By the time the Congress met, Mr. Wise had enlarged his idea of crossing the Atlantic to a purpose of sailing round the world. In a petition he presented to that assembly, dated Lancaster City, Dec. 20, 1843, he certifies, that by taking advantage of the current from west to east, which, governed by a great general law, blows at all times round the globe, it was quite practicable, from the improved state to which aeronautic machinery can now be perfected, to travel eastward in a balloon with a velocity that would circumnavigate the globe in from thirty to forty days, and that the aeronaut, by taking advantage of the local currents, could vary from a straight course thirty or forty degrees from the latitude of departure, so as to be able to leave dispatches in Europe and China, and return by way of Oregon Territory to Washington City. He therefore prays the Congress to appropriate the money necessary for constructing an aerostadt of 100 feet in diameter of substantial domestic cotton drilling, with a sea-boat capable of enduring the ocean for a car, and so constructed that the masts and rigging may be stowed, ready for erection into sea service at any time that emergency might require. And he concludes by engaging, that, should his proposal meet with the approbation of the Congress, he would readily submit a plan in detail, and would cheerfully superintend the construction of the machinery at his own expense, asking nothing more than the command or directorship of the first experimental aerial voyage round the globe.
