"Mr. Clarkson divides the slaves into seven classes. The most considerable class consists of kidnapped, or stolen Africans. In obtaining these, every species of injustice, treachery and cruelty are resorted to. This class, Mr. C. supposes, embraces one half of the whole number transported from Africa. The second class consists of those whose villages are set on fire and depopulated in the darkness of night, for the purpose of obtaining a portion of their inhabitants. The third class consists of those who have been convicted of crimes. The fourth, of prisoners in wars that originate from common causes, or in wars made solely for the purpose of procuring captives for slaves. The fifth, such as are slaves by birth. The sixth and seventh, such as have surrendered their liberty by reason of debt, or by other imprudences, which last, however, are comparatively few in number. "They are sometimes brought a distance _of a thousand miles; marched over land in droves, or caufles as they are called, secured from running away, by pieces of wood which yoke them together by the neck, two and two, or by other pieces fastened with staples to their arms_. "Some are carried to what are called slave-factories; others immediately to the shore, and conveyed in boats to the different ships whose captains have captured or purchased them. The men are confined on board the ship, two and two together, either by the neck, leg, or arm, with fetters of iron; and are put into apartments, the men occupying the forepart, the women the afterpart, and the children the middle. The tops of these apartments are grated for the admission of light and for ventilation when the weather is suitable for the grates to be uncovered, and are about three feet three inches in height, just sufficient space being allotted to each individual to sit in one posture, the whole stowed away like so much lumber. "It is said that many of them whilst the ships are waiting for their full lading, and whilst they are near their native shore which they are no more to set foot upon for ever, have been so depressed, and overwhelmed with such unsupportable distress, that they have been induced to die by their own hands. _Others have become deranged and perfect maniacs, or have pined away and died with despairing, broken hearts._
