He moved away the bench, and then we saw that it stood on a wooden trap-door.

He took hold of a ring, and lifted up this door, and there was a round hole about as big as the hind wheel of a carriage.

It was like a well, and was as dark as pitch.

When we held the lamp over it, however, we could see that there were winding steps leading down into it.
