For an instant I stood transfixed. Then I made a hasty step to look over the verge of the rock. But in my surprise at his disappearance I forgot once more that we were on the moon. The thrust of my foot that I made in striding would have carried me a yard on earth; on the moon it carried me six⁠—a good five yards over the edge. For the moment the thing had something of the effect of those nightmares when one falls and falls. For while one falls sixteen feet in the first second of a fall on earth, on the moon one falls two, and with only a sixth of one’s weight. I fell, or rather I jumped down, about ten yards I suppose. It seemed to take quite a long time, five or six seconds, I should think. I floated through the air and fell like a feather, knee-deep in a snowdrift in the bottom of a gully of blue-grey, white-veined rock.

I looked about me. “Cavor!” I cried; but no Cavor was visible.

“Cavor!” I cried louder, and the rocks echoed me.
