鈥楬aving concluded my reading of old Russell, how can I do better than employ the interval before the arrival of the Indian letters in sitting down and writing to my fair absent sister? Colonel Sykes let me know last night that Robin would not come by this mail, which was, he says, only from Bombay, so that letters being all we must expect before Saturday fortnight, you need not hurry home on account of Robin鈥檚 return. VII KITE BALLOONS Contemporary with him was Charles Spencer, the first man to practise gliding in England. His apparatus consisted of a pair of wings with a total area of 30 sq. ft., to which a tail and body were attached. The weight of this apparatus was some 24 lbs., and, launching himself on it from a small eminence, as was done later by Lilienthal in his experiments, the inventor made flights of over 120 feet. The glider in question was exhibited at the Aeronautical Exhibition of 1868. In the spring of 1897 Pilcher took up his gliding experiments again, obtaining what was probably the best of his glides on June 19th, when he alighted after a perfectly balanced glide of over 250 yards in length, having crossed a valley at a considerable height. From his various experiments he concluded that once the machine was launched in the air an engine of, at most, 3 horse-power would suffice for the maintenance of horizontal flight, but he had to allow for the additional weight of the engine and propeller, and taking into account the comparative inefficiency of the propeller, he planned for an engine of 4 horse-power. Engine and propeller together were estimated at under 44 lbs. weight, the engine was to be fitted in front of the operator, and by means of an overhead shaft was to operate the propeller situated in rear of the wings. 1898 went by while this engine was under construction. Then in 1899 Pilcher became interested in Lawrence Hargrave鈥檚 soaring kites, with which he carried out experiments during the summer of 1899. It is believed that he intended to incorporate a number of these kites in a new machine, a triplane, of which the fragments remaining are hardly sufficient to reconstitute the complete glider. This new machine was never given a trial, for on September 30th, 1899,106 at Stamford Hall, Market Harborough, Pilcher agreed to give a demonstration of gliding flight, but owing to the unfavourable weather he decided to postpone the trial of the new machine and to experiment with the 鈥楬awk,鈥?which was intended to rise from a level field, towed by a line passing over a tackle drawn by two horses. At the first trial the machine rose easily, but the tow-line snapped when it was well clear of the ground, and the glider descended, weighed down through being sodden with rain. Pilcher resolved on a second trial, in which the glider again rose easily to about thirty feet, when one of the guy wires of the tail broke, and the tail collapsed; the machine fell to the ground, turning over, and Pilcher was unconscious when he was freed from the wreckage. 天天综合网网欲色,天天影视综合在线影院,天天影视涩香欲综合网 Caballo wanted us to dump our bags and head off immediately for food, but Barefoot Ted insistedon stripping down and padding off to the shower to sluice away the road grime. He came outscreaming. Why not? Lord Seely's face was almost lead-coloured. He pressed his hands one on each side of his head with a gesture of hopeless bewilderment.
