Surely the good people of the north ought to learn the difference between the negro race and the white. There is a small class of exceptional negroes which is assumed by a great many at the north to be most fair samples of the average negro of the south. Dr. Washington and Professor DuBois severally lead the opposing sections of this class. It consists of authors, editors, preachers, speakers, some who with small capital in banking, farming, and other business, have each by Booker Washington's blazon been exalted into a national celebrity, and others. Its never-sleeping resolve, fondly cherished by the greater part, is to "break into" white society and some day fuse with it. Its members are nearly all at least half white, and many are more than half white. But when a Bourbon snub to one of them is received, as it often is, with dignity and proper behavior, Mr. Louis F. Post, and a few more, exclaim to the country, "See how this coal-black and pure negro excels his would-be superiors!" This man, almost white, is to them a coal-black, genuine, unmixed negro. Ought not attention to facts incontrovertibly cardinal to rule here as everywhere else? To what is due the great accomplishment of Dumas, Douglass, and Booker Washington--to their negro blood or to their white blood? If half negro blood can do so well, why is it that pure negro blood does not do far better? I have seen it asserted that Professor Kelly Miller is pure negro. His head has the shape of a white man's. The greyhound crossed once with the bull-dog, as Youatt tells, and each succeeding generation of offspring recrossed with pure greyhound until not a suggestion of bull-dog was visible, occurs to me. Thus there was bred a greyhound, possessing the desired trait of the bull-dog. Who can say that there is not among the professor's American ancestors one of half white blood? If there is in fact no such, he is, in his high attainment, almost a _lusus naturae_. The north, by due attention, will discern that the small number constituting what I provisionally name the upper class of negroes, is hardly involved in the race question.
