 What is the purpose of the metal fabric helmets? probing the brain which has also recorded his language and speak for Loy read thoughts
A scream of brakes, the splash into icy waters, a long descent into alkaline depths ... Movement was slower now, as he began to sink, trapped inside his wrecked car. The edges of that almost bottomless pool were caked with a rim of white—for the water, on which dead birds so often floated, was surcharged with alkali. The welt, left by the blow he had received on his forehead, put a thickening mist over his brain, so that he could not think clearly. Presently, when he could no longer hold his breath, bitter liquid was sucked into his lungs. The ripples that had ruffled the surface waters in the Pit, quieted again to glassy smoothness. Lacking qualities identifiable as human, the disturbance was still like the babble of a group of workmen who have discovered something remarkable. The icy breeze tore tiny puffs of dust from grotesque, angling drifts of soil, nearly waterless for eons. A launching catapult for the last space ships built by the gods in exodus, perhaps it was—half a million years ago. Glacial ages, war, decadence, disease, and a final scattering of those ultimate superhumans to newer worlds in other solar systems, had done that. The bell-like muzzle of a strange excavator-apparatus, which seemed to depend on a blast of atoms to clear away rock and soil. Loy Chuk had flown his geological expedition out from the far lowlands to the east, out from the city of Kar-Rah. But his cranium bulged up and forward between shrewd, beady eyes, betraying the slow heritage of time, of survival of the fittest, of evolution. He could think and dream and invent, and the civilization of his kind was already far beyond that of the ancient Twentieth Century. The dry mud that had encased it like an airtight coffin, had by now been chipped away by the tiny investigators; but soiled clothing still clung to it, after perhaps a million years. A mineral saturation that had held time and change in stasis. A perfect preservative for organic tissue, aided probably during most of those passing eras by desert dryness. Not the star-conquering demi-gods, but the ancestral stock that had built the first machines on Earth, and in the early Twenty-first Century, the first interplanetary rockets. A strange accident, happening in a legendary antiquity, had aided them in their quest for knowledge. The chant of triumph ended, while instruments flicked in his tiny hands. The final instrument he used to test the mummy, looked like a miniature stereoscope, with complicated details.
