This lack of professional editing is a pity because the book isvaluable in its own right for its descriptions of missionary life in NorthernRhodesia and also useful for its glimpses of Clement Doke as a missionary(a relatively unknown period of his life which ended in 1921) and as anovice teaching himself Lamba.R.S.R.The Tonga People on the Southern Shore of Lake Kariba By A. K. H. Wein*rich. Gwelo, Mambo Press, 1976, 109 pp., Rh$l,80.This work is essentially an exercise in descriptive ethnography on a limitedscale. The field work on which it is based was conducted by the authorduring the month of June, 1974, and the wealth of material presented onthese pages is yet another attestation of Dr Weinrich's well known abilityfor prodigious output under limiting circumstances, a point remarked on byProfessor Colson in her foreword. The book is a valuable addition to Rho-desian ethnography since published material on the South Bank Tonga issparse and fragmented. Dr Weinrich is incorrect in asserting in her pre-face that 'nothing has so far been published' (p.10) on these peoples; variousarticles have appeared in Nada, the Zambesi Mission Record and the Proceed-ings and Transactions of the Rhodesia Scientific Association, but this workis the most extensive and cohesive collection of data we have to date. Inparticular the volume is of value in presenting us with considerable materialon contemporary aspects of Tonga culture under conditions of re-settlementafter the building of the Kariba Dam forced a move of these people to newareas with consequent environmental changes.Presentation of material is well organized, with chapters provided onhistory, changed ecological conditions, traditional and modern politics, kin-ship, religion and other cultural features. As a preliminary sketch of Tongalife the work gives an over-view not available to us previously. Of particularvalue and contemporary interest is Dr Weinrich's material on Tonga aware-ness of modern national political issues. A fondly held stereotype in Rho-desia of the Tonga is that they represent the archetypical isolated traditionalAfrican, preoccupied with the mundane affairs of wresting a living froma harsh environment and with a political awareness that does not extend be-yond the horizons of the remote areas of Tonga settlement. Dr Weinrichdemonstrates that this is patently not the case; the effects of national andinternational political policies have impinged on Tonga society in variousways which have not escaped the attention and comprehension of the Tongathemselves. Their grasp of the implications of these issues, coupled withtheir pride and sense of ethnic independence, has led to a political assertive-ness and maturity which compares favourably with that of other ethnicallydefined black groups in Rhodesia. Dr Weinrich also makes the interestingpoint that this political maturity has not been dependent on formal educationor technological advance, items in which the Tonga have been relatively dis-advantaged in the Rhodesian context.Unfortunately the value of the work is vitiated at points by inadequatespecification regarding sources, particularly in respect to survey data. Re-ference is made at various points (pp. 56, 64, 99) to sample censuses withBOOK REVIEWS103no indication of the sampling techniques used. This is important since theauthor imputes a representational nature to the results and makes a numberof generalizations which have to be taken with considerable reservation.However, on balance I am glad that this work has been published. It use-fully augments our knowledge of the Tonga; had more caution been exercisedin the handling of the data my approval would have been without reserva-tion.University of RhodesiaM. W.

Collins, 1977,viii, 87 pp., illustrated, Rh$7,00.Last year saw the centenary of the Order of St John in its present formand the Silver Jubilee of the Commandery of Central Africa which wasseparated in 1952 from its parent Priority in Southern Africa under whichthe local St John Ambulance Association and Brigade had operated since1920. The break-up of Federation resulted in the Commandery of CentralAfrica being restricted to Southern Rhodesia and in the setting up of the StJohn Councils to continue the good work in Zambia and Malawi. Politicshave not, however, changed the position of Sir Humphrey Gibbs who isKnight Commander Š that is, the Governor of Southern Rhodesia, byconvention.The compiler has kept the history and description to a minimum inorder to make his story more vivid by the use of illustrations and reportsfrom newspapers of the time. It is to be hoped that this story of good willattract more people to support the Association and Brigade in these difficulttimes.R.S.R.
