"Do you remember what that airship captain said the day we bagged him?" chuckled Billy. "About it being impossible for Americans to get to France?" asked Bart. "You bet I do. I'll never forget that boob. I wonder if he still believes it." "He'd sing a different tune if he were here to-day," observed Tom. "I don't know," laughed Frank. "The German skull is pretty thick. Still you can get something through it once in a while if you keep on hammering." "I guess these fellows haven't any doubts about our being here," observed Billy. "They've had pretty good evidence of it," confirmed Tom, as he watched the enemy captives standing about in dejected groups, waiting to be sent to the rear. One thing that struck the boys forcibly was the disparity of age between the prisoners. There was an unusual proportion of men beyond middle life and of youngsters still in their teens. "Grandpas and kids," blurted out Tom. "The Kaiser's robbing the cradle and the grave," commented Billy. "Germany's getting pretty near to the limit of her man power, I guess." "That's true of France and England, too," observed Frank thoughtfully. "They lost the flower of their troops in the early fighting and they all have to do a great deal of combing to keep their ranks full." "And that's where America has the Indian sign on the Huns," jubilated Bart "We'll have our best against her second best." "We'll trim her good and proper," predicted Frank. "Even at her best, we'd down her in the end. But don't let's kid ourselves. She's full of fight yet, and will take a lot of beating. And there are plenty of huskies in her ranks yet. Look at that big brute over there. He looks as though he could lift an ox." He pointed to a massively built German corporal, who was evidently mad with rage at his capture. He was gesticulating wildly to his fellow prisoners and fairly sputtering in the attempt to relieve his feelings. "Seems to be rather peeved," grinned Tom. "I can't catch on to what he's saying," laughed Bart. "But I'll bet he could give points to a New York truckman or the mate of a Mississippi steamboat. They'd turn green with envy if they could understand him." "He's frothing at the mouth," chuckled Billy. "I'd hate to have him bite me just now. I'd get hydrophobia sure." There was no time for further comment. The officers had had to give the men a short breathing spell, for all were spent with their tremendous exertions. But now after the brief rest, all was bustle and hurry. "The Huns will be back for more," predicted Frank, as he and his friends were set to work changing the sandbags from the side of the trench that had faced the Americans to the other side that looked toward the German third line. "They must be hard to please if they haven't had enough for one morning," growled Tom.
