Jack and Bert came bursting in, having heard from George that Tom was back.

"Any luck?" asked Jack, for they knew of Tom's trip to the drug store.

"Well, in a way, yes, and yet not. I found out who bought the poison."

"Was it Sam Heller?" asked Bert eagerly.

"No," answered Tom. "Haven't I told you that I'm sure he hadn't any hand in it?"

"You wait and see," advised Jack. "I think you're away off, Tom. But say, you want to come out to football practice this afternoon. Strict orders for everyone to be on the job."

"Oh, what's the use?"

"Lots! What's getting into you lately?" asked Bert.

"Oh, you know how it is. Sam is sure to try to make a fumble for me; and what's the fun of playing when you don't know what minute you'll lose the game?"

"Why don't you complain of him to Morse, or Mr. Jackson?" asked Jack.
