“I say! what’s this?” he exclaimed.

“That!” replied one of the sailors, “why, it’s a piece of rock the beast swallowed by way of ballast.”

“It’s just a bottle, neither more nor less, that the fellow has got in his inside, and couldn’t digest,” said another of the crew.

“Hold your tongues, all of you!” said Tom Austin, the mate of the DUNCAN. “Don’t you see the animal has been such an inveterate tippler that he has not only drunk the wine, but swallowed the bottle?”

“What!” said Lord Glenarvan. “Do you mean to say it is a bottle that the shark has got in his stomach.”

“Ay, it is a bottle, most certainly,” replied the boatswain, “but not just from the cellar.”

“Well, Tom, be careful how you take it out,” said Lord Glenarvan, “for bottles found in the sea often contain precious documents.”

“Do you think this does?” said Major McNabbs, incredulously.

“It possibly may, at any rate.”

“Oh! I’m not saying it doesn’t. There may perhaps be some secret in it,” returned the Major.
