"Oh, what a mean man!" exclaimed Grace Knox.

"Isn't it a shame!" echoed Gertrude.

"I'm so sorry on account of you boys," spoke Mrs. Morton. "It was fine of you to come to offer help, but you never thought of being caught, I dare say."

"Oh, yes we did," spoke Frank. "We always take that chance when we run the guard. But it doesn't matter."

"What will he do to you?" Mrs. Morton wanted to know.

"Oh, make us do a lot of lines in Latin prose," answered Andy.

"Then you won't be expelled?" asked Grace.

"No danger of that," laughed Frank. "They need all the students they can get at Riverview. But I wouldn't like dad and mother to hear that we were reported, especially when it isn't for anything very wrong."

"If you could only get back to the school before he does, you might be in your rooms, and he would hardly know whether he saw you here or not," said Miss Gertrude with a mischievous smile.

"But they can't," said her mother. "Mr. Callum will catch the next trolley, and there isn't another for an hour."
