There was a sudden hush of profound attention. David Powell still stood up in face of the assembly. He was rocking himself to and fro in a singular, restless way, and muttering under his breath very rapidly. It was observable, too, that his eyes seemed continually attracted to one point in the room just behind Algernon Errington. Every now and then he passed his hands over his eyes, as if to obliterate, or shut out, some painful sight, but he did not turn his head away; and the next instant after making that gesture, he would stare at the same point again, with an expression of intense horror. Algernon waited for an instant before speaking. Then he said in such a tone as one uses to attract the attention of a very young child, "Mr. Powell, will you try to listen to me?" Castalia! The writing of the play as a whole is unequal,鈥攚hat girl of eighteen is not unequal?鈥攂ut in these lines,as well as elsewhere, there are tokens of genuine power, alike poetical and dramatic. Rhoda looked up at him in genuine surprise; but her eyes fell before the answering look they encountered, and she blushed from brow to chin. Germany, from the outbreak of war, practically, concentrated on the development of the Mercedes engine; and it is noteworthy that, with one exception, increase of power corresponding with the increased demand for power was attained without increasing the number of cylinders. The various models ranged between 75 and 260 horse-power, the latter being the most recent production of this type. The exception to the rule was the eight-cylinder 240 horse-power, which was replaced by the 260 horse-power six-cylinder model, the latter being more reliable and but very slightly heavier. Of the other engines, the 120 horse-power Argus and the 160 and 225 horse-power Benz were the most used, the Oberursel being very largely discarded after the Fokker monoplane had had its day, and the N.A.G. and Austro-Daimler also falling to comparative disuse. It may be said that the development of the Mercedes engine contributed very largely to such success as was achieved in the war period by German aircraft, and, in developing the engine, the builders were careful to make alterations in such a way as to effect the least possible change in the design of aeroplane to which they were to be fitted. Thus the engine base of the 175 horse-power model coincided precisely with that of the 150 horse-power model, and the 200 and 240 horse-power models retained the same base dimensions. It was estimated, in 1918, that well over eighty per cent of German aircraft was engined with the Mercedes type. 超碰97免费人妻,亚洲第一成年网站视频,老司机亚洲精品视频 A rather amusing claim to solving the problem of flight was made in the middle of the eighteenth century38 by one Grimaldi, a 鈥榝amous and unique Engineer鈥?who, as a matter of actual fact, spent twenty years in missionary work in India, and employed the spare time that missionary work left him in bringing his invention to a workable state. The invention is described as a 鈥榖ox which with the aid of clockwork rises in the air, and goes with such lightness and strong rapidity that it succeeds in flying a journey of seven leagues in an hour. It is made in the fashion of a bird; the wings from end to end are 25 feet in extent. The body is composed of cork, artistically joined together and well fastened with metal wire, covered with parchment and feathers. The wings are made of catgut and whalebone, and covered also with the same parchment and feathers, and each wing is folded in three seams. In the body of the machine are contained thirty wheels of unique work, with two brass globes and little chains which alternately wind up a counterpoise; with the aid of six brass vases, full of a certain quantity of quicksilver, which run in some pulleys, the machine is kept by the artist in due equilibrium and balance. By means, then, of the friction between a steel wheel adequately tempered and a very heavy and surprising piece of lodestone, the whole is kept in a regulated forward movement, given, however, a right state of the winds, since the machine cannot fly so much in totally calm weather as in stormy. This prodigious machine is directed and guided by a tail seven palmi long, which is attached to the knees and ankles of the inventor by leather straps; by stretching out his legs, either to the right or to the left, he moves the machine in whichever direction he pleases.... The machine鈥檚 flight lasts only three hours, after which the wings gradually close39 themselves, when the inventor, perceiving this, goes down gently, so as to get on his own feet, and then winds up the clockwork and gets himself ready again upon the wings for the continuation of a new flight. He himself told us that if by chance one of the wheels came off or if one of the wings broke, it is certain he would inevitably fall rapidly to the ground, and, therefore, he does not rise more than the height of a tree or two, as also he only once put himself in the risk of crossing the sea, and that was from Calais to Dover, and the same morning he arrived in London.鈥? I trust so, Mrs. Thimbleby. His removal from the scene of life would be a terrible loss to this country. From the sovereign downwards, we should all feel it. On our way back through the temple-quarter a sudden wild excitement possessed the worshippers and priests; out of a side street rushed a large troop of monkeys, grey, with black faces. They galloped past in a close pack and fled to the trees, shrieking shrilly. One, however, lagged behind, bent on stealing some rice that had been brought as an offering to a plaster image of Vishnu. A Brahmin stood watching the monkey, and tried to scare it away with a display of threatening arms, but he dared not hit the beast sacred to Hanuman, the god of the green face. The creature, never stirring from the spot, yelled aloud, bringing the rest of the pack back on to the roof of the neighbouring pagodas. Then the ringleader, with a subdued, sleepy, innocent gait, stole gently up to the tray of offerings. He was on the point of reaching it when the priest raised his arm. This was a signal for the whole tribe to scream and dance with terror, but without retreating. The performance seemed likely to last; the bazaar and the temples were in a hubbub of excitement; the doors of the shops and the sanctuaries were hastily shut, till, at the mere sight of a man who came out[Pg 299] with a long bamboo in his hand, the whole pack made off and appeared no more, and Hardwar relapsed into its somnolent sanctity.
