A man might have had some trouble in keeping to the trail, but Jack trotted easily along and never once seemed at fault.

In a very few minutes he stopped in a rocky depression where a horse had been tied, and waited for Swan, wagging his tail and showing his teeth in a panting smile.

The man he had trailed had mounted and ridden toward the ridge to the west.

Swan examined the tracks, and Lone sat on his horse watching him.
Jack picked up the trail where the horseman had walked away toward the road, and Swan followed him, motioning Lone to ride ahead.
"You could tell me about this, I think, but I can find out for myself," he observed, glancing at Lone briefly.
"Sure, you can find out, if you use your eyes and do a little thinking," Lone replied.

"I hope you do lay the evidence on the right doorstep." "I will," Swan promised, looking ahead to where Jack was nosing his way through the sagebrush.
They brought up at the edge of the road nearly a quarter of a mile nearer Echo than the place where Frank's body had been found.
