When a negro has, by means like these, once fallen into the hands of his enemies, he is either retained as the slave of his conqueror, or bartered into a distant kingdom; for an African, when he has once subdued his enemy, will seldom give him an opportunity of lifting up his hand against him at a future period. A conqueror commonly disposes of his captives according to the rank which they held in their native kingdom. Such of the domestic slaves as appear to be of a mild disposition, and particularly the young women, are retained as his own slaves. Others that display marks of discontent are disposed of in a distant country; and such of the freemen or slaves as have taken an active part in the war are either sold to the slatees or put to death. War, therefore, is certainly the most general and most productive source of slavery, and the desolations of war often (but not always) produce the second cause of slavery, _famine_; in which case a freeman becomes a slave to avoid a greater calamity. Perhaps, by a philosophic and reflecting mind, death itself would scarcely be considered as a greater calamity than slavery; but the poor negro, when fainting with hunger, thinks like Esau of old, “Behold, I am at the point to die, and what profit shall this birthright do to me?” There are many instances of freemen voluntarily surrendering up their liberty to save their lives. During a great scarcity, which lasted for three years, in the countries of the Gambia, great numbers of people became slaves in this manner. Dr. Laidley assured me that at that time many freemen came and begged, with great earnestness, _to be put upon his slave-chain_, to save them from perishing of hunger. Large families are very often exposed to absolute want; and as the parents have almost unlimited authority over their children, it frequently happens, in all parts of Africa, that some of the latter are sold to purchase provisions for the rest of the family. When I was at Jarra, Daman Jumma pointed out to me three young slaves whom he had purchased in this manner. I have already related another instance which I saw at Wonda; and I was informed that in Fooladoo, at that time, it was a very common practice.
