The “free negro” in our midst perishes; but in the tropics, in his own climate, he poisons and destroys the white blood, and then relapses into his inherent and organic Africanism, toward which he is rapidly impelled by the British “anti-slavery policy.” If that policy could ever be successful—if fifty degrees of latitude in the heart of this continent should ever be permanently turned over to free negroism, or ever occupied by a huge barbarism—which should not alone render the fairest portion of the New World a barren waste, but interrupt that great law of progress which impels us onward, to carry our system, our republican idea of government, and our civilization, over the whole “boundless continent,” then, indeed, might the friends of freedom despair of the future. But it is not possible that the rising civilization of America is to be thus broken down by the monarchists of the Old World. The law of progress—of national growth, of very necessity—that has carried us to the Gulf of Mexico and to the Pacific Ocean, will continue to impel us onward, and to restore the rapidly perishing civilization of the great tropical center of the continent. All humane and good men desire that this grand result shall be worked out by moral causes, by the exposure of the monstrous delusion in regard to negroes that has been productive of so much evil; but either through an appeal to reason or to the sword—through the operation of natural causes or through bloodshed and national suffering—the final end _must be_ the restoration of the negro to his normal condition, and consequent restoration of civilization in the finest portion of our great continent. CHAPTER XXIV. CONCLUSION. It has been shown in the foregoing pages of this work how that providential arrangement of human affairs, in which the negro is placed in natural juxtaposition with the white man, has resulted in the freedom of the latter and the general well-being of both. It has been seen how a subordinate and widely different social element in Virginia and other States, naturally gave origin to new ideas and new modes of thought, which, thrusting aside the mental habits and political notions brought from the Old World, naturally culminated in the grand idea of 1776, and the establishment of a new political existence, based on the natural, organic, and everlasting equality of the race. It has been seen, moreover, how the great civil revolution of 1800, which, under the lead of Mr. Jefferson, restored the purity and simplicity of republican principles, saved the Northern laboring and producing classes from the rule of an oligarchy, otherwise unavoidable, however it might have been disguised by republican formulas.
