“I know them!” shouted Jack. “They must be Pornell students. Roy Bock, I know your voice.”

“I am not Roy Bock,” was the answer, in a disguised voice.

“You are. What are you going to do with us?”

“We are going to give you a lesson,” growled Roy Bock, for it was really he who had spoken. “Come down out of that buggy!”

As Bock spoke one of the boys leaped forward and secured the whip and two others pulled away the reins. There was no help for it, and Jack, Pepper, and Andy had to leap out. They were at once surrounded.

“This is a pretty high-handed proceeding,” said Jack, in a steady voice. “Don’t you know we can put you in the hands of the law for it?”

“Bah!” growled one of the masked students. “You don’t know us.”

“Perhaps we do.”

“We know Bock, and Grimes, and Gussie,” put in Pepper.

“None of them here,” said one of the Pornell boys. “You are on to the wrong crowd entirely.”
