The accompanying figures represent a new method of connecting the ends of the sections of submarine telegraph cables, invented and patented in England by W, B. do Blaqniere, of London. It has been supposed that the f ormor methods of joining the ends of telegraph cables have been defective, and that when any of them have been broken, it was at the joints, also that other methods did not allow ef their being connected quickly, hence the present improvement. Fig. 1 is a longitudinal section; a is a inetal tube having at each end a portion, 5, with a thread upon it attached to the other part by a hinge. The central portion of the tube is filled with gutta percha, and has wires passing through it to connect with the conducting wires of the cables. There is :i nut screwed on to each end of the tube to press and secure the ends of the cable. The junction is made between the sections of the cables by bringing them together in the tube when nuts are slipped over the ends of section cables, thus allowing the jointed parts, b, of the tube to be opened so as to permit plastic gutta percha to be filled around the cable. The jointed parts, 6, are then shut down, the nuts pushed off the cables upon the tubes, then screwed up, and the junction is complete. Fig. 2 is a section showing a somewhat different method of forming such joints. The coupling tube, a, is made in two halves, and tie conducting wires of the two sections of the cable are brought together and united directly. The nuts, e c, are slipped off the tube over the ends of the cable, the tube opened, the sections brought together, united, the interstices filled with plastic gutta percha, the tu.be closed around the cables, the nuts passed back over their ends, screwed up, and the coupling is completed. In Fig. 1 the inside of the tube is grooved to receive tho special covering of the cable, and hold it fast like a screw bolt in a nut; but in Fig. 2 the covering wires of the cable are Uirued buck over a metal ring and the form of the tube corresponds to this, so that the cable is locked firm in the tube, and cannot be drawn out of place. A quick and strong method of jointing the sections of marine cables is absolutely necessary in cases of emergency which often occur at sea. At a recent meeting of the Transatlantic Telegraph Company, held in London, the capital was increased to meet additional expenses especially for seven hundred miles of extra cable to be provided for the next attempt. This enterprise moots with the sympathy and good wishes of all men, because, if successful, it will be of world-wide benefit; but we are fearful, from the difficulty of working lines not one-fourth the length of the Atlantic cable, that communication through it is more than doubtful, even if the cable should be laid successfully. The steam frigate Arto-ffara has been completely repaired, and is now on her second voyage to England, to engage in laying the cable in conjunction with the frigates provided from the British fleet. The next attempt to lay the cable will take place, it is presumed, in tho early part of May, \vhen wo hope all will result well in the issue. THE GREAT MYTH.—We arc glad to announce that the mighty humbug which has so often made us gape with wonder is at last caught. A geutleman of Newcastle-on-Tyne, England, informs the London Times that he caught the sea-serpent some time ago in lat. 26 S., Ion. C E., and it proved to be nothing but a gigantic sea-weed, the root of which formed the head, and the leaves the flowing _ mane so often described.
