Newsletter of the Southern Association of Africanists 3, 3(1975) 25-28. 5. There are book-length biographies written for British children that are not available in the U.S. such as David Killingray, Samori Toure: Warrior King (Amersham: Hutton, 1973), as well as ones written for African children in the series mentioned in the third footnote. 6. Cohen does mention "wizards, witch doctors and witch finders" whose independent power Chaka tried to reduce. However, this is more in the context of calling attention to unusual influences among the Zulu political organization. Both Cohen and Keating used what were "standard" sources on the Zulu, such as E. A. Ritter, before the recent trend in African historiography to utilize oral traditions and view political history from an African perspective. 7. A more detailed and African-oriented book on this topic written for British children is David Killingray, A Plague of Europeans (Hamondsworth: Penguin, 1973). 8. This book was originally written for British children and published in London by Hart Davis in the Young Historian series. Many books on Africa published in the U.S. are reissues of British books. 9.
