diluted sulphuric acid upon iron filings. Their balloon, which was made of thin silk, varnished with a solution of elastic gum, was a much nearer approach to the balloon of modern days than that of Montgolfier. It was a great success; it rose and remained suspended at a height of 100 feet, in which state it was conveyed with acclamation to the Place des Victoires, where it rested and underwent some repairs. At midnight it was conveyed in solemn procession by torchlight, and guarded by a detachment of horse, to the Champ de Mars, where, on the following day, the whole world of Paris turned out to witness another ascent. The balloon went up to the sound of cannon, and in two minutes reached a height of 3000 feet, when it was lost for a time in a dark cloud, but speedily reappeared still higher. After a flight of fifteen miles, performed in three-quarters of an hour, it sunk to the ground in a field near Ecouen, where it was secured by the peasants.
The Parisians now appeared to become balloon-mad. The Royal Academy of Sciences invited Joseph Montgolfier to repeat his experiments, and another balloon was prepared by him of coarse linen with a paper lining, which, however, was destroyed by incessant and violent rain before it could be tried. Undeterred by this, another was constructed by him, which ascended from Versailles on the 19th of September 1783.
This balloon deserves peculiar notice as being the first which carried up living creatures. A sheep, a cockerel, and a duck, were the first aeronauts! They ascended to a height of about 1500 feet; remained suspended for a time, and descended some two miles off in perfect safety--indeed we may say in perfect comfort, for the sheep was discovered to be quietly feeding when it returned to the earth!
The practicability of ballooning being now fairly established, men soon began to venture their own persons in the frail cars. A young and enthusiastic naturalist named Rozier leaped into the car of another of Montgolfier's balloons soon after this, and ascended in safety to an elevation of about 300 feet, but on this occasion the balloon was held down by ropes. The ice, however, was broken, and bolder attempts quickly followed.
CHAPTER THREE.
EARLY ATTEMPTS AT AERIAL NAVIGATION.
The first free and unfettered balloon voyage was performed very soon after the event mentioned at the end of the last chapter. It was a daring attempt, and attended with great danger.
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
