The Times of Monday printed an extract from the German

weekly technical paper Prometheus describing the general lines of large submarines which are reported to be under construction "by the two foremost naval Powers." These vessels are said to be five thousand tons gross, four hundred feet long, and to be as strongly protected and armed as medium-sized cruisers. It is said that their speed is twenty-six knots above water and sixteen knots below water, that their effective radius is nearly twenty thousand miles, and that they carry thirty torpedo tubes, and are able to lay a hundred and twenty-five to a hundred and fifty submerged mines. We wonder. We expect that it will be found out after all that " the Snark was a Boojum U.C."
