Then a long, pealing whoop went up. The Sioux had discovered him, and with exultant shouts each warrior lashed his pony into the utmost speed.
For half an hour the furious chase continued. Vipan, glancing over his shoulder, became aware that his pursuers were slowly gaining on him. On—on. The forest belt would soon be reached, and meanwhile the dusking shadows were lengthening around.
He gained the first straggling patch of scrub. A few hundred yards and he would be within the welcome refuge, when his horse put a foot on the crusted surface of a mud-hole, turned a somersault, and his rider came whizzing to the earth.
Vipan arose. Throughout the horror of the shock his self-possession did not desert him, for he retained firm hold of the lariat rope. He was on his feet again, active as a cat, though stiff and bruised, but his steed stood shaking with alarm, using its right foreleg limpingly.
A yell of exultation went up from the pursuers. Half-a-dozen warriors, better mounted than the rest, were some distance ahead. So easy a capture would be that of the unarmed fugitive that they had not troubled to hold a weapon in readiness. Now they began to whirl their lassos ready for a throw.
Vipan, perfectly cool, crouched behind a bush, his revolver pointed. On they came, War Wolf leading, a grin of triumph wreathing his fierce features. A hundred yards—then fifty. A ringing report—a jet of flame in the glooming twilight. War Wolf threw up his arms and lurched heavily forward upon his horse’s neck. The terrified animal, snorting and rearing, dashed away at a tangent, dragging his rider, who had somehow become entangled in the caparisonings.
And what a howl of rage and consternation rent the air! They had not bargained for this, for they believed the fugitive to be unarmed. Panic-stricken for the moment, they halted, then some of them dashed off to the succour of their leader. But they need not have done so. The bullet had sped true. The young partisan had shouted his last war-whoop.
Profiting by this temporary check, the hunted man had again sprung on the back of his horse. Lame or not, the animal must carry him further yet. On—on. The forest belt was gained. He plunged beneath its shadows, only to find it was mere straggling timber—not thick enough for hiding purposes. The frosty air cut his face and the leaves crackled crisply under his horse’s hoofs. He drew his knife and pricked the poor brute furiously in the hinder quarters. The fierce yells of the savages drawing nearer and nearer told only too plainly that they had no intention of relinquishing the pursuit, and the horse was beginning to go dead lame.
“Cau—aak!”
He glanced involuntarily upward. A huge raven disturbed on its roost flapped away in alarm. But another sight met his eye. Extending horizontally from two sturdy limbs of a Cottonwood tree, cleaving the wintry sky, was a long dark object. Vipan recognised one of those platforms on which the Indians deposit their dead—like Mohammed’s coffin, midway between earth and heaven.
