"Let 'em laugh. Our turn will come sooner or later."
Frank joined his chums that afternoon, when school had closed for the day, and all went swimming. There was quite a crowd of pupils at the river, including a number of the Upside Down boys, and there were several rather warm discussions among the members of the rival factions. Once or twice it looked as if there might be fights. Lem Gordon, in particular, was much incensed at the action of the first-years, and when Richard Kirk, a member of the Upside Down Club, taunted Lem with belonging to the side that lost in the Saturday night struggle, Lem advanced toward Richard and acted as though he was going to strike him.
"Don't," advised Bart. "That will only make them keep the thing up longer. We'll fix 'em."
"We ought to do it pretty soon," growled Lem. "I'm getting tired of being laughed at. We ought to pay back the ringleaders anyhow. Who were the fellows that held you, Frank?"
"It was so dark I couldn't see well."
"You ought to have recognized some of 'em."
"I didn't," Frank answered, somewhat shortly, as he began to dress.
"What makes Frank act so queerly?" inquired Lem of Bart. "Has anything happened?"
"Not that I know of," Bart replied carelessly. He did not want other pupils to think Frank strange, even if the three chums did. When Frank had finished dressing he started away.
"Where you going?" Fenn called after him.
