context: 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. 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. 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 perfect preservative for organic tissue, aided probably during most of those passing eras by desert dryness. A strange accident, happening in a legendary antiquity, had aided them in their quest for knowledge. The final instrument he used to test the mummy, looked like a miniature stereoscope, with complicated details. On the tiny screen within, through the agency of focused X-rays, he saw magnified images of the internal organs of this ancient human corpse. In twittering, chattering sounds, he communicated his further knowledge to his henchmen. Medical and biological sciences were far advanced among Loy Chuk's kind. It might move, speak, remember its past! With infinite care it was crated in a metal case, and hauled into the flying machine. Flashing flame, the latter arose, bearing the entire hundred members of the expedition.
