When they came to an unusually large and attractive clump of golden edible mushrooms, there were murmurings. Old Jon was inclined to go and load himself and retire to some hiding-place for as long as the food lasted. But Burl snarled again.
Numbly they followed on—Dor and Jon and Jak and the two youngsters. The ground inclined upward. They came upon puffballs. There was a new kind visible, colored a lurid red, that did not grow like the others. It seemed to begin and expand underground, then thrust away the soil above in its development. Its taut, angry-red parchment envelope seemed to swell from a reservoir of subterranean material. Burl and the others had never seen anything like it.
They climbed higher. As other edible mushrooms came into view Burl's followers cheered visibly. This was a new tribal ground anyhow and it had not been fully explored. But Burl was leading them to quantities of food they had never suspected before.
Quaintly, it was Burl himself who began to feel an uncomfortable dryness in his throat. He knew what he was about. His followers did not suspect because to them what he intended was simply inconceivable. They couldn't suspect it because they couldn't imagine anybody doing such a thing. It simply couldn't be thought of at all.
It is rather likely that Burl began to regret that he had thought of it. It had come to him first as an angry notion in the night. Then the idea had developed as a suitable punishment for his abandonment. By dawn it was an ambition so terrifying that it fascinated him. Now he was committed to it in his own mind, and the only way to keep his knees from knocking together was to keep moving. If his followers had protested now, he would have allowed himself to be persuaded. But he heard more pleased murmurs. There was more edible stuff, in quantity. But there were no ant-trails here, no sounds of foraging beetles. This was an area which Burl's tribesmen could clearly see was almost devoid of dangerous life. They seemed to brighten a little. This, they seemed to think, would be a good place to move to.
But Burl knew better. There were few ground-insects here because the area was hunted out. And Burl knew what had done the hunting.
He expected the others to realize where they were when they dodged around a clump of the new red puffballs and saw bald rock before them and a falling-away to emptiness beyond. Even then they could have retreated, but it did not enter their heads that Burl could do anything like this.
They didn't know where they were until Burl held up his hand for silence almost at the edge of the rock-knob which rose a hundred feet sheer, curving out a little near its top. They looked out uncomprehendingly at the mist-filled air and the nightmare landscape fading into its grayness. A tiny spider, the very youngest of hatchlings and barely four inches across, stealthily stalked another vastly smaller mite. The other was the many-legged larva of the oil-beetle. The larva itself had been called—on other planets by other men—the bee-louse. It could easily hide in the thick furl of a giant bumble-bee. But this one small creature never practiced that ability. The hatchling spider sprang and the small midge died. When the spider had grown and, being grown, spun a web, it would slay great crickets with the same insane ferocity.
Burl's followers saw first this and then certain three-quarter-inch strands of dirty silk that came up over the edge of the precipice. As one man after another realized where he was, he trembled violently. Dor turned gray. Jon and Jak were paralyzed with horror. They couldn't run.
Seeing the others even more frightened than himself filled Burl with a wholly unwarranted courage. When he opened his mouth, they cringed. If he shouted then at least one, more likely several, of them would die.
