telegraph wires
Morse code carriers
Telegraph wires are the metal cables strung between poles that carried electrical signals for telegraph communication.
Before telephones and the internet, telegraph wires formed the first long-distance communication network.
The phrase evokes 19th and early 20th century landscapes—rows of wooden poles lining railways and roads: Birds perched on the telegraph wires.
