“You remember the voyage of Blanchard and Jeffries from Dover to Calais? It was magnificent! On the 7th of January, 1785, there being a north-west wind, their balloon was inflated with gas on the Dover coast. A mistake of equilibrium, just as they were ascending, forced them to throw out their ballast so that they might not go down again, and they only kept thirty pounds. It was too little; for, as the wind did not freshen, they only advanced very slowly towards the French coast. Besides, the permeability of the tissue served to reduce the inflation little by little, and in an hour and a half the aeronauts perceived that they were descending. “‘What shall we do?’ said Jeffries. “‘We are only one quarter of the way over,’ replied Blanchard, ‘and very low down. On rising, we shall perhaps meet more favourable winds.’ “‘Let us throw out the rest of the sand.’ “The balloon acquired some ascending force, but it soon began to descend again. Towards the middle of the transit the aeronauts threw over their books and tools. A quarter of an hour after, Blanchard said to Jeffries,— “‘The barometer?’ “‘It is going up! We are lost, and yet there is the French coast.’ “A loud noise was heard. “‘Has the balloon burst?’ asked Jeffries. “‘No. The loss of the gas has reduced the inflation of the lower part of the balloon. But we are still descending. We are lost! Out with everything useless!’ “Provisions, oars, and rudder were thrown into the sea. The aeronauts were only one hundred yards high. “‘We are going up again,’ said the doctor. “‘No. It is the spurt caused by the diminution of the weight, and not a ship in sight, not a bark on the horizon! To the sea with our clothing!’ “The unfortunates stripped themselves, but the balloon continued to descend. “‘Blanchard,’ said Jeffries, ‘you should have made this voyage alone; you consented to take me; I will sacrifice myself! I am going to throw myself into the water, and the balloon, relieved of my weight, will mount again.’ “‘No, no! It is frightful!’ “The balloon became less and less inflated, and as it doubled up its concavity pressed the gas against the sides, and hastened its downward course. [Illustration: The balloon became less and less inflated] “‘Adieu, my friend,” said the doctor. ‘God preserve you!’ “He was about to throw himself over, when Blanchard held him back. “‘There is one more chance,’ said he. ‘We can cut the cords which hold the car, and cling to the net! Perhaps the balloon will rise. Let us hold ourselves ready. But—the barometer is going down! The wind is freshening! We are saved!’ “The aeronauts perceived Calais. Their joy was delirious. A few moments more, and they had fallen in the forest of Guines. I do not doubt,” added the unknown, “that, under similar circumstances, you would have followed Doctor Jeffries’ example!”
