Analysis of By the Pool of the Third Rosses

I heard the sighing of the reed
In the grey pool in the green land,
The sea-wind in the long reeds sighing
Between the green hill and the sand.

I heard the sighing of the reeds
Day after day, night after night;
I heard the whirring wild ducks flying,
I saw the sea-gull's wheeling flight.

I heard the sighing of the reeds
Night after night, day after day,
And I forgot old age, and dying,
And youth that loves, and love's decay.

I heard the sighing of the reeds
At noontide and at evening,
And some old dream I had forgotten
I seemed to be remembering.

I hear the sighing of the reeds:
Is it in vain, is it in vain
That some old peace I had forgotten
Is crying to come back again?
