THE AUTOMOBILE HAND-BOOK
OVER 200,000 SOLD
By ELLIOTT BROOKES, Assisted by Other Well-Known Experts
Revised and Enlarged New Edition—The largest and most practical work published. Used by all up-to-date automobile schools as their every-day text-book.over 720 pages and over 329 illustrations. Full Leather Limp, Round Corners, Red Edges. Price, $2.00.
At the present time nearly all automobile troubles or breakdowns may, in almost every case, be traced to the lack of knowledge or carelessness of the owner or operator of the car, rather than to the car itself.
The automobile hand book is a work of practical information for the use of owners, operators and automobile mechanics, giving full and concise information on all questions relating to the construction, care and operation of gasoline and electric automobiles, including road troubles, motor troubles, carburetor troubles, ignition troubles, battery troubles, clutch troubles, starting troubles. With numerous tables, useful rules and formulæ, wiring diagrams and over 329 illustrations.
Special efforts have been put forth to treat the subjects of ignition, and ignition devices, in a manner befitting their importance. A large section has been devoted to these subjects, including batteries, primary and secondary, magnetos, carburators, spark plugs, and in fact all devices used in connection with the production of the spark. Power transmission is thoroughly discussed, and the various systems of transmitting the power from the motor to the driving axle are analyzed and compared.
The perusal of this work for a few minutes when troubles occur, will often not only save time, money, and worry, but give greater confidence in the car, with regard to its going qualities on the road, when properly and intelligently cared for.
A WORD TO THE WISE
The time is at hand when any person caring for and operating any kind of self-propelling vehicle in a public or private capacity, will have to undergo a rigid examination before a state board of examiners and secure a license before they can collect their salary or get employment.
Already New York State has enacted such a law and before long, with a positive certainty every state in the Union will pass such an ordinance for the protection of life and property.
Remember this is a brand new book from cover to cover, just from the press—New Edition—and must not be confounded with any former editions of this popular work.

Complete Examination Questions and Answers for Marine and Stationary Engineers
By Calvin F. Swingle, M. E. Author of Swingle’s Twentieth Century Hand Book for Steam Engineers and Electricians. Modern Locomotive Engineering Handy Book, and Steam Boilers—Their construction, care and management
This book is a compendium of useful knowledge, and practical pointers, for all engineers, whether in the marine, or stationary service. For busy men and for those who are not inclined to spend any more time at study than is absolutely necessary, the book will prove a rich mine from which they may draw nuggets of just the kind of information that they are looking for.
The method pursued by the author in the compilation of the work and in the arrangement of the subject matter, is such that a man in search of any particular item of information relative to the operation of his steam or electric plant, will experience no trouble in finding that particular item, and he will not be under the necessity of going over a couple of hundred pages, either, before he finds it because the matter is systematically arranged and classified.
The book will be a valuable addition to any engineer’s library, not alone as a convenient reference book, but also as a book for study. It also contains a complete chapter on refrigeration for engineers. 367 pages fully illustrated, durably bound in full Persian Morocco limp, round corners, red edges.
