Excerpt from ABC of the Telephone: A Practical and Useful Treatise for Students and Workers in Telephony, Giving a Review of the Development of the Industry to the Present Date, and Full Descriptions of Numerous Valuable Inventions and Appliance, Together With Very Many Illustrations, Diag As is indicated by the title, this book is an elementary and general treatise. It deals with the telephone industry and the leading features of its development to the present time, in such a fashion and in such language as to enable the student and the non-professional reader to derive an intelligent idea of broad facts and general principles. Of course, with such an aim in view, it cannot be claimed that the book will furnish all the details and formulae that may be required by the thoroughly equipped telephonist. Such facts, at best, can be mastered only after practical experience and careful training, and, without this, no book can guarantee a thorough education in the pro fession of constructing and maintaining telephone plants.
