“There’s rust on that barrel,” growled Bill and held out his hand. “I can see it even in this light.”

“But—but I think,” stammered the sentry, “that my officer is mistaken!” He passed over the gun without suspicion.

Immediately afterward, he found himself in the same dilemma Otto had encountered ten minutes earlier. Tied up and gagged with a handkerchief, he was deposited behind a pile of deck chairs.

His captors wasted no further time. They ran down the gangway and piled aboard the skiff moored to the grating. Hans got out the single pair of oars, Osceola unloosed the painter, and Bill, who seated himself beside Charlie in the stern, steered their small craft away from the ship. There were men on the Amtonia’s bridge but they received no hail to return.

Bill looked about. Although there was no moon, the brilliant starlight gave ample light for him to size up his surroundings. He found that they were floating in a large cove or harbor almost landlocked. The body of water was eggshaped; perhaps a mile long by half that distance in width. The shores were rocky, with black patches of sandy beach. Beyond grew a dense forest, except at one end of the bay, where twinkling lights marked a small settlement. The outlet to the ocean was narrow, and guarded by high cliffs. It was a perfect retreat for the Baron and his pirates.

Charlie piped up in his boyish treble. “The Amtonia’s absolutely hidden by those heads from any ship passing up or down the coast. The harbor entrance makes a right-angled turn half way to the sea. I heard Lieutenant Brinkerhoff say that a warship passed the mouth, going west, about eleven-thirty. The lookout on the head signalled in. Brinkerhoff was laughing about it, I guess it made him feel good.”

“Well, his break is ours now,” declared Bill. “And there’s another one for us!”

He pointed to where the Flying Fish lay moored, with her wings spread, a few hundred yards away.

“It’ll be hot as Tophet in her hull tonight! Row on, Hans. We’re going over there to pay a visit. By the way, does anyone know exactly where we are?”

“Yes, sir,” replied the man, “this harbor is on the coast of Maine. Washington County, I think, sir—not very far from Englishman’s Bay.”
