Main Importations By 1871 the problems of growing cinchona in this country were well known. It was sensitive to cold and required winter pro- tection, except in southern California where cultivation was carried on for more than a generation. Despite these difficulties many requests for the plants were received. A medical association memorialized Congress in 1872 urging the introduction of cin- chona. But William Le Duc discouraged further attempts to grow cinchona, and in 1877 stopped the distribution of the plants. Congress was repeatedly asked for money for further experi- ments with the cinchona plant. The House of Representatives passed a resolution in 1882 asking the Commissioner of Agri- culture whether it was feasible to grow cinchona in the United States. A letter from a plant authority alleged that the trees would stand frost, but needed exacting conditions of soil and climate. The Department had no faith in the new plant, but continued the experiments to satisfy an unwise demand and give the trees an exhaustive trial. By 1891, the cultivation of cinchona had been abandoned as unprofitable, for the bark could be imported cheaply from British India. TEA The records of the Department of Agriculture covering tea culture in the middle of the nineteenth century are rather sketchy. Either Isaac Newton's interests during this period did not extend to the promotion of the tea industry, or the war between the states prevented contact with the southern planters. During his commissionership the Department merely supplied requests for plants. Tea culture in British India was watched with interest, and labor-saving devices adopted there encouraged the belief that tea might be profitable in the United States. Fresh supplies of seed from Japan led to the distribution of more thousands of plants up to 1867. After this date, the plants were grown mostly from seed produced in the southern states, from the plants sent there by Robert Fortune. Horace Capron, Newton's successor, knew that the southern states were congenial to the tea plant, but he observed that ". .the amount of manual labor required in its preparation for commerce precludes the possibility of competition with the very cheap labor of China."
