He who wishes to navigate an air-ship should first practise a good many landings in a spherical balloon—that is, if he wishes to land without breaking balloon, keel, motor, rudder, propeller, water-ballast cylinders, and fuel holders. The wind being rather strong, it was necessary to seek shelter for this last manœuvre. At the end of the plain a corner of the forest of Fontainebleau was hurrying toward us. In a few moments we had turned the extremity of the wood, sacrificing our last handful of ballast. The trees now protected us from the violence of the wind, and we cast anchor, at the same time opening wide the emergency valve for the wholesale escape of the gas.
The twofold manœuvre landed us without the least dragging. We set foot on solid ground, and stood there watching the balloon die. Stretched out in the field, it was losing the remains of its gas in convulsive agitations, like a great bird that dies in beating its wings.
After taking a dozen instantaneous photographs of the dying balloon we folded it and packed it in the basket with its netting folded alongside. The little chosen corner in which we had landed formed part of the grounds of the Chateau de la Ferrière, belonging to M. Alphonse de Rothschild. Labourers from a neighbouring field were sent for a conveyance to the village of La Ferrière itself, and half-an-hour later a brake came. Putting everything into it we set off to the railway station, which was some 4 kilometres (2½" miles) distant. There we had some work to lift the basket with its contents to the ground, as it weighed 200 kilogrammes (440 pounds). At 6.30 we were back at Paris, after a journey of 100 kilometres (more than 60 miles), and nearly two hours passed in the air.

MY "BRAZIL"—SMALLEST OF SPHERICAL BALLOONS
I liked ballooning so much that, coming back from my first trip with M. Machuron, I told him that I wanted a balloon built for myself. He liked the idea. He thought that I wanted an ordinary-sized spherical balloon, between 500 and 2000 cubic metres in volume. No one would think of making one smaller.
It is only a short time ago, but it is curious how constructors still clung to heavy materials. The smallest balloon basket had to weigh 30 kilogrammes (66 lbs.). Nothing was light—neither envelope, rigging, nor accessories.
I gave M. Machuron my ideas. He cried out against it when I told him I wanted a balloon of the lightest and toughest Japanese silk, 100 cubic metres (about 3500 cubic feet) in volume. At the works both he and M. Lachambre tried to prove to me that the thing was impossible.
