“Then perhaps I can get this plan to work after all,” went on The Imp, and then he told the others of his scheme. This was nothing more than to send a letter to Bock asking him and his cronies to meet Ritter at a certain ice-house on the lake front, at two o’clock—just an hour before the party was to come off. Another letter was to be sent to Ritter asking him to meet Bock and his crowd at the same place, but a little earlier.

The letters were written without delay and a farm boy of that vicinity was hired to deliver them both at noon on the day the party was to come off. Each letter spoke of “a way to fix Ruddy and his crowd,” and was unsigned.

As Pepper anticipated, Bock and Ritter and their cohorts fell into the trap readily. Each bully was more than anxious to learn of something whereby he might do the young major and his chums injury.

“Ritter is a fine fellow,” said Roy Bock, to his cronies. “He hates Ruddy and those other chaps like poison, too. He must have something great up his sleeve.” And the others agreed this must be so; and all voted to stop at the ice-house on the way to the lawn party.

On the other hand, Ritter was equally enthusiastic, and so were Coulter and Paxton.

“We’ll work with the Pornell fellows in this,” said the Hall bully. “I always liked Bock, and if he will show us how to turn a trick on Ruddy I’ll like him better than ever.”

It was no easy matter for Jack, Pepper and the others to get away early on the day the lawn party was to be held. Yet they managed it by various excuses, and then met back of the gymnasium, and hurried at top speed to the ice house.

The structure was empty, the last of the former winter’s ice having been removed the week before. It was a large and gloomy place, and scattered around were many tons of wet sawdust.

“Now boys, follow my directions and be quick about it!” cried Pepper. “Andy, you keep an eye open and let us know as soon as you see anybody. Jack, here’s your make-up,” and as he finished speaking he handed over a suit of plain clothes and a hat, such as Bock was in the habit of wearing. These the young major donned with all speed, and pulled down his hair over his forehead, in the style Bock affected. This done, at a distance he resembled the bully of Pornell Academy.

The cadets set to work doing various things in the ice house that Pepper suggested. Hardly had they completed their labors when Andy gave a low whistle.
