WIRELESS TELEGRAPHY.

Mr Charles Bright, the soil of Sir Charles Bright, who laid the first Atlantic cable, and himself a great authority on eablo and land telegraphy, lias been reassuring the frightened shareholders of the cable companies. He is of the opinion that the Marconi system of wireless telegraphy is not at present a serious rival of the cable system. In the October number of the Monthly Review be gives his reasons, and records many interesting facts. Ho points out in a sentence the principle of Marconi’s system. It is fundamontaliy based, lie says, on the coherer receiving relay, which is an excessively sensitive and delicate instrument. “ While having obvious advantages, an apparatus of this character is, of necessity, extremely liable to got out of adjustment. For this reason it is somewhat unreliable, and apt to give confused and false signals. The Marconi coherer of 1596 is, moreover, more or loss readily affected by its surroundings and general conditions, including atmospheric and other natural and electric disturbances.” On the other hand, Mr Bright reveals a great opportunity for the Marconi system , even in its present state. “ From a strategic point of view,” he says, 11 as well as from a general maritime and life-saving standpoint, Great Britain and Ireland should be provided with a complete system of telegraphic communication round the entire coast-, putting every coast station into connection with various inland centres and military stations. It is a piece of work which would bo most effectively accomplished by wireless methods in preference to overhead lines. For maintenance reasons, too, cables arc inefficient in England, owing to abrasion against rocks, strong tides, kinks, etc.”
