Introduction The material for this study was collected during the first two months of 1954, while camping in a Cokwe village about 50 miles north-east of Vila Luso in the administrative area of Camanongue, County and District of Moxico, Province of Bié, Angola. My chief informant was Sr. Francisco Casueka, aged 44, a Cokwe- and Portuguese-speaking African from the printing press at Boma Mission near Vila Luso. He was the ablest assistant I had among many good informants during my stay in Angola.
