Although the boys did their best to catch a glimpse from the window of the approaching motor they found it impossible. However, the noise grew more distinct and presently the droning of the motor sounded nearly overhead. As Harry had said, the reports of the exhaust had a sound unlike those from the monoplane. Evidently a third machine was approaching the place where the boys were held prisoners.
"Let's break out!" protested Jimmie. "This is fierce!"
"Wait a minute!" cautioned Ned. "We'll know soon enough!"
"Anyhow, he's got a hot box!" declared Jimmie. "I can smell smoke and he has landed close by. He's been running pretty fast!"
"You've got a great nose on you, Jimmie!" declared Jack, laughing. "If everything you smell was true, what would we do?"
"I smelled your hot box out on Long Island!" Jimmie returned tartly. "Besides," he added, "my nose is as good as the rest of 'em!"
"Nothing the matter with your nose," maintained Jack, "only it's stubbed and freckled and wrinkles when you lose your temper!"
"Yes," agreed Jimmie with a laugh, "and it's got a perfectly good smeller inside! That's more than some folks can say!"
"Wonder what our friend The Rat is doing just about now?" put in Harry. "We haven't heard from him for quite a few minutes."
"Call to him and ask him for a drink of water!"
