The whole region is a land of transition between the two races, where the struggle for supremacy was scarcely arrested by the temporary intervention of German administrators. Though annexed by Germany in 1884, fighting continued for ten years longer, and, breaking out again in 1903, was not subdued until 1908, after the loss to Germany of 5000 lives and L15,000,000, while 20,000 to 30,000 of the Herero are estimated to have perished. Under the rule of the Union of South Africa this maltreatment of the natives will never occur again. Clearness would be gained by substituting for Hill Damaras the expression _Ova-Zorotu_, or "Hillmen," as they are called by their neighbours of the plains, who should of course be called Hereros to the absolute exclusion of the expression "Cattle Damaras." These Hereros show a singular dislike for salt; the peculiarity, however, can scarcely be racial, as it is shared in also by their cattle, and may be due to the heavy vapours, perhaps slightly charged with saline particles, which hang so frequently over the coastlands. No very sharp ethnical line can be drawn between Portuguese West Africa and the contiguous portion of the Belgian Congo south and west of the main stream. In the coastlands between the Cunene and the Congo estuary a few groups, such as the historical _Eshi-Kongo_[270] and the _Kabindas_, have developed some marked characteristics under European influences, just as have the cannibal _Ma-Nyema_ of the Upper Congo through association with the Nubian-Arab slave-raiders. But with the exception of the _Ba-Shilange_, the _Ba-Lolo_ and one or two others, much the same physical and mental traits are everywhere presented by the numerous Bantu populations within the great bend of the Congo.
