"Nope," was the laconic reply. "I'll find out. It's a mighty good bunch of stuff. Lots of three-year steers, an' thar ain't many three-year-olds left in these parts, now."

"It's worth looking up," commented Traynor. "I'm glad you spoke of it. How soon will you be ready to hit the trail?"

"'Bout ten minutes."

"Keep the boys out of mischief this trip, if you can."

There was a twinkle in Traynor's eyes that was reflected in the grey ones of the cowboy, who said soberly, "I'll do my best. But when they get to mixin' in things they're slipperier than a bunch of quicksilver. You think you got hold of it and you find you ain't."

Limber turned his pony toward the corrals, twisting in his saddle as Traynor called after him, "Tell some one to saddle my pony and Doctor Powell's. We'll ride out with you."

As the cowboy disappeared, Traynor said, "It will give you a faint idea of the work. You'll find it mighty different from the cowpuncher's life of moving pictures."

The doctor laughed. "I feel like a small boy about to wriggle under the canvas of a circus tent. I never dreamed that Arizona was such a wonderland."

The eyes of the two men swept across the Sulphur Spring Valley that undulated twenty miles from the Galiuro Mountains on the west to the Grahams on the east; starting sixty miles north of the Diamond H in the narrow Aravaipa Cañon, it gradually broadened into a great plain that terminated at the Mexican border.

"Of course," continued the doctor, "I had a vague idea of its mineral wealth and cattle interests, but I must confess that until I reached here the name of Arizona conjured visions of burning desert, Gila monsters, rattlesnakes, horn-toads and Apaches. Even when I stepped from the train and met you, the impression of a 'No-Man's Land' was strong upon me. Yet now that I have been here a month I feel as though I shall never want to leave it."
