There was a pleasant alternation of firelight and shadow in the long double room, the flames leaping up every now and then, and lighting wall and bookcase, picture and bust, the blue and red of the Mandarin jars, and the golden storks on the black Japanese screen; but it was such a capricious light that it did not show Allegra some one sitting perdu in Martin Disney's deep elbow chair, a person who sat and watched her with an admiring smile, as she flung off her little felt hat and fur cape, and stretched her arms above her[Pg 210] head in sheer weariness, a graceful, picturesque figure, in her plain brown serge gown, belted round the supple waist, and clasped at the throat, like Enid's, and with never an ornament except the oxydized silver clasps, and the serviceable chatelaine hanging at her side. Of the unsupported myths鈥攗nsupported, that is, by even a shadow of probability鈥攖here is no end. Although Latin legend approaches nearer to fact than the Greek in some cases, in others it shows a disregard for possibilities which renders it of far less account. Thus Diodorus of Sicily relates that one Abaris travelled round the world on an arrow of gold, and Cassiodorus and Glycas and their like told of mechanical birds that flew and sang and even laid eggs. More credible is the story of Aulus Gellius, who in his Attic Nights tells how Archytas, four centuries prior to the opening of the Christian era, made a wooden pigeon that actually flew by means of a mechanism of balancing weights and the breath of a mysterious spirit hidden within it. There may yet arise one credulous enough to state that the mysterious spirit was precursor of the internal combustion engine, but, however that may be, the pigeon of Archytas almost certainly existed, and perhaps it actually glided or flew for short distances鈥攐r else Aulus Gellius was an utter liar, like Cassiodorus and8 his fellows. In far later times a certain John Muller, better known as Regiomontanus, is stated to have made an artificial eagle which accompanied Charles V. on his entry to and exit from Nuremberg, flying above the royal procession. But, since Muller died in 1436 and Charles was born in 1500, Muller may be ruled out from among the pioneers of mechanical flight, and it may be concluded that the historian of this event got slightly mixed in his dates. I shall prove it by Mrs. Conrad herself. The development of the aeroplane between 1912 and 1914 can be judged by comparison of the requirements of the British War Office in 1912 with those laid down in an official memorandum issued by the War Office in February, 1914. This latter called for a light scout aeroplane, a single-seater, with fuel capacity to admit of 300 miles range and a speed range of from 50 to 85 miles per hour. It had to be able to climb 3,500 feet in five minutes, and the engine had to be so constructed that the pilot could start it without assistance. At the same time, a heavier type of machine for reconnaissance work was called for, carrying fuel240 for a 200 mile flight with a speed range of between 35 and 60 miles per hour, carrying both pilot and observer. It was to be equipped with a wireless telegraphy set, and be capable of landing over a 30 foot vertical obstacle and coming to rest within a hundred yards鈥?distance from the obstacle in a wind of not more than 15 miles per hour. A third requirement was a heavy type of fighting aeroplane accommodating pilot and gunner with machine gun and ammunition, having a speed range of between 45 and 75 miles per hour and capable of climbing 3,500 feet in 8 minutes. It was required to carry fuel for a 300 mile flight and to give the gunner a clear field of fire in every direction up to 30 degrees on each side of the line of flight. Comparison of these specifications with those of the 1912 trials will show that although fighting, scouting, and reconnaissance types had been defined, the development of performance compared with the marvellous development of the earlier years of achieved flight was small. Wilbur Wright in a high glide, 1903. The seventeenth century, however, gives us three names, those of Borelli, Lana, and Robert Hooke, all of which take definite place in the history of flight. Borelli ranks as one of the great figures in the study of aeronautical problems, in spite of erroneous deductions through which he arrived at a purely negative conclusion with regard to the possibility of human flight. Now Oliver was strangely interested. What plan had Mr. Kenyon formed for him? Sophia. [Rushing into her arms.] O Ratty, Ratty, what a day! what an honour! what a surprise! He had gone back to her as Leander to Hero, a boy in heart and hopefulness; and what had he found in her? A placid, obedient wife, gentle almost to apathy, but with a strain of melancholy underlying all their relations which his devoted love could not conquer. My father has no money that is not his own, retorted Roland, "and that is more than鈥曗€? Dear me! why, what a splendid diamond! exclaimed Denton, as if he saw it for the first time.
