From the experience of his numerous aerial excursions, Mr. Wise is of opinion, that, at a considerable elevation, there is a constant and regular current of wind blowing at all times, from west to east, with a velocity of from twenty to forty, and even sixty miles per hour, according to its height from the earth. On the strength of this conviction, he believes it to be perfectly practicable and safe, not only to cross the Atlantic, but even to circumnavigate the globe, in a balloon; and he has expressed his readiness to undertake either of these voyages. About the beginning of the year 1843, he actually proposed to some gentlemen of the city of Philadelphia, the project of making an aerial trip across the Atlantic, in undertaking which, he assured them, he would have as little hesitation as about embarking in the most approved steam-vessel that plied between the ports of New York and Liverpool. At first, supposing him to be in jest, they expressed their willingness to promote the design, but finding that he was in sober earnest, they began to evince conscientious scruples as to the responsibility they would incur, if by any chance his life should fall a sacrifice to the bold adventure. He next determined to petition the Congress of the United States, at their ensuing session, for the necessary pecuniary means; and flattering himself with the hope of the success of his application, to provide against the accidents which might arise from opposing local currents and storms, or from omissions, imperfections, and unforeseen necessities attendant upon all first trials, he issued a proclamation, addressed to all publishers of newspapers in the world, announcing it as his intention to make a trip across the Atlantic in a balloon in the summer of 1844, and calling upon the seafaring community of all climes not to be alarmed should they happen to be in the vicinity of a balloon, either on the ocean or in the atmosphere, but endeavor to give aid to the adventurers. He proposed to have for the car a sea-worthy boat, which would be of service in case the balloon should fail to accomplish the voyage; and the crew was to consist of three individuals--an aeronaut, a sea-navigator, and a scientific landsman.
