It is seldom, for instance, that the balloonist gets a definite view towards Colenso, which to us is the point of greatest interest. I found that the second balloon was only used as a blind to the enemy, like a paper kite flown over birds to keep them quiet. Going up to the Manchesters' position on the top of Cæsar's Camp, I had a view of the whole country almost as good as any balloon's.
On dropping one parachute, it would first partake of the motion of the balloon, but would presently drop below, when the second parachute would be dismissed, and then an imaginary line drawn between the two bodies was supposed to betray the balloon's course.
Even if all the nitrogen's gone, the balloon's in a vacuum and won't collapse and that's about the only serious effect a puncture would have. Just a moment. We'll estimate its size by the thrust it's giving the ship," he added, and turned to Bessie. "Ask the Cow whether we're getting thrust on the ship; and if so, how much.
"I don't know," he replied, gruffly. "Well, why don't you try to find out?" I said, sharply. "It seems to me that we're resting pretty heavily on those wires." "Indeed?" "Yes." I glanced out at the balloon canopy. "Great Scott, Hawkins, the balloon's leaking!" "Eh? What?" he cried, suddenly galvanized into action. "Where, Griggs, where?" "I don't know. But that's what is happening.
During its descent it partakes of the balloon's motion, and until it reaches the earth is always seen perpendicularly below the car." An interesting phenomenon, relating to the formation of fog was witnessed by M. Flammarion in one of his voyages.
Thus, subsequently, when from diminution of gas the balloon's shape elongated, the valve line would become strained and begin to open the valve, but in such a gradual manner as to escape the notice of the aeronaut. Miss Stocks, far from being unnerved by the terrible experience, actually made three subsequent ascents in company with Mr. Green.
This is substantially true, but it must be taken in connection with other facts which have a far greater influence on a balloon's position or motion.
To add to the difficulty, the balloon's inclined position did not permit of operating the valve, except on the hoop. At the request of his brother, Jules Godard attempted the difficult work of climbing to this hoop, and, in spite of his known agility, he was obliged several times to renew the effort.
At first they went down at the tremendous rate of twenty miles an hour, but after descending three miles in nine minutes, the balloon's progress was checked, and they finally alighted safely in a grass field, where their appearance so terrified the country folk that it required a good deal of coaxing in plain English to convince them that the aeronauts were not inhabitants of another world!
In daytime the sun's influence is an all-important factor, and whether shining brightly or partially hidden by clouds, a slight difference in obscuration will have a ready and marked effect on the balloon's altitude.
