sound in the trees--a sound that died without an echo--and all was
still.

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. In the fleeting instant of his vision his imagination
had been so wrought upon by the apparent grace and ease and intention of
the marvelous performance that it did not occur to him that the line of
march of aërial cavalry is directly downward, and that he could find the
objects of his search at the very foot of the cliff. 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.

After firing his shot, Private Carter Druse reloaded his rifle and
resumed his watch. Ten minutes had hardly passed when a Federal sergeant
crept cautiously to him on hands and knees. Druse neither turned his
head nor looked at him, but lay without motion or sign of recognition.
