"Did you hear what Voissard was telling me about the megaphones posted outside the city?" asked Roger.
Ignace, Schnitzel and Bob answered in the affirmative.
"I only caught part of it. I was talking to Jack," replied Jimmy. "What was it he said?"
"Well, they call these megaphones 'the ears of Paris.' They are recording reversed machines with microphone attachments. They're set up in clusters of four at different points just outside the city. Through them the sound of an airship's engine and propellers can be heard five miles away. There's a look-out for every bunch of 'em. The minute they begin to hum he sends warning. Then, bing! The searchlights blaze up in the sky and a flock of aeroplanes get busy and attack the Boche raiders."
"Good work!" approved Jimmy. "I wonder if it's the same in London? There seem to be more raids there than any place else. Almost every big raid you read about's on London."
"I suppose the fog gives the brutes more of a show to drop bombs," reflected Schnitzel.
"It's a horrible business," growled Bob. "I'm glad the Allies are beginning to give the dogs some of their own dope. I wish they'd wipe Germany off the map."
"She'll do that for herself if she keeps on trying a little longer. I'd hate to be deutschy Deutschland when our Allies get through with her. She'll sure be out in the cold," predicted Roger.
"Let her freeze. She deserves it," was Jimmy's vengeful opinion.
"So think I," echoed Ignace, who had been plodding tranquilly along with his Brothers in his usual silent fashion.
