Famous quotes containing the words soils and/or serpentine:

    He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.
    Ralph Waldo Emerson (1803–1882)

    I lay awake awhile, watching the ascent of the sparks through the firs, and sometimes their descent in half-extinguished cinders on my blanket. They were as interesting as fireworks, going up in endless, successive crowds, each after an explosion, in an eager, serpentine course, some to five or six rods above the tree-tops before they went out.
    Henry David Thoreau (1817–1862)
