Good Parson Dickson preached, I'm told,
  A sermon—ah, 'twas very old
    And very, very, bald!
  'Twas all about—I know not what
  It was about, nor what 'twas not.
    "A Screw Loose" it was called.

  Whatever, Parson Dick, you say,
  The world will get each blessed day
    Still more and more askew,
  And fall apart at last. Great snakes!
  What skillful tinker ever takes
    His tongue to turn a screw?
