BOOK II. (Octavo), CHAPTER II. (Black Fish).--I give the popular fishermen's names for all these fish, for generally they are the best. Where any name happens to be vague or inexpressive, I shall say so, and suggest another. I do so now touching the Black Fish, so called because blackness is the rule among almost all whales. So, call him the Hyena Whale, if you please. His voracity is well known and from the circumstance that the inner angles of his lips are curved upwards, he carries an everlasting Mephistophelean grin on his face. This whale averages some sixteen or eighteen feet in length. He is found in almost all latitudes. He has a peculiar way of showing his dorsal hooked fin in swimming, which looks something like a Roman nose. When not more profitably employed, the sperm whale hunters sometimes capture the Hyena whale, to keep up the supply of cheap oil for domestic employment-as some frugal housekeepers, in the absence of company, and quite alone by themselves, burn unsavory tallow instead of odorous wax. Though their blubber is very thin, some of these whales will yield you upwards of thirty gallons of oil.
