Another argument yet remains, which, though nature will absolutely turn pale at the recital, cannot possibly be omitted. In those wars, which are made for the sake of procuring slaves, it is evident that the contest must be generally obstinate, and that great numbers must be slain on both sides, before the event can be determined. This we may reasonably apprehend to be the case: and we have shewn[113], that there have not been wanting instances, where the conquerors have been so incensed at the resistance they have found, that their spirit of vengeance has entirely got the better of their avarice, and they have murdered, in cool blood, every individual, without discrimination, either of age or sex. From these and other circumstances, we thought we had sufficient reason to conclude, that, where _ten_ were supposed to be taken, an _hundred_, including the victors and vanquished, might be supposed to perish. Now, as the annual exportation from _Africa_ consists of an hundred thousand men, and as the two orders, of those who are privately kidnapped by individuals, and of those, who are publickly seized by virtue of the authority of their prince, compose together, at least, nine-tenths of the _African_ slaves, it follows, that about ten thousand consist of convicts and prisoners of war. The last order is the most numerous. Let us suppose then that only six thousand of this order are annually sent into servitude, and it will immediately appear that no less than _sixty-thousand_ people annually perish in those wars, which are made only for the purpose of procuring slaves. But that this number, which we believe to be by no means exaggerated, may be free from all objection, we will include those in the estimate, who die as they are travelling to the ships. Many of these unfortunate people have a journey of one thousand miles to perform on foot, and are driven like sheep through inhospitable woods and deserts, where they frequently die in great numbers, from fatigue and want. Now if to those, who thus perish on the _African_ continent, by war and travelling, we subjoin those[114], who afterwards perish on the voyage, and in the seasoning together, it will appear that, in every yearly attempt to supply the colonies, an _hundred thousand_ must perish, even before _one_ useful individual can be obtained.
