An assiduous collector, Sir Roy added to his hundreds of files of personal correspondence, complete sets of Federal and British minutes, memoranda and dispatches. Skilfully blending these with abundant other material (British, Federal and territorial Hansards, newspaper and public reports, biographies, other private collections and interview with the chief protagonists), Dr J.R.T. Wood has written incisively on the tortuous efforts, since 1894, to unify the three territories of Northern and Southern Rhodesia and Nyasaland. The architects of this last British Imperial experiment in Africa had conflicting motives. Britain wished to ease her Colonial burden an to provide a liberal counter to Afrikaner extremism. The Rhodesian and Nyasaland Europeans sought freedom from British control and to secure self-government on their own terms. Both sides ignored African opinion.
