grass on dancing wheels, and firing into the sheds where the mechanics were cowering. Then he tired of this aerodrome and flew off, overtaking two German officers on horses. He dived at them and the horses bolted. He came upon a column of 200 troops on the march, and swooped above their heads with a stream of bullets until they ran into hedges and ditches. He was using a lot of ammunition, and went up into a cloud to fix another drum. Two German aeroplanes came up to search for him, and he flew to meet them and drove one down so that it crashed to earth. German soldiers gathered round it, and our fellow came down to them and fired into their crowd. A little later he flew over a passenger train and pattered bullets through its windows, and then, having no more ammunition, went home. There was a boy of eighteen in one of our aerodromes the night before the battle, and he was very glum because he was not allowed to go across the German lines next day on account of his age and inexperience. After many pleadings he came to his squadron commander at night in his pyjamas and said, "Look here, sir, can't I go?" So he was allowed to go, and set out in company with another pilot in another machine. But he soon was alone, because he missed the other man in a rain-storm. His first adventure was with a German motor-car with two officers. He gave chase, saw it turn into side roads, and followed. Then he came low and used his machine-gun. One of the officers fired an automatic pistol at him, so our boy thought that a good challenge and, leaving go of his machine-gun, pulled out his own revolver, and there was the strangest duel between a boy in the air and a man in a car. The aeroplane was fifty feet high then, but dropped to twenty just as the car pulled up outside a house. The young pilot shot past, but turned and saw the body of one officer being dragged indoors. He swooped over the house and fired his machine-gun into it, and then sent a Very-light into the car, hoping to set it on fire. Presently he was attacked by a bombardment from machine-guns, "Archies," and light rockets, so he rose high and took cover in the clouds. But it was not the last episode of his day out. He saw some infantry crossing a wooden bridge and dived at them with rapid bursts of machine-gun fire. They ran like rabbits from a shot-gun, and when he came round again he saw four or five dead lying on the bridge. From the ditches men fired at him with rifles, so he stooped low and strafed them, and then went home quite pleased with himself.
