Crown

Then, again, if you fix your eye upon this strange, crested, comb-like incrustation on the top of the mass—this green, barnacled thing, which the Greenlanders call the “crown,” and the Southern fishers the “bonnet” of the Right Whale; fixing your eyes solely on this, you would take the head for the trunk of some huge oak, with a bird’s nest in its crotch. At any rate, when you watch those live crabs that nestle here on this bonnet, such an idea will be almost sure to occur to you; unless, indeed, your fancy has been fixed by the technical term “crown” also bestowed upon it; in which case you will take great interest in thinking how this mighty monster is actually a diademed king of the sea, whose green crown has been put together for him in this marvellous manner. But if this whale be a king, he is a very sulky looking fellow to grace a diadem.
