The stormy March is come at last,
With wind, and clouds, and changing skies;
I hear the rushing of the blast,
That through the snowy valleys flies.
(- from William Cullen Bryant, in my great-grandmother's quotation book from 1907)
The other quote was a little more optimistic:
Ah, March! we know thou art
Kind-hearted, spite of ugly looks and threats,
And, out of sight, art nursing April's violets!
(- from Helen Hunt, same book)
