"Now, one thing that all you youngsters want to remember," declared Len, "is that no player can play off-side. All ready?"

Both young football captains called out that they were. Len had provided himself with a pocket whistle loaned by one of the fifth-grade boys.

Trill-ll! Tom Craig kicked the ball himself, but it was a poor kick. The pigskin soon struck the ground.

"I'll try that over again," announced Tom.

But Dick and his own fighting line had already started. Dick, at center, with Dave on his right hand and Greg Holmes on his left, snatched up the ball and started with it for the Rustlers' goal.

A bunch of Rustlers opposed and tackled Prescott. Dick succeeded, by the help of Dave and Greg, in breaking through the line, but the Rustlers turned and were after him. Down went Dick, but he had the pigskin under him.

"Take it away from him, fellows!" panted Craig. But Len blew his whistle, following up the signal by some sharp commands that brought the struggle to a close.

"Prescott's side have the ball," declared Len, "and will now play off a snap-back. And, boys, one thing I must emphasize. I've told you that under the rules no man may play off-side. So, hereafter, if I find any of you off-side, I'm going to penalize that eleven."

Dick was whispering to some of his players, for, without any code of signals, he must thus instruct his fellows in the play that was to be made with the ball.

Then the whistle sounded. The Rangers put the ball through the Rustlers' line, and onward for some fifteen yards before the ball was once more down.
