But it is not enough to look upon a rolling main,
  Forget, or half-forget, and look again,
  And so for ever.

And it is not enough for me to view a fair campaign,
  Forget, or half-forget, and view again,
  And so for ever.

And it is not enough to gaze upon a nebule-streak,
  Forget, or half-forget, and gaze again,
  And so for ever.

And it is not enough to pore upon a woman's cheek,
  Forget, or half-forget, and pore again,
  And so for ever.

But more I do not; neither hope to do. My life is vain.
  And I must languish till these memories wane,
  And sleep for ever.
