The history of the development of the race concept in the world and particularly in America was naturally reflected in the education. In the elementary school it came only in the matter of geography when the races of the world were pictured: Indians, Negroes and Chinese, by their most uncivilized and bizarre representatives; the whites by some kindly and distinguished-looking philanthropist. The eternal walls between races did not seem so stern and exclusive. It is probably quite natural for persons of low degree, who have reached any status, to search feverishly for distinguished ancestry, as a sort of proof of their inherent desert. America indeed has meant the breaking down of class bars which imprisoned personalities and capabilities and allowing new men and new families to emerge. In the United States the income of the Cotton Kingdom based on black slavery caused the passionate belief in Negro inferiority and the determination to enforce it even by arms.
