The loss of slaves, through mortality, arising from the causes just mentioned, are frequently very considerable. In the voyage lately referred to (not the Leverpool ship before-mentioned) one hundred and five, out of three hundred and eighty, died in the passage. A proportion seemingly very great, but by no means uncommon. One half, sometimes two thirds, and even beyond that, have been known to perish. Before we left Bonny River, no less than fifteen died of fevers and dysenteries, occasioned by their confinement. On the Windward Coast, where slaves are procured more slowly, very few die, in proportion to the numbers which die at Bonny, and at Old and New Calabar, where they are obtained much faster; the latter being of a more delicate make and habit. The havock made among the seamen engaged in this destructive commerce, will be noticed in another part; and will be found to make no inconsiderable addition to the unnecessary waste of life just represented. As very few of the negroes can so far brook the loss of their liberty, and the hardships they endure, as to bear them with any degree of patience, they are ever upon the watch to take advantage of the least negligence in their oppressors. Insurrections are frequently the consequence; which are seldom suppressed without much bloodshed. Sometimes these are successful, and the whole ship’s company is cut off. They are likewise always ready to seize every opportunity for committing some act of desperation to free themselves from their miserable state; and notwithstanding the restraints under which they are laid, they often succeed. While a ship, to which I belonged, lay in Bonny River, one evening, a short time before our departure, a lot of negroes, consisting of about ten, was brought on board; when one of them, in a favourable moment, forced his way through the net-work on the larboard side of the vessel, jumped overboard, and was supposed to have been devoured by the sharks. During the time we were there, fifteen negroes belonging to a vessel from Leverpool, found means to throw themselves into the river; very few were saved; and the residue fell a sacrifice to the sharks. A similar instance took place in a French ship while we lay there.
