An adventure story for young adults, set in Africa. The young hero sets out from New York aboard ship and after an eventful journey arrives in Africa. He sets out to explore, and arrives at the village of King Mombo. Superstitions and bad luck dog his visit, but after meeting the local medicine man he sets out on further adventures and discovers unusual animals. Du Chaillu is credited with being the first European to document the existence of gorillas, and they feature prominently in this tale. Note: there are references to slavery, which some may find offensive; but the work reflects views of the time and it is policy not to censor.
