As we have seen, God came upon him in the whale, and swallowed him down to living gulfs of doom, and with swift slantings tore him along 'into the midst of the seas,' where the eddying depths sucked him ten thousand fathoms down, and 'the weeds were wrapped about his head,' and all the watery world of woe bowled over him.
Shafts in South Africa, the United States and elsewhere, are already approximating depths of 5000 ft., a few being even deeper.
The bathymetric range of sessile as well as pedunculate forms down to such depths as twelve or eighteen thousand feet - Verruca quadrangularis, Hoek, 1900 fathoms; Sealpellum regium, Wyville Thomson, 2850 FIG.
From the floor of this vast and profound depression numerous isolated volcanic cones rise with abrupt slopes, and even between the islands of the Hawaiian group there are depths of more than 2000 fathoms. The Society Islands and Tahiti crown a rise coming within 150o fathoms of the surface, two similar rises form the foundation of the Paumotu group where Agassiz found soundings of.
When the river is high the water rolls over the main falls in one great unbroken expanse; at low water (when alone it is possible to look into the grey depths of the great chasm) the falls are broken by crevices in the rock into numerous cascades.
Supposing a number of some species of arthropod or fish to be swept into a cavern or to be carried from less to greater depths in the sea, those individuals with perfect eyes would follow the glimmer of light and eventually escape to the outer air or the shallower depths, leaving behind those with imperfect eyes to breed in the dark place.
The west wind drift sends a stream northwards along the west coast of Australia, the West Australia current, the homologue of the Benguela current in the South Atlantic. The principal feature in the circulation in the depths of the Indian Ocean is a slow movement of Antarctic water northwards along the bottom to take the place of that removed from the surface by evaporation, and by currents in the lower latitudes.
The marginal rises and continental shelves prevent this cold bottom water from penetrating into the depths of the enclosed and fringing seas.
The water from the greatest depths of the Black Sea, I160 fathoms, contains 6 cc. of sulphuretted hydrogen per litre.
Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop; such as the black birch, of which we have some handsome specimens two feet in diameter; its cousin, the yellow birch, with its loose golden vest, perfumed like the first; the beech, which has so neat a bole and beautifully lichen-painted, perfect in all its details, of which, excepting scattered specimens, I know but one small grove of sizable trees left in the township, supposed by some to have been planted by the pigeons that were once baited with beechnuts near by; it is worth the while to see the silver grain sparkle when you split this wood; the bass; the hornbeam; the Celtis occidentalis, or false elm, of which we have but one well-grown; some taller mast of a pine, a shingle tree, or a more perfect hemlock than usual, standing like a pagoda in the midst of the woods; and many others I could mention.
