Haskers reached his own room and threw open the door. He made a light, and gazed around in great perplexity. Everything was in perfect order excepting the bedclothes, which were just as he had left them. He walked slowly to the window and drew in the rope that was used for a fire escape.
"Strange! Strange!" he murmured to himself, as he scratched his head. "I was sure the bed moved. Can I have been dreaming after all? I ate a rather heavy supper, and my digestion is not as good as it used to be."
He put on his slippers and donned a dressing gown, and thus arrayed sallied forth once more, this time in the direction of the dormitory occupied by Dave and his chums. He approached on tiptoe and opened the door quickly and noiselessly.
But the students had had ample time in which to get to bed, and every one was under covers and apparently sleeping soundly. To make sure they were not shamming, the teacher came in and gazed at one after another closely. Then, with a face that was a study, he left the dormitory again and walked slowly to his own room.
"Is he gone?" asked a voice in the dormitory, after a full minute of silence.
"Yes, Phil," answered Dave. "But don't make any noise—he may come back."
