Febkuaky 28, 1891. — Referred to Select Committee on Irrigation of the Arid Lands in the United States. WASHINGTON: GOVERNMENT PRINTING OFFICE 1891. WAE DisPARTMENT, Washington City, February 28, 1891. The Secretary of War has the honor to transmit to the House of Representatives a report from the Chief Signal Ofaoer, M'ith text, tables, and charts, prepared in response to the resolution of the House of Eepresentatives dated May 23, 1890, that — The Secretary of War be, and is hereby, requested to transmit to the House of Eepresentatives the reports that have been prepared under the direction of the Chief Signal Officer of the Army upon the climate of Arizona and New Mexico and other parts of the arid region, together with such tables particularly of rainfall, temperature, evapora- tion, and other matters as relate thereto, with Such corrections, alterations, and additions as may be deemed advisable by the Chief Signal Officer, who will also express his views as to the value and importance of said tables of tempera- ture, precipitation, evaporation, etc., and their bearing upon the subject of irrigation and water storage. The Chief Signal Officer expresses his opinion that the economic value of these reports is such as to justify their being printed by Congress for the information of the public. Rbdfield Prootob, Secretary of War, The Speaker of the House of Representatives, Washington, D. G. Signal Office, War Department, Washington City, February 28, 1891. Sir : Referring to the resolution of the House of Representatives of May 23, 1890, that " the Secretary of War be, and is hereby, requested to transmit to the House of Eepresentatives the reports that have been prepared under the direction of the Chief Signal Officer of the Army upon the climate of Arizona and New Mexico and other parts of the arid region, together with such tables particularly of rainfall, temperature, evaporation, and other matters as relate thereto, with " such corrections, alterations, and additions as may be deemed advisable by the Chief Signal Officer, who will also express his views as to the value and importance of said tables of temperature, pre- cipitation, evaporation, etc., and their bearing upon the subject of irrigation and water storage," I have the honor to transmit herewith text,tables. and charts which illustrate Arizona, California, Colorado, New Mexico, Nevada, and Utah particularly with reference to temperature and rainfall^ together with such other notes on the climatic conditions of the region as appear pertinent and important. Owing to the multiplicity of duties which have lately surrounded the Chief Signal Officer this report has been delayed beyond the time at which he would have chosen to submit it. Even at the present time the Chief Signal Officer has been unable to give it all the personal attention he desired. In view of this fact he delegated to the officer in charge of the records division. First Lieut. W. A. Glassford, Signal Corps, certain portions of the region with which he was acquainted •through residence and meteorological examination. Lieutenant G-las^ford's remarks appear as separate memoirs upon the- climate of Arizona, New Mexico, California, and Nevada. The Chief Signal Officer has treated the subject of the climate of the arid region in perhaps a drier and more practical manner, confining himself to a presentation of such facts and clear deduc- tions as may be of greatest utility to investors and settlers^ as well as of theoretical interest to the 3 4 LETTER OP TRANSMITTAL, more exacting student of irrigation problems. The resulting deductions clearly confirm the Chief Signal Officer's theoretical opinion that the arid regions can not be treated as a climatic unit with , an entire disregard of physical boundaries, and that no general statement or treatment can be outlined which will be of equal applicability in every State and Territory within the region under discussion. The Chief Signal Officer expresses his opinion that the climatic data presented herewith are of great value and importance to any corporation or community contemplating investments in works of irrigation or for water storage, and recommends that they be printed for the general information of the public. Very respectfully, A. W. Greely, Chief Signal Officer. The Seceetaby of Wak. REPORT ON THE CLIMATOLOGY OF THE ARID REGIONS OF THE UNITED STATES, WITH REFERENCE TO IRRIGATION. By Gen. A. W. Gkeely, Chief Signal Officer, U. S. Army. The object of the resolutiOD, in answer to which this report and accompanying charts and tables are submitted, <5alls for a consideration of this question from a standpoint indicated by the Chief Signal Officer three years since. In a previous report to the Senate (on the " Eainfall of the Pacific Slope," etc., Fiftieth Congress, first session, Senate Executive Document No. 91), in February, 1888, before Congress took legislative action regarding the arid regions of the United States, the Chief Signal OflScer pointed out the magnitude of the irrigation question as affecting the future agricultural interests of the population over one-third of the area of the country, and also specifically expressed the opinion that this question could. not be satisfactorily discussed and treated without an accurate knowledge of the rainfall over the area of each particular drainage basin. In treating this subject exhaustively, a large volume could be prepared which would undoubt- edly be of great value as a standard work of reference in connection with tentative enterprises for the development of the natural-resources of the United States west of the one hundredth meridian, but in a report of this kind to Congress brevity is an essential feature, even if the limited time available for the preparation of the accompanying data did not, as it does, impose it upon the Chief Signal OflScer. In answering the resolution, the attention of the Chief Signal Officer has been directed to the States and Territories of Arizona, California. Colorado, Nevada, New Mexico, and Utah. Th6 States and Territories enumerated comprise in their limits those sections of the United States over which the rainfall is the smallest, the prevailing temperatures the highest, the evaporation of moisture most decided, and the amount of sunlight the greatest ; thus presenting, and in some locali- ties combining, such maximum meteorological phases as are of an adverse character to the regular and successful prosecution not only of agricultural enterprises, but, indeed, to the development of any other industry wherewith an abundant supply of water is an essential factor, and for which in these regions the adventitious aid of irrigation is indispensable. The above-mentioned meteoro. logical conditions are less marked and less unfavorable in the remainder of the arid regions, viz, northern California, Wyoming, Montana, the eastern parts of Oregon and Washington, and western portions of Nebraska, Kansas, Indian Territory, Texas, and the Dakotas. It is a serious error and somewhat prevalent that one can predicate the necessity of irriga- tion by simply ascertaining and comparing the annual rainfalls of various localities. It needs no elaborate discussion to demonstrate not only the practical inutility of such comparisons, but also the certainty that deductions therefrom must be nearly always misleading and frequently detri- mental. To illustrate this point may be quoted the annual rainfall of Pittsburgh, Pa. (36.71 inches), and that of Julian, San Diegj County, Cal. (37.68). As these rainfalls are almost identical in amount, it would naturally be assumed by one not conversant with the peculiar distribution ot 5 6 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. meteorological conditions of the United States, which conditions dfepend almost as much on peculiar locality as on latitude, that any industry or pursuit in which rain is an important element would succeed as far as water is concerned equally well at either place. There could be no greater mistake, however, as the following data of average rainfall for Julian, Gal., and Pittsburgh, Pa., clearly indicate. Jan. Feb. Mar. Apr. May. Jnne. July. Aug. Sept. Oct. Nov. Dec. Year. Length of record.

At Julian, however, during seven consecutive months, from the first of May to the last of November, only 9 per cent, of the annual amount falls, while nearly one-half (48 per cent.) of the entire precipitation of the year occurs during the months of February and March. This leads up to the main point, evident to every farmer, that the most important character- istic of the rainfall, apart from quantity, is its proper distribution throughout the year. Over the greater part of the United States the rainfall of the winter months is not of such direct and vital importance to the agriculturists as are the rains of the late spring and of the early summer. This has been illustrated in a report of the Chief Signal OflBcer (see Senate Ex. Doc. 115, Fifty -first Con- gress, first session), wherein he has pointed out that the disadvantages of Nebraska, with a rainfall from one-half to one- third below that of the States of Maryland, New York, Pennsylvania, and the interior of Virginia, are neither as extensive nor as material as might seem evident to one casually considering the effect of the annual rainfall. In this respect the great advantage of Nebraska, and this advantage likewise obtains in parts of Kansas and South Dakota, is in the suitable distribution of rainfall throughout the year, particularly during the mouths of April, May, June, and July, which may be called, not inappropriately, the critical agricultural months from the standpoint of staple crops grown in Nebraska. Ovei" this State as a whole, the per- centage of rainfall in each of these four months closely agrees, that for April being about 11 per cent, of the entire annnal rainfall; that for May, 17; for June, 16; and for July, 16 per cent.; in other words, substantially 60 per cent., or three-fifths of the rainfall for the year falls during the four months mentioned, the period when such nunfall is most needed for the growth and devel- opment of the staple crops. Although the distribution of rainfall in certain portions of the Atlantic coast States is nearly uniform for the different mouths, and although the annual distribution on the Pacific coast is known to be peculiar and marked, yet there has bpen a popular tendency to ignore these widely varying rainfall characteristics and attribute the same. climatic conditions to immense areas with widely differing physical features, and also at greatly varying distances from the ocean, the source of rain. Particularly has misapprehension existed as regards general scarcity of rain and its un- equal distribution throughout the year, since the same rainfall conditions have often been attributed to the entire arid regions of the United States, which by general consensus of opinion cover the entire United States west of the one hundredth meridian. Even among the better informed and casual observers of meteorological conditions, the tendency has been to concur substantially with this popular opinion, excepting so far as it relates to the coast region of northern California, Oregon, and Washington. While the belief of the casual observer aiis to the scarcity of water west of the one hundredth meridian may be considered true in a general sort of way, yet it is not so in many specific and important cases, for the latest rain- fall maps of the United States compiled at the office of the Chief Signal Officer show that there are enormous areas of country in the so-called arid regions where the rainfall exceeds 15 Inches (by which isohyetal, or line of equal rainfall, the arid region is, by some, limited), and even very large areas over which the annual precipitation exceeds 20 inches, and in lesser areas 25 inches. IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 7 The opinion also obtains among many that the rainfall of the arid regions is typically repre- sented by the California rainfall, with a wet season from November to March, and a practically, if not totally, rainless season for the rest of the year. Such a typical curve may not be inappropri- ately represented by San Francisco, where the average rainfall is as follows: January, 5.10 inches; February, 3.60; March, 3.26; April, 1.93; May, O.QJ; June, 0.15; July, 0.02; August, 0.02; Sep- tember, 0.16; October, 0.98; November, 2.87; December, 5.32; year, 24.08 inches; length of record, 42 years. The data show that 43 per cent, of the annual precipitation occurs at San Francisco during the months of December and January, while only 2 per cent., or substantially no rain, falls between the 1st of June and the 1st of October. This peculiar distribution of rainfall, however, is not characteristic of the entire arid region, and it obtains definitely only in California (with slight exceptions) and a portion of Nevada. In Ore- gon and Washington the autumnal rains begin gradually earlier, as one goes northward, commenc- ing nearly a month earlier in Washington, where, however, they cease somewhat earlier in the spring. ^ These peculiarities as to the annual distribution of rain being so marked and varying, even on the bordering coast of the Pacific Ocean, strongly evidence the necessity of a most careful exami- nation of the annual precipitation regime for the rest of the arid region, over which the rainfalls, as a rule, are less plentiful and more dependent on exceptional causes, and consequently more liable to extreme and unusual fluctuations. This examination and comparison the Chief Signal Officer has personally attempted as far as the limited time at his disposal would permit, and the general distribution for different States is shown on Chart No. 1 where the typical rainfall curves are what may be called composite, being made up from selected stations, with long records, in the State or Territory to which the curve applies. The values here given are drawn-from stations selected with reference to their geograph- ical position as well as to their agreement with the common rainfall r6gime, and so may be consid- ered as fairly representative of adjacent regions as well as of their immediate locality. It will appear clearly from these curves, as is more evident by detailed examination of the original data for separate stations, that the varying periods of ^cet* and dry or very wet and very dry months are almost as many in number as the States to which they obtain. These curves also make it apparent that, in order to insure in the arid regions economic and successful crops by irrigation, the growth of only such crops should be attempted or encouraged in different sections as are suited to the character of the local soil, the varying local seasonal temperatures, and which by their seasonal period of germination and development would have the advantage of the rainfall of those months in which the greater part of the general precipitation occurs. The advantage of this plan would be that it thus reduces to the minimum the quantity of water, absolutely essential to the success of the crops, which must be caught, impounded, preserved, and delivered on the ground at a considerable expenditure of labor and material. The general distribution of rainfall throughout the year over the region west of the one hundredth meridian may briefly be defined as follows : January. — This is a very wet month over all of California except the southeastern portion, where it is wet. In Oregon and Washington the coast region is very wet and th« eastern parts of the States wet. It is also a wet month over Nevada and the greater part o f Idaho. It is a dry month over western Texas and the western half of the Dabotas. It is very dry over the eastern half of the two Dakotas, the eastern parts of Nebraska, and over the greater part of Kansas. Over Montana, Wyoming, Colorado (except the eastern half, where it is very dry), New Mexico, and Arizona the amount of preci pitation is either about the proportional amount with reference to annual rainfall, or deviates slightly therefrom. "NoTB. — The terms " wet" and "dry" with reference to months is something more than relative as used in this report. Here it is defined fully with reference to average rainfall, the same rule being followed as has been employed elsewhere. A. wet mouth is one in which 50 per centum more rain falls than the average, and in like manner a very wet month is one in which double the usual amoaut of rain occurs, that is to say, 8.33 per cent, of the annual rainfall is the proportional amount for each month, so that under the definition here given a month with 12.5 of the average yearly rainfall is a wet mouth and one with 16.7 is a very wet month. In like manner a dry month is one in which the average rainfall does not exceed 4.2 per centum of the annual rainfall, and a very dry month is one in which 2.1 per centum, or less, of the annual amount occurs. 8 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. Fehruaru,.— This month is wet over Washington, Oregon, and California (except the soutli- western part of the State, where it is very wet). It is dry over the Dakotas southward to western Texas; elsewhere the rainfall for February shows but slight deviations from its proportional amount with reference to the yearly range. March A wet month for the western parts of Washington, Oregon, and California, A dry month over western Texas, the eastern part of Now Mexico, Nebraska, the Dakotas, arid Montana. - April.— A dry month in the southern half of Arizona and New Mexico with tendencies in localities to be very dry. A wet month in the interior valleys of southern California, over western Colorado and parts of eastern Utah, in South Dakota, and over considerable portions of the Indian Territory and northern Texas. May. — A dry month over the western parts of Washington and Oregon, over all California, the western half of New Mexico, and the northern half of Arizona, and a very dry month, in southern Arizona. A wet month over Texas (except in the neighborhood of El Paso) northward to include the Indian Territory, northeastern Colorado, Kansas, Nebraska, North and South Dakota, Wyo- ming, and the greater part of Montana. However, in northeastern Wyoming, western Nebraska, western Kansas, southeastern Colorado, and the western part of the Indian Territory the month is very wet. Jwne. — The month is very dry over California, southern Nevada, southern Utah, and Arizona, and is dry over western Colorado, northern Utah, central Nevada, and the western parts of Ore- gon and Washington. It is a very wet month over Montana, North and South Dakota, Nebraska, and Kansas. It is wet over Indian Territory, northwestern Texas, extreme eastern Colorado, and all of Wyoming except the extreme southwestern part, and over northern Idaho. July. — A very dry month over California, Oregon, Washington, Idaho, and a dry month over northern Utah. A very wet month over the eastern parts of North and South Dakota, southwest- ern Nebraska, extreme western Kansas, eastern Colorado, western Texas, New Mexico, and the eastern part of Arizona. It is a dry month over western Arizona (except in the extreme south- western part), southern Utah, northern Nebraska, and northern Montana. Augiist.—A. very dry month over California (where it is practically rainless), Nevada, Oregon (where it is nearly rainless), Washington, and western Ida)io. It is dry over eastern Idaho and extreme northwestern Montana. It is very wet over Arizona, New Mexico, and the mountain region of Colorado and southern Utah. It is wet over wes.tern Kansas, the panhandle of Texas, western Nebraska, and the eastern parts of North and South Dakota. September.— Very dry and nearly rainless in California ; dry over Nevada, sonth western Utah, Idaho, southern Oregon, and the greater part of Wyoming. It is a wet month over all of Texas (except the panhandle and southeastern part) and' also in extreme southern Texas, along the coast where the month is very icet. October.— The, month is dry over western Arizona, southern California, southern Nevada, and in portions of the interior of southern Oregon and northern California. Elsewhere about the proi)or- tional amount of the annual rainfall occurs. November. — A wet month in western parts of Oregon, Washington, and northern California. A very dry month over the panhandle of Texas, thence northward through western Kansas and west- ern Nebraska, and the eastern parts of the two Dakotas; but elsewhere from the one hundredth meridian to the crest of the Rocky Mountains it is a dry month. December. — A dri/ month over western Texas, western New Mexico, Kansas, eastern Colorado Nebraska, North and South Dakota, with a tendency to be eery dry in the extreme eastern portion of New Mexico, extreme southeastern Colorado, and extreme northwestern Kansas. The month is very wet over western Arizona, California, the greater part of Nevada, Oregon, and Washington. It must be clearly understood that these terms, wet, very wet, dry, and very dry, refer not to the absolute quantity of rainfall over the regions mentioned, but to the average monthly quantities with reference to the proportional part of the annual rainfall, that is, if equitably distributed 8 33 per cent, of the year's rain would fall in each month. ' Attention is especially called to the fact that a paper of this kind must generally deal with averages, but in connection with the subject of irrigation it is of particular importance to briefly consider the question of excessive rainfalls and also of prolonged periods of drought. IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 9 In this connection it seems also important to consider the absolute humidity conditions over the arid region, that is, the actual quantity of aqueous vapor contained in each cubic foot of air at or near the surface of the earth. On charts Nos. 2 and 3 are shown typical curves with reference to the absolute humidity of the air, which is expressed in the number of grains of water in each cubic foot of air. In preparing these charts it has been necessary to ignore State lines, as the, distribution of moisture and damp air depends so very largely not only on the contiguity to the ocean, but also on the direction of the prevailing winds and the character of the intervening country over which the wind must pass from the source of water supply. Consequently these typical curves have been drawn for the Pacific coast region, the interior of California, and for Nevada, Utah, Colorado, New Mexico, and Arizona. The important bearing which the prevalence of moisture or dry air has upon growing vegetation is well known, but further than this it has an equally important bearing upon the methods of irrigation, since the drier the air the greater the quantity of stored or flowing water which will be evaporated thereby. As will be noted by reference to these charts, the greatest quantity of water is not found in the same month over all parts of the arid region. In addition to the charts, it appears advisable to make some general statements as to the prevalence of moisture or dry air over the regions under consideration. It is impracticable to draw for general conclusions any hard and fast line as to what constitutes very dry or very wet air, as this question turns on the normal temperatures, which in turn depend materially on the lati- tude, the elevation, and the locality with reference to great bodies of water. In general terms, however, it has been decided for present purposes to consider as very dry that air which contains during the colder half of the year — from October to March, inclusive — less than 1 grain of aqueous vapor to each cubic foot of air over Montana, Idaho, and the Dakotas, and less than 2 grains of aqueous vapor to each cubic foot of air over Arizona and New Mexico, with intermediate conditions for the intervening country. During the six warmer months of the year — April to September, inclusive — the limiting figures have been placed at 2 grains for the more northerly sections named and 3 grains for the more southerly. Under these limitations it appears that there is no very dry air over the arid regions during October, but that over the whole region west of the one hundredth meridian, except in California, Oregon, and Washington, along the coast region of the Pacific Ocean, the air gradually grows drier until January, when there is less than 1 grain of aqueous vapor to a cubic foot of air over the Dakotas, Wyoming, Kansas, Nebraska, and the greater part of Colorado ; while less than a grain and a half per cubic foot is then to be found over northwestern Texas, the greater part of New Mexico, northern Arizona, Utah, Nevada, Idaho,'and the western parts of Washington and Oregon. These conditions of extreme dryness in the sections just mentioned remain substantially unchanged during February, but by the end of March the nearly normal conditions of October again prevail. Indeed, the spring months of March and April and the autumn months of Sep- tember and October show for these regions about the normal conditions of the air as regards moisture, which conditions are, of course, always of greater dryness than in States of the same lati- tude east of the Mississippi River and along the west Gulf coast. During May and June the air is very dry over eastern California, New Mexico, Colorado, Arizona, Utah, and Nevada, over which regions a similar condition obtains during June, July, and August, except for southwestern Ari- zona, where the air becomes moderately moist. Exceedingly dry air during the summer and early autumn, with high mean temperatures of 70° and over, where there is less than 2 grains of water to each cubic foot of air, is found over southwestern Utah and eastern Nevada during June and Sep- tepaber, and over central Nevada during July and August. In general it occurs that the air is mod- erately moist over the Dakotas, Wyoming, western Nebraska, western Kansas, and Colorado from June to August, inclusive, except during unusual meteorological conditions, fortunately rare and local, which occur during periods of deficient summer rainfall and prolonged drought, when the air becomes exceedingly dry. During such periods of extremely dry air it occurs, although infrequently, that atmospheric disturbances draw this wry dry and highly heated air over extensive sections of coun- try lying between the drought-stricken regions and adjacent centers of atmospheric disturbance. No doubt exists in the mind of the Chief Signal OflScer that a general introduction of irrigation and the consequent growth of vegetation over regions to the southwest of Kansas would very 10 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. largely ameliorate the anfortunate meteorological conditions which at times result in the destruc- tion of crops in Kansas by extremely hot winds. The Chief Signal OflBcer has elsewhere pointed out that the very hot southerly and southwesterly winds experienced over Kansas and Missouri from September 12 to 15, 1882, were intimately connected with a drought, over southwestern Kansas and eastern Colorado, so prolonged that the surface of the country to the west and south of the wind- stricken districts was thoroughly parched and fiercely heated by the constant unclouded summer sun, whose action was facilitated by a continued absence of rain. It has also been pointed out that the frequency and intensity of similar visitations of very hot, dry winds have materially dimin- ished on the Pacific coast since 1859. For 7 years prior to that year, when the interior valleys of California wire substantially uncultivated, the number of hot days averaged 13 yearly ; from 1859 to 1871 the average yearly number was reduced to 4. The opinion was expressed and reiterated that the Immense quantity of land placed under irrigation in California, and the consequent vast increase in the area of vegetation, was an obvious reason why there should be a diminution in these destructive winds. As the regions from which the hot winds proceed have naturally a small rain- fall, any steps for the general protection of adjacent countries must be gradual, and also involve a great outlay of labor and money. Evaporation is a very important element in connection with irrigation. High temperatures and strong winds favor evaporation greatly, since at high temperatures not only will the air contain more aqueous vapor, but the water passes more quickly into the gaseous state, and the greater the quantity of air, whether " wet," " dry," or " very dry," which passes over the water surface, so much the greater the quantity of water lost by evaporation. If only 20 or 30 inches of water were lost annu- ally evaporation would be a factor of minor importance, but over the arid region the water which would be evaporated if freely exposed would attain a depth ranging from 5 to 9, and possibly in some cases 16 feet annually. Under these circumstances it is essential to consider these phenomena. The depth of water evaporated over free-water surfaces will be stated later, but it is advisable to call attention to Chart No. 4, which shows the variation in evaporation throughout the year. These curves are composite ones, made up from selected stations, and, therefore, fairly represent evaporation conditions over the States or sections to which they pertain. It is important to note that while evaporation is most rapid during the month of June in Arizona, Colorado, and New Mexico, yet in Utah and the interior valleys of California the greatest amount does not occur until the months of July and August. ,In Nevada the maximum evaporation takes place in August, while on the coast of California, curiously, it is delayed until the month of October. As a general rule the climatic conditions of the arid regions are marked by the presence of small amounts of aqueous vapor in the atmosphere, relatively high summer temperatures, and the prevalence of quite strong winds, which three conditions greatly facilitate evaporation. There are but few satisfactory observations of evaporation in the arid regions, and the crudity with which most of these observations have been made is such as to render many of them of doubtful value. Fortunately, investigations of this subject have been made by Prof. Thomas Russell, of the Signal Service, in which the final values, though obtained by somewhat empirical methods, are dependent in part upon careful observations of evaporometers made by skilled observers of the Signal Corps, and partly dependent, by theoretical connection, upon Signal Service meteorological observations of wind, temperature, and dew point for preceding years. The figures obtained and the curves drawn by Professor Russell show the amount of possible evaporation from free-water surfaces under favorable conditions, and it is believed that they can be depended upon as fair approximation to the existing physical conditions. In any event these are the only data extant which can be applied to the extensive region under discussion and so must be taken for what they are worth. It is deemed proper to again state that these figures and curves do not represent the actual evaporation over the whole surface of the State, but only the possibilities of evaporation. It should be further understood that the actual amount of water taken up by the atmosphere depends upon the opportunity of evaporation, which in turn depends upon the relative amount of water surface the wetness or dryness of the soil and its constituents, and upon the amount and character of vegetation covering the region under consideration. It may be questioned by those who have not considered this subject in view of the observed facts, that these possible evaporations are far iu excess of the actual amounts which could be IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. ' 11 absorbed from a water area, say, of 100 square miles, but such would be an erroneous supposition as indicated by facts observed on an enormous scale. The most convincing and striking case is that of the Caspian Sea, with an area of about 180,000 square miles. As this is a closed sea of very large area, it is in fact the largest evaporometer in the world, where the silent but powerful operation of nature's forces in this direction are susceptible of direct observation and measurement. It appears from Woeikof (Climates of the Earth, p. 226) that the actual annual evaporation frooi the Caspian Sea is equal to 1.09 metres, or 43 inches of water. These figures have been determined from observed heights of the water surface of the Caspian Sea, in connection with the measured inflow of the Volga and other contributing rivers. The great contrast between evaporation over extended water surfaces within the limits of the United States is illustrated by Professor Gilbert in his valuable and exhaustive monograph on Lake Bonneville, which came to hatid just as this report was finished. Professor Gilbert gives the amount of evaporation over the surface of Lake Michigan as equal to a layer of water 22 inches deep, this result being derived from the report of Mr. D. Farrand Henry on the meteorology of the Laurentian lakes and the report of the Chief of Engiiteers for the year 1868, Washington, 1869, p. 980. Professor Gilbert estimates that 80 inches of water are yearly removed from the Great Salt Lake, an estimate closely agreeing with the evaporation values determined by Prof. Thomas Russell, Signal Service, for this region, since according to his calculation the evaporation at Salt Lake City, near the southeastern shore of Great Salt Lake, amounts annually to 74.4 inches in depth. Professor Gilbert speaks of this locality as follows: * * * As in other desert regions, precipitation here results only from cyclonic disturbance, either broad or local, is extremely irregular, and is ofteu violent. Sooner or later the "cloud-burst" visits every tract, and when it comes the local drainage-way discharges in a few hours more water thau is yielded to it by the ordinary precipitation of many years. The delage scours out a channel which is far too deep and broad for ordinary needs and which cen- turies may not suffice to efface. The abundance of these trenches, in various stages of obliteration, but all mauifestly unsuited to the everyday conditions of the country, has nathrally led many to believe that an age of excessive rain- fall has but just ceased — an opinion not rarely advanced by travelers in other arid regions. So far as may be judged from the size of the channels draining small catchment basins, the rare, brief, paroxysuiul precipitation of the desert is at least equal while it lasts to the rainfall of the fertile plain. » » » Experiments in Sydney, New South Wales, under the direction of Mr. H. C. Kussi'Il, govern- ment astronomer, shows that the amount of evaporation from day to day depends very materially upon the conditions of the soil. If it is wet on the surface evaporation proceeds much faster than . over water, but as the ground dries the earth evaporates less than the water, and, what is a very im- portant matter when considered with reference to large areas of the arid region of the United States, when the soil becomes dry and is packed hard, surface evaporation substaiitially ceases, even when the soil is damp enough below to keep vegetation growing. These experiments in New South Wales show the very important factor which suitable vegeta- tion will exercise in bringing subsoil water to the surface, and thus increasing evaporation during the dry portions of the year. The results of the experiments show that evaporation from grass soil is more regular than from bare soil, and in the course of the year it lost more than dry earth by 14 per cent, and also evaporated 9 per cent, greater than water surfaces. Reeve's experiments at the London Water Works show evaporation from grass land to be 12 per cent, less than from water. In Sydney, during a year of deficient wind, in 1885, the water evaporated most, but in a wet and windy year the grass evaporated most. It must be admitted, however, that careful and extended observations will be necessary before the definite relations of different classes of vegetation to evaporation have been determined with that accuracy which the importance of this question to the farmer demands. In 1888 special observations upon evaporation were made at Lake George, New South Wales a body of water with about 80 square miles of surface, at an altitude of 2,200 feet and surrounded by high land; the lake itself is shallow, espec ally at the margin. During 1888 the evaporation amounted to 47.72 inches, which in round numbers was twice the amount of the whole rainfall. In 1889 a valuable set of observations were made by means of a tank at Lake George, while the evaporation of the lake was also determined from day to day. In 1889 the evaporation of the lake was 44.29 Jnches, which gives an average of 46 inches for the 2 years. 12 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. Evaporation observations made from a pan in comparison witli those from the Pich6 evaporom- eter at Sweetwater Dam, San Diego County, Oal., show that the Pich6 evaporometer indicates, if anything, less than the true value of evaporation from free water surfaces. This deficiency amounts to about 8 per cent., the Pich^ evaporometer indicating for the 7 months of the year 29.88 inches, the pan observations 32.33 inches. In 1889 observations made from water in pans at Albuquerque, N. Mex., under the snpervision of the TJ. S. Geological Survey, showed evaporations as follows, in inches: June, 9.6; July, 9.6; August, 9.3; September, 7.5; October, 4.1; a total in 5 months of 40.1 inches, which would proba- bly amount for the whole year to about 80 inches, the evaporation as calculated' by Professor Russell. The average amount of water which could possibly evaporate yearly, expressed as depth of water in inches, and also in cubic miles of water, is as follows : States. Total amount. Average depth of possible evaporation. States. Total amount. Average depth of possible evaporation. Cnhie miles. 170. 9 90.9 108. 6 Inches. ■ 67 68 69 CiMc miles. 146.2 145.9 U^. S Inches. 78 Utah 80 90 As is stated above, a layer of water to the depth of 67 inches could evaporate from the entire surface of California during a year of normal temperature, -wind, moisture, and sunshine, l)ut the difference in the amounts which could evaporate over different parts of the State are very great, increasing very rapidly inland, being about 37 inches along the immediate coast ^^nd rising to about 50 inches in the extreme northwestern part, 84 inches in the northern part, and over 100 inches in the southern part. In the very extreme northeastern part — in the Fort Bid well region — evapora- tion, however, barely reaches 50 inches. Over fully one-third of California — the extreme eastern, and particularly the southeastern portions — the possible evaporation could reach, if free water surfaces continued throughout the year, the depth of 7 feet or more. Over Utah the climatic conditions affecting evaporation are extremely constant in their com- bined operation, and probably of nine- tenths of the entire area the possible annual evaporation would neither exceed 75 inches nor be less than 70 inches. Over Colorado the resulting conditions are likewise constant for the State as a whole, the possible evaporation ranging between 65 and 70 inches. The conditions for evaporation in New Mexico are also very constant in action, and are quite accurately represented by the data from three stations, differing widely in geographical position, elevation, etc. — Fort Stanton with a possible value of 76 inches, Santa F6, 80 inches, and El Paso, Tex. (separated from southern New Mexico only by the Rio Grande River), 80 inches. In Arizona the climatic conditions are such as to produce widely varying results, the differ- ence between the extremes being well represented by the annual possible evaporation of 55 to 65 inches at Prescott and Fort Apache, respectively, in the highlands of the Territory. Over the belt of country extending from Fort Grant west and northwest to the Colorado Eiver, and embracing a large portion of the Gila River above the junction of the Salt, also over the Maricopa and Tuma Desert and the lower portion of the valley of the Colorado-Grande, the possible evap- oration rises to or exceeds 100 inches yearly. Nevada, as a whole, is a State over which the phenomena of evaporation obtain to the greatest extent. There is but little, if any, part of Nevada where the possible evaporation does not exceed 80 inches annually, and this increases gradually from the northeastern to the southwestern corner attaining, over the whole southeastern part of the State, a depth of more than 90 inches, and in some localities over 100 inches, annually. The extreme dryness of the air would doubtless be relieved by irrigation, and this increase of the absolute humidity in the atmosphere would be considerable, locally in cases where light winds occur or calms prevail, while in cases where steady winds occur the benefit of the increased humidity would naturally be enjoyed by the country to the leeward of the irrigated section. IRRIGATION AND WATER STORAGE IN THE ARID REGIONS, 13 The relation of the actual amount of aqueous vapor in the air to the average temperature is an important one, and such relation is shown by the composite curves of temperature and aqueous vapor for each State on charts Nos. 2 and 3. As might be expected,, the actual quantity of Water in the air increases, as a rule, with increasing temperature, so that the amount present is from two to three times as much during the summer as during the winter months. A careful examination shows, however, that the increase in the quantity of aqueous vapor is not commensurate with the increase in temi)erature from the coldest to the warmest month, so that, although there is much more water in the air during the summer months than during the winter, yet the dryness of the summer months is very much greater, owing to the average- humidity. It would naturally be expected that the greatest amount of water would occur during the month of the highest temperature, but this is not so ; for while this is true in some States and localities it is not true in others. For instance, in Nevada, as a rule, the warmest month is July, while the largest aimouut of water in the air occurs during August, thus making the humidity conditions of August considerably more favorable than those of tj^uly. Along the Pacific coast the largest amount of aqueous vapor obtains during August, while the warmest month is that of September. In the interior of California, however, different conditions obtain, the maximum amount of aqueous vapor occurring in July while the highest temperature is during August; that is to say, reverse conditions obtain in the interior valleys of California during July and August to those' in the adjacent State of Nevada. In Arizona, Colo- rado, and New Mexico the greatest amount of aqueous vapor coincides with the highest monthly temperature, and the disparity between the humidity conditions of winter and summer is less marked and trying to vegetation than in California, Nevada, and Utah. The frequency and average daily amount of precipitation are very importan t climatic character istics bearing directly on this question of irrigation. In certain localities the rainfalls are frequent and come in moderate showers; in other places infrequent, with moderate daily rainfalls, while in other places very dissimilar conditions to these obtain, of infrequent rain occurring in heavy showers or very infrequent rainfalls in small amounts. For instance, the average amount of precipitation on each rainy day is 0.25 inch of water at Milwaukee, with 134 rainy days in the year; at Rochester, 0.19 inch daily average, with 171 rainy days ; at Pensacola, 0.19 inch, with 124 days in the year; at Poplar River, Montana, 0.12 inch, with 83 days. The question as to how rain comes — whether slowly and steadily in quiet showers or violently in large amounts — is not only important from the general standpoint of irrigation, but also from the practical question of storage by reservoirs. In Arizona, for instance, from 30 to 40 per cent, of the entire precipitation occurs in heavy showers, where the rainfall is upwards of 0.75 inch during a day, of precipitation, and frequently more than an inch falls in a single shower. At Fort Grant 31 per cent, of the rainfall occurs in heavy showers ; at Fort Apache, 29 per cent. ; at Tort Thomas, 30 per cent. ; at Fof t Verde, 38 per cent. ; at Prescott, 41 per cent. In New Mexico, at Fort Wingate, 30 per cent, of the rainfall occurs in heavy showers, and at Fort Stanton 24 per cent., while at Santa F6 only 18 per cent, thus occurs. At Salt Lake City 19 per cent, of the pre- cipitation is in heavy rainfalls, while at Winnemucca, Nev., only 5 per cent, thus occurs. . It is also most important to consider at what season of the year the very heavy rainfalls come, and as to whether the water is in such quantities as to render it possible to reserve it by storage for use during the drier portions of tlie year. It is evident, for instance, that the value of waste water stored for irrigation depends very largely upon the season of the year in which it is caught, since in the arid regions, where :evaporation is so extremely rapid and constant, water which is caught and stored immediately after the ripening and harvesting of the important crops must be held for many months, subject to enormous loss in variqus ways, while, on the other hand, rainfall caught just before or at the beginning of the agricultural year will furnish to the irrigated land a much larger percentage^sf the water originally stored. Again, is the storage water to be gathered from gradual rains or from violent thunderstorms and cloud-bursts? In this latter connection extracts from the Monthly Weather Reviews of the Signal Service show what may be expected in the way of violent floods, and the possible damage resulting therefrom. These data may be said to cover only the past eleven years, as the data prior to the year 1879 have never been properly colla,ted or examined. 14 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS.

A short distance from Palmetto these clouds seemed to join and rushed with extraordinary swiftness toward the town. The resultant cloud was riven with lightning, and the air became filled with a terrific roar above which the thunder was hardly audible. A column of water poured down, excavating a trench about 500 feet long, and, in places, 7 feet deep and 20 feet in width. Within 10 minutes tlie entire lower part of the Palmetto Valley was 2 to 3 inches under water, and the caBon leading to Fish Lake Valley was a torrent. The stage road was obliterated for 9 miles, although the rainfall extended but little beyond Palmetto. The storm of the 7th at the same place was very similar to that of the 11th, except that the rain seemed to come from one cload only. This cloud appeared to touch the ground and roll down the mountain side, and the rain covered a greater area. NEW MEXICO.

JuTg, 1883.— During the afternoon of the 29th a destructive flood occurred in the Kacab Canon, in the soathern part of the Territory. All of the wheat in the upper settlements was washed away, and a number of cattle were drowned. Many wagons and agricultural implements were lost. March, 1^84. — At North Fork the Central Pacific trains were delayed for two days previous to the 7th, owing to an overflow of the Humboldt River. T;ie water in Bear River was higher than has been known since 1873. The river rose 7 feet in 24 honrs, washing out all the bridges. Two bridges on the Waldo River were also washed away. May, 1884. — The rivers throughout the Territory were much swollen during the month and the lowlands in the southern part of Salt Lake City were flooded. At Ogdeu several dams were swept away. Numerous washouts occurred on the Union Pacific. The Denver and Rio Graude Railroad was flooded, stopping all trains. The water in Great Salt Lake reached a greater height than has been known for many years. At Nephi, in Juab County, the rail- road bridge over the forks of Salt Creek was washed away on the 9th. June, 1884.— The lowlands of Salt Lake City continued flooded during the month. Dispatch of trains was impracticable on the Denver and Rio Grande Railway for 3 weeks. August, 1885.— A cloud-burst occurred on a ridge of mountains about 3i miles northwest of Frisco at 9 p. m., on the 22d. The water is reported to have rushed down the sides of the mountain with such force that large bowlders were displaced. July, 1887. — On the evening of the lOth a flood devastated Fillmore and the surrounding country. The greatest damage was done in the mountains east of the place. Three saw-mills and half a herd of sheep were swept away. August, 1889. — The rainfall was reported unusually heavy at Salt Lake City and surrounding districts, causing washouts on the Union Pacific and Utah Central Railroads. A laud-slide, caused by a cloud-burst, wrecked a freight train at Weber Canon. From the foregoing list it appears that the excessive and damaging rainfalls, according to their order of greatest frequency, occnr in the respective States and Territories as follows : Cali- fornia (southern part), Colorado, Arizona, 'Sew Mexico, Utah, and Nevada. H. Ex. 287 2 18 IRRIGATION AJTD WATER STORAGE IIS THE AKID REGIONS. These destructive rainfalls in Colorado occurred without exception during the summer season, the 17 cases on record being distributed as follows: July,6; Angust,5; May,4; Jane,2. InNevada the excessive rains have been confined, with one exception, to the summer months, the records being, August, 3; June, 2; December, 1. Utah is marked by a similar inclination,, the 8 cases being distributed as follows: August, 3; July, 2; June, 1; May, 1; while March is the only cold month marked by a heavy rainfall. In New Mexico, of the 12 cases none occurred during a winter mouth; the distribution was as follows: August, 5; September, 2; June, 2; July, 1; April, 1; October, 1. California, on the contrary, has only 1 case of damaging rainfall during the summer months, that of August, li?8 ), near Daggett, in the Yuma desert ; the 19 other cases were distrib- uted as follows: January, 5; December, 3 ; February, 3;» October, 3; March, 2; April, 2; No- vember, I; the tendency being entirely towards heavy rains during the rainy period. The south- ern part of California only has been here considered, and these cases are connected with the unusual extension of rain conditions to the southern half of the State. Arizona, while sharing the tendency to summer rainfalls to a great extent in common with Colorado, Nevada, Utah, and New Mexico, yet has occasional cases of severe winter rainfalls. Fifteen instances are divided as follows: August, 5; September, 2; October, 2; Jnlj% 1; making 10 cases in the late summer and early autumn, against 3 in December and 1 each in Febrnarjt and March. It appears, then, from the records that the excessive rainfalls from which, as has been shown elsewhere, is derived about one-third of the whole rainfall of the arid region, occur very largely during the months of July and August, at a period too late, as a rule, for the economical utiliza- tion of such rain as storage of water for the staple crops of that season. Occurring, as these heavy rains do, during the late summer or very early autumn, the water can be utilized on a very large scale only for such crops and productions as can be planted, cultivated, and grown during the autumn and winter season; since, as is shown by data already quoted, of the water stored and held over until the following spring, an enormously disproportionate amount of it must have passed into the air by the steady and inevitable process of evaporation. More than special interest attaches to the variation in the amount of rainfall from year to year. For instance, in Colorado the greatest amount of rainfall in any year ranges, as a rule and according to locality, from 110 to 150 per cent, of the average annual amount, and the minimum yearly rainfall varies from about 30 to 80 per cent, of the normal. In Utah the maximum yearly rainfall, generally, varies from 130 to 180 per cent, of the normal, while the minimum ranges from 35 to 70 per cent. In New Mexico the maximum generally amounts to from 125 to 150 per cent., though occasionally, at such widely-scattered stations as Forts Union and Craig, and Albuquerque, doublethe amount of yearly rainfall has been known. The minimum in this Territory varies from 40 to 80 per cent, of the average. In Arizona the maximum amounts for any year are generally between 130 and 200 per cent., the greatest departures from the annual average being at Fort Mojave, 240, and Fort Verde, 250 per cent, of the usual atnount. The minimum rainfall averages generally from 45 to 75 per cent, but in one notable instance, Maricopa (record of 10 years), the amount in 18'i2 was only 8 per cent. In Nevada the maximum generally averages from 130 to 190 per cent., but at Fort McDermit the maximum rainfall is 330 per cent, of the yearly normal. The minimum for the State ranges from 40 to 60 per cent., according' to locality. In California the maximum varies from 150 to 200 per cent., and in occasional localities in the southern part of the State ranges from 240 to 300 per cent. The minimum yearly amounts vary from 25 to 60 per cent., but at one place i n the Mojave desert, at Indio (record of 14 years), in 1886 only 6 per cent, of the normal rainfall occurred. In short, the amount of rainfall which may occur over the arid regions in different years varies enormously. In Colorado, New Mexico, and Utah, the amounts in the years of greatest rainfall may be from two and one-half to three and one-half times as great as in the years of the least rainfall; in Arizona, from three to four times as great; in Nevada from three to five times as great, and in California from four to six times as great, with even greater variations in particular localities. • The late damaging floods of February, 1891, only empliasize the tendency of destructive rains to occur almost entirely in California daring the winter season. t The very violent and damaging rains in soutbciistem Arizona in February of this year occurred only in that part of Arizona which has a rainfall regime in substantial accord with that of southern California, IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 19 The most important informatioo pertinent to the qaestion of irrigation is the annnal rainfall for the regions affected.

When perfected, the storage reservoirs must be sufficiently extensive to tide over the temporary droughts, and sufiBciently provided with waste-weirs to safely discharge extensive and torrential rainfalls; and must be protected by cover or otherwise against extensive evaporation, while the fall of the feeding canals must be such, and the water conducted therein must be sufflcieut in quantity, as to insure the speedy delivery of the water without great loss by leakage or evaporation. Further examination of the detailed data will show that while for very large areas the amount of rainfall and its distribution is such as to insure a copious and quite constant precipitation available for purposes of irrigation, yet within 100 or 200 miles of this same area may be others where the rainfall is so irregular in its fall and distribution, and so deficient in its quantitiy, sis to render most doubtful the economic success of irrigation enterprises. Likewise, contiguous to other climatic conditions favorable to irrigation, may be found rapid evaporation, the continued pres- ence of very dry air, and also of quite high summer winds, all unfavorable to irrigation enterprises. Not only has the average depth of rainfall in inches been calculated for each State, as a sup- 2)lement to the charts herewith attached, but a similar calculation has been made as to the aver- age depth of rainfall between different altitudes. While these results have a scientific interest 20 IREIGATION AND WATER STORAGE IN THE ARID REGIONS. in showing clearly the increase of rainfall as a whole with elevation, yet they have a practical result in indicating to the investor the average gross amounts of water (that is, without loss by seepage, evaporation, or otherwise) in each State from which the irrigating supplies must be drawn. It is evident, for instance, that no more water can be available for land above 5,000 feet in Arizona, California, or elsewhere than actually falls above that level. The amount of rainfall in cubic miles has been calculated for each State, and also between certain altitudes, the excellent map of the Geological Survey having been used lor obtaining data" whereby to calculate surface areas between different altitudes in the States named. From these combined data we learn, for instance, that in Utah 13.7 cubic miles of rainfall occur in average years; in Nevada, 18.6; in Colorado, 20; in Arizona,. 22.3 ; in New Mexico, 25.2, and in California 56.3 cubic miles. It is not to be supposed, however, that this quantity of water, or even an approximate amount thereof, is available for irrigation in any particular year. A very large amount of water is lost through absorption by the earth, and a very large amount passes into the air by evaporation. Further, as has been pointed out elsewhere, the quantity of rainfall varies largely in different years, so that in Utah, for instance, the rainfall in one year may amount in the gross, to 6 or 7 cubic miles, while in another year it may reach 20 cubic miles. The amounts given,- however, have an important practical bearing which will be readily comprehended by those having irrigation enterprises under consideration or in course of Qonstructiou. The elements of cloudiness and of sunshine bear both directly and indirectly on irrigation problems, the presence of sunshine being necessary in certain months. of the year for the fruition of growing crops, and the presence of cloudiness also being essential, as during its presence evap- oration proceeds in a much more modified degree. Chart No. 5 shows the sunshine and cloudi- ness — the percentage of sunshine being shown directly and the cloudiness being, of course, the complement of the percentage of sunshine. These curves are composite, being -derived from observations of cloudiness at selected stations in the States and Territories referred to. It has been assumed — a reasonable assumption, in which no large error can obtain — that the comple- ment of the cloudiness will be the sunshine. It might naturally be assumed that the curve showing for each month the precipitation would, as rainfall is associated with cloudiness, follow in diametrically opposing phases the curve of pre- vailing sunshine. How far this is true it may be well to determine. Taking the Paciflc-coast region as a rule, the amount of sunshine bears a very close and direct relation to the absence of rainfall, the dryest months being those of July and August, and during the latter of these two months the maximum amount of possible sunshine occurs, except in lower interior California, where the greatest amount of sunshine comes — fortunately for the raisin districts — in September, which is even less marked by the presence of clouds than the very sunshiny months of July and August. In Arizona and New Mexico, however, where the percent- age of precipitation is considerably larger in August than in any other month, it appears that the largest amount of unclouded sky obtains, not in that month, but in the month of July. How- ever, the extremely sunshiny months of June and October are marked in New Mexico and eastern Arizona by a pormal amount of monthly rainfall, the precipitation occurring in short, sharp showers. In Nevada the smallest percentage of rainfall occurs during July, during which period the amount of sunshine is somewhat less than for August or September. Cloudiness is an important element, since the presence of clouds naturally results in screening the earth from excessive action of insolation, or, in other words, in diminishing the heat received by vegetation from the direct rays of the sun. It also, acting as a screen, prevents in part thd radiation of heat from the earth into space, and thus materially tends to modify and r.educe the diurnal range of temperature, so that growing vegetation is not subject to as great cold as would otherwise obtain during the night, nor, oii the other hand, does it receive the full amount of solar heat by day. While the amount absorbed by a fully clouded sky is not accurately known, yet it must be so considerable as to form an important element in agriculture. On the other hand, the absence of clouds facilitates greatly the process of Insolation by day and radiation by night, thus increasing the range of temperature to which vegetation must adjust itself daily. While the highest amount of insolation or the full heat of the direct rays of the sun— the amount for each lEEIGATlON AND WATER STORAGE IN THE ARID REGIONS. 21 locality necessarily depending on the elevation, latitude, and mean temperature of the growing season for that locality — ^is absolutely essential to the complete fruition of many crops, yet the max- imum amount of possible insolation in the arid region, when occurring during the summer period over very extensive areas of that region, proves destructive to most vegetation which is not watered by irrigating methods. Representing the total cloudiness by 100 per cent, and absolutely clear sky by 0, it may be considered that those regions are practically cloudless over which the average amount of cloud is 20 per cent, or less, and that an excess of cloudiness obtains when the face of the sky is covered on the average SO per cent, or more. On this basis ic appears, as might be expected from what has been stated before regarding the distribution of rain throughout the year, that the different sections of the arid region had not an ideuticalcloud regime, in other words, that the excess of cloudiness and the periods of complete sunshine do not occur over the whole arid region during the same months. An examination of the entire region west of the one hundredth meridian shows that cloudless days (an average of 20 per cent, or less) do not obtain over any part of this region during January, February, or March. In December the areas of cloudless regions are very limited, including only portions of extreme southeastern California and southwestern Arizona. In April this area comprises within its limits the southern half of Arizona, the extreme south- eastern part of California, and southwestern New Mexico. During May and .Tune the cloudless area of April is extended gradually to the north and southwest, so that in the latter month (June) the sky is practically cloudless over western New Mexico, Arizona, southwestern Utah, southwestern Nevada, and all of California except the extreme northern part and the immediate coast region of the latter State, say 20 miles inland. During July, Utah, New Mexico, and Arizona, except a limited portion of the lower valley of the Colorado in the last-named Territory, are entirely removed from the cloudless belt, which now obtains over California, except the immediate coast region and western half of Nevada and southeastern Oregon. During August this area is not changed, except that it includes the greater part of Idaho, all of northern Nevada, and extreme northwestern Utah. It may be stated that during July, August, and September, the period of nearly constant sunshine reaches its maximum over the interior valleys of California, during which time very large areas of clouds are comparatively rare. In September the cloudless region includes California, except the imihediate coast, south- western Oregon and Nevada, as in the preceding months, and also extends southeastward so as to include southern Utah and all of Arizona, except the southeastern portion. In October the only changes are the gradual movement southward and inland from the sea of the limiting lines in California and Nevada. In November the area is diminished so that cloudless weather occurs only over southeastern California and the southwestern half of Arizona; which region is still further reduced during December and disappears, as before stated, in January. Of course the climatic conditions of Colorado, Utah, northern Nevada, and the northern parts of Arizona and New Mexico iare such as to preclude extensive and successful cultivation of crops during the autumn and winter months. The southern half of California and also the southern part of Arizona have, however, such conditions of temperature during the autumn and winter as are favorable to the planting and growth of crops during these seasons of the year ; and fortu- nately, also, the heavy rains ot California occur during the late autumn and early winter, which favorable condition extends to a much slighter degree over the southern part of Arizona. It is not part of the province of the Weather Bureau to dwell upon the question of storage of water by reservoir, but it is believed that it is expected that the Chief Signal OlBcer should set forth clearly such physical factors of the question as pertain to meteorology and climatology. What has already been said shows, however, that over very extensive sections of the arid regions the heavy rains from which must' be derived waste water for irrigating purposes come at such a period of the year as to render it necessary to keep the water stored for a long time before it can be gen- erally used for iirigating purposes ; that such storage occurs in countries and under conditions where evaporation proceeds rapidly and to a degree almost unequaled in any other part of the world ; and also, that the violent rainfalls are in such quantities and cover such an area of country 22 IRRIGATION AJSTD WATER STORAGE IN THE ARID REGIONS. that the whole of these waters can not be stored; and that where storage facilities are provided they must be of most durable and solid construction, with such facilities for carrying off waste water as will render the recurrence of calamities similar to the great disaster on the Hassayampa River in Arizona practically impossible. The Chief Signal Officer attaches to this report tables of precipitation and temperature which have been prepared under his personal direction, with reference to Arizona, California, New Mex- ico, Nevada, and Utah ; together with certain charts intimately connected therewith. He further appends memoirs upon the climatic conditions with reference to irrigation, for Arizona, California, Nevada, and New Mexico, prepared by First Lieut. William A. Glassford, Signal Corps ; which will further supplement the more general report of the Chief Signal Officer, and will further illus- trate the tables and charts attached to the main report. ' The effect of the wind in connection with evaporation has elsewhere been referred to. The velocity of the wind is also a factor not to be neglected in treating this question of storage of water for irrigating purposes. It furnishes an economical and effective motive power which has to some extent been utilized in the arid regions, but which in the coming years must prove to be a valu- able agent in storing water, whether used in raising it, as possible, from the Missouri River to irrigate the plains of the Dakotas or in raising artesian water which has not sufficient head to bring it to the surface of the earth at the desired point. The average daily and hourly wind move- ment is given for five stations in Arizona in Appendix No. 10. The data for Phoenix are given as being the locality where the wind is perhaps the feeblest of any point in the arid regions. As a general rule it may be said that the average hourly veloqity for the arid region diminishes from a maximum of 7 to 10 miles in the spring months to a minimum of 5 to 7 miles in the late summer and tall months.

Signal Office, War Department, Washington City, December A, 1890. Sir : Acting ander yonr orders, which included a copy of the resolution of the House of Bepresentatives, I have prepared a report upon the climate of Arizona. The text of this I have the honor to submit to you, together with tables of rainfall and temperature, and charts, as noted below. When published as an individual monograph, after the course yon followed in publishing the report on the climate of Nebraska, it will be possible to distribute to the citizens of Arizona only such matter as immediately concerns them, and there will thus be effected a most considerable saving of the puWic funds. Your own review of the broad principles and general features of the region at large will be an indispensable introduction to the more particular and local examination, which alone has been within my power. Concerning the report, the tables, and the charts, a few words may be said. The tables present the records of rainfall and temperature noted at the several stations which have been maintained in Arizona for less or greater periods. In some cases, where otherwise valuable records were briefly Interrupted, their continuity has been main- tained by interpolation of mean values, a justifiable ap'proximation, without whicjh climatic examinatioii of many districts would have proved impossible. Such interpolations are clearly indicated by braclcets. The maps have been provided with systematic contours of altitude derived from the unpublished data of the U. S. Geological Survey, which information was put at the disposal of the Signal Service through the kind personal interest of Mr. Henry Gannett, of that survey. In the text of the report, attention has been particularly directed upon such climatic factors as seemed pertinent to the scope of the inquiry which was especially authorized, as a contribution to the study of irrigation within the Territory, on such data as properly are included in the province of the Signal Service. Other climatic features have been considered solely as collateral to this main topic, and have received attention at greater or Jess extent according to their influence upon the rainfall. There have thus been introduced incidental investigations of temperature, winds and evaporation. In general, it is to be said that the memoir is primarily designed to present to the last degree of accuracy climatic facts of record up to date, in order that not only may the irrigation problem be studied with a full acquaintance with the facts of nature concerned in such study, but that the data here presented may serve as a basis for future study of the Arizona climate, and possibly* interest yet other citizens of that growing Terrlto^. to provide still more material by undertaking voluntary observations. Secondarily, an effort has been made to harmonize all this mass of material into a consistent review of the climate, with particular presentation of certain preponder- ating influences. It is believed that no staitement has. been made which is not amply justified by the existing data, yet it is possible that, at some later period, the mass of data may become so much more representative of the entire Territory that the present memoir will be brought under rigid review. In that case it is confidently expected that while some statements may be found to need modification, the general tone of the results herein attained will receive confirmation. The discussion of the scientific meteorology of the region has been reserved for the memoir of like nature which deals with California. In that an attempt has been made to explain the causes of the peculiar seasons of the Pacific States and Territories, and to show their intimate correlation with the climatic laws which rule the whole United States. Very respectfully, W. A. Glassford, Second Lieutenant Signal Corps, Signal Officer and Assistant. Chief Signal Officer. 301 302 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. ARIZONA. INTKODnCTION. Any inquiry into the reclamation of lands at present arid in Arizona would be essentially incomplete which con- fined its scope to the mere noting of the position, area, and character of the soil capable of such reclainatioB, of the amount of water which may be drawn from the existing sources of supply, and of the engineering problems presented in the construction and maintenance of dams and other appliances for collecting and storing the waters, and of aqueducts, flumes, and other conduits to bring the water upon the soil which so greatly needs it. These are indeed of prime importance. It is necessary to comprehend clearly these factors,'the reclaimable area, the hydraulic potential of the rivers and other streams, and the ease or difficulty, as a problem of pure engineering, of applying the hydraulic potential to the reclaimable area and transforming its aridity into fruitful iields. Yet, important as are these factors of the inquiry, they are not ultimate. They belong naturally in the province of the geographer and the engineer. They are results; their determining causes must be closely studied before it becomes possible to appreciate their full bearing, and it is this study of original causes which may be expected from the Signal Service. The rich alluvial bottom lands of the valleys of the Gila, the Hassayampa, the Colorado, the Eio Verde, the Salt River, are the objects of the attention of the investor and the settler who can claim and command the services of engineering science. The causes are to be sought by th6 meteorological student, who will find them in the physical geography of the district and its hyetophysics. The origin of every grain of humus in the basins of the lower rivers is to be foand on the jagged mountain peaks, on the bare plateaus, and in the eroded canons of the central and northern portions of the Territory; the origin of every drop of water that flows to waste upon the shoals of the Gulf of California, of every inch of water that by wise forethought has been applied to the moistening of a soil, so rich as to need no 'reinforcement of artificial fertilizers, must be sought in the winter and summer rains, in the lingering mountain cap of snow, and in the destructive suddenness of the so-called cloudburst. These are the elements of the problem, which must be presented briefly and succinctly in order that it shall be clearly appreciated from the outset, that : (1) The causes which have produced the alluvial bottom lands are of continual and present operation, and are to be counted on to restore all waste, whether it be the molecular loss of soil washed away as detritus or the chemical waste of soil depauperated by the growth of crops. (2) That these causes must be accepted as constant factors, not to be altered or avoided, but whose action may be diverted to channels which shall aid rather than retard the enterprise of human industry. It is, then, a necessary preliminary to the study of the arid land and its availability for reclamation, that a presentment be made of the essential features of the district (Which it happens is very nearly coterminous with the Territory), of the phenomena of aqueous precipitation and of climatological data incidental thereto, which may le' properly comprehended under the general designation of hyetophysics ; and, finally, of the manner in which thete mutually interacting forces combine to produce the resultant known as the arid land of Arizona. PHYSICAL GBOGRAPHY. It is well within limits to remark that this Territory presents the problem of rain catchment and water storage and economical distribution, together with notable reclaimability of the land to be irrigated, in terms of almost ideal simplicity. Not a single component of the problem needs determination ; every one is evident, and the answer is but the accurate sum of known quantities. This is true despite the great area of the territory. The principle which holds good on every farm where vcater is drawn a few yards from spring or pool is here equally plain, although every factor is magnified a thousand fold; for yards read miles, and instead of a single farm consider an area as great as that of Italy, double the measurement of the six New England States combined. Italy numbers its drainage basins by the score. New England by the dozen, Arizona but by a single pair. If extreme simplicity marks the river systems the mountain system is no more complex. It is this uniformity of the lasting determinants of the character of the land which has made the study of the irrigation potentialities of Arizona at once so plain and so interesting, and which has brought it to pass that this study must take rank as an almost absolutely necessary primer to the study of lauds where the same factoi'S are presented in far more complex combinations, and where occur many complications which must be eliminated. This simplicity plainly appears from the summary topical arrangement which it is possible to make of the physical data of the district under consideration. Orography.— The axis of the mountain system of Arizona is remarkably well defined and appears with the utmost distinctness, not only in the general trend of the main mass of elevation, but also in minor ranges and notably in detached spurs often widely separated froni the plateau system to Which, on the score of altitude, they may claim to belong. "With sufficient accuracy to satisfy all legitimate demands of the present inquiry, the direction of the moun- tain axis may be placed at northwest and southeast. That this is true in the main system will at once appear from a glance at any map; its corroborative repetition In the detached spurs is sufficiently noteworthy to call for a moment's consideration. Thus upon the bench or mesa of less than 3,000 feet of altitude there appear two interesting groups of long and narrow mounts which exhibit most unmistakably the characteristic axes. One group *which flanks on the west the valley of the Rio Santa Cruz, in Pima County, contains fifteen members rising to an altitude of more than 3,000 feet from a mesa 2,000 feet high; of this number six reproduce the distinctive trend of the system six more vary from it but slightly, and no more than three present a divergence as great as 60°. A still more characteristic butte system on the same horizon is found in the Gila Valley, just north of latitude 33° in Maricopa County, lEEIGATION AND WATER' STORAGE IN THE ARID REGIONS. 303 Of the twelve membera of this system, four rise from a mesa of 8,000 feet of altitude to a height of more than 3,000 feet, the remainder rise from a bench 1,000 feet lower to a height of 2,000 feet, and two of these latter to more _than 3,000 feet; not one member of t^e system diverges from the characteristic axial direction. The table-land of 3,000 feet is crowded with sierras of 5,000 feet and upward, whosg direction indicates beyond a chance of doubt the prevalent mountain-making forces which have here been at work. Even Jhe lofty plateau of 5,000 feet shows in two systems six examples Qf considerable mountain masses of from 7,000 to 9,000 feet, rising at one point to more than 13,000 feet; the systems themselves and their individual members show this same axial inflection. Nor is this confined to surfaces of elevation only, many of the rivers which flow in canons of erosion take the same bearing; for instance, the northwesterly flow of the Colorado Chiquito, in Yavapai and Apache counties, of the San Pedro In the counties of Cochise and Pinal, of the Gila in Graham County, and the Santa Cruz in Pinal, while the southeasterly flow of the Rio Verde and many of the confluents of the Salt River in the mid. 1,000 Total : 566,460 On a matter of such interesting moment particulars are not out of place, and it is on this account that these figures are examined with some detail. 310 IREIGATIOH AND WATER STORAGE IK THE ARID REGIONS. Pima County. — This border ooanty is one of the least explored in Arizona and, with the exception of scattered mines in the Quijotoa moantain district, settlement is restricted to a narrow north and sonth strip between the extreme eastern boundary and the Eio Santa Cruz. Yet notwiths tanding the narrowness of this settled strip there are 7,500 acres under irrigation. In the i mmediate neighborhoodof Tucson are thirty-six ditches which irrigate fully 3,000 acres iu their 56 miles of extent. Some of these ditches have been in use since 1690 and three of the reservoirs date from the same year, namely El Cunloso, Missional, and Del Eey. Several ditches are now constructing, of which two are of considerable magnitude, one at Santa Cruz and the other near Tucson. The extension of the irrigation system contemplates the addition of fully 2,000,000 acres to the agricultnral resources of the county. This it is intended to effect principally by the construction of a dam or dams at a point 25 miles southeastof Tucson, which would bring at least 100,000 acres out of sandy idleness into rich fruition. A detailed survey has shown the coniluent of the Eio Santa Cruz kn own as the Pantano Wash to be best and most economically available for irrigation supply by storing the freshets which come down the stream in both the summer and winter rainy seasons. The steady flow of water in this stream is so ^slight that it may be disregarded as an unimportant factor, reliance being placed entirely on the torrential flow of winter and summer to flU the storage basins. The first of the series of three dams recommended has been chosen at the point of meeting of the Cienega and Davidson's CaQons, some 23 miles southeast of Tucson. Here a dike of hard eruptive rook appe ars on the left bank, continues unbroken to the bed of the creek where it upholds the sands, and makes its surface reappearance on the right bank of the main channel. A second.dike is found on the right bank of the river bed and there is reason to snpiiose that it joins the former. Even though the bed-rock be not continuous the dam would yet have two abutments and a central pier of solid rock. A dam constructed at this point would have a total length of 1,052 feet and a maximum height of 67.5 feet maintained for 200 feet of length while the remainder of the length would need only 35 feet of height. The plan calls for a secondary dam 150 feet long with an average height of 6 feet. These dams would back np the . water in Cienega and Davi dson's CaEons in two rectangular sheets, 63.92 acres of an average depth of 20.50 feet iu Davidson's Canon, 210 acres of an average depth of 26.47 feet in Cienega Canon. The capacity of the reservoir would be 299,530,795 cubic feet. The objections to the plan a re twofold : First, that no adequate provision can be made for the removal of sedimentary deposits which would tend to reduce the capacity of the reservoir and ditchosj second, that the waters would cover the track of the Southern Pacific railroad for three-quarters of a mile. The second site recommen ded for a dam is 5 miles south of this point at a narrow part of the canon where the total length of the structure need be but 418 feet, the maximum height 43.43 feet, and the average height 40 feet. This would cover an area of 67.12 acres to an avera ge depth,of 22.37 feet with 65,391,298 cubic feet of water. This amount is 80 small that the reservoir would have slight value for irrigation directly. As a subsidiary work to the third collect- ing basin it is well nigh indispensable. The third dam is indicated for a point 2 miles further down stream and 7 miles below the junction of the Cienega and Davidson's Cafions. A dam built at this point would require a length of 2,640 feet, exactly half a mile, its niax- imnm height would be 73.96 feet and tor 2,000 feet of its length it would average 70 feet. The contents of the basin thus created would be 752,169,384.8 cubic feet of water spread over 514.23 acres to an average depth of 33.53 feet. Such an amount of water, if subject to no replenishment, could not be discharged in less than a year through a ditch 12 feet wide by 4 deep and' with a velocity of 29.42 feet the minute. The second dam is rendered necessary by the torrential violence of thestream at its serai-annual freshet and would serve to reduce its forceof impact against which it would be scarcely possible to structurally strengtbeu the long dam. The upper reservoir would also subserve the useful purpose of a settling basin for the lower reservoir. It is calculated that the permanent flow of the Pantano would supply one-half of the amount lost by evaporation from the surface of the reservoir. Goehiae County. — In the report of the Emigration Commissioner this southeastern corner of the territory is credited with having 23,500 acres cultivated in dependence on irrigation ditches. The aqueduct systems are not large but make up the average by numbers. In an interesting report on the post gardens at Camp Huachuca, Maj. Julius H. Patzki, U. S. Army, surgeon of the post, notes that with the single exception of potatoes a good supply of vegetables is grown under a very moderate degree of irrigation in the four months April to July. These gardens are in TanneY's Canon, 7 miles east of the post. This exception of potatoes deserves a particular mention to stimulate further inquirv or to lead to the institution of further experiments, because the head of this canon has been widely heralded as the first and almost the only spot on the A'merican continent where have been found specimens of this plant growino- in a free and wild state, alt hough it is known to be indigenous to this hemisphere. This iuteresting discovery which had been known to botanists for years was made in 1882 by J. G. Lemmon, a vendor of herbarium supplies. Prof. Edward Lee Greene, of the University of California, aud the leading authority on the botany of the Pacific Coast, thus writes to the point: " Two species of SoJaiiitm (potato) bearing tubers are common throughout southern Arizona and New Mexico. One (S. jameali) belongs to the plains, the other (8. fendleri) to the mountains. The mountain species is the one which to me, in the days when I was familiar with both, looked most like pur cultivated S. tuteroaun. Both are nearly related to it, yet doubtless both are specifically distinct. Their tubers, though very small, are used by the Indians as food. Just which one of the austral wild tuber-bearing sol anums is the parent of our cultivated varieties is a question which has baflled our best students of plant history and distribution for years past." In Eamsay's Canon near by the water supply is somewhat too precarious for gardening. At the mouth of Ash CaBon an atte-iipt at irrigation from a well is made. On a few ranches west of the post, and extensively in the valleys of the Eio San Pedro and Barbacomori Creek, crops of fruit, vegetables, grain, and hay are produced, all under irriga- tion, for which the water supply is ample. In the San Simon Valley the total ditch system amounts to but 2 miles lEEIGATION AND WATER STORAGE IN THE ARID REGIONS. 311 and its nse is confined to the alfalfa crop. The ditch system of the Sal phar Springs Valley amounts to bnt 4 miles and is mavnly applied to small gardens. The aquedacts of the San Fedro Valley comprise more than 45 miles of con- duits. The dams are temporary wing-dams carried away by almost every freshet, mere piles of brnsh and earth or bags of sand. In the Salphur Springs Valley, containing some 38 ,600 acres, the water underlies the surface between 15 and 20 feet. Wells have beea dug in many places, and their success is such as to encourage the expectation that the whole of the valley may be brought under oultivatloa by wells and motors utilizing the wind power. The tame is true of the valleys of the San Simon on the east and the San Pedro on the west, whose waters to a large percentage flow underground. Dams interrupting this flow by a trench filled with concrete would avail to reclaim many thon- sands of acres without ditches and without loss by evaporation. Two points only in the San Pedro Valley exhibit advantageous sites for reservoirs. About 15 miles north of Benson, at the Nigger Ben place, a dam 350 feet long and 40 feet high could be made to store 278,784,000 cubic feet available for the irrigation of 3,000 acres. A mile and a half above Charleston and 26 miles south of Benson a dam 400 feet long and 60 feet high would retain more than 300,000,000 cubic feet. The great drawback which will seriously interfere with the value of these reservoirs is the large amount of evaporation, which is so great that only a small part of the water would be available for the early summer months when of course the maximum is needed. Pinal County, — ^The irrigating system in this county, at present affecting 71,600 acres, depends on the Gila. It may utilize the San Pedro, and by wells and wind motors the subterranean flow of the Santa Cruz. Little has beep attempted so far, except at Florence, where the lands are irrigated by a dozen separate canals or ditches. A. T. Coltou, civil engineer, of Florence, in a succinct communication on the subject, notes that the Gila Valley, in the vicinity of Florence, contains about 750,000 acres capable of irrigation, of which 5,000 can be safely carried through a dry season by ditches, and the remainder might be irrigated from storage reservoirs. The same authority notes that the number of miner's inches (California standard) usually required for the irrigation of a quarter section of land in grain Is 10 for one crop, for alfalfa 30, and for fruit 20. He explains that his calculation is based on a con- tinuous flow of water. For example : A flow of 10 miner's inches is equal to 46,656,000 gallons on 160 acres in one year, or 291,600 gallons annually to the acre. This is equal to a rainfall of 10.8 inches, to which should be added 3.8 inches (the actual rainfall directly applicable to agriculture as observed in February, March, and April, 1889), making a total of 14.6 inches for one crop of grain, an amount considered ample. This water is to be applied to a crop of grain in three irrigations. New land will require about 50 per cent, more water for the first 2 years. The existing systems of irrigating ditches have been tabulated by a committee acting under orders of the board of supervisors of the county, as here follows: Gila system. Name. North tank, Moore's ..

It is situated 15 miles south of Florence and will have a capacity of 8,000,000,000 gallons, which it is certain will be replenished once a year and possibly twice. The main addition contemplated to the irrigation facilities of the county depends on the impounding of the waters of the Gila at the narrows known as the Buttes, about 15 miles above Florence. At this point the bluffs are precipitous and the gorge is not more than 200 feet wide at its bottom. It appears that a dam liSO feet high will 312 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. back the water abont 20 miles with an average depth of 75- feet for the whole distance. Immediately abov* ehe Bnttes the canoa of the river broadens, and at a distance of one-quarter of a mile it is as much as half a mile wide on the bottom, and for much of the entire distance it is a mile or more wide. The sides of the mountains surrounding this basin are broken by lateral uanons that add greatly to the contents. There can be ho doubt of the water supply being sufficient to fill this reservoir, vast as it is, for a glance at the chart of isohyetal curves will at once show its dependence on areas of large precipitation. Graham Counti/.— As before, Mr. Farish is authority for the statement that 47,000 acres in this county are cultivated by means of irrigation. In the absence of more definite information it is believed that such ditch systems as exist are small and depend on water drawn by gravity from thp ordinary flow of the Gila and on minor sources of supply. Acting Assistant Surgeon William Johnson at Fort Thomas in reporting on the post garden on the site of old Camp Goodwin, some 6 miles west of the fort, says that the supply of water is unlimited and is u'sed just as needed and in such quantity as seems desirable. Mr. E. B. Tripp, of ^Eagle Pass, reports on the Pueblo Viejo Valley that there annually goes to waste down the flooded Gila water more than sufficient to supply the entire valley could it be stored. Concerning the same valley of Pueblo Viejo Mr. Edward D. Tuttle, of Safford, submits an able and interesting statement. The valley lying on both sides of the Gila contains 150,000 acres, of which 50,000 acres can be irrigated by ditches tapping the Gila and 10,000 more by storage reservoirs, the best results being promised by impounding the Gila. Irrigation is necessary more or less the whole year around ; in general it must begin in February and C(mtinue until the middle of May for grain and into September for corn and fruit. Under the system now, in use, which he characterizes as wasteful, 40 miner's inches are required for a quarter section in grain, but if the reservoir system prevailed 10 inches would be ample. Fruit land for the first and second years would require 40 inches and after that 20 inches would suffice. In general the black adobe soils require water twice as often as the loams. ' Mr. Tuttle makes the following Buggestiohs, 'which are worthy of attention as the views of a ma* practically acquainted with the situation : " One general principle may be asserted. To ran an irrigating ditch over a given territory a certain strength of stream must be maintained, varied by' the fall and the absorbing capacity of the soil ; the greater the fall and the less absorbent the soil the smaller the stream need be. If conducted to the point where the irrigation is to be applied in a pipe or cemented ditch, one-tenth of the present amount would suffice. The expense of this method will prevent its adoption in the cultivation of ordinary crops which do not yiiild much profit. However, should it be demon- strated that citrus fruits can be profitably grown here, irrigation projects of an expensive character can be carried out by private enterprise, as land will become very valuable, but I have yet to learn that a single orange tree has been set out here. If citrus fruits are to be grown at all it must be in the thermal belt on the mesas, and not on the colder bottom lands. Since the best fruit lands are those that are now above any -water available tor irrigation I have more faith in obtaining artesian water or. pumping from wells than in irrigation under the reservoir system. If Government will appropriate enough to test the possibility of obtaining artesian water more goodcan be accon^ plished with a small sum than in any other way." Judge J. T. Fitzgerald, of Solomonsville, has prepared the following accurate statement of the existing canals in Graham County, with the length of each and the acreage under ditch.

Gila County. — In this mountainous county the estimate is made that 7,600 acres are cultivated in dependence on irrigating ditches. In the eastern part of the county within the San Carlos reservation there is an extent of arable land variously conjectured to amount to 200,000 or 300,000 acres. On this irrigation is carried on to a small extent by the Indian Bureau, and affects perhaps 2,500 acres. In the western half of the county there may be about 12,000 acres of arable and irrigable land in patches and small strips in the narrow valleys of Salt Eiver and Tonto Creek, -with a contracted area on Pinal Creek north of Globe. The few and small existing ditches are used to apply water to 800 acres. The board of supervisors of the county formally represents that it is a mining and grazing country, without agricultural possibilities, and protests against the proposed creation of a storage reservoir on Salt Eiver and Tonto IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 313 Creek on the ground that it will In no wise benefit Gila Countj^," within which it will lie, but on the contrary will destroy almost all the agricultural land of that county and will obliterate the only feasible location of a north and south railway to Globe, whose route has already been surveyed and traolis laid for 40 miles. Marieopa County. — This central division of the Territory has 321,000 acres dependent on irrigation already in operation and of this amount, about half is under crop. Of a total acreage aggregating 5,986,500 it has been computed after careful survey that 3,000,000 acres can be reclaimed by a judicious system' ol impounding the drainage aud storm waters. The existing irrigation systems depend on the Gija and the Salt Eivers, as appears in the follow- ing tabular statements. Salt River system. Name.

The Chamber of Commerce of the capital city, after examination of the several sources of water supply, has definitely determined to recommend that site which, as has been noted, has been the subject of a protest on the pait of the board of supervisors of Gila County. The site is on Salt River, at a point some 400 yards below the junction of Tonto Creek, where the river flows-into a box ca&on with sides perpendicular for the first 100 feet and sloping above at an angle of 4.5°, the bed of the stream being just 200 feet wide. A dam 200 feet high erected at this spot would back the water up Salt River for 16 miles to its oa&on through the Sierra Anoha. For 2 miles back from the dam the lake would be half a mile wide and 180 feet deep ; the next 2i miles would show a width of 2 miles and a depth of 140 feet ; the next mile would contract to a quarter of a mile in width, with a depth of 130 feet, and then would come a stretch of lOJ miles, having a width of 2 miles and an average depth of 70 feet. To this should bo added' the arm of the lake, which would be created in Tonto Creek for 10 miles, with an average width of IJ- miles avd 80 feet depth, and smaller arms in Finto Creek, the Sallamay, and others. This dam would impound in all 103,058,040,800 cubic feet of water, thus constituting it the largest reservoir in the United States. Yavapai County.— la 1889 the farmers of Yavapai County tilled 10,000 of the 4J,360 acres in their limits covered by canals and ditches. In addition to dam sites utilized at Date Creek and Bill Williams' Fork, which are intended to reclaim 50,000 acres, the only systematic irrigation attempted in the county was in connection with the dam of the storage company at Walnut Grove, on the headwaters of the Hassayampa, which was primarily designed for hydraulic mining. This reservoir covered an area of 527} acres, and received the drainage of about 500 square miles of territory, mostly of a monntainons character, the greater part of which consisted of bare granite rock, allowing a quick flow of water, resulting from melting snow and rainfall, to the reopiving reservoir. The dam which closed the head of the ca&on was 110 feet high, 135 feet thick at base, 12 feet thick, and 420 feet long on the top. Fourteen miles below this was a small service dam, 220 feet long and 44.5 feet high. On February 22, 1890, a flood of unprecedented violence, after 3 days of extremely heavy rain, completely destroyed this system of dams and suddenly poured down the gorge the contents of the reservoir, which had a storage capacity of 4,440,000,000 gallons. 314 IREIGATION AKD WATER STORAGE IN THE ARID REGIONS. It wa8 the intention of the company hefore meeting with the disaster of last February, which intention will be carried oat on the reconstruction of the works, to build a bedrock service dam some 38 miles below the storage reservoir for the purpose of raising water into*a canal of 10 or 12 miles in length, constructed to carry water stored above out ou the mesa between the Hassayampa and Agua Fria, than which there is no liner piece of land in the Territory. The river bed would be used as a conduit to the head of tfte canal. The necessary sub or irrigating ditches would be constructed to properly distribute the watei^ to ranches taken under the main canal. It was also their intention to construct other dams on the tributaries above, forming other reservoirs, in order that about 30,000 miner's inches of water could be drawn off daily aud utilized for irrigation purposes during the'irrigation season. One hundred miner's inches of water will irrigate about 160 acres of laud, much less being required after the same land is seeded to a permanent crop or set in differeut fruits. Thirty tbousaud miner's inches would irrigate in the neighborhood of 50,000 acres by proper care. Tlie flow of the Hassayampa during the storm, which resulted so disastrously for the Walnut Grove Water Storage Company, was, on close ealcuUtiou, 7,000 cubic feet per sacoud. There are about 7^ gallons to the cubic foot, and about 17,500 gallons in 24 hours make a miner's inch. A flow in the river of 7,000 cubic feet per second would give a fraction over 4,500,000,000 gallons in ^i hours. Apachie County. — The Commissioner of Emigration reports 6,900 acres u nder irrigating ditches and cultivation in practice upon all the land available. At Woodruff, on Silver Creek, the Mormons, who have there made a stake, have completed a reservoir which they operate with marked success, as is clearly proved by the thrift of the communities dependent on it. The distributing ditch is about 700 yards long before subdivision and supplies 3 miles of laterals which irrigate about 1,000 acres. ^The dam was washed away last spring and was not repaired in time to make the system available during this year. Two miles above St. John's there Is a small reservoir which covers 50 acres 12 feet deep and supplies water for some 3,000 acres in the neighborhood of the town. A small reservoir at Coneto has been in use for 10 years to irrigate 250 acres. At Snowflake, on Silver Creek, another small reservoir covers 50 acres to an average depth of 4i feet. The board of supervisors in reporting ou the possible development of irrig atiorf in the county confined its detailed examination to the valley of the Colorado Chiquito, between Springerville and St. John's, and reports six Bites avail- able for storage reservoirs. The first is 25 miles above St. John's, and is fed by a living stream, which would cover 600 acres 12 feet deep by building a bank 300 feet long and 25 feet high. The second site is 22 miles above St. John's, on Coyote Wash, where a dam 495 feet long and 100 feet high would cover 2,000 acres with 12 feet of water. This system could be utilized upon 30,000 acres of good land near St. John's in addition to 1 500 acres within the Wash. The third site is on the Colorado Chiquito, 16 miles above St. John's, at a point where a 20-foot bank 900 feet long would cOver 700 acres to a depth of 8 feet. The fourth site is at Salado Springs, where a dam 70 feet high and 600 feet long would impound sufficient water to irrigate 60,000 acres. At Padre's Lake, a mile above St. John's, a storage basin, dependent on the spring thaws, could be constructed by an embankment only 10 feet high and 1,000 feet long, which would cover 100 acres 6 feet deep. The last of the series is recommended for the mouth of the Zuui River, where a dam 80 feet high and 700 feet long would coyer 7,000 acres to an average depth of 35 feet, an amount which would suffice to keep 125,000 acres well irrigated. Mohave County. — There is little agricultural land in this county, and its uniform elevation above the Colorado militates to preclude irrigation except as applied to small pockets of loam in expansions of the caHon of the river. Mr. Farish credits it with 1,000 acres of irrigated land, all under cultivation. This estimate is doubled by Mr. C. M. Funston of Kingman. His report is that irrigation is practiced in but one section of the county and there only in a crude way. The ditches are maintained solely by individual effort and cover probably 2,000 acres. The reason for this state of affairs, in his opinion, is duo to the fact that there are no public lands in the county ; at least none have been surveyed by the Government and thus thrown open to selection. He estimates that there are 200,000 acres of irrigable land in the county, which will be rapidly taken up as soon as it comes upon the market. Tuvia County. — Of 40,000 acres under existing ditctes this county is credited with having cropped but 6,000 acres during the season of 1889, but it must be kept in mind that irrigation in the Lower Gila Valley is yet in its infancy. Of the canals now operated only one is completed according to the designs of the engineer, and the remainder are put to so much use as is possible in their incomplete condition. They all draw their supply from the Gila and are restricted in their sphere of utility to the bottom lands of that valley. The following table will give interesting figures concerning the most important ditch systems now in operation in whole or in part. The plans of the projectors, it should be said, contemplate the extension of some of these canals to compass a total length of 241 miles and reclaim 267,000 acres: Kame. Mohawk . Kedondo . Farmers. .

The head gate was situated ou the arc of a basin formed by a reef of solid rock reaching half way across the river and so subject to eddy currents that no sediment is ever deposited. A tunnel several hundred feet long was dug through a hill and thus the canal was led to the foot of the mesa and so to a valley 5 or 6 miles below. It operated well until the tunnel caved in and shut off the supply. The works still 1 eraain and could be put to use by a little oleariug in thfe dry bed of the canal and by facing the water-way of the tunnel to prevent that scouring of the soft stratum which caused the cave. . Two great systems of irrigation are proposed by the residents of the county, one on the Gila, the other on the Colorado. The Gila system looks to the building of a dam at Oatman's Flat, about 100 miles northeast of Yuma and just outside the county boundary. At this poiut the river cutting the southerly spur of the Big Horn Mountains exposes solid bluffs of dolomltic limestone from 110 to 195 feet high at a distance of 1,595 feet from each other. Here it is proposed to build a dam 100 feet high, resting its ends on these solid walls of rock. The water thus stored will back up a canon but half a mile wide for a distance of a mile and a half up stream ; then it will occupy Oatman's Flat, 3 milesjong by a mile and a half wide ; then, after narrowing to three-quarters of a mile, the basin will expand •■ to occupy Cottonwood Flat, 8 rniles long by 4^ wide, and after another constriction Gila Bend Flat for 8i miles. The area covered by water when it is just at the top of the dam is computed, to be 48.4 square miles, with an available depth of 35 feet after allowing for 7i feet of evaporation. This will store 47,227,009,600 culjic feet of water, which will prove ample to allow the daily withdrawal of 151,385 miner's inches for 6 months, an amount sufficient to irrigate more than 600,000 acres. The proposed Colorado Canal is projected to head at a point some 28 miles above Yuma. Here the river channel is cleft by Stevenson's Island, which acts as a dam to the waters and causes a rapid which is measurable as a fall of 4 feet in 600 feet of flow. This provision of nature it is designed to increase by art. A dam and lock wjll be erected at the island, which will not interfere with the traffic of the river, it being a navigable stream for 650 miles to the mouth of the Hio Virgen. This look wUl raise the water 13 feet above the low-vvater stage, both to enable the water to be spread over more of the mesa land and also to secure in the lock the functions of a settling basin in order that the heavier sediment may be kept out of the canal. From the lock at Stevenson's Island the canal with a minimum width of 50 feet will be carried above the bottom lands and flumed across the Gila with the possibility of extension into the State of Sonora. The amount of land to be reclaimed by this canal is flguied at 175,000 acres, thus apportioned : 25,000 acres in the upper angle of the Gila and Colorado ; bottom and valley lands between the Gila and theMexican boundary, 70,000 acres ; and adjoining mesa land similarly situated, 80,000 acres. This canal, affecting as it does land within the scope of the Gila canals, will prove no rival, but a complement to that system, inasmuch as the Colorado high water comes at the period of mi nimum supply of the Gila. In every dam to be built provision should be made for the removal of sediment which will tend to fill up the storage basins, a tendency which will develop with remarkable rapidity. The causes which have been of the utmost value in preparing a soil worthy of being irrigated will exert an influence prejudicial to the practical application of the measures of irrigation. The streams will "not lose their burden of silt and detritus by being diverted into storage basins, but they will deposit it within the basins, where the waters are held practically motionless. It would be extremely unwise, therefore, to construct reservoirs which are not provided with ground sluices sufficient in number and so placed as to cover the whole bottona of the reservoir in their prisms of scouring action. EEOAP^rnLATION. Thus in brief review have been presented the operations of irrigation now practiced in Arizona, and a sketch of snch extensions of the principle as seem so feasible to those most intimately concerned that they feel justified in the hope that they will be put into execution. Fuller accounts of these matters will undoubtedly be presented by those whose duty it is to handle the engineering and economic problems involved. This brief review, however, is eminently pertinent in the present record, because it shows that the phenoinena which constitute the proper objects of the meteorologist's study have been appreciated by the agricultural community and have been thus satisfactorily corroborated by removal from the abstraction of mere theory into the domain of practice and daily use. It may not be out of place to present a final summation of the results attained by the meteorological student in the investigation of that part of the arid lands comprehended within the territorial limits of Arizona. They are these : (1) Twice each year there occurs sufficient aqueous precipitation in Arizona to reclaim every acre of land worthy of snch reclamation. (2) The coefficient of evaporation though absolutely high yet is relatively so small in comparison with the total fluid contents of tie actual and projected storage basins that it may be economically disregarded as a vanishing quantity. • (3) A measureless amount of foot-pounds of available power is daily going to waste in the winds which blow over the land. This power rendered efficient by wind motors will suffice to utilize the large subterranean rivers which are known to immediately underlie large areas of rich land. With the presentation and the proof of these propositions which are the only components of the reclamation problem properly within the sphere of its activity the Signal Service is satisfied to turn its data over to others whose duty it shall be to apply to varying eoonomio conditions the conolosions heieia reached. Appendix No. 66. climate of new mexico, wits particular reference to the rainfall and tempera-, ture and their influence upon the irrigation problems of the territory. Signal Office, War Department, Washington City, Deceniber 5, 1890. Sir: I have the h6nor to submit herewith the second of the series of memoirs' apon the climate of Sates and Territories -^ithin the arid region which you ordered me to prepare, the memoir dealing with New Mexico, as detailed below. ^ Iq submitting this memoir I may be permitted to enter upon a brief comment upon the finished work. J may say that I have a general and particular acquaintance with the Territory, derived from extended travel on duty or for pleasure. From this quite intimate acquaintance with the 'general features of the Territory, I am justified in feeling able to utilize to good advantage the climatic records filed in this office. The tables in the appendices exhibit the .records of rainfall and temperature noted by intelligent observers at the several stations which have been maintained in New Mexico for longer or shorter periods. In some cases otherwise valuable records are briefly interrupted, and in such instances (ndoubt- edly locally induced rainfall of an inch at Cebolleta, in Valencia County, Socorro, In the county of the same name, and Fort Cummlngs, in Grant County. An area of more than 2 Inches of monthly rainfall appears upon the divide between the Gila and Colorado watersheds, closely encircled by a 1-inch curve extending prominently in the direction of Fort Cummlngs, and the system reachesinto the greater area which rules in Arizona at the time. At the same time H. Ex. 287 21 322 IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. there broadly appears in the central valley of the Pecos, from the Jaan Dios to the Rio Hondo.and overrnDning the slight divide into a portion of the Canadian, an indefinite area of 1-inch precipitation which extends from the Sierra Blanca and may be attributable to that mountain influence. Another 1-inch curve cuts off in the northwest corner of the Territory the drainage basin of the San Juan, including the basin of the Chama and the waters of the Jemez. This and kindred phenomena will receive further consideration iii the discussion of the theory of the seasonal rains. In January the precipitation at the three points above noted has conformed to the general average of the Terri- tory, showing that the high precipitation of December was local and temporary. Meanwhile the area of 1 inch of fall has advanced northward over the western parts of the counties of Bernalillo, Valencia, and Socorro ; in effect it is coterminous with the Colorado watershed and can not be traced across the continental divide. The higher pre- cipitation continues with apparently close restriction to the lofty summits in Socorro County which part the Gila from the Colorado Chiqnito. In February the isohyetals, which in Arizona begin to give signs of breaking down into scattered local areas, have become markedly strong in New Mexico. The high summits of the Gila divide are closely marked with isohy- etals of the same high figure. The curve of 1 inch generally rules west of the continental divide, and is unmistakably indicated as having crossed the summit and penetrated almost to the Eio Grande trough, though with slight intensity. Beyond the eastern wall of this trough a curve of 1 inch appears at Puerto de Luna and Las Vegas, in the Pecos basin, and is clearly due to local influence which is able to seize upon and magnify the faint and early forerunners of a cli- matic period which will scarcely make its general appearance for some weeks later. The March charts show the precipitation, which nowhere greatly exceeds an inch, confined to the Gila-Colorado divide in New Mexico and Arizona, and somewhat retracted from the Rio Grande. It is to be noted as an important preface to the temporales of the summer that a curve of an inch is plainly drawn about the summits of the Sierra Blanca on the eastern divide, extending northeastward almost to Fort Sumner and Puerto de Luna. By April the winter rains have definitely ceased in both New Mexico and Arizona, except that the curve of 1 inch may be drawn interruptedly upon the 'highest sum mits of the divide between the Gila and Colorado. In the Atlantic watershed east of the eastern divide a peculiar area of considerable precipitation is noticed, and, in contrast with the general absence of precipitation which prevails over the rest of the Territory, is remarkable. The isohy^al of 1 inch follows the high summits of the Sangre de Cristo range until they sink to the plateau of 4,000 feet, thence trends southeasterly to include the headwaters of the Pecos as far as Gallinas Springs, thence sharply curving upon itself extends northward over the Raton range. The isohyetal of 2 inches is restrictively drawn on the upper waters of the Canadian from Springer northward. This also will receive consideration in the discussion of the theory of these rains. In May the flow of the rivers tributary to the Gila and the Colorado Chiquito condition the provisional drawing of a 1-iuch curve upon the Sierras Datil and Latil. East of the Rio Grande the 1-inoh curve appears as a long loop from Colorado down over the Sierra Blanca. Within this a narrow 2-inch curve is drawn about Las Ve^as. Now by composition of these monthly elements it is possible to trace the general area of the winter rains to such an extent, as they concern I^'ew Mexico. The greatest force of precipitation is plainly limited upon the summits of the continental divide and its western slopes; from collation of the system as it appears in the adjacent districts of Arizona there is valid reason for the assumption that the maximum precipitation is to be found in the Gila basin and the Carrlzo and ZuBi headwaters of the Colorado Chiquito. The curve of 2 inches is drawn across the Mimbres. plateau and Mesilla Vallfey and the lower plains in this territory and Texas until it reaches the valley of the Pecos. The eastern wall of this valley it follows along the 4,000-foot plateau until the valley contracts; thence it passes over the divide into the Canadian basin and across it near Fort Bascom and northerly into the strip of public land. The curve of 3 inches follows that next lower as far as the Rio Grande Valley. Up the sharp western wall of this valley it is drawn as far as Socorro, where it expands to include the Rio Puerco as far as Laguna and Albuquerque in the valley of the Eio Grande, whence it returns southerly upon the 5,000-foot eastern wall of the valley as far as the Organ mountains. Here it crosses the Sierra San Andreas and skirts the Malpais lava fields, the tongne of the 4,000- foot plateau which projects northerly from Texas. Around the southern flank of the Sierra Blanca it passes to the floor of the Pecos Valley, which it follows northward and maintains the same general direction into Colorado. A second appearance of the curve of this weight is found in the extreme west of the territory narrowly drawn south of Fort Defiance. The 4-inch curve in one system is drawn upon the continental divide reaching into Arizona by the Gila Valley on the south and the Sierra Latil on the north. In the other system it enters from Arizona north of Forth Defiance' crosses the Mesa de los Lobos into the Rio Grande Valley above Albuquerque, and thence follows the next lower curve in its long course out of the Territory.' The 5-inch curve associated with the Arizona rains with but a narrow interval runs concentric with its companion curve of 4 inches upon the Gila-Colorado divide. Curves as high as 17 inches are indicated upon the mountains so included. In the eastern member the 5-inch curve entering from the north upon the western face of the Sangre de Cristo range preserves a southern inclination as far as the 5,000-foot level beneath the Sierra Blanca, beneath which it curves eastward and then northward along the w est wall of the Pecos Valley, passing west of Puerto de Luna Gallinas Springs, and Fort Union, it returns into Colorado west of the upper Canadian. On the northern part of this area is found a considerable area of 6 inches, and in the southern part curves of 6 and 7 inches are drawn about tbe high levels of the Sierra Blanca. Bains of SMmmer.— Attention must now be renewed upon one feature of the orography of New Mexico and throughout the present examination of the summer precipitation it must be held distinctly before the mind that the Territory comprises two slopes, one westerly, one easterly, and between their highest ridges is a narrow trough. Hence arises the necessity for considering these rains in eastern and western members. IREIGATION AND WATER STORAGE IN THE ARID REGIONS. 323 The winter rains appear in New Mexico a .month later than in Arizona, the summer rains a month earlier and persist a month later. In 'June the western member of the precipitation, that controlled by the Continental divifle, appears in a curve which is almost beyond doubt locally induced, embracing Forts Webster, Cummings, and MoEae just without the Gila watershed and immediately to leeward of some of its considerable peaks. The eastern member lying upon the Atlantic watershed is most distinctly marked. The curve of 1 inch foUovrs the line of the Eastern divide, oieeping to windward to include Albuquerque and Santa- F<5, and sweeping eastward in a broad curve embraces the Sierra Blanca, all of the Pecos basin but its southern edge, and the greater portion of the Canadian Basin. Within this is iiicluded a curve of 2 inches drawn along the 5,000-foot contour from the heights of the Sierra Blanca northward to Fort Union, where it opens to include the counties of Mora and Colfax. In July the rains are strongly marked upon Arizona, and extending into New Mexico show the western member of its rain system in a high stage of development. The curve of I inch drawn broadly across the southeastern corner of the Territory shows that the Arizona precipitation has fairly crossed the Continental divide. The 2-inch curve runs determinately in the bottom of the Eio Grande trough from Mesilla to Spcorro, by the south it follows out tfte contour of 5,000 feet westward' to reenter Arizona, and by the north joins the system of that region along the 7,000-foot contour. The curve''oT 3 inches may be cousidered as being definitely superirapysed upon the Gila basin. Crossing the narrow trough which sharply bisects the Territory, it is found that the heights which were in Jane nearly the western limit of 1 inch of rain now distinguish the curve of 2 inches, which in its eastern Minb traces the contour of 4,000 feet and leaves the region across the eastern edge of the Canadian basin. The curve which in June - limited the maximum precipitation of 2 inches has now been advanced to become the 3-inch isohyetal of July and opening at its upper end includes the northeastern highlands of the Canadian basin. ■ Within this curve a loop of narrow limit bounds an area of 4 inches, which extends from Fort Union to Las Vegas, becoming more intense southerly. This arrangement of the eastern and western members may be reasonably held to present the type of summer rain in its most perfect development just prior to the obliteration of some of Its characteristics. In August, when the rains in Arizona hkve reached their greatest force, the two members in New Mexico have so closely approached that they overlap and fill the Bio Grande trough. The isohyetal of 1 inch of the combined system, by, reason of the marked increase in precipitation, is forced entirely out of the Territory, and but one appear- ance of any curve of this weight is found, and that is a small cusp obscurely drawn on the headwaters of the Zuiii River. Recurring now to the western member, it will be seen that the curve of 2 inches follows its accustomed line in the bottom of the Rio Grande Valley; running west w ard across the Mimbres plateau and the mesas of western Bernalillo "County. As in June, the 3-inch curve is drawn in correspondence with the divides which partition off the Gila Basin. Of more limited extent a curve of 4 inches is,indioated for the Pacific face of these divides. A 5-ineh curve is to be drawn about the region for which Silver City is the determining station and Fort Tularosa conditions curves as high as 8 inches. In the eastern member the curve of 2 inches remains nearly symmetrical with its July shape, but has pushed southerly into the Mexican State of Chihuahua and into Texas, thence recurves to inclose tlje Pecos Valley on its west side, and passes from the Territory with the Canadian River. The curve of 3 inches has undergone considerablis alteration. It is now drawn southward at the 9,000-foot contour on the Taos range, and retains the same direction as far as the Sacramento Mountains ; where it turns north about the flanks of the Sierra Blanca and into the Pecos Valley, passing through Gallinas Springs; thence it runs north and out of the Territory over the Raton range, and after penetrating toward the Sierra Blanca passes east with the lower curves. Prom the summits of the Sierra Blanca a loop of 4 inches includes Puerto de Luna, and the 4-inoh loop of the month before has retracted to the im- mediate vicinity of Fort Union and Watrous. By September these seasonal rains are perceptibly breaking in Arizona and undergo considerable loss of intensity in New Mexico, where the two members of the system have drawn apart. The 1-inch curve is drawn from the Raton ranges southerly through the Pecos Valley, across northwestern Texas, the Mesilla Valley and the Mimbres plateau. A shallow arc of a curve of the same weight is drawn upon northern Taos County, opening toward the San Juan park in Colorado. A general 1-inch curve outs off the northwestern corner of the Territory entirely west of the Continental divide. The 2-inch curve is now upon the western wall of the Rio Graude trough, from Mesilla to the Valvprde, and unites westerly with the Arizona group across the plains of San Augustine and Mimbres plateaus by north and south respectively. In the valley of the Rio Grande an area of less than 1 inch is found with Las Lunas and Albuquerque as its foci. Curves as high as 3 inches are restrictively drawn about the Lagnna Mountains. In the eastern member the 2-inch curve narrowly extends from Sierra Blanca to the Santa F6 range. October shows Arizona definitely ont of the influence of the summer rains, except for scattered instances of persistence around isolated mountain masses. New Mexico, however, exhibits its characteristic duality in the mem- bers of the system which are diffuse and weak. Each member shows but the isohyetal of 1 inch. In the western member it follows the characteristic track at the west wall of the Rio Grande Valley and out over the plains of the Mimbres and the Luni plateaus. An area of 1 inch extending from Colorado includes the headwaters of the Chama, Jemez, and San Juan. The close of October definitely marks the passage of the temporales as systematic rains out of the map. By composition of the monthly elements as before, the duality of the iemporalea is clearly indicated. The western member has appreciably intenser precipitation ; the eastern member undoubtedly contains an absolutely ' greater amount of water, since its precipitation, though less intense, affects a greater area. The line of demarkation is distinctly drawn along the Rio Grande Valley. 324 lERIGATION AND WATER STOEAGB IE THE AEID REGIONS. The 4-inch or minimam curve appears in the southwestern part of the territory, and with closely adjacent curves of% and 6 inches enters from Arizona in the Gila Valley, skirts the mountains which look upon the Mimhres plateau, and passes out into the lower Rio Grande Valley. These three curves rule the Meailla Valley with their greatest in- tensity. Curves of 4 to 7 inches appear briefly in the basins of theCarrizoandZuHiandcurvesof 5 to 7 inches depend from Colorado on the northern boundary upon the head of the Chama. On the western member curves from 8 to 15 inches are drawn upon the mountains of the Continental divide and the Sierras which part the Gila from the Colorado. The systematic curve of 7 inches parts the two members. Drawn in from Arizona in the valley of the San Fran- cisco River it runs over the mountains between well-raarlced curves, both higher and low«r, and engages the Rio Grande Valley at Fort Selden. Up this valley with a decided general persistence alons; the western wall it is drawn to include Chama and Embudo and thence returns southerly without leaving the immediate valley and passes out into Texas. In the Valverde it incloses areas of 5 and 6 inches and similar areas of 4 and 5 inches at Las Lunas, with a 6-inch area extending nearly to Chama. On the eastern member the limiting curve is that of 8 inches, which, with those of 9 and 10 inches, enters from Colorado on the west face of the Taos range, follows the eastern divide quite to the southern boundary, and then returning northward in the valley of the Pecos passes to higher levels east of Fort Snmner and thus out of the north- eastern coruQir. The 11-inch curve is limited to the territory. It appears upon the higher levels west of the Canadian River and on tde caHon coilrse of the Pecos and in this portion of its area includes curves as high as 15 inches, includ- ing Las Vegas and Fort Union. Below this area the two members of this curve draw close together near Puerto de Luna and then expand to cover the Siprra Blanca, where appear ditfuse curves up to 14 inches at Fort Stanton. Theory of the rains. — The discussion of the rain phenomena heretofore presented belongs properly to treatises upon pure meteorology. Yet it may not be improper to devote here a short space to the examination of the theory of these periods of precipitation in order that it may appear that the climate and rainfall just noted will be found reasonably constant, since they are based on fundamental facts in nature. The rains of winter and those of summer are radically distinct in type. In winter the humid winds are drawn across the region under discussion by the influence of low areas over regions near or remote. In summer the winds rush from all sides toward the heated mountain masses and the precipitation resulting therefrom is distinctly local. In the winter the continental lows hang for days upon the Rooky Mountains or sweep eastward with varying velocity. In their train and toward the areas of diminished pressure which are their center the winds are drawn np the western face of the mountains and ultimately from the oceanic stores of moisture. The type is a simple one and well characteristic of the Pacific olima;tlc group. Step by step the humid winds ar(i drawn over graduated plateaus and extrusive suramita, and at each higher step discharge so much of their moisture as is a surplusage over the satura- tion amount of atmosphere of a given tenuity at a given temperaturS. There is nothing violent in these systematic drafts of humid air from the sea toward the continental cyclones; the air is chilled by the seasonal causes which make the winter climate; the earth surfaces soon become largely covered with snow and their radiating influence is thus mechanically obliterated; the air lies in practically even strata of uniform temperature. The humid wind is drawn along these ruling conditions, on every plateau it discharges down to the point of saturation; the diminution in absolute amount o£ moisture is constant and large; by the time it overlies the Rio Grande trough its last available moisture has been condensed by the heights of the continental divide and sifts down to leeward. Practically desic- cated the current reaches the summits of the eastern or Atlantic divide; it has but little rain to deposit for the im- mediate agricultural benefit of the plains; such precipitation as is induced appears as snow which forms a storage reservoir whose supply is constantly utilized until July. Therefore are the winter rains confined in the main to the. western member. Before considering the somewhat complex nature of the temporales or seasonal rains of summer it will be necessary to examine the nature of the mountain as a determinant of climate. By whatever influence induced, a'tmospheric strata drawn inirom the sea and passing over land surface are sub- jected to an influence in the shape of mechanically directing guide planes. At the sea level and the mean temperature of whatever isothermal zone may be under discussion, calm air is in a position to take up and hold in suspension moisture up to the point of saturation. Thereafter any change in barometric pressure coextensive with, and pro- duced by, elevation to a higher plane, or any change in temperature however induced, alters the point of saturation, leaves the air mass with more moisture than it can hold, and precipitation results. The ideal presentation of the ease is that of a smooth plane rising from the sea upon which a current of air is directed; as the air body is deflected by* the plane it undergoes expansion sufficient to cause rain when subjected to pressure change due to elevation and temperature change brought about by the same cause; it accordingly in theory precipitates its surplus moisture, that is, the excess over its constantly altered amoant of saturation. Practically this ideal case is modified by local altera- tions of pressure within the mass, and at its face, which makes a more or less violent impact upon the opposing terrestrial mass, an influence which is at its minimum value when the air body moves over a level surface, at its maximum when the air in its course meets with extensive perpendicular cliffs, a condition which Arizona affords in a high degree to the air movement under immediate discussion. Yet another terrestrial factor intervenes to modify the ideal case, the factor of heat radiation from the body over which the air is drawn, and this is a most important element which may be fairly said to dominate the entire system of the temporales. When the elevating plane over which the air is drawn is covered with snow, this factor is in its lowest terms. Snow reflects the incident solar heat back to the air through which it has just been transmitted, and as the air is highly diathermauous it is very little affected by.this original and reflex passage of heat, which further- more is near its minimum during the season when precipitation takes the form of snow. An excellent reflector of heat, snow is also a notably poor radiator, and forms a screen which prevents in a large measure the diffasiou of the IRRIGATION AND WATER STORAGE Df THE ARID REGIONS. 325 heat which the mountain mass has collected by absoiption and stored during a warmer season. It therefore appears that the temperature of the surface of a snow-clad surface of elevation differs but little from the absolute temperature of air normal at the same elevation. Over a region governed by such an elevation it is most likely that the superterra- nean planes of temperature and saturation are evenly distributed. In such case the induced air body raised by the guide plane of the mountain slope into successive planes will move continuously and with the least' disturbance, and will lose of its humidity only such a minimum amount as will suffice to reduce it to the saturation point of each suc- cessive plane, and thus will carry its maximum to be precipitated on distant regions in its appointed course. With the yanishiug of this screen of snow the conditions proportionally alter. The surface of elevation, with its soil and rook masses, ceases to reflect the incident heat ray of the sun, but absorbs much of it. At the same time it radiates the heat which it receives, currents are formed in the surrounding air, and the mountain becomes a focus of activity, about which are currents rushing rapidly skyward and a lateral indraft to supply the place of the air withdrawn by this action of convection. The air passing the snow-clad mountain is raised to the minimum elevation which will enable it to pass beyond; its precipitation is the minimum, its reserve is available for higher ranges. The air, influenced by the radiating mountain mass, is forced to the highest elevation which the upward current can reach, as is shown by its frequent precipitation as hail; it is subjected to the greatest change of pressure and tem- perature, its excess moisture and consequent precipitation reaches the maximum, it is almost desiccated, and on even higher ranges beyond can causg no precipitation. All these theoretical features are observed in the New Mexican rains. One other point remains to discuss before proceeding to the practical application of the theory, and that is the drift of falling rain increasing with the altitude of condensation. While the advance portion of the moving body of air is deflected upward it yet retains the momentum of its general onward progression, and as soon as the resistance of the mountain is lost the momentum is translated into movement. This gives to the rain condensed at the same . point an inertia which it maintains in its descent to the earth, and thus appears as a precipitation well to leeward oi the influence which produced it. The precipitation will be found nearer its originating mass in the case of the winter rains than those of the summer for this reason : In winter the general movement of progression will be felt as soon as the mountain opposition is removed, that is to say at its summit, and the inertia communicated to the falling rain is exerted through a miuimum vertical distance, the tangent of the angle remaining constant and the perpendicular at the minimum, so must the base be at its minimum. But in the summer action of radiating mountain masses the humid air is lifted witji the utmost rapidity to the maximum height, where it probably meets with the geqeral south- west circulation of the upper atmosphere which communicates the inertia; the angle and its tangent are still con- stant; the perpendicular being increased, so must the base be extended, and the rain meet the earth far to leeward of its origin. At the same time in connection with the drift of the summer rains there are certain phenomena which argue a drift to apparent windward. The explanation involves the peculiar character of the origin of these rains. They are not the result of an onward movement of humid air; they are the upward convection of meeting currents from all directions. Forced upward as in a chimney, these currents are likely to emerge on all sides of a bounding circle, and some may emerge so far to the westward as to appear to progress against the prevailing wind. Examination of the temporalea will show all these influences at work progressively, thus necessitating the study of the system by monthly periods even as it has been found convenient in anticipation of this discussion to exhibit the phenomena of the rains month by month during their continuance. In June the western member of the dual rain system may be viewed as upon a plane of elevation which is prac- tically snow clad. The 10 or li feet of snow precipitated in the winter upon the high lands of the Gila Basin and adjacent summits in Arizona endures to this date as a broad non-radiating surface. Above this lie air strata of the simplest natnre. The humid air being raised to the higher strata without commotion suffer the minimum discharge or their humidity. Passing across the Eio Grrande Valley as still efficient bodies of humidity they encounter the higher altitudes of the eastern divide, which are also snow clad, more of their moisture is condensed at altitudes of 10,000 feet and more. Drifting to leeward from that great height some of the rain is revaporized in its descent through fully a mUe of air, and what does reach the earth is vaguely diffused over large areas of small precipitation. By July the completeness of the snow covering upon the western member has begun to disappear, and from the influence of radiating centers which are steadily increasing in number and magnitude the air strata are faulted, to adopt the terminology of the geologist. The humid air body is therefore unevenly lifted and disturbed, some of its moisture is precipitated, and since the system is yet largely snow clad the fall is close at hand, and the isohyetals are drawn with close parallelism to the mountains. At the same time the melting snows restore humidity to the air. Crossing to the eastern member snow is still fouud of sufficient extent to dominate the climatic conditions, yet even here the air strata begin to be faulted and the humid air to be exposed to an increase of discharging influence, and inasmuch as that air has received an 'accession of humidity from the melting snows of the western member the rain becomes general to leeward. August shows the western member carrying but little snow as a general system of elevation, and what does exist is confined to the loftiest summits and northward gorges. The air strata have by this become extremely distorted, and the motion of progression over the heights is greatly interrupted. As in July the humidity is subject to an increment dependent upon the rapid melting of the snow, but as the mass is now a radiating body the humidity is passed rapidly to very high altitudes and makes a high precipitation upon the immediate region. The eastern mem- ber has definitely become a ridge of great radiation and intense activity of convection. The humidity subjected to condensation in the high altitudes is apparently lessened in amount through the greater precipitating activity of the western member, and despite the greater force of condensation the amount of actual rainfall varies but little from that of the month before. 326 ILIEIGATION AND WATER STOEAGB IS THE ARID REGIONS. In September the two mountain masses are fully developed as ridges of radiation and convection, the available humidity has been almost exhausted, and although the condensation takes place at high altitudes yet the general air temperature is so much elevated that the practical effect of height on temperature is considerably lessened. The rainfall is materially less ; it appears as indefinite areas of slight intensity, and thus the temporales disappear. Evaporation. — The climatologist is expected to supply all data pertaining to his especial study Which modify the economic features of the region under examination. The inquiry has so far concerned itself with the passage of moisture from slcy to earth. It is now in order to investigate briefly the reverse operation, the passage of moisture from earth to slsy. Not much attention has yet been paid to the measurement and record of evaporationi which must considerably modify the estimates of engineers on the hydraulic capacity of their storage basins. Eecent atmido- metric research authorizes the provisional drawing of the curves of equal evaporation across the Territory. The curve of 70 inches of water evaporated in the year somewhat corresponds on entering the Territory with the Pecos- Canadian divide and the Sangre de Cristo Eange ; thence in a narrovr tongue within Colorado it returns southwest- erly, cutting oflf the San Juan drainage basin. The curve of 80 inches sweeps in across the Pecos Basin as far as the end of the Santa F6 Modntains, where it sharply recurves and passes out along the Gila divide. The curve of 90 inches is drawn in a broad sweep from the southeastern corner of the Territory to pass out by the Gila divide, and after running a narrow loop over Arizona and the southern half of California, it returns into New Mexico for a short distance along the southern border. The wind and the underfloiv. — In addition to the water which is passed across the country permanently or intermit- tently in streams regard must be had to the numerous springs which are an evidence of an underground supply. To these subterranean waters of the great plains has been given the name of the Underflow, and for convenience of refer- ence and to coordinate this work with the researches of others the name may be retained. Yet it m\iai be rigidly stated and strictly understood that in the present state of knowledge no competent evidence exists to prove that this underground water supply partakes in any sort of the nature of a stream sufficiently to authorize the use of the word flow. In individual instances a flow may be proved in continuation of the above-ground flow of the lost rivers characteristic of the region, but that the general body of underground water has any such progression Is certainly not proven. In genera] it may be said that the existence of conditions which accompany the occurrence of springs will war- rant the opinion that water-bearing strata must underlie the depressed basins and valleys of New Mexico. Hence by digging to sufiScient depths and reaching an impervious layer water may be found. The experimental wells bored near Santa F6, Las Vegas, Baton, and Doming prove that such strata exist, as they have been penetrated ; but as the Cretaceous beds through which the wells were sunk an not favorable in so far as the Impervious clay beds which they contain are not known to be continuous, or as no synclinals are known to exist, the prospects for a copions flow of water as was hoped for could not have been very promising. Only by reaching the Carboniferous can copious water beds be found, but the estimated depth at which they may be expected is certainly not less than 2,000 and per- haps 3,000 feet. Much better promise attends the sinking of tubular wells to moderate depths. This is meeting with success even around the Jornado del Muerto and west of the Eio Grande. On the Cejita de Galisteo, south of the Galisteo creek, in the Manzano valley, on the Florida plains, and in the Pecos valley water has been reached at depths varying from 25 to 50 feet in what ^as until of late an absolutely dry country. It is noted that water is found at lesser depths in proportion to distance from the mountains. Water of this sort is by some distance below the level of the land to be irrigated. In nature it is useless, it possesses but the possibility of utility. To overcome this distauo e demands the application of work, it involves the consideration of the economics of power. With the present high development of pumping machinery there are no mechanical obstacles in the way of raising this water to such a height as will make it available. The question is simply one of economics; it must be examined from the financial point of view and the operation will be successful in proportion as the interest upon the sum invested in the plant plus the cost of operation approaches the minimum ratio to the gross earnings of the farm. The cost of the plant, the di;iving of the well aud the purchase-of the pumping machinery can not well be reduced below a certain limit without impairment of efficiency; the variable quantity is the cost of operation and upon this point suggestions may well be received from the student of climatic science. The wind in constant motion overhead may be translated into work and when available will supply the most economical power aud reduce the cost of operation to the minimum. To this end modern mechanical skill has devised wind motors which work in the lightest airs; which adjust themselves by automatic devices to every change of direction; which by simple machinery of self-reeflng appliances regulate themselves to every increase of power and with no more attention stop when the necessity for the operation is temporarily suspended and resume when need arises. The only question which needs examination is whether the wind of any given region is sufficient day by day to operate the motors. In the failure of mechanicians to supply the adequate data the examination must be made by comparison of wind velocities with those noted in regions where windmills are considered to afford satisfactory power. In the San Joaquin Valley in California it has been found that windmills are most effective agents, and are efficient so long as the wind does not fall below 4 miles an hour. Daring the months of May, June, July, and August the wind averages 7 miles an hour, and rarely falls to the minimum limit of efficiency. Viewing this velocity as the datum ^oint the following table of average wind movement at two typical New Mexican stations of observa- tion will show what use may be made of windmills in irrigation : IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 327 Hourly wind movement • Stations.

At this point the relation of the Signal Service to the qneation of the irrigation of the arid lands properly determines, and it becomes the duty of the engineer to deal with the facts hereinbefore presented. As a scieutifie bureau of record and review it has presented the facts of climate and has discussed them. It has shown the amount of rain which falls upon New Mexico in every month of the year. It has indicated the periodicity of the rainfall and the varying amounts precipitated on different regions. 'It has shown the amount of evaporation which wiU. diminish the hydraulic value of reservoirs. It has directed attention to the wind as a source of power. In the discussion of the data presented it has gone into the argument sufficiently to show that the peculiarities of rainfall are constant and may be relied upon. With this ends the strict province of the Signal Service. Yet for the sake of completing the popular record it may be found advisable to pa«8 in rapid review the works of irrigation already in operation within the Territory and such others as are planned for speedy installation.

In other words, there is only 37.1 per cent, of this irrigable area aotnally under ditch. Under this heading of irrigable only the first bottom lands immediately adjoining the streams haye been taken into consideration. The great mesa lands intervening between water courses are to be considered as grazing lauds which will become agri- cultural only when water is applied to them by high line ditches. This class of land amounts to 51.8 per cent, of the remaining area, or 20,993,528 acres. These valuable statistics have been compiled by Mr. H. Hartman, of Santa F6, who has not only a most accurate acquaintance with all parts of the Territory in detail derived from personal survey of the geology and topography of the country but has also enjoyed access to the most reliable records. The figures which he has supplied, are, there- fore, the latest obtainable and are accurate to July 1, 1890. It will now be in order to oandertake a brief examination of the several counties.

The western portion of the county, amounting to perhaps a third of its area, lies within the watershed of the Little Colorado. The great bulk of the county is in the Eio Grande trough and a narrow pro- longatiou extends over the eastern divide into the Pecos basin ^nd,alraQ8t to the river of that name. It is natural, therefore, to expect a variety of climatic constants, which is so great as to necessitate the consideration of the county in accordance with the division just made. In the western part there is received about 3 inches of rain'in winter and 8 in summer, and the amount of evaporation is below 70 inches annually. In the central part the winter showers do not much exceed 4 inches and the temporales are less than 8 inches. Evaporation exceeds 70 inches and in the imme- diate valley of the Eio Grande may amount to 80 inches. The eastern prolongation is so small and unimportant that its climatic conditions need no express review. The valuable lands for agricultural purposes are to be found in the valleys of the Eio Grande, the Eio Puerco of the east and the Eio Puerco of the west, the Eio Jemez, the Galisteo, the Santa F6, and Tuerto Creek. In addi- tion, there are numerous springs which feed small streams and assist in agriculture. Yiticulture yields excellent returns under irrigation and is enlisting considerable capital.

Lying entirely in the Pecos drainage basin, the county receives in summer 8 to 12 inches of rain and lies tributary to a region of 14-inoh precipitation in Lincoln County. In winter its rainfall amounts to between 2 and 4 inches. Its evaporation is somewhat more thau 80 inches. The eastern half is covered by the Staked Plain, but in the west there is rich agricultural promise, and the Pecos and its tributaries furnish more water than perhaps any other stream in the Territory. The land is level mesa of the utmost fertility and covered with a volunteer growth of gramma grass. Springs abound and lakes are many, and all these have been utilized to supply water through gravity ditches to many farms. Two extensive irrigation systems are now in operation in the county on the valley lands near Eoswell. One is that conducted by the First New Mexico Eeservoir and Irrigation Company, which impounds the flood waters of the White and EI Capitan Moun- - tains and conducts the water thus stored 18 miles to serve lands which need but water to blossom into unexampled fertility. The Pecos Irrigation and Investment Company has built a dam across the Eio Hondo and a second on the South Spring Eiver, from which runs a main canal of 35 miles length to serve lands as far down as a point 15 miles below the Eio Feliz.

Its eastern boundary is fringed by an area of 3,000 feet of altitude, and its western boundary is drawn along the lofty ridge of the Taos range. It shows but slight traces of the action of the winter rains, but in April and May the valley of the Upper Canadian, as far south as Springer, is influenced by a precipitation which does not appear elsewhere within the Territory, except that its area extends down into Mora with diminished intensity. For the 2 months this rainfall amounts to some 3 inches. The summer rains are felt in this valley up * Not obtainable. lERIGATION AND WATER STORAGE IN THE ARID REGIONS. 329 to 10 inches. The surface ia greatly varied with plains, valleys, buttes, and mesas. The arable lands are found In the bottoms of all the rivers and creeks which rise in the western part of the county and in the valley of the Cimarron, in the extreme northeast. Irrigation works of considerable magnitude are restricted to the Maxwell grant, in the western part of the county. Here two systems are operated by the Maxwell Land Grant Company. The Springer system draws its supply from the Cimarron Creek, 13 miles northwest of Springer, and has completed and in operation 47 miles of ditch and 6 reservoirs, and is designed to reclaim 20,000 acres. The Vermejo system draws its water from the Vermejo River and distributes it through 17 miles of main ditch upon 30,000 acres, with an S-mile lateral to Crow Creek. The laterals of these two systems already measure more than 150 miles. doSa ana county. Acres.

It consists of a table land of 4,000 feet, with mountain ranges 20 to 50 miles long and 10 miles wide, between which intervene dry plains from 20 to 80 miles in width. The two curves of 90 inches of annual evaporation include the region and must be calculated into the capacity of all storage works. In winter the county receives little rain, aggregating scarcely more than 2 inches in the Eio Grande Valley. The tem- poralea yield it 6 inches and upward in the valley, and an indeterminate though probably slightly greater amount upon the eastern plains, which may amount to 14 inches at the northeast corner. , Surveys have been made for the purpose of locating a site for a reservoir to store the waters of the Eio Grande at a point 3 miles above El Paso. Bat, apart from certain features of this b^sin which might be considered to exist disastrously to New Mexican interests, the sys tem needs no consideration here, from the fact that its benefits must be confined to the adjoining States of Texas and Chihuahua. 'The most highly developed portion of the county is the far-famed Mesilla Valley. This spreads out, upon the riparian strip of 3,000 feet altitude from a point near Fort Selden to the Mexican boundary, some 40 miles. The low level land is from 3 to 5 miles in width ; the eastern mesas have a width of 15 miles to the foothills of the Oregon Mountains, and on the west these mesas extend indefinitely towards Deming. The low level land has been partially under cultivation for several hundred years and has a wonderfully rioh^oil, capable of production under irrigation from the muddy Eio Grande of all cereals, and especially all semitropical fruits and vegetables. The high level land of the Mesilla Valley to the northeast opens upon the Jornada del Mnerto, which is one of the most interesting and peculiar conformations of land in the arid region. It is a broad, fertile plateau, at an alti- tude of 4,500 feet on the thirty-third parallel, lying somewhat in the form of an ellipse, rising gradually from the eastern side of the Eio Grande near San Marcial several hundred feet, and then sloping downward and southward for about 100 miles, with an average wi^th of 40 miles, bounded on the west by the Sierras de Fra Cristobal and Caballo as far as Eincon, and on the east by the San Andreas, the Organ, and the DoSa Ana ranges. The soil is rjoh and highly productive, having been formed by the deposits from the adjacent mountains by the action of ages. It abounds in good sites for dams to store the torrential flow of all its arroyos, and its rainfall is sufficient to fiU every such basin. EDDY COUNTY. Acres.

Occupying the south- east corner of the Territory, it is prominently marked by mesas of 4,000 feet, which advance so prominently upon the river as to narrowly restrict the 3,000-foot plain which characterizes the middle Pecos in Chaves County. In com- pensation, however, its river bottom is a broad flat of fertile soil upon the 2,000-foot level, the only example of the kind in the Territory. Its evaporation amounts to more than 90 inches, and its summer rainfall is less than 10 inches, thus forcing it to entire dependence on irrigation from the Pecos and the many streams which rise in the Sierra Blanca, the most important being the Eio Pe&asco and Seven Eivers. The Pecos, through 40 miles of gravity ditches, supplies the Laguna Vista property of the Hagerman Irrigation Company. Twelve miles higher up a ditch is flnmed across the river to supply the town of Eddy and gardens adjacent thereto. The Pecoa Irrigating and Investment Company will, on the completion of its system already far advanced, furnish water for 75,000 acres on the west side of the river and 50,000 on the east, 40,000 above Seven Eivers, and 50,000 below Black Elver.

This, the southwestern corner of the Territory, is ragged and mouutainous in the north, but in the south is covered with plains and mesas of 5,000 feet altitude. Evaporation is high and the county lies entirely within the two branches of the atmidometric curve of 90 inches. In the winter rains it receives between 1 and finches on the plains, which fall rapidly, increases in the mountains to at least 5 ijiches and probably much more ; in summer the rainfall on the plains is 4 to 6 inches, and in the mountains undoubtedly reaches 1.5 inches, while at the same time the snow of the winter precipitation is evenly becoming applicable to agriculture by its melting. In the Gila Valley and the valleys of its tributaries are pockets and strips of arable land which never need irrigating. On the Florida plains and particularly near Deming there is a region of country which is known to be 50 miles wide and 100 miles from north to south, where an inexhaustible supply of water can be reached by wells no more than 50 feet deep. Wind- mills for raising this water to the surface for irrigation purposes have proved entirely satisfactory. LINCOLN COUNTY. Acres.

It includes the Sierra Blanca, which has been noted as a great determinant of the rainfall of the Atlantic watershed, and is naturally controlled by the strong influence of that range. In winter it receives from 3 to 7 inches of rain; the temporalea pour down 14 inches upon it in the summer. Its evaporation is about 90 inches. The face of the country is varied, being composed mainly, and especially in the northern part, of extended plateaus interspersed with valleys and mountains. The char- acter of the soil is various, the la^er portion being sandy loam, with considerable areas of chocolate and black soil. Farming depends on irrigation, and under such treatment the soil yields a generous return. The arable lands are for the most part found along the Cienega del Macho, the Eio Bnidoso, the Eio Bonito, and the upper courses Of the Eio Jelia, Peflasco, Sacramento, and Pinos Creek, heading on the east face of the divide, and^Nogal Creek, Three Elvers, Eio Tularosa and Lost Elver, on its west face.

Its eastern edge is a staked plain of 4,000 feet, the central part is 5,000 feet high, and the -western portion, with a general height of 7,000 feet, is crowned with the lofty summits of the range. Except this portion the county is composed of fine, rolling, grass country. Evaporation here is greatly reduced and averages some 70 inches. The winter rains are felt here more generally than in the southern portion of the same watershed ; the eastern half of the county receives 2 inches in this season and the western half lies within curves of from 3 to 6 inches. In summer there are from 8 to 10 inches of precipitation on the eastern half, and the western part receives as high as 15 inches. Wells are dug to water-bearing strata within a few feet, and wind- mills are found quite practicable. Irrigation is generally practiced, and the ditches are supplied from the streams and from the many natural depres- sions on the plains, which with very slight labor are turned into reservoirs.

Evraporation is low, being under 70 inches. The winter rains are felt in the county nearly 4 inches, and in summer less than 8 inches.- The river flow available for Irrigation is most uniformly drawn from the precipitation upon the mountains in Colorado. Since the streams are permanent,' irrigation is in a hi^h state of development. The more notable existing works of irrigation are these : The Grand canal taken from the Animas Eiver, near Aztec, and extending toward the La Plata, for the reclamation of 10,000 acres near Farmington ; the Coolidge ditch drawn from the Animas, near Farmington, and covering many thousands of acres near Olio; the Caiion Largo ditch drawn from the south side of the San Juan and applied upon a large tract opposite Bloomfield, and the High Line ditch drawn from the La Plata.

It is on the 4,000-foot level of the Llano Estacado, in its eastern portion ; the 5,000-foot plateau covers the greater part of the county, and the northwestern one-sixth lies upon steep mountain slopes. Evaporation may amount to between 70 and 80 inches. The rainfall conditions are much the same as in the general Canadian basin. In winter the eastern portion is in receipt of 2 inchfes, which rises tq nearly 7 inches through the valley of the Upper Pecos; in summer the curve of 8 inches is drawn midway of the east and west extent, and the remainder receives abundant rain, amountingto at least 15 inches. The snow-eapped mountains of the western portion feed constant streams, the Canadian, the Pecos, Gallinas, Sapello, Tecolote and their tributa- ries, which abundantly water the county. The land subject to irrigation along the valleys is much greater than a casual observer would suppose. The soil is almost invariably rich and yields abundant returns to farming operations. There are many districts where farming is known to be practicable without irrigation, and the success noted in these is causing others to experiment with every prospect of success. Upon the rich vegas of the West the windmill and the well may be counted on to extend the sphere of agriculture. SANTA V± COUNTY. Acres.

Of greatly diversified surface the county is uniformly above the 7,000-foot contour, rising rapidly to Mount Baldy, 12,652 feet high. The winter rains are felt at the city of Santa F6 to the extent of 4.52 inches, an amount which rapidly increases with the eleva- tion under the favoripg condition that all the mountain precipitation is in the form of snow, which affords an even supply of water to the streams until nearly the end of summer. The temporalei are most efficient npon the lands of the county, yield 10.17 inches in the capital and nearly double upon the mountains. These storms are violent upon the summits, often accompanied with thunder and not infrequently with hail. The arable lands of the county are along the beds of the creeks and have been sufficiently brought under culture to show the soil as fertile as the most exacting farmer could demand ; the extent of land, under cultivation is small as vet but it is clear that storage systems may be relied upon to make a great incre ase in farms, orchards, and gardens. The water courses of the county all flow westward to the Eio Grande and may be enumerated in order from the north. They are Canada de Chimayo, Nambe Creek, Tesuque Creek, Santa F6 Creek, Galisteo , Apache, and Cafionoito Creeks. The possibilities of irrigation have been more carefully studied here than elsewhere in the Territory, and this study has. gone into the closest details of hydraulic potential of the water courses. The sums only need be presented here. First come land cropped without irrigation, amounting to 18,440 acres ; bottom lands along running streams, now partially irrigated and practicable to irrigate by the construction of ditches and dams of small size to act as diversion dams amount to 48,080 acres ; bottom lands available under small reservoirs, 13,940 acres ; uplands available under small reservoirs, 16,840 acres ; larger reservoirs would reclaim of the lands at present strictly pastoral 78,060 acres on the Santa F6 plains, 20,360 acres along the arroyos of San Cristobal and La Jara, and an nndetermined amount abont the Cafiada de Ortiz.

Agriculture is most systematically pursued in the bottoms of the Eio Grande and such of its oonflueiits as afford an efficient water supply. It is clear that wells of moderate depth can be made to reach abundant subterranean waters on the high f lain west of the river, and that wind force may be trusted to make them available.

The winter rains discharge a scanty 3 inches upon the Rio Grande Valley in its most restricted sense, and the curve of 3 inches is scarcely found short of the contour of 7,000 feet, well west of the river ; thence, however, the rise in precipitation is a sharp one to 17 inches at old Fort Tularosa,. and mnch more upon the mountains is commonly observed but never accu- rately registered. Similarly in summer, while the 7-inch curve of the seasonal fall is found close to the eastern divide, the curve of 8 inches clings closely to the actual channel of the river, the curve of 10 inches comes but little below the high mesa, and the mountains receive 16 inches or more. Agriculture is practiced at chosen spots on the head- waters of the Gila, where no irrigation is needed, along the Bio San Francisco, which has attained some distinction for its wheat crops, and in the valley of the Rio Grande, where the same conditions exist as in Sierra and Dona Ana Counties.

Similarly of the summer rains its quota is 8 inches and more in the west, a little less than 4 in the valley, and 10 east of the Antonio Sandoval grant. The Rio Grande Valley has been cultivated under ditch for many years, and has never failed to yield a satisfactory return. East of the river there are many fertile valleys rapidly coming under settlement, and in the little known western portion it seems clear that there are considerable districts of good soil which may be farmed. Appendix No. 67. climate of california and nevada, with particular reference to the rainfall and TEMPERAT-URE AND THEIR INFLUENCE UPON THE IRRIGATION PROBLEMS OF THE TWO STATES. Signal Office, War Department, Washington Cily, December 6, 1890. Sir ^ I have the honor to submit herewith, in accordance with your orders and the resolution of Congress, the memoir which has been prepared on the climate of California and Nevada as a conditioning factor of the irrigation problenf in tiie arid region, In the appendices there will be found a complete presentation of the rainfall and temperature data of the two States, derived from eyery reliable source and brought down to the date of the inquiry. It was found in examining this material that interruptions existed in some otherwise valuable records. In such cases, where the gap was shor^, the continuity has been restored by the interpolation of mean values, but it shonld be said that in these two States there has been little necessity for resorting to this justifiable approximation. Extreme caution has been nsed in making such interpolations, and wherever they occur they have been clearly indicated by the use of brackets. The charts amount to a graphic presentation of the same data in such form as to be readily grasped. The curves of evaporation have been retraced by Professor Russell from^ data in Iiis possession. The contours of elevation, an essential feature of the maps, were furnished by the U. S. Geological Survey. Concerning the text of the memoir it may be proper to renew attention to the official position which I have occu- pied upon the Pacific coast as aiding me to discuss the climate 6f the two States from an intimate professional and personal acquaintance acquired while doing duty oa the Pacific Slope. Daring this time there was published among the papers of the California Academy of Sciences my preliminary review of the Weather Types of the Pacific Coast. The theories somewhat provisionally propounded in that review have been subjected to rigid examination in this memoir; I have, it is believed, supported them by the data as practically proved for the Pacific Slope, and I have advanced the principles at least of an interesting climatic theory which may be provisionally extended over the whole country. I have borne in mind that while the inquiry is expressly directed upon irrigation the Signal Service can properly concern itself only with the climatic features of the two States and of these the precipitation in particular. The other climatic features are bat collateral to this main topic and have been considered only to ^uch an extent as is warranted by their influence upon the rainfall. The memoir has been cautiously elaborated and not a single state- ment has been presented which does not appear to the writer distinctly upheld by the existing data. Yet at the same time it is well understood that, at some later period, the accumulated record may become so much more representa- tive of the entire region that the present work may be subjected to keen analysis. In such an event it is trusted that while some of the statements made in the memoir may be found to need modi- fication, the general results will receive confirmation. It may in this connection be well to note that upon an important portion of the area under examination where records of precipitation are wanting, namely, the high Sierras, it has bee^ possible to establish the isohyetal curves with considerable accuracy by Hall's stream-flow records and Russell's study of the existing glaciers. In fine, it is to be said that all portions of the two States have been discussed with the utmost impartiality, modified only by the amount of the data contributed by each region. The examination of the arable but dry land has necessitated the stndy of regions of higher precipitation which by .storage of the river waters might be made con- tributory to the lands below. Very respectfully, W. A. Glajssford, Second Lieutenant, Signal Corps, Signal Officer and Assistant. The Chief Sigital Officer. CALIFORNIA AND NEVADA. Irrigation does not present itself to the Californian farmer and capitalist as a mere experiment, as a problem whose solution demands the risk of any loss of time and labor, as a thing to be cautiously considered and timorously advent nred. Here is a State in which all are agreed that the irrigating ditcji is the life of the valley, and the only point which at all needs deterraipation is the amonnt of water available. Here has developed an agricultural popur lation who look upon rainless skies not as a curse, but as the best gift of nature, since they have themselves a control 333 334 lEEIGATION AND WATER STORAGE IN THE ARID REGIONS. over the weather beyond the reach of men elsewhere. In 40 years the flume of the miner has grown into the ditch of the farmer, and brings to light more wealth now than when its stream was directed upon the auriferous gravels. In these 40 years irrigation has extended until it may now be deafly seen to approximate that condition in which all the water available is put to use upon the soil, and no more can. be obtained. The limit is in sight even though it has not quite been reached, the limit of water which may be drawn from streams by gravity ditches. The future must deal with other sources of supply a,nd other means of utilizing existing sources. This is the condition which is seen to confront the future of irrigation in California, and it is with this condition that any must have to do who enters into the consideration of the irrigation problem of this State. In other districts of the so-called arid region, it is necessary to show" that the soil will repay the introduction of water, that crops can be made to grow on rainless plains, that in short irrigation is an experiment worth the trying. California, however, has settled all these minor points long since, and now the question is pure and simple to determine what amount of water is available for the iraigatlon of lands of latent fertility. While other States and Territories'are just entering upon the practice of irrigation in its first stage of supply through^the gravity ditch, California has nearly passed through that stage and is now looUing upon the second stage, the era of water storage on a large scale. The engineer is called upon to show what streams ma^ be stored by damming their flow, to calculate the amount of water which may thus be reserved against the time of need, and in general to fix the limit of available supply. That question is now engaging the careful attention of those to whom it is of vital importance, and they are examining it in all its bearings. In their investigation they find that the economic limit of available water has a direct and close depend- ence upon the limit fixed by nature. This limit it becomes of paramount importance to determine, and for this determination recourse is had to the Signal Service, which, with its records covering the climatic systems of the whole country, is the final authority. ' The economic limit is the ability of the engineer to devise means for catching and storing the water on the earth, and drawing upon the streams beneath its surface. The natural limit is the amount of water which reaches the earth, in other words the rainfall. To the consideration of this single point the present inquiry is restricted, save in so far as it is found necessary to examine collateral lines of research which may alter or condition the amount and character of the precipitation. «. At the outset and before entering upon the more purely climatographic examination, it will be found necessary to devote some attention to the geographical physios of the two States, California and Nevada, which form the subject of the present memoir. This course is necessary because the land with its valleys and summits is not merely passive in receipt of the precipitation which falls upon it. It is an active agent in producing precipitatiou and in conditioning its amount and intensity. The mode of this activity will be presented in this discussion together with such statement of its causes as is justified by the available data. It is only by comprehending well the constauts of nature in the sea on the one hand and the mountains on the other that one can comprehend at all the character and amount of the Californian rainfall and its individualities of annual periodicity. PHYSICAL GKOGRAPUY. Two influences dominate the climate of California, radically dissimilar in every particular, combining in ever varying forces to produce the resultant which is recorded by observers of the weather. One is the sea tending always to charge the air with moisture, the other is the mountain mass tending always to discharge the moisture from the air. The combination of these two activities in varying proportions is responsible for the variation in the araouut of precipitation, including months of drought. It is necessary to consider these two active and determining forces not merely in their resultant, but so far as is possible by resolution into their component forces as well. In the present state of knowledge the resolution can not be complete, yet the extent to which it can be made affords interesting results. The mountain factor, — The States of California and Nevada abut upon the maximum extension in latitude of the Cordilleran system, by which designation is inclusively implied all those ranges, basins, and valleys, which in a looser description are often spoken of as the backbone of the continent and considered to include everything from the eastern ranges of the Eocky Mountains to the Pacific Ocean. Between the parallels of 35° and 40°, this system attains not only its greatest breadth but its greatest general elevation ; it extends from eastern Colorado across four States and into the ocean, where but a few miles from the Californian coast it breaks short off from the continental shelf and plunges to abysmal depths. Not only is its width greatest between these parallels and therefore productive of its maximum influence upon the general circulation of the atmosphere, but also by the massing of many of its extreme heights within these same limits it exerts such violent influence of perturbation as is due to sudden uplifting of air bodies to great altitudes. Thus in Colorado there is a chain of peaks all rising to a height of more than 14,000 feet, of which Pike's Peak is the eastern outpost ; Utah and Nevada form the Great Basin on a general level of 5,000 feet ; in California the Sierra Nevada has its p eaks of 14,000 feet as well as Colorado, and at the very edge of the sea is another range of mountains lower than the Sierras, yet of markedVnfluence upon the climate and the rainfall in particular. These systems within the limits of the two States now under examination may properly claim more detailed investigation. The characteristit^ orographic feature of this region is the Sierra Nevada, and it is as well the predominant climatic instrument both for California to which it gives the rain and for Nevada from which it withholds it. The geographer and the geologist unite in considering this the most interesting and important link in the Cordilleran system, and the climatologist must unhesitatingly and without reserve give adhesion to their judgment. In brief description it is a long and elevated mountain chain, on the whole the most conspicuous on the continent. It displays IREIGATIOK AND WATER STORAGE IS THE ARID REGIONS. 335 Its greatest promiaence when viewed from the west, becaase ou this side it falls almost to the sea leyel, while upon its eastern slope it merges in the general high altitude of the interior plateau. But it does not, however, border immediately ou the oceau, since for all its course there lies between its foothills and the sea beach a chain of lower mpnutains kuown as the Coast Ranges. 4^thongh the Sierra Nevada contains one summit higher than any yet .determined within the United States, and in general preserves its individual character with more simplicity than any of the Eocky Mountain ranges which form the eastern wall of the Cordilloran system, its altitude is rather under tUan above some of those ranges. If the popular limitation be followed, which marks tlie northern end of the Sierra Nevada at Mount Shasta and its southern end at Mount San- Jacinto, the length t)f the chain may be giv^n as about 600 miles. Such a limitation, based merely on the superficial appearance of continuity of elevation is erroneous. The really continuous core of the range, that portion which is due to the simultaneous upheaval of homogeneous mountain matter, is marked by Tehachapi Pass for its southern limit and thence stretches away northerly for 4.30 miles to Lassen's Peak. Its breadth varies from 75 to 100 miles, and tfiis element displays a certain not entirely fortuitous correlation with the altitude, since each declines proportionally toward the north. The Pacific slope is long and gradual. .The pastern slope is characteristically precipitous and short for the reason that at the elevation of 5,000 feet it encounters and is lost in the general level of the Great Basin. For half a degree north and south from the parallel of 37° the range attains its greatest height, culminating in Mount Whitney with its 14,898 feet. Many peaks come within 1,000 feet of this great height, and the very passes are more than 2 miles above the level of the sea. From Whitney to the north there is a slow decline in altitude, but so gradual is it that ihe geneial elevation of 11,000'feet is carried aloi^ unbroken for more than 100 miles, almost to Tuolumne County, and the 9,000-foot contour extends still further north, almost to Lake Tahoe, and the line of track of the Central Pacific Eaijway at Summit crosses the range at an elevation of a few feet less than 7,000. In the middle region of the range the slope is about 100 feet to fbfi mile, and the slope from ridge to valley is about 70 miles long. A section drawn between Visalia and Owens' Lake shows much bolder sculpture. The average slope to the passes is 240 feet to the mile, and to the peaks fully 300, this on the west. The eastern slope at this region displays its greatest bluffness, and falls away abruptly as much as 1,000 feet to the mile between the summit of Whitney and the lake 10,000 feet below. The western flank of the Sierra is deeply scored by precipitous caBoris, narrow at the bottom, ateep on the sides, with a slope of 30° by no means uncommon, and anywhere from 1,000 to 3,000 feet below the general level. With progress toward the north these canons become steadily more and more distinctive features of the Sierra. In that extensive area of the north where volcanic formations have spread with great uniformity over the mountain flank and form an even and almost level surface, the deep and sharply cut canons appear in most marked contrast with the plain in which these gorges have been engraved. From Nevada County north the granitic core of the range is almost universally overlaid with eruptive material and comes to light only at the bottom of the deepest of these water-worn gorges. At Lassen's Peak, which has been no^ed as in strict definition the northern limit of the range, begins a level volcanic depression from which Mount Shasta rises 70 miles northwest. North of Shasta the mass of elevation becomes known as the Cascade range, and is continued beyond the limits under examination. Mention has already been incidentally made of the fact that between the foothills of the Sierra Nevada and the Pacific shore line intervenes a series of mountain ranges. These, the Coast Ranges, are sufliciently important in their relations to the precipitation to merit more close consideration. The most important part of the Coast Ranges is that which fences off the great valley of the Sacramento and San Joaquin Rivers from the sea. In this portion of their' length, where they may be clearly distinguished from all series of inosculating elevations, they have a length of fully 400 miles, and in width vary from 40 to 70 miles ; in this particular it is to be noted that the eastern limit is fixed with considerable precision of definition at a practically constant distance from the western limit of the Sierras; the expansions are uniformly made by encroachments upon the sea. The system comprises a multitude of subordinate ranges, some large and^sorae small, but almost all distinguished by names bestowed upon ,them during the former Spanish occupation of the country, with a few Indian names yet preserved for characteristic peaks. The general trend of the sub-ranges as of the system at large is witli a tendency toward parallelism with the coast. In proportion to distance froni San Francisco, where the system is broken through at sea level by a gap but a mile in width, the summits and the general elevation are found to be higher, and this is true both north and south. It is remarkable, too, that the ranges south of San Francisco display a much more cohereuff system than north of the bay. Prom Mount Hamilton the ridge of 3,000 feet elevation continues without interruption and almost in a right line to the Tehachapi country and its coa lescence with the same level of the Sierra system. North of the bay the ranges do not attain this height uutil far in the north, and In general are much less simple. Between the north and south members of the coast system, and a little east of the gap, Monte Diablo rises as an isolated and commanding peak, and is the most prominent mountain in the State outside the Sierra system. The inosculation of the Coast Ranges with the Sierra system both at north and south is complete and interesting. The heights of the Coast Range which group themselves in Trinity County about Mount Yallo Bailey swing in upon the Great Valley, and at first through the outlying range of the MoCloud Mountains and later through the main mountain mass enter the Sierra elevations somewhat to the south of Mount Shasta. Topographically the union is complete, it is only by comparison. of rock constitution that any distinction can be drawn. The same is true of the southern inoscnlation in the counties of San Luis Obispo and Kern ; orographically it is complete and uniform, geo- logical study alone avails to mark the lociis of 4)artition. A third series of elevations rises to considerable heights in the southern part of the State, and it is altogether uncertain to which of the northern systems it is to be referred, whether it prolongs the Sierra Nevada or the Coast 336 lEEIGATION AND WATER STOEAGB IN THE AEID EBGIONS. Range. For oonvenienoe of refeience it may be distingaished as the Soathern Coast Range. It contains two mem- liers following different angles. The northern member Is drawn southeasterly from the Tehaohapi rej^ion, where it is attached to the conjoint northern systems ; reaching its greatest elevation and maximum width at the San Ber- nardino Peak it becomes less important as it is traced beyond and soon sinks to comparatively ob^cnre hills upon the desert plain stretching away toward the head of the Gulf of California. From the San Bernardino Peak the second member follows the coast and develops as the characteristic range of Baja California. Entirely east of the Sierras, Kevada is included within the Great Basin except that for a short distance at its southeastern boundary it enters upon the Colorado Plateau, which here has lost many of its prominent characteris- tics. The Great Basin is a high plateau upholding many monntain ranges with a general direction of north and south and considerable height above the valleys which occur between. As a rule these mountain ranges preserve their individuality and at least twenty such masses are to be numbered across the State. Having thus indicated the orographic skeleton of the country it comes next in order to examine the valleys infolded between these mountains. As it is the greatest, so is the Great Valley of California the most important; it frequently takes the names of the rivers which traverse it and is known in its northern portion as tlje Sacramento Valley and in its southern half as the §an Joaquin Valley. It is fenced on the east by the Sierra Nevada, on the west by the Coast Ranges, and at north and south by the coalescence of its side walls. Between these walls it has a length of about 450 miles and maintains the average breadth of 40 miles, taking in the lower foothills so far as they are available for agriculture, and thus contains some 18,000 square miles. The valley is almost completely surrouoded by high mountains and the only breach in the wall is at San Francisco midway of its length, and at the water level this gap is less than a mile wide. In the Coast Ranges are many fertile valleys which vary greatly in size and conditions according to position. North of the bay of San Francisco the valleys of the immediate coast are as a general rule abundantly watered but very much restricted in area. Two such may be mentioned as of greater area than the others, Eel River Valley and the Hoopa Valley of the Klamath and Trinity Rivers. South.of this gap the important valleys of the shore are some- what larger than on the northern coast but not so well watered, as will appear iu the examination of that branch ot the subject. The valleys well within the Coast Ranges are far larger and more important, and here again a distinction is to be noted between those of the bays north of San Francisco and San Pablo and those south. North of the bay the valleys uniformly open into the Sacramento Valley and each has a uame which has nearly the value of a trade-mark in the markets for farm, orchard, and vineyard produce. Such are the Sonoma and Napa valleys opening upon San Pablo Bay, Vaca and Capay Valley opening directly upon the Sacramento Valley, and north of this latter a series of smaller, or, in the language of the country, pocket valleys. South of the bay on the dry eastern slope of the Coast Ranges not a valley is to be found of any moment. West of the summits are to be found several fertile valleys. Of these the valley of Santa Clara and the Alameda open on the bay of San Francisco, and the valleys of the San Benito and the Salinas open on the Pacific at the bay of Monterey; each is large and the latter is particularly well watered. The valleys of the Southern Coast Range are uniformly fertile and of obscure boundaries, and have considerable available area, in which they resemble the valleys tributary to the Sacramento Valley. Notable are the valleys of Santa Ynez and Santa Monica, the rich valleys of Los Angeles between Cahuenga and San Juan Capistrano, and the equally rich though more distinct valleys of San Diego. A word'has already been said incidentally of the Sierra valleys. Upon the Sierra side of the Great Valley the tributary valleys are in the main small and ummportap.t ; they soon contract upon their available area, and at but a short distance away from their months they have assumed the appearance of rugged caQons whose only value to the agriculturist is in proportion as they are found to afford available sites for storage reservoirs. Within the ranges of the Sierras the valleys are for the most part impracticable and partake of the character which finds its highest ex- pression in the Yosemite Valley. On the eastern face of the mountains the valleys are uniformly canons of steep grade and denuded bottoms. Nevada has a peculiar banded system of mountains and irf similarly striated with valleys intervening which are deep and persistent. These valleys are in general sinks of playas and their lower portions are frequently occupied by pools whose size is dependent on the amount of precipitation during the foregoing rainy season. Two such sinks are larger than the others, the sinks of the Humboldt and Carson, and these two are not only upon the same level but often united and thus mingle the drainage of the northeru portion of the Great Basin with the precipitation upon the eastern slope of the Sierra Nevada. Southeast of the decadent portion of the Sierra system and south of the Nevada plateau occurs a considerable area of low desert land, in general less than 1,000 feet of altitude. At one point there is in this desert an area with a length of 60 miles quite below the level of the sea, of which the lowest portion is 263 feet below. The Oceanic faetor.—Thia presentation of the mountain masses of the region under study has been made for the purpose of showing what influences may be counted on as constantly exerted to discharge the moisture from the atmosphere. Another influence is constantly exerted to charge the atmosphere with moisture and this influence should be examined in its turn. It is found in the Pacific Ocean which washes the entire coast of California and makes one notable irruption within the continental mass. The largest of all the oceans, the Pacific, is least subject to perturbing influences of a local character. Its con- ditions are constant over large areas, its currents both of wind and water are drawn in broad sweeping' curves in which extent of space and time of passage serve to override all mere local or temporary modifications. Thus it is enabled to present almost the ideal problem of oceanic circulation and to array upon the climate of California and in lERljGATIOlfr AND WATER STOEAGE IN THE AEID REGIONS. 337 a modified degree npon that of Nevada, a few m^ses of simple influence which become involved and diflScnlt of study only through the continental disturbances. Without interruption that part of the North Pacific Ocean which may be considered as modifying the climate of California stretches away over very nearly 100 de$;rees of longitude. To the west it is bounded by the extreme Orient, the islands of Japan with their northern projection over the Kuriles to the coast of Kamtchatka and their southerly connections with the Philippines. The northern limit is drawn by the Aleutian Islands and the eastern border is the shore of North America. To the south no consistent mass of land appears to hem this ocean in, yet the barrier is none the less strong because it may be measured only with the instruments of the meteorologist. It exists at the thirtieth parallel of north latitude. Below this bounding line is the region of the northeast trade wind and the westward drift of the equatorial current, and these two serve sufficiently to bound in wind and water the great basin above. It is a basin within these limits, a rough ellipse having a major axis of 100 degrees of longitude and a minor axis of 25 degrees of latitude. It has its characteristic systems of circulation both of atmosphere and sea. The strongly individualized ocean current of the res;ion is the Kuro Siwo. Developed from the cumulative prog- ress of the equatorial drift aod directed by the rapid alteration in the plane of the sea bottom and the trend of the Asiatic coast, this warm stream moves across the whole northern Pacific. Occurring in a broader sej, it shows several important differences from the Gulf Stream — it has a slower motion, its warmth is not so strongly contrasted with the water through which it flows, and the wind blowing counter to its course frequently avails to deflect it or even check it entirely. Its eastern development and dispersion has been for years a battle ground for theorists, and even now it is impossible to say definitely that it reaches any part of the Californian coast. The winds upon this basin are of the system of the Passage Winds, which are developed upon the surface of the earth by the descent from high altitudes of upper currents. In general these winds vary with the latitude from southwest, westerly, to northwest. It should be noted that these winds begin to appear about the parallel of 30° north, and that at first they are a practically dry wind, but presenting all the best conditions for absorption. - CLIMATIC PHYSICS. There have been now presented to consideration the two grand factors, which in a broad sense may be said to determiue the climate of California and Nevada, and to differentiate the varying climates of the several districts into which the region is divided by nature. This presentatiou has been made strictly In the terms ol physical geography; the inquiry will now proceed to examine the interacting relations of these two factors of the climate, and more especially the rainfall. . Tfte (Jordilleran injiuenoe. — The Californian parallels lie entirely within the northern zone of the Passage or Anti- trade Winds, and are therefore under an atmosphere with a uniformly eastern progression as a part of the general system of atmospheric circulation of the globe. The local use of the name I'rade Wind at San Francisco, and to a less degree in other parts of the State, must be commented npon to prevent misapprehension. By common usage the term has been erroneously applied to the strong northwest winds, of that vicinity; in connection with the general system these winds are Passage Winds and will be examined as such; the local usage is here mentioned in order that it may be clearly stated that it is not followed. These Passage Winds have a clear sweep across many thousands of miles of sea, and in all this course they incur no resistance save such as is caused by convective friction due to varying amounts of pressure within their mass. But the ntoment they cease to flow over the sea and begin their course over the continental mass they are subject to violent perturbations, and present all the features of turbnlent motion, its irregular and rapid changes of pressure, its rapid expansion, its sudden alterations of the saturation constants, and variations of temperature. These perturbations must be examined in the light of mountain influence in general. The wind drawn in from sea by the general circulation of the atmosphere may be taken to have in suspension the maximum amount of moisture, and, other things being equal, to approximate the saturation amount theoretically to be expected in air of a given pressure and at a given temperature. The only influences which will tend to vary these amounts are due to variations in pressure and temperature caused by possibly distant commotions of the atmospheric envelope. Advancing npon the land the air current immediately encounters perturbing influences of many' sorts, of which these may be mentioned: Friction upon uneven surfaces, convection caused by radiation from irregularly heated bodies, and vortex motion within the stream, these being influences at work no matter what the inclination of the surface ; of perturbations due to planes which are at a considerable angle with the horizon, there are these in addition the development of pressure by transformation of the impact of the air current upon the elevating plane, the loss of temperature by elevation, the alteration of pressure, and the expansion due to the same cause, and the great diminu- tion in 'the amount of water which may be held suspended. There is further to be taken into the count the variation of the character and amount of the mountain fnfluence due to alterations in its radi ation of heat. This variation is seasonal and follows upon the astronomical change of seasons at a greater or less interval as conditioned by local -circumstances of environment. In brief 'it may thus be expressed: When snow clad, and so long as the snow area maintains a superficial extent great enough to aflect the air passing over it, the mountain presents its minimum influence of perturbation because the snow is most activelyemployedinreflectingtheincidentray of solar heat which in its reflex as in its direct passage exerts little effect upon the highly diathermanous air, because the snow has but slight absorptive power and its conductivity is so small that .the mountain is stripped of all the radiating influence which without the presence of this screen would be actively exerted. The air body thrust from behind is forced up the slope, everywhere assuming the conditions normal to the elevation, the isobar and the isotherm in which it is found; at the summit the resisting and transforming influence is withdrawn, the vertical component in its motion ig H. Ex. 287 22 338 IREIGATIOK AKD WATER STORAGE IN THE ARID REGK^KS. lost ; the horizontal component regains its foil value, and the air moves off in its proper direction at the height to which it may have been thrust and communicates its motion to the strata below by the constant intercirculation of contiguous air spaces. The disturbances are all at their minimum, and so is the precipitation. But when the snow cap has melted away another set of influences comes into operation. The mountain then exposes its utmost absorbent surface, and in consequence becomes a highly active radiating agent. The moving current of air which passed over the surface of snow with the least amount of irregularity is now involved in a series of convective foci, the regular imposition of its strata is completely upset, it is suddenly drawn to great heights by these violent updrafts, and its excess of moisture is condensed by the rapid expansion. The period at which this action sets in upon the Sierra Nevada is dependent upon the monthly march of the isotherms under'the inovement of the sun from north to south. The length of time during which it may continue is modified by local conditions which would need individual examination. So far the attention has been directed to the passage of the air current over the ridges. That is not the only direction in which its activity is manifested. A column of ^ir movinpr horizontally against a vertical barrier would be fairly resolved into two components moving respectively to the right and left along the face of the barrier. Incline the barrier in the direction of the motion and a portion of the column would pass over, the amount of this passage and its ratio to the horizontally perpendicular currents being greater in proportion to the inclination away from the vertical. This case is presented by the Sierras; part of the wind goes over, part goes south, and part goes north. Thus alone can the circulatory system of the Great Valley be satisfactorily explained. Two elements in the turbulent motion of the progressive air flow condition precipitation, not so much in amount as in position. Impact with an eleva,ting plane produces in the air stream an extensive system of eddy whirls and vortex motions, which induce a circulatory system within the mass. The moisture just at the pressure and tempera- ture point of precipitation is then subject to a distributive influence, which diffuses it for a greater or less distance from the condensing mountain range and causes it to appear as a windward rainfall. Similarly, of a rain to leeward of the condensing heights, the amount is determined by the altitude of the ridge, and decreases in the ratio of the altitude. The effective operating causes in this case are two. The first is, that,on the weather side of a high mountain range the moisture is largely precipitated before the elevation of the summit is reached, and thus there is absolutely little left to drift over on the leeward side. The second is, that the small amount of rain which is condensed at alti- tudes sufficiently high to allow it to drift past the condensing summit is subjected to influences which have a tendency to still further reduce its amount, as it falls into vertical isobars and isotherms, which condition a higher dew-point and a decreased precipitation. ^ These considerations have been presented as general principles. Before advancing to a discussion of their specific and local appearance upon the region under review, it will be necessary to examine in a similar way the principles which hold upon the sea. Having examined the factors of discharge of moisture, some study should be given to the sources whence that moisture is drawn into the air. The Pelagic influence. — Regarded broadly as a portion of the general atmospheric circulation of the globe, the Passage Winds may be held to be practically desiccated at the ^ime when they appear as surface winds. Their former course has been in the extreme upper regions of the atmospherb, in ruling conditions of excessive cold and tenuity, which have served to remove almost their last humidity. Drawn suddenly to the surface at about the thirtieth parallel, they are in marked contrast with the sea. The sea is warm and inthe best condition for giving off moisture, the wind is most receptive, and the amount of humidity which it will assume is mainly conditioned by the dist/ince through which it passes over water surface. In the regions where the wind prevails with southwestern inclination this distance may be easily determined, and will serve as a means of comparing the average amount of moisture received by places on the Pacific coast. The formula to be applied is this : The distance traversed by the wind is equal to the square root of twice the square of the difference of latitude of the place measured from 30 degrees. This is based upon the theoretical consideration that a dry wind will assume a certain proportion of moisture from every mile of water surface traversed. It must be used with caution, for although it may be proved to be of general'appli- cation, it is subject, like all general principles, to the modifying influence of local and temporary conditions which may avail to override it. Yet, from examination of the annual precipitation chart of the region, it maybe shown that this influence does exist and does exert a considerable activity in govern'ng the amount of rainfall. In this examin- ation it should be said that any annual chart tends to obliterate all local and temporary conditions and to strongly characterize all features which are general and secular. In the following table the results of such a general examination are presented. In the first column the position of five (yitioal stations is given to the nearest degree of latitude, and disregarding the difference of longitude which would be subtractive in influence. The second column shows the length of water surface traversed by the southwest wind, computed from the formula above presented. The third coin mik is obtained by using the least distance in the second column as a unit and computing the values of the other distances relative to it. The column of measured rainfall is taken from the records of the Signal Service. To obtain the values of the theoretical rainfall the minimum precipitation of the observed series has been assumed as the unit of water tarried by the wind, and from this unit the other values have been computed by maltiplication with the factors in the second column. The differences are noted immediately following: IRKIGATION AND WATEE STORAGE IN THE ARID REGIONS. 539 Humid constitution, Passage Wind, North Pacific. Station, Traverse, Per centage.

These stations are all upon a section of the coast line which has many natural peculiarities to distinguish it from the tread below Cape Meudocino. The column of differences shows that while this theory of the humid constitution of the southwest wind may account for a certain portion of the rainfall, there yet remains another portion for which other causes must be sought. The differences themselves show some relation to one another and prove the increment to be progressive with increased northing in latitude. Examine the functions of these differences and this appears distinctly. The drfiereuoe of the differences Westport-Columbia Bar is 9.33, and the difference of the differences Columbia Bar-TatoosU is 19.76. The northern function is twice the southern. It becomes a matter of more than mere curiosity to discover what humid influence has such an increment northerly. Here is painfully felt the lack of data, for the oceanography of the Pacific has yet to be writtdu, and even the materials are scanty. But one thing is certainly know^, because universally observed, and that is, that within the zone of the Passage Winds across the great ocean the wind hauls ' westerly in close ratio to the latitude. The wind which moves the rain upon the northern Pacific coast is then not rigidly a southwest wind. It blows from nearer west, traverses more water, absorbs more moisture, and precipitates more rain, and this proves a factor of progressive increment to the north arid capable of producing an influence of perturbation such as has been beautifully revealed in the functions of the differences in this inquiry. *> Evaporation. — This element introduces a most important factor in the examination of the availability of water precipitated as rain or snow, and at the outset it may be said that this influence attains a great intensity within these limits, and in fact that one of the two culm inating points of evaporation is found in the sink of Owen's Lake where the annual amount exceeds 100 inches. * Two systematic series of observations have been conducted within this region. One will be found discussed in the Signal Service Monthl y Weather Review for September, 1888. The instrument used in securing these records was an evaporometer of the Pioh6 pattern, and the observations were conducted from July, 1887, to June, 1888, inclusive. The records of the ten stations which determine this element for California and ITevada are here presented : Stations. Jan. Feb. Mar. Apr. May. June. July. Aug. Sept. Oct. Nov. Deo.

The curve of 100 inches is drawn with close agreement to the floor of the valley of Owen's Lake. The curve of 100 inches on the strength of observations at Keeler and Yuma is drawn as a narrow loop entering California at Yuma, running along the eastern base of the Sierra Nevada until just north of Owen's Lake it recurves southeastward over the 3,000-foot plateau in Nevada and enters Arizona a little north of Mojave. The 90-inch curve is given a course very closely parallel to this, bur at its northern limb is narrowly projected upon the 3 000-foot plateau of Nevada. The 80-inoh curve follows the high line »f the Sierras, includes Winnemucca, and returns over the White Pine country in Nevada. The curve of 70 inches is drawn along the southeastern deserts and the western flanks of the Sierra Nevada swinging northeastward from Red Bluff and beyond the northern boundary into eastern Oregon, The 60-inoh and 50-inch curves are drawn upon the southern coast ranges and the extreme length of the great valley, whence they pass northeast. The 40-inoh curve follows the coast ranges and parallels the coast line. The other series of observations was conducted by the State engineer of California at various points in the San Joaquin Valley, 7 stations in all. The method employed was to measure the actual amount of water /which evaporated from pans in close proximity to the wafer or land surface. On this account the two systems of observations are not conformable and no co.nparison can be attempted. These latter records may be found in William Ham Hall's Physical Data and Statistics of California, 340 lEEIGATION AND WATER STOEAGE IN THE AEID REGIONS. CLIMATE AKD WEATHER. There have now been piesented the two great aupeTficial factors of the California climate and an explanation has been given of the general principles most prominently displayed in the activity of each factor. The mechanical resultant of these two influences under higher determining conditions is the climate of California and Nevada, a climate which differs from that of any district within this country, and which, practically constant as a whole, displays equally constant dififerenoes between the several natural districts into which the region is divided. Yet before proceeding to the investigation of the several districts and the study of how the influences at worlt therein are combined in varying proportions, it may be well not to lose sight of the fact that the region has a distinctive climate as a whole, and on this account it will be advi sable to present a general review of the climatic characteristics which dominate the whole region. Thedistinguishingcharaoteristicoftheclimateof the region is that varieties of weather endure practically unaltered for days at a time, and even when supplanted by others return again and again, and on each such recurrence are sym- metrical with their former appearance even when tliey are not practically identical. In this regard there is a wide variation^om the conditions which obtain elsewhere in the United "States. Nor is this the only difference. Another notable one is that the storms of the Pacific are witli comparative infrequency traced across into the Central valley and the Atlantic slopes. Another is that storm frequency increases rapidly toward the north. When the area of low barometer of considerable depth overlies Oregon and Washington and probably is central far to seaward, and the cyclonic type appears, its translation east ward is checked if not prohibited by the barrier of the Cascade Range and the Rocky Mountains which here begin to fuse. Held back by the mountain wall and the equally potent barrier of high pressure eastward the low is kept beating against these obstacles and the high remains steadfast over the Great Basin and the Northern Plateau. While this condition endures gales are felt upon: the Cali- fornian coast as far down as Cape Mendocino and the rain occurs in the Great Valley and down the coast to San Luis ' Obispo. These storms leave the southern part of the State untouched except when a subsidiary low is developed over the Colorado Desert when the brief "Sonera storms" occur. When this low area is shallower and can be plainly seen to have its center not far out upon the sea but over Wash- ington, and the high is plainly marked upon the Great Basin, then occur light showers from San Francisco northward, with strong gales at Cape Mendocino, the temperature over the dry area is usually high and occasionally of steep gradients and In the Los Angeles region the warm Sai^ta Ana winds occur. The rain rarely passes south of San Fran- cisco except in cases where the deflnition of the high is so strong toward the south of the Great Basin as to condition a low advancing over the Southern Coast Ranges and back of the Sierras to meet it, then light showers may occur between San Luis Obispo and San Diego. TlAse two oases have presented the conditions of low pressure over Washiugtou and Oregon accompanied by rains which for the most -part occur in California only iu the region north of the southern inosculation of the Coast Range and the Sierra Nevada. When on the other hand a high area rests upon the two northern States and the low type is permanent over Southern California it conditions for California a climatic manifestatijn of extremely unstable equi- librium and while this arrangement of the meteoric elements is of frequent occurrence it is often of short duration. When the low is in the north rain falls upon Califor nia, when the high is in the north fair weather is a marked con- commitant. During the perfection and greatest intensity iu the prevalence of this arrangement and while the isobars are per- pendicular to the general trend of the coast line and the axial inflection of the Coast Ranges and the Sierra Nevada the Great Valley is exposed to "northers" marked with disastrous desiccating influences. The day temperature is ' usually high, increasing proportionally to the duration of this climatic type, but at night frosts are of characteristically frequent occurrence. The winds increase toward the south, being light and variable on the Oregon coast but high gales on the Californian coast. When this type occurs in spring and is acoompauied in Southern California by high winds and sandstorms rain is almost certain to follow. In general the breaking up of this type is heralded by frosts of more or less severity. The most severe and general rains of the region occur in co-ordination with a general climatic disturbance over the whole country. To the eastward there is a series of waves of abnormally high pressure over the eastern guiding planes of the Cordilleran system reaching thence across the Central Valley an I the Appalachian system to the Atlantic seaboard and everywhere accompanied by severe storms and intense cold. Upon the Pacific coast in correlation with this eastern disorder the barometer drops very low and exhibits rapid fluctuations with remarkable gradients between the coast and the interior, the rain area overspreads all sections, gales are marked with the greatest violence the rivers attain their high levels and tend to floods; in general the condition is.thatof an extensive cyclonic disturbance which, proving unable to scale the Sierra Nevada, is forced to spread out over the entire length of the coast region until it gradually wears out with the restoration of climatic equilibrium beyond the range, or if it does move east- ward does so at some extreme point beyond the sphere of observation. In this condition of the weather the rain is precipitated with practical impartiality from SisKiyou to San Diego. Another rainy condition is found when^ diffuse and moderate high exists upon the southwestern coast accom- panied by unusually low temperature and apparently unaffected either by the presence or the absence of a faint and shallo* low on the northern coast. With this arrangement of climatic factors the isobars are somewhat perpen- dicnlar to the coast, a condition almost certain to bring rain, while if these carves of pressure assume a parallelism with the coast line fair weather soon follows. Daring the prevalence of this condition there are rains upon the Los Angeles country and the Great Valley, and the winds above San FraacUco are feeble, except iu the rare instances IRRIGATION AND WATER STORAGE IN THE ARID REGIONS. 841 where tlie barometer sinks excessively. Should the absolute general pressure fall considerably below the normal, yet retaining the relative high upon the southwestern coast, gales rage in southern California, with occasional storms of thunder and hail. This condition determines very suddenly by the movement of the high up the coast and its obliteration as a distinct feature in its progress. A condition which leads to rains of local character, yet impartially distributed as to occurrence within geograph- ical limits, is marked by a moderate low continued through a succession of days and below the normal over a large area. The isobars are then diffusely d isrnpted ; they arfe wavy or inclose several subsidiary lows, occurring over mountain basins with a marked absence of any decided gradients. The winds are variable, the temperature declines, the sky is cloudy, rain comes at intervals, rising under favoring conditions to a gale, which while quite local in^har- acter sometimes does considerable damage within its narrow limits. The dry season shows little variation from beginni ng to end. Bain is almost entirely absent, and the light show- ers which sometimes occur on the Washington coast only rarely drop dpwn upon a limited district of the Californian shore. Another feature of the seasoli is the development and persistence of marked intensity of the high in Oregon, accompanied with a correspon d ing fixity of a slight low area over southern California, creating the characteristic northerly winds which blo'w do wn the Great Valley. Yearly precipitation. — At this point it will be well to examine the chart of annual precipitation upon the two States, California and Nevada, and to discuss its tracings as the general average of the results of the climatic forces before noted and as exercised over wide areas. In the examination and review of the monthly charts it will be more pertinent to discuss the rainfall by natural districts of the region in each of which these constant forces are subject to various local modifiers which widely yet consistently differentiate the results and with even greater promi- nence are ruled by barometric constants of the month, which, it will be necessary to figure over the greater portion of the continent before it can be made clear how the correlation and configuration of the atmospheric mountains and valleys govern the climate of the Pacific coast. The annual rainfall upon this region may not be dismissed with a few general terms ; it offers too many peculiar problems to be lightly considered. On one hand it includes one of the earth's regions of absolute minimum, and on the other it projects far into the region of the greatest precipitation of this country. Nevada, uniform in topog- raphy, displays a similar uniformity in its precipitation features. California, of rugged profile, is equally irregular in its rainfall. To follow satisfactorily the distribution of the rain it is necessary to revert to the. physical outlines of the country and to hold in mind the precipitating influence of mountain masses. The State of Nevada lies entirely below the curve of ao inches annual rainfall. This curve will therefore form a convenient base line to which to refer all other districts for determination of their relative character as arid or watered. It appears upon the heights of the Southern Coast Bange, upon the highlands of the Coast Ranges south of San Francisco, branching from the southward to include east and west, the Salinas Yalley, upon the foothills of the Sierras on the eastern side of the Great Valley, and similarly on the lower hills which westerly bound the valley of the Sacramento it passes out of the land at San Francisco. Below this line is arid California, which at the same time is wonderfully rich in all operations of husbandry ; above it is a laud which while better watered is less available for agriculture. As shown on the annual chart the arid region m^be noted in a few general areas, the Great Valley, the Salinas Valley, the Southern Coast, the Colorado Desert, and Nevada. The regions of higher precipitation are with considerable precision regions of greater elevation ; the greater rainfalls upon extensive summits wherever found, "■ upon the Sierra Nevada, and in a scale of rapid increase with latitude upon the northern coast. The attention will first be directed to the curves which lie upon the arid region, because it is there that irrigation must be applied, if anywhere, and because the watered region, for the most part unavailable for agricul|iaral purposes, must supply that water of irrigsition. The onrve of least rainfall is the curve of 3 inches, which is drawn in a narrow tongue in the extreme southeast of California on that noteworthy valley of the desert whose floor is below the level of the sea. The curve of 5 inches closely follows this curve of least precipitation until it nearly reaches the Colorado Biver on its eastern limb, then sharply recurving upon itself it reenters the desert to include Daggett and Fort Cady and bends back to the Colorado River below Needles. A second area of 5 inphes, not as yet definitely connected with the former though such a connection is indicated, begins upon the desert west of Daggett and narrowly extends northward with definite persistence upon the plateau of 3,000 feet elevation, which forms a characteristic trough in western Nevada and extends far enough to include CarsoU and Humboldt Lakes. ANsusp of the curve of the same weight in the northern Bonneville Valley of the Great Salt Lake enters the Territory for a short distance in the northeast of Nevada at Tecoma. The same system governs the arc of a 10-inoh curve which outs off the northeast corner of the State. The general Great Basin 10-inoh curve enters the region from the eastward between the thirty-seventh and thirty- eighth parallels, closely aligns itself upon the brink of the 5,000-foot plateau to the intersection of the forty-first par- allel and the one ^hundred and fifteenth meridian ; thence westerly along the northern rim of the Lahontan Basin, beyond Pyramid Lake, it advances upon the eastern face of the Sierra Nevada, which it follows southerly to its decline, and then, similarly placed upon the eastern face of the Southern Coast Bange at the edge of the Colorado Desert) it passes from the Territory and into Baja California. The greater part of the floor of the valley of the San Joaquin, the southern moiety of the Great Valley, is in receipt of less than 10 inches.' The limiting curve has a wide sweep along the foothills in all that part of the valley included in the counties of Tulare and Kern ; north of Tulare Lake it appears as a strip lying quite east of the river, with its eastern limit just inclosing Visalia, Goshen, Kingsburgji, Selma, Fresno, atfd Firebaugh's Ferry, recurving at Los BaHos. The other appearances of this curve upon the region, though well defined, are unimportant by reason af the small area included. These are a narrow seacoast atrip from 342 lEEIGATION AND WATER STOUAGE IN I'HE AlllD UEGlONS. Tia Jaana to the PenascinUas Creek, including San Diego; the upper valley of the Santa Ana as determined by the records of CoUon and Kiverside; and a scanty strip south of the sloughs of the meeting San Joaquin and Sacramento Kivers, determined by the record at Tracy. In eastern Nevada a narrow loop of 15 inches clings to the north and south valleys of the White Pine Ranges from Pioche to Fort Halleck. Tlie general 15-inch curve of the Great Basin enters upon the northern border 3,t Fort MoDermit, sweeps eastward to include Tuscarora, and then swinging sharply back along the upper edge of the Lahontan Basin parallels the 10-inch curve of the same system upon the eastern Sierra face as far as the heights ■which break away above the Tehaehapl Pass. Here, crossing the decadent Sierra Nevada, it enters upon the Great Valtey and rapidly seeks the lower contours and comes out upon the level floor of the valley in Fresno County. Thence northward it is the dominating curve of the counties of Merced, Stanislaus, and San Joaquin. Curving westward, a little west of Gait, it incloses the sloughs of Sacramento, Solano, and Contra Costa Counties, and then trails off south- erly along the western level of the San Joaquin Valley and begins to climb the slopes at a point west of Tulare Lake, and thus by gradual steps marks the western as well as the eastern wall of tHb Tehachapi Pass, leaving the inter- vening breach a. passageway through which tlie San Joaquin dryness unites with the desiccation of the Colorado Desert. From the Tehachapi Pass southward this curve is marked upon the eastern face of the Southern Coast Ranges and with many involutions follows their direction out into peninsular California. The 15-inch curve of the southern coast system appears from the south along the western 1,000-foot contour of the ranges to the valley of the Santa Ana River, wljere it sweeps around the 10-inch area already drawn there and thence follows the coast to Point Conception. Other appearances of this curve are about the valleys of the Salinas and San Benito and on the floor of the Sacramento Valley, in Colusa and Glenn Counties. The '20-inch curve has already been broadly outlined as the mark of separation between arid and watered lands. The only addition to its course as there noted is a cusp of the area which appears on the northern line of California, and opens toward the arid lands of eastern Oregon. The curve of 25 inches crosses the northern boundary of California somewhat west of the middle point. Thence easterly and soutlieasterly over the counties of Siskiyou, Shasta, Lassen, and Plumas it assumes a position near the crest of the Sierras closely paralleling the 20-inch curve as far as the headwaters of the Kern River. Here it returns northward upon the foothills of the Sierra, gradually seeking lower levels as it advances up the Great Valley to in- clude Red Bluff, whence it returns upon the western wall southerly until it leaves the region through the Golden Gate after having encircled tlje Sonoma Valley. Disconnected systems of this curve appear as follows: inclosed within areas of higher precipitation, a small 35-inch loop at Ukiah and the Upper Russian River Included in a 30-inch area; overlaid Upon areas of lower preoipit5.tion, on the Southern Coast Range in the vicinity of
