——— SPLICING THE OABLE. In the many accounts that have now been given of submarine cables, the manner of splicing has been scarcely at all described. A great variety of;circum- stances render it necessary that the cable should be cut and joined again, and the joining is effebted as follows :—The coverings of the core, whatever they may be, are first ravelled back for a considerable dis- tance, generally about 60 feet, and the core itself is cut straight through. The operator then warms the gutta percha of the core over a spirit lamp, and moulds it back with his fingers as it softens until the conductor is laid bare for about two inches. The conductor is then washed with naphtha, so as to cleanse it from all grease or extraneous matter, and solder is run among the wires of which it is com- posed, so as to unite them into a solid rod. The end of this rod is filed obliquely into a smooth soarf, and to this the other end, similarly prepared, is ap- plied. Fine copper wire is then wound firmly round the joint, and the ends of this wire are soldered to the conductor, one on each side of the joint. Solder is also run over the whole, and the gutta percha re- placed by the fingers in the same way that it was moulded baok. Alternate layers of gutta percha and Chatterton's compound are then applied, so that the core over the joint is somewhat thicker than else- where, and the covering of yarn or wire, or both, are replaced in the ordinary manner of nautical splicing. The effect of the whole process is to make the joint the strongest part of the cable. If the ends of the original conductor could be pulled apart the wire wound round the scarf could be elongated to the extent of 10 inches, and would still give passage to the electric current.
