"Well, you are to retire to Robinson's room, which is exactly opposite this, and wait. I have two fellows outside to let me know when the enemy approaches and to take a hand in the game at the right time. When I whistle you are to make your way into this room if you have to break down the door. That's all."
The boys retired to Robinson's room, where they smoked and waited with great impatience.
Frank sat down and coolly went at his studies.
Nearly an hour passed, and then there was a sound of wheels outside. The sound stopped before the door.
A few moments later some one ascended the stairs and there came a knock on the door.
"Come in," called Frank.
The door opened, and Roll Ditson sauntered in, smoking the inevitable cigarette.
"Hello, Merry!" he cried, looking around. "All alone?"
"All alone, Ditson," yawned Frank. "It's beastly stupid but I am having a hard pull at my studies."
"Better come out with me and get a little air. It's stuffy here."
