In the vessel of eleven tons, the length of the room for the thirty slaves was twenty-two feet.

The greatest breadth of the floor was eight, and the least four.

The whole height from the keel to the beam was but five feet eight inches, three feet of which were occupied by ballast, cargo, and provisions, so that two feet eight inches remained only as the height between the decks.

Hence, each slave would have only four square feet to sit in, and, when in this posture, his head, if he were a full-grown person, would touch the ceiling, or upper deck.
Having now received this admeasurement from the builder, which was rather more favourable than my own, I looked upon the destination of these little vessels as yet more incredible than before.

Still the different persons, whom I occasionally saw on board them, persisted in it that they were going to Africa for slaves, and also for the numbers mentioned, which they were afterwards to carry to the West Indies themselves.
