Stephens patted and encouraged him, making him understand that there was game afoot, and, warily as if stalking a deer, took him back to where White Antelope lay stiff and stark. As he smelt the blood again Faro growled and his bristles rose; his master encouraged him till the dog knew what he meant; the game they were after was not deer—it was men. He took up the scent of the two Navajos who had escaped into the rocks, and followed it with his hackles erect. In and out among the labyrinth of tumbled rocks he led the way, and Stephens kept up with him as best he could without exposing himself too recklessly. The trail grew hotter and hotter, till on a sudden Faro turned sharply aside and dashed out of sight behind a huge boulder; instantly there followed his loud, angry bark, and a half-stifled cry of human rage.

With his rifle raised nearly to his shoulder, Stephens put his head round the angle of the boulder, to see an Indian standing almost within arm's length of him with his back against the rock, angrily striking with his gun at the dog, who was baying furiously as he sprang from side to side to avoid the blows. Stephens had no time to look around to see where the other redskin was, for at sight of him the Navajo, disregarding the dog, raised his rifle and fired, and the Winchester cracked almost in the same instant. So close were the two to one another that the burst of flame and powder smoke from the Indian's piece momentarily blinded the American.

"I must be done for now," was the despairing thought that flashed through his mind in the utter helplessness of loss of sight; yet he felt no wound, and blind as he was he instinctively threw in a fresh cartridge for a second shot. Then his smarting eyes began to recover themselves; hope came back; he was not blinded; he found himself able to see again, though with difficulty; and there at his feet was the body of the Navajo and the dog worrying him. He flung himself on the pair to protect, if need be, his ever faithful ally, but need was none. His bullet had gone home, and the Navajo was sped. He dragged the infuriated bulldog from his prey.

"Luck's all," said he, dashing the water from his eyes. "I don't know how I came to plug him so squarely; I never even saw the sights; I thought I was a goner that journey, sure."

He looked around with restored vision to try if he could descry the last of the gang, but there was no sign of him visible; it seemed as if the pair must either have separated somehow before he and Faro came up to their hiding-place, or else the survivor had fled on his companion's fall.

"And that's lucky for me, too," said Stephens, "for he could just have socked it into me as he liked when I was blinded with all that powder smoke."

"Come on then, Faro," he continued, patting the dog, and encouraging him to take up the trail again. "One more, and our job's done. Hie on, old man, he can't be far away."

With eager pride the dog began questing anew for the scent, nosing inquisitively to right and to left, and Stephens, as before, followed him warily. They did not have to go far before the dog's stiffening bristles showed that the enemy was near. Three great detached masses of stone, fallen together haphazard, so bore against each other as to leave underneath a low, dark, cavernous recess, and into the mouth of this the dog dashed without a pause. The fierce sounds of conflict that instantly followed proved that it was the hiding-place of the hunted man.

For one anxious moment Stephens doubted whether to shoot or no, but standing outside in the bright light he could see nothing clear in the dark recess, and to shoot at random into it was to hazard killing his own friend. Then there came a loud howl from Faro, and unhesitatingly he drew his knife, dropped on all-fours, and laying the rifle aside threw himself head first into the cave, and in the darkness grappled for his foe. His left hand, thrust forward, seized an arm of the other, and swiftly in reply came the sharp, cold pang of a knife drawn across the back of it, and the warm gush of blood following the cut. As he felt the wound, his right hand instinctively let go of his own knife and seized the wrist of the hand wielding the blade that had cut him, the redskin frantically striving to get the hand free to deal him a fatal stab.
