The vile creatures were close: Jerry could see their fierce heads dripping with blood. He reached for his pistol, knew instantly it was useless against these mammoth brutes, and joined Winslow, who was straining desperately at another great rock. It toppled and fell. Jerry hurled himself at a heap of smaller boulders and sent them crashing as fast as he could seize them and throw. * * * * * One quick look behind him showed still the impossible vision he had seen. And now there were figures--a mob of them--figures that threw off their wrappings of vegetation as they ran, cast to the ground the toadstool disguises that they held. They were caricatures of men that were swarming up the hill.... He swung again in one last hopeless stand against the first horrible enemy. The two men poured a torrent of stones down the slope; they were useless, except for their delaying the advance. The beasts leaped and dodged. They were close when the rock-rain increased to a deluge. Jerry was fighting in a red haze through which he saw dimly. He was aware of the hailstorm of boulders that were thick in the air. He saw vaguely the white faces and copper-clad bodies of strange men leaping about him, and he heard the wild bedlam of their shrieks as they joined in the mad battle against the common enemy. The beasts were swept off in a landslide of loose rock--all but one. Above them, on a high point of stone, it was crouching to spring. A wild human figure, its flesh white as chalk, leaped forward with a tangle of fibers. The tangle was thrown as the brute was in air. A net spread and wrapped around the monster. It fell, clawing and tearing, to roll helplessly down the slope. The battle was won. Jerry swayed drunkenly on his feet. About him the mountains seemed whirling, where unreal figures of men with dead white skin and shining copper armor danced dizzily. He met for an instant the look from Winslow's dazed eyes. Out of the past a picture flashed clearly: Winslow--this same Winslow--arguing that the moon might hold mysteries still. He laughed thickly. "And I said it was all known," he muttered through slack lips. "Nothing on the moon that wasn't known...." He was still laughing in a wild inebriation as a net settled close to entangle his swaying figure and bear him helpless to the ground. He saw Winslow similarly bound, saw him lifted to the shoulders of shouting, yelling men, whose stupid, pasty faces were wide-eyed with excitement. He, too, was raised into the air.... They were being carried toward the crater's mouth.... * * * * * A fight for life in thin air does not make for clear thinking. Jerry Foster knew only that a nightmare world was whirling about him; that beneath him powerful shoulders supported, while the one who carried him leaped at racing speed down the slope.
