It was seen that the economic rehabilitation of Cuba must come about mainly through the production of sugar, and since the United States was the chief purchaser of the product, the tariff schedule was of vital importance. In 1901 Congress was urged to reduce the tariff on imports from Cuba, but the opposition was formidable. The American Beet Sugar Association complained that their industry, which had been recently established, would be ruined by allowing reductions to Cuban growers; the cane-sugar planters of Louisiana were allied with them; and the friends of protection feared the effect of any break in the tariff wall. On the other hand, the American Sugar Refining Company, popularly called the "Sugar Trust," merely refined raw sugar and desired an increase in the supply. Lobbyists of all descriptions poured into Washington to influence committees and individuals, and General Leonard Wood, then the Governor of Cuba, even expended Cuban funds in the spread of literature favorable to a reciprocal reduction of duties. In the meantime, a reciprocity treaty was made and submitted to the Senate, where it hung fire for somewhat more than a year, and was finally ratified on December 16, 1903. It provided for the admission of Cuban products into the United States at a reduction of twenty per cent., and a reciprocal reduction on American goods entering Cuba of twenty-five to forty per cent. The establishment of a policy in regard to permanent relations between the United States and Cuba was brought about in 1901-1902. When Congress had demanded the withdrawal of Spain from the island in 1898, its action had been accompanied by the Teller Resolution, disclaiming any intention of keeping Cuba and asserting a determination to leave the control of the island with its people. After the close of the war President McKinley and his closest advisors in Congress had determined that the pledge should be kept, and public sentiment had been in agreement with them. As soon, therefore, as American control was an established fact, plans were formulated for relinquishing Cuba to the people of the island. A constitutional convention was held, and a form of government, modelled on that of the United States, was framed and adopted on February 21, 1901.
