The Committee early proceeded to hold public hearings at which testimony was taken, and to which manufacturers came from all over the country to make known what duties they thought they ought to have. The bill which was finally presented to the House proposed a level of duties which was so high that it has generally been considered the extreme of protection. McKinley himself justified the high rates only on the ground that without them the bill could not be passed. With the help of the Reed rules and the western Republicans the McKinley tariff reached the President and was signed by him on October 1, 1890. It went into effect at once. The more prominent features of the measure sprang from the tariff creed which had been advocated through the campaign. In order to conciliate the farmers, the protective principle was applied to agricultural products, and tariffs were laid on such articles as cereals, potatoes and flax. On the cheaper grades of wool and woolens and on carpet wools there was a slight rise over even the rates of 1883. On the higher grades of woolen, linen and clothing the increase was marked. The duty on raw sugar was removed and one-half cent per pound retained on the refined product, but domestic sugar producers were given a bounty of two cents a pound in order to protect them against the free importation of the raw material. As the sugar duty had been productive of large amounts of revenue, its remission reduced the surplus by about sixty to seventy millions of dollars. In order to encourage the manufacture of tin-plates, a considerable duty was imposed, which was to cease after 1897 unless domestic production reached specified amounts. As the result of Blaine's urgency, a reciprocity feature was introduced. The usual plan had been to reduce duties on certain products in case concessions to American goods were given by the exporting countries, but in the McKinley act the Senate inserted a novel provision. Instead of being given power to lower duties in case reciprocal reductions were made, the President was authorized to impose duties on certain articles on the free list when the exporting nation levied "unjust or unreasonable" customs charges on American products. It was expected that this plan would be applied to Latin-American countries and would increase our exports to them in return for sugar, molasses, tea, coffee and hides. In general, the McKinley act was the climax of protection. Under the impetus of President Cleveland's reduction challenge, the Republican party had recoiled to the extreme.
