"We are not afraid of you," said Phil, firmly. "We've told you that before. We intend to leave you alone, and the best thing you can do is to leave us alone."

"Bah! I know you, and you can't fool me! You say one thing to my face and another behind my back. But don't you dare to say too much; and you can tell Shadow Hamilton not to say too much, either. If you do—well, there will be war, that's all—and all of you will get what you don't want!" And with this threat, Gus Plum hurried around a corner of the school building and out of sight.

"What a cad!" murmured Phil.

"He is worked up; no disputing that," was Roger's comment. "He acts as if he was afraid something was being told that he wished to keep a secret."

The hot blood had rushed to Dave's face, and he was still trembling.

"I wish I had knocked him down," he said in a low tone.

"What good would it have done?" returned Roger. "It would only get you into trouble with the doctor, and that is just what Plum would like. When it comes to a standing in the class, he knows he hasn't as much to lose as you have. He is almost at the bottom already, while you are close to the top."

"But, Roger, he said—oh, I can't bear to think about it! I suppose he blabs it to everybody, too, and they will think——"

"Don't give it another thought, Dave," said Phil, soothingly, and he turned his chum toward the river again. "Dismiss Plum and all his meanness from your mind."

"I wish I could," answered Dave, and his voice had a great deal of seriousness in it.
