Tarzan in his wanderings in unknown Africa comes to a great thorn forest, impenetrable, according to native belief, and shunned because it is the abode of evil spirits. The undaunted Tarzan, however, finds a way through the awful thorns and emerges into an amazingly fertile country. Here he discovers a race of pigmies about eighteen inches high, fairly advanced in civilization and living in vast community houses resembling ant hills. Tarzan see many curious things, and has numerous startling adventures. From ERBville Press.
