A Clay, as much as a Calhoun, proclaimed that when abolition overthrew slavery in the South, it also would equally overthrow the Constitution. Calhoun, and other Southern statesmen, with a sagacity which every day confirms, had forewarned us, that when once abolition by federal aggression came, these other sure results would follow: that the same greedy lust of power which had meddled between masters and slaves, would assuredly, and for the stronger reason, desire to use the political weight of the late slaves against their late masters: that having enforced a violent emancipation, they would enforce, of course, negro suffrage, negro eligibility to office, and a full negro equality: that negro equality thus theoretically established would be practical negro superiority: that the tyrant section, as it gave to its victims, the white men of the South, more and more causes of just resentment, would find more and more violent inducements to bribe the negroes, with additional privileges and gifts, to assist them in their domination: that this miserable career must result in one of two things, either a war of races, in which the whites or the blacks would be, one or the other, exterminated; or amalgamation. But while we believe that "God made of one blood all nations of men to dwell under the whole heavens," we know that the African has become, according to a well-known law of natural history, by the manifold influences of the ages, a different, fixed _species_ of the race, separated from the white man by traits bodily, mental and moral, almost as rigid and permanent as those of _genus_. Hence the offspring of an amalgamation must be a hybrid race, stamped with all the feebleness of the hybrid, and incapable of the career of civilization and glory as an independent race. And this apparently is the destiny which our conquerors have in view. If indeed they can mix the blood of the heroes of Manassas with this vile stream from the fens of Africa, then they will never again have occasion to tremble before the righteous resistance of Virginian freemen; but will have a race supple and vile enough to fill that position of political subjection, which they desire to fix on the South.
