weeper on the shore lyrics

In the vale where I once listened out for the light
Where the little birds warble
The ptarmigans babble
And my heart looked about for some rest from its trouble
I cast my eyes downward upon the seaside
And a fair young girl on the shore I espied
Who was sitting and weeping
To see the waves leaping
And over the skyline the sad vigil was keeping
O why are you weeping alone on the shore ?
Now still from your eyes I can see the tears pour
What sorrow and smart
So pierces your heart
That even a midnight it will not depart ?
