PREFACE ON my return to East Africa in January, 1905, I determined to pursue my studies in the languages, folk-lore, and customs of those tribes inhabiting our Protectorate that form an offshoot of the Nilotic stock, and to write an account of the Nandi-Lnmbwa group on somewhat similar lines to those followed in my book on the Nasail But little is known of the Nandi aild allied tribes, notwithstanding the fact that me have administered some of their territories for a decade or more, and the following books and papers are, so far as I am aware, all that have been published on the language and customs of these people.
