When Jesse asks why he doesn't have brothers and sisters, Daddy answers, ``You do,'' and tells Jesse's favorite story, beginning with the reminder that many of his eponymous siblings live in cities and have professions like those of people Jesse knows. Dad goes on to review 21 tribes and the work or art for which they are known—e.g., the Guere for their masks, the Falasha for pottery, and many groups of farmers, some of whom grow ``things I never heard of...like sorghum and millet,'' says Jesse. But he has heard of them, and knows them well because his dad has made a happy game of rehearsing their names with him. Kroll (Masai and I, 1992) again shares a good deal of information in a story that successfully conveys her enthusiasm for her subject. French debuts with freely rendered watercolors that nicely evoke both the African scene and the camaraderie between Jesse and his father. A fine basic introduction to African culture and tribal names. Pronunciation guide; note; map locating countries and tribes. (Picture book. 4-8)
