Rh The Ovambo have some slight knowledge of metallurgy. Though no mineral is indigenous to their own country, they procure copper and iron ore in abundance from their neighbors, which they smelt in fire-proof crucibles. The bellows employed in heating the iron are very indifferent, and stones serve as substitutes for hammer and anvil. Yet, rude as these implements are, they manage not only to manufacture their own ornaments and farming tools, but almost all the iron-ware used in barter.
