A balloon made by Montgolfier was used. It was 75 feet high, 45 feet wide, and spheroidal in form--heated air being the motive power. The bold aeronauts, on this occasion, were the naturalist Rozier and the Marquis d'Arlandes, a major of infantry. From the gardens of the Chateau of Muetta they ascended on the 21st November 1783. In the car there was a quantity of ballast, and a provision of straw to feed the fire. The balloon mounted at first with a majestic steady motion, gazed at in breathless wonder by thousands of spectators, who assembled not only in the neighbourhood of the Chateau, but clustered on every point of vantage in Paris. When the daring voyagers reached a considerable height, they took off their hats and waved them to their friends below, and the multitude-- realising, perhaps, that that which in former ages had been deemed the dream of visionaries, was at last an accomplished fact--responded with enthusiastic acclamations until the balloon passed upwards through the clouds and was lost to view. It would seem that these first aeronauts were of different temperaments; for, after they had reached a height of nearly 3000 feet, and the earth was no longer distinguishable, the Marquis began to think that he had seen enough of the upper regions, would fain have descended, and murmured against his companion, who still kept feeding the fire. Apparently his alarm was justifiable, for Rozier continued recklessly to heap on fuel, until he almost set the balloon on fire. On hearing some cracks from the top, and observing some holes burning in its sides, the Marquis became so alarmed that he compelled his companion to desist, and with wet sponges stopped the conflagration, which had actually begun. When the fire diminished, however, the balloon began to descend much quicker than was safe or agreeable, and the marquis himself began to throw fresh straw on the fire to enable them to clear the roofs of Paris. This they did very dexterously, considering that they were so unaccustomed to such navigation, throwing on just as much fuel as was sufficient for the purpose, and keeping clear of steeples and chimneys until they alighted in safety beyond the Boulevards. Their voyage lasted about half-an-hour, and they described a track of six miles around Paris, having ascended to a height of 3000 feet. Thus was the first balloon voyage successfully accomplished by the French; and the Montgolfiers, besides enjoying the triumph which their persevering efforts deserved, were awarded the annual prize--six hundred livres--of the Academy of Sciences. The elder brother was invited to Court, decorated with the badge of Saint Michael, and received a patent of nobility; while the younger received a pension and a sum of forty thousand livres wherewith to prosecute his experiments with balloons.
