At this elevation the balloon rested in perfect equilibrium for nine minutes. It was the first time that human beings had ever been carried to an equal elevation, and the spectators were astonished to find that they could remain there without danger and without alarm. The balloon had a superb effect at this elevation; it looked down upon the whole town, and was seen from all the suburbs. Its size seemed hardly diminished in the least, though the men themselves were barely visible. By the aid of glasses, Roziers could be seen calmly and industriously making new gas. When the balloon descended the two men declared that they had not experienced the slightest inconvenience from the elevation. They received the universal applause which their zeal and courage so well deserved. The Marquis d’Arlandes, a major of infantry, afterwards went up with Roziers, and this latter experiment was as successful as the former.” Some days after these experiments the conductors of the Journal de Paris who described them, received a letter from Montgolfier, and also one from Gerond de Villette. The latter only is of interest here. Gerond de Villette says: “I found myself in the space of a quarter of a minute raised 400 feet above the surface of the earth. Here we remained six minutes. My first employment was to watch with admiration my intelligent companion. His intelligence, his courage and agility in attending to the fire, enchanted me. Turning round, I could behold the Boulevards, from the gate of St. Antoine to that of St. Martin, all covered with people, who seemed to me a flat band of flowers of various colours. Glancing at the distance, I beheld the summit of Montmartre, which seemed to me much below our level. I could easily distinguish Neuilly, St. Cloud, Sevres, Issy, Ivry, Charenton, and Choisy. At once I was convinced that this machine, though a somewhat expensive one, might be very useful in war to enable one to discover the position of the enemy, his manoeuvres, and his marches; and to announce these by signals to one’s own army. 1 believe that at sea it is equally possible to make use of this machine. These prove the usefulness of the balloon, which time will perfect for us. All that I regret is that I did not provide myself with a telescope.” Chapter IX. The First Aerial Voyage--Roziers and Arlandes. These experiments had only one aim--the application of Montgolfier’s discovery to aerial navigation. The knowledge gained in the Faubourg St. Antoine having led to the most favourable conclusions, it was resolved that a first aerial voyage should be attempted.
