Analysis of A Poet of One Mood

A poet of one mood in all my lays,
Ranging all life to sing one only love,
Like a west wind across the world I move,
Sweeping my harp of floods mine own wild ways.
The countries change, but not the west-wind days
Which are my songs. My soft skies shine above,
And on all seas the colours of a dove,
And on all fields a flash of silver greys.
I made the whole world answer to my art
And sweet monotonous meanings. In your ears
I change not ever, bearing, for my part,
One thought that is the treasure of my years-
A small cloud full of rain upon my heart
And in mine arms, clasped, like a child in tears.
