ILLINOIS  , a See also:

North Central See also:state of the See also:United States of See also:America, situated between 37° and 42° 30' N. See also:lat. and 87° 35' and 91° 4o' W. See also:long . It is bounded N. by See also:Wisconsin, E. by See also:Lake See also:Michigan and See also:Indiana, S.E. and S. by the See also:Ohio See also:river, which separates it from See also:Kentucky, and S.W. and W. by the See also:Mississippi river, which separates it from See also:Missouri and See also:Iowa . The Enabling See also:Act of See also:Congress, which provided for the organization of Illinois Territory into a state, extended its See also:jurisdiction to the See also:middle of Lake Michigan and the Mississippi river; consequently the See also:total See also:area of the state is 58,329 sq. m., of which 2337 sq. m. are See also:water See also:surface, though the See also:official figures of the United States See also:Geological Survey, which does not take into See also:account this See also:extension of jurisdiction, are 56,665 sq. m . Pltysiography.—Physiographically, the state (except the extreme See also:southern point) lies wholly in the See also:Prairie Plains region . The N.E. corner is by some placed in the " See also:Great Lakes See also:District." The southern point touches the Coastal See also:Plain See also:Belt at its northward extension called the " Mississippi Embayment." The surface of Illinois is an inclined See also:plane, whose See also:general slope is toward the S. and S.W . The See also:average See also:elevation above See also:sea-level is about 600 ft.; the highest elevation is See also:Charles See also:Mound (1257 ft.), on the Illinois-\Wiscor.,See also:sin boundary See also:line, one of a See also:chain of hills that crosses Jo Daviess, See also:Stephenson, See also:Winnebago, See also:Boone and McHenry counties . An elevation from 6 to 10 m. wide crosses the southern See also:part of the state from See also:Grand See also:Tower, in See also:Jackson See also:county, on the Mississippi to Shawneetown, in See also:Gallatin county, on the Ohio, the highest point being 1047 ft. above the sea; from Grand Tower N. along the Mississippi to the mouth of the Illinois there is a slight elevation and there is another elevation of See also:minor importance along the See also:Wabash . Many of the river bluffs rise to an unusual height, Starved See also:Rock, near See also:Ottawa, in La Salle county, being 150 ft. above the See also:bed of the Illinois river . See also:Cave in Rock, on the Ohio, in Hardin county, was once the resort of river pirates . The See also:country S. of the elevation (mentioned above) between Grand Tower and Shawneetown was originally covered with forests . The drainage of Illinois is far better than its See also:low elevation and comparatively level surface would suggest . There are more than 275 streams in the state, grouped in two river systems, one having the Mississippi, which receives three-fourths of the See also:waters of Illinois, as outlet, the other being tributary to the Wabash or Ohio See also:rivers .

The most important river is the Illinois, which, formed by the junction of the See also:

Des Plaines and the See also:Kankakee, in the N.E. part of See also:Grundy county, crosses the N. central and W. portions ofthe state, draining 24,726 sq. m . At some points, notably at Lake See also:Peoria, it broadens into vast expanses resembling lakes . The Kaskaskia, in the S., notable for its See also:variations in See also:volume, and the See also:Kock, in the N., are the other important rivers emptying into the Mississippi; the Embarrass and Little Wabash, the Saline and Cache in the E., are the important tributaries of the Wabash and Ohio rivers . The See also:Chicago river, a See also:short stream i m. long, formed by the See also:union of its N. and S. branches, naturally flowed into Lake Michigan, but by the construction of the Chicago Drainage See also:Canal its waters were turned in 1900 so that they ultimately flow into the Mississippi . The See also:soil of Illinois is remarkable for its fertility . The surface soils are composed of See also:drift deposits, varying from io to 200 ft. in See also:depth; they are often overlaid with a See also:black See also:loam to to 15 in. deep, and in a large portion of the state there is a subsoil of yellow See also:clay . The soil of the prairies is darker and coarser than that of the forests, but all See also:differences disappear with cultivation . The soil of the river valleys is alluvial and especially fertile, the " See also:American Bottom," extending along the Mississippi from See also:Alton to See also:Chester, having been in cultivation for more than 150 years . Along the river bluffs there is a silicious See also:deposit called See also:loess, which is well suited to the cultivation of fruits and vegetables . In general the N. part of the state is especially suited to the cultivation of See also:hay, the N. and central parts to See also:Indian See also:corn, the E. to oats, and the S.W. to See also:wheat . See also:Climate.—The climate of Illinois is notable for its extremes of temperature . The warm winds which sweep up the Mississippi Valley from the Gulf of See also:Mexico are responsible for the extremes of See also:heat, and the See also:Arctic winds of the north, which find no See also:mountain range to break their strength, cause the extremes of See also:cold .

The mean See also:

annual temperature at Winnebago, near the N. border, is 470 F., and it increases to the southward at the See also:rate of about 2° for every degree of See also:latitude, being 52° F. at See also:Springfield, and 58° F. in See also:Cairo, at the S. extremity . The lowest temperature ever recorded in the state was -32° F., in See also:February 1905, at See also:Ashton in the N.W. and the highest was 115° F., in See also:July 1g01, at See also:Centralia, in the S., making a maximum range of 147° F . The range of extremes is considerably greater in the N. than in the S.; for example, at Winnebago extremes have ranged from -26° F. to 11o° F. or 136° F., but at Cairo they have ranged only from -16° F. to io6° F. or 122° F . The mean annual precipitation is about 39 in. in the S. counties, but this decreases to the northward, being about 36 in. in the central counties and 34 in. along the N. border . The mean annual See also:snow-fall increases from 12 in. at the S. extremity to approximately 40 in. in the N. counties . In the N. the precipitation is 44.8 % greater in See also:spring and summer than it is in autumn and See also:winter, but in the S. only 26.17% greater . At Cairo the prevailing winds are southerly duringall months except February, and as far north as Springfield they are southerly from See also:April to See also:January; but throughout the N. See also:half of the state, except along the See also:shore of Lake Michigan, where they vary from N.E. to S.W., the winds are mostly from the W. or N.W. from See also:October to See also:March and very variable for the See also:remainder of the See also:year . The dampness and miasma, to which so many of the See also:early settlers' fatal " chills and See also:fever " were due, have practically disappeared before See also:modern methods of sanitary drainage . See also:Fauna and See also:Flora.—The fauna and flora, which are similar to those of the other North Central States of North America, impressed the early explorers with their richness and variety . " We have seen nothing like this for the fertility of the See also:land, its prairies, See also:woods, and See also:wild See also:cattle," wrote Pere Jacques See also:Marquette of the Illinois region, and later explorers also See also:bore See also:witness to the richness of the country . Many of the See also:original wild animals, such as the bison, See also:bear, See also:beaver, See also:deer and See also:lynx, have disappeared; wolves, foxes and See also:mink are rare; but rabbits, squirrels and raccoons are still See also:common . The See also:fish are mainly the coarser See also:species, such as See also:carp, See also:buffalo-fish and See also:white See also:perch ; of better See also:food fish, the See also:principal varieties are See also:bass (black, striped and rock), crappie, See also:pike, " See also:jack See also:salmon " or See also:wall-eyed pike, and See also:sun fish .

The yield of the See also:

fisheries in 1900 was valued at $388,876 . The most important fisheries on the Illinois river and its tributaries were at See also:Havana, See also:Pekin and Peoria, which in 1907–1908 were represented by a total catch of about io,000,000 lb, out of a total for this river See also:system of 17,570,000 lb . The flora is varied . Great See also:numbers of See also:grasses and flowering See also:plants which once beautified the prairie landscape are still found on uncultivated lands, and there are about 8o species of trees, of which the See also:oak, See also:hickory, See also:maple and ash are the most common . The See also:cypress is found only in the S. and the tamarack only in the N . The See also:forest area, estimated• at 10,200 sq. m. in 1900, is almost wholly in the southern counties, and nearly all the trees which the See also:northern half of the state had before the coming of the whites were along the See also:banks of streams . Among wild fruits are the See also:cherry, See also:plum, See also:grape, See also:strawberry, black-See also:berry and See also:raspberry . See also:Industry and See also:Commerce.—The fertility of the soil, the See also:mineral See also:wealth and the transportation facilities have given Illinois a vast economic development . In 'goo more than seven-tenths of the inhabitants in gainful occupations were engaged in See also:agriculture (25.6%), • manufactures and See also:mechanical pursuits (26.7%), and See also:trade and transportation (22%) . Historically and comparatively, agriculture is the most important industry . In 1900 about nine-tenths of the total land area was inclosed in farms; the value of See also:farm See also:property ($2,004,316,897) was greater than that of any other state; as regards the total value of farm products in 1899 Illinois was surpassed only by Iowa; in the value of crops Illinois led all the states, and the values of property and of products were respectively 35-6% and 87.1% greater than at the end of the preceding See also:decade . During the last half of the 19th See also:century the number of farms increased rapidly, and the, average See also:size declined from 158 acres in 185o to 127.6 acres in 1870 and 124.2 acres in 1900 .

The prevailing See also:

form of See also:tenure is that of owners, 60.7% of the farms being so operated in 1900; but during the decade 189o-1900 the number of farms cultivated by See also:cash tenants in-creased 30.8%, and the number by See also:share tenants 24'5%, while the increase of cultivation by owners was only 1% . In proportion of farm land improved (84.5 %), Illinois was surpassed only by Iowa among the states . Cereals form the most important agricultural product (600,107,378 bushels in 1899—in value about three-fourths of the total agricultural products of the state) . In the See also:production of cereals Illinois surpassed the other states at the See also:close of each decade during the last half of the 19th century except that ending in 189o, when Iowa was the leading state . Indian corn and oats are the most valuable crops . The See also:rank of Illinois in the production of Indian corn was first in 1899 with about one-fifth of the total product of the United States, and first in 1907 I with nearly one-tenth of the total See also:crop of the country (9,521,000 bushels out of 99,931,000) . In 1879, in 1899 and in 1905 (when it produced 132,779,762 bushels out of 953,216,197 from the entire country) it was first among the states producing oats, but it was surpassed by Iowa in 1889, 1906 and 1907; in 1907 the Illinois crop was 101,675,000 bushels . From 1850 until 1879 Illinois also led in the production of wheat; the competition of the more western states, however, caused a great decline in both acreage and production of that cereal, the state's rank in the number of bushels produced declining to third in 1889 and to fourteenth in 1899, but the crop and yield per See also:acre in 1902 was larger than any since 1894; in 1905 the state ranked ninth, in 1906 eighth and in 1907 fifth (the crop being 40,104,000 bushels) among the wheat-growing states of the country . The rank of the state in the growing of See also:rye also declined from second in 1879 to eighth in 1899 and to ninth in 1907 (when the crop was 1,106,000 bushels), and the rank in the growing of See also:barley from third in 1869 to sixteenth in 1899 . In 1907 the barley crop was 600,000 bushels . Hay and See also:forage are, after cereals, the most important crops; in 1907 2,664,000 acres produced 3,730,000 tons of hay valued at 841,030,000 . Potatoes and See also:broom corn are other valuable products .

The See also:

potato crop in 1907 was 13,398,000 bushels, valued at $9,647,000, and the See also:sugar See also:beet, first introduced during the last decade of the 19th century, gave promise of becoming one of the most important crops . From 1889 to 1899 there was a distinct decline in the production of apples and peaches, but there was a great increase in that of cherries, plums and See also:pears . The large See also:urban See also:population of the state makes the See also:animal products very valuable, Illinois ranking third in 1900 in the number of See also:dairy cows, and in the farm value of dairy products; indeed, all classes of live stock, except See also:sheep, increased in number from 185o to 1900, and at the end of the latter year Illinois was surpassed only by Iowa in the number of horses and See also:swine; in 1909 there were more horses in Illinois than in Iowa . Important influences in the agricultural development of the state have been the formation of Farmers' Institutes, organized in 1895, a Corn Breeders' Association in 1898, and the introduction of fertilizers, the use of which in 1899 was nearly seven times the amount in 1889, and the study of soils, carried on by the State See also:Department of Agriculture and the United States Department of Agriculture . The growth of manufacturing in Illinois during the last half of the 19th century, due largely to the development of her exceptional transportation facilities, was the most rapid and remarkable in the See also:industrial See also:history of the United States . In 185o the state ranked fifteenth, in 1860 eighth, in 187o See also:sixth, in 188o See also:fourth, in 1890 and again in 1900 third, in the value of its manufactures . The average increases of invested See also:capital and products for each decade from 1850-19oo' were, respectively, 189.26% and 152.9%; in 1900 the capital invested ($776,829,598, of which $732,829,771 was in establishments under the factory system "), and the product ($1,259,730,168, of which $1,120,868,308 was from establishments under the " factory system "). showed unusually small percentages of increase over those for 1890 (54.7% and 38.6% respectively); and in 1905 the capital and product of establishments under the " factory system" were respectively $975,844,799 and $1,410,342,129, showing increases of 33.2% and 25.8% over the corresponding figures for 1900 . The most important industry was the wholesale slaughtering and packing of meats, which yielded 229% of the total manufactured product of the state in 1900, and 22.5% of the total in i The See also:statistics for years See also:prior to 1900 are taken from reports of the U.S . See also:Census, those for years after 1900 from the Year Books of the U.S . Department of Agriculture . It should be See also:borne in mind that in census years, when comparison can be made, the two sets of statistics often vary considerably.1905 . From 187o to 1905 Illinois surpassed the other states in this industry, yielding in 1900 and in 1905 more than one-third of the total product of the United States .

The increase in the value of the product in this industry in Illinois between 1900 and 1905 was over 1o% . An interesting phase of the industry is the secondary enterprises that have See also:

developed from it, nearly all portions of the slaughtered animal being finally put to use . The See also:blood is converted into clarifying material, the entrails are used for sausage coverings, the hoofs and small bones furnish the raw material for the manufacture of See also:glue, the large bones are carved into See also:knife handles, and the horns into combs, the fats are made to yield butterine, See also:lard and See also:soap, and the hides and See also:hair arc used in the manufacture of See also:mat-tresses and felts . The manufacture of See also:iron and See also:steel products, and of products depending upon iron and steel as raw material, is second in importance . The iron for these See also:industries is secured from the Lake See also:Superior region, the See also:coal and See also:limestone from mines within the state . Indeed, in the manufacture of iron and steel, Illinois was surpassed in 1900 only by See also:Pennsylvania and Ohio, the 1900 product being valued at $60,303,144; but the value of foundry and See also:machine See also:shop products was even greater ($63,878,352)• In 1905 the iron and steel product had increased in value since 1900 44'9%, to $87,352,761; the foundry and machine shop products 25.2%, to $79,961,482; and the See also:wire product showed even greater increase, largely because of a difference of See also:classification in the two censuses, the value in 1905 being $14,099,566, as against $2,879,188 in 1900, showing an increase of nearly 390% . The development of agriculture, by creating a demand for improved farm machinery, has stimulated the inventive See also:genius; in many cases blacksmith shops have been transformed into machinery factories; also well-established companies of the eastern states have been induced to remove to Illinois by the low prices of iron and See also:wood, due to cheap transportation rates on the Great Lakes . Consequently, in 1890, in 1900 and again in 1905, Illinois surpassed any one of the other states in the production of agricultural implements, the product in 1900 being valued at $42,033,796, or 41'5% of the total output of agricultural machinery in the United States; and in 1905 with a value of $38,412,452 it represented 34.3% of the product of the entire country . In the See also:building of railway cars by manufacturing corporations, Illinois also led the states in 1900 and in 1905, the product being valued at $24,845,606 in 1900 and at $30,926,464 (an increase of nearly one-fourth) in 1905; and in construction by railway companies was second in 1900, with a product valued at $16,580,424, which had increased 53.7 % in 1905, when the product was valued at $25,491,209 . The greatest increase of products between 1890 and 1900 was in the manufacture of See also:electrical apparatus (2400%), in which the increase in value of product was 37.2% between 1900 and 1905 . Another class of manufactures consists of those dependent upon agricultural products for raw material . Of these, the manufacture of distilled liquors was in 1900 and in 1905 the most important, Illinois leading the other states; the value of the 1900 product, which was nearly 12% less than that of 189o, was increased by 41.6%, to $54,101,805, in 1905 .

Pecria, the centre of the industry, is the largest producer of See also:

whisky and high-class wines of the cities in the United States . There were also, in 1900, 35 See also:direct and other indirect products made from Indian corn by See also:glucose plants, which consumed one-fifth of the Indian corn product of the state, and the value of these products was 818,122,814; in 1905 it was only $14,532,180 . Of other manufactures dependent upon agriculture, See also:flour and grist See also:mill products declined between 1890 and 1900, but between 1900 and 1905 increased 39.6% to a value of $39,892,127 . The manufacture of See also:cheese, See also:butter and condensed See also:milk increased 6o % between r890 and 1900, but between 1900 and 1905 only 3.1 %, the product in 1905 being valued at $13,276,533 . Other prosperous industries are the manufacture of See also:lumber and See also:timber products (the raw material being floated down the Mississippi river from the forests of other states), whose output increased from 1890 to 1900 nearly 50%, but declined slightly between 1900 and 1905; of See also:furniture ($22,131,846 in 1905; $15,285,475 in 1900; showing an increase of 44.8%), and of musical See also:instruments ($13,323,358 in 1905; $8,156,445 in 1900; an increase of 63.3% in the See also:period), in both of which Illinois was second in 1900 and in 1905; See also:book and See also:job See also:printing, in which the state ranked second in 1900 ($28,293,684 in 1905; $19,761,780 in 1900; an increase of 43.2%), newspaper and periodical printing ($28,644,981 in 1905; $19,404,955 in 1900; an increase of 47.6%), in which it ranked' third in 1900; and the manufacture of clothing, boots and shoes . The value of the clothing manufactured in 1905 was $67,439,617 (men's $55,202,999; See also:women's 812,236,618), an increase of 30.1% over 1900) . The great manufacturing centre is Chicago, where more than seven-tenths of the manufactured products of the state were produced in 1900, and more than two-thirds in 1905 . In this development of manufactures, the mineral resources have been an important See also:influence, nearly one-fourth (23.6%) of the manufactured product in 1900 depending upon minerals for raw material . Although the iron ore, for the iron and steel industry, is furnished by the mines of the Lake Superior region, bituminous coal and limestone are supplied by the Illinois deposits . The great ' central coal See also:field of North America extends into Illinois frnm 306 Indiana as far N. as a line from the N. boundary of Grundy county to Rock See also:Island, W. from Rock Island to See also:Henderson county, then S.W. to the southern part of Jackson county, when it runs S. into Kentucky, thus including more than three-fourths (42,900 sq. m.) of the land surface of the state . In 1679 Hennepin reported deposits of coal near what is now Ottawa on the Illinois; there was some See also:mining in 1810 on the Big Muddy river in Jackson county; and in 1833, 6000 tons were See also:mined . In 1907 (according to state authorities) coal was produced in 52 counties, See also:Williamson, Sangamon, St Clair, Macoupin and See also:Madison giving the largest yield .

In that year the See also:

tonnage was 51,317,146, and the value of the total product $54,687,882; in 1908 the value of the state's product of coal was exceeded only by that of Pennsylvania (nearly six times as great) . Nearly 30% of all coal mined in the state was mined by machinery in 1907 . The output of See also:petroleum in Illinois was long unimportant . The first serious attempts to find oil and See also:gas in the state were in the 'fifties of the 19th century . In 1889 the yield of petroleum was 146o barrels . In 1902 it was only 200 barrels, nearly all of which came from See also:Litchfield, See also:Montgomery county (where oil had been found in commercial quantities in 1886), and See also:Washington, Tazewell county, in the See also:west central part of the state; at this See also:time it was used locally for lubricating purposes . There had been some drilling in See also:Clark county in 1865, and in 1904 this field was again worked at See also:Westfield . In 1905 the total output of the state was 181,084 barrels; in 1906 the amount increased to 4,397,050 barrels, valued at $3,274,818; and in 1907, according to state reports, the output was 24,281,973 barrels, being nearly as great as that of the Appalachian field . The petroleum-producing area of commercial importance is a See also:strip of land about 8o m. long and 2 or 3 to 10 or 12 M. wide in the S.E. part of the state, centring about See also:Crawford county . In April 1906 the first See also:pipe lines for petroleum in Illinois were laid; before that time all shipments had been in tank cars . In connexion with petroleum, natural gas has been found, especially in Clark and Crawford counties; in 1906 the state's product of natural gas was valued at $87,211 . Limestone is found in about 30 counties, principally See also:Cook, Will and Kankakee; the value of the product in 1906 was $2,942,331 .

Clay and clay products of the state were valued in 1906 at $12,765,453 . Deposits of See also:

lead and See also:zinc have been discovered and worked in Jo Daviess county, near See also:Galena and See also:Elizabeth, in the N.W. part of the state . A southern district, including parts of Hardin, See also:Pope and Saline counties, has produced, incidentally to fluorspar, some lead, the maximum amount being 176,387 lb from the Fairview mine in 1866-1867 . In 1905 the zinc from the entire state was valued at $5,499,508; the lead See also:pro-duct in 1906 was valued at $65,208 . See also:Sandstone, quarried in to counties, was valued in 1905 at $29,115 and in 1906 at $19,125 . Pope and Hardin counties were the only See also:sources of fluorspar in the United States from 1842 until 1898, when fluorspar began to be mined in Kentucky; in 1906 the output was 28,268 tons, valued at $160,623, and in 1905 33,275 tons, valued at $220,206 . The centre of the fluorspar district was Rosiclare in Hardin county . The See also:cement deposits are also of value, natural cement being valued at $228,22I and See also:Portland cement at $2,461,494 in 1906 . Iron ore has been discovered . See also:Glass See also:sand is obtained from the Illinois river valley in La Salle county; in 1906 it was valued at $156,684, making the state in this product second only to Pennsylvania and West See also:Virginia (in 1905 it was second only to Pennsylvania) . The value of the total mineral product of the state in 1906 was estimated at $121,188,306.1 Communications.—Transportation facilities have been an important See also:factor in the economic development of Illinois . The first See also:European settlers, who were See also:French, came by way of the Great Lakes, and established intimate relations with New See also:Orleans by the Mississippi river .

The American settlers came by way of the Ohio river, and the immigrants from the New See also:

England and Eastern states found their way to Illinois over the See also:Erie Canal and the Great Lakes .
