Prince, a gray, short-haired dog, of intricate ancestry, squatted on his haunches in the snow with his tongue between his teeth and his eyes on the two horses. Swift sagged with a sigh onto three legs. Perhaps the little mare deserved some of the aspersions Douglas and his father daily cast upon her. She was a half-broken, half-fed little mare which Douglas' father had cast off. She did not look strong enough to bear even Judith's slim weight. But as the only horse Judith was permitted to call her own, the little bay was the very apple of the young girl's eyes, and she wheedled wonderful performances from Swift in endurance and cat-like quickness. Buster was a black which the older Spencer had bred as a cow-pony but had given up because he could not be broken of bucking. Doug had begged his father for the horse, and Buster, nervous, irritable and speedy, was a joy to the boy's sixteen-year-old heart. Douglas sat tall in the saddle. He measured, in fact, a full five feet ten inches without his high-heeled riding-boots. He was so thin that his leather rider's coat bellowed in the wind, and the modeling of his cheekbones showed markedly under his tanned skin. His sombrero, pushed back from his forehead, disclosed a thick thatch of bright yellow hair above wide blue eyes that were set deep and far apart. His nose was high bridged, and his mouth, though still immature, gave promise of full-lipped strength in its curves. Judith was fourteen and only a couple of inches shorter than Douglas. She was even thinner than he, but, like him, glowing with intense vitality. She had hung her cap on the pommel of her saddle and her curly black hair whipped across her face. She had a short nose, a large mouth, magnificent gray eyes and cheeks of flawless carmine. She wore a faded plaid mackinaw, and arctics half-way up her long, thin legs. "I hate you, Doug Spencer," she said finally and fiercely, "and I'm glad you're not my real brother!" "I don't see why my father ever married a woman with an ornery brat like you!" retorted Douglas. "I wouldn't stay to associate with you another minute if you offered me a new pair of spurs! I'm going to meet Maud!" And Judith disappeared down the trail. Douglas eased back in his saddle and lighted a cigarette, while he watched the distant figures approaching across the valley. The glory of the landscape made little impression on him. He had been born in Lost Chief and he saw only snow and his schoolmates racing over the converging trails. The Rockies in mid-winter! High northern cattle country with purple sage deep blanketed in snow, with rarefied air below the zero mark, with sky the purest, most crystalline deep sapphire, and Lost Chief Valley, high perched in the ranges, silently awaiting the return of spring.
