"I haven't thrown any books, Mr. Haskers," answered Dave, calmly.

"What!"

"I threw that book, Mr. Haskers," said Roger, promptly. "But I didn't throw it at you."

"Ahem! So it was you, Master Morr! Nice proceedings, I must say. Instead of going to bed you all cut up like wild Indians. This must be stopped. Every student in this room will report to me to-morrow after school. I will take down your names." The teacher drew out a notebook and began to write rapidly. "Who knocked over that stand?"

"I did," answered Shadow. "It was an—er—an accident."

"Who was making that awful noise dancing?"

"I was dancing," answered Sam. "But I don't think I made much noise."

"It is outrageous, this noise up here, and it must be stopped once and for all. Now go to bed, all of you, and not another sound, remember!" And with this warning, Job Haskers withdrew from the room, closing the door sharply after him.

"Now we are in a mess!" muttered Roger.

"Isn't it—er—dreadful!" lisped Polly Vane, who had taken no part in the proceedings, but had been looking over Dave's book on polar explorations.
