The pamphlet begins with Walker鈥檚 admiration of the mechanism of flight as displayed by birds. 鈥業t is now almost twenty years,鈥?he says, 鈥榮ince I was first led to think, by the study of birds and their means of flying, that if an artificial machine were formed with wings in exact imitation of the mechanism of one of those beautiful living machines, and applied in the very same way upon the air, there could be no doubt of its being made to fly, for it is an axiom in philosophy that the same cause will ever produce the same effect.鈥?With this he confesses his inability to produce the said effect through lack of funds, though he clothes this delicately in the phrase 鈥榩rofessional avocations50 and other circumstances.鈥?Owing to this inability he published his designs that others might take advantage of them, prefacing his own researches with a list of the very early pioneers, and giving special mention to Friar Bacon, Bishop Wilkins, and the Portuguese friar, De Guzman. But, although he seems to suggest that others should avail themselves of his theoretical knowledge, there is a curious incompleteness about the designs accompanying his work, and about the work itself, which seems to suggest that he had more knowledge to impart than he chose to make public鈥攐r else that he came very near to complete solution of the problem of flight, and stayed on the threshold without knowing it. I was very sorry to hear him talk in this way; for whatever strength a man may have he should surely be able to make more of it if he act in concert than alone. I said this. "It is a simple fracture, but it will have to be set, and it will need a strong man to do it. You can get a splint while I make the bandages. There now," she said, "take hold of the hand and pull it slowly and steadily鈥攖his way鈥攕ee. Now, are you ready?" 星空彩票_让中奖更简单 I was very sorry to hear him talk in this way; for whatever strength a man may have he should surely be able to make more of it if he act in concert than alone. I said this. Apart from these two experimenters, there is little to record in the matter either of experiment or study until the seventeenth century. Francis Bacon, it is true, wrote about flying in his Sylva Sylvarum, and mentioned the subject in the New Atlantis, but, except for the insight that he showed even in superficial mention of any specific subject, he does not appear to have made attempt at serious investigation. 鈥楽preading of21 Feathers, thin and close and in great breadth will likewise bear up a great Weight,鈥?says Francis, 鈥榖eing even laid without Tilting upon the sides.鈥?But a lesser genius could have told as much, even in that age, and though the great Sir Francis is sometimes adduced as one of the early students of the problems of flight, his writings will not sustain the reputation. 196 Geoffrey de Havilland, though of later rank, counts high among designers of British machines. He qualified for his brevet as late as February, 1911, on a biplane of his own construction, and became responsible for the design of the BE2, the first successful British Government biplane. On this he made a British height record of 10,500 feet over Salisbury Plain, in August of 1912, when he took up Major Sykes as passenger. In the war period he was one of the principal designers of fighting and reconnaissance machines. 鈥淗ow can I tell?鈥?replied Martin. 鈥淲ith Corinna all things are possible.鈥? Chapter 42 鈥淲hy, Ellen,鈥?said he, 鈥渨hat nonsense you talk; you haven鈥檛 been in prison, have you?鈥? Charles. You know all? Lord Seely stared at the florid, fat, unfeeling face before him, with a sensation of oppression and dismay. How was it possible to attribute such actions and motives to persons of one's own family with an air of such matter-of-fact indifference? It was not the first time that his wife's coarseness of feeling had been thrust on his observation to the shocking of his own finer taste and sentiment鈥攆or my lord was a gentleman at heart鈥攂ut this was an amount of phlegmatic cynicism which hurt him to the core. He could not forget that it was his wife who had promoted the marriage of Castalia with this young man. It was his wife who had declared that the Honourable Miss Kilfinane was not likely to make a better match. It was his wife who had urged him to put young Errington into the Whitford Post-office, declaring that the place was in every way a suitable one for him. And now it was his wife who coolly described Ancram as a wretch, full of the vilest duplicity! "My dear Algernon,鈥擨 want to say a word to you quietly. Can you come to me on your way home this afternoon? I will be ready to receive you at any hour between four and six. Don't disappoint your old friend, I was very sorry to hear him talk in this way; for whatever strength a man may have he should surely be able to make more of it if he act in concert than alone. I said this. She now saw this, and hastened back along the road, in a tremor at her narrow escape; for, although the impulse had crossed her mind to declare herself, and boldly enter Maxfield's house in quest of her husband, that was a very different matter from being suddenly discovered against her will. In the latter case she would, as she well knew, have been at an immense disadvantage with her husband, who, instead of being accused, would become accuser.
