Father, may I go upstairs to Mrs. Errington? asked Rhoda, softly; "I don't want any supper." York run, the show played to enthusiastic audiences in San Francisco and Two years later she wrote another, The Pretender; a Farce in Two Acts; respectfully dedicated to 鈥楩air Isabella, the Flower of the East.鈥?This witty and amusing little farce shall be given entire in the next chapter, as a fair example of what she was able to accomplish at the age of twenty-one. It also shows conclusively her love of fun, and the manner in which she delighted in any play upon words. Oh, I don't think it can depend upon me, Mr. Diamond, she said, speaking in a little quivering voice that was barely audible; whilst, at the same time, she hurriedly turned over the pages of "The Pilgrim's Progress" with her eyes fixed on them, although she assuredly did not see one letter. Diamond gently drew the book from her hand and took the hand in his own. When Diamond had gone, the old man sent for his daughter to come to him in the parlour. "You can take yourself off, Betty Grimshaw," said he to that respectable spinster, very unceremoniously. "You and James can bide in the kitchen till supper's ready. When it is, come and tell me." Certain American radial engines were made previous to 1914, the principal being the Albatross six-cylinder engines of 50 and 100 horse-powers. Of these the smaller size was air-cooled, with cylinders of 4鈥? inches bore and 5 inches stroke, developing the rated power at 1,230 revolutions per minute, with a weight of about 5 lbs. per horse-power. The 100 horse-power size had cylinders of 5鈥? inches bore, developing its rated power at 1,230 revolutions per minute, and weighing only 2鈥?5 lbs. per horse-power. This engine was markedly similar to the six-cylindered Anzani, having all the valves mechanically operated, and with auxiliary exhaust ports at the bottoms of the cylinders, overrun by long pistons. These Albatross engines had their cylinders arranged in two groups of three, with each427 group of three pistons operating on one of two crank pins, each 180 degrees apart. 免费的黄色网站,欧美在线,av无码,免费看片,色就色 综合偷拍区 There is no doubt that the Germans had made study of aerial military needs just as thoroughly as they had perfected their ground organisation. Thus there were 21 illuminated aircraft stations in Germany before the War, the most powerful being at Weimar, where a revolving electric flash of over 27 million candle-power was located. Practically all German aeroplane tests in the period immediately preceding the War were of a military nature, and quite a number of reliability tests were carried out just on the other side of the French frontier. Night flying and landing were standardised items in the German pilot鈥檚 course of instruction while they were still experimental in other countries, and a system of signals was arranged which rendered the instructional course as perfect as might be. A series of actual measurements of lift and drift of the machine gave astonishing results. 鈥業t appeared that the total horizontal pull of the machine, while sustaining a weight of 52 lbs., was only 8.5 lbs., which was less than had been previously estimated for head resistance of the framing alone. Making allowance for the weight carried, it appeared that the head resistance of the framing was but little more than fifty per cent of the amount which Mr Chanute had estimated as the head resistance of the framing of his machine. On the other hand, it appeared sadly deficient in lifting power as compared with the calculated lift of curved surfaces of its size ... we decided to arrange our machine for the following year so that the depth of curvature of its surfaces could be varied at will, and its covering air-proofed.鈥? No; please don't praise me, said Minnie, huskily. She was shadowed by his figure as he sat beside her, and so he did not see the tears that quivered in her eyes. After a second or two, during which she had passed her handkerchief quickly, almost stealthily, across her face, she said, "But your question, you say, has answered itself." It's not a thing to decide upon all in a moment, Rhoda, said her father. This na?ve ignoring of any pretensions on the part of her present guests to be eligible for the purposes of flirtation was not lost on Rose.
