Before sunset, they reached the area of ashes where the ship had stood. Cochrane was sure that if anybody else had been left behind besides themselves, the landing-place was an inevitable rendezvous. Only three members of the ship's company had been inside when Babs and Cochrane left to stroll for the two hours astronomers on Earth had set as a waiting-period.

Anybody remaining would have come here. Nobody had. Babs and Cochrane were left alone.
