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. The applications did not materialise, as was only to be expected in view of the vagueness of the proposals. Colombine did some advertising, and Mr Roebuck expressed himself as unwilling to proceed further in the venture. Henson experimented with models to a certain extent, while Stringfellow looked for funds for the construction of a full-sized monoplane. In November of 1843 he suggested that he and Henson should construct a large model out of their own funds. On Henson鈥檚 suggestion Colombine and Marriott were bought out as regards the original patent, and Stringfellow and Henson entered into an agreement and set to work. � Well, my dear, said Mrs. Errington to her daughter-in-law, "and if he does come 'now' you must not be jealous." Horatia. Do you think them.... These achievements meant a good deal; they proved mechanically propelled flight possible. The difference between them and such experiments as were conducted by Clement Ader, Maxim, and others, lay principally in the fact that these latter either did or did not succeed in rising into the air once, and then, either willingly or by compulsion, gave up the quest, while Langley repeated his experiments and thus attained to actual proof of the possibilities of flight. Like these others, however, he decided in 1896 that he would not138 undertake the construction of a large man-carrying machine. In addition to a multitude of actual duties, which left him practically no time available for original research, he had as an adverse factor fully ten years of disheartening difficulties in connection with his model machines. It was President McKinley who, by requesting Langley to undertake the construction and test of a machine which might finally lead to the development of a flying machine capable of being used in warfare, egged him on to his final experiment. Langley鈥檚 acceptance of the offer to construct such a machine is contained in a letter addressed from the Smithsonian Institution on December 12th, 1898, to the Board of Ordnance and Fortification of the United States War Department; this letter is of such interest as to render it worthy of reproduction:鈥? 青娱乐/黄色成人网站/久操/咪咪色情网 � "And how many die every day?" "Give my love to Aunt Belinda if she cares to have it. But I daresay she won't.鈥擟. E." The end of the War brought a pause in which the multitude of aircraft constructors found themselves faced with the possible complete stagnation of the industry, since military activities no longer demanded their services and the prospects of commercial flying were virtually nil. That great factor in commercial success, cost of plant and upkeep, had received no consideration whatever in the War period, for armies do not count cost. The types of machines that had evolved from the War were very fast, very efficient, and very expensive, although the bombers showed promise of adaptation to commercial needs, and, so far as other machines were concerned, America had already proved the possibilities of mail-carrying by maintaining a mail service even during the War period. Castalia withdrew from the table, and sat down on the little sofa and cried. Her husband looked at her across a glass of very excellent sherry, which he was just about to hold up to the light. "I think, Castalia," he said, "I really do think, that when a man is in such trouble as I am, reduced to the brink of ruin, not knowing which way to turn for a ten-pound note, struggling, striving, bothering his brains to find a way out of the confounded mess, he might expect something more cheering and encouraging from his wife than perpetual snivelling." With that he cracked a filbert with a sharp jerk of indignation. But Algernon's forte was not the minatory or impressively wrathful style of eloquence. He could hurl a sarcasm, sharp, light, and polished; but when he came to wielding such a ponderous weapon as serious reproof on moral considerations, he was apt to make a poor hand of it. It was excessively disagreeable, too, to see that woman's thin shoulders moving convulsively under her gay-coloured dress, as she sobbed with her head buried in the sofa cushions. That really must be put a stop to. So, as it appeared evident that scolding would not quench the tears, he tried coaxing. The coaxing was not so efficacious as it would have been once. Still, Castalia responded to it to the extent of endeavouring to check the sobs which still shook her frail chest and throat. "When shall you be back, Ancram?" she said, looking beseechingly at him. He answered that he hoped to be in Whitford again on Tuesday night, or Wednesday at the latest (it was then Monday), and he particularly impressed on her the necessity of telling any one who might inquire the cause of his absence, that he had been suddenly called up to town by the illness of Lord Seely. He had, in fact, said a word or two to that effect when, on his way home, he had ordered the fly, which was to carry him and his valise to the coach-office. Castalia insisted on accompanying him to the coach, despite the damp cold of the night, a proceeding which he did not much combat, since he felt it would serve to give colour to his statement to the landlord of the "Blue Bell."
