Vapour

To a landsman, no whale, nor any sign of a herring, would have been visible at that moment; nothing but a troubled bit of greenish white water, and thin scattered puffs of vapor hovering over it, and suffusingly blowing off to leeward, like the confused scud from white rolling billows. The air around suddenly vibrated and tingled, as it were, like the air over intensely heated plates of iron.

Beneath this atmospheric waving and curling, and partially beneath a thin layer of water, also, the whales were swimming. Seen in advance of all the other indications, the puffs of vapor they spouted, seemed their forerunning couriers and detached flying outriders.

And how nobly it raises our conceit of the mighty, misty monster, to behold him solemnly sailing through a calm tropical sea; his vast, mild head overhung by a canopy of vapor, engendered by his incommunicable contemplations, and that vapor—as you will sometimes see it—glorified by a rainbow, as if Heaven itself had put its seal upon his thoughts. For, d’ye see, rainbows do not visit the clear air; they only irradiate vapor. And so, through all the thick mists of the dim doubts in my mind, divine intuitions now and then shoot, enkindling my fog with a heavenly ray.
