He paused long enough, to jerk out a sack of tobacco and cigarette papers, letting the reins fall on his pony's neck as he glared at the cow. She was slowly dropping to the rear of the herd, but Bronco and his pony did not relax their vigilance.

"Mebbe you thought I didn't know you, you old buckskin bag o' bones," apostrophized Bronco. "I'd know that derned twisted horn if I was dead twenty years!"

Holy Dick galloped up, grinning broadly.

"Hello, Bronc! Ain't that your ol' buckskin friend?"

Bronco snorted. "Yep! An' you bet she's goin' to keep movin' until she's loaded in the car and headed for trouble somewhar else. Arizona ain't big enough to hold her an' me."

Holy rode off, turning in his saddle and screaming in a shrill nasal whine that he fondly imagined was singing:

"'Tis ye-a-a-rs since las-s-s-st we-e-ee met
An' we ma-a-aa-ay not me-ee-et agin.
I stru-ug-gle to-o-oo forgit
But I stru-ug-g-g-gg-g-ll-l-ll-le aa-aal in va-aa a-in."

Holy's pony contributed to the tremolo effect by its short, nervous trot.

"I'm glad she's a gittin' offen the range," soliloquized Bronco, "but I'll always be sorry we didn't butcher her on the ranch so's I could help chaw her up. If ever I get to Heaven all I'll ask is to eat buckskin cows for everlastin'."

As he uttered the last words Bronco raced ahead, leaving Doctor Powell at liberty to laugh and wonder what the mystery of the buckskin hoodoo might be. Then his eyes wandered from the dust-cloud ahead of him to the purple-blue peaks that reached thousands of feet upward as if striving to pierce the brilliant sky; across the valley clumps of greyish brown saccaton grass, slender tufts of waving gietta interspersed by tall spikes of Spanish Dagger formed a typical Arizona landscape.
