Famous quotes containing the words open, game and/or license:

    And open field, through which the pathway wound,
    And homeward led my steps. Magnificent
    The morning rose, in memorable pomp,
    Glorious as e’er I had beheld—in front,
    The sea lay laughing at a distance; near,
    The solid mountains shone, bright as the clouds,
    Grain-tinctured, drenched in empyrean light;
    William Wordsworth (1770–1850)

    He may travel who can subsist on the wild fruits and game of the most cultivated country.
    Henry David Thoreau (1817–1862)

    Nature is mythical and mystical always, and works with the license and extravagance of genius. She has her luxurious and florid style as well as art.
    Henry David Thoreau (1817–1862)
