The officer rose to his feet, trembling. The familiar sensation of an abraded shin recalled his dazed faculties. Pulling himself together he ran rapidly obliquely away from the cliff to a point distant from its foot; thereabout he expected to find his man; and thereabout he naturally failed.

A half-hour later he returned to camp. This officer was a wise man; he knew better than to tell an incredible truth. He said nothing of what he had seen. But when the commander asked him if in his scout he had learned anything of advantage to the expedition he answered:
"Yes, sir; there is no road leading down into this valley from the southward."
The commander, knowing better, smiled.
