Burl's grandfather had been careless, and the terrible shrieks he uttered as the horrible monster darted from the pit and seized him had lingered vaguely in Burl's mind ever since. Burl had seen, too, the monster webs of another species of spider, and watched from a safe distance as the misshapen body of the huge creature sucked the juices from a three-foot cricket that had become entangled in its trap. Burl had remembered the strange stripes of yellow and black and silver that crossed upon its abdomen (_Epiera fasciata_). He had been fascinated by the struggles of the imprisoned insect, coiled in a hopeless tangle of sticky, gummy ropes the thickness of Burl's finger, cast about its body before the spider made any attempt to approach. Burl knew these dangers. They were a part of his life. It was his accustomedness to them, and that of his ancestors, that made his existence possible. He was able to evade them; so he survived. A moment of carelessness, an instant's relaxation of his habitual caution, and he would be one with his forebears, forgotten meals of long-dead, inhuman monsters. Three days before, Burl had crouched behind a bulky, shapeless fungus growth while he watched a furious duel between two huge horned beetles. Their jaws, gaping wide, clicked and clashed upon each other's impenetrable armor. Their legs crashed like so many cymbals as their polished surfaces ground and struck against each other. They were fighting over some particularly attractive bit of carrion. Burl had watched with all his eyes until a gaping orifice appeared in the armor of the smaller of the two. It uttered a shrill cry, or seemed to cry out. The noise was, actually, the tearing of the horny stuff beneath the victorious jaws of the adversary. The wounded beetle struggled more and more feebly. At last it collapsed, and the conqueror placidly began to eat the conquered before life was extinct. Burl waited until the meal was finished, and then approached the scene with caution. An ant--the forerunner of many--was already inspecting the carcass. Burl usually ignored the ants. They were stupid, short-sighted insects, and not hunters. Save when attacked, they offered no injury. They were scavengers, on the lookout for the dead and dying, but they would fight viciously if their prey were questioned, and they were dangerous opponents. They were from three inches, for the tiny black ants, to a foot for the large termites. Burl was hasty when he heard the tiny clickings of their limbs as they approached. He seized the sharp-pointed snout of the victim, detached from the body, and fled from the scene.
