Before the echoes of the shot had died away a mad, inarticulate roar came from the depths of the wagon box. The roar was followed by a thick stream of oaths in an unmistakably Irish voice. The driver, who was slipping a fresh cartridge into the cylinder, looked up to see a man grasping the back of the rear seat for support while rising unsteadily to his feet. The Irishman, as he stood glaring fiercely at the man who had so rudely awakened him, was without hat or coat, and with bits of hay clinging to a soiled shirt that was unbuttoned at the hairy throat, presented a remarkable figure. His heavy body was fitted with legs like posts; his wide shoulders and deep chest, with arms to match his legs, were so huge as to appear almost grotesque; his round head, with its tumbled thatch of sandy hair, was set on a thick bull-neck; while all over the big bones of him the hard muscles lay in visible knots and bunches. The unsteady poise, the red, unshaven, sweating face, and the angry, blood-shot eyes, revealed the reason for his sleep under such uncomfortable circumstances. The silent driver gazed at his fearsome passenger with calm eyes that seemed to hold in their dark depths the mystery of many a still night under the still stars. In a voice that rumbled up from his hairy chest--a husky, menacing growl--the Irishman demanded: "Fwhat the hell do ye mane, dishturbin' the peace wid yer clamor? For less than a sup av wather I'd go over to ye wid me two hands." Calmly the other dropped his gun into its holster. Pointing to the canteen that hung over the side of the wagon fastened by its canvas strap to the seat spring, he drawled softly: "There's the water. Help yourself, stranger." The gladiator, without a word, reached for the canteen and with huge, hairy paws lifted it to his lips. After a draught of prodigious length he heaved a long sigh and wiped his mouth with the back of his hand. Then he turned his fierce eyes again on the driver as if to inquire what manner of person he might be who had so unceremoniously challenged his threat. The Irishman saw a man, tall and spare, but of a stringy, tough and supple leanness that gave him the look of being fashioned by the out-of-doors. He, too, was coatless but wore a vest unbuttoned over a loose, coarse shirt. A red bandana was knotted easily about his throat. With his wide, high-crowned hat, rough trousers tucked in long boots, laced-leather wrist guards and the loosely buckled cartridge belt with its long forty-five, his very dress expressed the easy freedom of the wild lands, while the dark, thin face, accented by jet black hair and a long, straight mustache, had the look of the wide, sun-burned plains.
