When Congress came together again in December, there was such a change in the temper of its members that no one would have imagined, on seeing the House divided, that it was the same body which had assembled there a year before. The election was over; the Whigs were to control the Executive Department of the Government for four years to come; the members themselves were either reflected or defeated; and there was nothing to prevent the gratification of such private feelings as they might have been suppressing during the canvass in the interest of their party. It was not long before some of the Northern Democrats began to avail themselves of this new liberty. They had returned burdened with a sense of wrong. They had seen their party put in deadly peril by reason of its fidelity to the South, and they had seen how little their Southern brethren cared for their labors and sacrifices, in the enormous gains which Taylor had made in the South, carrying eight out of fifteen slave States. They were in the humor to avenge themselves by a display of independence on their own account, at the first opportunity. The occasion was not long in presenting itself. A few days after Congress opened, Mr. Root, of Ohio, introduced a resolution instructing the Committee on Territories to bring in a bill "with as little delay as practicable" to provide territorial governments for California and New Mexico, which should "exclude slavery there-from." This resolution would have thrown the same House into a panic twelve months before, but now it passed by a vote of 108 to 80--in the former number were all the "Whigs from the North and all the Democrats but eight," and in the latter the entire South and the eight referred to.
