"And what's this I hear about playing a joke on Tom Fairfield, and some of his friends?" asked another voice.

"A joke!" gasped Tom.

"Quiet!" warned his friend.

"Ha! Ha!" laughed Sam. "Yes, it was a joke all right. You know those fellows happened to go camping near where Nick and I were. We met old Skeel—you know, the prof. who used to be here. Well, he had some scheme of finding a hermit's money hidden in the old mill, and we went in with him. Then we found that Tom and his crowd were on the same trail.

"Nick and I decided to have some fun with 'em. So one day we sneaked into their camp, when Tom was out, and just took Bert, Jack and a fellow named Dick something-or-other prisoners. Say! but they did kick and struggle, but we managed 'em.

"We carted 'em off to the old mill, and there we put 'em in a secret room. It was jolly fun, until Tom came, made quite a row, and got 'em out. But it was all a joke."

"By Jove! and a good one, too!" cried several laughing voices.

"Did you get the treasure?" someone wanted to know.

"Yes, it was there all right. The old hermit got it. I don't know just how that was, for Nick and I left. But I think Tom and the old chap had a row, and part of a wall fell down, showing a secret room. Oh, but you should hear how indignant Jack and Bert got when they found we were standing guard over them! It was as good as a hazing."

"It must have been!" agreed his friends, laughing heartily.
