Bonanza Years THE CLOSE of the nineteenth century found America's agricul- tural frontiers spread beyond the Rocky Mountains, north to the Canadian border and south to the Rio Grande. Farmers who had overworked their land by producing the same staple crops year after year could no longer pull up stakes and seek a new home- stead. Their incomes were decreasing as surpluses of the staple crops piled up. The Spanish-American war had created a wave of interest in tropical agriculture and consumers began to demand more varied diets. Millions of dollars went each year into agri- cultural imports. The economic development of many agricul- tural areas awaited the discovery of crops which could be grown successfully in a variety of climatic and soil conditions. Faced with the shortage of arable land and the food demands of an increasing population, farmers had an incentive to cultivate their soil with greater care. GOVERNMENT ASSISTANCE The government sought to relieve the plight of agriculture by putting crop production on a more efficient basis. One of the first steps in this work was a program making plant introductions systematic and scientific. The Department of Agriculture began to provide many new services to farmers, and a group of scientists and explorers was employed to begin the introduction of an enormous quantity of valuable plants. During the first term of James Wilson as Secretary of Agriculture, an appropriation of $20,000 was allowed for this work.' This federal aid in 1897 was S... That twenty thousand dollars of the sum thus appropriated . .may be used to collect, purchase, test, propagate, and distribute rare and valuable seeds, bulbs, trees, shrubs, vines, cuttings, and plants from foreign countries for experi- ments with reference to their introduction into this country; and the seeds, bulbs, trees, shrubs, vines, cuttings, and plants thus collected, purchased, tested, and propagated shall not be included in general distribution, but shall be used for experimental tests, to be carried on with the cooperation of the agricultural ex- periment stations.
