Charles. [Retreating. Aside.] Shall I run for my life? The seventeenth century was not to end, however, without practical experiment of a noteworthy kind in gliding flight. Among the recruits to the ranks of pioneers was a certain Besnier, a locksmith of Sabl茅, who somewhere between 1675 and 1680 constructed a glider of which a crude picture has come down to modern times. The apparatus, as will be seen, consisted of two rods with hinged flaps, and the original designer of the picture seems to have had but a small space in which to draw, since obviously the flaps must have been much larger than those shown. Besnier placed the rods on his shoulders, and worked the flaps by cords attached to his hands and feet鈥攖he flaps opened as they fell, and closed as they rose, so the device as a whole must be regarded as a sort of flapping glider. Having by experiment proved his apparatus successful,35 Besnier promptly sold it to a travelling showman of the period, and forthwith set about constructing a second set, with which he made gliding flights of considerable height and distance. Like Lilienthal, Besnier projected himself into space from some height, and then, according to the contemporary records, he was able to cross a river of considerable size before coming to earth. It does not appear that he had any imitators, or that any advantage whatever was taken of his experiments; the age was one in which he would be regarded rather as a freak exhibitor than as a serious student, and possibly, considering his origin and the sale of his first apparatus to such a client, he regarded the matter himself as more in the nature of an amusement than as a discovery. Horatia. Oh, it is not fit to receive you, Sir. The chimney tumbled in during the last gale.... 鈥業 will tell you between ourselves, for I would not trouble sweet Aunt Hamilton about anything, that, in my old age, since I have attained seventy, I have had more experience of difficulties and worries than perhaps at any other period of my long Indian career. I need not describe the worries; they are things that rub one, chafe one, make life鈥檚 burden heavier. And why are they permitted, darling? I think that they keep us in a more humble, clinging position. We cannot ask sympathy for such little things; we are pitied for some troubles; others we must keep to ourselves,鈥攖he[489] latter perhaps try us most. But the dear Saviour knows! He experienced daily trials of patience as well as great afflictions. It is good to remember this. Christ, in addition to cruel persecution from open enemies, had to bear the dulness of perception, the weakness of faith, the ambition, the tendency to quarrel, of His daily companions. If great troubles are like the burdens which expand into wings, it seems to me as if petty worries may turn into the soft, downy little feathers which line the wings. They make our wings softer for those whom we have to shelter beneath them. For as the Lord spreads His great Wing over us, He means us to spread our small ones over others.鈥? [133] Oh, Ancram! Oh, Ancram! she cried. Then with a sudden change of tone, she said, "Will you promise me one thing? Will you swear never to see Rhoda Maxfield again? If you will do that, I will鈥擨 will鈥攖ry to forgive you." 狠狠做五月深爱婷婷 Castalia! A 23X type followed on the 23 class, but by the time two ships had been completed, this was practically obsolete. The No. 31 class followed the 23X; it was built on Schutte-Lanz lines, 615 feet in length, 66 feet diameter, and a million and a half cubic feet capacity. The hull was similar to the later types of Zeppelin in shape, with a tapering stern and a bluff, rounded bow. Five cars each carrying a 250 horse-power Rolls-Royce367 engine, driving a single fixed propeller, were fitted, and on her trials R.31 performed well, especially in the matter of speed. But the experiment of constructing in wood in the Schutte-Lanz way adopted with this vessel resulted in failure eventually, and the type was abandoned. Penaud conceived this machine as driven by two propellers; alternatively these could be driven by petrol or steam-fed motor, and the centre of gravity of the machine while in flight was in the front fifth of the wings. Penaud estimated from 20 to 30 horse-power sufficient to drive this machine, weighing with pilot and passenger 2,600 lbs., through the air at a speed of 60 miles an hour, with the wings set at an angle of90 incidence of two degrees. So complete was the design that it even included instruments, consisting of an aneroid, pressure indicator, an anemometer, a compass, and a level. There, with few alterations, is the aeroplane as we know it鈥攁nd Penaud was twenty-seven when his patent was published. Two priests, Miollan and Janinet, proposed to drive balloons through the air by the forcible expulsion of the hot air in the envelope from the rear of the balloon. An opening was made about half-way up the envelope, through which the hot air was to escape, buoyancy being maintained by a pan of combustibles in the car. Unfortunately, this development of the Mongolfier type never got a trial, for those who were to be spectators of the first flight grew exasperated at successive delays, and in the end, thinking that the balloon would never rise, they destroyed it. Lord Seely started into a more upright posture, and then sank back again with a suppressed cry of pain. Algernon went on, without looking up: "Her manner has been very singular of late. She has taken to wandering about alone, and to make her wanderings as secretly as may be; she haunts the post-office in my absence, carefully informing herself beforehand whether I am in my private room or not; and if I am reported absent, she enters it, searches the drawers, and, I have the strongest reason to believe鈥攊ndeed I may say I know鈥攖hat she has tampered with a little cabinet in which I keep a few private papers, and taken letters out of it!"
