still three thousand five hundred fathoms of breathing air. Besides, do not trouble yourself about what I do."
I would have risen, but a vigorous hand held me, to my seat. "Your name?" I asked.
"My name? What matters it to you?"
"I demand your name!"
"My name is Erostratus or Empedocles, whichever you choose!"
This reply was far from reassuring. The unknown, besides, talked with with strange coolness that I anxiously asked myself whom I had to deal with.
"Monsieur," he continued, "nothing original has been imagined since the physicist Charles. Four months after the discovery of balloons, this man had invented the valve which permits the gas to escape when the balloon is too full, or when you wish to descend; the car, which aids the management of the machine; the netting, which holds the envelope of the balloon, and divides the weight over its whole surface; the ballast, which enables you to ascend, and to choose the place of your landing; the india-rubber coating, which renders the tissue impermeable; the barometer, which shows the height attained. Lastly, Charles used hydrogen, which, fourteen times lighter than air, permits you to penetrate to the highest atmospheric regions, and does not expose you to the dangers of a combustion in the air. On the 1st of December, 1783, three hundred thousand spectators were crowded around the Tuilleries. Charles rose, and the soldiers presented arms to him. He traveled nine leagues in the air, conducting his balloon with an ability not surpassed by modern aeronauts. The king awarded him a pension of two thousand livres; for then they encouraged new inventions."
The unknown now seemed to he under the influence of considerable agitation.
"See, there is Darmstadt," said he, leaning over the car. "Do you perceive the chateau? Not very distinctly, eh? What would you have? The heat of the storm makes the outline of objects waver, and you must have a skilled eye to recognize localities."
"Are you certain it is Darmstadt? I asked.
"I am sure of it. We are now six leagues from Frankfort."
"Then we must descend."
"Descend! You would not go down on the steeples," said the unknown, with a chuckle.
"No, but the suburbs of the city."
"Well, let us avoid the steeples!"
So speaking, my companion seized some bags of ballast. I hastened to prevent him; but he overthrew me with one hand, and the unballasted balloon ascended to two thousand yards.
"Rest easy," said he, "and do not forget that Brioschi, Biot, Gay-Lussac, Bixio, and Barral ascended to still greater heights to make their scientific experiments."
"Monsieur, we must descend," I resumed, trying to persuade him by gentleness. "The storm is gathering around us. It would be more prudent"
"Bah! We will mount higher than the storm, and then we shall no longer fear it!" cried my companion. "What is nobler than to overlook the clouds which oppress the earth? Is it not an honor thus to navigate on aerial billows? The greatest men have traveled as we are doing. The Marchioness and Countess de Montalembert, the Countess of Podenas, Mademoiselle la Garde, the Marquis de Montalembert, rose from the Faubourg Saint-Antoine for these unknown regions, and the Duke de Chartres exhibited much skill and presence of mind in his ascent on the 15th of July, 174. At Lyons, the Counts of Laurencin and Dampierre; at Nantes, M. de Luynes; at Bordeaux, D'Arbelet des Granges; in Italy, the Chevalier Andreani; in our own time, the Duke of Brunswick,— have all left traces of their glory in the air. To equal these great personages, we must penetrate still higher than they into the celestial depths! To approach the infinite is to comprehend it!"
The rarefaction of the air was fast expending the hydrogen in the balloon, and I saw its lower part, purposely left empty, swell out, so that it was absolutely necessary to open the valve; but my companion did not seem to intend that I should manage the balloon as I wished. I then resolved to pull the valve-cord secretly, as he was excitedly talking; for I feared to guess with whom I had to deal. It would have been too horrible! It was nearly a quarter before one. We had been gone forty minutes from Frankfort; heavy clouds were coming against the wind from the south, and seemed about to burst upon us.
"Have you lost all hope of succeeding in your project?" I asked with anxious interest.
"All hope!" exclaimed the unknown in a low voice. "Wounded by slights and caricatures, these asses' kicks have finished me! It is the eternal punishment reserved for innovators! Look at these caricatures of all periods, of which my portfolio is full."
While my companion was fumbling with his papers, I had seized the valve-cord without his perceiving it. I feared, however, that he might hear the hissing noise, like a water-course, which the gas makes in escaping.
"How many jokes were made about the Abbé Moilan! said he. "He was to go up with Janninet and Bredin. During the filling their balloon caught fire, and the ignorant populace tore it to pieces! Then this caricature of 'curious animals' appeared, giving each of them a punning nickname."
I pulled the valve-cord, and the barometer began to ascend. It was time. Some far-off rumblings were heard in the south.
"Here is another engraving," resumed the unknown, not suspecting what I was doing. "It is an immense balloon carrying a ship, strong castles, houses, and so on. The caricaturists did not suspect that their follies would one day become truths. It is complete, this large vessel. On the left is its helm, with the pilot's box; at the prow are pleasure-houses, an immense organ, and a cannon to call the attention of the inhabitants of the earth or the moon; above the poop there are the observatory and the balloon longboat; in the equatorial circle, the army barrack; on the left, the funnel; then the upper galleries for promenading, sails, pinions; below, the cafés and general storehouse. Observe this pompous announcement; 'Invented for the happiness of the human race, this globe will depart at once for the ports of the Levant, and on its return the pro-
