Note: Originally published as a six-part serial in Blue Book, starting in March 1937.

Synopsis: In the far north, warmed by volcanic fires, lies the undiscovered homeland of the people who became the North American Indians. Nato'wa is what they called their land and within its forested and lush domain remains the last great unspoiled wilderness on Earth - a land of green jungles, of wild beasts, and primitive men. Kioga the Snow Hawk, son of wrecked explorers, was raised by the natives as one of their own. His stories, classics of lost-race adventure equal to Haggard and Burroughs, have long been treasured by sf readers. In this rediscovered work, DAW Books brings you more of Kioga's wonderful exploits in that lost world. (from the back cover of the DAW Books first edition)
