鈥楽uch may be the outline of the task鈥攁 task presented imperiously to French balloonists by the events of 1870-1, and which all the devotion and science of the Tissandier brothers failed to accomplish. To-day the problem may be set with better hope of success. All the essential difficulties may be revived by the marking out of a hostile zone around the town that must be entered; from beyond the outer edge of this zone, then, the airship will rise and take its flight鈥攁cross it. I was worried, and did not wish to meet people and be chattered to. I thought the meadow-path would be quiet, and so it was. Don't be outraged, Daddy. I am not intimating that the John Grier 彩票怎么选号码比较容易中 I was worried, and did not wish to meet people and be chattered to. I thought the meadow-path would be quiet, and so it was. Sophia. [Aside.] Monster! Man鈥檚 muscles, said da Vinci, are fully sufficient to enable him to fly, for the larger birds, he noted, employ but a small part of their strength in keeping themselves afloat in the air鈥攂y this theory he attempted to encourage experiment, just as, when his time came, Borelli reached the opposite conclusion and discouraged it. That Borelli was right鈥攕o far鈥攁nd da Vinci wrong, detracts not at all from the repute of the earlier19 investigator, who had but the resources of his age to support investigations conducted in the spirit of ages after. 鈥業n September and October, 1902, nearly 1,000 gliding flights were made, several of which covered distances of over 600 feet. Some, made against a wind of 36 miles an hour, gave proof of the effectiveness of the devices for control. With this machine, in the autumn of 1903, we made a number of flights in which we remained in the air for over a minute, often soaring for a considerable time in one spot, without any descent at all. Little wonder that our unscientific assistant should think the only thing needed to keep it indefinitely in the air would be a coat of feathers to make it light!鈥? The legends of the dawn of history, however, distribute the power of flight with less of prejudice. Egyptian sculpture gives the figure of winged men; the British Museum has made the winged Assyrian bulls familiar to many, and both the cuneiform records of Assyria and the hieroglyphs of Egypt record flights that in reality were never made. The desire fathered the story then, and until Clement Ader either hopped with his Avion, as is persisted by his critics, or flew, as is claimed by his friends. chaperoning a party of girls. He knows about you, Daddy. That is, I am not going to let them have any cares until they grow up. Two brothers, Albert and Gaston Tissandier, were338 next to enter the field of dirigible construction; they had experimented with balloons during the Franco-Prussian War, and had attempted to get into Paris by balloon during the siege, but it was not until 1882 that they produced their dirigible. I was worried, and did not wish to meet people and be chattered to. I thought the meadow-path would be quiet, and so it was. Just as records were made abroad, with one exception, so were the really efficient engines. In England there was the Green engine, but the outbreak of war found the Royal Flying Corps with 80 horse-power Gnomes, 70 horse-power Renaults, and one or two Antoinette motors, but not one British, while the Royal Naval Air Service had got 20 machines with engines of similar origin, mainly land planes in which the wheeled undercarriages had been replaced by floats. France led in development, and there is no doubt that at the outbreak of war, the French military aeroplane service was the best in the world. It was mainly composed of Maurice Farman two-seater biplanes and Bleriot monoplanes鈥攖he latter type banned for a period on account of a number of serious accidents that took place in 1912.
