America's Crop Heritage one-third to one-fourth of the annual appropriation for agriculture was being spent at this time for the distribution of seeds and plants. WORK OF COMMISSIONER LE DUC General William Le Duc of Minnesota succeeded Watts in 1877 and served until June, 1881. A former salesman, lawyer, and land promoter, Le Duc proved an able administrator whose work won the favorable attention of Congress and of the public. His reports stressed two themes: the introduction, experimentation, and pro- motion of sugar-producing plants, and the need for more funds and facilities for testing new plant introductions. His promotion of sugar is discussed topically in Chapter 7. During Le Duc's term, many plants were propagated and sent to localities where they might flourish. Buildings for and plant- ings of various fruit trees had taken most of the land available for experiment by 1878. Le Duc recommended the purchase of a thousand acres near Washington and the establishment of eight or ten experiment stations in different climatic and geographical regions. He enthusiastically promoted tropical and semitropical crops including tea, coffee, oranges, lemons, olives, Japanese per- simmons, bananas, pineapples, cacao, tamarind, cinchona, pepper, ginger, and dates. Scions of Russian apple trees and plants of European wine grapes were distributed. Le Duc was in turn critical of the extensive seed distributions by his predecessor. He planned to favor agricultural societies over other applicants, and devoted much space to criticism of distri- butions by members of Congress. Le Duc's views were endorsed by resolutions of farmers' organizations, by newspaper editors, by some members of Congress, and individual citizens. Le Duc's interest in tropical and semitropical products was reflected in his unusually large distributions of such plants. He claimed that large increases in yields valued at millions of dollars had resulted from his efforts, and he also believed that more diversification had been achieved. The appropriation act of 1881 required that "three-fourths of plants, seeds, and cuttings" should be made available to members of Congress for distribution. The proportion thus reserved varied from year to year, but had increased to five-sixths when the distributions were discontinued in 1923.
