The heat and the smell of these rooms, when the weather will not admit of the Slaves being brought upon deck, and of having their rooms cleaned every day, would be, almost, insupportable, to a person not accustomed to them. If the Slaves and their rooms can be constantly aired, and they are not detained too long on board, perhaps there are not many who die; but the contrary is often their lot. They are kept down, by the weather, to breathe a hot and corrupted air, sometimes for a week: this, added to the galling of their irons, and the despondency which seizes their spirits, when thus confined, soon becomes fatal. And every morning, perhaps, more instances than one are found, of the living and the dead, like the Captives of Mezentius, fastened together. Epidemical fevers and fluxes, which fill the ship with noisome and noxious effluvia, often break out, infect the Seamen likewise, and the Oppressors, and the Oppressed, fall by the same stroke. I believe, nearly one half of the Slaves on board, have, sometimes, died; and that the loss of a third part, in these circumstances, is not unusual. The ship, in which I was Mate, left the Coast with Two Hundred and Eighteen Slaves on board; and though we were not much affected by epidemical disorders, I find, by my journal of that voyage, (now before me,) that we buried Sixty-two on our passage to South-Carolina, exclusive of those which died before we left the Coast, of which I have no account. I believe, upon an average between the more healthy, and the more sickly voyages, and including all contingencies, One Fourth of the whole purchase may be allotted to the article of Mortality. That is, if the English ships purchase _Sixty Thousand_ Slaves annually, upon the whole extent of the Coast, the annual loss of lives cannot be much less than _Fifteen Thousand_. I am now to speak of the survivors.—When the ships make the land, (usually the West-India islands,) and have their port in view after having been four, five, six weeks, or a longer time, at sea, (which depends much upon the time that passes before they can get into the permanent Trade Winds, which blow from the North-East and East across the Atlantic,) then, and not before, they venture to release the Men Slaves from their irons. And then, the sight of the land, and their freedom from long and painful confinement, usually excite in them a degree of alacrity, and a transient feeling of joy—— The prisoner leaps to lose his chains. But, this joy is short-lived indeed. The condition of the unhappy Slaves is in a continual progress from bad to worse. Their case is truly pitiable, from the moment they are in a state of slavery, in their own country; but it may be deemed a state of ease and liberty, compared with their situation on board our ships.
