"Professor Carver, who teaches scientific agriculture, botany, agricultural chemistry, etc., at Tuskegee, is, as regards complexion and features, an absolute Negro; but in the cut of his clothes, the accent of his speech, the soundness of his science, he might be professor of botany, not at Tuskegee, but at Oxford or Cambridge. Any European botanist of distinction, after ten minutes' conversation with this man, instinctively would treat him as a man on a level with himself."
