The Swamp Was Upside Down is a science fiction novella by Murray Leinster, first published in 1956 in 'Astounding Science Fiction.' Set on the planet Canna III, the story follows Senior Officer Hardwick and Lieutenant Barnes as they confront environmental crises caused by irresponsible agricultural practices that have destabilized the island's soil. The narrative explores themes of authority, ingenuity, and the consequences of human interference in nature, culminating in a race against time to prevent catastrophic landslides and explosions due to leaking ship-fuel.
