produced 3,730,000 tons of hay valued at $41,030,000. Potatoes and broom corn are other valuable products. The potato crop in 1907 was 13,398,000 bushels, valued at $9,647,000, and the sugar 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 pears. The large urban population of the state makes the animal products very valuable, Illinois ranking third in 1900 in the number of dairy cows, and in the farm value of dairy products; indeed, all classes of live stock, except sheep, increased in number from 1850 to 1900, and at the end of the latter year Illinois was surpassed only by Iowa in the number of horses and 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 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 industrial history of the United States. In 1850 the state ranked fifteenth, in 1860 eighth, in 1870 sixth, in 1880 fourth, in 1890 and again in 1900 third, in the value of its manufactures. The average increases of invested capital and products for each decade from 1850-1900 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.
