been known to the white race. Thus the Hottentots and the Abyssinians have maintained themselves in their respective homes without change ever since their existence has been known to us, even though their number is less than that of our pure black population. The same, also, is the case with the population of Australia and of the Pacific islands. The Papuan race, the Negrillo race, the Australian race proper, distinct from one another, as well as from all other inhabitants of the earth, number each fewer inhabitants than already exist of the negro race in the United States alone, not to speak of Central and South America. This being the case there is, it seems to me, no more reason to expect a disappearance of the negro race from the continent of America without violent interference, than to expect a disappearance of the races inhabiting respectively the South Sea Islands, Australia, the Cape of Good Hope, or any other part of the globe tenanted by the less populous races. The case of the American Indians, who gradually disappear before the white race, should not mislead us, as it is readily accounted for by the peculiar character of that race. The negro exhibits by nature a pliability, a readiness to accommodate himself to circumstances, a proneness to imitate those among whom he lives,--characteristics which are entirely foreign to the Indian, while they facilitate in every way the increase of the negro. I infer, therefore, from all these circumstances that the negro race must be considered as permanently settled upon this continent, no less firmly than the white race, and that it is our duty to look upon them as co-tenants in the possession of this part of the world.
