“No sleep for me tonight, I wager,” said Blake; but somehow he seemed to glory in the fact rather than put on a doleful expression. Action meant a fresh possibility for a successful ending of his search.

Hugh looked around him. The camp of the guardsmen still presented a wonderfully fascinating picture in his eyes, even though some of the tired militiamen had sought their tents in order to try and get a little sleep, having had their rest broken more or less since leaving their widely separated homes.

“There’s the captain heading this way now!” exclaimed Bud, with sudden zeal. “P’r’aps we had better tackle him while we have the chance, Hugh. He’s got a heap of camp duties to look after, and, according to military rules, they’d have to take precedence above any private business.”

“Come on, then, and we’ll start the ball rolling,” the scout master agreed.

When Captain Barclay saw his trio of boy friends from Oakvale heading toward him, he smiled amiably, and nodded his head.

“Any good news, boys?” he immediately asked, showing that he still remembered about their mission; “heard of Felix Gregory anywhere, and was he visiting in some other part of the camp?”

“No, sir, nothing can be learned about him from any of the men,” replied Hugh, and then immediately adding: “Our chum here, Bud Morgan, happened to learn something that we believe may offer a strong clue.”

“Tell me about it, then,” the officer commanded. “I’m very interested in the result of your noble mission; and this strange disappearance of an enlisted man from camp is bothering some of us. I haven’t mentioned it to any one higher up, but was just thinking of seeing the general about it. Things like that reflect upon the management of a military camp, where it is expected that discipline governs every movement, so that it would appear to be impossible for a single individual to drop out. Now proceed, please.”

Hugh told the story, giving Bud due honors for having made the wonderful discovery that Luther Gregory was hovering near by, evidently bent on sharing some of the foul work with the man whom his money had hired.

Captain Barclay asked several sharp questions. It could be seen that he was intensely interested. Bud made haste to enlighten him on the points that did not appear to be quite clear in his mind.
