think it is Miss Rockwell."

"It is, and Miss Feversham is with her, and so is Mr. Rockwell,"
answered Dave, and then the boys took off their caps in salutation. And
then they recognized a number of other friends.

The eleven had just turned into its dressing-room, to prepare for the
game, when Chip Macklin came running in all out of breath.

"I want to see Dave!" he gasped, and then, as soon as the pair had
walked to a corner, he went on: "I caught Nat."

"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!"

CHAPTER XX

THE GREAT GAME WITH ROCKVILLE

"Dave, I think I see a chance of catching Rockville napping," said
Roger, just before the practice began.

"You mean, if they try to take advantage of our signals?"

"Yes. If they feel sure we are going to do one thing and we do another,
they'll get left."

"Well, they'll deserve to get left--if they try to profit by any such
work."

"Maybe the eleven won't stand for it."

"Oh, I don't know. Rockville is hungry for a victory over us, and they
may think all is fair in love and war and football," broke in Phil.

As each eleven came on the gridiron it was roundly cheered. The
Rockville supporters at once commenced
