Famous quotes containing the words blue and/or nature:

    “The extra worry began it—on the
    Blue blue mountain—she never set foot
    And then and there. Meanwhile the host
    Mourned her quiet tenure. They all stayed chatting.
    No one did much about eating.”
    —John Ashbery (b. 1927)

    “There have been heroes for whom this world seemed expressly prepared, as if creation had at last succeeded; whose daily life was the stuff of which our dreams are made, and whose presence enhanced the beauty and ampleness of Nature herself.”
    —Henry David Thoreau (1817–1862)
