Famous quotes containing the words brown and/or nature:

    The river’s tent is broken; the last fingers of leaf
    Clutch and sink into the wet bank. The wind
    Crosses the brown land, unheard. The nymphs are departed.
    Sweet Thames, run softly, till I end my song.
    The river bears no empty bottles, sandwich papers,
    Silk handkerchiefs, cardboard boxes, cigarette ends
    Or other testimony of summer nights.
    —T.S. (Thomas Stearns)

    And then, Sir, there is this consideration, that if the abuse be enormous, Nature will rise up, and claiming her original rights, overturn a corrupt political system.
    Samuel Johnson (1709–1784)
