Book Description
Excerpt from Manual of Wireless Telegraphy and Telephony The tremendous strides in wireless during the past ten years have necessitated a revision of this Manual. In the matter of improved apparatus the alternating current transformer has largely taken the place of the induction coil and the auto receptor has all but superseded the coherer receptor in practical installations, with the result that both the working and the efficiency of stations have been greatly improved. Due to these and other advances it has been found expedient to segregate the chapter on The Apparatus of a Commercial Station and treat the transmitting and the receiving instruments separately. Aerials is a subject to which much new text has been added since the flat-tops or T aerial has come into general use together with better methods of suspension than those treated of in the previous editions of this Manual. Furthermore, considerable useful data have been appended under the caption of Suggestions to Operators relating to the management of stations.

Book Description
Excerpt from Works on Wireless Telegraphy and Allied Subjects The Preface of a book is the place in which the Author makes his excuses for writing it, or his explanations of its scope and purpose. Following this practice, it may be mentioned that the writer published in 1902 a little book entitled "Waves and Ripples in Water, Air, and AEther," through The Society for Promoting Christian Knowledge, which was a reprint, with some amplifications, of a Course of Christmas Lectures given at the Royal Institution, London. The last chapter of that book contains a brief reference to the then young art of radiotelegraphy. In the years that have since elapsed, this branch of telegraphy has developed with wonderful rapidity into a unique and most valuable means of communication. The importance of it is shown by the fact that three International Conventions and two Parliamentary Committees have deliberated at length on its regulation and condition within the short space of ten years. A large and highly technical literature has grown up around it, and an industry of considerable dimensions been created by it. Its astonishing achievements have raised a desire in the minds of the general public to know something of its mode of operation and possible future development, but in a form divested as far as possible of unexplained technicalities or abstruse formulae. Many of the popular books written with this object seem to the writer to give insufficient explanations of the physical processes involved.

Book Description
Excerpt from Wireless Telegraphy and Telephony Popularly Explained There have been several books written on the subject for the expert or technical man, but so far nothing has been written that explains it in a way that every one may understand. In this book the authors use simple expressions, con taining no technical words, so that all may obtain a clear idea of the inception and development of this much-talked oi art. We here describe the substance through which signals are sent, the theory of the propagation of waves, method of generating and receiving the waves, the apparatus used, and, finally, the uses, limitations, and possibilities. Of wireless telegraphy both commercially and financially. Providence, R. I. Walter W. Massie. Him You. Charles R. Underhill.
