The negotiations between Holland and the Emperor are slow, but will probably end in peace. It is believed the Emperor will not at present push the Bavarian exchange. The Porte delays the demarcation of limits with him, and is making vigorous preparations for war. But neither will this latter be permitted to produce a war, if France can prevent it, because, wherever the Emperor is seeking to enlarge his dominions, France will present to him the point of a bayonet. But she wishes extremely for repose, and has need of it. She is the wealthiest but worst governed country on earth; and her finances utterly unprepared for war. We have need to pray for her repose, and that she may not be engaged in a continental war while our matters with Great Britain are so unsettled and so little like being settled. An accident has happened here which will probably damp the ardor with which aërial navigation has been pursued. Monsieur Pilatre de Roziere had been attending many months at Boulogne a fair wind to cross the channel in a balloon which was compounded of one of inflammable air, and another called a Montgolfier with rarefied air only. He at length thought the wind fair and with a companion ascended. After proceeding a proper direction about two leagues, the wind changed and brought them again over the French coast. Being at the height of about six thousand feet, some accident, unknown, burst the balloon of inflammable air, and the Montgolfier being unequal alone to sustain their weight, they precipitated from that height to the earth, and were crushed to atoms. Though navigation by water is attended with frequent accidents, and in its infancy must have been attended with more, yet these are now so familiar that we think little of them, while that which has signalized the two first martyrs to the aëronautical art will probably deter very many from the experiments they would have been disposed to make. Will you give me leave to hope the pleasure of hearing from you sometimes. The details from my own country of the proceedings of the legislative, executive and judiciary bodies, and even those which respect individuals only, are the most pleasing treat we can receive at this distance, and the most useful also. I will promise in return whatever may be interesting to you here. I am, with very perfect esteem, Sir, Your friend and servant. TO CHARLES THOMPSON. PARIS, June 21, 1785.
