When Super-Apes Plot by Wilder Anthony is about a tribe of Batu natives and American travelers Doctor Dumont, Thomas Hardin, and their other two traveler friends. Excerpt: “DAWN in the Borneo jungle! The rising sun shone down upon what may have been the strangest sight seen in that vast wilderness since the beginning of time. A dark and gloomy lake, some ten miles wide, lay shimmering beneath gray mists which rose like clouds of steam from its glassy surface; here and there this surface was broken by waterspouts which constantly boiled up and fell back again as though heated from the depths' beneath by gigantic fires.”
