"Have you any explanation to offer, Mr. Durville?" asked Lieutenant
Denton in his official tone.

"None, sir."

"Very good, Mr. Durville. You will go to your room and remain in close arrest until you receive further official communication in this matter."

"Very good, sir."

Durville spoke in steady, if icy tones, as he saluted and made this response.

"That is all, Mr. Durville."

"Very good, sir."

Like one frozen, the cadet in unfamiliar attire turned and left the office.

"How did you happen to make the discovery, Mr. Prescott?" gasped the O.C.

"I discovered, sir, that I had overlooked this report, which I now turn in, sir," Dick replied rather hoarsely. "It was just as I was about to leave the sub-division that Mr. Durville came in. I had no alternative but to report him, sir."
