It was then drawing toward the time of darkness, but one of the tribesmen had ventured out and found no less than three of the great imperial mushrooms. Of the three, one had been attacked by a parasitic purple mould, but the gorgeous yellow of the other two was undimmed, and the people were soon feasting upon the firm flesh. Burl felt a little pang of jealousy, though he joined in the consumption of the find as readily as the others, and presently drew a little to one side. He cast his eyes across the country, level and unbroken as far as the eye could see. The small clay cliff was the only inequality visible, and its height cut off all vision on one side. But the view toward the horizon was unobstructed on three sides, and here and there the black speck of a monster bee could be seen, droning homeward to its hive or burrow, and sometimes the slender form of a wasp passed overhead, its transparent wings invisible from the rapidity of their vibrations. These flew high in the air, but lower down, barely skimming the tops of the many-colored mushrooms and toadstools, fluttering lightly above the swollen fungoids, and touching their dainty proboscides to unspeakable things in default of the fragrant flowers that were normal food for their races--lower down flew the multitudes of butterflies the age of mushrooms had produced. White and yellow and red and brown, pink and blue and purple and green, every shade and every color, every size and almost every shape, they flitted gaily in the air. There were some so tiny that they would barely have shaded Burl's face, and some beneath whose slender bodies he could have hidden himself. They flew in a riot of colors and tints above a world of foul mushroom growths, and turgid, slime-covered ponds. Burl, temporarily out of the limelight because of the discovery of a store of food by another member of the tribe, bethought himself of an idea. Soon night would come on, the cloud-bank would turn red in the west, and then darkness would lean downward from the sky. With the coming of that time these creatures of the day would seek hiding-places, and the air would be given over to the furry moths that flew by night. He, Burl, would mark the spot where one of the larger creatures alighted, and would creep up upon it, with his spear held fast. His wide blue eyes brightened at the thought, and he sat himself down to watch. After a long time the soft, down-reaching fingers of the night touched the shaded aisles of the mushroom forests, and a gentle haze arose above the golden glades. One by one the gorgeous fliers of the daytime dipped down and furled their painted wings. The overhanging clouds became darker--finally black, and the slow, deliberate rainfall that lasted all through the night began. Burl rose and crept away into the darkness, his spear held in readiness.
