They did this, making the entire round of the school building. Every door was shut and locked, even that to the kitchen addition being tight.

"Now we are in a pickle and no mistake," groaned the senator's son.

"I suppose the other fellows have gotten tired of waiting for us and gone to bed," said Shadow. "We've been away an hour and a half longer than we expected."

"One thing is certain, we must get into the Hall somehow," said Dave. "We can't stay out here all night."

"Let us go around under one of our windows," said Roger.

They were soon under a window of Dormitory No. 12. It was open from the top to admit the fresh air. All was dark in the school building and they had only the starlight to guide them.

Gathering up a handful of pebbles, Dave threw them at the window and Roger and Shadow followed suit. At first nobody paid attention to this. Then the window was raised from the bottom and the head of Phil appeared.

"Hello you!" he called softly. "Thought you were going to make a night of it."

"We were delayed," answered Dave. "All the doors are locked. Can't you open one for us?"

"I'll see."
