His pony started under him, gave a sharp little shudder, then moved a step backward and stood still, a barely perceptible tremor shaking his limbs.
Then a sound new and strange came to Danny. He did not know its origin, but it contained a quality that sent a thrill pulsing from his heart. Shrill it was, but not sharply cut, wavering but not breaking; alarm, warning, concern, caution—the whistle of a stallion! Then silence, while the mares stood rigid and the saddle horse held his breath.
Again it came, and a quick chill struck down Danny's spine. His searching eyes encountered the source. There, halfway between the mares and the crown of the ridge he stood, out on a little rim-rock that made a fitting pedestal, alert, defiant, feet firmly planted, with the poise of a proud monarch.
Even across the distance his coat showed the glossiness seen only on fine, short hair; his chest, turned halfway toward the rider, was splendid in breadth and depth, indicating superb strength, endurance, high courage. Danny looked with a surge of appreciation at the arch of the neck, regal in its slim strength, at the fine, straight limbs, clean as a dancing girl's; at the long, lithe barrel with its fine symmetry.
A wandering breath of breeze came up the gulch, fluttering the wealth of tail, lifting the heavy mane and forelock. The horse raised a front foot and smote the ledge on which he stood as though wrath rose that a mere man should ride into his presence, and he would demand departure or homage from Danny Lenox. He shook his noble head impatiently, to clear his eyes of the hair that blew about them. And once more came the whistle.
The mares stirred. One, a bright buckskin, trotted up the rise a dozen yards, and stopped to turn and look. The others moved slowly, eyes and ears for Danny.
Again the whistle; a clatter of loosened stones as the black leader bounded up the hillside; and the bunch was away in his wake.
"The Captain!" Danny breathed, and then, in a cry which echoed down the gulch—"The Captain!"
He was scarcely conscious of his movements, but his quirt fell, his spurs raked the sides of his pony, and the sturdy little animal, young and not yet fully developed, doing his best in making up the ridge, labored effectively, perhaps drawn on by that same raw desire which went straight to the roots of Danny's spirit and came back to set the fires glowing in his eyes.
The boy rode far forward in his saddle, his gaze on the plunging band that scattered stones and dirt as they strove for the top. But he was many lengths behind when the last mare disappeared over the rim. He fanned his pony again, and the beast grunted in his struggles for increased speed in the climbing, lunging forward with mighty efforts which netted so little ground.
