toughness and closeness of texture. When dried and polished it resembles
horn. Unlike the Indian species of rhinoceros, the black variety of
Africa is free from folds, and the hide fits smoothly on the body like

Johann, and penetrated still deeper into the country of the Bas-e.

Our course lay, as usual, along the banks of the river. We decided to
encamp at a spot known to the Arabs as Deladilla. This was the forest
