QUARTZ CRYSTALS
DISCOVERY IN UGANDA (British Official Wireless) RUGBY, 16th June. The discovery within the British Empire of quartz crystals of sufficiently fine quality to be used foi maintaining the frequency of radio transmitters is reported by the Imperial Institute. The now source of supply is Uganda, in a district where alluvial gold is being washed. Commerical tests are stated to have proved satisfactory. Hitherto Brazil and Madagascar have been the two chief sources of these crystals. Besides being used in normal radio transmission, quartz crystals are in demand for apparatus required in depth-sounding at sea, in detection of the presence of rocks and icebergs and other dangers to shipping.
