Analysis of A Farewell

Flow down, cold rivulet, to the sea,
    Thy tribute wave deliver:
No more by thee my steps shall be,
    For ever and for ever.

Flow, softly flow, by lawn and lea,
    A rivulet then a river:
Nowhere by thee my steps shall be
    For ever and for ever.

But here will sigh thine alder tree
    And here thine aspen shiver;
And here by thee will hum the bee,
    For ever and for ever.

A thousand suns will stream on thee,
    A thousand moons will quiver;
But not by thee my steps shall be,
    For ever and for ever.
