Suddenly Pronto shied violently, tried to bolt up the cliff, scrambling goatwise for twenty feet to stand shivering and snorting. Sandy's balance was automatic, the muscles of his knees clamped for grip, he gave the pinto its head, trusting to it to establish footing. He saw Sam's roan dancing in the trail, the led mare plunging, dust rising all about them. Left-handed, a Colt flashed out of Sandy's holster, barked twice, the echoes tossing between the canyon walls. In the road a rattlesnake writhed, headless, its body, thicker than a man's wrist, checkered in dirty gray and chocolate diamonds. "Git down there, you hysteric son of a gun," he said to the horse. "It's all over." The pinto hesitated, shifted unwilling hoofs, squatted on its haunches and, tail sweeping the dirt, tobogganed down to the road, jumping catwise the moment it was reached, away from the squirming terror. Sandy forced him back, leaned far down, tucked the barrel of the gun under the snake's body and hurled it looping into the gorge. Sam got his roan and the mare under control as the dust subsided. "More'n a dozen buttons," said Sandy. "Listen!" Grit, unseen, ahead, was barking in staccato volleys. There was another sound, a faint shout, unmistakably; human. The men looked at each other with eyebrows raised. "That ain't no man's voice," said Sam. "That's a gal." He looked quizzically at Sandy, knowing his chum's inhibition. Sandy was woman-shy. Men met his level glance, fairly, with swift certainty that here stood a man, four-square; or shiftily, according to their ease of conscience, knowing his breed. Sandy was a two-gun man but he was not a killer. There were no notches on the handles of his Colts. In earlier days he had shot with deadly aim and purpose, but never save in self-defense and upon the side of law and right and order. Among men his poise was secure but, in a woman's presence, Sandy Bourke's tongue was tied save in emergency, his wits tangled. Whatever he privately felt of the attraction of the opposite sex, the proximity of a girl produced an embarrassment he hated but could not help. He had seen admiration, desire for closer acquaintance, in many a fair face but such invitation affected him as the sight of a circling loop affects a horse in a remuda. He gave Sam no chance for banter. Action was forward and it always straightened out the short-circuitings of Sandy's mental reflexes toward womankind. He touched Pronto's flanks with the dulled rowels he wore, and the pinto broke into a lope. A big boulder was perched upon the nigh side of the road. Grit came out from behind it, barked, whirled and seemingly dived into the canyon. Coming up with the mare, Sam found Sandy dismounted, waiting for him.
