It was, as I have said, a pit, with sharply-sloping walls and a level bottom about twenty feet across. This bottom was littered with great gobbets of flesh, most of which was in the last state of putridity. The atmosphere was poisonous and horrible. After tripping and stumbling over these lumps of decay, I came suddenly against something hard, and I found that an upright post was firmly fixed in the center of the hollow. It was so high that I could not reach the top of it with my hand, and it appeared to be covered with grease.
