Burl knew these dangers. They were part of his life. It was this knowledge that made life possible. He knew the ways to evade these dangers. But if he yielded to carelessness for one moment, or if he relaxed his caution for one instant, he would be one with his ancestors. They were the long-forgotten meals of inhuman monsters. Now, to be sure, Burl moved upon an errand that probably no other of his tribe would have imagined. The day before, he had crouched behind a shapeless mound of inter-tangled growths and watched a duel between two huge horned beetles. Their bodies were feet long. Their carapaces were waist-high to Burl when they crawled. Their mandibles, gaping laterally, clicked and clashed upon each other's impenetrable armor. Their legs crashed like so many cymbals as they struck against each other. They fought over some particularly attractive bit of carrion. Burl had watched with wide eyes until a gaping hole appeared in the armor of the smaller one. It uttered a grating outcry--or seemed to. The noise was actually the tearing of its shell between the mandibles of the victor. The wounded creature struggled more and more feebly. When it ceased to offer battle, the conqueror placidly began to dine before its prey had ceased to live. But this was the custom of creatures on this planet. Burl watched, timorous but hopeful. When the meal was finished, he darted in quickly as the diner lumbered away. He was almost too late, even then. An ant--the forerunner of many--already inspected the fragments with excitedly vibrating antennae. Burl needed to move quickly and he did. Ants were stupid and short-sighted insects; few of them were hunters. Save when offered battle, most of them were scavengers only. They hunted the scenes of nightmare for the dead and dying only, but fought viciously if their prey were questioned. And always there were others on the way. Some were arriving now. Hearing the tiny clickings of their approach, Burl was hasty. Over-hasty. He seized a loosened fragment and fled. It was merely the horn, the snout of the dead and eaten creature. But it was loose and easily carried. He ran. Later he inspected his find with disappointment. There was little meat clinging to it. It was merely the horn of a Minotaur beetle, shaped like the horn of a rhinoceros. Plucking out the shreds left by its murderer, he pricked his hand. Pettishly, he flung it aside. The time of darkness was near, so he crept to the hiding place of his tribe to huddle with them until light came again. There were only twenty of them; four or five men and six or seven women. The rest were girls or children. Burl had been wondering at the strange feelings that came over him when he looked at one of the girls. She was younger than Burl--perhaps eighteen--and fleeter of foot. They talked together sometimes and, once or twice, Burl shared an especially succulent find of foodstuffs with her.
