"I am Miss Gertrude Morton, of Dailsburg," said the girl as she shook hands with the boys. "I can't thank you enough for what you did. I don't suppose he meant any real harm, but he frightened me."
"The brute!" murmured Frank, clenching his fists as he looked at Miss Gertrude's pretty face.
"Do you boys live around here?" she asked, after a pause. "I live just a few miles up the river, not far from Riverview Hall."
"Is that so?" exclaimed Frank—very eagerly Andy thought. "We are going to school there. We're on our way now."
The girl looked very much surprised.
"By the way, who was that man who spoke so harshly?" asked Andy.
"Why, don't you know him?" inquired Miss Morton. "If you—but you say you are just going to Riverview Hall. Then you will soon make his acquaintance, for he is Professor Thorndyke Callum, the head assistant at Riverview."
For a moment amazement held Frank and Andy dumb. Then the older lad exclaimed:
"Great Scott! Head assistant at Riverview! What are we up against? He'll have it in for us after what we did."
The girl looked half alarmed and half amused as she bowed to the boys and left the cabin. Andy and Frank stood staring at one another.
