PERSONAL.

The fireman, so called, in steam service of any description, should and does on the average receive double the compensation of a man who has only his labor to bargain for.

In addition, he exercises his skillful vocation in sheltered places and is almost the last of the employees of a plant to be “laid off” and is certainly the first to be called on again after stoppage.

Still further, the fireman has an almost equal opportunity, with the best shop trained machinist, for advancement to the position of engineer in charge of the most extensive steam plants.

Now! this increased pay over ordinary labor and other numerous advantages accruing from the position, demand a generous return, and in ending this work, the author suggests these “points” for observance to the aspiring student, whether engineer, fireman, or machinist, namely—that sobriety should be held one of the first elements of strict observance; an unresting tidiness of person and premises; dignity of conduct, as being owed to the rising profession of steam engineering; and lastly, an unswerving fidelity of trust, which may include honesty, truthfulness and courage.

ERECTING AND OPERATING $3

——JUST ISSUED——

Rogers’ Erecting and Operating
for Engineers, Machinists and Millwrights

AUDEL

A PRACTICAL HANDBOOK on Excavations, Foundations, Structures, Millwrighting, Shafting, Belting, Piping, Boilers, Engines, Installing Machinery, etc.

In order to become an expert at the erection and operation of modern machinery and appliances, judgment must be added to execution; now as judgment cannot be taught in writing, further than in laying down certain principles of procedure, therefore the book is largely personal.

The method of instruction followed is to deal with the various subjects mentioned, each consisting of nearly the same number of pages and illustrations, indicating the course of study.

Working Drawings, Foundations, Excavating, Piling and Grillage, Brick Work, Concrete, Reinforced Concrete, Millwright’s Tools, Steel Square and its uses, Bridge Work, Structures, Scaffolding and Stagging, Rigging Knots. Hitches and Splices, Chains and Tackle, Steel Structure Work, Roofing, Blacksmithing. Tool Dressing, Belting and Pulleys, Shafting Lining, Speeds, Piping and Joints, Plumbing, Steam Boilers and Accessories, Chimneys, Drafts, Steam Engine Operation, Engine Foundations. Valve Setting, Water Power Installations, Steam Turbines, Pumping Machinery, Electrical Installations, Motors, Wiring, etc., Refrigerating Systems, Rules, Receipts, Metallic Compositions, Useful Tables. Ready Reference Index.

By following this plan, and with the aid of the ready reference index to be found at the end of the volume, the work becomes a reference book, as well as a course of systematic study in Mill Engineering.

This volume is convenient in size, handsomely and durably bound in black cloth, having gold edges and titles; containing 600 pages, illustrated by over 500 drawings and illustrations of practical work. It is in every way a generously good book both in contents and manufacture.

PRICE $3 to any address.

ADVANCED MACHINIST $2

THE trade of the machinist is peculiar in that it is a preparation for so many positions outside of it.

It takes a man of good natural ability and of considerable education—not always from books—to make a first-class machinist; so that when one is well qualified he is also prepared for many other openings.

The aim of this work is to point the way of advancement to those who become fitted to assume these responsibilities and rewards.

The advanced machinist is a work of sterling merit, a few of the hundreds of subjects are here named, but they in no way show the scope of this work, which must be seen to be appreciated:

A Course in Machine Shop Mathematics; Various Measuring Instruments and Their Uses; Screw Cutting; Boring; Milling; Drilling; Grinding; Punching and Shearing; Bolt Cutting Machinery; Special and Auxiliary Machines; Shop Management: Work Shop Receipts and Devices, etc., etc.

The personal character of the book appeals to all in any way associated in the machinery and allied trades.
