The Indians were about to leave the neighborhood where they had been so roughly used by the whites. A number had already gone, bearing with them the dead and wounded, and the remainder were about to depart--that is, for a time, until their forces could be marshaled into a body that would sweep New Boston from the face of the earth. Such was the decree of Lone Wolf. Was he to permit a party of white men to plant a settlement in the very heart of his country? Was he to allow his hunting grounds to be appropriated in this fashion? Was he to submit quietly to the encroachments of those who had never so much as asked his consent? Not so long as he could summon an army of the best warriors of the Southwest to his command. If his present company had been too small, then he would double and treble it. At all events, the power would be provided to accomplish his purpose. The horsemen speedily arranged themselves; the head of all turned in a northerly direction. It took some minutes for them to arrange themselves, but they were about ready to receive the command of their chief, when the report of a rifle broke upon the stillness. An Indian, with a spasmodic shriek, threw up his arms and rolled backward, and then from his steed, which snorted and reared, as if it, too, had suffered some injury. This warrior was directly in the rear of Lone Wolf, and had been so fairly in line with him that there could be no doubt that the bullet had really been intended for the chief. The point from whence it came could not be mistaken. Over half of the war-party saw the flash of the gun, off to their right, in the direction of the settlement, and those who chanced not to see it were quickly informed of the spot by the appearance of a horse, looking as if he had sprung from the ground itself. No rider was visible; but, of course, he was there, as he had just demonstrated by means of his shot. That there might be no doubt of his identity, he uttered a loud yell, like that with which one Indian defies another, and called out in the Apache tongue: “Sut Simpson sends the shot for the heart of Lone Wolf, who is a dog and a coward.” This was the favorite taunt of the hunter when he sought to draw out his old enemy. Some of the numerous scars which he received were the direct result of his daring defiance, and he was hopeful that the challenge would accomplish something in the present case. Nor was he disappointed. CHAPTER X. TWO OLD ENEMIES
