Fair modest flower, of matchless worth!
Thou sweet, enticing, bonnie gem,
Blest is the soil that gave thee birth,
And blest thine honour'd parent stem.
But doubly blest shall be the youth,
To whom thy heaving bosom warms;
Possess'd of beauty, love, and truth,
He'll clasp an angel in his arms.
Though storms of life were blowing snell,
And on his brow sat brooding care,
Thy seraph smile would quick dispel
The darkest gloom of black despair.
Sure heaven hath granted thee to us,
And chose thee from the dwellers there,
And sent thee from celestial bliss,
To show what all the virtues are.
