"Why the oar itself—the one Mr. Layton cut for him. You see," added Scotty, so eager to get through with what he had to say that he could scarcely speak plainly, "about half an hour ago, as I was going through the hall, who should come in but Bob Nellis and three or four of his particular friends. Bob carried an oar in his hand, and I saw that it was one of the new ones he had just received, and that the leather had been removed. If I needed any other evidence to convince me that he knew just what had been going on I should have had it in the look his face wore and the words he uttered. I heard him say, as he went up the stairs, 'There's not another boy in school who would have put up with that Gus Layton's meanness as long as I have, and I'm not going to do it any longer. If anything about our boat breaks during the race to-day I shall believe it is because he has tampered with it in spite of our watchfulness, and I shall come back here and expose him in the presence of the professors and of the students.'"

"Well?" said Simpson, when Scotty paused to take breath.

"Well, they went up to their dormitory, and presently I heard a door slammed and locked. They have hidden the oar in their closet; and I propose that, if we can get at it, we take it out and hide it somewhere else. Then we'll watch our chance and tell Gus of what we have done, and suggest to him that if there is any row raised all he has to do is to deny the whole business, for there is no evidence against him—eh?"

"But Gus can't keep a secret, you know," said Simpson, unconsciously making use of almost the very words that one of Johnny's friends had addressed to himself, "and perhaps he has told some of the fellows that his father cut the oar."

"I know he has. He has told you and me and all the rest of his friends; but we will not blow on him."

"I—ah—that is—oh, no, of course not," stammered Simpson, his heart fairly coming up into his mouth when he reflected that he had already committed the secret to half a score of boys who would not countenance any such trickery as this which Gus and his father had been guilty of.

"See here, Simp," said Scotty, looking suspiciously at his friend, "that doesn't come from the heart. Are you White?"

"Not much. I am so Blue it will rub off."

"Then you had better do something to prove it. You must help me get that oar. I have tried all my keys, but none of them will fit the lock. Here's something, however, that will open the way for us," said Scotty, producing from under his jacket a large chisel which he had abstracted from the carpenter's chest. "If you are Blue clear through, as you say you are, take this and burst open the door."

Simpson, eager to prove himself true to his colors, replied by seizing the chisel and running out into the hall, Scotty following close at his heels. A few rapid steps carried them up the stairs to Bob's dormitory, and a few more to the closet in which the telltale oar was hidden. Here Simpson's courage began to fail him, and he felt the strongest desire to back out.
