It was in 1836 that Michigan and Arkansas applied for admission as States into the Union,--one free and the other with slavery. Discussions on some technicalities concerning the conditions of Michigan's admission gave Mr. Calhoun a chance for more argumentation about the sovereignty of a State, which, considering the fact that Michigan had not then been admitted but was awaiting the permission of Congress _to be_ a State, showed the weakness of his logic in the falsity of his premise. Besides Arkansas, the slave-power also gained access to a strip of free territory north of the compromise line of 36°30' and the Missouri River. In 1837 John Quincy Adams, "the old man eloquent" of the House of Representatives, narrowly escaped censure for introducing a petition from slaves in the District of Columbia. In 1838 Calhoun introduced resolutions declaring that petitions relative to slavery in the District were "a direct and dangerous attack on the institutions of all the slave-holding States." In 1839 Henry Clay offered a petition for the repression of all agitation respecting slavery in the District. Calhoun saw and constantly denounced the danger. He knew the power of public opinion, and saw the rising tide. Conservatism heeded the warning, and the opposition to agitation intensified all over the South and the North; but to no avail. New societies were formed; new papers were established; religious bodies began to take position for and against the agitation; the Maine legislature passed in the lower House, and almost in the upper, resolutions denouncing slavery in the District; while the Abolitionists labored incessantly and vigorously to "Blow the trumpet; cry aloud and spare not; show my people their sins," as to slavery. In 1840 Van Buren and Harrison, the Democratic and Whig candidates for the presidency were both in the hands of the slave-power; and Tyler, who as Vice-President succeeded to the Executive chair on Harrison's death, was a Virginian slaveholder. The ruling classes and politicians all over the land were violently opposed to the antislavery cause, and every test of strength gave new securities and pledges to the Southern elements and their Northern sympathizers.
