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.

Notwithstanding the frequent triumphs of the South, aided by Whigs and Democrats from the North, who played into the hands of Southern politicians, Mr. Calhoun was not entirely at rest in his mind. He saw with alarm the increasing immigration into the Western States, which threatened to disturb the balance of power which the South had ever held; and with the aid of Southern leaders he now devised a new and bold scheme, which was to annex Texas to the United States and thus enlarge enormously the area of slavery. It was probably his design, not so much to strengthen the slaveholding interests of South Carolina, as to increase the political power of the South. By the addition of new slave States he could hope for more favorable legislation in Congress. The arch-conspirator--the haughty and defiant dictator--would not only exclude Congress from all legislation over its own territory in the national District, but he now would make Congress bolster up his cause. He could calculate on a "solid South," and also upon the aid of the leaders of the political parties at the North,--"Northern men with Southern principles,"--who were strangely indifferent to the extension of slavery.

The Abolitionists were indeed now a power, but the antislavery sentiment had not reached its culmination, although it had become politically organized. For the campaign of 1840, seeing the futility of petition and the folly of expecting action on issues foreign to those on which Congressmen had been elected, the Abolitionists boldly called a National Convention, in which six States were represented, and nominated candidates for the presidency and vice-presidency. It was a small and despised beginning, but it was the germ of a mighty growth. From that time the Liberty Party began to hold State and National Conventions, and to vote directly on the question of representatives. They did not for years elect anybody, but they defeated many an ultra pro-slavery man, and their influence began to be felt. In 1841 Joshua R. Giddings, from Ohio, and in 1843 John P. Hale from New Hampshire and Hannibal Hamlin from Maine brought in fresh Northern air and confronted the slave-power in Congress, in alliance with grand old John Quincy Adams,--whose last years were his best years, and have illumined his name.

Most of the antislavery men were still denounced as fanatics, meddling with what was none of their business. In 1843 they had not enrolled in their ranks the most influential men in the community. Ministers, professors, lawyers, and merchants generally still held aloof from the controversy, and were either hostile or indifferent to it. So, with the aid of the "Dough-Faces," as they were stigmatized by the progressive party, Calhoun was confident of success in the Texan scheme.

At that time many adventurers had settled in Texas, which was then a province of Mexico, and had carried with them their slaves. In 1820 Moses Austin, a Connecticut man, long resident in Missouri, obtained large grants of land in Texas from the Mexican government, and his son Stephen carried out after the father's death a scheme of colonization of some three hundred families from Missouri and Louisiana. They were a rough and lawless population, but self-reliant and enterprising. They increased rapidly, until, in 1833, being twenty thousand in number, they tried to form a State government under Mexico; and, this being denied them, declared their independence and made revolution. They were headed by Sam Houston, who had fought under General Jackson, and had been Governor of Tennessee. In 1836 the independence of Texas was proclaimed. Soon after followed the battle of San Jacinto, in which Santa Anna, the President of the Mexican republic and the commander of the Mexican forces, was taken prisoner.

Immediately after this battle Mr. Calhoun tried to have it announced as the policy of the government to recognize the independence of Texas. When Tyler became President, by the death of Harrison, although elected by Whig votes he entered heart and soul into the schemes of Calhoun, who, to forward them, left the Senate, and became Secretary of State, as successor to Mr. Upshur. In 1843 it became apparent that Texas would be annexed to the United States. In that same year Iowa and Florida--one free, the other slave--were admitted to the Union.

The Liberty party beheld the proposed annexation of Texas with alarm, and sturdily opposed it as far as they could through their friends in Congress, predicting that it would be tantamount to a war with Mexico. The Mexican minister declared the same result. But "Texas or Disunion!" became the rallying cry of the South. The election of Polk, the annexationist Democrat, in 1844, was seized upon as a "popular mandate" for annexation, although had not the Liberty Party, who like the Whigs were anti-annexationists, divided the vote in New York State, Clay would have been elected. The matter was hurried through Congress; the Northern Democrats made no serious opposition, since they saw in this annexation a vast accession of territory around the Gulf of Mexico, of indefinite extent. Thus, Texas, on March 1, 1845, was offered annexation by a Joint Resolution of the Senate and House of Representatives, in the face of protests from the wisest men of the country, and in spite of certain hostilities with Mexico. On the following fourth of July Texas, accepting annexation, was admitted to the Union as a slave State, to the dismay of Channing, of Garrison, of Phillips, of Sumner, of Adams, and of the whole antislavery party, now aroused to the necessity of more united effort, in view of this great victory to the South; for it was provided that at any time, by the consent of its own citizens, Texas might be divided into four States, whenever its population should be large enough; its territory was four times as large as France.

The Democratic President Polk took office in March, 1845; the Mexican War, beginning in May, 1846, was fought to a successful close in a year and five months, ending September, 1847; the fertile territory of Oregon, purchased from Spain, had been peaceably occupied by rapid immigration and by settlement of disputed boundaries with Great Britain; California--a Mexican province--had been secured to the American settlers of its lovely hills and valleys by the prompt daring of Capt. John C. Frémont; and the result of the war was the formal cession to the United States by Mexico of the territories of California and New Mexico, and recognition of the annexation and statehood of Texas.

Both the North and the South had thus gained large possibilities, and at the North the spirit of enterprise and the clear perception of the economic value of free labor as against slave labor were working mightily to help men see the moral arguments of the antislavery people. The division of interest was becoming plain; the forces of good sense and the principles of liberty were consolidating the North against farther extension of the slave-power. The perils foreseen by Calhoun, which he had striven to avoid by repression of all political discussion of slavery, were nigh at hand. The politicians of the North, too, scented the change, and began to range themselves with their section; and, while there was a long struggle yet ahead before the issues would be made up, to the eye of faith the end was already in sight, and the "Free-Soilers" now redoubled their efforts both in discussion and in political action.
