How it got there, how it was built, in what way it managed to dive beneath the waters, whether it walked or ran or swam or turned somersaults when it got down among the mermaids in the cool grottoes at the bottom cf Lake Winnebago, anxious readers were It It to imagine for themselves, the reports being confined to beautifully vague statements in which the new boat was ad way* said much more wonderful than Verne’s imaginary Nautilus. In to give our readers the real story of the mysterious boat we present here a signed vStatement, written especially for this paper by the inventor of the submarine boat, and illustrated from photographs supplied by him.to be Jules orderOSHKOSH, Wis., Jan. 4.—The submarine boat is a winner, and the time has come when, in justice to myself, I feel I should respond to yo.ir invitation to make public the resuit of my experiments. I have put the boat through a series of the most trying tests and she has come through them all with flying colors, if such an expression can be used in connection with a boat that travels beneath the waves, where colors can’t very well be flown, haustive have been would state that the submerged for eight ten hours, with from three to four passengers on board, and has remained under water with thr?e passengers on board for over three hours at a stretch without any connection with the surface whatever. This was done for several days in succession. She has been maintained upon an absolutely level keel for over three hours at a time, observations as to maintenance of this condition being made by a passenger upon an ordinary spirit level, the air bubble of which did not during this time vary a hair’s breadth from the level mark. During the time I have been secretly carrying 011 these tests in Lake Winnebago over 300 descents and voyages have been made by the submarine boat. Between sixty and seventy passengers have been carried at different times. A deptn of thirty-two feet, the deepest water in that vicinity, has been navigated.A constant depth with a variation of less than one foot from a given mark has been maintained for several hours at a stretch, both while the craft was j suspended motionless in the water and at rest while under headway. xAs regards the motive power, the craft can be operated in any part of the world, in any waters whrie ordinary kerosene oil can he purchased, the extent of the trip being limit d only by the supply of oil that can be carried in the storage • tanks.All operations of charging, storing or other expenditure of power necessary for the- operation of the boat, or the working of any machine connected with it, depend primarily upon the supply of oil carried. With an increase of the power expended any reasonable speed can be maintained, either above or below water.With No Other Fuel Than Ker-tlteAIR SUPPLY A SUCCESS.Lowest Depths of Lake Win-AroldeHebtheiHeba w Li of 1worpoorTcnebago and Travels UnderThe depth descend is is merely the shell,The ait supply, which is obtained from reservoirs, has been auite a success. The capacity of the present air machinery is sufficient to maintain the atmosphere of the boat in a respirable condition for twenty hours with two men in the boat. At the option of the officer In charge of the motive power, the brat can be held to a certain determined depth indefinitely and maintained by automatic mechanism upon a level k^el for any length of time that she may remain submerged.to which *this craft can safely estimated at 500 feet. As this a question of the strength of of crurse, any reasonable or desirable depth can be attained by building shells strong enough to withstand the pressure of the added w’eight of water. lTpon the size of the boat depends its power, speed, length of submergence and other qualiffcationL increased to any extent purpose to which it is to This submarine boat is 65 feet long, 14 feet in diameter and 7 1-2 feet high at the highest point. It is built of 5-16 armor steel upon a steel framework. The forward end of the boat is armed with a steel spur of intense penetrating capacity. The maximum speed attained at the surface was fourteen miles an hour,with an expenditure approximating fcrty-five horse power. Its speed whenWater at Great Speed.prajTfItbersPar:daybersspoiIethatwillSumThese can be suitable for the be put.submerged varies from one to ten miles per hour, depending principally upon the clearness of thu water and the limits ofvision.The boat is not intended solely for wraging war on the leviathans of the deep, although with its steel nose it can sink any battleship afloat with ease. I hope to see it put to useful and peaceful work in locating wrecks, carrying on coast and geodetic surveys, pearl coral and sponge Ashing, surveys for individual enterprises, cable laying and repairing, rendering aid to wrecking associations corporations and divers, and lor general scientific exploration in deep water.RICHARD RADDATZ.CASCADE3 OF GOLDEN COIN.Mr. Raddatz says nothing regarding thevast store of wealth that awaits, at the bottom of the ocean, the coming of the first submarine crew. The cascades of golden coins that -vere emptied from the coffers of sunken treasure ships, to fill the money chests of Jules Verne’s Captain Nemo, are still in store for the man who can reach them. There need be no hurry about it, either, for there is enough treasure in the grasp of old Father Neptune to make the crews of a big fleet of submarine boats rich beyond the dreamsof avarice.elect a si 11*118 amime umitternj Afcingalloffic ByTehereflt;whofantfroTthecurpreTalnthetheotbThthe;on ,f the Pacific coast dit
