IN this revision the authors have attempted to amplify some of the features which, in the earlier edition, were little more than touched upon. Chapters on the Overfall and Arched types of masonry dams have been added, together with cross-sections of a selected series of masonry dams chronologically arranged. The last are for the pur pose of comparison and showing the development of the masonry dam from the time of the massive Spanish type to the present.
The design of low and medium-sized as well as that of high-masonry dams, may be prosecuted according to the theory and methods in this work, as general expressions have been written wherever possible. It was considered best to indicate this in the title while the original page captions remain the same.
