Slone fought the desire to look back. But he could not resist it. Some horrible fascination compelled him. All behind had changed. A hot wind, like a blast from a furnace, blew light, stinging particles into his face. The fire was racing in the tree-tops, while below all was yet clear. A lashing, leaping flame engulfed the canopy of pines. It was white, seething, inconceivably swift, with a thousand flashing tongues. It traveled ahead of smoke. It was so thin he could see the branches through it, and the fiery clouds behind. It swept onward, a sublime and an appalling spectacle. Slone could not think of what it looked like. It was fire, liberated, freed from the bowels of the earth, tremendous, devouring. This, then, was the meaning of fire. This, then, was the horrible fate to befall Lucy. But no! He thought he must be insane not to be overcome in spirit. Yet he was not. He would beat the flame to Lucy. He felt the loss of something, some kind of a sensation which he ought to have had. Still he rode that race to kill his sweetheart better than any race he had ever before ridden. He kept his seat; he dodged the snags; he pulled the maddened horse the shortest way, he kept the King running straight. No horse had ever run so magnificent a race! Wildfire was outracing wind and fire, and he was overhauling the most noted racer of the uplands against a tremendous handicap. But now he was no longer racing to kill the King; he was running in terror. For miles he held that long, swift, wonderful stride without a break. He was running to his death, whether or not he distanced the fire. Nothing could stop him now but a bursting heart. Slone untied his lasso and coiled the noose. Almost within reach of the King! One throw--one sudden swerve--and the King would go down. Lucy would know only a stunning shock. Slone's heart broke. Could he kill her--crush that dear golden head? He could not, yet he must! He saw a long, curved, red welt on Lucy's white shoulders. What was that? Had a branch lashed her? Slone could not see her face. She could not have been dead or in a faint, for she was riding the King, bound as she was! Closer and closer drew Wildfire. He seemed to go faster and faster as that wind of flame gained upon them. The air was too thick to breathe. It had an irresistible weight. It pushed horses and riders onward in their flight--straws on the crest of a cyclone.
