“I believe that the Anglo-Americans, with the Africans, whom a part of the former now hold in bondage, will one day unite to form this race for the tropics, with or without combination with the races already there. But whether the African quota of it shall be transferred thither by convulsive or organized movements--or be gradually thinned out from their present abode, as from a great nursery, by directed but spontaneous transition--or retire, by degrees, with the ‘poor whites,’ before the peaceful encroachments of robust Northern labor, it would be useless now to conjecture. It is enough now to know that labor, like capital, goes in the end to the place where it is most wanted; and that labor, free from the destructive element of caste, has been, and still is, the great desideratum of the tropics, as it is of all other places which do not already possess it. I have already spoken of the presumed ability of the Southern States to spare this kind of labor. Should there, however, prove to be any part of the Union where the climate or the culture really requires the labor of the black man, then there he will remain, and eventually be absorbed by the dominant race; and from that point the complexion of our population will begin to shade off into that of the dark belt of Anglo-Africans, which will then extend across the northern tropics. “I know that most of our Northern people, while they demand, in the strongest terms, all the rights of man for the negro or mulatto, are unable to eradicate from their minds a deeply-grounded prejudice against his person. In spite of themselves, they shrink from the thought of an amalgamation such as the foregoing observations imply. But these friends are not aware how quickly this prejudice begins to melt away as soon as one has entered any part of the tropics where the African race is in the ascendant, or where people of colored blood have attained to such social consideration as to make themselves respected. I suppose no Northern man ever forgets the occasion when, for the first time, he arrives at such a place, and the colored merchant to whom he is addressed comes forward, with the self-possession which attends self-respect, and offers him his hand. He begins to be healed of his prejudice from that hour.”
