Target broke the spell by swinging me up into the saddle as he leaped forward with a furious snort. I struck him with the bridle, and yelled: “You iron-jawed brute! You've been crazy to run--now run!” XVII. THE BACK-FIRE Target pounded over the scaly ground and thundered into the hard trail. Then he stretched out. As we cleared the last obstructing pile of rocks I looked back. There was a vast wave of fire rolling up the canyon and spreading up the slopes. It was so close that I nearly fainted. With both hands knotted and stiff I clung to the pommel in a cold horror, and I looked back no more to see the flames reaching out for me. But I could not keep the dreadful roar from filling my ears, and it weakened me so that I all but dropped from the saddle. Only an unconscious instinct to fight for life made me hold on. Blue and white puffs of smoke swept by me. The trail was a dim, twisting line. The slopes and pines, merged in a mass, flew backward in brown sheets. Above the roar of the pursuing fire I heard the thunder of Target's hoofs. I scarcely felt him or the saddle, only a motion and the splitting of the wind. The fear of death by fire, which had almost robbed me of strength, passed from me. My brain cleared. Still I had no kind of hope, only a desperate resolve not to give up. The great bay horse was running to save his life and to save mine. It was a race with fire. When I thought of the horse, and saw how fast he was going, and realized that I must do my part, I was myself again. The trail was a winding, hard-packed thread of white ground. It had been made for leisurely travel. Many turns were sudden and sharp. I loosened the reins, and cried out to Target. Evidently I had unknowingly held him in, for he lengthened out, and went on in quicker, longer leaps. In that moment riding seemed easy. I listened to the roar behind me, now a little less deafening, and began to thrill. We were running away from the fire. Hope made the race seem different. Something stirred and beat warm within me, driving out the chill in my marrow. I leaned over the neck of the great bay horse, and called to him and cheered him on. Then I saw he was deaf and blind to me, for he was wild. He had the bit between his teeth, and was running away.
