I called, and called, but could get no answer.

Presently I heard a groan that seemed to come out of the bowels of the earth; but, as yet, I could not make out where he was.

Going back to camp, I procured a light, and after whooping and hallooing for a long time, I heard another groan, this time much louder than before.

The voice appeared to be overhead.

There was no tree or house to be seen; and then again the voice seemed to answer from under the ground, in a hollow, sepulchral tone, but I could not tell where he was.
