The balloons were made of a strong but light Lyons silk, coated with gutta percha.
It is easy to comprehend that the balloon --that marvellous vehicle which was to convey him through the air--was the constant object of his solicitude.
At the outset, in order not to give the balloon too ponderous dimensions, he had decided to fill it with hydrogen gas, which is fourteen and a half times lighter than common air.
The doctor, according to very accurate calculations, found that, including the articles indispensable to his journey and his apparatus, he should have to carry a weight of 4,000 pounds; therefore he had to find out what would be the ascensional force of a balloon capable of raising such a weight, and, consequently, what would be its capacity.
Above him was the throat of the balloon bunched and tied together, but with an open lumen through which,Bert could peer up into a vast, empty, quiet interior, and out of which descended two fine cords of unknown import, one white, one crimson, to pockets below the ring.
On the crimson padded seat of the balloon there lay a couple of rugs and a Kodak, and in opposite corners of the bottom of the car were an empty champagne bottle and a glass.
But for that little hitch the ripping-cord would have torn the balloon open as though it had been slashed by a sword, and hurled Mr.
The car of the balloon was small and neat, some bags of ballast the untidiest of its contents, and he had found a light folding-table and put it at his elbow, and on that was a glass with champagne.
Now, if you will help me sew the silk together, we will begin to work on our balloon.
First there was a strip of light green silk, then a strip of dark green and then a strip of emerald green; for Oz had a fancy to make the balloon in different shades of the color about them.
Then Oz painted it on the inside with a coat of thin glue, to make it airtight, after which he announced that the balloon was ready.
So he sent the soldier with the green whiskers for a big clothes basket, which he fastened with many ropes to the bottom of the balloon.
Monck Mason (whose voyage from Dover to Weilburg in the balloon, "Nassau," occasioned so much excitement in 1837,) conceived the idea of employing the principle of the Archimedean screw for the purpose of propulsion through the air - rightly attributing the failure of Mr.
Beneath the centre of the balloon, was a frame of light wood, about nine feet long, and rigged on to the balloon itself with a network in the customary manner.
It could be turned flat, and directed upwards or downwards, as well as to the right or left ; and thus enabled the æronaut to transfer the resistance of the air which in an inclined position it must generate in its passage, to any side upon which he might desire to act ; thus determining the balloon in the opposite direction.
