The sheriff's courage again failed him as he looked up into the direct, unwavering eagle gaze of the young officer. He began to curse. "We'll have your hide for this! You've gone too far! You've defied the laws of the county!" "Drive on," said Curtis, and Two Horns touched his ponies with the whip. "Halt, or I fire!" shouted Winters. "Drive on!" commanded Curtis, and Two Horns laid the whip hard on the back of his off horse. Winters fired, but the bullet went wide; he dared not aim to kill. Cut Finger rose as if to leap from the wagon, but Crow seized him with one great brown paw and thrust his shining gun against his breast. "Sit down, brother!" he said, grimly. "We'll care for you." The prisoner sank back into his seat trembling with excitement, while the wife began to cry piteously. Curtis, looking back, saw the sheriff waving his revolver maniacally, but his curses fainted on the way. A sudden reaction to humor set in, and the young agent laughed a hearty chuckle which made his faithful Tetong aids break into sympathetic grins. Nevertheless, the case was not entirely humorous. In a certain sense he had cut athwart the law in this last transaction, though in doing so he had prevented an act of violence which would have still further embittered the tribe. "I am right," he said, and put away all further doubt. The drive now settled into a race for the jail. "The sheriff, after being picked up by his own party, will undertake to overhaul us," reasoned Curtis, but that did not trouble him so much as the thought of what lay before him. The road ran along Willow Creek, winding as the stream itself, and Curtis could not avoid the thought of an ambuscade. On the right were clumps of tall willows capable of concealing horsemen, while on the left the hot, treeless banks rose a hundred feet above the wagon, and the loopings of the track prevented a view of what was coming. If the mob should get impatient, or if they should suspect his trick, it would be easy to send a detachment across the hills and intercept him. "Push hard!" he signed to Two Horns. The road was smooth and dusty and descended rapidly, so that the horses had little to do but guide the tongue. As the wagon rocked and reeled past the ranch houses, the settlers had hardly time to discern what manner of man was driving, but they were thrown into fierce panic by the clatter of fleeing horses and the cloud of prophetic dust. The sheriff was not in sight, and no sound of him could be detected in the whiz of their own wheels. At last Two Horns, with his moccasined foot on the brake, broke through the hills out upon the valley land, with Pinon City in sight. The mob and the sheriff were alike left behind. Ambush was now impossible. "Easy now, Two Horns," called Curtis, with a smile and an explanatory gesture. "We're safe now; the angry white men are behind," and the reeking, dusty, begrimed horses fell into a walk.
