteristic of a modern industriid condjination. In the reduction of ores, on tlie other hand, combination has made considerable progress.

By t^HAKLES E. MUXKOE, Ph. D. The returns for 1902 show that during that year there were 109 establishments, in 12 difierent states, using- a cyanide process for the extraction of the precious metals from tailings or ores. Of these establishments, 29 cyanided the ore or tailings without other treatment; 27 crushed the ore previous to cyaniding; 5 concentrated the ore; 20 combined amalgamation for coarse gold with cj^aniding for the finely divided gold; IS combined concentration and amalgamation with cyaniding; (J com- bined smelting, and in some instances amalgamation with cj^aniding; and 4 combined chlorination, with and without amalgamation, with cyaniding. During the census year these establishments treated 3,089,673 tons of ore and 199,689 tons of old tailings, or 3,289,362 tons in all, and produced 776,050 fine ounces of gold, valued at $15,972,268, and l,7l:l,51r6 fine ounces of sil- ver, valued at $871,878; the products included also 15,000 pounds of copper, valued at $1,670; 711,000 pounds of lead, valued at $12,194; and 8,726 pounds of mercurv (recovered from tailings), valued at $5,620, so that the total value of all the products was $16,863,930. The returns showed directly that of the total oiitiiut of precious metals 289,305 ounces of gold, valued at $5,91:7,888, and 560,872 ounces of silver, valued at $287,611, were extracted from 1,156,613 tons of ore and tailings bj^ means of some cyanide process of re- covery. It is estimated that in those operations in which amalgamation, chlorination, smelting, or several of these processes were combined with a cyanide proc- ess, gold to the value of $2,000,000 and silver to the value of more than $300,000 were recovered by cyanide processes. Hence, by the use of such processes there were produced in the United States, in 1902, gold with an estimated value of about $8,(M.)0,O00, and silver with an estimated value of about $60(),r is determined Ijy the assorting action of the runinng water that transported the materials fi-om their point of origin; the coarser i)articles, recjuiring rapid cur- rents to transport them, are dropped first, while the finer particles arc carried long distances, sometimes scores of miles. Another agent which has ))orne no inconsiderable ])art in this transportation, delivering its burden to the streams at its l;)ase, is the glacier. MINIX(; AND UEI'OVEKY OF OOLH. Phicers.--\n the earlier operations in auriferous dis- tricts, the gold is obtained from the phu'ers by tlie use of the pan, rocker bumper, "long tom," and sluice, and h\ hj^draulicking. The hydraulic process was emphiyed h\ the Romans, but it has probably reached its greatest development in this country, since its intrcxluction in California in ls.33. In this process, as in the workings of nature, the enerjjv of a head of water dislodo-es th(> gold bearing detritus, and the buoying power of water at different rates of flow separates the heavier from the lighter particles. E\'en in ancient times, these methods were often supplemented by the use of mi>rcurv, eitiier in the liquid state or exposed on plates, to I'atcli and retain, by amalgamating with them, the lightei- parti- cles of gold, which «(.)uld otherwise flow awav «ith the dirt. More recently, di'edging has been )-esoi-ted tcj in order to recover the gold beai'ing alluviiiin fi'om ri\er beds, and even from deposits in former ri\er beds, ()\-ei' which ha\-e since formed deposits of silt so deep that the water has been turned from its course. Five iiiiUiiKj Dfrx. — When the placers lia\'e been ex- hausted, attention is given to the riM-(i\'er\- of the gold 111 Ki.tu by \ein or (|uai'tz mining. As long as the ore is free milling, the process consists in detarliing it from the vein by dialling and blasting. It is then <-i-ushi'd by stamps, crushers, or rock breakers, and treated, like placer deposits, by sedimentation and amalyaniation. The machinery and de\ices used fiu' coneenlration, separation, and aujalgamation have been \er\- liiolilv developed, especially during the past centurN . Dui'ing the last half ciMitury treatment In cliloi'ine has been resortefl to f(]r the reco\-er\' of the line gold. Ri'j-nichii'ij (iri'K — (ilil iiiitliniU. - \\'lien ref ractor\- ores are reaehed. Ilie methods of mining are ehanged. lie- fore the intl'oduction ol' Ihe cyanidi' |)idce,ss, the i^dld in these (jres was extracted l)\- smelt int;', ehlorinalion. or (jther elaborate chemical process, the degree of suc- cess depending on tlie richness of the ore in precious metals or in other materials that would yield a profit on the operations. Thus the precious metals associated with galena were alloyed with the lead reduced from it by smidting, and subsequently reco\ered by processes such as that of Parkes cjr ]''attison; iron pyrites carry- ing the [irecions metals were roasted to convert their sulphur content into sulpliuric acid, and the precious metals were then recovered from the pyrite cinder, and these methods are still employed. Copper pyrites, which usually carries gold and silver, and has long been a source from which these metals were obtained, has become a notable source of supply, since the develop- ment of ]\Ianke's method of bessemerizing copper mattes and the successful relining of this impure copper by (dectricity. These are a few among numerous methods proposetl or usihI for the treatment of refractory ores. Ill the de\idopment of the milling processi^s it has I become possilile to assort the ore into different concen- 1 trates, each of whiili is treated Ijy tliat process which will most ertectively and economically extract the gold and other valuable substances present. On account of th(> cost of transportation or treat- ment. liowe\-er. at many mines r — were disposed of as iiiexpensividy as possible. Thus, in the early days of tlieComstock lode m Nevada, which has yielded gold and sihci- valueil at more than Ss-fO. (too. nun.' the treatment of the ores was limited to mill batti'ries, amalgamating pans, and settlers, the tailings — still con- taining notable (|uantities of the jirecious metals — lieing deposited in the canyons leading to the Carson river. Later, blanket sluices, ritfh's. and othiM' devices were enqiloyed to catch the rieli snlphurc'ts that had escaped prex'ioiis treatment, as w(dl as (|uicksil\-er and amalgam from the plates; in addition, restraining dams and reser\i)irs were constructed at fa\'orable points in the two i-anyoiis. and along the edges of the ri\"er. to catch the lailine-s and the rich chloride slums or st'ttlino-s, but both the dams and their accumulations were some- times swept aw ay by winter floods. Since the ert'ction, in recent years, of several cyanide plants at Sih-er City and Six Mile Canyon to work these tiiilings, it has lieen estimated, on the basis of the values n'co\-ered from the tonnage work, that the value of the precious metals swept into the river and spread o\er its erratic bed and sandy Hats aggregated !?(;(>,()(»0, 'j'his estimate is sup]iorted by the results obtained in att(>mpting to reco\ei' some of these values from the river bed by niillino- oi'cs, soiiii'- tiiiies the finest particles of j;-old were not preei])itiited l)y the ritHe hars or eauo-ht on the ))lankets, hut floated away with the slimes; ayain, the <;'rains of yold were often "rusty," or so coated as to refus(> to amalnaniatc^ ■when hrou^-ht in t'ontact with the mercury, and hence, in spite of the use of metaliie sodium, or of potassium cyanide and other chemicals, much j^old eseapiKl; or the presence of lead, copper, ar^enic, antimony, or otlier substances in the ore I'aused the mercury to become "foul," and therc^fore luiable to take up gold. These, ct>ml)ined with other causes of loss, have led to the esti- mate that althouuh gold to a value of over-?l,( »()(). (>00,(I(.HJ has been produced in California since iN-iS, "yet more has been wasted in milling and hydraulic mining by being washed down the rivers and even to the ocean." Such were the conditions that existed in 1888, when, liy tests made on a large scale, it was demonstrated that the cyanide process for the recovery of gold and silver from low-grade ores was of practical value and low cost, uiaking it possible to work profitably the large bodies of low-grade ore scattered over tlie earth, and the enormous piles of tailings accumulated around both abandoned arid active mines and mills and being con- tinualh' added to as mining and milling proceeded. THE CYAXIDK PKOCESS. Hlstonj. — According to Hoefer,' )3i-ussic acid appears to have been known to the P^gvptian priests, who used it for poisoning initiates guilty of divulging the sacred mysteries. According to Prissier,'' the fact that gold when in a line state of division was soluble in cyanide of potassium was already known in the Middle Ages, when the gilding of metals was carried out by jewelers and alchemists by the use of gold in cyanide solutions. Un- less potassium cyaiude was at that time made from prussic acid obtained from vegetable sources, it is diffi- cult to reconcile this with the statements made by Watts, by Roscoe and Schorlemmer, and other authorities, that potassium ferrocyanide was discovered by Macquer in 17.52 and hydrogen cyanide by Scheele in 1782; foi- these, particularly the former, are the present sources of potas- sium cyanide. It has long been known, however, that in the kei'nels of the bitter almond, peach, apricot, plum, cherry, and quince, in the blossoms of the peach, sloe, and mountain ash, in the lea\es of the peach, cherry laurel, and Portugal laurel, in the young branches of the peach, in the stem bark of tlie Portugal laurel and mountain ash, and in the roots of the moun- tain ash, there occur certain glucosides which, through the action of an enzj^me in the presence of water, be- come hydrolyzed, yielding hydrogen cyanide, or prus- sic acid, as one of the products.

Lehner has recently shown ' that gold will dis- solve in common acids, like sulphuric and phosphoric, if oxygen be present in the sohition, and that the solu- bility of gold in selenic and telluric acids is due to the fact that at the temperature which obtains in the reac- tion these acids are themselves broken up into dioxides and oxygen. The first instance of an attempt to a])ply thi.s solvent action of the cyanides to the extraction of precious metals from their ores or other bodies containing them appears in United States Patents tilS6t> and (52776, issued to Dr. Julio H. Rae, of Syrat'use, N. Y., on February 5 and March V2. 1S67. Dr. Rae claimed the use not only of potassium cyanide as a solvent for the precious metals in the ore, but also of an electric cur- rent in precipitating them from tlie sohition, and of rotatory or movable electrodes. This was followed by United States Patent 229586, of July <;, Is.so, to Thomas C. Clark, of Oakland, Cal.. who roasted his ore to a red heat, and placed it, in this coTidition, in a cold bath containing salt, prussiate of potash, and caustic soda; United States Patent 236424, of January 11, ISSl, to H. W. Faucett, of St. Louis, Mo., who subjected hot crushed ores, under pressure, to the action of •sodium C3'anide in solution; and United States Patent 244080, of July 12, 1881, to John F. Sanders, of Ogden, Utah, who treated his ore with potassium cyanide and glacial phosphoric acid. But in each of these last three patents the object was to cleanse the gold pi'e\-ious to amalgamation, potassiiun cyanide having l)een used for a considerable time, in California and Australia, for removing the coatings from rusty gold in the pan amalgamation process. In 1884 Astley P. Price applied for British Patent 5125, for the use of zinc in a state of Hue division in precipitating gold or sih-ei- from solutions containing them. On July 28, 1885, United States Patent 323222 was issued to Jerome W. Simpson, of Newai'k, N. J., covering the extraction of gold, silver, and copper from their ores by means of solutions containing potassium cyanide, ammoniuui carbonate, and sodium chloride, and the sid)se(juent precipitation of the dissolved metals by means of pieces or plat(^s of zinc suspended in the solution. A caveat for tli(.' use of cyanide was hied in the United States Pat<'nt Oflice by F. M. Endlich and N. W. Mhhlenbcrger, rluring tiie sam(.' yeai', but was subsei|ue,ntly abandonerl. At Park City, Utali, about the same time, Louis Janin, jr., made expei'iments ' .Journal of the [lages •5.5(J to .5.5.5. ■ricMii ( liei ■;d Soi-iciv, r.KIt, \'ol. I'd, with cyanide in extracting silver and gold from ores, which led to his tiling a caveat on Ma}' 1, 1886. He did not press this to an issue, but he published his results in th(> Engineering and Mining Jotirnal, 1888.^ W. A. Dixon also made experiments with C3'anide on Australian ores, and recorded his results in a paper read before the Roj'al Society of New South Wales. The cyanide process acquired commercial ^-alue in 18H7, when John S. MacArthur and W. Forrest, of Glasgow, Scotland, applied, on October 19, for their English i^atent covering the use of dilute solutions of cyanides in the extraction of the precious metals. Later they ol)tained a patent for the use of zinc as a precipi- tant in a particular state of subdivision. The commercial value of the cyanide proce.ss was demonstrated by tests made on a large scale, with ore from the New Zealand Crown mine, in June and Jidy, ISSS. Commercial success dates from the introduction of the MacArthur-Forrest process, in 1890, in the Wit- watersrand gold fields in South Africa, the first cyanide plant in the world for treating tailings having been erected at Johannesburg in April, 1890.^ In the Wit- watersrand alone, at the end of Isyi, there were 6 com- panies treating tailings by the cyanide proce.ss; at the end of 1.S92 there were 22; and at the end of 1893 there were 32, with a record of 143,500 tons per month treated. By the use of this ])rocess there were re- covered in the Rand 2S6 ounces of gold in 1890, 34,862 ounces in 1891, 178,688 ounces in 1892, 330,510 ounces in 1893, 714,122 ounces in 1S94. 753,490 ounces in 1.^95, and 7o3,7o4 ounces in 181*6; the output then increased up to September, 1M98, when the commencement of active hostilities in the Boer War interfered with the active working of the mines. 2let]nired ore with a dilute solution of an alkali cyanide, drawing ofi' this solution when charged with the precious metals, and precipitating these metals from the solution. In the patents of INIacArthur and Forrest the claims «ere made for the use of dilute solti- tions of cyanide (not more than S parts of cyanogen to 1,0(10 jiarts of watei'); the employment of caustic alka- ' lies for neutralizing acid ores, pi'ior to their digestion in the t'yanide solution; and the use of zinc, preferably inafiliform condition, as a precipitant. The cyanide first used was potassium cyanide, butcyan-salt, whichisamix- ture of sodium and potassium cyanides, has come into extended use. The tailings, or a charge of ore crushed to the desired fineness, are placed in the leaching vats or taid'is and, if acid, given a preliminar}- treatment with lime or sodium hydroxide, which is generally washed out before further treatment. The ore is then subjected to the action of the cyanide solution, which is usually admitted at the bottom of the leaching vat; after digesting for a length of time, depending on the ■' Page .54S. ■'Alfred .lames, tlyanide I'racticc, fioiitispiece, V.Wl. CYANIDP] PR(JCES8K>S. 597 character of the charge, its linenesw, its freedom frcim slimes, and the strength of the c^yanide sohxtion, the solution containing the precious metals is drawn off and the operation repeated. According to Eisner's equation and the elaltorate investigations of MacLauriii and Christy, the presence of oxygen in the solution is essential, hence many operators use sodium peroxide or other oxidizing agents with their C3^anide solutions. The leaching or percolation vats varj^ nuich in form, dimensions, and construction. Thus they may lie of wood, barrel-shaped, 22.5 feet in diametei- and 4 feet deep, and holding a charge of 30 tons; or of concrete, rectangular, 50 by -10 feet in area and 4- feet deep, and holding 150 tons. The following facts from Packard's paper on "'J'he CVanide Process in the United States"' indicates the wide ranges of variation in methods: In the Mercur district the ore is covered with solu- tion, which is allowed to stand from thirty mimites to six hours and tlien drawn oil'. This operation is repeated from eight to thirty-five times. Here the material leached is so coarse that there is no danger of " paclving." Each operation of covering takes f I'om two to six hours. A few mills cover the pul]) with solution, allow it to stand forty-eight to ninety-six hours, draw it off, and wasli. Many of the mills follow the strong solution with a wasli of weak solution (one-tenth per centor less). This is in turn followed bj' a water wash, which fiows through the zinc boxes into the weak solution tank and becomes the first wash for the next charge. lu the extraction processes referred to above the treatment with cyanide solutions is accomplished by percolation. This method is widely and successfully used, but it has its disadvantages. If the material treated is a clean sand, the solution penetrates througli- out the mass, exerting its full solvent effect, aiul the subsequent draining and washing are easilv accom- plished. But if the ore contains some kind of rock which is converted by the crushing into a powder that when moistened produces slimes — a formation which is most marked when the rock is of a clayey nature — the presence of these ore slimes in the leaching vats may retard or even prevent percolation, according to their amount and character. In working ores of this kind, the difficulty has been obviated by coarse crushing, but in that case gold is lost, because the sol\'ent can not penetrate through the coarser granules of ore to the inclosed grains of metal. To overcome these defects in the process, resort is had — as in the Pelatan-Clerici process, or in the use of the Aurex sluice — to agitation during exposure to the cyanide solution. Eurthermore, since in these processes amalgamation and precipitation are carried on nearly simultaneousl}- with solution, not only is the coarse gold quickly removed, but the rustj' ' Transactions of the American Institute of Mining Engineers, Vol. XXVI, pages 709 to 721. gold is made capalde of amalgamation through being cleanseil by the action of the cyanide and the electric current, which are emplo\'ed simultaneously, while tlie float gold is either' amalgamated directly or dissolved and then precipitated. In these processes the pi'ecious metals are recovered as amalgams, which need only retorting and uudting to lie rendy for the mint. A novel method of o\'ercoming th(; impernuiability of slimes is found in the sugg(;stion of Count von Schwerin, '' who proposes to remo\e water from wet cla}' and similar amorphous fine slinies b}' passing tlirough the mass an electric current, wliereby the water is driven to the cathode and the solid particles to the anode by "electric endosmosis." The apparatus eonsists of a wooden vat having for a bottom a bi'ass netting, which forms the cathode; the water being drawn to the net- ting cpiickly runs off'. In the MacAi'thur-Forrest process, the cyanide solu- tion containing the gold and silver is next run into zinc boxes for the precipitation of the precious metals. The zinc Ixjxes, like the leaching vats, vary in character at the different works. A form in conunon use in the United States is made of 2-inch dressed plank, bolted together and painted with parafiin paint; it is divided into six compartments, I'i ])y 2<( inches in cross section and 20 inches deep, and is provided with a screen about i inches above the bottom, on which to place the zinc shavings. About sixty pounds of shavings are required to till the box. It is provided with an inlet and an out- let pipe, and in the bottom of each compartment is placed a 1-inch pipe closed with a stopcock, through which the slimes are drawn oft' in cleaning up. The circulation in the zinc box is secured by having the first partition of a compartment extend from the top of the box to within 3 inches of the bottom, while the second partition extends from the bottom of the l>ox to within 2 inches of the top. The screen for the zinc shavings is stretched Ijetween. The solution from the entrance pipe falls to the bottom of the box, passes under the first partition, rises up through the zine shavings, flows over the second partition, and thus proceeds up and down from compartment to compartment until it reaches the exit pipe of the box. The ^Mercur mill is equipped with long sheet-iron boxes having wooden partitions wedged into place; these can easily be reujoved for cleaning up, the slinies being all lu-ushed together. At the Cripple Creek mill, the slime discharge pipes of the zinc boxes lead from the side of each compartment and discharge the slime into a trough leading to a. tank. When the potassium cyanide s(.)lution comes into con- tact with the gold in the leaching vat, the gold is dis- solved, forming potassium aurocyanide, according to the following ec^uation: 4 KCy + 2 Au -f + H.,0 = 2 KAuCy^ + 2 KHO.

    os(|ui stated" that at Bodie. Cab, after many dis- couraging failures, the f<.)llowing method of operating in treating the zinc-gold slimes was adcjpted, and has been followed with entii'(> success: Till/ slimes and line zinc arc discharged directly from the Xinc boxes iido a redwood vat li feet in diameter and 2 feet deep. Thi.s vat is protected on the inside by several coats of paraffin paint, has a slight hottouL incline for drainage, and i.s provided with a 2-inch disi-hargc vahc. Here the slinies are treated with sulphuric acid. .U'tcr the destruction of the zinc, the zinc sulphate and the slight I'Xccss of acid present are diluted by filling the vat with warm water. Within an hour the \m\k of the precijiitate will liave settled to the bottom. The supernatant liquor, to the amount of about 4(1(1 gallons, which still contains a small amount of gold slimes in sus])cnsion, is then sijihoned off into a 10-ton .settling vat. The gold slimes are treated with a succession of these washes, Ihe supernatant liiiuor being each time drawn off into the settling \'at, until the amount of zinc snl]iliate remaining in the slimes is insignificant. The lii|Uor siphoned off into the settling vat, whicli I'ontains only a very small i|nantity of shines in proportion to the total i|naiitity obtained, is left to settle between clean-ui>s. The clear li(|iior is drawn off just bcfo)'e a succeeding clean-up, and at long intervals the precipitate is gathered from the bottom and meltc(l. The bulk of the slimes is finally discharged from the acid vat into a liltcr box. This box is provided, about a foot from the top, with a perforate(i partition which is closely covered with two thick- nesses of ordinary mill blanketing. I'^rom the compartment Ije- neatli this filter the air is witliib'awn by nutans of a steam ejectrjr, and the water is thus I'eiiioved from the slimes by suction. At the bottiMii of the l)ox is a 1-inch ilischarge \alve for dra\\ing off the accumulated I'lear liquiil. I'.y occasionally scraping the filter blankets the passage of water through them is greatly facilitated. Tlicse blankets are removed and washeil after each clean-up, anil clean ones are substituted. The ]iartially dried slimes from the blankets are then conipletely dried over a furnace and melted in crncililcs. The zinc residues being thus pretty thoroughly removed from the slimes, the ditticnities in melting are redui-ed to a min- iniimi.

CYANIDE PUUCESSES. 5',tU Precipitants other than filiform zinc are sonictinn's employed to throw down the gold. Thus, at the Delamar mine, Nevada, the precipitation is by zinc dust,' with aofitation: MoUoy preci|)itates with sodium or potassium amalu'ain, Moldenhauer with aluminum, .lohnston with pulverized carbon, Christy with taiprous chloride, iind De Wilde withcupric sulphate. Precipitation is etfected also by electricity, amalgamated copper plates beinjj;- used in the Pelatan-Clerici process, and thin lead plates as cathodes, with iron anodes, in the Siemens-llalske process. Electro-depo.sition processes seem to possess an ad- vantage over ziiK; precipitation processes in that the presence of caustic soda makes no ditt'crence in the re- sult, and that th(\v are as i'ti'ecti\e with a weak as with a strong' solution.

In this connection it may lie noted that in Wag'ner's Chemical Technolog}'^ there is described a method of treating- refractory ores, invented hy W. Crookes, which consi.sts in suijiecting the powdered ore to the action of an alternating' current in the presence of a solution of mercuric cyanide or of some other soluble salt (jf mercur}-. The methods used in the Witwatersi-aTid have been described recently by John Hays Hammond,' as follows; The following description applie.s to the treatment id' ures in the pyritic zones. Ores from the upper (exiilizeil) lidiizniis (d' the reefs, which constitute but a small percentafje nf tlie ures treated, require a slight inoditication of the process. The ground near the mines is level, and dees net |ierinit trans- portation by gravity; consequently the ore niust he llrst elevated into the ore bins at the mill, and the tailings leaving the mill must be elevated for treatment hy the cyanide process. This is done either by tailing pumps or, preferably, hy tailing wheels. These are from 40 to 50 feet in diameter, and discharge the tailings into a launder, which, witli a grade of about :15 per cent, carries them to the cyanide works. The auriferous pyrites are, to a large extent, taken out as concentrates by means of fSpitzlutten (hydraulii' ■'Manual of Chemical Technology, K. von Wai'ner, translated bv W.

These com^entrates are taken to tanks for sep- arate treatment. From two to three weeks of treatment is required in order to obtain from this material a recoverv of ii-i,m 90 to 9.5 per cent of thegol.l it c(ditains. A solution of about 0.25 to 0.3 per cent of cyanide cd' i.otassium is used. After passing over (he Spitzlutten the tailings are run to Spitzkasten (pointed boxes), where the heavier sands are allowed to settle, while the lighter material (slimes) overflows, and is carried to the slinje works for special treatment.

This separation id' the sands from the slinu'S has to be rarefull)- niade, so as to remove all clayey sub- stances, the ))resence of w hich would otherwise prevent ra])id pier- colation of the solution and tlie free access of atmiispheric ox'ygen, which is essential to the solution of gold by cyanide, -Most of the modern plants luu'e a system of doidile treatment, the tailings being settled in the .settling tanks, when they are treated, after being allowed to drain, with a weak solution of cyanide of potassium. This addition of the cyanide of pota.ssiuiu is made rather for the jiurpi^se of .saturating the sands with the solution than for thorough leaching, which wmild be difficult on account of the jiacking of the sands as they are settled, rendering liercolation ditlieult. After the solution has been drained off, the .sands from the settling tanks are discharged into the leaching CYANIDE PUOCESSES. 601 tanks, placed immediately Ijelow tlie settling tanks, I'roni wliicli they are tilled from diseharKe doors on the hottom id the latter. For a 200-stamp plant 16 steel settlinfj; and 16 steel leaehini,' tanks are nsnally employed. From 3 to 4 settlin^and leaching tanks are used for the treatment of the Spitzlutten concentrates above ile- scrilied. Tlie settling tanks are usually 40 feet in diameter and S) feet high. The leaching tanks have the same diameter, hut usu- ally a foot less height. The capacity of these tanks is about 4(1(1 tons of ])ulp each. In the leaching tanks the pulp is subjected to three treatments with cyanide of potassium. Where the Mac Arthur-Forrest process is used, the strong solution contains 0.25 per cent, the medi(nn solution 0.2 per cent, and the weak solution 0.10 per cent of KCy. In the Siemens-Halske process the solutions are weaker, namely, the strong solution, 0.10; medium, 0.02; and weak, 0.01 per cent of KCy. The treatment requires from four to seven days. From Kioto 150 tons of solution are usually employed for 100 tons of saml. After being allowed to drain, the sands are discharged tlirongli liottoni discharge doors into trucks, in which they are removed to residues or tailings heaps. Here, again, elevation is necessary, on account of the flatness of the country, and is usually effected by the endless rope system. These tailings heaps are conspicuous throughout the mining district. By reason of the heavy winds prevailing at certain seasons of the year, they are becoming a great nuisance, and the question of their future disposition is one of the problems for the mining engineer. The cyanide solution, after being drawn off from the leaching tanks, is taken to the precipitation boxes. The gold from the strong solution is precipitated in one set and that from the weak solution in another set of boxes. Precipitation is effected 1)y either the MacArthur-Forrest or the Siemens-Halske process. The MacArthur-Forrest process. — In this process the gold is pre- cipitated by zinc, the solution passing upward through a succession of compartments, in which are placed zinc shavings or filings, rest- ing on a movable tray of c character of the process and the apparatus used: in the location of the mill with regard to the supply of ore or tailings used; and the source of powei'. water, materials, and labor. According to H. M. Chance,' in the Black Hills, 8. Dak., the cost of smelting silii/eous ores was between $4.75 and $.5.7^ per ton: the cost of chlorinatiDU. from $3.5it to |4..")(» per ton; and the cost of the cyanide treatment, possibly from fc3 to $3.75 per ton. From the Report of the Director of the Mint, for the calendar year 1901, ■•* it appears that in that year there were 11 cyanide plants in active opei'ation in South Dakota, having a united capacity of over l,5nii tons daily, and that some of these mills claim to be able to treat ore at a cost not exceeding SO cents per ton. though the average cost is probably nearer $1.5<( per ton. Julian and Smart" give 21 difi'erent detailed accounts of costs at mines in Aus- tralia, Africa, and the United States, the results rang- ing from ;^s. 1.23d. per ton l)y the Siemens process, in South Africa, to 17s. 1.02d. per ton l)y the Diehl proc- ess, in ^\'estern Australia.

There are no collected data to afford a comparison of the condition of this industry in that year with the condition during any previous period since its introduction into this coun- try, in 1891. But the consensus of e\-idence, as pre- sented in current literature, indicates that tlie industry has been constantly growing, that new plants are going up each year, and that established ones ar(> increasing tlu'ir capacity. This is true not only of the United States, but also of Africa, Australia, New Zealand, Mexico, and the other gold protlucing coun- tries; from each are coming increased suppHes of tlie ])recious metals extracted from low-grade oi-es and tailings.

DIGEST OF UNITED STATES PATENTS RELATING TO CYANIDE l^ROC^ESSES FOR RECOVERY OF PRECIOUS METALS. THE This digest covera most of the patents inehided in the following classes and subclasses of the United States Patent Otlice classilica- tion : Class 75. — Metallurgy. Subclass 18. — Solutions and Precipitation. Subclass 86. — Solutions and Precipitation — Apparatus. Subclass 185. — Cyanides. Class 204. — Electrolysis. Suljclass 15. — Aqueous Bath, Ores. Some of the patents in these categories are quite foreign to the subject under consideration, and many Ijut indirectly related to it. It has been thought, however, from the form which discussions of patent issues often take, to include the latter. The aim in mak- ing the digest has been to give such a sketch as will indicate the nature of the invention and what is claimed by the inventor, this generally lieing done by an actual abstract from or paraphrase of the words of the letters patent, but no responsibility is assumed for the opinions, theories, or claims thus set forth. Other related patents may have been granted which do not appear in this digest, because they are not embraced in the subclasses enumerated. Thus, the patents number 229586, to Thomas C. Clark; 236424, to H. W. Faucett; and 244080, to John F. Sanders, do not appear in this digest, because the first two are classified under subclass "Re- ducing and Separating — Disintegrating Ores," and the third under subclass " Reducing and Separating — Gold and Silver," and neither of these suliclasses is included in this digest.

Then charge the chlorinating vessel with this sludge and apply the pumps to cause its circulation therein, drawing from the upper part and discharging into the lower part, while chlorine gas is pumped into the vessel, preferably to a pressure considerably above that nf the atmosphere. After circulation has gone on for some time, uutil the metal in the ore is mostly dissolved by the chlorine, the sludge is pumped by the circulating pumps into the filter press, additional pressure being given, if required, by using the chlorine pump to force air into the upper part of the chlorin- ating vessel. The liquid issuing from the filter press containing in solution the metallic chloride is treated in any of the known ways for separating the metal and reco\'ering the chlorine. In some cases the solution discharged from the filter press may be used in a subseciuent operation to form the sludge by its admixture with a fresh quantity of pulverized ore, and this may be done repeatedly, so as to obtain finally a filtered liquor rich in chloride. As it is advantageous to charge the chlorinating vessel with an excess of chlorine above that which enters into combination with the metals, the inventor prefers to collect such excess before dis- charging the sludge by blowing in a little steam to warm the sludge and allowing the free chlorine thus liberated to pass either into a gasometer t>v into another chlorinating vessel; or an exhaust pump may ije employed to draw off the free i-hlorine. When metals such as silver are present, having insoluble chlo- rides, the Ijlocks which are taken from the filter press, and which contain these chlorides, may be reduced to sludge, as before men- tioned, and may lie subjected to the same treatment with a suitable solvent instead of the chlorine. 418138— Ikcernber S4, 188H.

W. D. Bohm. Apparattis for separalimj gold and silver from ore. The inventor places the powdered or divided ore, or material to be treated for the obtainment of the gold or silver, or both, in a vessel (jr vat, or vessels or vats, and through it passes the leaching solution, preferably previously heated. By means of a force pump, the leaching solution is forced up through the ore and through a filter at the top. The solution and the precicjus metal which it now contains pass into a vessel in which it is agitated with a pre- cipitating agent. From this last-named vessel the solution is forced up liy a force pump through a \'essel having a filtering arrange- ment, such as a porous diaphragm, at the top, so that the solid matter is retained thereby, the liquid passing off to be heated again and to be restrengthened Ijy the addition of the necessary further quantity of leaching chemicals and passed back to the leaching vat or vats for reuse. The pressure under which the liquids are forced up through the leaching vat and precipitant vessel should be at least eighteen pounds per square inch. At intervals the solid matter retained by the last-named filtering vessel is passed into a filter pjress or equivalent apparatus, whereby it is deprived of the greater part of its moisture. The ore which has been leached is then drained of all solution and washed free from the last traces thereof with water, preferably hot, and then can be washed out of the \at or vats with acidulated water, and passed over zinc or alloy of zinc with other suitable metal, so that hydrogen is evolved, which reduces any precious metal still remaining in the ore to the metallic state, or such state that it is taken up when the ore is afterwards passed over mercury — for instance, over amalgamated copper. 49.'>38.'j— April 11, 1893.

V. Akgall. Apjpjoratas for e.vtraction of precion.^ metals. The specifications set forth that in the treatment of ores by the cyanide process to e.Ntract their gold and silver contents, it is the usual practice to pjlace the ores in open leaching tanks and allow the cyanide solution to percolate through the mass and so dissolve and remove the precious metals in solution. This method is on the whole fairly efficient, but it occupies considerable time (forty to eighty hours) and causes a large consumption of cyanide through decomposition, owing to its long contact with the ore and atmos- phere. With many classes of ore, however, it is found that agita- tion of the ore and solution is necessary in order to obtain the best results or largest extraction of precious metals. Particularly is this the case with silver-bearing ores or ores carrying considerable value in silver. The agitators heretofore in use shorten the time necessary to dissolve the precious metals; but they invariably cause a large consumption of cyanide, due chiefly to the continuous agitation of the solution in open tanks or in partly filled barrels in the presence of an excess of air, while the ore when discharged from the agita- tors is in such a condition that very often it can not be leached, or at best but part of the cyanide solution containing the dissolved gold can be separated from the ores. Then again, the agitators now in use are of such small capacity as to add largely to the cost of treating the ores. Tliis invention relates to a new machine for treating ores by con- tinuous agitation and continuous percolation unx settlement and idtration. '>::7 144 — SepAembrr S, lS9i:. S. B. Ladd. Apjparatus for leaching ores. The object of the present invention is to provide an economical and practical apparatus for the lixiviation of ores, and particularly applicable to cases where a large mass of material has to undergo treatment — as, for exampile, in the lixiviation of low-grade gold ores by the cyanide process — and where the expense of han(.lling material becomes an important factor with respect to the commer- cial working of the process. The invention applies, generically, to the lixiviation of comminuted or pulverized material of any character, but it is espjecially designed for the lixiviation of ores by the cyanide process, fi ir in the treatment of ore pulp or slimes by the cyanide and other like processes a large amount of material, often of a low grade, has to be subjected to the action of an aque- ous solution of a cyanide or other solvent, or to the successive action of a series of solutions. The common course of procedure in working the cyanide pjrocess on a large scale is to run the ore pulp intci large vats and then to cause the proper solutions for leaching out the precious metals to percolate therethrough, for example, first an alkaline solution, when the ore is acid, then a strong solution, then a weaker solution, and finalh' water to \\ ash the pulp. The vat is then emptied and refilled with fresh ore pulp; also, the solvent process is sometimes worked by agitating the pulp and leaching solution in pans or vessels. Both svstems require considerable labor and are intermittent. Another ol)ject of the present invention is tij provide means to make the extraction process continuous, so that the ore pulp shall progressivel)- and continuously be associated with the solutions or the washings which may be necessary for thoroughly exhausting the values from the ore. This is acccjmplished by constructing a leaching tank, in the form of a long tmugh, which may be divided by one or more fixed or removable bridges into so many trough sections as are required for the several solutions or washings when 618 MINES AND QUARRIES. one leaching is not sufficient; or by providing a series of tanks or troughs operatively arranged with respect to each other, employ^ ing in connection therewith a conveyer for the ore pulp adapted to continuously feed the |iulp with a steady movement through the several solutions in an uninterrupted flow through the appa- ratus to the point of discharge without any intermediate stoppage or handling of the same whereby the lixiviation of the ore is effected. For the purpose of rendering the operation continuous, provision is made for a constant drawing off of the charged solution or solu- tions from the leaching troughs and an inflow of fresh solution thereto. In the case of the first cyanide solution the inflow is preferably at the ore-entrance end of the trough or trough section and the current is with the ore, thus catching the fine float golil carried by the fresh pulp; but in the subsequent troughs or trough sections, and also in the first, if preferred, the inflow of the solu- tion (or washing water) is preferably made at the ore-exit end and the outflow of the solution is at the opposite end where fresh ore ■or pulp is entering the trough or trough section. Thus, in this latter case, the flow of the solution is opposite to that of the ore. The fresh cyanide solution first acts upon pulp which is largely leached out, and as the solution becomes more and more charged with the gold or precious metals it meets pulp that is progressively richer in the metals, and the conditions are therefore favorable for effecting a complete extraction of the precious metals by the solvent. As a preferred form of conveyer, slowly-moving blades transverse to the trough or tank are used. These blades extend across the tank with just enough room at the sides for clearance, and they reach from above the surface of the solution down to and into the ore pulp on the bottom of the tank with openings or notches in or along the lower part of the blades for tlie underfli:)W of the solution. These blades divide the trough or tank into a number of communicating divisions and form what may be called "traveling partitions," moving slowly through the trough from end to end thereof. The lower edges of these blades are prefer- ably fashioned with rake teeth, and they open up and rake along the layer of ore pulp on the Vjottom of the tank and effect a slow and progressive movement of the mass with a constant plowing therethrough and exposure of fresh portions thereof to the action of the solution, while the solution in the tank as the series of blades move forward has to flow back through the notches or openings in the bottom of the traveling blades from each of these divisions formed by the blades, respectively, into the adjacent rear division, and thus there is secured a constant and steady under- flow of the solution in close proximity to the agitated pulfi. This flow of the solution is in addition to and distinct from the flow due to the constant addition of fresh solvent at one end of the trough and the drawing off of the charged solution at the other end thereof; but it will be seen that the underflow thus effected pre- vents a mere surface flow of the solution from one end of the trough to the other. On the contrary, as the flow from the respective divisions of the trough is from the bottom and under each traveling partition or blade, the overflow or discharge from the trough at the end is necessarily of the charged portion of the solution. It will be seen that this method of leaching ores places the ore and the solvent under perfect control, which is a very great advantage with respect to the economical leaching of ores. There is an agitation and constant shifting of the pulp in the solu- tion, which very ninch accelerates the action of the solvent and shortens the time required therefor, and the speed of the conveyer can be regulated sothat the pulp will not reujain in the tank or tanks any longer than is necessary, and yet long enough for the extraction of all value therefrom. On the other hand, the flow of the solvent through a tank can be gauged so that it will i.^sue from the taJik fully chargcil or charged to the degree most profit- able under all the cnndilions (if the case. 576118 — February ,?, 1897.

In order to extract said metals, the sea water or salt lake water is |iasseil tlirough a filter made of carbon, and the gold and silver held in solution in the sea water or salt lake water are freed from the chemical combinations in which they occur in the water. The chlorides and bromides of gold and silver in solution when passing through the carbon filter are decomposed by the reducing power of the carbon, the liberation of chlorine, and the destruction of the bromine combination, with the result that metallic gold and silver are precipitated in the carbon filter and deposited in the pores and ui)on the surface of the carbon.

This invention relates to a method of charging ore or tailings to a leaching vat, which process is a step in the treatment of said ore or tailings preliminary to the application fif the solvent solution in cyanide, hyposulphite, or other hydronietallurgical proces.ses. It consists, essentially, in conveying the tailings or ore by any well-known adaptable mechanical means to a point above the cen- ter of the vat to be charged and delivering the material there to a hopper, wiiich feeds a revolving chute inclined at an angle greater than the natural .slope of the material to be handled, and with openings adjustable both as to size and position, through which the material to be treated falls gently into the vat and distributes evenly, thus giving a charge of minimum density and maximum homogeneity, the conditions most favorable to successful leaching and dissolution of the precious metals. The ordinary method of charging leaching vats is from cars run- ning on a superimposed track. By this means the momentum of the carload of tailings or ore dropping through five or more feet to the bottom of the vat is such as to i)roduce consideraV)le packing, and, moreover, an uneven packing or density. For instance, in dumping from an end discharge car the resultant mass of ore or tailings will take the form of a cone in the vat and the maximum density will be in the center of the approximate circle forming the V.)ase of the cone ami will decrease along the radii toward the cir- cumference of this circle. Furthermore, the variation in fineness of the different i-arloads is not eipialized, and a vat charge of ore or tailings results, which is heterogeneous, both as regards density and as reganls fine and coarse material. Now, first, the charge of ore or tailings in a vat should be of the least density possilile to obtain, because experience has demonstrated that the greater the permeability, and consequently the greater the amount of lixiviant possible to jiercolate through the charge, the greater the extraction of the precious metals in a given time, or, from another standjioint, the greater the permealiility the less the economic period for leaching, and liciice the less the cost for plant and subsequent operaticm; second, the charge should be as nearl> homogeneous as possible as regards both density and size of material, because in leaching ores it is necessary to follow solution with wash water to replace and prevent the loss of tlie former or to follow one lixi- viant with another of different strength or containing a different solvent, and in doing this to maintain the surface of demarcation between the one and the other as nearly a horizontal plane as pos- sible in order to minimize the mixing of efiBuent solutions. The aliove conditions of minimum density and maximum homogeneity are produced by means of a revolving inclined wide chute with small openings in the bottom, adjustable as to size and position transverse to the direction of the .stream of ore or tailings. By means of this method a number of very small .streams of ore or tailings fall gently into the \at as the chute revolves, and by in- creasing the speed of revolution a carload of fine or coarse material can be spread over the whole area of the vat, thus giving the small- est possible dimension parallel with the course of the lixiviant. 6.53631— .Inly 10. 1900. .1.

J. P. Pchuch, Jr. Ore mi.riiig machine. Heretofore, in treating gold bearing ores by the common cyanide process, the ore is first crushed, dried, and rolled to a proper de- gree of fineness, and that which requires roasting is then conveyed to the roasters, while the oxiilized ore wdiich does not require roasting is conveyed to the bin or receptacle therefor. After the portions of the ore to be roasted have passed through this step of the process the same is conveyed to the cooling room before being deposited in the bin or receptacle referred to which contains the ore requiring no roasting. All of the ore is then removed by manual labor into the ordinary stationary cyaniding tanks, ami after these tanks are filled with the ore the cyanide solution is introduced therein. In this process the filled cyanide tanks, with the solution and ore therein, are permitted to remain filled and unmolested for a sufficient length of time for the solution to act on the ore, after which the gold bearing solution is drawn off and allowed to flow to the precipitation room, while the tailings in the tank are then washed with water and shoveled out or sluiced out when this is possible. In this process, which is the one usually followed out in extracting gold and silver from their ores by the use of cyanogen containing solvents, the percentage extracted rarely exceeds 80 per cent of the ore value, and it is the purpose of the present invention to provide means whereby a larger per cent of the value of the ores ma}' be saved. To this end the invention contemplates an improved mixing machine which provides for a thorough aeration of the ore and .solution, while at the same time providing for a mixing of various grades of ore with the cyanide solution, so as to make one even grade out of ores of various values. And the inventor claims, in an ore mixing machine, an open tank provided at the bottom with a -solution drain, a perforated false bottom arranged within the tank above the main bottom and supporting filtering material, an ore discharge jiipe communicating with tiie interior of the tank immediately above the plane of the false bottom, a revoluble agi- tator depending within the tank into close proximity with refer- ence to the false bottom, and a plurality of air jets arranged to communicate with the tank in a plane intermediate the said false bottom and the lower end of the agitator thereabove. 064196— December IS, 1900. 3.

In cyanide treatment the sands are subjected to the action of cy- anide solution, which solution after the proper length of time has elapsed is drawn off through a filter composed of matting or some similar material situated at the bottom of the tank. This matting or filtering material does not rest directly on the bottom of the tank, but is supported by a grating or perforated false bottom in order to allow a free passage for the solution which has filtered through. That portion of the tank, therefore, which is situated o\-er the rlis- charge door has no grating or filtering material, and consequently a more or less vertical column of sand is left in the tank, which still contains cyanide solution with gold in .solution, the result being that this portion is imperfectly treated. The object of this invention is to pro-\-ide a door so constructed that a piece of matting or filtering material may be placed upon it in order that the filtration of the solution shall be just as complete over the discharge door as in the rest of the tank. This invention furthermore relates to an improved construction whereby the door is rendered much more easily closed and also to a system of packing the same by which the joint between the door and the bottom of the tank is rendered tight. 683413 — iSeptemher 24, 1901.

In the precipitation of gold and silver from cyanide and other solutions zinc is usually employed as a precipitant, and the use of iron vessels containing the solutions has l)een found oVjjectional)le, because the iron being electro-negative to zinc a galvanic action is set up between the •s'essel and the zinc, which causes the precious metal to be deposited upon the vessel instead of upon the precipi- tant. Owing to this difficulty the general practice has been to use vessels constructed of wood or earthenware, which are inconven- ient and do not facilitate the cleaning-up operation. The object of this invention is to avoid these objections. To this end the invention consists in a metallurgical filter for separating precious metal from a solution containing it, consisting of a metallic vessel and a zinc sponge disposed therein, said vessel having an inner coating of enamel, whereby galvanic action be- tween the metallic vessel and the zinc is prevented and deposit of precious metal on the vessel avoided. 70.5736— July 39, 1903. ,T.

G. MooRE. Apparatu.^: for leaching ores, etr. In dissohing the soluljle portions of ores, furnace products, and other like materials it has always been difficult in one operation to dissolve the final traces of the soluble portions and at the same time completely utilize the dissolving power of the acid alkali. The weakening of the acid or alkali by its dissolving action makes its action less energetic toward the finish of the operation at the very time when the more difficult soluljle particles needing the most energetic dissolving action are acted upon. This not only causes loss of reagent, but also further loss on account of the poor extraction of the soluble elements desired. Also, in the case of ores of a talcose or slimy nature the talcose portions in the form of slimes prevent percolation of the solutions in tanks by clog- ging. These slimes should be separated and filtered separately by known methods. Then the remaining portion will easily allow percolation. The object of this invention is to provide an improved apparatus for the purpose of overcoming these difficulties; and with this object in view the invention consists, primarily, in a hollow trun- cated cone njounted to rotate about a central horizontal axial line, provided with an opening at one end to receive the material to be acted upon, an opening at the opposite end tertiu'es, a lead launder arranged on the exterior of the barrel ami |iriivided with a plurality of lead braiii'h pipes, said branch pi|ies at ( heir inner ends being fitted in .'Jaid afiertnri'S and rnniieeteil to the leail lining about said perforations. 719273— January 27, 1903.

Three water wheels were reported, representing 22 horsepower. Sixty horsepower was supplied by 5 air compressors. There were also 3 electric motors with 15 horsepower. Production ill till' Uiriti-d Stuten. — The quicksilver produced in the United States during 1902 amounted to 34,291 flasks of 7ij.5 pounds each, aggregating 1,189.9 meti'ic tons, and valued at $1,407,848, as compared with 20,404 flasks, 918.3 metric tons, valued at |1,190,5(M1 in 1S89. This shows an increase in (juantity of 7,827 fla.sks, and in \'alue of $277, 34s. ovei' the statistics at the Eleventh Ceirsus. ^Mercury is transported in cylindi'ical wrought iron flasks, each 5 inches in diameter and about 14 inches long, closed with a screw plug, and having a capacity in the United States of 70.5 pounds. At Aliuaden, Spain, and Idi'ia. Austria, the capacitj' is slightly less, being 70 pounds. Of the 34,291 flasks produced in the United States during 1902, California contributed 28.972 flasks, or 84.5 per cent, and Texas 5,319 flasks, or 15.5 per cent. Except as noted below, the entii'e output of quicksilver in the United States has been derived from California, and statistics of i)roduction and the average value per flask for that state during the period from 1889 to 1902, inclusive, are given in Taljle 3, as reported by the United States Geological Survey. In addition to the output of California, the following quantities have been ))rodiiced in Texas and Oregon: Texas, in 1899, 261 flasks; in 1900, 750 flasks; in 1901, 2,932 flasks; and in 1902, 5,311» flasks; Oregon, in 1900, 233 flasks and in 1901. 75 flasks.

In the latter case a relativelj- low price is obtained for the metal, as it has to compete in foreign markets with the European product. In some cases the prices vary accoi'ding to the rates of transportation from the vari- ous entry ports to the points of consumption, in order to compete with the f^uropean product which may enter at other ports; thus, comparatively higher export prices are obtained at westei-n coast ports of Mexico than at interior points of consumption adjacent to railroads l(>ading to eastern ports. The average monthly price of quicksilver, per flask, during 1'.I02, as reported by the United States Geolog- ical Survey, is given in Table 4. The lower averages during IiH)2 indicate the periods of largest sales for export, iuid the higher averages indicate periods of sales for domestic consumption.

It is a brig-ht tin-white liquid, and, wiien free from impuritie.s, the o-lobules retain a perfectly spher- ical shape. The luster is mirror like, and like that of silver it is preserved in air free of sulphui'ous o-ases. Mercurj', when cooled to a temperature of — 38. S" C., is transformed into a tin-whitt', ductil(\ malleable mass, softer than lead and cr3'stalliziny in octahedrons. Dur- ing the cooling it contracts uniformly until the tempera- ture of solidiKcation is reached, at which point a con- siderable contraction takes place, and, as a consequence, the solidified mercury will sink below the surface of liquid mercury. At 0- C the specific gravity of mer- cury is 13.596 and at — 38. S- C. the specific gravity of solidified mercury is l-i.193. In ver}' thin films the liquid metal is transparent and of a violet-blue color when viewed by transmitted light. The specific heat of solidified mercury (between — 78'^ C. and — 40- C.) is 0.0247; that of liciuid mercury (be- tween 0"^ G. and 100- C.) is 0.0333. Its thermal con- ductivity is 667, compared with that of silver taken at 1,000, and its electrical conductivity at 22.8'^ C. is 1.63, silver at 0- C. being taken at 100. The boiling point of mercury at the standard pressure of 760 mm. is 357.25' C. Al)0ve this temperature it becomes a transparent, colorless vapor, having a density of between 6. 7 and 7.(i3, referred to air as a unit. The densit}^ of gaseous mercury comparctl with hydrogen is 100.92, and as its atomic weight is 19H.8, this element in a gaseous form consists of monatomic molecules. Mercury gives ofi' vapors at all temperatures; This may be illustrated by suspending a piece of gold leaf above the surface of mercury in a stoppered bottle; the gold leaf will slowly assume a white color from the formation of gold amalgam on the surface. In its licjuid and gaseous forms mercury is poison- ous, producing salivation when taken either internallv through the lungs or stomach or by absorption through the pores of the skin. ^Mercury is not tarnished by exposure to the air, nor is it acted on by many gases; hence it is an invaluable aid to the chemist in the col- lection and measui'ementof gases which are sokiltle in or absorb water. "When subjected to prolonged heating in the air, mercury is slowly transformed into red mercuric oxide (HgOj, which at a higher temperature is again decomposed into its elements — mercury and oxygen. Liquid mercury is con\'erted by agitation with oil or by trituration with sugar, chalk, or lard into a (kdl- gra}' powder. This process is called "deadening," and is used to prepare mercurial ointment, the gra}' powder consisting simply of very finely divided mercurv in the form of minute globules.

Sodium and potassiimi amalgams are decomposed l)v contact witli water, yielding hj'drogen gas and an alka- line hytlroxide; for this reason sodiuin amalgam is used in the laboratory as a reducing agent. Zinc amalgam is acU'd upon Aery slowly by dilute sulphuric acid, and on this iiccount the sui'face of zinc plates in galvanic batteries is usually amalgamated. Tin amalgam is used to produce the reflecting surface of ordinary mirrors, and amalgams of gold, copper, and zinc are used in dentisti-y as fillings for teeth.

Vermilion is invaluable as a pigment, because of the permanence of its vivid cochineal-red color. It is made artificiality in two ways — one, termed the dry method, in wliich an intimate mixture of metallic mercury and sulphur in proper proportions is heated in a retort and the suli- limod product condensed and ground very fine, the beauty of the tint depending largely upon the fineness , of the material; and the other, called the wet method, by which various (.'ompounds of mercury are trans- I foi'med into the sulphide l>y the use of chemical reagents. Vermilion prepared by the wet method is of l.ietter qiuility than that made ))v the dry process. The manu- facture of vermilion has declined in recent years on acc'ount of the competition of cheaper pigments which have supplanted its use. The most important of these is ""orange mineral" (red lead), which is toned up to the proper color by the use of eosin, one of the aniline ] dyes. These imitation vermilions are now employed for almost all of the more common uses, such as wagon painting, and while they are inferior to the true mer- cury vermilion, from the fact that they fade on expo- sure, yet they are a fairly satisfactory substitute as long as they are protected by an exterior coating of varnish. Mercury vermilion is now used chiefly for red colors in oil paintings, lithography, etc. The extravt'iov of mercury fro m its (/res. — Mercury is 1 extracted by heating the ore in a retort or a furnace; the metal is expelled as a vapor, which is subsequently i condensed in cooling chambers and collected. Up to the present time mercury has been extracted from its ores solely by the dry process. Various chemical and electrolytic methods have been proposed repeatedly and numerous experiments made, but with- out commercial success. Perhaps the development of electric current gener- ated by waterpower in localities where the use of fuel is nearl}' or quite prohibitive will render profitable the extraction of the metal by some electrolytic process. The principal ore of mercury, as already stated, is cinnabar, mercuric sulphide, accompanied at times with minute globules of native mercury. The metal may be extracted from the ore by a simple distillation, either in a retort or in a shaft furnace, and though n.iercury may be separated from cinnabar in numerous ways. only two methods are now used on a large scale. One is based on the decomposition of the ore at a high temperaturt^ b\' air, forming metallic mercury and sulphur dioxide gas in accordance with the reaction: IlgS-fO,, = Hg+,SO, {'.'m" C). The other accomplishes the decomposition bv the use of lime- or iron which combines with the sulphur and sets free the mercurj- in accordance with the reactions: J:}IgS+-tCaO = -tHg+ 3CaS+C'aS0„ and IIgS+Fe = FeS+Hg, i-espectively. These chemical decompositions take place at tempera- tures al)ove the boiling point of mercury so that the latter is expelled in gaseous form and subsequently con- densed imd collected in cooling chambei's. In present furnace practice tlie heat necessary for the decomposition of the ore, either with or without the admixture of lime or iron, is applied in two ways — first, by heating thi' oxo charge in a tightly sealed ii-on retort, which produces the mercurial \'apor undiluted witli furnace gases; and second, by treatment in a large fur- nace, where the products of combustion come in direct contact with the ore and pass (uit of the furnace in the form of sulphur dioxide gas, nitrogen, and unused air, mixed with th(> expelled mercurial gases, from which the metal is obtained liy condeasation in the cooling chandlers. Thus the essential difference ))etween the two methods is that the vapors given ofi' in the retort furnaces are entirely separate from the furnace gases of combustion. The retort method possesses the advan- tage of yielding the mercurial vapor in a concentrated and easily condensible form, which is more than offset, however, by the high cost of fuel and labor involved and the small hize of a single charge. At jjresent the use of iron retorts is restricted to exceptionally rich ores and mercurial soot and concentrates. The furnaces now generally used in California are of the shaft type, into which the ore is fed continuously. There are two kinds of these furnaces — one called the "'coarse-ore'" furnace, used for treating lump ore, and the other the ""tile" furnace for medium-sized and fine ores. There are many differences in the details of the couhtruction of c(jarse-ore shaft furnaces, but in gen- eral they consist of a cylindrical brick shaft, into which the ore is charged at the top, while the cinders are removed at the liottom. The heat necessary for the reaction is supplied at or near the bottom of the shaft, the gases of coml.)ustion passing through the oi'e col- unui, and, togeth(>r with the liberated mercurial vapors, pass out from the furnace through a pipe at the top and are led to the condensing plant. The general tvpe of tile furnac(> consists of a number (if narrow rectan- gular shafts, each having a series of tiles inclined inward and downward and so placed alternatel}^ on the longer sides that the tine to medium sized ore (up to 3.5 inches in diameter) will follow a zigzag path in its descent, until it is finally discharged at the bottom through the drawing pit. The ore is gradually heated in its descent liy the products of combustion from the (i54 MINES AND QUARRIES. fuel burned in the tirepliices at or near the bottom of the furnaee. The condensing plant generally consists of a cooling device and a condensing chamber in which the liquetied mercury is deposited. The gases passing out from the furnace must necessarily be of a temperatui-e higher than the boiling point of mercur_y (3.57.25'-' C), and the mercury content of these gases b}' volume is often less than 1 per cent. In addition to the products of combus- tion of the fuel and the mercurial vapors, these furnace gases contain sulphur dioxide, which is derived from the decomposition of the ore, which when cooled yields acid liquors that attack ordinary materials of construc- tion. In the construction of the condensing apparatus for the proper cooling and condensation of the mercur}' three factors must be taken into consideration: The dis- tance the gas has to travel, the interior capacity of the chamber, and the area of the cooling surface. The details of adjusting the construction of the condenser to give the best results vary at each plant. The mate- rials used in building the condensers should be nonab- sorbent of mercurial vapor, good conductors of lieat, not affected by acid vapors or liquors, and capable of being molded into the required form. No one sub- stance answers all requirements. Iron is a good con- ductor of heat and may be easih' shaped, but it does not resist the corrosive action of the acid vapoi's, and to overcome this disadvantage the iron pipes are often protected from corrosion by a coating of cement. Brick absorbs mercurial vapors, is attacked b\' acids, and is a bad conductor of heat. Wood will resist acid, but is a bad conductor of heat, and can not be i:)laced near the furnace where the temperature of the gases is high. Glazed stoneware resists the action of acid and mercurj', and may be made thin in order to offset its poor heat- conducting qualities. As with the variations in the selection of the materials of construction used, so is it with the general arrangement of the condensing plant. Uses. — The most important commercial use of mercury is in the extraction of gold and silver from certain ores by the amalgamation process; the precious metals becom- ing alloj-ed with the mercury, form a heavy amalgam, which is separated by gravity from the tine sands and the "tailings" of the ore suspended in water. Owing to the avidit\' with which mercury combines with iiupu- rities, thereby becoming subdivided into innumerable minute globules which will not coalesce, consideral)le quantities of the metal are lost during the amalgamation process, by Iteing held in suspension in the water, and washed away with the sands and the tailings. In the chemical industries large quantities of mercury are used as electrodes in several electrolytic processes, notably in the electrolysis of Ijrine to form sodium salts. The solution of salt having })cen decomposed by the electric current, the metallic sodium thereby set free at the cathode immediately combines with the mercury, from which the sodium is subsequently extracted by a treatment with water, forming sodium hj^lroxide (caustic soda). On account of its high specific gravity, and its freedom from attack by many gases, mercury is an invaluable material for the construction of liquid seals in gas collecting apparatus, for making thermometers and barometers, and for making electrical contacts in certain apparatus used in physical laboratories and industrial processes. REVIEW OF THE QUICKSILVER INDUSTRY IN THE UNITED STATES DURING 1902. The cjuicksilver deposits of commercial importance in California are situated in the Coast Range and are lim- ited to an area bounded b}- Trinity county on the north and San Luis Obispo county on the south, both counties being included. During 1902 San Benito county con- tributed 7,289 flasks, valued at |i30t>,096, the product being derived largely from the New Idria mine. De- velopment work was carried on during the year at the Cerro Benito and the Pichaco mines. In Napa county the chief producer was the Napa Consolidated mine at Oat Hill. In the Knoxville district the Boston mine, formerly the Readington mine, under the control of the Boston Quicksilver Mining Company, and the Manhat- tan mine contributed to the output. The total produc- tion for Napa county during the year amounted to 7.300 flasks. Santa Clara county was next in the order of quantity produced, contributing 5,779 flasks. The chief producer in this county was the New Almaden mine, fol- lowed by the Guadalupe mine. The New Almaden mine is the oldest quicksilver mine in the United States. It was discovered and worked in 1824. when California was under Mexican rule, and was then known as the Chaboya mine. Later it was abandoned until 184-5. and since 1850 it has l)een worked continuously. Furnaces were erected at the Santa Tere.sa and the Summit mines. San Luis Obispo county supplied 2,546 flasks, the chief producer being the Karl Quicksilver Mining Company. A new Scott furnace was installed and put in operation at the Oceanic mine, and development work was actively carried on at a number of smaller properties, notably the Alice, Modoc, Libertad, Madrone, Pine Mountain, and Stayton mines. Lake county furnished 3,797 flasks, olitained chiefly from the Great Western mine. The Sulphur Bank and Abbott mines, controlled by the Empire Consolidated Quicksilver Mining Company, were in litigation during the year. The Helen mine fuinished a small quota, and promising development work was done at the Bullion mine, operated bv the Standard Company-. From Colusa county a consider- able product was obtained from the Manzanite mine. Sulphur creek, where a successful process of ore con- centration was operated. In Sonoma county the chief producer was the Great Eastern Quicksiher ]\Iinino- Company. The total output of the ct>unty during the year was 1,519 flasks. A number of old mines were reopened in the Pine Flat district. Other producino- QUICKSILVER. 655 mines were the Cloverdale, the Great Western, and the Socrates. Development work of the Pacific Companj^ on property adjoining that of the Crystal Company was so satisfactor}' as to warrant the erection of a furnace to treat the ore. A new modified Livermore furnace was completed at the Culver Bear property. In Trinity county, which contributed a small amount to the total output during the year, the Altoona Company treated ore from the surface workings and the dumps. Con- siderable development work was accomplished b}' the Boston, Integral, and several minor concerns. The balance of the total output of California was obtained in Solano county. Several new mines were added to the list of producers during 1902; those contributing an output of 100 flasks or more being the Helen mine in Lake county, and the Silver Creek mine in Santa Clara county. Other quicksilver companies reported to have started operations in 1902 were the Monterey Quicksilver Mining Compan}^ near Idria, San Benito county; the Modoc Chief mine, near Redding, Shasta county; the Mariposa and Elizabeth mines, and the LTncle Sam and Eureka mines, near Cambria, San Luis Obispo county; and the Summit, Adobe Valley, and Orestimba properties, in Stanislaus county. A deposit of quicksilver ore of good qualitj' was reported in Modoc county, 25 miles east of Cedarville, in the extreme north- western part of the state — an entirely new section for the occurrence of cinnabar. As to the future of the quicksilver mining industry of California the larger and better known mines have in a measure been worked out, and it is hardly within the range of probability that other mines' equal in extent to the New Almaden or the New Idria will be discovered. Yet, on the other hand, there are manj' smaller mines which, by contributing from 20 to .300 flasks each per month, supply a considerable quantity of metal in the aggregate. Furthermore, the improve- ment in metallurgical and mining practices during recent j^ears, which permits the profitable treatment of very lean ores, will probably maintain the quicksilver industry in an important economic position for manA^ years to come. It is stated in general that quicksilver can be produced in California at a mining and smelting cost of $.3 per ton of ore, which renders it possible to treat with profit ores containing from 0.3 to 0.6 per cent of quicksilver; in a few cases it is possible to treat even lower grade ores and yet make a profit. The gen- eral statement is made that a modern furnace, operat- ing on average ores, pi'oduces quicksilver at a cost of $35 per flask not including interest on capital invested in the plant and property, or the cost of development work at the mine. In Oregon the sole producer of quicksilver in recent years has been the Black Butte Quicksilver Mining Company, which opened a quicksilver mine in 1898 on a spur of the Cascade mountains at Black Butte, Lane county. A modern iO-ton shaft furnace of the inclined shelf type was installed, but after a few months it was closed foi' altei'ations, the condensation of the ([uicksilver Jx'ing too imperfect to render the smelting profitable. Operations were resumed in 1900. In that year the above-named company acquired the Elkhead mine, in Douglas county, 5 miles from Black Butte; this mine was equipped with a l((-ton Scott fur- nace. Considerable development work has been reported by this concern, but the operations have not been entirely successful, as onlj^ 75 flasks of quicksil- ver were produced in 1901 and none in 1902. The ore of the Black Butte mine is of low grade, the average rarely exceeding one-half of 1 per cent of quicksilver. The principal operating companies in Texas in 1902 were the Marfa and Mariposa Mining Company, with three 10-ton Scott furnaces; the Terlingua Mining Com- pany, with one 40-ton Scott furnace; and the Colquit- Tigner Mining Company, with one 10-ton Scott furnace. The cinnabar deposits of California Hill, Brewster county, near Terlingua post-office, 90 miles southeast of Marfa, were known to the Comanche Indians, who used them as a vermilion pigment. The knowledge of these deposits, however, was not recorded until 1891, when several Mexicans found a few pieces of cinnabar float and took them to San Carlos, on the Mexican side of the Rio Grande, whence they were sent to Chihua- hua, and their mineralogical character determined. Mr. George W. Wanless, of the Rio Grande Smelting Works, and Mr. Charles Allen, of Socorro, N. Mex., under the direction of the Mexicans, found the veins and located the first mineral claims. Shorth' after this Prof. William P. Blake described these deposits under the title "Cinnabar in Texas,"' the first important arti- cle concerning this subject on record. Considerable prospecting work was carried on in the district, but it was not until 1898 that the metal was produced in com- mercial quantities. In that year Lindheim & Co. made a few flasks of quicksilver in a crude furnace at Terlin- gua. Other concerns became interested in the develop- ment of the quicksilver deposits, and the output of the region was 270 flasks in 1899, 750 flasks in 1900, 2,932 flasks in 1901, and 5,319 flasks in 1902, thus making a total output of 9,271 flasks. The deposits of cinnabar at Terlingua are of two classes; one occurs in hard and durable limestone ai)d the other in soft and friable argillaceous beds. The ores are cinnabar, mercury, yellow sulphide, and ter- linguaite, and contain in addition several other mercury minerals, such as calomel, eglestonite, and montroy- dite, which, on account of their rarit}', are of scientific interest only. Cinnabar is the principal mineral and is usually mixed with clay or iron oxide. Native mer- cury is present in several localities in the district, oc- curring in the interstices of crystalline calcite, and a single cavity in the calcite veins has yielded as much as ' Transactions of the American Institute of Mining Engineers Vol. XXV (1895) , pages 68 to 76. 656 MINKS AND QUARRIES. ::iO pounds of the native metal. The associated gano-ue is composed of calcite, anigonite, gvpsuin, and occa- sionally a little barite; iron oxidi\ pyi'ite, and occasion- ally arsenic and manganese minerals. The methods of mining in the Terlingua district up to the present time have been extremely crude. The work- ings h^-ve been confined mainlj' to the open cuts on the surface, but a few shafts have l)een sunk to a depth of from eighty to ninety feet and the ore obtained by drift- ing along the vein. The material mined is carried to the surface in rawhide buckets on the backs of Mexican miners, who climb notched-pole ladders with great agility. The veins are generally quite narrow, often less than one foot in width. The mined ore is sorted by hand, arranged into piles according to richness, and transported to the furnace plant, where it is first crushed in a Blake crusher, operated ))y gas engines, which ai'e more convenient than steam engines on account of the lack of watei" and fuel. The crushed ore is then con- vej'ed to the ore bins, which are situated abo\'e the le\Hd of the furnace, and from there, as rei{uircd, it is dumped into cars and charged into the furnace thrimgh Imppers. Formerly the very rich ore was treati'd in a I'ctort, a method so wasteful and entailing such costly repairs that it has been supplanted almost entirely hy shaft furnaces of the continuous type similar to the Scott- Hiittner furnace used in California. The greater part of the ore is treated in a shaft furnace b\- air oxidation, in some cases lime being added to aid in the decompo- sition of the sulphide. A very small proportion, con- sisting of extremelj' rich pieces, is treated in a furnace of the retort type. The development of the ([uicksilver mines in this region has been seriously hampered by the scarcity of water and the lack of fuel, mesquite wood ))eing al:)out the sole supplj- of the latter. However, coal and asphal- tum have been found within a few miles of Terlingua. and there is a possibility that oil may be discovered, as the formation closely resembles that of the Corsicana oil fields. THE QUICKSILVER INDUSTRY IN FOREKiN COUNTRIES. In Spain, 9(t per cent of the total production of quick- silver is obtained from the Almaden mines, in the prov- ince of Ciudad Real, which have been worked intermit- tently during the past two thousand years. The mines are owned b\- the Government, and the output is con- trolled liy the Rothschilds, who lia\'e been operating the mines under a ten-year concession, which was c(nitinued in 1900. The ores ai-e veiy rich, averaging about IS per cent of metal. Tli<' furnaces are not operated during the hot season, fi'om May to Septembei-. Mining is conducted with a view to permanency, and masonry is fi-eely used in the \ai-ious galleries and chambers of tile mines. It was not until IS'.tC, (hat machine di'ills were installed. In Austria, the cinjialiiir (li'))osits of Idrja, in Krain, were first mined in 14H0, and shortly afterwards were placed under Government ownership and supervision. Those mines furnish by far the greater part of the total output of quicksilver in Austria, only a small quantity being supplied by the mines in Hungary. The ore of the Idria mines is separated by hand into three clas.ses, namely, (1) a small proportion of high grade ore, con- taining al)out.S.5 per cent of mei'cury; (2) coarse ore, containing about thirty-five hundredths of 1 per cent of mercury; and {?>} fine ore, containing sixty-five hun- dredths of 1 per cent of mercuiy. In recent years the annual average content of the concentrated ore treated in the furnaces has varied from seventy-five hundredths of 1 per cent to 1 per cent of mercury. In Russia, the entire output of quicksih'cr is oVjtained from the mines of A. Auerbach & Co., situated near Nikitovka, on the Kursk-Kharko\' Railroad, government of Ekaterinoslav, in the southern part of European Rus- sia. Ill ancient times these deposits were exploited lij' the GriH'ks, but the present industry was not inaugu- rated until 1883. The average content of mercury in the ores extracted approximates four-tenths of 1 per cent. In Italy, the important ([uicksilver jjroducers are the Castelazara and Ripa mines in the Monte Amiata dis- trict, and the Vallalta mine in the province of Venice. The mines at ]\Ionte Amiata were originally worked by the Etruscans, and active operations are on record for the period from lOOO to li'uo A. D. The present industry l>egan at Side in 1.S4en worked by two concerns, the C\)m])anui de Minas de Azogue de Guadalcazar and the Compania de Nueva Potosi. The ores in this district, which contain an average of from 2 to 3.5 per cent of mercury, are smelted in a retort furnace provided with dust boxes, condensers, and a. numlier of brick settling chambers e(|ui|ii>ed with bafile plates. Tlie snu^lting process is l)rimiti\'c and wasteful, yet labor and fuel are so cheap QUICKSILVER. 657 that the operations are carried on with financial profit. The old mines, worked by the Nueva Potosi Company, are reported to contain immense bodies of easily acces- sible cinnabar ore", carr^'ing an average of 1 per cent of meiTury. The plant of this compan}- is equipped with two 6-ton furnaces. In China, Australia (New South Wales), Algeria (Taghit), Brazil, Peru, and Colombia deposits of cin- nabar have been reported from time to time, but in general, because of the inaccessibility of the vai'ious districts in which the deposits are located, they still await development. A small output of cjuiclisilver was obtained early in 1902 by an English company operating the cinnabar deposits in the province of Kweichau in southwestern China.

Occurrence. — At the time of the Eleventh Census platinum was known to occur in the United States in the following' localities: California — Butte, Del Norte, Humboldt, Mendocino, Plumas, Sierra, and Trinity counties; Idaho — Wood river country. New York — near Plattsbnrg; North Carolina — Burke and Rutherford counties; and Oregon — Coos, Curr}', Josephine, and Lane counties. In addition to these localities in the United States, there was a platinum product greater than that from the United States which helped to sup- ply the American market from the region of Granite creek, British Columbia, and the copper ores from the Sudbury district of Canada also brought in some plati- num and palladium in the nickel-copper matte imported into the United States. Associated with these platinum ores were occasion- ally found the allied metals — osmium, iridium, and pal- ladium. About 1898 the demand for platinum became more considerable and the search for it, and especiall}' for the allied metal osmium, became vigorous. It re- sulted in much prospecting in the Eastern states, as well as in the West, and many assays of supposed platinum ores, made bj^ Mr. A. W. Johnston,' showed that certain rocks in eastern Pennsylvania, eastern New York, and in many other localities contained traces of platinum. The one event of importance in the development of the platinum industry' in the United States was the dis- covery bj' Dr. L. D. Godshall, manager of the Boston and Wyoming Smelter, at Encampment," that the cop- per ores and matte of the Kambler mine. Grand En- campment district of Wj'oming, contained platinum and palladium. These ol)servations were confirmed \>^ Professors Wells and Penfield, of Yale University, •'' who separated sperrjiite (platinum diarsenide) from this Rambler ore. Further investigations by Mr. Johnston and Pi'ofessor Kemp showed that the ore of 'James F. Kemp, United States Geological Survey, Bulletin 193, pages 31 and 33. '•'Engineering and Mining Journal, Vol. LXII, page 843. ^ American Journal of Science, fourth series, Vol. 13, 1902, page 95. the Rambler mine contains platinum intimately mixed with all the copper ores and even the chalcopyrite, which apparently was the original copper ore in this mine, also contains platinum. This confirms an obser- vation of the writer in 1899 to the effect that platinum occurs in the pyrite grains found in certain hydraulic mines on the Trinity river in California, notably in the mine of Mr. F. Huertevant. These observations have led the searchers for platinum to examine a great many deposits of pyrite in the United States with the hope of finding them commerciall}' rich in platinum, how- ever, without commercial result, so far as the writer is informed. This work is referred to, however, as indi- cating a direction of search for platinum which may yet prove profitable. At the time of the Twelfth Census, therefore, the supply of platinum to the United States market, in addition to the importations from Russia and small importations from South America, consisted in the supply of platinum obtained from the localities in Cali- fornia and Oregon mentioned above, a small product from the Granite creek district, British Columbia, and a more considerable product obtained in refining the nickel-copper matte from the Sudbury district of Can- ada. The platinum deposits of Russia, which afford the principal supply of the world, have lately been described by Mr. Chester V. Purington in the Engineering and Mining Journal, Vol. LXXVII, page 720. A complete description of the occui'rence of platinum in all parts of the world is given by Prof. J. F. Kemp, of Columbia College, New York, in Bulletin 193, United States Geological Survey. The writer made an investigation in 1899 as to the proportions of platinum, osmium, and iridosmium pres- ent with gold in various parts of the West, and, supple- mentary to this. Dr. Waldron Shapleigh determined the proportion of osmium to platinum in many of the same samples, the results of which are given in the followino- statement: * 'Transactions of the American Institute of Mining Engineers, Vol. XXX, page 708.

Production. — From the domestic ores in the United States the product during- 1901! was 94 ounces, valued at $1,814. This was obtained as a side product in placer gold mining, and as the production is en- tirely dependent upon the more important produc- tion of gold this great .decrease in the quantity of the platinum produced, as compared with 1,108 ounces in 1901, is easily understood. In fact, the product during the last few years has varied most widely both in quantity and in the value of the product. The variation in value has been due not only to the real fluctuation and gradual increase in the price of refined platinum, but particularly to the fact that the value given has been that of the crude grains as collected and which vary widely in their contents of pure platinum. In addition to the platinum product of 1902, 20 fine ounces of iridium were obtained. In 1901 the corresponding product was 253 ounces of iridium. The production of platinum in previous years, as collected by the United States Geological Survey, is quoted in the following table: Table 1. — Production of ciiide platinum in the United Stateif, ISSO to 1900, and of refined metal from domestic ores in 1901 and 1902.^ Table 3. — Production of platinum in Russia: lS34to 1901.

Prices. — Since the close of 1899 the price of platinum has steadily increased, reaching its maximum value in January, 1902, when the price in New York was ^20 to $21 per ounce for ingot platinum. The price fell to $19. .50 in February, andin June to $19, which price pre- vailed to the close of the year. Best hammered plati- num was quoted as follows: January, 1902, .s2 cents per gram; June, 76 cents; July, 74cents; August, 73.5 cents; and December, 72.5 cents. Osmiridium is quoted at from S6 to $10 per ounce. This gradual increase in the price of platinum during the past ten years is due to the fact that there has been found no metal or alloy which will take the place of platinum, and also to the fact that there is such a limited supply and increased demand. The price of platinum is practically determined b}' Johnson, Matthey & Co., of London, who are refiners of a large portion of the Russian output. hoparts. — The following table gives the ini])orts of platinum into the United States from 1880 to 1902, as reported by the Bureau of Statistics: Table 3. — Platinum imported and entered for consumption in the United States: ISSO to 1903. calendar years, since 1886; pre- vious YEARS END JUNE 30.

By Edward W. Parker. The census of mines and quarries talien under tlie act providing for tlie Twelfth Census — the first of the twentieth centur}- — found tlie United States lirmlj^ es- tablished as the principal coal producer of the world. At the taking- of the Tenth and Eleventh censuses the United States was second in coal producing impor- tance, with Great Britain first. At the Kinth Census it was exceeded in production l)y both Great Britain and Germanj'. During the calendar year 1902, which is the period covered bj' the Twelfth Census of the mining industry, there were 27 states and 3 territories which contributed to the coal production of the United States. Of this number there were 5 in each of which the production amounted to less than 100,000 tons; there were 4 others in which the production was less than 1,000,000 tons; 5 states produced more than 10,000,000 tons each, and 1, Pennsjdvania, produced more than 100,000,000 tons. According to the character of the output, the coal fields of the United States conveniently fell under two great divisions, the anthracite and the bituminous. The areas from which the bulk of the anthracite is obtained are located in the eastern part of Pennsylvania, and or- dinarily when reference is made to the anthracite fields of the United States those of eastern Pennsylvania are meant. There are, however, two small areas in the Rocky mountain region where true anthracite is pro- duced in small quantities. One of these areas is in Gunnison county, Colo. , the other in Santa Fe county, N. Mex. But, although the product of these two lo- calities is true anthracite, the quantitj' obtained is so small that it is customary to include it with the bitumi- nous production, and it is so included in this report. The bituminous coal production shown here includes, in addition to the true bituminous coals, coking or non- coking, such varieties as semianthracite, semibitumi- nous, cannel, splint, and block coals, and lignite or brown coal.

Two pronounced discrepancies appear in the forego- ing tables. The first of these is the marked decrease in the number of mines reported for 1902, as compared with 1S89. This decrease is due to the elimination, at the Twelfth Census, of a large number of small banks producing an insignificant amount of coal for purely local consumption, which were included in the previous census. .It the taking of the Kleventh Censns it was possible to make use of the enumerators to secure reports from these unimportant producers, but as the mining investigation ;it the Twelfth Census was not taken for the same year as that of populati;)n and man- ufactures, it was not possible to secure the services of enumerators to get the returns from these widely distributed and unimportant sources. Neither was it possible to obtain anything like complete reports by correspondence, and to have employed special agents for a complete canvass would have entailed an expense entireh' out of proportion to the value of the results to be accomplished. The output from these small banks amounts to less than 1 per cent of the total, and to have made a complete canvass would have increased the cost of the investigation by probably 100 per cent. It would also have required a much longer time tlian could be allowed in order to complete the report within the time prescribed by law. The second discrepancy requiring explanation is that existing between the number of wage-earners reported for 1902 and 1889. The difl'erence is particularly noticeable in the statistics of anthracite production, where the number of wage-earners in 1902 appears to have been only 56.3 per cent of the number employed in 1889. In the bituminous mines, which increased 172.1 per cent in production, the number of wage- earners app(^ars to have increased only fj2.4 per cent. This makes it appear that in 19()2 there were 861 tons of coal produced for each wage- earner employed, as compared with 4:76 tons in 1889. The reason for this is in part that, following the custom employed in the other reports for the Twelfth Census, the working time was assumed to have been three hundred days in the year, and the mimher of wage-earners 'had been equated in accordance with this assumption. In 1889 the average number was calculat(Hl for the actual time the mines were in operation and not for the whole year. The report of the United States Geological Survey, which has not been e(iuat(Hl after the manner of the Twelfth Census, shows the average number of emploj'ees tohave been 14.S,141 in the anthracite mines and 370,056 in the bituminous mines. The average time worked was one hundred and sixteen days in the anthracite mines and two hund.-ed and thirty days in the bituminous mines. The total number of men employed, according to the report of the Survey, was 518,197, and tlie general average time worked was one hundred and ninety-seven days. It is to be notetl that the statistics for 1902 show a markefl increase over 1889, Itotli in the number of sala- ried ofhcials and in the amount paid in salaries. This is explained by the fact that in 1889 only the salaried force employed at or in the immediate vicinity of the mines was included. On the other hand, officials and salai'ied employees in central offices or at a distance from the mines were included at the Twelfth Census. In 1889 the office forces at the mines numbered 2,936 persons, who were paid $2,193,870 in salaries. The salaried list at the census of 1902 included 17,427 per- sons who received $17,419,217. Comparable statistics for the two censuses include those for wages, for con- tract work, for miscellaneous expenses, and for sup- COAL. 667 plies and materials. In 1889 these items aggregated 1144,34:3,4:10, and in 1902, 128.5,470,336, making an in- crease for the period included between those dates of 1141,127,926, or 97. 8 per cent. During the sameperiod, however, there was an increase of 129.1 per cent in the value of the product and of 113.5 per cent in the ton- nage, due to the unusual conditions of the market in 1902. The foregoing statistics of expense do not in- clude expenditures connected with the marketing of the product.

For more than five months, or from May 12 to October 25, mining operations were almost entirely su.spended in the anthracite region, the idleness being due to a strike among the mine workers. On account of the practi- cally complete cutting off of the supply of anthracite, there existed, during the latter half of the 5'ear, a scarcity of fuel which amounted in manj' parts of the Eastern states to an actual famine. The strike was finally settled by the friendly and personal intervention of the President of the United States, who with the consent of the operators and the leaders of the striking miners appointed a commission "to inquire into, con- sider, and pass upon the questions in connection with the strike in the anthracite region, and the causes from which the controversy arose." Operations were re- sumed immediately upon the appointment of the com- mission, but owing to the necessity for repairs and for pumping water from many of the mines, occasioned by the long period of idleness, it was several weeks before normal conditions were restored.^ The average number of all wage-earners emploj-ed during July, 6,493 — which was the minimum — closely ^Thia matter is thus briefly referred to here, partly because of its historic interest, but chiefly because the conditions are re- flected in the statistics presented in this report and require some explanation. The report of the commission has been published and can be had upon application to the United States Commissioner of Labor. It contains some interesting statistical tables on the subject of wages paid to the different classes of labor, on the cost of living in the anthracite region, and other details which will be found useful to anyone interested in the study of the anthracite industry. 668 MINES AND QUARRIES. approximates the average number of engineers, tiremen, and otl^er mechanics for the year, which was (i,513. The bituminous industiy also shows that the minimum number was employed in July; the range, however, was not great, the minimum being less than 9 per cent below the average for the year. Of all employees engaged in the coal industry, 19.9 per cent were employed in anthracite mines, and 80.1 per cent in bituminous mines, while employees in the anthracite industry received onlj' 17.5 per cent of the total amount paid in salaries and wages, leaving 8;^.. 5 per cent for those engaged in the bituminous industry.

Of this total, 41,373,595 tons, valued at §76,173,586, wej-e Pennsylvania anthracite, and 260,216,844 tons, valued at $290,858,483, were bituminous and lignite coal. Com- pared with the output reported at the Eleventh Census, the total production of coal in the United Statej in 1902 showed an increa.se of 160,360,926 short tons, or 113.5 per cent. This increase was all in the production of bituminous coal and lignite, for, on account of labor troubles in the anthracite fields of Pennsylvania, the output of anthracite in 1902 was restricted to about two-tliirds of the normal production, and was less than that of 1889 by 4,226,892 short tons, or 9.3 per cent. The production of bituminous coal in 1902 was abnor- mally stimulated by the scarcity of anthracite. Owing to the continuous activity and expansion in nearly all lines of manufactures, an increased production of bitu- minous coal would naturally have resulted, but would probably not have reached the amount it did had it not been for the fuel famine, especially in the Eastern states. On the other hand, conditions would have been greatly improved and the production and supply of bitu- minous coal would have been considerably increased had the transportation companies been able to meet the demands put upon them. The productive capacity of the bituminous mines could easily have supplied all the fuel needed had it been possible to get the product promptly to the consumer. The production of bituminous coal in 1902 amounted to 260,216,844 short tons, valued at the mines at $290,- 858,483. As compared with 1889, when the production was 95,629,026 short tons, valued at $94,346,809, these figures show an increase of 164,587,818 short tons, or 172.1 per cent in amount, and of $196,511,674, or 208.3 per cent in value. The relatively higher value of the product in 1902 was due partly to the improved indus- trial conditions in that year, and partly to the increase in prices naturally resulting from the curtailment in anthracite production. The average price per short ton for bituminous coal in 1902 was $1.12, as compared with 99 cents in 1889. The following table is a summary of production of anthracite and bituminous coal as reported at the last six censuses: Table .5.— PRODUCTION OF ANTHRACITE AND BITrillNOUS COAL: 1850 TO 1902.

The mining census for the calendar year 1889 showed a coal production of 141,229,613 short tons and the population census for the fiscal year ending June 30, 1890, showed a total of 63,069,756 persons, the per capita produc- tion of coal being 2.26 tons. The Twelfth Census reported a population of 76,303,387, the United States Geological Survey reporting for that j'ear a coal pro- duction of 269,684,027 short tons, or 3.53 tons for each inhabitant. If the population for 1902 be estimated at 78,576,436, the per capita coal production is shown to have been 3.84 tons for that year. It must be remembered that within the last thirty years, during which the coal production has so markedly outstripped the growth in population, petroleum and natural gas have been produced in enormous Cjuantities and to the value of many millions of dollars annually. The increased output of these fuels, however, has been partly offset hy a decrease in the amount of wood used for fuel, but while it is known that such a decrease has taken place, there are no statistics by which compar- isons can be made. The following comparative statement shows the aver- age production per mine and per employee from the statistics given in Table 1: Average production per mine and per emploijee for each censns year: 1S50 to 1903.

Of the miners 15,285, or 86 per cent, were paid from |1.75 to $3.71 per day, the largest number embraced within a single rate group 3,776, or 21.3 per cent of all miners, receiving from $2.25 to $2.19 per day. There were 1,185, or 6.7 per cent, who received paj' at the rate of $3.75 or more per day. A 3022.3—04 43 larger number of miners' helpers were included in the rate group of $1.75 to $1.99 per day than in any other group, and 91.9 per cent of the miners' helpers, or 6,361 men, were paid from $1.25 to $2.49 per day. The range of wages for 1,853 engineers, 89.8 per cent of all reported, was from $1.50 to $2.71, and of the 1,836 firemen, 1,778, or 96.8 percent, received between $1.25 and $2.24. Of 2,613 machini.sts, blacksmiths, and other mechanics, 2.451, or 93.8 per cent, were paid between $1.50 and $2.74. The largest number of timbermen and track layers in one rate group, 624, or 31.6 per cent of all in this class, was paid from $1.75 to $1.99 per day, and 1,833, or 92.7 per cent, were reported at rates lietween $1.50 and $2.49 per day. The 4.564 boys under 16 years of age, comprised 6.5 per cent of all wage-earners. Of this number 2,006, or 44 per cent, received from $0.50 to $0.74 per day, and 4,467, or 97.9 per cent of the total number, were reported at rates between $0.50 and $1.24 per day. The group of (i74 MINES AND QUARRIES. "all other Avage-earners" comprised 45. s per ('(Mit of tlie total imiuher of wage-earners reported. Their wages rano-ed froni less than $0.50 per day to $3.49 per day, but S3.1 per cent received from $1 to $4.99, while only 9.5 per cent received $2 per day or over and rjut 7.4 per cent less than $1 per day.

The classification of the Sullivan county product as anthracite has given rise to some contention. This coal lies in an isolated district known as the Bernice basin, in the northeastern part of Sullivan county and extending into the southeastern part of AVyoming ' In previous years some coal which was classed as anthracite was mined in the eastern part of Rhode Island, and in Bristijl and Plymouth counties in Massachusetts. This product is, however, in reality of a graphitic quality and not anthracite. It is not now mined for fuel purposes, and the production is included with that of graphite. county. Its pliysical characteristics are more like semi- anthi'acite than true anthracite, but on account oi its- high percentage of fixed carbon and low percentage of moisture it is classed as an anthracite liy the Second Penn.sylvaniatreological Survev, and it is so considered in this report. In a general wa^^ the anthra(^ite coal field ma}' be said to be bounded on the north by the north branch of the Susquehanna river, on the east by the Delaware and Lehigh rivers, and on the west by the Susquehanna river. These rivers, together with the Schuylkill, form the di'ainage outlets for the region. The entire anthra- cite I'egion embraces a territorj' of about 3,300 square miles, but less than one-sixth of this total area, or about 484 square miles, is underlaid by workable deposits of coal. The productive portion is not in a continuous area, but consists of a number of detached valleys or basins, the general trend of which is about 60'^ N. to 70-" E. They are arranged en echelon, from NE. to SW., for a distance of 120 miles. The greatest width is 30 miles, from ^Nlauch Chunk to Shickshinny. or 50 miles if the Bernice basin in Sullivan county be considered as a portion of the anthracite field proper. The anthracite coal fields, exclusive of the Bernice basin, are divided into 3 general trade regions, known as the Wyoming, Lehigh, and Schuylkill. Ceographi- cally these regions are subdivided into 4 well-defined fields or basins, known as the Northern, Eastern Middle, SJ'>')'2 Number of operators i 1,10'^ Salaried otricials, clerks, ete.; Number ' 11,413 Salaries , if 14,.

This table .show.s that the majority of adult wage- earners received wages between 11.75 and $2.74. In- cluding all occupations, the largest number em- braced in a single rate group was reported as receiv- ing from $2 to $2.24 per da}-, 2.5.:^ per cent falling in that group. From this rate the numbers decreased regularly as the rates of pay decreased below $2 or increased above $2.2-4. In the class of engineers TU.4 per cent were employed at daily rates ranging from $2 to $2.74, and in the class of firemen 73.5 per cent at rates ranging from $1.50 to $2.24 per day. Of the 6,739 machinists, blacksmiths, carpenters, and other mechanics emploj'ed, 4,404, or G5.4 per cent, were paid from $2 to $2.74 per day. The miners constituted 67.4 per cent of all employees; the largest number in any rate group apjDear to have received from $2 to $2.24. But on account of the mining being done on a tonnage basis the daily rates of pay are largely estimates and averages. There was paid as wages for the mining of bituminous coal on a tonnage basis the sum of $128,055,854. The daily rates of pa}- to miners' helpers show a distribution over a much wider range than is the case with other occupations. Of the timbermen and track layers 5,220, or 66.6 per cent, were paid at rates ranging from $2 to $2.49, and 90.3 per cent received from $1.50 to $2.74 per day. The 5,62S boys under 16 years of age con.stituted 2 per cent of all employees; 74 per cent received from $0.75 to $1.24 per day. The remaining wage-earneis, classitied as "all others," com- prised 60,625, and constituted 21.6 per cent of all wage-earners, and 77.5 per cent of the number were paid at dailj^ rates ranging from §1.50 to $2.4'.t. As shown in Table 60 the largest number of men. for the industry as a whole, was employed in December and the smallest inimljer in July, the maximum and minimum numl:)ers lieing only about 7 per cent above and l)elow the average number. Michigan showed a heavy falling off from April to August, but as a rule the states do not show any wide fluctuations. Coidract vHirlx. — The expenditure for contract work amounted to $1,244,114, and 5,040 men were employed thereon. This was for tunneling, shaft sinking, and like work done under contract. Hiq)2)l.lt'H^ 'inaferiiils, and inisreJluneovH expenses. — The cost of supplies and inaterials rej^orted amounted to $24,798,922, or 10.4 per cent of all expenses, and was the large.st item next to the amount paid for salaries and wages. The amount expended for miscellaneous expenses, $16,774,459, comprised $7,442,089 for royal- ties and rent of mine and mining plant, and $9,332,370 paid for rent of ofBces, taxes, and other sundries. Mis- cellaneous expenses foi'med 7 per cent of all expenses. Production lii/ states. — In the following table is .shown the total production of bituminous coal by states dur- ing 1902, the distribution of the product for consump- tion, and the value and average price per ton at the mines. 680 MINES AND QUARRIES.

The followino- i,s a review of the production of bitu- minous coiil in the .several state.s and territories: Aldhama. — The coal fields of Alabama belong to the great Appalachian system, which extends from the northern part of Pennsylvania to the central part of Alabama. The coal bearing formations which become quite narrow in passing through Tennessee widen out suddenly in the northern part of Alabama and cover about 50 per cent of the northern half of the state. The total coal area of Alabama is estimated at 6,500 square miles. There are 19 counties, all north of a line drawn midway across the state from east to west, which are underlaid h\ coal. In only 11 of these, however, is coal produced at present on a commercial scale. These 11 counties are Bibb, Blount, Cullman, Etowah, Jefferson, Marion, St. Clair, Shelby, Tuscaloosa, Wal- ker, and Winston. The coal producing region is divided into 3 distinct basinsor districts, which are known l)y the names of the rivers which drain them, the Black War- rior, the Coosa, and the Cahaba. The Wariior district is the largest, but the Cahaba is the principal producer, the county of Jefferson, which includes the city of Bir- mingham, in the Cahaba district, contributing more than 50 per cent of the state's total output. All of the coals of the .state are classed among the bituminous varieties. Some are coking coals of good quality, and to these is due the rapid growth of the iron and steel industries of the state. The development of these industries and of coal mining in Alabama during the last quarter of a century has been one of unusual rapidity. The cen.sus of 1.S40 reported a production of coal in Alabama for that year, of 94fi tons, and at the cen.sus of 1(S60, 10,200 tons were reported.

(Franklin order to avoid disclosing tlie operations of individual operators.) California. — All of the coal mined in both California and Oregon is of the lignite variety. In California there are a number of rather widel}- separated tields, the chief of which arc the Mt. Diablo tind Corral Hol- low. The principal production in 1902 was from Ala- meda and Contra Costa counties, the foi-iner jiroducing about SO per cent of the state's total output. Smaller amounts were mined in Kern, Monterey, Riverside, and Siskiyou counties. In a num})er of other counties coal veins have been prospected, and the counties of Amador, Butte, Del Norte, Fre.sno, Orange, and San Diego have produced some lignite coal in the past. Tliese mines, however, have been abandoned from one cause or another, principally the quality of the coal, although there was also difhculty in the mining. The Corral Hollow held, \yhich Is the one in Alameda county, has a considerable advantage, on account of its proximity to San Francisco, where the product hiids its principal market. The total production of lignite in California during 1902 was only S1,9S1: short tons, as compared with 119,820 short tons in 1SS9. The comparatively small coal mining industry of California is subjected to influence.s which cki not atl'ect other .states. One of these is the exportation of wheat from the Pacific seaports. Vessels carrying wheat as an outgoing cargo are apt to bring back, at a low rate of freight, coals from Australia or Japan. When such is the ca.se the demand for California coal falls off. In the years 1S99, 1900, and 1901, according to the reports of the United States Geological Survey, occurred the largest outputs of coal in the state of California since 1880. The production in 1902 was reduced much below that of these years on account of the large production of crude petroleum, the use of which for fuel purposes in the manufacturing industries of the state developed very rapidly in 19(12. Colorado. — The coal fields of Colorado have ))een fully de.scribed bj- Mr. K. C Hills, in Mineral Resources of the United States, 1892. They have also been de- scribed in considerable detail by Mr. L. S. Storrs in the Twenty-second Annual Report of the United States Creological Survey, Part HI. Geologically, the coal bearing rocks of Colorado are confined to the Upper Cretaceous coal mea.sures and, with only few excep- ■ouuly had a production exceeding 200.000 tons, but is not shown separately in tions, to the Laramie formation in these measures. The coal bearing territory is found along )>oth the eastern and western iianks of the Rocky mountains. The coal producing areas are divided into 3 groups, the Eastern, Park, and Western, the tields of each group being separated by areas of gi'eat elevation and erosion. The groups are again subdivided into distinct fields, as follows: The Eastern group into the Raton, Canyon City, and South Platte; the Park group into tlio Middle Park and Como; and the Western group into th(^ Yampa. Grand rivt'r, and La Plata. The coal tields of Colorado contain every variety of coal, from the typical lignite to the true anthracite. Th(> arcii of the latter, however, is very small, Mr. Storrs stating that it probably does not exceed 80 square miles. Owing to the aggressive ])olicy of the Colorado Fuel and Iron Company, the coal tields of Colorado have been more thoroughly explored than those of any other state in i\w Rocky mountain region. Mr. Hills, in his rejiort on Mineral Resources of the United States, 18'.I2. estimates the available gross tonnage of the Colorado tields at -15,197,100,000 short tons, and esti- mating 75 per cent of this as recoverable, the net availalde supply is placed at 33,897,800.(100 tons.

Nearly three-fourths of the state of Illinois is un- derlaid by productive coal measures, the entire area b(dng estimated at 43,900 square miles. This is the largest coal bearing area recorded for any state of the Union. There are more counties in this state in which coal is produced than in any other of the United States, the production in 1903 being reported from 54 ditferent counties. In 9 of these the production exceeded 1,00<»,000 tons, and in 9 more the production was be- tween 500, OOU and 1,000.000 tons. The ctwil is princi- pall\' bituminous, of the dry, noncoking \aiiety. In 1903 the state was the second in importance among the coal producing states, being outranked only V)y Pennsylvania. Its production was 10.9 per cent of the total production of the United States; the \'alue was 9.3 per cent of the total value. The output in VMVl amounted to 33,939, 373 short tons, valued at $33, 945, 910. At the taking of the Eleventh Census the production of coal in Illinois was 13,104,373 shoil tons, worth at the mines $11,755,303. The total production of the state during the census year 1S80 was 6,115,377 short tons, valued at |8,779,833.

Indiuii Territory. — The coal areas of Indian Terri- toiT form a portion of the Western coal field, and are directly connected with the coal fields of Kan.sas on the north and those of Arkansas on the east. The greater portion of the development has lieen in the Choctaw nation, in the territory tributary to the Missouri, Kan.sas and Texas Railway and the St. Louis and San Francisco Railroad, which cross the territory from north to south, and to the Choctaw, Oklahoma and Gulf Railroad, crossing it from east to west. Workable areas also underlie about half of the Chero- kee nation, all of the Creek nation, and the northeast corner of the Chickasaw nation. The area underlaid by workable seams is estimated to contain about 14,8dlr8 square miles. The entire production in the territory was from the Cherokee and Choctaw nations, the latter contributing by far the larger portion. The first recorded produc- tion was in 1880, when the amount was reported as 120,947 short tons. By the time the Eleventh Census was taken this production had increased to 752,832 tons, or 50 percent; in 1902 it had grown to 2,820,666 tons. Of the amount of coal produced during 1902, 2,587,100 tons were loaded at mines for shipment; 25,998 tons were sold to the local trade and used by employees; 96,017 tons were used at the mines for steam and heat, and 111,551 tons were made into coke. The average price per ton received for coal was $1.51, as compared with *1.76 in ls,s9. Tiidiitna. — The coal fields of Indiana underlie the counties in the southwestern portion of the state and form a portion of the large Central coal field. Thei'e are said to be at least 8 workable coal beds, although as a usual thing not more than 3 of these are found in worka- ble thickness at any one locality, and generally there is only one bed that can lie worked from one shaft. The eastern part of the coal fields of Indiana is noted for its production of what is known as Indiana, or "Brazil" block coal, which is in favor as a domestic and steam fuel. This coal receives its name from the almost perfect rectangular likn'ks into which the coal naturally breaks because of the pronounced cleavage planes intersecting each other at right angles. Some cannel and some semiblock coal are also produced in this state. The production in 1902 amounted to 9,116,124 short tons, valued at $10.399, 660. In 1889 the production was reported by the Eleventh Census at 2,845,057 short tons, valued at |2,8M7,852, and the Tenth Census in 1880 reported the production of that year at 1,454,327 short tons, valued at !p2, 150,258. Tal.ile 25 shows by counties the total production of Indiana in 1902, the disposition of the same, and the total amount received for the coal sold, too-ether with the average price per ton at the mines. 686 MINES AND QUARRIES.

The total coal pro(hicing area is estiinaled at 20,000 square miles. The product is of the dry non- coking varietv of V)itumin(.)us (.-oal, with snuill amounts of block and cannel. A^'ith the exception of the block and cannel coals, the product is generally better adapted for steam raising than for' any other industriiil purpose. Some attempts have been nnide to coke the Iowa coals on a commercial basis, but owing to the competition of the higher grade product fi'oni other sources the at- tempts were not profitable and lia\'e been abandoned, and no coke has been made in Iowa since ls;»l, in which year 157 tons were prothiced. Tiie coals are usually high in both sulphur antl ash. Coal mining in Iowa began at quite an early date, an output of 360 tons having })een ycpovU-d as etirly as 1S40. The P^ighth Census showed that the jiroduction for 1860 was 41,920 short tons. l',y ls7o it had grown to 263.487 tons, and in ISSO to 1,461,116 tons.

I Lucas county had a yiroduction exceeding 200,000 tons, but is not shown separately in order to avoid disclosing the operations of individual operat.ors.) lunisii^:. — The Kan.sas coal areas lie entirely in the eastern portion of the state, the western ])ouiidaiT of the Western coal field traver.siiig' Kansas in an almost due north and soutli line from Marshall county, adjoin- ino- the state line of Nebraska on the north, to Chau- tauqua county, adjoining Indian Territory on the south. There are some isolated deposits in the central portion of the state, but the beds are thin and the coal is of inferior quality and not at present mined on a commercial scale. The laro-er portion of the pi'oduc- tion is obtained from the counties of Cherokee and Crawford, in the southeastern corner of the state, these 2 counties contributing about '.H) 23er cent of the entire output. These 2 counties are underlaid by the Lower Coal Measure's, which form the eastern portion of the Western tield, and which contain the most important and productive beds. The production of the state is used principally for domestic and railroad consumption. A small quantity of coke is made at irregular intervals in Cherokee county, the coke being utilized liy the zinc smelters in the immediate vicinity. The larger portion of the product is, like that of Iowa, of tlie dry, noncoking varietj' of bituminous coal. Coal mining as an industry in Kansas, so far as rec- ords are concerned, began in 1869, when, according to the report of the United States Geological Survey, 36,891 tons were produced. In 1880, at the taking of the Tenth Census, the production of coal in Kansas amounted to 771,442 short tons. In 188'.» it had in- creased to 2,221,043 tons. In 1902 it amounted to 5,266,065 tons. The development of the coal mining industry in Kansas, as in the adjoining .states, Iowa and Missouri, has kept pace with the increase of popula- tion and the establishment of manufacturing industries. The markets are restricted to a comparatively limited area, and the coal is not shipped to points far distant from the mines.

The average pi'ic(^ per short ton was Sl.Ot; in 190^!, as compared with fO.D'.l in 1901. In 1889 the average price per short ton was |0.8(3. Tlie bulk of tiie production was from Allegany county, only 2.7 pei- cent of the output in 1902 being from (jarrett count}'. Michigan. — All of what is known as the Northern coal field lies within the lower peninsula of the state of Michigan, between Lake Michigan and Lake Huron. It is estimated to contain an area of appioximately 11,300 square miles. It is the onl}- coal field known in the drainage basin of the Great Lakes and the St. Lawrence river. The coal is of an inferior quality, when compared with that of the Appalachian region, having a high percentage of both ash and sulphur. It is probably for this reason that the development of the region has been somewhat slow in comparison with that of other regions. It is reported that the portion of the field near Jack- son was producing coal as early as 1835, but it was not until 1808 that any estimate of the production was obtained. In that year the output amounted, it is stated, to 28,000 tons. The Census report of 1870 gave the jiroduction at 31,52S short tons. In 1880, accord- ing to the Tenth Census, the production was 1(.)0,800 short tons. In 1881 and 1882 there was a little increase, but for the next thirteen vears, according to the reports of the United States Geological Survey, the production not only did not increase, but showed a declining ten- dency, which was due undoubtedly to the excessive production and conse()uent low prices of coal from the fields having a better ([uality or lower cost of produc- tion. At the Eleventh Census, for the year 18X9, the output was only 07,431 tons. Since 1897, however, because of the higher prices of coal from other regions, and also because of the rajfid industrial growth of the cities on Lake P^rie and Lake Huron, the demand for. and the production of, ^Michigan coal have increased with notable rapidity. According to the report of the I'nited States (ieological Survey the production of coal in ^Michigan in 1901 was 1,241,241 short tons. A strike of the mine workers in 19o2 reduced the produc- tion of the state to 904.718 short tons.

Most of the deposits are of the Cretaceous age and vary from lignite to bituminous, the lignites usually- lieing in the plains region and the bituminous coals in the mountain ranges. The coal fields form a nearl}' continuous belt, and cross the state in a northwest-southeast direction. Little detailed investigation has been made and only a general idea can be formed as to the extent and value of these fields. The coal bearing areas are estimated to contain 32,000 square miles. Some of the coals possess excel- lent coking qualities, the coke being used in the smelters and refineries as far east as Omaha. The first statement regarding the production of coal in Montana is that made bj^ the Tenth Census, which shows that in 1880, 224 tons were produced. The active development of Montana's coal mines began in the latter part of the decade 1880 to 1890, and in 1889, accord- ing to the Eleventh Census, the production was 363,301 short tons, valued at $880,773, or an average of 12.12 per ton. In 1902 the production was 1,560,823 short tons, worth 12,443,447, or an average of $1.57 per ton. According to the reports of the United States Geological Survey the coal production of Montana reached the market limits in 1895, when it amounted to 1,504,193 short tons. Since that time the production has re- mained almost stationary, the maximum being attained in 1900, with a total of 1,661,775 short tons, and the minimum in 1901, when a total of 1,396.081 tons was produced. The statistics of production in 1902, by counties, with the distribution of the product for consumption, are shown in the following table: Table 37. — Coal p roduction of Montana, hij counties: 190S COUNTY.

New Me.rieo. — The coal producing areas of Isew Mexico are f^und in somewhat widely distributed fields or basins having seemingh' little connection with each other. The three most important areas are those in Colfax, Kio Arriba, and McKinley counties. The first- mentioned area is an extension southward of the Las Animas, or Trinidad, area in Colorado, and occupies the northwestern poi'tion of Colfax county. The La Plata field of Colorado, which is found in tlie southwestern portion of that state, suddenly turns at its eastern extremity and extends in a narrow strip almost due south, through Kio Arriba county and into McKinley county. Owing t(j its distance from railroad communi- cation, this area has not been extensively develo))ed. The Callup field, which occupies a long, narrow strip extending north and south in the western part of McKiidey county and into San Juan county on the north and Valencia county on the south, is one of the most extensively' developed areas in the territory. In addition to these there are the Los Cerrillos area, in Santa Fe county, and the Carthage area, in Socorro county, in both of which mining operations are carried on. These are the only fields which have been exten- sively developed, although there are some isolated fields of economic importance in the territory, where small amounts are mined for local consumption. The coals of New Mexico, like those of Colorado, range from lignite to anthracite. Tlie anthracite occurs COAL. 693 in the Los Cerrillo.s field, which ha.s been penetrated by volcanic intrusion in close proximitj' to the coal beds, with the result of altering the liituniinous coal to an an- thracite of good grade. This anthracite is sold as far north as Denver and as far west as San Francisco. In 1902 the production was 41,326 short tons. All of this anthracite occurs in the northern part of the Held. Toward the south the coal passes into coking and semi- coking varieties of Ijituminous coal, the transition being Yevj gradual and almost imperceptible. Good coking- coal was also produced in Colfax count}', the principal operations being near Raton. There were )S coun- ties in the territory which produced coal in lit(i2. In only 2, Colfax and McKinley, did the product amount to as much as 200,000 short tons during the year. No report of coal production in New Mexico was made at the Tenth Census, the first record of operations being that for the United States Geological Survej^ in 1882, in which year an output of 1.57,092 short tons was ob- tained. The production reported at the Eleventh Cen- sus, for 1889, was •±86,463 tons. In 1902 it was 41,326 short tons of anthracite and 1,007,437 short tons of bituminous, a total production of 1,048,763 short tons.

Worth Ctirolina. — The only productive coal field in North Carolina is a small area lying in the valley of the Deep river, just west of the point where it joins the Cape Fear river. The area from which coal may he produced is a narrow strip 30 miles in length. Another small area lying along the Dan river, near where it crosses the Virginia line, is known to contain some coal, but it has not been developed and is regarded as of lit- tle promise for the future. The only mine operated in the Deep river basin is the Cumnock, formerh^ known as the Egypt mine. It was opened in 1889, with a pro- duction during that year of 192 tons. Detailed statis- tics are not published separately, in order that the confidential nature of the reports to the Bureau of the Census may be maintained. Not'tli Dahita. — Although the coal producing areas of North Dakota are included in the Rocky Mountain fields they are not within the mountainous areas. They lie in about the middle of the state, in the great plains region. All of the coal produced in the state is lignite and disintegrates rapidly upon exposure. Under present conditions it can not be used .satisfactorilj' in locomo- tives, l)ut answers the need of the community for domestic fuel and for use under stationary- lioilers. Comparatively little labor is necessary to procure the coal, strip or surface mining being frequently prac- ticed. The coal mine operators have endeavored to improve the quality of their product by briquetting, but so far these attempts have been unsuccessful, fail- ure being due principally to the high cost of binding materials. No production of coal was reported from North Dakota at the Tenth Census. In 1889 the output was 28,907 short tons. This was almost entirely mined and used by the ranchmen in the immediate vicinity of the openings. In 1902 the production amounted to 226,511 short tons. The state of North Dakota has endeavored to foster its lignite mining industry by compelling its use in all state offices and institutions. 694 MINES AND QUARRIES.

Ever_y county in the eastern half of the state, with the ex- ception of a comparatively narrow belt of \ counties bordering on Lake Erie, is, or has been, wholly or in part, underlaid by coal. The entire area underlaid by coal in this state has been estimated at 12,000 stjuare miles, distributed over 30 counties in the eastern and southeastern portions. There are no less than 1(3 work- able beds contained in the coal measures of the state, but only 6 of the 16 are of importance. The other 10 are worked by siriall operators, producing coal for purelj^ local trade. The important beds are known as No. 1, the Block or Sharon coal seam; No. 2, the Wells- ton; No. .5, the Lower Kittanning; No. 6, the Middle Kittanning; No. 7, the UpjDer Freeport; and No. 8, the Pittsburg. The coals in these different lieds emljrace all the varieties of bituminous — steam, gas, coking, and cannel. The most important producing bed is the Middl(> Kittanning, or No. C. In Athens, Hocking, and Perry counties this bed is known as the Hocking Valley seam, which in the 3 counties mentioned produces from 35 to 40 per cent of the total output of the state. It is an excellent steam coal, is popular for domestic use, and also stands high as a furnace fuel, for which purpose it is used in its raw state. The thickness of this seam varies from 12 inches, in Columbiana county, to 13 feet in the Hocking vallcv. No. 7, or the Upper Fi'eeport, is second in importance. It is considered as one of the Iiest steam coals in the state, and is consumed chielly T)y the rtiilrotids. The principal development of this bed is in (iut>rnsey ct.mnty, which, in 1902, was third in importance as a coal producer. The Wellston, or No. 2, is also an important pi'oducer, the chief operations being in tlie \'icinity of Jackson and Wellston, in -lackson county. It is a free, open burning, noiicoking coal, used to a consideral)le extent in its raw state among the local blast fui'iiaces. It also stands high in popularity as a domestic fuel. The No. 1, or Block coal seam, produces a good steam and domestic coal, but its chief use is as a blast furnace fuel, for which purpo,se it is u.sed raw. The furnaces which first substituted coal for charcoal used this coal. What is familiarly known as "Mas.sillon" coal, in the northern part of the state, is mined from this bed. No. .5, or the Lower Kittanning bed, is best known for its coking qualities, it being the only coal in the state from which a fair grade of coke can be made. Little coke is made from it, however, owing to the proximity and cheapness of higher grade coking coals in Pennsylvania and West Virginia. The coal from this bed finds its principal use as a steam fuel. No. 8, or the Pittsburg seam, underlies the whole or parts of the counties of Jefferson, Harrison, Belmont, Guernsey, Athens, and Meigs, in the southeastern por- tion of the state. While not the most important coal bed in the state, it is looked upon as one of the chief future sources of supph', owing to the approaching depletion of some of the other beds.

Coal mining in Ohio began du-ing the first quarter of the nineteenth century, but the exact date of the first operations is not known. The fii'st shipment of whicli there is a record was made from Summit county in 1828, but it is not known how much coal was in this shipment. In 1838 the entire coal production was I'eported as 119,952 short tons. In 1840 the production was 140,535 short tons; in 18ti() it amounted to 1,133,596 COAL. 695 tons, and in 1870 it was 2,830,559 tons. Tiic^ Tontli Census reported an output of G,008,5!»5 short tons for the tiscal 3'ear ending June 30, 1880. The Eleventh Census, for the calendar year 1889, showed a produc- tion of 9,976,787 short tons, and in 1902 it reached the maximum record of 23.519,894 short tons. The value of the product in 1889 was $9,355,400, an average of $0.94 per short ton. In 1902 the product was \-al- ued at 126,953, 781^, or $1.15 per ton. It is not believed that the record made in 1902 will l)e greatly exceeded in the future, as much of the best coal land has been, or is rapidly becoming, exhausted. As will be seen from the foregoing taljle, there were 29 counties producing coal in Ohio during 1902. Fifteen of these ])roduced more than 200,000 tons each, thus contril)uting 22,626,215 tons of the total, or an avei'age of over 1,500,000 tons each. The 14 other counties produced 893,079 short tons, or an average of about 63,800 tons each. The total amount jmid in wages at the Ohio coal mines in 1902 was 116,693,464; other expenses reported amounted to $4,972,023, making a total of $21,665,487.

Oregon. — Oregon has only one productive coal field. This is known as the Coos Bay lield, in Coos county. It is directly on the coast, giving water transportation for the production, most of which is sent to San Fran- cisco, Cal. According to Prof. J. S. Newberry, coal was mined on Coos bay in 1855, but records of these earlier years are entireh' wanting. In 1889 the pro- duction amounted to 64,359 tons; in l'.H.»2 it was 65,648 tons, showing that the industrj- has not developed much during the last thirteen years. Penn.sylranid.. — The bituminous coal areas of Penn- syh'ania, which embrace nearly the entire western half of the state, form the northern extremity of the great Appalachian held. Every county in the state west of the Allegheny mountains contains coal beds of economic value, while several outlying basins east of the moun- tains ai-e also extensively mined. The eiitirt" bitumi- nous coal producing area of Pennsylvania is estimated to contain about 15,800 stjuare miles. In the northern portion of the state the deposits are found principally in detached basins scattered through the counties of Bradford. Cameron, Clinton, Crawford, Elk, Forest, Lycoming, Potter, Tioga, Venango, and Warren. To the south and southwest of these the coal bearing rocks cover all, or nearlv all, of the counties of Allegheny, Armstrong, Beaver, Butler. Caml)ria, Clar- , ion, Clearfield, Fayette, Greene, Indiana, Jefferson, Mercer, Somerset, Washington, and Westmoreland, and portions of Blair and Center counties. The Hunting- don, or Broad Top, basin lies east of the main coal fields, in Bedford and Huntingdon counties. The counties of Allegheny. Fayette, Greene, Wash- ington, and Westmoreland, in the southwestern corner of the state, contain the upper productive measures, in which is found the famous Pittsburg bed, probably tlie largest and most productive single coal seam in the world. It is from this bed that the cele))rated Youghio- gheny gas coal of the Pittsburg district, in AUegheiw and Washington counties, is obtained. Farther to the east it produces the famous Connellsville coking coal of Fayette and ^Vestmoreland counties. In INIaryland it yields the well known Cumberland coal, while some of the l)est coals of Ohio and West Virginia are also mined from it. In fact, it may l)e said that in quality, as in (]uantity, the coal contained in the Pittsburg bed is etpud. it not superior, to ;iny l)ituiiiinous coal in the world. Among the other beds in the state are the Upper Freeport. Lower Freeport, Lpper Kittanning, Lower Kittanniug, Blossburg, Brookville, Sharon, ]\Iercer, Sewickley, and a number of other less important ones, all of which are described in detail in the Twenty-Second 696 MINES AND QUARRIES. Annual Report of the United States Geological Survey, Part in. In the production of coal Peiuisylvania far exceeds any other state. The con)l>inccl output of anthracite and bituminous coal in Peniisj'h'ania, from the begin- ning of the industry until ISH)^, has each year exceeded 50 per cent of the total production of the United States, the single exception in 1902 having ))een due to the decrease in anthracite production caused bj^ the long- strike. The bituminous product of the state alone has for many years been from 3.5 to 40 per cent of the total bituminous coal output of the country. In 1902 Penn- sylvania produced 9S,574:,3H7 short tons of bituminous coal out of a total of 260,216,844 short tons, the per- centage for the state being 37.9. In 1889 Pennsylvania produced 36,174,089 tons, or 37.8 per cent of a total of 95,629,026 tons. At the census of 1880 the total bitu- minous output was 42,831,758 short tons, of which Pennsj'lvania produced 18,425,163 short tons, or 43 per cent. The output of bituminous coal in the state of Penn- sylvania during the fiscal year ending June 3(), 1.^80, was, as stated above, 18,425,163 short tons and the value of this product was $18,567,129, or an average of §1.01 per ton. The total amount of wages paid during this year was $10,863,583. During the calendar year 1889, Pennsylvania produced a total of 36,174,089 short tons, or nearl}' double the output of the census year 1880. The value of this product at the mines was $27,953,315, or an average of $0.77 per short ton. The total amount paid in wages in 1889 was $20,738,647. In 1902 the total bituminous production of Pennsylvania was 98,574,367 short tons, or 2^^ times that of 1S.S9, and 5^ times that of 1880. The total value of the product in 1902 was $106,032,460, an average of $1.08 per ton, the higher value in 1902, as compared with that of th(_> pre- ceding censuses, being due priiicipall}' to the demand created for bituminous coal ))V the shortage in the sup- ply of anthracite. The total amount paifl in \vages in the bituminous coal mines of Pennsylvania in 19u2 was $59,848,902. In 1880 the average wage cost per ton of coal produced was 59 cents; in 18s9 it was 57 cents; and in 1902 it was 61 cents. In 18S(» the wage cost was equal to 58.4 pei' cent of the axerage selling price per ton; in 1889 the wage cost was 74 i)er cent of the selling- price; while in 1902, owing to the high values caused by the sti'ike in the anthracite region, the wage cost was only 66.5 per cent of the selling value. Of the 24 counties in Pennsylvania from which a pro- duction was reported in 1902, there were 2 counties, Fayette and Westmoreland, the output of which ex- ceeded 18,000,000 short tons each. Two other counties, Allegheny and Cambria, each exceeded 10,000,000 tons; 4 others, Washington, Clearfield, Jetlerson, and Somerset, each exceeded 5,000,o00 tons; and 4 more, Arm- strong, Center, Indiana, and Tioga, produced between 1,000,000 and 2,00O,00(.» tons each. The 2 counties of Faj-ette and Westmoreland, together, produced nearly 5,000,000 tons more than the entire state of Illinois, which was, in 1902, the second state in the production of coal, and 50 per cent more than West Virginia, which ranked third among the coal producing states. The statistics of production in Pennsylvania, V)y counties, in 1902, with the distribution of the product for consumption, are shown in the following table: Table 4:4. — i^o25 742, 983 9, 247 4, 460 37 31 109,119 49, 310 93, 2.59 30,871 45, 611 21,548 25, 623 53, 688 74, 238 68, 766 55,090 28,346 44,989 26, 667 24, 476 78, 009 7.59,276 6.54. 165 748. 765 332, 550 312, 446 469, 642 239, 697 866, 427 892, 437 Campbell Claiborne 978, 575 815 285 404,855 4.56,436 518, 374 ■ 282,838 1,050,921 Morgan 397 3 ' Includes Bledsoe, Cumberland, Franklin, Hamilton, Overton, Roane, Scott, Sei[uatchie, and White. TiMHtx. — The coal areas of Texas arc included in the Western coal field, which finds its true southern limit in the central part of the state. The Texas areas, however, are separated from the main body of the Western field b\' the Arbuckle mountains, in the Chickasaw and Choc- taw nations of Indian Territory. Extensive beds of ligiiite are found underlying the greater part of the prairie region from the northeastern corner of the state to the Rio (irandc, and an iso- lated basin of bituminous coal occurs in the southwest- ern portion of the state, at Eagle Pass. The jirincipal i)ituminous mines are located along the line of the Texas and Pacific Railway at Weatlierford, in Parker county; atThurber, in Erath count}-; and at Bridgeport, in ^\'is(» county. Ijignitc coal is produced in consideral)le cjuan- tities at Rockdale, in Milam county, and at Calvert, in Robertson county. A considerable amount of bitumi- nous coal is alscj produced at Eagle Pass, in Maverick county, and at Santo Tomas, near Laredo, in Webb county. No report of coal mining in Texas was made at the Tenth Census. The Eleventh Census reported a total production for 1889 of 128,216 short tons, having a total value of $310,620, or an average of $2.66 per ton. The total amount paid in wages during that year was $256,s;-]l. In 1902 the production amounted to 901,912 short tons, valued at $1,177,215, or an average of $1.61 per ton. The wages paid in 19o2 amounted to $991,391. Of the total product in 1902, 696,005 short tons, worth $1,326,155. were Ijituminous coal, and 205,907 short tons, worth $151,090, were of the lignite variety. There were 7 counties in which bituminous coal was produced in 1902 and 9 which produced lignite. The production of lignite in the state during the census year was con- siderably reduced by reason of the large production and use of crude petroleum for fuel.

There is also a somewhat exten- sive area in the southwestern portion of the state, and one in the southern central portion, neithei' of which has l)een developed to any extent on account of its dis- tance from raili'oad transportation. The quality of tlie Utah coal varies from lignite to semibituniinous, Ijufc none of the lignite beds are oper- iited at the present time. The principal production is of bituminous coal, some of which makes a fairly good coke. Of the total production in iyo2, i!30,215 short tons were made into coke in Carbon count}', which is the principal coal producing county in the state, '.:>5.8 per cent of the total output in 19(t2 being mined there. The Tenth Census, co\'ering the ti.scal year ending June 30, 1880, reported the coal production of Utah at 14,748 short tons, valued at $3.3,645. During the cal- endar \'ear 1889 the output, as reported at the Eleventh Census, was 236,651 short tons, valued at $377,456, or an average of $1.59 per ton. In 1902 the production was 1,574,521 short tons, valued at 11,797,454, or an average of $1.14 per ton.

The principal exploration tmd de- velopments have been along the lines of transportation, and even here only in somewhat scattered localities. It is therefore impossible to estimtite with any degree of accuracy the entire productive tirea. The known coal fields are estimated to contain about 2,0iKi squtire miles. The principal field is located in Carbon, Emery, and Uinta counties, and is an extension westward of the Grand River field of Colorado. So far as known, it exists in a comparatively narrow strip running first southwest and then northwest from the Colorado state line, between the 39th and 40th degrees of latitude.

Vlrf/iitia. — There are three distinct coal producing areas in Virginia. The first of these is the Richmond basin, embracing Henrico, Chesterfield, and Goochland counties, and parts of Powhatan and Amelia, in the eastern portion of the state. This- area is placed first. not because of its importance in production at present, but because of the fact that the earliest production of bituminous coal in the United States, as far as known, was obtained from it. The second is an isolated area found in Montgomery and Pulaski counties, in the 700 MINES AND QUARRIES. southwestern portion of the state, where some semi- anthracite is produced, principally for local consump- tion. The third, and by far the most important in point of production and area, is the portion of the great Appalachian region which crosses the southwestern coiner of the state. A portion of this area, in Taze- well count}', contains the famous Pocahontas bed, one of the highest grades of coking and steam coal to be found in the United States. The coal beds in Wise county appear to be a continuation of the ]\Iiddles- boro coal series of Kentucky. There are found within this coal bearing series in Wise county six different coal seams, all of which are of workable thickness. Developments in Wise county began with the construc- tion of the Clinch valley branch of the Norfolk and Western Railway. It is now by far the most impor- tant coal producing county in the state. 76.1 percent of the entire output lieing mined in this district. Although now of little commercial importance, the Richmond basin of Virginia was the first bituminous coal area in the United States to Ite de^'eloped, it having been reported that about fifty-four tbou.sand tons were produced here in 1822. Ten years later, in 1832, the production is reported to have amounted to 132,()(»(J short tons. With the development of other areas more favorably endowed in quality of coal and in ease of mining it, the importance of the Richmond liasin as a source of supply rapidly waned, and by the middle of the last century production had almost entirely ceased. Attempts to reestablish the industiy in this district in recent j'ears have proved expensive and unsuccessful, and although a small amount continues to he mined for restricted local consumption tlie field is practicallv abandoned. ^A'ith the dev(dopnient of the Pocahontas region which followed the construction of the Norfolk and Western Raiiwa\' in 1883, Virginia resumed some importance as a coal producing state. In the census year ending June 30, 18S(>, the production of the state was reported as 43,079 short tons, valued at $y9,802. The first coal shipped from the Pocahontas or Flat Top region (whicli includes McDowell and Mei-ccr counties in West Vir- ginia as well as Tazewell county in Virginia) was from the Virginia side of the line. This shipment was made by the Southwest Virginia Improvement Company from Pocahontas, and amounted to 68,127 short tons. In the calendar year 1889, according to the Eleventh Census, the production of the state was 865,786 short tons, valued at $801,175, all but about 200,000 tons of this product being from the Pocahontas mines in Tazewell county. The development worlv in Wise county began in 1891 with the building of the Clinch valley extension of the Norfolk and Western Railway. Shipments began, from this new field in 1893. In 1902 the production was 3,182,993 short tons, valued at $2,513,595. The average price per ton in 1889 was 93 cents. In 1902 it was 80 cents. The statistics of production, by counties, and the dis- tribution of the product for consumption are shown in the following ta))le: Table 51. — (^jnl production of ]'irg'mia, by coimtiea: ItiOJ. 4 COUNTY.

There arc four principal basins or areas, three <;f them in the western jiart of the statt.', lying in an almost di- rectly north and south line, and oni.' in Kittitas county, near the center. The three former are known as the Northern and Southern Puget Sound coal fields and the Southwestern coal field. The field in Kittitas county, in the central portion of the state, has been designated as the Rosiyn Iwisin, fi-oui the location of some of its principal operations. The Northern Puget Sound field includes the coal mines located in Skagit and Whatcom counties, in the northwestern corner of the state. The Southern Puget Sound coal field includes the coal areas COAL. 701 in King-, Pierce, and Thurston counties, east of tiie cities of Seattle and Taconia. The Southwestern field is a siuall one, lying directly south of Puoet sound. The Roslyu tield, in Kittitas county, is the most im- portant one in point of production, nearly one-half of the entire output of the state being mined in this count}'. Washington is the only one of the Pacific coast states producing true coal, all of the product of Cali- fornia and Oregon being lignite. Some of the Wash- ington coals approach anthracite in character, and some natural coke has been found. A small amount of lignite is also produced in the state. Some of the bituminous coals make a fair grade of coke, and some coke is manufactured in the state each year. Coal mining began in the middle of the last century, in the vicinity of Bellingham bay, in the northwestern part of the then territory of Washington. Operations in this locality were discontinued in 1879 and have not been resumed. Active development of the other coal fields of the state began about 1882, since which time there has been an almost steady grow,th in output. At the Tenth Census the coal production from Washington was 145,015 short tons, valued at $389,046. In 1889, according to the Eleventh Census, the output was 1,030,578 short tons, valued at 12,393,2.38, or an aver- age of $2.32 per ton. Washington's coal production in 1902 was 2,681,214 short tons, valued at $4,.572,295, or an average of $1.71 per ton. The amount paid in wages in 1889 was $1,747,080. The wages paid in 1902 amounted to $3,220,263. In the following table are shown the details of pro- duction, by counties, during 1902, with the distribution of the product for consumption: Table .5.3. — Coal production of Washington, by counties: 1902.

West Virginia. — In the amount of area underlaid by coal West Virginia ranks first among the Elastern states, the coal fields of which belong to the Appalachian s_vstem. Nearly the entire state (17,280 square miles in all) is included in the coal bearing regions. Within the boundaries of this great coal field in AA'est Virginia there are no less than 21 workable coal seams, chief among which is the Pittsljurg bed, which underlies a large portion of southeastern Ohio, southwestern Pennsylvania, and furnishes the famous Big Vein of Maryland's coal areas. This great bed in West Vir- ginia extends from the northern boundaries of the state, where it occurs at the bottom of the upper pro- ductive measures, to the Flat Top or Pocahontas dis- tricts, in the southern portion, where it is found among the lower coal measures. In the northern part of the state the Pittsburg bed attains a thickness of from 14 to 16 feet, and is exceptionally free from impurities in the form of slate partings or sulphur bands. No state in the Union is more favored by nature in the number and extent of its bituminous coal seams and in the variety of high-grade qualities of coal than is West Virginia. The best grades of coking, gas, steam, and domestic coals are produced within its borders. The principal developments in coal production have been along the lines of the three railroad systems cross- ing the state from east to west. These are the Balti- more and Ohio, which cro.sses the northern part of the state from Piedmont to Parkersburg, and the Chesa- peake and Ohio, and the Norfolk and Western, which traverse the southern coal fields, the former from Hinton and the latter from Pocahontas, on the east, to the Ohio river, on the west. The Coal and Coke Railroad, now building from Elkins to Charleston, and the extensions by the Wabash interests, which have secured control of the West Virginia Central and Pittsburg Railway, are expected to develop some of the rich coal lands in 702 MINES AND QUARRIES. the interior of the stnte in the near future. The Deep- water Railroad. ])uildino- from the station of Deepwater, on the Chesapeake and Ohio, to the Norfollv and Western Railway, will reat'h hitherto untouched areas lying' between those railroads. West Virginia ranked third in 19o2 among the eoal producing states, with Pennsylvania first and Illinois second; but with the completion of the railroad exten- sions now in progress and the additional tonnage which will result therefrom, the chances are that it will in a few 3'ears, at most, rank next to Pennsylvania. Coal production in West Virginia began about 186n and was entirely from the Piedmont region, to whicli the Baltimore and Ohio Railroad gave access. Until the completion of the Chesapeake and Ohio and the iSorfolk and ^^'estern railways all of the output was from the northern part of the state. The Tenth Census, covering the hscal year ending June 3t(, 1880, reported the production of coal in West ^'irginia at 1.8i'y.S4:4: short tons, valued at %i2,ttl3,671, or an a\'erage of !?1.10 per ton. In the calendar year 18S'.t, according to the Eleventh Census, the production was (i,:231,S80 short tons, valued at $5,()86.5S4:, or an average of 82 cents per ton. In 1902 the production amounted to 24.570,826 short tons, valued at S24, 7-18. 658. or an average of %>1.()1 per ton. A relatively small amount of coal is consumed at iron works in the vicinitj' of Wheeling, at salt works along the Ohio river, and in some unimportant manufacturing establishments throughout the state. But with these exceptions all of the product, save that foi- household consumption, is shi]5ped out of the state or is used by the railroads engaged in its transportation. Large quantities are shipped from the (Cistern paits of the state to the seaports of Baltimore, Norfolk, and New- port News, and from these ports to coastwise and foreign markets, and from the western fields by rail and river to interior and gulf points. The production by counties in 1902, with the distri- bution of the product for consumption, is shown in the following table: Table 55. — Coal production of West Virginia, by counties: 190S. Total.

COAL. 703 Wijoming. — The coal fields of Wyoming are included among- those of the Rocky mountain area, althoiigli most of the productive areas are in the plains region, east of the mountain ranges. There are no less than fourteen different and rather widely separated fields distributed throughout the state. These different areas are known as (1) the Black Hills held, located in Con- verse and Weston counties, in the northeastern part of the state; (2) the Casper ffeld, a small bituminous area in the eastern part of Natrona county; (3) the Carbon field, and {A) the lianna field, both in Carbon county; (5) the Rawlins field, in the western part of Carbon and eastern part of Sweetwater county; ((!) the Rock Springs field, and (7) the Plenrys Fork field, both in Sweetwater count}-; (8) the Hams Fork, (9) the Almy, and (10) the Sublette fields in Fremont county; (i:-!) the Bighorn, and (14) the Powder river fields in Bighorn county, in the north-central part of the state. The printdpal developments have been in the several fields of Carbon, Sweetwater, and Uinta counties, which are traversed b_v the Union Pacific Railroad, and. to a less extent, in Converse, Natrona, Sheridan, and Weston counties, reached by a branch of the Burling- ton system. Sweetwater and Uinta counties together produced 72 per cent of the state's total output in 1902. Coal mining in what is now the state of Wyoming began in 1865 with a product of 80') tons, so far as re- corded. In 1868 the production of the then territory amounted to 6,92.5 short tons, and in lS7(t the output was Table 58.— SUMMARY BY COUNTIES HAVIX(i 105,295 short tons. The Tenth Census reported a pro- duction of 5H9,595 shoit tons, valued at|l, 080,451, or an average of fl.s8 per ton. According to the Eleventh Census, the production in the calendar year 1889 was 1,388,947 short tons, valued at $1,74S,617, or $1.26 per ton. In 1902 the output was 4,429,491 short tons, worth $5,236,33^), an average of $1.18 per ton. At the Tenth Census the total wages paid were $579,566; at the Elev- enth Census the wages paid amounted to $1,553,947, and in 1902 they were $3,207,545.

It has been customary to con- sider as bituminous coal all varieties from lignite to ,semi- anthracite. The different varieties merge into each other by such indistinguishable gradations that no al)- solute line of demarcation is possible. The general term of "bituminous" coal as used in this report in- cludes, therefore, lignite or brown coal, cannel, block, splint, semibituminous, semianthracite, and, as stated. the small anthracite product of Colorado and New Mexico. The bituminous areas have been divided by the United States Geological Survej' into the following sub- divisions: (1) Triassic, (2) Appalachian, (3) Northern, (4) Central, (5) Western, (6) Rocky Mountain, and (7) Pacific Coast. They are described briefly, as follows: 1. The Triassic field embraces the coal beds of the Triassic or New Red Sand.stone formation, and is worked in the counties of Chesterfield and Henrico in Virginia (generally known as the Richmond basin), and 704 MINES AND QUARRIES. the coal along the Deep aud Dau river.s in Chatham count}', N. C. The earliest production of hituniiuous coal in the United States was made in the Richmond basin of Virginia. The tirst production from the small area in North Carolina was reported in the census j'ear 1889. Only one commercial mine has been opened in the region and the production has not reached any large proportions during the fourteen years that the mine has been operated. 2. The Appalachian tield, which extends from the northern part of Pennsylvania on the north to the cen- tral part of Alaliama on the south, follows in a south- west direction the Appalachian mountain system. Its entire length is a little over 900 miles and ranges in width from 30 to 180 miles. The area of the coal fields of the Appalachian region is estimated at 70,807 miles, the productive area covering nearly all of western Pennsylvania, the eastern part of Ohio, the western part of Maryland, the southwestern corner of Virginia, nearly all of West Virginia, the eastern part of Ken- tucky, the east-central part of Tennessee, the north- western corner of Georgia, and nearly all of northern Alabama. All of the coals produced in this region are of a bitu- minous or semi bituminous variety, except for a small amount of semianthracite mined in Montgomeiy county, in the southwestern partof Virginia. Within this region is found bituminous coal of nearly every variety of chemical composition and physical structure. Within its boundaries are found the famous Connel]s\-ille coking coal, in Fa3'ette and Westmoreland counties. Pa. : the Clearfield and Pittsburg steam coals; the Youghiogheny river gas coals; the famous smithing coals of Blossburg, Pa., and Cumberland, Md.; the gas and coke producing coals of the upper Potomac and upper IMonongahela rivers; the Massillon and Hocking coals of Ohio, noted for their domestic qualities and for their \-alue in the iron reducing furnaces; the coking coals of the Poca- hontas Flat Top region; the steaui, gas, coking, and domestic coal of the New and Kanawha river series; the Jellico coals of southeastern Kentucky and north- eastern Tennessee; and the excellent coking and steam coals of southeastern Tennessee, Alabama, and nortli- western Georgia. The production of bituminous coal in the Appalachian region during 1902 was 173,274,801 short tons. In 1889, at the taking of the Eleventh Census, this region produced 62,972,222 short tons, and in 1880, at the tak- ing of the Tenth Census, it produced 29,834,022 short tons, showing an inci-ease in 1902 of 110,302,639 tons over 1889 and of 143,440,239 tons over 1880. 3. The Northern coal field lies altogether in the lowei' peninsula of Michigan, between Lake Michigan and Lake Huron, extending from Jackson county on the south to Roscommon covuitv on the north, and frouj Tuscola county on the east to Kent county on the west. It embraces an area of approximately 7,.500 square miles. It is the only known coal field lying in the drain- age basin of the St. Lawrence river within the limits of the United States. The northeastern edge of the field is penetrated by Saginaw bay, through which, with the Saginaw river, it is given easy access to Lake Huron and thence to the ports of the Great Lakes. Although coal was produced in this region as early as 183.5, it is only within the last few years that the production has amounted to any great importance. In 1880 the Northern coal field produced 100,800 short tons; in 1889 the output had fallen to 67,431 tons. The active development of the region really began in 1897 and by 1901 the production had amounted to 1,241,241 short tons. Labor troubles in the census year of 1902 reduced the output to 964,718 short tons. 4. The Central coal field includes all the coal produc- ing areas of Indiana, Illinois, and western Kentucky. It extends from the northern part of Illinois (most of the central and southern parts of the state being under- lain by workable coal seams) to the central part of western Kentucky. The field is estimated to contain an area of 42,90() square miles in Illinois. 9,300 square miles in Indiana, and 5,8(i0 square miles in Kentucky, making a total for the entire field of 58,000 square miles. The coal field underlies SO counties in Illinois, 26 in Indiana, and 20 in Kentucky, although coal is not at present mined in all of the counties in any of the three states. It is from the Indiana portion of this field that most of the well-known " block" domestic ccwil is produced. In the Kentucky portion of the field the coal grades into a quality suitable for coking purposes, and consid- erable (juantities of coke are produced in this portion of the field, although practically no coke is made in either Illinois or Indiana. The Central coal field, while fourth in size among the coal fields of the United States, is second in pro- ducing importanc(\ Illinois, which contains nearly three-fourths of the entire area, was second in 1902 among the coal producing states. The production from this entire field in 1902 was 46,133,024 short tons, an increase of a litth^ over 180 per cent as compared with 1889, when the production was Ki, 240. 314 tons, and of 466 per cent as compared with 1880, when the produc- tion Avas 8.150,195 tons. 5. The Western coal field forms a practically I'ontin- uous belt of coal measure rocks from northern Iowa in a southwesterly direction through central Texas to the Rio Grande, a distance of 880 miles, and underlving a total of 94,076 square miles. It includes the coal l)earing areas of Iowa, Missouri, Nel)raska. Kansas, Indian Territory. Arkansas, and Texas. Within its boundaries are found all the Aarieties in- COAL. 70 JD eluded under the general head of bituminous coal, from lignite to somianthracite, imnion.se areas in Texas being underlain b_v lignite, while semianthracite is found in Indian Territory and Arkansas. Coking coals are prf)- dueed in Indian Territory, cannel coal is produced in Missouri, and l)lock coal is mined in Iowa. Most of the coal produced is of the Av}% noncoking variety of bituminous coal. The production in the census j^ear of 19()-J amounted to 20,T^7,4:!t5 short tons, as compared with l(),(»36,;-5.56 short tons in ISyf* and 8,212.787 short tons in ISSO. The development in this region during the last twenty j'ears has been of extraordinary rapidity. t). The Rocky Mountain coal field includes the pro- ductive areas in the states lying along the Rocky moun- tain range and also those of North Dakota, although the coal tields of the latter state do not lie within the Rocky mountain s\'stem. The states from which coal has been produced in this held are Colorado, Idaho, Mon- tana, Nevada, North Dakota, Utah, and Wvoming, and the territory of New Mexico. Idaho and Nevada have produced insignificant amounts for purely local consumption. South Dakota has produced an insignifi- cant amount of lignite, but none in the last few j'ears. The known areas cover a little over one hundred thousand square miles of territory. The production from the entire region in 1902 was lb,14:9,54:5 short tons, as compared with 5,U4S,-J:13short tons in 1889 and 1,067,314 short tons in 1880. 7. The Pacitic Coast field embraces the coal produc- 30223—04 45 ing areas in the 3 states borrlering on the Pacific ocean — California, Oregon, and Washington, 'i'lie coals are all of the Tertiary age and are hirgely lignitic in character. The only t)ituminous coal produced in the Pacihc coast region is mined in "Washington, all of the product from California and Oregon being lignite. Some of the bituminous coals in Washington possess good coking (juaiities, and some coke is made in the state each j-ear. The hrst production in this region was, so far as kiKMvn, in California in 18()1. The Hrst coal mined in Washington was, so far as known, produced in l88n, and it was not until 188.5 that any coal was reported to have been produced in Oregon. All of the growth in the last two decades has Ijeen in the Washington coal fields. The production in California has decreased since 18S0. The production of Oregon in 1902 was about the same as in 1889, and 30 per cent more than in 1885. The production of ^A'ashington, however, has increased from 115,015 short tons in 18S 185 234 18,208 78 5, 755 350 850, 697 130 $193,513 $92, 450 8101, 063 $370, 268 986, 201 81,942,361 8,603 153 5, 781 $.58, 614 387 $1,9.55,982 8877, 8,84 81,078,098 82,441,760 10, 779, 20S $22,534,716 65, 925 991 64,279 4 121 21 1,,525 40 2, 591 816,483 68 8690, 083 8332, 997 8357, 086 81,172,483 2, ,878, 615 $5, 602, 584 39, 774 373 37, 624 $17, 408 .52 Miscellaneous expenses: $:«0, 244 Royalties and rent of mine and mining plant Reiit of offices, taxes, insurance, interest, and other $204, 737 8185, ,507 $579, 172 Product; 1,739, .598 $3,419,733 Power owned: 22, 456 Engines- Steam- 222 Horsepower 21 , 574 Gas or gasoline- Other power- Number Horsepower Electric motors owned— 30 2,822 60 4,6,86 29 2, 364 350 ,54 2, 1.50 3 150 CO 6, 207 3 .520 9 818 3 130 "■ COAL. 709 Table GO.— COAL, BITUMINOUS— DETAILED SUMJIARY, BY STATES AND TERRITORIES; 1902.

By K. H. OijpiiANT. The only I'ensus statistics for tlio production of crude petroleum comparable with those of 19(.)'i ai'c the sta- tistics for ISTO and 1889. No census of the industry was taken in 1860, the year following- the drilling- of Drake's well, and the census of 1880 was chieHy for re- Hned petroleum, although some data were given for the crude. In Table 1, which is a comparative summary from 1860 to 190^, the production shown for 186<» is the estimate published l)y the United States Geological Survey, and the hgures for 188n are selections from tabulations in the census report. However defective the basis of comparison, the table is sufficient to indi- cate the progress made from one period to another in the rise of this important industry.

The Census figures repre- sent the petroleum produced. The statistics showing the production of petroleum in the United States during the decade between the census years 1889 and 1902 indicate a very remarkable increase in the quantity and value of this important natural product. The number of barrels produced in 1889 was 35,163,513, valued at *:^6,963,310. The num- ber of barrels produced in I'.tOii was 89,275,302, valued 30-223— 04 4B at $71,397,739, which shows an increase of 153.9 Y>er cent in quantity and 164.8 per cent in value. Tlie average increase in (juantity for eachof the twelve veai's between the dates named was 12.8 per cent andinvidue 13.7 per cent. The conditions that brought aljout this increase were varied and extensive, the most conspicu- ous of which was the opening up of several large pools in noi'thwestern Pennsylvania during 1890 and 1891, followed liy the development of the McDonald pool near Pittsburg, which reached its zenith in 1891, giving to Pennsylvania in that year the greatest production in its record. In Ohio, from its two fields, there has been a gradual increase, the production reaching its height in 1896, with a slight decline to the close of 1902. In AVest Virginia, from 1890 to 19()0, there was a remarkable increase in the production, the greatest output being in the latter j-ear; this has since been followed by a gradual decline. In Indiana there have been almost continual gains since the lieginning of 1890 to the close of 1902. In California, during the period beginning with 1894 and ending with 1902, there has been a remarkable increase in production, this being most marked from the begin- ning of 1900 up to the close of 1902. Since the year 1898 the production in Texas has been increasing at a wonderful rate; the gain in 1902 compared with 1901 was the greatest on record. A decided increase was also shown in Kansas. While the combined output of the older fields in the northeastern ]5ortion of the United States showed onlv a very slight decline, the fields of the Southwest and West developed an extraordinar}' increase in new pro- duction, although this production was of a quality inferior to that of the older fields and was marketed at a less value. The total number of all wells at the t-lose of 1902, which includes the dry holes and those abandoned, was 118.671; of this number 108,601 were productive -\vells. llW/.v mid ttnih/f/r. — The total number of wells drilled in 19(12, both dry holes and productive, the number of flowing and pumping wells, the number of wells (721) 722 MINES AND QUARRIES. operated, the number of wells that produced petro- I tanks at the wells and their capacity for receiving leuni and the number abandoned, and the number of ! the output are shown in the following table: Table 2.— RECORD OF AVELL8 AND TANKAGE, BY STATES AND TERRITORIES: 1902.

In the entire United States there were 15,506 wells drilled in 190:^; of this number 3,158 were dry hole.s — that is. wells W'hich did not produce petroleum in suffi- cient cjuantity to justif}' pumping them or were totally destitute of petroleum. The number of producing wells drilled in 1902 was, therefore, 12,348. There were 69-1 flowing wells producing petroleum and 107,950 wells that were pumped, making a total of 10,S,64:-± pro- ducing wells in the United States in'l9(>2. The great- est number of flowing wells was in West Virginia, where they numbered 500. Flowing wells do not usually continue to flow for long periods, and are found only in comparatively new territory, where the pressure of natural gas still remains in the rock. Wells that are pumped are usually oper- ated by sucker rods — wooden rods with iron sockets reaching down inside a 2-inch pipe or tubing to a work- ing barrel at the bottom containing ^-alves, the packing- being made by leather cups. The motion is from lo to 18 inches, 20 to 60 strokes per minute. The depth of wells which jiroduce petraleum varies from 250 to 3,300 feet; the latter depth is attained only in West Virginia. Of the total producing wells 7n.S poj- cent are located in the states of Ohio and Pennsvlvania, the former state leading the ktter bj^ 1,250 wells. The number of producing wells in New York w'as 8,178 and in Indiana 8,224. California conies next with 2.57-1 pro- ducing wells, 35 of which are flowing. The number of wells in the United States abandoned during the vear was 6,869, wdiich is more than half of the productive wells drilled in 1902. The greatest number of aban- doned wells in 1902 was in Ohio, where the number reached 2,533. The number of abandoned wells in Pennsylvania was 1,879; in West Virginia, 1,322; and in Indiana, 772. The tanks \-ary in capacity from 5 to 1,200 l)arrels, and are connected with the pipe line system by pipes. Each tank is usually measured and numbered by the pipe line company and the number of barrels to the inch noted. A \-alve that is attached to the bottom of the tank and the lead line is locked by the pipe line company and is only opened when the numlierof inches of petroleum in the tank is measured by the ganger, and it is closed liy him at the end of the run. < 'iijHftil Kti)ch iif niciirjxiniti il ri;, 514 :^-I'i,s,yU4,-18y I ;i-'s,(.i:;:i, :;o-l , $101, Kin, si;vi :?3'Ji.(i:-!r,,9iL: ■ 2, 117 J4,743 120 620 2, 130, 951 », 149, 661 ¥27,373 162 11,775 UDII 9l,!i9;; ■6, 7 1 ;i, 256 S297.:l:::: California.

Althouu'h Ohio, A\'e,st Virginia, Texas, and California produced more petroleum, they employed fewer wage-earners, because more of their wells were large producers. Pennsylvania employed 32 per cent of the wage-earners and producetl only 13.5 per cent of the entire product, the wells with one exception being pumping wells. On the otlier hand, Texas em- ployed only 4.1 per cent of tiie wage-earners, although producing 2i).l per cent of the petroleum; and Cali- fornia with ().3 per cent of the wage-earners yielded 15.7 per cent of the petr(_)leum. There was very little fluctuation in the number employed, taken as a whole. The a\erage number of wage earners by occupations at specified daily rates of pay is shown in the following- table: Table 5. — Average number of wage-earners at sjiecified daibj rates of jiaij, 1)1/ occupations: 1902.

Only a))out eight- tenths of 1 per cent received less than $].5(tperdav. Of the 12,951 engineers, 76.2 per cent received between $2.25 and $2.49 per day, and only 1.4 per cent received less than i?1.75 per day. Of those rated as mechanics, including blacksmiths, carpenters, and others of like occupation, 63.7 per cent received from $1.5() to $2.74 per day and 19.1 per cent from $2.75 to $3.24. Abcjut four-tenths of 1 per cent of this class of wage-earners received less than $1.5(.» per day. Nearly 84 per cent of "all other wage-earners" received from |1.50 to $2.74 per day. Contract 'inoji'. — TIk^ amount paid for contract work was $12,956,631, or 44.4 per cent of the total amount paid for salaries, wages, and contract work. Nearly all the building of rigs, drilling of n(>w wells, torpedoing and cleaning out was done by contract work, tlie cost of w^hicb also includes the value oi material furnished and a profit to the contractor. Thei-e are numerous instances where the owners of wells contracted with individuals for the work necessary to pump and care for a cluster of wells, dividing thepipe line runs -pro rata. The entire number thtis employed is estimated to be 12,S0(>. A concise statement covering the entire petroleum producing fields is difficult to secure. The drilling of a well requires from ten days to seven weeks, and. when the work is completed, the crew is removed by the contractor usually to some distant location. A crew is temporarily employed to clean out a well after it has been torpedoed. In torpedoing wells, building tanks, connecting pipe lines, and in other matters of labor and materials furnished which ;ire paid foi' in the lump, a similar condition of aflairs existed, the work- men going from well to well or from disti'ict to district. Thus it is that no detailed account can be secured show- ing what part of the disbursements for this kind of work went to laljor under the head of "cost of contract work"" and what to "cost of supplies and materials." SiiJ'/ihc'S. iiiKti'milx^ and iiiJui'ellrnirOus i/.rjiciixes. — Under supplies and materials are included casing, tubing, pipe, engines, l)oilers, tanks, etc., and renewals. Under miscellaneous expenses are included rent of offices, taxes, insurance, etc., and royalties and rent of wells and plants. The entire expense reported under the above headings for the year 19(.)2 was $33,593,238. Mechaiiiral piiirer. — For the producing wells a total of 91(»,(i77 horsepower was reported, of which !»07,854 horsepower was owned by the operators and 2,223 horsepower was rented. Of the power owned 666,177 hor.sepower was furnished by 41,797 steam en- gines, 240,5(.)5 by 12,6tt6 gas or gasoline engines, and 1,172 horsepower by 37 other prime motors. In addi- tion, 2 electric motors with a capacity of 25 horsepower were rept)rted. The steam engines averaged approxi- mately 16 horsepower, and the gas or ga.soline engines 19 horsepowei-. The rented power consisted of 125 electric and 2,098 horsepower of other kinds. The electric pow(>r, both owned and rented, was reported from California. Over 54 per cent of the horsepower was employed in Pennsylvania. Proihwfidii. — The produt^tion of crude petroleum in the United States in 1902 was 89,275,302 barrels—' gi-eater than ever before and nearly equal to that of Russia and all the other petroleum producing countries of the world combined. This was the product of 108,644 wells, an average of 822 barrels per well, or 2.14 bairels ])er well per day. The quantity and value of the crude petroleum produced in the United States in 1902 are given bv slates and territories, arrano-ed in the order of their production, with percentages of the whole, in the following table PETROLEUM.

The home consumption has been growing of late, as well as the production of crude petroleum of second qualit}'. As before noted, the total exports, for the first time, exceeded one billion gallons ill IKol. There was a slight decline in 1902. yet the amount for the year was still over one billion gallon,s. The exports of lubricating and paraffin prod- ucts have for a number of j^ears shown a steady increase.

' ' ^ Includes the production of Michigan. ' Includes production of Michigan and small production in Oklabonui. ^Does not include ,508,386 barrels produced, but not marketed. Since the year 1888, when the entire production was only 27,612,025 barrels of crude petroleum, there has been on the whole a gradual increase. The year IS'.U, when the production reached Si, 292, 655 barrels, had the largest output up to that date, owing chiefly to the increase in Penn.sylvania petroleum, caused })y the ojDening up of some wonderfully prolific territory at McDonald, in Allegheny and Washington counties. From 1891 to 1893 there was it considerable decline in the production, tlie latter year having the smallest out- put since 1891. v^fter 1894 there was an increase, and the year 1896 showed a larger production than any year up to that date. The figures were not surpassed until 1900, when the production was 63,620,529 l)arrels. The year 1901 sliowed substantial gains tiver 19()0, while that of 1902 was nearly 20,000,000 barrels greater than 1901 . This increase was due chiefly to the increased production of Texas, California, and Louisiana. The grade of the oil . however, was generally inferior to that of older tields. The production of the high grades of petroleum pro- duced in the Appalachian, Lima-Indiana, Kansas, Cor- sicana, and the Colorado flelds remained about the same as in the previous 3'ear. From the output of these flelds a superior grade of reflned products is manufactured. The poorer grades of petroleum pro- duced in Texas, Louisiana, and California were mar- keted in 1902, principally for fuel, at much reduced values, although the average price received for the better grades increased about i cents per barrel over the average price in 1901. It will be seen in Table 13 that the production of crude petroleum in tli(^ United States from the beginning of the PETROLEUM. 781 petroleum industry in 1859 to tlie end of 1902 was l,lt;5,- 290,218 barrels. Allowing 5.6 cubic feet for the cubical contents of a barrel of 13 gallons, this quantity would occupy 6,525,625,389 cubic feet and would require a cube 1,869 feet on each side to contain it. It would fill a tank the base of which was 1 mile square to a height of 231 feet. This quantity -would lill 38,S13 ordinary tanks containing 3(»,(i00 ban-els; allowing HO feet f(U- their diameter, if the}' were placed side by side the}' would reach a distance of over 662 niiles. Again if 2^ feet be taken as the height of a barrel of 12 gallons and if there were sufficient l^arrels to contain this amount of crude petroleiuu and the barrels were laid so that their heads would touch, they \Fould encircle the globe 2.27 times. Allowing 3i barrels to equal the fuel value of a ton of the average coal, the amount repre- sents a fuel value of 332,910.071 tons of- coal. There were 301,590,139 tons of coal produced in the United States in the year 1902; the fuel value of the petroleuiu produced in 1902 would equal that of 25,507,229 tons of coal. The value of the petroleum produced since 1859 to the close of 1902 was $1,166,885,363; the aver- age price was therefore $1 .Oi til per barrel. The amount invested in wells and fixtures at the end of 1902 is esti- mated at $290,000,000. The quantity and value of the crude petroleum pro- duced in the United States for each year since 1859 is shown in Table 11.

It will be seen from the preceding tallies that for the year 19i)2 the combined runs for the Appalachian and Lima-Indiana fields were 51,?>s8,553 liarrels, which amount does not vary greatly from the average for the past eight j^ears, though a slight decline was recorded in 1902 as compared with 19nl. There are some few deliveries to refineries direct from the field and some petroleum loaded in tank cars that are not included in the pipe line reports. The shipments which represent the deliveries from both, these fields to the refineri(\s and other consumers were quite large in 1902, amounting to 57,283,l('i(i bar- rels, an increase (.if 3,040,919 barrels over those of 1901. As the shipments were larger tlian the production, the increase was made up from the stocks which ha-d ))een accumulated by the pipe line comjianies. The Appalachian and Lima-Indiana stocks on hand at the close of 1902 amounted to 23, (lis, 050 barrels, show- ing a decrease for these fields of 4:,34:7,748 barrels as compared with the amount at the close of 1901. These stocks are stored in large iron tanks iit a numlicr of localities, generally near the pumping stations of the main pipe lines. The stocks in the fields are held principally by the large pipe line companies, who have, in nearly all cases, purchased the crude petroleum. There is also a vary- ing amount of stock held b_v the original producers at their wells. In the states of Te.xas and California, liesides the stock in the hands of the producers and refiners, there are a number of individuals, companies, and railroads who own their tankage. The estimated stock in these iind other states and territories, as well as in the Appalachian and Lima-Indiana fields, is shown in the following table: Table 2.5. — S/oi'kx of petroleum held in the several fielels, staten, and lerrltories at tlie close of 1902. 1901, aial 1900.

In that year there were 16,4r57,08!:> barrels of what is known as Pennsylvania oil, held in tanks, principally in Penn- sylvania, and smaller amounts in West Vii'o-inia and Ohio, as compared with 5,741.t'iL'4 barrels held at the close of 1902. In the Lima-Indiana tield there were 22,103,705 barrels, principally in Ohio, making a total stock for the two tields of 38, 5ti(.», 791: barrels in ISDl, as compared with 23,048,050 barrels at the close of 1902. Of the latter amount 5,741,(324 barrels were Appa- lachian petroleum and l7,3()<3.42(i barrels Lima-Indiana petroleum. The success in refining the petroleum from the Lima-Indiana field has greatly increased the pro- duction of the higher grade of illuminating petroleum and enabled the refiners to supply their home consum- ers and furnish an increasing quantity for the export trade.

This is owing to the fact that the production of some districts furnishes a larger percentage of illumi- nating oil and of by-products. Petroleum that has remained in tanks at the wells for a long period loses a percentage of its illuminating properties and is worth less than what is known as fresh oil, or petroleum recently' produced at the wells. The great volume of trade is controlled by the prices under the name of Pennsylvania oil, which includes nearly all the oil sold in New York, nearly all of that sold in Pennsylvania and West Virginia, and a large proportion of the ordinar3' Appalachian petroleum sold in Ohio. In the following table are given the avei'age monthly prices during 19(.»1 and 1902 of crude petroleum pro- duced in the various districts of the Appalachian oil regions in which special prit'es are paid. It is consid- ered that the bulk of the crude petroleum is sold at prices slightly greater than the average price per month.

Tliis division is made owing to the lighter gra\'ity of North Lima petroleum and the larger percentage of the more valualiie products secured from it. The pi-othiction of the Indiana tield is of the same grade as the South Lima petroleum and commands the same price. In the following table there is shown the fluctuations in prices for the various grades of Lima oil in I'.HW. The dates are those on which changes in prices were made.

Still farther inland there aiv, seams of bituminous coal from '^ to 8 feet in thickness and of superior quality. This section is generally iet in depth and vary in production from 2 to 25 l)arrels per day. The petroleum is black, with a gravity vary- iug from 15 -^ to 17"-' Baume. Recently a pipe line has been constructed connecting the Whittier pool with Los Angeles. There is also a producing field at Xewhall, at the head of the Santa Clara canyon, in this county, which yields a superior grade of petroleum. Some very good wells have been secured in Orange county at FuUerton, at Brea canyon, and elsewhere in the vicinity. A few of these wdls were drilled to a depth of 2,100 feet, and the production at first reached as nmcli as l,oo() barrels per day. The AVhittier pool, in Los Angeles county, lies just northwest of the Ful- lerton ]iool. These pools produce a petroleum of high grade, which is in demand for refining and for which a high price is paid. The Coalinga field, on the east flaidv of the Coast Range in Fresno county, was opened up in 1897. Most of the petroleum produced in this field ranges from 22 to 38- Baume, although there is some petroleum as heavy as 11 Ba\une. In the northeastern portion of the field the grax'ity of the production ranges from 20- to 28'^ Baume. It is suitable for refining and is in demand as an enricher of manufactiu'ed gas. Ventura county continued to pi'oduce petroleum in a compai'atively small way along the Santa Clara \alley to the south. There is consichn'able \ariation in the char- acter and gravity of the ])etroleum produced. A very light petroleum of about 35 Baume is found in Pico canyon near the Los Angeles county line. Opei'ations were active in Santa Barbara county in 1902. A large production was secured on Los Alamos creek, which locality has been operated successfully for several years. A will with a capacity of 200 barrels was foiuid near Lompoc. Summerlanil district is in this county, bid was not acti\ely operatinl during lit()2> and has declined in ])roduction. The problem of transportation from the California oil fields has not been fully sohcd. The oil develop- ment of the state has been much retarded by the lack of facilities for getting the oil to market. Most of the production is within reach of the railways by short pipe lines, but there has been a deficiency of cars to meet the demands, and consumers ha\ c hesitated to PETROLEUM. 739 adopt t)il as fuel l)ccaiiso of the uncertainty of getting- a supply when needed. An 8-inch pipe line is being constructed from the Kern river district to a refinery at Point Richmond, on San Francisco bay, which eventually will have branches to the important oil producing localities in the San Joaquin valley. A branch to th(^, Coalinga lield is now in process of construction. The main pipe line will be 278 miles in length with Id pumping sta- tions, and the oil will be heated to permit its easy pumping. The completion and operation of this pipe line are matters of very great importance to the indus- try of the state. A railway, chietiy for the transpoi'- tation of crude oil, is projected from the Sunset district to tide water at Port Harford, but at the close of 1902 little progress had been made toward its construction. Tankage supplj^ stations have been established in the Hawaiian Islands, and large tank steamers are now^ running to the islands from San Francisco and southern California ports. Large supply stations are also being- installed at various points along the coast as far north as Washington, and these will be supplied by the rail- way's or by ocean transit as will be most convenient. The chief use of California petroleum is as fuel, and the market for it was gradually extended during 1902. The railway's of the state are adopting it as rapidly as possible. The Southern Pacific Railway has estab- lished a large amount of tankage on its line at ditferent points. Both the Southern Pacific and the Atchison, Topeka and Santa Fe railways are the owners of tracts of oil lands from which part of their supply is drawn. The use of the heavy oils for improving roads is in- creasing. The price of California oil during 1902 was low, but some advance took place toward the close of the year. Large contracts for the deliver}- of oil at the wells for a period of five years, however, were made at the rate of 20 cents a barrel. This price applied to the heavier oils of the Kern river and McKittrick districts. Lighter oil produced in the southern part of the state com- manded as high as $1.00 and $1.20 a barrel Avhere the quality was such as to permit refining- into illuminating- oils. During the j-ear the nunil)er of refineries in the state increased from 11 to 33. Most of them were small and designed more particularly for the production of asphalt from the heavy oils, which yield from iO to 50 per cent of this material. The distillates obtained in this way are used largelj^ for domestic fuel, for gas making purposes, and, to a slight extent, for spraying- fruit trees. The largest installation for refining Cali- fornia oils is at Point Richmond, near San Francisco. In the following table is shown the production of petro- leum in California by counties for the vears 1897 to 1902: Table 32. — Froilmiida nf tnule juirdlcum in i'lilifor-iiid, Inj counties: 18;n tu 1902.

The production of the Boulder pool was only ll,S<.tO barrels. Its quality was superior to any other petroleum found west of the Mississippi river, and its gravity when fresh was -12. .5^ Baume. The new Boulder field was partially ojjened up in 1901 by the McKenzie well, wdiich found petroleum at a depth of 2,720 feet and was the cause of the drilling of a num- ber of deep wells in this new field. These, however, produced only a limited quantity of high-grade petro- leum. There were 48 wells drilled in the state, 28 of which were dry. The total number of producing wells was 77, and the number abandoned during the year, 6. There were 60 tanks at wells, with a combined capacity of 41,579 barrels. An important deep well was drilled in the old Flor- ence field south of the city, which at a depth of 3,650 feet found a pay streak never before reached by any of the wells in that field. The strata in which the petro- leum is found stored in this field, and also in the Boulder field, are considered to belong to the Fort Pierce group of the Montana Cretaceous. The Florence field fur- nished nearly 98 per cent of the .state's production in 1902. The petroleum is of a dark green color, with a gravity of from 31"^ to 32-^ Baume, and in refining gives a fair yield of the more valuable products. The production in 1902 sold for $1:8'1:,683, an average of 11.22 per barrel being secured. IlJinoiH. — The production of petroleum in this state, although extending over a period of nearh' fifteen vears, has been insignificant. Even the small production se- cured seems to be growing smaller. There is a prolia- bility, however, that the state may yet produce suffi- cient petroleum to become of significance as a producer. Nearly all of the petroleum comes from Litchfield, Montgomery county, and is used locally for lubricating f4() IlIINES AND QUAPiRIES. purposes. Its gTavity is 22- Ruunie. The wells are from 640 to GTU feet in depth. There is a siiiail pro- duction from shallow wells at ^^''asllin,o•ton, Tazewell eounty. It tinds a sale as luhrieatini;- petroleum, the production, valued at $5 per harrel. amounting to $1,000. In October, 1901, petrolemu was reported to have been found in small quantities (i miles west of Canton, Ful- ton eounty, and also in the town of Herscher, Kankakee eounty. The production of the state since iss!) has been as follows: Table 33.— Prodnrfim, „f prlrolnu,, in IIIIihks: ISdV to 190J.

There are probabl}' 28 liarrels of salt water pumped for each barrel of petroleum produced. A number of wells that were formerly natural gas producers have l)een drilled deeper and have found petroleum in paying quantities. It is a held of eas}' access, and is abundantly supplied with facilities for transporting supplies, as well as with pipe lines, for marketing the petroleum. The production in 1902 was 7,480,896 barrels of crude petroleum, \-alueil at $6,526,622. This is a gain of 1,72.3.810 barrels in quan- tity, and $1,703,796 in value over 1901, the increase amounting to 29.9 per cent in quantity and 35. y per cent in value. Indiana was the only state in the north- eastern portion of the United Stat<'s that ga\"e an in- creased production in 1902. The most active operations during r.J02 were in (iraiit county, one-third of the new wells in the state being- drilled in this county, adding a considerable new and rich territory to the known productive area of the state. The section near Marion once famous for lai'ge natui'al gas wells is now important as a petroleum pi-oducing region. The exhaustion of the gas enabled operators to drill the wells deeper, and results have been i-emai'k- ably successful. The counties of Adams, lilackford, Delaware, Huntington, Jay, Madison, Randolph , and Wells were all more or less conspicuous for new widls and increased production during the year. In addition to the production from the regular limestone sti'ata of the Ti'ent(.)n hoi'izon, there are a niunberof small pools in newer horizons that lia\'e pi'oducecl small (|uautities of petroleum, ln.it no vei'y successful wells were discov- ered, altliough there was a small ])i'oduction in Dubois, Jasper, Martin, ami ^'igauni(', and is said to Ije somewhat superi(U- to that produced in the Beau- mont and Sour Lake pools. About 12 miles -west of Jennings the Welsh pool is located. There arc indications that a considerable area of productive territory would be found in this locality. The same difficulty presented by beds of loose sand asso- ciated with petroleum and natural gas is encountered in this tield. The Jennings and Welsh tields had been con- ' nected by pipe line with both railroad and tide water transportation, and a large amount of the product has been marketed as fuel petroleum. ^rixmniri. — There has lieeii a small production of petroleum in this state since Ls8'.i, the product being secured from a shalltiw w(dl located in Bates county, near th(? town of jMerwin. It is heavy and dark in color, and flnds sale as a luliricating petroleum. During the year VM'l .seven shallow wells, from Hlo to 4!t0 feet in depth, were drilled at Belton. in Cass county, and a small quantity of lubricating ])etroleum was secured. The production in this field, although insignificant in 1902, showed an increase over the previous year. ■—- 2JirIi/ petroleum indications are reported. Three wells were recently completed in Carl)on county, in which, however, only a V(_u-y small (piantity of petroleum -was secured. Nciyidii. — Although several wells were drilled in this ,stat(> during 1901 and lt»o2 no production of petroleum was secured. Several wells drilled in the vicinitv of 742 MINES AND QUARRIES. Elko encountered sand and slualcs similar to tliose in which petroleum is found in otiier localities, but no petroleum was developed. Nevj JA^./vVv'.— There are indications of petroleum md asphaltum deposits scattered over a large area in New Mexico, but nothing- yet has been de\-eloped in tlie way of productive wells. There are a considerable number of natural showings of petroleum in San Juan ■county, and indications are reported in the Salado region near Santa Kosa in (xuadalupe county, as well as in Colfax, Eddy, Lincoln, Otero, and Union covm- ties, all of v;hich remain to be tested. Neir Ydi'l'. — For the sake of conducting the Imsiness of collecting the crude petroleum in a convenient man- ner, and keeping the same grade of petroleum together, the producing areas in the several states ha\-e been divided into districts. These districts are not always separated by state lines, as in several instances a pro- ducing area extends from one state into another, and ■ the complete separation of the products of the diflerent states is more or less dithcult. This is particularly so in the Appalachian field. The productive area of petroleum in New York is located in the southwestern portion of the state, and embraces the most northeastern part of the Appalachian field. There are two districts, one known as the Alle- gany distrit-t, which is entirely within the state, and the other as the Bradfoi'd district, which extends as a continuous producing area into Pennsylvania. The entire production of petroleum in 1902 was l.ir.»,730 barrels, valued at §l,53ti,S.">2, an average (if ^1.3<;T per barrel. The Tuimber of l)arrels produced in I'.H )•^ showed a decrease of 7.2 per cent, yet the value of the produc- tion increased $Ti(,S44. as compared with I'.tol, Diu'ing 1902, 8,443 wells were repurtetl by 2,123 companies nr individuals. There were exist f(ir many years. The field in the northwestern portion was de- veloped in 1885. There are two well-defined grades of petroleum produced. That in the southeastern poi-tion is similar to the peti'oleum iiroducefl in Pennsyh'ania and West Virginia: that in the nortliwestein ^lortion is a peculiar variety of petroleum, containing a considei'- able percentage of sul])lnu'ete(l hydrogen. For years it was extensively used as a fuel [)eti'(ileum, as the sul- phureted hydi-ogen im})arte(l a \'ery disagreeable odor to the refined products. It was only after se\-eral years that it was successfully relineij. The total })ro(lucti(jn of Ohio in 1902 was 2i,nl4.2:;i barrels, valued at $20,757,359. Of this amount there were 5,13(i,3(i(i barrels produced in the southeastern portion, which is a part of the Appalachian field, and 15,877,730 liarrels produced in the northwestern por- tion, known as the Lima-Indiana field. There was also a very small amount of lubricating petroleum produced in this state, in the Mecca and Beldcn fields, amount- ing to 135 bai'i-els. This commanded a high price. The \alue of petroleum produced in the southeastern portion of the state was $6,471,821. That produced in the Lima-Indiana portion was valued at $14,284,072. The output of tlie Mecca and Belden pools was valued at $1,466. Ohio has produced 24.4 per cent of all the petroleum that the United States has produced since the beginning of the petrf)leum production. The total number of wells completed in the state during 1902 was 5,31.'-1. Of tliese 3,532 were in the Lima-Indiana Held and I,7M in the southeastern field. Of the total muuber Slt4 w(>re dry and 4.419 productive, which includes 3 flowing wells. There were all told 39,056 producing wells, and 2.533 wells were abandoned. The total (|uantity and \alue of crude petroleum produced in Ohio in all lidds during 1902 and 1901 are shown in the following table: Table 3(i. — I'dUiI ijinnitili/ iiml ruhn: of criiih' pelrolfum produced in Ohio: 190e and 1901. 1902 (iuftntity ( barrels).

Thi.s Is the highest grade natural petroleum produced in the United States, but the demand for it is very small and operations are at a standstill. The average price for the Mecca oil in 1902 was $15.91 per barrel, or about 38 cents per gallon. This is much greater than the price of the manufactured article, whicli has ill a measure driven this natural product out of the market. UMuhiima. — There are many natural petroleum seeps in this territory, but nothing in the way of established production of petroleum was reported for 1902. Some oil is produced quite near the boundary line of Indian Territory. In addition numerous springs and wells have indications of petroleum, and liquid ;ind solid asphalt have l)een found in shafts and water wells, (luthrie, Lawton, Fort Sill, Richards, and Crranite all have a number of natural vents, showing both IDetroleum and natural gas, and in all probability a few years will see this territory placed on the list of regu- lar producers. (frt-gon. — A number of test wells were drilled in Lane, Douglas, Jackson, and Wasco counties, none of which found petroleum or natural gas. In Josephine county there are several springs reported on which a film of i^etroleum collects. I\iinKylr(inia. — Of the entire production, of petro- leum in the United States since the first discovery of the oil in 1859, Pennsylvania has produced one-half of the entire output. The production of ])etroleum in Penn.sylvania in 1902 was 12,063,880 barrels, amount- ing to 13.5 per cent of the total, valued at $15,266,093. The number of wells producing in that j^ear was 37,806. The number drilled was 3,034, of which 2,275 were pro- ductive and 759 were dry. The abandoned wells num- bered 1,879. There were 20,323 tanks of varying sizes at the wells, with a capacity of 1,864,755 barrels. The petroleum producing areas of Pennsylvania tire divided into districts on the basis of quality of output and county lines. A district is in some cases subdivided into pools which produce similar grades. The Bradford district is located in McKean county in the most northern poi'tion of the state, a portion of it extending over into New 1'ork. It was formerl}^ a very prolific region, nearly the entire area being under- laid by a productive sand 50 feet thick, but for several years it has shown the effect of drainage by a steadily decreasing output. In 1881 this district produced 23, ()(.)(), 0()O barrels of peti'oleum. Its production for 1902 Wiis 2,506,981 barrels. The Gaines district is located in Tioga county, just east of the Potter county line. It is the most easterly district producing petroleum in the United States. Its production for 1902 was 24,H81 barrels, which was 12,610 barrels less than that of the previous year. 'Tlie wells in this district are known as " flashy " — that is, tliej' pro- duced a large amount when first opened up, but soon dropped off' and became very small pi-oducei-s. Clarendon and Warren district includes the western portion of McKean county, the eastern portion of War- ren county, the northeastern portion of Forest county, and the northwestern portion of Elk county. In this district some of the finest petroleum produced in the United States is found, known as Tiona petroleum, which commands a higher price than the ordinary Penn.sylvania variety. The Clarendon and Warren district proper produced 468,420 ban-els in 1902,' which is a gain of 63,987 barrels over the previous year. The lower district contains the oldest wells in the Appalachian field, along the valley of Oil creek. Some of these wells have been producing over twenty -five years. The district includes a portion of Forest, Ve- nango, Clarion, and Butler counties. There is a great number of wells of small production in this district. The production in 1902 was 4,754,979 barrels, which is a decrease of loO,(»70 barrels as compared witli the pre- vious year. Many deep wells were drilled in the new Speediley field, near the old Modac pool, in Butler county, and there wei'e also a nunil)er of large wells secured in the Fourth sand near Middletown, which, however, rapidly declined. In the Allegheny county district no new pools were developed in 1902. This district produced 1,376,212 barrels in 1902, which was a decline of 64,755 liarrels as compared with the previous year. This district con- tained the famous McDonald pool, which in 1891 in- creased its production to 1(.>,317,258 barrels. The Washington county district produced 1,396,831 barrels in 1902, which was a gain of 96,432 barrels over the previous year. There were no new pools dis- covered, but several extensions of the older pools were developed. Beaver county district produced during tlie vear 19(i2 528,734 barrels. There was a decline of 27n.544 bar- rels in 1902 compared with 1901. Gri'ene county district also showed a slight decrease in 1902, when the output amounted to 721,574 barrels again.st 771,708 barrels in 1901. All the wells drilled 744 MINES AND QUARRIES. in tliis section are from 2,40(1 to :-5,(iO() feet in deptli, whicli makes the (li'illinu- und operatino- exjieii.siA'e.

Some of the ohler wells in this region are remarliabh^, on acconnt of their contin- uous production, the decline ))einu- verv sliydit during a .series of years. Franklin district is a subdi\'i,sion of the lower district, and has long l)een celebrated for the production of the finest natural lubricating petroleum found in the Ignited States. The production of this variety of petroleum is secured from the First sand, which has a thickness of about 5(» feet. This stratum is at a comparatively Table 39.— PKODUCTIOX OF (.'Kl'DF, PETKoLEI'M IX PKN [Barrels nf shallow depth, and is associated vrith large ((uantitie.s of salt water. Many of these wells produce only a few gallons of this superior grade of petroleum in a da}'. The production of this disti'ict in 1902 was 50,56.5 barrels, which showed a decline of 4,(!()7 barrels when compared with the previous year. The production of the Pennsylvania and New York fields for the years 1.S91 to 1902, inclusive, by districts, is shown in the following table, all of the districts being I wholly within Pennsylvania, except Allegany and a portion of the Bradford district referred to under the head of New York: NSYLVAXIA AXl) XKW YOliK, BY DI.STRICT.'^: 1S!H TO 1902. 42 giiUon.s.] YEAE.

This well at a depth of 27<) feet struck a de- posit of petroleum which alone has produced nearly 40,000 barrels up to the clos(.' of 19; ;2. It would seem that this well pierced a ca\'ern either in llic Clinton limestone or the upper Hudson ri\'cr formation. The petroleum is of a light green color with a specific gravity of 0.846 or 35 ' Baume. During I'.tol the large tanks near tliis well were connected liy a jjipe line with the Slickford pool in Kentucky, a distance of 20 miles. During the year 1902 a few small wells wei'c openi'd in the \'icinit_y of this remarkable well wliich helpetl to increase the production in this state. There w(M'e a nunil)er of wells completed in Pickett, Fentress, and Suujner counties, se\'eral of wliich li:id a considerahle .showing of petroleum oi' natural gas; the greater por- tion, liowe\'er, wer-e destitute of ]>etroli'iini in sulhcient (juantities to l)ccome paying wells. The numerous sui-- face indications o\'er a large area in this state have generally i)rove(l misleading. There seems to be an absence of an oiieii, ])orous. continuous bed that is ca- pable of furnishing a reservoir for the accumulation of l)etroleum. The wells that so far ha\'e proved to be pi'oducers, in greater- or less amounts, seem t<) draw their supply from a cre\ice in the stratum or a cavity in the limestone formation. Ti'.ciiH. — For a number of years the state of Texas l)roduced an insignificant amount of pt'troleum from Sour Lake, Nacogdoches, and the San Antonio fields. Its remarkal.)lc output in 1902 placed it second in the list, ne.xt to Ohio. The year l.S9(; was notaljle for the ; opening of the Corsicana petroleum held, in which a considera.l)le quantity of a very x'aluable petroleum was discovered. This peti'oleuni is rather dark in color and rangi>s from H.s to 40"^ Baunie. A few vears later a rehnery was ei'ccted at Corsicana, where almost the entire production has been successfulh' retined. On .(unuary lo, 1901, a very remarkable W(dl was I'F/rROLEUM. 745 completed in southeastern Texas, about -i miles south of Beaumont, in Jeti'erso.n county, and about i^n miles north of the Gulf of iMexico. At the rlosc of liH)^ there were some 120 wells producing in this locality. The producing area is confined to about 1S5 acres, on an elevation or mound which rises to about 15 feet above the general surface of tlu> plain. The sunnnit is nearly -10 feet al)ove the level of the s(>a. The wells are usually slightly over 1, ()()(» feet in depth, and orig^ inally were gushers. Some of them in the early hist(jry of the field produced as nmch as Tr),(H.H» barrels per day. Outside of this inuuediate locality deserihed, nothing but dry holes have bren developed, although some of these wells have been drilled to a depth of from 2,5()U to 3,0(10 feet. Probably no other event in the development of the petroleum industry in the United States created such a prof(.)und sensation as the opening up of this iirolitic territory near tidewater. The productivi> area near the original well during the summer and fall of 1!.»01 and the early part of 1902 was crowded by a great number of wells, many of which Avere productive, although the output of the later ones was insignitieant in comparison to the output of the earlier. The first w(dl in this pool was located by Capt. A. F. Lucas, who was attracted to the locality by the existence of strong sulphur and acid springs and the presence of pure sulphur, together with a considerable outflow of natural gas. Two unsuccess- ful attempts had formerlj^ been made to test this local- ity. A considerable amount of gas pressure in pockets was developed above the oil producing horizons, and this in some instances blew out great volumes of sand and water before it became exhausted. During the latter portion of 1901 another large pool was partiallj- developed at Sour Lake, 20 miles north- west of Beaumont, underlying the shallow wells that were originally drilled in this locality. Jn November of that year a well was completed to a depth of 1,500 feet which encountered more or less loose sand alter- ; natingwith beds of gravel. At a depth of between 850 and 880 feet a deposit of sand was found which gave a large flow of hot sulphur water at a temijerature of about 100° F., accompanied by some showing of petro- leum. At a depth of 1,(J-10 feet four distinct sands were encountered. These loose sands contained some petro- leum associated with hot water, but no considerable quantity was developed. About the middle of March, 1902, a gusher was opened up at a depth of 683 feet, after H) feet of very promising oil sand had been penetrated; when the water became exhausted the well began to flow vigorously, accompanied by the outburst of loose sand, which on several occasions complete!}' shut ofl: the petroleum. By the use of casing with large)' perforations than had previously been used, the inrush of loose sand was over- come, and many very productive wells were secured. The gravity of petroleum produced in this region ranges from 22'-' to 23 Baume, equal toaspecitic grav- ity of 0.92.

In the latter pai't of 19(ll and the year 1902 a numbci' of pipe lines were con- structed I'eaching from Beaumont to Boj-t Arthur and Sabine Bass. Two pipe lines were constructed from Sour Lake to Beaumont. Tweh'e nn'les northwest of Sour Lake, in what was known as the Saratoga district, sevei'al producti\e wells of moderate capacity were drilled with promising indi- cations of an increased production. In the (dd Nacog- doches district numerous shallow w(dls were drilled previous to 1895, but no very large producers were secured. A considerable amount of money has been in\'ested in drilling wells and Iniilding a ]jipe line to the railroad in this locality, but operations have Ijeen of late years practically abandoned. In the Bexar county district small (Quantities of h(>avy petroleum were produced from wells at a depth of t)()(.) to 800 feet. This pool is located near San An- tonio. The number of wells drilled during 1902 was 252; of these 216 were productive and 36 were dry holes. The niunber of flowing wells was To, and the total luuu- ber of pumping wells was 782, making a total of s52 productive wells. There were 67 wells abandoned dur- ing the year. The numlier of tanks at the wells was 1,010, with a combined capacity of 1-, 917, 923 liarrels. The localities in which petroleum has thus far been found are shown in the following list, arranged alpha- betically by counties, the list being taken from Bulle- tin 18 of the Fniversitv of Texas: Anderson county, New Palestine, sand impregnation; Bastrop count\', near Elgin; Bell county, western l)art, small quantities near Belton; Bexar county, Dul- nig place, 7 miles south of San Antonio, J.

The total quantity of crude petroleum produced in 1902, was 18,515,017 ))arrels, of which l,s,i)S3,05S barrels were sold and 431,r!5'.i barrels were hidd in tanks by the producers. It is estimated that at the close of 1902 storage tanks in the state contained alxiut 7,B0n,(i()O l)arrels, leaving 11,215,017 barrels as the ([uantity wdiich was either con- sumed locally or shipped fi'om the state. The total production in 19m1, excluding stocks, was 1, 393,65s barrels. The gain of 1902 over 19(.»1. excluding stocks, amounted to 311.6 per cent. The value of the crude petroleum produced in l'.H)-2 was $4,174,731, an average of 22.55 cents per barrel. Compared with I'.Hil the total value, excluding stocks, shows a gain of 22o per cent.

Large bituminous coal deposits and a thinl}' settled countr}' have jirevented more than a slight demand for it. There has been, however, since 1893 a regular production of superior lubricating petroleum at Salt Creek, 50 miles north of Casper, to which place it is hauled bv wagons and refined. In the southwest- ern portion of the state, at Spring \'alley, Uinta county, some petroleum of light gravitv and superior quality has l_)een produced, l)ut not as yet in commercial quan- tities. There are numerous petroleum seeps in the west- ern and central portions of Natrona countv, and outcrops of sandstone largely' impregnated with petroleum on the north flank of the Rattlesnake range of mountains. In the Pope Agie district, in Fremont countv. several 748 MINES AND (,)UARRI?:S. successful wells that flow iiiitunilly have lieeu drilled. Some of the wells drilled in ls84 still flow petroleum when opened up. It is reported that 4.0(H) harrels were produced in this region and allowed to i-emain in earthen tanks, owing- to cost of transportation, (mljr a small portion lieiny used for fuel and lulirication. This petroleum is cjuite heavy and dark and its specific gravity varies from 18-' to 23-' Baunie. KEVIEW BY YEARS. IS'.K) TO THE CLOSK <.)F 19()1. A summary of the principal features in the develop- ment of the petroleum industry is herewith presented; it covers the 3'ears from the publication of the Eleventh Census in ISttO to the close of I'.KJl. 1S90. — One of the most notal)le features in the petro- leum industry in the I'nited States in 1890 was the enormous increase iu the production, a gain of l(.i, (')(;(!,( 159 barrels being made over the production of 1889. The principal increase was in Pennsylvania and New York, the increase amounting to 6,970.77:-! barrels. Discov- eries of petrrjleum were numerous in Pennsylvania, and the borders of some of the older distiicts had to be extended to emln'acc a wider area of pi'ciductive terri- tory. The sections conspicuous for heavy gains were the Glade Run pool in Butler county, the Shaniiopin pool in Beaver county, and the Montour, Wildwood, and Chartiers pools in Allegheny county. The in- creased production in Ohio amounted to 3. 6.53, 190 bar- rels and was general throughout lioth the Lima and the southeastern fields. The average value of pipe line certificates in the Penn- sylvania field declined fronj !»4J cents per l)arrel in 1S89 to ^^i'ji cents in l.S9(;). making a net loss of 7^^ cents. The average price (jf Lima (Ohio) petroleum advaiu'ed from 15 cents per Ijarrel in 1889 to 3<) cents |')er barrel in 1890. The state of Indiana was credited with a production of 63,496 barrels in 1890. as compared with 33,37.-1 bar- rels in 1889, the first year in which Indiana appears in the list of productive states, ^\'est X'irginia produced slightly less in 1890 than in 18S9. Although the orig- inal well at Mannington was opened up in October, 1889, it retjuired time to drill the deep mcIIs of that region and to connect them to pipe lines, and the effect of the greater " strikes "" upon tlie production was not at once apparent. 1891. — The amount of petroleum produced in lS9l. 54,292.6.55 barrels, was larger than that of any ]ii'eced- ing year and was not exc(M:'ded until bs96. The most important event that mai ked the year was the opening up of the )-e,markable McDonald petroleum Held, in Allegheny and Washington counties. Pa., in Jidv of that year. By September the ]ii-oduction of this dis- ti'ict reached 41.000 bai'rels ])er diiy. I( is estimated that the total jirodiK'tion of tije McDonalil lidd for the last, six months of 19o| w.^is over (;,(I(H),(H)() han-els. This was ]i|-obably the most pi-olilic Held of ix'l roleuin ever developed in the Appalachian field, when its area is considered. The oil bearing sand was composed of beautiful ([uartz pebbles from the size, of a pea up to that of a hickory mit. It gave up large quantities of petroleum with great rapidity. In this great reservoir the wells soon ceased to )>e more than ordinary producers, but a few months sufficing to measurabh' exhaust several of the wells which, when first opened up, flowed at the rate of 15,000 to 18,000 barrels per day. The Wildwood fiehl, in Allegheny county, was also a factoi' in increas- ing the Pennsylvania jnoduction, although to a much less extent than the Mi'Donald pool, and Butler (/ounty furnished scune new and fairly producti\e \vells. There was a considerable decrease in the production of the other Peiuisyh'ania districts. There was a large decline in southeastern Ohio, owing to the low prices that pre- vailed. The production of southeastern ()hio in 1890 was 1.108,334 barrels, as compared with 422.883 bar- rels produced in 1891. On the other hand, in the Lima field there was a large increase in production. The Appalachian field produced in the year 1891 a total of 35.84iS.777 barrels, wliieji is the greatest pro- duction on record with the exception of the year 190(.), when the production was slightly in excess of these figures. This large jn-oduction of iietroleum had the efl'ect of reducing the price so that the average price quoted for the yeai' 1S91 was 67 cents, as compared with 7Hil cents in Iss'.i. In this year "West ^'irginia began to be conspit'uous as a producer of petroleum. The production of 1S91 was 2.4o6,218 barrels, which was due to the opening up of the new field extending from ]\It. Morris, near the Pennsylvania state line, to Man- nington. in Clarion county. Indiana also began to be conspicuous as a jiroducer. ha\"ing increased its produc- tion largely o\'er that of 1S90. 1S9:2. — The jiroductiou in 1S92 showed a considerable falling oti', due largely to the decline in the yield of the McDonald field in l*ennsyl\ania. West \'irginia in- creased over a million barrels in ]ir(_)duction, which was due to the increasing yield of the Manningt(_in field and the newly de\eloi)ed Sistei-s\ille pool. The Gordon sand, underlying the Big Injun sand, was discovered to be pro(lucti\e south of Mannington. There was a re- duction in the output of northwestern Ohio, an increase in that of s Trenton formation. Up to this time a greater poi'tion of the petroleum of th(^ Lima-Indiana fields, in Ohio and Indiana, had been sold foi' fuel. In this year an increasing amount was marketed for retin ing. owing to the process lately perfected for the i'iM)lo\al of the sulphur. The average price n^ceived for the petroleum produced in the .\])palachian field was 55l; cents p(M- barrel, which, with the c^xci^ption of 1S61. is the lowest (piotation on recoi-d. The price t>f Lima- Indiana petroleum ^^as ."Ui:,' cents jxm' barrel. PKTKOLEUM. 74H There was an increase in tlie exports of petrolciiiii and its products. 1S9.1. — Tile important teatures connected witii tlie production of petroleum in 1S1»P> were a decline in the output of the older fields, especially Pennsylvania; an increase in the amount oi pi-oduction in southeastern Ohio, West Virginia, and Indiana; the slight increase in price, and the increase in the refining of Lima- Indiana petroleum. There was also an increase in the cjuantity exported. Practically all the petroleum pro- duced came froui the Appalachian field, the Lima- Indiana field, the Florence field of Colorado, and the districts of southern California. The decline in the entire production in 1893 as compared with 189'i was 2,078,591 barrels. There was a large increase in tlie output of West Virginia and Indiana. The decline in the Appalachian products of 2,067,32i! barrels nearly accounts for the entire shortage. The average price of certiticate oil in the Appalachian field was 64 cents per barrel, an increase of 8ft cents over that of 1892. In the Lima field the average prit'e of petroleum in 1893 was 47.25 cents, an increase of lOij cents over that of 1892. The increase of petroleum exports in 1893 over those of 1892 was nearly f)(),O(i(),O(:)0 .gallons, and the total exportation of all varieties of petroleum amounted to 804,221,230 gallons, the largest up to that date. ISQIj,. — The notable events in the progress of the petroleum industry in 1894 were the development of the Ormsby district, in the Bradford field in northern Pennsylvania, the opening of the Williamstown pool, in Wood county, W. Va. , and the discovery of a Berea sand pool near Steubenville, Ohio. There were also some promising developments near Marietta, Ohio. The vear was also notable for the advent of the state of Wyoming to the list of oil producers, 2,369 Ijarrels being produced by this state. The quality was that of a superior luljricating petroleum. The year showed a very slight increase in production over that of 1893, but the increase in value was over 16,000,000. In the Appalachian field the comliined product of New York and Pennsylvania showed a decrease of 1,294,523 bar- rels. West Virginia showed a slight increase over the preceding 3'ear. Southeastern Ohio showed quite an increase, amounting to 581,976 barrels. In the Lima (Ohio) district there was a decrease of only 38,960 bar- rels. Indiana showed an increase of 1,353.373 barrels, a gain of 58 per cent. The average price of the Appa- lachian petroleum in 1894 was 83|- cents, a gain of almost 20 cents per barrel. The average price of the Lima-Indiana petroleum was 48 cents a barrel, general average price 72 cents. 1895. — The notable features of the year were the nearly identical production of the Appalachian field with that of 1894; the increased production in Ohio, Indiana, and California; the advance of Ohio to first place, its production for the first time being greater than that of Pennsylvania; the decrease in stodis and the rise in price; and the further extiMision of profitable producing districts, including the opening up in A\ est Virginia of the Elk Fork pool, east of Sistersville, and of another on Indian creek near the Big Moses well: and successful tests in southeastern Kansas. There was a slight increase in the combined production of New York and Pennsyl\-ania and an inci-ease of over vwo million barrels in the production of the Lima (Ohio) field. A sliglit dedine, amounting to 457,499 barrels, was recorded in the production of ^Vest Virginia. There was an increase of aljout 7i)i),(K)0 barrels in Indiana and of o\er50(t,000 barrels in California. The total production in 1895 was 52,892,276 barrels. The stocks of crude petroleum in the Appalachian field at the close of 1895 were 5,344,784 barrels, as compared with 6,4i»9,880 barrels at the close of 1894; in the Lima- Indiana field there were 21,494,848 Ijarrels, making a total for I)oth fields of 26,839,632 barrels at the (dose of 18'.>5. The price for what ^vas known as Pennsylvania cer- tificate oil was $1.35^^ cents, as compared with 83^ cents in 1894, a gain of 52 cents. In the Lima-Indiana dis- trict the average price in I8'.t5 was 71f cents, as com- pared with 48 cents in 1894, a gain of 231 cents. The a\'erage price of the entire production was $1,089 per barrel in 1895. 180G. — This year was remarkable iov the large increase in the i^rodui'tion \\liichcame principally from the state of ^Vest Mrginia and the Lima-Indiana district in northwestern Ohio, and from the Watsonville pool in McKean county. Pa. There was an increase in the amount of stocks held and a decrease in the price. The entire production for the year 1896 Avas 6n,96u.3<.il barrels, larger than that of any previous year in the historj' of the industry, and a gain of 8,068,085 barrels over 1895. There was a slight increase in the combined production of New York and Pennsylvania, with an increase of 4,400,000 barrels in Ohio, and an increase of 1,900,000 barrels in West Virginia. A slight increase is to be noted in the production of the state of Indiana, and a large increase in the state of Kansas as compared with that of the jDrevious year. ! The new field at Corsicana, Tex., was first opened up during 1896 and produced l,4i)0 Inirrels. The total amount of stocks held in the Appalachian and Lima- Indiana fields, at the close of the year 1896, was 33,048,492 barrels, as compared with 26,8311,632 l:iarrels at the close of 1895, a gain of 6,2(»8,.S6ti barrels. There j was a decrease in the price of petroleum. The average ' \'alue of what has l)een called Pennsylvania certificate 1 oil, in the Pennsylvania field, was §1.18 as compared with 11.36 in 1895, showing a decline of 18 cents per barrel. In the Lima (Ohio) field the price fell from an a\-erage of 711 cents in 1S95 to 661 cents in 1896, a decline of 5 cents per barrel. The total value of all of the petroleum marketed in 1896 was $58,518,709. an 750 MINES AND QUARRIES. average of about 95.11 cents per Itarrel. This was an increase in value of only $S;27,-±30 over the preceding- year. 1897. — The total quantity of petroleum produced in the United States in isyj was (:;0,J:T5,51<', l)arrels, a de- crease as compared with 1806 of only 484,84,5 barrels. There was a slight increase in the production of the Appalachian field as a whole, which came principally from "West \'irginia. There was a decided decrease in the yield of the Lima-Indiana field in the states of Ohio and Indiana. There was also considerable decrease in the number of wells drilled in both of these states as compared with 1896. The production of petroleum in Texas amounted to 65,975 barrels, as compared with 1,450 barrels produced in 1896, and nearly all of it was produced in the Corsicana field. There was an increase in stocks and a still further decrease in price. There was a decline in value amounting to |17,589,(.»98. The average j^rice per barrel for all the petroleum produced in 1897 was 67.7 cents as compared with 95.9 cents in 1896. There was a decrease of 2,45i',837 barrels in the production of the Lima-Indiana field. Colorado increased its output by 23,484 barrels, and the California field by 65(1,634 barrels. The largest proportional gain, however, was in the Corsicana field in Texas. The stocks in the Appalacliian field at the close of 1897 were 11,010,044 barrels, an increase of 1,264,322 barrels. In the Lima-Indiana field the stocks of petroleum at the close of the j'ear 1897 were 22,762,779 barrels, a loss of 539,991 Imrrels. The total stocks in both fields at the close of 1897 amounted to 33,772,823 barrels, a gain of 724,331 barrels over those at the close of ls',)6. The average price of cer- tificate or credit balances of Pennsylvania oil in 1897 was 78:1 cents, as compared with §1.17^ in 1896, show- ing a decline of 39i cents. The average price of Lima (Ohio) petroleum was 4s cents, as compared with 66f cents in 1896-, a decrease of 18|- cents. 1898.— Th& quantity of petroleum— 55,304,233 fiar- rels — produced in 1898 showed a decrease of 5,111,283 barrels as compared with the 6(), 475, 516 barrels produced in 1897. There was a decrease in both tiie Appalachian and the Lima-Indiana fields. The a\'erage price paid for Pennsylvania petroleum was 91s cents per bai'rei, as compared with 61J cents per barrel for the produc- tion of the Lima-Indiana tiekl. The initial well in Scio, Harrison county, Ohi(j, was conjpieted in August. There was a large increase of production in California and Texas, but a decrease in Indiana. There was a decrease in the number of wells drilled in the Appalachian and the Lima-Indiana fields. The total nunibei- drilled in liolh these fields was 7,l8(i, of which 1,539 were dry, as compared with S,558 drilled in 1897, of wliicii imnd)er l,9(;4 were dry. The total stocks of these fields at the chise of ]«9S were 26,967,495 barrels, as compared with 33,772,823 barrels at the close of 1S97, a decrease of 6,8(»5,32H barrels. Stocks cli- creased and the price increased. Tlie exports decreased as compared with 1897. 1899. — The entire production of the United States was 57,070,850 barrels, as compared with 55,364.233 barrels in 1898. The year was conspicuous for the in- creased pi'oduction Iti southeastern Ohio, amounting to over 2,50(>,(»0() barrels, principally from the Scio pool, Harrison county, which added over l,<;()0,iH)n barrels to the output. The peti-olcHim of this pool was found in the Berea formation at a depth of alxjut 1,200 feet, l)eing(juite evenly distributed and of a very supeilor (juality. There was a decrease in the production of Pennsylvania, Colorado, and Kansas, while all the other states showed an increase. There was a considerably increased production in the state of Texas. The aver- age price of all of the petroleum ])roduced in 1899 was fl.l32, as compared with 79.8 cents in 189s, showing a gain of 33.4 cents. The average price of what is known as Pennsylvania certificate oil, which includes about 96 l^er cent of the Appalachian production, was ^1.29i; jjer barrel in 1899, as compared with 91^ cents in 1898, an increase of 38i cents. The average price of Trenton I'ock, oi- Lima-Indiana, petroleum was 8s^t cents in 1899, as compared with 59.4 cents in 1S98. an increase of 29.2 cents per barrel. There was a decrease in the stocks in 1899, due to shrinkage in the Lima-Indiana district, as the total stocks in the Appalachian field increased b}- 1,661,588 barrels. At the close of 1S99 the total stocks held in the Appalachian and Lima-Indiana fields amounted to 23,997,118 liarrels, as compared with 26,967,495 bar- rels at the close of the previous year. The decrease in 1899 was 2,97 or value of the petroleum at the wells, the |)rice of $1.19 being reached this year, which was the highest since 1S77; the average ]ii-ice of Pemisyh'ania petrohnun ^\as $1.35:^ per l)arrel. The price of Lima-Indiana petrohnnn advanced from S9i to 98^ cents. The exports of petrcjleum and its j)rodut'ts also showed a considerable gain in ([uantity and \-aluc. 191)1. The production in f90l was again greater than foi- any i)revious year. It was 69.;')S9,194 barrels, an increa.se of 5,768,665 barrels. There was a most PETROLEUM. 7fA remarkable increase in the prodnotion in both Texas and California, which combined amounted to about ,S,()00,(IOO barrels. There was a decline in the product of West Virginia amountino- to over ^,(I00,0()(,) barrels. There were also slight declines in New York, Pennsylvania, Ohio, and Wyoming; all the remaining i)il producing states showed an increase. The average price of all the petroleum produced in 1901 was 05.7 cents, as compared with §1.1!)1 in 1900, a decrease of '2oA cents per barrel. The average price of Pennsylvania ccrtihi'ate petroleum was $1.21 per l)arrel, as compared with !pl.;>ri-| per liar- rel in 190O, showing a decline of llf cents. The aver- age price of Lima (Ohio) petroleum fell from 9iS-J cents in 1900 to Nrt cents in 1901. There was also a decline of 37.7 cents in the average price paid for California petroleum and a decline of 76 cents per barrel in the average price of the Texas production. There was an increase in the exports of petroleum and its products (mineral oils), which for the first time exceeded 1,000,000,000 gallons. The total value of the exports was, however, slightly less than in 1900. On January 10, 1901, an immense gusher was drilled near Beaumont, Tex., and flowed a stream 150 feet high and 6 inches in diameter. Before it was controlled it is estimated to have produced not less than 500,000 barrels, averaging not less than 60,000 barrels per day. The year was also notable for the organization of an immense number of stock companies in California and Texas, which secured a large amount of capital. Many of them never produced a single barrel of petroleum. The Boulder field in Colorado was just opening up at the close of the year. It created considerable ex- citement, and a large amount of capital was invested in stock companies. These investments in most cases resulted in disappointment and a total loss to the investors. REVIEW OF THE INDUSTRY IN FOREIGN COUNTRIES. Canada. — Since the year 1S62 Canada has produced a considerable quantity of petroleum. The output, how- ever, does not supply the amount necessary for home consumption. In 1902, 11,389,390 imperial gallons of refined petroleum were produced from the crude in Canada, and 13,220,005 imperial gallons of petroleum and its products were imported. An import tax amounting to about 5 cents a gallon is imposed. For a number of years the production in Canada was over 7(10,000 barrels, but there has been a gradual decline in the output since 1898. The production in 1902 was 520,000 barrels. The main productive territory is situated in Lambton county, Ontario, the two princi- pal districts being Petrolea and Oil Springs. In c[ualitjr the petroleum produced in this portion of Canada is very similar to that produced in the Lima- Indiana field, which contains a considerable proportion of sulphureted hydrogen, and it has been successfully re- fined in former years at Petrolea and in later years at Sarnia. There are other sections in Canada in which more or less petroleum is known to exist, but which have up to the present time yielded little or no output. In the vicinity of Moncton,,Ncw Bruns\vick, several wells recently completed have produced ]5etroleum in sufficient quantities to be successfully operated. Other localities in which peti'oleum is kncjwn to exist are (iaspe Itay in Quebec and near Lake Ainslie in Nova Scotia, hut no profitable production has been secured. Tl)ere are also indications of peti'oleum along the northwest coast of Newfoundland. A nundier of wells have been drilled and petroleum in small (pVantities has been found, but up to the present time no successful operations have been developed. In the southwestern portion of Alberta a well was completed during the year 1902 which was I'eported to have found a considerable flow of petroleum. A well was also drilled near Calgary. There are many local- ities along the Athabasca river in Athabasca district where petroleum, and especially natural gas, are more or less abundant in surface indications. Although sev- eral test wells have been drilled in this section no large quantities of either have been developed. Peru. — For a number of years this country has pro- duced a considerable ({uantity of petroleum. The pro- duction for 1902 was, in round numbers, 60,0(H.t barrels. The varietj' is similar to that produced in California, and is inferior in quality to the output of the eastern portion of the T^nited States. The scarcity of good coal along the western coast of South America has added considei'able interest to the development of pe- troleum in Peru. However, the production seems to be on the decline. Outside of the United States, Peru and Canada are the only counti'ies on the Western con- tinent that have produced petroleum in commercial quantities, although it is known to be widely distrib- uted in Argentine, Brazil. Colombia, Cuba, Ecuador. Mexico, Trinidad, and Venezuela. In most of these countries there are local springs and shallow wells, worked generally in a very crude manner by the na- tives, which have produced a small amount of crude petroleum. i?».s•.svV^ — For the first time in eight vears, Russia in 1902 showed a decreased output of crude petroleum. The decrease from the output of 1901 amounted to 4,628,511 barrels, a falling ofl' of about 5 per cent. The principal reasons for the decline seem to have been the want of organization among the producers, insuffi- cient means of storage and transportation, and the taxes imposed by the (Toveriiment upon certain terri- tory. A number of large spouting wells were drilled during the year, one of the largest of which was on the Roths- child plot. No. 25, at Romany, Bibi Eibat district. For a time this well yielded 80,000, barrels per day. Another large well near by produced at the rate of 100,000 bar- rels per day. The depth at which large spouting wells 752 MINKS AND QUARKIP]S. are .secured is u-radually iiicicusiiio-, uddino- larg-ely to the expense. Often several years are consuinod in completing- one of these very deep wells, which require manv feet of casing, l)eg'inning' with a size as large as 26 inches in diameter and ending with a diameter 10 to 12 inches. In some of them the wrought iron pipe and easing used weighs as much as IH) tons, which, together wnth the time consumed in drilling, entails a cost of from $15,000 to $:2o,oo(i. During the year a new field was discovered hy the drilling- of a well near Berekei station, iTo miles north- west of Baku. The (Irosni field, 500 niik's north of Baku, has produced considerable petroleum for the last five years. The greater portion, or i>5 per cent, of the petroleum continues to be produced from an area of al:)out 10 scpiare miles in the Apsheron p(>ninsula near Baku.

Only 12.3 per cent of the illumi- nating and lubricating products was marketed in the great inland portion of Russia. The average price of crude petroleum at the wells at Baku in 1902 was (i.H5 kopecks per pood, (U- 3.42 cents for 5 gallons, or 28f cents per barrel, as compared with 8.25 kopecks per pood, or 32| cents per barrel, in 1901. world's rRODUCTION. One of the conspicuous features of the world's pro- duction of petroleum in 1902 was the remarkable increase in the output of the inferior grades in the United States. Of the world's production the United States produced 47.9 per cent in 1902. In 1901 it produced 41.84 per cent. Another ver}' important feature was the decline in the Russian production which, in 1902, amounted to 43.50 per cent of the world's production, as compared with 51.38 per cent in 1901. The United States and Russia in 1902 produced i)L.44 per cent of the world's production, in I'.tOl they pro- duced 93.22 per cent, and in 1900 their production was 94.11 per cent.

Numerous theories ha\'e l)een tidvanced as to the ori- ginal source of thecar))ides and hydrocarbons tind their combinations, entering into the ft.irmation of petroleum, and many scientists of note have a particular theory, but there appears little possibility of reaching an agree- ment in the matter in the netir future. Experiments in the laboratoiy have been made so as to combine the elements artiticially ;ind the resultant, in most instances, has ])eena liquid, which in appearance and composition is very similar to the natural petroleum. Petroleum has also been produced by the distillation of shales, and there are man}' upholders of the claim that the forma- tion of petroleum is due to the naturtd distillation liy internal heat of the shales and hydrocarbons found in the earth's crust. Its origin is one of the unsolved problems. The various theories advanced by men of science to account for the formation may be in most cases nar- rowed down to two, each of which has found numerous supi^orters. These are — tirst, its physical origin by the distillation of organic matter in the sedimentary strata, either animal or vegetable; second, its chem- ical origin from inorganic matter or direct production by the decomposition of carbides through the action of steam deeply buried below all sedimentaiy strata. In all of the known tields of the world the occurrence of petroleum is limited to comparatively small areas. The area of the same strata in which the petroleum is not found invariably covers a vastly greater tirea than the portions that are productive. This is the case also in some instances where the structural conditions may favor its accumulation, and the surrounding slates and shales are similar. When productive rocks can be traced to their outcrop there is invariably no trace of petroleum or asphaltum to be found in them. The wells drilled outside of these favored localities usually find no trace of petroleum or natural gas, although numerous .sands may have been pierced which are pro- ductive elsewhere and are sufficiently open and porous to be receptacles. Vlieiii iviil and2>JiljKical propcrfieH. — Petroleum, in both its liquid and solid forms, is largely made up of carbon and hydrogen. It ranges from 77'' Baume, or O.07BH specific gravity, in the case of the lightest naphtha, con- densed naturally from natural gas, up to between 1.1 and 1.3 in its more dense and .solid form, such as natural asphalt, which usually contains from 50 to 80 per cent of carbon, to 10 per cent of hydrocarbon. 754 MINES AND QUARRIES. and 8 to 10 per cent of sulphur. These solid forurs are widel_v distributed, vary oTeatly in composition, and are usually associated, in varying proportions, with more or less silica and carbonate of lime. Geiieral striictiiral vondifionfi iiiji iiniri id/ ucciirri'iict'. — There is avast difference in the character of petroleum produced in the United iStates and in foreign countries, and a great variety in the character of the strata which contains it. The infiltration of the petroleimi into dif- ferent sands and limestones has had much to do with imparting to it the varied phj-sical and chemical prop- erties. However, the structural conditions of these sti'ata and the position tliey must occupy in order to bring about a concentration of the petroleum are similar in all of the productive fields. Its occur- rence in small quantities in strata where the condi- tions necessary- for concentration are wanting has in many instances been the cause of financial loss and disappointment. Geological occurrenee of petroleum iitid nntiwnl (jiis in the United States. — The intimate association of the liquid and gaseous hydrocarl)ons has made it difficult to separate them when one or the other is discussed. The great deposits of petroleum in the Appalachian field are in a series of sand rocks reaching up from the Lower Devonian to the Upper Barren measures or Monongahela formation, less than lOo feet above the Pittsburg coal, and embraces not less than 50 distinct horizons. The greater portion of the production, how- ever, comes from the Catskill division. Upper Devo- nian, which group is petroleum l)eariiig from northern Pennsylvania, near the northern portion of Venango county, southwest to the Little Kanawha river in \\'est Virginia. In '\\^arren, IMcKcan, and Elk counties. Pa., productive sands are found lielow this group and are largely productive. They extend into south central New York and belong to the ]\Iiddle Devonian foi'tna- tion. The overlying Berea and the Pocono or Big Injun and Lower Carljoniferous sands are above the Catskill group in the geological scale, and are largely productive in West Virginia, southeastern Ohio, and to some extent in eastern Kentuck}'. The highest series of productive strata in the region east of the Mississippi river are composed of the sands of the uppt'rand lower coal series, which are productive in southwestern Penn- sylvania, West Virginia, and southeastei'n Ohio. Tiie sandstone series of the Appalachian di\'ision, in 1!»()'2, produced 36 per cent of the total production. Over 85 per cent of the petroleum produced in the United States from the beginning of production up to the close of 190i also came from the sandstone strata of the Appalachian field. Here there are 40 distinct hori- zons in 3, .300 feet of measures, and the individual bods of sandstone vary from 'i to VlO feet in thickness and differ ip texture from an open light coloi'ed sand with layers of pebbles, Avhicli is xci-y prolitic, to sand of a close and hard texture, wliich it is necessary to torpedo in order to secure production. The highest productive sand of any practical value in the geological scale is the Mahon- ing, or Dunkard, sand of Pennsylvania or the first Cow Run sand of Ohio; the lowest is the Kane sand in Elk and McKean counties, Pa., and the sands of western New York. The Venango county sands are made up of a series of from four to six distinct ))eds, separated by strata of slate and shale. These sands generally contain layers or beds of white pebbles, often capped bj- a hard siliceous portion and separated 1)}' beds of shale and slate ranging in color fi'om black to red. In Venango county the series has an average thickness of 300 feet from top to bottom, increasing to 430 feet at McDonald, in Allegheny county, Pa., and in portions of West Vir- ginia. There is a general thinning out of this group toward the west and it thickens toward the east. The}' are genei'ally known as the white-sand group. ]Most of the sands below, and including the Speechley and Bradford sands, are darker in color and finer in tex- ture than those above and are known as the dark-sand group. All of them consist of distinct layers, invariably capped by strata of dark slate or shale, which vary in thickness and allow the layers of sand to approach much nearer to each other in some localities than in others. The source of the peti'oleum in the Lima-Indiana field is the Trenton limestone, which has ]>roduced very largely since first disco\'ered in this field in'lS85. From its first discovery to th(> clos{> of I'.lOii, tiiis formation has produced it pei' cent of the total output of the United States. It is pi-oductivc oidy in the region which eni- bi'aces northeastei-n Ohio and c(>ntral Indiana, known as the Lima-Indiana field. This limestone, which is usually over 500 feet in thickness, has a series of por- ous streaks embedded in the regular strata, and these streaks differ in comjiosition from the great mass, being a dolomite which has re])hu'ed the carbonate of lime with crystals that are smaller than the carbonate crystal, and which do not, therefore, till up the oi'iginal space in the process of replacement. This changed and (_)pen conditions of the strata which inxariably contain the peti'oleum (often associated with large deposits of salt water) are found at intervals of from iJo to 3i!5 feet in extreme cases from the uppei' surface (.)f the limestone. The Trenton limestone is a remarkably regular and clearly defined deposit. The change from the Utica black slate, which cajjs it, to the rock is distinct and easily recognized by the driller. The horizon in which petroleum is found in Kansas and Indian Territoi'v corresponds to that of the salt sand group in West Virginia, located in the lower por- tion of the Pottsville grou]i. resting on the Mississip- pian limestone, which is in a general way equivalent to the sul)carboniferous limestone of southwestern Penn- sylvania and West Virginia. All the remaining pro- duction west of th(> Mississijjpi river is set'ui'ed from strata that arc nuich more recent, reaching from the Permian to the Quaternary. These newer productive PETROLEUM. 755 measures consist of much thicker strata — a thickness of 15, (too feet is recorded in localities — and are made up of tiie recent sedimentary deposits. The several pools west of the Mississippi river produced .37.61 per cent of the output in 1902. Clint'dt'ter and eo)iipo.sitii>ii of jydi'iilcuiii produc( d in tfu- United Stidiv. — The Mississippi river separates the petroleum fields of the ITnited States into two j^-reat divisions. The fields east of this line, to an almost universal extent, have developed petroleum with a parafBn base, while the helds to the west have, with a few exceptions, produced petroleum with an asphalt base. Crude petroleum with a paraffin base is gener- ally nuich lio-htor and is nuu'h more valual)le, owing- to the greater quantity and superior quality of the naph- thas and illuminating- and lubricating- derivatives it _yields,as well as the paraffin, which is secured from the heavier distillates after the lighter products have been extracted. On the other hand, petroleums with an asphalt base, in most cases, yield onlj^ a comparatively insignificant (juantity of naphtha and a much smaller proportion of illuminating- and lubricating products, which are of in- ferior quality, while the remaining distillates are prin- cipally valuable for fuel and as asphalts. The asphalt petroleums are also usually nuich heavier and are more difficult to transport by means of pipe lines, so gener- ally applied in the fields producing paraffin petroleum. These conditions restrict the market for asphalt petroleum, so that in general it is consumed as fuel oil, as distillates for eni-iching manufactured gas, and as asphalt. There are several exceptions to this generali- zation, however, as petroleum, in comiiaratively small amounts, is found in portions of Kansas, Texas, Indian Territory-, Colorado, and (Jalifornia that yields refined products little inferior to the best grades of paraffin oil. The products obtained by the refining of the Appala- chian petroleum, and of oils from the other fields, are given l.)elow, in percentages, in a series of statements representing general results. There are marked ditier- ences in the composition of crude petroleum and in methods of refining. These methods are often varied, to a certain extent, to meet the demands of the market.

This was owing to the presence of a large amount of sulphureted hydrogen, which seemed to be thoroughh' combined with the carbon and hydrocarbon which constitute the main elements of petroleum. By double refining the petroleum. howe\'er. and the oxidation (if the sulphur — the l)lack oxide of coppi.-r being used — the refiner has succeeded in producing an article which can scarcely be distinguished from the ))roducts of Penn.sylvania crude petroleum, although the p(M-centage of refined products secured is smaller.

The original crude oil from the Lima- Indiana fields contains nearly <.i.56 per cent of sulphur. The amount of sulphur found in the Pennsylvania petro- leum varies from 0.025 to ().(i()2 per cent. Nearly all of the sulphur in the Lima-Indiana petroleum goes over when distilled, being found in Itoth the light and heavv distillate, and it is necessary to oxidize the sulphur in order to remove it. The gravity of naphtha varies from 'MY- to 60'^ Baume, the lighter portions lieing too unstable for an accurate .statement owing to their tendency to change from a liquid to a gaseous condition upon a slight rise in the 756 MINKS AND QUAKRIES. temperature or a fall in the barometer. The gravities of retined oil distillates range from 50- to -ii ' Baumc; that of residuum from 25^ to 15''. There is usually left in the l)ottom of the still, after the li(iuid is drawn off, from 1 to 1.5 per cent of the original charge. This reuiains in the form of a compact cellular solid, known as ''coke," which is almost pure carl ton, and which is usually disposed of to parties who manufacture carlion pencils for electric arc lights. During the process of distillation the proportion of these products is varied, to meet the demand of the market, by prolonging or shortening the intervals of cutting ofl' from one variety and beginning on the other. The lighter products are alwaj'S the first to condense, then come those with an average density, and the heaviest last. The quality of a portion of the petroleum produced in Kansas and Indian Territory in many respects re- sembles Pennsylvania petroleum, although the gravity is lower. Separated l)y intervals of dry or undeveloped territory, there are a number of productive pools, which jdeld petroleum of a gravity varying from 36- to ^8- Baume, although there is a considerable portion as heav^' as 18^ to 20-". Nearly the entire production of the lighter grades is sold to the refineries at Neodesha, where an excellent water-white illuminating petroleum is manufactured. Ill these fields the lighter products amount to about 45 i^er cent of the total yield. A considerable portion of the heavier products is marketed as a gas enricher or as a fuel oil. The following may be taken as a fair average of the products secured from the petroleum of 36'- Baume in the Kansas field: Average produrls from jielrtilcnni produced in the Kanianjii'/il : 190l'.

In the year 1902 about 96 per cent of the Texas production was an inferior grade of petroleum, containing 1.1 to 1.8 per cent of sulphur, and having a specific gravity of nearly 0.92, equal to 2l'- Baume. This is satisfac- tory as a fuel product, and a very large part of it is consumed as such. A comparatively small yield of the lighter products is secured in refining. According to Prof. ('. A. Maliery, at from 145- to 200- only 4 per cent passed over as naphtha at 46- Baumi^, or 0.7954 .specific gravity: and at from 2()0 to 250- onlv 11 per cent pa.ssed over at 35- Baume. equal to 0.84S1 specific gravity.

In some analyses the sulphur in the Beaumont petro- leum is placed as high as 2 per cent. For the most part, however, it is not combined chemically, Init is merely dissolved, and can, therefore, be more easily separated than that found in the Lima-Indiaiui petro- leum. Wj'oming produced comparatively an insignihciuit Cjuantity of a very high-grade lu))ricating petroleum, which is partially distilled and filtered under pressure before it is put upon the market. There are a number of grades of crude petroleum produced in California, ranging from natural naphtha, with a specific gravity of 66"^ Baume, to heavy black tar, with a gravity as low as 11'- Baume. About 80 per cent is made up of the very hetivv petro- leum which finds a market principally as fuel. The por- tion that is refined does not produce such light products as the eastern oils; they are all heavier, as they have a larger proportion of carbon to that of hydrogen in their composition. Largely for the same reason, they do not have the same illuminating effect when burned in the ordinary lamp. To make them acceptable as illuminat- ing oils they are often mixed with the eastern products.

Thi' calorip'c value of j>etr(ilci(iii . — The calorific or heat producing pi'operties of i)etroleuni are measured by the pounds of water that a given weight will evap- oi'ate at a temperature of 212 ' F. when there is no heat lost. It has also ))een determined that the heating- energy necessarj' to evaporate 1 pound of water at 212- F. would raise the temperature of OtiO pounds of water 1- F. The unit used is the heat necessary to raise the temperature of 1 pound of pure water 1- F. at or near 31M''-- F., which is known as the British ther- mal unit, generally expressed as " B. T. C" The French thermal unit, the "calorie," is that quantity of heat required to raise the temperature of 1 kilogram (2.20H3 pounds) of water 1 - C. The • ' B. T. U. ." there- fore, is equal to 0.252 calorie. The "■ pound calorie'" is sometimes used by English engineers; it is the quantity of heat necessary to raise the temperature of 1 p;.>uiid of pure water 1 ' C. ; 1 pound calorie equals nine-fifths "B. T. U.," or 0.1536 calorie. It is remarkable that petroleums of difi'erent specific gravity and chemical composition, and coming from widely separated localities and countries, have calorific values so nearly e(|ual, as indictited by the number of pounds of water theoretically and actually evaporated per pound of petr<.)leum consumed. In gi\ing the test of boilers, under the head of actual pounds of water evaporated at and above 212- F. , they are often credited with the results of special tests made when the boilers and the surrounding appliances were in perfect con- dition; therefore, in practice, the results will in many cases l)e lower than the figur(\s (pi(.)ted. 758 MINE8 AND QUARRIES.

Lupiijl fu(fl foi' iiiiiriiir 2)iirji(i.s, .s. — The development in the last two years in Texas, [.louisiana, and Ciilifornia of large fields of petroleum specially adapted for fuel, with the profiabilities of increased production in these localities in the near future, has added to the interest felt in the practical solution of the fuel prol)lem. The possibility of the successful and economical use of liquid petr(.)leurn in the Soutliwest ;ind West has bc'en fully demonstrated in its application to locomotives and stationary engine.s, as well as to a vast number of manufactories that require a large supply of fuel. In eastern Europe and southern Asia, along the path of the great ocean commerce and on the waters of the Black and Caspian seas, its use is increasing. Russia and Borneo, and, to a less extent, Sumatra and Java, furnish the liquid fuel in these far-otf countries. At Singapore a central supply depot of considerable magnitude has l)een established within the last few years. There are smaller supplies stored at Suez, Bombaj', Calcutta, Hongkong, and Yokohama. There are a number of large steamers employed on the Gulf of Mexico and the Pacific coast, some of which have used liquid fuel for a luimber of years and have fully demonstrated its superiority. The numVier of petroleum liurning steamers is rapidlv increasing. The utilization of the entire energy in petroleum will be accomplished only when it is mixed with the atmos- phere under high pressure and exploded in the cylinder direct, in which case the costly, troublesome, and waste- ful boiler will no longer be necessary. During the year 19(>2 the U. S. Navy made some very interesting experiments with petroleum as a fuel, which were conducted by a special division of the Bureau of Steam Engineering known as the Liquid Fuel board, under the direction of Rear-Admiral George W. ]Mel- ville, Chief Engineer V . S. Navy.

There is also a lai'ge amount of luliricating oil man- ufactured from Peimsyh'iiiiia crude petroleum, some of wdiich is mixed with the natural product. No other lubricitting petroleum is equal to that produced in the Appttlitchian field. Its reputation is \vorld wide. Many railroads and steamship lines use it e\clusi\'ely; the railroads using it in the I'nitetl States operate iJT per cent of the total mih>age. Nearly 2,()U(.),U0U barrels were exported in liMl'J. PETROLEUM. 759 Early developinent of jydrolenm in the ZTntti'd StatcK. — Years ao-o the process of distilling natural mineral h^-dro- carbons was being perfected and vigorously pushed in tlu' Eastern states, and cannel shale was iinport(>d from England and distilled at retincrics near Boston and Port- land. On the Allegheny river near Ereeport, Arm- strong eouuty and Darlington, Heaver county. Pa.; in Ohio, AA'est Virginia, western Kentucky, and elsewhei'e in this country and in Europe, there were refineries or distilling plants endeavoring to supply the demand for an efficient and cheaper lighting oil. The high price, how- ever, prevented its universal introduction. The tallow candle was almost the universal source of artificial liglit before the great natural deposits of petroleum were known. The earliest records of the travelers who first pene- trated the wilderness of southwestern New York, north- western Pennsylvania, southeastern Ohio, and south central Kentucky mention the existence of petroleum and natural gas; and the early explorers were guided to these localities by the Indians, who regarded the phenomena with religious superstition. On Oil creek, Pa., there were a number of localities where globules of petroleum and bubbles of natural gas constantly came to the surface of the water. The remains of pits that were cribbed in a crude manner were noted by the early explorers in numerous localities, extending irom the mouth of Oil creek to Titusville. Erom 1^48 to 1856 Mr. Sanuiel M. Kier, of Tarentum, Pa., bottled the petroleum oljfained from his salt w(dl and sold it under the name of "Seneca oil," wliich name it acquired from the Seneca Indians in New York state, who were early acquainted with its medicinal virtues. The partial refining of the petroleum found in the salt-brine wells at Tarentum was accomplished by ^Ir. Kier about the year 1857. Owing to the rude method of refining and the poorly constructed lamps of that da_y there were many bitter complaints of the odor and smoke of the new illuminating oil when it was first tried. During the years 1853 to I860 there were four large plants erected near Ereeport, Pii., on the Allegheny river, near the mouth of the Kiskiminitas river, for the distillation of a cannel slate, which in this locality varies from 2^ to 7 feet in thickness and forms the roof of the lower Ereeport coal strata. In 1856. after many failures, a j^lant at Ereeport suc- ceeded in producing an oil that burned with a bright light and was free from odor and smoke. Its introduc- tion was accompanied with difficulty, owing to the dangerous and highly explosive " burning fluid " that was at that time in use. At this period there were also cannel coal distilling plants at Darlington, Beaver county. Pa., Canfield, Mahoning county, Ohio, Cannel- ton, W. Va. , and Cloverport and Maysville, Ky. In Massachusetts parties who had formerly been eugaged in the manufacture of whale oil conunencecl to manu- facture a paraffin oil from cannel slate (called boghead mineral) imported from Scotland. About this time small quantifiers of petroleum were collected )iy Mr. J. D. iVngier, on an island near the mouth of Pin(j creek on Oil creek, Pa., al;)out 1^- miles below Titusville, from pits ari'angcd one abo\'e the other, and by others who used blankets and tcnqjorary dams. On the 30th day of December, 1.S54, the Pennsylva- nia Rock Oil Company was organized, based upon the pur(diase of 105 acres at the junction of Oil and Pine creeks, near Titusville. Pa., anse wei-e loaded at Oil City and tl(jated down the river to the refineries at Freeport. Pittsburg, Rochester, ]\Iingo, Wheeling, ^Marietta, and Parkersburg. The latter points also received crude petroleum transported in Inilk boats from Burning- Springs on the Little Kanawha riAcr. AVhen there was water enough in the Allegheny river these empty bulk boats and fiats were towed upstream b.y steam towboats; at times of low water they were towed up by hors(\s. Though these im])rovements in transportation, both by rail and by Ijoat, i-emo\-ed a part of the difficulty, there yet remained the obstacles that were experienced in mo\ing the crude petroleum from the wells to the railroad or i-iver. This was still done liy team, and the roads were often almost impassable on account of the PETROLEUM. 761 depth of the mud; the method was at best expensive, and accompanied by great hardship to man and beast. It was chieii};' this condition which restricted the amount of petroleum that could be put upon the market. This condition of ati'airs suggested the tirst pipe line. The first one that was a success was constructed bj' Mr. Daniel Van Syckle, of Titusvillc. Pa., in the sununer of 1S65, extending from Pithole to the railroad at the Miller farm, on Oil creek, a distance of 4 miles. In the fall of the same year, Henry Harley constructed a pipe line from Benninghofl' run to the Shaffer farm. The origi- nal line built by Van Syckle was purchased ]jy the lirm of Abbot & Harlej', who united the two under the name of the Allegheny Transportation Compan3^ Both of these lines were successful, much to the discomfiture of the teamsters and roustabouts, who, in some in- stances, interfered with the operation of the line bj^ cutting or pulling it in two with their teams. A num- ber of arrests followed, and from then on the pipe line was an accomplished fact and an important factor in the collection and deliyerj' of petroleum to points where it could be loaded i n tank cars or bulk boats. The growth of long pipe lines was gradual, and it was several years before it was practically demonstrated that long lines could be successful!}' operated. The improvement in railway transportation by the introduction of the iron tank car was a decided advance over the wooden tanks set in box and flat cars, which for a time answered all the requirements. The tanks at the wells are connected by a system of small lines or veins which feed the main lines or arter- ies. These smaller lines usually are concentrated at the lowest portions of the field drained at points known as local pumping stations. A considerable proportion of the oil finds its w'ay into the tanks at these stations by gravitj' and is forced to the large receiving tanks at the main station by pumps, which are often driven by natural gas engines, or it flows by gravity through suc- tion lines to pumps into pits and is then elevated to receiving tanks. From the large receiving tanks the jjetroleum is forced into the main lines at a pressure often of between 600 and 900 pounds to the square inch. These massive pumps generally represent the highest known mechanical efliciency, having triple expansion engines, Corliss valves, condensers, air pumps, and cflicient boilers. They usually develop 300 to 400 horsepower and handle from 30,000 to 35,000 barrels in twenty-four hours. The boilers are economical and properly proportioned to this work, showing a duty of 16 pounds of water evaporated at and above 212- F. per pound of crude petroleum consumed as fuel. One pound of good coal will evai^orate 10 pounds of water, and 1 pound of natural gas (equal to 20 cubic feet) will evaporate 20 pounds of water under the same conditions. The main pumping plants are placed from 30 to .50 miles apart, according to the elevation of summits that nuist be overcome; and by the addition of a parallel line, or loop lines, for a portion of the way the distance can be increased so as to reach localities convenient for fuel or water without greater tax upon the pumps. There are probably 4,600 miles of main trunk line, from 4 to 8 inches in diameter, in the Appalachian and the Lima-Indiana fields, reaching fi'om northern Ten- nessee to Parkersburg, Cleveland, Buffalo, Franklin, Olean, and to the seaport cities of New York, Philadel- phia, and Baltimore. From the Lima-Indiana held the main lines reach westward to Chicago, Montpelier, Toledo, Lima, and eastward it connects with the Appa- lachian system. Kansas has an extensive system of main lines and local lines, reaching in several directions from Neodesha. In California a main line was recently completed, reach- ing from Bakerstield to a refinery at Point Richmond, near San Francisco, and having a branch line to Coa- linga. The length of this main line is 278 miles, and it is connected near its starting point with about 160 tanks holding 35,000 barrels each. There are other smaller lines in California, extending from Pico canyon to Ventura and connecting Fullerton with Los Angeles. Texas has in the last two j^ears greatlj^ increased its mileage of main line. There are four lines from 22 to 30 miles in length, reaching from the original held near Beaumont to tide water on the Gulf, and connecting it with Port Arthur and Sabine Pass. Sour Lake and Saratoga are also connected by pipe lines with Beau- mont. The Corsicana field in the northeastern part of the state is connected by pipe lines with the refinery there. The length of the entire sj'stem of main lines in use in the United States in 1902 was apjDroximately 7,S0() miles, a large portion of which is double and triple lines, to which may be added 50,000 miles of smaller lines connecting the 51,774 tanks of the pro- ducing wells with the iron tanks of the receiving and transporting companies. As earlj^ as 1875 organizations were effected and charters secured for the privilege of building pipe lines to the seaboard. However, these chartered companies at that time confined their operations to the oil regions, where they built numerous lines, usually of a 2-inch diameter, to the several railroads and their branches and to the nearljy refineries. The competition among these new pipe line companies for securing the produc- tion of the fields began to be marked, especially in But- ler county, Pa., and rates for delivery were cut to such an extent that the lines were in several instances oper- ated at a loss. The demand for a consolidation of these competitive conqianies became more and more emphatic. Under the title of the Fairview Pipe I^ine a company was organized by Capt. J. J. Vandergrift and George V. Foreman, under the laws of Pennsylvania, the act bearing date of April, 1874. This company was after- wards known as the United Pipe Line Association. Into it was merged, from time to time, the other local 762 MINES AND QUARRIP]S. lines until it controlled almost the entire system. Gradually the temporary and uncertain characteristics of pipe line transportation disappeared, and more per- manent structures were built. The first trunk line, constructed in 1875, was 3i) miles long and built of i-inch pipe, now removed. It started at Carbon Center, .5 miles east of the town of Butler, Butler county. Pa., and extended to Brilliant, a suburb of Pittsburg. The trunk line to Cleveland, Ohio, was completed in the summer of 1879. This was a 5-inch line, beginning at Ililliard station, in the northern por- tion of Butler county, 8 miles west of Bear Creek sta- tion, and extending 103 miles to Cleveland, Ohio, where it supplied the refineries that had formerly received their crude petroleum by tank cars. There were relay stations on this line at intervals of 25 to 30 miles. During the same year other shorter lines were laid in the Bradford lield, reaching the Erie Railroad at Car- rollton and Olean on the north and the Pennsyh'ania Railroad at Kane on the south. In the winter of 1879 and 1880 the first trunk tines to the seaboard were begun. The one in Pennsylvania, which was built of 6-inch pipe, started at Colegrove, in ^NIcKean county, and extended to Philadelphia, a distance of 235 miles; a 5-inch branch line left the main line at Milhvay and extended 66 miles to Baltimore, Md. The other sea- board lines started at Olean, N. Y., and were laid double; there were two 6-inch lines, running paralld through the southern counties of New York to Saddle River, N. .7., where thej' separated, one terminating at the Bayonne refineries in New Jersey, the other passing on, under the North and East rivers, to the refineries located at Hunters Point, on Long Island. The distance between the points named was about 313 miles; the length of the pipe recjuired bj^ reason of loo})s. etc., was 762 u:iles. Olean was shortly afterwards con- nected In' pipe line with Beai' Creek station, on the Allegheny river, near Parker. Pa., making a ccjntinu- ous line to Baj-oime, N. J., a distance of 420 miles. The southern trunk line, which begins at Morgantown, W. Va., extends across nearly the whole length of the state to Philadelphia, a distance of 271 miles; it was completed in 1890. The cheap and efticient method of transportation by trunk pipe lines, permitting the crude and refined petro- leum to be delivered at seaboard at a cost nuich less than it was possible for it to be transported by rail or canal, marked an important era in the histor}- of the petroleum industrv. jVIany problems had to be soh^ed in the con- struction of the first pipe line. The question of the proper selection of pipes and the making of pipe joints that would not leak under the great pressure; the manner of carrying pipe lines across large streams and rivers and overhigh, steep hills; the selection of proper locali- ties for tanks and i)nmp stations; the selecti(jn of pumps; the cleaning of tlic pi|)cs when foul; and tlie method of equalizing distance betwctMi punij) stations, ]>v (he doubling of a portion of the line, so as to equalize the work on the pumps at each station, were all new condi- tions and demanded the highest mechanical and engi- neering skill in order to overcome them. These diffi- culties were all surmounted in a comparatively short time. The transportation annually of 10,000,000 tons of petroleum an average distance of 380 miles by pipe lines, with only insignificant loss by leakage, evapora- tion, or tire, represents a triumph of the highest engi- neering and mechanical skill. The introduction of the pipe line system brought about the removal of the re- fining branch of the petroleum industrv to the centers of manufacture in the lake and seaboard cities, where at least 80 per cent of the crude product is now con- verted into illuminating oils and other merchantable commodities. Great numbers of the small refineries, that were formerly scattered over western New York, western Pennsylvania, AVest Virginia, and southeastern Ohio, have disappeared, and the business of refining oil has been transferred to the immense refining plants near New York. Philadelphia, Baltimore, Cleveland, Buffalo, and Whiting, Ind.: Port Arthur, Tex.; and Point Richmonfl, Cal. From these great industrial cen- ters the niaiuifactured ])etroleum finds its way to the markets of the world by ocean tank steamers, or lij- the bulk carriers of our inland lakes, or it is distrib- uted by rail in tank cars to the consumers who can not 1)6 reached liy these more econoniical methods of trans- portation. The important inland I'efineries remaining are located at Olean, N. Y.; Titusville, Oil City, Frank- lin. Warren, and Pittsburg, Pa.; Parkersburg, W. Va. ; Lima, Ohio; Neodesha, Ivans.; Corsicana, Tex., and Florence, Colorado. The pipe line companies for many years have been the purchasers of the crude petroleum in the older fields. The pipe line company, upon application from the producer, sends an agent, generally known as a gauger, to measure and inspect the petroleum in his tank and run it into its lines. The tanks throughout the Held are carefully measured and numbered, and when the oil is ai'Ct'pted and run into the taidvs of the pipe line company a card is issued showing the number of barrels to the credit of the producer. E\'ery tank is carefully gauged and numbered and a table prepared, which shows the number of barrels it con- tains for e\'ery inch of licpiid from top to bottom. The temperature of the crude petroleum is also recorded and the contents of the tank examined for water. After measuring the ]>etroleum the gauger gives the operator what is known as a. "run ticket," keeping a copy for himself. The i)ipe line company deducts the royalty due the t)wner of the property according to the terms of an agreemenl on file at the office, and the next day the producer may secure the cash for his petroleum at tlie market quotation for the day or hour of his sale at the nearest home office of the companv- PETROLEUM. 763 If the producer wishes, he can secure a certificate when \ subject to a charge of one-twentieth of 1 per cent daily his production in the tanks of tlie pipe line couipaiij' j thereafter until exchang-ed. To co\'er losses by fire or amounts to l,iiO() barrels. These jiipe line certificates ' lightning, certificates are subject to an assessment pro are made payal:)le to bearer and are therefore ti-ansfer- I rata on all oil in custody of the pipe line. Xono of able. They are subject to transportation charge in the district of i!o cents per l)arrel, and to a charge for stoi-age at the rate of 25 cents per day per l,0i)O barrels when the price is less than ^1; 30 cents when over $i and under $1.50; and 40 cents for all ()v<'r $1.50 per barrel. They are to lie returned for exchange to the pipe line company within six months after issue, being these charges are included in the prices as (juoted and which arc the prices at or near the wells. T(^ these pi'ices, when the oil is delivered to the refineries, charges are added for storage and transportation. It was upon these certificates that the speculative business at the exchanges at New York, Bradford, Titusville, Oil Citv, and Pittsburg was based. Table iC— DETAILED SUMMARY: 11)02. UniU'd ■ States.

NATURAL GAS (765) NATURAL GAS. Bv F. H. Olipiiant. The existence of natural gas. in greater or less quaii- tit_y, accompanying petroleum, has })ecii known since the early development of that industry, heginning with 1859. The introduction of this gas, tirst as a fuel and light, afterwards as a source of power, was slow. The dou1)t concerning the duration of the supply, the lack of appreciation of its value as a fuel, and the uncer- tainty as to transportation contributed laigel\ to post- pone its general use. The subsequent demonstration that it existed in large tiuantities in natural reser- voirs, that it could be conveyed etticiently in pipe lines, and that it was of great utility as a fuel caused a re- markable increase in its consiuiiption. and natural gas soon became one of the most valualde of mineral pro- ductions. Although used extensively as far back as 1883, it was not regarded as of sufficient commercial value to warrant statistical consideration until during the decade ending with 189b. The reports of the Eleventh Census are the first in which this industry is presented. The statistics for 1902 and 1889 are summarized in the following table: Table 1. — ConipuraUre summary: lHai find 1SS9.

The number of wells producing at the close of Decem- ber, 1889, was given as 3,247, and the amount received for the gas consumed was $11,<>4:1:,S5S. The value of the fuel displaced was computed at $31,097,099, includ- ing that displaced by gas used at oil pipe line stations, in pumping and drilling oil wells, and for other pur- poses. This was regarded as the actual value. The value given for 1902 is the amount received from the sale of the gas. The quantity and \'alue of petroleum produced from natural gas wells are included in the statistics for petroleum, but the statistics pertaining to wages, emplo3'ees, and other expenses are included under natural gas. During 1902, 15,800 wells were operated; of this num- ber, 1,250 were abandoned duiing the year, leaving 11,550 that were productive at the close of the year. These 11.55(1 wells produced natural gas valued on an average at ^2,117 for each well. During the year 1889 the output of the 2,247 wells producing natural gas was valued at $4,915 per well. As a result of the severe competition in the marketing of natural gas during 1889 and the large outlay caused by the drilling of numerous wells and the construction of a number of pipe lines, the expenses wei'e $3,876,028 greater than the amount received from the sale of the natural gas produced in that year. The quantity of natural gas marketed during 1902 is estimated to have been 205, 784,453, 333 cubic feet, which was sold at an average price of 15 cents per l,, KKCORO OK WKLLS, AND LENGTH OF PIPK LAID, BY STATES: 1902.

The l)est paid wage-earners were those classified as machinists, blacksmiths, car- penters, and other mechanics. These are intrusted with manipulation of the wells, drips, and pipe lines in the field, and have charge of the lines and regulators in the cities and towns. Although the work is not often laborious, it requires good judgment and special training to deal successfully with the various condi- tions that require personal attention. The employees clas.sified under the head of "all other wage-earners" include line Avalkers, regulator watchmen, men who relieve the wells and drips of salt water, men who carry out instructions as to the regulation of pressure on the main lines by opening or closing the gates at 3022,3—04 49 the wells, and men engaged in pulling out wells and retubing them as exigencies may rccpiire. ('(infract iriirk. — Besides these wage-earners an aver- age of 3,2tl,S workmen wei'e employed as rig builders, drillers, and helpers, and were paid by contractors for drilling wells. This number, added to the 4,678 wage- earners in the regular emyjloy of the natural gas com- panies, increases tlie numbei' of wage-eariiei's emplo3'ed in the natural gas industry to 7,946. The workmen employed by the contractors in building rigs and in drilling wells are specialists and are usually men of more than ordinary ability and bodil}' strength. Their wages are high, ranging from %?> to $4. .50 per day; their total earnings, however, are not great Ijecause of the time lost in moving from one location to another, which occurs fre(;[uently, as a well is completed usuall_y in from twenty to forty days. The contrat'tors are generally paid by the foot. The price varies greatly because of the differences in the depth of the wells and the character of the strata passed through, and the number of different .sizes of casing required to complete the well, which may vary from 1,000 to 2,500 feet in depth to the gas sand. Where only a single string of 5#-inch casing is used, the price averages about forty-five cents per foot; where two strings of casing are required, the price per foot will average 75 cents. In the deep holes in southern Penn- sylvania and West Virginia, where three and in some cases four strings of casing are required to complete a deep well, the price ranges from ^1.20 to fl.60 per foot. The rig, or derrick, and the casing are generally furnished l>y the natural gas company, the contractor supplying everything else that is necessary to complete the well, and receiving pay only in ease the well is turned over to the gas company in perfect condition. The plugging or loss of a well before it is completed falls upon the contractor. Sii]:)pl'uiH^ mater/ah^ and inlxcellanediiH exjjenses. — The miscellaneous expenses, which amounted to $5,912,257, were made up of rents, royalties, taxes, insurance, and sundry expenses. The cost of supplies and materials amounted to $6,6o7,255, and included the cost of pipe, casing, tubing, engines, boilers, pumps, drips, regula- tors, and sundry other items necessary for the deliver}' of the natural gas to the jjoints of consiuiiption. Mcchnnical pmrer. — The total primary power em- ploj'ed in 19(.»2 aggregated I(i4,ln7 horsepower. This was used to free the gas wells of water and to compress the gas so that it could be transported in sufficient quan- tity to the place where the original pressure had de- creased. Of thishorsepower94,595, or 90. 9 percent, was generated bv steam; 7,083, or 6.8 per cent, was supplied b3'gas or gasoline engines; and 2,162, or2.1 per cent, was furnished by other prime motors. The rented horse- power was two-tenths of 1 ])er cent of the total, the amount being 267 horsepower; of this, 225 horsepower. 770 MINES AND QUARRIES. 01- 84.3 per cent, was electric. In addition electric motors, having a total capacity of .50 horsepower, were owned. Production. — It is estimated that the United States produced over 98 per cent of the world's output of natural gas in 1902. Canada produced 1.2 per cent, and the rest of the world the remaining eight-tenths of 1 per cent. The total value of the production of natu- ral gas in the United States for 1902 was $30,867,863. This is the largest value thus far recorded in the his- tory of the industry, and is equal to 13.2 per cent of the value of the petroleum produced in the same year. The following table, compiled from the published reports of the United States Geological Survev. shows the production of natural gas from 1872 to 19()2: Table 0. — T''(//((' <;/" jirodnctlon of untural //as: 1S7..'

If it be assuQied that an average of 7 cents per 1,()00 cubic feet was the price of natural gas from tlie time it was first introduced in 1872 until the dose of 1902, the total valueof the product for those years — §317, 7.57,731 — would indicate a voluaie of i, 539, 396, 159, 000 cubic feet. If it were possible to confine this immense quantity of natural gas in a tank whose section was 1 square mile, and if the density would remain the same throughout, it would require a tank 30.8 miles long; or it would till a pipe having a diameter of 67i feet encircling tlie globe. This quantity represents a fuel value equal to 226,969,800 short tons of coal. Large as this quantity of natural gas may seem, it probably does not represent more than one-half of the amount that has been taken from the original reservoirs. The early and even more recent development was accompanied by profligate waste, and large quantities were also lost during the development of the numerous petroleum fields, as many of the rocks above the petro- leum strata, when pierced by the drill, were found to contain great (Quantities of natural gas, which was allowed to flow into the air until it was exhausted. In the early development of some of the largest fields many of the first wells, when the pres.sure was greatest, were permitted to discharge immense quantities into the atmosphere for months and years. Torches and escape pipes were allowed to consume and blow off great quan- tities. There seemed to be a general impression that these great reservoirs of natural gas were practically inexhaustible. The methods employed in applying the gas in mills and factories, and also in domestic service, were wasteful in the extreme. For many years the natural gas companies allowed their customers to con- .sume any quantity that would pass through a certain sized orifice. The mills and factories usuallv paid according to the amount of finished product, using the gas as they saw fit, which was often in the most crude and extravagant manner. In a measure this condition was brought about by a number of companies owning wells in the same field over which the declining pressure adjusted itself. When the pressure began to decline each owner made an attempt to realize the greatest revenue before the field became exhausted to such an extent that his pipes could not deliver sufficient natural gas to cause the returns to be profitable. It has been estimated that since the beginning of the industry the greatest quantity of natural gas was con- sumed in 1888. This quantity, estimated to have been not less than 750,000.000,000 cubic feet, was partly util- ized and partly wasted. It is estimated that it dis- placed fuel to the value of $22,629,875, which gives an average of 3 cents per 1,000 cubic feet. Because of the nature, occurrence, and uses of nat- ural gas, it is ii very difficult task to ascertain the exact value and (|uantity consunnMl; every efi'ort, however, has been made to secure these totals, and each succeed- ing year the records have ))cen nearer the true amount, and the quantity unreported has gradually liecome less. The following table gives the value of the natural gas produced and the value of that consumed in the United States from 1899 to 1902, by states: NATURAL GAS. Table 7.— VALUE OF NATURAL \ the outburst of imprisoned natural gas when their crude drills penetrated the sealed- in reservoirs. These outbursts were often of sufficient violence to blow out the drilling tools, and in some instances they ignited and destroyed the primitive drilling plant. In subsequent years the search for petroleum devel- oped many pools of natural gas of high pressure, and in the early development of petroleum the finding of this gas was considered a dangerous and unwelcome discovery, although it was known and utilized in a few localities long before the first well was drilled for pe- troleum in 1859. Natural gas has been developed almost entirely in the northeastern portion of the United States, there being only a few wells, comparatively, in the west and south- west portions. In Canada some has been found, a part of which has been consumed in the United States. Although natural gas is distributed largelj' over the entire globe, its development and use outside of the United States and Canada has been insignificant. There is at present a small consumption of natural gas in Eng- land, in Sussex count}'. Holland makes use of it for the partial illumination of two small villages on the Zuyder Zee. Galicia, Roumania, Russia, India, Persia, and Japan use it in a limited way in the operation of petroleum wells and in refineries. One of the most noted natural gas vents or springs located by the pioneers was on the northern bank of the Kanawha river, in West Virginia; this spring was visited in 1776 by General Washington, who was greatly impressed b}^ the phenomenon. There was also a well- known gas spring on the Big Sandy river 60 miles above its mouth; and numerous springs w'ere known to exist on what has been called the St. Marys uplift, which extends 25 miles north from Burning Springs on the Little Kanawha river. In the early history wells drilled for salt water in the area extending from the Cumberland river, K3'., to above the mouth of the Kiskiminitas on the Allegheny river, ver}' often de- veloped large flows of natural gas. In some cases the flow of these wells was persistent, in other cases it was soon exhausted. The earliest economic use of natural gas in this coun- try was, in all probability, in 1821, when it was used in the lighting of the village of Fredonia, Chautauqua county, N. Y. On the banks of the Canadaway creek, on which Fredonia is situated, a well li inches in diam- eter was drilled to a depth of 27 feet, and from this was obtained a flow of natural gas sufficient for 30 burners, the light of each of which was considered to be equal to that of two good candles. Several years later, in 1825, a small gasometer was introduced, and afterwai'ds a number of shallow wells were drilled, and from these more or less natural gas was secured. In 1871 a well developed a very large flow of natural gas when at the depth of 1,200 feet it pierced the Corniferous limestone. A well dug for water at Findlay, Ohio, in 1838 pro- duced large quantities of natural gas near the crest of the great Cincinnati uplift. The gas was collected and convej'ed into the house of Mr. Daniel Fostei', where it was utilized for nearly fifty years, until the regular development of the great Findlay gas field began in November, 1884. In 1811 natural gas was developed in association with salt brine in a well drilled on the Kanawha river in W^est Virginia, near where an original gas spring was located. The pressure was sufficient to force the salt brine up into a large hogshead where the salt and gas were separated. The salt brine was diverted into salt pans and the gas conducted to the furnaces under- neath, where it was successfully used as fuel for the evaporation of the salt water. More or less gas was developed on Oil creek. Pa., and in the surrounding section, by the wells drilled in the search for petroleum in the winter of 1859 and 1860. Some of these wells produced gas only, and others pro- duced both gas and petroleum. For several years it was the common practice to conduct the gas to a safe distance and there consume it to get it out of the waJ^ The high price of coal and wood and the extremely poor roads, finally induced some of the more venture- some to try to burn it under boilers. This experiment was so great a success that natural gas became a most efficient substitute for coal and wood. In its early application, however, numerous fires and ex^Dlosions were caused by overpressure, because at that time no automatic method of regulating the pressure was known. One of the first applications of natural gas for fuel purposes was in the year 1868. when a manufacturing company in Erie, Pa., drilled a well 600 feet deep into the Devonian shale. This well produced a considerable amount of gas when first opened, but the output gradu- ally declined. Many wells that were sufficiently large to supply one or two dwellings were afterwards drilled in this locality. Near Titusvillc, Pa., in 1872, thirteen years after the drilling of the first oil well, a powerful natural gas well was drilled on the Newton farm, 5i' miles north of the town. The gas from this well was conveyed into the town by a 2-inch gas main, which furnished 250 774 MINES AND QUARRIES. consumers witli light and fuel. Afterwards the origi- nal line was reinforced by a second one 3i inches in diameter. The two lines maintained a stead}' pressure and a satisfactor}' supph'. This was the first natuial gas plant Avhich supplied light and heat in an}' large and permanent quantity by methods and aj^pliances similar to those in use to-day. It is looked upon as the beginning of the industry which has since assumed such large proportions. During the year 1873 natural gas was successfully introduced for fuel and light at numerous localities in Venango, Butler, and Armstrong counties. It was also introduced at Leechburg, in Armstrong county, in the same year, the supply being obtained from an aban- doned well drilled for oil in 1871, and was successfully applied in heating and puddling furnaces. Iron mills at Etna, near Pittsburg, Pa., were the first large mills to be supplied by a gas line of any consider- able length. The supply was used for years. This line was built in 1875, and extended from the iron mills to the Harvey well, near Lardens mills in Butler county, a distance of 17 miles. This well was one of the largest known at that time. By the close of 1883 several pipe lines were supply- ing the manufacturing establishments and the domes- tic service in Pittsburg, Pa., the supply being from the Murrysville pool, in Westmoreland county, which had been developed several years previously. In 188.5 the Grapeville and the Speechley pools were first developed. The increase in its use was remarkal)le, and a number of pools in Washington, Butler, and Beaver counties were opened up and connected ])y pipe lines. In 1886 the gas field at Findlay, Ohio, began to be prominent. Afterwards a large field in Indiana was developed. The development of these large reservoirs of natural gas, hitherto unknown, seemed to impress the general public and many of the operators of natural gas fields with the idea that these reservoirs were practically inexhaustible. The fact that the cjuantity of gas withdrawn from any of the large fields by one or two wells decreases the vol- ume and pressure very slowly caused a false impres- sion as to the extent of tlie reservoirs. As the fields were developed, howe\'cr, and many wells reached the gas reservoirs, the decline in the pressure became more rapid and noticeable. In Pennsylvania, Ohio, and Indiana inuuense: (juan- tities of gas were consumed in wasteful and extravagant display, which in numerous instances almost turned night into day. This extravagance was not realized until the fields began to lie seriously depleted. In the mills and factories IIk; application of gas as a fuel was made in a wasteful and unscientific manner; at least double the quantity of gas necessary to do a given amount of work was consumed. In 1890 and 1891 man}' reforms tending to improve methods of storing, ti'ansporting, and consinning natu- ral gas were inaugurated. The meter was introduced, which at once made it to the interest of the consumer to see that consumption was economical. The wells were controlled from the head office by telephones, so that when the supply was more than enough the gates at the wells were shut. The wells were watched more vigilantly, salt water was kept out with more care, and leaks and joints and all pipe connections were carefully examined and repaired. The use of large pipes by many of the gas companies began altout this time, enabling them to send larger quantities to points of consumption at reduced pressure. Zhe-'<. — Natural gas is used principally as a sovu'ce of light and heat in domestic service. It is employed extensively in industrial establishments for many pur- poses, notably in the manufacture of glass, in the gen- eration of steam, puddling of iron, in roasting ores, in heating furnaces, and in the manufacture of steel, and it is also utilized as a source of power in the gas engine, in drilling and operating oil and gas wells, and in pumping oil. The heat value stored in natural gas is greater than that caused by any artificial combination of carbon and hydrogen, and is a perfect fuel as it issues from its original rock-sealed reservoirs. No preparation is necessary for its combustion and no resi- due is left. It is not afi'ectcd by ordinary temperature and it is easily distrii)uted by pipes to points of con- sumption. It is a most economical source of light and power, and an ideal household fuel. The illuminating properties of natural gas vary in different localities, because of the difference in the per- centage of the heavier hydrocarbon, ethane (C.H,/). All the natural gas found adjacent to petroleum fields has a larger propoi'tion of ethane than the gas farther re- moved, and therefore the candlepower is consideraljly greater. Ordinary natural gas, if consumed with a common tip at the rate of 7 or 8 cubic feet per hour, will yield about H or 7 candlepower. In an ordinary Argand burner with chinmey, it will give about 13 candlepower in consuming 5 to 6 cubic feet per hour. AVhen natural gas is consumed in contact with a mantle of alkaline earth (thoria, etc.). the result is the cheapest and best illuminant known. AA'hen the price of natural gas is 25 cents per 1,()IH) cul)ic feet, and 50 candlepower is obtained from a consumption of '■2^ cubic feet per hour, the cost per candlepower per hour is only 0.00125 of a cent. There were 51(i,00O domestic consumers of natural gas during 1902, and it is estimated that in the western portions of New York and Pennsylvania, in central and western West Virginia, and in Ohio, Indiana, and Kan- sas, not less than 4,r)(H),0(H» persons received the benefit of natural gas used as a. fuel and an illuminant. Over 8,000 mamifacturing establishments were also supplied. The introduction of natural gas into the household, for which it is eminently fitted, has been accomplished -without personal inconvenience or loss of life, except in very rare cases. The risk from fire is less than when wood and coal are used. There have been some cases of asphyxiation when a stove has been burned in a room without a fine connection, as it has lieen found l.)v NATURAL (iAS. 775 experiment that combustion under these conditions is imperfect, especial]}- so if the air in the room l)ecomes more or less saturated with carbonic acid and the vapors of water, the result being' the formation of poisonous carbonic oxide. The calorific value of natural gas varies slightly in different localities, as the amounts of carbon and hydro- gen vary. Those natural gases which contain the high- est percentage of carbon gi\'e the best results in evap- orating water. The standard used in measuring the evaporation of water is called the liritish Thermal Unit, written B. T. U., and is the amount of heat necessary to raise 1 pound of pure water 1*^ F. at or near 39"-', whicii is the temperature of the maximum density of water. The quantity of air necessary for the perfect combustion of natural gas varies from 10.4 to 10.8 parts of air to 1 part of natural gas. The products of combustion are water and carbonic acid. The ultimate heat units in any fuel are not all avail- able for the conversion of water into steam, a propor- tion being lost l)y radiation and in causing sufficient draft to supply the fresh air that is required to keep up the combustion. A number of tests have fullj- demon- strated that when ordinary care is taken in burning- natural gas under boilers in actual service, 1 cubic foot of natural gas will do the work equi\'alent to the evapo- ration of 1 pound of water at and above 212"^ F. Since 20 cubic feet of ordinary- natural gas weigh 1 pound, 1 pound of natural gas will evaporate 2() pounds of water, while, under similar conditions, 1 pound of petroleum will evaporate onl}- 16 pounds of water, and 1 pound of good coal will evaporate but 10 pounds of water; there- fore 10 cubic feet of gas is equal to 1 pound of coal, or 20,000 cubic feet will equal 1 ton of coal. Only two articles have been made directly from nat- ural gas; they are lampblack and gas coke. Lampblack is still made, but gas coke ceased to become a j^roduct when natural gas as a fuel was consumed in an economical manner. In isolated districts, where it is difficult to convev the natural gas to market, numerous wells have been made profitable by the conversion of the gas into lampblack. The process is extremely svasteful, as the amount of carbon actually secured is probably not more than one-twentieth of the carbon contained in the gas consumed. In the manufacture of lampblack or carbon black a great number of small jets are made to impinge upon a pipe, through which there is a circulation of water to keep it cold. The carbon is deposited on the pipes in very thin films and accumulates very slowh-. Automatic scrapers and brushes are arranged to collect the deposit, so that the flames can have the clean, cold surface of the pipes upon which to deposit a fresh sup- ply. The lampblack thus secured is said to be the verj^ finest, and is used extensively at home and abroad. Gas coke is a product of the impei'fect combustion of natural gas when the unconsumed portion is highly heated. Under such condition the gas is decomposed and pure carbon is deposited. Generalh' the deposit was obtained from the fire boxes of the heating fur- naces used in the maiuifacture of wrought iron, and found a i-eady sale for use in the manufacture of elec- tric'light carbons. It is similar in appearance to the coke formed from coal, and has a metallic ring when struck with a hammer. 77ii' vh'am'n/iiient of the ouPput of gas 'welh. — To as- certain the outflow of a gas well in cubic feet per hour it is necessary to determine the momentum, either by the application of the Pitot tube or, if the pressure is greater than 5 pounds, by the use of an accurate steam gauge. In using the Pitot tube one end of a shoot pipe is placed at right angles to the flow from the well and as nearly even with the orifice of the pipe as possible — one-third of the diameter from the outer edge. Lead- ing away from this small nipple there is an elbow and a piece of pipe attached to a siphon gauge, in which the gas presses against the water or mercury. There is also a scale attached to the gauge showing the inches and tenths of an inch of the height of the column caused by the momentum. This method of application and the fornmla for determining the flow were first applied by Prof. S. AV. Kobinson, of the Ohio State University. Compressors. — The pressure in most of the original fields at first was ample to convey large quantities of gas a number of miles through medium sized pipes. In after years a gradual reduction in the pressure made it necessarj' to install powerful compressing machiner3\ At first gas was used in the generation of steam as a motive power; afterwards the most successful and economical compressors were those in which gas was exploded directly in the cylinder. Many of these compressor plants installed by the natural gas companies are models of the highest me- chanical efficiency, some of the individual compressors developing as much as 2,ii00 hoi'sepower and weighing from 2.50 to 500 tons. The more recent ones are so constructed as to use natural gas engines instead of steam engines for motive power. By the operation of compressors with the gas engine there is a saving of from Id to 5i* per cent in the amount of gas used, as I compared with that consumed under boilers supplying double expansion engines. One of the first gas com- pressor plants using natural gas as a motive power is in use at Halsey, McKean county. Pa. This plant consists of four horizontal gas cylinders, in which nat- ural gas is exploded, each having a diameter of 25 inches and a stroke of 1 feet. These cylinders are set tandem, two on each side of the main shaft, which car- ries two 13-foot fly wheels and operates four compressor cylinders. Two of these cylinders are high-stage com- pressors and two are low-stage compressors, the former being 15 inches in diameter and the latter 31 inches in diameter; the stroke is 2 feet. The main dimensions are: Length, 75 feet, and breadth at flv wheel, 18 feet. In this engine one horsepower per hour is produced bv the consumption of 9 cubic feet of natural gas. Tlif ndtiiral gas engine. — Since the first successful 776 MINES AND QUARRIES. use of the natural gas engine about ten years ago, its application has been rapid as well as eminently snccess- ful; wherever natural gas could be secured this engine has been installed, and has fully demonstrated its econ- omy and reliability. One of its greatest triumphs is that it dispenses with the costly and extravagant boiler. Its merits are fully demonstrated in its application to the pumping of petroleum wells and the operation of the smaller force pumps used in the transportation of the petroleum. Its general introduction into the petroleum producing fields has enabled the operator to pump economically small wells that otherwise could not be operated, and it has also enabled him to handle large quantities of water where petroleum must be secured at a small outlay. Petroleum wells are often pumped in clusters of from 5 to '25, the number varying accord- ing to the depth and other conditions. AVhere the wells are comparatively shallow, and not too far apart, they can be pumped readily and with small loss b^' means of rods operated by steam or gas engines. For- merly deep wells were operated by a single boiler in or near the center of a cluster of from •4 to wells, each of which had a steam engine connected with steam pipes radiating from this boiler. The loss by condensation when this method was used was very great. The gas engine has in many instances replaced the steam engine, the change often being effected by the removal of the steam c^dinder and the substitution of a gas cylinder. The boiler is dispensed with. The gas engine will run unattended for hours, as it is only necessary that it be kept lubricated. The steam engines usualh' employed in petroleum operations are generally not well cared for, so that the steam used for tlie work accomplished is often extravagant. In ordinai-y prac- tice the internal combustion engine, of which the natural-gas engine is a type, is most economical, and equals in effectiveness the triple expansion condensing engine. Wheii the natural gas engine is operated in the most economical manner, there is a saving of nearly 50 per cent in fuel over that required to bo consumed under boilers to operate high dutj^ steam engines, and a saving of about W) per cent over the consumption required for the ordinary steam engine. DiHti'llmtion of natxiral gas to tlie coiiHuincr. — Almost the entire production of natural gas is distributed to the consumers by wrought iron pipes, which vary from 1 inch to 20 inches in diameter. Thei'c are also in use a number of miles of ri\'eted wrought iron pipes of a diameter of 3 feet. Lately many long lines ha\e been constructed of pipe IS and MO inches in diameter. The pressure at the field end of these lines is in some instances as high as 400 poimds to the square inch, but it is usually from ino to 2(Hi pounds. Where the rfatural w(dl pressure is not sufficient, it is incr(>ascd by large compressors, before described. Wrought iron pipes G inches and less in diameter are usually' connected by collai's with thrtsaded joints. Recently the joints for the larger diameters have been made of sleeves of a larger diameter, between which and the pipe rubber packing is forced by flanges drawn together by bolts. This variety of joint is satisfactory in every way, and has a number of advantages over the screw couplings for larger diameters. It overcomes the trouble due to the expansion and contraction of the pipe line without a resort to fine bends: it enables the pipe to swing more or less; it adjusts itself to the inequalities of the surface; it cheapens the first cost, because no threads have to be cut; it is not so easily injured in transporta- tion, and it is etticient in preventing disintegration by electrolysis in localities where electric roads are oper- ated. Usually the main line pressure is reduced near the city or town line to a pressure of from 20 to 50 pounds, and the gas is fed into an intermediate .sys- tem of pipes supplying the regulators that deliver the natural gas into the mains from which the consumers are supplied. In the cities and towns there are two methods of dis- tribution. The more common system is called the low pressure system, and usually carries a pressure of from 3i to 7 ounces to the square inch. This system consists of a series of pipes from 2 to 12 inches in diameter laid in the street at a depth of from 2^ to 3 feet, the largest sizes Ijeing placed in the localities of the greatest con- sumption. To these pipes are connected the service pipes, which are usually from 1 to \\ inches in diame- ter, and lead into the consumers" houses. Between the high pressure lines and the low, automatic regulators are placed, adjusted by weights and diaphragms, in such a manner that the pressm'c remains almost constant, even when more or less natural gas is conveyed from the high to the low pressure. A series of liquid seals are used in <'onnection with most of the regulators, which prevent any pressure over 16 ounces on the low side from get- ting into th(^ dwellings; the liquid seals will blow out when such pressure is reached. Another system is that of placing a reducing valve inside or near each house, this valve being connected with a smaller pipe conveying a higher pressure which is reduced liy an individual regulator to a pressure of from -1 to t! ounces. The points of consumption are in many instances from 100 to 250 miles distant from the ])lace of production. The total length of pipes of all sizes from 2 inches up to 3G inches in diameter in use in the United States for conveying natural gas at the close of 1902 was 131,85!>,(:)3r, feet. This is equal to 2-l-,973.41 miles- enough to more than girdle the earth at the equator. Natural gas is usually sold to the consumer b}^ the cubic foot, at a standard pressure of 4 ounces to the S(iuare inch, or 36 pomids to the scjuare foot, at a tem- perature of 60^ F. In many instances it is convenient to dispose of the gas to consumers at higher pressures, and then it is necessary to construct meters of propor- tional strength. The mean pressui'e of the atmosphere for the elevation at which most of the natural gas is sold is assumed to be 14.4 pounds to the square inch. 778 MINES AND QUARRIES.

By GEOK(iK P. Mkkhili,, Ph. D. As earl}' as the Seventh Census, statisticiS of the produc- tion of stone for building- and decoration were shown. Under the name of ''stone and niarlile quarries" a total of i,l-l:-i quarries, with an output \'alued at $8, ISO, 11,5, was reported. This, however, did not include the value of stone burned into lime, which was separately reported and amounted to $S, 386, 2-1:2. There were also 5 slate quarries, with a product valued at $iiitt,().^(;. Statistics for slate and marble quarries have Iteen sliown at each subsequent census, but the first systematic and fairly - satisfactory report of the stone industry, as a whole, was begun under the direction of Dr. George W. Hawes at the time of the 'I'enth Census in 1880. The unfortu- nate death of Doctor Hawes, in the midst of his labors, prevented the carrying- oat of his plans as completely as might have been desired, ))ut enough was aceonq)lished to establish a basis for future work and furnish material for comparison. It will be noted that since 1880 the increase in num- ber of cfuarries was -i.^H'.i, and in value of products, $52,086,383. The industry has, therefore, practically quadrufDled during- the twenty -two years. No compar- ison can be made l)etween the wages for 18S0 and those for 1',I02, as wages were not reported in 1880; the increase in salaries and wages from 1889 to 1902, however, was $11, -14:8. 369, or 37.5 per cent.

Although not clearJ_y shown by the statistics, it i.s nevertheless true that there exists in the stone industry the same tendency toward the concentration of capital and the formation of stock companies as in other branches of trade, though possilih' not to the .same extent. This is due not altogether to tlio desire for com))ination with a view to controlling trade, but in part at least to a change which has taken place in the character of the industry'. The introduction of machinery, often of an expensive type, for both quarrjdng and dressing, ren- ders neces.saiy a larger initial outlay than in the earlier days of the industiy when hand labor alone Avas em- ployed. The fact, too, that the quarrier in many ca.ses now contracts not merely to furnish the stone, but to furnish it cut and ready for its definite position in the structure, even if he does not contract to set it in place as well, involves a larger capitalization and supply of available funds. Of the operators shown in the foregoing table 5.7 per cent reported a product valued at $50,(t00 or more, the value of their combined product constituting 57 per cent of the tohd ; 91. 3 per cent reported a product valued at less than $50,000, their combined value of product constituting 43 per cent of the total.

The variation in the numbers employed during the summer and winter months is readily explained when it is re- membered that ([uarrying is an outdoor pursuit and the severity of the northern winters practically puts a stop to all building and outdoor work. The compara- tively recent developments in the Southern states, where the climatic conditions are less severe, have ren- dered this discrepancy much less marked than in times past.

The 71,156 wage-earners shown ahove as employed in stone quarries constituted ahiiost one-eightli (liJ.2 per cent) of the total number reported in 1902 l)_y all the mines and quarries of the United States. The rates of pay were somewhat lower for stone quarries than for all minerals combined, the range of wages for the bulk (70.9 per cent) of tho.se employed in stone i[iiarries having been from $1 to §2,24, while of the total for all minerals 80. S per cent received between $1 and $2.74 per day. The ditference in wages is more clearly shown, perhaps, in the following comparison: AA^heiT the fig- ures for all minerals are combined it is found that 57.2 per cent of the total number were paid 113 per day or over, while 42.8 per cent were paid less than $2. In stone quarries, on the other hand, only 30.4 per cent of the wage-earners received $2 per daj' or over, (19.(1 per cent of them having been paid less than $2. Of the 71,156 wage-earners 49,945 (about seven- tenths) were returned as quariymen and stonecutters. The greatest concentration of these wage-earners was between rates $1 and $2.24, 79.3 i^er cent of the total number being included. The next four groups, includ- ing those who received from §2.25 to §3.24 per day, cofistituted 15.7 per cent of the total number. Thus it is seen that 95 per cent of the (juarrj^men and stone- cutters were paid between $1 and $3.24 per day. The total number of engineers employed in stone quarries in 1902 was 2,540, the range of wages for 80.1 per cent of them being from §1.50 to $2.74 per day. There were 933 firemen reported, 83 per cent of whom received between $1.25 and $2.24 per day. About one- third of all the engineers are included in the single rate group, $2 to $2.24, while 35.5 per cent of the firemen are'included in the group, $1.75 to $1.99. There is less concentration in the figures for machinists and other mechanics, the range of wages for 2,780 of them — 93.4 of work done, for whom average daily earnings are shown. per cent of the total number — being from $1.25 to $3.24 per day. The number of boys under 16 years employed in stone quarries was 731, only 1 per cent of the total number of wage-earners. Of these boys, 69 were paid less than 50 cents a day and 647 were paid lietween 50 cents and §1.24. Under the head of "all other wage-earners"' are included 14,031 employees, more than three-fourths of whom received from fl to $1.74 per day and 16.7 per cent received from §1.75 to §2.24. Siq)p] ii'K, iiuiti'-fidlK^ and iiiinvvlhuieous expenseft. — As .shown in Table 37, the total amount expended for sup- plies and materials was $10,739,736. Of this amount, $5,403,912, or 60.3 per cent, was ex.pended in quarrj'- ing limestones and dolomites; $2,493,065, or 23.2 per cent, in quarrying siliceous crystalline rocks; $1,298,190, or 12.1 per cent, in quarrying sandstones and quartz- ites; $825,822, or 7.7 per cent, at marble quarries; $680,361, or 6.3 per cent, at slate quarries; and $38,386, or four-tenths of 1 per cent, in connection with the production of silica sand. Miscellaneous expenses amounted to §3,976,865, of which total $1,156,754, or 29.1 per cent, was paid for royalties and rent of quarrying plants, and $2,S20,111, or 70.9 per cent, for rent of otKces, taxes, and other sundries. Mechanival jxnrer. — The total primary power re- ported aggregated 178,878 horsepower, of which 167,744, or 93.8 per cent, was applied through 4,265 steam engines, and 1,378, or seven-tenths of 1 per cent, through 92 gas or gasoline engines. Fifty-six water wheels furnished 6,731 horsepower, or 3.8 per cent; under "other power," 2,114 horsepower, or 1.2 per cent, was reported; and 911 horsepower, or five-tenths of 1 per cent, was rented from other establishments. 788 MINES AND QUARRIES. There were, in addition, lit electric motors owned by tlie operators reporting- them, having- a total horsepower of 3,521. Of these, 35 with a horsepower of 769 were used in the production of limestones and dolomites; 32 with 2,220 horsepower, in the production of marble; and 23 with -142 horsepower, in the production of sili- ceous cr3^stalline rocks. Production. — The value of the annual production of all classes of stone from 1890 to 1902 is shown in the following- table: Table 6. — Value of amnial production of atone: lS90to 1903.^ [United States (.ieolcigieal Survey, " Mineral Resources of tlie United States."] YEAR.

The values increased and decreased alternately from 1891 to the close of 1895, and there was a further decrease in 1896. when the lowest value was reported. Since 1896 there has been a steady increase. These fluctuations of value were distributed through all classes of stone. Discussing the period covered bv this table, a decline in the production of granite, limestone, and sandstone began in 1891. Th(> production of .slate declined in 1893, but increased a little in 1894. The production of marbh? fell off in 1893. The return io more prosperous conditions began in 1897, and liy 1902 the earlier (jutput had been equaled or exceeded for all classes of stone but sandstones and i|uartzites, the \'alue of which for 1902 was still below its \-alue for l8'.»0. Table 37 presents detailed statistics of all classes of stone for 1902. CLASSIFICATION A\D OCCUKIIENCE. The matter of the classification of such rocks as are here considered has from the very beginning- been one of difficulty, and one which has not yet been solved in a thoroughlv satisfactory manner. As a compromise between the minute subdivisions desired by the scien- tists and the extremely general and often erroneous classification of the quarrymen, the following division has been adopted, which is essentially that followed in 1880: 1. Limestones and dolomites. — These are all sedi- mentar}' and bedded rock.s, composed essentially of lime carbonate, or the mixed carbonates of lime and magnesia. Such have been found to pass into each other by insensible gradations, certain quarries in the states of the Mississippi valley producing at the same time material which, if classed on purely chemical grounds, would be relegated to both divisions. Obvi- ously a too close adherence to scientific principles would lead to confusion, and hence all are here grouped together. '2. Miidile. — Here are included stones identical in composition with those noted under limestones and dolomites, but which through changes, mainly physical, have come to possess properties rendering them desir- able for high-grade building or ornamental work. As with the last, they are variable in composition. The marbles of the Rutland, Vt., area, for instance, are largely limestone, while those of the Berkshire count}', Mass., area are largelj' dolomite. With the marbles are also included a small series of serpentinous rocks, which are likewise utilized for decorative purposes. 3. Sandstones andquartzitex. — The rocks here brought together are composed es.sentially of consolidated sands. They are made over, as it were, from the detritus of preexisting rocks. Those classed as "quartzites" are .sandstones which have Ijcen rendered more or less crvs- talline through the deposition of silica between the original sand particles, as is the case with the '"jasper" of Sioux Falls, S. Dak., or the Potsdam sand.stone of St. Lawrence county, N. Y. The tuffs and other vol- canic f ragmental rocks are also here included. .^. Silica sand. — This is crushed sandstone, used in the manufacture of glass and for other purposes. 5. Siliceoiix cfi/xtaUinc nicl'x. — Here are included the true granites and syenites, together with the trappean rocks, such as are often designated as black granites: the gneisses, or so-called stT'iped or bastard granites: the mica schists: and nielaphyi-e, ba.salt, andesite, and other A'olcanic rocks. 6. Slaf,'. — This is an argillaceous rock, which, through compression and shearing-, has been more or less meta- morphosed and rendered Kssile, by virtue of which pi'operty it may be split into slieets suitable for rooting and other purposes. Oiriirrcncc. — In this connectitm the following state- ment relative^ to the possible resources of the various states of the Union and their present development is not without interest. The list shows the rocks which are known to occur in each state in quantities sufficient for (juarrying. The names in small capitals indicate those which were actually' quarried during 1902.

A critical examination of the foregoing statement show.s tliat the siliceous crystalline rocks, marbles, and slates are limited in their distribution mainly to the areas east of the Appalachians, those bordering along the Great Lakes, and those west of the front range of the Rocky mountains. The .sandstones and limestones, on the other hand, are more widely distributed, although found best developed for quarry purposes in the great interior regions of the Mississijopi valley. These points will lie l)rought out in greater detail in the discussion of the various classes of atone. The importance of a study of the stone resources of the various states is being gradually recognized, and re- ports covering the subject with more or less complete- ness were issued by Ohio and Minnesota in 1S84, New York in 1888, Arkansas in 1890, Indiana and Pennsyl- vania in 189(i, Maryland and Wisconsin in 18!J8, and Georgia in I'.toa. LIMESTONES AND DOLOMITES. The rocks brought togetht'r here differ from those included under the head of marjjle not so much in composition as in physical properties. They I'eprescnt the limestones and dolomites of the ordinary unmeta- morpho.sed type, such as are lacking in qualities ren- dering them susceptible for ii high grade of orna- mental work, but suital)le, it may be, for building. As will be noted, a large proportion of the material quar- ried under this name was utilized for other than struc- tural purposes.

Statistics for 1880 are not suitable for comparison, since the census returns for that year excluded all material not used for building purposes and did not dill'erentiate between limestones and marbles. (See Table I'l.) The number of quarries has increased b}- 1,292, or 66.1 per cent, since 1889, the amount paid in salaries and wages has increased $6, 472, 400, or 63.9 per cent, and the value of products 111,346,622, or 59.4 per cent. Of the 3,137 operators reported for 1902, 2,282 were indi- viduals, 480 firms, 344 incori^orated companies, and 31 cooperative associations and other forms of organiza- tion. In 1902 development work was reported at 3 quar- ries — 2 in California and 1 in Wisconsin. Four salaried officials, clerks, etc., received $2,800, and there were 33 wage-earners to whom !jln,43ii was paid in wages. Miscellaneous expenses were §1,075, and supplies and materials cost $5,250. Eittployi'cK and iriujcK. — In 1902 the 31,547 wage- earners formed 93.4 per cent of the total number of employees and the $14,75(1,638 paid them as wages -was 88.9 per cent of the total amount expended in salaries and wages. In addition, !l>3ti,3sl was paid for contract work, which gave employment to 137 persons.

Of the quarrymen and stonecutters, 20,430, or 92.7 per cent, are included between the same rates. There is little need for highly skilled workmen in limestone quarries, and consequently the rates paid are practicall}' the same as those paid in all trades for unskilled labor. The rates paid to engineers and to machinists and other mechanics were somewhat higher than those for other wage-earners; S3. 7 per cent of the engineers re- ceived from Si. 50 to $2.74 per day, and 7t).9 per cent of the machinists and other mechanics were included between the same rates. The range of wages for (i\-er three-fourths (78.5 per cent) of the tircnien reported was between $1.25 and $1.99 per day. In all, only 258 boj's undc.T lU years wei-e reported, which number is less than 1 per cent of the total num- ber of wage-earners. Of these boys, id wei'c paid less than 50 cents a day, and 239 were paid from 50 cents to $1.24. The boj's reported were not employed in any one locality. There were 51 in Indiana, 3<> in Virginia, and in F enns viv una. ^rho othci-s were distriliuterl in small groups tlirtrngh a large number of states. Under ''all other wagi'-eai'ners '' are included 7,<)20 men, 22.3 per cent of the total number. The rates paid to these emplovees ditier very little from those for quarrymen and stonecutters. About four-tif ths (5,628, or 8n.2 per cent) of those classed as "all other wage- earners" received between $1 and $1.74 per day, and 1,103, or 15.7 per cent, received from $1.75 to $2.24.

The total value of the output for 1902 was §30,411,801, of which o\\\y $.5, .563, 084 was utilized for building pur- poses, the remainder being used for flagging, curbing, lime burning, roadmaking, rubble, riprap, flux, etc. The largest single item, which amounted to $9,335,618, was for lime burning, and the second, thatof 15,271,262, was for flux in metallurgical operations. A large amount was also used for macadam, not so much on account of its suitability as because of its cheapness, the almost complete absence of siliceous, and especially trappean, rocks from the ]Mississippi valley states necessarilj" limiting the selection to either limestone or sandstone. The detailed statistics of this industry for 1902 are shown in Table 38. Ornirrence. — Rocks of this type, though occurring in every state of the Union, are found in their maxi- mum development in the states of the Mississippi val- ley, where the agents of metamorphism have exercised but little influence and the rocks have retained their original sedimentary character. In some instances rocks of this class are of a highly fossiliferous nature. Such, however, are not as a rule utilized for building purposes, but rather for lime burning, etc. Those utilized for architectural purposes are principally of the tine grained homogeneous type, such as the dolo- mitic limestones of Lemont, 111., or of the oolitic tj'pe, such as the stones so extensively de\'eloped in the re- gion of Bedford, Ind. These stones work readily under the tool, and when free from injurious constituents are admirably adapted for elaborate structures where much car\-edwork is required. This is especiallj' true of the stone at Bedford, where the conditions are particularly favorable for f|uarrying, the beds having retained very neaily their original horizontalit}'. The quarry devel- opment is extensive, as is evident from the illustration given in Plate I. The ease with which these stones are removed by the aid of machinery from the quarr}' bed, and the readiness with which they may be worked, as well as their satisfactory colors, have rendered them general favorites for building purposes and they have found their way into the larger cities all over the country. MARBLE. The stones here included under the head of marble are mainly those composed of carbonate of lime, or the mixed carbonates of lime and magnesia, in other words, limestones and dolomites, which,owing to their color and physical pro])erties, are suitable for high-grade building and ornamental purposes. It should be stated that no sharp line can be drawn between what is popularlj^ known as marble and the common limestones and dolomites, as what is or what is not suitable for decoration must depend largely upon the taste of the individual. The stones here included are, however, those which are sold as marble, and in two instances serpentinous rock — the so-called verd antique marble. The following table is a comparative summary of tlie marble industry from 1870 to 1902.

In the published statistics of the census of 1880 no discrimination was made between the two classes of rocks. The writer, knowing the character of the out- put of the various quarries, estimated the value pro- 792 MINES AND QUARRIES. ducedthat year at $2,0'±4,225 which, it will be ol).served by reference to Table 12, was increased to §3,4SiS,17u in 1889 and to $5,044,182 in 1902. There were 83 quarries in operation during' I'.IO:^ with 352 salaried officials, clerks, etc., and 1,070 wage- earners, while in 1889 there were 103 quarries with 254 salaried officials, clerks, etc., and 4,275 wage-earners. The decrease in the number of active (juarries is very probablj' due to the consolidation and incorporation of companies. The apparent decrease in the number of wage-earners may be accounted for by the different methods pursued bj- the several censuses in obtaining the average number employed; also by the introduction of machinery and improved methods in quarrying. That this decrease is only apparent, seems all the more probable when it is taken into consideration that both the amount paid as wages and the value of the marble produced increased to a marked degree during each census year. There were 10 quarries reported as being developed by as many operators, 8 of whom were incorporated companies and had issued capital stock and lionds to the amount of $5,031,500. Six of these quarries were located in Washington, and there was 1 each in Cali- fornia, Kentucky, Montana, and Utah. These gave employment to 7 salaried officials and 25 wage-earners, who received |22,405 in salaries and wages. From these 10 quarries supplies and materials to the amount of $5,218, and miscellaneous expenses to the amount of $2,550, was reported. There were 114 quarries reported idle during 1902 and these were controlled by 114 operators, 53 of whom were incorporated companies. Capital stock and bonds were issued to the amount of $9,127,250 by 25 of these companies. Cajiltal sfocl: of hiciii'piirateil voiiipfintrs. — Of the 75 operators of productive ((uarries, 45 were incorporated companies. Forty-three of these made returns showing a capital stock of $17,609,900 and a bonded indebted- ness of $2,708,500.

This has been the case since the very incep- tion of the industry, though the proportional difference in output is being continually lessened as developments are made in other .states. While the value of the prod- uct of Vermont has increased rather than diminished, the state in 1902 produced only 52.1 per cent of the output of the United States instead of 62.2 per cent, as in 1889. Other differences are equally marked. These are due mainly to the remarkable developments in Georgia, whereby the product was increased from $196,250 in 188'.t to $660,517 in 1902; to the reopening of the long abandoned quarries in Berkshire county, Mass.; to developments near Avondale, in Chester county. Pa., in Adams and Stevens counties. Wash., and minoj' developments in INIontana and Utah. Occurrence. — The matter of the geographic disti'i- })ution of marbles throughout the United States is of considerable economic importance. It will be noted by reference to Table 3',> that a very large proportion of them are to be found in states bordering along the Appalachian mountain system. Recent developments .show that materials (if the same iiatui'c exist in the states we.'^t of the front range of the Kocky mountains, hut thus far little more than development work has been done except in California and Washington. The entire region lying lictween the Ajjpalachians and the front range of the Rocky mountain.s to the westward is quite unsupplicd with anything that can properly be designated as luarlile, the geological conditions which were instrumental in priiducing the necessary altera- tion from the common limestone having here been inoperative. \\\\\\ rcfereuct" to the al)ove distriliution the follow ing statement as to color, texture, and uses may lit. adtled. beginning with the most northerly of the marble producing states: Vermont. — jNlarble.s of a holocrvstalline granulai structure, \ary ing from pure white to white veined with blue-gray and greenish to dark cloiRhnl lilue-gray, occur in a somewhat interrupted belt extending throughout the entire length of the western part of the state. The STONE. 795 quany industry is developed to the greatest extent in Rutland county. Views showing the pre^ient condition of quarries at West Rutland and Proctor are given in Plates II, III, and IV. The stone is used for building, monumental, and decorative work. Chocolate, red, and variegated forms, used for tiling and interior deco- ration, are found in the vicinity of Mallet bay. Massachusettt<. — Holocrystalline rather coarsely gran- ular building marbles of a white color are found in the various towns of Berkshire county. i\v«' Yorli. — Coarsely crystalline white and grayish dolomitic marbles, which are used mainly for building purposes, occur in Westchester and St. Lawrence counties. Pennsylvania. — Holocrystalline granular marbles of a white and gray color, used mainl}' for building pur- poses, come from Montgomery and Chester counties. Maryland. — Holocrystalline granular white marbles, used for general building purposes, arc quarried in Baltimore county. Georgia. — Holocrystalline coarsel,y granular white clouded and pink marbles, usedmaiidy for building but also for interior decoration and monumental work, occur in Cherokee and Pickens counties. (See Plate V.) Tennessee. — Pink, gra^^ and chocolate and white mottled stone, used almost wholly for interior decora- tion, is found in the region about Knoxville and Rogers- ville, in eastern Tennessee. Was/ungto?). — A pecidiar green or green-white mot- tled stone, consisting of an admixture of lime and mag- nesian carbonates, brucite, and serpentine, is being developed near Spokane, and worked into various art objects, such as vases, urns, and bowls, an entirely new departure in marble work. A verj' large proportion of the marbles used for in- terior decoration, and, indeed, almost the entire supply of the verd antiques, are still imported, Italj-, Africa, and Greece furnishing the largest amounts, although of late a considerable quantity has been brought from Nor- way. This importation is due in part to the more desirable quality of the material, and in part to the cheapness of foreign labor and low ocean freight rates. A detailed summary showing the statistics of the marble industry for 1902 is given in Table 39. SANDSTONES AND QUAKTZITES. Under the head of sandstones and quartzitos, is in- cluded a widely variable series of rocks, composed, as the name suggests, largely of siliceous sand, which, through the influence of cementing materials or natural compression, has become sufEciently indurated to be utilized for building purposes. With them are also included certain rocks of similar origin but which, through the deposition of a siliceous cement, have be- come partially recrystallized and are known as quartz- ites. The so-called "Potsdam sandstone" of New York and the "jasper" of Sioux Falls, S. Dak., are good examples of this latter type. Here, too, are included the "bluestones" of New York and Pennsylvania, so widely used for flagging purposes, and the volcanic tuffs. The following table presents comparative statistics for this industry for 1902, 1889, and 1880.

There has been an actual increase in the number of quarries in oj^eration, but this is due to the opening of small rural quarries, and is not accompanied by an increase in any of the expenditures except those classed as miscellaneous. EnipJinjeex and vxtgcs. — The total number of salaried officials and wage-earners was 11,295, the wage-earners contributing 10,448, or 92.5 per cent of this number.

A veiy few, only ^.S per cent, were paid less than $1.25, and the balance, 2,409, or 23.1 per cent, were distributed in -iiiiall groups between $2.25 and §4.25. It will be noticed that there was a greater concentration of the several classes of wage-earners at a few I'ate groups in sand.-itone and quartzite quarries than in other stone quarries. More than two-thirds of all the wage-earners were classed as quarrymen and stonecutters, 7,117 men htiv- ing been reported under that head.

OrriirriiK-c. — The sandstones iire among the nio.st variable and widely distributed of American building material. Those which have been most sought on ac- count of their color and working qualities are the red- brown Triassic sttjnes of the eastern United States, the light-gray to butf Carlioniferous stones of the Missis- sippi vtilley, of which the so-called "Berea grit" is a familiar type, and the New York and Pennsylvania l)lue.stones, utilized mainly for flagging purposes. The sandstones are for the most part comparatively ea.sy to work and. next to the granites, have been more generally employed for structural purposes than any other of our natural Iniilding materials. Thev are found interstratitied with rocks of all geological hori- zons from the Caml)rian down to the Tertiary and occupving all positions with relation to horizontality. In the mountainous regi(ms the deposits tire naturally more or less distorted and occupy more or less inclined positions. In the region (.if the ^Mississippi valley, where the geological agencies have been much less violent, the beds retain their original horizontal posi- tion and afl'ord admira))le fticilities for ([uarry opera- tions upon a large scale. It is upon these beds that some of the largest cjuarries in the country have been opened. Figures 1 and 2, Plate VI, show the position of tlie stone and the remarkable natural facilities for extraction as well as the great amount of development which has taken place at Amherst and Berea, Ohio. 798 MINES AND QUARRIES. SILICA SAND. Silica or siliceous sand includes not only sand suit- able for the manufacture of glass, luit also a large quantity designated as engine and furnace sand and sand for other uses, it being impossible to separate the statistics. Of the value of product, i^50,8l:L is for sand produced at regular sandstone quarries, being the waste or scrap stone crushed. In such instances the statistics of salaries, wages, and other expenditures, not being separable, have been included with those for sandstones and quartzites. At the census of 18^0, glass sand was separately reported. Thirty-three mines were shown, at which 332 employees received wages amounting to 196,598, and the value of the product was $239,095. At the Eleventh Census, " sand for glass " was included with sandstone. The following table is a summary for 1902: Table 35. — Suininnrii: 100.'.

Of the 2G quarries, 10 were in Ohio, 14 in P(.Mnisyl- vania, and 2 in West Virginia, the statistics of the last named being included with those of Peiin.sylvaiiia to avoid disclosing the business of individual operators. These quarries were controlled by 2n operators, 5 of whom were individuals, 5 firms, and In incorporated companies: 7 of these companies were reported from Penns\'lvania. Emjfloyees and wages. — The 335 wage-earners consti- tuted 90.0 per cent of the .salaried employees and wage- earners, and the $149,114 paid as wages was 84.6 per cent of the total salaries and wages. The average number of wage-earners empjoyed each month is shown in the detailed summary. Table 41. The greatest num- ber, 380, was reported for Septeml)er, and the least, 264, for Februarv- This table shows also the avi.'rage number of wage-earners at specified daily rates of paj- hj occupations. Of the 335 wage-earners, 2(il. oi- 77.9 per cent, were reported as receiving from SI. 25 U) $1.74 per day. There were 149, or 44.5 per cent, employed as quarrymen at rates ranging from 75 cents to $2.24 per day. The crushing of the stone entailed the em- ployment of a large number of laliorers and other work- men, who wei'e reported as "all other wage-eai'ners" and numbered 154, or 46 per cent, of tlie total. Silica sand is the only subdivision of the stone industi-y in which no boys under 16 years of age were repoi'terl. Supplies, materials, andiaiscellaneous expenses. — Sup- plies and materials costing $38,386 were reported, $13,598, or 35.4 per cent of the total, having been expended in Ohio. The miscellaneous expenses amounted to $18,776, of which $8,373, or 44.6 per cent, was for royalties and rent of quarrying plants, and $10,403, or 55.4 per cent, for rent of offices, insurance, and other sundries. Of the total, $11,210, or 59.7 per cent, was reported from Pennsylvania and West Vir- ginia, and $7,566, or 40.3 per cent, from Ohio. Mechanical pcnoer. — The total power owned was I'e- ported as 2,000 horsepower, of which 805 was reported from Ohio and 1,195 from Penn.sylvania. Of this total, 1,980 horsepower was supplied by 33 steam engines, 16 of which were in Ohio. I'mdiictiiin. — The United States Geological Surveys has not pul)lished annual statistics of glass sand except for 1885 and 1902, and these statistics are not compara- ble with those of the census, because they include sand from pits and banks as well as that crushed at sandstone quarries. i Chief among the sand producing states, in 1902, was- Pennsylvania, where sand was found in all forms. This state was followed closely by Ohio, where deposits were generally those of sandstone requiring crushing and screening. A small (juantity was reported from West \'irgiiiia. I The l(i qutirries shown for Pennsylvania (including the 2 in West Virginia) produced 312. 9S2 tons, or 70.2 per cent of the total production, the value being $269,015, or 0.S.9 per cent of the total value. Of this amount, 127,520 tons, valued at $l05,3t;7, was glass .sand; 31,500 tons, valued atS24,000, building sand; 15,241 tons, val- \ied at $18,8'.h;. furnace sand; and 138,721 tons, having a value of $120,752, was consumed for other purposes. The 10 quarries in Ohio produced 132,921 tons, or 28.1 per cent of the total quantity; the value was $152,274, or 36.1 per cent of the total value. Of this quantity, 6(1,396 tons, valued at $59,348, was furnace .sand; 2o,o3tl tons, valued at $24,896, glass sand; 3,750 tons, valued at $3,000, engine sand; and 48,739 tons, viilued at $(i5,o3o. was used for other purposes. Occurrence. — Silica or siliceous sand is known to exist in several states as a sandstone, requiring crush- ing and screening; as a stone that readily disintegrates when exposed to the action of the elements, and needs only washing or burning to reduce the amount of organic matter and other impurities; or as beds of pure sand, requiring no treatment to prepare it for use. Sand used in the manufacture of glass consists mainly of silica with alumina, and it may be iron, soda, lime, and potash in small and varying ciuantities. The value of the sand depends on its freedom from such impuri- ties as tend to produce a discoloration of the glass. A summary presenting detailed statistics of the silica sand industrv, by states, for 1902. is given in Ta))le 41. PLATE VII. —GRANITE QUARRY AT CROTCH ISLAND, MAINE (TWO VIEWSl. STONE 799 SILHEOUS CRYSTALLINE ROOKS. Under this clas.-ific;ition is grouped a somewhat vari- able series of rocks, iiK-luding not merely the true gran- ites, but also the gneisses (the so-called striped, stratified, or bastard granites of the (inarrymen), the syenites, the black granites or traps (diabases and gabl)ros), diorites, basalts, and andesites, and, in a few instances, the mica schists. The varying mineral character and structui'al features of these rocks are noted below: (iran'de. — A crystalline, granular, massive rock, con- sisting essentially of quartz, orthoclase, and mica or hornblende, with other minerals, as apatite and mag- netite occurring in microscopic quantities. Gneiiis. — A rock diti'ering from granite in that the various constituents are arranged in more or less par- allel layers, giving the rock a banded or foliated ap- pearance. It is often called stratified or bastard granite by the quarrymen. Syenite. — A rock, limited in quantity, differing from granite only in the absence of quartz as an essential constituent, i. e., one consisting of orthoclase with one or more of the minerals of the mica, amphibole, or pyroxene group. Elaeolite (nepheline) sijm'de. — A rock diti'ering from syenite in that the mineral elaeolite (nepheline) wholly or in part replaces the feldsj^ar. The " granite" near Hot Springs, Ark., is a good example of this I'ock. Dialiase and galihro. — Rocks consisting essentially of augite or hypersthene and plagioclase feldspars with accessory apatite, magnetite, and frequently black mica. These are hard and massi\'e rocks, often very dark gray to almost Idack in color, and in the case of the gafibro at Pleasant river, Me., known as black granite. In the majority of cases they are used only for road material. Dlorite. — A rock consisting essentially of hornblende or mica and plagioclase feldspar with other minerals in smaller proportions. In America this rock is little used for building material. Basalt. — A lava composed essentially of augite and plagioclase feldspar. It occurs mainly in the Western states. Ande!iji;-'s and iragi'x. — The total number of salaried officials, clerks, etc., and wage-earners was 20,213, and they received §12,300,881 in salaries and wages.

About three-fourths (76.8 jier cent) of all the wage- earners reported were classified as qiiarrymen and stonecutters. Their rates conform very closely to those for all occupations combined, 92 per cent of the total number having received between >51 and >^o.24 per day, as compared with 91.6 per cent for all occupations combined. An e.xamination of the figures for (juarry- men and stonecutters shows a marked concenti-iition at the rates from ^1.25 to 12.24 per day, then a slight falling off, and again a concentration for the rates from $2.75 to ?3.24 per day. This indicates the diticrence between the rates paid to cjuarrymen and thos(> paid to stonecutters, who tire niore skilled than the quiirrvmen. There were ()58 engineers reported, of whom 5(i3, or 76.4 per cent, received Ijctween $1.75 and $2.74 per day. The range of wages fen- 65. ,s per cent of the firemen was from $1.25 to $2.24 per day, 9.S per cent having received less than $1. 24.4 per cent, $2.25 or over. Kates were consideriibly higher for machinists and other int'chtmics, three-fourths of them having been paid from $2.(»o to $3.24 per day. The number of )»oys under Iti years reported was 206, of wdioiii 91 were in the New England states and 46 werti in South Carolina tind Georgia. The rates of pay for 164 of thes(> boys were between 50 cents and $1.24 p(>r day; of the others, 36 received less than 50 cents and 6 received $1.25 or o\'er. The group of "all other wage-earners'' includes 2,240 men, or 11. !» per cent of the total number of wage-earners reported. The range of wages for 2,o29 of them was from 75 cents to $2.24 per day. The number recei\ing $1.50 per day was probably greater than thtit at ;uiy other rate, since the wtige group, $1.50 to $1.74, includes ti much larger number than is in- cluded in anv other group.

Of the total yalue of product, §18,257,941, in 1902, a yalue of fT, 031,882 was used for building purposes and $3,998,911 for monumental work. The remaining material to the yalue of $7,221,201 was utilized for a yariety of purposes, but especially for paying blocks and as crushed stone for macadam. The introduction of machinery has rendered possible the utilization of the granites and other hard rocks in monumental work to an extent that was quite impossible when the stone was dressed by hand. The use of stone for macadam is largely a deyelopment of the past twenty 3'ears, and the demand for it for this purpose has caused the great increase in the number of quarries of trappean rock. This demand for crushed stone likewise enables the quar- ries worked mainly for building or monumental stone to dis])ose of their waste. The material used for macadam depends, howeyer, to a considerable extent on the kind of rock that is available in neighboring sources. While the trappean rocks haye proyed most desirable for this purpose, the total absence of material of this type from the great interior Mississippi yalley has caused the sub- stitution largely of limestone and, in some cases, of sandstone.

California, howeyer, dropped from the third to the fifth place in the list, while Vermont ad- vanced from the ninth to the third, and New Hampshire from the seyenth to the fourth. The changes in rank are due in some cases to a decrease in production, as in the case of California, and in others to an increase, as in the case of Vermont and New Hampshire. Geor- gia, which made such a remarkable increase between :;022:;-04- -51 802 MINES AND QUARRIES. the Tenth and Eleventh censuses, causing it to advance from twelfth to sixth in rank, has dropped to eighth, although there has been an actual increase in the product. The detailed statistics of the industry for lit02 are given in Table 42. During the earl}- history of the industry, when rail- roads were few, transportation of material as heavy as stone was largeh' by water. Hence it naturally fol- lowed that quarries situated close to the water's edge, like those of Vinalhaven and Crotch Island, Me. (see Plate VII), had a great advantage, and for a long time practically controlled the market. With the multiplic- ity of railroads, however, and the growing demand of inland cities remote from waterways, inland quai-ries at first wholly inaccessible, have become important fac- tors, and as a consequence the coast states have, to a considerable extent, lost prestige. Of the quarries developed during the last decade, on account of the quality as well as quantity of material thev furnish, those in. the vicinity of Barre, Vt., and Montello, Wis., are of greatest interest. The quarry near Montello furnishes a beautiful, compact, dark red-brown granite admirably adapted for monumental work. SLATE. The materials brought together in this report under the head of slate are argillaceous rocks, which, through the process of shearing and incidental chemical activitj-, have undergone a partial metamorphism, resulting in the development of a pronounced tendencj^ to split along certain planes, which nvay or may not be parallel with the original bedding, into thin sheets suitable for roofing purposes. It is necessarily a consequence that such are restricted to the regions of pronounced earth movements, such as have resulted in the formation of mountain ranges. The decrease in the number of quarries since 1889 has not been attended by a decrease in an^^ of the other items and is largely due to consolidation of interests. The apparent decrease in the numl^er of wage-earners is due to the methods employed by the various censuses in finding the average and in part to tlie introduction of machinerv. The steady increase in the amount paid as wages indicates that the difierence shown in the "average number" is not due to an actual decrease in the number of wage-earners. The production increased $2,213,538, or 63.6 per cent, from 1889 to 1902. Census statistics for slate quarries were shown as early as 1850, when the value of product was reported as $29,056, the number of quarries being 5. At the census of 1860, there were 22 quarries, with a pro- duction valued at $287,150. The census of 18T<.) was the first at which the mining industries were separately shown.

Thei-e was an increase in bS94, but a slight deci'ease in 1895. A gradual increase followed from that time until 1902, when the value of all slate produced was $5,696,051. Of this output material to the value of $4,950,428 was utilized for roofing, and the remainder, to the value of $745,623, for minor purposes. It is worthy of note that in 1S9<.» the value of the slate utilized for roofing purposes was $2,797,901, and that for all other pur- poses, $684,609. This indicates that no important new uses for slate have been found and that developments ha\'e been largely in the line of roofing materials. Ranked liy value of product first place was held by Pennsylvania, second by Vermont, and third by Maine, followed by Virginia, New York, and Maryland in the order named. Taljle 43, at the end of this report, presents detailed statistics of the industry for 1902. Occurrence. — Nearly the entire commercial supph' of roofing slates comes from states bordering upon the Appalachian mountain system. The prevailing color of the material is of a blue-gray to nearly black tint, though certain of the A^ermont quarries produce a green and purplish slate. The supply of red slate is at pres- ent limited whoUv to a few quarries in eastern New York. Except in California, there have been during the past ten years no developments of great significance, long established quarries in the states mentioned still furnishing the major part of the material. The quar- ries in Maine are situated wholly in Piscataquis county', those in Vermont along the western part of the state, bordering on the New Y'ork line, the developments of pailicular note being in the towns of Castleton, Fair Haven, Pawdet, Poultney, and Wells. In New York they are found in the closelv adjacent towns of Gran- ville and Middle Granville and other towns in Wash- ington county. The slates of New Jersev occur in Sussex and AA'arren counties; in Pennsylvania, partic- ulaily in Lehigh, Northampton, and York counties. The Maryland output is still derived wholly from the northern part of Harford county, in the well known Peach Bcjttom area. /"Zstx. — The slates are utilized to a veiy large extent for the production of roofing materials, for which pur- pose they are split into sheets from one-eighth to three- sixteenths of an inch in thickness and trimmed into rectangular slalis varying in size from 3 bj- 7 to 14 by 24 inches. The price of these slabs is usually dependent upon the number retpiired for a "square," that is, a space 10 feet square, or containing an area of 100 square feer. Besides being used for roofing, slates are utilized for billiard tables, mantels, floor tiles, steps, flagging, bluckhoaixls, sinks and stationary washtulis, electrical switchboards, and in the manufacture of school slatesand ]jencils. Incidentally it may be mentioned that there has of late vears been something of a demand for roof- PLATE XIV. — PNEUMATIC STONE SURFACING MACHINE.

In the earlier days of the stone industry hand met h. ..Is ^yere employed almost exclusively in the \vi>rk of ([Har- rying and dressing. The past twenty years has. how- eyer, witnessed the introduction of machinery at a rate which is probably fully comparable with that in any other industry. The old method of drilling and hlast- ino-, formerly applied to all classes of rocks, is now done away with excepting in the very hardest and toughest of materials, or where, as in the ease of the trappean rocks, the material is to lie utilized only for road metal. Eyen where drilling and blasting are now resorted to, it is the custom to drill a series of holes in the line along which it is desired the stone shall break; these holes are then charged somewhat lightly and tired simultaneously. In this way the force of the expl(.)sion is delivei-ed along a considerable surface and the danger of shattering the material through the sudden jar is reduceil to a mini- mum. This process is at present largely limited to granitic rocks which are too hard to he quarried hy means of the channeling machines. The drill commonly employed for this work consists in its simplest form of a steam .■ylindcr. mounted upon a tripod, with the drill attached directly to the piston. Since a flexible ho.se is used to convey steam from the boiler, this form of drill can be carried t,. anv [.art ot thecjuarry. Numerous adaptation; been put upon the market by various niakci-s. mon form is that shown in Plate XIU ( )n soft stone, like sand.stone, or granitic rocks with wel-deve oped 1 • 1 -n 4^ fl,U i-lri(l arc utilized 111 what IS rift and grain, drills ot tlii^ .^|'|" '" ovio ■ «-f , 1 j2 <-r ,. iJift n"'.

One of the earliest of these ma- suitable ^^^ jual■kct^vas the Wardwell channeling chines iip*^ ^^^^^^ which is shown in Plate IX. Various inachiii'^''.' . ^Yi\s have since been made, as shown „ioditicatio»'^ in Plates X, XI, and XII. These later adaptations make it possible to cut: a channel at any desired angle. There were 7-!4 tif these machines of \arious makes rcjiorted ill use during the census yaw. What is known i as the (juarry bar, answering the same purpose as the channeling machine. Imt without the loconioti\'e attach- ment, is shown ill Plate XIII. A niai-hine based on the same principle fiu- undercutting, or gadding, is in common use in the marble (juai'ries of Vermont. A diamond drill machine is iiseil for similar purposes. There were l.");! machines of various makes adapted to this work reported in operation during thecensus year. An attempt has been made to introduce the so-called helicoidal saw f(U' quarrying the softer rocks, as lime- stone and marble. The attempt seems to ha\-e been I only partially successful, except in the larger lime- stone quarries of the ^liddle West, owing apparently to the large amount of labor m-cessary for putting the saw in position and the waste in\Til\-ed in cutting out the corners in which the j^uUeys are to run. The returns from all the quarries report onl_y .32 of these saws actually in use. The saw. as is well known, con- sists of a twisted iron-wire rope, generally three-six- teenths of an inch in diameter, miming over sliding pulleys, the abrading material being either sand or chilled iron, as the case may be. After the stone is removed from the quarry lied it is -sNorked into the desired shape and size by a process depenilent largely upon the hardness of the stone. Formerly a block after being reduced to an approxi- mately rectangular form })y means of hand phig-and- feather splitting, was still further reduced bj' pitching t(.)ols. followed when necessary b}- such implements as the point, ax, pean hammer, and bushhanmier. Pneumatic tools are gradually replacing these hand implements. AVhat is known as the pneumatic surfac- ing machine is shown in Plate XIV. This and the other machines mentioned below are in use in the stone yards and workshops in towns and cities, as well as at the larger quarries, and statistics as to number are not available. Lathes and planers are utilized very exten- sively on the softer stones, and in some of the works on hard stones as -well. Indeed, the production of cylin- drical columns by the old hand method has been almost entirely superseded by the use of lathes similar to those used in turning metals. A monster machine of this type is shown in Plate XV. Specially adapted forms of lathes are also used in turning grindstones at the Ohio sandstone quarries. Planers thus utilized difler so little from those employed in planing metal that they need no special notice here. Attention shotdd, how- ever, lie called to the circular planer which is used in working out curved surfaces. Except on the harder stone, like granite and qnartzite. saws are extensiveh' used for splitting up material into rectangular masses and slabs where smooth, even surfaces are desired. Those most in use are the old time reciprocatino- saws 806 MINES AND QUARRIES. consisting of a band of soft iron set in a frainc a?id fed with sand, chilled iron, or shot, as the case may be. Circular saws are also utilized in some ceases. A circu- lar saw with diamond teeth is occasionalh' employed. In working' slate a steel circular saw with teeth similar to that used in sawing lumber is employed. In han- dling the material in the yards and shops traveling cranes are used much as in iron and steel works. Table .-JT.— DETAILED SUMMARY, BY CLASSES: 1902.

By Story R. Ladd. Hj'draulic cements are of three kinds, Portland oi' artitii'ial cement, natural-rock cement, and Pozzuolana or slag- cement. The last-named class does not fall within the scope of the mining- census, nor does the manufacture of anj- kind of cement, except as it is associated with the mining or quarrying of the raw material; hence the statistics presented in Tables 1 and 8 include only the Portland and natural-rock cement made by establishments mining or ((uarrying the raw material, at least in part. In cases where the raw mate- rial was manufactured into cement by the operator of the mine or c^uarry, the statistics include the manufac- ture, as well as the mining and cpiarr3'ing-, of the raw material; and where a part of the raw material was mined or quarried and a part purchased, the complete mining and manufacturing .statistics are included, be- cause it was impossible to differentiate the statistics chargeable to the purchased material from those per- taining to material mined or quarried. The comparative statistics from 1850 to 1902, inclu- sive, are shown in Table 1. Table 1. — Comparative summary: 1850 to 1903. Number of mines or ijLiarries Number of operators.

The growth of the industrj' has been very great. The inci'ease of production in 1889 over 1880 was nearly 210 per cent, and the increase in 1902 over 1889 was more than 2.50 per cent. In 1902 there were 93 operators, of whom 1 were in- dividuals, 6 were firms, and 8.3 were incorporated com- panies, as shown by Table 8, a detailed summary of the statistics. Of the individual operators, 3 were located in New York and 1 in Minnesota, and of the firms, 4 were in New York and 1 each in Maryland and Minne- sota. The 83 corporations, constituting 89.2 per cent of the operators and owning 91 establishments, or 90.1 per cent of the whole, produced 98.3 per cent of the product. All of the Portland cement was made by in- corporated com]3anies. The statistics for the jDresent census are the most complete that have ever been pub- lished. At the Kleventh Census no statistics in regard to cement production were reported in connection with the mining census, except the estimated quantity and value of the cement product, 7,000,000 barrels, having a total value of 15,000,000. Chpi'tal xtoek of incorporated coinpdnles. — Table 2 presents in detail the capitalization of incorporated companies. The state of Pennsylvania led both in number of com- panies and in capital invested, as represented by the par value of stocks and bonds issued, reporting 39.1 per cent of the entire par value. New York, with 13 corporations, ranked second in number of companies, and Michigan was third, with 10 companies. One com- pany operating in Ohio also owns and operates a plant in Indiana; 1 company operating in Indiana also owns and operates a plant in Kentucky; 1 com2:)an_y in Penn- sylvania operates 2 plants in that state, and another company in Pennsylvania operates 3 plants in that state and 1 in Indiana. In the case of 1 limestone company in Michigan and 1 in New York, producing cement as a minor product, the capitalization is reported in con- nection with the limestone industry. Two companies — 1 in Alabama and 1 in ^Michigan — did not report capi- talization; the former was an English corporation, and the latter was engaged extensively in other business, cement being but a small part of the total.

The salaried em])loyees comprised 14.S g(Mieral officers, «'ho received $347,132, an average salar}- of $2,346; 426 superintendents, managers, foremen, sur- vovors, etc., who recei\-ed $491,671, an a\-erage of $1,154; and 339 clerks, who received $248,711, an average of $734. Of the 13,041 wage-earners 2,o92 were engineers, tironien, and other mechanit's, who received $1,324,121; 3,251 were miners or (luarrymen and miners' helpers, who received $1,440,029; and 111 were boys under 16 years of age, who received $23,499; the 7,587 other wage-earners received $3,541,203. Mining Iwlow ground was reported in the case of 14 mines or (juarries, of which 5 were located in New York, 3 in Maryland, and 1 each in Illinois, Indiana, North Dakota, Ohio, Virginia, and Wisconsin. Boys under 16 years of age were employed in 22 mine.s — 6 in Penn- sylvania, 5 in New York, 2 each in Kansas and Virginia, and 1 each in Alabama, California, Georgia, Indiana, Maryland, Texas, and Utah. Of these mines, only 1, located in the state of New York, reports the employ- ment of boys undergi-ound. The variation in the numbers of wage-earners em- ployed at different seasons of the year is shown in Table 8, which gives the average number of men and boys employed during each month. Taking the industiy as a whole, the minimum number was employed in Febru- ary and the maximum in September, with a steady in- crease from February to September, followed jiy a slight falling off in the fall and early wintei-. The increase in the number of wage-earners for December over the nuiiiher employed in January, 35 per cent, re- rtects the growth of the industry, which was most marked in Mit^higiin, Illinois, and Indiana.

Of the total number of wage-earners 3,031, or 23.2 per cent, were miners or quarrymen; of this class, 2,061, or 68 per cent, received from $1.25 to $1.74 per day. Of the 3,031 miners or quarrymen distributed in Table 3 according to dail}' rates of paj', thei-e were 449, 14.8 per cent of the total number, for whom rates had to he computed, because they were paid by the ton or cubic yard. The total amount paid them was $215,796. Contract mining or quarrying was reported for 11 mines or quarries, located 3 each in New York, Ohio, and Pennsylvania, and 1 each in Ctilifornia, Michigan, and Utah, at rates ranging from $0.18 to $0.40 per ton, except in the case of 1 mine in Ohio, where the rate was $1.25 per gross ton. In addition, 1 establishment in Michigan reported the excavation of mai-1 by contract at $0,055 per cubic yard. Contmct 'iiH/rl'. — Contract work for tunneling, shaft sinking, boring test holes, etc. , was reported by 3 estab- lishments, 1 each in Kansas, Kentucky, and New York. The number of men so emiDloyed was 34, and the amount paid for such contract work was $1(J,627. Supplies, nidterUih^ (ind iiiiHcMcmcoun expenses. — The total expenditure reported for supplies and materials was $9,098,226. As cement is marketed in barrels or bags, the containers constitute quite an item of expense. The total amount reported for miscellaneous expenses was $1,665,520; of this amount, $52,906 was paid by 14 operators — 4 in Penn.sylvania, 3 in Ohio, and 1 each in Kansas, Maryland, Minnesota, New York, Texas, Utah, and Wisconsin — for royalties and rent of mine or quarry and mining plant, and $1,612,615 was expended for rent of offices, taxes, insurance, interest, and other sundries. MecJianical poiver. — The primaiy power employed in the cement industry aggregated 114,092 horsepower, of which 110,650 was owned and 3,442 rented, the latter being electric power. Of the power owned, 93.8 per cent was steampower. Electric motors were em- ployed in the industry of a total capacity of 17,420 horsepower. Product !o)i. — The total production of hydraulic cement by establishments mining or quarrjdng raw material in whole or in part, was 24,655,360 barrels, valued at $24,268,338. Pennsylvania was the largest producer, reporting 9,360,802 barrels, or 38 per cent of the entire product; this state and New York together reported 57.2 per cent of the total production. Penn- .s3dvania produced 51.3 per cent of the Portland cement, and New York 44. 9 per cent of the natural-rock cement. Of the lOl mines or quarries covered by Tables 1 and 8, 54 manufactured Portland cement only and 37 natural- rock cement only, while 10 produced both Portland and natural-rock cement. The 54 establishments manu- facturing onh' Portland cement produced 14,115,121 barrels, at an aggregate expense of $12,655,189; nearly 90 per cent of this product was reported by 40 estab- lishments in the states of Illinois, Indiana, Michigan, New Jersey, New York, Ohio, and Pennsylvania. Among the 51 mines or quarries producing Portland ! cement exclusively there were 13 — 7 in Michigan, 3 in New York, 2 in Ohio, and 1 in Indiana — which reported the manufacture, in the aggregate, of 1,981,415 liarreLs of Portland cement from marl. The marl mined or excavated by these establishments was reported in some 842 MINES AND QUARRIES. cases in cubic yards and in other cases in tons, the quan- titjr reported being 723,385 eubie j'ards and 35!»,277 tons. In ^Michigan the development of the marl cement industry' has been very great; the 7 estaldishments reporting from that state e.vcavated H55,y(i2 cubic yards and 20,000 tons of marl, and produced 1,167,052 barrels of cement. The 37 esta})lishments manufacturing only natural- rock cement produced, in the aggregate, 6,954,704 bar- rels of cement at an aggregate expense of $2,732,514. The entire hydraulic cement production of the United States for 1902, including cement manufactured by companies not mining or (Quarrying any portion of the material, is .shown in Table 4, Table 4-.— CEMENT PRODUCTION: 190L>.

Since 1897, except in 19(10, the annual imports have been below the average of the imports for the entire period of thirteen years, and in 190^ they were approximately on a par with the imports for ls'.)0. Kilns. — The kiln equipment of the 1(»1 establishments included in Table 8 comprised 584 vertical and 4.")1 rotary kilns. As a rule, natural cement rock is calcined in ver- tical and Portland cement mixtures in rotar}' kilns; but 3 establishments in New York and 1 in South Dakota reported the use of 47 vertical kilns in the niaiuifacture of Portland cement, and 1 establishment in Minnesota used 5 rotary kilns for natural-rock cement. Xer cent) to 7 Sulphuric ar-i(] (percent) 2 to 2 7 The process of formation and hardening of the cement is similar in all cases, depending chieHy upon the foi-ma- tion of calcium silicates, which become hydrated and crystallize undei' the action of water. If it were possi- ble to find a natural product containing lime and clay in the right proportions, a cement of the correct Poit- land standard could be made from it by the simple oper- ations of calcining and grinding; but it A'ariation of I per cent from the correct standard greatly reduces the value of the cement. Most of the argillaceous lime- stones of the Tnited States contain a high proportion of magnesia and an excess of clay. If liurned at the high temperature necessary to produce Portland cement, they fuse to a slag wdiich does not ijossess hydraulic projj- erties; but when burned at a heat only sufficient to drive oft' the carl)onic acid, they yield a soft yellow clinker, which, when ground, gives the natural-rock cement of commerce. POItTLANI) CEMENT. IiKjri-d'n'ilis (?,s7_^r/.— The necessary materials for Port- land ct^nient are calcium carbonate (usually in the form of limestone, chalk, or marl) and clay or shale. The relati\(' proportions of the two deptmd upon theii' vary- ing coinptjsition. ^Ihe calcium carbonate should be as pure as possible, except for the presence of ''lay. Magnesia is always present to some extent, ;ind though it is generally agreed that up to 3.5 per cent it is harmless, a larg(> percentage is ol>j(!ctionable. Calcium sulphate in excess of about 2.5 jKTcent is also objectionable, unless a decided oxidiz- ing flame be maintained in bui'ning, as it is liable to be reduced to the sulphide. Both magnesia and calcium sulj)hate are considered especially objectionable in cements that are to be exposed to the action of sea water. In England a comparatively soft chalk is generall}' used; in (Jermany, chalk or limestone. In the United States a larg(> part of the Poi'tland cement is made from the slate-like limestone of the Lehigh valley region, ^rhis material contains rather more clay than is required for a correct mixture, so that a small ])ropoi-tion of pure limesime — usually from 10 to 20 per cent — is iuldetl. In N( w York, Ohio, and Michigiin marl, a soft fresh-water deposit similar to chalk, is generalU' employed, i^'ure limt^stone is used in a few cases only. The chemical composition of certain typictil forms of ctiicium carltonate used in the manufacture of Portland cement is shown in the followino- table: CONHTITUENTM. <'iilciiini onrbonate, ..

In the dry process, now largely used, the materials are ground and mixed in the dry state. Marl and clay are mixed in a plastic condition. Rock crushers, followed by buhrstones, emery mills, tube mills, or Griffin mills, are generally used for the drj- grinding of raw material, and pans with edge I'unners, followed b}' tube mills, for wet grinding. The chemical composition of the mix- ture is constantly tested, and the percentage of calcium carbonate is kept within the 0.5 per cent of that found to be correct for the materials used. B II I'll iiig. — Over 95 per cent of the Portland cement is now burned in rotary kilns. The rotary kiln consists of a slighthMnclined cylinder, lined with fire brick, turning at the rate of one revolution in from one to three min- utes. Fuel oil was formerly used as a source of heat, but powdered coal is now generally employed. The cement material is fed in continuously at the upper end in the form of dry powder, or, in the case of marl and clay, as liquid mud. Descending gradually, it parts with its water, if any, in the upper third of the kiln, becomes heated to redness, loses its carbonic acid, forms small rounded balls which reach a nearly white heat in the lower third of the kiln, and finally issues at the lower end as well-burned black clinker in grains about pea size. When the burning is done in vertical kilns, the dry powder is first moistened and molded into bricks, which are again dried before being fed into the kiln. Accord- ing to Le Chatelier, the following changes take place during the burning: At a red heat the combined water is expelled from the cla};-; at a somewhat higher temper- ature the calcium carbonate is decomposed into carbonic acid gas, which escapes, and lime, which inunediately enters into combination with the silica and alumina of the clay, producing calcium silicates and aluminates. At first, fusible glasses, rich in silica, are formed; l.)y combining with more lime, these gradually become more and more basic, until at last the tricalcium silicate is produced. The iron and alumina also remain in com- bination with lime as an alumino-ferrite. The proper degree of burning is indicated by the formation of a dense gi'een-l)lack clinker. Under- burned clinker is brownish and soft, while overburned clinker is fused and slag-like; long-continued burning or an excess of clay causes the clinker to ''dust" or fall to powder on cooling, the resulting powder show- ing little or no hydraulic properties. Underburned cement is apt to be quick-setting and to expand and crack in hardening; on the other hand, overhurned cement is usually slow in setting and hardening, though it may show excellent tests at long pei'iods. Cement properly proportioned, mixed, and burned does not begin to set in less than two hours after mixing with water, but after the setting begins it hardens rapidly and shows a steady gain in strength, especially when tested with sand, up to several years. It is an almost universal practice to add from 1 to 'Z per cent of ground gypsum to retard the setting. Gr'niAliiij. — Portland cement clinker was formerly ground with buhrstones and bolted through I'evolving screens. At present the Giiffin mill or the German ball mill, followed by the tube mill, is geni'rally used. A degree of fineness, such that H2 to 93 per cent will pass through a No. 100 sieve, is generally attained. Finer grinding can easily be accomplished, if necessary, but is rarely demanded. There is, of course, a point beyond which it is not economical to carry the tine pulverizing of cement, since the same result can be accomplished by using slightly richer mixtures. The numerous tests shown in the I'eports of Govern- ment and private engineers warrant the claim that no Portland cement made in any foreign country eijuals the product of the leading American factories. NATURAL ROCK CEMENT. Of the natural rock cement produced in the United States in 1902, about 15 per cent came from the state of New York; al)out 23 per cent from Kentucky and Indiana, within a radius of 15 miles of Louisville. Ky.: and the remainder largely from Pennsylvania and Illinois. Ri>Ki_'iid(ili; rriiii/iitK. — Of the natural-rock cements the Kosendale cements, manufactured in Ulster county, N. Y., from a natural cement rock known as the Tentac- ulite or water-lime deposit of the lower Helderl)erg group of the New York Geological Survey, are typical. The Rosendale cement industry is the oldest manu- facture of hj^draulic cement in the country. Dating from 1832, the industry has been developed conserva- tively and successfully. The rock deposit is a magnesian limestone, of which two different beds, known respectively as the "light" rock and the "dark" rock, are quarried for cement. Both rocks are hard, compact, and close-grained, the light rock having a steely-blue color, and the dark a duller and deader color and a more shaly appearance. Apparentl}' the light rock contains the more lime and the dark the more clay. After calcination the light rock is yellow, and the dark a redder or dark sienna color. It is a tradition that no good cement can t)e made without a mixture of the two. At Binnewater, Ulster county, the depth of the dark- rock deposit, which is the lower bed of cement rock, is about is feet, that of the light rock is from 10 to IT feet, and that of the unworked strata Ijetween the two is about 12 feet. The dip varies, but is generally about 15 degrees. The general mining scheme is to run slopes 846 MINES AND QUARRIES. to a depth of about 40 tVet, followinj^- the dip of the dark rock, and then to start breasts or headini,>-s in both directions along the strilie. When the headings have been run out to da3dig'ht, to property limits, or to the limit of economical working, the slope is run down -io or 50 feet farther and new headings started. The rock is loaded on cars which are run through the lieadings to the foot of the slope and hauled up by calile. To get at the light-rock deposit, which is overhead, horizontal gaugwa3'S are cut from the gangways in the dark rock through the hanging wall into the l)ed of light rock, and headings are then started in it in both directions, just as in the lower formation, the cars being run through the connecting gangways and up the slope. In chemical composition the liosendale cements are remarkable for the high proportion of magnesia they contain; it varies consideralih' in different Rosendale brands, but the following analysis is typical of these cements as a class:' Silica Alumina Ferric oxide. Lime JIagnesia 1.'4. :!(!

Ldiiisi'ilh- ritni-iitx. — The so-called Loiiis\ille cements are ne.xt in importance to the Rosendale product. An extensive deposit of limestone occurs at Louis\-ille, Ky., forming the bed of tlie Ohio river, and causing the falls and rapids at that place. The first manufacture of Louisville cement began alongside of and in con- junction with the construetioii of the ivouis\ille and Portland Canal around the Louisville falls. ' 4'|je largest plant in the Louisville district is at Speeds, Indiana. The cement rock is of the same geological horizon as the water-lime deposits of New York, J'ennsyhania, and "Wisconsin. A general analysis is aliout as follows: Siliea and inHolulile matter \:^A\ Alumina and iron n.xiilp _ Ci. II Calcium carbiiiiiite (d .

Li charging, a layer of rock is thrown in, then a thin laj'er of anthi-acite jjea coal, then another layer of rock, etc. The fuel consumption is low, the output of cement per ton of coal being (juite high. At Binnewater the kilns are 2^^ feet high and 10 feet in diameter, with a daily capacity of from '.»(.» to ItMi })ai-rels of marketable cement stone, after discard- ing all hai'd-burned clinker' and sorting out the undei-- l.)urned cliidet high and have an inside diameter of 13 feet, with a daily capacity \\\) to -Zi'><) fjarrels. The calcined rock is run through crackers and then screened; the. coarse rock is ne.xt ground in mills, but the finest grades pass directly to the ))arrel packers. The product is packed as it is ground — nearly all of it in barrels. SLAIi CEMENT. The manufacture of hydraulic cement from furnace slag has reacheil consideralile proportions abroad. Init ill this country it is comparatively a new industrv. It is not directly within the scope of the mining census, but it is noticed lirietly because it utilizes;! waste prod- uct of nuned material. It is only occasionally that ores and fluxes employed in blast fui-naees Avill ]ii'odiice slag suita})le for cement, furnace slags as ordinarily produced by casting and -.low cooling being dexoid of hydi'aulic properties. Slag to be used for cement i.^ run off from the furnaces and dropped in a molten state into a trough through which is forced a large stream id' cold water; the slag solidities in vesicles oi- liulibli's. w liich break up into thin, sludl- like pieces. The best grade of such slag has a delicate blue color, and though hard is thin and porous, and hence is i-eadily erii^lied. The rest of the process is extremely simjile. consisting in di-ying tlie slag, mixing it with the ]iroper pi'opiu'tions of slaked lime, and then grinding the nii.xliire to a line powder. The Maryland Cement Company utilizes the slag from the blast fur- naces of the Maryland Sfeid Coni[)an\', at Sparrow Point. .Mil. ( 'iiban ii'oii ores are largely used in these fnniaees w itii oyster shells as flux. I\\ KN'I'IONS.

CLAY (855) CLAY, By Jefferson jNIiddleton. This report covers the operations of the elix}' mining- industry in the United States during- the 3'ear 1902. By far the larger portion of the elay mined is used by tlie miner in the manufacture of clay products. Iiut us the work of -svinning- the clay is such an intimate part of the process of manufacture as to malvc its segregation impossible, only the clay mined and sold as such has been included in the report. The statistics for the clay working industries were shown in the Twelfth Census Report on Manufactures. The clay mining industrj^ seems to have received but little attention at pre^'ious censuses. Statistics were first shown at the census of ISOd, when 5 mines were reported, all in Middlesex county, N. J., with a product \-aIued at $1(J5,660. At the census of 187(1, 1 tire clay establishment was reported from Jackson county, ^Nlicli., with a product valued at $80,000. At the census of 1880 statistics were presented for 9 kaolin mines — 4 in Delaware, 2 iti South Carolina, and 1 each in Indiana, Maryland, and New York — reporting- 23,277 tons of clay, valued at 1200,1:57. The Eleventh Census con- tains no statistics for clay mining as a distinct industry. Clay mining- was carried on in 27 states, but in most of them the industry was of minor importance. In only 6 of the states did the product exceed a value of $100,000, and the product for these states was 68.7 per cent of the total value of products for the United States. The following- table is a sunnnary of the statistics for 1902: Table 1. — iSiniunari^/.- lOOi.

Of the mines, 34 were in New .lersey, 31 in Oliio, and 25 in Missouri. The number in the other states \-aried from 19 in Penn- sylvania to 1 in several of the states. Ill addition to the active^ mines, (!1 idle mines were reported, distriliuted as follows; 12 in Ohio, in Ten- ness(>e, 5 in Maryland, 4 each in Georgia and Pennsyl- vania, 3 each in Colorado, Missouri, North Carolina, and \'irginia, 2 each in California, Illinois, Indiana, Ken- tucky, Massachusetts, and Vermont, and 1 each in jNIichigan, New Hampshire, New Jersey, New York, South Carolina, and West Virginia. There were also 2 mines — 1 each in North Carolina and Florida — at which development worlv onl}' was reported.

It shows that of the 203 operators of clay mines 52 were incorporated companies, of whom 45 reported :ni au- thorized capital stock of $6,947,600. The total num- ber of shares authorized was 660,536, and the total num- ber of shares issued was 341,107, with a par value of $5,275,200. The dividends paid during the year amounted to $59,190. The authorized stock was di- vided into 650,986 shares of c<.)mmon stock, with a par value of $6,272,600, and 9,550 shares of preferred stock, with a par value of $675,000. Of the common stock, however, only 332,377 shai-es (par vahie. S4.t>37.2()()) were issued, while 8,730 shares of preferred stock (par value, $638,000) were issued. The bonds issued were 717 in number, with a par value of $331,()(i(), on which the sum of $18,110 was paid as interest. The onlv states in which companies reported preferred stock were Georgia, Delaware, and New Jersey, while bonds were authorized and issued only in the two last named states and in Pennsyh'ania. In West \'irg-inia bonds to the value of $15,000 were authorized, liut none were issued. In only 1 state (Wisconsin) were assessments levied. (857) 858 Ml^ES AND QUARRIP^S.

E'fivployi^cH and 'inage». — The average number of wage- earners employed during each month in 1902 is shown by states in Table 7. The most active clay mining sea- son was from April to October. This is to be expected when the principal method of mining clay is considered. Probably 90 per cent of the work was done in open pits; this tends to reduce operations in tht; cold months and of wage-earners between the months of summer and wintei- is not :is great as might be expected, considering the fact that the work done is almost entirely above ground. The average number of wage-earners, men and boys, for the whole year was 2,43o. The laro-est number of men employed in any one month was 2,(>2-t in June, while the .smallest was 2,100 in February. The average number of men employed for the whole year was 2,-103. The average number of liovs eni- in inclement weather. The variation in the number - ployed during the year was 30, the highest number CLAY. 85y Of the 2,433 wage-earners of all oceupation«, 871, or 35.8 per cent, received between $1.25 and $1.49 per day; 41)5, or 20.3 per cent, between $1 and $1.24; 330, or 13. G per cent, between 75 and !»'.» cent.s; and 321, or 13.2 per cent, ))etween $i.5u and $1.74. Of the total number, 1,<;4«, or 07.7 per cent, were miners, of wliom 730, or 44.3 per cent, received between $1.25 and $1.41) per day, and 231, or 14 per cent, be- tween $1.50 and $1.74; wliile 27G, or 16.7 per cent, received les.s than $1. The wage-earner,s next in number to niiner.s were re- ported as ''all other wage-earners." Of these there M'ere <;2!.», consisting largely of unskilled workmen or com- mon laborers, as i.s indicated by the low rates shown in the table — 31.)lt, or 03.4 per cent, having been paid from $1 to $1.49 per day. The other classes of occupations were numerically small. The rates of pay of engineers, hremen, and mechanics averaged somewhat higher than the rates for miners, while the rates paid to boys ranged from less than 50 cents up to from $1 to $1.24. Mechanical poioer. — The total horsepower reported for the industry was 4,478, of which 3,942, or 88 per cent, was steam, the remainder being divided between gas and gasoline engines, water wheels, and "other power." Power is used to a less extent, proportionally to production, in the mining of clay than in many of the other mining industries, clay being taken usuallj^ from open cuts, with pick and spade, and without the use of machines. Production. — Table 4 shows the production of clay from 1897 to 1902, inclusive, by varieties. Table 4.— QUANTITY AND VALUE OF EACH KIND OF CLAY PRODUCED: 1897 TO 1H02.

The largest iumil)er of men was employed in New Jersey — 697 for the entire year, 798 in July, and 590 in February. The avertige number of men reported for Pennsylvania was 311 for the whole year, with the largest number in June (338), and the smallest in February (274).

It is possible that the tii;'ures for som(> of tlic years are not strictlj' comparable, because they may include clay sold, in the raw or the prepared state, by those whose principal business was the manufactur(> and sale of clay products and not the production of clay. This table shows that the production of clay increased from 563,115 tons in 1S97 to 1,455,357 tons in l'.»():i, a gain of 892,242 tons, or 158.-4 per cent, while the value increased from $1)78,448 in 1897 to $2,061,072 in 1902, a gain of $1,082,624, or 110.6 per cent. It is probable that the figures for tht' first two or three years reported by the Survey are somewhat below the actual output, because they were collected liy correspondence- -a method by which it takes usually two or three yeai's to secure satisfactory results. While the quantity of the product for 1902 was the largest recorded, l)eing greater l)y 88,187 tons, or 6.5 per cent, than in 19nl, the value of the product de- creased from $2,576,932 in 1901 to $2,061,072 in 1902, a loss of $515,860, or 20 per cent. This decrease in value was due largelj' to a marked decline in the value of prepared tire clay, which showed a (leci'case of 38.8 per cent in quantity and of 79. S per cent in value. Of the 1,455,357 tons of clay mined in 1902, 1,203,369 tons, or 82.7 per cent, were sold without any prepara- tion whate\"er after mining, while 251. '.I88 t(jns, or 17.3 per cent, were prepared at the mine by Wiishing, by grinding, or in some other mannei-. In I'.iol, 74.5 p(>r cent was sold raw and 25.5 per <'ent \\'as prepared at the mine. The a\'erage value of all clay at the mine in 1902 was $1.42 per ton; the value of the raw clay was $1.10, and of the prepared, $2.94 per ton. In 1901 these average values were $1.89, $1.25. and $3.74, respectively.

DESCRIPTIVE. Popularly, clay is any earthy sul)stance which, if mixed with water and molded, will retain its shape after drjdng, and which upon subjection to high temperature loses its plasticity and becomes hard and brittle. Technically, pure clay or kaolinite, which is the basis of all clay, is a hydrated silicate of aluminum, expressed by the formula Al,0,,2Si03, 2H,0. All clay in its natural state contains more or less impurities, the kind and quantity of which determine its character; from purest varieties, called kaolin, claj'S range through all stages of impurity down to a point where the material contains so little kaolinite that it can not be classified as clay at all. Clay is ordinarily classified as kaolin, ball clay, lire clay, vitrified ware clay, and brick clay; there are also slip clay, and paper clay. Fire clay includes clays used for stoneware and for terra cotta, which are reported separately by the Geological Survey. Vitrified ware clay includes the pipe clay reported by the Survey. In the following description of the physical and chem- ical properties of the several kinds of clay, the chemical analysis has been supplemented, wherever possible, by what is called the rational analysis. The ordinary quantitative chemical analysis treats clay as a mixture of oxides, although the elements may lie present in en- tirely different combinations, such as silicates, carbon- ates or hydrates, sulphates, etc. The nature of these combinations is of importance. For example, silica in the form of quartz, which is infusible, will decrease the shrinkage and up to certain temperatures increase the refractoriness; Ijut if present as a component of feld- spar, it serves the purpose of a flux and somewhat in- creases the plasticity. The advantage of the rational anal3'sis is that it resolves the claj' into its mineral com- ponents, affording an insight into the physical propei'- ties — as fusibilitj-, refractoi'iness — of the material. This is frequentl_y a matter of far greater importance than the chemical composition; for instance, two clays of the same rational composition will behave much alike if burned under the same conditions, even though thev may differ in chemical composition. Kaolin. — Kaolin is a white burning, nonplastic, highly refractory residual clay used in the manufacture of china and other wdiite wares; it must be practically free from iron, as a verj' small quantit}' would cause the ware to become discolored in burning. The chief pro- ducing states are Pennsylvania, Delaware, North Caro- lina, and South Carolina. The following is an analysis of a washed sample of the kaolin from North Carolina, which is one of the best known and most widely used.

Bi'/l cliiy. — Ball clay is a white burning, plastic, sedi- mentary clay, used with kaolin to afl'ord plasticity to the t)ody in the manufacture of white ware, and often incor- rectly called kaolin. The distinguishing characteristic of this clay is its plasticity. The chief producers of ball clay for sale are Florida, New Jersey, and Kentucky.

Glass- house supplies, which must be highly refractor}', are made from an especially high grade of this clay. Fire clay is subdivided into flint, or uonpla.stic, and plastic clay.

A. Wheeler, page IS. Bricl' elaij. — Brick claj's are divided into those used for common and for pressed and ornamental brick. Red earthenware, such as flowerpots, is also made of brick clay. Claj's suitable for the manufacture of common brick are located in everj' state and almost everj' county in the Union. Of all claj^s these are usually the most impure, often containing a rather high percentage of lime. Lime in a finely divided state is not harmful; but in the form of limestone pebbles it is very injuri- ous to the finished product, as the process of burning converts these pebbles into quicklime, which is apt to slack, thus breaking the brick, ujDon being exposed to the atmosiDhere. This difficulty is sometimes overcome by passing the clay through a pulverizer, which crushes the pebbles, or by screening it to remove them.

Pressed brick and ornamental brick require a higher grade of clay, the buti" varieties being made sometimes from a refractory or semirefractory clay. Tiie but! color in refractory clay is due to the low percentage of iron; in other clays, notably the Milwaukee clay, from which is made, probably, the best known bufl' or cream brick, it is due to a large percentage of lime, which enters into chemical combination with the iron, thus neutralizing its coloring elTect. Slip clay. — Slip clay is used in glazing low grade products such as earthenware and stoneware. It must fuse at a low temperatui'e and produce a glaze of even color. Theclaygenerallyusedforthispurpose ismined near Albany, N. Y., and hence is known as Albany slip. It produces a dark brown glaze, and is shipped to almost every state in the Union. Paper day. — Paper cla}' is used, as its name indicates, in the manufacture of paper. As clay used for this purpose is not molded or fired, i^lasticity, fusibility, and vitrifj'ing qualities need not be considered; hence any pure white, smooth, gritless clay can be used. Where the cla}^ is suitable in color, but gritty, the grit is some- times washed out. In the United States paper clays are mined in Delaware, Georgia, Maryland, Pennsyl- vania, and Wisconsin.

By JosEi'ii Hyde Pratt. The mining- of a))rasive materials forms a very impor- tant industry among- the minor minerals, on account of their close connection with all manufacturing industries. As a whole, these abrasive materials are but little under- stood, although they are of wide.spread use. No manu- facturing plant, machine shop, blacksmith shop, farm, or household is without some form of abrasive, so that these materials arc perhaps in as universal use as any group of minerals. While the abrasive materials vary widely in character and occurrence, they can readily lie grouped together and considered under one head on account of the similarity of their use. The natural products that are used for abrasive purposes are as follows: Buhrstones and millstones (conglomerate and granite); corundum and emery; crystalline quartz; gar- net; grindstones and pulpstones (sandstone); infusorial earth, tripoli, and pumice; and oilstones, whetstones, and scj'thestones (sandstone and schist). The crystalline quartz included in this report is used ' in the manufacture of sandpaper, scouring soaps, wood- finishing materials, etc., and does not include that used in the pottery and glass industries, and which is included in the report on flint and feldspar. On the other hand, the entire production of infusorial earth and tripoli is included in these statistics because the small production of these materials, although but little is actually used for a])rasiye purposes, does not justify separate treatment. In treating these mineral products under the one sub- ject of abrasives it is not always feasible to give detailed statistics regarding each, as would be done if they were treated separatel}', and proper comparisons between expenditures on ^account of the production of the dif- ferent abrasives can not alwaj's be made, because some of the articles require more elaborate processes than others in their prei:)aration for market. At none of the previous censuses have the abrasive materials been grouped as the_y are in this report. The statistics of mining operations for some of these minerals were re- ported for 1S80 and 1889, but they were not brought together in a single class. At the census of 1880 the classitications of aliiusives were, corundum (emer}'), garnet, infusorial earth, oil- stones, scj'thestones, and whetstones. At the Eleventh Census the classitications were, coi'undum, grindstones, infusorial earth, millstones, and whetstones. In Table 1 are given the statistics for these several classifications for the censuses of 1902 and 1889, and while not comparable, yet they indicate in some meas- ure the growth in the production of abrasive mate- rials for this period. For corundum and emery, and also for oilstones, whetstones, and sc\'thestones, com- parisons of most of the items can be made for the two censuses. Buhrstones and millstones to the A'alue of |>1,425, in- cluded in the statistics for 1902, were quarried at granite quarries; grindstones and pulpstones to the value of $103,066, and oilstones, whetstones, and scythestones to the value of $38,612 at sandstone quarries; and infu- sorial earth, tripoli, and pumice to the value of $1,136 at talc and soapstone mines, all as bj'-products. In these eases the wages and other expenses of production are included in the statistics for granite, sandstone, and talc and soapstone, respective!}'. The production of certain of these abrasives is on the decline, while that of others is increasing, but because of the increase in manufacturing industries the aggre- gate amount of abrasive materials used in the United States is greater than ever before. As their use is limited there could easily be an ovei'production of most of them, but in the aggregate there will be an increas- ing demand from year to year. This will depend prin- cipally upon the growth of our manufacturing indus- tries and the development of our agricultural lands, and with an increase or a decrease in manufacturing espe- cially there will be a corresponding change in the pro- duction of abrasives. The principal change, however, that will be noticed is in the amount of the different kinds of abrasives used from year to j'ear, the produc- tion of some increasing rapidly, others steadily decreas- ing, these variations being due to the introduction of new natui-al or artificial aljrasive products, to changes in methods of manufacturing, and to the use of new types of machiner}', affecting principally the abrasives formerly used for agricultural implements.

Of this amount, *31,3-iy, or 39 per cent, was used in the grindstone industry, and $36,114, or ?>-2J> per cent, in the corundum and emery industry. The miscellaneous expenses amounted to $42,410, of which $^,421 was paid out for royalties and rent of mine and mining plant, and $33,989 for rent of offices, taxes, insurance, interest, and other sundries. Mechank-aJ jxnver. — Of the primar}^ power reported, 2,800 horsepower, or 92.2 per cent, was steampower applied l)y 71 steam engines. Forty-one steam engines, having a total of 1,235 horsepower, were used in the grindstone and pulpstonc industry. The next largest number of steam engines, 13, was reported for the oil- stone, whetstone, and scythestone industry, but these aggregated only 185 horsepower, while the 7 steam en- gines used in the garnet industry aggregated 420 horse- power, and the 7 in the infusorial earth, tripoli, and pumice industry had a total of 410 horsepower. Eightj'- eight horsepower was generated by 7 gas or gasoline engines, of which 3, having a capacity of 80 horsepower, were used in the corundum and emery industry, and 4, having S horsepower, in the oilstone, whetstone, and scythestone industry. In addition there was 1 electric motor, having a capacity of 5 horsepower; this was used in the infusorial earth, tripoli, and pumice industr}^. ProdudioiK — The value of the production was $1,177,711. an increase of $541,052 over the value re- ported for 1889, which was $636,659. Of the particular abrasix'es, grindstones and pulpstones show the largest increase. $227,844 in \-alue, over the production of 1889. The second largest increase was in oilstones, whetstones, and scythestones, the value of which was $113,968 in 1902, an increase of $80,988. Oilstones and whetstones are not always finished at the quarries, ))ut are in some instances shipped to a central plant and there prepared for use. When the finishing process is not conducted immediately in con- nection with the actual quarrying, the \alue of the crude product is given in Census reports. In the reports of the United States Geological .Survey, on the other hand, the finished value is given, for the reason that, with the exception of Arkansas novaculite, this material would not be marketable in its crude state. Were the finished value to be taken in every instance b}' the Bureau of the Census, the total jjroduct for oil- stones, whetstones, and scythestones would be increased b}' §107,794, and the production would rank as second instead of third among abrasive materials. In order to show comparativel}' the value of the annual consumption of each abrasive used in the United States, the value of the domestic product and of the imports reported since 1880 are given in the following table. The statistics are compiled from tables of the United States Geological Survey published in "' Mineral Resources of the United States."

ABRASIVE MATERIALS. 877 An eighth might be added — the Peninsula grit — a hard and coarse grit, used for grinding wood pulp. In addition to these grades of stone, a grit known as Euclid stone, which contains about 7o per cent of tine silica and 30 per cent of cla}', is used for whetters, prin- cipally in cutlerj' works, for polishing out the scratches made by the ordinarj^ grindstone. The production is small, but important. It maj^ be well to mention here the grades of grind- stones that are imported into the United States, as thc}^ are used for special purposes for which the_v seem to be particularl}' adapted. A grindstone made from a coarse, hard sandstone is imported from Bavaria, and is used particularly for razor grinding. A tine, hard grindstone, called the Craigleith, is imported from Edinburgh, and is used for special purposes in the glass trade. Although sandstone suitable for the manufacture of grindstones is not uncommon, the variet}' adapted to the manufacture of a pulpstone is somewhat rare. A considerable demand for pulpstones rose when paper began to be manufactured from wood pulp. In this manufacture a stone is required that can be run in hot water. The Peninsula grit obtained from Peninsula, Tippecanoe, and Empire, Ohio, if carefully selected, ought to make a good pulpstone, which should easily compete with that imported from Newcastle-upon-Tyne, England. The natural grindstone manufactured from sandstone was formerlj' in universal use in all kinds of manufac- turing plants and in the household, but there has been introduced successfully^ during the past ten years a grindstone made from emerj' or corundum. While at the present time only the smaller sized grindstones for household use are made of these materials, it is possible that in the near future large wheels will be made that will rival some of the larger grindstones. Oilstones, whetstones, and scytliestones. — The terms oilstone, whetstone, and scythestone are used some- what ambiguously, and often the same stone when used for one purpose will be called an oilstone, and when used for another purpose a whetstone, or even a sc3'the- stone. The term oilstone has come to be applied to all stones used for sharpening mechanics' tools, for the reason that it is necessary to use oil on most of them to prevent the stone from becoming hot and thus heating the tool, and also to prevent the small particles of steel that are ground off the tools from entering into the pores of the stone. A considerable change from one census to another is noticeable in the oilstone, whetstone, and scythestone industrjr in respect to the stone that has the greatest use. While the sale of oilstones and whetstones has increased, or at least held its own, in the United States since 1889, there has been a considerable falling off in the sale of sc3'thestones. This is undoubtedly due to the small number of scj'thes, sickles, etc., used at the present time, these having been lai-gely replaced by im- proved agricultural machines and implements. Scythe- stones are now used in quantity' only in those states or countries into which the improved agricultural machines have not yet been introduced. Thus, while the produc- tion of scytliestones in the United States has remained about the same, it has become necessary to seek a mai'- ket for them in foreign countries, and a considerable proportion of the production is exported. The whetstone producing rocks are all sedimentary in origin, and include (^uartz-mica-schist, sandstone, novaculite. and intermediate rocks. These are found abundantly in various localities, so that there are prob- alily but few countries which have not within their bor- ders a supply of some kind of stone suitable for making whetstones. Although the material for manufacturing- whetstones is so common, onlv those quarries which produce stones of superior quality and have the great- est advantages for manufacturing and shipping can survive the competition in the trade. This is of course the reason the production of whetstones is confined to a few localities. Occasionally- a stone is found of exceptional (juality, as the novaculite of Arkansas, for which there is a large demand, although the price may be much higher than that of other whetstones. At the present time the domestic supply of Avhetstones is ob- tained from Arkansas, Indiana, Ohio, New Hampshire, and Vermont. There is undoubtedly considerable whet- stone material utilized in other states, but those men- tioned are the only ones that have produced this abrasive for the market. At the whetstone quarries in Arkansas, which are in Garland and Saline counties, principallj' at and in the vicinity of Quarry or Whetstone mountain. Garland county, there is obtained the novaculite (sandstone) from which is manufactured the best and most valuable natural oilstone or whetstone on the market. The qual- ity of the rock varies greatly, even in different parts of the same quarrv, but two distinct types of stone or grit are recognized, which are known on the market as the Arkansas and Washita. The latter is less dense and much more porous than the Arkansas. Both of these types are divided into two grades, known as soft and hard. They are used pj-incipally in the form of small wheels, oilstones of different shapes, and points such as are used b}' engravers, surgeons, carvers, dentists, jew- elers, watchmakers, and diesinkers. The sandstone of Orange county, Ind., furnishes a whetstone known as the Hindostan or Orange stone, which is quarried in French Lick and Northwest town- ships. The stone is fine grained and is used for oil- stones. It is considered the best low priced sharpenino- stone for mechanics' tools. A considerable quantity of this stone is now being exported. At a number of the sandstone quarries in Ohio from which grindstones are obtained, principally at Berea, in Cuyahoga county, and at Grafton, in Lorain county. 878 MINES AND QUARRIES. a grade of stone is found suitable for whetstones. This stone makes a scythestone that does good work, but it does not stand transportation so well as the scythestone made from schist. At Euclid, Cuyahoga county, is a fine grained sandstone from which a considerable num- ber of oilstones are made. The well-known Deerlick oilstone is made at Chagrin Falls, in the same county, from a fine grained sandstone. Since the introduction of this stone a few j'ears ago its production has in- creased considerably each year. In Cortland county, N. Y., near Labi-ador Lake, a sandstone similar to that quarried in Ohio is found. It is known as Labrador stone, and is used to a limited extent in the manufacture of whetstones, although no product was reported as quarried in 1902. In Haverhill, Grafton county, N. H., and near La- moille, Orleans county, Vt., there is a quartz-mica- schist from which are manufactured the celebrated Indian Pond, "White Mountain, and Lamoille scythe- stones. These schists are variable in their structure, so that only portions or l)ands of them can be utilized. The cutting quality of the stones varies with the com- pactness of the schists and the percentage of quartz or grit contained. There are two principal grades of stone found at the New Hampshire quarries, which are known as the Indian Pond and the White Mountain. Both of these stones come from the same quarry. The White Mountain is more compact and has a finer texture, and the Indian Pond includes the more laminated varieties of the schist. The name Indian Pond was used as earlv as 1820 for a stone obtained from a stratum of schist about 7 miles south of Pike Station, near a jjond known bj' the above name. The stones from the quarries at Lamoille are sold imder the name of Lamcjiile stones. At Lisbon, Grafton county, ><'. H., there occurs a fine grained quartz-mica-schist of a bluish cliocolate color, which furnishes a stone known as the chocolate whet- stone. It is a medium hard st(jne and is especially adapted for leather and skinning knives, and it is also used extensivelv for sharpening cloth cutters' tools, kitchen and carving knives, etc. Biihrst per cent of garnet. In Delaware and Chester counties. Pa., a garnet oc- curs in small crj'stals and fragments thicklj^ dissemi- nated through a gneiss which is badl_y decomposed. A considerable product, leported from Delaware counts-, is known on the market as rose garnet. CrystuUine (jmirfz. — The production of crystalline quartz that is included under the head of al)rasives, is that which is used in the manufacture of sandpaper, scouring soaps, and as a wood finisher. In addition to these uses there are large quantities of quartz sand used in the stonecutting trade, especially by the marble workers. A small amount of quartz is pulverized, and sold under the name of tripoli. Of the production re- ported for 1903 the larger amount was used as a wood finisher, and was obtained from Connecticut. Most of that used in the manufacture of sandpaper was mined in Pennsj'lvania. Infusorial earth and tripoli. — Among the abrasives, infusorial earth and tripoli formed but a small pro- poi'tion of the production, and of the amount produced less than half was actually used for abrasive purposes. Under the head of infusorial earth and tripoli are included all porous, siliceous earths of organic origin, such as infusorial earth, diatomaceous earth and tripoli, and also a siliceous material which is the residue from an impure siliceous limestone by the leaching out of the calcium carbonate. The material produced in 1902 was from California, Georgia, Mar^dand, Missouri, New Hampshire, New York, and Virginia. Pumice. — The production of pumice in the United States has been very erratic during the time for which statistics of this material have been published, although commercial deposits are known to occur in large quan- tit3% especially in Utah and Nebraska. On account, how- ever, of the distance of these deposits from the rail- road, and from the large markets, they are not able to compete with the pumice imported from Lipari, Italy, which is shipped largely as ballast, and which, after being ground and bolted, is sold in New York at from 2 to 2-|- cents per pound. These Lipari dejDosits supply almost the entire demand for pumice. During 1902 the entire production of pumice in the United States was from the Nebraska deposits, and was used largely in the manufacture of soaps and scouring powders. Corundum and emery. — The natural abrasives that have the highest abrasive efiicienc_y are corundum and emery, and there is an increasing demand for these, which is due largely to the increase in manufacturing, especially of agricultural machines, but also to the improved methods that have been devised for making emery and corundum stones and wheels of all shapes and sizes. These abrasives, manufactured into wheels of various sizes, have replaced, to some extent, the suialler grindstones in manufacturing establishments. They have also been manufactui'ed into oilstones and whetstones, and have successfully' competed with the natural product, although selling at a higher price. With the exception of certain emery wheels made by the silicate process, and used for saw gunmiers, no large emery wheels have as j'et been made. Uven if large vitrified emerj' wheels could be made, it is a question whether their cost could be lowered sufficiently to per- mit them to enter into competition with the grindstone, and also whether the emerjr stone would do as satisfac- tory work as the grindstone for certain kinds of grinding. Of the corundum and emer}' used in the United States about one-half is produced in this country, the remainder lieing obtained from the Turkish and Grecian emerj' mines, and from the Canadian corundum mines. There were but a few tons of corundum produced in the United States in 1902, the production of this type of abrasives being almost entirely of the emery variet3\ Corundum was f ormerlj' regarded as occurring sparingly in nature, but it is now known to have a rather wide occurrence and to exist in commercial quantity in many localities. With the known occurrences of this mineral in this country there should be no difficult}' in such production of it as to fullj' satisfy the markets' demand. Competition with the Canadian corundum will be strong, and if there is a decrease in price, the location of the deposits for easy mining and suflicient railroad facilities will need to be very favorable if they are to be profitably worked. The value of corun- dum in 1902 was from 7 to 10 cents per pound when cleaned and sized. Emeries varied in price from 1 to 5 cents per pound. The more promising deposits of corundum in the United States are as follows: In North Carolina, at Corundum Hill, Macon county; at Sapphire, Jackson county; and at Brick creek, Claj- county. In Georo-ia, at Laurel creek, Ralnin county; and in ^lontana, on the headwaters of Elk creek, Gallatin county. The emery deposits are near Peekskill, N. Y., and at Ches- ter, Mass., the latter furnishing the most of the emery produced in the United States. During 1902 there was also a small production in Montana. 880 MINES AND QUARRIES.

BORAX BORAX. By Joseph Steuthkks, Ph. D. The first commercial production of borax in the United States was in 1864, when 12 short tons were mined in California. Since that year the production has fluctuated from nothing- in 1N()9, 187(), and 1871, to 19,11:2 short tons in 1902. I'p to the present investi- gation borax has never been separately treated in the census of mines and mining. Table 1 is a sunmiary of the statistics for 1902. Table I. — Siiinmnrii: lUO.!.

This acid, represeilting a manufacture, is not reported by the Census. There were onlj' 6 productive mines or quarries in 1902, and these were not widely separated geograph- ically. Four were in California, and 1 each in Nevada and Oregon. Each company operated a single mine only. An average of a):)out 25 wage-earners for each mine is shown. For the industry as a whole a total average for the year of only 1(17 salaried employees and wage-earners is reported. Compared with the amount paid in wages and salaries and for miscellaneous expenses, the cost of .supplies and materials appears largtr. Si:: mines were idle in 190::! — 3 in California, 2 in Nevada, and 1 in Oregon — and at 1 mine in California development work was carried on.

Kefining, however, is too closely related to mining to allow of satisfactory segregation. The par value of the total amount of capital stock authorized for these companies was it^o, 17.5,000. repre- senting .S23,750 shares of both common and jiref erred stock. Shares to the numlier of 822, 25(), with a par value of $3,025,000, were issued. Of these 57:^,250 shares were of common stock with a par \'alue of $2,775,000, and 250, OOO shares w(>re of preferred stock with a par value of $250, ooo. All the preferred stock authorized was issued, as was all Itut l,5o(.l shares of the common stock. There was paid $231, (iOO ,in diA"i- dends on the common stock issued. Tliis is equivalent to 8.35 per cent on its par value. No dividend was paid tipon the preferred stock. There was no lionded indebtedness. Ehipl(iij<'i_'x innl iiyijjcs. — The average number of wage- earners employed during each month of 1902, and the (887) 888 MINKS AND QUARRIES. daily rates of pay, are shown in Table 6. The inipor- tanee of this industry is not to be judged by the nuniber of men to whom it gave employment, only 174 at the maximum, during- the cool months of the year. In summer, from June until Septeml)er, the heat in the southeastern counties of California does not permit active operations, which as a consequence are reduced to a minimum. On the coming of cooler weather, how- ever, operations are at once resumed, as appears frou) the number of men reported employed in September and October. Here relativelj- high rates of pa\- are shown. Fifty per cent of the engineers received from $3.25 to $3.49 per diem; 3 of the 6 mechanics got above $3. .50 per diem. Over 71 per cent of those classed as miners or quarrj'men received from $2. .50 to $3.24 per diem. All of the miners' helpers received from $2.50 to $2.74. Of "all other wage-earners" none was paid less than $1.50 per diem, and more than two-thirds, or 07.4 per cent, received from $2 to $3.24. MrclianlciiJ power. — Mechanical power to the amount of 338 horsepower was reported. Two hundred and live horsepower were furnished by 5 steam engines, 123 horsepower bj- 11 gas or gasoline engines, and 10 horsepower ))y 1 water wheel.

To sefiarate ^vo(l]d reveal the operations of single operators. Since lS(J4, when the first production was reported, 15^1,354 short tons of borax have been produced in Cali- fornia. T^his is pi'actically the production for the wdiole United Htates. Prior to 1890 the number of short tons produced annually had pa.ssed the thousand mark only in 1S75, 1876, 1884, 1886, 1887, and 188S. In 1SS9 the production sank slightlj' below this mark, only to rise with a Ijound in 18'.»0 to 3,2()1 tons, the greatest up to that time. Fr(jm then until 19m(», with the exception of 1893 ^vh(■n there was a temporar}' setback, it gradually increased to 25,837 tons. In 1901 a production of 23,231 tons was rcpoj'ted, and in l'.to2, ll»,142 tons, exclusive of the 862 tons of boric acid reported by the Geological Survey. The decrease in output for these j'ears is apparent onh% for it must be borne in mind that the figures of production are for both crude and refined, and that the proportions of each maj^-ary greatlj' each year. The tendency of late years has been to do as much refining or concentrating as is jiossible at the place of production. Thus in 1902, while 43,010 short tons of crude ore were mined, 40,410 tons of this received some treatment at the mines, making 16,542 tons of I'etined product, which, with the remaining 2,600 tons of crude, comprise the 19,142 tons reported.

This concei-n owns or controls borax lands and refineries in the United States, England, France, Chile, Peru, and Turkey. The future of the borax industry indicates an increased demand for borax and boric acid, as well as an increase in the number of industrial purposes to which these and their compounds are applicable. At the present time the various industries in which boron compounds are used include the manufacture of earthen, china, and glassware, enameled ironware, smelting, tanning, calico printing, cement making, color manufacture, bleaching, soapmaking, and meat packing. Boron compounds are also used in laundries and for many household, toilet, and surgical purposes. There has been considei-al.)le discussion as to the use of boric acid as a preservative for food, and the pre- ponderance of the evidence seems to be in favor of its employment in small quantities as an entirely harmless preservative, but only a small proportion of the total supply in the world is utilized for this purpose.

DESCRIPTIVE. Historical. — The occurrence of borax in the United States was discovered in California by Dr. John A. Veatch, Januaiy S, 18.5(). Having boiled a small quantit)' of water from Lick Spring (then known as Tuscan Spring), Doctor Veatch noticed that, as the water cooled, crystals formed and adhered to the .sides of the vessel. These crystals proved later to be sodium biborate, or borax. Shortly afterwards Doctor Veatch found small, c|uantities of borax at the mouth of the Pitt river, in Shasta county, and traces of this salt in numerous springs in the Coast Range mountains; but it was not until September, 18.50, that he dis- covered the extensive marsh deposits on the eastern side of Clear Lake, in Lake county, which subse- quently furnished a large share of the borax produced in the United States. The year 1864 witnessed the beginning of the borax industry in this country. In that year 12 short tons (24,301 pounds) of borax were obtained by evaporating the saline waters from Borax Lake, adjacent to and connected with Clear Lake, in Lake county, 80 miles north of San Francisco. Later the waters of the lake were enriched by the addition of crystalline borax col- lected from the alkaline marshes surrounding the lake. Until the early seventies, the output of borax in Cal- ifornia was obtained solely from the waters of Clear Lake and other lakes in the state, but after that time the discovery of large (piantities of pure liorax in man}' of the alkaline marshes in eastern California and west- ern Nevada, caused the abandonment of the lake refin- eries and the erection of new plants, notably near Columbus, Nev. ; at Searles marsh in the Amargosa valley; and at the mouth of Furnace creek in Death Valley, California. Despite the difficulty and great cost of transporting the refined product b}- teams 1(J0 miles to the railroad, the refineries continued in suc- cessful operation for several years, until the relatively large increase in the domestic output, together with the increased imports from Italy, so reduced the price that the working of the marsh deposits became no longer profitable and the refineries were closed down. About the year 1890 it was found that the borax cru.st on man}^ of the marshes had been formed by the leachings of beds of calcium borate (borate of lime) in the Tertiary lake sediments in that region. Owing to the large extent of these bedded deposits, which possessed also the double advantage of containing a purer grade of mineral and of being more easily accessible than the marsh deposits, the borax industry as it existed at that time was revolutionized. A mine was started on a bedded deposit of from G to 10 feet in thickness at Borate, 12 miles northeast of Daggett, (Jal. , in San Bernardino countj^, and a refining plant was erected by the Pacific Coast Borax Company. This company was organized in 1888, and at the present time is the chief producer of borax in the United States, as well as the producer of a large part of the output of boric acid. The ore at Borate consists of colemanite (a calcium borate mineral) in large masses more or less connected \>^ stringers and bands in a bedded deposit of from 5 to 30 feet in thickness, interstratified in lake sediments. The great value of this deposit led to extensive pros- pecting in other parts of the state, Avhich has resulted in the discovery in Death Valley of enormous quanti- ties of colemanite reported to exceed greatly in value the deposit at Borate. Both at Borate and in Death Valley the deposits are of similar occurrence. i)eing contained in a regular stratum interliedded with semi- indurated sands and clays which comprise the bulk of the strata. These beds are regarded as of Tertiary age, and are supposed to have been deposited from inclosed bodies of water. Large plants for the concen- tration and refining of the crude (.)re have ])een erected in California: At Alameda, near San Francisco (inop- erative during 1902), at Marion, and at Daggett. The largest borax refinery in the United States, however, is at Bayonne, New Jersej'. Reolew of the l)orn:i' industry duriiuj 1902. — There were 4 companies engaged in the borax industry in C'alifornia during 1902 — the Pacific Coast Borax Com- pany, the American Borax Company, the Western Borax Works, and the Frazier Borate Mining Compan}". The Pacific Coast Borax Company, continued to supply a sufficient quantity of borax to satisfy the requirements 890 MINES ANT) QIIARIUES. of the market; and apart from its operations at Borate, prospectino- work for otlier colcmanite deposits has lieeii carried on in Death Valley and much additional property has been acquired. The deposits in Amargosa Valley were carefully examined and large sample lots' of ore were transported by traction engines to Manville. lOd miles distant, and thence by rail to the refinery for testing the quality, in order to determine the value of the property. The large borax retinery at Bayonne, N. J., was destroyed by tire in April, l'.t(.»2, but has since been entirely- rebuilt. The American Borax Company, is under the control of the Standard Sanitary Company-, of Pittsbui-g, Pa. The plant of this concern at Daggett has been greatly extended by the addition of two 2(),(i(i0-gallon tanks or digesters for the treatment of the crude material from the adjacent nuid deposits by the sulphuric acid process, which is referred to in detail later in this report. The enlargement of this plant has greatly increased the out- put of boric acid concentrates, and the results have been so satisfactor}- that a furtiier extension of the plant at Daggett is contemplateci. A new retinery is in course of erection at Pittsburg, to which ^^•ill be shipped the concentrates from Daggett for the final refining. The mines of the A\'esterii Borax Works are located in Inyo county, and those of the Frazier Borate Mining Company in San Bernardino county. Apart from the output of the above-named concerns, a small quantity of borax has been olttained from the marsh deposits in California and Nevada, but tlie total amount produced from tliese scattered sources has been of so little comparative importance that the borax mar- ket was in no way alfected. During the past few years Oregon has contributed to the domestic supply a small quantity of >iorax from the marsh deposits in Harnej' count}'. The output has averaged about -ioti tons annually except in 1902, when 120 tons were reported, as the mining operations had gi\eu way greatly to development work. The chief borax producer in this state is the Eosc A'allcy Borax Company, controlling 2,00(1 acres of rich marsh land near I^akc Alvord in the southeastern pai't of Ilai-ney county. The total area of the deposit, whi(;h is south of the lalvc. aggi'cgatcs apprf)ximately 10,0(>0 acres. The ground is IcacI and treeless, and is incrusted with a layer several inches thick containing in addition to sodium borate numerous other salts of sodium. Dui'ing the long summer months the loose surface deposit is slioveled into small heaps, and issulis(Kpieiitly rej)laced with a second incrus- tation within a coiupai-atively shoi't period of time. The stock of crude material collected during the sum- mer is sufticient to enal)le the retinery to continue in operation throughout the entire year. The crude min- eral, containing fi'orn 5 to 2(1 per cent of ))oric acid in combination with a sodium })ase, is shoveled into tanks containing boiling water to which is added a |)i'oper quantity of chlorine gas or sulphuric acid to decompose the alkali salts anfl thus liberate the boric acid. After a treatment of twenty-four hours in the tank the clear supernataTit li((uor is withdrawn to the crystallizing vats and allowed to cf)ol, whicli causes the Ijoric acid to separate in the form of crj'stals, leaving a mother li(luor, which is used repeatedly until it contains suffi- cient sodium salts to warrant a s(>parate treatment. Ocriirivinv. — The principal minerals containing boron are as follows: Sassolite, boric acid (H.iBOj); borax (tincal), sodium biborate (Na.,B,,Oj.l(>II,,0) ; ulexite (boronatrocalcite) (CaNaB.O,j.sH.,0) ; colemanite (im- pure varieties, priceiteand pandermite), calcium borate (Ca„B„0,i..")H.,()); and boracite (stassfui'tite), magnesium borate (2Mg,Bj(),,-,.^IgCl,), Boron is also a constit- uent of se\'eral common silicate minerals, notalily tourmaline and • datolite. Borax, sodium biborate (Na.,Bj();.l(lll.,0), is the only important salt derived from boric acid. It occurs native in California, Ceylon, and Thibet, and from the last-named place it is obtained in tli(> form of tincal, an impui'(> crystalliz(>d liorax con- taining calcium and magnesium sulphates and chlorides and a greasy substance which is added presumably to protect the crystals from efflorescence and breakiige. The tincal is purified liy dissohing in warm water and adding limewater and calcium chloride in order to pre- cipitate the grease as a lime soap. After filtering, the pure crystals of l>oric acid are obtained by evaporating the solution. PJn/s/rdl ii nil rli, iii ii-itl i-Ini riij_-fi'r,'stii-!<. — Several forms of borax ai'e used in industrial, medicinal, and laboi-a- tory processes —the principal one being prismatic sodium borate (borax, NaJ\0_.l()II„0). There is a second variety called "octahedral 1»orax" which contains five molecules of water of crystallization (Na.3B^0..5H.^O), forming octahedral crystals. The latter variety, unlike prismatic Ijorax, becomes ()pa<(ue upon exposure to moist air and is converted by the absorption of water into the prismatic form. A property of molten bomx of gi'eat utility in ana- lytical research is that of dissolving various metallic oxides. therel)y forming ti-ans))arent glasses of chai'ac- teristic color's. By making a borax bead on a loop of platimun wire held in a blowpipe tlame, and dissolving therein the substance under examination, th(> presence of cei'tain ujctals is easily distinguished. Borax is also of great value in assaying goki anil sil- vei' ores, being used to dissolve and remove the base metals from the metallic h^ad l)utton containing the gold and silver of the sample of ore tested. Vhis property of dissohing oxides is utilized also in soldei'ing and brazing metals that are oxidizable by heat; the molten liorax absorbing any oxides formed whose presence mechanically would prevent the close adhesion of the metals so necessary for a propel- weld or soldered joint. .'Vmong other impoi-fant uses are as a constituent of sti-ass or jiaste for making glass and en;unels; as a o-laze BORAX. 891 for line earthenware; in combination with .shellac as a varnish for stiii'ening felt hats; with casein as a substi- tute for gum arabic, and (on account of its antiseptic qualities) as a household soap; as an inoredient of various cosmetics; and as a solution for (•l(>ansino- the hair. Boric acid (H3BO3) (old name boracic acid): In Tus- cany the vapors escaping- from the hot springs and fi'om openings in the ground (fumaroles) contain boric acid, and in some places this substance is obtained as crystals hj the evaporation of water from these fumaroles. The crj^stals or crusts produced naturally form the min- eral sassolite. The crystals of boric acid arc white in color, laminated in structure, and possess a mother-of- pearl luster. They dissolve readily in hot watei' though very slightly in cold. Upon being heated to 160 C. they lose one-half the water of crystallization and become transformed to pyroboric acid (HjB^O;). At a red heat all of the water is expelled and boric anhy- dride (BoOg) results, which, even at- high temperatures is stable and nonvolatile, and for this reason it is able to decompose nearly all of the metallic sulphates, form- ing when fused with them, metallic borates. Fused boric anhydride when cold resembles ordi- nary glass in transparency, hardness, and brittleness. The chief uses of boric acid are in the manufacture of borax; in making colored glazes for the decoration of iron, steel, and other metallic objects; in enamels and glazes for pottery; in the manufacture of flint glass and strass or paste from which artihcial stones are cut; in making Guignet's green; as an antiseptic in medicine and surgery; and as a preservative for fish, meat, milk, and other foods. The principal methods used in the manufacture of boric acid are thus described: The chlorine or Moore procesa. — In this process, which is used to some extent in England, the crude colemanite in powdered form is suspended in water and heated to 70 C. ; then chlorine gas is passed into the liquor and reacts on the colemanite. forming boric acid, calcium chloride, and calcium chlorate. The greater part of the boric- acid crystallizes out upon cooling and is subsequently purified by repeated crystallizations. The residue solu- tion, called mother liquor, is used many times until the accumulated calcium salts begin to separate out in the form of crystals. The hydrochloric acid procem. — The mode of pro- cedure in this process is as follows: Two parts by weight of hydrochloric acid and four parts of water (the volume of the latter being kept constant) are used, in which the calcium borate is boiled until dissolved. The ))oric acid is then crystallized out of the cooled li(|uor, leaving the calcium chloride still in solution. Hefoi'e the crystals are in proper condition for packing and ship- ping, an additional treatment is necessary, which con- sists of draining, "whizzing," and washing with cold water, concluding with a second and final "whizzing." In (iermany the hydrochloric acid jjrocess is used to extract the boric acid fi'om the boracite contained in the famous Stassfurt ,salt deposits. The material is crushed and treated with hydi-ochloi-ic acid, the result- ant pasty mass is dissolved in l.)oiling water and the solid material separated and removed bj' filtration or d(>cantation; the- clear solution is then crystallized in iron tanks, yielding pure crystals of boric acid. The chemical reaction involved is (2Mg,,BjO,r,), MgClaH- 12HCl+l.sH,0=7MgCl,+lt;R,HO„. The Hnljihirri.c arid procenx. — In this process calcium borate is treated with sulphuric acid, the reaction yield- ing soluble boric acid and precipitated calcium sulphate. The boric acid is obtained by leaching with hot water, the solution so produced being concentrated by evapora- tion until the crj^stals of boric acid separate out from the solution. In California the process is slightl3^ modi- tied. The borate mud is boiled in huge tanks with water containing sulphurous acid, which decomposes the calcium borate, thereby liberating the boric acid in the solution and leaving the calcium in the form of insoluble calcium sulphate. As before, the boric acid is dissolved by leaching with hot water, which, how- ever, extracts also a small quantity of other soluble salts. For this reason fractional crystallization is neces- sary HI order to obtain a fairly pure product. In a few works the insoluble calcium sulphate is separated and removed by passing the muddy solution from the tanks through Klter presses. The sulphuric acid process is sometimes used to de- compose the boracite of the Stassfurt deposits, and in this case Epsom salt is obtained as a by-product from the magnesium sulphate contained in the mother liquor, according to the following chemical reaction: (2Mg3B,0,,), MgCl, + TH,SO, + 18H,0 = TMgSO, + 2HC1+16H3BC\. TJie ariiiiioriia jiroce.-^K or higot process. — Boric acid is produced by heating in a closed vessel 100 parts of colemanite and 150 parts of ammonium sulphate. The product of the first reaction is ammonium borate, which is later decomposed into anmionia and boric acid. The ammonia is condensed and collected, and the boric acid is dissolved from the residuum by leaching with water and concentrating the resultant aqueous solution until crystals of boric acid are formed. The crystals are then removed, washed with water until free from adherino- mother liquor, dried, and packed for shipment to the market. At times the crystals are ground to a fine powder before being packed and shipped. Tlie inaniifacturi' nf liorax from hirie acid. — The process generally used to make borax from boric acid is briefly suuunarized as follows: Equal quantities of crystallized sodium carbonate and water are heated by steam in a lead-lined vessel, and to the solution thus obtained sufficient boric acid is gradually added to com- t)ine with the sodium carbonate and form the borax salt (NajB^O,), lOHgO. Another process is to prepare solu- 892 MINES AND QUARRIES. tions of ammonia, sodium nitrate, and ))oric acid in the proportions of two, one, and two, respectively. By heating- this mixture and dissolving in water, borax and ammonium nitrate are formed. In both of these cases the crystals of borax are ultimately obtained I)}' the evaporation of the solutions containing the borax salt. The inanufactuvc to disin- tegrate physically^ into a sand-like product called "flour," which is removed when cold by screening, and is sacked and shipped to the Bayonne refinery. One disad\'antage of the separation of the colemanite by heating in a furnace is that an}' pandermite (the compact variety of the mineral) prc^sent in the ore is not art'ected by the heat, and is c(jns('(juently left in the waste material reinaininy in the screens. At times the waste equals in quantity one-half of the "flour" product. The conversion of the colemanite into borax at the Bayonne refiner}' in New Jersey is made by decompos- ing the calcium borate with sodium carbonate, leaching out the sodium biborate with water, yielding a solution which is separated from the insoluble calcium carbonate by passage through a filter press at a pressure of from 50 to 100 pounds per square inch. The clarified .solu- tion is transferred to vats having wires suspended from 2-inch iron pipes extending across the top of the vat. The crj'stals of borax form on these wires as well as on the sides and bottom of the vat, those on the wires being sufficiently pure for all trade requirements, while those on the sides and bottom of the vat have to be redissolved and purified by a second crystallization. The pure crystals are crushed, screened, and sorted into three grades — refined cr3'stals, refined screenings, and granulated borax. The crystals and screenings are packed for the market, but the granulated borax before shipment undergoes a final treatment, which consists of heating in an inclined rotating cylindrical furnace, crushing to the fineness of flour in a pulverizer, settling and collecting the dust in a large dust chamber, and packing the final product for market. The Bayonne refinery is well equipped with all modern mechanical devices for the handling and treatment of the crude and finished materials. Table (i. — Drtniled sinnmnrti: 1002.

By fFosKPH Hyde Pratt. The mining' of fluorspar has increased very greatly since the census of 1.S90, due to the large increase in the use of this mineral in metallurgical processes, especially in the iron industrj'. For some years the use of fluorspar for fluxing iron was not large, because it was feared a constant supply could not be obtained. At that time the mineral was produced in only one state, Illinois, although it was l?nown to occur in small (juantity in a number of other states. Now, however, it has been proved to occur in commercial quantity in Arizona, Illinois, Kentucky, and Tennessee. The first census statistics for fluorspar were collected at the Eleventh Census, and these are compared with the statistics for 1902 in the following table: Table 1. — Comparative summari/: 190£ and 1SS9. 1802 , etc.: Number of mines Number of operators Salaried officials, clerks Number Salaries Wage-earuers: Average number . .

" Census figures represent the iiroduct mined. Less than one-tenth of the total quantity and about one-fifth of the entire value reported for 1902 repre- sent the product prepared at the mine for the market, the preparation consisting of drying and grinding, in addition to the usual washing. Of the 22 mines in 1902, li were in Kentuckj-, 6 in Illinois, 2 in Arizona, and 1 in Tennes.see. The prod- uct has increased from 9,500 tons in 1889 to 48,818 tons in 1902, or over fivefold, and the value from $45,835 to $275,682, or over sixfold. In these twelve 3'ears, Illinois, which was the onh' state producing fluorspar commercially in 1889, has increased its pro- duction from 9,500 tons, valued at $45,835, to 18,860 tons, valued at $123,000, or 08.5 per cent in amount and 168.4 per cent in value. One mine in Kentuckj^ was 30223—04 .57 reported idle in 1902.

As shown in Table i, the busiest months in this indus- try, all states combined, were from May to December, inclusive. In Illinois, the largest number was em- ployed in August; in Kentucky the maximum was not reached until October, which was true also of "all other states." The average number of wage-earners, at speci- fied daily rates of pay for the different occupations is shown in Table 4. The majority of the miners received from $1.25 to 11.49 per day, 100 miners, or 56. S per cent of the total number, receiving wages within these limits. For 35 miners, or 19.9 per cent of the total number, the wages were lower, being between $1 and $1.21 per day, while for 41 miners, or 23.3 per cent of the total number, they were higher, 32 miners receiving between 81.50 and $1.74, 5 between $1.75 and $1.99, and 4 between $2 and $2.24. Of the 16 engineers reported in the industrj-, 14 received between $1.50 and $1.74, and 2 received between $2.50 and $2.74. The I'ates paid machinists and engineers were, on the whole, higher than those for other wage-earners. The employees at the higher rates, included under "all other wage-earners," are men who wash or jig the ore.

In the next few years the production increased considerablv, reach- ing 12,400 tons in 1893. Then it fell off to 7,500 tons in 1894 and to 4,000 ton.s in 1.S95, thus reaching the fig- ure at which it stood in the years 1882 to 1884. The vear 1896 marked the beginning of a second period of increasing production, which appears to be still in progress. In 1899 the production was 15,900 tons, which was more than double that of the preceding j^ear. But the most remarkable increase was in the year 1902, when the quantity produced showed a gain of 28,432 tons, or 145.2 per cent over that of the preceding year, and the value of the product, a gain of $158,029, or 138.9 per cent. The average value of fluorspar per ton has varied from $4 to $8. The average was exceptionally high in the years 1896 to 1898, inclusive, reaching $8.21 in 1898. In 1902 it was $5.66; the prices reported for that year varied from $2.86 to $11.50 per ton, this higher value being obtained for the fluorspar mined in Arizona, which was used in California. This increase is due to fluorspar being much more largely used than formerl}' in the fluxing of iron in steel works, and as it is intro- duced into the smelting of copper and the reduction of other metals, there should be a still further increase in its production. The imports of fluorspar are not separately stated in the records of the Bureau of Statistics of the Depart- ment of Commerce and Labor, but are included with minerals and oils not elsewhere specified. The detailed statistics of the fluorspar industrv for 1902 are shown in Table 4. DESCRIPTIVE. Occurrence ivnd use. — Fluorspar is the common name of fluoride of calcium, a mineral occurring in crj'stals and masses of various colors, very commonlv as the gangue of many metallic ores, especially of lead. It is found chiefl}' in veins in limestone, sandstone, mica slate, clay slate, and gneiss. When it occurs in com- mercial (|uantity, it is usually in cleavable masses, and of white, greenish white, or pale green color; but when small openings exist in the veins, the fluorspar is apt to be found in well-developed cubical crystals, which are generally highly colored with various tints of purple, indicating that it is associated with metallic minerals. Until 1S!»8 the only sources of fluorspar in the United States were the mines in Hardin and Pope counties, in southern Illinois, but during that year deposits were opened in Livingston and Crittenden counties, Ky., and in 1900 in Smith, Trou.sdale, and Wilson counties, Tenn.. and in Yuma county, Ariz. As has been shown above, all these states were producers of fluorspar in commer- cial quantity, in 1902. The mineral has been found widely distributed throughout the United States, Init thus far it is only in the four states mentioned that it has been found in suflicient quantity for commercial purposes. In the fluorspar depo.sits of Illinois and Kentucky there is known to be a very large supply of this min- eral, capable of meeting the demand for manv vears. FJAIORSPAR. 891) A.s this overcomes one of the objections often ach'iuiced ag'iiinst using fluorspar in the smelting of iron, nunicly, that a constant supply of tiiis mineral could not lie depended upon, its use ivr this purpose should now int'rease rapidly. Other hindrances to the use of fluoi-- spar for fluxing purposes have been the higher cost of this flux as couii)ared with limestone, inacces.sibility of the deposits, and the action of the slag and gases on the lining of the furnaces. But the recently discovered deposits of Kentucky and Tennessee, together with the deposits in Illinois, furnish an abundant supply, favor- ably located for transportation, either by railroad or water. The use of chromite (chromic iron ore), either in mineral form or as chrome bricks, will make a lining for furnaces which can be afl'ected ))ut little by the use of fluorspar as a flux. Fluorspar possesses qualities that make it especially adapted for the fluxing of ii-on, and these should more than compen.sate for its higher cost, as compared with limestone. Thus far the larger pi'oportion of the fluorspar mined has been used in steel works. Very little is used in blast furnaces or in the smelting of copper or other metals; for these purposes, and also in foundr}- work, its use will un- doubtedly increase rapidly when its value as a flux is more thoroughly understood. Another use of fluorspar, and formerly its chief use, is in the preparation of hydrofluoric acid. At the present time it is estimated that only from .5 to 10 per cent of the product is used for this puryiose. The min- eral is also used in the manufacture of opalescent glass, being considered very essential for this purpose. Tablh -t.—DETAILKI) SUMMARY: 1902. United States. Illinois.

The Census figures of use of gypsum as a fertilizer, Init with the development of the phosf)hate rock industry, wdiich began just prior to the close of the decade ending in isTn. came a corre- sponding reduction in the use of gypsum for land plaster, and in 1880 the total gypsum production, as reported by the United States Geological Survey, was hut 9<>,(H)0 short tons, valued at $100,()00. The iiiiiiiiig of phosphate rock commenced in Soiitli Carolina in lS(i7. and in isTo the prodiu-tioii was (>.">, 211 long tons. In 188(1 the sales of jihosphate rock in tlii' L'nited States amounted to 21L,H77 long tons, \alue(l at $1.123, S23, while the gyjisuiii pi'oduct had fallen, as above noted, to a value of SIiki.oimi. In l.s.sii the sah.'s of phosphate rock were 5oM,i'15 long tons, valued at $2, 937. 776. Florida had hitely liecome a producer. On the other hand, the gi'ouiid gypsum sold as hind plaster in Ls,S',) was hut ln,s,771 short tons, \alued at $233,307, in contrast with the production for l,s70 of ground plaster, valued at $2.6'.ll,S.")l. The shrinkage in the consumption of gypsum for land plaster continues, the growth m the gypsum in- dustry since ls,s',t })eing due to the increasing use of wall or cement plaster. In 1889, 1()S,77L tons, or l:(.i.6 per cent. t)f the gypsum was sold as land plaster: in 1902 onl}' 60,791 tons, or 7.1 per cent. The growth of the industry during the period liSS9 to 19(12 has lieen entirely in the pi'oduction of calcined gypsum. In 188t), ,So,755 tons of gyp.sum, or 32 per cent of the amount (piarried. were calcined, while in 19("i2 the quantity calcined was 671:, 232 tons, or s2.6 per cent of the gypsum quarried, producing 539. 3s7 tons of calcined plaster products — plaster of Paris and wall or cement j^laster. Along with the increased consuinption of calcined plaster there w^as a decrease in the average price from $6.92 per ton in Ls89 to $3.50 per ton in 1902. There wa.s no material change in the average price of crude gj'p.sum, it being $1.13 per ton in 1889 and $1.15 per ton in 19()2. The average value of the land plaster, how^ever, decreased from $2.14 per ton in 1889 to $1.75 per ton in liiO-j. A change in the character of tli(^ industry is also shown ])y the reduction in the numlier of operators. In 187(1, 321 operators were reported, and in 1902 only 15. The numlier of mines, wdiich in l87(i must liave lieen at least 321 -that being the number of opera- tors — was only 62 in l'.i(i2. The production of land plaster requires small capital, the gypsum being simply mined or quarried and ground: and the average values of the product per operator for the years ls5u, 186(.), and 187(.)— $3,061, $3,910, and $8.3S6, respectively — indicates that during that earlier period, wdien land 904 MINKS AND QUARRIES. plaster was the principal or sole product, this industry was small and local in character. The statistics for 19(i2 show a concentration «f the business. The (12 pro- ducing- mines or quarries were controll(>d liy 45 opera- toi's and the averag-e value of the product per operator was $4:»),43(). Of the t)2 active mines or cjuarries, 19 were operated by 2 companies. The reduction in the number of operators and active mines or quarries reflects the growth of the wall plaster industry, which has a wider market and requii'cs a nuich larger capital and plant than the mere manufacture of land plaster. During the period from 1889 to 1902, the value of the product increased 173.1 per cent, the wage-earners 9:-!. 1 per cent, and the amount paid in wages 201.7 per cent. There were 17 idle mines or quarries in 1902. distrib- uted as follows: 8 in New York, 3 in Arizona, and 1 each in Kansas, Missouri. New Mexico, Ohio, Texas, and Virginia. These were owned by 9 individuals, 1 firm, and 5 incorporated companies. Two of the mines in Arizona were owned by 1 individual. Two of the other idle mines, 1 in Kansas and 1 in ^Missouri, were owned by 1 corporation, which operated 1(1 active mines or (juarries in Iowa, Kansas, Michigan, New York, Ohio, and Oklahoma. The statistics of the capitalization of this corporation are included among those of the active mines. The remaining 1 incorporated companies were located 1 each in New York, New Mexico, Ohio, and Texas. Three of these did not report capitaliza- tion. The fourth company reported an authorized capital stock of 25O,(.)00 shares, with a par value of $250,000; all of the common stock, 200,000 shares of a par value of $200,000, had been issued. It reported also authorized bonds of a par value of $25,000, of which $15,0(t(> had been issued, making a total of 1215,000 for stocks and bonds issued. Of the 45 operators in 1902, 13 were individuals, 6 were tiruis, and 26 were incorporated companies. Only 3.ti per cent of the gypsum mined or quarried was pro- duced l)y the 19 individuals and firms, and in Iowa, Kansas, Michigan, Oklahoma, Texas, and Utah the operators were solely incorporated companies.

The outstanding capital stock and bonds issued aggregated $10,670,965. The interest paid on the bonded debt was $2,700; the small amount is explained I)}" the fact that the organiza- tion of several of the companies occurred during 1902, and only 2 companies reported the payment of inter- est on bonds aggregating $-l:.5,0t)0. Dividends amount- ing to |6-t,300 were paid b}- 6 companies, distrii)uted 1 each in Iowa, Kansas, Michigan, Oklahoma, Texas, and Utah. The capitalization of 1 company operating mines or quarries in Iowa, Kansas, Michigan, New York, Ohio, and Oklahoma was credited to Michigan, as its largest production was from that state; and, in like manner, the capitalization of 1 company operating mines or quarries in Oklahoma, Texas, and Wyoming was credited to Texas, whei'e its largest plant was located. Employees and wages. — Of the total amount, 11,059,678, reported as paid for salaries and wages, $759,258, or 71.6 per cent, was paid to the wage-earners, and $300,420, or 28.4 per cent, to the salaried employees. The variation in the number of wage-earners em- ployed at different seasons of the year is shown in Table 6, which gives the average number of men and boys emploj'ed during each month. The employment of boj^s under 16 is reported onlj- in the case of 1 mine. The least average number of wage-earners employed during any month was 773 in Januar}^, and the largest average number for any month was 1,696 in September. For the remaining months the number fluctuated within a comparatively narrow range. The number of wage- earners employed at specified daily rates of pay is also shown in Table 6. The j^revailing rate of pay for wage-earners was from $1.50 to $1.74 per day, 754, or 51.2 per cent, receiving this rate. The per cent receiving less than $1.25 per day was only 2.5; 5.6 per cent received from $1.25 to $1.49 ; 23 per cent, from $1.75 to $1.99; 10.2 per cent, from $2 to $2.24; 3.3 per cent, from $2.25 to $2.49; 2.5 per cent, from $2.50 to $2.74; and 1.7 per cent received $3 and over. Of the total number of wage-earners 614, or 41.7 per cent, were classed as miners or quarrymen. Of these 329, or 22.4 per cent, received from $1.50 to $1.74 per da}^ Nine received from $3 to $3.24 per da jr. Mining and quarrjang on a tonnage basis was reported by 18 mines or quarries, at rates ranging from a minimum of $0.20 per ton to a maximum of $0.66 per ton, with an average of $0,445 per ton. These mines or quarries were distributed as follows: 7 in Iowa, 4 in New York, 2 in Kansas, and 1 each in California, Michigan. Oklahoma, Texas, and Utah. Supplies, materials, and •miscellaneous expenses. — The total amount reported for supplies and materials was $341,760. In the case of operators producing uncalcined gypsum only, either crude gypsum or land plaster, the expense for supplies and materials was small, only 5 or 10 cents per ton. The total amount reported for miscellaneous expenses was $200,769, of which amount $49,912 was paid by 20 mines or (piarries for royalties and rent of mine and mining plant; and $150,857 for rent of offices, taxes, insurance, interest, and other sundries. The mines or quarries reporting the pa3Muentof royalties and rent of mine and mining plant were distributed as follows: Six in New York, 4 in Kansas, 2 each in Iowa, Ohio, Okla- homa, and Wyoming, and 1 each in Texas and Virginia. Mechanical poioer. — Of the 62 mines or quarries operated. 55 reported power, the primary power employed aggregating 7,319 horsepower. Where mills were operated in conjunction with the mine or quarr}^, this includes mill power as well as power directly employed in mining or quarrying. The power was supplied by 68 steam engines, aggregating 6,385 horse- power; 2 gas or gasoline engines with a total of 20 horsepower; and 11 water wheels ha\'ing 914 horse- power. There were, in addition, 5 electric motoi-s with a capacitjf of 68 horsepower. Production. — The total production for the year 19()2 was 816,478 short tons of gypsum quarried, of which 674,232 tons were calcined, producing 539,387 tons of calcined plaster — plaster of Paris and wall or cement plaster — valued at $1,889,190. There were sold in the crude state 81,455 tons of gypsum, valued at $93,914, an average price of $1.15 per ton; and 60,791 tons ground for land plaster, -^'alued at $106,237, an average price of $1.75 per ton. The 539,387 tons of calcined products comprised 188,7(.)2 tons of plaster of Paris, \-alued at $662,928, an average price of $2. 9s per ton; and 350,685 tons of wall or cement plaster, valued at $1,326,262, an average price of $3.78 per ton. The production of the 188,702 tons sold as plaster of Paris consumed 235,878 tons of crude gypsum; and the pro- duction of the 350,685 tons of wall or cement plaster consumed 438,354 tons of gypsum before calcination into plaster of Paris and manufacture into wall or cement plaster. The increase in the marketable gyp- sum products for 1902 over those of 1889 was in quan- tity 434,908 tons, or 63.7 per cent, and in value $1,325,223, or 173.4 per cent. Of the calcined products 65.3 per cent was wall or cement plaster, including all of the calcined product from the states of Nevada, South Dakota, and Utah; 90 per cent and over of that from California, Kansas, Mon- tana, Oklahoma, Texas, and Wyoming; from 80 to 90 per cent of that from Iowa and Oregon; 60 per cent of that from Colorado, and less than 50 per cent only from Michigan, New York, Ohio, and Virginia.

(Jriijiii. — txypsuni deposits ha\'e lieen formed by direct deposition, and by tin; alteration of existiijo- lime deposits. Most of the gypsum deposits of the workl are considered to have been formed by the evaporation and concentration of sea water, although the ealciiuii sulphate is not deposited until about so per cent of the water has l)eeii evapt)rated. Sea water, according to the anal>ses in the Challenger Ileports, contains 3. .5 per cent of mineral matter of the following constituents: I\Tcrnl.

(Typsum deposits, therefore, are more wicbdy spread than stilt, but usutdlj' occur in thinner l)eds. When sulphuric acid, liberated by the decomposition of pyrite, acts on ctilcium carbontite and converts it into calciimi sulphate, there is generally a gracUial transition from the limestone into the gypsum rock. Gj'psuni is deposited by some thermal springs, as in Iceland, where the sulphurous acids on becoming oxi- dized change to sulphuric acid, which comerts the cal- cium carbonate into calcium sulphate, and this when evaporation tak(?s place is deposited in fibrous and crysttilline forms. The theory of Dawson on the origin of gypsum at Plaister Cove, No\'a Scotia, is as follows: p^irst, there was an accumulation of ntimerous thin layers of lime- stone, either so rapidly or at such great depths that organic remains were not included in ;uiy but the ujiper layers. Second, thei'e was an introduction of sulphuric acid, in solution or in vapor, which was a product of volcanic action. Then for ti long time the acid waters acted upon the calcareous mtitcritil without interruption from mechanical detrittis, changing the calcium etirlion- ate to calcium sulphate, and gypsum of go(jd (jtitility acctunulated in consideriit)le thickness. ^Avf/v/vv/r'c. -(jypsum is widely distributed geolog- ically, being f(aind in viirious formations ranging from the Siluriiui up to the Tertiary.

P.sv . — 'T\\i' use of gypsum w;is known at a very early jjeriod, for the Greeks were familiar with it, as shown by the writings of Theophrastus and Pliny. (Tvpsum in its gi-ound, unealcined state is itscd chiefly for kind plaster, a fertilizer. In its calcined form, as plaster of Paris, it has extiMisive and varied uses. Land plaster.- -(.^vov\m\ plaster has long been used as ;i fertilizer, ^'irgil wrote concerning the value of gyp- sum on cultivated lands. Benjamin Franklin called at- tention to the value of gypsum as ii fertilizer for grass by sowing kind plaster in a clover held, so as to form the sentence, ""This litis l)een plastered with gypsum,'' the letters showing by the height and color of the clover where gypsum had been sown. Numerous experiments and tests are on record as to the value of gypsum as a fertilizer. Boussingault in 1841 fertilized a clover field with gypsum and analyzed the clover grown on fertilized and on unfertilized land. These experiments were conducted for two years on the same land, and the analyses of the ash of the clover from a hectare of ground sh(jwed as follows, in kilo- grtims: Anu/i/xi^ iif clonr.^ Aslics I'lx^u Irom CO..

The theories of the action of j^ypsuni as a fertilizer have been many. Sir Humphrj' Davy and others before and after his time have regarded gypsum as a direct source of plant food. It is now thought that gypsum acts as a fertilizer in three wavs, one mechanical and two chemical: (1) The gypsum bj' mechanical action flocculates loose soils. (2) Gypsum as pointed out by Storer' has nearl3^oue- half its weight in oxygen and gives this up to many substances, and so may act upon nitrogenous and car- boniferous substances in the soil. (3) Gypsum decomposes the doul)le silicates in the earth, setting free potash as a soluble silicate. Accord- ing to Storer, the action is as follows: >XSiO„-CaOSO,= XsiO., +K2OSO3 By this means the potash in solution reaches the roots of the plants. Soils with abundant potash do not need land plaster, and soils with no potash compounds are not benefited in this respect by it. Planter <>f Par Ik. — The phenomena attendant upon the baking and hardening of plaster of Paris were first studied hy Lavoisier. In the Comptes Rendus of Feb- ruary 17, 1765, appears the following: "After having removed the water of hydration from gypsum i)y h(>at, if it be presented to it again (this is conmionly known as the mixing or tempering of plaster), it takes it back with avidity, and suddenly assumes a state of irregular crj-stallization; the small t-rystals which form become confused with each other, the result being a ver3' hard mass." Lavoisier discovered that when plaster was baked at too high a temperature it lost its peculiar property of setting, and that when it was heated the water of crystallization was removed at two different stages, three-fourths of it being mucli more easily renioved than the remainder. Payen, in 1S8(), found that gj'psum began to lose its water of crystallization at 11.5" C, and that the loss increased rapidly as the temperature rose. He concluded that a temperature of from 110'^ to 120'-' C. was the best for calcination, hut that plaster of Paris could >)e made at a lower tempera- ture, even as low as 80" C, if the burning were t'on- tinued long enough. He found that gypsum was dehydrated if heated to about '250- C.,and fi'om 30()- to 400'-' C. it lost completely the properties of hydi-ation. Le Chatelier experimented in 1887 on the etl'ects of temperature on gj'psum. On heating gvpsum to 200'-' C, he found that there was a constant rise in tempera- ture, with two ))reaks; the hrst halt at 128 C and the second at 1(>-!'" C, indicating the existence of two dif- ferent hydrates, whose decomposition took place at the temperatures stated. The dehydration was found to be incomplete at 155- C. and complete at 194'- C. An analj'sis of the first hydrate gave: Per cent. Water 6.7 Calriuni sulphate 93. .3 100.0 This agrees very closely with the formula (CaSOJj H,,0, which gives: Pur cent. Water 6.2 Calcium sulphate 93. 8 100.0 Gypsum has 1 part of calcium sulphate united with 2 parts of water, while this hydrate shows 2 parts of cal- cium sulphate united with 1 part of water. The same hj^drate is found in the incrustation of the boilers of ocean steamers when fed with sea water, as shown b}^ the following analysis: AiKilijsig iifhniliT iiiiritsliitioii ffdin a triniK-Atlmilic steamer.

The temperature at which this compound is com- pletely dehydrated lies between 1H((- and 170- C. Broken up and mixed with water, it hydrates and hardens. Further experiments showed plaster of Paris to l)e :i definite hydrate with the formula (CaSOj).,H„0. The second halt noticed in Le Chatelier's experiments took place tit 163- C, and from this temp(>rature to 221 C. no change was noted in the plaster, but beyond 221 C. the plaster, when mixed with water, did not ab- sorb it readily and set only after a long time. If the heat reaches 343=' C, the plaster acts like an tmhydrite and is said to be "dead burned." It will not set on the addition of water. When heated still more the sub- stance melts and, on cooling, forms a crystalline mass, which can not he decomposed by heat, except i)\ the presence of organic matter, when it changes into CaS. If this suljstance is acted upon by car))on dioxide gas (CO.,) and water, sulphureted hydrogen gas is formed. The burning of gypsum is, therefore, a very impor- tant Diatter, and calciners become very expert. If the gypsum is underburned, the new hydrate is not formed, and the plaster will not set. If it is overburned, the plaster sets very slowly. Lavoisier gave the following account of his theory of set in plaster: I took the calcined plaster, which hardens readily with -\vater, and threw it into a considerable amount of water. l-:ach molecule of plaster, in passing through the licjuid, seized its molecule of water of crystallization and fell to the bottom in the form of small brilliant needles, visible only with a strong lens. These needles, dried in the open air or with the aid of a moderate heat, are very GYPSUM. 909 soft and silky to the touch. Under a microscope it is perceived that what was taken under the lens for needles are also parallel- opipeds, very fine, some thicker, many thinner, and many more elongated. The plaster in this state is not capable of unitinj; with water, but if it is calcined anew these small crystals lose their transparency and their water of crystallization and become again a true plaster, as perfect as before. One may, in this fashion, success- fully calcine and recrystallize the plaster, even to infinity, and con- sequently give to it at will the property of seizing water. Landrin, who, in a paper published in 1874/ quoted the above, and gave the re.sults of a study of plaster, divided the set of plaster into four periods as follows: (1) The calcined plaster, on contact with water, unites with this liquid and takes a cr3'stalline form. (2) The plaster dissolves partially in the water, which becomes saturated with this salt. (3) A part of this liquid evapoi-ates, due to the heat set free in the chemical combination. A cr^'stal is formed and determines the crystallization of the entire mass, a phenomenon which is analogous to that which takes place when a piece of sodium sulphate is placed in a saturated solution of this salt. (4) The maximum hardness is reached when the plas- ter loses enough water to correspond exactly to the formula (CaSOJ.jHgO, this maximum lieing to the remainder in proportion to the quantity of water added to the plaster to transform it into mortar. The maximum hardness then was reached when the plaster contained about 20 per cent of water. Landrin believed that the loss of water was due to the evaporation. Le Chatelier showed that plaster would set in a vacuum, so that evaporation was not a necessary step. According to Le Chatelier, the plaster of Paris dis- solves, becomes hydrated, and then crj'stallizes out as gypsum, and every particle of the plaster goes through these steps. Microscopic examination" shows that ground gypsum, before calcination, is composed of rather large masses of various sizes, these masses con.sisting of more or less broken crystals. After calcination these larger masses are broken up into fine granules nearly uniform in size and shape. As the material is heated, the water is changed into steam and, expanding, breaks the crys- tals into finer particles. There is thus a physical change, as well as a chemical one. When water is added to the calcined plaster, small needle-like crystals are seen forming and shooting out here and there, and these, as they become more almn- dant, unite and form a solid mass, in which the indi- vidual crystals can scarcely be distinguished. Open spaces left in the mass are finally closed and a firm solid mass results. Uncalcined gypsum treated with water shows, under the microscope, very little change. Gypsum crystal- 'Annales de Chimie, 1874.

Crystallization is aided by the small size of the grains, and the finer-grained plasters set more rapidly than the coarser-grained ones, as shown l)y the comparison of the fine dental plasters with ordinary plaster of Paris. Mativfiicture. — In the manufacture of plaster of Paris the gypsum rock is crushed and ground into flour in a buhr mill, a roller mill, or a disintegrator. The ground gypsum is then passed into storage bins. In some mills the flour gypsum is conveyed to the bins by an air blast. The calcining kettles are made of boiler steel and hold about 8 tons; the flame is carried around the sides, by flues, so as to heat all parts. In charging, the ground gypsum is run slowly into the kettle, which is kept at a temperature of 212° F. or over; about an hour and a half is consumed in filling to a depth of 5 feet. The material is kept in motion by a mechanical stirrer, it being of the greatest importance that the partly calcined plaster shall not remain in contact with the heated iron. The slow filling tends to keep the heat constant or nearly so during the charging, and as the boiling increases the plaster is occasionally thrown in "waves" out of the kettle. The heated material l:>oils like thick cream, and runs almost like water. The lioiling is, of course, due to the escape of the water of crystallization and the hygroscopic water that may be present. The boiling takes about three hours; a short time before completion, when the tem- perature reaches 270- F., there is a sudden settling down and the steam ceases to rise, marking the period of formation of the first hj^drate. Soon the mass begins to boil again; after a certain time, quite accu- rately determined by the expert calciner, when a tem- perature of approximatelj' 350- F. is reached, the charge is done, the discharge gate is opened, and the finished product runs out into a vault. The refilling of the kettle for the succeeding charge begins at once. Hidarders. — As plaster of Paris, when mixed with water, sets in from six to ten minutes, material is incor- porated therewith, either during its manufacture or at the time of its preparation for use, to delaj' or hold back the set, in order that the cement plaster can be prepared in quantity and applied with uniform results. These compounds or admixtures are known as retarders or restrainers. In the early days of cement plaster, glue was added by the workman when he prepared the material for use; but now. to secure uniform results, the retardor is, as a rule, incorporated with the plaster in the process of manufacture. Citric acid was used for a time, liut this was expensive, and the results were often uneven. As magnesian limes set more slowly than calcareous limes, it was thought that the addition of magnesian limestone would serve as a retarder, but the use of this substance is said not to be a success. 910 MINES AND t^UARRIKS. Ill the days of the Romans, hlood was used to retard the set of plaster of Paris, and organic matter from slaughterhouse refuse (tankage, bones, hair, etc.), forms the base of many of the retarders now in use. Any substance which, when added to the water with which calcined gypsum is mixed, or to the dry plaster, will keep the molecules apart or from too close con- tact will delay the crystallization and retard the set- ting. Such substances are dirt or organic matter not of a crystalline character. Insoluble material or car- bonates of the alkaline earths will dilute the plaster so that it will not set as quickly as the unadulterated plas- ter. Whether a retarder weakens the cement plaster or not is a disputed question among architects and plasterers, although it is conceded that the addition of too much foreign material reduces the strength of the mass of interlacing crystals. As a general rule the prolongation of the period of crystallization or set is determined by the quantity of retarder added to or incorporated with the plaster. Calcined plaster which sets slowlj', whether retarded or not, is known as cement plaster. AcceJerators. — It is a well-known fact that when a salt crj^stal is dropped into a supersaturated solution of a salt, as for instance sodium sulphate, the whole mass immediately crystallizes. Crystals, or (>ven solid par- ticles of foreign material, will hasten the crystalliza- tion. Hence, to make a quick-setting plaster, as for dental use, some other crystallizing salt, as alum or borax, is added, in small quantity', to the calcined gyp- sum. The result is that, after solution, the addeil salt has a tendency to crystallize, and thus starts the process in the dehj'drated gypsum. I'ren employed as a bath in whidi plaster casts are immersed.

A large munber of patents have been issued for re- tarding compounds and admixtures, and for prepared plasters, as well as for processes of manufacture and for hardening gypsum, and a digest of the same will be found in tin appendix. There have also lieen issued some iiSo or more patents for improvements in the arts involving the use of gypsum or plaster of Paris in the manufacture of artificial stone, wall and roofing cements, pa\-ements, crayons, blackboards, heat insu- lating composition, etc. GYPSUM.

The detailed statistics of the industry for 1902 are given in Table 6. DESCRIPTIVE. The name phosphate is applied to the salts of phos- phoric acid, chiefly "orthophosphoric" acid, which is a tribasic acid (H3PO4) and from which a great variety of salts are obtained. Each of the three hydrogen atoms in the acid can be replaced by a monad element, forming, consequently, three varieties of salts, namely, those in, which one h3'drogen atom is replaced, those in which two hj'drogen atoms are replaced, and those in which all of the hj'drogen atoms are replaced. .Salts in which all of the hydrogen atoms have been replaced are called ortho or neutral phosphates, while those still containing one or two atoms of hydrogen are called acid phosphates. Calcium pho.sphate, or, more strictly speaking, tricalcium orthophosphate. is the most im- portant of the mineral phosphates and this class forms the large mineral deposits utilized for the manufacture of fertilizers. Historical. — According to historical records, the Romans utilized the excrement of birds for fertilizing the soil, and in the twelfth centuiy the Arabs and Peruvians used the guanos of their respective countries for a like purpose. The waste clippings of bone and ivory from the but- ton and knife factories of Sheffield, England, green.sand from the counties of Kent and Essex, England, marls from the state of New Jersey, and boneblack (.spent animal charcoal) and crushed bones were used as fer- tilizers at different times during the eighteenth and nineteenth centuries, but while the beneficial results from their use were recognized and appreciated, the real cause of the stimulating effect seems not to have Ijeen definitely recognized until Dr. Justus von Liebig, of Geissen, Germany, evolved the idea that sulphuric acid should be added to bone fertilizers in order to render soluble the phosphate they contained. It was not until the year 1813 that the Duke of Richmond, after an exhaustive series of experiments upon the soil with both fresh and degelatinized bones, came to the con- clusion that their value for fertilizing purposes was due to the large quantity- of phosphoric acid contained in them. To prove this effect a number of vegetables were planted in burnt sand rich in eveiy element of fer- tility except phosphoric acid; no development of the plant took place until calcium phosphate had been added to the sand, but after this addition the growth became ffourishing.' The calcium pho.sphate in bones had hitherto been considered as useless owing to its insolubility, and the fertilizing element was considered to be the gelatinous matter. Shortly after 1810 Mr. J. B. Lawes put Doctor von Liebig's ideas into practice, and began to manufacture artificial fertilizers at Deptford (London), England, by mixing sulphuric acid with crushed bones. In the year 1815 Professor Henslow recommended that the Cam- bridge coprolites, rich in calcium pho.sphate, should be used as a substitute for bones in making fertilizers, and, acting on this suggestion, the numerous bone crushing works were quickly converted into chemical fertilizer and superphosphate factories. The coprolites of Cam- bridge were supplemented bj' the phosphate deposits in Suffolk and Bedfordshire, but it was not until twenty- five 3'ears later that the phosphate mining industiy began to assume a commercial importance. This slow growth is attributed to the immense supply of guano obtained from Peru, the best beds of which did not become exhausted until between 1870 and 1875; the failure of this source of supply immediately led to the sul.)stitution of other material for the manufacture of fertilizers. ly. In 18^0 the is- lands of Curasao and Oruba, in the Dutch West Indies, supplemented the output of high-grade phosphates and shipped an average of lo,n(io tons for the year. In the decade ls8(» to 189() the sources of the supply of phosphate rock altered very consideraljly. At the end of this period Spain, which in 1882 and 1883 shipped 100,000 tons to the United Kingdf)m, practi- calh' ceased to export. In France the old sources of supply had been replaced to a large extent })y the newer fields in the Somnie and othei- departments in the north. Belgiiun had assumed an important place, producing about 150,000 tons of phosphate from the mines at Mons alone. In the Uniterl States the South Carolina deposits had been developed to a A'ery large extentand Florida had begun to contribute appi'eciably to the supply. CIiaracti^rixtlfK itiul use. — ^I'he vai'ious depcjsits of phosphatic material have not yet been classified geolog- icalh' owing to the dithculty in determining the position of several of the deposits, augmented by the large num- bei' of fornjs which the phosphate assumes and the com- plex blending of cin'tain \'arieties. The counuon tech- nical classification makes the broad distinction between mineral phosphates, whose origin can not be traced to animal life, and rock phosphates, more or less mineral- ized, but dii-ectly traceable to an organic origin. On this basis the onlj' mineral phosphates are those con- taining crystalline apatite, which occur in Canada, Nor- way, and a few localities in Spain. The deposits at Nassau in Germany, Lot-et-Garonne, Tarn-et-Garonne, andA\e3'ron in France, and Logrosan and Caceres in Spain are usually included in the mineral phosphates under the arbitrary and indefinite term "phosphates." The term rock phosphates includes the remaining varieties of phosphatic limestone, coprolites, nodular phosphates, concretionary phosphates, arenaceous phos- phates, sheet-rock phosphates, and bone beds. The value of phosphate rock in the United States lies solely in its use as a fertilizer to enrich land im- poverished by continual removal of crops that have grown thereon, or land which did not originally possess the components necessary for the normal growth and development of plant life. It has been only within comparatively recent years that the relation Ijetween plants and soils has been sci- entitically studied. In general the manner of life in plants resembles that of animals or man, in that they require certain foods in stated proportions which are digested or assimilated, they must breathe a certain atmosphere, and they are subject to the influence of heat and cold, light and darkness. The tissues of plants, like those of animals, are composed of carbon, hydro- gen, oxygen, nitrogen, and certain mineral acids or : bases, notably phosplioric and sulphuric acids, lime, ' magnesia, iron, and potash; and the growth of a plant ])ears a cU)se relation to that of an animal for the reason that it constantly al)sorbs elements from the soil and air to build up its structure. The relation of plant life to animal lift> is reciprocal. Animals breathe in the oxygen of the air and convert a small part of it into carl)on dioxide, which is exhaled and returned to the air, while plants, under the action of chlorophyl and sunlig-ht, absorl) carljon dioxide from the air and decom- pose it into carbon and oxygen, utilizing the former to build up the t-ellular structure and returning the oxygen to the air. The chief elements assimilated by plants, and consequently removed from the soil when the plants ai'e cut down and taken away, are nitrogen, phosphoric acid, and potash. These compounds play a very im- portant part in the functions of vegetation and are the most liable to be exhausted from the soil. The estimated mean annual ([uantity luid value of a few of the impor- tant vegetable products in the United States have been compiled as follows: ' ' rhofjpliateM iif America, \yA\if' 14.

According- to Wyatt, the total weight of the ii.sli con- tained in the entire annual cereal production of the United States (wheat, maize, oat.s, barley, rye, and luick- wheat), about the year 1890, exceeded 17,500,000,000 pounds, containing 2,714,585,473 pounds of phosphoric acid/ Of course, a large part of the phosphate content of the plants was returned to the soil in one form or another, but the annual loss to the soil was nearly 1,500,000 pounds of pho.^phoric acid. As the area of cereal production at that time A\'as 110,378,857 acres, these figures show that the quantitjr of phosphoric acid removed annually by the cereal crop is approximately lt> pounds per acre. Similarly, the quantit}' removed by the hay crop is calculated to be 12.5 pounds per acre. Further, it has been shown that every cow kept on pasture land carries off during a sunmier not less than 5() pounds of calcium phosphate in the shape of veal, butter, and cheese." These few instances show in a striking manner the enormous loss of phosphoric acid occurring in agricul- tural districts, and the necessity of returning to the soil those salts which have lieen removed therefrom.

The phosphate deposits of the United States are described by states as follows: Florida. — Phosphate rock occurs over a large area, extending from Lake Okeechobee on the south to the extreme northern part of the state — a distance of 210 miles, and averaging 30 miles in width. The deposits of commercial value, however, are comparatively few in number and are widely scattered throughout the region. The three chief classes of the phosphate rock product in the order of importance are hard rock, land pebble, and river pebble. Hard rock is mined in an area of 90 by Id miles, extending from Albion on the north to Bay City on the south. The material is obtained from pockets which ' Phosphates of America, pagf 15. HTnited States Geological Survey, Bulletin 46, " Xaturc and Ori- gin of Deposits of Pliosphate of Lime," b}- R. A. F. Penrijse, .Jr. vary in yield from a few tons to many thousands, and run so irregularly that it is fre(.iuently neces.sary to change the location of the mining plants. In former times the mining operations were limited soleh' to the bowlders of phosphate rock, which varied in weight from a few pounds to many tons. The mining con- sisted in removing tlie rock from the pits, drying it in the kihis, and shipping it without any additional prep- aration. Littler capital was called for, and many hard- rock companies were formed to mine the rock, but thej^ finally withdrew f i-om business on account of the scar- citj' of deposits easy <.>i extraction. Attention was then directed to mining the gravel pho.sphate, which repre- sents the .smaller or broken pieces of the bowlders that occur intermixed with claj', Hint, etc., the sterile mate- rial being removed by washing in the ordinary log washer. Later, as the mining and milling pi'ocesses became more complicated and costly, large central plants were erected for cheaper treatment cost, but the economies sought, however, were not realized, on account of the small size of the individual deposits and the consequent expense of tran.sporting the crude material containing less than 15 per cent tricalcic phos- phate from the mines to the mill. At the present time the cheapest method of treatment is to have one or more removable washing plants, each of a capacity of from 10 to 50 tons of clean rock in twelve hours. These plants are so constructed that they can easily be taken down and removed to new localities. It is also the present practice to crush, wash, and screen the entire product of the mine. The most recent practice in mining hard rock is the installation of dredges of the tlipper type to mine deposits that have been worked down to the water level, particularly in those cases where it has been found inipractical)le to handle the water with pumps. The use of the dipper dredge is economical, and with deposits that can Ije handled 1:)y this method A-erv excel- lent results have been obtained, so much so that deposits unworkable at a profit by the older methods of mining are now treated with commercial success, the clav, sand, and fine material being removed in loe wa,shers plentifully supplied with water. The washed rock is carefully hand picked on a picker belt, dried in kilns, which consume from 5 to 7 cords of wood per 100 tons of rock, and is then ready for shipment to market. The average cost of production, f. o. b. at the mines during 1900 was from !?3.50 to $1 per ton. According to C. G. Memminger those deposits most favorable for cheap transportation and mining are almost exhausted, and the present etticient methods of mining and handling- leave but little room for diminishing the cost, conse- quently with the gradiuil exliausticm of the best 924 MINES AND QUARRIES. deposits the cost of production must increase. It is cpiite probable tliat tlie cost of production of from $3.50 to $4, f . o. b. at the mines, is as low as it ever will be. The cost to the consumer, however, is regulated largely by the cost of transportation from mines to port of shipment. Hard rock is sold on a guarantee of a miniumm of 77 per cent tricalcic phosphate (bono phosphati". of lime) and a maximum of 3 per cent iron and aluminum oxides. Practicallj' the entire output is exported, chiefly to Germany. The ports for shipment of hard rock are Fernandina, Port Inglis, and Tampa, Fla., and Bruns- wick and Savannah, Georgia. The land pebble phosphate rock occurs in Polk, De Soto, and Hillsboro counties, Florida, occupying an area of about 2,()00 scjuare miles, beginning a few miles north of Bartow and extending over the upper i:)ortion of the drainao'e basin of the Peace and Alaha rivers. Duringf to o the past few yeai'S the entire product has been obtained from Polk county. The area of the occurrence of land pebble is restricted and the deposits wideh' scattered, rendering this branch of the industry of comparatively less importance than the others, yet several hundred thousand tons of phosphate may be obtained from a single deposit. The pebbles are roughly rounded, of a gray or brownish color, and \ary in size up to two inches in diameter. In preparing the material for the market two classes of product are made, the size of the coarser being from one-sixteenth to 1 inch in diameter. The deposits are usually along the stream courses, in low swamps, or in bay heads. The thickness of the deposits varies from a few inches to Is feet, a^-eraging 10 feet for the district. The peljble, which usually represents less than 25 per cent of the mass, occurs in an argilla- ceous uiatrix, sometimes Acry sticky and tenacious, and sometimes sandy and readily disintegrated; the over- burden consists of sandy soil, clay, and a so-called con- glomerate rock of varying character in difi'erent parts of the deposit. The bed rock varies from a hard yellow marl to a soft, clay-like material. The highest grade of land pebble contains from (iS to 73 per cent of tri- calcic phosphate and from 3 to 4- per cent of iron and aluminum oxides; the low-grade material has from tlo to 65 per cent of tricalcic phosphate and from 4 to 5 per cent of iron and aluminum oxides. At the present time land pe))ble is sold on a guarantee of a nunimum of 68 per cent of tricalcic phosphate and a maxinuuu ot 4 per cent of iron and aluminum oxides; conditions which, in ordei' to operate at a profit, call for an a^'erage yield of 2o per cent of peblde to the mass, an average mininuun thickness of s feet of the deposit (yi(dding 3,733 tons to the aci'c), and an overVmrden not exceeding the thickness of the deposit. AA'ithin i-ecent years a hydraulic method of treating land pebble has been de\-isi'd, which is undou))tecl]\' the only practical method of handling this clasM of matci'iah The impoiiant feature of llic ]ir-ocess is tliat the water which is used to break down the rock also partiallj' dis- integrates the matrix and renders the succeeding wash- ing foi' the separation of the pebble a very simple operation. According to C. G. Memminger the equip- ment of aliydraulic plant consists of a steam shovel for removing the bverT)urden, one or more dredges fitted with l)oilers of from 400 to 500 horsepower, a Kbinch centrifugal pumi>, hydraulic-pressure pumps, screens and washers, and barges to carry the pebble to the mill. The mill should contain a sufficient immber of washers, rotary driers, elevators, boilers, and drv-storage bins of from 4,000 to 15,o0() tons capacity — an equipment which calls for a'heavv investment. .V plant with one dredge and two driers should produce 5n,()(K.) tons of pebble per year. The method of mining is lirietl}' outlined as follows: The over})urden lun-ing been removed by the steam shovel, the dredge is launched in a suitable excava- tion and the suction pipe from the centrifugal pump on the dredge is laid some 150 feet in advance, where a small sump hole is opened for suction. Streams of water from two hydi'aulic giants, working luider a pres- sure of from 1(H_) to 11<> pounds per square inch, are directed into the hole, which is increased to a consider- al)le size in a short time. The suction gradually be- comes lowered until thi' sump is formed in the bed rock. As soon as possible the giants are placed in the pit. and as the banks are cut down the material passes with the water to the sump and is punqjed to the dredge, where it is screened, the peljble being thoroughly washed and separated and the debris discharged at the side of the dredge. As the pit becomes enlarged it is a good prac- tice to use a second centrifugal punqi in connection with the pimqj on the tlredge. In tliis way a pit of several acres in extent can be mined. The pump and pipes are removed from the i)it as soon as economy in pit size is reached. The pit is filled with water and the l)ank between the dredge and the pit is broken. The dredge is then moved on and operations Ix'gin afresh. The pits form a chaiuiel for the transportation of the pebble in barges. On reaching the mill the pel)ble is elevated, thoroughly washed, dried, and stored for shipment. The most modern plant in this district has been equipped with electric motive power, the intention being to eliminate the dredge by using a series of electrically-driven centrifugal pumps which will foi'ce the entire material mined to the mill, a central piuiip- ing station giving the hydraulic pressure required. Under certain conditions this system promises excellent results. An innovation at the works of one of the phosphate companies is the installation of a centi'al plant to gener- ate electric and hydraulic power for the mining opera- tions. Th(; residts have proven eminenth' successful and under proper conditions th(^ method promises to sujiersede the old(>r and less economical ones. The liigliest grade de])osits with light overburden PHOSPHATE ROCK. 925 and greatest yield per acre are fast being exiiausted, and fuel, which is a large item of cost, is rapidly lieing exhausted in the vicinity of the mines. The question of fuel supph' is one of great importance in connection with the future of the industry. Large tracts of wood- land have been bought up by the various companies, but wood will undoul)tedly l>e supplemented by coal when the mines control the transportation to the point of shipment. Fuel oil also will become a possible sub- stitute for wood under the new conditions of transpor- tation. The present cost of production, f. o. b. at the mines, is from $]..50 to $2 per ton, a figure that will doul)tless increase very materially in the near future. The prod- uct is shipped from Port Tampa. At the present rate of production the deposits containing (38 per cent and upward of tricalcic phosphate, and low in iron and aluminum oxides, will be exhausted within a few years. Those containing from tii to 67 per cent tricalcic phos- phate and from 4 to 6 per cent iron and aluminum oxides are in very large reserves. There has been a marked tendency toward more careful methods in the preparation of the rock for the market, which is attained usuallv by installing one or more log washers in addi- tion to the ordinary doulde log washer plant; and bj' , crushing the rock after it has been dried, and sub- sec|uently screening it, this procedure has been \)vo- ductive of good results with certain classes of rock. As the higher grade deposits become exhausted the methods of treatment must lie improved in order to handle the lower grade rock at a lessened cost. As a proof of the growing scarcity of the best class of rock, deposits having an overl)urden of from 25 to .30 feet are now being opened up and developed. Deposits of this character a shoi't time ago were declared unsuited for profitable working. The excessively high transportation and terminal charges prevailing in recent years have forced miners to seek relief. One company has constructed a private railroad from the central plant at Rockwell to Port Inglis, IS miles distant, at the mouth of the Withla- coochee river. The port is an open roadstead, and the vessels have to be loaded by lighters. As in the case of the hard-rock miners, there have been several unsuccessfid efforts to consolidate the large miners of land pebble into a community of interests, which would eliminate useless competition and enable the producers to maintain prices at a levs not operate at depths greater than from 20 to 25 feet. Occasionally, for depths greater than 20 feet and up to 50 and 00 feet, a clam-shell bucket dredge is used, consist- ing of a contrivance of 4 or 6 iron claws which open as they are lowered and close forming a bucket as they ascend. The bucket, generall}' of about 1 cubic yard capacity, is operated from a swinging crane covering a radius 'of 25 feet in front of the scow; the material is delivered at a height of 14 feet above the deck into the receiving hoppers which feed into the washers. The cost of operating a claui-shell bucket dredge is from four to five times that of the ladder bucket dredge. Both the rock and nodules from the river and land deposits occur in verj' irregular masses or fjlocks of extremely hard conglomerate of variegated colors, which weigh from half an ounce up to more than a ton. The mean specific gravity of the material is 2.4, and the rock is perforated with a network of very small holes, the work of iniuunerable Crustacea, now filled with sands and clays from the overlying strata. Some- times the nodules are quite smooth or even glazed as if worn ])y water; in other cases they are rough or jagged. The average anah'sis of South Carolina rock may be taken as follows: Per cent. 59.63 - S. 68 0. 73 6. 60 Tricaluic phasphate Ca3(P0,)„ Calciuiu carTionate CaCOj Magnesium carl)onate ^MgCOs Iron and aluminum nxiiles Fe^Os and Alj'-'a Sulphuric acid HvSOj -i Calcium fluoride CaF, J Water and loss on ignition H,0 Silica anil undetermined Si("l„ ■i. SO s. 00 n . .=S6 The land rock occurs chiefly in the vicinity of Charleston, while the river rock is eontined to the Coo.saw river and other streams in the vicinity of Beau- fort. The land rock contains from 57 to 60 per cent fif tricaleic phosphate, but has also a higher percentao-e of iron and aliunina than the river rock. That portion of the river rock which is low in iron and alumina is mainly shipped abroad. The excellent quality of the South Carolina product, togetlier with the favorable shipping conditions, place the production on a permanent basis, and the supply of reserve rock known at the beginTiing of the present decade is calcidated to furnish a supply at present rate of consumption for thirty-five years to come. In recent years there has been a slight decrease in the annual production of river rock. The methods of mining and preparation have not changed materially during the past decade except that steam shovels are replacing hand labor for the removal of the overl>urden and the mining of the land rock. With regard to land rock, Francis AVyatt describes the method of treating it in order to make it marketable as follows: (1) mining or excavating, (2) washing to remove sand and other ster- ile impurities, and (?,) drying in kilns to drive off the contained moisture. PHOSPHATE ROCK. 927 Taking these in their order, it its custoinary to estab- lish a trunk railroad, starting at the ri\er front or on the bank of some convenient stream, and passing through the center of the property to be exploited. Alternate laterals can be run off at right angles from anj' portion of this main line, at a distance of say .500 feet, in conformity with the nature of the groiuid. Be- tween and parallel to these laterals a ditch or drain is dug to a depth extending from 4 to 5 feet below the phosphate strata. From this main drain th(^ exca\'ators start their lines at right angles to the laterals, commenc- ing at one end of the Held and digging trenches 1.5 feet wide and 5o0 feet long, the work being so arranged that the men are stationed at inter^-als of 6 feet. Every man is supposed to dig out, dailj', a pit 6 feet long, 1.5 feet wide, and down to the phosphate rock. The over- lying material is thrown out to the left-hand side of the trench. The phosphate itself is thrown out to the right and taken in wheelbarrows to the railroad cars which pass at either end of the trench. The water drains from the trenches into the underlying ditch, and is thence pumped out by means of a steam pump worked by a locomotive engine. The pump and the engine are secured to connected railway platforms, and run along the railroad track from one ditch to another as occasion requires. The cars loaded with the crude phosphatic material dug out of the pits are run down to the washing appa- ratus, which is constructed at an elevation of 30 feet from the ground, and generally consists of a series of semi- circular troughs from 20 to 30 feet long set in an iron framework at an incline of about 2(.t-inch rise in their length. Through ever}' trough passes an octagonal iron -cased shaft ])rovided with blades so arranged and distributed as to form a screw with a twist of 1 foot in 6, which forces the washed material upward and pro- jects the fragments against each other. The phosphate- laden cars are hauled up an incline and their contents dumped into the bottom trough, where the phosphate encounters one or more heavy streams of water, pumped up by a steam pump. This water does not run oil' at the bottom, but overflows at the higher end near where it enters. AVhen sufficiently washed the mate- rial is pushed out upon a half-inch mesh screen, the small debris being received on oscillating wire tables below. 1 The phosphate is now ready for kilning or drying, and of all the methods hitherto adopted for this im- : portant process, that of simple roasting in an ordinary kiln, such as is generally used in the manjifacture of bricks, is said to have been foimd at once the most rapid, effective, and economical. The lock pile is built on layers of pine wood, and owing to its content of a considerable quantity of organic matter it readily lends itself to combustion and requires but a short time to become quite red hot. The kilns are made suiBciently large and are so arranged as to allo^v free passage to a train of cars, which, running on the main line of rail- road, can be loaded in the kiln, run down to the landing place, and discharged directly into the })arges or boats on the river. The total ijroduction of phosphate I'ock in South Car- olina, based on marketed output, from ISflT to and in- cluding 11)02, as i-eported I13' the United States Geolog- ical Survey, is: Land rock, t),7o2,139 long tons; river rock, 3,930,3ti2 long tons; total, 10,(;32,.5ol long t(jns. Te/mt'f per cent of these components, respectively. The hard rock is compact, heavy, oolitic in structure, yellow white in color, and occurs like the l)lue rock in a well-detined stratum of about two feet in thickness. It is of high grade, Ijut occui's in small (juantities. The Mt. Pleasant rock contains no pyrites, l»ut little tluorite and usually a high content of tricalcic phosphate. Washing is necessary in order to remove the iron and alununum oxides present in the crude rock as it comes froiri the mines. The mining at Mt. Pleasant is all open-cutworlv. From 8 to 9 feet of o\'erl)urden is re- moved by hand or with scrapers and the rock removed with pick and bar. no explosive being necessary'. Usu- ally the mined rxjck is dried, under sheds on a cribwork of cord wood, wluch is tired, yielding a thoroughly dry pi'oduct. 1'he di-y rock is then crushed, screened, and storeil oi' shi];[)ed. The high grade material is obtained chietiy from Mt. Pleasant and vicinity, while lower grade (le])osits exist in Hickman, Giles, and Sumner counties. For the former class of rock there I is a good export market, but the low grade rock is consumed mostly at home. The w^hite rock deposits are in Perry county, the largest development ])eing at Toms creek; it is far from the railroads, but is within 4 miles of the Tennes- see river, which ali'ords water transportation. The rock closely resembles Florida land rock in appearance iind occurs with chert in pockets of variable size. Selected samples show a high content of tricalcic phos- i phate and low iron and aluminum oxides. On account of its unfavorable location but little work has been done on this property. White rock is found in other localities in Tennessee, but so far the deposits are of little, if any, importance. Oflii-r stafev. — The geological survey of Alabama has exannned several well-defined deposits, the chief one being the Ilamlnirg bed in Perry county, which is part of a formation extending nearly across the state, although at only one or two points is the material of sufficient richness to make it of importance. The Coatopa bed in Sumter county has been traced for some distance. The Snow Hill bed in Wilcox and Marengo couijties carries a higher percentage of tricalcic phosphate than either of the other deposits and holds out more promise of commercial value than ixny other in the state. There has been no production of phosphate rock in Alabama since 19(K), in which year 334 long tons, valued at ^534, were produced. In Arkansas phosphate rock has been found in the counties of Independence, Stone, Izard, Baxter, Marion, Searcy, and Newton, in the northern part of the state, but little prospecting has been done, owing to the dis- tance of the deposits from the railroads. The majoritv of the samples analyzed prior to 19("»2 showed a low content of tricalcic phosphate and were high in iron and aluminum oxides. In 1902 a large fertilizer plant was built near Batesvillc. on the White River Railroad, which was being extended to the mines. Mining opera- tions have been liegun in a layer of phosphate rock t'ontaining from fiO to8(» per cent of tricalcic phosphate and less than 3 per cent of iron and aluminum oxides. The deposits promise to be of consider!d)le extent and richness, and they will doubtless be developer! as soon as the railroad has been completed. A deposit of phosphate rock has l)een reported near San Diego, Cal., but the samples sent east showed a. small proportion of phosphoi-ic acid and a large content of calcium carbonate. In Georgia, accoixling to S. ^\\ McAllie, the only commercially important phosphate deposit is near P>oston, Thomas county, which was discovered in ISSl). The phosphate occurs in nodules of a size ranging- fi'om I inch to 1 foot in diameter, scattered promiscuously through a rcnldisli sandy clay overlying an irregularly PHOSPHATE ROCK. 929 eroded surface of limestone. In addition to the nodules, which contain from 70 to 78 per cent of tricalcic phos- phate, there is also a small proportion of soft phosphate rock. A few carloads of rock were produced in 1SS'.», but the work was abandoned on account of the small quantit_y of rock available and the great thickness of the overburden. A small ((uantity of phosphate rock is mined annual!}' at the shell-rock quarry. Castle Haj'ne, near Wilming- ton, N. C. The state owns the mines, and in 1S!»7 pro- posed to work them with convict labor. In 1S98 a land and improvement company was organized to take ovei' the property under contract with the state. During recent j^ears the entire product, which is of very low grade, has been used solelj' for macadamizing the streets of Wilmintj-ton. The phosphate mines at Ro.ss Farm, Juniata country, Pa., on the Tuscarora Vaiie}' Railroad, are operated by a fertilizer company, wliich erected a large plant for the manufacture of acid phosphate in 1898. The aver- age rock is of low grade, but the good rock, containing more than 50 per cent of tricalcic phosphate, can be easily separated from that of poor grade. The phos- phate b(>ds dip ,steeply into the mountain, and the rock can 1)6 delivered at the works, 300 vards distant, at a very low cost. In Virginia the occurrence of deposits of hard-rock phosphate was reported in Nelson county in 1893 and in Rockljridge count}' in 1894. An anal3'sis of samples showed that the material was of high grade, but the deposits examined were so inaccessible and small that the rock could not be mined at a profit.

D. The statistics foi' the sulphur and pyrite industries have been united in tlie present discussion in order not to disclose the operations of 1 company engaged in pro- ducing sulphur. Table 1 is a summary of the com- bined statistics for these i! industries in 18S9 and 1902, and of the statistics of pyrite alone for ISSO, no returns for sulphur mining having been made for that 3'ear. The expansion of domestic production to meet the increasing demand for sulphur and sulphuric acid is clearly indicated.

For the twenty-two years covered, the table shows an increase in production of over one-hundredfold, and in value of nearlj' one hundred and ninetj- fold. When the total amount of sulphur consumed (as sulphur, not including pyrite) is taken into considei'ation, the amount of the domestic production in 1902 was not relatively large, but the steadj- increase indicates the substantial nature of the industry. In 1880 the industry was small — only 1 pyrite mine with a product valued at $5,000 being reported, but in 1889 the value of the production of sulphur and pyrite was $209,969. This increased to $917,089 in 1902. The growth from 1880 to 1889 was greater proportionately, but that from 1889 to 1902 was larger in absolute amount. Three sulphur mines were reported idle in 1902 — 1 in Colorado and 2 in Utah; and 5 pyrite mines — 1 each in Alabama and Ohio, and 3 in Virginia. At 1 sulphur mine in Texas development work was reported. Capital stork of Incorporated comparueH. — Of the 18 operators in the United States in 1902, 14 were organ- ized as incorporated companies.

The average number of wage-earners for the entire year was 970. The highest monthly average, 1,059, reported in July, exceeds this by only 89, and the low- est, reported in December, falls short of it by 151, a total variation of 240, or 24.8 per cent of the yearly average.

In no year during the period co\'ered by tlic table lias this ]iropi;rtion exceeded 3.8 per cent, but a comparison of the fluctua- tion makes it e\'i(lent that this proportion tends to increase. The imports have increased from S8,119 long tons in bSSO to 174,939 long tons in 1902. I'racticaliy all the yjyrite consumed in ls,82 was of domestic production, Ijut in 1901 this source yielded only 3(;.S per cent of the total. Owing to trade condi- tions the foreign pyrite can be more ])roHtablv util- ized than can the domestic ore. Hence the imports have constantly grown until they now form almost two- thirds of the total consumption. The recovery of the sulphur content of pyrite has steadily encroached upon the field formerly occupied almost exclusively by sulphur. EstimatiHl on an aver- age suli)hur content of 45 per cent, the (|uantity of sul- phur displaced by the use of jiyrite has grown from SULPHUR AND PYRITE. 935 93,233 long tons in 1891 to 287,339 long tons in 1901.

It is one of the most important elements that comprise the earth's crust, and occurs in a free or uneombined state in many countries, forming the mineral sulphur, more commonly known in com- merce as brimstone. Pliysicid. and chemical cJiaracteristics. — The element is insoluble in water and nearly so in alcohol and ether, but is quite soluble in carbon disulphide, petroleum, and Ijenzine. It burns in air with a blue flame, and is oxidized into sulphur dioxide or sulphurous acid. It exists in two distinct crj^stalline forms, and also as an amorphous varietj'. These modifications are character- ized by differences in specific gravity, in solubility in various liquors, and in manv other respects. Sulphur is a pale-yellow, brittle, crystalline solid, with a resinous luster, is almost tasteless, and emits a peculiar characteristic odor when rubbed or warmed. It is a nonconductor of electricity and an extremely bad conductor of heat. When A-ery gently warmed, even by being grasped in the hand, it may be heard to crack by the mere warmth, and will ultimately fall to pieces. At a temperature of 114.. 5^ C. it melts into a clear amber-colored and moderatel.v mobile lic^uid; on rais- ing the temperature of this liquid, its color rapidly darkens, and at the same time it loses its mobilit_v until 936 MINES AND QUARRIES. at a temperature of about ^oO"^ C. the iiias.s appears almost black, and is so viscous that it can no longer be poured from the vessel. As the temperature is still further raised the substance, while retaining its dark color, again becomes liquid, although it does not regain its former limpidit3\ At 448- C. the liquor boils and is converted into a pale yellowish-brown colored vapor. In cooling the same changes occur in reverse order. The atomic weight is 32. The specific gravity of ordi- narj^ octahedral sulphur is 2.05; of prismatic sulphur, 1.96. Usen. — Sulphur is used in the preparation of sul- phuric acid, in the manufacture of gunpowder, in making friction matches, in vulcanizing rubber, as an insecti- cide, and in medicine as a laxative, and for certain skin diseases. 2Linerals of sulphur. — Sulphur occurs in combination with other elements, forming the large and in)portant groups of minerals, the sulphides and the sulphates. Of the sulphide minerals, the combinations with the metallic elements are of primary industrial importance, and, with the possible exception of the iron sulphides, they form the ores from which many of the base metals are obtained.

Chief sulphate minerals: Sulphur and calcium Sulphur and barium Sulphur and magrnesium Sulphur and strontium Important artificial sulphates: Sulphur and copper Sulphur and iron Sulphur dioxide (SOJ is the direct combination of sulphur with oxygen and is found naturally as a minor constituent of the atmosphere, particularly near vol- canoes, and over large cities, where its presence is due to the oxidation of the sulphur contained in the fuel burned. In vegetables sulphur exists in some of the tissues of plants, although not in the woodj' tissues. In animals it constitutes an essential element of the blood, umscles, skin, hair, and other parts. Hydrogen sulphide (H^S) and sulphur dioxide (SOo) are evolved from volcanoes as gases, which are doubt- less the products of the action of the water of the ocean which has penetrated to the interior of the volcano upon the molten metallic sulphides that exist there. The two forms in which the sulphur is marketed are the flour, or flowers, of sulphur, which is a light pow- dery form of the substance caused by the condensation of sulphur vapor; and brimstone, or sulphur, which is made usually by melting this soft powder and mold- ing the liquid thus obtained into large blocks or cylin- drical rods in wooden molds. (Jccurrencv. — Natural deposits of sulphur are some- times found stratified with beds of clay or rock, but they often occur as what are known as ''living" beds, in which the sulphur is continuously being formed as the result of active chemical decompositions. l\\ such a living sulphui- bed the sulphur is produced ))v the direct action of sulphurous gases, especially hydrogen sulphide (H,S) and sulphur dioxide (SOo), which in the presence of moisture (H.,0) react and form water (H^O) and sulphur (S). These gases emanate in regions of active or expiring volcanoes, and form the so-called solfataras, in which the suli:)hur has been condensed from the vapors formed and has collected in cracks in the lava and tufls or in the kaolin or clay formed by the corroding action of the acid vapors on the lavas. From a commercial standpoint, especially for the manufacture of sulphuric acid, the mineral from the solfatara deposits is not regarded favoral^ly on account of its liability to contain arsenic in the form of the minerals orpiment (AS2S3) and realgar (AsS). Sulphur of this character has been imported from the island of Vulcano, one of the Lipari group, ofl' the coast of Italy. A similar association of arsenic minei'als has been re- ported in the sulphur deposits in Yellowstone National Park. Traces of selenium and tellurium, which are also objectionable in the manufacture of sulphuric acid, occur in the volcanic sulphur deposits in Japan. The only solfatara deposits of conmiercial importance at the present time are in southern Utah and in the island of Hokkaido, Japan. The world's supply of sulphur is derived from two principal sources: (1) The deposits of the native mineral sulphur, which 3'ield the sulphur or brimstone of com- merce; and (2) the deposits of the sulphide minerals — pyrite, pyrrhotite, chalcopyrite, sphalerite, and other sulphides — from which is derived the sulphur dioxide gas used in the manufacture of sulphuric acid. In addition to these two natural sources of sulphur, there are several artificial products containing sulphur, chiefly in the form of sulphur dioxide gas, in sufficient quantity to admit of commercial utilization. There are also lead, copper, and other mattes from the furnace SULPHUR AND PYRITE. 937 treatment of various lead and copper ores and alkali waste from chemical works cngag'ed in manufacturing soda. During recent \'ears, however, several thousand tons of sulphur have been produced annually in Eng-jand from the accumulated alkali waste of the Lc Blanc soda process. This manufactured product is known as "chance-claus," or recovered sulphur. The process of its manufacture reproduces, in many respects, the chemical reactions hy which natural sulphur is formed from gypsum. KEVIEW OF THE INDUSTRY IN THE UNITED STATES. The development of the sulphur mining industry in the United States has been of very slow growth, owing principally to the cheapness with which the refined product can be imported from Italy. In recent years nearly the entire supplj^ has been obtained from the enormous deposits in the island of Sicily, which sup- plies, as well, by far the greater part of the rest of the world's demand. The deposits of sulphur which have been worked in the United States are limited in num- ber. The states from which, during 1902, the domestic supply of native sulphur was derived are, in the order of the quantitj' of their output, Louisiana, Nevada, and Utah. The following is a brief summarization of the prog- ress that has been made in extracting and refining the sulphur of the deposits in this country. Louisiana. — An immense deposit of sulphur of the g.vpsum t3-pe occurs in Calcasieu parish, 230 miles west of New Orleans and 12 miles from Lake Charles. This is unquestionably the most accessible of the American deposits, and, in all probability, it is the richest as well. Exceptional difficulties have been encountered in devel- oping the mine, owing to quicksand and gravel which overlie the mineral. As proved b}- a number of drill holes, the bed of sulphur is from 110 to 125 feet in thickness, the upper level being about 350 feet below the surface. In the working of the Frasch process,' a well is sunk by a drill precisely in the same way as for petroleum.'' This well is cased with an iron pipe 10 inches in diame- ter, which enters the rock overlving the bed of sulphur for a distance of 10 feet, the joint being subsequentlv sealed as well as possible bj^ molten sulphur in order to exclude water. Inside the 10-inch pipe is placed one of 6-inch diameter; inside the latter, one of 3-inch diameter; and, finally, inside the 3-inch pipe, one of 1-inch diameter. The well itself is carried down to the bottom of the sulphur bed, and the 6-inch and smaller pipes are extended nearly to the bottom of the well. The inner pipes are recovered when the well is abandoned. The method of extracting the sulphur is ' United States patents, Nos. 461429, 4614.30, and 4614.31 of Octo- ber 20, 1891. ^The Mineral Industry, Vol. V, pages 514 and .515. as follows: Steam at a temperature of 330'-' F. is forced down the 10-inch and 6-inch pipes imder a correspond- ing pressure. When the steam comes in contact with the sulphur (which at 281:'-' F. becomes liquid), the lat- ter melts and collects in the well as a thin liquid of a specific gravity of about 2. At iirst the molten sulphur was pumped out through the 3-inch pipe in a manner similar to that followed in pumping petroleum from a well, the working valve ijeing formerly of aluminum, which is not affected bj' sulphur. It was found, how- ever, that the aluminum was not strong enough to with- stand the shock of the heavj' column at the change of stroke, and the method had to be abandoned. Later, the 1-inch pipe referred to above was introduced into the 3-inch pipe, and through it comj^ressed air was forced. The bubbles of air mixed with the sulphur reduce the specific gravitjr of the column of sulphur and cause it to rise with rapiditJ^ This latter method of extraction has not been entireh' satisf actor}-, and it may have been modified or replaced by some other more efficient method. The sulphur produced is prac- tically refined sulphur, and finds a readj' sale on account of its purit}- and attractive appearance. It is not practicable to ascertain preciselj' what occurs at the bottom of the well, but it may be assumed that as the sulphur melts out of the bed it forms a more or less pear-shaped cavit}', which becomes larger and larger, until finally the increased surface exposed to the water is sufficientlj' great to reduce the temperature of the water below the melting jDoint of the sulphur, while the impurities of the bed collect on the bottom and the sides of the chamljer and i^rotect the sulphur still unfused from the melting action of the heated water. If the bed of sulphur is very pure the chamber might become quite large in size, when the imsupjjorted overlying roof would fall and allow the water to escape through the overlying beds. Although the Frasch process is verv ingenious and the inventor deserves great credit for working out the numerous details, j^et its application to the deposits of sulphur has greatly injured them, since the exploita- tion of the deposit by shafts and the common method of underground mining has now become fraught with danger, owing to the uncertain extent of the openings from which the sulphur has been dissolved by the Frasch experiments. In view of the heavy flow of water which may be expected through certain of the strata this uncertainty is an element of great peril. Nevada. — Sulphur occurs at Rabbit Hole Springs, 35 miles from Humboldt House, in Humboldt county. The deposit is of the solfatara type; and the sulphur, associated with gypsum, etc., tills the craters of a few extinct hot springs. The sulphur rock is in beds of considerable thickness and extent, included between limestone and magnesian rocks. The ore occurs in masses of various sizes up to several hundred pounds in weight, which are mixed with clay among heaps and 938 MINES AND QUARRIES. lawyers of ashes and light gravel. The ore is iiiineil b3' adits and drifts run in from the level of the wagon road, which extends entirely around the hill at a con- siderable elevation. All rock containing more than 8 per cent of sulphur is mined, and the product is taken to the refinery and refined in iron kettles heated by dry steam. The refined product is carried in wagons to Humboldt House and shipped thence by rail, chiefly to the powder factories and acid makers on the Pacific coast. TJtali. — The deposits which are the source of most of the sulphur mined in Utah are located in Beaver county near the Millard county line. They were known to the earh' pioneers, who obtained small quan- tities of almost pure sulphur from the numerous caves in that vicinity. Soon after the year 1870 the claims were located under the mining laws, and a small refin- ing furnace was installed which was worked intermit- tentl_y until the j'ear 1891, when the property changed owners, and the plant was modernized and enlarged. Under the new management, the mining operations of the company have been continuous and successful. The ore is removed by open cutting, and the furnaces are worked daring the summer on)}-. Four of the six stacks in the refining plant are generally operated at a time, and about 50 tons of 2U per cent rock are treated daily, yielding the refined product in the form of roll sulphur, which is sold as such or is ground in mills to make flour sulphur. Deposits in other states and in Alaska are thus described: AlasTiCi. — There are a number of sulphur deposits of the solfatara type on the volcanic islands off the coast of Alaska. The largest so far as known is on the island of Kadiak, but others are recorded on Unalaska and Akutan islands, and on an unnamed island south- east of Akun Island. The deposits have not yet been exploited beyond the prospecting stage. Oalifornlii. — At Sidphur Bank, on (.'lear Lake, 40 miles north of San Francisco, a deposit of sulphur oc- curs in the white siliceous residue of a basalt flow that has been decomposed by the uprising solfatara and the sulphur deposited. Some 2."i years ago this deposit contributed a small ({uantity to the domestic supply of the United States, but as the development work \\'ent deeper cinnabar was found, and sulphur was no longer produced. A deposit of sulphur was worked for a time in Colusa county, and a small refinery was erected, but during the past decade little, if any, sulphur has been produced in this comity. The occurrence of sidphur has also been reported in other localities in California, but nowhere in suflicient cjuantity to warrant its extrac- tion as a conunercial product. [iliilid. — The occurrence of sulphur has been reported near Swan Lake, Custer county, and also near Sf)da Springs, in Bannock county. The deposits have not yet been developed to any great extent, although there was a small output in 1901. Te.vas. — The sulphur deposits in the. northeastern part of El Paso county have Ijeen known since 185-1:, when the}' were noticed by Prof. William P. Blake, who was then the geologist of an expedition for the surve}' of a railroad route from the Mississippi river to the Pacific ocean, which was made by the United States AVar Department. The region in which the deposits occur is from 13 to 60 miles from the railroad. The nearest ]-ailroad station, Guadalupe, on the Pecos Valley Railroad, is 42 miles north of Pecos. The sul- phur occurs in the form of small cr3'stals embedded in white gypsum, and in some instances the ore contains as nmch as 25 per cent of native sulphur. The area of the region thus far prospected is small, but there are other localities of promise awaiting examination. MetJuid of refininij sulpliiir. — It has been proposed to separate sulphur from the ore b}' heating it with hot air, with steam under pressure, or with superheated steam. But these methods have been unprofitable on account of the cost of fuel in those regions where sulphur occurs. Sulphur may be extracted from the ore by a solvent, such as carbon disulphide, which may be recovered after- wards, but this method necessitates an expensive plant. For some ores a treatment with a solution boiling above the melting point of sulphur has proved successful. The ore is placed in an iron basket or crate in a boiling solution of calcium chloride,' which boils at 125- C. The sulphur melts and flows away from the matrix of stones, etc. ; passing through the meshes of the basket and falling to the bottom of the tank, it is drawn off' and cast in molds. After it is melted out, the basket of hot stones is lowered into a tank of water, which is heated Ijy the stones, while it removes the adhering calcium chloride from them. This warm water is then used to replac(> that lost from the boiling calcium chloride solution. This process causes no loss of sul- phur as sulphur dioxide, and no nuisance is created, while a fairly pure product is obtained. The calcium chloridt' used is a waste product of the annnonia soda industry. In the United States, the extraction of sulphur bv means of superheated steam" has been tried, and an excellent (juality of sulphur has been obtained without formation of any sulphur dioxide. The cost of fuel in the West, however, is an obstacle to the further devel- opment of this method. In Louisiana, as mentioned earlier in this paper, steam is forced, under pressure, through driven wells or tubes, into the sulphur deposit, which partly refines the sulphur, li(juefied by the heat. The molten product is forced to the sui-face l)v the 'Vincent: Bull. Sec Chini., 40, 52S. Am. Cliem. .Tour., VI, (i;5 M. Soc. t'heui, Ind, 1887, 4.':i9, 442; 1S8!», 6;»6. SULPHUR AND PYRITE. 939 steam pressure throujifh a small pipe inside of the steam pipe. Generally the method of extraeting- the sulphur from the ore, and at the same time of partially refining- it, is to treat the ore in a cylindrical or slightly conical cast- iron vessel of a capacity of about 5 tons of ore. Steam inlets are provided at the top and l)ottom; also a bottom valve through which the melted sulphur is withdrawn and cast into molds. The size and the form of this retining vessel depends to some extent upon the natui-e of the material to be treated. If the ore is porous, n higher vessel of greater capacity can ])e used, and with ores that increase their volume considerably from the action of the heat, the bottom of the vessel should V)e made of much larger cross section than the top, in order to facilitate the discharge of the spent ore after the sulphur has been extracted. The steam jets are so arranged that the melted sulphur can not accumulate at any point within the vessel except at the bottom. If properlj' arranged and operated the extraction of sul- phur by means of superheated steam should be accom- plished with the loss of not more than from 1..5 to 2 per cent of the quantity of sulphur treated. Sidpliur dejwsits of Italy. — Owing to the importance of the sulphur deposits of Ital\', the following- brief outline of the methods of mining and retining adopted in that country will be found of interest.^ In Sicily the sulphur mineral is disseminated through the matrix, sometimes in considerable masses of nearly pure sulphur, but usually" in tine seams or grains. The methods of obtaining it are very crude and wasteful. The mines are for the most part open pits, ranging from 200 to .500 feet in depth, and the ore is carried to the surface in baskets or sacks by laborers, who ascend bv inclined paths on the walls of the pit. In a few of the better mines, however, hoisting machinery is now used, but the introduction of this method has met with the determined oi)position of the laborers. The ore is generally refined in a ver_v simple manner, the process being carried on in kilns called "calceroni." As usually constructed, these are shallow pits about 30 feet in diameter, with walls about 10 feet high, made tight with mortar. The}' are generallj' built on a hill- side, and the sloping bottom is beaten smooth. The ore is arranged in the calcerone so as to leave a few vertical draft holes from top to bottom of the heap, which is fired by dropping burning brush or straw into these openings. The sulphur, which forors from 2.5 to 40 per cent of the ore, burns freely, and when the heap is well on fire the draft holes are closed, the calce- rone covered with spent ore, and the whole left for several days. The heat given out by the burning of part of the sulphur is sufficient to melt the remainder from the gangue, and it collects in a pool near a tap ' F. H. Thorp: Outlines of Industrial Chemistry, 1898. hole made in the wall at the lowest point. At intervals of a few hours the melted sulphui' is di'awn off into molds. If the temperature rises above 180" C. (3.56" F.), there is a large formation of j)lastic sulphur, which will not flow from the tap hole. The time necessary to bui'n out a calcei'one varies fi-oni thirty-five to eighty daj's, accoi'fling to its size, the weather, and the natui-e of the impin-ities; for example, much gypsum retards the proc- ess, owing to the water it contains. Usually from a ([uarter to u third c)f the sulphur is lost as sulphur diox- ide during the burning. As this causes nuich damage to vegetation in the vicinity, the burning of calceroni is prohibited during the spring and summer months. PYRITK. The name pyrite is derived from the Greek word nvpiTrfs meaning "of the nature of fire," and alludes to the property possessed by the mineral of producing sparks when struck with a hard substance. Specificall}'. the name pyrite is restricted to the isometric cr3'stal- line form of the native iron bisulphide mineral (FeS^) containing 46.6 per cent of iron and 53.4 per cent of sulphur. The mineral marcasite is also a native iron bisulphide (FeS.j) of identically the same chemical com- position as pyrite, but it occurs in crystals of the or- thorhombic system of crystallization. In a general sense, pyrite includes that class of native minerals in the mas.sive or crystalline form composed of a metallic sulphide or arsenide, or both. Iron, copper, nickel, and cobalt pyrites are the principal minerals of this class. Occurrence. — Pyrite occurs abundantly in rocks of all geologic ages, from the oldest crystalline to the most recent alluvial deposits. In crystalline formation it usually occurs in small cubes, pvritohedrons. or in more highly modified shapes; also in irregular spheroidal nodules, and in the massive form in clay slate, argilla- ceous sandstone, coal formation, etc. TIseft. — Pyrite is used principally in the manufacture of sulphuric acid. Recently it has also l.)een used in pyritic and allied smelting processes and, to some ex- tent, in making sulphur dioxide gas for use in bleach- ing wood pulp. In vulcanizing rubljcr and in the preparation of medicinal compounds the use of pvrite is impracticable. .Deposits and iiiiiihuj in tlie UttifeJ Stntis. — The de- posits of pj'rite in the ITnited States are quite numer- ous and widespread. The largest deposits so far dis- covered are at Mineral, Va., and Charlemont, ^lass. Deposits are also found in Alaljama. California, Geor- gia, Indiana, New York, and Ohio. The mineral was mined in these states in 19(J2. Virginia supplied nearly one-half of the total. The production in Indiana and Ohio was in the form known as "coal brasses," ob- 940 MINES AND QUARRIES. tained as a by-product in the mining of coal. The total quantity so produced, however, was but a small pro- portion of the total output of the United States. It is not probable that the production of pyrite from this source will ever become of importance. There are many other deposits of pyrite in the United States, but thev have not been exploited because of the impure or low-grade quality of the ore and the excess- ive cost of mining and of transportation both to and on the railroads leading to the centers of consumption. Some of the ores not now deemed of sufficient value to be worked for their sulphur content will eventually be profitably treated by modern methods. In the Southern states particularly are niany deposits of this character, which could produce enormous amounts of sulphuric acid in this manner at prices lower than the present average prices at the seaboard. A condition which has served to retard the growth of the production of the domestic ore lies in the fact that foreign ores can be imported and accumulated at the seaboard and shipped inland in quantities sufficiently large to secure very low freight rates. A promising prospect for the pyrrhotite ores of the South lies in the feasiVjility of their utilization for the manufacture of sulphuric acid. ' It is claimed that the sulphur contained in these ores can be so efi'ectually I'emoved that the residual product will be of value in the manufacture of pig iron or even of steel. For this purpose the cinders or residues from the roasting of P3'rite for the manufacture of sulphuric acid have been utilized to advantage. It is well known that the resi- dues from Spanish ores treated by the Henderson proc- ess have been sold either in the form of ''fines" or " briquetting " and utilized in the manufacture of steel, but in the United States roasted pyrite residues have not yet been utilized for the manufacture of iron on account of the large percentage of sulphur remaining in them after treatment in the chemical works. If pyrite residues could be roasted so that the amount of sulphur remaining after treatment would be so small as to permit of their utilization for the manufacture of pig iron, there would result an annual saving of many thousand tons from what is now a waste pi'oduct. As 3-et, however, the recovery of sulphur and iron from these ores is in an experimental state. Other experiments have recently been conducted for the utilization of the V)y-product gases resulting from the roasting of zinc blende ores, the practicability of which has been demonstrated with financial jjrofit at the zinc plants of Peru and Lasalle, in Illinois, and of Argentine, in Kansas. It is feasible to save from 25 to 28 per cent of the sulphur content of the zinc ores during the roasting, which yields a product containing not more than 2 per cent of sulphur. By sub.secjnently roasting this product — cindei's, as it is called — in the Chase or other type of special roasting furnace the re- mainder of the sulphur will be expelled, and the dead- roasted zinc ore will then be in proper condition to permit of the extraction of the zinc at very low cost. There is an immense supply of sulphur in the zincifer- ous sulphide ores of Arkansas, Colorado, Kansas, Ken- tucky, Missouri, and other states, and it is well within the range of probability that ere long the tonnage of sulphur derived from pyritiferous ores will be largely augmented by the utilization of the sulphur contained in these zinc sulphide ores. An important factor in the development of the pyrite industry is the demand for sulphuric acid in the treat- ment of phosphate rock, and in the refining of petro- leum. Since a chemically pure sulphuric acid is not essential for these purposes, the acid made from pyrites serves quite as well as that made from sulphur. An- other field for the future extension of the utilization of the pyritiferous ores lies in the making of sulphur dioxide gas for use in bleaching wood pulp, which is the basis of the manufacture of paper by the sulphite process. Heretofore American manufacturers of paper using this process, with one or two exceptions, have been limited to the use of sulphur for making sulphur- dioxide gas, although in Europe a considerable quantity of pyrite has been thus utilized. It is tpiite probable that the difficulties that have heretofore existed in the way of utilizing pyrite in the l^lcaching of pulp will be overcome in the near future. When this l)ecomcs an accomplished fact it will open up a large field for the consumption of pyrite in New York state, and also of the lean cupriferous pyritic ores of the New England states. Where the -conditions are favorable for deep mining and concentration and for shipment to the nu- merous paper mills of that section, constant and large supplies of sulphur will thus be guaranteed at prices much lower than can be expected from outside sources. THE MANUFACTURE OF SULPHURIC ACID. The manufacture of sulphuric acid is of great indus- trial importance, as the acid is of primary importance in the manufacture of phosphate rock fertilizers and in the refining of petroleum. It is also required in the manufacture of other acids and chemical salts, and has a veiy wide field in the making of alizarin dyes, arti- ficial indigo, and man_v other important chemical salts. Of the immense ([uantities of sulphuric acid made yearly, the greater part does not appear on the market; because of the expense and difliculty of shipping it, consumers of large amounts generally make their own acid. Until a few years ago the total ([uantity of ordinary sulphuric acid produced in the world had been obtained by burning crude sulphur in air, the resultant sul- phur dioxide gas l)eing then passed, together with SULPHUR AND PYRITE. 941 steam and an oxidizing agent, generally nitric oxide, into lead-lined ehamljers, Avhere these gases react on one another and form the dilute acid, which is suljse- quentlypuritied and concentrated to the tlcsircd degree of strength. This process is called the lead-chamber process, but a newer and more satisfactor}' process is the '"contact" process, in which the sulphur dioxide gas, in the presence of so-called "catalytic" substances (platinum sponge, platinized asbestos, iron oxide, etc.) is directly oxidized to sulphur trioxide (SO,), wdiich is then absorbed in water to form sulphuric acid of any degree of strength. Recentlj' it has l)een found more economical in making sulphuric acid to utilize the sulphide minerals as the source of sulphur diox- ide gas. In this manner the more costl3' brimstone is reserved for purposes other than acid manufacture, and for which the sulphide minerals would not be appli- cable. The use of pyrite as a raw material in the manufac- ture of sulphuric acid was first proposed b}' an English- man named Hill, who obtained a patent for the process in 1818. It was not until 18.38, however, when the price of crude sulphur was nearlj^ trebled by the French firm who had purchased from the Sicilian government the monopoly of the sulphur exportation from that island, that the use of pyrite by acid makers attained anjr importance. In the United States, which leads the world in the consumption of sulphur, this substitution of pyrite for sulphur in acid making has continued steadilv during the past twentj^-five years, and owing to its cheapness and widespread occurrence, pyrite has almost completely replaced the crude sulphur that was formerly used almost exclusively. This change in acid making has resulted largelj' from the treatment of phos- phate I'ock b}^ sulphuric acid, by which it is made into valuable fertilizer, and also from the use of the acid in the refining of crude petroleum. For these purposes the use of a high-grade, pure sulphuric acid is not essential. Unrefined sulphuric acid made from pyrite is generally contaminated with arsenic, and frequently with the additional impurities, copper, zinc, and sele- nium, but not in suflicient quantities to bar its use in preparing fertilizers or in refining the crude petroleum. The impurities, too, may be removc^d if desired, and a pure acid produced. To give some idea of the large (juantitics of the acid consumed in these industries, it may be stated that 1 pound of acid of chaml)er strength is re(juired to con- vert eadi pound of crude phosphate I'ock into acid phos- phate or conmiercial fertilizer, and duilng 1902 over 1..50(),()O(.) long tons of the crude phosphate rock were mined. In refining crude petroleum each gallon of commei'cial petroleum (kerosene) requires 1 pound of sulphuric acid of a strength of 66^ B. for its produc- tion, and during 1902 the output of crude petroleum in the United States amounted to over 89,000,000 barrels, each of ■42 gallons capacity. In estimating the quan- tity of acid consumed in these two industries alone, any calculation based upon figures of production, less im- ports, both of crude petroleum and phosphate rock, nmst necessarily be tentative and not even closely approxi- mate, for the reason that it is impracticable to ascertain the exact quantities of stock of crude material on hand at the beginning and at the close of a 3rear. For prac- tical purposes, however, it ma}^ be assumed that the consumption of sulphuric acid in the United States at the present time is approximately in the following pro- portions: For the treatment of phosphate rock, .50 per cent; for refining crude petroleum, 38 per cent; and for use in the chemical trade, 12 per cent. In making sulphuric acid from pj'rite, pieces of the mineral ranging in size from several inches in circum- ference to extreme fineness are burned with access of air in a furnace, of which there are many forms, each suited for some special physical or chemical character- istic of the ore. As a result of the burning, or oxida- tion, the sulphur content of the p3a-ite or pyritiferous ore is converted into sulphur dioxide gas. ^^'hen the ore contains over 30 per cent of sulphur, the heat gen- erated by the oxidation of the sulphur is suflicient to maintain combustion without fuel. The sulphur di- oxide gas produced in this manner is purified, and sub- sequently converted into sulphuric acid, either bj' the chamber process, in which the oxidation is accomplished by nitric oxide gases and steam, or by the contact proc- ess, previousl}' described. 942 MINES AND QUARRIES.

The mining of barytes lias been carried on in the United 8tates for about lifty years, but it is still an industry of minor importance. Barytes was first pro- duced in small quantities for use as an adulterant of white lead. Statistics of production for 1902 are pre- sented in Table 1, with such facts as are available for the censuses of 1860, 1870, 1880, and 1890. Table 1. — Frodwtio)i of hurytes: IS/JO to lUOS. CENSUS.

Missouri, Virginia, Illinois. Missouri, North Carolina, Tennessee, Virginia. At the census of 18()0 the statistics of this mininy- industr}' were not separately reported, but were in- cluded among those for manufactures. Returns were given for 1 barytes establishment in Westchester county, N. Y., which had 40 employees, who received §12,000 in wages. The cost of materials was given as $5,000, and the value of product as $25,000. The only statistics reported for this industry at the census of 1870 were those of 1 establishment in New Haven county. Conn., which employed 110 men, all above ground, to whom $78,000 was paid in wages. The cost of materials was $5,518, the capital $50,o00, and the value of the product (quantity not stated) |llO(;i,000. The deposit, which was located at Cheshire, had been mined qidte extensively, as is shown liy the old workings. At the census of 188(.> the statistics for barytes were shown under minor minerals, and a total of 6 mines was reported for the states of Georgia, Missouri, Penn- sylvania, and Virginia. These employed 63 wage- earners, to whom was paid §7,81)2 in wages. The cost of materials was given as only $200, making the total cost $8,002 for the production of 3,608 tons, which .30223—04 60 was valued at $37,491. This is an increase of $12,491 in the value of the production of 1880 over that of 1860. At the Eleventh Census mining industries were shown separately, and included barytes. The statis- tics, however, for this mineral were not uniform for the whole country, and are not, therefore, comparable with those for 1902.' The quantity of barytes produced in 1889 was given as 21,460 short tons, valued at $106,313, an increase of 17,852 tons in quantity, and of $68,822 in value, over that for the year 1880. Most of this production was obtained from Missouri and Virginia, with a smaller amount from Illinois. At the census for the (.-alendar j-ear 1902, the quan- tity of barytes produced was given as 61,668 short tons, \'alued at $203,154, which is an increase of 40,208 short tons in quantity and of $96,841 in value, over the pro- duction reported at the census of 18!*0. In 1902 no product of barytes was reported for New York, Connecticut, Georgia, and Illinois, although these states were returned as producers at one or all of the censuses of 1860, 1880, and 1890. ' Barytes mining in Missouri is carried on in such a very irregu- lar manner that it i.s impossible to oljtain any relialjle statistics relative to labor and wages. Farmers mine it in off seasons; that is, when there is no farming to do they employ themselves and their liamls in getting out the barytes fcjund on their farms, haul it to the nearest tradesman, and receive in exchange dry goods, groceries, or other necessaries, or cash. The farmers thus" occupy time which would otherwise lie idle, and dispose of the liarytes at a less figure than it would pay to mine it systematically. The supply thus obtained is nearly sufficient to keep the mills up to their fullest capacity. A few mines are, however, operated with some degree of system, though for want of proper records it is necessary to estimatea con- siderable portion of the matter of labor and wages. The mines altogether give irregular employment to al.)out 580 men. The rate of compensation for foremen is al.iout ^2.50 per day, and for labor- ers from $1 to $1.50 per day. It is rarely, however, that the men make full time, and their daily earnings are reported at from 50 to 75 cents. From 75 to 100 women obtain the same sort of irregular employment, earning about 35 cents per day. Boys get from 25 to 30 cents per day. One mine was active nearly the entire year, but in most cases the number of days worked at the mines ranged from 125 to 200. One mine in Illinois employed 10 men and 2 women for 52 days. (Eleventh Census, Mineral Industries pace 745. ) ' (945) 946 MINES AND QUARRIES. The large increase in tiie use of white lead is one of the principal reasons for the increase in the production of ))arytes. This mineral was formerly considered simply as an adulterant, but it is now beginning to ))e recog- nized that it has qualities of its own that make it of value as a pigment, and when it is used in combination with white lead or zinc white, these qualities appear to advantage.

Of the 49 mines or quarries shown for litoi, 34 are in Missouri, 5 in North Carolina, 6 in Tennessee, and 4 in Virginia. These were controlled by 42 operators, of whom 16 were individuals, 20 lirms, and 6 incorporated companies. Each of 2 firms operated 4 mines. Mis- souri leads in this industrj-, with 69.4 per cent of the mines and 51.. 5 per cent of the value of the production. North Carolina is next in respect to the value, with 21.7 per cent, and Virginia third, with 19.5 per cent. Ten- nessee produced only 7.2 per cent of the total value of the production, although reporting 6 mines, which is 1 more than North Carolina and 2 more than A^ii-ginia.

EiiqjloyeeH and irnKp-s. — There were at the 49 mines or quarries a total average number of 364 employees, of whom 28, or 7.7 per cent, were classified as salaried emploj'ees, and 336, or 92.3 per cent, as wage-earners. Of the total amount, $145,444 reported as paid for salaries and wages by the 42 operators engaged in the production of barytes, $130,285, or 89.6 per cent, was paid to the wage-earners and $15,159, or 10.4 per cent, to the salaried emploj^ees. The classification of these 364 salaried employees and wage-earners is shown in Table 6. Of the 821 wage-earners classified as miners or quar- rymen, onlj- 51, or 15.9 per cent, were emploj-ed below ground, of which 31 were in North Carolina, 16 in Vir- ginia, and only 4 in Missouri, although the latter state produces over one-half of the total production. This is due to the entirely ditferent occurrence of the depos- its of liarytes in North Carolina and Virginia as com- pared with those in Missouri. In the latter state the deposits occur near the surface, so that they can be worked almost entirely by means of pits and open cuts, while those in Virginia and North Carolina have to be ■worked largely bv means of shafts, tunnels, and drifts. There was obtained from those mines reporting wage- earners below ground a production of barytes valued at $62,900, or 31 per cent of the total value.' The total underground wage-earners numbered 52, or 15.6 per cent of the total wage-earners, and their wages consti- tuted 12.1 per cent of the total wages paid. The 8 wage-earners shown under "all other wage-earners'' are laborers who handle, load, and haul the ore and do miscellaneous work. There were on an tiverage 7 wage-earners to a mine or quarry. In addition to the number of regularly em- ployed wage-earners, 10 were employed in contract work in North Carolina at an expense of $1,000. They worked altogether a total of one hundred days. The number of wage-earners employed during each month, and their daily rates of pay, are shown in Table 6. The busiest month of the year for the industry as a whole was the month of May, when a total of 443 wage-earners were at work. August was the next bus- iest month, with 441. The least active month was De- cember, with 144. Many of the companies in Missouri employ no regular miners, the work being done by the farmers of the neighborhood who work in the mines at odd times. The company pays them for the ore dug. whether it comes in small or large quantities, or whether l:)y bucket, sack, barrel, or wagon load. Of the total number of wage-earners 321, or 95.5 per cent, are classed as miners. Of this number the wages of 135, or 42.1 per cent, ranged from $1 to $1.24 per day, and those of ti(i, or l^o.6 per cent, nuiged from $1.75 to BARYTES. 947 11.99 per day. The miner who received from $(J.60 to $(}.7i a da J' was emplo_yed in Virginia. The prevailing- wages for all classes of wage-earners was from $1 to $1.24 a dajr, there being 148, or 42. »ell county, where the mining is now carried on largely Ity means of shafts and drifts, have been worked almost continuouslv since isT-t. About 1»01 the deposits of Russell and Tazewell ccjunties were opened, and the latter gives prospect of becoming the largest producer of this min- (U'al in Virginia. The deposits of barytes that are being developed in Illinois are in Hardin county, and those of Kentucky are in Crittenden county. The growth of this industry has been partially dependent on the growth of the paint industry, in which a very large proportion of the barj'tes i^roduced is used. The baiytes has a pure white color, which is permanent, and it is unaffected by weather or b_v gases that in some instances blacken white lead, for which the barytes is used as a substitute. Besides the use of barytes in the paint industry, it is employed in the manufacture of paper and rope to give weight; and also in the prepara- tion of a material that is used to coat the canvas sacks in which hams are wrapped when ready for market. Another use for this mineral, and one that should increase rapidly, is in the manufacture of other barium compounds, principally the hydroxide. This compoimd was formerly prepared almost exclusively from the mineral witlierite, barium carbonate; but on account of its rare occurrence in commercial quantity, barytes has Itegun to be the raw material used in the manufac- ture of this hydroxide and other salts of barium. One of the greatest uses of the barium h^'droxide will per- haps be in the beet sugar industry, for the separation of the sugar left in the molasses. It is also claimed that the compound is api)licable in the cane sugar industry. Other uses consider(Hl for it are in the puri- fying of water used in steam boilers and in the prepara- tion (.)f hides for tanning. As these uses of barium hydroxide increase there should be a larger demand, and conse(iuently a lai'ger production of barytes. These multiplying uses for liarytes put the industry on a new basis, and take the mineral out of the list of adulterants with which it has l)een usuallv classitied. BARYTES.

CRUDE. Bj' Joseph Stkl'ther.s, Ph. D. As early a.s 1850 the census statistics of oclier, which is a subclassiticatiou of crude mineral pig-ments, appeared among- statistics of manufactures. There were only i! establishments, and they were in Vermont. In 18(10, 1 establishment was shown, also among manufacturing statistics, in Berkshire county, Mass. A census of mining industries was taken at the census of 1870. and ocher was included among stone qnarrj^ing industries. There were 4 establishments, all in Bennington count}-, Vt. Among- the mining industries at the census of 1880, 7 establishments were, given — 1 in New Jersey and 3 each in Vermont and Virginia — but, according- to a foot- note, there were a few ocher mines in Virginia or West Virg-inia from which no returns were received. At the Eleventh Census statistics were given among- mineral industries for ocher and metallic paint. The number of establishments was not stated. The states of Alabama, Colorado, Georgia, Maryland, Massachu- setts, Pennsylvania, Vermont, Virg-inia, and AVisconsin were shown for ocher, and Alabama, Colorado, New York, Ohio, Pennsylvania, Tennessee, and "Wisconsin for metallic paints. The statistics were for the year 1889 and apparently included statistics of the manufac- ture of ores into marketable paints. The substances included in this report, under the title ■' Mineral pigments, crude," are: Iron ores, hema- tite, or red iron ore (Fe.^0.,), and limonite of brown iron ore (FcoO.,, oii.,0); clay and other earths, comprising ocher (yellow, gray, and brown) umber (including Spanish brown), and sienna; soapstone, slate, and shale, utilized for making- certain shades of gray pigment; and gypsum, or mineral white, used as a pigment for printing- wall paper.

The state of Pennsylvania led in produc- tion, having 58.(5 per cent of the total (piantity and 68.3 per cent of the total value; the state of Georgia was next, with 1() per cent of the quantity and 13.1: per cent of the value; Maryland had 7.1 per cent and 3 per cent, respectively; New York reported 3.6 per cent of the quantity and 1.2 per cent of the value, leaving for all other states 14. 7 per centand 11.1 per cent, respectively. There were 13 mines reported idle during- 1902, con- trolled by 6 incorporated companies. 1 firms, and 3 indi- viduals. The 6 incorporated companies issued capital stock and bonds to the par value of $86,750, the total amount aixthorized being $96,750. Three of the mines were in California, 2 each in Georgia and INIissouri, and 1 each in Alabama, Michigan, Ohio, Pennsylvania, Ten- nessee, and Vermont.

Georgia was next with 25.1 per cent of the wage-earners and 18.4 per cent of the wages paid, the remainder being divided between Maiyland, New^ York, and "all other states." Of the total number of wage-earners in all the mines, 20.3 per cent wei'e under- ground. Penns3'lvania had 78.8 per cent of these under- ground workers and Georgia the remainder, or 21.2 per cent. The average number of wage-earners employed dur- i ing each month and their daily rates of pay by occu- pations are shown in Table 3. The number varied little the year through. The busiest months were aj^par- ently September and October, and the least busy, Feb- ruary and March. No particular skill or exi:)erience is required on the part of a miner in this industry', therefore the rates of pay should not be compared with those reported for miners where greater skill is necessaiy. The mines are worked by open pits, shafts, or tunnels, and in some cases the ore is ground, floated, dried, or other- i wise prepared for market at the mines. Of the total number of wage-earners, W), or 35.2 percent, are classed as miners or quarrymen, and 102 as "all other wage- earners."

MINEKAL PIGMENTS, CRUDE. 955 Product ion. — The United States Geoloj^jieal Survey has published annual statistics concei'iiino' the <[uantity and value of mineral paints, beginning with iSit-!-, and of some of the subelassitieations from various dates, })ut these statistics are not compara))le with those of the census, for the reason that they include the manufacture of the ore into paints and are not limited to the value of the crude ore at the mines. The Census statistics for 1903 include only that part of the manufacture which is done at the mines and which it is impossi))le to seg- regate, the mining and manufacture being in such cases accomplished with the same capital and undei' the same management. From the reports received for 1902, the various ores and claj's from which mineral paints were made ranged in value from f 1 (for red I'ock pigment) to $80 (for zinc white) per ton. The average value per ton was $10.17. Allowance must be made for the great variation in the average value due to the comparativeh' wide range in ([uantities and materials. The classification of crude mineral pigments includes yellow, gra}', and brown ooher, umber, sienna, zinc white, white mineral (gypsum), slate (sold for pigmentj, carbonate of iron and of zinc, oxide of iron, and other pigments. With ocher some of the previous censuses have included a little of umber and sienna. Ochers are known as those clays to which the natural mixing of iron peroxide and water has imparted a bright red or reddish-j^ellow color, while the iron 2:>igments are those from which the darker red or brown paints are made. In the statistics of production given at the census of 1902, there are bj'-products of 390 tons of soapstone used for pigment, valued at $2,810, and is tons of slate, valued at $525. The capital, wages, and other expenses attending the production are given under '"Talc and soapstone" and "Slate." A detailed sununary showing the statistics for crude mineral pigments during 1902 is given in Table 3. DESCRIPTIVE. Pigments are substances, }>oth natural and artificial, which are usually insoluble in water, oils, and other neutral solvents, and are used to impart color to a body either by surface adhesion or by direct admixture with its substance. Generally there is no chemical combi- nation between the pigment and the body it covers. When mixed with a drying oil, or with water containing oil or size, the pigments form the basis of paint which is used for decorative or protective purposes. The natural pigments, the only ones with which this report is concerned, are among the most important but are fewer in number than those prepared artificially by chemical precipitation or other processes. According to Thorp' the chief pigments are classified as follows: W/dUi: White lead, lead sulphate, lead oxy chloride, 1 Outlines of Industrial Chemistry, by F. H. Thorp. New York Macmillan & CV,., 1898, zinc white, zinc sulphide, barytes. gypsum, and whiting. liJiieK: Ultramarine, Prussian blues, smalt, cobalt ))lues, copper blues, and indigo. Vlolef: Ultramaiine. OreeiiK: Ultramarine, lirunswick green, ciu'ome green, (Juignefs green, copjjci' greens, and copper and arsenic greens. YMoim: Chi'ome j'ellow, yellow ocher, cad- mium 3'ellow, orpiment, litliarge, gamboge, and Indian yellow. Orange: Orange mineral, chrome orange, and antimony orange. Ri'(h: Red lead, chrome red, red ocher, Venetian red, vermilion, realgar, antimony red, and carmine. Btovmih: UmVjers, Vandyke Itrown, and sepia. Blaclix: Lampblack, ivory black, boneblack, and graphite. Iron oxide pigvienU. — The iron oxide pigments are used to make dark red or brown paints, Ijeing known in the trade as ''natural reds.'" They are classed as natural and artificial, the former (metallic paints and mortar color) being chiefl}' made from ))rown iron ore and ferruginous shales, and the latter (Venetian red, Tuscan red. and Indian red) from calcining copperas or copperas residues in a furnace yielding ferric oxide (Fe.jO.,) in a state of ver}- fine division. Although the occurrence of iron ores in the United States is widespread, and enormous deposits exist at many places, there are very few localities in which the material is of suitable physical and chemical composition for manufacture into metallic paint. The ores reported for use in the manufacture of metallic paint and mineral paint were mined in Anne Arundel and Baltimore counties, Md. ; Car})on county, Pa. ; James count}', Teim. ; Rutland county. Vt. ; Bedford comity, Va. ; and Dodge county. Wis. The mortar colors were all reported from Northampton count}-. Pa. Other iron pigments reported were mined in Cattarau- gus county, N. Y. , and Carbon and Wyoming counties, Pa. The Venetian red reported was all mined in Anne Arundel county, Maryland. The iron oxide paints are highly esteemed for some purposes on account of their freedom from poisonous ingredients which are found in some mineral paints, and because they resist to a marked degree the efl'ects of light, heat, and moisture, a quality which renders them of great value for outside or exposed work. Ochers in addition resist the destructive action of salt air, and are therefore of special value in localities at or near the seacoast. A certain proportion of metallic paint is used as a coloring matter in mortar making, and appears in some classifications under the title "mortar colors." The mining and preparation of the crude ore for the market are verj- simple processes. The ore, generallj- obtained bj- open-cut or quarrying methods, is disinte- grated by exposure to the atmosphere, carried to a mill, roughly crushed, dried, pulverized, and passed over a screen of bolting cloth or through some tj^pe of pneu- matic separator, from which the final product is classified and packed for shiyjment. At times the ground ore is 956 MINES AND QUARRIES. levigated and the settled products dried and packed for shipment. OcJierv. — The name ocher is applied to clays and other earth}^ bases containing in their natural state sufficient ferrous or ferric oxide or hydroxides to impart to the mass a bright red or yellowish-red tint. The color varies from a golden yellow to a dark red, occasionally possessing various tints of blue and green. The ochers reported were mined in Clay county. Ark. ; Calaveras and Stanislaus counties, Cal. ; Bartow and Richmond counties, Ga.; Berks, Lehigh, Luzerne, and Northampton counties. Pa.; Rutland county, Vt.; and Page county, Va. The sienna reported was mined in Washington county, N. Y., and the umber in Lawrence county, Pennsvlvania. The ochers have been used as paints from a very early date, the oldest applications positively recognized having been made in Italy, though it is believed that some varieties were in use still earlier by the Egyp- tians and Greeks. In modern times the ochers were first mined and prepared in Italy, and the siennas and umbers derive their names from the Italian towns in which they were manufactured into pigments. Ochers are classified in many ways, according to the locality of occurrence, the composition, and the sjDecial shade of color. Practical)}' thej' may be grouped into 3'ellow, red, and Ijrown. Yellow ocher is that which is colored by a ferric hydroxide. Red ocher owes its tint to ferric oxide, and it is therefore evident that red ocher may be prepared artificially by expelling the water from yellow ocher by calcining in a furnace or kiln. Brown ocher is red ocher modified by the pres- ence of black manganese dioxide, which in various proportions vields a large range of brown colors, nota- bljT sienna brown, umber, Vandyke brown, and man- ganese brown. The variation of ocher in shade and in qualit}' de- pends chiefly, but not entirely, upon the projwrtion of iron oxide present as well as the quantity of water combined with the iron oxide. A I'ed ocher, improperly called iron minium, very rich in iron oxide, is made by calcining and pulverizing limonite that is free from cliiv- There are few pigments more free from adulteration than the ochers, for the reason that any filler that can be used advantageously is more costl}' than the ocher itself. Sometimes a little chrome 3'ellow is added in order to improve the tone of a j^oor colored ocher, but the presence of this adulterant is \'ery easily detected. Oxford ochers are the brightest and best of the mineral pigments of this class. They are obtained from Oxford, England. The German pigments are often callwl ochers, although improperly so, for the reason that they are ligneous earths and not ferruginous (days. The manufactured prt^duct vai-ies greatly in quality and value, and some of the grades pass insensibly into umber or sienna. Umber and sienna in rcalitv are \-arieties of ocher which have been isolated on account of the brown color which is imparted to the natural clay material by the addition of iron and manganese oxides; raw umber is of a brown color, while burnt umber is of a somewhat richer and redder hue. Raw sienna is of a brownish yellow shade which affords a rich russet brown when burned. Intermediate shades of color are obtained by mixing natural products with various properties of iron and manganese oxides, and sometimes bj' mixing both raw and calcined materials together. The mining and .preparation of ochers, umbers, and siennas are similar to the practice described under iron oxide pigments, with the exception that at times the ground product, in part or wholly, is first heated in a furnace until the desired color has lieen obtained. In place of levigating and settling the ground material, it is sometimes passed through a pneumatic separator which yields an impalpabh' fine and uniform product.

Under the head of steel hardening metals are inrluded those metals used or experimented with in the hardening of steel, although some of tiiem arc used more generally for other purposes in the form of eompouTids. The metals belonging to this class are nickel, chromium, tungsten, molyl;)denum, titanium, uranium, and vana- dium. The statistics in this report relate to the pro- duction of the ore from which these metals are obtained, except that the tigur(>s for nickel and cobalt are for the matte made at the mines. In the mineral classifications, chromium appears as chrome ore, nickel as nickel and cobalt, and titanium as rutile.

The report for nickel is for the refined: for cobalt, the oxide prejiared from the ore; while Census figures are for the nickel and cobalt matte at the mine. Besides the mines reporting a production during 1902, 7 were idle. These have been worked to some extent during the past few yeai's, some of them becom- ing producers, while at others the woi'k has been that of development to prove the existence of ore in ([uan- tity. The uncertainty of the demand for most of the ores has been the principal cause of their nonproduc- tion. These idle mines were distributed, t>y states, a.s follows: Arizona, 1: California, 1; Colorado, 3; Nevada, 1; and Wisconsin, 1. They were owned by .5 indi- viduals and 2 incorporated companies. The total number of mines ciperated in 1902 was 12, distributed among 7 states, as follows: California, 1; Coloi'ado, (i; Connecticut, 1: Missouri, 1; Oregon, 1; Virginia, 1; and Washington, 1. Of these 12 mines, 4 — 3 in Colorado and 1 in Connecticut — produced tungsten, and 3 — all in Cohn-ado— produced uranium and vanadium. Where there are less than 3 operators mining any one ore they are included in "all others." Of the 12 operators engaged in the production of these metals, 8 were individutds, 1 a tirm. and 3 incorporated comjjanies. The total value of the outstanding capital .stock of two of the incorporated companies was $200,000, with no bonded indebtedness.

All the water- power was rented. A detailed summary showing the statistics of the pro- duction of steel hardening metals during iy()2 is given in Table 5. DESCRIPTIVE. CHROMK ORE. Chrome ore, or chromite, which contains the metal chromium, was the first of the minerals containing any of these steel hardening metals to be mined in the United States for commercial purposes. The discovery of chrome ore in this country was made about 1820' by Isaac Tyson, jr., at Bare Hills, Md., 7 miles north of Baltimore, but the deposit, being scanty and poor, was soon abandoned. He afterwards found the mineral at Soldiers Delight, about 15 miles northwest of Balti- more. In 1827 his attention was attracted by the ap- pearance in the market place of Baltimore of a man from back in the country who had in his wagon several lumps of a heavy black mineral which he was using to 'The :\rineral Industry, Vol. 11, p.«i(.'e 1.51. keep a barrel from rolling about in his cart." Upon testing the.se lumps. ]Mr. Tyson found the mineral to be chromite and learned that it was from Harford county, aliout 27 miles from Baltimore. This was the begin- ning of chrome mining in this countrv and of the chrome industrv of the Ty.sons, which was later supple- mented by manufacturing processes and has continued down to the present time. In the next year, 1.828, chromite w;is discovered in Ltincastcr (.-ount}'. Pa., and the control of this property was also olitained ]jv Mr. Tyson. It was afterwards developed into the famous Wood mine, which has produced aliout '.:)5,0(I0 tons of chromite. Chromite mining in Maryland and Pemisvl- vania continued for a great many j^ears until many of the deposits or pockets of chromite were worked out. About the time the ore began to grow scarce in these states, it was disco\-ered in California, and for a few years a number of thou.sands of tons were shipped to Baltimore. When, however, the importation of chrome ore began, aliout 1884, the chrome mining industrv in the United States began to decline. There are known deposits of this mineral in quantity in California and North Carolina, and ]iro1ta))ly deposits exist in Penn- sylvania and Maryhuid; liut, on account of the low price at which the foreign ore can lie landed at Baltimore, but a small portion of tluit used in the United States is mined here. New uses for chromium and the construc- tion of railroads through some of the chrome fields will 'Transactions of the American Institute ol Miuini; Euyineers Vol -XXV, i)au;e 487. " ' ' 96(1 MINES AND UUARRIKS. undoubtedly cause sin increase in this industry during the next few }'ears. The uses of chroniite, at present tlie only source of chromiiun, can })e readily divided into three heads: 1. As a mineral: In the manufacture of bricks as hearth lining-s foi' basic, open-hearth furnaces, and for water-jacket furnaces in copper smelting. For these purposes ores carrj'ing as low as -io per cent of chronii(' oxide can be used. It is also probaiile that chromite can be used to advantage in other furnaces, especially where it is desira])le to use fluorspar as a flux. 2. In chromium alloys: Chroniite is used to a con- siderable extent in the preparation of a ferro-chromium allo}-. The preparation of this alloy, which is used in the manufacture of armor plates and armor-platc- piercing projectiles, has 1)ecome a very important in- dustry. The ferro-nickcl alloy is also used in the manufacture of armor plate. It is generally made by the addition of these two alloys of iron to molten steid before it is cast into the ingot: they produce a more or less homogeneous tri]")le alloy. 3. In chromium salts: The first use of chromite was in the preparation 'of the salts, chromate and bichro- mate of potash, used in d^-eing. tanning, and in the manufacture of pigments; this continues to be its chief use. It was about Isoo that the value of these salts as pigments was discovered, but it was not until the discovery of deposits of chromiti' that they were used commercially. .Some chromium salts are also used for medicinal purposes. Nlf'KKL AND COBALT. Nickel and cobalt mining in the Ignited States began probably in 1863 witli the opening of the Ga)) mine, in Lancaster county. Pa. This mine was worked ahuost contiiuK)Usly and very extensively from bSB;3 until lS8ti, and was the only nickel mine then worked on the Amei'ican continent. Witli tln' discovery, however, of the nickel deposits in the Sndbui-y district, Ontario, Canada, and the moderate prices which prevailed foi- nickel, work at tliis (iap mine ])egan to decrease, and about 1M>1 ceased altogether. It is \-ei'y ])i'obable that tliere are still good deposits of nickel ore in (|uantity in this mine and that in the near future it will again become a producer. Since Is'.il most of the nickel and colialt produced in the United States has been at Mine Laujotte, Mo., where it has been obtained as a by- profluct in lead mining. Attempts werii made to mine nickel in North (Carolina about ISilo, and although the mineral genthite, a nickel silicate, was found in some (|uantity at a nundier of ])laces, there was only one place — near A\'ebstei-. dackson coiuity — that gave any indication whatever of containing it in commei-cial ([uantity. Considerable work was rlone, but in bS'.tl the mine was closed and remained so until 11H)2, when tlie sliafts and drifts wei'e reopen(>d and sex'eral car- loads of ore were slii|)])efl for experimental purposes. There has also been some development of nickel depos- its in Oregon and Idaho, and a few tons of ore have been shipped for experimental purposes, but none of the mines can be called producers. The first general use of nickel commercial!}' was probably in the manufacture of ( xerman silver or albata, an alloy of zinc, copper, and nickel. Articles made of iron and plated with nickel have to some extent replaced those madt' of German silver. Another of the earlier uses of nickel was for coinage, which is yet carried on (juite extensively by the United States and many of the European countrit's. With the introduction of nickel in the manufacture of a special stf'el the demand for it has largely increased, so that this use of the metal has become the most important. Large quantities of nickel steel are used in the niiinufacture of armor plates, tur- rets, })ropeller shafts, crank shafts, etc. Another use that has received favorable consideration is in the man- ufacture of nickel-steel rails, which were first used by the Penn.sylvania Kaih'oad Company, and evidently gave entire satisfaction. Cobalt is put on the market as the oxide and used almost entirely for coloring glass, porcelain, and simi- lar substances. TUNCJSTEN A\T) MOL'^'BDEN'UM. The mining of tungsten and molybdenum ores in the United States has become an established industiy within the past few years only- Tungsten oi'es were mined in Coloi'ado and Connecticut, and molybdenum ores in Washington. Until lately the uses of these metals were few, requir- ing a coiuparatively small amount of their salts to sat- isfy the demand. The salts of tungsten were used as a mordant in dyeing and ]n-inting and as fireproof mate- rial for wearing a]ipaicl, -while the principal use of molybdenum was in the manufacture of annnonium molybdate. used by chennsts in the determination of ])liosph(irie acid. A small amount oi moh-bdenum salts is used ill the preparation of blue carmine or molyb- denum blue in the cohn-ing of porcelain. The use, liowe\er, of these two metals in the preparation of ferro alloys has led to an increased demand, especially for tungsten, which, when added to steel, increases its liardness and toughness, and is believed hv somt' to make it superior for certain purposes to anv other manufactured. Tungsten steid is also used in the man- ufacture of tool ste(d, spring steel, anfl sdunding plates and wires for pianos, whei'e hardness and streno-th are especially desired. Molybdemun steel, the beneficial properties uf which are similar to those of tungsten, is beginning to be used, but in nuich smaller (piantity. KUTILK. The only titanium nunei-al mined for coumiercial purposes is riitile, a titanium oxide. Titanium was for- nierl\- considered one of the very rare metals, but it has STEEL HARDENING METALS. y(i7 now been proved to be one of the commoner elements and is very widely distributed. In the future, liesides rutile, the ehi(>f eonunereial souree of titanium will be the mineral meiiaccanite (ilmeTiite), a titanium iron oxide. Kutile has l)een i)rodueed at Roseland, Nelson county, Va., anil in Chester county. Pa. Only a small quantity is required to satisfy the demand, and the prod- uct does not amount to nuich over l()(i tons of the crude ore per year. The uses of rutile are principally in the ceramic in- dustry for coloring- porcelain and in the manufacture of artificial teeth. The titanium oxide will, under fa- vorable conditioTis. impart a tine yellow color to the porcelain, and it is also capable of beino- used with other substances to produce secondary colors. The amount of titanium oxide used in the manufacture of ai'tihcial teeth is from ti\'e-tenths of 1 per cent to 2 per cent of the total materials used in making- thenj. At the present time no titiinium is used comnierciall}'. as far as known, in the manufacture of titanium steel, although irons have been made containing- a considera- ble percentage of titanium, the result of using ores for their iron contents rather than their titanium. Con- siderable work has been done, however, experimentally in regard to the use and value of titanium steel and with a great deal of success. It is probable that the intro- duction of this kind of steel into the general market is not far distant. Its properties of special interest are elasticity, and greater elongation and ductility than ordinary carbon steel. URANIUM AND A'ANADIUM. The production of uranium and \-anadium ores dur- ing 19(.ii! was ail in Colorado. The_v have been mined in small quantities for a great many years, some of the salts of uranium being used to produce a pure l)lack glaze on porcelain, while other salts are used in the decoration of glass and china ware, giving permanent cohn-s. Vanadium salts are used in the coloring of glass, but principally in the preparation of vanadic acid, as a mordant, for aniline black in dyeing. The use of uranium and vanadium in the manufacture of special steels is still in the experimental stage, but enough has been done to prove that they increase tensile strength.

ASBESTOS (969) ASBESTOS. ]?y Jose I'll IIydk Pkatt. Two distinct minerals are included in tliese statistics as asbestos, one heiny a \-ariety of aniphihole and the otlier tlie tihrous variety of serpentine known as chrvs- otile. It is the latter that is the more valual)le and for whicli there is the greater demand. In the United States, however, it is. thus far. principally the amphibole variety that has l.)een mined. The low value of this mineral and the uncertain demand have caused a wide variation in production. The tirst census statistics for asbestos were reported in 18So. when, among minor minerals in the Report on Mining Industries, 7 mines were shown to have been operated — 4 in Maryland and 1 each in Georgia, New York, and South Carolina. The numl)er of employees reported was 17, who received ^1, •!:()(• in wages. There was no cost of supplies or materials given. The production of asbestos was 15n tons, valued at §4,312. The company operating in Georgia was incorporated with a capital of $10,0(J(». At the Eleventh Census there was no record of the number of mines or establishments. The capital rep- resented was stated to be $l:2,6ori:ifr(J coirijiuiiies. — Of the 4 operators in the asbestos industry, 3 were incorjjorated companies, 1 each of these being located in Connecti- cut, Georgia, and Virginia, In Table 2 are shown the details of their capital stock. Table 2. — ('apitiilizdt'nui of iiicoriior received from $1 to $1.24 pel' day: 1 received from $1.25 to $!.-(■'.» per day; and 3 received from $1.5() to $1.74 per day. There were 2 machinists or blacksmiths, 1 of whom received the highest rate paid, which was from $2.50 to $2.74 per day. There were 2 firemen, each of whom received from SI to $1.24 per day. One other wage- earner, who did miscellaneous work, received from $1.5(» to $1.74 per day. The prevailing rate of pay was from $1 to $1.24, lij having received this rate. These comparati\'ely low rates of pay are due to the fact that most of the miners were employed in the South, where the rates of pay are much lower than either in the North or the West. HiippHeH. iiKifi-rialH, mid iinsceUinieniis expenxes. — The principal item of expense, next to that for wages, was for supplies aiirl materials, foi' which $8,^33 was reported as having been expended. The miscellaneous expenses of $1,758 were incurred for rent of office, taxes, insurance, and other sundi'ies. Thus, the total cost, including wages, salaries, supplies, materials, and miscellaneous expenses, was $20,869. Mecliiiiiiciil piiir, r. -Steam engines with a total of 105 horsepower were used in producing the asbestos, this power being reported by 2 establishments — 1 in Georgia anrl I in Virginia. I'riid iii-fiiiii. - The total production of asljestos in the United Stall's for' VMVl was 2,505 short tons, valued at $46,2(J0. This production of asbestos is the largest I'e- ported during the period beginning with 1880, in which year the statistics for this mineral were first obtained. Of this production, however, 1,50(» tons represents the rock just as mined. The statistics do not, therefore, represent the total value of the asbestos as it is put upon the mai'ket. In some instances the asbestos was crushed, separated, and otherwise prepared at the mines. As in such cases the mining and the processes to which the mineral is subjected were conducted under the same management and with the same capital, it is impracti- cable to separate the statistics. The United States Geological Survey has published annual statistics of the ([uantity and value of asbestos, and these are shown in Table 3, for the years from 1889 to 1902, inclusive. Table :i.—Pro IfiOi. [United States Geological Survey, "MuaeralKesourcesoftheUnitedStates," 1902.1 YEAR. Quantity (short tons). Value.

This is due. as stated above, to the uncertainty of the demand for this variety of asbestos. The highest prices were recei\ed for as- bestos during the years from 1889 to 1893, when the values varied from $50 to $64.23 per ton. These high prices were undoubtedly due to the fact that certain manufacturers recpiired only a few tons of asbestos, and in order to obtain these small ([uantities they were obliged to pay this increase in price. The total quan- tity of asbestos jiroduced in the United States since 1880 amounts to only 10,917 tons, which would make an average jiroduction of 474 tons per year. The greatest (|uantity jiroduced in one year was l,2oo tons in 1882, and the next greatest, 1.054'tons, in 1900. The aver- age value varied froni $64.23 in 1890 to $11.12 in l,sit7. In 1894 there was a decided drop in the value of amphi- bole asbestos, from $50 to $13.73, and since that time the average has not exceeded $18.07. In L902 the values varied from $16 to $40 per ton, the latter price hav- ing been received for 5 tons of chrysotile asbestos which were obtained as a by-product in talc minino-.

DESCRIPTIVE. As is seen from the preceding- tables and text, the asbestos mining industry in the United States is very small, and there is but little chance of its increasing, unless large deposits of the chrysotile asbestos are dis- covered and developed. There are very large deposits of amphibole asbestos, but, as already stated, there is not sufficient demand for this variety to create a large industry. Although in many respects the two varieties are sim- ilar in physical properties, there is a wide variation in strength of tiber, the chrysotile variety being superior in both strength and elasticity to any amphibole asbes- tos, and for this reason capable of being- used for manj^ purposes for -R^hich tlie latter can not lie adapted. With respect to their heat-resisting properties, they are about equal, so that when asbestos is to be used as an ingredient in fireproof paint, wall plaster, as boiler coverings, as piirkiiig, in the manufa(-ture of hreproof safes, and for nearly all purposes in which noncon- ductivity of heat and not strength of tiber is the important factor, the amphibole variety c:m be used to as good ad\antage as the chrysotile. For these pur- poses there is probably but little chrysotile asbestos used, except what is known as asbestic or the waste portions. There are, however, a numbei' of other min- erals, such as infusorial earth, tripoli, talc, and mica, that are strong- competitors of the amphibole asbestos. On the other hand, where strength of fiber is essen- tial as well as nonconductiA'ity of heat, as in the man- ufacture of cloth, rope, felt lioards, tubes, wa.shers, and blocks of various shapes, it is only the chrysotile vari- ety that can be used. The fibers of chry.sotile are sel- dom over 2i inches long, and are usualh' from one-half to 1^ inches in length. The fibers of the amphibole variety, however, occur up to 3 feet in length, and when this asbestos is fairl}' free from grit, it appears like a verjT attractive j^roposition. In a number of cases deposits of amphibole asbestos haA'e been developed in attempts to compete with chrysotile, Init in each case the effort has resulted in failure. It is interesting to note the variation in the value of these two varieties of asbestos; for the amphibole vari- ety' there is usually simply the one fiat rate, wliich has varied, since 1894, from ¥11.12 to flS.tiT per ton. On the other hand, the chrysotile asbestos varies in price according to the different grades as follows: Per ton. Nil. 1 a.sbestos S150 to S2.50 N(i. 2 (white) asbestos 75 to 125 X( ). .3 (red ) asl )estoe 50 to 75 Mill filler, < a- paper stock 20 to 40 Asbestic 1 to 3 The mill fiber, or paper stock, is the minute fibers of asbestos which have become broken and are not capal)le of })eing used for weaving, and the asbestic is the final waste material, wiiich contains a small amount of minute fibers and a considerable amount of the crushed serpen- tine rock. Occurrence. — Since 1S80 asbestos properties have been prospected and developed in the United States in Arizona, California, Ceorgia, ]Marvland. ^Massachusetts. Michigan, New Jersey, New York, Pennsylvania, South Carolina. Vermont, Virginia, and "Wisconsin. Although a consideral)le search has been made for asbestos depos- its in this country, it has resulted thus far only in the discovery of producing deposits of the amphibole variety. At the present time the deposits of amphibole asbes- tos that are being Avorked or developed to any extent are as follows: About 3 miles from the railroad station at IS'ew Hartford, Conn., a deposit of this asbestos occurs in a 974 MINKS AND QUARRIES. ledge that outcrops stronglj' for a distance of about 75t» feet in lengtii, with a Avidth of yt» feet. It has been opened in a number of places to a depth of 4.-) feet. A plant for crushing- and preparing this material for the market was being erected in 11)02. At Sal mountain, 12 miles northwest of Clarksville, Ga., are located the largest developed asbestos deposits in the United States. In the northeast corner of Rabun county, Ga. , and about Ij miles from Russell, S. C, deposits of amphi- bole asbestos occur. In Virginia, about 14 miles south of Bedford C'ity, a deposit of amphibole asbestos occurs in seams and veins varying from S to 50 inches in thickness. In Wisconsin, near Stevens Point, Wood county, a deposit of this asbestos has lieen developed, although no asbestos was produced during 1902. ^lany other deposits of amphibole asbestos are known to exist in the United States, but unless they are very favorably located for mining, and have good transpor- tation facilities, it is practically impossible to work them on a protitable basis. Chrysotile asbestos has been found sparingly asso- ciated with many of the outcrops of Ijasic magnesian rocks that extend northeasterly from Alabama across Georgia, South Carolina, North Carolina, Virginia, Maryland, Pennsylvania, the New England states, and into Canada. These rocks are more or less altered to secondary serpentine, and in the more northern sections different areas are often completely converted to this secondary rock, as those of Pennsyl\-ania, ^Maryland. Vermont, and Quebec province in Canada, while in Noi'th Carolina, Georgia, and Alabama there ar(> but very few areas that have l)een altered to this extent. As would be expected, it is only in those areas in which the rocks have been completely changed to serpentine that the chrysotile asbestos occurs in commercial (juan- tity. Although only the very small amount of this \-ariet3' of asbestos obtained from Massachusetts was produced from a mine already in operation, yet a great deal of work was done on deposits of this A-ariety in Vermont and Wyoming, with a smaller anioimt of worlv on deposits in California, ^Michigan, and Noi'th Carolina. The Vermont deposits are located in th(» north cen- tral part of the state, in the town of Ed(>n, Lamoille countv, anfl in the adjacent t(l^vn cif Lowell, Oi'leans county. The ^V\•()millg deposits, wliidi are located in the vicinit\' of Casjjer. Natrc.ina county, have been priitty thorough!}' de\'eloped, but thus fai- operations ha\e not been sufficiently arlvanced for the marketing of the product. The dep(jsits of California thus far developed are in Riverside county. The other deposits in this state and those in North Carolina, have been developed little more than to prove that the chrysotile asbestos is to be found. The basic magnesian rocks of the Pacific slope, in California, Oregon, and Washington, have in many instances been entirely converted to secondary serpen- tine, and are promising tields for investigation. It is possible that when they are thoroughly prospected they will be found to contain deyjosits of the chrysotile asbes- tos capable of profitable operation.

The large increase in value of product from $10,000 in 1860 to *!^150,()00 in 18T(.» was due to the dis- covery in West Virginia of a vein of grahamite, which was soon exhausted. A revival of the industry took place between 1880 and 1889. The increase in wages from 1889 to 1902 was Sl(i,067, or 2.5.3 per cent, and the increase in value of product was $65,191, or 38 per cent. The 24 mines reported for the industry in 1902 were controlled by 19 incorporated companies. 3 indi- vidual proprietors, and 2 firms.

Pr(idnctii)ii. — The United States Geologitnil Snrve3' has pnlilished annual statistics of the production of asphaltum since 1SS2, but these are not coniparahle with Census statistics, for the reason that after the year 1891 they include maltha, or brea, and the asphal- tum by-products of petroleum refineries. During 11)02 the quantity of by-product asphaltum produced by oil retineries in California and Texas, and sold aiul used in the trade as asphaltum, amounted to 2o,s2() short tons, A-alued at $303,24:'.t.' According- to the reports received for r.H»2, the average price of asphaltum was $3.57 per ton. The range was from §1.50 to $50, the former for less than 100 tons mined in Indian Territory, and shipped in the crude state, and the latter for less than 1,000 tons of elaterite mastic mined in I'tah, f. o. b. at the mines. Most of the imported asphalttmi comes from the Island of Trinidad, British West Indies.

The detailed statistics of the industry in the United States for 1902 are shown in Table 5. DESCRIPTIVE. Asphaltum is the name applied to ditferent forms of. bitumen. Its composition varies, and it is known by many other names, bestowed on account of some special characteristic resulting from its composition or the locality from whence it has been obtained. The most common of these names are: Natural mineral pitch, Jews' pitch, Trinidad asphalt, Cuban asphalt. Dead sea bitumen, numjak, maltha, lirea. chupapote, elaterite, wurtzilite, nigrite, gilsonite, grahainite, and uintaite. Asphaltum has been an article of commerce from re- mote anti(|iiity, the supply having been obtained from the deposits near the Dead Sea, where the material tloat(Hl on the surface or was washed ashore by the waves, the product ):»eing known to the Arabs by the name of Htijiir ]Mousa, or INIoses's stone. In Germany asphaltum was known as earlv tis 1620 under the name of "harzerde"' (pitch earth), which was described in 1(192 by Doctor Amiest as asphaltum. 980 MINES AND QUARRIES. Bituminous lime.stone is mentioned hy Doctor Krynis in several puljlieations prior to 17'2l. The deposits at Se^'ssel, France, were discovered in ISO^, and the asphaltum interests of France and Switzerland were united in 1832 by Count de Sassenay. PJiyxlcal tnitl clu'iiilivl eluivddi'r'ixticx. — Asphaltum ranges in form from the li((uid maltha to the hard, solid glance pitch, which graduidly merges into asphal- tic coal. The specific gravity of pure asphaltum ranges from 1 to l.H.and the hardness from 2 too. The solid varieties have a black or dark-Drown color and a peculiar characteristic pitch}- odor when rub))ed. Asphaltum breaks with a more or less splintery frac- ture and does not soil the lingers. It is very brittle at low temperatures, but upon being warmed, although it remains sutKciently hard to lie broken l)y a sharp lilow, at the .same time it yields to a steady pressure or tread. Asphaltums differ much in their properties, and all do not possess the binding power so necessary for a lasting- pavement; they shade by insensible gradations into brittle asphaltic coals. The melting point of asphaltum is usually low. It is \ery inflammable, burns with a yellow, smoky tiiame, and when pure leaves very little if any residue. It is insoluble in water, slightly soluble in alcohol and fixed and essential oils, and readily soluble for the greater part in ether, oil of turpentine, naphtha, and carbon l)isulphide. With benzole it forms a solu- tion of an intense black color, used as a varnish. When subjected to destructiA'e distillation, asphaltum is decom- posed into a distillate of oils and a tarry residue which becomes solid when cold. The chemical composition of asphaltum is so complex that elementary analyses throw little light on the sul)- ject. It still remains an open ([uestion whethei- impor- tant groups of definite and characteristic hydrocai'bons can be separated and recognized. Many chemical analyses of asphaltum from various localities have been published from time to time which, however, are of scientific \'alue only. Of these analyses the following are characteristic: Aiwbjttex of purr fift/iliiiltniii, r.rrliixirr of rarllni iiinllr ■meclixi'iiicul impiirUiex. "nil iithri- CHEMrST. • Plafi-.

The first of these is a solubility test of th(> sample dried at 21'2''^ F. in various solvents, as carbon bi.sulphide, alcohol, turpentine, ether, petroleum, naphtha, etc. Distillation is often used and the ios.ses at various tem- peratures are recorded. The quantity and qualitv of mechanical impurities (water, clay, earthy matter) con- tained in the .sample are also determined; finally, the best test of its applicability for pavement purposes is its viscosity at various tenijieratures. In some cases the value of an asphaltum for use in pavement con- struction is det(M-mined by an actual trial. The substances clas.sed as bitumens are hydrocarbon compounds, the more important of which, arranged in the order of their specific gravities at TO" F., are divided into six groups: 1. Natural "an. • - r 2. Natural iiaplitlia. .1. Petriileuni, i>r natural oil. 4. Maltha, iir.suft, sticky bitumen. .'i. Asi>lialtuni, or stiff, sticky bitumen. 0. (flanre i)itcli, or dry, brittle liitunien I often called jrilsonite). In addition to the substances comprising tlie above list, there are other bitumens of chemical interest only, which possess no commercial value. In commerce there are four cliief classes into which asphaltum is divided: (1) Th(> natural liiiuid form, called liciuid asphaltimi or maltha; (2) asphaltum mixed with more or less vegetal)le and earthy matter, which yields, by the removal of the mechanically contained imptiri- ties, the product called hard, retined, o.' gum asphal- tum; (3) asphaltum contained in sand or sandstone, called bituminous sandstone; (4) asphaltum contain(>d in lime- stone, called bituminous limestone. In addition to the natural products given in the above list mention should be madi^ of "by-produi't asphal- tum," which is obtained in th(> refining of crude petro- leum having an asphaltic base to yield commercial illu- minating luid lubricating oils. There is no strict line of demarcation between oils classed as petroleum oils and those considered as asphaltum oils. The term bituminous rock is applied to botlt sand- stones and lini(>stoncs impregnated with asphaltum. Bituminous rock is sold and shipped without previous refining, and is consumed chiefly for street pavements, being generally mixed with other ingredients at the place of use. An inconsiderable proportion, however, is treated for its a.sphaltic content, the jiroduct being sold as refined or gum asphaltum. Asphaltic or bituminous limestone is a natural com- pound of asphaltum and limestone, at times contaiuim>-.

'J'ho quantity of asphal- tum present varies in ditierent deposits, and even in diflerent portions of the same deposit, up to i)0 per ccMit. The grain of asphaltie limestone is extremely tine, and under the microscope each grain appears completely coated with asyjiialtum. It is this property wliich ren- ders the natural product of greater \alue than an arti- ficial mixture of asphaltum, tine sand, and puhcrized limestone.

The lower limit of the as- phtdtic sand has been foinid at a ts. A property 1 miles northeast of Kussellville, Logan county, has been developed quite extensively, the quarrv face showing a 17-foot asphaltum ledge. The plant of this company includes a 250-ton gyratory crusher and plain 14 by 18 inch rolls. Quarries, mill, and tipple are connected b_v li miles of narrow gauge track, and at the end of the year the rolling stock equipment con- sisted of 1:5 cars. At Louisville, the operating com- pany has installed a plant for mixing and preparing asphaltum for street paving work, which has a daily capacity of preparing material to co\'er an area of 18,000 square feet. An asphaltum company near (iarfield, Breckinridge county, has a 100-ton pbmt. The asphaltic rcick is broken in two sets of beaters re^'olving about hori- zontal shafts, the first making (1(»<) and the second 1.200 revolutions per minute. The I'oarsely broken material from the first beater is passed to a 2 -inch screen, the oversize being returned for a second treat- ment. The matei'ial ))assing through is treated in the second beater, which delivers to a screen. Material ex- ceeding one-sixteenth of an inch in size is I'eturned to the second beater f(n- another treatment. Tr.riix. — There has been comparatix'elj' no apjoreciable production of asphaltum in this state in I'eccnt years. That reported in 1002 was liquid asphaltum. UtiiJi. — In recent vears a small (luantity of asphaltic limestone has been produced from deposits in the. east- ern part of the state, nearly the entire output being consumed in the local marlcets. The chief asphaltum product, however, is gilsonite (also called grahamite), which is mined about (io miles from Vernal, Uinta county. Gilsonite is a very high grade material, of especial value for manufacture into varnishes, lacquers, paints, and similar products. On account of the high price it conunands. the product can stand a long- distance freight rate to chemical works. Zhes. — The principal use for asphaltum is in the con- struction of pavements. In addition, a considerable quantity is ronsumed for the manufacture of special varnishes; for waterproofing buildings and other objects as a protection against dampness; for coating vessels, as a protection against the teredo, or ship-boring worm; as an enamel for iron objects; for roofing purjjoses in the form of asphaltum or tar paper; for electric current insulation; and as an ingredient of cement. Asphaltum sidewalks were fii'st used in Paris in 1838, and to-day they extend to a distance exceeding in the aggregate l,2(Hi miles. The introduction of asphaltum pavements in the principal cities of the world is given by.T. W. Howard' in the following chronological order: Paris, 1851; London, 1869; Budapest, 1871: Dresden, 1872; Hamburg, 1872; Berlin. 1873; followed shortly afterwards by Brussels, Geneva, Leipzig, Frankfort, and others. Li the United States a so-called "tar- poultice pavement," composed of coal or gas tar, sand, etc.. was laid in several cities during the period from 187(1 to 1873, and in 1871 to 1873 successful expermients were carried out with an artificial asphaltic sandstone pavement in New York, N. Y., and in Newark, N. J. In ls78 a pavement composed of Trinidad asphaltum, sand, and powdered limestone was successfully intro- duced in Washington, D. C. and has since been the standard jjavement of that city. At the present time more than a hundr(>d of the ]irincipal cities of the United States have adopted some form of asphaltum pavement. In making asphaltum pavement the general procedure is to grade the street to be pa\'ed, roll it with a steam 'The Minenil Industry, Vol. II, page 51, et seq. 984 MINES AND QUARRIP:S. roller, and then eover it with a layer cit' cenient coiirretc 5 or 6 inehes thick; or in case the street is macadam- ized or paved with stone blocks, the concrete is unneces- sar}'. In the latter cases a thin layer of asphaltum con- crete from 1 to 1.0 inches thick is laid directly upon the old surface. The foundation having been thus pre- pared, the asphaltum paving- nijxture, called the " wear- ing surface," is then spread over it with heated rakes to the desired thickness, which \'aries from 1.5 to 3.5 inches, depending upon the traffic to pass over it. The ordinary Trinidad asphaltum paving mixture is made by adding and thoroughly mixing with hot rehned asphalt about 15 per cent of its weight of residuum oil, the mixture serving to cement together the sand and powdered limestone which enter into the paving mix- ture. The proportions of the ingredients vary accord- ing to their physical and chemical quality, as well as to the climate in which the pavement is to i)e used, hot climates requiring less cement than cold. A typical pavement is composed of from 15 to IS per cent of asphaltic cement, from 7(i to 83 per cent of sand, and from 5 to 15 per cent of limestone. For use in making pavements, the mined asphaltic limestone is crushed into pieces not exceeding 3 inches in diameter, and then reduced to about Id-mesh size in a ball or centrifugal pulverizer. The hue material is heated to 275- F. in heaters, spread over the prepared roadbed, and compressed b}- heated ranuiK'rs. or other- wise, until it is of a thickness of from 2 to 3.5 inches. This form of pavement is not popular in places subject to fogs, rains, and low temperatures, for the reason that it becomes polished and slippery when wet, or dry in cold weather. In Paris and Berlin large supplies of sand are kept near the streets paved with asphaltic limestone for use during fog, slight rain, or snow. Pavements made with Trinidad or other asplialtum in which sand, in pi'oportions uj) to 80 per cent, is the chief ingredient, do not become siippei'v except wdien covered with ice; the sand makes tiiem gritty and not susceptible to polish. For the manufacture (jf lilack \arnish, used diietly for coating ironwork, pure uspliaituui is disso]\ed in benzole or iiciuids containing benzole. The asphaltum from Syria is used foi' this pur|)ose. V>\ c(j\'ering lu>t iron with asphaltum \'arnish tlic \"olatilr ingi'cdicnts of the latter are driven off, leaving a residual costing in the form of a smooth and polished enanicl. For insulating and cementing purposes asphaltum forms a very im])ortant ingredient on account of its wonderfully adhesi\'e quality. For waterproofing foundations of brick or stone, asphaltum is dissolved in petroleum and laid in the form of a cement or mortar, forming a very durable -waterproof c( >ati ng. For making cement, petroleum residue is added to asphaltum in order to render it plastic, and from 5 to 1(1 per cent of sharp sand is mixed with it, according to tiie purpose for which it is to be used. For rooting purposes asphaltum is used to a \ery large extent in admixture with coal tar. pitch, or petroleum residue; the 'material being used to saturate two or thi-ee thicknesses of felt, which are finally com- pressed into one compact sheet. The tar or rooting felt is held in place ))y nails driven through tin disks, and the whole completely covered with cement similar in composition to that used in making the felt; while this is still soft a covering of sharj) sand, or screened gravel, is spread ovei' the surface, forming a tight roof of great durability. Axplidltiiin rcfn'iiKj. — There are various methods used for the retining of asphaltum. depending on the nature of the crude material and the use to which it is to be applied. In general, with high grade material, the treatment has for its object the removal of water, vola- tile hydrocarbons, and mechanically suspended uiineral and vegetable matter, but with asphaltums to be used in pavement construction it is essential to allow the mineral matter to remain in the product, for the reason that the asphaltum in this case is to serve solelv as a binding and waterproofing material. In fact, asphaltic rock of the propei- composition is not refined before use, but mendy crushed, heated, and laid, in j)lace. The simplest method of extracting asphaltum from its compounds is l)y boiling in water, which causes the lighter asphaltum to i-ise to the surface, from whence it can be easily removed. Conunon salt or calcium chloride may be substituted for water in the ti-eatment of material requiring a higher temperature or a heavier supporting li(|uid. In other cases asphaltuui is extracted by means of a solvent, such as carbon bisulphide or naphtha, and obtained fi'om the solution by heating in stills, which causes the volatile solvent to ))e distilled for re[)eatpd use and leaves the li(|uid asphaltum residue in a practically pui'c condition.

Ey Joseph Stkuthers, Ph. D. While the produetioii of bauxite in the United States on a commercial scale dates from the opening of the deposits in the state of Georgia during- 1S.S9, the min- eral does not appear to have been produced in sufficient quantities to be included in the reports of the Eleventh Census. This report, therefore, contains the I'esults of the first census of the mining of bauxite in the United States. Table 1 is a sunnnary of the statistics for 19(12. Table 1. — Siinnnary: 19(iJ.

The entire number was controlled l)y 7 oper- atoi's, of whom .5 were incorporated companies and 2 individual owners. There were 31 mines operated by 3 incorporated companies, 1 company controlling 19, another 10, and another ,5 mines. There were 2 com- panies and 2 indi\'idual owners operating 1 mine each. This centralization of the industry makes it impossible to publish the .statistics for the different states without disclosing the operations of individual companies; there- fore, only the totals for the United States are presented. One mine in Arkansas was reported idle in 1902. Capital nfock of incorporated companii-x. — A consid- erable portion of the total production of bauxite was mined by establishments that were engaged in mining- operations as incidental to the manufacture of alumi- num, paint, and chemical products. The capitalization of these companies represents both their mining and manufacturing industries and, therefore, is not included in this report. Of the 5 incorporated companies, 3 reported that the}' were engaged primarily in mining. Their authorized capitalization consisted of 2,500 shares of common stock with a par value of $22.''i,O00. Of this amount, 1,730 shares, valued at $118,000, had been issued at the close of the year covered by this investiga- tion. No dividends appear to have been paid on this stock during the y(>ar. Employees and mu/i s. — The vai'iation in the number of wage-earners employed during the different seasons of the year and the speciffcd daily rates of pay are shown in Table 1. The height of activity in the industry appears to have been reached during the month of May, when an average of 168 wage-earners was reported. The smallest numl;)er, 132, was given for the month of December. The slight variation in the number em- ployed during the entire year indicates a unifoi-ni production. The mining of bauxite requires no particular skill on the part of the miner, and the rates of pay should not be compared with those reported for miner.s of other minerals where skill and experience are necessary. Of the total number of wage-earners, 77, or 51.3 per cent, were classed as miners. Of this number the wages for 64 ranged from $1 to $1.21 i^er day. The rates for "all other wage-earners," which includes those engaged in assorting, grading, handling, loading, and hauling the ore and in miscellaneous work in connection with the mining or quarrying of bauxite, were considerablv higher than the rates reported for miners. Of the 53 reported for this class, 10 received from $1.50 to SI. 71 per day. The rate of pay at which the greatest number of wage-earners was employed is from §1 to §1.21 per day, 69 having been paid at this rate. One hundred and thirty-four, or 89.3 per cent of all wage-earners, received from $1 to $1.71 per day. This uniformity in the rates of pay is due largely to the fact that 69 wage- earners, or 16 per cent of the total number, were reported l:)y 2 operators working on a large scale. The extraction of bauxite is from open cuts, no tun- neling l)eing required, and all of the employees, there- fore, were reported as engaged above ground. The 150 wage-earners give an average of 3.95 to each mine, but it is probalile that all of the mines were not operated during the entire year. In addition to these wage-earn- ers, 10 others were reported as employed by contractors to whom the sum of $500 was paid. (989) 990 MINES AND QUARRIP]S.

The total primary power amounted to G-i-t horsepower, of which 575 horsepower was supplied liy 19 steam engines and J:l» horsepower liv ^ gas or gasoline engines. Tliere were also 4 electric motors with 64 horsepower Pnidiictuni. — The total production for the calendar year 1002, as shown by Table 1, was 29,222 long tons, valued at $128,206. The ITnited States Geological Survey has published annual statistics concerning the quantity and value of bauxite. Table 2 shows the totals foi' each year since 1889. Since the economic impor- tance of bauxite is due almost exclusively to its use in the manufacture of the metal aluminum, aluminum sulphate, conunon alum, and artificial emery, this table has been prepared so as to show the available figures for the manufacture of these substances. Statistics for the production of sodium aluminate and other salts that contain aluminum can not be secured.

BAUXITE. y'.)i A detailed summary showing tlie statistics for tlie production of bauxite during- 1902 is given in Table 4. DESCRIPTIVE. Occurrence. — The mineral bauxite was first di.scox- ered in the year 1821 near Baux, France, i)y the well- known French chemist, Berthier. He attempted to utilize it in the manufacture of alum, but, because of the large proportion of iron oxide it contained, h(> was unsuccessful. Later a deposit of the white variety, of greater puritj' than that of Baux, wa.s discovered at Herault, also in France. The mineral did not, however, become of commercial importance until IfSfiS or 18()9, Avhen Sainte-Claire Deville, a French scientist, in the course of his experiments in the manufacture of alum- inum, discovered the value of bauxite as an ore of this metal. In 18S1 occurred the first ret'orded discovery of bauxite in the United States. The find was made by Edward Nichols, at Hermitage, Floyd county, Ga. Afterwards deposits were found in Polk, Bartow, Cxordon, and Chattooga counties. In l8iU R. S. Perry reported the discovery of the mineral in Calhoun county, Ala., although it had previously been found in that state in Cherokee county, where it had been known as iron-ore blossom and as Clinton fossiliferous iron ore. Other deposits were afterwards found in Cleliurne county. In isyl, too, the mineral was re- ported by the Arkansas geologit-al surA-ey as having ))een found in Saline and Pulaski counties of that state. Other deposits have been found, notably in North Carolina, South Carolina, and New jNIexico, but they are too limited in extent, and are too far from transportation facilities, or, else contain too many im- purities to be of value commercially. Arranged in the order of their outputs, Georgia, Alabama, and Arkansas furnish the total production of the United States. The mining of the ore in this country is of compara- tively recent inception, and, quite naturally, it has not reached a high state of ethciency. The mines are irreg- ular holes dug in the hillsides, with deep, open drainage ditches leading from them. Below the surface the ore is sufficiently soft to be removed with pick and gad, which renders the extraction easy and lessens the t'ost of production. For a high grade product, however, the uneven quality of the ore makes necessary a sorting by hand or by screens. Screen sorting is generally pre- ferred to hand sorting when the character of the ore will admit of the use of the screen. During the sort- ing process, when clay is mixed with the Ijauxite, a common log washer is occasionally used to sepai'ate it. The sorted product is then dried in the air or in kilns or furnaces prior to its shipment to market. In this process very satisfactory results have recently been secured from the use of furnaces of the revolving cylindrical tj'pe. Refining was formerlv done ahuost exdusiveh' in Pennsylvania and New York, l)ut r(_'c('ntly new I'efining plants have been erected at Bauxite, in Saline county. Ark., and near East St. Louis, in St. Clair county. 111. These plants are equipped with niodei'n machinery, and hand labor has been supei-s(>,ded whei'cver prac- ticai)le. France produces three varieties of bauxite: The white of Herault; the pale of Baux and othci' localities of southern France; and the red, whidi contains a large proportion of iron oxide, and whicli is also found in several places in southern France. Of these, the white variet}^ is the purest, containing from 65 to 71 per cent of alumina, from 0.2.5 to 3 per cent of ferric oxide, and from 12 to 18 per cent of silica. Thus it is com- paratively free from iron oxide but contains a relatively large amount of silica. The most impure is the red variety, which contains from 5i per cent. ^ty2 mixp:s and quarries.

Tiirce varieties are distinguLshed, the inonohydrate (Al./).,, H.,0), the dihydrate (AL0,,.2H,,0). and the trihydrate (AljOjiSHjO). Apart from impurities the composition of these minerals varies from the monohydrate (dias- pore), which contains 85.12 per cent of ALO., and l-l-.S,s per cent of HjO, to the trihydrate (u'ihb.site), whicli contains 65.61 per cent of Al.,03 and Sl.SK per cent of H^O. More or less of the alumina in l)auxite is re- placed by iron or manganese oxides. Silica occurs in the mineral either free or in combination in clay. Minor impurities are compounds of phosphoric acid, suljihur, carbon dioxide, lime, and magnesia. In compo- sition the French mineral appears to correspond to the monohydrate while that of the United States approxi- mates the trihydrate. The comjjosition of bauxite can be determined only bj^ chemical analysis since it is not indicated by the physical properties of the mineral. According to Francis Laur.' the average composition is from 66 to 69 per cent of AL.Oj; 27 j^er cent of HJ), SiO^, and ¥S).,\ with from .3 to 4 per cent of TiO., and other impurities. In general the value of the ore is in direct proportion to the richness and purity of the alumina content. In ore of good ((ualitv the percent- age of alumina is high, while that of iron oxide and silica is low. Bauxite has a strong affinity fur water, which makes it necessary that the ore lie dried before shipment. For the manufacture of aluminum the pr(>s- ence of iron oxide and titanic oxide in the ore is not objectionable, but for making alum these insoluble ma- terials should not exceed 7 per cent, and the irnii oxide should be less than 2.75 per cent. Th(> ti-ih\'dratc. on account of its greater solubility, is best suiteil for the manufacture of alum, and for this pnrjiose the liaiixite of the United States is preferable to tliat of France. I']iyKi mineral. IMl'OKTANT I'ROiniCTS DKKINKl) FROM B.VUXITK. Four princi])al sul)stances are prepared from bauxite, \'iz. aluminum sulphate, alum, artificial emer\'. and aluminum hydroxide. From the last-named substance the metal aluminum is manufactured. Ahi,„nim„ .>.v//7;//,^/,>-Al.,(S0J,.l.sIL0.— This is a chemical salt technically known as "concentrated alum." It is ])repared by decomposing bau.vite with suliihuric acid. If the mineral is dissohcd directh' in the acid, j the pn)duct will contain a large ((uantity of iron, forni- I ing the so-called "aliimino-ferric cake," which is used for many purposes where iron and free acid are not objectionable, as in the precipitation of sewage and of waste licpiors from dyeworks. Pure aluminum sul- phate is now generally prepared by the Bayer process, which consists in adding powdered alumina to the solu- tion of sodium aluniinate, containing 1 part of Al^O., to I.S parts of Xa,,(). The reaction causes a crystalline [irecipitiite of alumininn hydroxide. The silica and the iron jiresent r<'mairi dissohed in the solution. The pr(>cipitated aluminum hydroxide is separated from the solution and is thoroughly washed and later di.s.solved in pure, hot, concentrat(^d sulphuric acid until the frothing cea.ses. The .solution is then transferred to shallow leaden ])ans and allowed to cool; thus the pure aluminum sulphate is .separated out in the form of M, .solid crystalline mass. Owing to its greater purity and greater strength, aluminum sulphate has largely replaced aJum in tile arts. Aluminum sulphate is exteiisi\('ly used as a mordant in dyeing: in prejxirincr BAUXITE. 998 size for paper; for making alum and aluminum salts (red liquor, etc.); in tawing skins; for precipitating sewage or coloring matter in water; and, in general, for all purposes in which alum was formerlj' used. Potassium alum — K^SO^, AL(S04)3,24H20. — This product is known also as "potash alum" and "common alum." The manufacture of alum from bauxite in- volves the preparation of a pure solution of aluminum sulphate to which is added the proper proportion of an alkali sulphate in order to foi'm the special alum desired. Thus potassium sulphate is used to form potassium alum and sodium sulphate for sodium alum. All alums crj-stallize from solutions perfectly, forming- very pure crystals even from impure solutions, and it is because of this pi-operty that the alums are so extensively used in the arts. The chief uses of com- mon alum are as a mordant in dyeing; in preparing size in paper making; in tawing skins; in making pig- ment lakes; for clarifying turbid liquors; for precipi- tating sewage waters; and for hardening plaster of Paris casts and other forms. For these uses, however, as mentioned above, aluminum sulphate is generallv preferred Itecause of its greater strength and solubility. Aliiiii in ii'iii Iiydrv.vide — A1„(0H)„. — The manufacture of aluminum hydroxide from bauxite is of great im- portance, because by a simple calcination it yields aluminum oxide (alumina), which is the chief crude material used for the manufacture of the metal alu- minum. In making aluminum hydroxide, bauxite is roasted, pulverized, and mixed with calcined soda ash in the proportion of 1 part of AljO, to 1.1 parts of Na^O, or greater if silica be present in the ore. The mixture is calcined at a white heat for three or four hours until all traces of carbon dioxide and water have been expelled. The calcined product is then ground and lixiviated with hot water; this process fields a solu- tion of sodium aluminate from which the aluminum hj'droxide is precipitated liy passing carbon dioxide gas through it. The impurities, silica and iron oxide, remain dissolved in the mother liquor. In order to avoid the costly and tedious chemical process of obtaining pure aluminum hydroxide, an electric furnace method has been recently patented by Mr. Charles M. Hall,' whereby the impurities in the bauxite, mainly iron oxide and silica, are removed, and the bauxite is thus purified for the aluminum reduction process. . The process of purifying the baux- ite consists in submitting it to a preliminary heating for some hours in the presence of carbon and metallic aluminum in an electric furnace, during which time the iron oxide and the sdica become reduced to metallic iron and silicon and combine with the aluminum to form a heavy alloy, which can be detached easily from the mass of purified bauxite after it has cooled. Artificial emery. — Within the past year or so a com- pany at Niagara Falls, N.

Mechanlval pomer. — Of the 23 mines or quarries, 8 employed power aggregating 740 horsepower, of which 155 horsepower was furnished b3' 4 steam engines, and 585 horsepower bj- 10 water wheels. The waterpower was reported for 5 mines in Maryland and 1 mine in Massachusetts. Production. — The total pi'oduction for the year 1902 was 36.365 short tons, valued at $144,2(.)9. This con- sisted of 20,295 tons of crude flint, valued at $35,046, an average of $1.73 per ton, and 16,070 tons of ground flint, valued at $109,163, an a\'erage of $6.79 per ton. Montana w'as the largest producer in quantity', with 10,640 short tons of crude flint, valued at $14,250. The production of Maryland and Penns3dvania was approx- imately the same, each 26.9 per cent of the total, liut Maryland produced 49.2 per cent of the ground flint, and Pennsylvania 34.5 per cent. The United States Geological Survey has published annual statistics show- ing the quantity and value of flint produced since 1892, and in the following' talkie there is shown tne total pro- duction and value for each year: Table 3. — I'lrxluiHiim nfjiiiil: lS9:i In UiOi.

The largest production was in 1894, when it reached 42,5(;(i short tons, and the smallest was 12,458 short tons in 1896. Since 1896, the production shows a steady increase year l)y year. The average price of crude flint in 1900, 1901. and 1902 was practically sta- tionary, varying- only from $1.73 to $1.86 per ton, while the average price of ground flint increased from $3.73 per ton in 1900 to$<',.72 per ton in 1901. and $6.79 per ton in 1901:!. The value of the imports for consunq)tion of flint and flint stones, unground, foi- the fiscal years ending June 30, 1900, 1901, and 1902. respectively, were $40,475, $64,697, and $85,092. The imports were chiefly from France, Denmark, and liejgium, in the order named, with more than half the values coming from France, and a small amount from (iermany. A detailed summary of the statistics for flint is given in Table 5. 0(viirri-ii the production was included in "quartz and feldspar," cited under "Flint" in this . report. The onlj' statistics pertaining to the feldspar production reported at the Eleventh Census, for the 3'ear 1SS9, with which comparison can be made are the quantit}^ produced and its value. The production was 6,970 long- tons, or 7,806 short tons, valued at $39,370. The aver- age prices for all material, crude and ground, for the census years 1889 and 1902, were §5.04 and $5.53 per short ton, respective!}'. There has been a very consid- erable increase in the production during the last decade, with slight increase in average value. As shown by Table 6, Pennsylvania had the largest number of feldspar mines or quarries, 12 in numljer, and produced one-third of the entire feldspar product and approximately one-half of the ground feldspar. There were 9 idle mines in 1902. Of the operators, 7 were individuals, 4 in Pennsylvania and 1 each in Alabama, Connecticut, and New York; 1 was an incor- porated company in New York, and 1 a firm (limited partnership) in Connecticut. The capital stock of the iiicorjjorated company- was 200,000 shares, all common stock, of a par value of $200,000, authorized; of which 150,000 shares, of a par value of $150,000, had been issued. The power of the idle establishments aggre- gated 42 horsepower, repoi'ted by 1 operator in Con- necticut and 1 in New York. Eiii]>Ioyei'S and 'iikkjck. — The wage-earners constituted 90.3 per cent of the salaried employees and wage- earners, and their wages were 84.2 per cent of the total salaries and wages. The average number of wage- earners employed by months is shown in Table 6. The maxinuuu immber, 279, appears in July, and the mini- mum, 227, in February, with an average of 252. Boys under 16 years of age were employed in two cases; 1 mine in Pennsylvania emploj'ed an average of 2 for the year, and 1 mine in Mar3'land an average of 1. The average number of wage-earners employed at specitied daily rates of pay is also shown in Table 6. The mines producing feldspar were all located in the Atlantic coast states, and, moreover, were all surface mines, no underground working being reported; hence the wages paid were comparatively low. Of the wage- earners, 61 per cent received less than $1.50 per day; 32 percent from $1.50 to $1.74, and but 7 percent $1.75 and over. Of the 183 miners or quarrymen, who constituted 73 per cent of all wage-earners, 69 per cent received not to exceed §1.49 per day and 3i) per cent from $1.50 to $1.74; only 3 miners received $1.75 or more. SuppJua^ materials, and nuiceUaneous expenses. — The cost of supplies and materials was $50,278, and the miscellaneous expenses, $19,407. Of the latter the sum of $10,584 was paid by 14 mines for royalties and rent of mine and mining plant, these mines being located — 4 in Connecticut, 2 in Maine, 2 in Mar3dand, and 6 in Pennsylvania; and $8,823 by 19 mines for rent of offices, taxes, insurance, interest, and other sundries. MecJumical i>oa>er. — Of the 27 mines or quarries, 13 emploj'ed f)ower aggregating 1,204 horsepower, of which 854 horsepower was furnished liy 15 steam en- gines and 350 horsepower by 7 water wheels. The waterpower was reported for 2 mines in Connecticut. 1 in Alaine, and 1 in Pennsylvania. I'l'ddiict'ujn. — The total production for 19ti2 was 45,287 short tons, valued at $250,424. This consisted of 21,87?(>.?A in 1899 to a maximum of $8.37 in 18'.t7. During the period from 1867 to 1883 the average value per short ton of imports of fuller's earth, hased upon the custom house returns to the Treasury Department, ranged from a minimum of §9.77 in 1870 to a maximum of i?11.25 in 1882, with an average of i81.'. Y.; Saline county. Ark.; Gar- field county, Okla. ; Custer county, S. Dak. : Cherrv count}', Nebr. ; Fremont countv, Colo. ; Kern county, Cal. ; and in I'tah. The Florida and Georgia deposits, which are very similar, do not resemble the English product. The fuller's etirth of South Dakota, however, is almost identical with the English earth, and mines in that sttite will probably in time become important producers. The methods of mining fuller's earth and preparino- it for the market are very simple. The overl)urden of sand and worthless plastic clay is removed, and the wet fuller's earth is chopped out in thin slices with mat- tocks and dried in the sun. The wet. greenish clav loses perhaps half of its weight, changes to a creamy wliite color, and becomes very brittle, easily splitting into thin layers. Artificial driers and an arrangement for grinding the earth to the re(:[uisite degree of fine- ness have been recently introduced. The Florida earth, grtiund to •!() mesh or finer, is used almost entirely as a substitute for Iwneblack in filter- ing mineral lubricating oils. The common practice is to run the earth into long cylinders, through which the crude black mineral oils ai-e allowed to percolate vtny slowly. The oil which comes out first is water white in color and much thinner than that which follows. While the Florida earth is superior to the English variety for the refining of mineral oils, the English product is nuich more desira1)le foi' the treatment of animal and vegetable oils. The process is radically ditlerent. The oil is heated in large tanks to a tem- FULLER'S EARTH. 1007 perature above the boiling point of water, and fi-om 5 to !(► per cent of its weight of fuller's earth, ground to 120 mesh, is added; the mixture is stirred vigorously for twenty minutes and then filtered otf through bag filters. Perhaps the most remarkable feature of filtration by the use of fuller's earth is the fact that — even in the mixture of oils present in crude petroleum— the oil which first percolates through the earth is the lowest in specific gravity. Indeed, the separation which can be secured by this process is comparable with the results of fractional distillation. Table 4:,^Lki(illed xurnmary: 190J.

The states reporting production in 1880 were New l^ork. North Carolina, and Pennsylvania. In 1889 there is no record of production in North Carolina, but oper- ations in Michigan, New York, Pennsylvania, Rhode Island, and "Wyoming were reported. In 1902 mining operations were carried on in 13 states — Alabama, Georgia, Massachusetts, Michigan, Montana, New Mex- ico, New York, North Carolina, Penn.sylyaiiia, Rhode Island, South Dakota, Wisconsin, and Wyoming. The period between 1880 and 1889 does not show so great a development of the industrj- as that between 1889 and 1902. the increasein the value of production being 213.1 per cent in the later period, as compared with 45.9 per cent in the earlier one; this advance was due largely to the increased demand for graphite in the arts. There were 12 mines — h in New York, 3 each in North Carolina and Pennsylvania, and 1 in Alabama — reported as idle during 19()2, and 3 — 1 each in New Hamijshire, New York, and Pennsylvania — at wdiich development work was done. Capital of Incorjjorati'd companieH. — Fifteen of the 19 active operators were organized as incorporated com- panies. The details of the capitalization of these companies are shown in the following tal)le: Table 2. — Capitaliziition af iricnrporaled compftmeit: WO'2. Number of incorp'ir- poses — for instance, to resist intense heat in the manu- facture of crucible steel; to possess great density at a high heat, as in the refining of gold and silver; and to resist the coi'rosive action of easily oxidized metals and alloys in a molten condition, as in melting brass, bronze, etc. Although crystalline graphite will burn in oxy- gen at and above a temperature of 575''-' C. , it is a good conductor of heat and electricity; this property renders it of special value for the manufacture of the conrnm- tator brushes used in electrical machines, for use in electroplating, and for electrodes in many electrolytic chemical processes. In its chemical relations, graphite occupies a position distinct from that of anj' other form of carbon. The most striking difference is the efi'ect of treatment with fuming nitric acid and potassium chlorate; diamond is unaltered, and amorphous carlion (charcoal) is com- pletely dissolved, but graphite is converted into a com- 230und known as graphitic acid or graphitic oxide (C„H,0,). As a fact of mineralogical interest, but one which has no industrial importance, it may be mentioned that meteoric masses have been found containing graphite which in its properties resembles the graphite formed during the cooling of high carbon and pig iron. Occurrence and mining cif crystalline graphite in the United States. — Crvstalline graphite is widely distrib- uted throughout the United States, but the known deposits of sufficient extent and purity to warrant working on a commercial scale are few in number. During the past decade the domestic output of high- grade crystalline graphite has been obtained chiefl}^ from the mines near Tieonderoga, Essex county, N. Y. The mines in Chester county. Pa., were reopened in 1897, after a long period of inactivity, and have been in continuous operation since that time. In 1899 the mines in Clay county, Ala., produced a small amount. There has been considerable activity in the exploitation of graphite properties in Bartow countJ^ Ga. ; near Dillon, Beaverhead county, Mont.; in Merrimack county, N. H. ; in McDowell county, X. C; at Bloom- ington, in northern New Jersey; and in manj- localities in California; but up to the present time the work has been confined chiefly to determining the character and extent of the deposits, and to ascertaining hy experi- ment the best method of concentrating the ore so as to convert it into a salable product. The limited number of graphite mines now producing the crystalline variety of the mineral bears witness to the difficulties encoun- tered in the development of a prospect into a paying property. 1014 MINES AND QUARRIES. The priiu'ipal mines in New Yorlv are at Tieoiideroga, Essex county. The g-raphite is of the foliated variety, occurring in Tuinute scales in the cleavage planes of a seam of gray cjuartzite. The ore contains an average of 10 per cent of graphite, of which but little more than one-half is extracted by the prevailing method of working. The graphite-bearing bed lies between strata of massive micaceous gneiss, garnetiferous gneiss, and light-colored quartzite entirely free from graphite. The gneiss dips about 2(»- south. The graphite lieds do not confoi-m to this dip, l)ut have a low pitch to the east. There are two mines in the same bed, on differ- ent sides of a fault. The graphite-bearing ([uartzite is from 1 to 5 feet thick in one mine, and from iJ to 1.5 feet thick in the othei-. This vein (known as the Hague vein) seems to have been in a line of weakness during the geologic uphea\a]s, for the ore and wall rocks near the surface are very much pulverized, so that, while the ore carries a good percentage of graph- ite, the yield is small. It is probable that the deepen- ing of the workings will result in finding the graphite in coarse Hakes in the unaltered rocks, mdess the faulting has occurred along the vein throughout its course. The mines are opened ])y adit levels, and the mined ore is treated for the separation of the graphite by crushing and washing in a mill near the mines, fol- lowed b}' a further refining at the works of the com- pany at Ticonderoga. There are numerous limestone deposits in Essex and neighboring counties of New York which contain graphite disseminated throughout the mass, or in small lenses of very rich ore. While a number of these deposits are being promoted and developed, the only ones of apparent promise are on Lead Hill, back of Ticonderoga, and on AVarner Hill, between Ticonderoga and Crown Point. It is proba))le that if any more val- uable mines are opened in this section they will be in the graphitic quartzite, as the lenticular bodies in the limestone have proN'cd uncertain. In Pennsylvania the principal graphite mine is 1 mile east of Chester Springs, Chester county. The mineral occurs in two layers of disintegrated mica schist, one 4 feet and the other ('< feet in thickness. Adit lev- els have been run in on the hillside, following the layei's, and the rock is so disintegrated that most of the oi'e can be removed by pick and sh(n'el without I'ccourse to blasting. At the null the ore is crushed in rolls and cleaned in a log washer of the type commonly used at clay works. After being washed it is again ground, refined by Y)neumatic concentration, and screened into different grades. There are other graphite properties in the state, notabl}' at Bycrs, several miles below Chester Springs, and at Pikeland, Ijoth in Chester county, and also at Mertztown and Boyertown, Berks county. These properties have been productive at various times, but for the most part are now inoperative. The exist- ence of graphite throughout a large part of the ridge extending from Phoenixville to the Brandywine river seems very probable. Occasionally pockets are found which yield nuggets and masses of nearly pure graph- ite, such as formed the basis of the producing mines in this region, but more often the mineral is associated with iron oxides, quartz, and feldspar, so that the extraction of the graphite involves consideraljle difficulty. Convoitrat'oKj cjijtttalline (jntph'de. — The increased demand for crystalline graphite has led to a careful study of the concenti-ation of low-grade graphite dis- seminated in Hakes. Operative plants have changed and improved their methods, and new concentrating processes are being tested. There are two conunon methods of concentrating crystalline graphite from its ore — the wet and the dry. The wet or water method has been developed to a marked degree of efficiency, and is the one now gener- alljr used. The mode of procedure is to crush the ore wet, and separate coarselj' by stationary' buddies, the concentrates being dried and further treated •with Inihr- stones and screens. No mill, however, has adopted either method in its entirety, because the specific gravi- ties of the constituents of the ore vary so little. Sev- eral pneumatic processes have lately proved a partial success, but they have been of limited application, on account of the impossibility of removing the small scales of mica which occur in some of the deposits. Two new features in concentration practice, in both of which the older method of complete submersion be- neath the surface is replaced l)y flotation, are worthy of note — first, the use of petroleum vapor, which, being readily absorbed by graphite, permits the flakes to be more readily separated from the gangue material l)y flotatif)n; and, second, the heating of the ground prod- uct l:)ef(.)re separation, which makes the flakes of graph- ite so light that they float on the surface of the water, whence the}' are removed. Occurrence and mining of aniorjdienix f/rii2>Jiite in the Uniteil Sfdfcs. — Under this head are included also the graphitic anthracite of Rhode Island and the so-called Baraga grapliite of Michigan. The incentive to develop properties containing amorphous gi-aphite is much less than in the case of the crystalline variety. On account of the limited use of the former, the value of the crude product is only from one-eighth to one-tenth of that of the latter. For the manufacture of graj)hite ci'ucibles and for many electrical purposes no satisfactory substi- tute for crystalline graphite has been discovered, while in the ease of amorphous graphite there are many other materials of equal suitability for its various uses. GRAPHITE. 1015 The mining of amorphous graphite in the United States has been of comparatively recent development. During 1902 the product was obtained chiefly from Wis- consin, followed by Michigan, Rhode Island, South Dakota, Wyoming, and New Mexico, in the order named. There are numerous deposits in other states, but none in sutBcient quantity or purity to l)e of com- mercial value at the present time. In ^^'isconsin, the mines near Stevens Point, Portage county, produce graphite which is reported to contain, at times, as much as 7-1 per cent of carbon. It is utilized in the manufacture of paint, lubricants, and greases. In Michigan, there are several thousand acres in Baraga county, composed of a carbonaceous schist without a sign of a vein of graphite. This material is ground for paint and is improperly called graphite. In llhode Island, the mines near Cranston have been operated for many vears. The graphite shows a struc- ture between scaly and granular, and the grade of the product has not until recently exceeded 55 per cent of car])on, the remainder of the ore being silica and iron oxide, with a trace of sulphur. The property was originally a quarry, and in making the open cut the vein has been exposed for a distance of 70 feet or more. A shaft has been sunk, and most of the ore is now obtained from pockets, although it is found also in a few fissure veins. In South Dakota, there are several graphite properties in the vicinity of Custer containing promising veins of graphite, one of which is reported to be i feet in width and of high-grade mineral. At Castle Creek, in Pen- nington county, 25 miles northwest of Custer, there is a vein which is reported to contain iO per cent of carl)on and to be in contact with a 10-foot layer of graphitized slate. In New Mexico, considerable exploratory work has been done at the graphite properties 8 miles southwest of Raton, Colfax county. Occurrence and mining of graphite in foreign coimtries. — In Ceylon, which is the chief producer of high-grade crj'stalline graphite, the main deposits are in the western and northwestern provinces. The graphite, which is scaly or fibrous in structure, is found in veins of irregular occurrence and extent, which break through crystalline rocks of the character of granulite. The minerals associated with graphite in the material which forms the vein are feldspar, rutile, pyrite. biotitc, and calcite. The country rock is often highly decom- posed, and then consists mainl}' of kaolin and similar decomposition products. The formation of graphite in these deposits has been attributed by Dr. Ernst Wein- schenk to the decomposition of vapors carr3dng carbonic oxide and cyanogen compounds. In one of the Ceylon mines near Caltura the graphite occurs in a series of veins in gneiss which has become converted, to a depth of 36 feet, into a mass resembling laterite. The indications point to the deposition of the carbon by the decomposition of hydrocarljon vapoi's, forming a true \n'in. The Ceylon mining industry, which is entirely in the hands of the natives, has been profitable for many j^ears, chiefly on account of the purity and consequent high value of the product. The method of mining is ex- tremely primitive. A shaft is sunk to the level of the ground water (from 40 to 200 feet), and drifts are cut from the bottom of the shaft until the air is so bad that the lamps of the miners will no longer burn; the ground is then stoped upward, the waste being dropped behind until the shaft is filled. In some cases the veins are followed ))y open cuts and galleries. The underground workings are roughly timbered, and powder is used to break the i-ock. The ore is hoisted by windlass and bucket, or passed out by hand. A peculiar feature of the industry is the opposition to the installation of modern mining machinery and methods, on the ground that the new conditions might be less satisfactory than the older and fairlv profitable ones. The mined prod- uct is famous for its purity, the analysis of several samples showing a carbon content of from 99.283 to 99.792 percent. In Austria, graphite occurs in the provinces of Bohe- mia, Styria, Moravia, Carinthia, and lower Austria. The chief producing mines are at Schwarzbach, in Bohemia. The deposits, which are lenticular, occur in gneiss, in parallel beds, extending over an area 11 miles long by 10 miles wide. At Schwarzl>ach six beds have been exploited for a length of 1,80(1 feet and to a depth of 300 feet. The mines produce both hard and soft ore, the latter being graded into three classes. The first and second are hand picked, dried, and packed in barrels for the mar- ket; the third class and the hard mineral are crushed in water and dressed in tanks, the heavier impurities sinking to the bottom, while the slime, containing the graphite in a state of fine division, is collected in a filter press, and the resultant cakes, containing about 50 per cent of carbon, are dried and shipped to the market. In Styria, which ranks second in importance, there is found a highlj' metamorphosed system of carboniferous shales, claj^-slates, limestones, and conglomerates with coal seams, the coal of which has passed into graphite. It is verv compact, very pure, and often extremely hard, in some cases I'ctaining exactly the appearance of the coal from which it has been derived. The graphite region extends from Leoben to St. Lorenzen, a dis- tance of 25 miles. The most important deposits are at St. Michael, where five parallel beds, varying in thick- 1016 MINES AND QUARRIF]S. nes.s from a few inches to several feet, and occurring in grayish-black schist, have been exploited for a length of over 600 feet. The preparation for market consists in simple screening. The product, which contains nearly SO per cent of carbon, is used in making graphite crucibles. Other graphite deposits are found in lower Austria, Moravia, and Carinthia; but the mineral, which is asso- ciated with granular limestone in gneiss, and is usually amorphous and friable, is too impure to warrant work- ing commerciall}'. The graphite deposits of Germany are confined to the easternmost corner of Bavaria. In a region bounded on the south by the Danube and on the east by the Aus- trian frontier are gneisses and gneissose rocks impreg- nated with scaly graphite. In some places — chiefly in the immediate neighborhood of intercalations of gran- ular limestone, altered by contact metamorphism — the mineral occurs in lenticular masses, rich in carbon. Both the graphite-bearing rock and its near neighbors are highly decomposed, so that kaolin and other decom- position products are found in intimate association with the graphite deposits. The lenticular form of the de- posits, their geological relationship with limestone inter- calations, and their f recjuent association with kaolin and other decomposition products, connect them closely with the Bohemian type, from which the}- are differ- entiated by the less compact and more crystalline char- acter of the graphite. The genetic connection between the Passau and Ceylon types is veiy close. At Borrowdale, England, fine-scale graphite was at one time found in veins in "greenstone porphyry." The gangue material was chiefly calc-spar, brownspar, and quartz, containing nests and lumps of very tine graphite, especially suitable for the manufacture of pencils. These mines, however, have been exhausted. The mines at Batugol, province of Irkutsk, Siberia, also are practicall}" exhausted. The graphite was finely fibrous and purer than that at Borrowdale. The veins run through a granitic or dioritic rock, while in th(> closel\' adjoining limestone (altered by contact meta- morphism) are great lumps of pure graphite, suitable onlj' for pencils. Artijielal hite. — Graphite can be made artificially in several ways, among which are the following: (1) In the production of cast iron fi-om ore containing a large proportion of carbon, l)y allowing the molten nmss to cool slowl}?. As cast iron can retain in combi- nation a much larger proportion of carbon when molten than when solid, the cooling of the mass causes the car- bon to separate out, forming scales of graphite dissemi- nated throughout the iron. It is to the presence of the scales of graphite that gray pig iron owes its peculiar properties and its graj' color. When this form of pig iron is dissolved in acid, the scales of graphite remain as an insoluble residue. AVhen cast iron is kept in a molten condition for a long time, as in the manufacture of converter steel, scales of graphite collect on the sur- face of the molten metal, forming so-called "kish." This source of artificial graphite is of no commercial importance. (2) By the reaction or decomposition of various chem- ical compounds containing carbon, notably the cj^anide class of salts. Graphite can not be produced commer- cially from chemicals on account of the excessiveh'high cost. (3) B3' the treatment of certain carbonaceous mate- rials in the electric-arc furnace, which is the process now used on a verj^ large scale. Pure graphite has many valuable iDroperties, such as high electrical conductivitv, great resistance to chemi- cal action, and absence of the property of absorbing gases, which is possessed more or less b}' all forms of amorphous carbon. Natural graphites of the high degree of purity required for delicate chemical and electrical processes are so expensive that in most cases the cost is prohibitive. The inception of the artificial graphite industry is due to the efforts and experiments of Mr. Edward G. Acheson,' who during 1897 manu- factured more than 160,000 pounds of this product. In 1901 the output in the United States reached 2,500,000 pounds. At first the operations were confined to the graphitization of carbon electrodes, but since 1899 very large quantities of artificial graphite have been made, to be utilized for purposes for which natural graphite was formerly used. In graphitizing electrodes the ordinary electrode, which is composed of a mixture of petroleum, coke, pitch, and a carbide-forming material (silica or iron oxide), is subjected to the intense heat of an electric-arc furnace. The so-called " artificrial graphite" is produced by subjecting anthracite coal, coke, or charcoal, together with a small proportion of some oxide or sulphate, to the intense heat of an electric- arc furnace; the impurities are eliminated, the ash be- ing reduced in some cases to as low as five-tenths of 1 per cent. The so-called artificial graphite, which is in the form of grains or powders, is used chieHy in the manufacture of jKiint, dry batteries, and commutator brushes, although a considerable quantity is used in the manu- facture of lul)ricants for high-grade work, in electro- plating, and in certain chemical processes which require a carlion of exceptional purity. Experiments have been made with this material as a coating for the grains of high explosives, to prevent the generation of the 1 United States patents Nos. 645284, 645285, 701758, and 711031. GRAPHITE. 1017 static charge of electricity, the spark from which is supposed to cause the spontaneous ignition of the powder. Graphitized electrodes possess special qualities which render them valuable in electrolytic processes for the production of caustic soda and of chlorine and metals in chloride solution, and in electro-metallurgical pro- cesses, such as the production of calcium chloride, the electric smelting of copper and iron ores, and the manu- facture of various iron alloys. In spite of the development of artiticial graphite, however, in recent j'ears there has been a large increase in the demand for natural graphite, due to the growth of the iron and steel industries; the largelj" increased use of copper and its allo3\s; the development of elec- trical machinery, which calls for graphitized products; and the increased need for special lubricants to be used at comparatively high temperatures. Uses of graphite. — Graphite is used for making ref rac- torjT crucibles, stove polish, foundry facings, paint, and lead pencils; as a lubricant; and in powder glazing, electrotyping steam packing, etc. For the making of crucibles crystalline graphite is required; the fibrous or laminated variety is used, because its superior binding qualities add to the strength of the crucible. The ordinary mixture consists of 50 per cent of graphite, from 35 to 45 per cent of air-dried claj% and from 5 to 15 per cent of sand. The graphite is ground to a fineness of from 40-mesh to 100-raesh size, according to the special use to which the crucible is to be put; if coarse it will give a porous crucible, while if too fine it will be apt to crack when heated, because of its great densitjr. The clay is selected, not on account of its refractoriness, but because of its plas- ticity. The sand is free from fluxing impurities, such as iron oxide, lime, magnesia, etc., and is sifted through a 4rO-mesh screen. In combining the constituents, the clay is made into a thin paste with water, and the graphite and sand are thoroughly mixed in by repeated treatments in an ordi- nary pug mill. The mass is kept moist for several weeks, in order to insure the expulsion of any air bub- bles which may have f)eeii formed in the mixing'. This stage of the work is called "tempering.'' A portion of the tempered mixture of the proper weight for a crucible of the desired size is molded into shape on an ordinary potter's wheel. This method is superior to ma- chine molding, l)ecause the rotary motion and external pressure cause the flakes of graphite to become arranged nearl}' parallel to the sides of the molded shape, thus binding the mass together more strongly. The freshljr- molded crucil>les are inclosed for several hours in a close-fitting sectional mold of plaster, which absorbs a portion of the moisture; they are then dried for a week or ten days at a temperature of from 70'' to SO'-' F., and finalh' are fired for several days in a common pottery kiln. The use for graphite crucibles of a fusible clay of great plasticity instead of one of high refractoriness is based upon the fact that for the combination of two substances l)y fusion mechanical contact is absolutely essential, so that, whether the clav be refractor}^ or not, the presence of an inert material between the par- ticles of clay and sand prevents fusion. Furthermore, as soon as the crucible is placed in the kiln the graphite on the outer surface is burned away by the oxidizing gases, permitting contact l>etween the particles of cla\' and sand; these, reacting upon each other, fuse and form on the outside of the crucible a glaze which pro- tects from oxidation the graphite flakes beneath the surface. The quantit}' of the mineral used for making lead pencils is comparatively small, but the qualit}' must be of the best. For use as a lubricant a high grade of the crystalline product is essential. But material of an inferior grade is employed in the manufacture of stove polish, of foundry facings, and of graphite paint, which is used to protect ironwork (as in smokestacks, iron roofs, elevated steel structures, etc.). While crystalline graphite is used to some extent, its special properties are not absolutely required, and hence the amorphous variety, both natural and artificial, is largelj' employed for these purposes. 1018 MINES AND QUARRIES.

By JosEi'H Hyde Pratt. The production of lithiimi ore has not been reported at any prior censufs, and there are, therefore, no com- parative statistics available. The mining- of lithium minerals for their lithia contents has been erratic in the United States, and it is onlv within the past few years that these minerals have been mined in any quantit}'. This is due to the small demand for lithium carbonate, which is the j^rincipal compound of lithium that is sold. The production for 1901 is stated by the United .States Geological Surve}' to have been 1,75() tons, valued at $1:3,200. According to the same autlioritj', 44(.) tons wei'e mined in 1900 in San Diego county, Cal., and probably between 75 and 1()0 tons were obtained else- where for experimental purposes. The following table is a summarj^ of the industry- for 1902: Table 1. — Sinnmary: 1903.

One mine, in South Dakota, was idle. Of the 3 oj^erators 2 were individuals and 1 was a firm. Eirqdoyees and vM(/e». — Of the total amount, $1,314:, paid in salaries and wages, $3,711, or 86.2 per cent, wa^ paid to the wage-earners. There were 2 wage-earners on the average to a mine. The yearly average number of wage-earners emplo_yed was 6, the greatest average number, as shown by Table 2, being 23 for July and August, and the least, .5 for September. Four of the 6 miners, or 66.7 per cent of the total, received from $1.75 to $1.99 per day. Production. — The production of lithium minerals in the United States during 1902 was 1,215 short tons, valued at $25,750. The world's annual production of lithium carbonate, which is the principal salt used, has been variousl}' estimated at from 50,000 to 15n,0n(.) pounds. Most of this is manufactured in German^', and a large proportion of the lithium minerals mined in the United States have been shipped to Germany, being returned in the form of lithium carbonate, quoted in New York at $1.35 per pound; the minerals are worth about $2(1 per ton f. o. b. at point of ship- ment. A small amount of ore has been treated at some of the chemical manufacturing plants in New Jersey, but thus far the}' have been unal:)le to make it a protit- al)le ]3roposition. A company in New York, which controls the larger proportion of the deposits of lithium )ninerals in San Diego county, Cal., expects to erect a plant on the Pacific coast for the manufacture of lith- ium salts from their own ores. If the estimate of 55,000 ^xjunds of lithium salts, reported as the annual consumption in the United States, is correct, over one-third of this amount is imported. To produce this amount of lithium salts would require 371 tons of mineral containing at least 3 per cent of lithia (Li^O); this indicates the relatively small amount of lithiiun minerals required to supply the home con- sumption of lithium salts. 0yed during each month: Men 16 years and over — June 21 July 23 August 23 September h Miscellaneous expenses: Total (rent of offices, taxes, insurance, interest, etc) S200 Cost of supplies and materials SI. 2t'i-i Product: tjuantity, short tons 1, 24.5 \'alue S25, 7-50 1 Includes 2 operators in California and 1 in South Dakota. MARL (1023) MARL. By Stouy B. Ladd. The statistics of marl presented herewith rehite to the marl product mined and used as a fertilizer, and are confined to the greensand deposits found in New Jersey, Delaware, Maryland, and Virginia. At the Tenth Census no statistics in regard to marl were published. At the Eleventh Census the total production of marl in the United States for the year 1SS9, was 139,522 short tons, valued at $63,956. The production was limited to five states, viz. New Jersey, Virginia, North Carolina, Alabama, and Arkansas. In four of the states the production was very small. New Jersey alone producing 99 per cent of the total. During the period 1889 to 1902 there was a very extensive development in the manufacture of Portland cement from the marls of Michigan, Indiana, Ohio, and New York, in the lake region, resulting in a consump- tion of over a million cubic yards of the material, but as this was all manufactured into cement it is considered in connection with the statistics for cement. Table 1 is a summary of the statistics for the marl industry as reported for the year 1902: Table 1. — Summary: 1902. Number of mines or quarries H Number of operators 11 Salaried officials, clerks, etc.: Number 2 Salaries S2, 100 Wage-earners: Average number 13 Wages J4, 769 Miscellaneous expenses SI, 407 Cost of supplies and materials S2, 755 Product: Quantity, short tons 12,4:59 Value .: S12.741 Of the 11 mines or quarries for which production was reported, 10 were in New Jersey and 1 was in Virginia. The Virginia mine was in Prince George county and the New Jersey mines were distributed as follows: 1 in Burlington count}', 1 in Gloucester county, and 8 in \ Monmouth county. One hundred and four properties reported to the United States Geological Survey as in operation in 1901 were idle during 19()2. All of these were in the state of New Jersey, and were distributed as follows: Burlington county, 52; Camden county, 1; Gloucester county, 2; Monmouth county, 48; and Salem county, 1. As but 1 producer outside the state of New Jerse_y reported in 1902, the statistics are presented for the United States as a whole. Capital stock of incDi'pomted cimpavles. — Of the 11 producers, 2 were incorporated companies — 1 in New Jersey and 1 in Virginia — but neither was engaged ex- 3022:3—04 ti.5 clusively in mining. Their authorized capitalization consisted of 5,380 shares of common stock, of a par value of 167,300. All of the stock was issued but no dividends were paid on it. EiiiphiygiiK (irid 'inKjes. — But 1 producer reported sal- aried employees; these were 1 superintendent and 1 clerk. The small number of wage-earners employed — 13 by the 11 producers — shows that the work was done largely by the owners themselves. The work is all above ground, being mere excavation. Only one es- tablishment reported the employment of power, with 2 employees classed under ''engineers, firemen, and other mechanics." Of the total amount, $6,869, paid for salaries and wages liy the 11 producers, the sum of $4,769, or 69.4 per cent, was paid to the 13 wage- earners, and $2,100, or 3(_).6 per cent, to the 2 salaried employees. The variation in the number of wage-earners employed at different seasons of the j'ear is shown by Table 3, which gives the average number of men and boys, respectively, employed during each month. The small number of wage-earners reported for each month will not warrant any deductions. It mav be said, however, that more laborers Hnd emplojnnent late in the autumn and early^ in the .spring, when the farming operations of the proprietors are practically suspended. Thus the range in 1902 was from 10 wage-earners during Januarys and Februar\'and during the summer to 17 in November. In addition to asking the average number of employees and the total amount paid as wages, the schedule called for the number of wage-earners employed at the speci- fied daily rates of pay, and these statistics are also shown in Table 3. The excavation of marl requires no skill and the rates of pay should not be compared with those paid in other mining industries requiring skill and experience. Thirty-eight and four-tenths per cent received less than $1 per day; 30.8 per cent, from $1 to $1.24; and 30.8 per cent, from $1.50 to $1.74. Supplies, materials, and miseellanenns e.rpenses. — The total amount expended for supplies and materials was $2,755. Most of this is chargeable against 4,267 tons of marl dried and ground. The amounts chargeable against the 8,172 tons of crude marl reported is less than 3 cents per ton. The total amount reported for miscellaneous expenses, $1,407, is also for the most part expense chargeable to the treated product. It was paid for "rent of othces, taxes, insurance, interest, (1025) 1026 MINES AND QUARRIES. and other ,sundi'ie.s." iiiul no expense was reported for " royaltie.s and rent of mine and mining plant." Of the 11 producers, 7 reported no expense for supplies and materials, and S, no miscellaneous expenses.

The former was valued at lii-l,^^.!) and the hitter at $7,876. This shows an average value of $1.02 per ton for both crude and treated marl. The average value per ton for crude marl used as a ferti- lizer without previous treatment was $0.59.5; the aver- age for the treated product was $l..s45. The detailed statistics of the marl industry for ll:t(.)2 are given in Table 3. DESCKIPTIVE. Marl in a general sense is a mixture of calcium car- bonate and clay, occurring naturally with more or less siliceous sand. It is sometimes ronipact and sometimes pulverulent, and there is a wide range in the character of the material to which the term is applied in difl'erent localities. The term ""greensand" is given to marl having a green color, liecause of the presence of grains of green silicate of iron. Most of the A'arietics of marl found in the United States conform to the general defi- nition, and have calcium carbonate as their ])rincipal constituent. The cretace(.)us marls of New .Jersey, as a rule, contain lime in small and variable amounts, and also considerable potash and plji.isplioric acid. The fertilizing value is due chiefly to these hist two constitu- ents. Potash constitutes from 3.5 ])er cent to 7 per cent, and phosphoric acid from 1.25 per cent to !• ])er cent of the whole. The marls of New Jersey have long been used; in some 3'ears very extensivel}'. Marl improves both the chemical and ph3^sicai con- ditions of the soil, neutralizing acidity, making available plant food otherwise insoluble, and promoting nitrifica- tion. It is very lasting in its etl'ects, and has been used from ancient times for restoring worn-out and improv- ing barren lands. On account of its bulkiness and the large amounts required to secure beneficial results, marl can be used profitably only in close proximity to the deposits. Mr. James C. Booth, in a report of the geological survey of Delaware for l.S-H, recommends the u.se of from 60 to 100 Inishels per acre on light soils and from 100 to 200 bushels on cla}' soils, and states that from 200 to 500 bushels may be used on soils of good quality abundantly supplied with humus. The addition of tO per cer.t of quicklime to the marl ([uickens its action.

The 49 mines reported in operation during 1902 were located in the following states: North Carolina, 2S; Cali- fornia, 1(1; South Dakota, 'A\ Maine, 2; New Hamp- shire, 2; Virginia, 2; Georgia, 1; and New Mexico, 1. Of the 3S operators, 20 were in North Carolina, 3 in South Dakota, 2 each in Maine, New Hampshire, and Virginia, and 1 each in California, Georgia, and New Mexico. Of these operators, 18 were individuals, 11 were firms, and 9 were incorporated companies. North Carolina was the main producer of mica in the United States; in 1902 the value of its production was .59.8 per cent of the total. The total amount of salaries and wages paid in 1902 was $1.5,313 more than the amount reported for 1889 and §8,1 L3 le.ss than at the census of 1880. The production reported in 1902 was 373,266 pounds of cut or sheet, 1,028 short tons of scrap or waste, and 372 short ton.s rough as mined. This production of .sheet mica is about five times that reported in 1880 and nearly eight times that for 1889; but the total value, $118,849, of all the mica produced in 1902, although much more than that shown for 1870, is $8,976 less than the value of the production reported at the census of 1880. This is due in part to the somewhat higher prices received in 1880, and also to the very large ciuantity of small disks and sheets cut in 1902 for electrical purposes. The decrease of $75,376 in value between 1.S80 antl 1889 reflects the decrease in production and fall in price caused by the large amount of mica imported from India. The reporting of 196 tons of scrap or waste in 1889 indicates the beginning of the use of mica in the manufacture of wall papers, lubricants, etc. The principal changes in the mica industry, since the census of 1890, h'AXB resulted from the utilization of the scrap mica, which was formerly thrown away as valueless, and the cutting of large quantities of small disks, 1 inch in diiuneter, and small sheets 1 \)\ 1\ inches and 1 by 2 inches, for electrical purposes. This waste having become of value it is possible to work properties which would otherwise be unprofitable. Manj' new uses for both .sheet and scrap mica have been devised during the past few years, so that although there has been a very large falling oS in the amount of sheet used in stoves (which was formerly the princijjal use of mica) the quantity of all mica used has greatl}' increased. The mines that were idle in 1902 number 36, of which l-t were in North Carolina, 5 each in New Hampshire and Idaho, 3 in New Mexico, 2 each in Alabama and South Dakota, and 1 each in Georgia, Nevada, Ohio, Pennsylvania, and Vermont. They were owned by 34 operators, of whom 21 were individuals, 7 were firms, 5 were incorporated companies, and 1 was a cooperative association. The authorized capital stock of the 5 incor- porated companies was $1,100,000, of which shares to the value of $229,500 were issued. The assessment levied amounted to $1,600.

Eiiipli>yees and vxkji'S. — The total number of em- ploj^ees reported for the mica industry in l'..t02was 119, comprising 21 salaried emploj'ees and an average dur- ing the j'ear of 98 wage-earners. The^^ received in salaries and wages $.57,187, of which amount $13,111, or 23.4 per cent, was paid out in salaries and $14,043, or 76.6 per cent, was paid out in wages. The month in which the greatest numljcr of wage- earners was engaged, as shown in Table 6, was August, when the number amounted to 112; the lowest was in Januarv, with 75. The falling off during the winter months of January, February, and March was in "all other states." It is interesting to note that there were no wage-earners under 16 years of age employed. The average number of wage-earners at specihed daily rates of pay is also given in Ta[)le 6. The wages received varied from 75 cents to $3.71 per day, the most usual rate, however, being from $1 to $1.24. There were 62 wage-earners whose wages were less than $1.25 per day, and of these 19 were classified as miners. These low wages are accounted for by the fact that most of the mining was carried on in North Carolina, where there is a low scale of wages. The miners in the Western states command higher wages as indicated by the fact that the 12 miners wdio were reported to have received from $2.5(» to $2.74 per day were employed in western mines. Of the 98 wage-earners, 81 worked above ground and onlj' 17 below ground, indicating that most of the mica mining was done in shallow pits and cuts. It was not extensive enough to require much underground work. The number of wage-earners classified as miners was 70. Of these 58 worked above ground and 12 below ground. One foreman was reported employed below ground; therefore, the total number of underground miners was 13, and of underground employees l.S. Supplies, iiiiiterialu, mid m iscelhineous expenses. — The total cost of supplies and materials and miscellaneous expenses, reported at the census of 1902 for the mica mining industry was $24,875, of which $11,961 was paid for supplies and materials inquired in mining the mica; $3,112 for royltiesand rent of mines and mining plants; and $9,772 for rent of offices, taxes, insurance, and oth(.'r sundries. Mechanical potrrr. — The total horsepower utilized in the mica industry was 201, generated by 8 steam engines with 160 horsepower; 1 gasoline engine with 25 horsepower; and 1 electric motor of 16 horsepower. Of this amount, only 10 horsepower, generated by 1 steam engine, was used in North Carolina. Prodiictu'jii. — The production c)f mica in 1902 con- sisted of 373,26(; pounds of cut, sheet, or plate, valued at $83,813; of 1,028 short tons of scrap or waste, valued at $13,081; and 372 tons rough as mined, valued at $21,925, making the value of the total production $118,849. The 372 tons of mica rough as mined would yield approximatel}' 160,000 pounds of cut, leaving 297 tons of scrap. The large increase in the production of sheet mica during the past few j-ears has been accompanied by a large decrease in the production of scrap mica. This decrease is accounted for b}' the fact that most of the scrap mica now produced is that obtained as waste in the present mining or cutting of the sheet mica, where formerly a veiy large percentage put on the market was obtained from old dumps from former mining.

The main point to be noticed, however, is that this increase is greater than the total value of the production of mica in the United States during 1902, showing that the increasing demand foi' mica in this country is l)eing supplied largely by foreign countries. The relatively small production of mica in the United States as compared with the importation can be ac- counted for partially b^' the low prices maintained for plate mica, by the uncertainty of the occurrence of mica in the veins, and by the large number of small producers each depending upon one small mine. A\'hen the mica in the mines of these small producers begins to give out or becomes poor, they do not have the means to carry the necessary amount of "'dead" work. The importation of mica from Canada and India at a low valuation tends also to curtail the production of mica in the United States because t)f the influence it has on the prices of the mica produced at home. This is especially true of the mica imported from India, which can be mined and landed in this country at a price lower than the cost of production at some of the mines in the United States. The detailed statistics of the industry for 1902 are given in Table (!. DESCRIPTIVE. Occurrence and u.^e. — Mica, in some form or other, is probabl}' familiar to everybody because it is so very widely distributed in nature, being a component part of ' many of the crystalline and sedimentary rocks. " Its \ commercial value is dependent upon its occurrence in 1 blocks or masses that are capable of being ,split into I sheets a square inch or more in size. Deposits of com- mercial mica occur for the most part in jDegmatitic dikes or veins which arc found in granite and hornblende and mica gneisses or schists. These dikes or veins vary in thickness from a few inches to several hundred feet and are often very irrcgidar, having arms or veinlets branching off in many directions. In character, these dikes are similar to granite, and sometimes they are called "coarse granite,'' and if we could conceive of the constituents of granite being magnified a hundred times or more we would have an appearance similar to a peg- matitic dike. The mica in these pegmatitic dikes will seldom aver- age ovrr 10 per cent of tlie contents of the dike and sometimes will be as low as 1 per cent. Often a dike will have the appearance of containing a verv high per- centage of mica on account of a numlier of blocks })eing clustered together in bunches almost touching each other, while in another portion of this same dike the mica will be almost entirelj- absent for a distance of from 5 to 20 feet; thus the general average of mica in the dike will be from 1 to 10 per cent only. Of the mica obtained from these dikes, usually only from 5 to 25 per cent can l)e cut into sheet or plate mica. The average is probably about 10 per cent. Occasionally large quantities of mica are mined in which there is not over 1 per cent that can be made into sheet mica. These commercial occurrences of mica are not very abun- dantly distributed throughout the United States, al- though rocks in which mica is one of the chief constitu- ents are very common. At the present time deposits of commercial value are known to occur in Alabama, Arizona, California, Colorado, Connecticut. Georgia. Idaho, Maine, Missouri, Nevada, New Hampshii-e, New Mexico, New York, North Carolina, Rhode Island, South Carolina, South Dakota, Vermont, Virginia, and Wj'o- ming: and in Arkansas there are also deposits which may become of commercial importance. In most of these states the deposits were not worked in 1902. In some of them the deposits were not available on account of their distance from I'ailroads, this being especiallv true of those in Arizona, Colorado, Nevada, New ]\Ie.x- ico, and Wyoming. In others little has been done owing to the uncertaintv of the price and the demand. Many of the dejiosits of Maine have onlv recently been opened, and therefore have not been extensively devel- oped. INIicii was first produced in the Eastern states along the Appalachian mountains, and twenty years ago mining was carried on vigorously in Connecticut, New Hamp- shire, North Carolina, and Virginia. In the eastern field the principal mining is in North Carolina, which, since the beginning of the mica industry in the United States, has been the chief producer of the mineral. At just what time the first work was done on the mica de- posits of North Carolina is uncertain, and since there 1032 MINES AND QUARRIES. is no record of the old mining- and none of the inhabi- tants of this section have any information whatever re- garding these old workings, they have been attri))uted to the Indians. Trees 3 feet and over in diameter have been observed growing from these cuts. Stone imple- ments have been found in some of the old tiunieis, indi- cating the antiquity of these workings. Most of these old mines are located in Mitchell and Yancey counties. Of the North Central states. South Dakota has been and still is the state in which the largest ([uantity of mica is produced; while of the Western states and ter- ritories, New Mexico has for a number of years been the largest producer, but is now likely to have to give way to California. These California deposits have only lieen opened up within the past few 3-ears, but the mining is now being carried on quite extensivelj'. At the present time the Nevada deposits are too isolated to warrant mining on an extensive scale. The completion, however, of the railroad, which is being constructed from Cali- fornia across Nevada and Arizona to Utah, will make these deposits more available for commercial purposes. The uses of mica are somewhat varied; there are two forms in which it is used, (1) sheet or plate mica and (2) scrap mica. Sheet or plate m tea. — Mica is cut into sheets of various sizes which are used for stoves, lamp chimneys, incan- descent lights, and in electrical apparatus for insulation purposes. While the use of this sheet mica for stoves has decreased very rapidly during the past ten years, there has been a corresponding increase in its use for electrical apparatus. It is also used in place of glass in the manufacture of a great many novelties and in many respects increases the usefulness of the articles made. There was formerly a considerable demand for the larger sheets of mica, but these have been replaced to some extent at the present time by a manufactured product known as micanite, which is made from very small, perfect pieces of mica rearranged and cemented together into larger sheets. For some purposes these manufactured sheets are as satisfactory as the natural ones and are, of course, much cheaper. The value of sheet or plate mica varies with the size of the sheet and is from 2 cents to $3 per pound. The values of from 2 to .5 cents per pound are for the small disks and rectangular sheets that are cut by machinery and are used extensiveh' in electrical apparatus. The larger sheets are cut by hand and considerable skill is required to cut the largest pattern possible from the crude block of mica. Scrap mica. — The waste or scrap mica not suitaljic for cutting into sheets of even the sniallest size has a value when ground to a flour, which is used in the manufacture of wall papers, lubricants, tireproofing material, artificial snow, novelties, etc. Coverings for boiler tubes and steam pipes are also manufactured from particles of scrap mica which are not ground but are broken into pieces of approximate! v the same gen- eral dimensions, one-half by one-fourth of an inch. These are then arranged with their longer dimension and face parallel to the length of a wire net coil, pressed into the shape of a pipe or tube, against which the layer of scrap mica is kept tightly in place by means of heavy canvas. A number of the states, especially North Carolina, offer very favorable locations for the erection of plants to manufacture products from scrap mica, as there is usually a supply of available water- power near the deposits. The commercial value of scrap mica before it is ground is from $8 to $10 per ton, delivered at the rail- road, and it is this value that has made it possible to work some of the mines that otherwise would have been shut down, for in some cases this waste mica represents from 7.5 to 95 per cent of the mica mined. After being ground, the mica is worth from Sl<» to S6M per ton, according to its mesh. There are a number of minerals, especially quartz and feldspar, associated with the mica, which in some instances should prove of considerable commercial value as by-products in mining the mica, provided water- power for grinding these minerals can be secured near the source of supply. Occasionally some of the gem minerals, as beryl and tourmaline, are found associated with the mica, and furnish some very handsome cut stones. Some of the pegmatitic mica-bearing dikes are rich in the variety of minerals that they contain, while others have very few besides those typical of a peg- matitic dike. Between forty-Hve and flfty difi'erent minerals have been found associated with mica at the difl'crent mines thi-oughout the country. The small production of mica in the United States as compared with the importation is not due to a defi- ciency in the supply of the mineral in this country. It is uiuloul:)tedly true that in the Appalachian region, especially in the southern area, there are many good deposits of mica yet to be discovered which will yield as rich returns as many of those that have already Ijeen unned. It is also true that many of the mines that were worked so extensively twenty years ago, espe- cially those in North Carolina, still contain good de- posits of mica which the former owners were prevented from taking out on account of the presence of water, which they were unable to control with the means that they had at hand. Any increase in the duty on mica or any considi'rable decrease in the importation of mica from India and Canada would cause an increase in the pi'ice of mica, and would result undoubtedly in a large and immediate increase in its production in the United States.

MONAZITE (1035) MONAZITE, Bv -Joseph Hyde Pkatt. There i,s no mention of the monazite indu.strv in any previous census report, for the reason that the pro- duction of this mineral for commercial purposes did not reallj' begin until l.S9o. As earlj- as lisT9 the exist- ence of monazite in commercial quantities in North Carolina was proved l)y W. E. Hidden, but it was not until 18.ST that the tirst shipment was made. During that year 12 tons of monazite sand from the Brindle- town district, in Burke county, N. C were shipped for experimental purposes, and in the following two years, 1888 and 1889, a few tons were shipped to a northern companj'. The statistics for 1903 are sum- marized in the following table: Table 1. — Siimiiiurij: 1902. Number of mines 23 Number of operators 22 Salaried officials, clerks, etc.: Number 3 Salaries $2, 100 Wage-earners: Average number 88 Wages .S25, 318 Miscellaneous expenses S2, 083 Cost of supplies and materials ^256 Product: Quantity, pounds S02, 000 Value S61, 160 One mine in North Carolina was reported idle during 1902. The industry is one of placer mining and is irregularly carried on in many instances, the expenses of some of the producers being advanced by the opera- tors of a concentrating plant. It was deemed inadvis- able to obtain separate statistics for these three or four hundred small and irregular miners. Over half the quantity of monazite produced during 1902 is credited to them. This is accounted for in the report of the concentrating plant which purchased the mineral, the miners selling monazite to such plant being included in its return as employees engaged in mining by the pound, and the total amount paid foi' the mineral being given as their wages. The nunilier of these irregular contract miners was reduced to <)5 — the number com- puted to have been working 300 days during the year — and is included in the statistics here presented. The number of placer deposits or mines for which statistics were received at the census of 1902 was 23. Of the 22 operators working these mines, 2(» were indi- viduals, 1 was a firm, and 1 an incorporated company. The incorporated company had a total authorized capital stock of $500,000, divided into 10,000 shares, of which 20 shares, with a total par value of $1,000, had been issued. Em j>Joyeeti andvKigi^H. — Of the total amount, 127,418, reported as paid for salaries and wages, $25,318, or 92.3 per cent, was paid to the wage-earners and 12,100, or 7.Y per cent, to the salaried employees. On an average, there were 3.8 wage-earners to a mine. The average num);)er of wage-earners by months and their daily rates of pa}' by occupations are given in Tal)le 3. The maximum, 130, was reached in August and the minimum, 20, in November and December. Of the 88 wage-earners, ^i'o were classed as miners. Of these, 73 received from $1 to $1.21 per day, and 13 from 75 to 99 cents. Supplies, mater iah, (uidinhceUaneom expenses. — Only $25t] were reported to have been expended for supplies and materials. Next to the amount paid for wages that for miscellaneous expenses, $2,083, is the largest. Of this $1,739, or 83.5 per cent, was paid for royalties and rent of mine and mining plant. Mecliaii'teaJ penrer. — Of the 22 operators only 1 re- ported power. This was a firm in North Carolina, which owned 2 steam engines with a total of 30 horse- power. Pr(i(Jii<:ti less pure sand sold hy the small producers who were able to eliminate only a small percentage of the heavy minerals. At the present time the sand mined ))y the small producer is sold to the concentrators and is paid for on the basis of its value after it has been concentrated as thoroughly as possible, so that during the past year or two the price reported by these small producers has increased from 4 cents per pound for crude sand to 8 or 9 cents per pound for the retined product. The entire prodaction reported at the census of 1902 is credited to North Carolina. Since the beginning of the industry monazite has been produced chiefly in North Carolina, although at first a considerable quantity was obtained from Spartanburg countv, South Carolina. The production of monazite in commercial quantities became a well established industry in 189.3. the output for that year being 130, Ooo pounds, valued at §7,000; during the next two years tlu^ production increased verv rapidly, until, in 1895, it amounted to 1.573,000 pounds, valued at 1^137.150, or about 9 cents per pound. It was at this time that the Brazilian deposits of monazite, which occur in large quantity as beach sands along the seashore in the extreme southern part of the province of Bahia. Ijegan to be worked on a consider- able scale; the production in the United States was affected thereby to such an extent that by the end of 189fi it had decreased to 3(».ooO pounds. In 1S98 there was again a considera})le demand for North Carolina monazite, and the "|3roduction amounted in that year to 250,770 pounds, valued at $13,54:2. Since that time the production of this mineral has increased, and at the census of 19()2 it was 802,000 pounds, valued at ^JfU, lOo. It sometimes happens that while the (juantity of monazite sand produced in a particular year is moi'e than that for the j'ear following, the value of the pi'oduction of the latter year is considerabl3' more than tliat of the former, because of the higher percentage of monazite obtained by a more thorough cleaning of the sand. The monazite industry is steadily increasing, and there is now a consideral)le deinand for this mineral, not onlj' in this country but also abroad. During 1902 a German company was organized and bouglit up monazite lands in North Carolina. Tiiis company has erected the most complete concentrating plant in the district. Its production is to be shipped al)road. DESCRIPTIVE. Occurrence. — The connuercial deposits of monazite do not occur in the original rocks, which are granitic mica gneisses and hornblende gneisses, and contain only a fraction of a per cent of this mineral; they are found in the placers of the present streams and rivers, and in the old sand and gravel deposits of former streams. As these gnei.sses are constantly being decomposed and disintegrated, the monazite is continually being washed down and deposited so that in many cases the top soils form workal)le deposits for monazite sand. The area in which these deposits are located is in Burke, Cleve- land, McDowell, Polk, and Rutherford counties, N. C, and in the northern part of Spartanburg and York coun- ties. S. C. They are found along the following streams: Silver, South Muddy, and North Muddj' creeks, and Henry and Jacob forks of the Catawba river, in Burke and McDowell counties; the Second Broad river and its tributaries in McDowell and Rutherford coun- ties; and the Broad river and its tributaries in Cleve- land and Rutherford counties, N. C, and Spartanburg and York counties, S. C. All these streams have their sources in the Soutli mountains of North Carolina. Pracexs (if rlediiuiij. — The \'alue of monazite sand is dependent principally upon the oxide of thorium, and to a less extent on the oxides of cerium, lanthanum, and didymium. As the thoi'ium oxide or thoria contents are due to the jjresence of the mineral monazite, the neai'er to a pure monazite that the sand can he cleaned, the higher the percentage of thoria. Formerly a sand containing from 05 to 7o per cent of monazite was con- sidered of very good c[uality; now, with improved ma- chinery and new methods a sand can be obtained that is over 95 per cent monazite. In washing the sands, the lighter material is readily floated otf, but magne- tite, menaccanite (or ilmenite), rutile, brookite, garnet, zircon, etc., remain with the monazite. The magnetic minerals, such as magnetite and menaccanite are then re- mo\'ed. Formerly the other minerals could be onlv partially cliniinated. l)ut now, with the improved elec- tro-magnetic separator, the other iron minerals are readily picked out; the final operation is the picking up of the monazite grains, leaving the zircon, corun- dum, etc. In tliis way an almost pure monazite con- centrate is obtained. TJ.scx. — The principal use of the oxides of thorium, lanthaiuun, and didjnnium is in the manufacture of the cylindrical hoods of the Welsbach and other incandes- cent gas lights. Small cjuantities of the cerium oxalate obtained during the process of separating the other oxides are used in pharmac}'.

Bj' George F. Kunz. In the United States precious stones have been j^en- erallj' found by iiecident; in prospecting for, operatino-, or developing- mines of other minerals; or in the work- ing of gTavels containing gold, raonazite, etc. With the exception of the tigures relating to the number of operators and the value of production, the statistics herewith presented are for properties operated by com- panies which carry on the search for stones with some approach to regularity. These companies produce sap- phire, tourmaline, beryl, chrysoprase, opal, and tur- quoise. In addition to these, certain quantities of em- erald, peridot, several varieties of quartz, such as rock crystal, smoky, rose, gold, and rutilated (|uartz, ame- th3^st, agate and moss agate, and silicified wood; also garnet (pj'rope and rhodonite), amazon stone, chloras- trolite, niesolite, pyrite, anthracite, and catlinite, were produced in this countr3' during 1902, but not on a large scale, nor under conditions suitable to serve as a basis for statistical treatment. In discussing this subject, consideration of the pecul- iar condition under which production is carried on, and of the noncommercial uses of the product, is of impor- tance. No comparison of the returns in 1902 with those of the Eleventh Census is practicable, owing to the dif- ferent methods by which these reports were made uj). Moreover, it is difficult to present any careful analysis of the tigures, and the results necessarily are uncertain. The data in Table 1 are based upon trustworthy infor- mation derived from the operators. The value of the turquoise produced amounted to .$130,000, or .39.6 per cent of the whole, and of sapphire. $11.5,000, or 35 per cent. Much of the production of precious stones was more or less accidental, picked up by prospectors for other minerals, or by excursionists along the beaches. This fact will explain the apparent inconsistenc}^ between the small number of mines and the large number of operators reported. It will be readily understood that in such cases no items of expense are properly chargeable. The statistics fol- lowing, with the exception noted above, are for those companies actively engaged in the s^^stematic exploita- tion of precious stone deposits. The peculiar condition existing, however, should not be lost sight of. There were 3 mines, 1 each in California, NewMexico^ and North Carolina, reported idle during 1902.

A detailed summary of the statistics for the* mining of precious stones in the United States during l'.t()2, where the operations wer(>. followc^d on a commercial basis and warranted statistical treatment, is given in Table 4. I)^:SCKIPTIVE. Precious stones derive their value chiefly from their rarity. Other (juaiities tliat influence their value are beautjr of color, hai'dnrs.s, .■md Ihc caijricc of fashion. Under this classiHcalion a, distinction coidd he made between precious and semi|>reci()u.s stones, but it is not obserA'cd in this discussion. Precious stones include the diamond, the sapjihire, the ruby, and the emerald; semiprecious stones include a wide variety of other gem minerals. The opal and the [learl art^ sometimes classed as precious stones, although the latter is not strictlv a mineral jirodnct. In ordinary specM'li the precious or semiprecious stonc^ signities a gcMu cut or polished for ornamental purjioses. In minei'alogy the term is used to designate a class of minerals of sufficient liardness to scratch (|uart/. which ar<' without metallic luster. PRECIOUS STONES. 1045 although generally brilliant and beautiful. In archae- ology the term is restricted to engraved stones, such as intaglios and cameos. A jewel is a gem that has been mounted. In the report of the Eleventh Census upon "Mineral Industries," page 609fl', an account is given of the occur- rence and production of precious stones in this country during the year 1889. The present discussion treats only of the discovery and production of precious stones in the United States since that time. Diamond. — The diamond, the hardest of known sub- stances, is pure carbon, which crystallizes in the iso- metric system, generally in an octahedral foi-m. Its specific gravity is 3.525. It occurs in a great variety of colors, ranging through all the shades of the spec- trum, occurring most frequently as write, yellow, or brown, and rarely as red, rose-red, blue, , -^n. Bv . , " 1 ,. T 1 ^artz oi ^ tar the greatest number of diamonds coi „,, ■ .i bouth Africa, but they are found also in Brazil, J , Borneo. as I and occasionally in North America. , , In the United States diamonds have 1,;, .'ound at various points, but they have been few in ^aiber, and mostly of small size. Their occasional occurrence in California and east of the southern ALlteghanies has l)een known for fifty years. Since ISyO a few others have been found in these regions, and some in the North- western states, varying from one-third of a carat to 21 carats in weight. The northwestern diamonds are very interesting as being contained in the deposits of the glacial drift, scattered along an irregular line of some (ioO miles, from Wisconsin to the vicinitj' of Cincinnati, Ohio. All the material distributed by this ancient glacial action has been lirought down from the north, and tlierefore the source of these diamonds is somewhere in the unex- plored regions of Canada and not in the United States. Geologists recognize two distinct drift deposits in the Western states, called the older or lUinoian drift, and the later or Wisconsin drift. Some of the diamonds found in Indiana and in Wisconsin are referred to one of these drifts and some to the other, though most of them belong to the later. The whole number of diamonds actual^ known from these glacial deposits amounts to about 25, over half of which are from Wis- consin and one-third from Indiana. The localities of discoverjr during the period since 1890 are as follows: Alahama. — Shelby county, one of 41 carats. Lee county, one of 3 carats. Cidifoniia. — A number of localities, chiefly in the central portion of the state, in connection with the hydraulic Kold washings of Amador, Butte, Eldorado, and Nevada counties. A single dia- mond is reported from Tulare county, and a number of very small ones in the gold sands of streams in Del Norte and Trinity counties. No large stones have been found in California, and nowhere are they abundant enough to lead to any mining for them. Never- theless some handsome ones have been casually obtained in the central counties above named, chiefly in the ancient gold-ljearing gravels overlaid by lava flows, and fragments of diamonds crushed by the stamp mills are not uncommon in the flumes and sluices. Most of the stones found within recent years have come from the vicinity of Placerville, Eldorado county. [ndiiinit. — Brown county, five — one of 2 carats, others very small. Morgan county, three — one of 3| carats, others very small. Kentucky. — Cabin Fiirk creek, Russell county, (jne. Michigan. — Dowagiac, Cass county, one of lOJ carats. Oil id. — Milford, Clermont county, one of 6 carats. Tennessee. — Koko creek, Tellico I'iver, Monroe county, several reported. Union Crossroads, Roane county, one of 3 carats.

Kohlsville, Washington county, one of 21 carats. Saukville, Ozau- kee county, one of 65 carats. Eagle, Waukesha county, one of 15|3 carats. Burlington, Racine county, one of 2^\ carats. The whole subject of the Indiana occurrence is fully described b}' the state geologist. Prof. W. S. Blatc.Vley,' in his annual report for 1902. The geological failures of the region are first treated with special reference to \Ctj distribution of the drift depo.sits in central Indiana. liiese have been known since 1860 to contain gold, and a large amount of local prospecting and panning has been carried on along the streams for years. The gold is found associate<:l with magnetic iron sand, menac- canite, and other heavy luinerals. It is in these aurifer- ous sands that diamonds have been found at intervals for some twenty-five years, but especiallj' of late. Some of the diamonds belong certainljr in the second, or later, drift, like most of those in Wisconsin; others found south of that line but within the margin of the older drift belong, perhajjs, to the older deposits in- stead of having l:)een washed out from the later beds and carried south by streams, as formerly supposed. The terms "earlier" and "later" are now frequentl}^ replaced by "Illinoian" and " A\'isconsin," and desig- nate the two glacial drifts, but these terms may be nusconceived as to their gcograi^hical signification and hence require explanation. The center of ice move- ment in the glacial era was determined some years ago by Canadian geologists as having traveled or shifted toward the east from the west. Of the two ice inva- sions that spread over the northern United States, the earlier is called by some geologists the "Illinoian," as having covered a large part of that state not reached by the later one; while the name "Wisconsin" is ap- plied to the later by Prof. T. C. Chamberlin, because it extended westward to a portion of that state not cov- ered by the earlier, and formed there what he terms the Wisconsin boundary, although its source was far east of the earlier drift, and it forms the main deposit of the Eastern states. Professor Blatchley's list comprises eight diamonds that he himself has seen, and seven more of which he has credible information. The earliest pul>lished men- tion of the occurrence of diamonds in Indiana was made by the late Prof. E. T. Cox, state geologist, in his annual report for 1878, page 116, although the well- known artist, Mr. Daniel Beard, of New York, owns a ' Gold and Diamonds in Indiana, by W. S. Blatchley. Twenty- seventh Annual Report of the Departinent of Geology and Natural Resources of Indiana, Indianapolis, 1902. 1046 MINES AND QUARRIES. fine diamond of about 2 carats found in Indiana be- fore tliat year.' Professor Cox mentions several dia- monds, of which this may be one. as found in the drift of Brown and Morgan counties, and I'efers to them with interest because of theii- evident transportation from a far northern source. Of the ei^-ht stones seen ))y Pro- fessor Blatchley, four are from the newer and four from the older drift, or at least from the area covered by it south of the margin of the newer. The list in detail is as follows: 1. The Stanley diamond, found in 1900, by Calvin Stanley, while panning for gold in Morgan county, on a bi'anchof Gold creek. Smiles northwest of Centerton, and 3 miles west of Brooklyn. It was found in the bed of the stream at the base of a clifi' of shale. The stoiV) was an octahedron weighing li carats, with a yellow tinge and a small black spot. It was purchased first by Mr. K. L. Eoyse. of Martinsville, Ind., and l:)y him sold to C. E. Nordyke, of Indianapolis, who had it cut into two stones in Cincinnati. These have a peculiar greenish j'ellow tint, and weigh respectively 1^ and lyV carats. 2. The Young diamond, found by a local gold hunter, Mr. W. W. Young, in IS'.iS, on Lick creek in Brown county, li miles south of Morgantown. It is an ob- long dodecahedron of Ifi carats, white with a yellow cast, and very clear and flawless. It is retained by the finder. 3. An elongated hexoctahedron, of pink color, but only one-eightli of a carat in weight. It was found, like the last, on Lick creek, by Mr. John Merriman, and now belongs to Mr. Nordyke, of Indianapolis. 4. A j-ellow hexoctahedron of three-sixteenths of a carat, found l)y Mr. Merriman on Lick creek. It is no^v owned by Mr. Royse. 5. A light brownish yellow hexoctahedron of five thirtj^-seconds of a carat, found and owned by Mr. Ko3^se. 6. A bluish rhombic dodecahedron, weighing eleven- sixteenths of a carat, found by Mr. Merriman on Gold creek, Morgan county, now also belonging to Mr. Royse. 7 and 8. These are pinkish crystals, neither of which exceeds one-eighth of a carat, found in Maj-, 1003, by Mr. Royse. They were taken from the tailings of sluice boxes on the farm of Doctor Cook, neai' Brey, in Moi'gan country. The first, and the last three, from Morgan county, are from the newer or Wisconsin drift, the others, from Brown county, are from the older or Illinoian area. Hnppli'ire^ (iiid rvhicn. — The sapphire, ruby, oriental topaz, oriental amethyst, and oileiital emerald are names given respectively to tiie transparent blue, red, yellow, purple, and green A'arieties of corundum, which is nearly pure alumina, AL,0,,. The colors of these minerals are ' This diamond, from facts that Mr. Heard lias y:iven the writer, must have been found as early as 1H26. ascribed to the presence of minute quantities of metallic oxides. Their specific gravity ranges from 3.97 to 4.0.5, and their hardness is 9. Rubies are found in Burma, Ceylon, and Siam. Sapphire also occurs in those coun- tries, as well as at the Simla pass in the Himalayas, and in Australia. The great hardness of corundum gives it a special value for polishing purposes, and the amount produced for such uses during 1903 has been treated under "Abra- sive materials.'' Although corundum is found in the crvstalline rocks along the Appalachian mountains from Massachusetts to northern Georgia, few gems of any special value ha^'c been found, except in the Cowee valley in North Carolina, where true rubies are ob- tained to some extent, although mining has ceased for a few years past. Other ts^'i^ which these gems are found exist in Mont;,^ ^ ^pSj^phires of the finest quality are now mined in *" '^ ^'''wtelch. and others of much beauty are found at o''^'' ■'; points iu the .same state. Until wttiTT'n^'S'few \'ears, these gems had been found only occasion!tily in the United States — nearly all of them in North Carolina — and were principally cut from small transparent portions of the colored corundums that were otherwise more or less opaque. Corun- dum is rained in that state extensively as an abrasive material, and ruby and sapphire are simply transparent varieties of it. The ^Montana gems began to attract notice about 1869, and for some j'ears they were col- lected abundantly from the bars of the upper Missouri east of Helena; these were of varied and often beau- tiful tints of pink, blue, green, and intervening shades, but rarely of the deep colors in favor for jewelry. The latter, the rich blue sapphires equal to those of India, have since been found at Yogo gulch, in Fergus county, and active work in mining them from the rock has been carried on for several years l)y the New Mine Sapphire Syndicate and the Burke and Sweeney Company. Two other important localities in Montana are at Rock creek, in Granite county, and Dry Cottonwood creek, in Deerlodge county, worked by the American Gem Syn- dicate Company. The former of these yields a won- derful variety of colors, often very beautiful, but few that have the deep shades most valued in the gem mar- ket. No locality in the world has shown such variety of tints in sapphires — pink, reddish brown, brown, yel- low, green, etc., with occasionally a ruby of the paler typo of Ceylon. Gems of considerable value have been annually mined at Yogo gulch for several years past. Fine ,sapi:jjiires of the " cornflower" and " velvet" blue of the best oriental stones have been obtained, weigh- ing as much as 3 carats, and a few as high as 5 and even 7 carats, after cutting. Besides those used for setting, large (juantities of small ones from both these localities have found ready sale for watch jewels and liearings; indeed, more have been sold for this purpose than for gems. PRECIOUS STONES. 1047 True rubies have been found, and to some extent, mined, in the Cowee valley, Macon county, N. C. Some of them have the rich and peculiar " pig-eon\s-blood " color of the finest rubies from Burma, but the crystals are small or imperfect, and the yield thus far has been quite limited. The operations were conducted l)y the American Prospecting- and ]\lining- Company. Emerald. — True emeralds, suitable for cutting and set- ting, can hardly be said to be found in the United States. It is true that large and very tine crystals of emerald were obtained at Stonj'point, Alexander count}', N. C, in 1877; but these, although valuable and beautiful as specimens, were not clear enough to cut into gems. More recently a locality has been opened at Cral^troe, Haj'wood county, in the same state, where small and handsome emerald crystals, both translucent and opaque, occur thickly in the white feldspar and quartz of a vein of pegmatite (coarse feldspathic granite). This green and white mixture is very pleasing, and as the three minerals have nearly the same degree of hardness, the whole can be cut and polished together, making a novel and beautiful ornamental stone. Pieces are cut e)i cahochon, i. e., rounded, not faceted, showing sections of the emerald crj^stals in different directions in the white mass. This material has been introduced into ornamental and minor jewel work under the name of "emerald matrix," b}^ the American Gem Company. Beryl. — Ber}^ is essentiall}' the same mineral as emerald, though of paler shades and much less esteemed. Fine transparent beryls, however, are choice gem stones, and several varieties of them are found in the United States. Among these are emerald beryls, of rich light-green shades; aquamarines, faintly tinged with green; golden beryls, of a rich yellow; blue beryls, sometimes almost as beautiful as pale sapphifes; and rose beryls, of light-pink color. Some very fine gems have been cut from crystals of these kinds, espe- cially from Topsham, Me., in the quarries of the Tren- ton Flint and Spar Company. Other line gems come from Comiecticut, North Carolina, and Colorado. In North Carolina, near Sprucepine post office, mauj' fine beryls — some of the richest blue color ever found — have been mined by the American Gem Company. The finest and largest aquamarine known is from Stoneham, Me. Golden beryls of much beauty have been cut from material mined at Merryall, in Litchfield county. Conn. Green and blue beryls have been found in North Caro- lina, and aquamarines at Mt. Antero, Colo. The dis- coveries of line gem material are, however, not frequent nor in large amount, so that there is no systematic min- ing or regular production. Tcqjaz. — Topaz is a fluosilicate of alumina and crystal- lizes in rhombic prisms with a hardness of S. The true topaz occurs but sparingly in the United States, although here and there it has been found fine enough to yield choice cut gems. Still, as with man}' other gem minerals, there is no locality that furnishes any steady supply. Within recent years a few white topazes have been obtained at the Stoneham, Me., and Chatham, N. H., localities; also at Cheyenne mountain, Pikes Peak, and at Nathrop, Colo. They are gener- ally sherrjf-colored at the former localities, in crystals weighing up to 3 ounces each; at Nathrop in smaller l)rilliant cr5'stals. Very recently a number of topaz crystals have been obtained near Ramona, San Diego count}'^, Cal. The crystals vary from quite small ones of great brilliancy up to 1 or 2 inches long and half that diameter. Most of them are perfectly colorless, but some have the pale blue or greenish blue of the topazes from Sarapulka, in the Urals. The larger crj'stals are somewhat dull externally, but almost all are clear within and would cut into handsome gems. Garnet. — The name garnet is used for a well-defined group of minerals very closely related in both chemical and physical properties. Thej' are complex silicates of alumina, with varying amounts of lime, magnesia, iron, manganese, and other metallic oxides, which, by their presence in different proportions and combina- tions, impart various colors to the compound. All the garnets crj'stallize in the isometric s\'stem. Several of the varieties are richl}^ colored, and when transpar- ent are favorite gem stones, though not of the highest value. The kinds chiefly used in jewelry are those known as precious garnet, or almandine, Bohemian garnet, or pyrope, and manganese garnet, or spessartite. The two former present deep crimson shades, and the latter is of an orange-red or light red-brown color. These are all found in the United States, but there is no regular production, save to some extent of pj-rope, in Arizona and New Mexico, and of a beautiful light purple-red garnet known as rhodonite, an intermediate variety between pj'rope and almandine, in Macon count}', N. C. This latter is among the discoveries of the last decade, having attracted attention and been more or less mined since 1897, and the stones produced have been cut and sold as rather novel American gems. The locality is in the Cowee valley, where the rubj' corundums be- fore alluded to have been found. The garnets occur chiefly in the valley of Masons branch, a small stream flowing from Lisle Knob, a spur of the Cowee moun- tains. All are found in rather small pieces, but their color is a beautiful light red, and their luster when cut is remarkably brilliant. Thej' were at tirst taken for almandine, and so reported, but anal^^sis shows that their composition lies between that varietj' and pj-rope, and hence they were given the separate name of rhodo- nite (from the Greek rluxlon, a rose). In the A'ears 1900 and 1 901 the output of these garnets amounted to $20,000 and $21,001), respectively. It has since fallen off' some- what, but work is actively carried on, and large pieces have been obtained, up to 43 and even .59 carats. Pja-ope garnets of flue quality are found in several 1048 MINKS AND QUARRIES. localities in New Mexico and Arizona, and are fre- quently miscalled Arizona rubies. The principal lo- cality in New Mexico is on the Navajo Indian reserva- tion, and the finest large specimen from there is the property of Mr. W. T. Kaufman, of Marquette, Mich. It is more than half an inch in diameter, weighs llA carats, and has a magnificent red color, equal to any garnet that the writer has seen from any locality. They are also found at some places in northern Arizona, and one of the finest, from near Fort Defiance, was figured by the writer several 3'ears ago.' They occur loose in the soil, on or near the surface, and are gathered by Indians, soldiers, and cowboys, principally from around ant hills and scorpion holes, where they are brought up and thrown out by the insects. Their source is doubt- less in peridotite rocks, from which they are weathered out in the decomposition of the outcrops. In the j'ears since 1S96 the annual sales have been estimated at from $1,000 to 12,000. Spessartite (manganese garnet) was found in mag- nificent specimens twenty years ago in the albite ndne at Amelia Court House, Va., and splendid gems were cut from these. But unfortunately the mine has been closed and abandoned for years past, and one of the finest localities for American gems has thus ceased j'ielding. Verj- recently beautiful crystals have been found at Ramoua, in San Diego county, Cal. Some are 15 millimeters in diameter or more, of a rich orange- brown color, and the smaller crystals exceedingly clear and brilliant. This may prove to be a source of choice gem material, although as yet the amount of it present has not been ascertained. Many other varieties of garnet are known to exist in various parts of the country, and some gems have been cut from them at times, but there is no regidar pro- duction. Several kinds are reported in Tulare countv, Cal., and one of great rarity' and beauty at Carrville, Trinity county, in the same state. This is the emerald- green chrome garnet, known as uvarovite, whidi fur- nishes beautiful gems when in crystals of anv size. This was reported in V.KH) as found in small crystals, lining cavities in chT'ome iron, very richly colored and brilliant, but none of the crvstals was more than 3 mil- limeters in diameter, and no further exploration seems to have been made since. To/mnal/'/ie. — Tourmaline belongs to the rhombolie- dral system of crystallization, occurring in prishis, the sides of which are generallv striated and channeled. The transparent variety is of a hardness of 7.5, its spe- cific gravity ranges from 3 to .3.25, and in composition it is a very complex silicate of alumina. Many different ' Gems and Precioua Stonua of North America, 1892, Plate III fig. A. colors are found, ranging all the way from a colorless variety through red, green, blue, and brown, to black. These difi'erences in color are chiefly due to the varying amounts of manganese and iron present. The gem is dichroitic; thus when viewed through the side it may be a transparent green, but either opaque or j^ellow- green when viewed endwise of the prism. Tourmaline was but little known in jewelr^^ten years ago, although some very beautiful gems had been cut from the transparent red, green, and blue crystals ob- tained at Paris Hill, Me., and Haddam Neck, Conn. Some mining had been done at these places, and manj^ splendid specimens obtained. But within a few years past, wonderful discoveries of gem tourmaline have been made in southern California, at Pala and Mesa Grande, in San Diego county, and in the San Jacinto mountains in Riverside county. The crj-sfcals found at these localities are of great size and beauty, and gems have been cut from them in abundance. A single col- lection of these crystals has been valued at §510,000. The prevailing colors are pink, salmon, and red, all in very rich shades, also fine green and blue, though less frequentl}' in, these colors than those found at Mt. Mica and other localities near Paris, Me. Tourmaline is peculiar in that it often presents two or three differ- ent and even contrasting colors in the same crystal, which sometimes shade into each other, but often pre- sent a sharp line of contact. Advantage has been taken of this feature, which is marked in the California crvs- tals, to produce in jewelry the novelty of parti-colored gems. Beautiful cut stones may now be seen that are half red and half green, or showing other similar con- trasts. Many of the larger stones arc somewhat flawed ; these are often cut v hiddenite or any other specimens of spodumene examined. Doctor Baskerville proposed for it the name of "Kunzite.'" Cal/forvitc. — Calif ornite (vesuvianite) ° a mineral which i^romises to be a notable addition to the increas- ing list of semiprecious or ornamental stones found in the United States, has recently been discovered in Cali- fornia. This is not a new mineral species, jjroperh', but a compact massive variety of vesuvianite (idocrase). It was first announced in the report of the United States Geological Survey for 1901,' by the writer, as having been found by Dr. A. E. Heighway, on the South Fork of Indian creek, 12 miles from Happy Camp and 90 miles ''The following articles treat of the new mineral: Science, Vol. XVI, August 28, 190.3.

Here a hard and liandsome stone, varying in color from olive to almo.st grass-g-reen, and taliiug a tine polish, outcrops for some 200 feet along a hillside about 100 feet above the creek, and large masses have fallen into the bed of the creek. At first it was supposed to be jade (neph- rite), but upon analysis proved to be vesuvianite. The fallen pieces were in some cases as much as 5 feet square and 2 feet thick, of excellent cpiality for polishing, and of varying shades of light to dark green. The associ- ated rock is precious serpentine. A very similar mineral was discovered some years ago at one or two places in the Alps, and, like this, was at tirst described as jade, but on analysis proved to he massive vesuvianite. The likeness to green jade is very marked in both these and the California mineral, and the mistake is not sui'prising. The following analysis was made through Prof. F. W. Clarke, chief chemist of the United States Geological Survey, by Mr. George Steigei-, in the spring of 1903: Aaalysi,? of resurkuiite from Sifkii/ou county, Ciilifoniin. SiO, .S.5. 8.5 ALO3 18.35 Cab - .33. .51 FeA 1-67 FeO 0. 39 MgO - 5. 43 MnO 0. 05 The anal3'sis is essentially that of a normal vesuvian- ite, though the percentage of water is unusually high. The lime and the iron are below the average, and the titanium and phosphorus are exceptional occurrences. The mineral is compact, extremely tough, and readily takes a high polish, quite as beautiful as that of neph- rite (jade), with which it was at first confounded. The hardness is 6.5 and the speciiic gravity (from two determinations) is 3.286. The luster is vitreous, often inclining to resinous, and the streak is white. The color is a yellow leek-green, with inclusions of a darker green, which are generallj' more translucent than the surrounding mass. This interesting mineral exists in large quantity, and could be cut into a variety of ornaments, in the same way as jade, nephrite, and chrysoprase. It is a form of vesuvianite distinctive enough to receive a special vari- ety name, which, if appropriate and euphonious, would undoubtedly aid the sale of the stone in the arts. The name of ' ' Calif ornite '' has been proposed for it. The discovery of what appears to be the same min- eral has I'ccently been announced from two other local- ities in California quite r(^mote from the tirst. One of these was reported by that indefatigable prospector, Mr. M. Braverman, of V^isalia, as existing in Burrough, in Fresno count}', a mile and a half from Hawkins scho\tent for making orna- ments and souvenirs that are sold to \'isitors in the region of its occurrence — Pipestone county, in south- western Minnesota. It is not really a detinite mineral species, but essentially an indurated red clay. Among the Indians it has long been held almost sacred as the material for making "pipes of peace." The principal locality Avhere it is found was, and still is. visited by Indians from all parts of the country to obtain it for that purpose, and is still regarded by them as a kind of inviolable spot, where all have the right to come. The United States Government has very properly set apart the land on which the Cjuarry exists as a small reserva- tion, to secure this free right of access to all Indians forever. It is jealously guarded by the native tribes, and it is seldom that large pieces can Ije secured by white men; hence the supply is rather limited and is likely to remain so. The only large object ever made from this material was a mantelpiece, carved by an In- dian artist, with designs from Hiawatha, which was ex- hiljited in the Minnesota building at the Pan-American Exposition of 1901. It had been shown previously at the Columbian Exposition in 1803, and is now in the courthouse at Pipestone, ]Minn., in the room occupied by the Women's Historical Society, to which organiza- tion it belongs. The sale of ornaments and souvenirs made of catlinite is estimated at about $2,000 annually, for some years past. Fluorspar {IJIinoia). — The old and celebrated "Shaw- neetown" region in southern Illinois has lately been jaelding fluorite of remarkable beauty. In a lot of specimens recentU' sent to the writer for examination were cleavage pieces of much beauty from sevei-al of these localities, notably the Emjiire mines and Cave- in-Rock. From the former were large cleavages of rich reddish purple, and of the peculiar sea-blue of that region; in one case the general color was of the latter kind, clouded at points with the former— like the tint of a lilue Alabashka topaz with included clouds of Uralian amethyst. Both the purple and the sea- blue varieties at times pass into almost colorless tluor. That received from Cave-in-Rock presents an octahedral cleavage, perfectly transparent and of amber yellow. A cubical crystal received from Rosiclare was pale bluish, becoming nearly colorless. QUARTZ MINERALS. Iiocl-cri/KfdI. — Rock crystal is a \'ariety of transparent colorless quartz, composed of nearly pure silica. While it is not rare as a mineral, yet it is sddom found in masses of large size. When so found, i]owe\<'r, it is \'aluable for use in the ornamental arts. (_)iie oi- two localities in the Al))s, that have been known and worked from Roman times, tliough vei'y di Hicult and perilous of access, ha\'e furnished material for all the oljjects in European palaces and nmseums which ha\'e been carvc^d fi'om this suljstauce. In Japan, too, large crystals were formerly obtained, from which were made the polished balls, so nuich i)rized Ijy the natives, and afterwards by foreign- ers, who have now almost drained the country of them by purchase. The main supply in recent years has been derived from Madagascar and Brazil. Within the last decade very tine rock-crystal masses have been detained in the United States, especially in California. An important discovery was made in 1891-1)2 by Mr. James lUackiston, near Placeryille, Eldorado county. Here, in a partly decomposed quartz vein, were found crystals ranging from small sizes up to masses of 80 or 90 pounds in weight. Some are clear and Hawless, while others have the peculiar and lieauti- ful marking known as " included phantoms." This fea- ture has been caused by successive deposits, and is shown by the appearance of several crystals of identical form, one within another, each being outlined by a thin coat- ing of some other mineral, which delicately colors the otherwise transparent quartz. These coatings in the I California crystals are of rich green chlorite. Similar chlorite phantoms in clear quartz have since been found also in San Bernardino county, in the mountains of that name. The most remarkable discover}' of quartz in Califor- nia, however, was made in 1897, in Calaveras countj', at the old (Treen Mountain mine, in Chile gulch, near Mokelumne Hill. Here, in one of the ancient ri\-er channels tilled with auriferous gravel and covered by an overflow of lava — a formation characteristic of that ' region of the state — was found a quantity of enormous I quartz crystals, embedded in the old gravel. It is j claimed that 12 tons were taken out in the years 1897 and 1898. One giant crj'stal, surrounded by an attached cluster of smaller ones, weighed over a ton. A num- ber of the finest specimens were sent to New York, and splendid balls wei-e cut from them hj machinery espe- cially constructed for the purpose. Two of these balls were a little over 7 inches across, but they are not absolutely flawless. A third, 5i- inches in diameter, without a blemish, was valued at $3,000. The latter, and one of the other two, are in the Tifi'any-Morgau collection at the American Museum of Natural Historj' in New York; the other is in the Museum of the Jardin 1054 MINES AND QUARRIES. des Plantes at Paris, with the collection of American gem minerals that was prepared for the Pan-American Exposition of 1901. So far as the gravel deposit was explored, the crystals appeared to 1)6 strewn through it, and it would seem to contain a large amount of valuable material, although no work has been done there since 1898. Other local- ities in California where cr3'stals weighing several pounds have been found are Drum valle}-. Three- rivers, and Yokohl. in the neighborhood of Visalia, in Tulare countJ^ In Oregon, large transparent masses have been found near Bay City, but no particulars of their occurrence are given. Some tine rock crystal occurs in North Carolina, in Chestnut Hill township, Ashe county, on a spur of Phoenix mountain, near Long Shoal creek. Here, at two or three spots not far apart, were found pieces up to 5(» pounds in weight, and two very large crystals, of 188 and 285 pounds, respectively. A crystal ball, 5 inches in diameter, and a number of art olijects, all of American workmanship, made frona this material, were shown at the Columbian Exposition at Chicago in 1898. Another find in North Carolina was reported in 1896, from Elkin, in Surry countv, hy Mr. R. M. Chatham, who described crystals up to 10 pounds in weight. Some large crystals are also known to have been found in South C'arolina, and it is probable that much rock crystal adapted for use in the arts, exists in the moun- tain regions of the South. Colorado has furnished some fine material, especiallj' that from ]Mt. Antero, Chafl'ee county. A polished ball, 6 inches in diameter, from the summit of this mountain was exhibited at the Columbian Exposition. A find of considerable (juantity was reported in 1896, at Cheyenne pass, Wyoming, about IS miles west of Cheyenne city, but no development at that point ap- pears to have been undertaken. The quartz crystals of Hot Springs, Ark., have been known for many years and furnish a constant source of business to the farmers of the surnnuiding country, who collect them and bring them in by the wagon load to sell to local dealers and to tourists. Th(>se crystals are not large enough to yield art material, but they are beautiful as specimens, eithei' as single crystals or more frequently- in groups. It is (estimated that in the 3'ear 1896 no less than 15,000 pounds were gathered in Mont- gomerv. Saline, and Garland counties and sold in the city of Hot Springs for $5,000. i'lilorcd viirietieK. — Among the colored varieties, Vjesides amethyst, of cr3'stalline quartz suitable for use as precious or semiprecious stones, two are important — smoky quartz and rose quartz. Both are fcjund at various points in thr United States and have been mined more f)r less during the past ten vears, although there is no laig'c or contiMUf)Us suj)i)ly. Siiwky quartz. — The most noted place in which smoky fiuartz occurs is at and near Pikes Peak, Colo., where it is abundant in fine crvstals, in a coarse granite, as- sociated with the beautiful crystals of green feldspar (amazon stone), for which that locality is famous. It is found also at Mt. Antero, in Colorado, where the smoky quartz obtained in 1891 yielded one of the finest faceted stones in the world, measuring 3^ inches in length. It was cut and exhibited at the Columbian Exposition. Much of the material from Pikes Peak is sent abroad for cutting, and returned to be sold at Denver and Colorado Springs, Colo., at Hot Springs, Ark., and other interior resorts, as jewelry to tourists. The annual sales amount to about |10,0O0, three-fourths of which is for cut stones and one-fourth for specimens. Large crystals, up to 4 and 5 inches in diameter, have been collected at Brandy creek, in Lemlii county, Idaho. They have been found, too, at Three Mile Gulch, near Helena, ]\lont., and a gigantic cr3'stal, nearly 2 feet long and weighing 93J- pounds, was found in 190(J. on Clear creek, Jeft'erson county, Mont., by Mr. E. P. Chisolm. Crvstals have also been reported at points in South Dakota. A considerable quantitv occurs in connection with the colored tourmalines in southern California, both at the San Jacinto mine in Riverside county and those at ^lesa Grande in San Diego county. In the East very fine smoky quartz has been found in Maine and in North Carolina, as well as at some other points. I'he specimens from Maine are particularly beautiful. Ciystals of 40 pounds in weight were re- ported in 1896, b3' IMr. R. M. Chatham, from a locality near Elkin, in Surrv county, N. C. , and it was alread v well known in the neighboring counties of Alexander. Burke, and Iredell. In Connecticut, at New Milford, some 200 pounds of smokv (juartz, worth over §100, was taken out in 1898. But the most valuable yield has been in Oxford comity, Me., where as much as 3 tons of crvs- tals were reported by Mr. T. E. Lamb, of Portland, as mined in 1897, on Mt. Apatite. Much has been taken out since, including one perfect crystal 12 pounds in weight, and a polished ball 3 inches in diameter has been cut from material obtained here. BtiHi' quartz. — The delicate pink variety of quartz known as rose quartz has long been obtained at several ]K)ints in New England, especially at Albany, Stow, and Paris, in ^Maine; at Southbury, in Conni-cticut; also at Bedford, in AVestchester county, N. Y. Though a beautiful material, it had been little used in the arts or as a gem until ((uite recently, when it was tried with some success. In general, and particularly in the case of the specimens from the localities in ^Maine, the tint vari(>s gnnitly from an almost colorless varietv. some- times opalescent, to pale pink, salmon, and deej) rose. "W hen cut into dou)il(> ciilinrlioiis. or balls, it sometimes shows the asteria efiect, 1 i ke a star sapph ire. Very fine, rich-colored ])ieces, partly opalescent and in size up to PRECIOUS STONES. 1055 4 or 5 inches in diameter, liave ))een obtained at Kound mountain, near Albany, Me., and a ball of 2i incheK across, with other cut objects from this locality, wore shown at the Columbian Exposition. Rose quartz occurs also at Acworth, N. II., in the celebrated beryl locality, and a large lilock of tliis mate- rial, some live feet square by half that thickness, has been set up as a monument in Franklin, N. II. , to the late Walter Aiken, of that place. The mass is somewhat fissured, however, and rose quartz is liable to fade in the sunlight, so that neither in texture nor in color is it adapted for monuments or other use out of doors. In 18i:>4: the occurrence of rose quartz in Iredell and Cabarrus counties, N. C, was amiounced b}^ Prof. T. K. Brunner. In 1896, 50 tons of it were mined at Theresa, in Jefl'erson count}', N. Y., and its presence was noted in Colorado by Mr. E. H. Saltiel, at the headwaters of Currant creek, in Park county. In the same ye&v Messrs. M. Braverman and W. H. Smith described several places where it occurred in the neighborhood of Visalia, in Tulare county, Cal., especiallj' on the Yokohl river, where about $1.!)0 worth was then taken out. It exists in some quantity, and of excellent color, at Yokohl and Threerivers, in the same county, and probaldy at other points in that section. By far the most extensive occurrence, however, is in the Black Hills of South Dakota. Specimens were first brought in by Prof. W. P. Jenncy on his exploring ex- pedition in 1876, and a fine display of it was made in the South Dakota building at the Columbian Exjiosition of 1893. The exact locality is near French creek, 6 miles east of Custer, in the county of that name. Here it exists in great quantity and of fine quality, outcrop- ping along a ledge for 5(M> feet in a vein varying in thickness from a few feet up to 00. The color, as usual, ranges through many shades, from faint jjink or e\en white, to the tint of a ripe watermelon, and in places alters completely" within a few inches. Contrary to the general opinion, there is no evidence of its fading by exposure to light, for outside portions, and even rolled bowlders, show in some cases a fine deep coloring. Thus far the mining has fjeen carried on mainly by hand, much in the nature of quarrying. About three-fourths of the stone removed is rejected as lacking color; the rest is sorted and sold according to size and color, chieflj^ to dealers and collectors, at prices ranging from 5 to 25 cents a pound. One mass weighing over a ton was re- cently sold to be cut into table tops, 30 by 36 inches in size, which were sent to Paris to fill an order. The production reported to the United States Geological SurvcA' amounted to 4 tons in 1902. Amdhyxt. — Amethyst is a variety of quartz of a deep purple or bluish violet color, shading almost to pink. Like ordinar}- quartz, it is composed of silica, and the coloring is due to the presence of oxides of mano-anese and iron. Its hardness is about 7, and its specific gravity is slightly above 2.65. Fine gem material has been found in the United States, though nowhere is it mined with any regularity. The localities from which the finest specimens come are in Maine, Pennsylvania, North Carolina, southern Virginia, and northeastern Georgia, and several disco\'- eries have been made recenlly in the West. The main develojjments within the last ten years are the following: Deer Hill and Stow, in Maine, were noted localities some time ago, but have not jdelded much lately. At Denmark, however, in the same state, Mr. G. R. Howe obtained many fine crystals in 1894, and had a number of gems cut that were very richly colored — equal to any from the Ural mountains. Another old locality was Upper Providence town- ship, in Delaware countj'. Pa. Here, in 1894, a large amount of ameth^-st w'as obtained that j'ielded gems of the finest quality, one of which was of 33 carats; and another, still larger, is in the Lea collection in the National Museum at Washington. Virginia has only recently come into notice as a pos- sible source of amethyst production. In 1896 its occur- rence, in beautiful cr3'stals, was announced at two points in Goochland county, bj- Mr. G. L. Chase, and also near Lovingston, Nelson count}', by Mr. Benjamin Dillon. In 1902 a promising locality was discovered and opened in Amherst county, near Lowesville. North Carolina has for years yielded more or less ameth3'st at various points in Burke, Catawba, Iredell, Lincoln, Wake, and other counties. In 19<»1 mining was begun in Macon county, on Tesanty creek, where a large vein traversing a decomposed granite had been exposed b}' a landslide. Several thousand dollars' worth of material was taken out, as rich and fine in quality as any ever found in the United States. Amethyst of excellent quality has been occasionally found in Anderson county, S. C. , in Hall and Rabun counties, Ga., and at Amethyst mountain, in Gillespie county, Texas. The western sources of production are chiefly in Montana. In 1895 a cr3'stal weighing 12 pounds was found at Granite, and in 1900 remarkable discoveries were made in Jefl'erson county, some 22 miles south- east of Butte, by Mr. A. P. Pohndorf . Here amethyst occurs in fine crystals, curiousU mingled with quartz both colorless and smokv. Crystals of black tourma- Ime so penetrate the quartz as to render it opaque. The amethj^st itself is free from these inclusions, though sometimes it forms parts even of the same crystals. In Colorado, amethyst is reported from Cripple Creek and from localities in Park and Mineral counties, but no special data have been given as to these occurrences. Good material has been brought from two or three points in Alaska, but there has been no development as j'et. Quarts pchhjrx. — Natural rolled pebbles of quartz, of various colors, are often beautiful, sufliciently so at times to lie iipplied to some uses in the arts or 1056 MINES AND QUARRIES. for cheap jewelry. At many points alony- the A thin- tic coast, visitors to the seaside resorts o-ather peb- bles of attractive aspect, especially those of colorless transparent quartz, and sometimes have them cut as souvenirs. These are the so-t'alled (Jape May dia- monds, and there is quite an industry at many resorts in g-atherintr pelibles to cut for u-ems, seals, etc. A good deal of fraud is also practiced upon visitors. all manner of ornaments being- sold as material found in the vicinity. At Narragansett Pier, K. I., some local dealers and lapidaries have been known to sell foreign-cut quartz, cairngorm stone, topaz, erocid- olite, Ceyloneso moonstone, and e^en glass as stones from the beach. In some cases pebltles foiuid ])v visi- tors and entrusted to lapidaries for cutting have been replaced l)v cut stones import(>d from Bohemia, Olden- burg, and the Jura, where cutting is done on such a large scale and at such low wages that the stones can be brought here at one-tenth of the cost of cutting, the material itself, in the case of quartz, having l.)ut small value. The annual proceeds from the sale of cut stones, and the money expended in cutting them at these and other resorts throughout the country, may amount to $20,000 or more a vear, and the sale of specimens to a like sum. Another ingenious fraud has been practiced at Hot Springs, Ark. , where clear, rolled pebbles of colorless quartz, found on the 1)anks of the Ouachita river, are in special demand, being more valued for cutting than the crystals of the vicinity, because of a mistaken idea that they will cut into clearer gems. Fine pebbles of this kind are scarce, and so they have been artificially imitated liy putting a number of crystals into a box, which is kept revolving by waterpower. In a few daj's mutual attrition has rolled and roughened the crystals into beautiful pelibles — so beautiful, indeed, that an expert can distinguish them from tiie real ones by their more perfect whiteness of surface. Along the coast of California and Oregon there are various localities where many verv attractive pi'bbles of chalcedony, agate, etc., are found. The principal beaches are at Crescent City, at the northern extremity of California; Pescadero, some 28 miles west of San Jose; and Kedondo, a few miles south of Los Angeles. These pebT)les are very abundant and in great variety, and are much sought by visitors. Many are put up and sold in bottles of water, to preserve their bright colors and markings and their transluconcy; and many are drilled and strung to make chains and similar fancy ornaments. Some of those at Pescadero are little hol- low geodes of chalcedony, occasionally an inch long, inclosing a liquid with a mo\'ing bubble. These little natural-sealed flasks are found also on the beach at Tampa, Florida. There are likewise many inland localities — several in California, cspeciallv on the shoi'c of Lake Tahoe; also in Colorado, and the beaches of Lake Superior — long famous for their agate pebbles, chlorastrolites, etc. One special use of quartz pebbles in ornamental art work should lie here alluded to. On Plum Island, in Long Island sound, there are quantities of pebbles of colored quartz — amethystine, smoky, yellow, etc. — brought down )iy glacial action from the crystalline rocks of Connecticut and rolled and rounded on the island beach. These have been used in a very ettecti\'e manner, in the same way as rounded pieces of colored glass, Ijy leading them for screens, shades, etc., to show their tints by transmitted light. This application was introduced about ISHT, by Mr. Louis C. Tiflfany, of New York.' A(iras<'. — Another semiprecious stone which has been developed in the United States within the past decade is chrysoprase, a chalcedony of a light green color, caused l.)y the presence of oxide of nickel. This stone has been highly valued for centuries, but is of rare occurrence, and most of that used in jewelry and in the arts has been obtained from Silesia. Its existence in North America had been recognized at some points before, but the onl}- promising locality was at Riddles, 30223—04 67 Douglas county, Oreg. Mr. George W. Smith, a sur- veyor, obtained specimens in Tulare county, Cal., as far back as 1878. These he sul)mitted to experts, who pronounced them to lie true chrysoprase. The first who positively identihed them as such, by actual deter- mination of the nickel oxide, was Mr. M. Braverman, of Visalia, Tulare county, who is well known for his enthusiasm in locating and collecting California min- erals. From that time specimens were gathered and sent quite widely to nuiseums and cabinets; but not for some 3'ears was its commercial value appreciated. When that became known, systematic development was attempted, the neighborhood was prospected, and other occurrences discovered, so that now there are not fewer than five localities in Tulare county where chrysojirase is known to occur. The first of these to be discovered was the one at Venice Hill, 12 miles northeast of Visalia; the others are on Stokes mountain, on the Tule river, on Deer creek, and at Lindsay, 16 miles south of Visalia. Mr. Braverman has been active in the search for these localities, and has presented to the California State Mining Bureau a very fine specimen from the last-named place. The veins which it forms are of no great thickness, and much of the material is flawed and cracked, or too pale to be valuable. Still a large quantity of fine chrysoprase has been obtained and cut, from these several localities, especially the last two and the first. The total production for several years did not much exceed $100 annually, but since a new company took up systematic work two years ago the yield rose to $1,500 in 1901, and $1,5.000 in 1902. Most of the material is cut into squares, ovals, etc., for rings and studs, and into small pieces of various shapes for inlaying as mosaic. Within the past year a promising locality has been discovered in North Carolina, at Morganhill, in Bun- combe country, some 16 miles from Asheville. Here it occurs in several parallel seams or veins quite near to each other; the color is pale at the surface, but becomes deeper below. No extensive work has j'et been done here, although some very rich green material has been cut and placed on the market, and the outlook is favor- able. 2fosn iigate. — The name "moss agate" is applied to a variety of translucent chalcedony, usually nearlj- col- orless, that is penetrated by minute branching or "dendritic" (tree-like) crystallizations of oxide of manganese or of iron, the former black, the latter brown or reddish. It has long lieen a favorite semi- precious stone in Europe and the East, but large pieces are rai'e. Small rounded nodules of it are abundant at various places in the West, particularly in Wyoming. In 1893 large masses were found near Hartville,Wyo., occurring in a vein 8 or 10 inches thick in limestone. Slabs of 2 or 3 feet in length could be taken out, accord- 1058 MINKS AND QUARRIES. ing to Mr. H. A. Crane, of Hartville, who described its occurrence, and tal)le tops made of it were shown in the AVyomino- section of the World's Colun]])ian Expo- sition at Chicago. The translucent white slalis. with moss-like markings in black, are verv beautiful. Two other localities in which fine moss agate has been found are reported in Wj'oming, one 47 miles and the other 75 miles northwest of Chej^enne. No important developments, however, appear to have been made at these points. Table 4.— DETAILED SUMMARY: 1902.

Bv .I08EPH Hyde Pkatt. Talc and .soapstoiie havo assumed a very important place amono- the minor mineral.s, and iu respect to the value of the production are near the head. This is due not so much to the variety of uses to Avhich they are put as to the very remarkable growth in the utiliza- tion of talc in the manufacture of paper, for nearly two-thirds of the value of the production in i'..l()2 was used for this purpose. Statistics for talc and soapstone include a small production of serpentine and the pro- duction of pyrophyllite, lioth of which are mined and used for the same piu'poses as those for which talc is emploved. In treating the statistics of the talc and soapstone mining industry it is necessary to include aiso the statistics of the. manufacturing processes wdiich are conducted at the mines under the same management, as the financial and other details are inseparable. This method has been customary since the census of bSGO, which was the first census to give statistics for this industrv. Table 1. _'ninparaiirf .■niiniiinry: ISOO tu 1903.

The industrv, as will be seen by the table, increased from a product in 1860 valued at $27,60(1 to one in 1902 valued at !?1,1S,S,167. From 1870 to 1880 there was a falling otf in value of $67,720, although there were 5 more mines or establishments in operation and lO-i more emploj-ees engaged in the work. This prol)- abh" can be accounted for by the fact that a number of new properties were being opened and developed, and this development required a large increase in the num- Ijer of enii)loj'ees without resulting iu production for the current year. Only the statistics for New York and North Carolina can be given separately, as there were not more than 2 producers in any of the other states. There were 20 mines in operation in the United States during 1902, of which 6 were in North Carolina; -1 in New York; 2 each in Maryland, Pennsylvania, and Virginia; and 1 each in California, Georgia, Alassachusetts, and New Jer.sey. Thirteen mines were rei:)orted idle — 1 each in California, Maryland, Massachusetts, North Carolina, and Ohio; 2 each in New Hampshire and Virginia; and i in Georgia.

The capital stock and funded debt of the i New York companies constituted 79.5 per cent of the total. The par value of the capital stock issued was 90.9 per cent of the total par value authorized. The bonded indebtedness was s.4 per cent of the capital stock and funded debt. The dividends paid amounted to 1.3 per cent of the total stock issued and 5.1 per cent of the total stock on which they were declared. Sixty-five per cent of the total amount paid in dividends was declared on preferred stock and 35 per cent on common. Of the total divi- dends 73.7 per cent was paid on the stock of the New York mines and 26.3 per cent on that of the mines in Virginia. Employee^ and wages. — In considering the question of employees and wages, it is to be observed that the talc and soapstone industry is a composite one of min- ing and manufacturing. There arc two principal kinds of manufacture: (1) The grinding of talc into tiour, after which it is packed in bags preparatory to ship- ment, and (2) the sawing and finishing of soapstone into slabs, mantelpieces, laundrj' tubs, etc. Thus it can readilj' be seen that more emplo^-ees are required, in proportion to the tonnage of the mineral rained, in an establishment where the higher grades of manufactured articles are made than in a plant where the mined talc is merely ground. This will explain the large number of employees in proportion to the tonnage in "'all other states," because in these the soapstone mined is largely converted into manufactured articles, this being espe- cially true of Virginia. The number of salaried employees was 75, or 8.9 per cent of the aggregate average number of all employees, which was 846, and the}- received in salaries $03,713, or 18.6 per cent of the total salaries and wages, which amounted to $312,796. The number of wage-earners was 771, who received $279,083 in wages, which were 91.1 and 81.1 per cent, respectively, of the total num- ber of emplo3'ees and total wages. There were on an average 38.5 wage-earners to a mine. Of the states, the statistics of which are shown in detail, New York had 21.1 per cent of the wage-earners, and they re- ceived 30 per cent of the wages paid. North Caro- lina had 8 per cent, and they received 7.7 per cent of the wages. Of the 771 wage-earners, onlj' 9S, or Vl.l per cent, worked below gr-ound, the remaining 673, or 87.3 jier cent, being enjphjycd above ground. >Some of these, however, were employed in cleaning and preparing the talc and soapstone for market, while all the under- ground wage-earners were directly emploj'cd in min- ing the talc. Besides tlie number of wage-earners mentioned above, tli<'re were 9 foremen included among the salaried employees, who worked below ground. Of the 771 wage-eai'iiei's, 411, oi- 53.3 per cent, are classitied as "'miners or quaiTymen and stonecutters;" of these 73, or 17.7 per cent, were employed in New York; 57, or 13.9 per cent, in North Carolina; and 281, or 68.4 per cent, in "all other states." In New York, 69 miners were emiolo3'ed underground and only 4 were reported as working above ground. In North Carolina, 8 miners were report(Kl as working underground, and in "all other states" only 3 were so reported. The daily rat(>s of ])ay of the wage-earners, as given in Table 5, varied from 5(> cents to $3.49 per day. Nearly one-half of the total lumiber of all classes of wage-earners, or 46. S per cent, received from %\ to $1.24 per day; 13i!, or 17.1 per cent, were paid from $1.25 to §1.49 per day. The highest rate of pay was received by those classitied as "all other wage-earners," 16 of whom were paid fi-om $3.25 to $3.49 per day, these being emploj-ed in the mamifacture of the more intricate articles made from soapstone. Of the 411 miners or quarrymen, 249, or 60.6 per cent, received only from $1 to $l.i4 per daj', this being due largely to the fact that mtist of these workmen were employed in the southern mines, where the rate of wages was nuich lower than it was for the same class of labor cith(>r in the North or East. The average luunber of wage-earners employed dur- ing each month is also shown in Table 5. The liusiest months for the industrj' were August, when an average of 826 eniploj-ees were at work, and September, when the average reached 841. The month with the smallest average was November, with 705. In New York the greatest average number employed was 168, that num- ber working in January and December. In North Carolina the greatest average was 85, employed in July, xVugust. and Septen:ber. Sv,pplle><., ii>at per ton has rtmi^ed from $9.13 in 1898 to $lti.o7 in 1883. In 1903 the prices re- ported as I'eceived for the talc and soapstone products varied from $3.35 for material sold in the rough as cpiarried, to $31,035 received for manufactured articles. This'wide variation in price is readily explained ^3y the various uses to which talc and soapstone are put, and to the amount of work that is required in preparing the manufactured articles for market. The imports of talc, 1880 to 1903, inclusive, princi- pally from France and Italy, as published by the United States Geological Survey, are shown in the following table: T.\BLE 4:.— Talr Imported intii the United States: ISSO to 190J.

DESCRIPTIVE. 'i'lic name laic lias been used \ery coimnonl\', and yet eri-oneously, for ii number of minerals which are simi- lar to it in physicid proyjerties, but distinct nn'nei'tilogic- ally. Coimnereially, the. name talc is usually applied to the hbrons tind I'oliated \arieties, which arc the purer foi'iiis, and the ntime soapston(^ confined to the massive \'arieties. MinertUogically, the name talc re- fers not only to the foliated and fibrous varieties, but also to those which are compact, and soapstone oi- stea- tite is simply a variety of this miiiei-al. Talc may be considered as occurring in tlie \arieties, foliated and massive, with a third division known as fibrous talc, which is usually called pseudoniorphous, as it has gen- er.dly resulted from the alteration of the mineral ensta- tite. The foliated talc is the most valuable, being pure and very free from grit, so that it is suitable for use in the mtuuifacture of ttilcum powders, etc. Occasionallv this variety is so compact that it can lie used in the manufacture of tailors' pencils, when it commands the highest price paid for anj' talc. Certain varieties of the massive talc are also pure enough to be ground into a flour talc, 1)ut the greater portion is used in the man- ufacture of soapstone articles. The propeifies of talc (exclusive of soapstone) that make it suitable for the purposes for which it is used are its extreme softness, its purity or freedom from grit, its stability, and its smooth, slipperv surface. Since the minerals serpentine and pyroiDhyllite closely approximate manv of these properties, they are used to some extent for the same purposes. This is true especiiilly of the latter, which can lie used for many of the purposes for wdiich flour talc is employed. y quar- rying. Practicidly all of the Pennsyhania and New Jersey talc oi- soa])stone is ])ut on the market in the form of a ground product, most of which is used in the manufacture of paper. St. Lawrence c(uuity, N. Y., is the scene of the largest talc industries in this country. The talc is of the hbrous variety, and is used almost entirel}^ in the manufacture of pa])er. There are about twelve mines in this talc region, and they are located near Talcville, St. Lawrence county, and Littleyork, Cortland county. Since the consolidation of a number of the smaller properties the mining and manufacture of ground talc has been carried on moi'e systematically and on a larger scale, thus increasing the production of talc in this state and decreasing the cost. About 3 miles southeast of the \'illage of Kochester, Vt. , are old talc mines which were worked rather ex- tensively during LS65-(J(3. These are now l>eing re- opened and tleveloped, and the material will be put on the market as ground talc. There were no new deposits that produced talc during l'.t()2, although some work was done in investigating dejoosits. most of the deposits imestigated. however, proved to be of little or no eonunercial value, being for the most part of the steatite variety. J/ithoiIs iif III I II ing . iiii'ui i{f(ictii I'l IK/, and ilt'iiii ini'i. — The mining of talc is either (1) l)y means of open cuts and pits, (2) by a system of shafts or tunnels and drifts, or (3) occasionally by a comliination of lioth cuts and shafts. The mining of the soapstone (steatite) is largely liy the first method. Mining l)y shafts, tunnels, and drifts is confined to the foliated and fibrous \'arie- ties of talc. In N(>w York the method of mining is practically the same at all of the mines. Inclined shafts arc sunk, following the dip of the country rock, which is first gneiss, and then massive white dolomite, as the beds of talc are approached. These rocks stand very well, so that tindiering is required only occasionally. When the shafts reach the beds of talc, drifts are run along the strike of the deposit. On account of the com- pactness of this talc, blasting is usually necessarv in re- moving it. .Vs the talc comes from the mine it varies in si/e from particles no larger than dust to masses two feet (ir more in length, and it is conveyed in hand cars to the mills, where it is puherized. The larger masses ai-e broken with sledges and then passed through Blake crushers and conveyed by a Ixdt to a pair of slightly corrugated steel rolls, which reduce the talc to small pieces, one-foui'th inch oi' l(>ss in length. From the rolls the crushed talc is carried by an endless belt conveyor to bins on the top floors of the mills, ar, '. tlien it is con- veyed automatically into Griffin mills on the floor below. A draft of air is forced through the mill, and as tlie talc becomes fairly fine it is l:)lown through an opening and falls to th(> flooi- lielow. It is returned to the second floor and coin'cyed into large hopper shaped bin cars, From which it is (Iroi)ped into Alsing c\-|inders, in which is a ([uantity of watei'worn ([uart/ pebbles, 2.2 inches or less in diameter. As the cxdinder revolves TALC AND SOAPSTONE. 1065 the constant pounding and rubbing of tliesc quartz peb- bles on the talc completely pulverize it. Fi-oni this cylinder the talc passes through a grating, thus Ijecom- ing separated from the (juartz pebbles, and is conveyed automaticall}^ into a bag hlling machine, M'here it is bagged and weighed, read}' for shipment. Talc mining in North Carolina does not present any serious difficulties, as the deposits do not iwtend to any great depth. The presence of water in the mines in the lowlands occasionally causes considerable expense and loss of time. Most of the mines thus located have been worked by means of open pits, which during a period of lieavy rain have to be aljandoned on account of being flooded. Although some of the deposits, especially those on the hillsides, can be worked advan- tageously by means of open pits, the majority of them arc worked to the best advantage when shafts or tun- nels and drifts are used. Little lilasting is necessary at any of the mines, as the talc can usually be removed readily by pick and gad. As the rough blocks of talc are taken from the mine the\' are hand cobbed if necessary and sorted into three grades. The larger pieces are cleaned by rubbing them with steel l)rushes, and the smaller ones by a founder's scouring machine. They are then dried by being spread over a floor of steam pipes, which are kept at a temperature of •21'2''' F. When these jjieces are drv thej' are crushed and ground by means of crushers, rolls, and pulverizers, and the foreign material removed l)y screening. It is then further ground in buhrstone mills, similar to those used in grinding wheat, and passed through bolting cloth, which makes the flnal product nearly uniform in grain. This ground product is handled very nmcb like flour, and in iilling the liags with the flour talc, an ordinary flour packer is often used. In Maryland, New Jersey, Tennsylvania, and Vir- ginia, whore it is principally the steatite variet}' of talc that is produced, the mining operations are carried on almost entirely in ver^^ large (jpen cuts and pits. The preparation of the ground talc from the New Jersey and Pennsylvania mines or (juarries is a process similar to that described abo\'e. In Virginia, where the soapstone is used almost exclusively for maimfac- tured articles, the tonnage mined is of course very miU'h larger than the weight of the articles manufac- tured and put on the market. f'titv. — Talc is employed in the arts in two distinct foi'ms, as powder, or flour talc, and as pieces sawed into various sizes and shapes. The flour talc is now used as a base for fireproof paints, lubricants, and many of the cheaper soaps, for electric insulators, for Ijoiler and steam pipe coverings, for foundry facings, for the dressing of skins and in the manufacture of dynamite, of the various toilet powders and of paper. Formerly certain varieties of clay were used as a filling in the manufacture of paper, but with the discovery of large deposits of talc, especially of the fibrou.s variety, in New York, talc has largely replaced them, its fibrous and pliable character giving additional strength as well as weight. The introduction of talc in the manufac- ture of toilet powders put on the market under the name of talcum powders gave a new use for the more valuable talc. The soapstone, or steatite varieties of talc, are used for the most part in the manufacture of hearthstones, linings of furnaces, for cupola and converter linings in many steel works, for laboratory tables and ovens, for laundry tubs and slate pencils, and, to a limited extent, in Ijuilding. It is also used quite extensively in the manufacture of soapstone griddles, foot warmers, boot driers, and for man_v other articles of evervdav use. lOfin minp:8 and quarries.

MAGNESITE (1067) MAGNESITE. By JosEi'ii Stkuthees, Ph. D. The output of mag-nesite in the United States is ob- tained solel}' from California. The mineral occurs in other states, but the deposits are not of sufficient extent or purity to render their exploitation a connnercial pos- sibility. The deposits of this mineral occur in several localities in California, but a mine located in Tulare county was the only one in active operation during 1902. It is impossible, therefore, without disclosing individual operations, to publish the complete statistics for this branch of the mining- industry, and they are included in the group of ''all other minerals" in the general tables. Of the magnesite mines which were idle during 1903, 2 are located in Alameda county, 2 in Napa county, and 1 each in Santa (^lara, Sonoma, and Stanislaus counties, a total of 7. The mineral has also been found in San Bernardino county. Production. — During 1902 the production of magne- site in California amounted to 3,086 short tons of crude ore. Of this product 2,236 short tons were calcined, the result being 1,050 short tons of the calcined product, valued at $15,780. The remaining 850 short tons of crude ore were valued at $3,859. The value of the entire product was therefore $19,639. The quantity and value of crude magnesite marketed in the United States during the years 1891 to 1902, in- clusive, including the value of the calcined product, is given in the following table from the reixn-t of the United vStates Geological Survey: Table 1. — Frodvctioii of magnesite: 1S91 to 190-1.

IS, 4.S0 19, 333 43, (B7 21,362 The census figures for 1902, as given in the text, are for the quantity mined that j'ear, while those of the Survey include 38<» tons, valued at $1,723, mined previouslv but sold in 1902. The production of crude magnesite is practically under the control of one tirm in California, which ships much of the output to two manufacturers of carbon dioxide gas for use in the production of the gas bj' cal- cination. The calcined product, essentially magnesium oxide, or magnesia, is returned to the shipper and is subsequently utilized by paper mills in California and Oregon. The demand for calcined magnesite for this purpose in the West is limited, and only a small por- tion of the available supply is utilized — a trade condi- tion which is reflected by the difl'erent unit value of the cidcined product from j-ear to j-ear when considered in connection with the quantities produced. Thus in 19()0 the supply of calcined magnesite amounted to 1,013 short tons, and the average value per ton was $15.70; in 1901 the output, 1,726 short tons, far exceeded the demand, and the average value decreased to $5.57 per ton; in 1902 the quantity produced, 1,050 short tons, was again just sufficient to satisf j' the normal consump- tion, and the average value per ton rose to $15.03. Consinnjjtion. — It is impracticable to furnish accurate statistics of the consumption of magnesite and of magne- site products in the United States, owing to the fact that ill the official reports no distinction is made between the imports of crude and of calcined magnesite : furthermore, the statistics of the quantity and value of imported mag- nesite bricks are not separately reported. During 1902 the imports of crude and calcined magnesite (which were chiefly from Greece and Austria) amounted to -±9,786 short tons, valued at $373,928, as compared with 33,461 short tons in I'.tOl. There was also a very large impor- tation of magnesite bricks, ))ut no statistics of their quantity or value are available. By adding the figures for imports to the figures for the marketed production, as given bj- the Geological Survey, an estimate may, however, be made of the consumption exclusive of the quantity contained in brick form; on this basis the (1069) 1070 MINES AND QUARRIES. quantity of crude and calcined nuignesite consumed in the United States during V,H)'2 was 53,252 short tons, as compared with -if^tiSS short tons in 1901 and 31,070 short tons in 1900. These statistics show the increas- ing importance of magnesite in the industrial arts in the United States; they also show that only a very small fraction of the supply is of domestic origin. The industry intJie United States. — Magnesite is found in many localities in the United States — in California and in Massachusetts; at Bare Hill, near Baltimore, Md. ; near Rj-e and at Stonypoint, N. Y. ; near Hoboken, N. J. ; in Yancey and Cabarrus counties, N. C. ; in Ches- ter and Lancaster counties, Pa.; in Arizona and in Texas. But the deposits have been worked with com- mercial success only in the first-named state. The deposits in California are quite widespread, occurring in the following counties: Alametla, Colusa, Fresno, Kern, Mariposa, Monterey, Napa, Placer, San Luis Obispo, Santa Clara, Stanislaus, Tulare, and Tuolunuie. The only producing property during the year Mas in Tulare county, near Portersville, where the mineral occurs in a series of vertical and flat veins, in some cases 10 feet in width, and has wall rocks of serpentine and granite. Some of these veins outcrop boldly, and a few of them have been traced on the surface for sev- eral thousand feet. A large (juantity of mineral has been disclosed l)y open cuts and a tunnel. A lo-ton kiln, using crude petroleum as fu(d, serves to calcine the product, which is then shipped to paper mills, and a second kiln will be erected as soon as the demand warrants it. The calcining treatment, Avhich is carried on at a temperature of 2,50(1''' F. , occupies from three to three and one-half hours; the carbon dioxide gas expelled is allowed to escajjo into the air. Li the calcination of magnesite, 4s to l<-2 [ler cent of its weight is lost by the expulsion of the carbon dioxide. The cost of the cah'incd product at the kiln is from $12 to §14 per ton. Tlic deinaiul for magnesite has increased rapidly east of the Kock\- mountains, Ijut owing to the high cost of transporta- tion from the Pacific coast, most of the mineral used is imported, mainly from (rreece. An important i)rol)- lem of the industry in California is t(j reduce the cost of calcination to a point which will admit of the ship- ment of the calcined pi-oduct to Pittsburg, ^\■here it might be used for the manufacture of magnesite brick and other refractory products, an industry in which at present magnesite imported from the,' island of Euboca, in Greece, and from Styria, in Austria, is used. An- other important feature is the development of tlie iron and steel industiy on the Pacific coast, which will give a strong impetus to the mining of magnesite and its manufacture into bricks and concrete for use as a basic lining of furnaces oi- convcrtei-s, for treating phos- phoric pig iron to make basic open-hearth or basic Bessemer steel. The industry in foreign crjuntries. — The greater por- tion of the world's production of magnesite at the present time comes from the deposits in Austria and Greece. During 1901 the exports of calcined magne- site from Austria amounted to 40,236 metric tons, valued at $321,800. The deposits in Austria have attained their greatest development near Vietsch. The formation is of the Silurian age and consists of argillaceous shales, quartzite, dolomite, and gneiss. The magnesite occurs in beds conformable with the strata and is usually seamed with calcite, dolomite, and quartz, with occasionalh' segregations of dolo- mite crystals; it is necessary, therefore, to cob and pick tlie mineral. The sorted ore, which usually contains from 90 to 9G per cent of magnesium car- bonate, is calcined at a wdiite heat in kilns lined with magnesite bricks at those sections where the temperature is the highest, in order to prevent the introduction of impurities into the material. The small amounts of silica and ferric oxide contained in the ore are sufticient only to sinter it. The kilns are continuous in action and yield SO tons of calcined ore daih^ This product is sorted mechanically for the removal of the fine dust, as well as quartz and other impurities, that may not have been separated in the preliminary cobl)ing process. The sorted calcined material is then crushed, formed into bricks in steel molds ])y hydraulic pressure of about4,50o pounds per square inch, and finally burned in kilns at a high tem- perature, thus producing the solid and compact magne- site ))rick as it appears in the trade. Li Greece the magnesite mines are near Mantudi and Limni in the northern part of the island of Euboea. The mineral is in cryjjto-c'ry stall ine form and occurs in large \-eins m serpentine; picked samples contain as high as KS per cent of magnesium carbonate, but tiie a\'erage composition appro.ximates 1>5 per cent Foi'inerly the sorted ore was calcined in kilns fired by wood, but this process has been cheapened by j the introduction of modern shaft calciners using a local lignite fVir fmd. Ordinarily the completely cal- 1 cined t)re falls to powder when moved and causes the i lower ami cooler portion of the ordinary kiln to become dioked with finc^ material, thereby preventing the access of air which is necessary for the combustion of the fuel. The modern furnace is constructed espe- cially to overcome this defect. The magnesite from Euboea is exceptionally pure and on account of the absence of impurities, it sinters only at a verv high temperature. As this magnesite is so highly refrac- tory, it is nt'cessary in the manufacture of bricks to add a suitable l)inding material. At the brickworks at Mantudi, a small proportion of serpentine is added to the mixture which is molded and burned at a tem- ]>erature of 1,400'^ C. in a. i'egenerati\'e furnace of the Siemens type, yielding a very hard and dense brick. MAGNESITE. 1071 Deposits of magnesito have been found at Sutton and Bolton, Ontario, Canada; near Frankenstein, (Terniany; in tlie Department of Ufa, southein Urals, Russia; in India; and at several localities in Hungary. A few of these deposits have been worked, but the output fi-oni them at the present time is very small, when coini)ared with the total production of the w.orld. Oceiirre)>ei_' and vharacterivficv. — Maynesi te. magne- sium t'arl)onate (MgCO.,), corresponds chemically to calcite, calcium carbonate (CaCOj). In the pure state, it contains 47. (> per cent of magnesium oxide, and 52.4 per cent of carbon dioxide. When impure, mag- nesium silicate is present and at times iron oxide. Pure magnesite occurs in transparent, rhomboliedral crystals; in the massive form it is compact and granu- lar, resembling unglazed porcelain in appearance. In color it is generally white, but often of a yellowish, grayish, or even brt)wnish tinge. The brownish color is imparted to the mineral by the impurity, iron oxide, which if present to the extent of several jjer cent forms the variety "lireunnerite," or "brown spar," as it is sometimes called. In hardness magnesite varies from 3.5 to 4.5, and though brittle, it is exceedingly difficult to drill. Its specific gravity varies from ?> to 3.12. The formation of magnesite, which is usually asso- ciated with serpentine, is attributed to the action of carbonated waters uj^on eruptive magnesium rocks, such as olivine (chrysolite); when this action has been carried nearer to completion, the serpentine also is decomposed, yielding as final products magnesite and quartz. While magnesite generally occurs associated with serpentine, it is found also with other niagnesian minerals, as talc, brucite, dolomite, etc. It is some- times found in gypsum, and when the veins are irreg- ularly mixed witli the gypsum the mass forms the variety of marlile known as "verd anticpie."" Usefi. — In the crude condition magnesite is used largely for making carbon dioxide gas, either by the ai)plication of heat alone or b}' treatment with sul- phuric acid. The carbon dioxide so produced is util- ized largely either in the gaseous or licjfuefied state to "charge" or carbonate mineral waters and other be\'- ei'ages, and its use in mechanical refrigei'ation in warm countries and on shipboard is inci'easing. When crude magnesite is dccomi)osed by sulphuric acid, magnesium sulphate is obtained as a by-product, whidi, being dissolved in water, filtered, and crystallized, yields Epsom salts (MgSO,,, 7II,,0). During 1H02 it is esti- mated that at least 17,5(H),()(MJ j^ounds of this salt were produced in the United States. At least 90 per cent of the domestic output of Epsom salts produced during l'.H)2 was consumed in the manufacture of dyes, laun- dry soaps, and paints, and in tanning leather; the remaining 10 per cent was used in the preparation of medicinal salts. Early in 190,3 a covjibination was efi'ected of the various concerns engaged in making Epsom salts in the United States. Crude magnesite is used to a minor extent in the manufacture of the mag- nesia alba of pharmac}". This preparation is a mixture of magnesium carbonate and hydrate. The consumption of magnesite in its calcined state (which corresponds to magnesia, MgO) has increased very largely since l.s99, owing to its uses in the form of bridvs or concrete as a refractory lining for o^DCn- hearth furnaces and Bessemer converters in the steel industry, and for special parts of furnaces used in the smelting of copper and lead ores; as a lining for rotary kilns used in the manufacture of Portland cement; as a nonconducting covering for boilers, steam pipes, etc., to prevent loss of heat: and more recentlj' in electric furnace construction as a refractory material. It is used also in the manufacture of paper stock by the sul- phite process, the wood pulp being digested luider pressure in calcium-magnesium acid sulphite, whereby the lignin which forms the coloring matter of the wood, as well as other incrusting material of the fiber, is con- verted into solul)le products, which are subsequently removed by washing. The general adoption of the basic process of making steel has also largely increased the use of magnesite for furnace linings, especially in the form of bricks. MINERAL INDUSTRIES OF PORTO RICO (1073) 30223—04 68 o Ok O o H o H Hi o Pi -a ^ Q fi J Q O 03 M MINERAL INDUSTRIES OF PORTO RICO. By William F. Willoughbt. The investigation of the mineral industries of Porto Rico for the year ending December 31, 1902, report of which is given in the pages that follow, representing, as it did, the first attempt to present a comprehensive exliibit of the character and importance of the mineral resources of the island and of their exploitation, had to contend with the difficulties usually attendant upon initial statistical or census work in any field. These difficulties consisted not so much in securing data con- cerning mineral deposits and tlieir wortcing, after their existence was known, as in securing information con- cerning such existence and worlving itself. In the present case this difficulty was especially acute oAving to the lack of official data and the fact that in no case were mining operations being conducted as a regular industrial enterprise. Such work as was done during the year was almost wholly of a prospecting and experi- mental character. Even brickmaking and stone quar- r3'ing were carried on in an intermittent manner, bricks being made as demand arose for them and quar- ries being worked here and there by contractors in need of material for roadmaking. In view of these conditions it was deemed that the most important work that could be done by the investi- gation would consist of presenting (1) such historical data as could be obtained regarding the search for, and discovery of, minerals in the past, and efi'orts that had been made for their utilization; (2) a statement of the laws in force regarding the location and exploitation of mining claims; (3) a list of all mineral deposits of which information could be secured by making the most thor- ough investigation possible; and (-i) an account, with such statistical data as could be obtained, of work actu- ally done during the year in the utilization or manipu- lation of such mineral resources. In these efforts it is believed that, thanks to the co- operation of the different insular and local officials, a" large measure of success has been attained. The thoroughness of the canvass may be seen from the fol- lowing statement of the means employed in securing information. In addition to the personal researches of the author and his assistants, information was sought and secured from each of the sixty collectors and deputy collectors of taxes attached to the Treasury Department of the island, whose duties are such as to make them personally acquainted with eveiy important taxpa3'er or industrial enterprise in their respective districts, from the twenty-odd internal revenue agents whose duties take them to every part of the island, no matter how difficult of access, and finally from all the contractors and superintendents engaged in the con- struction or maintenance of the highwa3^s. The com- missioner of the district of Porto Rico and the chief of the Bureau of Mines under his jurisdiction likewise rendered everv possible assistance in the wav of fur- nishing data taken from official records and in directing all of their emplo_yees to furnish any information in their power. Mining, as generally understood in the United States, has not up to the present time been a stable industry in Porto Rico. Certain minerals were known to exist by Ponce de Leon and his followers in the early part of the sixteenth century, but no svstematic or scientific methods were then, or have been since, employed in their extraction. The absence of any relics pertaining to the period antedating the discoverj- of the island \)y the Spaniards would tend to show that metals were not used in the manufacture of warlike implements or domestic utensils, neither has there been unearthed any metal adornments, such as anklets, arm rings, or similar decorations with which primitive tribes conversant with the use of metals were wont to adorn their women folk. The complete absence also of shafts, tunnels, and other evidences of ore mining, such as are being constantly uncovered in other Spanish- American countries, would further tend to confirm the opinion that neither the Borinquenos nor their Spanish conquerors practiced mining except in a desultorj' manner, and the lack of historical mention of such industry likewise strengthens this belief. Fray Ifiigo Abad, in his " Ilistorj^ of Porto Rico" (1788), makes reference to early remittances of gold to the Spanish peninsula, but all the gold extracted was undoubtedljf olttained from river washings bj' en- forced native labor.

Otficial or other reliable data relative to the geolog- ical formation of the island is also practically nonexist- ent. Some attempt to compile a report on the subject was made by Angel Vasconi, a Spanish engineer, and the result of his labors was laid befor(^ the directors of the Exposition of Mineralogy held at Madrid in 1883. The monograph comprising the report is not extant in Porto Rico, but a portion of the rough draft was found among the archives of the insular Bureau of Mines by its present chief and was large h' drawn upon liy the Governor of Porto Rico in his second annual report to the President of the United States. The information therein contained is considered worthy of reproduction as presenting in succinct and precise form what little is known of the mineral bearing formations which go to make up the soil and subsoil of this new possession of the United States. [Extract from the second annual report of the Governor of Porto Rico to the President of the United States.] Gold placers were worked for some years by the Spaniards in the first century of the conquest, and, according to official statistics, 2,700 pounds of gold were sent to Spain from the year 1509 to the year 1536. It is believed that that figure only represents the part belonging to the Crown of Spain— that is to say, the fifth of the total production during that period of time. The Sierra de Luquillo, the more abrupt and the highest of all the mountains in Porto Rico, belongs to the main <'ordillera, or chain, which cuts tlie island from east to west, with a prolongation to tlie Windward Islands, by the east, and to the little island of Desecheo, situated opposite to Mayaguez and Aiiasco, by the west. That mountain, or sierra, is in the northeastern part of the island, and owing to its situation and the elevation of its hills — the highest being El Yunque, 1,200 meters [3,937 feet] above sea level — is the first vessels can distinguish in coming to Porto Rico. From VA Yunque and the hills named Cuchilla Firme, Meseta, PefiaParada, and others, various rivers flow in which gold has lieen found. The Mameyes, one of the richer in gold, has as tributaries the rivulets known as Filipina, Cajones, Guaraguao, La Mina, La Maquina, Tabonuco, and Anon. In this last named, the Anon, soirie thirty- eight years ago, a riili concern did some work in the washing of sands or auriferous alluvia, obtaining from one to two pounds of fine gold per day. The rocks more abundantly found in the watershed of Mameyes River are eurite and porphyry, crossed with veins of quartz and iron pyrites. The alluvial lands occupy a good exten- sion of the middle and lower pjarts of these watersheds, and are composed of clay, sand, and bowlders, forming deposits of analo- gous nature. Their depth is variable. In the valley of the Anon there are .some cuts, from si.x to eight meters (20 to 2() feet) deep, made in such alluvial deposits with the view of exploiting the auriferous strata. It is known that the watershed of the rivers Corozal, Negros, Congos, Cibuco, Mavilla, and Manati c(jntaiii auriferous sands. The idea which occurs to one examining the vicinity of t'orozal is that that valley was enqitied, through a process of erosion, by the diluvial waters, which produced in the calcareous soil cuts more than 130 meters [427 feet] deep, through which ran a stream. It is believed that the waters of that stream deposited the (luaternary alluvia. The calcareous soil, said to be of thi' Tertiary formation, occupies the right shore of the river and exlends itself bv the north toward the sea. On the left sl](jrc, and in the lied of the river, the limestone has disappeareil, giving place to potent strata of sandstone, on \vhich the auriferous (|uaternary alluvia lay. The alluvial deposits are more potent the lower they are, and golil is found very near the surface in the higher and hilly iiarts, while, on the contrary, in the great .deposits of the lower parts of the valley the auriferous strata are covered by sterile masses. Xear the source of the Congos River, in the bed of it, and 25 centi- meters (9.8 inches) deep, some jjieces of quartz have been found containing from 8 to 10 grams [123 to 154 grains] of pure gold. In the jurisdiction of Corozal some washing machinery was estab- lished, and the result was from $2.17 to $4.30 for each ton of sand. There are also, according to otficial information, some gold placers in Mayaguez, San German, Y'auco, and Coamb. The gold is found in grains or nuggets of $2 or $3 value, and, rarely, nuggets of even higher value. In the Fajardo River a piece was found which weighed 4 ounces, and in the Congos another piece of 1 pound was also found; but the biggest jiiece of pure native gold was discovered in the lands belonging to .Mr. Bou, in tlic jurisdic- tion of Corozal. That piece was sold to Mr. Bou by the finder for $200 in monev and some other valuable things. In the bed of the Filipina rivulet there were obtained from 60 kilograms [132 pounds] of sand six -tenths of a gram [9 grains] of pure gold, which makes 10 grams [154 grains] for 1 ton of sand. The enterprises mentioned were abandoned, and the only work on the mines was done bv the "lavadores," washmen. They use an instrument called "gaveta," made of wood, shaped like a ]ilate, of 40 centi- meters [16 inches] in diameter and 12 centimeters [5 inches] deep. In the watersheds of Mameyes River and in all the rivers crossing the jurisdiction of Corozal numbers ..f peasants can be seen engaged in the wcjrk of washing auriferous sand, from which they obtain gold in amount sufficient to pay for their support. Since the American occupation, work on the mines has had renewed life, and the number of applications for mining conces- sions filed in the Bureau of Agriculture and Mines has increased. LTp to .July concessions have been granted for 107 hectares (264 acres) of land. The minerals of copper obtained are: Ferriferous motley copper, native copper, green and blue carbonates, yellow copper sulphide, often accompanied with iron pyrites and iron oxides. Spanish explorers of the island paid little or no attention to copper. It is general!}' found along the main chain of mountains dividing the island from east to west, from the neighboring island of Vieques, and then following through Rio Blanco, Gurabo, Corozal, Ciales, Jayuya, Maricao, and some other jilaces which belong to the south- ern chain of mountains, such as Las Piedras, Ilumacao, Ponce, Piilalejo, and also in the vicinity of the road from Caguas to San Juan, the richest place being the tiarrio of Rio Blanco, in the municipality of Naguabo. The first works for the exiiloitation of cojiper began in 1869. In the mine named "La Aliundancia" some small excavations were made, and the superficial carbonate was gathered, and many tons of rich mineral were thus obtained. Like results were reached in the mines named Santa AmaMa, La Cas- tellana, and Santa Tere-sa, all located in the barrio of Rio Blanco. In the last-named mine copimr indications were noted from the surface to a depth of 25 meters [82 feet], first as green carbonate \\;ith 23 per cent of copper, then as ferriferous motley coppei', and, in some parts, yellow sulphide, very pure. In 1879, 10 tons of copjier sulphide were obtained from the mine Santa Teresa, and 60 tons of carbonate of copper from the Santa Amalia. Owing to the difficulties and high prices of transportation, work ceased. The existence of silver in the island has been oflScially recog- nized. OnJuly 19, 1.538, the "oficiales reales" wrote to the King of Spain that " veins of lead containing some silver have been found," and on March 29 of the following year they wrote, 'M\'ith respect to the silver mines here discovered we arranged that that mineral be fused here, but there is no person v ho knows how to do it. In some jilaces veins of that metal have been found, but nothing has Ijcen done, waiting the arrival of some one who knows how to fuse PORTO RICO. 1077 and work it." In the History of Porto Rico, by Fray Ijligo A))ad, witli notes by Don Jos6 Julian Acosta, tlio .statement is made that in the Serrania de Anasco tliere was a mine containing silvei-; and, in a report prepared in 1879 by the chief engineer of tlie buieau of mines, reference is made to certain samples of silver found in the barrio Llamos, of the municipality of Isabela. In other olhcial documents the existence of silver iu the northwestern part of the island is athrmed. Concessions have been made of silver mines in Naguabo, Corozal, Rio Grande, Fajardo, Lajas, and Las Piedras. In the subsoil of the eastern part of the island there is felds]>athic rock. Tliis section is confined on tlie north by the Sierra de Luquillo, and < )n the south by the Pandura, parallel ranges of hills, and distant one from the other from 25 to 30 kilometers (16 to 1(1 miles). It is stated that the surface lodes occupy a large area, tlie depth not having been determined as yet. Iron is found, accord- ing to tests made, at the rate of 61 per cent of the nnneral. Iron of excellent quality has been found in the barrios Mameyes and Jayuya, municipality of Utuado, and in Luquillo, Piedras, Naguabo, Humacao, Gurabo, Patillas, San Lorenzo, and Arroyo. The con- cessions of iron mines are numerous. Some efforts are being made now with the view of organizing enterprises for the exploitation of iron in the eastern part of the island. There are in the island, according to official information, some deposits of lead minerals. Good samples of galena have been found in Arroyo, Mayaguez, and Naranjito. There are two concessions granteil in the municipality of Guayama, one being for the exjiloita- tion of lead and the other for argentiferous galena. Minerals con- taining some amount of peroxide of manganese have been gathered in the vicinity of Corozal. Native bismuth has been discovered in Ponce. Samples of platinum, tin, and mercury have been obtained in the jurisdiction of Corozal. All other official reports touch but lig'htlj' on the mineral resources of the island and do not convey any information not embodied in the foreo-oing- extract. Mr. Robert T. Hill, of the United States Geological Survey, in his accurate and interesting work entitled "Cuba and Porto Rico," devotes but ten lines to the subject, saying: A little placer gold is found in the rivers of the Sierra Luijuillo and Corozal, and mercury in the Rio Grande. Gold was formerly mined by the early Spanish settlers and is still taken out in small quantities by the natives. Molybdena, magnetic pyrite, man- ganite, limonite, chrysocolla, epidote, and garnet are the minor minerals found. Specular iron is reported in several places, notably in the river Cuyul. Magnetic iron is also reported from Gurabo and Ciales. Crystals of (juartz are found in the Rio Prieto, agate of good quality at Caja de iluertos, and malachite at Rio Blanco. MINING LAWS. Notwithstanding the absence of anything approaching an organized mining industiy in Porto Rico there is, nevertheless, a complete system of lav/s and regulations governing the right to exploit both precious and base metals in the island. This is substantially contained in the law of July 6, 1S.5!), and the ministerial order of December ii9, IStlS, enacted originally for application in the Spanisli pen- insula only, but subsequently extended to Porto Rico by the law of May 3, 1895. j^Iany of the provisions of these statutes have by reason of the ch.mge of sover- eignty become inapplicable, and it is understood that a new mining law is being drafted and will ))c presented at the next session of the insular legislature. In so far as possible, however, the principles and procedure of the existing laws are being observed, and deficiencies arising from changed political conditions treated by analogy. Minerals subject to mining claims are divided by the law into three classes, as follows: Class I: Minerals of an earth}^ nature, minerals of a siliceous natuix', slates, minerals of a sandj^ nature, granites, basalts, limestones, gypsums, sands, marls, clayey earths, construction materials in quarry forma- tion. Class II: Placers, metallic sands or alluvia, bogs, emery, ochers and almagras, scoria and mineral tailings, peats, pyritic earths, aluminous earths, magnesium earths, salt deposits, lime phosphates, barytes, fluor- spars, steatites, ravolins, clays. Class HI: Metallic veins, anthracites, pit coals, lig- nites, asphalts, bitumens, petroleum and mineral oils, graphites, saline substances, including alkaline and ter- raceous salts, either solid or in solution, copperas, sul- phur, precious stones, iron ores. In order to obtain legal title to a mining claim the claimant must submit a petition to the C'ommissioner of the Interior of Porto Rico setting forth the area of the desired claim, the class of mineral to be worked, and the name of the owner of the pi'operty wherein the claim is situated. He must also furnish a survej' of the claim and, within ten daj's from date of tiling his petition, must deposit the sum of $36 if the claim does not exceed in area V2 pcrtenencias (30 acres), and $1.20 for each additional pertenencia. No claim can be tiled for less than -1 pcrtenencias, but there is no limit to the number of pertenencias that may be included in one claim. Each pertenencia nmst, however, be con- tiguous along the whole of one of its sides to some other pertenencia of the same claim, and must consist of a regular square, each side measuring 100 meters (328 feet). The aforesaid dejJosit is to cover the ex- pense of an ofiicial survey made later by the Govern- ment. The first conditions being complied with, the petition is advertised for sixty days to enable protests to be tiled, which protests are submitted to the claimant for reply within twent_y days. The complete brief is then passed upon bj^ the Commissioner of the Interior of Porto Rico, and his decision, if favorable to the claimant, is followed by the appointment of a surveyor to lay out the claim and the payment of a further fee by the claimant, amounting to tio cents per pertenencia (2^ acres), to cover expeusi>s of title. A title signed liy the Governor is then issued, and is valid forever, subject to an annual rental (canon de miuas) of $'2A0 per pertenen- cia for precious metals, or 96 cents per pertenencia for base metals. This title does not carry any obligation to work the mine, and lapses only on failure to pay the annual rental. Pending legislation relative to the disposition of pub- lic lands (terrenos baldios), no mining claims are being- allowed on public property. 1078 MINES AND QUARRIES. PRECIOUS METALft.

The owners of each of the above-enumerated claims have been interrogated by letter as to whether their respective claims were in oper- ation, but except from the owners of two of these claims (Augusta and La Palma) no response has been elicited. The owners of the other mines are not to be found at present in the island. It may, therefore, truthfully be said that ore mining of precious metals is entirely prospective and confined to the tiling and registration of the above-mentioned claims, none of which is being- exploited. PLACER GOLD MINING. Such gold mining as is actually engaged in at present in Porto Kico is entirely of the placer type, unimpor- tant in scope and confined to the Corozal district of the island. There are some twenty or more miners of the peon class engaged steadily in the work of extracting gold from the sands of the river by means of an oscil- lating movement of the hands applied to a wooden disk in which the sands are washed. From the best informa- tion obtainable, the value of the gold thus secur(xl daily will aggregate, approximately, $25. It is understood that Mr. Henry D. Sa^'re, who is the cdVju'KsvDinifr of eleven mining claims in the Corozal district, intends shortly to operate on an extensive scale, Mr. Sayre is an expe- rienced miner, who has invested a considerable sum of monej' in (exploration, surveys, and assays in Porto Rico, and is said to be very favorablv impressed with the mineral wealth of the Corozal district. He has recently applied to the executive council of Porto Rico for a franchise authorizing him to divert the waters of the Mabille rivrr from their natural course with a view- to obtaining the de2:)osits of gold in the river lied. Whether any attempt at ore mining will be made bj- Mr. Sayre is not at present known, but it is understood that he claims to have discovered the original veins from which the deposits in the river bed are derived. Al- though there is evidence of placer mining ha\'ing been practiced in other parts of the island as well as in the Corozal district, particularly in the vicinity of San German, no mining for gold is at present carried on outside of the Corozal region. This failure to operate elsewhere in the island is doubtless due to the belief that the gold dejjosits in other sections have become so nearly exhausted as to preclude their extraction in quantities prolitable even for the peon class. BASK MKTALS. The foregoing description of the situation relative to precious metals applies almost in its entirety to the baser metals. The following mining claims have been tiled and are registered in the office of the Com- missioner of the Interior of Porto Rico, l)ut no single one of the min(>s appearing in the list is actuallj' being operated.

It is understood that some of the iron ore deposits are of an exceptionality rich character, fully etiual in percentage of mineral to the famous Daiquiri mines near Santiago de Cuba. These deposits are situated inland some five or six miles from the eastern seacoast town of Naguabo, and can not be operated with profit until means of transportation is furnished to tidewater. SALT. The production of salt in Porto Rico is confined ex- clusively to the southern coast. The process of solar evaporation is the onlj- one employed, and that in its most primitive form. Tlie consumption of this article, estimated from the be.st data obtainable, is about 300,000 quintals (15,000 tons) per 3'ear. All salt required for home consumption, as well as a large amount in excess for export purposes, could readilj^ be produced in the island, but owing to insuflicient capital (as alleged by persons engaged in the industry), want of skill in oper- ating, or inclemencj' of the elements, and notwithstand- ing the fact that a protective duty of 13 cents per hundredweight has been imposed on foreign salt intro- duced into Porto Kico, thousands of tons of this com- modity are annually imported from Curasao. The Curafao salt meets with read}- sale here at prices rang- ing from 20 to .5i> cents per quintal, whereas it is claimed that witli proper management salt can be pro- 1080 MINES AND QUARRIES. duced in Porto Rico at a maximum cost of KJ cents per quintal.

In view of the abnormally small production of salt in Porto Rico in 1902, shown in the above statement, it is of interest to reproduce here the reasons advanced therefor h\ some of the operators: The reason of the production of the extremely small quantity of 650 bushels is the heavy rains which fell during the year 1902. In other years six, eight, or ten times the amount was produced. The insignificant duties paid by foreign salts give rise to the anomalous condition in Porto Bico of importations from Curac^ao and other places of a larger amount of salt than is manufactured in the islainl. During the year 1902 no gait was produced from the deposit (Fortuna), the hurricane of 1899 having completely destroyed its utility to its former owners, and the whole of said year (1902) being employed by its present lessees in getting it into shape again. Said deposits (Carmen and Monserrate) have in former years produced 2.5,000 to 30,000 quintals. The small production in 1902 was owing to the early rains along this coast. The salt industry of Porto Rico does not produce the fifth of what it should, owing to the lack of capital on the part of the operators. With an initial expenditure of $.5,000 the deposit I own should produce 100,000 quintals of salt. CLAY PRODUCTS. No attempt has heretofore been made in Porto Rico to canvass this industrj^, consequently there were no initial data available to aid in the present study. It ^Bu.shels. was known, in a general way, that bricks were made in the island, also that no modern machinery was utilized in their manufacture. That the industry was not extensive or important was quite evident from the absence of brick editices and the almost universal use of lumber in the construc- tion of dwelling houses, except in the cities of San Juan, Ponce, and ]\Iayaguez. This first inquiry, therefore, could not be other than crude and incomplete, bj' rea- ,son of the following facts: (1) No previous statistics existed showing establishments engaged in the indus- try; (2) brickmaking was not engaged in continuously by anj^ one establishment, ovens being baked, from time to time, as the necessity demanded; (:3) lack of precise information on the part of the operators them- selves as to number of bricks made, their actual cost, average .selling price, etc. For the foregoing reasons it is apparent that many persons who engage in the manu- facture of brick as occasion therefor arises could not be reached at all. In the brief period at the disposal of the writer it was not possible to ascertain the loca- tion of more than .']•'> operators. Of these, .30 were suc- cessfull}' interrogated, with the results shown in the following- table: Clay products: 1902. LOCATION OF OFFICE ANI> FACTftRY. COMMON BRICK. KILNS. NAME OF OWNER. Department.

Whenever the demand is such as to make the produc- tion of an oven of lime sufficiently lucrative the farmer will prepare one and take it to the nearest market. The production of lime in Porto Rico, therefore, is impor- tant rather by reason of the large number of persons engaged therein on a small scale than on account of commercial importance. A certain amount of lime is used bj' the sugar factories to clarify sirup. In response to interrogatories as to quantity and cost of the lime thus used at the more important factories in the course of a year, the owners stated that where the lime was not to be had on their own premises it was usually obtained from some neighboring deposit gratis. The limestone formations may be divided into two classes, white and yellow. There are also deposits, few in number, of a blue limestone, somewhat resem- bling granite formation, and of nuich harder composi- tion than either the white or yellow varieties mentioned above. PHOSPHATE ROCK. There are four phosphate rock mining claims regis- tered in the office of the Commissioner of the Interior of Porto Rico, none of which is being operated at present, viz: ReqiKtered iiriviriij di'iiiiix of j)Ji(_mj>}iaU rocJ^. locj\-tion of mine.

This deposit was formerl^r operated on an extensive scale and the product shipped to Germany. It is idle at the present time, however, pending action hj the executive council of Porto Rico upon a franchise to work the deposit, for which appli- cation has been made. In statistics previously compiled on this subject, deposits of bat guano have been con- fused with phosphate rock in consequence of such guano being found upon rocks or in caves of a phosphatic character. GRANITE. It is not believed that any real granite isto be found in Porto Eico. Two residents of the central section of the island claiming to have discovered granite on their premises gave the information that only 18 cubic meters (24 cubic yards) had been sold in the rough for curbing purposes and 81 cubic meters (106 cubic yards) crushed for roadmaking purposes. It is probable, however, that the stone in question is of dioritic formation and not granite, as they allege. MINERAL SPRINGS.

The Florencio springs are not operated for the benefit of the public. There is a private bath house used by the faiuily of the proprietor and by other persons by special piM'mission. The waters have nevm- been bot- tled nor put on the market. The proprietor states that local ph_ysicians prescribe the waters foi- -skin diseases and stomach troubles, but that a scientific analysis has never been made. PORTU RICO— LIMESTONE QUARRIES. POIITO RICO. 1085 The Quintana springs, near the town of Ponce, are also quite extensively known locally as possessing excel- lent medicinal virtues. The waters are administered in the form of baths, but within recent months, owing to the bad state of the road leading to the baths and tlie abandoned condition of the establishment itself, the springs have ceased to be a public resort.

The Arro3'o springs are not operated by the j^roprie- tors, who state that no trustworthy analysis of the waters has as j'ct been made. Accompan3dng this report is a map showing approxi- mately the location of mining claims, salt deposits, and mineral springs in Porto Rico. Owing to the fact that no scientific triangulation or survey of the island has ever been made, it has been impossible to indicate on the map with exactness the geographical position of these claims. It is believed, however, that the general purpose of showing the approximate location of the mining deposits of Porto Rico is sufliciently well served. The reason given above with respect to the want of exactness in the location of mining claims applies to the boundaries separating municipalities as well. Ever\f effort was made to obtain data showing the number of persons emplo3'ed during the year in the exploitation of the mineral resources of the island. For obvious reasons such an efl'ort could not meet with anj- great degree of success. As has been stated, in no case were mines or quarries operated during the year as a continuous industrial enterprise. Even in respect to such woi'k as brickmaking, lime burning, or quarrv- ing, operations were of an intermittent character. An regards (juarrying, the rock was usually taken out by the contractor's cmgaged upon road construction or repair in connection with their other work. No amount of research, therefoi-e, would have permitted a definite statement either of the total output or of the number of persons employed. 'Jlio best that can be done is to make a rough estimate, based upon the general informa- tion soeurod, in obtaining the data for the report of the probable average number of persons that ma}' be said to have gained a livelihood in some capacit}' in connec- tion with the exploitation of the mineral resources of the island. In respect to the extraction of precious metals, a fair estimate would put the average number of men con- stantlj' employed during the year in exj^loitation work for gold mines and the la_ying out of claims and similar work at twenty-five. Thirty additional men were prob- ablj' employed in placer mining, chiefly in the Corozal district. Exploitation and field work in connection with copper mines probably did not engage more than ten men. About one hundred and fiftv men ma}' be said to have been constantly employed in the operation of salt mines. Brickmaking probably gave employ- ment to an equivalent of two hundred men working all the year. Estimating from the amount of limestone extracted for the purpose of roadmaking and repairs and for burning, an exceedingh' rough approximation would place the amount of labor expended in limestone rjuarrying operations at five hundred men. As only 50 tons of phosphate rock were mined during 1902, probably not more than two or three men had constant eniploj'ment during tlie year. That Porto Rico possesses mineral resources that will be of great value to the island in future 3'ears theie can be no doubt. In their utilization the stage as yet has only been reached where efforts are being made to determine more exactly' their character and extent. Authorization for water rights and concessions of various characters are being constantly sought of the insular government, and it is certain that when another investigation along the lines of the present one is made the phase of industrial exploitation in respect to a num- ber of minerals will have been definitely entered upon.

Dear Sir: In accordance with the act of Congress of March 6, 1902, requiring the Director of the Census to prepare a report on mines and quarries, and pur- suant to an agreement between the Director (.f the Census and the Director of the United States Geological Survey, the Geological Survey will collect the data for the mining census, in addition to the usual information collected for the trn- nual report, "Mineral Resources of the United States." The schedule below has been prepared for the purpose of obtaining the statistics of the production of small coal banks which are engaged in mining coal for immediate local con- sumption. Please fill out the replies to all the inquiries and return this sched- ule in the accompanying envelope, which requires no postage. In order that reports from all local banks may be secured, and the canva.s8 thus be made as complete as possible, you are requested to add the names of the owners of any other mines in your immediate vicinity. Your prompt compliance with this request will greatly facilitate the work of both the Geological Survey and the Census Office, and will be highly appreciated. Very respectfully, Chas. D.

By an agreement between the Director of the United States Ceiis^us and the Director of the United States Geological Survey, made to avoid a duplicate canvass of the mining and quarrying in- dustry, and for other purposes, the Geological Survey will have supervision of the field work of the Census of Mines and Quarries. In accordance with this agreement, reports will be secured on both the Census Office schedules and the schedules of the Geological Survey for all mines, quarries, and reduction works in existence during the year 1902. The schedules for the two offices must be forwarded in the same envelope. 2. The agents will transmit all schedules promptly to the Geo- logical Survey at Washington, D. C, unless specially instructed, as will sometimes be the case, to send them to the office of special agents of the Geological Survey in other places. 3. Agents are required to comply with all the regulations of the Census Office governing field work and to submit daily reports on the blanks prepared for that purpose. The names of establish- ments for which returns were secured, and also of those visited but for which reports were not obtained, nmst appear im the re- port for each day. The agents must, also, under "Remarks," state the character of the mineral for whicli they are securing re- ports and keep the office advised of the probable date on which they will complete their present assignment. Daily reports will be promptly transmitted to the Census Office through the Geolog- ical Survey and the relative efficiency of each agent determined therefrom. 4. Each agent will be furnished with a list giving the names, locations, and addresses of all mines, quarries, etc., assigned to him, which were in existence during the year ending December 31, 1902, together with a list of tliose for which returns have been obtained by correspondence. This list has been prepared from reports made to the United States Geological Survey in previous canvasses, amended by information received from other sources. The list, however, may not be entirely complete, and the agent, therefore, must be constantly on the alert to discover other mines or quarries. They must make careful inquiry at each city and town they visit for mines and quarries located in that vicinity. If such plants are discovered, and they are Icjcated in the territory assigned the agent, he should proceed to secure returns for them m the same manner that rei)orts are secured from establishments on the lists. In forwarding the rer>orts for unlisted mines . If two or more items of rent are paid in one sum to the same party, give the amount paid and state for what it is paid. L^'(^^■IRY 10. — Proihct, Gross value ofmelaUic roiitents, ar value. The "authorized" and "issued" stock should be reported in all instances. The amount of dividends, if any, paid during the year on com- mon and preferred stock should be the result obtained by multi- plying the par value of common and preferred stock issued to the end of the year by the "rate" reported. If the amount is reported and no rate, the rate shouW Vie calculated and supjilied, and vice versa. A report showing bonds should show the rate of interest on the same, although no interest is reported as paid. In cases where an incorporated conjpany owns more than one mine or quarry and a Special Schedule No. 6a has or has not been filled out, it frequently occurs that the details of capital stock and the general officers are included in each of the individual sched- ules, thus duplicating and triplicating, etc., this information. In all cases of this kind, after being assured that an ajiportionmcnt of the capital stock, etc., has not been made among the individual schedules, the duplicated data should be stricken off all schedules except one and a note substituted to the effect that the informa- tion is reported on Schedule (giving the name of the mine and location). Inquiry .? — Personit eniployrd. — The information reported uniler this inquiry should be very carefully examined, and the three sec- tions of the inquiry should agree with each other and with other inquiries that have the least bearing upon the question of employees and wages. The numbers of the several classes of employees reported should not be out of proportion with each other, nor with the character and extent of the mine or quarry reported on the schedule. No employees should be reported "below ground" for quarries or surface mines. The average number of "wage-earners," which includes all classes of employees other than general officers, superintendents, managers, etc., and clerks reported in the first section of the inquiry, should agree in number with those reported under "Wage- earners at specified daily rates." The total average numljer of wage-earners under these two sections of the inquiry should accord- ingly be written in the margin of the schedule. The total wages reported for all employees after clerks, e.xcept foremen "below ground" is the amount of wages to be used in comparison with the second section of the inquiry. This amount should be written in red ink in the margin of the schedule. The wages that would be earned by the employees reported at specified daily rates, at the rates given, the mean rate being used in the calculation, and for the time in operation as reported under Inquiry .5, should agree approximately with the amount reported under the first section of the inquiry. This comparison should l)e made for the entire number of wage-earners and for each corresponding class of wage- earners. To obtain the average number of wage-earners during the year, reported under "'Average number of wage-earners employed during each month," add the numbers reported for each month and divide the total by 12, the numljer of months in the year. This calculation should be made on the left-hand margin of the schedule in red ink. The average number employed during the year, under the first and second sections of Inquiry 'i, must be the number that would be required to produce the quantity oi product reported, working continuou.«ly for twelve months. Therefore, if a mine or quarry had suspended operations for any protracted length of time during the year, the average number of wage-earners, under the first and second sections of Inquiry 3, must be reduceil by that proportion of the number reported that the period of iilleness is to twelve months, providing the average number as reported in answer to these sections is approximately the same as the average number employed during each month the mine or quarry wa,s in operation. When necessary to make such reduction, the amounts paid in wages to the several classes of employees must be approximately the amounts they would receive if employed the full number of working days in the year at the specified daily rates of pav, and not the amounts they would receive for the actual number of davs employed at the rates reported. The reduction of the average numl)er of emjiloyees that may be necessary should not always be applied to "Sui>erintendents, managers, etc.," "Clerks," and "Engineers, firemen, etc.," as these employees generally work full time whether the mine is idle or in operation. However, if the computation shows that they were employed only while the nune was operated, the reduction should be applied to them the same as to the other employees. There should be a substantial agreement in the rates of wages shown on the different schedules from establishments engaged in the same branch of industry in the same localitv. Inqviry 4. — The information reported under this inquiry should be reported also under Inquiry 3. The number of employees and amount paid should be included in Inquiry 3, under "Miners or i|uarrymen and stonecutters" for surface mines or quarries, and under "Miners" and "Miners' helpers" for underground mining. The inquiry is intended to develop the manner of pa3-ment for the actual work of mining or quarrying when not done by the day. As there is not frecjucntly a diversity in the method of payment for identical work in the same mine or quarry, it is thought that the data reporteil as to the average nund.)er of emplovees and total APPENDIX C. 1115 amount paid in this inquiry will, in moat cases, l)e the same as that reported under the heads provided^ for this iiiforniation in Inquiry 3. Inquiry 5 — Time in operation. — The information reported under this inquiry should be considered in connection with the answers to Inquiries 3 and 9, and in verifying the amount reported as paid in wages by the specified daily rates and the number of wage-earners reported at each, the number of days in operation, and the numlier of shifts of workmen reported under this inquiry should be taken into account. The number of shifts of workmen reported will be one in the large majority of t'ases, and sometimes two or three. A larger number of shifts is open to question. In quarrying and sur- face mining if more than one shift is reported it is questionable. This is also true of certain other branches of nuning. The number of hours to a shift will in most cases be 10, frequently 8, and some- times 12. Inquiry 6 — Contract tvork. — The information reported under this inquiry is entirely separate from any data given under Inquiry 3, and should not be included therein. It is frequently the custom to let such work as tunneling, shaft sinking, boring, etc., out by contract, and no record is kept by the officers of the mine or quarry of the wage-earners employed and the wages pairl, and as it is in most cases impossible to obtain the information from the contractor, it will be estimated and given by the mine or quarry operator. Contract miners or quarrymen who work by the ton, car, yard, etc., should not be reported under this inquiry but under Inquiries 3 and 4. Inquiry 7 — Supplies and materials. — The character of the expendi- tures to be reported under this inquiry is shown on the schedule. It should always be considered in connection and compared with the product reported and answers to other inquiries. Except under extraordinary circumstances, the amount reported will not be in proportion to the value of the product. It will frequently be found to be the case that no amount is reported under this head, particularly in very small mines or quarries, and in such cases it should be accepted as correct. It is frequently the case when the crude mineral is put through a process of milling, refining, calcining, or other manufacturing at the mine or quarry, as gypsum, limestone, and cement quarries, that crude material is purchased from other mines or quarries that are not equipped for such work. The quantity and cost of mate- rial so purchased should be separately reported under this imjuiry. Inquiry 8 — Miscellaneous expenses. — All items of expense incident to the operation of the mine or quarry, not accounted for under Inquiries 3, 4, 6, and 7 must be reported under this inquiry. Care should be taken that the royalties for mineral taken out from leased land and other forms of rent for the mine or quarry be reported separately under the first item of this inquiry. It will be frequently found to be the case that no amount is reported under this head, particularly in very small mines or quarries, and in such cases it should be accepted as correct. Inquiry 9 — Proc/?/rf.— Inclosed with each schedule will be found a copy of the card of the Geological Survey containing a detailed report of the product. The product as reported on this card, and not as entered on the schedule, will be tabulated and included in the published reports. It will, therefore, be taken as the product in editing the schedules when considering its relation to the data reported in reply to the other inquiries. This question should receive very careful exammation and be carefully compared with the replies to other imiuiries. The quan- tity reported should be consistent with the number of employees and the time in operation; the kind of mineral, and the conditions of mining it should also be considered in this connection. The value per unit of the product should be examined to see that there is not a very great difference between the average value shown in the schedule and the average ruling price of the article under lon- sideration during 1902. As it is necessary that the quantity and value nf tlie product pubhshed in the reports of the Census Office and in tliose of the (Tcological Survey agree, under no circumstances should any change he mailc in this information without the permission of the section chief. Inquiry 10 — l'oirei\ — The first consideration in examining this question is as to whether or not the use of mechanical power is required. This question is determined by the size of the mine or quarry, and by the character or method of mining. In a very large mmiber of quarries and open mines generally, no power is used, lint if they an? of considerable magnitude some equipment for power purposes is necessary. In a large majority of cases the power reported will be steampower. Before closing any branch of the mineral industry, and taljulat- ing the schedules, the files should be searched and all No. 6a schedules withdrawn. The information reported under Inquiry 6 siiould then be carefully checked against the individual mine and quarry schedules to see that all the schedules are on file. If the mines or quarries are all located in the same county, the data reported on the No. 6a schedule should be added to any one of the individual schedules and an examination made of the others, for the purpose of eliminating this data, if duplicated on such schedules. Care should be taken that all information under Inquiries 1 and 2 be stricken off all schedules, except one, and a suitable cross reference made to the schedule containing the infor- mation. If the mines or quarries are located in different states or counties, or if there is more than one branch of mining, the data on the No. 6a schedule should be apportioned among the different states and counties, or branches of mining, as the case may be, the apportionment Ijeing based on the value of the product. INSTRUCTIONS FOE EDITING SPECIAL SCHEDULES. The foregoing instructions are intended for general application in editing the returns of mines and quarries of all kinds. In addi- tion, there are certain special schedules which contain peculiar features and require further explanation. Special Schedule No. 8 — Coal Mixes. Inquiry 3 — Persons employed. — Care should be taken that the employees are correctly reported "above ground" and "below ground." Only an insignificant proportion of coal mines are sur- face mines, and in such cases the mines should be reported under. Inquiry 14 as "Open cutting or stripping." Eoughly stated, in bituminous coal mining, about nine-tenths of the entire force of employees work underground, but in anthracite mining, on account of the large plants on the surface for screening and cleaning the coal, the proportion underground is less than in soft coal mines, being about two-thirds. The timl^ermen and track layers separately stated under the sec- ond section of this inquiry should be included among "All other employees" below ground, in the first section of the inquiry. Inquiry 4 — Average number of employees and rates paid. — As the actual work of coal mining is seldom done by the day, the number of miners and miners' helpers, with their earnings, should be re- ported here. This information should also be reported under the first section of Inquiry 3. Under the second section of Inquiry 3, where miners are paid by the ton, car, or yard, the specified daily rate under which those contract miners are reported should be the same for the entire number of this class of workmen. This rate should be estimated by the examiner from the total number of days in ojieration and total amount of wages paid, and should he the average daily earnings for the period that they are employed. The "Total amount paid for such work" should agree with the amount reported as paid to miners and miners' helpers under Inquiry 3, and this amount should include the amount reported as paid for vardage or other allowances. As reported on this sched- ule, these all(5wances are frequently not included in the amount paid for mining. This may be verified by calculating the amount that would he received on the product reported, under Inquiry 9, at the 1116 M1NP]S AND QUARKIEB. rate given under Inquiry 4, and if it is found that the auK lunt is udt included it should be added, the correction l)eing made in red ink. Inquiry IS — Contract n'orl;. — Care should be talvcn that the infor- mation given under this inquiry is not duplicateil under Inquiries 3 and 4. It is probable that in only a small proportion of the schedules will information be given under tiiis question, l)Ut, when reported, it should lie treated as separate information not included under any of the other inquiries. In calculating the expense of operating the mine foi' the purpose of comparison witli the value of the product, the amount reported as paid f(ir contract work should be added to tlie other expenses for wages, supplies and materials, and miscellaneous exiienses. When an amount is reported as paid, tlie "Average number of men employed" and the "Number of days" should also be reported. Inquiry 8 — Royalli/ and rent of mine. — In examining this inquiry, reference should also be made to Inquiry 16, and if any rate is given, an amount should be reported under Inquiry 8 as paid fcjr royalties. This amount need not necessarily be the amount obtained from calculating the royalty on the number of tons reported mined under Inquiry 9, by the rate given under Inquiry 16. It can in no case be more, but may be less. Royalty is fre- quently paid on only a part of the product of the mine. It should be borne in mind that while the product is reported under Inquiry 9 in short tons, royalty is frequently paid in long tons. This is also true of Inquiry 4, the miners being paid for long tons and the product marketed in short tons. The general instructions apply to other features of Inquiry 8. Inquiry 9 — Product. — The data reported under tins inquiry should not be inconsistent witli information given under the other (jues- tions on the schedule. In bituminous coal ndning the quantity of coal taken from the mine will ggree in most cases w-ith the market- able coal reported. If no information is given as to the number of cars of coal taken from the mine and the average capacity of such cars, the information should be supplied on the basis of the infor- mation given in other reports of mines in the game locality. There will sometimes be a difference shown in the reports of bituminous coal mines between the quantity of coal hoisted and the quantity of marketable coal. In anthracite coal mining, owing to the larger proportion of coal which can not be utilized, the differ- ence between the coal taken from the mine and that marketed will in many cases be considerable, the latter being less than tlie former. This is the result of the crushnig, screening, and cleaning processes by which the coal is prepared for shipment. Inquiry 10 — Power. — In all large mines power in some f(jrni should be shown. The purposes for which it is required are for operating the crushing and screening machinery, for hoisting, pumping, and ventilating, and sometimes for other subsidiary pur- poses. A knowledge of the conditions found at coal mines is gen- erally nece.ssary to properly edit this question. If the opening to a vein is a shaft or slope, a hoisting engine will be re(iuired and in all probability one or more pumping engines, and if fan ventila- tion is employed, an engine will be necessary to operate the fan. Other methods of ventilation do not require the use of power. Inquiry 11 — System of haulage. — The information re(juired under this inquiry is where a mechanical system of haulage has supplanted to some extent the use of animal power, such as horses and mules. It does not apply to the mechanical power used for hoisting coal from a shaft or slope. Inquiry 1.! — Slnle pickers or coal cleaners. — This inquiry is intended to apply only to anthracite mines. In separating the slate from the coal mechanical means have been substituted to a very large extent for boys, and the object of the inquiry is to determine the magni- tude of this change or improvement in anthracite mining. Inquiry IS — Washeries. — This (juestion also is intended to apply only to anthracite coal mines. The u.se of washeries for cleaning coal, which formerly was allowed (o lie on waste dinnjis, is compara- tively a recent development, and by the use of such washeries a uiuch larger proportion of the coal mined is available for shipment. Wherever awashery is reported under this inquiry there should he a separate report in the files giving the operations of the washery. Inquiry 14 — Openings to tlw works. — A\'henever a shaft, slope, (jr tunnel is given as the nature of the opening to the vein, its depth or length in feet should be given. This information is not reijuired where the mining is by drift or open cutting or stripping. Inquiry HI — < 'ikiI mined on royalty. — If any rate is reported under this question, corresponding information should also be reported under the first ilenj of Imjuiry 8. -;f -/.- -;<- -X- * Special attention sh(.iuld be jjaid In the reports of bituminous coal mines where coke is manufactured. Tiiis information will be found on the slip containing the (ieological Survey details of pro- vluction. Oidy the capital stock, general officers, expenses, etc., pertaining to coal mining should be included in the schedule. If any of these data pertaining to I'oke manufacture are included, a ■ieparation shoulil be made, based on the relative proportions of the two branches of the business. (iOLD, SILVER, LKAI), AND COPPER MINES. In editing Special Sche)itained from the lessee and another from the owner, and both .schedules should be combined; one should be marked " fawner's report," the other "Lessee's report." The owner should, in such cases, report i'ai- IHOli separate reports are required from each owner or lessee for the time he operated. These reports should be combined, but all repetitious should be elinnnated from one of the schedules. (See Inquiries 13, 14, 15, and 1(1) 2. Snndl and Cliinese mines. There are a number of schedules marked " Small and Chinese" with nothing but an estimated value of the jiroiluct. All such schedules should be assorted into a ."eiiarate grcmp to be taliulated on a separate sheet. 3. dene rid office. The address of the general office nuist be given on the title page of the Census sidiedule and also on the United States Geological Survey transfer slip (Schedules Nos. lOa and 10b). Very fre- quently the address is given on the I'nited States Geological Sur- vey transfer slip alone; in such cases it should likewise be written on the title page of the Census schedule. If no general (jffice is maintained sejiarately from the mine, write in red ink after the words "general olHce" the w(jrd "mine." APPENDIX C. 1117 4. — Preliininarif rlassificalion. i All Schedules No. 10 should lir classitied under one of the fol- lowing four groups; First. Productive. Second. I>evelrk must in such cases be equal to the total amount expended and need not be re- ported separately. If it is so reported it should be erased. Very frefiuently the amount reported under this inquiry is equal either to the total wages and salaries or to the total wages alone, or to the sum of wages, salaries, and suiiplies, or to the sum of wages and •supplies, or to the amount paid for contract worli . All sucli an- swers should be erased. If, however, tlie amount rejjorted is either in excess or short of any of these quantities, the schedule should be criticised; in the former case it may eventually disclose an omission under Inquiries 4, 7, or s, or the amount may repri'sent the expenditure of more than one ye;ir. Among the schedules of this class a number will be found where nothing but the amount expended in development work is rejiorted; they proliabl\" i-c]irc- serit merely assessment work on more than one mining claim in each case. All .such schedules should be segregated into a separate gr( lU]). In njany cases the work was done by the owner and his family ajid till' amount reported is an estimate of the value of his labor. Such schedules should likewise be segregated into a separate grouj). (See further instructions to Inquiry 4.) If the value of the development work done in such cases is esti- mated, write in the blank space, after "Amount expendeil in de- veloi>ment work," the words "Done by owners." In case development work is done in consideration of a lease and the amount is estimated, write similarly, "Done by lessees." Aside from these instructions all schedules of this cla.-'S are to l>e edited in accordance with the general rules applying to the Mining Census. 2. PriidiirUri' lainen. The ftained, the amount reported on Schedule No. 10a should be entered on Schedule No. 10 as ".Net value of the mining product." B. IIEEP .MINES. Srhedide Na. 10a — Inquiries I, 2, am! .1. — There should be a com- plete answer to these three in(|uiries. If the total quantity of ore mined in 1902 exceeds the tohil quantity solang, the state and county, should tje made and delivered to the e.rpert special agent in charge. Usually the treatment charges include also discounts. If the latter are not reported separately no segregation should be attempted, but the amount should stand as reported. In some cases the treatment charges include freight charges. The amount reported should be allowed to stand; no segregation need be made. Freight ctiurges. — These include the cost of packing and haulage by team and railroad freight. When the two items are reported separately, they should be allowed to stand. Charges and freight per ton. — Besides the total charges, the inquiry calls also for charges and freight per ton. The latter can be given only when everjf shipment of ore was treated at one establishment. It freijuently happens, however, that the ore is first concentrated at a custom mill and the concentrates are then shipped to a smelter. The tonnage shipped to the mill is then quite different from that shipped to the smelter; average rates per ton would in such cases be misleading and should be erased. All such schedules should, be referred to the expert specicd agent in charge. No charges. — In many cases the full value of the gold and silver contents of the ore is jiaid to the operator, no charges whatever being made fijr treatment and freight; this is when the ore contains a high percentage of iron and manganese, which are not paid for. Sometimes the percentages of iron and manganese are so high that a bonus is paid to the mine operator, besides free treatment and freight. The amount of the bonus should be entered on Schedule Xo. 10a, Inquiry 4, as the value of the iron or manganese. NET VALUE OF TJIE MINING rRODUCT. The net value of the mining product is equal to the gross value less the deduction for treatment charges and freight. In some cases the question was misunderstood, and the net profits were reported instead of the net value of the product. The amount should he properly corrected. In many cases nothing but the net value of the mining product is reported liy the operator; it is when the ore was sold "at a flat price per ti.m." In such cases, if the metallic contents are reporteil on Schedule No. 10a, Inquiry 4, the total value, as calcu- lated by the United States Geological Survey, should be accepted as the "gross value," the net amount received by the operator as the "net value," and the difference should be entered under "Dedu(.'tions." 1120 MINES AND QUARRIES. niGII-ciUADE AXI> LOU-GRADE ORES. Scliedule No. 10a, hiquinj 11. — Divide the total contents of i;old and silver given umler Inquiry 4 by the total quantity given une computed. If the number of mineral claims is reported, the acreage should likewise be computed l)y multiplying the number of claims by the average size of the idaini as determined by law. If the rejiort shows no land owned and some held on lease, a note should be made on the title-page, in the upper right-hand margin, reading "lessee's report." VII. Reduction Works. Reducti(jn works have been ilivided for census purposes into smelters and reduction works other than smelters, or mills, the former being reported on Schedule No. 12, the latter on Schedule No. 11 and 11a or lib. All smelter reports must be referred to the expert special agent in charge. In some cases smelters were erroneously reported on Schedule No. 11. Such schedules should likewise be referred to the expert special agent, together with all Schedules No. 10 relating to mines connected with smelters. All mills are t( i be divided for tabulation purposes into two clas.ses, (1) mills without mine connection, commonly designated as " cus- tom mills," and (2) mills connected with mines. A. custo.m mills. Reduction works, other than smelters, without a mine connection are reported on Schedules No. 11 and No. lib. Inquiries 1, 2, 3, 7, and 11 are substantially iilentical with In- quiries 1, 3, 6, 8, and l.^, respectively, on Schedule No. 10. (See instructions above. ) Inquiry .? on Schedule No. 11 corresponds to Inquiry 4 on Sched- ule No. 10, except that the division " below ground " is absent. Inquiry S on Schedule No. 11 corresponds to Inquiry 9 on Sched- ule No. 10, with the omission of " development work," and of the detailed inquiry into rent or royalties. Inquiry IS serves the same purpose as Inquiry 11 ores bought bv tlie null. The gross value of the mill product is reported on Schedule No. lib, under the head of " Proilnctiou," and transferred therefrom to AI'PENDIX C. 1121 '^'iniry 9 on Schedule No. 11, as " Rross value of metallic coiitcnlH •IS re]i,,r^g^^ iQ ^\^^. (Jeological Survey." The incjuiry is S(i wnrdcil SIS to inchide both the product of j/urr/Mi.sci? orr.sand of (hose Ireiilnl for riisfoiaa-.i' accouni. In actual practice, however, few iiiillH re- ported the product of custoui ores, stating; tluit the liullinii or cdii- centrat.es were returned to owners and no record thereof \v;is l;ept at the works, except the tonnage treated and the amount received for treatment. In those few cashes where the contents of custom ores are given they are confessedly more or less loose estimates, with hardly any excejitions. For the sake of uniformity of re- sults nothing but the product of purchased ores should be allowed to stand under the head of production. In case no ores were purchased the fact will appear from the an- swer to Inquiry 6 on Schedule No. 11. In all such cases the total quantity under " Production" on Schedule No. lib iimst be iden- tical with that reported under Inquiry 10 on Schedule No. 11. The "total yield in gold," "total yield in silver," copjier, lead, and other metals, if reported, should be crossed out and the word "None" should be inserted; likewise should the word "None" be inserted under Inquiry 9 on Schedule No. 11. But the same amounts under "sources of materials treated" should not be disturbed. In case the mill handled both purchased and custom ores, a comparison of Inquiries 6, 9, and 10 on Schedule No. 11, and "pro- duction" and "sources of materials treated" on Schedule No. 11a will assist in determining the product of purchased ores alone. In case of uncertainty a request for correction should be sent. For particulars in relation to the several items of the yield frf)m purchased ores (gold, silver, lead, copper, etc.), see instruction above for mining product. Treatment and freight chargex. — The milling product rei|uires fur- ther treatment at a mint, refinery, or smelter. Usually the pro- duct is sold, sometimes it is treated on tolls for the account of the mill owner. In the former case the deductions from the gross value of the product should be reported under Inquiry 9, in the latter case under Inquiry 5. Sometimes the same amounts are duplicated under Imjuiries 5 and 9. In such cases it may be safely assumed that the product was sold, and the answer to Inquiry 5 should be erased. When no purchased ores were treated at the mill, the answer to Inquiries 5 and 9 should be "None." For further particulars see above in- structions for " Mines." CUSTOM WORK. Schedule No. 11, Inqulri/ 10.— The "amount received" should represent the mill charges for the work of the null, not the value realized by the customer from the sale of his bullion. Sources of material treated— Schedule No. llh.—ln a very fen- schedules this inquiry has been answered. Tlie answer should be supplied at this office. Transfer the tonnage and values given un- der "Productions" to Inquiry B, on the reverse side of Schedule No. lib, entering the same under "Total domestic."

MI.NIOS COXNlOfTHI) WI'I'II REDIK TION W(]|tKS. In accordance with tbc^ classilication of reduction works into ".Hnicltcrs" and "other than smelters" (mills), mines will be found ciinnected willi smelters or mills. The iiiiiiilicr of juiiirx converted irilli. suirlters is rery limited. The reports fcjr sucli mines should be attached to the smelter reports ami leferred to the expert special agent for separate treatment. Where a mine and reduction works are r)perated under the same manageuient, separate reports were requested for each on Schedules Nos. 10 and 11. But where this was not possiVjle (be- cause the accounts for the mine and the mill were not kept sepa- rately) one report was requested covering iioth the mine and mill. Inquiries on Schedule No. 10 were to be answered, except Inquiry 10, ane confined to the product treated at the mill. All such schedules must be segregated into a separate group 4. Calculations. The answers to the following inquiries on the back of Schedule No. 11a must be supplied at this office: Inquiry 1. — Bullion contents and gross value per ton of ore mined and milled. If the bullion is all from ores mined by the same company, divide the bullion contents of the precious metals, given on Schedule No. 10a under Inquiry 4, by the total amount of ore treated, given on Schedule No. 10a under Inquiry 2; the result will give the nundier of fine ounces of gold and .silver per ton. Divide the total copper, lead, and other base metallic contents by the same tonnage treated, and further divide the result by 20; the quotients will give the percentages of lead, copper, etc., in the ore. Divide the total value given under the .same head by the same tonnage; enter the quotient under aggregate gross value. Inquiry S. — It the IjuUion is partly from ore ujincd by the com- pany, partly from purchased ores, the quantities and values given on Schedule No. 11a must exceed those on Schedule No. 10a under Inquiry 4. Deduct the latter fnjm the former; enter the differences in the first and third columns, respectively. Divide the amounts entered in the fir.st coluuin by the total ton- nage reported on Schedule No. 11a under Inquiry 6; divide fur- ther the figures for base metals by the number 20; enter the resuhs in the second column. Divide the total gross value of tlie third column by the same tonnage and enter in the same column on the line intended for ' ' average per ton. ' ' Similarly, divide the "total assay contents" and "total gross value" reported on Schedule No. 11 under Inquiry 6 and enter the results in the fourth colunm. Inquiry 6. — Copy the items entered on the face of this schedule under "Sources of materials treated in 1902." Add separately all domestic and all foreign material and enter the totals on this schedule. All schedules reporting foreign ores treated must be brouglit to the attention of the expert special agent. .5. Flnrers villi siamp mills. As a rule, only the product of deep mines requires further treat- ment at reduction works. The product of placer mines is gold dust or amalgam, which can be sold to a United States mint or assay office, or to a private refinery. In some cases, however, the placer ground is cement, which must be crushed in order to wash out the gold. This is done in a stamp mill. Accordingly, there are a few reports on jilacer mines with reduction works. These should also be segregated into a sejjarate group. 6. Old urine dumps and old mill tailings. A separate class is formed by those mills which treat low grade ore from old mine dumps or old mill tailings, which could not be profitably treated with the old methods. In every case of this kind the report on Schedule No. 11 and lib should be supplemented by one on Schedule No. 10, giving the rent or royalties under Inquiry 10. These supplemental schedules must be prepared at this oflice. Where the method of treatment is concentration, a Schedule No. Ua should also be prepared in the manner indicated on a subse- (|uent page. The reports tor old dumps and old tailings should be assorted into two separate groups. INSTRUCTIONS FOR VERIFY! N(j AND (J0RREC:TING THE LABOR AND WAciE INQUIRY ON THE MINING SCHEDULE. An a general rule, the amount of wages and the specified daily rates reported should be accepted as correct. The main object of the revision of this inquiry should be to harmonize the average number of wage-earners, as returned in the several classes under No. .3, employed during the year and the average number of wage- earners at specified daily rates of pay with the amounts reported for each class of employees, the rates of pay, and the time employed. In revising the number of wage-earners of the several classes the following rules should be followed; Multiply separately the minimum and maximum of each daily rate under which employees are reported by the number of em- ployees; then multiply each product obtained by the number of days in operation. The results will show the lowest and the high- est amounts that could be received as wages. The results obtained by this calculation should be compared wiih the amount of wages reported for each class of emjiloyees under the first section of the inquiry. It the computation shows that the amount of wages reported tor the different classes is within the maximum and minimum, the number of each class of employees .should l)e considered as the cfirrect average number for the time in operation. If the schedule is properly filled out, the nuninmm amount (aa derived from the above computations) can not be more, nor the maximum amount less, than the actual amount of wages as reported in the first section of the inquiry. Frequent exceptions to this will be found in the class of engineers, firemen, machinists, etc. These employees usually work full time, and there should be no revision of the average number if the amount of wages reported is equal to the amount obtained by the computations of the mini- mum daily rates multi|ilied by 300 daj's. If the amount of wages reported is less than the result oljtained by this computation, the revisirm should be made in the usual manner. The average number of miners, quarrymen, boj'S, and all other classes of wage-earners, however, should in all cases be revised to agree with4he daily rates and the number of days in operation, gi^•ing due consideration, of course, to the fact that certain classes of employees, as a rule, work a larger number of days than others, jiarticularly if the mine does not work tlie entire number of days in the year. In reducing the average number of each class of workmen to the average by the year, the liasis on which the reduction should be made is the number of days in operation. Having ascertained the average number of each class of workmen for the number of days in opteratioii, llris number should he reduced in the proportion that the num- ber of days in operation is of the entire number of working days in the year, which siiould be considered as 300. The following is an exam- ])le: Number of quarrymen and stonecutters reported, 6, which is the average for the number of days in operation, 2.50: ^'^ x 6 = 5, which is the average of employees for the entire year. Should there be any fractional remainder, the following will serve as an example of the method of revision: Number of miners reported APPP]NUIX C. 1123 98, which is the average fur the number of days in uperaliun, 178: JoJj X 98 = 58.14, or cutting off the second decimal place, 58.1. In all cases where the average number of wage-earners is less than one, the fraction should be preceded by a cipher, as for instance, "0.9." Both in the fir.st and second sections of the wage inquiry the average number of wage-earners should be carried out to one deci- mal place and the corrected figures entered plainly (jn the sched- ule in red ink, the old figures laeing crossed out. This reduction should not be made in the salaried employees. Where the mininunn wages is greater tlian tlie actual wages paid, the average number should be reduced to the nuinlier that, would earn the wages given at the minimum rate; (ir, slmuld the maximum wages be less than the actual wages paid, the average number should be increased to the number that would earn the wages given at the maximum rate. In reducing or increasing the numlier of hands iu tlie second section of the inquiry, specified daily rates, the number to be de- ducted or ailded should be taken from the different daily rates, in the same proportion as the original number at each rate is to the total number of the class under consideration. Another question that should be considered in this connection is the average number of wage-earners employed during each month. As the schedules are originally reported, the number of each class under the first section of the inquiry is usually the actual number employed while the mine was in operation. The average number of all classes of wage-earners for census purposes is the result ob- tained by dividing the total of the numbers reported for each month by 12. An apparent contradiction will sometimes be noted between the numlier of days in operation and the third section of the wage in- (|uiry, showing the average number employed during each month. For example, the full number of employees may be reported for 12 months, while the number of days in operation may be 250. This may be explained by the fact that the idle days were distributed throughout the 12 months, and in such cases the number of days should be accepted as correct, if consistent with the average num- ber of wage-earners and the amount paid. If the number of ilays in operation is in excess of the working days ill tin; number of months reported in the third section, the number of mfinths should be revised to equal as nearly as possible the days in operation. For example, the number of months may have been reported as 7, or 175 days, while the nundier of days is reported as 240. In this case the numlser of months should be increased to 9, or 225 days at 25 days per month. Having revised and corrected the average number of wage-earners in the first and second sections of the inquiry, the average number repfirted each month should be added and the total divided by 12; if the result is different from the total average number of wage- earners, as revised, in the first and second sections, it should be made to agree by changing the average number for each month in the proportion that each is of the total. o y 1' k
