Famous quotes containing the words year and/or pack:

    An ordinary man will work every day for a year at shoveling dirt to support his body, or a family of bodies; but he is an extraordinary man who will work a whole day in a year for the support of his soul. Even the priests, men of God, so called, for the most part confess that they work for the support of the body.
    Henry David Thoreau (1817–1862)

    The savage soul of game is up at once—
    The pack full-opening various, the shrill horn
    Resounded from the hills, the neighing steed
    Wild for the chase, and the loud hunter’s shout—
    O’er a weak, harmless, flying creature, all
    Mixed in mad tumult and discordant joy.
    James Thomson (1700–1748)
