IENtE 10 RAISE VESSELS
 SAVE RUSSIAN SHIPS.
Japanese Invents Apparatus for Use of Deep Sea
 Divers.

Evolution of the marine world, the raising of battleships that have been sunk, the bringing to the surface of treasure vessels that went to the bot tom years and years ago as well as sunken merchant boats in all parts of the world, is promised by the inven- tion of Washington man. Japanese, whose ingenious brain has been at work at the task long time, prlnci- pally for the benefit of his own nation to enable 1t to gain possession of Rus l sian battleships lost in the late war, writes Washington correspondent of the Chicago Post
 Takao 1wanmi, Japanese employed in the drafting division of the South ern railway in Washington, has invent ed diving apparatus with which eff forts are to be made to raise the ships of war that were sunk during the en- agreements between Japan and Russia. l Two of the sunken vessels are of tbe Russian type, while the same number are those of the inventors native land. The ships are at ths; bottom Of the sea, all within a radius of ten niles from Port Arthur.
 Iwanmi has been at work on the in vention five years. Only recently has he perfected the outfit, however, and not long ago he had b.s apparatus pat ented. The inventor has been !n Wash ington several years. He is Of an in. ventiye turn of mind and has many other devices that he is laboring on from time to time.
 The feature of Twanmi's diving shit is his claim that 1t will allow the diver to go to depth of 300 feet in the wa ter, This has been the weak point of other inventions of this character, ow- ing to the fact that they were not made to resist the pressure of the wa ter below something like 150 feet An other feature of Iwanml's apparatus is that by means of the pumping ma chinery and the lines of hose the man at work far below the waters surface will be able to remain at his task for hours at a lime.
 The air will be supplied by ma chine which Is run by a storage bat tery. The floating paraphernalia will be different from that now in use, in that 1t will not be a boat, but vertical floating buoy This will contain an assistant or two and the air machinery leading to the man working 300 feet below.
 After reaching the vessel as 1t rests on the bottom of the sea it will be com paratively an easy task to bring the old hull to the surface. Having gained his point, the diver will set about to To- cate the holes and openings in the wrecked ship. If the ship went down, as did did those Of the Russians and inc Japanese as we'll the holes made by the shot and shell will be found and repaired. Then the portholes, the matches and the gangways will be ln- spected and where necessary repaired to such an extent that they will be- come water tight. After this task has been completed additional apparatus will be brought into use, and the work of pumping the water from the hull will be started.
 Holes will be bored in the sides of the ship, and into these pipe lines will be extended. The line will be attach ed to powerful pumping engines in vessel on the waters surface, and slow ly but surely the water from the inside of the wrecked boat will be brought out. When this has been accomplish ed the holes will be plugged, the tenn porary anchors removed, and, accord ing to all calculations of the inventor, the steel hull will ascend rapidly to the top. Here it will be attached to line and lowed to the nearest shipyard, to once again enter the service of the ma rine shipping interest of the world
 Iwanmi has already received an of fer for one of his diving suits. He is to receive $1,500 for 1t as soon as placed aboard a ship consigned to the parties interested, who are in Japan. The apparatus is to be made in Balti- more. It will be much like other div ing suits, but will be made stronger by the use of steel ribs These ribs will be all through the rubber, about half an inch apart, and will make 1t possi ble for the diver to go to a much greater depth and stand the water pressure than has ever been accom- plished by means of the other inven- tions Eventually Iwanmi expects to turn his attention altogether to the business which will be brought about by means of his invention.
