And he turned to face ahead. The stallion stretched low on a dead run; the tips of the pines were bending before the wind; and Wildfire, the terrible thing for which his horse was named, was leaping through the forest. But there was no sound.
Ahead of Slone, down the aisles, low under the trees spreading over the running King, floated swiftly some medium, like a transparent veil. It was neither smoke nor air. It carried faint pin points of light, sparks, that resembled atoms of dust floating in sunlight. It was a wave of heat driven before the storm of fire. Slone did not feel pain, but he seemed to be drying up, parching. And Lucy must be suffering now. He goaded the stallion, raking his flanks. Wildfire answered with a scream and a greater speed. All except Lucy and Sage King and Wildfire seemed so strange and unreal—the swift rush between the pines, now growing ghostly in the dimming light, the sense of a pursuing, overpowering force, and yet absolute silence.
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.
Again Slone looked back and again the spectacle was different. There was a white and golden fury of flame above, beautiful and blinding; and below, farther back, an inferno of glowing fire, black-streaked, with trembling, exploding puffs and streams of yellow smoke. The aisles between the burning pines were smoky, murky caverns, moving and weird. Slone saw fire shoot from the tree-tops down the trunks, and he saw fire shoot up the trunks, like trains of powder. They exploded like huge rockets. And along the forest floor leaped the little flames. His eyes burned and blurred till all merged into a wide, pursuing storm too awful for the gaze of man.
Wildfire was running down the King. The great gray had not lessened his speed, but he was breaking. Slone felt a ghastly triumph when he began to whirl the noose of the lasso round his head. Already he was within range. But he held back his throw which meant the end of all. And as he hesitated Wildfire suddenly whistled one shrieking blast.
Slone looked. Ahead there was light through the forest! Slone saw a white, open space of grass. A park? No—the end of the forest! Wildfire, like a demon, hurtled onward, with his smoothness of action gone, beginning to break, within a length of the King.
