Castalia shrugged her shoulders in undisguised scorn. "All that nonsense is nothing to the purpose," said she, throwing her head back against the cushion of the chair she sat on. Mrs. Errington opened her blue eyes to their widest extent. "Really, Castalia! 'All that nonsense!' You are not very polite." I can't undertake to go trapesing down there in this weather, exclaimed my lady. "And, besides, I wouldn't leave you just now." � Various types of kite balloon have been introduced; the original German Parseval-Siegsfield had a single air bag at the stern end, which was modified to two, three, or more lobes in later varieties, while an American experimental design attempted to do away with the attached lobes altogether by stringing out a series of small air bags, kite fashion, in rear of the main envelope. At the beginning of the War, Germany alone had kite balloons, for the authorities of the Allied armies considered that the bulk of such a vessel rendered it too conspicuous a mark to permit of its being serviceable. The Belgian arm alone possessed two which, on being put into service, were found extremely useful. The French followed by constructing kite balloons at Chalais Meudon, and then, after some months of hostilities and with the example of the Royal Naval Air Service to encourage them, the British military authorities finally took up the construction and use of kite balloons for artillery-spotting and general observation purposes. Although many were brought down by gun-fire, their uses far outweighed their disadvantages, and toward the end of the War, hardly a mile of front was without its 鈥楽ausage.鈥? One of the most successful of French pre-war dirigibles was a Clement Bayard built in 1912. In this twin propellers were placed at the front and horizontal and vertical rudders in a sort of box formation under the envelope at the stern. The envelope was stream-lined, while the car of the machine was placed well forward with horizontal controlling planes above it and immediately behind the propellers. This airship, which was named 鈥楧upuy de Lome,鈥?may be ranked as about the most successful non-rigid dirigible constructed prior to the War.

In that year they took up the problem thoroughly, studying all the aeronautical information then in print. Lilienthal鈥檚 writings formed one basis for their studies, and the work of Langley assisted in establishing in them a confidence in the possibility of a solution to the problems of mechanical flight. In 1909, at the banquet given by the Royal Aero Club to the Wright Brothers on their return to America, after the series of demonstration flights carried out by Wilbur Wright on the Continent, Wilbur paid tribute to the great pioneer work of Stringfellow, whose studies and achievements influenced his own and Orville鈥檚 early work. He pointed out how Stringfellow devised an aeroplane having two propellers and vertical and horizontal steering, and gave due place to this early pioneer of mechanical flight. The morning was brilliant, and Martin, Allegra, and Captain Hulbert set off at nine o'clock upon a long-deferred expedition to San Romolo. They would be home in good time for the eight-o'clock dinner; and Isola promised to amuse herself all day, and to be in good spirits to welcome them on their return. The man was James Maxfield, and he answered sulkily, "I don't know whether he's gone or not. You'd better inquire at the private door." � The Warden, 1855 \ 727 11 3
