We shall see our faders." My dear Mrs. Disney, do you usually walk as if for a wager? asked a voice behind her. "I can generally get over the ground pretty fast, but it was as much as I could do to overtake you without running." While Pilcher was carrying on Lilienthal鈥檚 work in England, the great German had also a follower in America; one Octave Chanute, who, in one of the statements which he has left on the subject of his experiments acknowledges forty years鈥?interest in the problem of flight, did more to develop the glider in America than鈥攚ith the possible exception of Montgomery鈥攁ny other man. Chanute had all the practicality of an American; he began his work, so far as actual gliding was concerned, with a full-sized glider of the Lilienthal type, just before Lilienthal was killed. In a rather rare monograph, entitled Experiments in Flying, Chanute states that he found the Lilienthal glider hazardous and decided to test the value of an idea of his own; in this he followed the same general method, but reversed the principle upon which Lilienthal had depended for maintaining his equilibrium in the air. Lilienthal had shifted the weight of his body, under immovable wings, as fast and as far as the sustaining pressure varied under his surfaces; this shifting was mainly done by moving the feet, as the actions required were small except when alighting. Chanute鈥檚 idea was to have the operator remain seated in the machine in the air, and to intervene only to steer or to alight; moving mechanism was provided to adjust the wings108 automatically, in order to restore balance when necessary. "My dear Gibbs," it said鈥?I am off to town by the night mail. My wife's uncle, Lord Seely, is ill, and I must see him. I shall speak to him on your behalf, of course. The inheritance must soon fall to you, without waiting for the demise of the present holder. I shall be back on Wednesday at latest. Meanwhile, I trust implicitly to your discretion. Colonel Disney and his wife stayed in London two days; perhaps to give a colour to their sudden and in somewise unexplained journey; but Isola refused all her sister's invitations, to lunch, to drive, to dine, to go to an afternoon concert at the Albert Hall, or to see the last Shakespearean revival at the Lyceum. She pleaded various excuses; and Gwendolen had to be satisfied with one visit, at afternoon teatime, when husband and wife appeared together, on the eve of their return to Cornwall. Martin Disney was full of admiration for his wife's improvements. The old-fashioned borders were brimming over with old-world flowers; the shrubberies had grown out of knowledge; the escalonia hedge by the kitchen garden was a thing to wonder at. 国内偷拍国内精品视频_2019最新欧美AV片高清观看_亚洲成在人线免费视频&#,亚洲av,香蕉视频一级在线播放 The fair Belinda looked at him angrily. There are assertions which young ladies make on purpose to have them controverted. 鈥榊ou are Sir Herbert Farrington, at this very moment.鈥? Mimie came shyly forward when she was called to add her welcome to the brother she had almost forgotten. But she[205] offered him her cheek quite naturally, and received a sister鈥檚 salute, which, nevertheless, sent the warm blood tingling through her veins. Among the first internal combustion engines to be taken into use with aircraft were those of the horizontally-opposed four-stroke cycle type, and, in every case in which these engines were used, their excellent balance and extremely even torque rendered them ideal鈥攗ntil the tremendous increase in power requirements rendered the type too long and bulky for placing in the fuselage of an aeroplane. As power increased, there came a tendency toward placing cylinders radially round a central crankshaft, and, as in the case of the early Anzani, it may be said that the radial engine grew out of the horizontal opposed piston type. There were, in 1910鈥攖hat is, in the early days of small power units, ten different sizes of the horizontally opposed engine listed for manufacture, but increase in power requirements practically ruled out the type for air work. Baynham shall talk to her this afternoon.
