The violent attack upon this duty and the very plausible reasons for believing that the industry could never be selfsupporting, led to the adopting of an ingenious provision, limiting the time that manufacturers might have to establish the business. Tin plate was to be admitted free of duty after October 1, 1897, unless in some one of the years between 1891 (when the duty was to go into effect) and 1897, one-third as much tin plate was produced here as was imported in any one of the other six years. This clever device originated with Senator Spooner of Wisconsin. The Tin Plate and Iron and Steel Associations practically wrote their own schedules in the McKinley Bill. The wool growers and woollen manufacturers did the same. A series of poor years in wool occurred in the ’80’s. There were legitimate causes outside of the tariff for the depression, but a large and influential part of the industry believed or professed to believe the trouble to come solely from reductions in duties made in 1883. These reductions had disturbed the “harmony” in wool which they claimed the growers and manufacturers had established in 1867, and which they now loudly affirmed must be restored if the two branches of the industry were again to be prosperous. There were long petitions presented by manufacturers asking for free wool, arguing that the industry could never hope to compete until it was on an equal footing with other nations in the matter of raw materials; but this point of view was not supported by the National Association of Wool Manufacturers, which by this time had become one of the most powerful political organizations in American industry. It held that the manufacturer must support the duty on wool if he did not wish to set the growers against the duty on woollens. It had been established in 1867 “almost as economic law,” Mr. Whitman, the president of the organization claimed, that the wool-grower was to have his duty, and that the wool manufacturer was to be given two kinds of duties, one which would compensate him fully for the tariffs on his raw materials, not only wool but dyestuffs, and that after that, he was to have the same measure of protection that other industries received. Mr. Whitman claimed that the lowering of the compensating duty in 1883 had particularly disturbed the “economic law.” As we have seen, this duty had been dropped from 50 to 35 cents. In making this drop the Committee had decided that it was a mistake to count 4 pounds of grease wool to one pound of cloth as had been done in 1867, since 4 pounds were rarely used. It had said that 3½ pounds was a generous allowance—as it was. Mr. Whitman remonstrated against this decreased compensation. He wanted the duty based on the 4 pounds and he wanted other upward revisions. The program proposed by the Association was practically adopted. It contained one curious provision new to the wool schedule and important in the later history of the
