There before us was a wall of rock, of which the lower parts were here and there clothed in grasses, lichens, and creepers.

I walked along it, calling at the top of my voice.
Presently my heart stood still, for I thought I heard a faint answer.

I drew nearer to the place from which the sound seemed to come, and again called.

Yes, there was an answer in my wife's voice.

It seemed to come from the rock.
