I Explain

I explain the silvered passing of a ship at night,
The sweep of each sad lost wave,
The dwindling boom of the steel thing's striving,
The little cry of a man to a man,
A shadow falling across the greyer night,
And the sinking of the small star;
Then the waste, the far waste of waters,
And the soft lashing of black waves
For long and in loneliness.

Remember, thou, O ship of love,
Thou leavest a far waste of waters,
And the soft lashing of black waves
For long and in loneliness.
