Wrig. You forget, honoured Madam, the governess, Miss Cob, who is expected here to-morrow. In Great Britain there were a number of aeroplane constructing firms that had managed to emerge from the lean years 1912-1913 with sufficient manufacturing plant to give a hand in making up the leeway of construction when War broke out. Gradually the260 motor-car firms came in, turning their body-building departments to plane and fuselage construction, which enabled them to turn out the complete planes engined and ready for the field. The coach-building trade soon joined in and came in handy as propeller makers; big upholstering and furniture firms and scores of concerns that had never dreamed of engaging in aeroplane construction were busy on supplying the R.F.C. By 1915 hundreds of different firms were building aeroplanes and parts; by 1917 the number had increased to over 1,000, and a capital of over a million pounds for a firm that at the outbreak of War had employed a score or so of hands was by no means uncommon. Women and girls came into the work, more especially in plane construction and covering and doping, though they took their place in the engine shops and proved successful at acetylene welding and work at the lathes. It was some time before Britain was able to provide its own magnetos, for this key industry had been left in the hands of the Germans up to the outbreak of War, and the 鈥楤osch鈥?was admittedly supreme鈥攅ven now it has never been beaten, and can only be equalled, being as near perfection as is possible for a magneto. � Two letters in February to two nieces must not be passed over. In the first we have a glimpse of the dark as well as of the hopeful side:鈥? � � 五月色婷婷综合开心网 At the same time, however, though it was at the time difficult to pick out, there was very real progress being made, and, though a number of 鈥榝reak鈥?machines fell out by the wayside, the pioneer designers of those days learnt by a process of trial and error the right principles to follow and gradually succeeded in getting their ideas crystallised. The French Kolb-Danvin engine of the horizontal type, first constructed in 1905, was probably the first two-stroke cycle engine designed to be applied to the propulsion of aircraft; it never got beyond the experimental stage, although its trials gave very good results. Stepped pistons were adopted, and the charging pump at one end was used to scavenge the power cylinder at the other ends of the engine, the transfer ports being formed in the main casting. The openings of these446 ports were controlled at both ends by the pistons, and the location of the ports appears to have made it necessary to take the exhaust from the bottom of one cylinder and from the top of the other. The carburetted mixture was drawn into the scavenging cylinders, and the usual deflectors were cast on the piston heads to assist in the scavenging and to prevent the fresh gas from passing out of the exhaust ports. A great event of Charlotte鈥檚 young days was the fancy-dress ball given by her parents in the spring of 1835. The Duke of Wellington himself was present; prominent still in the minds of men as the Deliverer of Europe, only twenty years earlier, from a tyrant鈥檚 thraldom. All the young Tuckers, not to speak of their parents, were ardent admirers of the Duke. Laura, still a mere child, in her enthusiasm slipped close up behind, when the Duke was ascending the stairs, and gently abstracted a fallen hair from the shoulder of the hero, which hair she preserved ever after among her choicest treasures; and Charlotte was no whit behind Laura in this devotion. ???Adore the transient Pageant of a Day, Horatia.
