“That outbids my pile!” the range-rider exclaimed. “Which I’ve always been able to hand out a pony’s age by lookin’ at his teeth, but when it comes to followin’ a trail a million years old, why, I can’t sit in for that game. But as long as you like to talk I’ll keep my ears right up, listenin’!”

“Smooth as a card-sharp with a stacked deck,” declared the range-rider. “Which if you’re ridin’ back, gents, that’s my trail, too,” and without further word, he wheeled his pony and started up the gully.
