Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Probably one of the most important chapters is that which treats of the elementary theory and construction of the propeller. This subject is treated as fully as possible in a book of this scope and many useful hints are given regarding the selection of a propeller. The design of a propeller is a highly technical subject, but with the data given, the amateur has at least a guide by which to work.
