in Secrecy When President Roosevelt was on his latest cruise with the Navy, he received each morning an illustrated facsimile newspaper radioed from New York. That was a Navy stunt to familiarize the Commander-in-Chief with a new communications medium that in Europe has already done efficient war service. Radio facsimile will send a map, or a picture, or signed orders over any wave length by radio or telephone circuit, Distance is, no limitation, for wherever ordinary radio signals will go, so can facsimile. Facsimile's real advantage, however, is absolute secrecy of transmission without resort to clumsy and complicated codes.
The inspiration to make facsimile, in addition io its peacetime uses, a practical wartime instrument derived directly from a study of the Battle of Jutland by Lieut, W. G. H. Finch, a young English-born communications engineer in the American Navy. He found in every phase of that terrifying fleet action' appalling evidence of the inadequacy of ordinary radio communication, Had Admiral Jellicoe, on the night following that 1916 engagement, known and been able to record on his chart ull the facts gathered by his destroyer leaders concerning the course of the German ships, he could have utterly destroyed the Kaiser's High Seas Fleet. Lieut, Finch determined that, it Uncle Sam ever closed battle forces with an enemy in the future, there would be a moving, up-to-the-minute chart on every ship to keep pace with battle changes, so that in the heat of combat every manœuvre could be plotted with accuracy.
