Not fifty paces away he saw an enormous wolf.

It stood stock-still, as if caught in the act of stealthy movement, and Dusty Star noticed with uneasiness that between them there was no obstacle or cover of any kind. A couple of swift bounds and the creature could be upon him. Instinctively he realized that it had been stalking him for some time, and was now preparing for the final rush.

For a moment his heart failed him. Then he rallied. Face to face with the Terror of the Carboona, Dusty Star did not flinch. The fine Indian breed of him, descending through long generations, rose magnificently to the test.

He took in his surroundings with a glance. On one hand lay a pool; on the other, a tangle of bushes. Behind him, the ground rose. He waited for the wolf to make the first movement.

For a moment or two, Lone Wolf remained in the half crouching attitude in which he had been surprised. Then, snarling threateningly he began to move slowly forward.

Dusty Star drew his hunting-knife in readiness, and stood his ground. The wolf continued to advance. When not more than a dozen paces separated them, he stopped again. Dusty Star noted the cruel light in his eyes, and knew that he paused for the first spring of the attack. Yet his own gaze did not falter. He held the wolf boldly with his eyes. Never before had Lone Wolf borne the direct stare of the human eye face to face, and the experience made him uneasy. He felt the presence of a mysterious power out of all proportion to the body which contained it. His own eyes glittering with evil as they were, lacked this power. He was fully conscious of his own importance—a great wolf, lord of a wide range; yet some unexplained feeling within him told him that he was now in the presence of a creature greater than himself. For all that, he knew that this new enemy must be attacked, and his right to enter Carboona challenged. For he felt that here, though he could not understand it, was a challenge from the wolves.

Without further warning, he sprang. In the same instant, Dusty Star leaped aside, escaping by a hair's breath the slash of the wolf's fangs at his throat. But he had not been able to leap quite far enough, and, though he tried to save himself he fell. As he did so, he drove his hunting-knife with all his force into the wolf's side.

What happened next was like a thunderbolt from a blue sky.

As the keen blade went home, Lone Wolf yelped and turned furiously on his fallen foe; but before he could slash a second time, a huge black body bounded through the air from the tangle of bushes on the right. The thing was so utterly unexpected that the wolf was completely taken off his guard. The great body, descending full upon him, bore him to the ground.

If his assailant could have kept its hold, the reign of the Lone Wolf, mightily sinewed though he was, would have been over for ever; but the force of the creature's landing had been so great that it slightly lost its balance. That slight loss saved the wolf's life. With a snarl of mingled rage and pain, he tore himself from his enemy's clutch with a tremendous wrench; then, not daring to face those terrible claws again, he bounded off across the barren, leaving a trail of blood.
