Abstract :
IN TIMES when so much thought and attention are given to the streamlined development of modern life, such as aviation, de luxe high-speed trains, airmail, radio, television, sound movies, and other wonders of science, it is quite natural that an industry such as the telegraph should find itself called upon constantly to fill an ever increasing demand for new services or functions created by this world of today. With every new development in modern industry, new needs arise for quick interchange of information — accurate and in written form for permanent record to insure against misunderstanding or forgetfulness. It is these needs which the telegraph, through its system of fast record communications, has been able to anticipate and provide for. Engineering research and developments in telegraphy have fully kept pace with the modern trend, and during the last year or two, there have been brought to conclusion several developments which promise to make the telegraph more necessary than ever to our social and industrial life.
