Chad Basin; of East Soudan and Upper Nile; and of South Africa, where the Bantu family resides. These four regions contain from four to eight great groups of black or dark-colored people representing often very widely different races speaking dissimilar languages, entirely different in their appearances and customs, and finally, having altogether separate histories.

Their descendants are either true negroes or else hybrids resulting from the former's crossing with the whites, with Indians, or other nationalities. Many of these negroes and half-castes are to be found in North and South America and the West Indies, having been forcibly introduced there through the slave-hunters of by-gone years. It is reckoned that there are some ten millions of negroes and half-breed descendants in the United States alone, and these in some sections are increasing with great rapidity, especially in the Southern States where the climate, food, and other conditions are suitable to their propagation.
