Six more submarines are said to be building at Cronstadt. Most of the reports of these are mythical, more especially that which credits one of these, “a vessel which combines in itself the properties of a submarine and an ordinary warship,” with a speed of “60 knots on the surface and 30 knots submerged.” [Sidenote: Brazil.] Señor Mello Marques, formerly of the Brazilian navy, has invented a new type of submarine boat, which was tried last year as a model in a tank in the presence of the President of the Republic, the Minister of Marine, and others. The propelling power appears to be electricity solely. It is stated that the Government has decided to have a larger boat built for the final trials. [Sidenote: Germany.] Experiments have been carried out during the past few years with submarines in Germany, but few details are obtainable. A boat designed by an ex-lieutenant of the German navy was built to the order of the Cyclops Company, Messrs. Schwartzkopff and Messrs. Howaldt, in the yards of the last-named firm. It has been stated that this boat has made 16·5 knots on the surface and 9·5 beneath. [Sidenote: Norway.] As some Norwegian naval officers were present at the trials of the _Fulton_ last autumn, it is thought possible that Norway will shortly acquire one or more of the _Holland_ type. Admiral Borreseu is reported to have asked for £35,000 for this purpose. [Sidenote: Sweden.] Mr. Euroth, a Swedish engineer, has offered a submarine to the Swedish Government. Its dimensions are—length, 82 feet; beam, 13 feet; diameter, 11½ feet; displacement (light), 142 tons; (submerged) 146 tons; engines 100 h.p., supplied by two boilers heated by oil; speed 12 knots surface and 6 submerged. The boilers do no function when the boat is submerged, the engines being then partly driven by the steam already generated, and partly by compressed air stored fore and aft. [Sidenote: Portugal.] In October last trials were made with a model of a new submarine invented by Lieutenant Foutes, who designed the _Plongeur_, built in Portugal, and tried in 1892. APPENDIX V THE “LAKE” SUBMARINES The Right Rev. John Wilkins, from whose book “Mathematical Magick” some extracts have been given, was far-seeing enough to predict that a submarine vessel would prove of great value in the discovery of submarine treasures, “not only,” as he expressed it, “in regard of what hath been drowned by wreck, but the several precious things that grow there, as pearl, coral, mines, with innumerable other things of great value, which may be much more easily found out and fetched up by the help of this, than by any other usual way of the Urinators.” Could newspapers and magazines but find their way to the shades, Dr. Wilkins would be enchanted to find that his dream has been realised, and that a vessel has actually been constructed for the purpose of harvesting some of the treasures of the deep.
