Not by any means from conviction or submission to the imperious advice of Lady Seely, but under the yoke of stern necessity, Castalia had consented to try a young woman of the neighbourhood, "highly recommended." And this abigail, in her tight yellow gown, was the cause of Mrs. Algernon's reticence during dinner. The poor lady might, however, have spared herself this restraint, if its object were to keep her servants in the dark as to domestic disagreements; for no sooner had Lydia (that was the abigail's name) reached the kitchen, than she and Polly, the cook, began a discussion of Mr. and Mrs. Algernon Errington's private affairs, which displayed a surprising knowledge of very minute details, and an almost equally surprising power of piecing evidence together. He had learned not long previously that certain bills he had given, backed by the name of that solid capitalist, the Honourable Jack Price, had found their way into old Max's hands. This startled him considerably, for he had no reason to count on the old man's forbearance. The time was drawing nigh when the bills would become due. For subscriptions of sums of 锟?00, in furtherance of an Extraordinary Invention not at present safe to be developed by securing the necessary Patents, for which three times the sum advanced, namely, 锟?00, is conditionally guaranteed for each subscription on February 1, 1844, in case of the anticipations being realised, with the option of the subscribers being shareholders for the large amount if so desired, but not otherwise. In April of 1910, the Admiralty determined on a naval air service, and set about the production of rigid airships which should be able to compete with Zeppelins as naval scouts. The construction was entrusted to Vickers, Ltd., who set about the task at their Barrow works and built something which, when tested after a year鈥檚 work, was found incapable of lifting its own weight. This defect was remedied by a series of alterations, and meanwhile the unofficial title of 鈥楳ayfly鈥?was given to the vessel. When Algernon reached home that evening, he bade Lydia put up a few things for him into a little travelling valise; and when he met his wife at the dinner-table, he told her he should go up to London that night by the mail-coach. He explained, in answer to her surprised inquiries, lamentations, and objections, uttered in a querulous drawl, that he must get help from Lord Seely; that it was useless to write to him under the present circumstances, seeing that his wife would probably intercept the letter; and that, therefore, he had resolved to go to town himself and obtain a personal interview with Lord Seely. e欧美性情一线在线http - [日本高清视频,www ] While Pilcher was carrying on Lilienthal鈥檚 work in England, the great German had also a follower in America; one Octave Chanute, who, in one of the statements which he has left on the subject of his experiments acknowledges forty years鈥?interest in the problem of flight, did more to develop the glider in America than鈥攚ith the possible exception of Montgomery鈥攁ny other man. Chanute had all the practicality of an American; he began his work, so far as actual gliding was concerned, with a full-sized glider of the Lilienthal type, just before Lilienthal was killed. In a rather rare monograph, entitled Experiments in Flying, Chanute states that he found the Lilienthal glider hazardous and decided to test the value of an idea of his own; in this he followed the same general method, but reversed the principle upon which Lilienthal had depended for maintaining his equilibrium in the air. Lilienthal had shifted the weight of his body, under immovable wings, as fast and as far as the sustaining pressure varied under his surfaces; this shifting was mainly done by moving the feet, as the actions required were small except when alighting. Chanute鈥檚 idea was to have the operator remain seated in the machine in the air, and to intervene only to steer or to alight; moving mechanism was provided to adjust the wings108 automatically, in order to restore balance when necessary. In the last section an attempt has been made to show how, during what was from the design standpoint perhaps the most critical period, order gradually became evident out of chaos, ill-considered ideas dropped out through failure to make good, and, though there was still plenty of room for improvement in details, the bulk of the aeroplanes showed a general similarity in form and conception. There was still a great deal to be learnt in finding the best form of wing section, and performances were still low; but it had become definitely possible to say that flying had emerged from the chrysalis stage and had become a science. The period which now began was one of scientific development and improvement鈥攊n performance, man?uvrability, and general airworthiness and stability. Well, Rhoda? 鈥楾he first boiler which I made was constructed something on the Herreshof principle, but instead of having one simple pipe in one very long coil, I used a series of very small and light pipes, connected in such a manner that there was a rapid circulation through the whole鈥攖he tubes increasing in size and number as the steam was generated. I intended that there should be a pressure of about 100 lbs. more on the feed-water end of the series than on the steam end, and I believed that this difference in pressure would be sufficient to ensure a direct and positive circulation through every tube in387 the series. The first boiler was exceedingly light, but the workmanship, as far as putting the tubes together was concerned, was very bad, and it was found impossible to so adjust the supply of water as to make dry steam without overheating and destroying the tubes. Who, Rhoda? My dear Castalia, she is the very sweetest-tempered creature I ever met with in my life; and that is saying a good deal, let me tell you, for the Ancram temper was something quite special. A gift. I don't boast of it, because I believe it was simply constitutional. But such was the fact.
