“But what puzzles me is how Clinton can help knowing it when you change the liniment. As soon as he uses it he’ll see that something is wrong, and he’ll recall that you were in the room.”

“Oh, no, he won’t. You see, the two liquids are so nearly alike that it’s hard to tell the difference. Then, the beauty of it is that the one I’m going to put in place of his regular liniment doesn’t take effect for twelve hours. So he’ll never connect me with his trouble.”

“All right. It’s up to you. But come on, let’s get out on the road again. I don’t fancy tramping through the woods.”

They emerged at a point some distance back of Tom and Sid, who continued their walk.

“Did I tell you I met Langridge and Gerhart the night I went to see Phil’s sister?” asked Tom after a pause.

“No. What were they doing?”

Tom related the conversation he had heard, and gave his speculations as to what Gerhart could have meant.

“I guess he’s counting on Phil being laid up so long that he can have his place at quarter-back,” was Sid’s opinion, and Tom agreed.

The specimens of unfortunate frogs, to be used in biology, were stowed away in a box Sid carried, and then he and Tom turned back to college. That night they went to a rehearsal of the glee club.

“Do you mind staying alone, old chap?” asked Tom of Phil as they prepared to depart.
