“Were you never caught at it?” inquired Bert.

“Once or twice, but that was owing to our own carelessness. It is an easy thing to do when the right kind of fellows are on duty, and really exciting when the posts are held by such boys as Blake and Walker, and others of that sort. They’re a mean set. They are always on the watch for a chance to report somebody, because they believe that that is the way to gain the good-will of the teachers.”

“And a packed knapsack,” continued Clarence, “is one with something heavy in it, such as bricks or paving-stones. When you are called upon to walk an extra, you have to pace up and down your beat for four hours with that knapsack on your back and a musket on your shoulder.”

“That can’t be very pleasant,” observed Don.

“Well, I am free to confess that it isn’t,” returned Clarence, “and it is all owing to the way the thing is managed. If they would let us perform the extra duty while the rest of the boys were drilling, or while the class in geometry was reciting, I should not mind it in the least. But you see they won’t do that. We have to work hard all the week, and walk our extras on Saturday afternoons during the hours that are given to the good little boys for cricket, ball-playing, fishing, target-shooting and recreations of that sort.”

“But overstaying our time was not the only offence of which we were guilty last night,” said Don, after a moment’s pause. “When we reached our room we struck a light, and I suppose we shall be reported for that.”

“Of course you will,” said Fisher. “You had no business to have a light in your room after taps.”

“But we didn’t think,” said Bert. “And, besides, we wanted to read our pass, so that we might know just what we had done that was wrong.”

“No odds,” exclaimed Clarence. “No excuse will be accepted. You will probably be gated for a month.”

“But you need not submit to the restriction of your liberty unless you feel like it,” chimed in Fisher. “Do as all the best fellows in school do—run the guard, and have a good time in spite of the teachers.”[teachers.”]
