Her little face is like a walnut shell 
With wrinkling lines; her soft, white hair adorns 
Her withered brows in quaint, straight curls, like horns; 
And all about her clings an old, sweet smell. 
Prim is her gown and quakerlike her shawl. 
Well might her bonnets have been born on her. 
Can you conceive a Fairy Godmother 
The subject of a strong religious call? 
In snow or shine, from bed to bed she runs, 
All twinkling smiles and texts and pious tales, 
Her mittened hands, that ever give or pray, 
Bearing a sheaf of tracts, a bag of buns: 
A wee old maid that sweeps the Bridegroom's way, 
Strong in a cheerful trust that never fails.
William Ernest Henley
