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 arial 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.
"Did you fire?" the sergeant whispered.
"Yes."
"At what?"
"A horse. It was standing on yonder rock--pretty far out. You see it is no longer there. It went over the cliff."
The man's face was white, but he showed no other sign of emotion. Having answered, he turned away his eyes and said no more. The sergeant did not understand.
"See here, Druse," he said, after a moment's silence, "it's no use making a mystery. I order you to report. Was there anybody on the horse?"
"Yes."
"Well?"
"My father."
The sergeant rose to his feet and walked away. "Good God!" he said.
