All right now!" Steve was glad they had the gridiron practically to themselves, for he cut a poor figure the first three times that he tried to reach the elusive quarter-back.

Once Marvin caught him with a straight arm and sent him toppling out of his path, once Marvin dodged him completely, twirling on one heel and darting past him beyond reach, and once the little quarter-back wrenched himself loose after being tackled.

But the fourth time Steve was more successful, and after that he reached the runner every time even if he didn't always stop him short.

Even when Steve had his arms gripped tightly about Marvin's knees, the latter was almost always able to somehow make another yard or two before he was willing to call "Down!" But Steve learned more in that half-hour than he had learned all the season, and when, after awhile, the two boys, panting and perspiring but satisfied with themselves, walked back to the gymnasium, Steve had the grace to thank Marvin.
