in A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy. An electrical telegraph uses electric current and magnetism to convert the manual typing of codes that represent words, into electrical impulses.
These impulses are transmitted over a metallic circuit (overhead wires or underground cables) to a distant location. Peel-Conner Telephone Works Ltd.
