Dick was about to ask Don if he was the boy who tried to bury himself out of sight in a snowdrift, and who jumped up and ran toward the academy when the corporal of the guard was summoned; but he was interrupted by a look from Duncan. Then the latter pointed with his thumb over his shoulder, and Dick, who understood the motion, beat a hasty retreat, looking crestfallen as well as bewildered.

“He committed a most inexcusable blunder, and came very near getting the whole of us into hot water,” said Fisher, who knew that he must offer something in the way of explanation. “We will give him a good talking to, and make him promise to be more careful in future. Now, Gordon, how in the world did you get in?”

“Easy enough,” answered Don. “I say, boys, there’s lots of fun in running the guard, and some little excitement too. I am ready to try it again any night. Come on, and I will tell you all about it.”

The three boys linked their arms together and walked toward an unfrequented part of the grounds, so that Don could give the details of his exploit without danger of being overheard. We will tell the story in our own way.

CHAPTER VIII.
HOW DON GOT IN.

“Don’t be in too great a hurry. Let me get out of your sight,” said Clarence Duncan, as he crept through the fence; and Don, whose suspicions had not been aroused, was careful to obey. When he thought that Clarence had been allowed time to reach the academy, he passed through the opening and moved toward Dick Henderson’s post. He saw the latter when he came out from behind his box and walked along his beat, and remembering Tom Fisher’s words of caution—that it would not be safe to approach Dick’s post openly for fear that the officer of the day or the corporal might be somewhere within sight—Don sought concealment by throwing himself at full length in the snow. He expected to see Dick turn about and go behind his box again; and consequently he was not a little amazed when the sentry took up a position directly in front of him, and called for the corporal of the guard.

Don did not know what to make of it; but he did know that if he stayed where he was, detection and punishment were inevitable. He still had one chance for escape, and he lost no time in improving it. He jumped up and took to his heels, trusting to the darkness and to his uniform to conceal his identity. He was very light of foot, and by doing some of his best running, he succeeded in dodging around the corner of the academy building just as the corporal threw open the door of the guard-room. The signal, which had produced such an effect upon Dick Henderson, he had given by the merest accident. It was one that Fisher, by some oversight, had neglected to teach him, although he had let him into the secret of all the other signs and pass-words.

“A miss is as good as a mile, but still that was a pretty close shave,” said Don to himself, as he opened the back door and felt his way up the stairs. “I can’t understand why Dick challenged me, unless it was because my approach was discovered by somebody else who would have reported him if he hadn’t tried to stop me.”

On reaching the second landing Don moved cautiously along the hall, spelling the last syllable of the pass-word as he went. Greatly to his surprise, he met with no response. When his hands came in contact with the door, he began searching for the knob; but when he turned it, the door did not open for him. It was locked.

“Now here’s a go,” thought Don, who did not know whether to laugh or get angry over the predicament in which he so unexpectedly found himself. “Where’s Fisher? He knew very well that I couldn’t get to my room without assistance, and yet he has deserted me. If that is the sort of fellow he is, he’ll not eat any more pancakes this winter at my expense.”
