Northwest cession 286,681 square miles. Louisiana cession 1,189,112 do. Florida and Oregon cession 400,731 do. Mexican cession 526,078 do. --------- Total 2,377,602 do. Of all this territory the Southern States have been permitted to enjoy only 283,713 square miles, while the Northern States have been allowed 2,083,889 square miles, or between seven and eight times more than has been allowed to the South. The following are some of the invasions that have been from time to time proposed upon the Constitution in the halls of Congress by these agitators: 1. That the clause allowing the representation of three-fifths of the slaves shall be obliterated from the Constitution; or, in other words, that the South, already in a vast and increasing minority, shall be still further reduced in the scale of insignificance, and thus, on every attempted usurpation of her rights, be far below the protection of even a Presidential veto. Next has been demanded the abolition of slavery in the District of Columbia, in the forts, arsenals, navy yards and other public establishments of the United States. What object have the abolitionists had for raising all this clamor about a little patch of soil ten miles square, and a few inconsiderable places thinly scattered over the land--a mere grain of sand upon the beach--unless it be to establish the precedent of Congressional interference, which would enable them to make a wholesale incursion upon the constitutional rights of the South, and to drain from the vast ocean of alleged national guilt its last drop? Does any one suppose that a mere microscopic concession like this would alone appease a conscience wounded and lacerated by the "sin of slavery?" Another of these aggressions is that which was proposed under the pretext of regulating commerce between the States--namely, that no slave, for any purpose and under any circumstances whatever, shall be carried by his lawful owner from one slaveholding State to another; or, in other words, that where slavery now is there it shall remain forever, until by its own increase the slave population shall outnumber the white race, and thus by a united combination of causes--the fears of the master, the diminution in value of his property and the exhausted condition of the soil--the final purposes of fanaticism may be accomplished.
