Abstract
THIS book deals in a thoroughly practical manner with the construction and erection of overhead telephone lines and the laying of underground cables. The author's long experience as a telephone engineer enables him to write with authority on the subject, which he treats in all its important engineering aspects, from the best methods of preserving the wood used for poles to the final electrical testing of the finished line. American and continental practice is described as well as British methods. Telephony has always been re garded as a branch of applied science in which this country can by no means claim to be to the fore; the perusal of Mr. Owen's book certainly lends support to this belief, as the examples of continental methods which are quoted show in many instances considerable superiority. The theoretical explanations which are here and there required to show the necessity of certain methods of construction are expressed in clear and non-technical language well suited to linesmen and others who are not technical experts, for whom the book is largely written. A large number of illustra tions help to explain the text; the book should prove very useful to those engaged in, or having anything to do with, telephone work, and may, moreover, be read with interest by all who care about the practical applications of science.
Telephone Lines.
