This book, which was first published in 1952, is a collection of letters written to describe jungle journeys while pioneering among a hitherto unreached Indian tribe in the jungles of South America.
The letters were written by the author, Sophie Muller, a missionary for the New Tribes Mission headquartered in Wisconsin, who labored tirelessly among primitive Indian tribes in the interior jungles of Columbia in South America during the early to mid-1900's.
Beyond Civilization tells of her story and experiences.
