When Myles Cabot, inventor of radio transmission of matter, found himself alone on an unknown continent of the planet Venus, he realized that getting back to his old headquarters and his loved ones presented some impossible problems. He'd have to settle a war between primitive natives and an unholy alliance of monsters, dinosaurs, and giant insects. He'd have to build an electronic device from raw rocks and untapped resources. And if he succeeded in all that, he'd still have to find his way home. A vintage novel of science and adventure from the Golden Years of Science Fiction!
