had made many experiments on the subject, and I quite believe he is right."
"Ay, sir; but there is more than that to be learnt from the color of the water."
"Is there, really?"
"Yes, Mr. Clawbonny, you may take a harpooner's word for it; if the Forward were only a whaler, we should have good sport."
"And yet," said the Doctor, "I don't see the smallest whale anywhere."
"All right! Take my word for it, I say, we'll see some before long. It is a lucky chance for a whaler to come across those green stripes in this latitude."
"And why so?" asked the Doctor, always eager to gain information from those who had a practical knowledge of the subject in hand.
"Because it is in those green waters that most of the whales are caught," replied Simpson.
"How is that?"
"Because the whales find most there to eat."
"Is that a positive fact?"
"Oh, I have tested it a hundred times in Baffin's Bay, and I don't see why it should not hold equally good in Melville Sound."
"I daresay you are right, Simpson."
"Stop a bit!" said the harpooner, leaning over the side of the vessel. "Do you see that, Mr. Clawbonny?"
"It looks like the wake of a ship."
"Well, that is the fatty substance the whale leaves behind in its track. Trust me, the animal that left it can't be far off."
There was certainly a peculiar smell in the atmosphere, and the Doctor watched carefully to see if Simpson's predictions would be verified.
He had not to watch long, for the man at the masthead called out:
"A whale! To leeward of us!"
All eyes turned in the given direction; and, sure enough, about a mile from the ship, jets of water thrown up to a considerable height were plainly visible.
"There she is!" exclaimed Simpson. "That's her and no mistake, blowing away!"
