Professor Ichihashi's book belongs with the important original treatments of the Washington Conference. As Secretary and Interpreter to Viscount Kato he was in a position to follow closely the course of the negotiations and to learn to understand the conflicting viewpoints. He draws a clear distinction between the work of the Conference in regard to the limitation of naval armaments and that concerned with the problems of China and the Pacific. Each phase of the discussions is taken up in detail and the obstacles in the way of agreement are discussed dispassionately. The later part of the book is devoted to a survey of the developments of the Conference and the agreements, thus making possible an evaluation of the work of 1921. Altogether this is a useful and thoroughly interesting book.
