But slave-exportation is practically dead; we would not revive it, nor indeed could we, the revival would be a new institution, completely in disaccord with the spirit of the age. It is for us to find something which shall take its place, and which shall satisfy the just aspirations of those who see their industry and energy neutralized by want of labour. I need hardly say that all requirements would be met by negro-emigration; and that not only Africa, but the world of the east as well as of the west, call for some measure of the kind. The "cooly" from Hindostan may in time become a valuable article, but it will be long before he can be induced to emigrate in sufficient numbers: the Chinese will be a mistake when the neglected resources of the mighty "Central Empire," mineral and others, shall be ready to be developed, as they soon must, under the supervision of Europeans. It remains only for us to draw upon the great labour-bank of Negro-land. A bonâ fide emigration, a free engagé system, would be a boon to Western and Inner Africa, where the tribes live in an almost continual state of petty warfare. The anti-slavers and the abolitionists, of course, represent this to be the effect of the European trade in man's flesh and blood; but it prevails, and has ever prevailed, and long will prevail, even amongst peoples which have never sent a head of negro to the coast. And there is a large class of men captured in battle, and a host of those condemned to death by savage superstition, whose lives can be saved only by their exportation, which, indeed, is the African form of transportation. "We believe," says the Abbé Proyart (1776), "that the father sells his son and the prince his subjects; he only who has lived among them can know that it is not even lawful for a man to sell his slave, if he be born in the country, unless he have incurred that penalty by certain crimes specified by law."
