He watched, raging, for the sight that would provide him with the triumph to end all triumphs among his followers. The soft, down-reaching fingers of the night touched here and there and the day ended at those spots. Then, from the heart of the deep redness to the west a flying creature came. It was a beautiful thing--a yellow emperor butterfly--flapping eastward with great sail-like velvet wings that seemed black against the sunset. Burl saw it sweep across the incredible sky, alight delicately, and disappear behind a mass of toadstools clustered so thickly they seemed nearly a hillock and not a mass of growing things. Then darkness closed in completely, but Burl still stared where the yellow emperor had landed. There was that temporary, utter quiet when day-things were hidden and night-things had not yet ventured out. Fox-fire glowed. Patches of pale phosphorescence--luminous mushrooms--shone faintly in the dark. Presently Burl moved through the night. He could imagine the yellow emperor in its hiding-place, delicately preening slender limbs before it settled down to rest until the new day dawned. He had noted landmarks, to guide himself. A week earlier and his blood would have run cold at the bare thought of doing what he did now. In mere cool-headed detachment he would have known that what he did was close to madness. But he was neither cool-headed nor detached. He crossed the clear ground before the low cliff. But for the fox-fire beacons he would have been lost instantly. The slow drippings of rain began. The sky was dead black. Now was the time for night-things to fly, and male tarantulas to go seeking mates and prey. It was definitely no time for adventuring. Burl moved on. He found the close-packed toadstools by the process of running into them in the total obscurity. He fumbled, trying to force his way between them. It could not be done; they grew too close and too low. He raged at this impediment. He climbed. This was insanity. Burl stood on spongy mushroom-stuff that quivered and yielded under his weight. Somewhere something boomed upward, rising on fast-beating wings into blackness. He heard the pulsing drone of four-inch mosquitos close by. He moved forward, the fungus support swaying, so that he did not so much walk as stagger over the close-packed mushroom heads. He groped before him with spear and panted a little. There was a part of him which was bitterly afraid, but he raged the more furiously because if once he gave way even to caution, it would turn to panic. Burl would have made a strange spectacle in daylight gaudily clothed as he was in soft blue fur and velvet cloak, staggering over swaying insecurity, coddling ferocity in himself against the threat of fear. Then his spear told him there was emptiness ahead. Something moved, below. He heard and felt it stirring the toadstool-stalks on which he stood. Burl raised his spear, grasping it in both hands. He plunged down with it, stabbing fiercely.
