Project Gutenberg 2009-06-17 Public domain in the USA. 170 Brown, Fredric 1906 1972 Brown, Fred Schroeder, Ernest Keep Out Produced from Amazing Stories March 1954. Produced by Greg Weeks, Stephen Blundell and the Online Distributed Proofreading Team at http://www.pgdp.net "Keep Out" by Fredric Brown is a science fiction short story written in the early 1950s. The narrative explores the themes of adaptation, identity, and rebellion, set against the backdrop of a future where humanity attempts to colonize Mars. The central topic revolves around the genetic modifications made to a group of children who are being raised in controlled conditions to become the first Martians. The story unfolds through the perspective of one of the children, who has been cleverly conditioned to adapt to the harsh Martian environment through the use of a miraculous substance called daptine. As they approach maturity, the children are told about their unique upbringing and their pivotal role as the first inhabitants of Mars. However, a dark twist reveals that the children harbor deep-seated resentment towards their Earthly teachers and caretakers, whom they deem inferior. As they prepare to take their first steps into the Martian world, they plan a violent uprising to eliminate the adults who raised them, asserting their claim to the new planet. This leads to a chilling conclusion as the children reject their Earthly origins, eagerly embracing their new identity as Martians. (This is an automatically generated summary.)
