        The wings of the weak melody,
      Till some new strain of feeling bear

      And first there comes a gentle sound
      To those in talk or slumber bound,
          And wakes the destined; soft emotion
      Attracts, impels them; those who saw
      Say from the breathing earth behind
      There steams a plume-uplifting wind
