TALKING BEACONS
The first talking beacon in the world is now in operation at the Cuiwbrae Lighthouse, off Little Cumbrae, a small island in the mouth of the Clyde, in Scotland (reports the London Daily Mail). The beacon promises to solve the fog problem at sea. The apparatus consists of a wireless gramophone which, used in conjunction with the lighthouse foghorn, tells a ship's wireless operator exactly how far his ship is from the lighthouse. The record " played" on the Cumbrae gramophone gives the name Cumbrae. This, being transmitted by wireless, is picked up immediately by the ship's operator. The blast from the lighthouse foghorn, sent out at the same time, takes longer to < reach the ship, and the lapse of time between the two signals enables the wireless operator to calculate within a few yards his distance from the lighthouse. The inventors of the talking beacon are MJr C. A. Stevenson, of Edinburgh, and his son, Mir D. Alan Stephenson. The family, of which Robert Louis Stevenson, the novelist, was a member, has been engaged upon lighthouse work for generations.
