As to Algernon鈥攈arassed, anxious, and doubtful of the future as he might be, he was glad that his wife was dead, and he knew that he was glad. Her death made a way out鈥攁pparently the only possible way out鈥攐f a labyrinth of troubles, and relieved Algernon from the apprehension of an exposure which it made him sick to think of. He had not meant to kill her, he said to himself. He had certainly laid no deliberate plan to do so. Had he, in truth, been the cause of her death? In the state of mind she was in, would she not have thrown herself into the river, or otherwise put an end to herself, without that touch from him which he had given, he knew not how? Minnie looked pained. They were trenching here on ground on which she had no intention of venturing farther. It formed no part of her plan to be drawn into a discussion respecting the defects and shortcomings of Algernon's wife. She was silent. This evening! CHAPTER XIII. I don't know. Go to bed. I don't want you. 鈥楴ow, there are only two ways of learning to ride a fractious horse: one is to get on him and learn by actual practice how each motion and trick may be best met; the other is to sit on a fence and watch the beast awhile, and then retire to the house and at leisure figure out the best way of overcoming his jumps and kicks. The latter system is the safer, but the former, on the whole, turns out the larger proportion of good riders. It is very much the same in learning to ride a flying machine; if you are looking for perfect safety you will do well to sit on a fence and watch the birds, but if you really wish to learn you must mount a machine and become acquainted with its tricks by actual trial. The balancing of a gliding or flying machine is very simple in theory. It merely consists in causing the centre of pressure to coincide with the centre of gravity.鈥? 超碰国产人人做人人爽 The trick flying of pre-war days soon became an262 everyday matter; Pegoud astonished the aviation world before the War by first looping the loop, but, before three years of hostilities had elapsed, looping was part of the training of practically every pilot, while the spinning nose dive, originally considered fatal, was mastered, and the tail slide, which consisted of a machine rising nose upward in the air and falling back on its tail, became one of the easiest 鈥榮tunts鈥?in the pilot鈥檚 repertoire. Inherent stability was gradually improved, and, from 1916 onward, practically every pilot could carry on with his machine-gun or camera and trust to his machine to fly itself until he was free to attend to it. There was more than one story of a machine coming safely to earth and making good landing on its own account with the pilot dead in his cock-pit. The difference between experiments with models and with full-sized machines is emphasised by Maxim鈥檚 statement to the effect that with a small apparatus for ascertaining the power required for artificial flight, an angle of incidence of one in fourteen was most advantageous, while with a large machine he found it best to132 increase his angle to one in eight in order to get the maximum lifting effect on a short run at a moderate speed. He computed the total lifting effect in the experiments which led to the accident as not less than 10,000 lbs., in which is proof that only his rail system prevented free flight. Then tell him to go to the devil! said Algernon, sharply jerking his arm away from the clerk's grasp, and walking off. With all my heart! he answered unhesitatingly. 62 Under these circumstances, it is proposed to raise an immediate sum of 锟?,000 in furtherance of the Projector鈥檚 views, and as some protection to the parties who may embark in the matter, that this is not a visionary plan for objects imperfectly considered, Mr Colombine, to whom the secret has been confided, has allowed his name to be used on the occasion, and who will if referred to corroborate this statement, and convince any inquirer of the reasonable prospects of large pecuniary results following the development of the Invention.
