Our task is to set forth its discovery, settlement, geograptiical location, topographical features, geology, climate, soils, minerals, rivers, agricultural advantages and productiveness, its commer- cial opportunities, educational facilities, development, progress and the excellence of its intellectual, social and moral life. The subject is broad yet inviting, the duty is a pleasant one, yet in many respects one difficult of accomplishment. The artist who would attempt to present with the brush the grandeur of hue and majestic form of the bow of promise would find the task to lie beyond the reach of his culture or the grasp of his endow- ments. So the pen is inadequate to present in its bright and winsome reality this realm of topographical beauty, rich resources, gracious climate and excellent development which earth's millions now know as the State of Iowa. THE NAflE, IOWA. Prior to the settlement of the region a tribe of the aboriginal inhabi- tants were designated by a term from which we have the name of Iowa. An intelligent and early pioneer of the territory now forming the state, well acquainted with its native tribes and their languages, Mr. Antoine Le Claire, stated that this word, used by its original inhabitants to designate the portion of the country which they occupied, signified "This is the land." Pre-eminently among its sister states Iowa is "the land." DISCOVERY. Iowa was first seen by white men in the summer of 1673, two hundred and twenty years ago. The French settlers then occupying Lower Canada, in exploring the great lakes and their connections, had reached Mackinaw, and the Catholic church had formed at that place a missionary settlement. In their association with the Indians its missionaries heard of a great river in the west that came out of the north and flowed into the far-away south, and a wonderful land along its shores. So enrapturing were the descrip- tions given of the "Father of Waters" and the beauties of the treeless land bordering it, that an educated missionarj% then laboring at Mackinaw for the conversion of the Indians, became possessed of an intense desire to explore it. Louis Joliet, a young man of Canadian birth, but of French descent, well educated, active and ambitious, traveling under the authority of the government of Quebec, reached Mackinaw in one of his adventurous voyages of exploration. There he met Jacques Marquette, an educated missionary priest. These two energetic men with five French-Canadian attendants, left Mackinaw on the thirteenth day of May, 1673, in two bark 2 HAND BOOK OF IOWA. canoes to reach, if possible, the great river of which they had heard, and explore "the beautiful land." Father Marquette and his companion, Joliet, were both intent on enlarging the dominion of the French government, but the former was more directly concerned in propagating the Catholic faith among the native tribes in the then unknown interior region of this then unknown west. Leaving Mackinaw in their two canoes, frail vessels for such a voyage, with "some Indian corn and some dried meats as their stock of provisions," these intrepid Christian leaders coasted along the western shores of Lake Michigan into Green Bay, On reaching the mouth of the Fox River they entered it and ascended to the portage, where, being- directed by Indian guides, they transferred their canoes and provisions to the Wisconsin river and descended the stream. On the seventeenth day of June when near its mouth they looked across a greater stream", the "Missi," great, and "Sepe", river, on the western shore of which rose the high bluff on which, in 1805, Lieut. Pike planted the United States flag. Then had they the first view ever enjoyed by white men of the strange land on the sunset side of the great river which their venturous voyage was made to discover. Of the thoughts and emotions of those men, forming that day the vanguard of our present Christian civilization in this central west, we have no record. Something of the strange musings they indulged as they rode in their fragile vessels amidst their strange, weird surroundings, we are left to imagine. Gliding slowly down the great stream on that June day, the valley and the not far away hills that bound it were clothed in summer luxuriance. As they entered the Mississippi to their right, but little above them on the Wisconsin shore lay a beautiful prairie, reaching miles up the great stream and some three miles back from the river, but this they did not see. In front of them on the Iowa side of the larger river were the high bluffs, but turning down the stream they were soon in a delightful river archipelago. The first Iowa prairie they beheld was that on which the town of Guttenburg was built. In all this varying scenery they saw no sign of human form or habitation. It is said they rode on the river four days before the first sign of human inhabitant was seen. Then they beheld human footprints in the sand. How profound the solitude in which they rode ! How wonderfully different that great valley now from its condition, then ! Those men must have been conscious that they were in a vast in- habitable region, but had but slight conception of its present wonderful development and civilization, more beneficent than any which in their day shed blessings upon humanity; which in this celebrative year graces with its wealth of happiness the dwellers in the great central region which they then discovered, but now having w^orld-wide fame alike for its beauty and its productiveness. In this commemorative year which calls the millions of the na- tion to the shores of the great lake, from which those men began their voyage, should any of these millions traverse this interior region^they will find on the shores of the great river then discovered, ten Christian com- monwealths, all free, powerful states, yet parts of this one powerful Nation- ality. Those ten states have a population of nineteen millions"of Christian THE SETTLEiWENT OF IOWA. 3 people, and possess a wealth surpassinir the riches of the wealthiest nation of as recent date as Iowa's discovery; while on that tree-clad, western shore on which those men first looked with inquiring anxiet}', there is now this beautiful state, the home of tw'o millions of the most prosperous, intelligent orderlj' and happy people of earth. In the intervening years, this reo-ion then nameless to those adventurous voyagers, largely covering the fertile peninsula formed by the two largest rivers of the country, then an unex- plored, herbage-covered land, inhabited only sparsely by an uncultured savage race, has made a progress in civilized attainment that must ever be the marvel of the country's history. Here are now commercial facilities manufacturing forces, educational advantages, and a Christian freedom and liberality unknown to the world when this beautiful portion of the country was discovered. THE SETTLEMENT OF IOWA. The territory bordering the Mississippi river extending eastward of that stream to the Alleghanies and westward to the Rocky Mountains, and from the Gulf by which, thrives the stately palm and fragrant orange, to the great lakes, was bj^ right of discovery subject to the crown of France. In the course of human events that portion of this interior territory west of the Mississippi and reaching from Lake Superior to the Gulf of Mexico passed under the dominion of the Spanish crown. In 1800 Spain receded this great territory to the French government. That part of the original French possessions in this region lying north of the Ohio and east of the Mississippi had, by the conquest of Canada, become subject to the British crow^n, and by the fortunes of war in the American ReVolution had subsequentlv be- come United States territory. In 1803, by the treaty arrangement known as the Louisiana Purchase, France ceded its possessions along the Missis- sippi river to the United States government. The wise action of the Jeffer- son administration in extending the western frontier of the country to the Rocky Mountains, secured to this fertile prairie-interior the advantao-es forever, of free government and liberal laws. When the Revolutionary war closed settlements soon began to extend w^est of the Alleghanies from New York, Pennsylvania, Virginia and the New England states. In 1802 Ohio was admitted into the Union. In 1730 the French had formed a settlement at Vincennes and in 1809 Indiana was given state government. Yet in 1810 its population numbered only 23,890 white persons. In 1720 the French had formed a settlement at Kaskaskia. In 1818, lacking but two years of a century thereafter, Illinois was given a place as a state in the Union. Yet in the centennial anniversary year of the founding of that settlement at Kaskaskia that state con- tained a population of only 53,788 white persons. A French settlement was formed at Detroit, ^lichigan, in 1701 but the census of 1830, taken 129 years thereafter, reported the population of the ^Michigan territory at only 31,346. Several more years passed before the American Congress gave it statehood. At the close of the first third of the present century the population of the four states formed out of the old Northwestern Territory covering the region between the Ohio river, the Mississippi and the Great Lakes had a 4 HAND BOOK OF IOWA. population only a little in excess of one and a half millions of white per- sons. In 1870, forty-three years after the permanent settlement of Iowa began, it had a larger population than Michigan, the settlement of which was commenced a century and a half before the first settlement was founded in Iowa. For 113 years after the discovery of Iowa by Joliet and Marquette it remained virtually an unknown land. In that cycle of slow transportation, limited reading, but numerous discoveries of new lands, the discovery, of this interior portion of the North American continent had failed to attract public attention. No effort was made to effect any settlement within the borders of what is now the state of Iowa, until the fall of 1788. Julien Du- buque, an adventurous French trader, having secured from the Indians a grant of land extending southwardly from the Little Maquoketa river seven leagues along the Mississippi by three leagues inland, embracing about 121,000 acres, formed a settlement thereon. On it, it is said Dubuque "improved an extensive farm, built houses to dwell in, erected a horse mill, cultivated the farm and mined lead." lie died in 1810 and his possessions w^ere soon controlled by others. The Indians became dissatisfied with the lead mining and other conduct of their French and half breed neighbors, drove them from their mines and homes, and broke up the settlement. In March 1799 Louis Honori obtained a grant of land from the gov- ernment of Upper Louisiana in Lee county, where the town of Montrose now stands, near the head of the rapids in the Mississippi river. The tract was sold from him in 1803 and a settlement, founded by him, was abandoned. Various venturesome parties of hunters, trappers and Indian traders made temporary settlement along the Mississippi, within the limits of Iowa, from 1820 to 1830, but did not permanently remain. In 1809 a military post had been established on the present site of Ft. Madison. , The troops however did not long occupy the post, its establishment having been in violation of treaty stipulation made with the Indian occupants of the region it was abandoned bv the government. The city of St. Louis was founded in 17G4. It soon had trade with the Indians. In 1804 that city, the river approaches of which were then nayigated by only flat boats and Indian canoes, passed, by the Louisiana Pur- chase, under the dominion of the United States government. Three years later Robert Fulton made his successful trial trip on the Hudson with the "Clermont", and steam, as a motive power on American rivers, was demon- strated to be a practical force, and soon had large application. In 1817 the first steamboat reached St. Louis. That city then passed from its primal stage, as a mere trading post for Indians and hunters, to a growing and im- portant commercial center. Steam navigation being applied on the Ohio and Mississippi brought settlers into southwestern Illinois and northeastern Missouri and prepared the way for the settlement of Iowa. The western border of Iowa was first traced in 1805 by the Lewis and Clark expedition on its famous journey across the continent by way of the Missouri and Columbia rivers. Maj. Pike traced its eastern border as he ascended the Mississippi river to its source about the same time. The re- ports of these expeditions published by the government, with the reports of the journeys of hunters and Indian traders through the territorj", spread BOUNDARIES AND AREA. 5 knowledge of the remarkable beauty and natural excellence of this then far western re»;ion. When the Indians were Anally subdued b}- the defeat of Black Hawk at the "Bad Axe" in 1832, and permanent safety was thereby assured to venturesome pioneers, settlements rapidl}^ formed on the Iowa side of the Mississippi. Xo region, ever opened for settlement, offered more inviting advantages to home seekers, and they were rapidly embraced. In 1833 the area now comprising the state of Iowa was a part of the ter- ritory of Michigan. Its legislature organized two counties within what is now Iowa, naming them Des ^loiues and Dubuque. Three years later, namely in 1836, Congress organized the territory of Wisconsin— Iowa con- stituting a part of that territory. In 1838 the territory of Iowa was consti- tuted b}^ act of Congress, and Robert Lucas of Ohio was appointed to the office of Governor. The first legislature of the Iowa territory assembled November 12th, 1838, at Burlington. Iowa, as a territory, embraced a con- siderable portion of what is now^ the state of Minnesota, and had almost un- limited expansion toward the setting sun. On the opening of Iowa for settlement in 1833 settlers rushed into the lead mining regions surrounding Dubuque, and that city was founded. In 1836, three j^ears after Iowa was opened for settlement, the population of the territory numbered 10,315. Two j'ears later the population had in- creased to 22,850. In the census of 1840, taken but seven years after the territory was opened for settlement, the population numbered 43,112. Six years later a state enumeration found the population to be upward of 100,- 000. The star of empire was taking its way westward, the people of the timber-clad east had heard of the beauty and richness of this prairie laud where a farm could be made in a season with a yoke of oxen and a plow, and were coming in by thousands to enjoy the beauty of its broad landscapes, the glory of its sunshine, the purity of its waters and the fertility of its acres. In 1850, but seventeen j-ears after the building of the first cabin in its permanent settlement, the second national enumeration therein reported a population of 192,214 free men and women. December S, 1846, but thirteen j^ears after its first permanent settlers entered upon its soil, Iowa was admitted into the Union. The fame of its wonderful natural meadows and the beauty and fertility of its prairies had spread, not only over this country, but had crossed the seas and the people of other countries, as well as the states in the east were crowd- ing in to find homes in this richly inviting region of the prairie west. BOUNDARIES AND AREA. The constitution under which Iowa was admitted into the Union fixed the boundaries of the state as follows "Beginning in the middle of the main channel of the Mississippi river at a point due east of the middle of the mouth of the main channel of the Des Moines river, thence up the mid- dle of the main channel of the said Des 3Ioines river, to a point on said river where the northern boundary line of the state of Missouri, as estab- lished by the constitution of that state, adopted .June 12th, 1820 — crosses the said middle of the main channel of the said Des ^loiues river, thence westwardi}' along the said northern boundary line of the state of 3Iissouri 6 HAND BOOK OF IOWA. as established at the time aforesaid, until the extension of said line inter- sects the middle of the main channel of the Missouri river; thence up the middle of the main channel of the said Missouri river to a point opposite the middle of the main channel of the Big Sioux river, intersected by the parallel of forty-three degrees thirty minutes north latitude, (a range of latitude possessing a temperate climate most highlj- favorable for agricul- tural production.) The area of the state covers on the forty-second parallel six ranges of townships east of the fifth P. M., the fourteenth meridan west of Washington and the ninetieth west from Greenwich, and on the same parallel forty-five townships west of that meridan. Estimating each town- ship at six miles the state has an extreme length east and west of 306 miles by a breadth of about 204 miles, including in its breadth thirty- four sur- veyed townships. According to a report made by the Secretary of the Treasury to the United States Senate in March, 1863, it embraces 55,044 square miles, or 35,220,200 acres — an area larger than Scotland, almost as large as England, four times the size of the kingdom of Denmark, five times as large as Belgium; three times as large as the kingdom of Greece, that made the world's pre-Christian historj^ interesting by it glorious deeds and the splendor of its philosophy and architecture; and it is five times the area of the land of Judea, that gave to the world its noblest ethical code, and to the race its Redeemer. Such is the state of Iowa in its location and area; greater than many powerful, wealthy kingdoms in extent, and the equal of great empires in natural resources. The free bestowmeut of the beneficent Creator, its pro- ductive caiDabilities are yet unmeasured, its every acre being fertile. Bar- ren, rock}', sterile, sandy or great swamp areas being unknown in its extent, its ultimate wealth producing power cannot be estimated. GEOGRAPHICAL LOCATION. An artist once represented Columbus as standing and survej-ing the North American continent. When his ej'^es rested upon the brightest spot, central in the vast expanse, that spot was named Iowa. Geographically it is centrally located in this union of states. On the forty-second parallel its eastern boundary is upwards of one thousand miles from the Atlantic's tide by Plymouth Rock, while on the same parallel from its western border to the Pacific's surf-beaten shore, fifteen hundred miles intervene. From the northern line of the state to the British possessions by the Lake of the Woods, the distance is four hundred miles, while between the southern bor- der of the state and the Gulf coast lie the states of Missouri, Arkansas and Louisiana, covering an expanse of 760 miles. A position so central in the richest, freest and most powerful nation of modern times, and central in the vast system of river navigation connected with the great streams that form its eastern and western boundaries, and so situated that the principal lines of railway binding ocean to ocean must cross its territory, must ever possess incalculable advantages in the security its location aifords, the markets it assures, and the commercial advantages that must ever accrue to its citizens. TOPOGRAPHY. 7 TOPOGRAPHY. Iowa is not only princely in its area and highly fortunate in its geo- graphical location, but it is -winsome in its topography. In the days of a geographical ignorance, which an intelligent world remembers now with smiles, Iowa may have been placed in school-book maps in "The Great American Desert." But if this beautiful and fertile state was ever a desert, then surely it was that one of which the Lord's prophet spoke when he de- clared "The wilderness and the solitary place shall be glad for them and the desert shall rejoice and blossom as the rose. ****** ^he glory of Lebanon shall be given unto it and the excellency of Sharon." No grander cedars ever grew on Lebanon than now adorn Iowa homes, and no more beautiful or fragrant roses ever bloomed along the sunny slopes of Sharon than now grow in this realm of Edenic loveliness. One of the more noticeable features of the topography of Iowa is the entire freedom of the state from barren, rocky elevations, or other waste lands. It has no Saharas, dismal swamps, nor fever-breeding everglades. From railroad surveys and other sources of information we have defin- ite knowledge of the elevation of the chief portions of the state. Low water in the Mississippi at the southeastern corner of the state, its lowest point, being 444 feet above sea level. The point recognized as its highest elevation is on the summit divide near Spirit Lake, Dickinson county, it being estimated at 1250 feet above low water at Keokuk, giving the highest point in Iowa an elevation of only 1,694 feet; between these extremes in elevation lies all of Iowa. To show more clearly by comparison the moderate elevations of this area, we notice that its highest point is 165 feet lower than the Union Pacific railroad grade in the Platte valley at Grand Island, Nebraska, the grade at that station being 1,860 feet above tide. The water in the Big Sioux river at the northwestern corner of the state is 1344 feet above the tide level. This is the descent from that point to the Gulf of Mexico via the Missouri and Mississippi rivers. The crest of the state or the summit forming the water shed between the waters of the Mississippi and the Missouri lies diagonally across the state; its general trend being from the northwest to the southeast. Entering Iowa from Minnesota where it separates the waters of the Des Moines and Little Sioux rivers, it leaves the state entering Missouri near the southeast corner of Appanoose county, there separating the waters of the Chariton river from the Fabius creek, having crossed in its course through the state Dickinson, Clay, Buena Vista, Sac, Carroll, Audubon, Guthrie, Adair, Madi- son, Union, Clark, Lucas, Monroe and Appanoose counties. The altitude of this important ridge is shown by the elevations at which it is crossed by the five chief railroad lines crossing the state from east to west. The most southern of these lines is the Chicago, Burlington and Quincy. It touches this great water-shed twice. First at Chariton, Lucas county, at an elevation of 1,080 feet, and the second time at Murray, Clark county, thirty-seven miles west of Chariton at an altitude of 1,268 feet. This line of road reaches its highest altitude in the state at Creston, Union county, 1,355 feet, on the divide separating the Platte and Grand 8 HAND BOOK OF IOWA. rivers, affluents of the Missouri. The Chicago, Rocli Island and Pacific railroad, the next line north of the one first named, crosses^this watershed in the northweetern part of Adair county, at the town of Adair, at an eleva- tion of 1,389 feet. The summit of the divide at this point is fifty feet above the railroad grade. The Chicago and Xorthwestern railroad crosses this watershed at or near Arcadia, in Carroll county, at an elevation of 1,437 feet. The Dubuque and Sioux City (Illinois Central) crosses it at Alta. Buena Vista county, at an altitude of 1,521 feet. Thus the three roads named reach their highest elevations in the state at the crossing of this divide. The Chicago, Milwaukee and St. Paul railway crosses it at or near Ruthven, Palo Alto county, at an elevation of 1,424 feet, but this road reaches its summit elevation at Sanborn, O'Brien county, 1,537 feet above tide, on the divide separating the east and west branches of the Floyd river. The facts here stated show the evenness of the altitude of the summit of the state and that there is a very moderate and easy descent across the state from the northwest to the southeast. From Sanborn to Chariton the descent is 475 feet. The distance is two hundred miles in a direct line, the descent averaging 2.37 feet to the mile. Any map of Iowa will show that the rivers in that part of the state which lies east of the great watershed, trend toward the southeast and flow into Mississippi, and that in the portion lying west of that summit all the rivers flow into the Missouri with a south westernly trend. The traveler crossing Iowa soon discovers that, although a prairie state, and lying under the moderate elevations given, it is not a breadth of swampy levels, but a realm of beautiful undulations, — in some places rising from the streams somewhat abruptly but seldom precipitously. The divides separating the numerous streams generally rising to an altitude of 175 to 250 feet, afford a constant succession of changing scenery. No country affords more graceful land- scapes, when clothed in summer's green or when its groves are dyed in their autumn robes of silver, scarlet, gold and purple. Iowa landscapes are grandly beautiful, and the traveler sees a breadth of farm homes beautiful in situation and surroundings. The great fields of growing grain, in their season, add beauty to the delighting panoramas by every shade of green, covering the broad and billowy areas over which the eye extends. In the summer season great herds and flocks feed amid blooming flowers and rich herbage, and add enchanting variety to the inviting picture. In that season the enriching, life-giving sunshine paints the floral gemmed-meadows with a brilliancy of hue that makes the broad landscapes over which the vision reaches, constantly discovering new charms, superbly winsome. Para- phrasing the language of inspiration we may truly say, "beautiful for situa- ion, and the joy of her people" is beautiful, fertile Iowa. RIVERS. Iowa is a realm of beautiful, perennial streams flowing in deep chan- nels and with rapid current. Prof. White in the first volume of his report on the geology of the state, tabulates the descent of the principal rivers of the state according to railroad surveys and other sources of information which we here copy.

From this table it will be seen that the rivers of Iowa are not sluggish^ stagnant streams. The Little Sioux has rapid fall from its source in the lakes in Dickinson county, on the summit divide, to Smithland. The streanii furnishes many water powers in its course through Clay and other counties^ Below Smithland it strikes the broad flood-plain of the Missouri, and so its small descent below that town is explained. The Skunk is perhaps the flattest stream in the state, yet it flows witk a strong current in its labyrinth of bends through the broad flood-plain ia which its channel is cut. The traveler who had to cross this river in early- days will never forget the "Skunk bottoms." But now with graded and bridged roads, its wide bottom lands are grand pastures and wealth produc- ing properties. Lying in the peninsula bounded by the rivers forming its east- ern and western boundaries, Iowa is not situated to afford inter- ior navigable streams. Its largest interior river, the Des Moines, hast its source in Minnesota, and flows with a southeasterly trend east of the great watershed and empties its volume into the ]Mississippi at the south- east corner of the state. From Fort Dodge to Ottumwa, a distance in a direct line of 150 miles, its descent of two and a half feet per mile gives it a rapid current precluding any great value as a navigable stream but render- ing it of great value for manufacturing purposes. At Bonaparte, Ottumwa^ Des Moines and other places it is made to furnish important water power. Before the advent of railroads, steamboats plied on this river in the spring: and early summer, an occasional small boat running up as far as Fort Dodge. Steam boats occasionally, in those days, plowed their way up the Iowa and 10 HAND BOOK O^ IOWA. Cedar rivers, but the advent of railroad facilities rendered those streams unnecessary for navigation and they have been given up to manufacturing pur- poses. Many of the rivers of Iowa and their affluents furnish numerous and valuable water powers. Some are improved for grist and other mill pur- poses, but many of the most valuable yet invite improvement. The Cedar furnishes water power of great value at Cedar Falls where the river de- scends about twenty-two feet in three-quarters of a mile. At Waterloo and also Cedar Rapids it furnishes important hydraulic power. The Iowa and many other streams also furnish valuable water powers at numerous places. The rivers of Iowa are classed in two systems. The one embracing the streams east of the watershed, the other the streams west of that ridge. The principal streams in the eastern system are the Upper Iowa, Turkey, Ma- quoketa, Wapsipinicon, Cedar, Iowa, Skunk and the Des Moines and its affluents, the principal of which are South, Middle and North rivers, the Raccoon with its branches and the Boone. In the western system we name the Floyd, Rock River, Little Sioux, Maple, Boyer, Nishnabotna, Nodaway, Platte, Grand and the Chariton. These are mostly perennial, manj^ of them serviceable in the milling and manufacturing power afforded. Along their course were many line native groves that attracted early settlers. All flow in fertile valleys bordered by sloping uplands and are sources of pleasure •as well as utility and add beauty by giving variety to the luxuriant land- scapes through their course. LAKES. The people of Iowa do not boast of the magnitude of their lakes nor ■the surrounding grandeur of their "unsalted seas." Yet there are numbers of lakes with charming surroundings, several of which are becoming famous as places of resort for rest and pleasure. Iowa's lakes all lie in the central third of the northern half of the state, and its most elevated portion, where the watersheds are developed into broad table lands. None of her lakes are of value in aiding commerce by furnishing important water transportation. In the sporting season they are inviting to sportsmen, as they are visited by immense numbers of migrating waterfowls, as geese, ducks, brants, swans, pelicans, cranes, etc., and furnish large quantities of fine fish, it being true of them in this particular that "The waters brought forth abundantly." The lakes are mostly bodies of clear, pure water. On the shores of many of them are beautiful groves of native timber, located in breadths of charming scenery and are specially inviting to rest seekers and those desiring health- giving recreation. Clear Lake, in Cerro Gordo county, is about five miles in length by two in breadth. Rice Lake, Silver Lake and Bright's Lake in Worth county are small bodies of water from one to two miles long, Rice Lake lying partly in Winnebago county. Crystal Lake, Eagle Lake, Wood Lake, Lake Edwards and Twin Lakes are in Hancock county. Eagle Lake being the largest of the three. Lake Gertrude, Elm Lake, and Wall Lake, beautiful bodies of water, lie in Wright county, the largest of the three Wall Lake, being about three miles long by two broad. Twin Lakes in •Calhoun county are becoming a noted resort for fishing and pleasure par- ties; the Des Moines and Northwestern R. R. making them easily access- Able. The two cover a length of about four miles. They are separated by LAKES. II a narrow belt of land through which is cut a narrow stream . Some twenty- five miles from these Twin Lakes lies Wall Lake in Sac countj', which is becoming a famous health and pleasure resort. The maps of Iowa show three separate lakes within the state denomi- nated Wall Lake, one lying in Sac county, one (the largest of the three) in Wright county, and one (the smallest of the three) in Hamilton county The idea has been entertained that at some time in the ante-historic period some strange people built veritable stone walls along portions of the shores of these lakes; but that idea is a myth. Over that region in which those lakes lie, when vast icebergs or ponderous glaciers were exerting their mighty forces in forming the wonderful drift coverings of the region, great numbers of boulders were borne by these forces from the north country and deposited about these fresh water bodies. The forces of winter frosts and ice have lifted these boulders in the shallow portions of these lakes and have piled them by their shores. Fancy has conjured them into walls and so they have their name, and thus the stories of the "Walled lakes of Iowa" had their origin. In addition to the above named lakes we notice Swan Lake in Emmet county, which is one of the largest of Iowa lakes. It lies in the central portion of that county and is readily accessible from Estherville, the county seat. It is a beautiful pleasure resort. Storm Lake, one of the most beau- tiful lakes of Iowa, lies in Buena Vista county, on the line of the Illinois Central railroad and by it is the beautiful town of Storm Lake. The largest lakes in Iowa are Spirit Lake and the Okoboji, in Dickinson county. These lie on the great watershed and near the Minnesota line and being accessible ■by the B., C. R. & N. and the C, M. & St. P. railways have become very popular summer resorts. In the winter of 1857 a band of Sioux Indians passed southwardly through northwestern Iowa, and on their return passed through Sac, Chero- kee and Dickinson counties. The winter was a severe one and in the first week of March the ground was covered with deep snow. The Indians had trouble with the few white settlers then dwelling in Sac and Cherokee counties, stealing and destroying the settlers' property. Reaching the Okoboji Lakes they perpetrated a fearful massacre of white settlers who were then dwelling in the surrounding groves. The few families settled in those groves, on account of the inclement weather and the deep snow covering the wide unsettled prairies of north- ern Iowa, were unable to seek protection from the distant settlements, there being no possibility of relief nearer than Fort Dodge, a hundred miles dis- tant. Upwards of forty persons were killed outright by those savages. The settlers' cabins were burned and their property destroyed, and some three or four females were carried ofE as pi:isoners. When the news of the massacre reached Fort Dodge a force was immediately raised to go to the relief of these settlements. The sufferings of that brave band of civilian soldiers were terribly severe. Two of them were frozen to death. The In- dians immediatelj' after the massacre fled into Minnesota and could not be overtaken by the pioneer force. Perhaps the only battle ever fought on Iowa soil between United States troops and Indian warriors took place some thirty miles east of Spirit Lake. 12 HAND BOOK OF IOWA. A company of United States dragoons under command of Captain N. Boone,, about 1842, wliile crossing the state had a skirmish with an Indian band. Iowa has but a brief history of the heroic in Indian wars, or the sorrowful in the massacre of its early settlers by Indian foes. PRAIRIE. Iowa was early linown as a prairie state. Its broad, treeless areas were its glory. Its prairies were not in their natural condition vast marshes, or great breadths of sterile sand, barren of productive power, nor were they regions of cold barren clay. They soon became known as of the finest land, awaiting the plow to turn them into productive farms. On the fourth day after Monsieurs Marquette and Joliet entered the Mississippi they had their first view of an Iowa prairie in its summer dress of green and bloom. This great central region of the country was largely treeless then. How long it had existed thus is only known to Him who created it. Why, how, or when these breadths of fertile acres and beautiful landscapes became treeless, would be useless for us to inquire. Iowa's being so largely prairie favored its rapid settlement. Its first settlers had known something of the toilsome, slow process of making farms with a mattock and an axe in a heavily wooded country. In 1845 a man went into northwestern Ohio, bought an axe and commenced on a piece of timbered land to make a farm. He found it slow work. He after- wards came to Iowa, bought a half section of "raw prairie," went upon it with a breaking plow and team and broke the first furrow made on the tract a mile in length without a rock, grub, tree or stumb to hinder the plow. That was a speedier, saying nothing about its being an easier, way to make a farm. Then there was the continuous advantage of a stumpless field. When he settled in the Ohio woods he could not have cut a ton of hay on a hundred acres of his land; when he came to Iowa he could go out on the prairie with a mowing machine, cut the finest of blue-joint and make all the hay he wanted; as fine as was ever fed a horse. He visited a neigh- bor, an old settler, and going into his hay -yard he asked: "How much hay- have you there Mr. S ?" "I guess about 800 tons," was the reply. Every stem of it made from wild grass. The settler in Iowa soon saw there was a distinction with a difference between making a farm on eastern wooded lands and the prairies of Iowa. Infinite wisdom contrived seven- eights of Iowa's surface to be prairie that Iowa might the more speedily and easily be turned into a paradise. The prairies of Iowa did not invite settlers merely by the ease by which they were turned into fine farm homes,, but the beauty of the views they afforded, the breadth and grandeur of the great natural meadows and pastures they offered, and the ease of communi- cation they provided between neighbors and neighborhoods were potent in- fluences in inducing settlers from the heavily wooded east. The facility of intercourse offered by the Iowa prairie was no mean factor in inviting their rapid settlement. In driving across them there was no climbing over stumps and logs. A few trips indicated a road which was soon worn, if not into a straight, at least into a fine smooth, traveled way. The Iowa farmer had use for a carriage from his first settlement on the prairie. The writer knows something from experience of opening and traveling new PRAIRIE. 13 roads in the east. Talk about the settler there having use for a carriage from its first settlement, he scarcely had use for such a vehicle in the first generation of its settlement. It has been objected that there are terrible blizzards and awful cyclones on these Iowa prairies. "We admit that there are storms in Iowa, but are there no tornadoes, no terrible storms and blizzards in timber covered coimtries? "We know there are tumults in nature's domain in all regions. ]\Ien are helpless before nature's forces in all places, but destructive tor- nadoes in Iowa, like destructive earthquakes in California, are of but rare occarrence. There have been severe winters in Iowa but they have been few in its history. There may have been danger for pioneer settlers in journeying across Iowa prairies from winter blizzards in the past, but those dangers are now matters of history. Iowa winters on Iowa prairies are desirable now for the benefits and pleasures which they afford. The prairies, j^et beautiful, are not now as they were when the pioneer chased over them the agile deer and the fleeing elk. Their great breadths were then open commons with sloughs and streams unbridged. Fire, in the fall, swept off their summer vegetation and left naught to hold in place the falling snow. The settlers' cabins, built in grove or sheltered nook, were far apart. The great breadths of open prairie were houseless and many of the pioneer settlers were poor and thinly clad. Then there was nothing to mark the traveled road in the winter's snow storm, and the traveler seeking to cross the broad prairie may have been in danger when such a storm over- took him, distant from his home or a shelter. But terrible, life-destroying blizzards have been of rare occurrence in our history, while mild, beautiful, healthful winters, giving months of delightful sunshine and the smoothest, possible roads for winter travel, have been common. Our broad prairies, originally beautiful, have been made more grandly so bj' human handi-work, directed by cultured mind. Terrible i)rairie fires may be read about in our history, but they will never more be seen. Our great prairies now are broad realms of finely improved, or improving, pro- ductive and enclosed farms. Good roads are common and the farms dis- tinctly mark them. Streams and sloughs are bridged. Thrifty villages and thriving towns and cities are multiplied while the whole breadth of the country is flecked by beautiful artificial groves. Now, every where over Iowa prairies there are human habitations and the danger to a traveler in a winter blizzard is passed forever. But with all of this improvement and change made by human intelli- gence and industry there are some things pertaining to the prairies of Iowa which are xmchanged. The depth, the richness, the porousness of the soil, qualities which give it superior excellence for agricultural productiveness, are yet unchanged. Proper culture never diminishes but increases its pro- ductive power. The perennial streams coursing through these broad prai- ries, 3'et flow in the same channels cut deep into the earth, with the same, ever continuing, rapid current, yielding untold advantages in their sur- roundings. The prairies of Iowa, no longer grand in their wild luxuriance, have been made more truly beautiful by the art and industry inspired bv our Christian civilization, and will ever be renowned for their agricultural 14 HAND BOOK OF IOWA. superiority. Beautiful, fertile and exuberantly productive, their possessors- are truly a fortunate people. GEOLOGICAL SURVEYS. The first geological explorations in Iowa were made by Dr. D. D. Owen, under United States authority. His field of work embraced parts of Wisconsin, Minnesota and Iowa. His report was published, a large quarto- volume one. The first geological survey in the state was made under the direction of Professor James Hall, State Geologist, in parts of the years 1855, 1856 and 1857, with J. D. Whitney as chemist and mineralogist. Their reports were published in two illustrated volumes by authority of the General Assembly of 1858. In the years 1866, 1867, 1868 and 1869 a second and more extensive geological survey of the state was made by Dr. Charles A. White, State Geologist, Orestes H. St. John, assistant; and Rush Emery, chemist. Their work is reported in two volumes printed by F. M. Mills, state printer, in 1870. The twenty-fourth General Assembly, deeming a new geological survey of Iowa desirable, made an appropriation for the work and appointed a commission to select a suitable geologist to make the survey. This com- mission selected Professor Samuel Calvin of the State University to take charge of the work, Dr. Charles R. Keyes, Assistant State Geologist and Professor G. E. Patrick, chemist. It is believed that this survey will lead to an enlarged development of the mineral interests of Iowa, and a fuller knowledge of the extent and value of its coal fields. A SKETCH OF THE GEOLOGY OF IOWA. By Charles R. Keyes, A. M., Ph. D., Assistant State Geologist. Iowa is so pre-eminently an agricultural state that usually her mineral resources are almost entirely overlooked. Yet her geological features are none the less interesting scientifically, none the less important from an economic standpoint. The mineral wealth of a community can only be developed through a liberal appreciation of its proper functions. Geology ranking first among the useful sciences, has for one of its leading objects the investigation of the natural resources of a region. It considers the characters of the differ- ent soils and their capabilities for agricultural purposes; the extent and value of the different deposits of coal and lead, iron and other ores; the distribution, properties and uses of the exhaustless beds of valuable clays - the accurate determination of the areas for artesian waters; the analysis of the mineral, well and river waters; the relative value and durability of the numerous kinds of building stones; and all kindred subjects which are of the utmost importance to the great body of citizens. Agriculture and geology are daily becoming more intimate in their re- lations. Nowhere has their inter-dependence been more clearly under- stood and nowhere have the benefits been more apparent than in certain A SKETCH OF THE GEOLOGY OF IOWA. ly Europeau countries. Some of the older slates of the Union, especially those along the Atlantic border, have followed the same line of work with the most happy results. To-day it is almost universall}- conceded that a good geological map of a region is practically a soil map also. The proper comprehension of the close relations of the two sciences cannot fail, there- fore, to impress the truth of the statement. In pointing out the various mineral deposits a knowledge of the dis- tribution of the geological formations is of prime importance. Iowa pos- sesses a measureably complete sequence of strata. The Paleozoic beds^ from the Cambrian to the Upper Carboniferous, are very fully represented. The Mesozoic deposits, of Cretaceous age chiefly, are found in considerable thickness. Over all spreads a thick mantle of drift or L'-lacial debris. Below the soft, unconsolidated drift material the indurated sediments' are everywhere exposed through erosion. The complete vertical section of the rocks in the state shows a thickness of about five thousand feet. ALGOXKIAN ROCKS. Sioux Quartzite. The rocks exposed within the limits of the state which are usually regarded as the oldest geologically are those, called the Sioux quartzite or Sioux " granite," which form outcrops of considerable extent in the extreme northwestern corner of the state. While there is na doubt that all the stratified sediments of Iowa rest at no very great depth upon the fundamental complex of crystallines which probably support all the sedimentary rocks of the globe, the Sioux quartzite and its associated masses are the only truly metamorphosed or massive crystalline rocks hav- ing a surface exposure in the state. The common phase of the rock under consideration is a completely vitreous type not unlike red jasper in general appearance and properties. Other parts of the mass are less indurated; and still others are simply loose sand. In places the formation is distinctly conglomeratic. Although the quartzite has been rendered in places so thoroughly crystalline since its original deposition, no igneous rocks have been noted in the vicinitj' until very recently. A few months ago Professor G. E. Culver found in the midst of the Sioux quartzite of southeastern Dakota, within a few miles of the Iowa boundary^ a large exposure of black trap rock, which extends for more than a mile along one of the minor streams flowing into the Big Sioux river. Dr. "W. H. Hobbs, who has made careful microscopical examinations of the rock, finds it to be a coarse-grained olivine diabase — a massive basic rock unquestion- ably igneous in origin. It seems not improbable that further search will reveal other masses of the same rock or even other types of eruptives very similar. In quarrying, the quartzite presents numerous difficulties; but the labor in getting out the material is greatly reduced by the fact that it is everywhere jointed and cracked in such a manner as to enable it to be re- moved readily in convenient sizes for handling. It is one of the most com- pact and durable building stones in the northwest. For architectural pur- Doses it forms a very beautiful stone and is used for all kinds of construc- tion throughout the region. Some of the leading churches and office buildings in Sioux City, Omaha, Council Bluffs, Des Moines, Burlington, and other places have been erected from this rock, with very pleasing effects. %6 HAND BOOK OF IOWA. It has also been used with good results as a paving material both in blocks and macadam. The chief quarries in Iowa are near Rock Ilapids, in Lyon ■county, where the development of the quarry industry, though not so great as a few miles northward and westward, is capable of great expansion, since the stone may be obtained in practicaly inexhaustible quantities. Reference has been made to the occurrence of igneous rocks near the state boundary. It may be of considerable interest therefore to mention the fact that in sinking a number of deep wells in different parts of northwestern Iowa the drills have passed completely through sedimentary rocks into the ■crystalline basement below, penetrating the latter in some cases to the extent of several hundred feet. At one of the latest borings, at Hull, in Sioux county, several thick beds of flint-like rocks were passed through, the different layers being separated by sands and gravels. These flint-like layers were found to be typical quartz-porphyry, a truly igneous rock, or lava, very acid in nature and essentially identical with granite, but cooling oinder somewhat different physical conditions. The presence of these massive crystalline rocks is very suggestive of agencies that may have been involved to some extent in metamorphosing the old Sioux sandstone. CAMBKIAN. Saint Croix Sandstone. In the extreme northeastern corner of Iowa, at the base of the high bluffs along the Mississippi river and its tributaries there is exposed a thick unconsolidated sand bed, which has been called by Minnesota geologists the Saint Croix sandstone. Its greatest thickness shown in Iowa is about two-hundred and fifty feet; but it is known to have a thickness of not less than one thousand feet, as has been disclosed by borings. While for the most part it is a soft sandstone wearing away rapidly under atmospheric influences there are in places clay seams and thin layers of lime-rock frequently developed. In the neighboring states the calcareous and argillaceous beds assume a much greater importance and form shales and shaley limestones which are charged with the remains of trilobites. This sandstone has been called by most writers on the geology of the Upper Mississippi Valley the "Potsdam," and has been re- garded as the western extension of the formation known by that name in New York. There is but little doubt, however, that the Saint Groix is very ■distinct from the Potsdam sandstone of the Appalachian region, though the fauna is possibly equivalent to the si miliar one of the New York horizon. Although the formation has such a thickness in Iowa no subdivision of it into minor beds has been attempted. It does not have so great an impor- tance in this state as in the neighboring regions of Wisconsin and Minnesota. As a whole the Saint Croix sandstone of Iowa is of little economic value. At Lansing and some other localities there are thin beds of this formation which are sufficiently compact to furnish building stones of inferior quality. These layers are as yet only used for rough masonrj% As most of the sand- stone is very incoherent, it will furnish unlimited quantities of coarse and fine building sand; while certain light colored layers could be used for the manufacture of glass. SILURIAX. Oneota Liviestone. The name of this formation is that proposed by A SKETCH OF THE GEOLOGY OF IOWA. 17 McGee for the rock usually known as the Lower Magnesiau limestone. Though attaining a thickness of between two and three hundred feet it is exposed onl}- over a small area in the northwestern portion of the state. Along the borders of the Mississippi it rises above the soft Saint Croix sand- stone in bold escarpments and castellated walls. For the most part the rock is a rather impure dolomite with occasional thin sandstone layers in the upper part. In color it is buff to brown. It is often vesicular and cavernous. In Wisconsin and Minnesota the lower Magnesian limestone embraces other layers than those represented in Iowa. The principal beds thus referred to are called the Willow river limestone and New Richmond sandstone in Wisconsin and the Shakopee limestone and white sandstone in Minnesota. The Oneota limestone is quarried at Lansing, Waukon, McGregor and other places in Clayton and Allamakee counties. For all ordinary masonry it supplies unlimited quantities of good material. Lime of a very good quality is also manufactured from this rock at a number of places- In certain localities considerable amounts of lead ore are found, but as yet this mineral has not been mined to any great extent in the lower Magnesian limestone. Saint Peter Sandstone. Overlying the Oneota limestone is a heavy bed of pure silicious sandstone, very friable and with few lines of stratification. It is sometimes somewhat indurated, but as a rule incoherent. This is the formation that has long been known in the Cpper Mississippi region under the name of the "pictured" rocks, best exposed perhaps in the vicinity of McGregor. Along the boundarj' of the state northward thin limestone layers are often intercalated. In places this sand formation graduates downward by a rapid increase of calcareous matter into the Oneota lime- stone. Economically it is of considerable importance in Iowa. Many of the layers are very pure and form excellent material for the manufacture of glass. Trenton Limestone. Contrasting sharply with the other Silurian lime- rocks of Iowa the Trenton is an ordinary blue limestone instead of a dolo- mite. For the most part it is a very compact rock, and often fossiliferous. Owing to its difference in lithological characters as compared with the other Silurian limestones it is honeycombed in places by cavities and caverns of greater or less extent. "It constitutes a conspicuous feature of the Mississippi river bluffs from above McGregor to near Eagle Point, Du- buque, and occurs as the surface rock over all or part of the counties of Allamakee, Howard, Winneshiek, Fayette and Clayton. The Trenton limestone is interesting to the scientist on account of the number and beauty of the fossil remains inclosed in some of the strata. Here occur the oldest types of life that have been preserved in an}- degree of perfection within the limits of the state. The old Potsdam trilobites are few and frag- mentary, and their structural characters are very obscure. In the Trenton are found countless multitudes of organic remains literally crowded to- gether, and retaining in absolute perfection every structural feature even to the minutest detail. Owing to the slight southerly or southwesterly dip the strata pass successively below the level of the IMississippi river, and so just above Dubuque the Trenton limestone disappears from view." (Calvin.) i8 HAND BOOK OF IOWA. The Treutou limestone is quarried in numerous places throughout the counties mentioned. Lime of very good quality is made of this stone. Certain of the clay shales afford good material for the manufacture of light colored brick. Oalena Limestone. Overlying the Trenton limestone in northeastern Iowa is a heavily bedded brown dolomite which attains a miximum thick- ness of between two and three hundred feet in the vicinity of Dubuque. In many places it is very coarse, vesicular and unevenly textured. It frequently contains some cherty matter. The entire bluffs at Dubuque are formed of this limestone. Some sandy material is present in different portions of the formation. The partings are usually argillaceous and are more massive and important toward the top where the formation gradually passes into the overlying shales. As shown by Chan>berlain, the conditions of the deposi- tion, in southwestern Wisconsin and vicinity were changed somewhat from those which had existed during the Trenton. One of the most characteristic features of the Galena limestone is the surface fissures which everywhere traverse this formation. Sometimes they are mere vertical cracks or horizontal partings of the strata, but often widen out into broad cavities. In these openings are found the lead and zinc ores of the region. The metallic ores taken from this limestone form perhaps one the most important economic characters. It was in the Dubuque region that the lead ore of the upper Mississippi valley was first mined in a system- atic way. The Galena limestone furnishes a considerable quantity of good material for heavy masonr}'. The chief quarries are located at Dubuque, though every- where throughout its geological range the rocks are adapted and used for ordinary building purposes. A superior quality of lime is also manufac- tured from this rock. Maquoketa Shales. Along the entire western slope of Turkey river and below the mouth of that stream on the Mississippi as far as Clinton county, there is exposed between the Galena limestone and the Niagara an extensive bed of bluish or greenish clay-shale. Disintegrating readily under the influence of weathering, these shales allow the massive overlying dolomities to form a bold, mural escarpment which extends the entire length of the river mentioned. The shales have not been reported north of the Iowa boundary. Beginning at a point in Winneshiek county about twenty miles from the Minnesota line the ]\[aquoketa shales have a thick- ness of over a dozen feet or more. This thickness rapidly increases till at its southernmost exposure it attains a vertical measurement of more than one hundred and twenty-five feet. At Dubuque a few feet of these shales are seen in isolated patches in the summits of the bluffs. For the most part these shales form alternating bands of dark and light colored clays with occasional thin seams of impure limestone. On the upper Maquoketa where the typical locality is situated, the shales are highlj' charged with many species of fossils. This formation is of small economic importance, unless the clays can be utilized in the manufacture of brick and pottery. Upper Silurian. The "Niagara" escarpment which rises in great prominence on the western slope of Turkey river and continues southward along the Mississippi nearly to Davenport is one of the most important A SKETCH OF THE GEOLOGY OF IOWA. 19 topographical features in northeastern Iowa. The upper Silurian lime- stones which form this elevation in Iowa are massive dolomities yellowish or brown in color, having a very considerable thickness. Although pre- senting great uniformity in texture there are locally large amounts of cherty material in bands or irregular nodules. Silicious material is also often disseminated in fine particles throughout the rocks, but as a rule it is con- centrated into the masses already referred to. Chemical analysis of the limestone itself shows that most of the form- ation is a very pure magnesiau limerock or dolomite with scarcely any foreign material. In different layers the percentage of lime and magnesia vary somewhat. In a few cases the latter is almost entirely wanting and the beds assume the condition of a normal limestone. From its southern exposure where it is thought to attain a thickness of more than five hundred feet it rapidlj^ thins out northward until just beyond the Iowa-Minnesota line its vertical measurement is very insignificant. At the southern end it is heavily bedded. In many places the inclination of the beds is very considerable, sometimes as high as sixty degrees. Lying directly upon the inclined strata are often seen perfectly horizontal beds. At first sight it appears as if there was a marked unconformity. But from a careful examination of some of the exposures it seems probable that the apparent dip is in some cases due to false-bedding on a large scale. In other instances it may be that very decided disturbances have occurred in the strata. The exact subdivisions of the upper Silurian rocks in Iowa is yet some- what undetermined. Hall in 1858 regarded the limestone as made up of an upper member which he termed the Le Claire limestone and a lower por- tion which was regarded as the same formation to which in New York the name IS iagara had been applied. With the exception of White, all geolo- gists who have examined the upper Silurian strata in Iowa regard these rocks as made up of at least two distinct formations. These subdivisions greatly differ not only faunally but in a less marked degree in stratigraph- ical and lithological characters. For the reason set forth above, Hall's Le Claire appears to be a desirable name for the upper member as now under- stood; while Niagara, for the present, will be retained for the lower mem- ber. For the latter term some other name will probably have to be substi- tuted after a further investigation of these rocks has been made. Perhaps no other geological formation in the state furnishes a better qualitj'of building stone for general purposes than the upper Silurian strata. The great extension of these rocks both in thickness and surface area make the supply inexhaustible. They form also the best lime in the world. This industry has already begun to assume very considerable proportions in this state. DEVONIAN. The broad belt of Devonian rocks in Iowa is traversed medially its en- tire length by the Cedar river, the beds of this age extending from fifteen to twenty-five miles on each side of the stream. The formation is made up chiefly of massive limestones with magnesian layers. These rocks form one of the most important geological horizons in the state. Although widely known in a general way their details are as yet little understood, as 20 HAND BOOK OF IOWA. the various uiinor subdivisions recognized by different writers readilj' show. Until much additional information has been obtained it seems desirable to recognize now only four sections of the Devonian in Iowa. Some of these formations will probablj^ require further breaking up as the rocks become better understood. Regarding the equivalents of the Iowa Devonian beds with the more eastern formations much has been written, but as yet no satisfactory results have been obtained. Independence Shales. For a long time the Devonian beds of Iowa ■were regarded as made up almost entirely of limestones. Hall and others foimd clay beds iu the northern part of the state; while still more recently Calvin has discovered important shales layers at the base of the Devonian, in Buchanan county. The latter beds are made up of dark carbonaceous claj's with thin bands of impure concretionary limerock. In places the shales are so highly charged with bituminous' matter that considerable ex- citement has been caused at different times, on account of their supposed nearness to coal deposits. Remains of plants have been found scattered through these clays; and they have also accumulated so abundantly locally as to form thin veins of true coal. The shales also yield a very consider- able number of animal remains. Cedar Valley Limestones. As already remarked the greater portion of the Devonian in Iowa is made up of limestones, for which it seems desirable to revive Owen's old name of Cedar Valley. These limerocks present very considerable differences in lithological characters. Although for the most part they are ordinary limestones they pass rapidly into argillaceous, dolomitic or even bituminous phases. Many of the beds are very massive though others are somewhat shaley. Everywhere the rocks of "this age are highly charged with fossils of many kinds. Some of the most valuable building and ornamental stones occurring in Iowa are of Devonian age. Perhaps the best limestones for heavy masonry found anywhere in the state are those quarried on the Iowa river north of Iowa City. The old state house at the place just mentioned, and the basement of the new Capitol building at Des Moines were both con- structed of this rock. Unlimited quantities of good building stone are ac- cessible in the Devonian throughout the exposed area. Abundant supplies for the manufacture of quick-lime are present everywhere but the quality of lime is not as good as that furnished by the upper Silurian strata. Montpelier Sandstone. This name is applied to certain arenaceous beds that are well exposed in Muscatine county, and which have been recently differentiated by Calvin from the lower Carboniferous sand-rocks found farther to the southward. They are Devonian in age, but were formerly regarded as being identical with the Kinderhook sandstone exposed in the vicinity of Burlington. The Montpelier sandstone lies immediately above the Devonian limestone. The chief exposures of this rock are near the mouth of Pine Creek in the county mentioned. It is composed of yellowish or brownish material, somewhat friable, but in places indurated sufficiently to afford blocks for common masonry. Large quantities of this rock have been quarried and used for the rip-rap which extends for many miles along the Mississippi above Muscatine as a pro- tection for the railroads from the waters of the river. A SKETCH OF THE GEOLOGY OF IOWA. 21 Lime Creek Shales. These beds have long been supposed to form the uppermost member of the Devonian in Iowa. The are well exposed ia many places in Floyd county especially. Some of the most important out- crops being at Rockford and along Lime Creek. At the latter place there is exposed a vertical thickness of about one hundred feet of dark argilla- ceous shales which are highly fossilferous. They disintegrate rapidly under the influences of the weather, forming a plastic clay which will probably prove quite valuable for the manufacture of brick. The geo- graphic extent of these shales is not known at present; nor is their strati- graphic position fully understood. CARBONIFEROUS. Lower Carboniferous or Mississippian Series. At the base of the Carboniferous rocks as represented in Iowa and forming one of the most important geological formations exposed within the limits of the state is the great series of limestones which have commonly been termed the " Subcarboniferous." These rocks in Iowa form a sinuous belt twenty-five to forty miles in width midwaj' between the Cedar and Des Moines rivers. The zone mentioned thus extends from the southeastern corner of the state northwestward as far as the Minnesota line. In southeastern Iowa the lower Carboniferous rocks form percipitous bluffs along the Mississippi and Des Moines rivers and their tributaries. The Mississippian series as represented in the continental interior is made up of four distinct formations. Only three of these however are exposed in Iowa. They are the Kiuderhook, Augusta and St. Louis formations. Kinderhook Beds. In the southeastern part of the state the Kinder- hook beds are largely hard clay-shales with occasional bands of limestone. At Burlington these shales attain a thickness of over two hundred feet, not ail of which, however, are exposed above the water level of the Mississippi river. Lithologically this formation as exposed at Burlington is a massive claj'-shale, often highly calcareous and in the upper part contain silicious matter in the form of tine j^ellow sand which occasionally assumes the character of a soft sandstone. Below the sandy portion these shales have long been supposed to be destitute of fossils, but recent exposures have disclosed faunas of a most interesting and instructive character. A short distance below Burlington near the mouth of the Skunk river these shales disappear below the water-level. At Keokuk, as has been shown hy recent borings, they are in the neighborhood of one hundred and fifty feet below the water-level in the Mississippi. At Burlington immediately beneath the Burlington limestone are several beds a few feet in thickness of limestone and oolite. These are separated by clay shales. The exact relation of these beds to the rocks farther southward in Missouri is not known at present. Beyond the immediate vicinity of the Mississippi river the shales in question are not exposed at the surface in Iowa; but they apparently have a considerable geographical extent and are thought to be recognizable in a number of deep well sections in different portions of the southeastern part of the state. A hundred miles northwest of Burlington, in Tama and Marshall 22 HAND BOOK OF IOWA. counties, rocks which have been referred to the Kinderhook are well exposed along the Iowa river and some of its tributaries. The exact correlation of these beds with those of southeastern Iowa has not as yet been fully made out. As shown in the LeGraud quarries the formation is chiefly a rather soft, somewhat irregularly bedded, buff limestone, probably containing a considerable percentage of magnesia. It seems from an examination of the fossils contained in the Le Grand beds that a part of them at least correspond to the limestone at Burlington. In southeastern Iowa no good quarry rocks have been found in the Kinderhook formation. Occasionally the oolitic beds are used, but thej^ withstand weathering only a short time. The clay-shales at Burlington have recently been brough into prominence in the manufacture of paving brick. Toward the northern limit in Iowa the Kinderhook assumes a cal- cerous facies. It is extensively quarried at numerous places in Humboldt, Hardin, Grundy, Tama and Marshall counties. In the latter localities the rock is a fine-grained limestone and forms a very durable building stone. It has been used largely for bridge piers and architectural purposes. Portions of it contain ferric-oxide in narrow veinings. It takes a fairly good polish and is extensively used for interior work in place of ordinary marble. The lower part of the Le Grand section is made up of ver}' com- pact oolitic rock which withstands very well all weathering influences, as is shown in the court house at Marshalltown which is constructed almost entirely of this stone. August A Limesto'iie. The two formations commonly known as the Burlington and Keokuk limestones have recently been found to form properly but a single sequence of rocks. The Burlington and the Keokuk groups are called after the cities of the same name in southeastern Iowa. At these localities the rocks have been regarded as typical developments. A care- ful examination of the fossils contained and of the relations of the different beds indicate that the limestones under consideration W'hich were formerly considered as two distinct formations should be included under a single term. The lower portion of the formation commonly known as the Burling- ton limestone is a coarse-grained, encrinital rock, usually white and very pure in certain layers. It often contains considerable ferric-oxide and cou- sequentlj' a reddish hue is imparted to it upon exposure. The lithological characters of this rock are remarkably constant over broad areas. There are also in certain places silicious beds, the lowermost of which have thick- ness of twenty-five feet or more. They are made up largely of nodular masses and irregular bands of chert with some calcareous matter. There are other layers of flint of equal if not greater importance in the Augusta beds than those just mentioned. The so-called Keokuk limestones are essentially the same as the Burlington rocks. They are usually more com- pact, less fossiliferous and have a bluish cast instead of the pure white color. The upper portion of the formation also contains beds of clay-shales. The Augusta Limestones are quarried rather extensively; the chief localities being at Columbus .Junction, Burlington and vicinity. Ft. Madison, Keokuk, Bonaparte, and Bentonsport. The rocks at Burlington are used for ordinary masonry; some of the layers, the more massive ones, A SKETCH OF THE GEOLOGY OF IOWA. 23 fonriing fairly good material for building. Large quantities of good lime could be manufactured, but at the present tim^ only a few small kilns are in operation. Farther southward in Missouri, the Burlington limestone is quarried largely for the manufacture of lime as well as for ordinary masonry. The lower layers at Keokuk have been used for bridge work and all kinds of common masonry. A good quality of lime is burned at various points in the vicinities of the places just mentioned. The sandy magnesian layers at the top of the Keokuk limestone have been extensively used for building and a number of churches and other structures are com- posed of this material. Along the Des Moines river the rocks of this form- ation were formerly used in the construction of dams at the time when slack-water navigation was proposed for the Des Moines river. St. Louis Limestone. The rocks of this stage have commonly passed under the name of Concretionary limestone. But they are the same as those developed at the mouth of the Missouri river which Shumard called after the city of St. Louis. The northern limit of these rocks is one hun- dred miles beyond any known exposure of Augusta rocks. From this northern border nearlj^ to the mouth of the Missouri river the limestone is comparatively thin; but southward from the latter point it thickens rapidly until it attains a measurement of more than two hundred feet. Everywhere over the northern area of the St. Louis, characteristic brecciated rocks are seen. In Iowa this formation has probably a surface exposure much greater than any other member of the Lower Carboniferous. It is usually a fine-grained, compact, bluish rock breaking with conchoidal fracture. The upper por- tion of the formation is often covered by a white, highly fossiliferous marl. The St. Louis limestone is made up largely of pure calcium carbonate. Quick-lime is manufactured at numerous places everywhere throughout the range of the formation. At Tracey, and elsewhere in Marion, Wapello and Van Buren counties certain of the St. Louis rocks furnish excellent material for heavy constructional purposes, bridge piers and foundations COAL MEASURES. From an ■economic standpoint the mo.=it important geological formation in the state is that yielding coal. The strata of Iowa furnishing this valu- able product form the northernmost extension of the great interior coal field of the American continent. The beds occupy the southern third of the state and are distributed more or less extensively through one-half of the entire number of counties. The area covered by the Carboniferous strata is therefore not far from twenty thousand square miles. It must not be inferred, however, that the coal is equally distributed over all this dis- trict, for such is not the case. The broad belt running southeast and north- west and traversed its entire length by the Des Moines river from Fort Dodge to Keokuk has heretofore been found to be much more productive of coal than other parts of the region. Lately in many places outside of the belt named, coal has been discovered in abundance, often where its presence was unsuspected before. Taken as a whole there are two kinds of beds, sharply contrasted, which go to make up the Coal Measures of the state. The first is marked by a great predominance of clay shales and sandstones, often to the total ex- clusion of the limestone. The individual beds have usually a very limited 24 HAND BOOK OF IOWA. extent and replace one another in rapid succession. On the otlier hand, the second class of sediments above mentioned is made up chiefly of cal- careous shales with heavy beds of limestone. The laj^ers are evenly bedded and extend over very considerable areas. As the conditions of deposition were evidently those of a slowly sink- ing shore the marginal deposits as a whole practically underlie the open sea formations, the former being regarded as the "Lower" Coal Measures and the latter as the "Upper" Coal Measures. At the same time it must be remembered that this does not necessarily imply that the "Lower" meas- ures are to be considered much older than the "Upper;" but rather that along the great and successive planes of sedimentation different beds of the upper and lower divisions were laid down contemporaneously. The limits of the two formations in Iowa thus assume somewhat different lines from those that have commonly been recognized. It has been proposed, therefore, to divide the Coal Measures, or L^pper Carboniferous, into: (2) The "Upper" Coal Measures, or Missouri Stage. (1) The "Lower" Coal Measures, or Des Moines Stage. The Des Moines formation represents the Lower Coal Measures or mar- ginal deposits of the upper Carboniferous. It takes its name from the Des Moines river which flows for more than two hundred miles directly through the beds of this terrane. It extends into Missouri forming the northern and western boundaries of the Ozark mountains and extends still farther southward into Kansas and Indian Territory. The Missouri formation corresponds essentially to the upper Coal Measures, representing the more strictly marine deposits. It is tlie form- ation typically developed in the northwestern part of oMissouri. The Mis- souri river also winds its way for more than four hundred miles through the beds of this stage, exposing numerous fine sections on both sides of the stream throughout the entire distance. In the order of their abundance the rocks of the Coal Measures are clay-shales, sandstones, limestones and coals. The secondary part that the calcareous beds play in the Coal Measures of the state, especially in the lower division, contrasts this formation with the other paleozoic rocks. Below, the Coal Measures rest on a great basement of massive limestones- with but few clayey or sandy beds of separation. Not less striking is the relative thinness, as a rule, of the individual layers which replace one another upwards and laterally in rapid succession. If tlie upper and lower divisions of the Coal Measures in Iowa were to be contrasted upon litho- logical characters alone it would be found that the former is prevail- ingly lime bearing; the latter largely clayey. Little need be said here concerning the quality of the coals of the state. They are all of the bituminous variety and are fullj^ described in another place. The carbonaceous seams vary from a few inches to seven or eight or even ten feet in thickness; the average of the veins at present worked is between four and five feet. These beds are deposited not in two or three continuous layers over the entire area, as has been commonly supposed, but in more or less lenticular masses varying from a few feet to several miles in extent. A SKETCH OF THE GEOLOGY OF IOWA. 25- The stratigrapliical importance of the coal seams is not so great as has been generally supposed, since the bituminous beds are, with very few exceptions rather limited. Only a single case is at present known in which the geographic extent of a coal stratum is more than a few miles, and for a part of this distance the coal is but two or three feet in thickness.. On the other hand, the amount of coal in the state, is probably very much greater than has been commonly supposed. For reasons which need not be stated in detail here, considerable difficulty has been encountered in working out the structural features of the Coal Measures of Iowa. The general inclination of the beds is to the south- westward. Careful estimates indicate that the greatest thickness of the Lower Coal Measures in the state is probably in the neighborhood of four hundred feet; and that the maximum vertical measurement of the upper division is thrice that figure. Erosion has removed much of the coal bear- ing strata of this district and the original thickness of these rocks is not now represented at any one place. The basal coal seams of the Lower Coal Measures of Iowa appear to be much more extensive than those toward the top, where they are only a few inches in vertical measurement and perhaps a ' hundred yards in extent. The coal may therefore be regarded as disposed in numerous basins of greater or less area, thickened centrally, but gradually becoming attenuated toward the margins. These are arranged in various horizons interlocking with one another, but separated by varying thicknesses of sand- stone and shale. Thus at any one point a dozen or more seams may be passed through in sinking a shaft, several perhaps being workable. The disposition of the coal in numerous limited lenticular basins instead of a few layers extending oyer broad areas is of the utmost importance from a purely economical standpoint. In all mining operations and in all prospecting it is very essential that this fact be kept constantly in mind. With methods of boring more modern than those commonly in vogue throughout the western states there is every reason to believe that in the Lower Coal Measures especially the large majority of good coal seams twelve inches in thickness and over encountered in prospecting may be traced readily and easily to localities where they are thick enough for profitable working. In Iowa the restrictions upon the distribution of the individual seams are not numerous as compared with other regions. Yet there are disturbances of various kinds which break the continuity of the coal strata, locally interfering slightly with mining operations. They are referable to the three general agencies of deposition, erosion and dislocation. From careful estimates made from reliable sources the production of coal for the past year amounted to more than 5,340,000 tons, valued at $7,- 750,000. By comparisons it will be seen that Iowa as a coal producer ranks first among the states west of the Mississippi river and fifth among the states of the Union. Throughout all of the Coal Measures in Iowa occur unlimited quantities- of clay of excellent quality for the manufacture of paving, pressed, fire and otiier kinds of brick. An excellent quality of potter's clay and material for tiling, terra-cotta, and in fact nearly all other kinds of clay products, are plentiful. 26 HAND BOOK OF IOWA. CRETACEOUS. Although formerly known to be exposed only over a small area near ■Sioux City, the Cretaceous rocks of Iowa have recently been found to occupy a very considerable district in the northwestern portion of the state. On account of a thick mantle of drift over all this portion of the state there is considerable difficulty in locating the exact boundary along the eastern margin of the deposits. From numerous borings, however, the Cretaceous beds have been recognized over more than a dozen counties, showing that the approximate eastern boundary is a somewhat sinuous line running through a point midway between Sioux City and Council Bluffs nearly to Fort Dodge and thence bending northward. Beyond the limits of this line numerous outliers have been recognized, some appearing more than fifty miles beyond the boundary mentioned. There are four formations in Iowa which are probably referable to the Cretaceous, though the exact stratigraphical equivalents of two of these, the Fort Dodge gypsum deposits and the Nishuabotna sandstone are at present somewhat doubtful. Nishnabotna Sandstone. Although the beds under consideration have usually been referred to the Cretaceous they have never been directly "traced to the outcrops of the Woodbury shales. The geographical distance between the nearest exposures of the two formations as at present known is very considerable. If the Nishnabotna is Cretaceous it may be the equivalent either of the Woodbury shales or of the Niobrara chalk; which one it is cannot now be stated. In regard to the gypsum beds their form- ation indicates a saline lake deposit such as might be left by a retreating -ocean. This fact taken in connection with the probable great eastern ex- tension of the Niobrara suggests that the Fort Dodge beds were formed dur- ing the retreat of tfie Niobrara waters through Iowa. At the present time it seems best not to attempt a specific correlation of the gypsum deposits, nor of the Nishnabotna sandstone, but merely to regard them as Cretaceous in age. The sandstones and loose sands that have been called Nishnabotna are to be regarded as shore deposits; along with numerous other beds of similar char- acter which occasionally are found as outliers through central and northei'u Iowa. The Nishnabotna as reported by White has a thickness of fift}- to seventy-five feet, and is seen exposed in the southeastern part of Guthrie countj^ southern Montgomery county, and elsewhere in the western part of central Iowa. Quarries have been opened in these rocks at Lewis, in Cass county. In its lithological characters the formation is a coarse-grained, ferruginous sandstone, dark brown in color and usually quite friable. Occasionally thin clay seams are intercalated. Fort Dodge Beds. This name is applied to the gypsum deposits and •certain associated beds which are well exposed in the neighborhood of Fort Dodge. The gypsum attains a vertical measurement of from two to thirty feet, its average thickness being perhaps about fifteen to sixteen feet. It occupies an area, in the central part of Webster county, of about twenty-five square miles. It is traversed north and south its entire length by the Des Moines river and is cut through by many of this stream's smaller tributaries A SKETCH OF THE GEOLOGY OF IOWA. 27 Probably more than one-half of the entire deposit has been removed through erosion by the chief water course. The most extensive exposures now open are about six miles below Fort Dodge. To some extent the massive gypsum of Fort Dodge has been cjuarried for building purposes. A number of buildings and foundations have been ■constructed of this material. It has also been used quite extensively for heavy masonry. Its most important use, however, is its manufacture into stucco and land-plaster. During the past year more than fifty thousand tons of these materials were prepared in the vicinity of Fort Dodge. Woodbury SJutles. As already intimated, the typical outcrops of this formation are to be seen in Woodbury county along the Big Sioux river. The formation corresponds essentially with the Dakota and Fort Benton groups of Hayden. The beds represent shore deposits and it seems desir- able to retain the name in preference to the two proposed by Hayden. "Woodbury" as defined by White expresses more accurately than any other name yet proposed the lithological features of the rocks as represented in Iowa. The Woodbury shales are made up in certain places largely of the sandstone, which sometimes form hard concretionary masses not unlike quartzite. In some localities these masses are so near together that they may be quarried to advantage for building stone. The most important of these openings is in the vicinity of Sioux Cit}' and is now known as the Rees' Granite quarry. The rock has apparently all the qualities of the regular crystalline massive rocks. The greater portion of the Woodbury shales is argillaceous and afford inexhaustible quantities of good clay for the manufacture of pottery, fire and paving brick. Niohrara Chalk. These beds in their chalky facies have been ob- served in Iowa in the vicinity of the Big Sioux river. They are probably represented farther eastward by more strictly shore deposits. They consist of tine soft calcareous layers appearing not unlike clay at first glance. These chalky layers in connection with the clays form excellent material for the manufacture of Portland cement. This industry has already begun under favorable circumstances on the Missouri above Sioux City. PLEISTOCENE, OR SURFACE DEPOSITS. Over all Iowa, covering the indurated rocks to a depth of from a few inches to two or three hundred feet, is a mantle of loose incoherent material. This material is chiefl}' of three kinds; known as the drift, loess, and alluvium. The latter may be regarded as the deposits of the modern rivers, the two former as glacial debris. Alluvium. Little need be said here in regard to the alluviul deposits. They are the fine sediments laid down in the river vallej's making up what is commonly known as the flood plain. Man}' of the river terraces are also alluvial. These materials will be treated at length in another place in con- nection with an account of the soils of the state. Drift. To the heterogeneous mixture of clay, sand, gravel and boulders which is seen everywhere throughout the state there has been applied the name of drift. Everwhere the proportions of these drift constitutents vary. It changes rapidh' from place to place passing from one kind into another. The clays form by far the largest portion of the mixture and is 28 HAND BOOK OF IOWA. usually mingled with more or less fine sand. In color it has a characteristic brown or buif tint. When excavated the surface exposed quickly breaks up into. small cubic or angular fragments commonly known as joint-clay. The sand and gravel often form considerable beds yet they are usually quite limited in extent. The boulders are chiefly of crystalline rocks of northern origin. They represent a great variety of eruptive and metaniorphic types.. The drift is largely of glacial origin. It has been shown in Iowa to be made up of two sheets. The lowest or earliest drift forms a part of the great drift mantle extending over northern United States. In the Mississippi valley it has its southern boundary along the line of the Ohio- and Missouri rivers. The upper till belongs to a later glacial epoch and is included within the area bounded by what is known as the moraine of the Des ]\Ioiues lobe of the second great ice invasion. This forms a narrow tri- angle in Iowa with its apex reaching to the city of Des Moiues. Loess. This deposit is well displayed along the Missouri and! Mississippi rivers and at numerous places throughout the interior of lowa.. It is a fine homogeneous clay-like material which seldom shows any tendencj- toward stratification. It is friable enough to be impressed with the finger- but resists weathering in a remarkable way. The surface deposits of the state belong chiefly to the Quaternary age of geology. Over a great part of Iowa the soils are formed directly through these deposits. The purer clays afford good material for the manufacture of brick; while certain portions afford sand which can be utilized in glass making. CLIHATOLOGY OF IOWA. By John R. Sage, Director Iowa Weather and Crop Service. The prime factors of agricultural prosperity are a fertile soil and sx favorable climate, the latter being the more important. There are in this country millions of acres of soil, which, though abundantly supplied with the elements of fertility are comparatively worthless, because of unfavor- able climatic conditions. Nothing can fully compensate for the lack of rainfall in the growing season, for only a small portion of any arid region can be made productive by irrigation. The claim may be made in behalf of Iowa that in respect to these two essentials, soil and climate, it stands foremost among the agricultural states- of the Union. There is no question as to the exceeding richness and dejtth of its soil, for it has maintained a large measure of its original fertility under a system of continual cropping which would have reduced to barren- ness the thinner soils of less favored sections. And its climate has served as a fit complement of its soil in the production of those vast crops which have figured so conspicuously in the agricultural statistics o^ the country. The establishment of the National and State weather bureaus has in- cited public interest in questions relating to the climate of the different sections of our greatly diversified country. And the census reports have revealed the fact that the settlement of the country and increase of popula- CLIMATOLOGY OF IOWA. 29 tion bear a verj- definite ratio to the average yearly precipitation, mean ■temperature and tlie general climatic conditions affecting crop production and the public health. People who are about to emigrate, to better their condition in life, are largely influenced in their choice of a new home by such facts as they are able to obtain relative to climate. With the larger number this is very properly a consideration of chief importance. WEATHER KErORTS. Fortunately we have at hand ample meteorological records to illustrate the constants of temperature, humidity, wind movement and the general characteristics of the climate of Iowa. Weather observations were begun at the military posts in the territory as early as the year 1820, and records were made with some degree of regularity under military auspices until 1849, when the Smithsonian Institution, aided by the general government, took up the work of systematic observation, establishing stations wherever intelligent observers could be secured. Since 1871 this work has been done under the auspices of the National and State weather services. There is, there'fore, no lack of material, in the form of official records, from which we may obtain a knowledge of the more important features of Iowa's climate. A careful stud}' of the voluminous data will convince any one interested in the subject that for all-the-year-round residence, for the promotion of health, physical vigor and agricultural prosperity there is no more favorable climate in America than in this favored section of the great Mississippi valley. GENERAL CIJMATIC FEATURES. Situated near the geographical center of the United States, the climate is strictly continental. This term being used in contradistinction to marine climate implies that it has winters of considerable severity, and summers of unusual warmth, with large seasonal and daily temperature ranges, a generally dry and salubrious atmosphere, small percentage of cloudiness and large percentage of sunshine. The altitude of the State ranges from -144 feet above sea-level at the confluence the Des Moines and Mississippi rivers, to 1,650 feet at a point near Spirit Lake; and as there are no mountain ranges nor extensive forests the physical conditions give to the State a homogeneous climate, with only such variations of temperature, rainfall and other meteorological elements as result from latitude and elevation. Despite its remoteness from the sea its climatic characteristics are re- markably constant; in fact, no section of the country enjoys a greater de- gree of uniformit}' of the conditions favorable to the production of the staple crops. In attestation of this it may be stated that, Avhile there have been seasons of variable productiveness, there has never been a total failure of the principal crops in this State since the virgin soil was first broken by the plow-shares of the white settlers. The climate of this section is affected by the general topography of the continent, the great mountain ranges, and the oceanic and atmospheric cur- rents, all of which must be duly considered in a thorough study of the subject. A glance at the map of the continent will show a great central depression extending from the Gulf of Mexico to the Arctic sea, formed by the vast mountain ranges at the v.-est and the lesser uplift skirting the Atlantic coast. This interior vallev is much wider and somewhat lower at 30 HAND BOOK OF IOWA. the north than at the south, and two-thirds of the drainage of the continent flows northward. The upper Mississippi valley, of Avhich Iowa is a part^ forms the water-shed about midway between the Gulf and Hudson Bay. It has been stated that in time of high water a canoe can be rowed from the Mississippi up the Minnesota to its source in Big Stone Lake, and thence across a slough to Traverse Lake, the source of the Ked River of the North. The altitude at this point where the waters of the Gulf and the Arctic ocean are in touch is less than one thousand feet above sea level. Through this vast channel in ancient geologic periods the glaciers pushed their way, forming the drift deposits, and laying the foundation of soil of the most productive empire on the surface of the globe. And now^ in these latter years, this mid-continent depression gives free passage to the boreal breezes from the north and the humid winds from the south,, which here meet and commingle to refresh the earth with copious showers in the season when they are most needed. It is easy to see what an impor- tant pa4't is borne in the climate of the interior by the great physical feature herein described. If the mountain ranges crossed the continent east and west, instead of north and south, this central valley would be a veritable desert, instead of the garden and granary of the w^estern hemisphere. The cool waves from the north and the vapor-laden winds from the south are equally important factors in making this a habitable, productive and pros- perous region. PRECIPITATION. The moisture pi-ecipitated over Iowa and contiguous portions of the Mississippi and Missouri valle^ys comes almost entirely, either directly or indirectly, from the Gulf of Mexico. The warm southerly winds, heavily laden with humidity from that source, drawn hither by the passage of low area storms from the west, deposit a portion of their moisture in advance of the storm centers as they move toward the Atlantic. Following in the rear of these depressions the cold and dry air from the northward condenses the remaining moisture in the rear quadrants of departing storms. These alternating currents flowing northward and southward through the valley, with their sharp contrasts of temperature, brought thus into action by the passage of low areas across the continent, form the warp and woof of the fabric of the weather of this section. And as the Gulf, which is the great fountain of humidity whence our annual supply of moisture is drawn, is permanent, and the atmospheric waves of high or low pressure are con- stantly passing, there is no danger that this region will become arid and unproductive. The people may safely bank upon the permanence of their climate and an ample supply of moisture. Various early historic publications placed the average yearly precipi- tation of Iowa at forty-four to forty-seven inches. These figures are too high, being obtained from insuflicient data. The correct mean obtained from all available records, covering a considerable number of years in all sections of the state is about thirty-five inches. Blodgefs rain chart for the continent shows the average annual pre- cipitation in the eastern and southeastern counties to be forty-two inches; through the central belt from southwest to northeast it is thirty, and in the extreme northwestern section twenty-five inches. In the United States CLIMATOLOGY OF IOWA. 3F Army Meteorological Kegister, published iu 185o, Mr. Blodgot, referring to the precipitation in the Mississippi Valley, says : "There is an exceptional district in eastern Iowa having a great rain- fall, which requires some explanation, especially in its contrast with the- small quantities at Lake ^lichigan. The exception is due apparently to the elevation of central Missouri in comparison with lower Iowa, causing an atmospheric eddy similar to that of the lower Mississippi." A careful study of meteorological data covering the period since the above was published does not show so wide a difference between the average annual precipitation of the eastern, central and western districts of the State. For example, the average at Keokuk, from 1872 to 1892, is 35.87 inches; at Muscatine, 1845 to 1892, 39.21 inches; at Davenport, 1872 to 1892,, 34.70 inches; at Dubuque, 1874 to 1892, 37.00 inches; at i\IcGregor, 16 years record, 34.97 inches. These stations are all iu the eastern part of the State. and it will be seen the average is below the figures of Blodget's rain chart. In the central and western sections of the State, the following averages are obtained: Des Moines, 35.06 inches; Sioux City, 25.58 inches; Council Bluffs, 33.36 inches; Logan, 35.50 inches; Sac City, 30.82 inches; Glenwood, 31.70 inches. These figures indicate that there is a more equable distribu- tion of rainfall than the earlier charts aud tables showed. And it may be stated further that in the western half of the State the precipitation in the winter mouths is considerably less than in the eastern half, while the rain- fall iu the summer mouths is greater in the western than iu the eastern districts. COMPARISON WITH E.\STERN STATES. The annual precipitation in Iowa is equal to the averages in the- northern, central and western portions of New York, northern Vermont and New Hampshire, northwestern counties of Pennsylvania, northern Ohio and the larger part of jMichigau. In fact it compares favorably with all the- Atlantic and Middle States on the same latitude, except points along or near the sea coast, or in the mountainous districts. The folloAving yearly averages are from the United States Weather Bureau tables of recent date : STATION'S. INCHES. STATIONS. INCHES. Charlotte, Vt 33.79 Fort Niagara, X. Y 25.53 Hanover, N.

Y 31.73 Lansing, Midi 33.75 Comparison of these yearly averages with the accompanying tables of annual precipitation at a large number of Iowa stations will show that the eastern states on this parallel have no advantage over Iowa in respect to the yearly supply of moisture. And it will be seen that these figures do not sustain the theory that the annual precipitation of a locality is affected by contiguity to the lakes or extensive forests. In fact, local evaporation, whether from marshes, lakes. OT forests does not materially affect the rainfall of the interior of the con- j2 HAND BOOK OF IOWA. tinent. The following from the United States Army Meteorological Regis- ter is to the point : " The lake district presents a somewhat auomalons result, in compari- son Math the interior portions, as it has less rainfall than the valley of the Mississippi in their latitudes. The effect of these bodies of water is clearly to diminish the quantity of rain for the whole period of the warm season. This deliciency appears very clearly in the mean for the spring, and it is ■conclusive proof that local evaporation adds little or none to the quantity of rain of these interior districts. The valley of the Mississippi, and its exten- sion in the Ohio valley, strikingly contrast with the rainfall in the lake districts. DISTRIBUTION BY SEASONS. A peciiliar feature of the climate of the trans-Mississippi region is that it has its minimum of precipitation in the winter, and its maximum in the spring and summer, or in the crop growing season. This characteristic of the climate is of great economic importance, since it insures an abundance of food products even in years of the greatest variability in the distribution of moisture. In this respect Iowa has a most decided advantage over the eastern states which have a much heavier annual rainfall, for in this State two-thirds of the yearly moisture comes in the six crop growing mouths, when it is most needed. Professor Blodget, in his American Climatology, refers to this feature as follows : " For the whole period of the warm months, in which May and Sep- tember should be included, the quantity of rain distributed over the Mis- sissippi valley is comparatively very great, and there is no great area so far in the interior which presents a similar result. The quantities are abso- lutely as well as relatively large, and they considerably exceed those of the plains of the Atlantic coast in the same latitude. The line of fifteen inches for the three (summer) months goes only to 38 of latitude on the Atlantic coast, j^et it rises nearly to 44 in the ISIississippi valley, and occupies a very wide area below the fortieth parallel. The measure of twelve inches is equally more extensive in the interior, though neither of these stretches upon the plains beyond 100 west longitude." The fact here stated is undoubtedly due to the prevalence during the summer months of southerly winds laden with vapor from the Gulf, the great thermal fountain whence is drawn the bulk of the precipitation of the interior valleys. The following table gives, as a basis of comparison, the average rainfall for the four critical months of the year, viz: May, June, Jul}' and August, at a number of stations in the Atlantic states and in Iowa : EASTERN INCHFS ^^"'"''^ STATIONS. iiivnr,s.

The average rainfall of Iowa for the four mouths named is as follows : ]\Iay 4.15 inches; June 4.95; July 4.30; August JJ.OO. Total for the four months 17.00 inches. But let us take the si.x crop months, adding April and September to the four above named, and we have a total average rainfall of 28.25 inches, or an average of 3.87 inches per month. This amount of moisture in the soil, and a mean summer temperature of 71 degrees, give a hot-house development to the staple crops of this region. Dr. Gustavus Ilinrichs, w'ho originated the Iowa AVeather Service and served over twelve years as its director, said in his last annual report : "While low^a has a continental climate in regard to temperature, it enjoys the fertilizing advantages of a high and well distributed rainfall usually restricted to the coasts only. In fact there is no region in the interior of any continent that has a climate like that of Iowa, in which the extremes of temperature are coupled with an abundance of fertilizing moisture. Right close to the south, the immense boiler of the Gulf is furnishing vapor ; the heated continental expanse north causes the southerly current prevailing throughout the summer. These southerly winds carry the mois- ture of the Gulf all over the Mississippi valley, where it descends normally in great abundance, making it the best watered valley in the world." In Hall's Geology of Iowa the following statement occurs in the open- ing chapiter; " The most marked feature iif the distribution of moisture precipitated in the form of rain and snow through the year is a relative increase in the c^uantity falling in the spring and summer, and a very considerable dimunition in winter; which condition becomes more and more marked as we advance westward from the Mississippi. The dimunition in the quantity of snow, as compared with the eastern States on the same parallel, is one of the features of the climate which is practically most felt by settlers in that region." The climatic feature has a favorable effect upon the health and comfort of the inhabitants of this region, the relatively dry atmosphere enabling them to easily withstand the low temperature prevalent in the winter months. Those who have experienced the chilling atmosphere and "eternal drizzle" of the so-called milder climates of the sea coast region can appreciate the difference. CROPS IN DROUGHTY SEASONS. "While a high average of summer rainfall has been recorded for the past fifty years, this State like all other sections of the country is subject to fluctuations or variability in the seasonal precipitation, and occasional drouglity seasons have been experienced. But as a compensation there is a peculiar (juality of the Iowa soil which enables it to withstand droughts and produce abundantly with an average summer rainfall that would be totally insufficient in eastern and southern states. This fact was noted by Prof. T. S. Parvin some years ago, who in a contribution to the American Journal of Science, Vol. XXIII, said: " In 1854 occurred the great drought in this and the western States generally; but owing to the porous nature of our soil the crops with us turned out much better than in the States east of the Mississippi." 34 HAND BOOK OF IOWA. " 1856. This season was veiy dry; the total quantity of rain in the summei' months was only 6.78 inches, or 10.20 below the summer mean. The crops were, notwithstanding, more than an average J'ield, both of corn and small grain; and the three or four dry seasons we have had abundantly prove that the soil and climate of Iowa are unsurpassed on the continent for farming purposes." These facts so well stated bj- Prof. Parvin have been remarked in the occasional dry seasons that have occurred since'the above was written, justify- ing the assertion that there has never been any very near approach to absolute failure of crops in Iowa since its settlement by civilized man. And the years of severe drought in tlie summer months have been very few in comparison to the number suffered in some of tiie States which have a larger average annual rainfall. The severest drought in recent years, affecting the lower part of the State, occurred in the mid-summer of 1890. The average amount of rainfall in July was only 1.98 inches, and in August, 3.41 inches. And the severity of the drought was greatly increased by very high winds during the periods of high temperature. And yet in that year of untoward conditions, Iowa produced 239,000,000 bushels of corn, 71,368,000 bushels of oats, 2,979,081 bushels of flax, 8,332,000 bushels of potatoes, 4,991,000 tons of hay, and over $50,000,000 worth of poultry products. There is no danger of a famine in a countr}', which, in the worst seasons, can produce such vast amounts of food stuffs. The same porous nature of the soil which causes it to withstand severe droughts, also gives it the requisite quality to take up a considerable surplus of rainfall, making it fairly productive in abnormally wet seasons. These extremes, however, are exceptional, by far the greater number of years being normal and abundantly productive. The State is favorably situated in the heart of the valley, escaping frequent liability to the extremes of wet and dry to which other sections are subject. Prof. W. I. Chamberlain, of Ohio, who served about five years as president of the Iowa Agricultural College, gave the following unbiased testimony concerning the soil and climate of this state: " One thing has surprised me each spring and summer, viz: that the spring is considerably earlier here than it is a hundred miles further south in Ohio, and the summer is much hotter and surer to mature the corn crop before frost. Thq proportion of clear sky and hot days and nights is far greater, and the power of the sun's rays upon the black soil is immense. I believe Iowa to be on the whole the best and surest corn State in the Union, the surface is more rolling, the soil more porous and sandy and better drained by nature than most of the prairie soils in other States. Hence the corn is not so subject to damage from too much rain here as in Illinois and Missouri. It dries out for cultivation quicker."

On an average there are 140 to 150 days between the hitest damaging frost of spring and the first killing frost of autinnn. The latest of spring occnrs on an average, about the last week in April or the first week in May; and the earliest damaging frost of the fall is about the 25th of September. Light and comparatively harmless frosts occasionally occur between those dates, but as a rule there is in every season ample time to produce a well- matured crop of the best varieties of western dent corn, which with favor- itig- conditions may be grown iii 100 to 110 days after germination. Prof. Parvin's very complete records, covering the years from 1839 to 1869, show the mean dates to have been for the latest frost May 4, and for the earliest September 24. This would give an average exemption from hurtful frosts of 142 days. Prof. Parvin, writing in 1870 said: " It has happened but once or twice in the last thirty years that the frost has, over a great extent, seriously injured the corn crop. When the spring is late, the fall is either qnite hot or lengthened, so as to afford time for the crop to mature." This has been the result of observation in the years since this paragraph was written. A careful study of all available records leads to the con- clusion that Iowa has, on an average, as long a period of exemption from killing frosts in the crop season as any State within the same parallels of latitude in the eastern part of the United States, except possibly within a few miles of the coast. DESTRUCTIVE STORMS. In common with nearly all portions of the United States east of the Rocky Mountains, Iowa is subject to the occasional visitation of violent atmospheric disturbances, in form of wind-squalls, hail and thunder storms. The more destructive effects of these disturbances, however are purely local, and limited to small areas compared with the extent of territory benefitted by the storm. Being well watered, it cannot escape these almost universal conditions. The Gulf is the great thermal fountain of humidity, and the boreal regions send down the valley the titanic forces which wring fertilizing moisture from the vapor-laden winds of the south. The Gulf and the Arctic sea are the positive and negative poles of the battery which propels the alternating life currents through this favored region. And the earth is •watered and made fruitful by this conflict of elements, which at times becomes so intense and violent at local points as to cause destruction to life and property. But the more violent storms which occasionally sweep over small areas of the State are the incidental ills resulting from condilions ■which promote the general good. Ilail-storms, thunder storms, tornadoes and wind-squalls are the exceptional products of the benign elements of heat and moisture which make this valley a paradise of abundance. If the course of this great valley had been east and west instead of north and south, with the mountain ranges at right angles with their present direction, the interior of the continent would be exempt from atmospheric distur- bances of this character ; but it would be an uninhabitable desert instead of the garden of the world. There are regions of wide extent which enjoy 40 HAND BOOK OF IOWA. almost perfect immunity from the class of storms above referred to, but they are deserts or arid sections whicli must nerds be irrigated to yield even a scanty support to their inhabitants. The climate of this State, with all its drawbacks and incidental disturbances is vastly to be preferred to the deserts or semi-arid regions, notwithstanding their exemption from destructive storms. The reputation of Iowa's climate has been injured among people who are not well informed on the subject, by exaggerated descriptions of the occasional severe storms incident to this latitude ; and the idea has pre- vailed to some extent that this section is alternately plowed by tornadoes and harrowed by blizzards. This has resulted from the fact that newspaper reports of wind-storrus are often highly over-wrought, from indulgence in the American passion for sensationalism. And, unfortunately, some of these exaggerated reports have been embodied in ofHcial records to the detriment of the State. Using these highly colored newspaper reports as a basis, there was published a few years ago in the American Meteorological Journal, a so-called "Iowa Tornado Chart," giving the tracks of alleged tornadoes for the period of fifty-two years. The total number charged to the account of this State was 128, and the year of greatest frequency was 1886, which 3'ear was credited with a crop of twenty-six veritable tornadoes raised on Iowa soil. A careful investigation showed that the bulk of these disturbances were merely wind squalls accompanying thunder-storms of some local severity. The aggregate of damage from storms that year was very light. The tendency to exaggerate the importance or violence of local phenomena causes certain newspaper reporters to apply the term "cyclone" to every wind gust which is powerful enough to demolish some of the frail structures which were very common in this State in the pioneer era, and which are yet quite numerous. But the people who have resided in Iowa through good and evil report have learned that it is as safe as any other section within the temperate zone. And despite the exaggerated reports it may be positively affirmed that veritable tornadoes are quite infrequent in this State. Since its settlement by the whites, there have been in Iowa two notably destructive tornadoes which are entitled to rank with the great disturbances of like nature at Lawrence, Mass,, Reading, Pa., and Louisville, Ky. Dr. Gustavus Hinrichs, in his annual report of the Iowa Weather Ser- vice for the year 1888, published a very complete refutation of the exagger- ated statements that had been given currency relative to Iowa tornadoes. Gen. Greeh\ Chief Signal Officer, in his book on Ameiican Weather, sa5's that three thousand persons haye been killed in the United States by this class of storms, and the loss of life has been greatest in relative order in States as follow* : Missouri, Mississippi, Iowa, Illinois, Minnesota, Wis- consin and Ohio. The loss of property aggregates several millions, and has been fixed in round numbers, as follows : Ohio, over eight millions of dol- lars ; Minnesota, six millions ; Missouri, three millions ; Mississippi, two millions ; Iowa, one and a half millions ; Wisconsin, over one million. In his report for 1890, Gen. Greely gives a statement of the relation between the total area visited annually by violent storms of all classes to the area of the State, with the following result : In Alabama, one square m CLIHATOLOGY OF IOWA. 41 mile of limited destruction to each 8,800 square miles ; Arkansas, one to 14,418 ; Georgia, one to 0,090 ; Illinois, one to 8,103 ; Indiana, one to 0,210 ; Iowa, one to 7,164; Kansas, one to 9,730 ; Missoui'i, one to 5,336 ; Ohio, one to 4,554 ; AVisconsin, one to 12,042. Gen. Greely adds : " It appears that in no State may a destructive tornado be expected oftener, on an average, than once in two years, and the area over which the total destruction can be expected is exceedingly small, even in the States most liable to these violent storms." And he further concludes that, dangerous as are tornadoes, they are not so destructive to life as thunderstorms. This accords with observations in Iowa, as it is evident that, in the aggregate, verj'^ many more deaths have been caused by lightning strokes than bj' any class of wind-storms. WIND MOVEMENT. The State is sufficiently well ventilated to make it healthful. On an average the wind movement is ample to secure immunity from malaria and the germs of disease which arise from decaying vegetation, and to furnish mechanical power for the pumping of stock w'ater and the grinding of feed. The mean velocity of the wind over the State accords very closely with the average for the United States. The average hourly movement is 7 to 8 miles. At an early period, when the prairies were comparatively treeless, the effects of winds were more apparent than now, their force having been greatly modified in recent j'ears by artificial groves, hedges and timber belts. The prevailing winds are southerly in summer and westerly' at other seasons. IS THE CLIMATE PERMANENT ? All the recorded weather observations of the past fifty years answer affirmatively. In recent droughty seasons fears were expressed by certain writers that through tillage, ditching and tile drainage, and from the effects of clearing away extensive forests in the northwest, the climate of this portion of the Mississippi valley has been materially changed by decreasing the humiditj" and seasonal rainfall. But the records prove absolutely that there has been no dimunition in the humidity and rainfall within the last decade as compared with any preceding decade, nor within the last twenty years as compared with any preceding score of years since the States was settled by civilized people. There have been seasons of excess and of deficiency all along the line of recorded observations, but the shortage has been no more serious in the eighties and nineties than in the fifties and sixties. No, there has been no appreciable change in any essential feature of the climate. It is as stable as the everlasting hills, and as permanent as the inflow and outflow of the currents of the Gulf, by which it is so copiously watered. In concluding this chapter the writer desires to acknowledge his indebtedness to the Chief of the Weather Bureau for voluminous records relating to the climate of this State, and to Dr. Geo. >I. Chappel, Local Forecast Official and Assistant Director of the Iowa Weather and Crop Service, for very efficient aid in the arrangement and tabulation of meteor- ological data. 42 HAND BOOK OF IOWA. NATURAL RESOURCES. Nature gave to Iowa a better dowry than uiiues of diamonds or moun- taius stored with silver and gold. Its more valuable resources consist ia water, sands, rocks, coal and timber, and above all its deep, porous w^onder- ful soil. Gold, silver, nickle, zinc, iron, aluminum, and natural gas have been found ; but whether they exist in remunerative quantities is to be determined by future efforts for their development. WATER. We class water as one of the natural resources of this productive state. Go west — cross the continent to the Pacific — and you ask why those great deserts which you pass in your journey. They are desert because the rain- fall, the natural irrigation essential to vegetable production, is withheld. Here fructifying showers nourish, invigorate and perpetuate vegetable life. In the three score years of our written history no pen has ever written of Iowa's fields being made barren by burning drouth, or of her people suffer- ing the pangs of famine because the essential rainfall was withheld until crops were parched and starvation befell them. The beneficient Creator gave to Iowa a wealth of resources of more priceless value than mountains of the precious metals, in her ever duly recurring showers, and her numer- ous springs and perennial streams. MEDICINAL WATERS. We have valuable healing waters in Iowa. Streams flow from unfail- ing fountains that give strength to the weak, ease to the pain-ridden, and healing to the sick. We can speak only of a few of such fountains. The Lake View Mineral Spring — This is a natural spring near the western shore of Wall Lake, a body of water lying in Sac county and fur- nishing fine opportunities for boating, fishing and pleasure driving in its vicinity. Circumstances have led to the improvement of the surroundings of this healing fountain that has now wide reputation for the cure of many of the ills to which mortal nature is subject. We give the following analysis of its water made by Prof. Walter .J. Haines, of Rush ]\Iedical College August, 1888. Each gallon of 231 inches contains : GRAINS.

Some fifteen years ago an enterprising citizen surmising that a paying vein of coal lay hidden under the high wooded hill east of the village, procured a drilling apparatus and started the tools downward in quest of the desired treasure. By slow, laborioas process he put his drill down about four hundred and fifteen feet when a sudden bursting forth of a fine stream of water caused a stoppage of his work. lie was not i)leased with what he then considered ill luck, but his complaints interposed no check to the gushing stream. It continued its bright and abundant fiow. The workmen and spectators sipped thereof to investigate its quality. Its taste at first peculiar, after a little use was not unpleasant; those who drank freely, however, were soon admonished that it possessed unusual qualities, and a. quantity of the sparkling fluid was sent to an educated physician at Daven- port for examination. Acting on his recommendation a quantity was for- warded to Prof. Ileiurichs of the State University, who reported the follow- ing analysis of the fluid: GRAINS PER OALLON.

Their analysis varies but slightly from that above given. The "Colfax Springs" running "abundant, free and clear" are already of great value. Their healing virtues have been tested by thousands of visitors from our own and other states who came to them enfeebled by disease, but went from them with radiant cheek and buoyant step to proclaim their health restoring power. DES MOINES SIEDICIXAL W'ELLS. Several artesian flows of water have been struck in and near the city of Des Moines that are reputed to have medicinal value. The water from one in the central part of the city has been used quite extensively with great benefit to many persons. At Cherokee, Lineville and other places in the state there are water* reported to be of considerable medicinal value. THE CLINTON WELLS. The city of Clinton is finely supplied with pure health giving water, obtained from artesian wells, drilled into the Potsdam sandstone. Of the source and abundance of the supply, Superintendent llighiands of the city water works reports as follows : 44 HAND BOOK OF IOWA. " It might not be amiss in tiiis connection to say sometiiing about tlie source of this magnificent water supply. In this locality the Potsdam sand- stone is reached by the drill at 1,475 feet, or about 1,400 feet below low water line in the river and this is the source from which the water is derived. This stratum of sandstone is covered over with 1,100 feet of limestone and 300 to 500 feet of shale. The 400 to 500 feet of limestone immediately oyer the sandstone was broken up by some convulsion of nature and whenever the drill strikes one of these crevices the water will flow to the surface, with the same pressui-e, but with less volume, as if the drill had penetrated the sandstone. In drilling well No. 3 the drill penetrated three such crevices. The pressure of water from each of those crevices or apparent veins was carefully tested by packing off the water above them and it was found exactly the same as when tested at the depth of 1,600 feet. The fact that the water will only raise 68 feet above the river, shows conclusively that the water does not come from any point near the head waters of the Missis- sippi river, and it is also equally plain that it could not enter the ground on the line of the river where it is only 68 feet above us, for the reason that in so short a distance it could not have penetrated through the shale and lime- stone into the sandstone. The only alternative is that it must come from the Lake Superior region where the sandstone crops out." The difference in levels between this and Lake Superior would seem to bear out this opinion . Speaking of the city wells he says: "The rise and flow of our wells now are as follows : " No. 1, eight inch bore, 1,450 feet deep ; daily flow 700,000 gallons. "No. 2, five inch bore, 1,235 feet deep ; daily flow 400,000 gallons. " No. 3, eight inch bore, 1,675 feet deep ; daily flow 900,000 gallons." These three wells are drilled within a radius of 200 feet and the flow and pressure seem to remain constant. The city mains are connected with three other wells, one owned by the city of Lyons and the other by private parties, and the total supply at com- mand is thus stated: "Our mains are also connected with the pumping stations of the Lyons water works, W. J. Young & Co., and C. Lamb & Sous' Chancy mills. The total pumping capacity for fire protection is as follows : GALLONS PER DAY. Clinton station •J,()0(),000 Lyons station 3,000,000 W. J. Young & Co 6,000,000 C. Lamb & Sons 4,000,000 Total 22,000,000 "As our maximum daily consumption rarely reaches 2,500,000 gallons per day this would leave 19,500,000 gallons per day for fire protection, or water enough to supply eighty-one inch fire streams with 100 pounds of pressure through 400 feet of hose ; or if any one of the stations were dis- abled it would be very easy for the other three to afford adequate fire protection."

The largest one flows a large volume, the bore being put down 1,00s feet. The Potsdam stone here lies many hundred feet higher than the stratum lies at Clinton, the stratum cropping out at the former place. The water in the McGregor wells appears to be more highly medicinal than the Clinton water. We cannot give any reported measurement of the flow at McGregor, but the facts that we have given indicate that abundant supplies of the purest w^ater can be obtained in the cities along the Mississippi wherever the Potsdam sandstone can be reached. SOIL. Soil, sunlight and water are the great essentials to the production of the bread, meats and fruits that feed our race. Iowa has world-wide fame for the depth and richness, the mellowness and productive quality of her soil. Prof. White, in his report as State Geologist, speaking of the soil of Iowa said : "After careful consideration of the results of my examinations, I do not hesitate to thus publicly announce my estimate that 95 per cent, of the surface of Iowa is tillable land. The state being without mountain rani-es hills or other barren surfaces and everj^where covered with a soil of such fertility and depth, its agricultural capabilities are almost beyond computation." The theory of geologists that the soil of Iowa is formed largely of decomposed rocks floated over the portion of the State the drift covers, may be true or not. Its depth and productive qualities are the matters of our 46 HAND BOOK OF IOWA. chief couceru. There are but few places in this remarkably productive state where a plow can turn up barren subsoil; the fertile soil is found through the state ranging in depth from one to one hundred feet. This is more fully described in the chapter on the Geology of Iowa, by Prof. Keyes. One great advantage of our soil is its porousness. It is easily pulverized, is light and warm and the roots of growing crops easily penetrate it. This characteristic not only makes farm labor inviting on account of the crop produced, but doubly so by the ease with which the cultivation is done. We hear nothing in Iowa of soil being worn out. It cannot be "worn out with a,ny proper farming, hence there is wealth for the ages in its fertility and productive power, and there is perpetual comfort in the ease with which agricultural operations are performed. This species of earth is important in essential manufactures. The savage may build his wigwam frame of poles and cover it with grass or skins or barks. The pioneer will build his cabin of logs or sod, but by industry and economy he soon provides the means for better things. The brick maker and mason's services are soon needed and openings invite the pottery and the tile factor}^ and search is made for suitable claj's for these manufactures. In all parts of Iowa, clays suitable for the manufacture of excellent brick is easily obtained, hence the brick industry is obtaining large dimensions. The demand for building brick, paving brick and the finest ■quality of pressed brick is having yearly increase. The day of building cheap, perishable shanties for residences, and structures of cheap combustible and perishable material for business uses is outgrown in this State. Three to eight story solid, stately business blocks now grace our cities, and solid brick and stone residences are found in our numerous thrifty villages. Our cities and towns now mostly have their " fire limits," and the indulgence of a false economy in the erection of cheap, unattractive, combustible structures in our business centers is largely prohibited. This wise provision encourages improved architecture and the use of building material of substantial quality, and so the brick makers art is encouraged and his business enlarged. No better clays can be found for the manufacture of the finest quality of pressed brick than are now ob- tained in numerous places in this state. Superior clays for the manufacture of stoneware and finer forms of pottery are found in numerous places. During the year 1892 several hundred carloads of cla}"-, for the manufacture of tableware were shipped from Hardin county to Sheboygan, Wisconsin, Milwaukee and elsewhere. Tests of this clay have been made at Liverpool, Paris, and Wellsville, Ohio, Terre Haute, Indiana, Perth Amboy, N. Y., and elsewhere with most satis- factory results in the manufacture of white ware. Large deposits of this quality of clay are found. With the taking up of the wild lands and the consequent increased value of lands the demand for tile to drain springy, spouty places and waste sloughs is rapidl}^ increasing, and the manufacture of tile for drainage purposes has already assumed large proportions. Excellent clays for this manufacture are found throughout the state. NATURAL RESOURCES. 47 The settlement of the eoimtry with its iucreiisinij,- popuhition and wealth makes good roads more important and leads to road improvement. The growth of flourishing towns and cities, and care for their cleanliness and healthfulness provide enlarging markets for sewer pipe, and its manufacture is becoming an important and growing industry. According to slang phrase, is fi vjiluable quality in the mental consti- tution. It is an essential element in our industries. Many important mechanical and manufacturlDg operations demand its use. The people of Iowa have rich endowment of the mental element expressed by the term, and nature has provided numerous banks of this material in suitable quali- ties and quantities for mechanical operations. The builder readily finds suitable sand. The brick maker and iron moulder find sands suitable for their operations, while glass factories and smelting furnaces export sands in quantities from our state for their work. Iowa is not a mountainous nor rocky State, but the exact reverse. Yet there is abundant supply of stone for building, the manufacture of lime and other uses. The general distribution of railroads throughout the state, makes these supplies, that the Creator liberally provided, everywhere avail- able. Census bulletin No. 78, Census of 1890, devoted to Klines and Miniusr, treating of limestone, gives important figures respecting this important natural commoditv. The whole number of limestone ciuarries reported in the country was 1,954. Of these 148 were in Iowa. These Iowa (juarries had a reported value of $530,868. The product of these 143 quarries in this state was reported as 6,280,727 cubic feet of stone for building purposes, valued at $286,792. Lime burned 365.394 barrels of 200 pounds each, of the value of $170,043. For street work 1,732,630 cubic feet of the value of $70,887 were produced. These products of the 143 limestone quarries of Iowa, having a reported value of $477,222. Relatively among the states of the Union Iowa has fair rank in the production of this useful and valuable stone. In the number of lime- stone quarries having fifth place ; in the number of employees workino- such quarries seventh place ; in amoimt of wages paid tenth place ; in amount of stone produced, twelfth place ; and in the aggregate value of the product of limestone quarries tenth place. The limestone beds of Iowa are not found in one corner or in one locality of the State merely, but have quite general distribution over its area. A further description of the rocks of the State is given in this chapter by Prof. Keyes. GYPSUM. Is found in large deposits in Webster county, along the Des Moines river. All the operators in its production in 1889 had their headquarters at Fort Dodge. All the deposits or beds of gypsum being found near that city. To quite a large extent gypsum has been used in Fort Dodge for build- ing purposes. When first (luarried it is easily dressed with an axe or saw, 48 HAND BOOK OF IOWA. hardens when in the wall and makes a solid strncture. Prof. White, in his geographical report, wrote in 1870 of a residence built of this rock in 1861 : " Its walls appear as unaffected by exposure and as beautiful as they were when first erected." In the year named gypsum was i)roduced in California, Colorado, Iowa, Kansas, Michigan, New^ York, Ohio, South Dakota, Utah, Virginia and AVyoming. Iowa ranking third in the quantity produced and third in the total value of the product. In that year the industry at Fort Dodge gave employment to 59 men. Part of the product is sold and used as a fertilizer, 14,434 short tons of the Iowa product being sold in 1889 for that purpose 7,550 tons were calcined for stucco. The product of the mines and factories that year in Iowa was valued at $55,250. The deposits are found in the bluffs of the Des Moines river, covering an extent of about seven miles along the river valley. Prof. White gives the thickness of the deposit at Goss' Mill, then its known southern extremity, as ten feet. At the Cummins quarry, six miles northward from the Goss Mill, as twenty feet. The deposit is sufficiently large to be virtually inexhaustible, but is formed in somewhat irregular layers. Prof. White pronounces it of "as good qualitj^ as any in the coun- try, even for the finest uses." Iowa gypsum manufactured into stucco, was very largely used in the manufacture of "staff," the material used for the external covering of the exhibition buildings in Jackson Park. COAL. The coal product of the country is of the utmost importance to the public prosperity. While this statement is true in regard to the,- whole countrj' it is energized when we apply it particularly to a prairie State. Iowa may not be far known as a mining State, yetthe productions of her mines are no mean interest. Few suppose that she has place in the list of States near to the top in any mining production. But she has high rank in the production of bituminous coal. The United States census of 1890 reports twenty-seven coal producing States and their entire production as 95,729,026 tons. It reports the following five States as producing for the j'ear 1889, the amounts given below, they being the five leading States : STATES. PRODUCTION. Pennsylvania 36,174,089 tons Illinois 12,104,272 " Ohio 9,976,787 " West Virginia 6,231,890 " Iowa 6,095,358 " Iowa ranges tenth in population but fifth in the production of bitumi- nous coal, producing in 1890 one bushel in every twenty-two bushels of the product of the country. The state mine inspectors in their last biennial report to the governor of the State, report production of coal in twenty-three counties. The State has three raining districts. We copy tables given by the several inspectors showing the number of mines, production and other interesting items rela ting to this business in each county named : NATURAL RESOURCES. 49 Showing number of mines, annual output, number of miners and other employe:^, value of product, etc., in District ^»o. 1, for the year ending June 30, 18'Jl.
