"Oh, these kids think they can go where they like," said the man with the gun. "I've warned 'em away, but they won't go."

"They won't; eh?" snapped the newcomer, who bestrode a big black horse. "Well, I'll see about that."

"Oh, we're going, Rick Morton," said Billy, calmly. "We just rode out here to see what was going on, and now we're going back. I'll tell my uncle."

"Yes, and you can tell him if he comes out here I'll serve him as he once served me!" snapped the big man.

"Oh, I suppose you mean horsewhipping," spoke Billy. "Well, I wouldn't advise you to try it!"

"Now you march!" fairly yelled the big man, to whom the remembrance of the horsewhipping did not seem pleasant.

"Come on, Buffalo," called Billy, to his horse. "I guess they don't want us here."

"And we never will," added the man with the gun. "You can't dam up this river, and flood our property. The courts'll stop you, or, if they don't, we will ourselves. This dam will be torn down in another month."

"I don't believe so," answered Billy. "Come on, boys," and he motioned with his head to Frank and Andy.

"Can't we do anything?" asked the younger Racer lad, who did not like to thus easily give in.
