TEXT-BOOK ON NAVAL ENGINES AND MACHINERY, By JOHN K. BARTON, Commander, U. S. N.
This book is evidently written for one specific purpose, and only one, viz., to furnish information to midshipmen and young officers, and the author never loses sight of his subject from beginning to the end. It is free from prolixity or any attempt to swell the volume with irrelevant material. While covering the whole ground pertinent to the subject matter, there is no part which could have been omitted without positive detriment. The language is simple and direct and very cut clear and easily understood, being obviously made for the book and not clipped, for sake of economy, from some advertising circular.
The text begins with the usual and necessary elementary treatment of the subjects of "Work and Efficiency," "The Action of Steam," "The Slide Valve," "Valve Gear," and "Multiple Expansion Engines"—each subject being presented in accordance with the standard accepted theories and practice, and in a manner found by experience in the class-room to appeal to the understanding of midshipmen.
