Thomas H. Russell, A.M., M.E.

Author of “Automobile Driving Self-Taught,” “Automobile Motors and Mechanism.” “Ignition, Timing and Valve Setting,” “Motor Boats: Construction and Operation,” etc., etc.

A book of 600 Questions and Answers, adapted for teaching School, the Machine-shop or before the Board of Examining Engineers. This is the largest, the latest and most authentic book of its kind upon the market. Prepared especially for Home Study. 150 pages. Bound in Cloth, Stiff Covers—In fact it is a regular text book.

The Questions and Answers in this book will be found useful by every Student and Mechanic of Motor Cars and Motoring, as a handy means of reviewing systematic study or in daily work.

It has long been recognized that the Question and Answer method is most effective in fixing in the memory facts gained by study or problems that confront the Mechanic in his daily work; hence it is adapted for the purpose.

The more important subjects connected with Motor Cars, are treated individually, there being a separate set of Questions and Answers for each. For the greater convenience of the reader, the Questions and the Answers in each set appear on separate pages; the Questions can thus be used alone for self-instruction, while the Answers if needed are close at hand for reference.

Minor subjects are covered in a special Catechism, which deals with all the factors which go to make up the power plant of a Modern Motor Car.
