The Dean of Science Fiction, Murray Leinster, offers you boundless adventure on a barbaric world lost in the deeps of space, crowded with giant menacing life-forms. Think you've seen about everything now that THE THING has reached the screen? Wait'll you read about "The Thing from-'Outside'" as described by George Allan England of Darkness and Dawn fame. "The Diamond Lens" and "The Crystal Egg" are two similar yet diverse themes by two master storytellers- Fitz-James O'Brien and H. G. Wells. Microscopia and Mars. And, for an encore, Wells returns with "The Empire of the Ants." Veteran pioneer Edmond Hamilton told a tale-"The Metal Giants"-that readers from 56 years ago have never forgotten. Nor will you. You'll travel "Beyond the Pole" to adventures unimaginable with A. Hyatt Verrill as your guide. This is the seminal story that first sparked the Sense of Wonder of Mr. Science Fiction. And Curt "Donovan's Brain" Siod-mak will thrill you with "The Eggs from Lake Tanganyika."
