Many of the early tribes of Africa had knowledge of metal-working, although some have lost or neglected to practice it. Other African Curios. Some metal curios were included in the trophies brought to this country at the time of the Ashanti Expedition, among the rare regal metal-work being an old brass vase, with repoussé decorations and a copper dragon handle. It was discovered behind the house of King Prempeh's aunt, who had been acting as Regent. Another curio discovered in the same district was a brass box containing gold dust. Bells, too, have been brought from Ashanti; one in the British Museum is the executioner's bell, which was rang prior to an execution. There are many bronzes from Southern Nigeria, especially some curious ornaments worn by the women. Some of these are veritable antiques and were found buried; many are finely patinated and heavy. Some of the bangles are beautifully formed and highly decorated with inlaid enamels. Some very interesting brass castings come from Lagos, not at all unlike the Benin modelling, except that they are in brass instead of pure copper. They include figures of natives, some on horseback, others in the act of shooting with guns. There are brass staves of office carried as symbols of authority by the messengers of the Oshogbo, a native secret society; and there are spoons, knives and other domestic sundries, as well as armlets and anklets of copper and brass. From north-east Central Africa we get a little metal-work, some of the head-dress ornaments being enriched with circular brass plates, on which are repoussé decorations. Among the curios from this district in the British Museum are several exceptional pieces, one being a head-dress or helmet of brass with circular brass ornaments. The knives used in ceremonials are often very handsome. There is a fine executioner's knife from north-east Central Africa, with brass studs all over the wood handle. Another chief's knife, which came from near the Stanley Falls, is decorated with strips of copper and brass. The metal castings from Central Sudan, representing ostriches, giraffes, and camels, are cleverly done, and with bangles and anklets make up an interesting group.
