For nearly a half an hour the O.C. lay awake, reviewing the method he had followed in questioning Cadet Prescott.

In the morning, after breakfast, there were a few minutes of leisure in camp before the squads or platoons marched away for the first drills.

"You were on the grill, last night, old ramrod?" asked Furlong, in a chuckling whisper.

"Yes," d.i.c.k nodded.

"You couldn't tell anything?"

"I knew less than nothing to tell."

"You didn't see us, last night, as we slipped away from the monu-----"

"Shut up, you sun-scorched idiot!" cried Prescott sharply, under his breath. "I don't want to know anything about it now."

"Oh, that's all right, I suppose," said Mr. Furlong, looking furtively towards Bert Dodge, who was standing some distance off.

The very thought that he was now practically certain, morally, at least, who one of the perpetrators of the monument affair was, made d.i.c.k uneasy. He knew there was still a danger that he and Greg might be summoned again to the tent of the O.C.

Bert Dodge saw, from a distance, the whispered talk between d.i.c.k and Mr. Furlong; he also saw the latter's quick, stealthy glance.

Now, Dodge, from having tried to visit Furlong the night before, knew that the young man had returned from the hop, for he had seen Furlong go into his tent shortly after ten. Dodge also knew that Furlong had been absent from camp at the time of the monument discharges.

"Furlong is one of the offenders," thought Bert, "and Prescott is roasting him about it. I suppose our highly conceited cla.s.s president thinks it his place to lecture all the jokers in the cla.s.s. But how would it be possible, without getting myself into trouble, to pa.s.s on the hint that Prescott knows more than he is telling?"

It didn't take a fellow with all of Cadet Dodge's natural meanness very long to invent a plan that looked feasible.

Sauntering along near the guard tent, Dodge encountered a cla.s.smate with whom he was on fairly good terms, Mr. Harper, who was waiting to fall in when the next relief of the guard was called.

"Prescott was on the grill last night, I hear," began Bert.

"So I hear," nodded Harper.

"I guess he dodged the O.C. cold," chuckled Dodge.

"He denied any knowledge of the monument business, I've heard,"

replied Harper.

Bert chuckled.

"That sounds like old Prescott," laughed Bert. "And I'll bet he managed it without telling any lies. I know Prescott of old.

Our family once lived in the same town with him, you know. Prescott was one of the biggest jokers in our High School. And he never got caught in those days. Prescott was always the artful dodger."

"What do you mean by that!" asked Harper. "You don't mean that Prescott is untruthful."

"Oh, no, not at all," laughed Bert. "But, if I could put him on the rack, and get the whole thing, unreservedly, out of Richard Prescott, I'd be willing to bet, in advance, that he knows just who set off the cannon crackers last night."

Dodge was careful not to speak so that he could be overheard by Prescott or Furlong, yet he was certain that, on the still morning air around the guard tent, his voice was carrying sufficiently to penetrate to the other side of the khaki walls of the O.C.'s tent.

"Prescott is the clever one, and the loyal one to all but tacs.,"

laughed Bert to Harper, as he strolled away. Dodge hoped that the O.C. was in his tent.

It is true---Captain Bates was there. Having drawn the flap, and being in the act of enjoying his morning newspaper, the O.C.

heard.

"Hang it, I felt last night that, while answering me truthfully, Mr. Prescott was proving the possession of sufficient cleverness to keep me off the monument trail, just as he foiled my catching Mr. Holmes," mused the O.C. "And I said as much last night to Colonel Strong."

At that moment the flap of the tent was lifted and the K.C. returned the salute of his subordinate, who had promptly leaped to his feet.

In a few swift, low words, Captain Bates repeated the conversation he had just overheard.

"That bears out what you thought last night, Bates," rejoined the K.C.

"I think there is nothing for it but to have Mr. Prescott in here and put him on the wheel again. Rack him, Bates!"

"I've just time, Colonel to catch Mr. Prescott before the drill squads go out. Corporal of the guard!" hailed the O.C., looking out from his tent.

In another moment a very erect young member of the guard was striding around the head of the encampment, and then down one of the company streets. d.i.c.k, in front of his tent, in field uniform, received the summons and responded at once.

"Caught him!" quivered Bert Dodge. "No if that infernal humbug will get hot-headed and answer the O.C. rashly, there may be something good coming in the punishment line! It would be a source of wild joy if I could get d.i.c.k Prescott on the wrong flank with the tacs.!"

The instant that d.i.c.k reported, and found himself in the presence of his two inquisitors of the night before, he knew that some hint of his new knowledge must have reached the tactical department.

"Mr. Prescott, last night," began Captain Bates, "you denied absolutely having any knowledge as to the persons who set off firecrackers near Battle Monument."

"Yes, sir."

"I have since gained good reason to think," went on the O.C., "that you know who at least one of the perpetrators was."

Mr. Prescott remained silent.

"Why do you not reply, Mr. Prescott?"

"I didn't understand, sir, that you had asked me a question."

Captain Bates flushed. He hadn't asked a question, in question form, and he saw how neatly this cadet had "caught" him. But that only served to increase the suspicion of both officers present that Mr. Prescott was a very clever witness who was successfully contriving to keep something back.

"Mr. Prescott, do you now know who was responsible for the monument affair of last night?" insisted the O.C.

"I don't know sir," replied d.i.c.k, putting all proper emphasis on the word.

"Yet you suspect?"

"I suspect one man, sir," d.i.c.k responded without attempt at concealment.

"Is the one you suspect a cadet?"

"Yes, sir."

"His name?" broke in Lieutenant Colonel Strong.
