Nor was it his unwonted magnitude, nor his remarkable hue, nor yet his deformed lower jaw, that so much invested the whale with natural terror, as that unexampled, intelligent malignity which, according to specific accounts, he had over and over again evinced in his assaults. More than all, his treacherous retreats struck more of dismay than perhaps aught else. For, when swimming before his exulting pursuers, with every apparent symptom of alarm, he had several times been known to turn round suddenly, and, bearing down upon them, either stave their boats to splinters, or drive them back in consternation to their ship.

Already several fatalities had attended his chase. But though similar disasters, however little bruited ashore, were by no means unusual in the fishery; yet, in most instances, such seemed the White Whale’s infernal aforethought of ferocity, that every dismembering or death that he caused, was not wholly regarded as having been inflicted by an unintelligent agent.
