"I'm only a guest," Dave replied. "Mr. Overton is in command here."
"Thank you, Engineer, but, as we're only cruising I believe our best move will be to stick to Captain Foster's nine-mile order," Hal replied, nodding to Joe.
So the cruise continued. Halstead was soon on deck again, but the young skipper found Darrin so enjoying his trick at the wheel that Skipper Tom merely stood near to take the trick again whenever the young ensign showed signs of being tired of his job.
It was late in the night, and the "Restless" was making her third trip up the river before anything happened. For some time the young Army and Navy officers had felt more or less bored with the monotony of these hours of tiresome waiting. Tom Halstead had stretched himself out on the deck-house for rest, though not to nap, and Hank Butts was at the wheel, while Joe dozed lightly on a seat in the engine-room. All of the enlisted men had crowded below, and were dozing.
"Look sharp, there!" cried Lieutenant Hal, suddenly, as he sprang to Hank's side. "There's a craft moving out from the American shore, about a mile upstream, isn't there!"
"Something moving, for sure," replied Hank, peering through the darkness.
"A motor boat?"
"It must be."
"Trail her. Get in closer."
Skipper Tom Halstead now came forward, though he did not take the wheel from Hank.
