 What didn't Feetch discover?
[Transcriber's Note: This etext was produced from Worlds of If Science Fiction, August 1958. "Feetch!" grated Ogden Piltdon, president of the Piltdon Opener Company, slamming the drafting board with his hairy fist, "I want results!" "But Mr. Piltdon," remonstrated Feetch unsteadily under his employer's glare, "don't you remember? "Dignity," pronounced Piltdon, "is for museums. Four months, Feetch! I want it completely developed, engineered and tooled-up, ready for production. Otherwise, Feetch—" Feetch's body twitched. Four months, Feetch, no more!" A designer had to dream at his board, investigate, search, build, test, compare, discard. What had happened, to the proud dream he once had, the dream of exploring uncharted engineering regions, of unlimited time to investigate and develop? Ah, well, thought Feetch straightening his thin shoulders, he had managed somehow to design a few good things during his twenty-five years with Piltdon. "Got to be," answered Feetch tiredly. They began testing, Hanson operating the openers and Feetch clocking. "Four point four," announced Feetch after the last test. "Well, well," said Feetch. Piltdon is a household word, but who has heard of Feetch? "Hello," said Feetch as an aproned machinist entered carrying a glistening mechanism. "Yes," said Feetch. "Spinach, I think," said Feetch.
