His physical organism is adapted to the cultivation of these products as perfectly as is his grade of intelligence. His head is protected from the rays of a vertical sun by a dense mat of woolly hair, wholly impervious to its fiercest heats, while his entire surface, studded with innumerable sebaceous glands, forming a complete excretory system, relieves him from all those climatic influences so fatal, under the same circumstances, to the sensitive and highly organized white man. Instead of seeking to shelter himself from the burning sun of the tropics, he courts it, enjoys it, delights in its fiercest heats, and malaria—that deadly poison to the white man, which, in the form of yellow fever, has swept from existence vast multitudes of our race, is as harmless to the negro organism as the balmy breezes of May or June to the organization of the white man. Of course mulattoes and mongrels may have something that approximates to the yellow fever of the white man, but to the negro it is simply an organic impossibility. His faculties, his simple grade of intelligence, his physical organism, his specific, climatic, and industrial adaptations are therefore in perfect harmony with the primitive soils, the simple products, and uniform atmosphere of the tropics, and in complete relation and perfect union with the circumstances that surround him in the centre of existence where the Almighty has placed him. The late Daniel Webster once declared that God had limited “slavery” to certain climates, and that he, at least, would not “reënact the will of God,” and this declaration, though as a form of speech absurd enough, was certainly in close neighborhood to a great and vital truth. If he had said that the Almighty had adapted the negro to certain climates, he would have expressed just what we are now considering; but the relation of the negro to the white man, the thing he called slavery, is, of course, as proper and as natural in New York or Ohio as in Mississippi. The vulgar notion, therefore, that “slave labor,” the industrial capacities of the negro, is unprofitable in temperate latitudes is only partially true. The “slave” relation, the normal condition, as contrasted with the so-called free negro, presents just the difference between a useful negro and a worthless negro, or a negro who adds to the productive forces of a State, and one who lives on the State—a healthy and a diseased social element, and therefore wherever found, if, indeed, in the extreme North, it is simply absurd to speak of the former as unprofitable when contrasted with the latter. But when the negro is contrasted with the white man in Ohio or New York, then the whole subject is changed. His industrial capacities are incompetent to grow the indigenous products of the temperate latitudes.
