Rolling boat on roiling seas: heaving and creaking & pitching and listing -- Decks shifting between untenable states, Crew tying in, tethering to what might become the anchor around their collective necks, pulling them all to the depths - 'til the last bubble spills upward from a nostril.
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 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.
Out of a fired ship, which by no way But drowning could be rescued from the flame, Some men leap'd forth, and ever as they came Near the foes' ships, did by their shot decay; So all were lost, which in the ship were found, They in the sea being burnt, They in the burnt ship drown'd.
