"Absolutely," added another student, who had seen the whole affair.

"Well, Porter, you had better come to the doctor's office and we'll investigate further," said the teacher, and a little later Dave found himself confronting the master of Oak Hall. He told his story in a straightforward manner and mentioned the names of several who had witnessed the affair. Then he was told he could go, and Frank was called in, and then Ben, Shadow, Buster, and later still Plum and Poole. The doctor questioned all closely, and finally sent Andrew Dale after Jasniff, but the youth could not be found.

"Has he left the school grounds?" questioned Dr. Clay.

"I could not find that out," answered the assistant. "Nobody seems to have seen him since he left the gymnasium."

"Well, as soon as he shows himself, send him to me."

"I will, sir."

"From what I can learn, he is a thoroughly bad boy," went on the master of Oak Hall, beginning to pace the floor of his office. "I must confess I hardly know what to do with him."

"He is a bad boy, no doubt of that," answered the teacher. "And he has a bad influence on some of the other boys."

"You mean Plum and Poole?"

"I do."
