“Would you know the fellow if you were to see him again?” questioned George, frowning.

“I don’t know. I think so, although I saw his face only for a second.”

“How was he dressed?”

“He had on a pair of shoes, heavy ones,” was Sam’s innocent reply.

“What kind of suit?” persisted George.

“Didn’t notice it. Don’t think I saw it at all.”

“Boys, this is serious,” declared Captain Baker, turning to his fellow Tramps. “Some one has been spying while the girls were at practice. We should have posted guards, but I didn’t think we should be bothered this afternoon. There are some queer people around here. Of course, we can’t blame them for wanting to know all they can, but we may blame ourselves for letting them find out. We shall see to it, however, that this incident is not repeated.”

“I wonder if he saw our signals!” gasped Jane.

“He did, no doubt. We were making them about that time. But, girls, keep your eyes open. If the boys don’t catch the guilty ones, we shall undoubtedly do so when we get in the tournament. If this spying has been done in the interest of any of the players, the girls will know our signals when we face the net,” declared Harriet. “The spy may not have heard our explanations, but if he is sharp he will be able to identify the signals with the plays that follow. When any of you sees that her opponents understand our signals you will know you are getting close to the fellow who hurt Sam’s nose. Then you just watch. Are you going to send him to a doctor, Miss Elting?”

“I’ll take him in the motor car,” said Jane.
