All at once one of their number rose from the ground with a faint whinney, and came trotting toward him. At the same time several Indians came forward from the main group, their suspicions fairly awakened by these maneuvers. One of these suddenly broke into a run, as he descried the mustang trotting toward the warrior-like figure shrouded in his blanket. There was no doubt in his mind that something was wrong. The scout stood like a statue, as though he saw not the approach of the man or horse. The latter as if distrustful of the shape of things moved so reluctantly that the redskin beat him in reaching the goal. "What means Mau-tau-ke?" he demanded, in a gruff voice, as he clutched his shoulder. "Is he a dog that--" The poor Apache scarcely knew what disposed of him. It was with the suddenness of the lightning stroke, and, flinging back the dirty blanket that had enshrouded his form, the scout pointed his revolvers at the others, fired three shots, accompanied by a screech loud enough to wake the dead. Then, springing toward his mustang, he vaulted upon his back, wheeled about, and thundered away, like the whirlwind across the prairie. This demonstration was so unexpected and so appalling that the Apaches were effectually checked for a time. Before they could recover, mount their horses, and start in pursuit, the fugitive was beyond their sight. It was useless to pursue, at any rate, for there was no steed among them all that could overtake the flying mustang, whose hoofs were plainly heard upon the prairie, rapidly growing fainter as the distance increased. In a few minutes it had died out altogether, and, ferocious as was the hatred of the redskins toward the hunter who had outwitted and injured them so often, no one made any effort to overhaul him. Tom Hardynge, every few seconds, let out a regular Apache war-yell, intended as exultation, taunt and defiance. He could afford it, for he had triumphed as completely as heart could covet. The magnificent Thundergust instinctively knew their destination, and the reins lay loosely upon his neck as he sped away. He was aiming for Fort Havens. It was a long distance away, and many hours must pass before its flagstaff could be detected against the far-off horizon. CHAPTER XXXVII. THE TWO DEFENDERS. Dick Morris, stretched out full length upon the top of Hurricane Hill, peering down in the impenetrable gloom, understood all that had passed. There was no mistaking that yell of Tom Hardynge; he had heard it many a time before in the heat of conflict, and it generally meant something. "Go it, old chap!" he shouted, swinging his hat over his head, as he saw the whole thing in his imagination. "Them 'ere pistol-barks show there's been some bitin' done. Business is business."
