<passage>:
Company, slamming the drafting board with his hairy fist, "I want results!" Heads lifted over boards. Kalvin Feetch shrunk visibly. "As chief engineer you're not carrying the ball," Piltdon went on savagely. "The Piltdon Can-Opener is trailing the competition. Advertising and Sales are breaking their necks. It's Engineering that's missing the boat!" "But Mr. Piltdon," remonstrated Feetch unsteadily under his employer's can in eight point nine without chimes. Is this what I'm paying you for?" Feetch adjusted his spectacles with shaking hands. "But Mr. Piltdon, want it completely developed, engineered and tooled-up, ready for production. Otherwise, Feetch—" Feetch's body twitched. "But Mr. Piltdon, four months is hardly time enough for development, even with an adequate staff. I've been trying to tell you for years that we're bound to fall behind because we don't have enough personnel to conduct research. Our men can barely keep up with production and maintenance. If you would let me put on a few draftsmen and...." "Excuses," sneered Mr. Piltdon. "Your staff is more than adequate. I will not allow you to throw out my money. Four months, Feetch, no more!" Piltdon trudged out of the room, leaving behind him an oppressive silence. How could you set a time limit on research and development? A designer had to dream at his board, investigate, search, build, test, compare, discard. He had always wanted to devote all his time to research, but thought Feetch. Twenty-five years of close supervision, dead-lines, production headaches, inadequate facilities and assistance. What had happened, to the proud dream he once had, the dream of exploring uncharted engineering regions, of unlimited time to investigate and Ah, well, thought Feetch straightening his thin shoulders, he had managed somehow to design a few good things during his twenty-five What now? He had to hang on to his job. Technical work was scarce. Since the early 1980's the schools had been turning out more technicians than industry could absorb. He was too old to compete in the employment market. He couldn't afford to lose any money. Jenny wasn't well. How to meet this four month dead-line? He would get right on it beginning to wonder if the answer is in the hand mechanical type at all." "Got to be," answered Feetch tiredly. "We must work along classical Twenty-five years of your life you put in with Piltdon, and he'd fire you just like that if you don't do the impossible. The Piltdon Company is built upon your designs and you get handed this deal!" "Well, well," said Feetch. "I drew my pay every week so I suppose I have no complaints. Although," a wistful note crept into his voice "I two in work. Best performance, four point four, but model otherwise unsatisfactory." "Hello," said Feetch as an aproned machinist entered carrying a glistening mechanism. "Here's another model. Let's try it." The answer! It's more than the answer! We can put this right into work and beat the dead-line." learn a lot more." "But Chief, your job." company? As well as anything you may produce in the field within a year after leaving our employ? We have a good thing here, and I don't want you holding it back. We're going into production immediately." Close, thought Feetch, wearily. It had been a man-killing job, and it had been close, but he'd made it. Beat the time limit by a half-day. explanation. Competitors found the patent impossible to circumvent, for any departure from its exact specifications nullified the effect. Piltdon, genial these days with success and acclaim, roared at Feetch: "I'm putting you in for a raise. Yes sir! To reward you for assisting me with my invention I'm raising your pay two hundred dollars a year. That's almost four dollars a week, man." well, that was the way it went. He must find his satisfaction in his work. And it had been interesting lately, the work he had been doing nights at home investigating what had been named the Piltdon Effect. It had been difficult, working alone and buying his own equipment. The expensive. He was a fool, he supposed, to try independent research when so many huge scientific organizations were working on it. But he could no more keep away from it than he could stop eating. All activity was seriously curtailed. bodily injury. Lawsuits were filed against him. He barricaded himself in the plant, surrounded by bodyguards. Livid with fury and apprehension, he screamed at Feetch, "This is your warn you." "You're through, Feetch!" raved Piltdon. "Fired! Get out! But before you go, I want you to know that I've directed the blame where it belongs. I've just released to the press the truth about who created at first, but then monopolize the market. All right, Feetch, I'll give you another chance. You'll turn over all the details to me. The patent on the improvement will naturally be mine. I'll get the credit for rectifying your blunder. Fine, fine. We'll work it out. Hop on production, at once, Feetch." Feetch felt himself sag inwardly. "Mr. Piltdon," he said. "I'm asking only one favor. Let me work full time on research and development, especially on the Piltdon effect. Hire a couple of extra men to help with production. I assure you the company will benefit in the end." "Damn it, no!" roared Piltdon. "How many times must I tell you? You got your job back, didn't you?" The prospect of long years of heavy production schedules, restricted engineering and tight supervision suddenly made Kalvin Feetch feel very tired. Research, he thought. Development. What he had always wanted. Over the years he had waited, thinking that there would be there might not be a later. Somehow he would manage to get along. Perhaps someone would give him a job working in the new field he had day, as predicted by the statisticians, industry would not soon forget the inconvenience and losses caused by the deluge. It was not anxious to hire the man it regarded as responsible for the whole thing. "Feetch," the personnel man would read. "Kalvin Feetch." Then, looking up, "Not the Kalvin Feetch who—" "Yes," Feetch would admit miserably. "I am sorry, but—" inasmuch as we feel your premature application of your discovery to profit-making denotes a lack of scientific responsibility and ethics not desirable in a member of our organization—former employer states the decision was yours entirely. Unfavorable reference—" A total increase of one hundred and twenty-six dollars? Be sensible, Feetch. I know you can't find work anywhere else." "Thanks to you. Mr. Piltdon, I wouldn't work for you if—" "If you won't think of yourself, at least think of your fellow workmen," begged Piltdon, his voice going blurry. "Do you realize that Piltdon Opener will soon be forced to close down, throwing all your former associates out of work? Think of Hanson, Sanchez, Forbes. They have families too. Think of the men in the shop, the girls in the office, the salesmen on the road. All, all unemployed because of you. Think of that, Feetch." Feetch blinked. This had not occurred to him. over, Feetch." Feetch sat, thinking it over. Was it right to let all these people lose grew warmer. He began pacing the floor. How he hated to do it. Think, Think? He'd figured the solution long ago, only he hadn't allowed In the same mood that afternoon he stood in the middle of his Feetch looked up from his desk in the newly constructed Feetch Multi-Dimensional Development Division of the Piltdon Opener Company. "Piltdon, don't bother me about production. Production is your problem." "But Mr. Feetch—" "Get out," said Feetch.
