The documentary material prepared by the League of Red Cross Societies for World Red Cross Day in 1966, includes an interesting study by Mr. Kai J. Warras, Executive Chairman of the League Development Programme Advisory Panel and Secretary–General of the Finnish Red Cross. In this monograph the author examines one of the most important problems facing the Red Cross today, at a time when this movement is expanding considerably and when newly created Societies are carrying out their tasks under conditions which are often difficult. We believe the publication of Mr. Warras' study is a useful means of drawing attention to problems which can only be solved by schemes such as the large scale development programme to be carried out under our universal emblem.
