Rocket 



( 281 ) 



Rohdea 



Rockeries constructed of a series of terraces, 

 supported by stones and flat on the surface, are 

 verv serviceable. Kaised beds of earth, edged 

 with stones, and with others inserted in the surface 

 of the bed, will accommodate rock plants. A 

 rockery built of solid stone, or formed of piles of 

 stone.-, without earth except on the surface, is of 

 no value.

The popular name "Kocket" is applied to
