On the 21st of January the senators from Florida, Alabama, and Mississippi formally withdrew from the Senate. Their speeches showed little variety of thought, consisting chiefly of indictments against the free States for placing the government under the control of an anti-slavery administration. Mr. Yulee was the first to speak. He solemnly announced to the Senate that "the State of Florida, though a convention of her people, had decided to recall the powers which she had delegated to the Federal Government, and to assume the full exercise of all her sovereign rights as an independent and separate community." At what particular period in the history of the American continent Florida had enjoyed "sovereign rights," by what process she had ever "delegated powers to the Federal Government," or at what time she had ever been "an independent and separate community," Mr. Yulee evidently preferred not to inform the Senate. His colleague, Mr. Mallory, implored the people of the North not to repeat the fatal folly of the Bourbons by imagining that "the South would submit to the degradation of a constrained existence under a violated Constitution." Mr. Mallory regarded the subjugation of the South by war as impossible. He warned the North that they were dealing with "a nation, and not with a faction." Mr. Clement C. Clay, Jr., of Alabama, boasted that in the convention which adopted the Ordinance of Secession in his State there was not one friend of the Union; and he resented with indignation what he termed the offensive calumny of the Republicans in denouncing slavery and polygamy as twin relics of barbarism. The action of Alabama, he said, was not from "sudden, spasmodic, and violent passion." It was the conclusion her people had reached "after years of enmity, injustice, and injury at the hands of their Northern brethren." Instead of causing surprise, "it is rather matter of reproach that they have endured so much and so long, and have deferred this act of self-defense until to-day." Mr. Clay's speech was insulting and exasperating to the last degree. His colleague, Mr. Fitzpatrick, a man of better tempter, showed reserve and an indisposition to discuss the situation. He contented himself with the expression of a general concurrence in the views of Mr. Clay, adding no word of bitterness himself. He said that he "acknowledged loyalty to no other power than to the sovereign State of Alabama." But for the pressure brought upon him, Mr. Fitzpatrick would have been glad to retain his seat in the Senate and wait the course of events. He was not in his heart a Disunionist, as his colleague was. He would have accepted the nomination for the Vice-Presidency on the ticket with Douglas the preceding year, if the whole political power of the Cotton States had not opposed his wishes and forced him into the support of Breckinridge.
