As the sea moves endlessly, restlessly on so do the poems that try so hard to capture the essence of this mighty element. Here is one by Walter de la Mare:

Echoes

The sea laments
The livelong day,
Fringing its waste of sand;
Cries back the wind from the whispering shore-
No words I understand:
Yet echoes in my heart a voice,
As far, as near, as these-
The wind that weeps,
The solemn surge
Of strange and lonely seas.

Very best wishes – Denny Bradbury
