He found a caterpillar wrapped in its thick cocoon and, because he was not foraging and not particularly hungry, he inspected it with care. With great difficulty he even broke the strand of silk that formed it, unreeling several feet in curiosity. Had he meditated, Burl would have seen that this was cord which could be used to build snares as spiders did. It could also be used to make defenses in which--if built strongly and well--even hunting-spiders might be tangled and dispatched. But again he was not knowingly looking for things to be of use. He coddled his sense of injury against the tribe. He punished them by leaving them. He encountered a four-foot praying-mantis that raised its saw-toothed forelimbs and waited immobile for him to come within reach. He had trouble getting away without a fight. His spear would have been a clumsy weapon against so slender a target and the club certainly not quick enough to counter the insect's lightning-like movements. He was bothered. That day he hunted ants. The difficulty was mainly that of finding individual ants, alone, who could be slaughtered without drawing hordes of others into the fight. Before nightfall he had three of them--foot-long carcasses--slung at his belt. Near sunset he came upon another fairly recent praying-mantis hatchling. It was almost an ambush. The young monster stood completely immobile and waited for him to walk into its reach. Burl performed a deliberate experiment--something that had not been done for a very long time on the forgotten planet. The small, grisly creature stood as high as Burl's shoulders. It would be a deadly antagonist. Burl tossed it a dead ant. It struck so swiftly that the motion of its horrible forearms could not be seen. Then it ignored Burl, devouring the tidbit. It was a discovery that was immediately and urgently useful. On the second day of his aimless journey Burl saw something that would be even more deadly and appalling than the red dust had been for his kind. It was a female black hunting-spider, the so-called American tarantula. When he glimpsed the thing the blood drained from Burl's face. As the monster moved out of sight Burl, abandoning any other project he might have intended, headed for the place his tribe had more or less settled in. He had news which offered the satisfaction of making him much-needed again, but he would have traded that pleasure ten hundred times over for the simple absence of that one creature from this valley. That female tarantula meant simply and specifically that the tribe must flee or die. This place was not paradise!
