The tarantula, peering from its burrow, quivered with impatience. Burl drew near, and nearer. He was using his spear as a lever, now, and prying off bits of fungus to fall down the cliffside into the colossal web. The spider, below, went leisurely from one place to another, investigating each new missile with its palpi, then leaving them, as they appeared lifeless and undesirable prey. Burl laughed again as a particularly large lump of shelf-fungus narrowly missed the black-and-silver figure below. Then-- The trap door fell into place with a faint click, and Burl whirled about. His laughter turned to a scream. Moving toward him with incredible rapidity, the monster tarantula opened its dripping jaws. Its mandibles gaped wide. The poison fangs were unsheathed. The creature was thirty paces away, twenty paces--ten. It leaped into the air, eyes glittering, all its eight legs extended to seize, fangs bared-- Burl screamed again, and thrust out his arms to ward off the impact of the leap. In his terror, his grasp upon his spear had become agonized. The spear point shot out, and the tarantula fell upon it. Nearly a quarter of the spear entered the body of the ferocious thing. It struck upon the spear, writhing horribly, still struggling to reach Burl, who was transfixed with horror. The mandibles clashed, strange sounds came from the beast. Then one of the attenuated, hairy legs rasped across Burl's forearm. He gasped in ultimate fear and stepped backward--and the edge of the cliff gave way beneath him. He hurtled downward, still clutching the spear which led the writhing creature from him. Down through space, eyes glassy with panic, the two creatures--the man and the giant tarantula--fell together. There was a strangely elastic crash and crackling. They had fallen into the web beneath them. Burl had reached the end of terror. He could be no more fear-struck. Struggling madly in the gummy coils of an immense web, which ever bound him more tightly, with a wounded creature shuddering in agony not a yard from him--yet a wounded creature that still strove to reach him with its poison fangs--Burl had reached the limit of panic. He fought like a madman to break the coils about him. His arms and breast were greasy from the oily fish, and the sticky web did not adhere to them, but his legs and body were inextricably fastened by the elastic threads spread for just such prey as he. He paused a moment, in exhaustion. Then he saw, five yards away, the silvery and black monster waiting patiently for him to weary himself. It judged the moment propitious. The tarantula and the man were one in its eyes, one struggling thing that had fallen opportunely into its snare. They were moving but feebly now. The spider advanced delicately, swinging its huge bulk nimbly along the web, paying out a cable after it came inexorably toward him.
