them more easily understood by the non-mechanical reader, they are as accurate as relates to proportion of parts as the best engineering drawings and all represent existing mechanisms which are in daily use. The important elements to which attention is directed in the text are clearly designated by arrows and named in the illustration, so the main object of making them intelligible has been attained without sacrificing correct proportion. Any suggestions from readers for improving this work and calling attention to errors, either of commission or omission, will be welcomed by the publisher and the author. This treatise has been entirely revised and all new improvements in automobile engine and chassis design have been included. Attention is directed to the new lesson on electric starting and lighting systems. February, 1917. VICTOR W. PagÉ. SYNOPSIS OF LESSONS 2-Action of Two and Four Stroke Cycle Motors....
