The Champ de Mars was guarded by troops, and the avenues were also guarded on all sides. As the day wore on an immense crowd covered the open space, and every advantageous spot in the neighborhood was crowded with people. At five o’clock the report of a cannon announced to the multitudes, and to scientific men who were posted on elevations to make observations of the great event, that the grand moment had come. The cords were withdrawn, and, to the vast delight and wonder of the crowd assembled, the balloon shot up with such rapidity that in two minutes it had ascended 488 fathoms. At this height it was lost in a cloud for an instant, and, reappearing, rose to a great height, and was again lost in higher clouds. The ascent was a splendid success. The rain that fell damped neither the balloon nor the ardor of the spectators. This balloon was 12 feet in diameter, 38 feet in circumference, and had a capacity of 943 cubic feet. The weight of the materials of which it was constructed was 25 lbs., and the force of ascension was that of 35 lbs. The fall of the balloon was caused by the expansion and consequent explosion of the hydrogen gas. This event took place some distance out in the country, close to a number of peasants, whose terror at the sight and the sound of this strange monster from the skies was beyond description. The people assembled, and two monks having told them that the burst balloon was the hide of a monstrous animal, they immediately began to assail it vigorously with stones, flails, and pitchforks. The cure of the parish was obliged to walk up to the balloon to reassure his terrified flock. They finally attached the burst envelope to a horse’s tail, and dragged it far across the fields. Many drawings and engravings of the period represent the peasants armed with pitchforks, flails, and scythes, assailing it, a dog snapping at it, a garde-champetre firing at it, a fat priest preaching at it, and a troop of young people throwing stones at the unfortunate machine. The news of this fiasco came to Paris, but too late. When search was made for the covering, scarcely a fragment could be found. A somewhat humorous result of all this was the issue of a communication from government to the people, entitled, “Warning to the People on kidnapping Air-balloons.” This document, duly signed and approved of, describes the ascents at Annonay and at Paris, explains the nature and the causes of the phenomena, and warns the people not to be alarmed when they see something like a “black moon” in the sky, nor to give way to fear, as the seeming monster is nothing more than a bag of silk filled with gas.
