Leave that to him. Afford it? Pshaw! I can give you no advice as to that, Mr. Errington. You must know your own affairs better than I do. Chanute realised that experiments with models were of little use; in order to be fully instructive, these experiments should be made with a full-sized machine which carried its operator, for models seldom fly twice alike in the open air, and no relation can be gained from them of the divergent air currents which they have experienced. Chanute鈥檚 idea was that any flying machine which might be constructed must be able to operate in a wind; hence the necessity for an operator to report upon what occurred in flight, and to acquire practical experience of the work of the human factor in imitation of bird flight. From this point of view he conducted his own experiments; it must be noted that he was over sixty years of age when he began, and, being no longer sufficiently young and active to perform any but short and insignificant glides, the courage of the man becomes all the more noteworthy; he set to work to evolve the state required by the problem of stability, and without any expectation of advancing to the construction of a flying machine which might be of commercial value. His main idea was the testing of devices to secure equilibrium; for this purpose he employed assistants to carry out the practical work, where he himself was unable to supply the necessary physical energy. Yes, but it wouldn't flatter you to hear her. She speaks of you as a cruel tyrant, who has separated her from her boy. His name is Oliver, isn't it? It was with a shy feeling and rather a[117] sinking heart that Herbert presented himself at Line Wall House, the residence of the major-general commanding; but he found himself among friends even on the threshold. An orderly sergeant, one of the Duke鈥檚 Own, of course, and a former comrade, took his coat and forage cap; and the servant who ushered him into the drawing-room was also an old soldier of the regiment disguised in livery, who seemed to be the herald of a triumphal procession as he threw wide the doors and with stentorian lungs announced A shabby-looking trunk and a heavy wooden box were deposited in the room before sunset. 天天看电影-天天看高清影视在线 The tears came into her eyes. She turned her head away. "Do you really care whether I am ill or well?" she asked. In spite, however, of the whitewashing of the monoplane by the Government Committee just mentioned, considerable stir was occasioned later in the year by the decision of the War Office not to order any more monoplanes; and from this time forward until the War300 period the British Army was provided exclusively with biplanes. Even prior to this the popularity of the monoplane had begun to wane. At the Olympia Aero Show in March, 1913, biplanes for the first time outnumbered the 鈥榮ingle-deckers鈥?(as the Germans call monoplanes); which had the effect of reducing the wing-loading. In the case of the biplanes exhibited this averaged about 4? lbs. per square foot, while in the case of the monoplanes in the same exhibition the lowest was 5? lbs., and the highest over 8? lbs. per square foot of area. It may here be mentioned that it was not until the War period that the importance of loading per horse-power was recognised as the true criterion of aeroplane efficiency, far greater interest being displayed in the amount of weight borne per unit area of wing. Should we, ma'am? Colonel Disney took the thing on his plate, and sat frowning at it, while a bustle at the door and a marked rise in the temperature indicated the entrance of the pi猫ce de resistance, in the shape of a well-kept saddle of mutton. Oliver did not reply.
