His tone was significant, and contained a menace, but for this Mrs. Kenyon cared little. She had been blind, but she was clear-sighted now. She felt that it was her husband's object to keep her in perpetual imprisonment. Thus only could his ends be attained. When he was in the street he opened the envelope. To his amazement, it proved to contain one hundred dollars in bills! Still he might treat you well. She was silent, listening to his reproaches with a sullen dumbness, as it seemed to him, while he stood there in his agony of doubt鈥攊n his despairing love. He turned from her with a heart-broken sigh, and slowly left the room, going away he scarce knew whither, only to put himself beyond the possibility of saying hard things to her, of letting burning, branding words flash out of the devouring fire in his heart. Certain experiments detailed in his work were made to ascertain the size of the surface necessary for the support of any given weight. He accepted a truism of to-day in pointing out that in any matters connected with aerial investigation, theory and practice are as widely apart as the poles. Inclined at first to favour the helicopter principle, he finally rejected this in favour of the plane, with which he made numerous experiments. During these, he ascertained the peculiar advantages of curved surfaces, and saw the necessity of providing both vertical and horizontal rudders in order to admit of side steering as well as the control of ascent and descent, and for preserving equilibrium. He may be said to have anticipated the work of Lilienthal and Pilcher, since he constructed and experimented with a fixed surface glider. 鈥業t was beautiful,鈥?he wrote concerning this, 鈥榯o see this noble white bird sailing majestically from the top of a hill to any given point of the plain below it with perfect steadiness and safety, according to the set of its rudder, merely by its own weight, descending at an angle of about eight degrees with the horizon.鈥? The records quoted for 1911 form the best evidence that can be given of advance in design and performance during the year. It will be seen that the days of the giants were over; design was becoming more and more standardised and aviation not so much a matter of individual courage and even daring, as of the reliability of the machine and its engine. This was the first year in which the twin-engined aeroplane made its appearance, and it was the year, too, in which flying may be said to have grown so common that the 鈥榤eetings鈥?which began with Rheims were hardly worth holding, owing to the fact that increase in height and distance flown rendered it no longer necessary for a would-be spectator of a flight to pay half a crown and enter an enclosure. Henceforth, flying as a spectacle was very little to be considered; its commercial aspects were talked of, and to a very slight degree exploited, but, more and more, the fact that the aeroplane was primarily an engine of war, and the growing German menace against the peace of the world combined to point the way of speediest development, and the arrangements for the British Military Trials to be held in August, 1912, showed that even the British War Office was waking up to the potentialities of this new engine of war. 久久青草视频免费院_视频大全_高清在线观看,欧美成人电影,欧美图片区 If so, Ancram, he answered, with some hauteur, "the fault must be yours. I believe I should succeed in comprehending any moderately clear and accurate statement." Barbara. Ratty! She spoke in a low soft voice, which thrilled through him. The early western harvest had been gathered in. Upland and valley in that undulating land were clothed with the tawny hue of the stubble. Here and there the plough horses were moving slowly along the red ridges on the steep hillside. No touch of frost had dulled the rich hues of the autumnal flowers, and the red carnations still glowed in every cottage garden, while the pale pink trusses of hydrangea filled all the shrubberies with beauty. A keener breath came up at eventide from the salt sea beyond Point Neptune, and wilder winds crept across the inland valleys with the on-coming of night. Summer and the swallows were gone. October, a balmy season for the most part, was at hand;[Pg 139] and there were no more tea-drinkings and afternoon gossipings in the garden at the Angler's Nest. The lamps were lighted before dinner. The evenings were spent in the old library and the new drawing-room, the new room communicating with the old one by a curtained archway, so that of a night the curtains could be drawn back and Martin Disney could sit among his books by the fireplace in the library, and yet be within conversational reach of Isola and Allegra in the drawing-room, where they had piano and table-easel, work-baskets, and occupations of all kinds. In America commercial flying had begun in May of 1918 with the mail service between Washington, Philadelphia, and New York, which proved that mail carrying is a commercial possibility, and also demonstrated the remarkable reliability of the modern aeroplane by making 102 complete flights out of a possible total of 104 in November, 1918, at a cost of 0.777 of a dollar per mile. By March of 1919 the cost per mile had gone up to 1.28 dollars; the first annual report issued at the end of May showed an efficiency of 95.6 per cent and the original six aeroplanes and engines with which the service began were still in regular use.
