This was done, and then the two boys went back for the cage of bats. The other students in the dormitory wanted to see the fun, and half a dozen went out into the hallway. In order that they might not be seen and recognized, the light was extinguished.

"I am going to loosen the bottom of the cage and then throw the whole thing on Haskers's bed," said Dave. "Stand ready, somebody, to lock the door."

"I'll do that," answered Phil.

With caution the door was opened for a little over a foot. Then Dave loosened the bottom of the cage and shook the bats up. As they fluttered around he threw cage and all directly on the teacher's bed. Then the door was quickly closed and locked and the key thrown down into the lower hallway.

For a moment there was silence. Then from Job Haskers's room there arose a frightful shriek.

"Help! Get away! What is this? Oh, my eye! Get away, I say! Oh! oh! Save me! I shall be killed! Get away!" And there followed a series of yells and thumps and the overturning of a chair and a table.

"He is enjoying himself—I don't think!" cried Roger, with a chuckle. "Oh, say, listen to that!"

"Back to the room, or we'll be discovered," warned Phil, and back they ran with all speed.

But the strange commotion had aroused the whole Hall, and dormitory doors were opened on all sides and students rushed out to see what was the matter. Then Dr. Clay appeared, garbed in a dressing gown. Andrew Dale, the first assistant teacher, ran up from below.
