Famous quotes containing the words blue and/or nature:

    “When the inhabitants of some sequestered island first descry the “big canoe” of the European rolling through the blue waters towards their shores, they rush down to the beach in crowds, and with open arms stand ready to embrace the strangers. Fatal embrace! They fold to their bosoms the vipers whose sting is destined to poison all their joys; and the instinctive feeling of love within their breasts is soon converted into the bitterest hate.”
    —Herman Melville (1819–1891)

    “And thus they give the time, that Nature meant
    For peaceful sleep and meditative snores,
    To ceaseless din and mindless merriment
    And waste of shoes and floors.”
    —Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
