From “Two Tramps in Mud Time”, by Robert Frost
The sun was warm but the wind was chill.
You know how it is with an April day
When the sun is out and the wind is still,
You’re one month on in the middle of May.
But if you so much as dare to speak,
A cloud comes over the sunlit arch,
A wind comes off a frozen peak,
And you’re two months back in the middle of March.
A bluebird comes tenderly up to alight
And turns to the wind to unruffle a plume,
His song so pitched as not to excite
A single flower as yet to bloom.
It is snowing a flake; and he half knew
Winter was only playing possum.
Except in color he isn’t blue,
But he wouldn’t advise a thing to blossom.
The water for which we may have to look
In summertime with a witching wand,
In every wheelrut’s now a brook,
In every print of a hoof a pond.
Be glad of water, but don’t forget
The lurking frost in the earth beneath
That will steal forth after the sun is set
And show on the water its crystal teeth.
