A FRAIL AND BRA UTIFUL SHELL. 



See what a lovely shell, 

 Small and pure as a pearl. 

 Lying close to my foot, 

 Frail, but a work divine, 

 Made so fairly well 

 With delicate spire and whorl, 

 How exquisitely minute, 

 A miracle of design ! 



The tiny cell is forlorn. 

 Void of the little living will 

 That made it stir on the shore, 

 Did he stand at the diamond door 

 Of his house in a rainbow frill ? 

 Did he push when he was uncurled, 

 A golden foot or a fairy horn 

 Thro' his dim water-world ? 



Tennyson.
