Preface

The following pages represent the result of an attempt to collect in a comparatively small book such elementary, theoretical, and practical information as will assist in the operation, upkeep, and adjustment of the motor vehicles. This book was written with a three-fold purpose; as a guide for the personal instruction of the car owner, as a hand book for chauffeurs, garages, and repairmen, and as a text book for Automobile Schools. The simplest language has been used and technicalities have been reduced to a minimum. The fundamentals of gas motor operation, as well as the care and operation of the principal accessories of the motor vehicles concerned, are discussed in detail and at greater length than is the usual practice. To' obtain the maximum economy, efficiency, and life of the apparatus the last four chapters of the book should be studied. These chapters are the result of the authors' observations and experience with the great number of trucks, tractors, automobiles, and motor-cycles operating under their supervision. This book is the outgrowth of the authors' former volume " Motor Transportation for Heavy Artillery," which was prepared for use as a textbook in the Coast Artillery School's course in the subject.

The valuable experience gained in connection with their work as instructors in this school has been embodied in this second edition so that the book contains all the information necessary to properly operate and care for motor vehicles. The authors wish to express their indebtedness to the Norman W. Henley Publishing Company for permission to use figures 6, 7,
