In 1836 the anti-slavery movement, destined to grow to such vast proportions, began to show itself in the Senate. The first contest came on the reception of petitions for the abolition of slavery in the District of Columbia. Mr. Calhoun moved that these petitions should not be received, but his motion was rejected by a large majority. The question then came on the petitions themselves, and, by a vote of thirty-four to six, their prayer was rejected, Mr. Webster voting with the minority because he disapproved this method of disposing of the matter. Soon after, Mr. Webster presented three similar petitions, two from Massachusetts and one from Michigan, and moved their reference to a committee of inquiry. He stated that, while the government had no power whatever over slavery in the States, it had complete control over slavery in the District, which was a totally distinct affair. He urged a respectful treatment of the petitions, and defended the right of petition and the motives and characters of the petitioners. He spoke briefly, and, except when he was charged with placing himself at the head of the petitioners, coldly, and did not touch on the merits of the question, either as to the abolition of slavery in the District or as to slavery itself. The Southerners, especially the extremists and the nullifiers, were always more ready than any one else to strain the powers of the central government to the last point, and use them most tyrannically and illegally in their own interest and in that of their pet institution. The session of 1836 furnished a striking example of this characteristic quality. Mr. Calhoun at that time introduced his monstrous bill to control the United States mails in the interests of slavery, by authorizing postmasters to seize and suppress all anti-slavery documents. Against this measure Mr. Webster spoke and voted, resting his opposition on general grounds, and sustaining it by a strong and effective argument. In the following year, on his way to the North, after the inauguration of Mr. Van Buren, a great public reception was given to him in New York, and on that occasion he made the speech in Niblo's Garden, where he defined the Whig principles, arraigned so powerfully the policy of Jackson, and laid the foundation for the triumphs of the Harrison campaign. In the course of that speech he referred to Texas, and strongly expressed his belief that it should remain independent and should not be annexed. This led him to touch upon slavery. He said:--
