one is made fast to the ancle of his next companion. Yet even thus secured, they do often jump into the sea, and wave their hands in triumph at the approach of death. E is a thumb-screw. The thumbs are put into two round holes at the top; by turning a key a bar rises from C to D by means of a screw; and the pressure becomes very painful. By turning it further, the blood is made to start; and by taking away the key as at E, the tortured person is left in agony, without the means of helping himself, or being helped by others. This is applied in case of obstinacy, at the discretion of the captain. I, F, is a speculum oris. The dotted lines represent it when shut; the black lines when open. It opens at G, H, by a screw below with a knob at the end of it. This instrument was used by surgeons to wrench open the mouth in case of lock-jaw. It is used in slave-ships to compel the negroes to take food; because a loss to the owners would follow their persevering attempts to die. K represents the manner of stowing in a slave-ship.

In vessels that sail from Bonny, Benin, and the Calabars, whence a large proportion of slaves are brought, this mortality is so much increased by various causes, that eightysix in a hundred die yearly. He adds, "It is a destruction, which if general but for ten years, would depopulate the world, and extinguish the human race."
We next come to the influence of this diabolical system on the slave-owner; and here I shall be cautioned that I am treading on delicate ground, because our own countrymen are slave holders. But I am yet to learn that wickedness is any the better for being our own.—Let the truth be spoken—and let those abide its presence who can.
The following is the testimony of Jefferson, who had
