Famous quotes containing the words list of, list and/or features:

    A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.
    Henry David Thoreau (1817–1862)

    Lovers, forget your love,
    And list to the love of these,
    She a window flower,
    And he a winter breeze.
    Robert Frost (1874–1963)

    The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.
    Marcel Proust (1871–1922)
