The other experimenter of this period, one Count d鈥橢sterno, took out a patent in 1864 for a soaring machine which allowed for alteration of the angle of incidence of the wings in the manner that was subsequently carried out by the Wright Brothers. It was not until 1883 that any attempt was made to put this patent to practical use, and, as the inventor died while it was under construction, it was never completed. D鈥橢sterno was also responsible for the production of a work entitled Du Vol des Oiseaux, which is a very remarkable study of the flight of birds. Jack's eyes sparkled. "Good! I was wondering when you'd begin to let yourself go." He leaned forward. "You should worry! You're the prettiest girl here鈥攁nd the best dressed!" Some small mention must be made of seaplane activities, which, round the European coasts involved in the War, never ceased. The submarine campaign found in the spotting seaplane its greatest deterrent, and it is old news now how even the deeply submerged submarines were easily picked out for destruction from a height and the news wirelessed from seaplane to destroyer, while in more than one place the seaplane itself finished the task by bomb dropping. It was a seaplane that gave Admiral Beatty the news that the whole German Fleet was out before the Jutland Battle, news which led to a change of plans that very nearly brought about the destruction of Germany鈥檚 naval power. For the most part, the seaplanes of the War period were heavier than the land machines and, in the opinion of the land pilots, were slow and clumsy things to fly. This was inevitable, for their work demanded more solid building and greater reliability. To put the matter into Hibernian phrase, a forced landing at sea is a much more serious matter than on the ground. Thus255 there was need for greater engine power, bigger wing-spread to support the floats, and fuel tanks of greater capacity. The flying boats of the later War period carried considerable crews, were heavily armed, capable of withstanding very heavy weather, and carried good loads of bombs on long cruises. Their work was not all essentially seaplane work, for the R.N.A.S. was as well known as hated over the German airship sheds in Belgium and along the Flanders coast. As regards other theatres of War, they rendered valuable service from the Dardanelles to the Rufiji River, at this latter place forming a principal factor in the destruction of the cruiser K?nigsberg. Their spotting work at the Dardanelles for the battleships was responsible for direct hits from 15 in. guns on invisible targets at ranges of over 12,000 yards. Seaplane pilots were bombing specialists, including among their targets army headquarters, ammunition dumps, railway stations, submarines and their bases, docks, shipping in German harbours, and the German Fleet at Wilhelmshaven. Dunkirk, a British seaplane base, was a sharp thorn in the German side. 哪种彩票2元能中500万 Jack's eyes sparkled. "Good! I was wondering when you'd begin to let yourself go." He leaned forward. "You should worry! You're the prettiest girl here鈥攁nd the best dressed!" Hargrave, to diverge for a brief while from the machine to the man, was one who, although he achieved nothing worthy of special remark, contributed a great deal of painstaking work to the science of flight. He made a series of experiments with man-lifting kites in addition to making a study of flapping-wing flight. It cannot be said that he set forth any new principle; his work was mainly imitative, but at the same time by developing ideas originated in great measure by others he helped toward the solution of the problem. "Yes, isn't it?" said Jack. Minnie was inexpressibly vexed with herself to feel a hot flush covering her face. She knew it would be misconstrued, and that made her colour the more. Mrs. Algernon Errington was the first to speak. "Oh, Lord!" groaned the plump youth. "Do I have to get up?" Don't you mean to vouchsafe me an answer, Mrs. Algernon Ancram Errington? Tell me, Mr. Powell, and remember what a responsibility you have assumed before God and man in making this accusation鈥攖ell me truly whether you do not see visions鈥攆igures of men and women, that other people cannot see? Don't forms appear before your eyes and vanish again as suddenly? Have you not told your landlady, Mrs. Thimbleby, as much on many occasions? How can you dare to assert with confidence, that from the distance you say you were at, you could distinguish my face and that of my wife? All your description of her violent gestures, and kneeling on the ground, and clasping her hands鈥攄oes not that seem more like the delusions of fancy than the information of your sober senses? The British R.38 class, embodying the latest improvements in airship design outside Germany, gives a gross lift per airship of 85 tons and a net lift of about 45 tons. The capacity of the gas bags is about two and three-quarter million cubic feet, and, travelling at the rate of 45 miles per hour, the cruising range of the vessel is estimated at 8鈥? days. Six engines, each of 350 horse-power, admit of an extreme speed of 70 miles per hour if necessary. He learned that the Columbian would finish coaling during the afternoon. He arranged to have her continue to lie where she was until nine o'clock that night. Thus he could get his party aboard in this out-of-the-way spot after darkness had fallen. The Columbian was then to drop down-stream to an anchorage in the Bay, and proceed to sea next morning. Her Captain was instructed to see to the necessary clearance papers. Jack's eyes sparkled. "Good! I was wondering when you'd begin to let yourself go." He leaned forward. "You should worry! You're the prettiest girl here鈥攁nd the best dressed!" "Mr. Gyde had no personal attorneys. He was always suing and being sued, but he retained a new man for every case. Obviously he has made these arrangements on his own initiative. I expect it will be up to you and me to ferret out his properties. I will have my attorney probate the will. You had better have a lawyer to advise you. Have you any one in mind?"
