`Yes, sir,' `No, sir,' whenever a Trustee spoke. And the dialogue, on which the modern novelist in consulting the taste of his probable readers must depend most, has to be constrained also by other rules. The writer may tell much of his story in conversations, but he may only do so by putting such words into the mouths of his personages as persons so situated would probably use. He is not allowed for the sake of his tale to make his characters give utterance to long speeches, such as are not customarily heard from men and women. The ordinary talk of ordinary people is carried on in short, sharp, expressive sentences, which very frequently are never completed 鈥?the language of which even among educated people is often incorrect. The novel-writer in constructing his dialogue must so steer between absolute accuracy of language 鈥?which would give to his conversation an air of pedantry, and the slovenly inaccuracy of ordinary talkers, which if closely followed would offend by an appearance of grimace 鈥?as to produce upon the ear of his readers a sense of reality. If he be quite real he will seem to attempt to be funny. If he be quite correct he will seem to be unreal. And above all, let the speeches be short. No character should utter much above a dozen words at a breath 鈥?unless the writer can justify to himself a longer flood of speech by the specialty of the occasion. The one at the end accomplishing a graceful pirouette is me--I mean Why it's from Uncle Val! she exclaimed. Lots of people! Gammon! 亚洲高清有码中文字_亚洲成女人图区 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. III SIR GEORGE CAYLEY鈥擳HOMAS WALKER After the adjustments for actual flight had been made in the Curtiss factory, according to the minute descriptions contained in the Langley Memoir on Mechanical Flight, the aeroplane was taken to the shore of Lake Keuka, beside the Curtiss hangars, and assembled for launching. On a clear morning (May 28th) and in a mild breeze, the craft was lifted on to the water by a dozen men and set going, with Mr Curtiss at the steering wheel, esconced in the little boat-shaped car under the forward part of the frame. The four-winged craft, pointed somewhat across the wind, went skimming over the wavelets, then automatically headed into the wind, rose in level poise, soared gracefully for 150 feet, and landed softly on the water near the shore. Mr Curtiss asserted that he could have flown farther, but, being unused to the machine, imagined that the left wings had more resistance than the right. The truth is that the aeroplane was perfectly balanced in wing resistance, but turned on the water245 like a weather vane, owing to the lateral pressure on its big rear rudder. Hence in future experiments this rudder was made turnable about a vertical axis, as well as about the horizontal axis used by Langley. Henceforth the little vertical rudder under the frame was kept fixed and inactive.7 So signal a success in France was a sufficient guarantee of success elsewhere. A knowledge of the book must have speedily crossed the Channel, for Blackstone quoted it the very year after its publication. It was first translated into English in 1768, together with Voltaire鈥檚 commentary; but just as Morellet鈥檚 translation professed to have been published at Philadelphia, so the English translator kept his name a secret. The Economical Society of Berne, which was accustomed to bestow a gold medal on the writer of the best treatise on any given subject, violated its own rules in favour of the anonymous writer of the 鈥楧elitti,鈥?inviting him to disclose his name, and to accept the gold medal 鈥榓s a sign of esteem due to a citizen who had dared to raise his voice in favour of humanity against the most deeply engrained prejudices.鈥?
