The great problem is at length solved. The air, as well as the earth and the ocean, has been subdued by science, and will become a common and convenient highway for mankind. The Atlantic has been actually crossed in a Balloon; and this too without difficulty -- without any great apparent danger -- with thorough control of the machine -- and in the inconceivably brief period of seventy-five hours from shore to shore! By the energy of an agent at Charleston, S.C., we are enabled to be the first to furnish the public with a detailed account of this most extraordinary voyage, which was performed between Saturday, the 6th instant, at 11, A.M., and 2, P.M., on Tuesday the 9th inst.: by Sir Everard Bringhurst; Mr. Osborne, a nephew of Lord Bentinck's; Mr. Monck Mason and Mr. Robert Holland, the well-known aeronauts; Mr. , author of "Jack Sheppard," &c.; and , the projector of the late unsuccessful flying machine -- with two seamen from Woolwich -- in all, eight persons. The particulars furnished below may be relied on as authentic and accurate in every respect, as, with slight exception, they are copied verbatim from the joint diaries of Mr. Monck Mason and Mr. , to whose politeness our agent is also indebted for much verbal information respecting the balloon itself, its construction, and other matters of interest. The only alteration in the MS. received, has been made for the purpose of throwing the hurried account of our agent, Mr. Forsyth, into a connected and intelligible form.
THE BALLOON.
Two very decided failures, of late -- those of and -- had much weakened the public interest in the subject of aerial navigation. 's scheme (which at first was considered very feasible even by men of science,) was founded upon the principle of an inclined plane, started from an eminence by an extrinsic force, applied and continued by the revolution of impinging vanes, in form and number resembling the vanes of a windmill. But, in all the experiments made with models at the Adelaide Gallery, it was found that the operation of these fans not only did not propel the machine, but actually impeded its flight. The only propelling force it ever exhibited, was the mere impetus acquired from the descent of the inclined plane; and this impetus carried the machine farther when the vanes were at rest, than when they were in motion -- a fact which sufficiently demonstrates their inutility; and in the absence of the propelling, which was also the sustaining power, the whole fabric would necessarily descend. This consideration led to think only of adapting a propeller to some machine having of itself an independent power of support -- in a word, to a balloon; the idea, however, being novel, or original, with Sir George, only so far as regards the mode of its application to practice. He exhibited a model of his invention at the Polytechnic Institution. The propelling principle, or power, was here, also, applied to interrupted surfaces, or vanes, put in revolution. These vanes were four in number, but were found entirely ineffectual in moving the balloon, or in aiding its ascending power. The whole project was thus a complete failure.
It was at this juncture that Mr. Monck Mason (whose voyage from Dover to Weilburg in the balloon, "Nassau", occasioned so much ,) conceived the idea of employing the principle of the Archimedean screw for the purpose of propulsion through the air -- rightly attributing the failure of 's scheme, and of 's, to the interruption of surface in the independent vanes. He made the first public experiment at Willis's Rooms, but afterward removed his model to the Adelaide Gallery.
Like 's balloon, his own was an ellipsoid. Its length was 13 feet 6 inches -- height, 6 feet 8 inches. It contained about 320 cubic feet of gas, which, if pure hydrogen, would support 21 pounds upon its first inflation, before the gas has time to deteriorate or escape. The weight of the whole machine and apparatus was 17 pounds -- leaving about 4 pounds to spare. Beneath the centre of the balloon, was a frame of light wood, about 9 feet long, and rigged on to the balloon itself with a network in the customary manner. From this framework was suspended a wicker basket or car. The mode of arrangement of the rudder and of the Archimedean screw, will be best shown in the annexed engraving, which we have kindly been permitted to use.
