 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? Four months, Feetch! Otherwise, Feetch—" Feetch's body twitched. 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. "Spinach, I think," said Feetch. Several days later, however, Piltdon himself charged into the drawing room and slapped Feetch heartily on the back, causing him to break a pencil point. "Feetch!" roared Piltdon. "Mr. Piltdon—" said Feetch shakily.
