"That's us," whispered Mason. "Look important now. This is as good as playing charades. Can you guess the word, Hal?"

For a few minutes those on the deck of the gunboat seemed to be discussing the reply. The little man on the bridge gesticulated violently as he apparently argued with a subordinate officer. Finally he put his marine glasses to his eyes again and for fully a minute Harry felt that he was studying them and Captain Dynamite, who stood facing him, his big form looming up to its full height, while a smile played around the corner of his mouth.

Suddenly the little man danced up and down like a jumping jack, shot his arms in the air and waved them wildly. Then he seized the megaphone and aimed it at the captain's head. This time the boys could understand the words that he poured out, for he spoke in broken English.

"Ah, ah," he shouted, "I know you now, you el Capitaine Dynamite, el filibust, el buccaneer, el pirate. Surrend—surrend in Queen's name."

The little man's words had an electrical effect on the captain. The smile faded away and his mouth became a set, straight line. In a moment he was all action.

"Go ahead full speed, Suarez," he shouted. "All hands to quarters."

In a moment his orders were transmitted from mouth to mouth and as quickly the quiet decks became transformed. Men in a seemingly endless stream rushed up through the forward hatch from below and scattered about the decks with soldier-like regularity, each taking, without the least confusion, a station to which he had apparently been assigned. Every man was armed with sword, pistol, and rifle, and almost before the boys had recovered from the first gasp of astonishment, the bulwarks were lined with rows of fully armed, determined looking men, who stood silently at their posts awaiting further orders.

George Washington Jenks stepped out of his galley, his black, shining face as usual on a broad grin. He looked aft at the boys, pointed to the gunboat and chuckled.

"George Wash Jenks is not such a bad guesser after all," said Harry. "Mix-up has arrived all right."

"Say, but Hal, do you think there is going to be any real fighting?" asked Bert. All of the boys were intensely excited and nervous from their unusual surroundings.
