Reconnaissance work developed, so that fighting machines went as escort to observing squadrons and scouting operations were undertaken up to 100 miles behind the enemy lines; out of this grew the art of camouflage, when ammunition dumps were painted to resemble herds of cows, guns were screened by foliage or painted to merge into a ground scheme, and many other schemes were devised to prevent aerial observation. Troops were moved by night for the most part, owing to the keen eyes of the air pilots and the danger of bombs, though occasionally the aviator had his chance. There is one story concerning a British pilot who, on returning from a reconnaissance flight, observed a German Staff car on the road under him; he descended and bombed and machine-gunned the car until the German General and his chauffeur abandoned it, took to their heels, and ran like rabbits. Later still, when Allied air superiority was assured, there came the phase of machine-gunning bodies of enemy troops from the air. Disregarding all anti-aircraft measures, machines would sweep down and throw battalions into panic or upset the military traffic along a road, demoralising a battery or a transport254 train and causing as much damage through congestion of traffic as with their actual machine-gun fire. Aerial photography, too, became a fine art; the ordinary long focus cameras were used at the outset with automatic plate changers, but later on photographing aeroplanes had cameras of wide angle lens type built into the fuselage. These were very simply operated, one lever registering the exposure and changing the plate. In many cases, aerial photographs gave information which the human eye had missed, and it is noteworthy that photographs of ground showed when troops had marched over it, while the aerial observer was quite unable to detect the marks left by their passing. Who did you say this was? he asked. The discovery is of that peculiar nature, so simple in principle yet so perfect in all the ingredients required61 for complete and permanent success, that to promulgate it at present would wholly defeat its development by the immense competition which would ensue, and the views of the originator be entirely frustrated. Because you look so much like a certain Rupert Jones, who once flourished and forged there, that there might be trouble. I used to know Rupert Jones myself, and he did me an injury. You remember that. I have wanted to be revenged for years, but I am satisfied now. Once you were up and I was down. Now it's the other way. I am rich, and when I die, that boy鈥攑ointing to Oliver鈥?is my heir." Her face was hidden on his breast, but she lifted up her arms and clasped them round his neck. He seated himself in his accustomed chair鈥攊t was standing where it had always stood before he went away鈥攁nd took her upon his knee, as if she had been a child. Then a great storm of sobs suddenly burst from throat and bosom, a flood of tears streamed upon his breast, and he felt her arms trembling as they clasped his neck. Tired? Nay, and well you may be if you took all that round! I thought you'd happen been into Whitford. Lawk, how you're squashing your bonnet! Let me take it off for you. 加勒比一本道 日本一本道a不卡免费 一本道dvd手机在线观看 Meanwhile the great event of 1919, the crossing of the Atlantic by air, was gradually ripening to performance. In addition to the rigid airship, R.34, eight machines entered for this flight, these being a Short seaplane, Handley-Page, Martinsyde, Vickers-Vimy, and Sopwith aeroplanes, and three American flying boats, N.C.1, N.C.3, and N.C.4. The Short seaplane was the only one of the eight which proposed to make the journey westward; in flying from England to Ireland, before starting on the long trip to Newfoundland, it fell into the sea off the coast of Anglesey, and so far as it was concerned the attempt was abandoned. 鈥業s he in attendance?鈥? Some such thoughts were vaguely flitting through Diamond's mind when Rhoda raised her head, and, emboldened by the gathering dusk, looked up into his face and said, "You know it cannot be unless father consents." I am not likely to find fault with it, said Nicholas. "I've roughed it a good deal in my time, and I aint much used to luxury. If I get a comfortable bed, and good plain victuals, it's enough for me." I have heard of Florette's sickness, and I have come to help you.
