Any one who has ever had the misfortune to witness an African slave-market, and for a moment to stand surrounded by its wretched, emaciated victims, must, after his first feelings have subsided, have found himself filled with astonishment that human nature could ever be induced deliberately to continue so guilty a traffic! To account for it, or, rather, to excuse it, it has often been urged that negroes are a race of inferior beings, whose minds are not susceptible of those painful sensations which we should suffer were we to be placed in their unfortunate condition. In short, to explain the problem, we paint the map of the world in our own way, and then gravely say, "the inhabitants of these (our countries) have acute feelings, and those who dwell in that have none!"[24] But this strange assertion is most curiously contradicted by the history of the negroes or Shangalla of Abyssinia; for they and their enemies, the persecuted and the persecutors, absolutely live under the same sun, in the same country, and separated only by a few hundred feet of elevation. No one can therefore rationally maintain that these children of one family can be divided by feelings of such different degrees of susceptibility; for the Shangalla must surely enjoy freedom and independence in the valley, as much as the Abyssinians can enjoy them on the higher ground. But the real truth is, that the sun is hotter in the lower stratum than it is in the upper. The human body, exhausted by its heat, becomes weaker; and it is because the Shangalla are less powerful than the Abyssinians, and for no other reason, that the former are murdered and persecuted by the latter. The African slave-trade rests precisely on the same foundation. THE GALLA. The Galla are a very numerous race of shepherds living to the south and west of Abyssinia, and also in parts of the interior of that country. As their land is high, and the rains screen it for a considerable time from the sun, the general complexion of these people is brown; though some who inhabit the valley of the lower country are perfectly black, with long hair of the same colour. They are divided into tribes, for every seven of which a king or chief is elected. There exists, also, a sort of rude nobility among them, whose ancestors have been raised to this dignity by valorous feats in war; and it is from these families alone that the chieftain can be chosen.
