The Mine That Hears
Caption 1: As a submarine progresses through a minefield in the effort to reach shipping in a harbor,
the hum of its electric motor is heard by microphones on the mines. The vibrations picked
up by the microphones are electrically transmitted to shore and converted into visual signals
by incandescent lamps corresponding in number and position with the microphoned mines
Caption 2: The mines, provided with microphones to hear the vibrations of ships which seek to enter a harbor, are arranged in numbered squares. A luminous indicator on shore, marked off into squares corresponding in number with those of the mines is electrically connected with the microphones. Each mine-square is represented on the indicator by a lamp, which glows in its proper square on the luminous board as soon as a hostile ship enters and is heard. Thus it is possible to follow by the successive flaring up of lamps the course of a submarine or battleship threading its way through the mine-field and to explode the right mine
