Horatia. Why, Sir, I always thought them a sort of stone.... She had long renounced and repented of her proceedings of former days, and was now extremely royalist, but the daughter of Marie Antoinette was not likely to receive one who had been, if not implicated, at any rate hand-and-glove with the enemies of her mother. � � He adds, still further: Almighty God hath been pleased to make you slaves here, and to give you nothing but labor and poverty in this world, which you are obliged to submit to, as it is his will that it should be so. And think within yourselves, what a terrible thing it would be, after all your labors and sufferings in this life, to be turned into hell in the next life, and, after wearing out your bodies in service here, to go into a far worse slavery when this is over, and your poor souls be delivered over into the possession of the devil, to become his slaves forever in hell, without any hope of ever getting free from it! If, therefore, you would be God鈥檚 freemen in heaven, you must strive to be good, and serve him here on earth. Your bodies, you know, are not your own; they are at the disposal of those you belong to; but your precious souls are still your own, which nothing can take from you, if it be not your own fault. Consider well, then, that if you lose your souls by leading idle, wicked lives here, you have got nothing by it in this world, and you have lost your all in the next. For your idleness and wickedness is generally found out, and your bodies suffer for it here; and, what is far worse, if you do not repent and amend, your unhappy souls will suffer for it hereafter. 五月天开心激情网 Russia spent vast sums in the provision of machines: the giant Sikorsky biplane, carrying four 100 horse-power Argus motors, was designed by a young Russian engineer in the latter part of 1913, and in its early trials it created a world鈥檚 record by carrying seven passengers for 1 hour 54 minutes. Sikorsky also designed several smaller machines, tractor biplanes on the lines of the British B.E. type, which were very successful. These were the only home productions, and the imports consisted mainly of French aeroplanes by the hundred, which got as far as the docks and railway sidings and stayed there, while German influence and the corruption that ruined the Russian Army helped to lose the War. A few Russian aircraft factories were got into operation as hostilities proceeded, but their products were negligible, and it is not on record that Russia ever learned to manufacture a magneto. 鈥楾he planes were staid from three sets of fish-shaped masts, and rigged square and firm by flat steel rigging. The engine and boiler were put in the car to drive two screw-propellers, right and left-handed, 3 ft. in diameter, with four blades each, occupying three-quarters of the area of the circumference, set at an angle of 60 degrees. A considerable time was spent in perfecting the motive power. Compressed air was tried and abandoned. Tappets, cams, and eccentrics were all tried, to work the slide valve, to obtain the best results. The piston rod of engine passed through both ends of the cylinder, and with long connecting rods worked direct on the crank of the propellers. From memorandum of experiments still preserved the following is a copy of one: June, 27th, 1845, water 50 ozs., spirit 10 ozs., lamp lit 8.45, gauge moves 8.46, engine started 8.48 (100 lb. pressure), engine stopped 8.57, worked 9 minutes, 2,288 revolutions, average 254 per minute. No priming, 40 ozs. water consumed, propulsion (thrust of propellers), 5 lbs. 4? ozs. at commencement, steady, 4 lbs. ? oz., 57 revolutions to 1 oz. water, steam cut off one-third from beginning. I do believe it鈥攈eartily! In one respect the development during the War may perhaps have proved to be somewhat disappointing, as it might have been expected that great improvements would be effected in metal construction, leading almost to the abolition of wooden structures. Although, however, a good deal of experimental work was done which resulted in overcoming at any rate the worst of the difficulties, metal-built machines were little used (except to a certain extent in Germany) chiefly on account of the need for rapid production and the danger of delay resulting from switching over from known and311 tried methods to experimental types of construction. The Germans constructed some large machines, such as the giant Siemens-Schukhert machine, entirely of metal except for the wing covering, while the Fokker and Jünker firms about the time of the Armistice in 1918 both produced monoplanes with very deep all-metal wings (including the covering) which were entirely unstayed externally, depending for their strength on internal bracing. In Great Britain cable bracing gave place to a great extent to 鈥榮tream-line wires,鈥?which are steel rods rolled to a more or less oval section, while tie-rods were also extensively used for the internal bracing of the wings. Great developments in the economical use of material were also made in the direction of using built-up main spars for the wings and inter-plane struts; spars composed of a series of layers (or 鈥榣aminations鈥? of different pieces of wood also being used. �
