This was the trap of a labyrinth spider. Not one of the interlacing strands was strong enough to hold any but the feeblest prey, but the threads were there by thousands. A cricket had become entangled in the sticky maze. Its limbs thrashed out and broke threads with every stroke, but each time became entangled in a dozen more. It struggled mightily, emitting at intervals—again—its horrible bass roar.
Burl breathed more easily. He watched with fascinated eyes. Mere death among insects—even tragic death—held no great interest for him. It was too common an occurrence. And there were few insects which deliberately sought man. Most insects have their allotted prey and will seek no others.
But this involved a spider, and spiders have a terrifying impartiality. A spider devouring some luckless insect was but an example of what might happen to Burl. So he watched alertly, his eyes traveling from the enmeshed cricket to the strange opening at the back of the funnel-shaped labyrinth.
That opening darkened. Two shining, glistening eyes had been watching from the tunnel in which the spider had been waiting. Now it swung out lightly, revealing itself as a gray spider, with twin black ribbons upon its thorax and two stripes of curiously speckled brown and white upon its abdomen. Burl saw, also, two curious appendages like a tail, as it came nimbly out of its hiding-place and approached the trapped creature.
The cricket was struggling weakly, now, and the cries it uttered were but feeble, because of the cords that fettered its limbs. Burl saw the spider throw itself upon the cricket which gave one final, convulsive shudder as fangs pierced its armor.
Shortly after, the spider fed. With bestial enjoyment it sucked all the succulence, all the fluid, from its victim's carcass.
Then the breath left Burl in a peculiar, frightened gasp. It was not from anything he saw or heard. It was something that he thought.
For a second, his knees knocked together in self-induced panic. It occurred to him that he, Burl, had killed a hunting spider—a tarantula—upon the red-clay cliff. True, the killing had been an accident and had nearly cost him his own life in the web-spider's snare. But—he had killed a spider and of the most deadly kind. Now it occurred to Burl that he could kill another.
Spiders were the ogres of the human tribes on the forgotten planet. Knowledge of them was hard to come by, because to study them was death. But all men knew that web-spiders never left their traps. Never! And Burl had imagined himself making an impossibly splendid, incredibly daring use of that fact.
Denying to himself that he intended any action so suicidal, he nevertheless drew back from the front of the snare and made his way to the back, where the spider's tunnel was no more than ten feet away.
