A wind comes from the north
Blowing little flocks of birds
Like spray across the town,
And a train, roaring forth,
Rushes stampeding down
With cries and flying curds
Of steam, out of the darkening north.

Whither I turn and set
Like a needle steadfastly,
Waiting ever to get
The news that she is free;
But ever fixed, as yet,
To the lode of her agony.

David Herbert Lawrence
