Famous quotes containing the word stroke:

    The one prudence in life is concentration; the one evil is dissipation: and it makes no difference whether our dissipations are coarse or fine; property and its cares, friends and a social habit, or politics, or music, or feasting. Everything is good which takes away one plaything and delusion more, and drives us home to add one stroke of faithful work.
    Ralph Waldo Emerson (1803–1882)

    This house was designed and constructed with the freedom of stroke of a forester’s axe, without other compass and square than Nature uses.
    Henry David Thoreau (1817–1862)

    Fair maid, white and red,
    Comb me smooth, and stroke my head;
    And every hair a sheave shall be,
    And every sheave a golden tree.
    George Peele (1559–1596)
