Men forget what they ought not to forget; and however startling, disgusting, and oppressive to the mind of man the horrors are which characterized that trade, it is well that since they did exist the memory of them should not perish. It is a fearfully dark chapter in the history of the world, but although terrific it has its value. It is more worthy of being remembered than the historical routine of wars, defeats, or victories; for it is more illustrative of man’s proper history, and of a strange era in that history. The evidence taken by the Committee of the English House of Lords in 1850, has again thrust the subject into daylight. The slave-trade is now carried on by comparatively small and ill-found vessels, watched by the cruisers incessantly. They are therefore induced, at any risk of loss by death, to crowd and pack their cargoes, so that a successful voyage may compensate for many captures. In olden times, there were vessels fitted expressly for the purpose--large Indiamen or whalers. It has been objected to the employment of squadrons to exterminate that trade, that their interference has increased its enormity. This, however, is doing honor to the old Guineamen, such as they by no means deserve. It is, in fact, an inference in favor of human nature, implying that a man who has impunity and leisure to do evil, cannot, in the nature of things, be so dreadfully heartless in doing it, as those in whose track the avenger follows to seize and punish. The fact, however, does not justify this surmise in favor of impunity and leisure. If ever there was any thing on earth which, for revolting, filthy, heartless atrocity, might make the devil wonder and hell recognize its own likeness, then it was on any one of the decks of an old slaver. The sordid cupidity of the older, as it is meaner, was also more callous than the hurried ruffianism of the present age. In fact, a slaver now has but one deck; in the last century they had two or three. Any one of the decks of the larger vessels was rather worse, if this could be, than the single deck of the brigs and schooners now employed in the trade. Then, the number of decks rendered the suffocating and pestilential hold a scene of unparalleled wretchedness. Here are some instances of this, collected from evidence taken by the British House of Commons in 1792.
