Famous quotes containing the words tables, heat and/or combustion:

    O these encounterers, so glib of tongue,
    That give a coasting welcome ere it comes,
    And wide unclasp the tables of their thoughts
    To every ticklish reader! Set them down
    For sluttish spoils of opportunity
    And daughters of the game.
    William Shakespeare (1564–1616)

    And oh, I knew, I knew,
    And said out loud, I couldn’t bide the smother
    And heat so close in; but the thought of all
    The woods and town on fire by me, and all
    The town turned out to fight for me that held me.
    Robert Frost (1874–1963)

    The night has been unruly. Where we lay,
    Our chimneys were blown down, and, as they say,
    Lamentings heard i’ th’ air, strange screams of death,
    And prophesying with accents terrible
    Of dire combustion and confused events,
    New-hatched to the woeful time.
    William Shakespeare (1564–1616)
