And your husband鈥攈e who so fondly loves you鈥攈e knows all, and has forgiven all? Considering the flying man as he appeared in the war period, there entered into his composition a new94 element鈥攑atriotism鈥攚hich brought about a modification of the type, or, perhaps, made it appear that certain men belonged to the type who in reality were commonplace mortals, animated, under normal conditions, by normal motives, but driven by the stress of the time to take rank with the last expression of human energy, the flying type. However that may be, what may be termed the mathematising of aeronautics has rendered the type itself evanescent; your pilot of to-day knows his craft, once he is trained, much in the manner that a driver of a motor-lorry knows his vehicle; design has been systematised, capabilities have been tabulated; camber, dihedral angle, aspect ratio, engine power, and plane surface, are business items of drawing office and machine shop; there is room for enterprise, for genius, and for skill; once and again there is room for daring, as in the first Atlantic flight. Yet that again was a thing of mathematical calculation and petrol storage, allied to a certain stark courage which may be found even in landsmen. For the ventures into the unknown, the limit of daring, the work for work鈥檚 sake, with the almost certainty that the final reward was death, we must look back to the age of the giants, the age when flying was not a business, but romance. 鈥業鈥檓 sorry I called him a cad,鈥?she said. 鈥楬e鈥檚 only a cad in his office perhaps. My dear, did you see the crocodile holding a tray for cards? What an awful house.鈥? Yes; it is now half-past eight. I have an appointment. At least鈥擨 shall be back in an hour, I have no doubt. Galien, a French monk, published a book L鈥檃rt de naviguer dans l鈥檃ir in 1757, in which it was conjectured that the air at high levels was lighter than that immediately318 over the surface of the earth. Galien proposed to bring down the upper layers of air and with them fill a vessel, which by Archimidean principle would rise through the heavier atmosphere. If one went high enough, said Galien, the air would be two thousand times as light as water, and it would be possible to construct an airship, with this light air as lifting factor, which should be as large as the town of Avignon, and carry four million passengers with their baggage. How this high air was to be obtained is matter for conjecture鈥擥alien seems to have thought in a vicious circle, in which the vessel that must rise to obtain the light air must first be filled with it in order to rise. The matter of experiment along any lines in connection with aviation is primarily one of hard cash. Throughout the whole history of flight up to the outbreak of the European war development has been handicapped on the score of finance, and, since the85 arrival of the aeroplane, both ornithopter and helicopter schools have been handicapped by this consideration. Thus serious study of the efficiency of wings in imitation of those of the living bird has not been carried to a point that might win success for this method of propulsion. Even Wilbur Wright studied this subject and propounded certain theories, while a later and possibly more scientific student, F. W. Lanchester, has also contributed empirical conclusions. Another and earlier student was Lawrence Hargrave, who made a wing-propelled model which achieved successful flight, and in 1885 was exhibited before the Royal Society of New South Wales. Hargrave called the principle on which his propeller worked that of a 鈥楾rochoided plane鈥? it was, in effect, similar to the feathering of an oar. 啪啪免费观看大全av_成片免费观看视频日本 The envelope of this dirigible was 156 feet in length, and the method of filling was that of pushing in bags, fill them with gas, and then pulling them to pieces and tearing them out of the body of the balloon. A second contemplated method of filling was by placing a linen envelope inside the aluminium casing, blowing it out with air, and then admitting the gas between the linen and the aluminium outer casing. This would compress the air out of the linen envelope, which was to be withdrawn when the aluminium casing had been completely filled with gas. Later he was there, and she was waltzing with him. At the last moment when he was standing before her, cool, self-possessed, as it were unconscious of that burning past, she had no more power to refuse to be his partner than the bird has to escape from the snake. She had given him her hand, and they were moving slowly, softly to the music of the soft, slow waltz. Myosotis, myosotis鈥攎ystic flower which means everlasting remembrance! Would she ever forget this night? Their last meeting鈥攕afest possible meeting-place here in the shine of the lamps鈥攊n the sight of the multitude. Here she could so easily hold him at a distance. Here she might speak to him lightly, as if she too were unconscious of the past. Here she was safe against his madness and her own weak unstable heart, which fluttered at his smallest word. [Pg 225] And yet there are still quite a number of people who persist in stating that Bleriot was the first man to fly across the Channel!
