This paper is a slightly revised version of a lecture given on 16th August 1975 at the Somali Institute of Development Administration and Management in Mogadishu. The text of the lecture was published in the same month, as a booklet, by the Academy of Somali Culture in Mogadishu, but in a limited number of copies only. It was also presented, orally and in absentia, at the Symposium held on 19th September 1975 at the Annual General Meeting of the African Studies Association of the United Kingdom.
In order to make the information which it contains accessible to a wider public I now offer it to readers of African Research and Documentation.
