Description:
Another telegraph was invented by Samuel Morse. The use of this telegraph is almost the same as electric telegraph. This was used for communcations during those days.
My own experience: Physically, I have never touched this device every in my life, but i have seen it in multiple T.V. shows and documentaries.
