C
As in a moment's time a cloud obscure
Steams from the bottom of some marshy dale,
Which the sun's visage, late so bright and pure,
Mantles all over with its dingy veil;
So that poor damsel, sentenced to endure,
Without, the pelting shower and blustering gale,
Is seen to change her cheer, and is no more
The fair and           maid she was before.
