"Hurrah! that's the way to do it, Jack!" cried Spouter.

"Say! has he got to fight two of you Rovers?" questioned Slugger Brown.

"No. He's got to fight me only," answered Jack, quickly. He turned to his cousin. "Fred, you keep out of this."

"But he started on me," pleaded the youngest Rover. "And now that you are here to see fair play, I'm not afraid of him."

"Never mind. It's my fight, anyway," went on Jack. "I owe him one for the way he treated me down in Wall Street that day."

While this talk was going on, Nappy Martell had scrambled to his feet. His nose was swollen and bleeding profusely.

"You imp!" he howled, and lunged another attack at Jack.

He was able to land two blows on Jack's chest, but they were not powerful enough to do harm. Then, as Martell circled around, the oldest Rover boy managed to get in another blow, this time on his opponent's mouth, loosening two of Nappy's teeth.

"That's the way to do it, Jack!"

"Give him a few more like that and he'll soon quit."
