One by one, forty of the Earth's greatest scientists vanished into that world beyond the universe—until one man, doomed by its fatal rays, carried humanity's last hope back the blinding, twisted corridors that led through— The DEATH CRYSTAL By GEORGE O.

It was the horror of the serpent, or of the Gorgon's head. They were fascinated; in that moment not one of them could have torn his gaze away. All work ceased. The noises in the concrete-walled room died until the whish of breathing and the thumping of hearts could be heard. Then panic caught them, and fought against training. Panic cried, Run! and training said, Remove yourself quickly. With the motion-saving efficiency of the emergency drill, each man turned from his position and walked rapidly towards whichever exit was nearest. Actually, they could not outrun the danger any more than one can duck a rifle bullet or outrace the atomic bomb. But they went, five men and one woman, out through the zigzag corridors towards a mirage of safety. One man remained. Dave Crandall stepped forward and picked the crystal from its place in the evaporation dish. He turned, doused hand and crystal under a faucet, and then dropped the crystal on an anvil. He hit it with a heavy hammer. Anvil and crystal rang musically, and the crystal rebounded and flew through the air unharmed. Cursing under his breath, Dave Crandall darted, picked it up again, and looked around wildly. There were vats of acid handy; an electronic furnace glowed white-hot through its slit; a tunnel gaped unexcitingly but in its depths were the invisible radiations of the atomic pile. None of these would work soon enough. Dave turned to the desk. He flipped open the end of the pneumatic message tube and popped the crystal into the chamber. There was the whroooom! of pumped air, a few
