“Yes,” replied another hoarse whisper, “that kid you suspected evidently didn’t hear anything.”

“Confound it, it’s dark as a pit,” came from the first speaker.

“It might be lighter,” replied the other, “but the blacker it is the better for us.”

“Hark at those fellows snoring,” was the next thing Frank heard. The remark was accompanied by a smothered laugh.

“Yes, they are sound asleep as run-down tops,” was the reply.

Frank inwardly blessed the stalwart lungs of Schultz and Le Blanc. All unconsciously the sleepers were helping on their plans.

“Do you think that’s the boys snoring?” asked one of the two men who were cautiously creeping nearer to the aerodrome.

“I hope so,” was the response, “I’d like to see them go skywards with their infernal air-ship.”

“Scudder will have reason to thank us for a good night’s work,” was the next remark of the prowlers.

There was silence for a few seconds and then a jangling sound. One of the men who had the destruction of the Golden Eagle II at heart had collided with Frank’s wire fence.
