Manufacture of the Green engines, in the period of the War, had standardised to the production of three types. Two of these were six-cylinder models, giving respectively 100 and 150 brake horse-power, and the third was a twelve-cylindered model rated at 275 brake horse-power. Conversation came to a dead halt here, and again Mrs Keeling, with growing resentment, took in Norah from head to foot. The seconds were beaten out sonorously by the pink clock on the chimney-piece, and at last Norah, now growing thoroughly uncomfortable in this hostile atmosphere, rose. Look here, Castalia; we had better understand one another at once. I shall begin by telling you what I have resolved upon, and what I have done, and you will then have to obey me implicitly. There must be no sort of discussion or hesitation. Come back to the house with me at once. 鈥?. That a horizontal position of the operator鈥檚 body may be assumed without excessive danger, and thus the head resistance reduced to about one-fifth that of the upright position. Charles. Mrs. Judith.

These, unlike the Germans, were not standardised, but were of many and diverse types. In order to get replacements quickly enough, the factories had to work on the designs they had, and thus for a long time after the outbreak of hostilities standardisation was an impossibility. The versatility of a Latin race in a measure compensated for this; from the outset, the Germans tried to overwhelm the French Air Force, but failed, since they had not the numerical superiority, nor鈥攖his equally a determining factor鈥攖he versatility and resource of the French pilots. They calculated on a 50 per cent superiority to ensure success; they needed more nearly 400 per cent, for the German fought to rule, avoiding risks whenever possible, and definitely instructed to save both machines and pilots wherever possible. French pilots, on the other hand, ran all the risks there were, got news of German movements, bombed the enemy, and rapidly worked up a very respectable anti-aircraft force which, whatever it may have accomplished in the way of hitting German planes, got on the German pilots鈥?nerves. 久久综合九色综合97 鈥楯ust tell Mamma that,鈥?said he, rising. 鈥楾hat鈥檚 what I want her to understand.鈥? Besnier鈥檚 Flying Apparatus. Such forerunners of the notable planes of the war period as the Martin Handasyde, the Nieuport, Sopwith, Bristol, and Farman machines, were features of the show; the Handley-Page monoplane, with a span of 32 feet over all, a length of 22 feet, and a weight of 422 lbs., bore no relation at all to the twin-engined giant which later made this firm famous. In the matter230 of engines, the principal survivals to the present day, of which this show held specimens, were the Gnome, Green, Renault air-cooled, Mercedes four-cylinder dirigible engine of 115 horse-power, and 120 horse-power Wolseley of eight cylinders for use with dirigibles. There was when War broke out no realisation on the part of the British Government of the need for encouraging the enterprise of private builders, who carried out their work entirely at their own cost. The importance of a supply of British-built engines was realised before the War, it is true, and a competition was held in which a prize of 锟?,000 was offered for the best British engine, but this awakening was so late that the R.F.C. took the field without a single British power plant. Although Germany woke up equally late to the need for home produced aeroplane engines, the experience gained in building engines for dirigibles sufficed for the production of aeroplane power plants. The Mercedes filled all requirements together with the Benz and the Maybach. There was a 225 horse-power Benz which was very popular, as were the 100 horse-power and 170 horse-power Mercedes, the last mentioned fitted to the Aviatik biplane of 1917. The Uberursel was a copy of the Gnome and supplied the need for rotary engines.
