Sleeping? Perhaps, but certainly not all of them. Some of those plebes were as wide awake as the yearlings, and they were engaged in an occupation that would have taken the yearlings considerably by surprise if they had known it. There were seven of them in two tents, tents that were back to back and close together, one being in Company A and one in B.

They were very quiet about their work; for it was a risky business. Discovery would have meant the sentry's yelling for the corporal of the guard; meant that Lieutenant Allen would have leaped into his trousers and been out of his tent at the corporal's heels; meant a strict investigation, discovery, court-martial and dismissal. It was all right for yearlings to be out at night; but plebes—never!

It grew riskier still as a few minutes passed, for one of the B. J. beasts had the temerity to come out of his tent. He came very cautiously, it was true, worming his way along the ground silently, in true Indian—or Texas style. For Texas it was, that adventurous youth having vowed and declared that if he were not allowed to attend to this particular piece of mischief he would go out and hold up a sentry instead; the other three occupants were peering under the tent folds watching him anxiously as he crawled along.

As a fact, Texas' peril was not as great as was supposed, for the sentries had no means of telling if he was a yearling or not. The idea of a plebe's daring to break rules would not have occurred to them anyhow. Be that as it may, at any rate nobody interrupted the Seven Devils' plans. Cadet Powers made his way across the "street," deposited his burden, a glistening steel revolver some two feet long. And then he stole back and the crowd lay still in their tents and watched and waited.

They had not long to do that. Texas barely had time to crawl under the canvas and to mutter to his friends—for the hundredth time:

"Didn't I tell ye them air guns 'ud come in handy?"

At that very moment a sound of muffled laughter warned them that the moment had arrived.

"Just in time!" whispered Mark, seizing his friend by the hand and at the same time giving vent to a subdued chuckle. "Just in time. S-sh!"

The four, who lay side by side under the tent, could hear each other's hearts thumping then.

"Will it work? Will it work?" was the thought in the mind of every one of them.
