There are exceptional cases among the negroes as among the whites; but because we have a Cuvier, a Webster, a Dupuytren, are we prepared to assert as a general fact that the brain of the white man weighs sixty-four ounces? And I speak of the negroes as a class. I refer to the negro of the South, not to the barbarian of Africa, who really exists, nor to the negro of the Northern mind, who is only "founded on fact." I refer to the negro as he is in our day and generation, not as he will or may be after centuries of revolution in his circumstances which will produce Heaven knows what changes in his mental, moral and physical nature. Many believe that these negroes, whom and whose children we have civilized, having with their freedom received ideas of social equality and personal ambition which except in isolated cases can never be realized on this continent, will gradually return, as in South Carolina they are now doing, to their original land, and thus eventually civilize their own race. Were they to return in a body, they would all probably relapse into barbarism, but if a clear stream be kept running, though the pool through which it flow be stagnant, it will in time become pure. And there is material in this country for a pretty continuous flow. I do not say that the negro is incapable of progress, but his mental horizon is very limited, and seems bounded by natural causes as immovable (except by aid of foreign blood, which having he ceases to be a genuine negro) as the chains of mountains which in some localities limit the horizon in material Nature; and that as a people they will become the peer of the white race is simply impossible, for if progress be a law of Nature, it will be obeyed by the white man also, and he is already centuries ahead of the black, with advantages of every possible nature. Also, that they should now be competent to fill the offices many of them occupy is a pure absurdity, as demonstrated all around us--at the polls, in the jury-box, in the chair of the magistrate. A very cruel absurdity it has sometimes proved.
