Some winters, taking leave,
Deal us a last, hard blow,
Salting the ground like Carthage
Before they will go.

But the bright, milling snow
Which throngs the air today—
It is a way of leaving
So as to stay.

The light flakes do not weigh
The willows down, but sift
Through the white catkins, loose
As petal-drift

Or in an up-draft lift
And glitter at a height,
Dazzling as summer’s leaf-stir
Chinked with light.

This storm, if I am right,
Will not be wholly over
Till green fields, here and there,
Turn white with clover,
And through chill air the puffs of milkweed hover.
