"We've had two great days, boys!" exclaimed Frank, "if we never have any others. The day we saw the submarine potted, and the day we nabbed the Zeppelin." "Glory, hallelujah!" crowed Bart. "And to think we've got it in such good shape. The Allies have been crazy for a long time to find out just what new wrinkles the Germans have got in the way of machinery and other features in their latest Zeppelins. Maybe the engineers won't come running when they learn of this!" "And maybe there won't be joy in Paris and London and Washington!" jubilated Tom. "And perhaps the Huns won't gnash their teeth and tear their hair!" chuckled Billy. "Oh, boy, we sure had luck when they sent us out here this morning." "That German officer is a hard loser," remarked Frank. "See that scowl on his face. A thundercloud has nothing on him. He's sore through and through." The boys would have liked nothing better than to have had a chance to explore the Zeppelin and see the many interesting and novel features embodied in it, but their hopes in this direction were doomed to be disappointed. The lieutenant was inflexible in his resolve to have absolutely nothing on the captured airship disturbed until the government experts arrived to inspect it, and sorely against their wills the boys were forced to content themselves with an exterior view of the wonderful fabric. The German officer, being utterly without means of escape, had not been put under the custody to which his crew had been subjected. He stood stiffly by the side of the American lieutenant, awaiting the disposition that the latter might choose to make of him. The American officer sought to question him, but found his prisoner, although able to speak English, inclined to reply only in monosyllables. The courteous persistence of the American, however, had its effect, and the German became more communicative, but he balked at telling where he had been, or what his raid had accomplished. After answering a number of questions of lesser importance, the German himself became the questioner. "To what enemy have I surrendered?" he queried. "To a regiment of the United States Army," replied the lieutenant. A bewildered look came into the prisoner's eyes. "You mean British Army," he suggested, by way of correction. "I said United States," said the lieutenant, briefly. The puzzled look deepened. "Impossible!" he exclaimed. "There is no United States Army in France." Despite himself, the American officer could hardly suppress a smile. "Just listen to him!" exclaimed Frank, who was within hearing distance. "Didn't I tell you the Germans would believe anything their generals told them?" replied Bart. "My, but this is rich!" chortled Tom. "I wouldn't have believed it if I hadn't heard it," chuckled Billy, in a tone too subdued for the lieutenant to notice.
