engines, and can carry 15 tons of fuel. Yet another and more advanced type of submarine is stated to be under consideration and possibly under construction. It is to be larger, according to report, than any existing submarine, and is to carry a gun, which it will come to the surface to discharge. Is this to be the forerunner of a new cruiser, to be equally at home and equally dreaded, whether it be operating at the surface or beneath the waves, advancing stealthily upon its foe? The Japanese, when they decided upon importing some submarines from this country, had two specially built at Barrow. It was not thought advisable to send them under their own power, or in tow of tugs, to the Far East, so a special vessel was built for their accommodation. For two-thirds of her length her main deck could be removed and her bottom was constructed to permit of the two submarines lying side by side. In order to get them on board, this steamer, which was called the _Transporter_, was sunk in dock at Liverpool, the submarines were floated into place and the water was pumped from the dock, and, of course, from the steamer also. As it subsided, the submarines were carefully adjusted in their cradles, and when this work had been completed, the _Transporter_ with her strange cargo returned to Barrow in order to be prepared for the voyage to Japan.
