It was past mid-day when a loud peal at the bell of Ivy Lodge startled the women in the kitchen. Polly ran to the front door to open it. There stood her master, who pushed quickly into the house past her. "Is your mistress come back?" he asked almost breathlessly. At all events, Ancram does not care about her now, said Castalia, speaking in broken sentences, and twisting her watch-chain nervously backwards and forwards in her fingers. In the last section an attempt has been made to show how, during what was from the design standpoint perhaps the most critical period, order gradually became evident out of chaos, ill-considered ideas dropped out through failure to make good, and, though there was still plenty of room for improvement in details, the bulk of the aeroplanes showed a general similarity in form and conception. There was still a great deal to be learnt in finding the best form of wing section, and performances were still low; but it had become definitely possible to say that flying had emerged from the chrysalis stage and had become a science. The period which now began was one of scientific development and improvement鈥攊n performance, man?uvrability, and general airworthiness and stability.

What was his manner of working I do not know, but I should think it must have been very quick, and that he never troubled himself on the subject, except when he was seated with a pen in his hand. 67 Henson, who had spent a considerable amount of money in these experimental constructions, consoled himself for failure by venturing into matrimony; in 1849 he went to America, leaving Stringfellow to continue experimenting alone. From 1846 to 1848 Stringfellow worked on what is really an epoch-making item in the history of aeronautics鈥攖he first engine-driven aeroplane which actually flew. The machine in question had a 10 foot span, and was 2 ft. across in the widest part of the wing; the length of tail was 3 ft. 6 ins., and the span of tail in the widest part 22 ins., the total sustaining area being about 14 sq. ft. The motive power consisted of an engine with a cylinder of three-quarter inch diameter and a two-inch stroke; between this and the crank shaft was a bevelled gear giving three revolutions of the propellers to every stroke of the engine; the propellers, right and left screw, were four-bladed and 16 inches in diameter. The total weight of the model with engine was 8 lbs. Its successful flight is ascribed to the fact that Stringfellow curved the wings, giving them rigid front edges and flexible trailing edges, as suggested long before both by Da Vinci and Borelli, but never before put into practice. A visitor, who was often cordially welcomed at Dorrington by Matthew Diamond, was Miss Chubb. And the kind-hearted little spinster endured a vast amount of snubbing and patronage from her old enemy on the battle-ground of polite society鈥擬rs.
