An expert on naval history reports this as a clear and scholarly history of the cyclical rises and falls of American sea power, with emphasis placed on the causes controlling the evolution from sailing vessels to superdreadnoughts. Brief summary of the country's naval development; a compromise verdict on the 150 year old debate between big navy and small navy endorsing ""a navy adequate to guard the New World and to make any threat to our empire a risk no country could assume""; quite evident rejection of the lessons of the Mahan analysis. The book is essentially sound, sensible and well balanced and eminently readable throughout. In presenting recent experiments in treaty limitations of naval armaments and the current spur to construction, he, has the advantage of timeliness over the published first volume of the Sprouts' excellent Rise of American Sea Power. Fully documented, a valuable contribution to Naval literature, wit the one shortcoming the apparent remoteness of his library's stackroom from the nearest flagship bridge.
