Book XIX: Sea-Drift - The World below the Brine

The world below the brine,
Forests at the bottom of the sea, the branches and leaves,
Sea-lettuce, vast lichens, strange flowers and seeds, the thick
        tangle, openings, and pink turf,
Different colors, pale gray and green, purple, white, and gold, the 
        play of light through the water,
Dumb swimmers there among the rocks, coral, gluten, grass, rushes, 
        and the aliment of the swimmers,
Sluggish existences grazing there suspended, or slowly crawling 
        close to the bottom,
The sperm-whale at the surface blowing air and spray, or disporting 
        with his flukes,
The leaden-eyed shark, the walrus, the turtle, the hairy
        sea-leopard, and the sting-ray,
Passions there, wars, pursuits, tribes, sight in those ocean-depths, 
        breathing that thick-breathing air, as so many do,
The change thence to the sight here, and to the subtle air breathed 
        by beings like us who walk this sphere,
The change onward from ours to that of beings who walk other spheres.
