"You can make sure of that," retorted Traynor, "if you will go to the Hasayampa River, kneel on the brink and drink of the water. You must be very careful, though, to kneel above the crossing. This will keep you from ever wishing to leave Arizona and you will receive the gift of absolute truthfulness; but, should you drink while kneeling below the crossing, truth and you will be divorced the balance of your life."

"Did you drink below the crossing or above?" challenged the doctor with an amused smile.

"There is only one case on record where a man acknowledged that he drank the water below the crossing. His name was Hasayampa Bill. He died a year ago. Hasayampa Bill was a victim of circumstances, not intention. He said that he was drinking above the crossing when he lost his balance and fell into the stream which carried him far below. Though Hasayampa swore solemnly that he kept his mouth shut—for the first time on record—his reputation was thoroughly established. A letter addressed to the 'Biggest Liar in Arizona' was accorded him by popular vote."

The doctor was about to reply, when the air was filled with ear-splitting whistles and staccato cries. Then the big gates of the corral swung open, and an avalanche of cattle tumbled madly through and headed in a wild rush down the road that led south toward Willcox—excited bellows and plaintive lowing of calves seeking their mothers, mingled with the voices of invisible men, completely obliterated by the clouds of alkali dust.

Traynor led the way into the stable where two saddled ponies twisted nervously. The men looked at each other and smiled as the doctor approached the pinto pony. Its eyes showed whites, its ears went back. It sheered nervously, but Powell gained the saddle and, with Traynor close beside him, they reached the moving herd.

Through the haze of dust a shadowy rider would loom momentarily, then disappear. Traynor rode on the outer edge of the herd. Doctor Powell became aware that Limber had materialized at his side, and forgot everything else in his admiration of the cowpuncher's unconscious grace as his lithe, swaying figure adjusted itself to each movement of the wiry, dancing pony.

"Head off that buckskin," shouted Limber, rising in his stirrups and waving his quirt at a cow that was making a wild dash for freedom.

Bronco's pony emerged from the haze and tore madly after the cow, reaching her side just as she made up her bovine mind that she had no intention of deserting. Her expression of injured innocence as she ambled quietly back roused Doctor Powell's mirth and Bronco's ire.

The cowpuncher reined his pony beside Powell's, muttering imprecations that finally ended in a verbal explosion.

"Durn her! Whenever you turn an old buckskin cow like that loose in the herd it's as bad as sickin' a mother-in-law on a happy family. She won't rest till she gets 'em millin' and stampedes everything in sight, and then she picks up her knittin' and looks innercent and says she never allowed to start nothin' noways! Gee! I wish I could strike a ranch where there warn't nothin' but steers. The minute you mix up with a female critter, cow or petticoats, you're roundin' up trouble for yourself and lots of others."
