PREFACE.

In offering the third edition of this book to the Public, especially to that class known as Steam Engineers, the author desires to lay before them such facts and general information as he has gained by an experience of many years in the business. In doing this he wishes to help to elevate, and make more competent a large class, which in this age of Steam, has become an important element in the world's advancement, and upon which largely depends the safety of transportation of passengers and freight throughout the world. Also, in the busy hives of industry everywhere, much depends upon the economical production, care, and useful application of Steam.

In presenting this book, it is not claimed that the rules, tables and formulas for calculation are entirely new, the author is largely indebted to such works as Haswell, Winslow, Briggs, Bacon and Williams, for which he makes due acknowledgement.

But seeing from many years intercourse with the class of men herein named, the great need of a practical treatise on Steam Engineering, presented in such a form as would be readily understood by those directly interested, and especially beneficial to young engineers, he cannot but hope this work will reach the class for whom it is intended, and be found interesting and helpful to them.

Slight changes have been made in a few instances, and the page on electric lighting has been re-written, to meet the greatly reduced cost of electric lighting machinery, materials, and supplies. About twenty new pages have been added, and some which did not seem as useful have been omitted. The book, as improved, is submitted to the public with thanks by the author for their appreciation of the former editions.
