World of Mockery By SAM MOSKOWITZ When John Hall walked on Ganymede, a thousand weird beings walked with him. He was one man on a sphere of mocking, mad creatures--one voice in a world of shrieking echoes. [Transcriber's Note: This etext was produced from Planet Stories Summer 1941.

Painstakingly he disengaged himself from the hopeless wreckage of the control room. He staggered free, his lungs pumping with terrific effort to draw enough oxygen from the thin, bitterly cold air of Ganymede--that had rushed in when his helmet had been shocked open. Feeling unusually light he walked over to an enormous tear in the side of his space-cruiser. A bleak scene met his eyes. Short, grotesquely hewn hills and crags. Rocky pitted plains. And a bitter, wild wind blew constantly, streaming his long hair into disarray. He cursed through tight lips. Fate! He had been on his way to Vesta, largest city of Jupiter, when his fuel had given out. He had forgotten to check it, and here he was. Despondently he kicked a small rock in front of him. It rose unhindered by the feeble gravitation fully thirty feet in the air. Suddenly there were a dozen scuffing sounds, and a dozen stones winged themselves painstakingly through the air and began to descend in slow motion. Surprise struck, he gazed furtively about him. Momentarily his heart seemed caught in some terrible vise.
