mob moved slowly into the center of town, clinging to the sides of an antiquated dump truck. "Gold! Gold! Gold!" It was like a chant shouted with ecstatic antiphony. The dump truck stopped and Elvin saw the unbelievable—gleaming heaps of gold shoveled like gravel into the back of the vehicle. The driver stood on the running board, weaving drunkenly. "The whole damn' desert," he shouted. "All of it, as far as I could see—all pure gold!" He took a shovel and scattered the nuggets and dust among the throng. "Take all you like.

But there was no time for real hostilities to develop, for the castle vanished and a 19th century factory took its place. The factory survived less than thirty seconds, before it gave way to the bank and row of stores which had originally stood on the site. For some reason the crowd began to cheer, as they would a victorious football team. But the tumult died quickly, for the buildings were covered with a slime of jungle
