The slaves in Africa, I suppose, are nearly in the proportion of three to one to the freemen. They claim no reward for their services except food and clothing, and are treated with kindness or severity, according to the good or bad disposition of their masters. Custom, however, has established certain rules with regard to the treatment of slaves, which it is thought dishonourable to violate. Thus the domestic slaves, or such as are born in a man’s own house, are treated with more lenity than those which are purchased with money. The authority of the master over the domestic slave, as I have elsewhere observed, extends only to reasonable correction; for the master cannot sell his domestic, without having first brought him to a public trial before the chief men of the place. But these restrictions on the power of the master extend not to the case of prisoners taken in war, nor to that of slaves purchased with money. All these unfortunate beings are considered as strangers and foreigners, who have no right to the protection of the law, and may be treated with severity, or sold to a stranger, according to the pleasure of their owners. There are, indeed, regular markets, where slaves of this description are bought and sold, and the value of a slave, in the eye of an African purchaser, increases in proportion to his distance from his native kingdom: for when slaves are only a few days’ journey from the place of their nativity they frequently effect their escape; but when one or more kingdoms intervene, escape being more difficult, they are more readily reconciled to their situation. On this account the unhappy slave is frequently transferred from one dealer to another, until he has lost all hopes of returning to his native kingdom. The slaves which are purchased by the Europeans on the coast are chiefly of this description. A few of them are collected in the petty wars, hereafter to be described, which take place near the coast, but by far the greater number are brought down in large caravans from the inland countries, of which many are unknown, even by name, to the Europeans. The slaves which are thus brought from the interior may be divided into two distinct classes—first, such as were slaves from their birth, having been born of enslaved mothers; secondly, such as were born free, but who afterwards, by whatever means, became slaves. Those of the first description are by far the most numerous, for prisoners taken in war (at least such as are taken in open and declared war, when one kingdom avows hostilities against another) are generally of this description. The comparatively small proportion of free people to the enslaved throughout Africa has already been noticed: and it must be observed that men of free condition have many advantages over the slaves, even in war time. They are in general better armed, and well mounted, and can either fight or escape with some hopes of success; but the slaves, who have only their spears and bows,
