- Although the history of practical electric telegraphy does not date much further back than the middle of the, 9th century, the idea of using electricity for telegraphic purposes is much older.
There is an extensive telegraphic system linking the towns of the province to one another, and, through the surrounding countries, with Europe and the rest of the world.
There is a direct telegraphic service to Gondokoro and Khartum and to Mombasa.
There are no roads in the province, and very little internal communication and trade; but a wireless telegraphic system has been installed in communication with Rhodes: and there is a landline from Bengazi to Tripoli.
The word is still sometimes employed in this sense, as of the ship's telegraph, by means of which orders are mechanically transmitted from the navigating bridge to the engine room, but when used without qualification it usually denotes telegraphic apparatus worked by electricity, whether the signals that express the words of the message are visual, auditory or written.
