The spleen is seldom felt where Flora reigns;
The low'ring eye, the petulance, the frown,
And sullen sadness, that o'ershade, distort,
And mar the face of beauty, when no cause
For such immeasurable woe appears;
These Flora banishes, and gives the fair
Sweet smiles, and bloom less transient than her own.
