Like most of the world, Dave had regarded the big man who was his uncle with something close to worship. He'd jumped at the chance to work under Uncle David. And he'd been a fool. He'd been doing all right in Chicago. Repairing computers didn't pay a fortune, but it was a good living, and he was good at it. And there was Bertha--maybe not a movie doll, but a sort of pretty girl who was also a darned good cook. For a man of thirty who'd always been a scrawny, shy runt like the one in the "before" pictures, he'd been doing all right. Then came the letter from his uncle, offering him triple salary as a maintenance man on the computers used for the construction job. There was nothing said about romance and beauteous Indian maids, but Dave filled that in himself. He would need the money when he and Bertha got married, too, and all that healthy outdoor living was just what the doctor would have ordered. The Indian maids, of course, turned out to be a few fat old squaws who knew all about white men. The outdoor living developed into five months of rain, hail, sleet, blizzard, fog and constant freezing in tractors while breathing the healthy fumes of diesels. Uncle David turned out to be a construction genius, all right, but his interest in Dave seemed to lie in the fact that he was tired of being Simon Legree to strangers and wanted to take it out on one of his own family. And the easy job turned into hell when the regular computer-man couldn't take any more and quit, leaving Dave to do everything, including making the field tests to gain the needed data. Now Bertha was writing frantic letters, telling him how much he'd better come back and marry her immediately. And Uncle David thought it was a joke! Dave paid no attention to where his feet were leading him, only vaguely aware that he was heading down a gully below the current construction job. He heard the tractors and bulldozers moving along the narrow cliff above him, but he was used to the sound. He heard frantic yelling from above, too, but paid no attention to it; in any Hanson construction program, somebody was always yelling about something that had to be done day before yesterday. It wasn't until he finally became aware of his own name being shouted that he looked up. Then he froze in horror. The bulldozer was teetering at the edge of the cliff as he saw it, right above him. And the cliff was crumbling from under it, while the tread spun idiotically out of control. As Dave's eyes took in the whole situation, the cliff crumbled completely, and the dozer came lunging over the edge, plunging straight for him. His shout was drowned in the roar of the motor. He tried to force his legs to jump, but they were frozen in terror. The heavy mass came straight for him, its treads churning like great teeth reaching for him. Then it hit, squarely on top of him. Something ripped and splattered and blacked out in an unbearable welter of agony.
