There was a reason which nobody in the tribe would ever remember to associate with the significance of this banquet. A long time before--months in terms of Earth-time--there had been a strong breeze that blew for three days and nights. It was an extremely unusual windstorm. It had seemed the stranger, then, because during all its duration everyone in the tribe had been sick, suffering continuously. When the windstorm had ended, the suffering ceased. A long time passed and nobody remembered it any longer. There was no reason why they should. Yet, since that time there had been a new kind of thing growing among the innumerable moulds and rusts and toadstools of the lowlands. Burl had seen them on his travels, and the expeditionary force against the clotho spider had seen them on the journey up to the cliff-edge. Red puffballs, developing first underground, were now pushing the soil aside to expose taut, crimson parchment spheres to the open air. The tribesmen left them alone because they were strange; and strange things were always dangerous. Puffballs they were familiar with--big, misshapen things which shot at a touch a powder into the air. The particles of powder were spores--the seed from which they grew. Spores had remained infinitely small even on the forgotten planet where fungi grew huge. Only their capacity for growth had increased. The red growths were puffballs, but of a new and different kind. As the tribe ate and admired, the hunters boasting of their courage, one of the new red mushrooms reached maturity. This particular growing thing was perhaps two feet across, its main part spherical. Almost eighteen inches of the thing rose above-ground. A tawny and menacing red, the sphere was contained in a parchment-like skin that was pulled taut. There was internal tension. But the skin was tough and would not yield, yet the inexorable pressure of life within demanded that it stretch. It was growing within, but the skin without had ceased to grow. This one happened to be on a low hillside a good half-mile from the place where Burl and his fellows banqueted. Its tough, red parchment skin was tensed unendurably. Suddenly it ripped apart with an explosive tearing noise. The dry spores within billowed out and up like the smoke of a shell-explosion, spurting skyward for twenty feet and more. At the top of their ascent they spread out and eddied like a cloud of reddish smoke. They hung in the air. They drifted in the sluggish breeze. They spread as they floated, forming a gradually extending, descending dust-cloud in the humid air. A bee, flying back toward its hive, droned into the thin mass of dust. It was preoccupied. The dust-cloud was not opaque, but only a thick haze. The bee flew into it.
