Children, whose ancestors have, for ages, ranked among the highly cultivated of the earth,—each generation surpassing its predecessor in knowledge, in science, and religion,—have been found to degenerate, oftener than otherwise, when trained solely by arguments addressed to their reason, and unaccompanied by physical compulsion. What then are we to expect from man in a savage state, whose ancestors have been degenerating from generation to generation, through untold ages,—him, who has scarcely a feeling in common with civilized man, except such as is common to the mere animal,—him, whom deteriorating causes have reduced to the lowest grade above the brute? Domberger spent twelve years in passing through the central parts of Africa, from north to south. He found the negroes, in a large district of country, in a state of total brutality. Their habits were those only of the wild brutes. They had no fixed residences. They lay down wherever they might be when disposed to sleep. They were not more gregarious than the wild goats. So far as he could discover, they had not a language even, by which to hold intercourse with each other. They possessed no power by which they were enabled to exhibit moral degradation, any more than the wild beasts. Hanno, the Carthaginian navigator, in his Periplus, eight hundred years before the birth of Christ, gives a similar account of a race he calls Gætuli. It is possible that man, in these extreme cases, where there is very little to unlearn, might sooner be regenerated, elevated to civilization, physical and mental power, than in other cases where there may be far more proof of mental capacity, but where the worst of intellectual and physical habits have stained soul and body with, perhaps, a more indelible degradation. It would be a curious experiment, and add much to our knowledge of the races of man, to ascertain how many generations, under the most favourable treatment, it would require to produce an equal to Moses, or a David, a Newton, or the learned Dr. Wayland himself, (if such be possible,) from these specimens of man presented before us! And we now inquire, what course of treatment will you propose, as the most practical, to elevate such a race to civilization? It appears to us God has decided that slavery is the most effectual.
