Another edge. The man knelt quickly, tremblingly, and, holding tight, let himself over. It was a long drop to the next level. The man waited until his body was swinging inward, then let go. Just before he fell, he saw the great spider scrabbling down the orange slope at him.

He landed on his feet and toppled forward on the hard wood. Pain drove needles up his right ankle. He struggled to his feet; he couldn't stop. Overhead, he heard the spider's scratching. Running to the edge, he hesitated, then jumped into space again. The arm-thick curve of the metal wicket flashed up at him. He grabbed for it.

He fell with a fluttering of anus and legs. The canyon floor rushed up at him. He had to miss the flower patched softness.

And yet he didn't. Almost at the edge of it, he landed feet first and bounced over backward in a neck-snapping somersault.

He lay on his stomach and chest, breathing in short, strangled bursts. There was a smell of dusty cloth in his nostrils, and fabric was rough against his cheek.

Alertness returned then and, with a spasmodic wrenching of muscles, the man looked up and saw another ghostlike cable being spun into the air. In a few moments, he knew, the spider would ride it down.

Pushing up with a groan, he stood a moment on trembling legs. The ankle still hurt, breathing was a strain, but there were no broken bones. He started off.

Hobbling quickly across the flower splotched softness, the man lowered himself across the edge. As he did so, he saw the spider swinging down, a terrible, wriggling pendulum.

He was on the floor of the canyon now. He ran, limping across the wide plain of it, his sandals flopping on the levelled hardness. To his right loomed the vast brown tower in which the flame still burned, the very canyon trembling with its roar.

He glanced behind. The spider was dropping to the flower-covered softness now, then rushing for the edge. The man raced on toward the great log pile, which was half as high as the tower itself. He ran by what looked like a giant, coiled serpent, red and still and open-jawed at either end.

The spider hit the canyon floor and ran at the man.

But the man had reached the gigantic logs now, and, falling forward on his chest, he wriggled into a narrow space between two of them. It was so narrow he could hardly move; dark, damp, cold, and smelling of mouldy wood. He crawled and twisted in as far as he could, then stopped and looked back.

The black, shiny-cased spider was trying to follow him.

For a horrible moment, the man thought it was succeeding. Then he saw that it was stuck and had to pull back. It could not follow.
