Opening ParagraphUntil quite recently little was known about the output of traditional ironworking centres in sub-Saharan Africa. Although some estimates were made for a few centres by colonial administrators and agents, the reliability of many of these figures is doubtful (see Pole, 1983; de Barros, 1985: 270–71) and some of the more interesting data still lie buried in colonial archives. The first serious scholarly attempt at quantification of precolonial African iron production was made by Warnier and Fowler (1979) who investigated iron production in the Iron Belt of the Cameroon grasslands, particularly that associated with the nineteenthcentury Babungo chiefdom. Since then Goucher (1981, 1984) and Pole (1983), and to a lesser extent Haaland (1980), have provided some important quantitative data regarding both large and small iron working centres in West Africa.
