Darkness. The soft, blanketing night of the age of fungoids had fallen over all the earth, and there was blackness everywhere that was not good to have. Here and there, however, dim, bluish lights glowed near the ground. There an intermittent glow showed that a firefly had wandered far from the rivers and swamps above which most of his kind now congregated. Now a faintly luminous ball of fire drifted above the steaming, moisture-sodden earth. It was a will-o'-the-wisp, grown to a yard in diameter. From the low-hanging banks of clouds that hung perpetually overhead, large, warm raindrops fell ceaselessly. A drop, a pause, and then another drop, added to the already dank moisture of the ground below. The world of fungus growths flourished on just such dampness and humidity. It seemed as if the toadstools and mushrooms could be heard, swelling and growing large in the darkness. Rustlings and stealthy movements sounded furtively through the night, and from above the heavy throb of mighty wing-beats was continuous. The tribe was hidden in the midst of a tangled copse of toadstools too thickly interwoven for the larger insects to penetrate. Only the little midgets hid in its recesses during the night-time, and the smaller moths during the day. About and among the bases of the toadstools, however, where their spongy stalks rose from the humid earth, small beetles roamed, singing cheerfully to themselves in deep bass notes. They were small and round, some six or eight inches long, and their bellies were pale gray. And as they went about they emitted sounds which would have been chirps had they been other than low as the lowest tone of a harp. They were truffle-beetles, in search of the dainty tidbits on which epicures once had feasted. Some strange sense seemed to tell them when one of half a dozen varieties of truffle was beneath them, and they paused in their wandering to dig a tunnel straight down. A foot, two feet, or two yards, all was the same to them. In time they would come upon the morsel they sought and would remain at the bottom of their temporary home until it was consumed. Then another period of wandering, singing their cheerful song, until another likely spot was reached and another tunnel begun. In a tiny, open space in the center of the toadstool thicket the tribefolk slept with the deep notes of the truffle-beetles in their ears. A new danger had come to them, but they had passed it on to Burl with a new and childlike confidence and considered the matter settled. They slept, while beneath a glowing mushroom at one side of the clearing Burl struggled with his new problem. He squatted upon the ground in the dim radiance of the shining toadstool, his moth-wing cloak wrapped about him, his spear in his hand, and his twin golden plumes of the moth's antennæ bound to his forehead. But his face was downcast as a child's.
