“Each green leaf or each needle is in effect a remarkably well-regulated metal factory. Its operation can be demonstrated experimentally. With the falling of the leaves or needles this supply of metals is scattered by the wind, and the more undergrowth there is, the greater is the dispersion of organic metal salts, which during the winter are pressed down hard by the snow.”

The Legend of Jubal (1869)
Context: Then, as the metal shapes more various grew,
And, hurled upon each other, resonance drew,
Each gave new tones, the revelations dim
Of some external soul that spoke for him:
The hollow vessel's clang, the clash, the boom,
Like light that makes wide spiritual room
And skyey spaces in the spaceless thought,
To Jubal such enlarged passion brought,
That love, hope, rage, and all experience,
Were fused in vaster being, fetching thence
Concords and discords, cadences and cries
That seemed from some world-shrouded soul-to rise,
Some rapture more intense, some mightier rage,
Some living sea that burst the bounds of man's brief age.
