虽然唯一的吐口是鳍式捕捞，属于不可接受的鲸鱼，因为它具有令人难以置信的游泳力量。然而，鳍后卫的喷口与抹香鲸的吐口非常相似，以至于不合适的渔民经常被误认为。因此，德里克（Derick）和他的所有主人现在都在勇敢地追逐这种不可能的野蛮人。处女拥挤在她的四个年轻龙骨之后制作的所有航行，因此它们都消失在远处，仍然大胆，充满希望的追逐。哦！我的朋友，许多是鳍。
(though the only spout in sight was that of a Fin-Back, belonging to the species of uncapturable whales, because of its incredible power of swimming. Nevertheless, the Fin-Back's spout is so similar to the Sperm Whale's, that by unskilful fishermen it is often mistaken for it. And consequently Derick and all his host were now in valiant chase of this unnearable brute. The Virgin crowding all sail, made after her four young keels, and thus they all disappeared far to leeward, still in bold, hopeful chase.Oh! many are the Fin-Backs, and many are the Dericks, my friend.)
