"Old Joe seems to see everything that goes on, just as if he had a dozen eyes in his head," remarked Joel Jackman, who was also allowing a sub to take his place in the line-up.

"Well, that's what makes him the clever coach he is," Jack told him. "In his way he's like the old orchestra leader, Theodore Thomas. I've heard it said that when his orchestra of a hundred and twenty pieces was practicing some big movement by one of the great composers, Mr. Thomas would suddenly stop the music, and scold one player in particular. His wonderful ear had caught a note that was imperfect, and he had been able to pick out the chap who was guilty. Well, that's the way with our Joe; only in this case it's his eye that is highly educated, instead of his ear."

Joel moved aside with Jack.

"Listen to me, Jack," he went on to say, impressively. "Some of the boys here chanced to mention the fact that last year a Harmony fellow tried to steal the signals of Marshall, and in fact did so; but the other fellows discovered him watching the play from a tree or some place, and they just changed their code of signals after he had been scared away. Now, Jack, don't look surprised when I tell you I've got a sneaking notion we're being spied on right at this very minute!"

Jack saw that Joel was not joking, and he looked serious.

"What makes you say that?" he inquired, immediately.

"I haven't mentioned anything about the matter to the fellows; in fact, I only got on to the game about the time you dropped in. Just turn to the right a little, will you, Jack. I'm not pointing, because it would tell the skunk we knew about his being there. See that bunch of trees over yonder, do you? Pretty thick, all right, and offering a splendid asylum to any chap who might want to watch what we were doing out in the open field. He's up in the largest tree, that's right."

"Did you see him then, Joel?" asked the other, after staring for a brief interval in the direction indicated, without noticing any incriminating evidence.

"Well, no, I can't say that I did, though it seems to me there is something like a bunch in that crotch about ten feet from the ground; but the branches sort of screen it. But, Jack, I saw the sun flash from the lens of a pair of glasses, not only once but several times."

Jack continued to watch. This sounded like serious business, and he began to feel something like indignation surging up within him. If there was anything Jack Winters despised it was underhand work. Straight and aboveboard himself he was unable to conceive how any fellow could so demean himself as to wish to win by trickery.
