"Oh, Jack! suppose he should attack you some time when you weren't aware?"

"That's a risk a fellow has to run. Of course, I expect to keep on my guard, not only against Gabe Werner but also against Martell, Brown and Glutts. The whole four don't like any of our crowd."

"But just read the dreadful thing he says," continued the girl, as she caught Jack tightly by the arm. "He says he'll pound your face into a jelly! Oh, Jack! don't you ever give him a chance to do that," and Ruth's face showed her solicitude.

"There is one thing you have to remember, Ruth, and that is the writer of an anonymous letter is generally a coward," Jack answered as lightly as he could, more to ease her feelings than anything else. "So don't you worry about this letter. Have you mentioned it to any of the others?"

"No; I didn't want to worry them."

"I'm glad you didn't say anything to Martha and Mary. I know it would upset them a good deal, and maybe they would think they'd have to write to their mothers about it. Just keep it to yourself. And please don't destroy that letter; it might come in useful some time. Maybe we can trace the handwriting."

"But you'll tell your cousins at the Hall, won't you?"

"Yes; I think I had better, so that they can be on their guard, too. We don't want to run any unnecessary chances when it comes to those rascals." And there the talk on this subject came to an end.

It was not until late that evening, when the four Rovers were retiring, that Jack got a chance to mention the anonymous letter to his cousins. All were tremendously interested, and speculated on who the writer could be.

"My opinion is it was either Gabe Werner or Slugger Brown," said Randy. "Neither Nappy Martell nor Bill Glutts would have the nerve to do it."
