a certain cabaret near the home of an Acting County Judge of Texas, U.S.A. there was an outdoor loudspeaker which caused the judge considerable annoyance. He complained that it was disturbing him and his children, who were ill, However, his complaints fell on deaf ears, and nothing was done about it.

OG has long been recognised by '" aviators-all over the ‘world as their most dangerous. enemy. The neon light, first produced by the -French physicist, Georges Claude, in 1910, by passing an electric current through a glass: tube filed with neon gas, is of especial value in guiding flyers through ity fogs to invisible airports. It is ye of several recent inventions which are helping prevent accidents in fog. ‘Another is the radio beacon. It provides a bath or beam of radio signals hich an airplane pilot can follow y the intensity with which they are zeceived. Experimental altimeters have been designed to tell fiyers ka height above the ground by the tgme required for sound waves or radio waves to be reflected back from the earth to the airplane. At sea, the radio compass protects vessels from crashes and allows them to determine | their position in a blinding fog. It indicates the direction of a radio signal, thus warning of the approach of other vessels moving through the fog, and giving the direction of points on land. A new invention in England . enables the captain of a fog-bound boat to detect faint sounds of distant fog sirens as he edges toward the shore, The device picks up the feeble sounds, amplifies them, and also converts them into light signals .which appear as small light spots on a screen, ~
