Roland felt that this had gone far enough. Why should his father talk pleasantly to Oliver, who had defied his authority the day before? If this went on, Oliver would be encouraged in his insubordination. He felt that it was necessary to revive the subject. A pause of nineteen years ensued, and then in 1886 Ader turned his mind to the development of the aeroplane, constructing a machine of bat-like form with a wing-spread of about forty-six feet, a weight of eleven hundred pounds, and a steam-power plant of between twenty and thirty horse-power driving a four-bladed tractor screw. On October 9th, 1890, the first trials of this machine were made, and it was alleged to have flown a distance of one hundred and sixty-four feet. Whatever truth there may be in the allegation, the machine was wrecked through deficient equilibrium at the end of the trial. Ader repeated the construction, and on October 14th, 1897, tried out his third machine at the122 military establishment at Satory in the presence of the French military authorities, on a circular track specially prepared for the experiment. Ader and his friends alleged that a flight of nearly a thousand feet was made; again the machine was wrecked at the end of the trial, and there Ader鈥檚 practical work may be said to have ended, since no more funds were forthcoming for the subsidy of experiments. A rather amusing claim to solving the problem of flight was made in the middle of the eighteenth century38 by one Grimaldi, a 鈥榝amous and unique Engineer鈥?who, as a matter of actual fact, spent twenty years in missionary work in India, and employed the spare time that missionary work left him in bringing his invention to a workable state. The invention is described as a 鈥榖ox which with the aid of clockwork rises in the air, and goes with such lightness and strong rapidity that it succeeds in flying a journey of seven leagues in an hour. It is made in the fashion of a bird; the wings from end to end are 25 feet in extent. The body is composed of cork, artistically joined together and well fastened with metal wire, covered with parchment and feathers. The wings are made of catgut and whalebone, and covered also with the same parchment and feathers, and each wing is folded in three seams. In the body of the machine are contained thirty wheels of unique work, with two brass globes and little chains which alternately wind up a counterpoise; with the aid of six brass vases, full of a certain quantity of quicksilver, which run in some pulleys, the machine is kept by the artist in due equilibrium and balance. By means, then, of the friction between a steel wheel adequately tempered and a very heavy and surprising piece of lodestone, the whole is kept in a regulated forward movement, given, however, a right state of the winds, since the machine cannot fly so much in totally calm weather as in stormy. This prodigious machine is directed and guided by a tail seven palmi long, which is attached to the knees and ankles of the inventor by leather straps; by stretching out his legs, either to the right or to the left, he moves the machine in whichever direction he pleases.... The machine鈥檚 flight lasts only three hours, after which the wings gradually close39 themselves, when the inventor, perceiving this, goes down gently, so as to get on his own feet, and then winds up the clockwork and gets himself ready again upon the wings for the continuation of a new flight. He himself told us that if by chance one of the wheels came off or if one of the wings broke, it is certain he would inevitably fall rapidly to the ground, and, therefore, he does not rise more than the height of a tree or two, as also he only once put himself in the risk of crossing the sea, and that was from Calais to Dover, and the same morning he arrived in London.鈥? But if it made some one else happy鈥攊f it made other people happy to see you there? Col. Yes, yes, I understand. Two years later she wrote another, The Pretender; a Farce in Two Acts; respectfully dedicated to 鈥楩air Isabella, the Flower of the East.鈥?This witty and amusing little farce shall be given entire in the next chapter, as a fair example of what she was able to accomplish at the[32] age of twenty-one. It also shows conclusively her love of fun, and the manner in which she delighted in any play upon words. 天天综合网网欲色 Oh, it's not to be a grand party, by any means. Mrs. Crowther told me she had asked the Baynhams and the Vicarage people to meet us, just in a friendly way. To see you happy. General Prioleau, like many others of his rank, had a strong affection for his old corps, a sort of sneaking regard which, although it did him all honour, led him to wish that he still commanded it, and to act very much as if he did. He was not the first general officer who, entrusted with the charge of several battalions, narrowed his interest to the one in which he had himself served. To dry-nurse the Duke鈥檚 Own on field days, to take an active share in its interior economy, to watch over its mess and all that appertained to the credit of the regiment, and generally to be as intimately associated with it as though he were still its colonel, were delights he could not forego. He was continually sending for Colonel Diggle to talk matters over, an interference which the great Cavendish resented, but was prohibited from protesting[221] against, by the rules of the service. Mrs. Diggle was not, and took full advantage of her exemption from the restrictions of military etiquette, to the extent of soundly abusing the general upon every occasion. Not that General Prioleau much cared. He did not command Mrs. Cavendish-Diggle, and directly he had made her acquaintance in her new character, he was heartily glad that he did not. In this same month of February, into which were crowded some of the most noteworthy of the closing events of the War, Charleston was evacuated as Sherman's army on its sweep northward passed back of the city. I am not sure whether the fiercer of the old Charlestonians were not more annoyed at the lack of attention paid by Sherman to the fire-eating little city in which four years back had been fired the gun that opened the War, than they would have been by an immediate and strenuous occupation. Sherman had more important matters on hand than the business of looking after the original fire-eaters. He was hurrying northward, close on the heels of Johnston, to prevent if possible the combination of Johnston's troops with Lee's army which was supposed to be retreating from Virginia. Bless you, no! She has not the very vaguest ideas of anything of the kind. When she had an allowance from her uncle for her dress, my lord used to have to come down every now and then with a supplementary sum of money to get her out of debt.
