"We couldn't follow that on our feet," I declared, returning to the shore. "But it does look promising. At ten miles an hour we'd reach the western slope in four hours. Four hours to sunshine—but it might as well be four hundred. It's impossible."
We turned then and retraced our steps to our camp, if I may give it so dignified a title.
