"Captain Davidson, I have here under arrest, this young man with these two others as witnesses."

"Of what are they accused?" asked the officer, as he glanced sharply at the three of them.

"Of espionage," said the soldier.

"Of espionage?" said the officer. "That is a serious offense."

"I know it is but that is the term under which the offense comes," replied the soldier.

"This must be taken up by the Commandant himself," said the Captain, as he touched a bell at his side. Immediately a young officer appeared.

"Captain Abercrombie, tell Major-General Norris, the Commandant, that we have here a prisoner accused of espionage."

The orderly saluted and was soon lost to view behind a door at one end of the hall. He was back in a few minutes. During that time, our three adventurers stood and watched with interest the varied scene that was taking-place before them.

"This is some lark," said Bill to Bob in a low tone.

"No communication between the prisoner and witnesses," said the Tommy at once, as he moved nearer as if to enforce his demands. Pud looked over at Bill with a sort of reproach in his eyes, for he had heard the remark. Bob kept his eyes front for he was very much interested in the comings and goings of the officers, orderlies and soldiers that came and went throughout the hall.
