“Yas, I see him. Long way off, but I see him.”

“Did you know him?”

“Yas, I know him.”

“Who was it?” Ralston was in the saddle now.

“Little white man—what you call him ‘bug-hunter’—at de MacDonald ranch.”

“McArthur!” Their horses were gathering speed as they turned them toward the Bad Lands.

“Yas. Little; hair on face—so; wear what you call dem sawed-off pants.”

From the description, Ralston recognized McArthur’s English riding-breeches, which had added zest to life for the bunk-house crowd when he had appeared in them. The deputy-sheriff was bewildered. It seemed incredible, yet there, still in sight, was the flying band of horses, and Bear Chief’s positiveness seemed to leave no room for doubt.

“Oh, him one heap good thief,” panted Bear Chief, in unwilling admiration, as their horses ran side by side. “He work fast. No ’fraid. Cut ’em out—head ’em off—turn ’em—ride through big brush—jump de gulch—yell and swing de quirt, and do him all ’lone! Dat no easy work—cut out horses all ’lone. Him heap good horse-thief!”

What did it mean, anyhow? Ralston asked himself the question again and again. Was it possible that he had been deceived in McArthur? That, after all, he was a criminal of an extraordinary type? He found no answer to his questions, but both he and Bear Chief soon realized that they were exhausting their horses in a useless pursuit. It was growing dark; the thief had too much start, and, with the experience of an old hand, he drove the horses over rocks, where they left no blabbing tracks behind. Once well into the Bad Lands, he was as effectually lost as if the earth had opened and swallowed him.
