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 Canon, 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." "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.
