In the middle of the door was a large staple with a rusty chain, like an ox-chain, for fastening a victim down.

When the door had been opened after the death of the late proprietor, my informant said, a man was found padlocked in that chain.
We found also three pairs of stocks of various construction, two of which had smaller as well as larger holes, evidently for the feet of women or children.

In a building near by we found something far more complicated, which was perfectly unintelligible till the men explained all its parts: a machine so contrived that a person once imprisoned in it could neither sit, stand, nor lie, but must support the body half raised, in a position scarcely endurable.

I have since bitterly reproached myself for leaving this piece of ingenuity behind; but it would have cost much labor to remove it, and to bring away the other trophies seemed then enough.

I remember the unutterable loathing with which I leaned against the door of that prison-house; I had thought myself seasoned to any conceivable horrors of Slavery, but it seemed as if the visible presence of that den of sin would choke me.
