Looker was bigger and heavier than Bob, and for a time held his own, but Bob had the memory of more than one wrong to avenge, and a gallant spirit that took no heed of blows received so long as he could punish his enemy.

For many minutes they fought back and forth, giving and taking in fierce fashion. Buck landed one or two heavy blows, but Bob only shook his head and bored in more fiercely than ever. He rained blows on the retreating bully, who was soon getting enough and more than enough. At length Bob saw an opening, and quick as a flash a fist shot up and caught Looker square under the jaw. The bully's head rocked back, his knees sagged under him, and he dropped limply to the ground. Panting, Bob stood over him, waiting for Looker to get to his feet again, but when after a few seconds the bully opened his eyes, there was no sign of fight left in them.

"Get up, you big blowhard!" panted Bob. "I'm not through with you yet."

But Buck Looker was through, abjectly and entirely through.

"Have a heart, Bob," he whined. "I don't want to fight any more.
My jaw feels as though it was broken."

"I hope it is!" said Bob. "You big bully! What do you mean by climbing up on my barn and trying to wreck my aerial?"

"I won't ever try to monkey with it again, honest I won't!" whined Buck.

"You'd better not," advised Bob grimly. "And when you see your friends, tell them I'll do the same to them that I've done to you if they come around here. They'd better keep off these premises unless they're looking for trouble."

"I'll tell them to keep hands off," promised Buck, nursing his injured jaw. "Will you promise not to hit me if I get up?"

"Yes, get up and get out of here," said Bob, disgustedly, and he turned his back contemptuously on the bully and started for the house. As he turned his back, Buck scrambled to his feet with a look of malignant hatred on his face and looked about him, apparently in search of some object he could use as a weapon. Fortunately there was nothing handy that he could use as such, and after stealthily shaking his fist at Bob he sneaked off toward town, one hand still holding his injured jaw.
