A rain-crow was surprised by the beauty of rainbow after raining.

The pretty Rain from those sweet Eaves 1
Her unintending Eyes-
Took her own Heart, including ours,
By innocent Surprise-

The wrestle in her simple Throat 5
To hold the feeling down
That vanquished her-defeated Feat-
Was Fervor's sudden Crown-
(F.1444/J.1426)
