Slow Sand Filters

Famous quotes containing the words slow, sand and/or filters:

    He is as valiant as the lion, churlish as the bear, slow as the elephant.
    William Shakespeare (1564–1616)

    We noticed several other sandy tracts in our voyage; and the course of the Merrimack can be traced from the nearest mountain by its yellow sand-banks, though the river itself is for the most part invisible. Lawsuits, as we hear, have in some cases grown out of these causes. Railroads have been made through certain irritable districts, breaking their sod, and so have set the sand to blowing, till it has converted fertile farms into deserts, and the company has had to pay the damages.
    Henry David Thoreau (1817–1862)

    Raise a million filters and the rain will not be clean, until the longing for it be refined in deep confession. And still we hear, If only this nation had a soul, or, Let us change the way we trade, or, Let us be proud of our region.
    Leonard Cohen (b. 1934)
