And show our Spring with banner torn.
Was ever such virago morn?
The wind has teeth, the wind has claws.
All the wind's wolves through woods are loose,
The wild wind's falconry aloft.
Shrill underfoot the grassblade shrews,
At gallop, clumped, and down the croft
Bestrid by shadows, beaten, tossed;
It seems a scythe, it seems a rod.
The howl is up at the howl's accost;
The shivers greet and the shivers nod.

Is the land ship? we are rolled, we drive
Tritonly, cleaving hiss and hum;
Whirl with the dead, or mount or dive,
Or down in dregs, or on in scum.
And drums the distant, pipes the near,
And vale and hill are grey in grey,
As when the surge is crumbling sheer,
And sea-mews wing the haze of spray.
Clouds--are they bony witches?--swarms,
Darting swift on the robber's flight,
Hurry an infant sky in arms:
It peeps, it becks; 'tis day, 'tis night.
Black while over the loop of blue
The swathe is closed, like shroud on corse.
Lo, as if swift the Furies flew,
The Fates at heel at a cry to horse!

Interpret me the savage whirr:
