“Ah, he got his, all righty!” Don shouted; then turning: “And here’s another who’s going to get his! Billy, this Hun, this skunk here, is praising the act of that devil! We’ll just dump him out and let him lie here and suffer and bleed to death. Come on; give a hand!” “No, no, Don! You can’t mean that. It would not be humane.” “Humane? I’d be humane to a dog, a cat, a worm even, I hope, but not to a thing like this. Come--!” “‘As they should do unto you’, Don. I know this is war and he’s a Hun, but it’s all the more of an excuse that he is only partly human; he doesn’t know any better and he has feelings, some. Let’s go on, Don, please, now.” Don leaped to his seat with Billy and they continued on their way. CHAPTER X ZEALOUS BILLY Major Little ordered the German airman turned over to an army ambulance where he would be disposed of as a wounded man and prisoner. To Don the surgeon said, after hearing the boy’s message: “Yes, we have had the same over the wire, but could hardly get it. Hurry back, then. I’ll send two others after you. Phoned for them an hour ago. Look out for gas shells; they may be sending them over soon. Listen for the warning gongs from our trenches and the gurgling sound of the shells themselves--you’ll know it. Or you may see the fumes drifting your way in certain lights; after the explosion, sometimes, you can see them very plainly. You can generally smell the fumes in the open before they come near enough to injure you--then on with your masks! By the way,” the Major lowered his voice, “is that helper of yours on the job?” “Yes, sir; you may be sure he is! As cool and not afraid as they make ’em.” Don was glad of this chance to praise Billy. His regard for the youth was hardly less than a strong love for his pal. The doctor seemed surprised. “I would hardly have thought that,” he admitted,--“a gentle kind of a boy. But that kind often fools you. Even girls themselves--some of our demurest nurses are the bravest under fire. Well, I’m glad you like him. Now, you must make a quick get-away!”
