Hudson

Human madness is oftentimes a cunning and most feline thing. When you think it fled, it may have but become transfigured into some still subtler form. Ahab’s full lunacy subsided not, but deepeningly contracted; like the unabated Hudson, when that noble Northman flows narrowly, but unfathomably through the Highland gorge. But, as in his narrow-flowing monomania, not one jot of Ahab’s broad madness had been left behind; so in that broad madness, not one jot of his great natural intellect had perished.

First, the whales forming the margin of our lake began to crowd a little, and tumble against each other, as if lifted by half spent billows from afar; then the lake itself began faintly to heave and swell; the submarine bridal-chambers and nurseries vanished; in more and more contracting orbits the whales in the more central circles began to swim in thickening clusters. Yes, the long calm was departing. A low advancing hum was soon heard; and then like to the tumultuous masses of block-ice when the great river Hudson breaks up in Spring, the entire host of whales came tumbling upon their inner centre, as if to pile themselves up in one common mountain.
