 How does Loy Chuk communicate with Ned?
A scream of brakes, the splash into icy waters, a long descent into alkaline depths ... His car hit the white-painted wooden rail sideways, crashed through, tumbled down a steep slope, struck a huge boulder, bounced up a little, and arced outward, falling as gracefully as a swan-diver toward the inky waters of the Pit, fifty feet beneath.... Ned Vince was still dimly conscious when that black, quiet pool geysered around him in a mighty splash. 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 ripples that had ruffled the surface waters in the Pit, quieted again to glassy smoothness. Time, the Brother of Death, and the Father of Change, seemed to wait.... 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. He could think and dream and invent, and the civilization of his kind was already far beyond that of the ancient Twentieth Century. Loy Chuk and his fellow workers were gathered, tense and gleeful, around the things their digging had exposed to the daylight.
