 from much lower elevations. At the present day the beauty of 

 this very interesting and popular class of plants is too well 

 known to need comment. 



Although numerous alpines may be grown in the open border 

 without a particle of rock near them, yet they succeed much 

 better in the rock garden ; whilst for the cultivation of the rarer 

 kinds a well-constructed rockery is absolutely essential, and the 

 effect of such a one tastefully arranged is delightful in garden
