"It's almost too bad that the times are so civilized," murmured Danny Grin. "That little toy princ.i.p.ality would make an ideal pirates'

nest."

"I fancy Monaco has done duty enough in that line in the past centuries," smiled Darrin. "I have been reading up a bit on the history of Monaco. Piracy flourished here as late as the fourteenth century. Even rather late in the eighteenth century every ship pa.s.sing close to this port had to pay toll. And to-day, through its vast gambling establishments, visited by thousands every week, Monaco reaches out and still takes its toll from all the world."

"It won't take any from me," smiled Dalzell.

"That is because you're a disciplined human being, and you've too much character and honesty to gamble," Darrin went on. "But think, with a pitying sigh, of the thousands of poor wretches who journey to Monaco, enter the Casino at Monte Carlo, part with their money and their honor, and then pa.s.s into one of the gardens, there to blow their brains out.

"We shall get a glimpse of the place to-night," Dave continued. "I will admit that I have a good deal of curiosity to see it. So I am glad that we have sh.o.r.e leave effective after dinner. Still, we shan't see anything like the crowd or the picture that we might see if Europe were at peace."

"This is Tuesday night," Dan warned his chum.

"Yes; the night to avoid dangerous questions at mess," Dave smiled.

"Dan, are you still going to try to catch Barnes?"

"Watch me," winked Dalzell.

"Look out, Dan! Such a trap may be set at both ends."

But Dalzell winked once more, then allowed his mouth to expand in that contortion which had won him the nick name of "Danny Grin."

Dave soon forgot Dalzell's threat of trouble for the evening. It had pa.s.sed out of his mind by the time that Ensign Darrin entered the ward-room. Yet soon after the officers had seated themselves the executive officer announced:

"In the interest of fair play to all I deem it best to warn you, gentlemen, that to-night is the night when the first gentleman who asks a question that he cannot himself answer is liable to a penalty of thirty-three dollars to make up the deficit in the mess treasury."

There were nods and grins, and shakings of heads. Not an officer present had any idea that _he_ could be caught and made to pay the penalty.

As the meal progressed Lieutenant Commander Wales finally turned to one of the Filipino waiters and inquired:

"Is there any of the rare roast beef left?"

"Don't you know yourself, Wales?" demanded Totten quickly.

"Why, er--no-o," admitted Mr. Wales, looking much puzzled. "Why should I?"

"Then haven't you asked a question that you can't answer?" demanded Totten mischievously.

"That's hardly a fair catch, is it?" demanded the navigating officer, looking annoyed.

"It is not a fair catch," broke in the executive officer incisively.

"Any gentleman here has a perfect right to ask the waiter questions about the food supply without taking chances of being subjected to a penalty."

"I bow to the decision, sir," replied Lieutenant Totten. "I merely wished to have the question settled."

Some of those present breathed more easily; others yet dreaded to become victims of a penalty proposition that many now regretted having voted for.

As the dessert came on Dan Dalzell turned to Dave.

"Darrin," he said, "can you tell me why it is that a woodchuck never leaves any dirt heaped up around the edge of his hole?"

Dave reflected, looking puzzled for a moment. Then he shook his head as he answered:

"Dalzell, I'm afraid I don't know why."

"Of course _you_ know why, Dalzell," broke in Lieutenant Barnes warningly.

"Perhaps I do know," Dan replied, nodding his head slowly. "However, perhaps some other gentleman would like the chance of answering the question."

Instantly a dozen at least of the officers became interested in answering the question. To each reply or guess, however, Dalzell shook his head.

"If everyone who wants it has had a try at the answer," suggested the executive officer, "then we will call upon Mr. Dalzell to inform us why a woodchuck, in digging his hole, leaves no dirt piled up around the entrance."

There was silence while Dan replied easily:

"It's perfectly simple. Instead of beginning at the surface of the ground and digging downward, the woodchuck begins at the bottom of the hole and digs up toward the light and air."

As Dalzell offered this explanation he faced Lieutenant Barnes, who was eying him scoffingly.

When Dan had finished his explanation there was a puzzled silence for an instant. But Dan's half-leer irritated Lieutenant Barnes. Then came the explosion.

"Shaw!" snorted Barnes. "That's an explanation that doesn't explain anything. It's a fool answer. How does the woodchuck, if he digs up from the bottom of the hole, ever manage to get to the bottom of the hole to make his start there?"

"Oh, well," answered Dan slowly, "that's your question, Mr. Barnes."

"My question?" retorted the lieutenant. "What do you mean?"

"If I understand aright," Dan went on, "you asked how the woodchuck manages to get to the bottom of the hole before he begins to dig."

"That's right," nodded the lieutenant, stiffly.

"That's just the idea," Dan grinned. "I am calling upon you to answer the question that you just asked. You must tell us how the woodchuck manages to get to the bottom of the hole in order to start digging upward."

It required perhaps two seconds for the joke to dawn on the other officers at the long mess table. Then an explosion of laughter sounded, and every eye was turned toward Lieutenant Barnes.

"That isn't fair!" roared the lieutenant, leaping to his feet. "That was a trap! It wasn't a fair catch."

Barnes's face was very red. His voice quivered with indignation.

But Dan Dalzell was smiling coolly as he retorted:

"I'll leave it to the mess if Barnes hasn't asked a question that he can't answer."

"You're caught, Barnes!" roared half a dozen voices, and more laughter followed.

"You asked a question, Barnes, and you can't answer it," came from others.

"That thirty-three dollars will come in handy," called another.

"Pay up like a man, Barnes."
