Wilhelmina says that her grandpapa George was intolerably proud after he had attained the dignity of King of England, and that he was much disposed to look down upon her father, the King of Prussia, as occupying a very inferior position. Vexatiously he delayed signing the marriage treaty, to which he had given a verbal assent, evading the subject and presenting frivolous excuses. The reputation of the English Fred was far from good. He had attained eighteen years of age, was very unattractive in personal appearance, and extremely dissolute. George I., morose and moody, was only rendered more obstinate by being pressed. These delays exasperated Frederick William, who was far from being the meekest of men. Poor Sophie Dorothee was annoyed almost beyond endurance. Wilhelmina took the matter very coolly, for she declared that she cared nothing about her cousin Fred, and that she had no wish to marry him. The rapid growth of aerial effort rendered it necessary in January of 1915 to organise the Royal Flying Corps into separate wings, and in October of the same year it was constituted in Brigades. In 1916 the Air Board was formed, mainly with the object of co-ordinating effort and ensuring both to the R.N.A.S. and to the R.F.C. adequate supplies of material as far as construction admitted. Under the presidency of Lord Cowdray, the Air Board brought about certain reforms early in 1917, and in November of that year a separate Air Ministry was constituted, separating the Air Force from both Navy and Army, and rendering it an independent force. On April 1st, 1918, the Royal Air Force came into existence, and unkind critics in the Royal Flying Corps remarked on the appropriateness of the date. At the end of the War, the personnel of the Royal Air Force amounted to 27,906 officers, and 263,842 other ranks. Contrast of these figures with the number of officers and men who took the field in 1914 is indicative of the magnitude of British aerial effort in the War period. In 1747 Marshal Saxe visited Potsdam. He witnessed a review of the guards. In the account of this review given by Algarotti, he says, 鈥淭he squadron of guards, which at one time, drawn up close, exhibited the appearance of a rock, at another resembled a cloud scattered along the plain. In the charge on full gallop one horse鈥檚 head was not a foot beyond another. The line was so exactly straight that Euclid himself could not have found fault with it.鈥? 北京赛车拉手网 The rapid growth of aerial effort rendered it necessary in January of 1915 to organise the Royal Flying Corps into separate wings, and in October of the same year it was constituted in Brigades.

George Ludwig, Count of Berg, who at this time was Bishop of Liege, was a feeble old man, tottering beneath the infirmities of eighty-two years. He did not venture upon physical resistance to the power of Prussia, but confined himself to protests, remonstrances, and to the continued exercise of his own governmental authority. As Herstal was many leagues distant from Berlin, was of comparatively little value, and could only be reached by traversing foreign states, Frederick William offered to sell all his claims to it for about eighty thousand dollars. The proposal not being either accepted or rejected by the bishop, the king, anxious to settle the question before his death, sent an embassador to Liege, with full powers to arrange the difficulty by treaty. For three days the embassador endeavored in vain to obtain an audience. He then returned indignantly to Berlin. The king, of course, regarded this treatment as an insult. The bishop subsequently averred that the audience was prevented by his own sickness. Such was the posture of affairs when Frederick William died. [The others kneel.] Oh, I knew you had a rendezvous. � � In England, the first vertical aero engine of note was that designed by Green, the cylinder dimensions being 4.15 inch diameter by 4.75 stroke鈥攁 fairly complete idea of this engine can be obtained from the accompanying diagrams. At a speed of 1,160 revolutions per minute it developed 35 brake horse-power, and by accelerating up to 1,220 revolutions per minute a maximum of 40 brake horse-power could be obtained鈥攖he first-mentioned was the rated working speed of the engine for continuous runs. A flywheel, weighing 23.5 lbs., was fitted to the engine, and this, together with the ignition system, brought the weight up to 188 lbs., giving 5.4 lbs. per horse-power. In comparison with the engine fitted to the Wrights鈥?aeroplane a greater power was obtained from approximately the same cylinder volume, and an appreciable saving in weight had also been effected. The illustration shows the arrangement of the vertical valves at the top of the cylinder and the overhead cam shaft, while the position of the carburettor and inlet pipes can be also seen. The water jackets were formed by thin copper casings, each cylinder being separate and having its independent jacket rigidly fastened to the cylinder at the top only, thus allowing for free expansion of the casing; the joint at the bottom end was formed by sliding the jacket over a rubber ring. Each cylinder was bolted to the crank-case and set out of line with the crankshaft, so that the crank has passed over the upper dead centre by the time that the piston is at the top of its stroke when receiving the full force of fuel explosion. The advantage of this desaxe setting is that the pressure in398 the cylinder acts on the crank-pin with a more effective leverage during that part of the stroke when that pressure is highest, and in addition the side pressure of the piston on the cylinder wall, due to the thrust of the connecting rod, is reduced. Possibly the charging of the cylinder is also more complete by this arrangement, owing to the slower movement of the piston at the bottom of its stroke allowing time for an increased charge of mixture to enter the cylinder. In very rapid march, the troops advanced through Grünberg toward Glogau, about forty miles in the interior. Here there was a fortified town, which was considered the key of Northern Silesia. It was but feebly garrisoned, and was entirely unprepared for resistance. By great exertions, the Austrian governor of the province, Count Wallis, and his second in command, General Browne, succeeded in placing behind the works a little garrison of one thousand men. The whole population was summoned to work upon the ramparts. Count Wallis remained in Glogau. General Browne took command of the troops and garrisons abroad. But there was a division of sentiment within the walls. Quite a large portion of the population was Protestant, and would be glad to come under the protection of Protestant Prussia. The Catholics were zealous for the continued reign of Austria. As soon as the Patents shall be perfected and proved it is contemplated, so far as may be found practicable, to further the great object in view a Company shall be formed but respecting which it is unnecessary to state further details, than that a preference will be given to all those persons who now subscribe, and to whom shares shall be appropriated according to the larger amount (being three times the sum to be paid by each person) contemplated to be returned as soon as the success of the Invention shall have been established, at their option, or the money paid, whereby the Subscriber will have the means of either withdrawing with a large pecuniary benefit, or by continuing his interest in the concern, lay the foundation for participating in64 the immense benefit which must follow the success of the plan. The attraction of the helicopter lies, probably, in the ease with which flight is demonstrated by means87 of models constructed on this principle, but one truism with regard to the principles of flight is that the problems change remarkably, and often unexpectedly, with the size of the machine constructed for experiment. Berriman, in a brief but very interesting manual entitled Principles of Flight, assumed that 鈥榯here is a significant dimension of which the effective area is an expression of the second power, while the weight became an expression of the third power. Then once again we have the two-thirds power law militating against the successful construction of large helicopters, on the ground that the essential weight increases disproportionately fast to the effective area. From a consideration of the structural features of propellers it is evident that this particular relationship does not apply in practice, but it seems reasonable that some such governing factor should exist as an explanation of the apparent failure of all full-sized machines that have been constructed. Among models there is nothing more strikingly successful than the toy helicopter, in which the essential weight is so small compared with the effective area.鈥?
