“I’ve got an idee, sir. I might get a ladder and put it up to the second-story winders.”

“Yes, yes. Get the ladder at once.”

The general utility man hurried off to the carriage house and presently came forth carrying a long ladder.

“It’s all I can do to lift it, sir,” he said. “You’ll have to help me raise it.”

“I can do that.”

“They’ve got a ladder!” whispered Jack. “They are going to try to get into one of the upper windows.”

“Come on upstairs,” returned Pepper. “Say, has anybody got a blank cartridge left?”

Several had, having saved them from the encampment, and they were passed over to Pepper, who placed one in his gun. Then Andy loaded up likewise.

“Put on your caps, boys,” said Pepper. “Pull ’em down over your eyes, so Crabtree can’t recognize us in the dark.”

This was also done, and a score of students crowded into the room which the teacher and Snuggers expected to enter.
