Context
Pastor Joseph Ellis spent ten years in the Congo Republic, from 1963 to 1973, as a missionary with the United World Mission. Ellis worked at Impfondo and lived at Dongou, where the black waters of the Motaba River meet the white water of the Ubangi, in the Likouala Department. This is the land of Mokele-mbembe and Emela-ntouka. It is also home to a reported animal called the Nguma-monene, a name translated as "large python".
