Movements of the Barnburners. The movements of the barnburners, or the cut-throats, as they are designated by the hunkers, create a great deal of interest about these days. Their leaders and their organs make a great fuss about purity, principle, liberty, and what not, as if the public ever accused them of possessing one of these traits; but we apprehend the public are as well acquainted with their virtues, as they are themselves, and perhaps a little better. All this palaver about patriotism and principle, is all nonsense. Their virtue, their principle, their integrity, and their patriotism, are all centered in ex-President Van Buren; and it is he, and he alone, that constitutes the front, rear and embodiment of their principles. They care much more for him than for any thing else; and as revenge is sweet, they are determined, if they can, to revenge the defeat of his nomination at the Baltimore convention in 1844, by defeating the election of General Cass in 1848.

Ex-President Van Buren, by the action of the Baltimore convention, and that of the barnburners, at the present time, is placed in a somewhat singular position—one resembling very much that which John C. Calhoun, of South Carolina, occupies. When Mr. Calhoun was defeated by General Jackson, he raised the standard of nullification, and organized, in his own State, the nullifying party, which now, as a party, holds the most ultra views on the subject of slavery; and ex-President Van Buren, being defeated by General Cass, has, with the same motives, identified himself with the most ultra anti-slavery principles. Mr. Calhoun takes ground against the slave, and Mr. Van Buren occupies the opposite position, and in the plenitude of his philanthropy, jumps, at a bound, to the salt lakes of California, where he has planted himself as the especial guardian of the slaves that may hereafter be planted on their banks.

The mass meeting of the barnburners will be held in this city to-morrow, in the Park. It will undoubtedly, in the present position of the political world, be extremely interesting, exciting, and revolutionary. We shall report it faithfully and accurately, take the part of an umpire between the two sections, and see that no foul play is resorted to by either.
