"Then we must descend." "Descend! you would not alight upon the steeples!" said the unknown, mockingly. "No; but in the environs of the city." "Well, it is too warm; let us remount a little." As he spoke thus, he seized some bags of ballast. I precipitated myself upon him; but, with one hand, he overthrew me, and the lightened balloon rose to a height of 1500 metres. "Sit down," said he, "and do not forget that Brioschi, Biot, and Gay-Lussac, ascended to a height of seven thousand metres, in order to establish some new scientific laws." "We must descend;" resumed I, with an attempt at gentleness. "The storm is gathering beneath our feet and around us; it would not be prudent." "We will ascend above it, and shall have nothing to fear from it. What more beautiful than to reign in heaven, and look down upon the clouds which hover upon the earth! Is it not an honour to navigate these aerial waves? The greatest personages have travelled like ourselves. The Marquise and Comtesse de Montalembert, the Comtesse de Potteries, Mlle. La Garde, the Marquis of Montalembert, set out from the Faubourg St. Antoine for these unknown regions. The Duc de Chartres displayed much address and presence of mind in his ascension of the 15th of July, 1784; at Lyons, the Comtes de Laurencin and de Dampierre; at Nantes, M. de Luynes; at Bordeaux, D'Arbelet des Granges; in Italy, the Chevalier Andreani; in our days, the Duke of Brunswick; have left in the air the track of their glory. In order to equal these great personages, we must ascend into the celestial regions higher than they. To approach the infinite is to comprehend it." The rarefaction of the air considerably dilated the hydrogen, and I saw the lower part of the aerostat, designedly left empty, become by degrees inflated, rendering the opening of the valve indispensable; but my fearful companion seemed determined not to allow me to direct our movements. I resolved to pull secretly the cord attached to the valve, while he was talking with animation. I feared to guess with whom I had to do; it would have been too horrible! It was about three-quarters of an hour since we had left Frankfort, and from the south thick clouds were arising and threatening to engulf us. "Have you lost all hope of making your plans succeed?" said I, with great apparent interest. "All hope!" replied the unknown, despairingly. "Wounded by refusals, caricatures, those blows with the foot of an ass, have finished me. It is the eternal punishment reserved for innovators. See these caricatures of every age with which my portfolio is filled." I had secured the cord of the valve, and stooping over his works, concealed my movements from him. It was to be feared, nevertheless, that he would notice that rushing sound, like a waterfall, which the gas produces in escaping.
