Thus panoplied they made a desperate contest for the possession of Kansas. They had found that all the crops grown in Missouri by slave labor could be as profitably cultivated in Kansas. Securing Kansas, they would gain more than the mere material advantage of an enlarged field for slave labor. New Mexico at that time included all of Arizona; Utah included all of Nevada; Kansas, as organized, absorbed a large part of what is now Colorado, stretched along the eastern and northern boundary of New Mexico, and, crossing the Rocky Mountains, reached the confines of Utah. If Kansas could be made a slave State it would control New Mexico and Utah, and the South could again be placed in a position of political equality if not of command. The repeal of the Missouri Compromise had shown them for the first time that they could absolutely consolidate the Southern vote in Congress in defense of slavery, regardless of differences on all other issues. But this power was of no avail, unless they could regain their equality in the Senate which had been lost by what they considered the mishap of California's admission. While Clay and Benton were in the Senate with their old reverence for the Union and their desire for the ultimate extinction of slavery, California could neither be kept out nor divided on the line of 36 deg. 30'. But the new South, the South of Jefferson Davis and Alexander H. Stephens, of Robert Toombs and Judah P. Benjamin, of James M. Mason and John C. Breckinridge, had made new advances, was inspired by new ambitions, and was determined upon the consolidation of sectional power. The one supreme need was another slave State. If this could be acquired they felt assured that so long as the Union should exist no free State could be admitted without the corresponding admission of another slave State. They would perhaps have been disappointed. Possibly they did not give sufficient heed to the influences which were steadily working against slavery in such States as Delaware and Maryland, threatening desertion in the rear, while the defenders of slavery were battling at the front. They argued, however, and not unnaturally, that prejudice can hold a long contest with principle, and that in the general uprising of the South the tendency of all their old allies would be to remain firm. They reckoned that States with few slaves would continue to stand for Southern institutions as stubbornly as States with many slaves. In all the States of the South emancipation had been made difficult, and free negroes were tolerated, if at all, with great reluctance and with constant protest.
