"I was taught this morning that when an officer passed along in rear of the post without attempting to cross it, simply to stand at a carry, facing outwards. I never heard of its being done any other way."

"Ho, ho!" laughed Benny. "Why, the very first thing a soldier's taught is to look towards the officer he salutes, and never to turn his back. Ain't it so, Mr. Cross?" he asked, confidently and appealingly of the corporal of the guard, who had arisen, listening with a grin on his face while pulling on his gloves.

"You have a heap to learn yet, young man," was the withering reply. "A sentry always faces outward in camp when an officer passes by, even if he passes behind his post, in which case he doesn't even salute. I gave Mr. Graham those orders myself, sir."

Pops was wise enough to hold his peace, and never admit that he knew it all before; nor did he join in the burst of laughter at Benny's expense. Frazier, indignant, discomfited, shamed again before them all, glared wrathfully at his tent-mate, as though it were all his fault.

But it would never do to let a plebe come off with such flying colors, argued Mr. Woods, of the yearlings. One after another, insistently, he pressed Geordie with all manner of points in sentry duty, and all that were not broad burlesque were answered correctly, though it was evident that Pops was getting annoyed. At last, just before the order to rise was given, the yearling leaned half-way across the table.

"Now, suppose I was to come, sir, in the dead of night to your sentry post, and demand, as your superior officer, that you give me up your gun, what would you do?"

There was strained silence among the plebes for a moment. Geordie's blue eyes, blazing a little, were looking straight into the frowning face of his tormentor.

"Do you mean without the countersign? Without being an officer of the guard?"

"Exactly, sir. Simply as your superior officer—as an old cadet to a plebe, sir."
