"Sometimes I walk where the deep water dips

Sometimes I walk where the deep water dips
Against the land. Or on where fancy drives
I walk and muse aloud, like one who strives
To tell his half-shaped thought with stumbling lips,
And view the ocean sea, the ocean ships,
With joyless heart: still but myself I find
And restless phantoms of my restless mind:
Only the moaning of my wandering words,
Only the wailing of the wheeling plover,
And this high rock beneath whose base the sea
Has wormed long caverns, like my tears in me:
And hard like this I stand, and beaten and blind,
This desolate rock with lichens rusted over,
Hoar with salt-sleet and chalkings of the birds."
