Carl Sandburg - Docks

Strolling along
By the teeming docks,
I watch the ships put out.
Black ships that heave and lunge
And move like mastodons
Arising from lethargic sleep.

The fathomed harbor
Calls them not nor dares
Them to a strain of action,
But outward, on and outward,
Sounding low-reverberating calls,
Shaggy in the half-lit distance,
They pass the pointed headland,
View the wide, far-lifting wilderness
And leap with cumulative speed
To test the challenge of the sea.

Plunging,
Doggedly onward plunging,
Into salt and mist and foam and sun.

Carl Sandburg
