Famous quotes containing the words rock and/or oil:

    “The acorn’s not yet
    Fallen from the tree
    That’s to grow the wood,
    That’s to make the cradle,
    That’s to rock the bairn,
    That’s to grow a man,
    That’s to lay me.”
    —Unknown. The Cauld Lad of Hilton or, The Wandering Spectre (l. 2–8)
