Excerpt from Gilbert Signal Engineering: Complete and Thorough Instructions, in All Forms of Signaling for Boys
To do big things, just as men do who are experts in a certain kind of endeavor, I believe is the greatest wish of every boy. I know when I was a boy it was very interesting to me to find out all I could about electricity, chemistry and other practical subjects because they held my attention. There was all kinds of fun in this for me. Whenever I got working on my experiments I had the greatest amount of pleasure. Let me tell you, too, I was a happy boy when I had completed my work and could show it to others.
I remember how I used to watch army men at signal practice. It was mighty fascinating to see them at the camp with their apparatus and to observe the methods they used to send messages. It looked hard, but when I thought it over it seemed very easy.
Signaling will prove just as interesting to you as it did to me, and because I think it means a great amount of fun for you, I have had this book prepared by a man who was an expert in signals and who did very fine work in the Navy as a member of the Signal Corps. Every detail is explained with the greatest care. The facts are authentic and you can depend on this book to give you a thorough knowledge of signaling. You can learn about signals from the very beginning when firebrands were used in a primitive fashion many years ago to the present time when messages are flashed and sent by the most modern inventions.
