"What doing?" demanded Dave, quickly.
"Giving all of your signals away to Merwell, Jasniff, and one of the Rockville football players. He started to tell about your trick plays when he saw me standing near, and shut up."
"Where is he now?"
"In the grandstand, with some girl."
"I will attend to this at once, Chip. Come with me."
Dave led the small student out of the dressing-room, and called Andrew Dale and Mr. Dodsworth. Quickly the situation was explained. The school teacher looked shocked, and the gymnastic instructor was disgusted.
"I will take care of Poole," said Mr. Dale, in a strained voice. "Mr. Dodsworth, you had better arrange for a change of signals."
"I will," answered the gymnastic instructor. And then Andrew Dale hurried off, and Dave returned to the dressing-room, accompanied by Mr. Dodsworth. The signals were re-arranged, and so were the signs for some of the new trick plays.
"Now then, boys, let me give you a bit of advice," said Mr. Dodsworth, when they were ready to go out on the field for practice. "From what I have heard Rockville has good staying powers, and will try to tire you out. Your move is to go at them with a jump and make your points early in the game—and then hold them down. Now do your best—and don't give in until the last whistle blows!"
