This latest volume in a series which is indispensable to every student of international relations is quite up to the standard of its predecessors, and its value is only enhanced by the fact that the volumes are becoming more up-to-date. The readers of FOREIGN AFFAIRS need not be told again of the care and impartiality with which these volumes are prepared. Suffice it to call attention to some of the more important subjects dealt with in this particular volume. An admirable account of the abortive Naval Conference at Geneva is followed by a discussion of the questions of German disarmament and the occupied territories. The treatment of Italian foreign policy, both with respect to France and to the Balkans, is very full and illuminating, while the section dealing with the relations of the Soviet Union from 1925 to 1927 is one of the most instructive in the volume. Part III, concerned with China, develops the theme of Bolshevik influence and the dissensions in the Kuomintang, and Part IV (The American Continent) has excellent sections on the problem of foreign interests in Mexico and the crisis in the relations between the Mexican Government and the Catholic Church. The most important agreements and documents are printed in the appendices, and the volume closes with several maps bearing upon the Far Eastern question.
