Schroeder's Balloon

[From tho Baltimore Gazotte.] e erick F. Schroeder, who is constructing a steerable air-ship, as previously announced, in which he designs crossing the Atlantic, is making rapid progresa with the work. The balloon part will have a capacity i'or 135,000 cnbic feet of gas, and a lifting power of 12,000 lbs, inclusivo of its own weight. It will have one puiling and one pushing propeller, front and rear, making, nccordiiig to the current that the ship is in, 600 to 1,200 revolutions a minute. The higher the current the greater the revolutions, and vice versa. The propellers work inependently, so that the aeronaut can turn the boat around upon its own pivot, and setting the ship against the current of the air by just giving the propeller so much of a revolution as to overeóme the power of I the current, which it is expected will cause tíie ship to remain still in air over ! any given point. Mr. Schroeder stated yesterday that with photographic nents lie can take views of any portion ' if the country or coast. He believed that f rom a certain height ie can see the bottom of every river, ake and ocean through bis instrumenta, md be able to take photographie views )f tliem. David Bachracli, }her of tliis city, will assist Schroeder in hese scientific observations and will ravel with him. Mr. Sckroeder, continuing, said: The ! ,vay I intend to prepare my balloon it I wïil be perfectly air-tight, and will, ;herefore, remain in the air any length jf time. I can make the longest of trips issisted by my motive power, and the gas ípparatus will add a supply of gas to the oalloon, as requiree. Moving in the iigher currents toward the north, the ipper atmosphere becomes warmer and the lower atmosphere colder, so that there is nothing to prevent me from 3rossing the North Pole in a higher atmosphere, where it is quite warm, to flnd Dut or solve a scientiflc problem for which millions have been expended. Mr. Schroeder showed, by the large j drawing of different sections of the I balloon, a mast, which would be placed in it from the boat to the center, braced with steel shafts, which will be attached to the center of the balloon by wire cams. The outside of the central portion of the balloon will also be ecured by a hempen belt, 3 inehes thick and 248 feet in circumference. By this arrangement, should the balloon collapse, tlie aeronaut would still be protected below, and by the aid of his steering apparatus, slowiy descend in safety. In three weeks from yesterday (Thnrsday) the contract. for work upon the several sections of the balloon expires, and when completed the first exhibition will be given upon the hippodrotne lot, xjorner of Boundary and Madison avenues. The Schroeder Air-Skip Company was incorporated upon the 8th of the present mouth. The offlcers are: President, Bernard Stol te; Vice President, P. L. Eamsel; Treasurer, Gustav Stoppelhaar ; Secretary, E. Lohmeyer; Directora, Dr. Callenious, B. Diebitch, John Stalfort, Julius Kupp, John M. Link, A. Scharon, Francis Althoff and H. Manner. The company havo a cash capital of $3,000, and have issued 600 sharcs at $5 each, 500 of which have alroady been taken. The first trip of the air-ship will be from Baltimore to New York, and not to Washington, as jn-eviously intended. The balloon will be exhibited in New York and other cities of the Union, and the trip across the Atlantic will not be undertaken untü the spring of 1876. I Much interest is manifested in Europe I at the result of the experiment.
