necessary for coaling or naval stations"; that it would provide for the sanitation of its cities; and that the United States should have the right to intervene, "for the preservation of Cuban independence, the maintenance of a government adequate for the protection of life, property, and individual liberty, and for discharging" certain obligations with respect to Spanish subjects which the United States had assumed in the treaty signed at Paris. After some hesitation the convention added these provisions to the new constitution of Cuba. On May 20, 1902, the American troops withdrew, leaving Cuba in better condition than she had ever been before. Subsequently the United States was forced to intervene to preserve order, but, though the temptation was strong to remain, the American troops again withdrew after they had done their constructive work. The voluntary entrance of Cuba into the Great War in cooperation with the United States was a tribute to the generosity and honesty of the American people. * An amendment to the Army Appropriation Bill of March 2, 1901. Porto Rico presented a problem different from that which the United States had to solve in Cuba. There existed no native organization which could supply even the basis for the formation of a government. The people seemed, indeed, to have no desire for independence, and public sentiment in the United States generally favored the permanent possession of the island. After a period of rule entirely at the discretion of the President, Congress established in 1900 a form of government based on that of the American territories. Porto Rico remained, however, unincorporated into the Union, and it was long doubtful whether it would remain a dependency or would ultimately attain statehood. In 1917, however, the degree of self-government was increased, and the inhabitants were made American citizens. It now seems probable that the island will ultimately become a State of the Union.
