Author Description

Excerpt from Marine Engines; Problems, Notes and Sketches: Additional to the Text-Book Used in the Instruction of Naval Cadets of the Second Class, United States Naval Academy The following Problems, Notes and Sketches have been prepared for use in the instruction of the naval cadets of the second class. The arrangement of the subjects treated follows that of the text-book on Marine Engines, in order that the books may be used conjointly. The book is an outcome of a quantity of type-written matter which was prepared originally by Passed Assistant Engineers W. F. Worthington and John L. Gow, U. S. N., while attached to this school. With this has been incorporated much new matter, especial care having been taken to explain the uses and action of boiler and engine attachments and patented devices met with on board ship, in order that the cadet may obtain a thorough knowledge of the details of marine machinery, as well as a general understanding of the subject. The "Arrangement of Machinery," and many of the devices mentioned, are those of the U. S. S. Bancroft, one of the Naval Academy practice ships, although not confined exclusively to that vessel. Our thanks are due to Engineer-in-Chief Geo. W. Melville, U. S. N., Chief of the Bureau of Steam Engineering.
