Early in the year Andrew Jackson was called to Washington. He was the hero of the day. When he visited New York he was received with public honors. On February 22, a treaty with Spain was adopted by which she surrendered all claims to Florida and ceded West Florida. The cost of the war to the United States had been forty million dollars. The year was marked by the enforced retirement of large bodies of the Cherokees from Georgia to the Mississippi. The Cherokees as well as the Creeks, the Choctaws and the Chickasaws were greatly perturbed at the prospect of their final removal from the land which the United States had guaranteed to them. Partly as a result of these changes, the Territory of Alabama was admitted to the Union as the twenty-second State. [Sidenote: The Missouri problem] There were now eleven free and eleven slave States; and serious opposition arose to the admission of Missouri. In February, the first bill was introduced in the House for the admission of that Territory. James Tallmadge, Jr., of New York, proposed that there should be no personal servitude in the State except by those already held as slaves, and that these should be manumitted within a certain period. This proposition he modified by moving an amendment providing that the introduction of slavery should be prohibited, but that those already slaves in Missouri should remain so, and that the children of such slaves should be liberated upon reaching the age of twenty-five. The proposition to hold in slavery a generation yet unborn was fiercely resented. The two Houses did not agree, and the question went over to another year. The South presented an unbroken and unyielding front. Caleb of Georgia said that this attempt to interfere with slavery was "destructive of the peace and harmony of the union"; that those who proposed it "were kindling a fire which all the waters of the ocean could not extinguish. It could be extinguished only in blood." [Sidenote: Antagonism to slavery] [Sidenote: Maine _vs._ Missouri]
