He is at home, replied Castalia, slowly. "I asked him to come into the drawing-room, and he said he would by-and-by." Horatia. 鈥橳is old Colonel Stumply. Still she did not move.

The radial type of engine, neglected altogether in Germany, was brought to a very high state of prefection at the end of the War period by British makers.

You can close the door of that dressing-closet if you choose. But there is no one there. There was never a more enthusiastic and consistent student of the problems of flight than Otto Lilienthal, who was born in 1848 at Anklam, Pomerania, and even from his early school-days dreamed and planned the conquest of the air. His practical experiments began when, at the age of thirteen, he and his brother Gustav made wings consisting of wooden framework covered with linen, which Otto attached to his arms, and then ran downhill flapping them. In consequence of possible derision on the part of other boys, Otto confined these experiments for the most part to moonlit nights, and gained from them some idea of the resistance offered by flat surfaces to the air. It was in 1867 that the two brothers began really practical work, experimenting with wings which, from their design, indicate some knowledge of Besnier and the history of his gliding experiments; these wings the brothers fastened to their backs, moving them with their legs after the fashion of one attempting to swim. Before they had achieved any real success in gliding the Franco-German war came as an interruption; both brothers served in this campaign, resuming their experiments in 1871 at the conclusion of hostilities. It assumed, of course, a great variety of forms and colours, according to the more or less distorting mediums through which it passed. The fact, as uttered by Miss Chubb, for example, was a very different-looking fact from that which was narrated with bated breath, and nods, and winks, by Mrs. Smith, the surgeon's wife. And her version, again, varied considerably from those of Mr. Gladwish, the Methodist shoemaker; Mr. Barker, the Church of England chemist; and the bosom friends of the servants at Ivy Lodge. Still, under one shape and another, Mrs. Algernon Errington's jealousy of her husband, and her consequent behaviour, were within the cognisance of Whitford, and were discussed in all circles there. Practically all these vessels were discounted by the work of Ferdinand von Zeppelin, who set out from the first with the idea of constructing a rigid dirigible. Beginning in 1898, he built a balloon on an aluminium framework covered with linen and silk, and divided into interior compartments holding linen bags which were capable of containing nearly 400,000 cubic feet of hydrogen. The total length of this first Zeppelin airship was 420 feet and the diameter 38 feet. Two cars were rigidly attached to the envelope, each carrying a 16 horse-power motor, driving propellers which were rigidly connected to the aluminium framework of the balloon. Vertical and horizontal screws were used for lifting and forward driving and a sliding weight was used to raise or lower the stem of the vessel out of the horizontal in order to rise or descend without altering the load by loss of ballast or the lift by loss of gas.
