His last thoughts were those of a drowning man. The machine-shop he and his dad had had in Harwich. Betty Moore, with the smiling Irish eyes--like in the song. Betty and he had planned to go to the State University this Fall. They'd planned to be married sometime.... Goodbye, Betty ... The ripples that had ruffled the surface waters in the Pit, quieted again to glassy smoothness. The eternal stars shone calmly. The geologic Dakota hills, which might have seen the dinosaurs, still bulked along the highway. Time, the Brother of Death, and the Father of Change, seemed to wait.... * * * * * "Kaalleee! Tik!... Tik, tik, tik!... Kaalleee!..." The excited cry, which no human throat could quite have duplicated accurately, arose thinly from the depths of a powder-dry gulch, water-scarred from an inconceivable antiquity. The noon-day Sun was red and huge. The air was tenuous, dehydrated, chill. "Kaalleee!... Tik, tik, tik!..." At first there was only one voice uttering those weird, triumphant sounds. Then other vocal organs took up that trilling wail, and those short, sharp chuckles of eagerness. Other questioning, wondering notes mixed with the cadence. Lacking qualities identifiable as human, the disturbance was still like the babble of a group of workmen who have discovered something remarkable. The desolate expanse around the gulch, was all but without motion. The icy breeze tore tiny puffs of dust from grotesque, angling drifts of soil, nearly waterless for eons. Patches of drab lichen grew here and there on the up-jutting rocks, but in the desert itself, no other life was visible. Even the hills had sagged away, flattened by incalculable ages of erosion. * * * * * At a mile distance, a crumbling heap of rubble arose. Once it had been a building. A gigantic, jagged mass of detritus slanted upward from its crest--red debris that had once been steel. A launching catapult for the last space ships built by the gods in exodus, perhaps it was--half a million years ago. Man was gone from the Earth. Glacial ages, war, decadence, disease, and a final scattering of those ultimate superhumans to newer worlds in other solar systems, had done that. "Kaalleee!... Tik, tik, tik!..." The sounds were not human. They were more like the chatter and wail of small desert animals. But there was a seeming paradox here in the depths of that gulch, too. The glint of metal, sharp and burnished. The flat, streamlined bulk of a flying machine, shiny and new. The bell-like muzzle of a strange excavator-apparatus, which seemed to depend on a blast of atoms to clear away rock and soil. Thus the gulch had been cleared of the accumulated rubbish of antiquity. Man, it seemed, had a successor, as ruler of the Earth. Loy Chuk had flown his geological expedition out from the far lowlands to the east, out from the city of Kar-Rah. And he was very happy now--flushed with a vast and unlooked-for success.
