BOOK I. (Folio) CHAPTER IV. (Hump Back).—This whale is often seen on the northern American coast. He has been frequently captured there, and towed into harbor. He has a great pack on him like a peddler; or you might call him the Elephant and Castle whale. At any rate, the popular name for him does not sufficiently distinguish him, since the sperm whale also has a hump though a smaller one. His oil is not very valuable. He has baleen. He is the most gamesome and light-hearted of all the whales, making more gay foam and white water generally than any other of them.
