busily at work upon its remains. And when he went back to the hiding-place he donned again his great cloak that was made from the wing of a magnificent moth, slain by the flames of the purple hills, and sat down in splendor upon a crumbling toadstool, to feast upon the glances of admiration and awe that were sent toward him. Only Saya held back shyly, until he motioned for her to draw near, when she seated herself at his feet and gazed up at him with unutterable adoration in her eyes. But while Burl basked in the radiance of his tribe's admiration, danger was drawing near them all. For many months there had been strange red mushrooms growing slowly here and there all over the earth, they knew. The tribefolk had speculated about them, but forebore tasting them because they were strange, and strange things were usually dangerous and often fatal. Now those red growths had ripened and grown ready to emit their spores. Their rounded tops had grown fat, and the tough skin grew taut as if a strange pressure were being applied from within. And to-day, while Burl luxuriated in his position of feared and admired great man of his tribe, at a spot a long distance away, upon a hill-top, one of the red mushrooms burst. The spores inside the taut, tough skin shot all about as if scattered by an explosion, and made a little cloud of reddish, impalpable dust, which hung in the air and moved slowly with the sluggish breeze. A bee droned into the thin red cloud of dust, lazily and heavily flying back toward the hive. But barely had she entered the tinted atmosphere when her movements became awkward and convulsive, effortful and excited. She trembled and twisted in mid air in a peculiar fashion, then dropped to the earth, while her abdomen moved violently. Bees, like almost all insects, breathe through spiracles on the undersurfaces of their abdomens. This bee had breathed in some of the red mushroom's spores. She thrashed about desperately upon the toadstools on which she had fallen, struggling for breath, for life. After a long time she was still. The cloud of red mushroom spores had strangled or poisoned her. And everywhere the red fringe grew, such explosions were taking place, one by one, and wherever the red clouds hung in the air creatures were breathing them in and dying in convulsions of strangulation.
