TWENTY-FOUR rams of the West African Dwarf X Yankasa crosses, 6 to 7 months old, ranging in liveweight from 11 to 14 kg were randomly alloted to maize, sweet potato and cassava based rations. These rations constituted the concentrates which were fed as supplement to Cynodon nlemfuensis. Three rams from each treatment were slaughtered at the end of 30 day and another set of three rams each were slaughtered on the dietary treatments and other nine, 140 day later Replacement of the conventional maize grains by dried milled cassava and potato tubers in sheep diet did not dentess the growth rate, dressing-out percentages, major cuts, quality of the organs. and the general performances of the animals. Sweet potato based diet however improved the feed per gain estimate, the fats and protein content of the carcass. The highest proportion of lean ment was produced by the animals fed cassava based diet.

The West African anansesem (short stories about the spider, Ananse) are considered ageless classics in many countries and continents; and their appeal has remained constant over generations. Although anansesem is a word taken from the Ashanti tribe in Ghana, the stories have impacted in the whole of West Africa and can also still be heard in Caribbean households. The appeal of anansesem is quite personal—but analysts have isolated varying characteristics; and these include linguistic, structural, characterisation, themes, plot, and a certain ambience. One quality of anansesem, which has enabled them to still command extensive audience, is their ability to reflect ‘‘a conversation’’ in line with Grice’s maxims. Grice is a theorist in pragmatics, who outlined the salient features or maxims of verbal interactions that should govern a conversation. These four maxims are—quantity (make your conversation as informative as is required), quality (do not say what you believe to be untrue), relation (be relevant) and manner (avoid obscurity of expressions). The aim of this article is to analyse selected ananse stories as examples of conversation pieces in accordance with these Gricean maxims. The analyses was based on the assumption that these short stories exhibit features different from the attributes of traditional short stories, and that this difference is the essence of anansesem’s timeless appeal. The results illustrated that despite the brevity of these stories, a certain ambience, created by their conversation-like writing style, ensures their ability to create sustaining humour, while being politically, socially, and economically relevant ‘‘conversations’’ for today.

SUMMARYThe yield, variability and quality of 16 sweet potato cultivars, harvested after 21 weeks growth, were evaluated in sub-tropical Australia. The coloured-flesh cultivars L8-92, Centennial, HAC-Pink, Copperskin Goldrush and Nemagold produced yields of marketable storage roots in excess of 19,000 kg ha−1, which was three to four times the yield of the local commercial cultivar, White Maltese. The high variability in mean yield per plant of all cultivars offers scope for selection within cultivars. Those with a deep orange flesh and high soluble solids content, i.e. L8-92, Copperskin Goldrush and Centennial, were preferred by members of a taste panel. A high carotene cultivar L8-92 has the greatest commercial potential because it produced the highest yield of marketable storage roots and had the highest taste panel rating for eating quality of stored roots.

My main concern in this article is with statistics relating to such basic matters as the sizes of farm-holdings, the output and yield of crops, household income and expenditure, occupational statistics, cattle ownership, the sizes of villages, etc.—though I shall also range more widely. While the distinct and professional field of demographic statistics is necessarily outside my scope, I shall criticize some features of the Karnataka population census.Although since 1953 most of my fieldwork has been undertaken in the West African countryside, I am obliged to take most of my examples of bad statistics from south India, since West African statistics, which were never abundant, are now scantier than ever. Throughout my discussion I take it for granted that the lack of reliable statistics gravely impairs our understanding of the working of tropical rural economies.

SummaryThe Muturu, a trypanotolerant cattle breed is probably one of the least known breed of cattle in West Africa. Little has been published on its distribution, management, morphological characteristics or biological performance.Early reports showed that the Muturu cattle were once widely distributed across the continent from Liberia, across the West African subregion, to Ethiopia. However, due to expansion of the Zebu population and rapid urbanization, the small bodied animal came under pressure and was found surviving in pockets of the savannahs and in the humid forest zones where it had the comparative advantage of trypanotolerance. The survival of the cattle in the humid and forest zones of Nigeria stems from the fact that the animal is still sacred in so many communities and its milk is widely used for medicinal purposes. In some states of Nigeria, the semi-feral Muturu are not tended but hunted when required for sacrifice.From a population size of 0.4 million heads in 1960, Akinwunmi and Ikpi, (1985) reported a decline in the population of the breed to 50–80 thousand in the late 1980s in Nigeria although RIMS (1992), reported a population growth to 115 172 heads. With limited data bank information on their adaptation and productivity, possible identification of genes that confer resistance to or tolerance of environmental stress in these animals will be of global significance.
