The number of miles of telephone wire in the United States today runs well over the 240 million mark. This is enough to run 1,000 wires between here and the moon, or, if extended as a single pair, enough to carry on a telephone conversation with the sun. Also there are in use today, in this country alone, well over 60 million telephone instruments.
