Sergeant Jimmy saw another Hun taking aim at Lieutenant Morrison, who was engaged with a German officer. There was no time to warn the lieutenant, and Jimmy did the next best thing. His bayonet put the Hun out of the battle for all time, and the lieutenant, who had just defeated his opponent, turned with a look that meant much to Jimmy. There was no time for words. Guns and shells were crashing on all sides. The Germans had brought up some machine guns, and these were doing fearful execution among the Americans until the nests were located and the crews working the automatic death-dealers killed. Sergeant Blaise led in one of these raids, and he and his comrades had swept triumphantly over the place, leaving only dead Germans to tell the tale, when Jimmy suddenly felt a great blow on his head. Instantly all became black around him, and he fell. For one fearful moment the thought flashed through his mind that he was killed--that this was the end of it all. And then, as he landed with a thud on the ground, his senses seemed to come back to him. His face was wet, and something seemed to cover his eyes. He put his hand to his face as he lay on the ground, a horrible fear coming to him that his eyes had been blown out. To his great relief he found that his vision came back to him when he rubbed his hand over his eyes. And as he looked at his hand he found that it was not covered with blood, as he had feared, but with mud. A shell had exploded in a mud hole directly in front of Jimmy, and had deluged him with the mucky stuff, completely covering his face and eyes. "But I'm hit, though," he mused, as he felt his head, and this time there was blood on his hand. But it did not seem to be an alarming amount. In fact, after the first shock, Jimmy felt as though he could get up and go on fighting. But an officer, leaping over him, sensed the situation and cried: "Lie down where you are! Some one will come for you presently. We've got 'em on the run, but they may sweep this place with machine guns again. Lie still where you are!" Jimmy had sense enough to obey, and presently he became aware of the fact that the firing in his immediate neighborhood was growing less. In a few minutes it seemed to die away altogether, and it was not long after that before two men came along with a stretcher. "Here's a live one!" the leader cried, as he caught sight of Jimmy, who cautiously raised his head. "Hurt much?" the second stretcher bearer asked. "Don't know," was Jimmy's laconic answer. "Wait until I stand up and see." But as soon as he tried to get on his feet he felt so weak and dizzy that he would have fallen had not one of the men caught him. "I guess it's a first-aid station for yours, old man," was the grim comment. And Jimmy shut his eyes. When he opened them again it was to find himself lying on a sort of table, with a doctor bending over him. "How do you feel?" asked the surgeon. "Oh, sort of--sort of----" remarked Jimmy weakly.
