discovered.”

“Let us send the cakes up by way of the window,” suggested Henry. “It won’t do to be caught with them in our possession—if Coulter and Ritter have squealed.”

The boys ran across the campus, stooping at the roadway to pick up some pebbles. These they threw up to the window of one of the dormitories. It was a well-known signal, and the sash was immediately raised and Jack’s head appeared, followed by the head of Dale.

“What’s wrong?”

“Lower a line and haul up these two boxes,” answered Henry.

“Coulter and Ritter are onto our game,” said Pepper. “Mumps gave us away.”

No more was said just then. A strong fishing line was let down from above, and one pasteboard box after another was raised up. Then the two cadets on the campus ran around to the side door of the Hall.

“As I suspected, they locked it,” said Pepper, rather bitterly.

“Well, we’ve got to get in somehow. Wonder if they can’t let down a rope of some kind?”

“They might let down the rope in the bath-room,” answered Pepper. He referred to a rope which was tied to a ring in the bath-room floor. This had been placed there in case of fire, even though the school was provided with regular fire escapes.

Once more they summoned Jack and the others, and Jack ran to the bath-room and let the rope down. Then those below came up hand over hand, bracing their feet against the wall of the building as they did so.

As the boys came from the bath-room they heard light footsteps on the back stairs. Andy and Dale were coming up, each with a big pitcher of lemonade. Both were snickering.

“Where does the fun come in?” asked Jack, as all hurried to his dormitory.

“A joke on Coulter and Ritter,” cried Andy, merrily. “We caught them nosing around downstairs and I called them into the store-room in the dark. Then I slipped past them and locked them in. They can’t get out excepting by the window, and then they’ll have to get back into the Hall.”

“It serves ’em right,” answered Pepper, and then told of what had been heard by himself and Henry down by the apple-tree. “We ought to pay Mumps back for spying on us, too,” he added.

It was voted to dispose of the strawberry shortcake and the lemonade at once. The cakes were cut up and passed around, and voted “the best ever.” The lemonade was also good, and the cadets drank their fill of it.

“What are you going to do with the two pitchers?” asked Joe Nelson.

“Sure an’ I have an idea, so I have,” came from Emerald. “Phy not leave ’em in Mumps’s room?”

“That’s the talk,” cried Pepper. “And we’ll leave this chunk of ice, too,” and he rattled the piece in the pitcher as he spoke.

Taking the two pitchers, the Irish student and Pepper approached the dormitory in which John Fenwick slept, along with Ritter, Coulter, Nick Paxton and Dan Baxter. They found the door unlocked and pushed it open. To their astonishment they met Mumps face to face. He was waiting for the return of Ritter and Coulter.

“Say, what do you want?” he began, but got no further, for without ceremony both boys thrust the empty pitchers into his arms. Then Pepper rammed the piece of ice down Mumps’s neck, and he and Emerald ran off swiftly and silently.
