Wrecked alone on an unknown shore, Waldo Emerson Smith-Jones, scion of an effetely intellectual Boston family, finds himself terrified and physically unfit. A series of adventures leads him to the cave of a beautiful girl, Nadara, who is as primitive and uneducated as she is strong and self-reliant. NOTE: This book contains the original magazine texts for the two stories: The Cave Girl and The Cave Man.
