(thrasher).—this gentleman is famous for his tail, which he uses for a ferule in thrashing his foes. he mounts the folio whale’s back, and as he swims, he works his passage by flogging him; as some schoolmasters get along in the world by a similar process. still less is known of the thrasher than of the killer. both are outlaws, even in the lawless seas.
