Tarzan and the City of Gold — Edgar Rice Burroughs

When Tarzan rescued a strange white savage in the remotest part of unexplored Africa it was to learn for the first time of two contending wonder cities hidden there.

One was the City of Gold, whose people raised and worshipped lions. The other the City of Ivory, whose gods were elephants.

Caught between these two warring barbarisms, it was to take every bit of Tarzan's lion-lore, elephant skill, and jungle talent to win over the incredible odds.
