THE YEW. 



pendently of the old roots, grows vigorously, and 

 in time becomes a tree, standing in the centre of 

 the hollow trunk, remaining perhaps partially 

 united to the parent, but deriving its support 

 principally from the soil. A tree thus formed, 

 several feet in diameter, stands in the centre of 

 the great Yew at Mamhilad (described above), 

 and will probably continue to flourish for cen- 

 turies after the wooden walls with which it is 

 enclosed have crumbled to dust. A similar phe- 

 nomenon has been observed in the Willow.
