鈥楾heir sons I cannot recall, except as the genial and trusty friends of later life. But the five daughters of the house none of us who enjoyed their unselfish kindness at all stages of our youth can ever forget. [31] 鈥業s not this a funny little glimpse of life?... I doubt myself that there is much use in Conferences, except that it is nice that some dear workers should meet and know each other. We had many very choice ones.鈥? � I hope, said Mrs. Thimbleby, timidly, before leaving the room, "that the Lord will soften your daughter-in-law's heart to you in this trouble." Hallelujah! Victory!鈥? 日本一本道高清无码AV,最新高清无码专区.在线观看中文字幕DVD播放 Leave that to him. Afford it? Pshaw! No, thank you. 鈥橳was he who basely did betray my husband. Later experiments proved that the biplane type of glider gave better results than the rather cumbrous model consisting of five tiers of planes. Longer and more numerous glides, to the number of seven to eight hundred, were obtained, the rate of descent being112 about one in six. The longest distance traversed was about 120 yards, but Chanute had dreams of starting from a hill about 200 feet high, which would have given him gliding flights of 1,200 feet. He remarked that 鈥業n consequence of the speed gained by running, the initial stage of the flight is nearly horizontal, and it is thrilling to see the operator pass from thirty to forty feet overhead, steering his machine, undulating his course, and struggling with the wind-gusts which whistle through the guy wires. The automatic mechanism restores the angle of advance when compromised by variations of the breeze; but when these come from one side and tilt the apparatus, the weight has to be shifted to right the machine ... these gusts sometimes raise the machine from ten to twenty feet vertically, and sometimes they strike the apparatus from above, causing it to descend suddenly. When sailing near the ground, these vicissitudes can be counteracted by movements of the body from three to four inches; but this has to be done instantly, for neither wings nor gravity will wait on meditation. At a height of three hundred or four hundred feet the regulating mechanism would probably take care of these wind-gusts, as it does, in fact, for their minor variations. The speed of the machine is generally about seventeen miles an hour over the ground, and from twenty-two to thirty miles an hour relative to the air. Constant effort was directed to keep down the velocity, which was at times fifty-two miles an hour. This is the purpose of the starting and gliding against the wind, which thus furnishes an initial velocity without there being undue speed at the landing. The highest wind we dared to experiment in blew at thirty-one miles an hour; when the113 wind was stronger, we waited and watched the birds.鈥? Yes, ma'am.
