The cheery greetings were exchanged between fellow-officers as if the game were not with death, but with racquets on an English lawn. "They are strafing a bit up there," said one; which meant that there was some shelling in the front line, where little mirrors were set up on parapets of sandbags. Through these bits of glass you could look out on a field of weeds across to another line of sandbags, Britain burrowing on one side and Germany on the other of No Man's Land. Phil took the place of another lieutenant at the O.P., or Observation Post. Here he was in touch by telephone with his battery. He watched black bursts of smoke, which were the shells from its guns, and reported their proximity to the target. It was a matter of eyesight and judgment and speaking into a black disk--nothing dramatic about it. Since he was at Mervaux he had learned much about those bursts of black smoke. He had seen many men knocked over by them. One monster had come even closer to him than the shell which had exploded between him and Helen, and on that occasion he had been dug out from under a tumbled parapet with a spade. When the Germans increased their shell-fire on any section of the British trenches, the British increased theirs on the Germans; then, in turn, the Germans increased theirs and the British increased theirs. Thus it happened on this particular morning, perhaps because the light was good for artillery observation. He was not looking to see what the German shells did to the British trench, but what his shells were doing to the German trench! "Right on!" He had announced the result of a shot when he heard the hurtling, growing scream of a nine-inch coming straight toward him. After that the end of all sensation; oblivion, which had come to many another man from the burst of a nine-inch whether or not he ever awoke to life in this world. After he knew not how long Phil felt some one pulling at his body, which seemed to rest under a great weight. This was all, and this only for a fleeting moment; he was uncertain whether he was in this world or the other. Then he was bumped against something and felt his hand brush the hard earth. Vaguely he reasoned that stretcher-bearers were carrying him around the traverse of a trench. A hot, moist sponge seemed pressed into his throat and something besides air was coming into his lungs and he was trying to cough it out. Utter darkness encompassed him and there was no sound.
