"What I am thinking of is, what made them suspicious, after they were so far from Casey's Forks," said Allen.

"Perhaps their guilty consciences," laughed Noel.

"Thet, an' because they thought I might be follerin' 'em," added Ike Watson. "Hullo! What does this mean?"

He had followed the trail around a belt of timber. Beyond was a wall of rocks, and here were traces of a recent camp—a smoldering fire and some odds and ends of crackers and meat.

"We ain't far behind 'em, boys!" he went on. "This fire wuz tended ter less than a couple o' hours ago."

"Then let us push on, by all means," returned Allen. "If we can catch those two men before they have a chance to join any of their evil companions, so much the better."

"The trail leads along the rocks," observed Noel. "Have you any idea where we are going?"

"Idee! I know this yere country like a book," said Ike Watson. "Don't ye git 'feered o' bein' lost so long ez ye stay nigh me."

"I don't mean that. I mean, do you know where the men went from here?"

"Up to Grizzly Pass, most likely, an' then along over ter the Black Rock Canyon. Eh, Allen?"
