“Here comes Egan; we’ll ask him,” said Don.

The individual referred to was a first-class boy, and the first sergeant of Don’s company. When he was on duty he was a soldier all over; but during the hours of recreation he was as jovial and friendly a fellow as there was to be found about the academy.

“Say, sergeant,” said Don, not forgetting to salute, “what does a cadet do when he runs the guard?”

“What does he do?” repeated the sergeant. “Why, he spends a good portion of the next Saturday afternoon in walking an extra to pay for it.”

“I mean, how does he run the guard?” explained Don.

“Now, Gordon, isn’t that just the least bit—you know,” said the sergeant, laying his finger by the side of his nose and looking very wise. “You surely don’t expect me to tell you how it is done, do you? You had better ask Fisher or Duncan, or some of that crowd. They have had considerable experience in it.”

“We want to know what the meaning of the expression is,” said Bert.

“O, that’s it! Well, when a fellow slips out of his room, gets off the grounds without being caught, and comes back in the morning in time to fall in and answer to roll-call, we call that running the guard. By walking an extra we mean doing additional guard duty. The reason that Saturday is selected as a day of punishment is because the afternoon is given over almost entirely to recreation; but those who have been arrested while attempting to run the guard, or who have been caught in other acts of disobedience, are not allowed to take advantage of those hours of recreation, because they have already had their fun. Understand?”

Don said he did; and then he inquired who Cony Ryan was, and what he did to tempt the boys.

“Cony Ryan!” repeated the sergeant, his eyes growing brighter and a smile overspreading his face, as the memory of old times came back to him. “Why, he is a part of the academy, and I have seen the day when I thought we could not possibly get along without him. He keeps a neat little house down by the big pond, where he serves up the best pancakes I ever ate. His mince and pumpkin pies top the heap; and as for his maple molasses—ah!”
