"Oh, one out of which we can get some sport and humiliate him at the same time. I am sure you do not want to fight with the fellow?" "I have been thinking that I would be ashamed to have an encounter with him." "Exactly so. Now, I know you are not much of a fellow for pranks, but I hope you will agree to this little scheme of mine." "State it," said Jack, rather doubtfully. "Well, you know Thornton considers himself something of a masher. He gets stuck on every pretty girl who smiles on him." "Yes." "Danny Griswold is a daisy as an impersonator of girls. You know he is to play a girl's part in one of the entertainments to be given in the fall. He has done the trick before, and he sent home for his outfit a week ago. Yesterday, while Rattleton and I were cramming for recitations the door opened, and a stunning blonde walked into the room. She seemed confused when she saw us, begged our pardon, and said she was looking for her cousin, Danny Griswold. She had entered the wrong room by accident. Harry offered to show her to Danny's rooms, but she said she could find the way. Still she was in no hurry to go, and I began to be rather nervous, for I did not fancy the idea of having a young lady without a chaperon visit us. I feared it would become known, and we would receive a reprimand. She was decidedly giddy, and she sat on the arm of the easy-chair there and giggled and said it must be so nice to be a boy and go to Yale. After a while I began to smell a rat. I got up and took a closer look at her. Say, she was gotten up in great shape! It was that little imp Griswold!" "Well, what is your scheme?" asked Jack, smiling. "It is to put Griswold onto Thornton. Let Danny rig up and see what he can do. It's ten to one Thornton will think he has a new mash, and then we can have any amount of sport with the fellow." Jack looked more doubtful than ever. "I don't see how that is getting square with him," he declared. "If the game works, you can pretend to be in love with the same girl. You can challenge Thornton to mortal combat. He won't dare meet you. Then you can expose him, and if that will not be getting even with him I don't know how you can get even." This scheme did not exactly meet Diamond's approval, and Frank found it difficult to induce him to agree to it. At last, however, Merriwell succeeded. "We'll have barrels of fun out of this," laughed Frank. "I feel in need of a little fun to wake me up." CHAPTER XV. THORNTON'S "MASH." Tom Thornton was alone in his room when there came a knock on the door. "Come in," called Tom, without turning his head or taking his feet down from the table on which they were resting. As he had been out late the night before, he was not in a very agreeable mood. He had sent for his tailor some time before, and he supposed it was the tailor who had knocked and entered at his command.
