"All of those Rovers up here, and armed!" came from Nappy.
"Who gave you the right to come to this island?" went on the bully, glaring at Jack.
"Do you know these boys?" queried the man who was with Professor Lemm.
"Sure, Dad, I know them! They are the Rover boys I told you about—the fellows who helped to have me and Nappy sent away from school."
"Oh, so that's it!" cried Slogwell Brown. "Did you have any idea they might be up here?" he questioned quickly.
"Not the least, Dad. I thought they were down in New York. Nappy said he had seen them on the ice in Central Park."
"I did see them, too," answered the lad mentioned.
"Well, we didn't come here to see you Rovers," broke in Asa Lemm stiffly. "Not but what I have an account to settle with you," he continued significantly.
"We want nothing more to do with you, Professor Lemm," answered Jack boldly.
"But I'm going to have something to do with you, young man!" stormed the former teacher of the Hall, beginning to show his usual ill humor.
