The Federal Systems of the United States and the British
Empire. By Arthur P. Poley, B.A. (Sir Isaac Pitman and -Sons. 12s. 6d. net.)--This book, which traces the history and compares the development of the Constitutions of the United States, Canada, the Commonwealth of Australia, and the Union of South Africa, is carefully compiled and should Trove a valuable work of reference, though one could wish that the author had devoted more space to generalization. In his last chapter he suggests that a closer union of the Empire might be secured by the creation of an Advisory Imperial Cabinet, including all the members of the Cabinets of the Empire, acting through the Ministers for External Affairs. One would have liked to see this idea elaborated, though we cannot help suspecting that any attempt at a practical applica- tion of it would demonstrate its impracticability.
