TAPPING THE TELEGRAPH MR PREECE AND THE BIG SUB- MARINE GABLES. "The British steamer 'Oxus' arrived at New York on Friday, and reports tapping the Mexican cable between Galveston and 'Tampico on March. 17th. By this means a cabled report of each round of the Corbett- Fitzsimmons fight was received on board." The- above item suggested to^ a "Daily Mail" representative so many possibilities for fraud- ulent eavesdropping on the great Atlantic cables that he hastened to the engineer-in- -chief of the Postal Telegraphs, Mr W. H. Preece, C.B., F.R.S., to have his fears and these of the general public tianquillised by that gentleman's opinion as an expert. "No, there is little fear," said Mr Preece, "of such an occurrence taking place in con- nection with one of the Atlantic cables with- out such an interruption to the electrical cir- cuit that would immediately proclaim the in- terference to those in charge of the cabling instrument? on shore. Then again, only a steamer properly equipped with grappling apparata adapted for cable work could cut and pick up a submarine lisie far enough from land not to be visible. The Atlantic cables, of which there are eleven, lie along the ocean's bottom, about three miles from tha surface. When grappled by the irons of a surface. When grappled by the irons of a cable steamer, owing to the tautness with which the iinesi lie, a cable cannot be raised more than half a mile from its resting place. While thus held pendant it is cut by a blade in the grapnel, and one end brought to the surface across the ship's bows. The other end is also raised, an instrument placed be- tween the two, and communication establish- ed with the shore stations. Of course, the cutting of the cable interrupts all communica- tion. and is immediately apparent to the ,officials on land, arid, in addition, would ens -tail the labour of many hours. "In time of hostilities a steamer fitted ffith "the proper grappling instruments might sever the 11 of the Atlantic cables in a comparative- ly brief space, but any attempt to establish -communicaition between them would be a much more difficult and laborious matter. "This is a section of an Atlantic cable," the engineer-in-chief continued, producing a well-pitched looking object about an inch in diameter, with a score of fine, thin copper wires, sUITourided" by an impregnable insula- ting sheathing. "The fact that the duplex system-that is, the transmission of two mes- sages, one from each end, at the same time— is In use on these cables, make an attempt to tap them impossible."
