"What is it?" suddenly whispered Rude.
The plainsman lay in strained posture, his ear against the ground.
"Hide the wagon and horses in the clump of cottonwoods," he ordered, tersely. Springing to his feet, he ran to the top of the knoll above the hollow, where he again placed his ear to the ground.
Jones's practiced ear had detected the quavering rumble of far-away, thundering hoofs. He searched the wide waste of plain with his powerful glass. To the southwest, miles distant, a cloud of dust mushroomed skyward. "Not buffalo," he muttered, "maybe wild horses." He watched and waited. The yellow cloud rolled forward, enlarging, spreading out, and drove before it a darkly indistinct, moving mass. As soon as he had one good look at this he ran back to his comrades.
"Stampede! Wild horses! Indians! Look to your rifles and hide!"
Wordless and pale, the men examined their Sharps, and made ready to follow Jones. He slipped into the thorny brake and, flat on his stomach, wormed his way like a snake far into the thickly interlaced web of branches. Rude and Adams crawled after him. Words were superfluous. Quiet, breathless, with beating hearts, the hunters pressed close to the dry grass. A long, low, steady rumble filled the air, and increased in volume till it became a roar. Moments, endless moments, passed. The roar filled out like a flood slowly released from its confines to sweep down with the sound of doom. The ground began to tremble and quake: the light faded; the smell of dust pervaded the thicket, then a continuous streaming roar, deafening as persistent roll of thunder, pervaded the hiding place. The stampeding horses had split round the hollow. The roar lessened. Swiftly as a departing snow-squall rushing on through the pines, the thunderous thud and tramp of hoofs died away.
The trained horses hidden in the cottonwoods never stirred. "Lie low! lie low!" breathed the plainsman to his companions.
Throb of hoofs again became audible, not loud and madly pounding as those that had passed, but low, muffled, rhythmic. Jones's sharp eye, through a peephole in the thicket, saw a cream-colored mustang bob over the knoll, carrying an Indian. Another and another, then a swiftly following, close-packed throng appeared. Bright red feathers and white gleamed; weapons glinted; gaunt, bronzed savage leaned forward on racy, slender mustangs.
The plainsman shrank closer to the ground. "Apache!" he exclaimed to himself, and gripped his rifle. The band galloped down to the hollow, and slowing up, piled single file over the bank. The leader, a short, squat chief, plunged into the brake not twenty yards from the hidden men. Jones recognized the cream mustang; he knew the somber, sinister, broad face. It belonged to the Red Chief of the Apaches.
"Geronimo!" murmured the plainsman through his teeth.
