Here they found boxes containing nippers, chisels, and other instruments such as are used to undo the irons upon slaves.

Also they found the keys of the padlocks that locked the iron bars to which the captives were tethered.
Taking a lantern with them, but leaving another burning as before in the hut, lest its absence should excite suspicion, they passed through two strong gates and down the steps on the further side of the embankment.

A few paces beyond stood the first slave-shed, a rough erection supported on posts, but without sides.
They entered the shed, Otter leading the way with the lantern.

In the middle of it was a path, and on either side of this path ran the long bars to which the captives were fastened in a double row.

Perhaps there might have been two hundred and fifty of them in this shed.
