Book excerpt: Excerpt from Modern Practice of the Electric Telegraph: A Handbook for Electricians and Operators During the quarter of a century which has elapsed since the introduction of the Electric Telegraph in the United States, those engaged in its service have been almost entirely dependent upon verbal instruction, and long practical experience, for a thorough technical knowledge of their profession. The works accessible to the American telegrapher have been of a popular, rather than of a strictly scientific character, or else of so elementary a nature as to be of little service except to the most inexperienced students. It is true that a number of excellent foreign works have appeared within a few years; yet the difficulty and expense of obtaining them, as well as their want of applicability to the American telegraphic system, has prevented their general circulation among the class for which this work is more especially designed. The unexpectedly favorable reception which has been accorded to the first three editions of this work, has led the author to believe that it has, to some extent, supplied the acknowledged deficiency which had previously existed in this branch of literature. The present edition has been carefully revised, as well as enlarged by the addition of much new matter, and is believed to embrace all the recent discoveries and improvements in practical telegraphy, which have successfully passed through the test of actual experience. The methods of testing telegraph lines and apparatus by actual measurement, which are now universally employed in Europe, and to some extent in this country, have been treated upon to an extent commensurate with the importance of the subject. It is hoped that, with the aid of this work, the student may obtain a complete and satisfactory knowledge of this useful and beautiful system.
