“Wouldn’t there be time to try for the sharks first?” said Jack.

“Oh yes, we could give an hour to that,” said the captain; “for perhaps while we are rounding the island our friends of last night will come and fetch their boat. They are welcome to it, I suppose, Sir John. You don’t want to take it back to England as a specimen?”

“No,” said Sir John, smiling, “let them have it; and I hope we shall see no more of them while we are here.”

There was a little excitement among the men as the cutter was lowered down, and a couple of small harpoons, two lances, and a little tub containing a hundred yards of fine strong line carefully coiled in rings were handed down, along with three rifles.

Jack was looking on deeply interested after going with the doctor and Edward to fetch these and the necessary ammunition from the little museum-like place set apart for them and the magazine. He was so much occupied with the preparations and his eagerness to get back that he did not notice a peculiar cough which was uttered behind him twice.

But when it was delivered again with peculiar emphasis close by, and followed by a touch on the arm, he turned sharply round to find Edward looking at him with a most agonised expression of countenance—so bad did the man seem that Jack was startled.

“Why, Ned,” he cried, “what’s the matter? Here, doctor! doctor!”

“Hush! don’t, sir, pray,” whispered the man. “He couldn’t do me no good. Don’t call him, pray.”

“But you look horrible,” cried Jack.

“So would you look horrible, sir, if you was like me.”
