Captain Briggs listened with the deepest interest.

When Frank had finished, he said:

“Your tale interests me much, Captain Reade. Perhaps I may be of assistance to you.”

“Indeed!” exclaimed Frank, eagerly.

“I have seen this white or silver whale. It is no myth, but a reality. Not twenty-four since it blowed not fifty yards from our quarters. We tried then to harpoon it, and chased it for some ways. But it was too wary.”

“That information is of the utmost value to me!” cried Frank, joyfully. “For I know that the strange whale is yet in existence. It is hardly likely that there are two of the species in this vicinity.”

“I am glad, then, if I have been of service,” said the captain, warmly.

“Indeed you have.”

“Can I aid you in any other way?”

“I thank you, but I think not. I will at once start the chase for the monster. I hope to make his acquaintance soon.”
