The next second his pulse nearly stopped in sheer panic at having made such a noise. He listened fearfully, but there was no sound. He drew near his prey and carefully withdrew his spear. The viscid liquid made it slimy and slippery, and he had to wipe it dry against a leathery toadstool. Then Burl had to conquer his illogical fear again before daring to touch the creature he had slain. He moved off presently, with the belly of the spider upon his back and two of the hairy legs over his shoulders. The other limbs of the monster hung limp, and trailed upon the ground. Burl was now a still more curious sight as a gayly colored object with a cloak shining in iridescent colors, the golden antennae of a great moth rising from his forehead, and the hideous bulk of a gray spider for a burden. He moved through the thin-stalked mushroom forest, and, because of the thing he carried, all creatures fled before him. They did not fear man--their instinct was slow-moving--but during all the millions of years that insects have existed, there have existed spiders to prey upon them. So Burl moved on in solemn state, a brightly clad man bent beneath the weight of a huge and horrible monster. He came upon a valley full of torn and blackened mushrooms. There was not a single yellow top among them. Every one had been infested with tiny maggots which had liquefied the tough meat of the mushroom and caused it to drip to the ground below. And all the liquid had gathered in a golden pool in the center of the small depression. Burl heard a loud humming and buzzing before he topped the rise that opened the valley for his inspection. He stopped a moment and looked down. A golden-red lake, its center reflecting the hazy sky overhead. All about, blackened mushrooms, seeming to have been charred and burned by a fierce flame. A slow-flowing golden brooklet trickled slowly over a rocky ledge, into the larger pool. And all about the edges of the golden lake, in ranks and rows, by hundreds, thousands, and by millions, were ranged the green-gold, shining bodies of great flies. They were small as compared with the other insects. They had increased in size but a fraction of the amount that the bees, for example, had increased; but it was due to an imperative necessity of their race. The flesh-flies laid their eggs by hundreds in decaying carcases. The others laid their eggs by hundreds in the mushrooms. To feed the maggots that would hatch, a relatively great quantity of food was needed, therefore the flies must remain comparatively small, or the body of a single grasshopper, say, would furnish food for but two or three grubs instead of the hundreds it must support.
