But Frank, who knew the sly cow puncher so well, believed that more or less of his indifference was assumed.

"Well, I do!" declared Peg, with emphasis; "and if I'd only known about that sort of thing before, blessed if I'd a come. I've heard what happens when the side of a mountain tears away, and how everything in the path goes along. They showed me the bare wall where one broke loose up in Colorado. Say, it was the worst sight ever. You'll have to excuse me from nosing around here another day, if that sort of thing is hanging over this place. Me for the ranch on the jump. Get that, Nick?"

"Oh! now, what's the use botherin'? Chances are three to one they ain't agoin' to be any sech upsets as that yet awhile," the cowboy said.

"Only three to one!" burst out Peg. "All right, you can stick it out if you want, and I'll pay you all I agreed; but just you understand, Nick Jennings, when to-morrow comes, I want you to get me down on the prairie, where I can make a blue streak for the X-bar-X ranch house."

"But ye sed as how ye was detarmined to find out what made them roarin' n'ises, up here on old Thunder Mountain!" protested the guide, although he evidently expressed himself in this way only to further arouse the obstinate boy.

"I've changed my plans, that's all," Peg announced. "Any fellow can do that. It's always the privilege of a gentleman to alter his mind. I'd like to crow over Frank Haywood and that greenhorn chum of his mighty well; but I ain't going to run the chance of being carried down in a landslip just for that. Huh! I guess not! What I said, stands, Nick. And I hope the old slide comes while those two chaps are on the mountain; yes, and gives them a dandy free ride, to boot!"

"Oh! jest as ye say, Peg! I'm willin' to do anythin' to please ye. But p'raps we ain't goin' to git off so easy arter all," remarked Nick, suggestively.

"Now, what do you mean by hinting in that way? And I've noticed you twisting your neck to look up at the sky more'n a few times. Think it's going to rain, do you?" demanded Peg.

"Don't think nawthin' 'bout it; I know it be." And, Nick added, with emphasis, "I reckons as how it'll be jest a screamer when she comes."

"A storm, you mean?"
