GARDEN PLANNING 



One great charm of the rock garden is its 

 variety, and that can best be maintained by 

 providing all the conditions of aspect and ex-

 tuffa, limestone, and conglomerate will do. 

 Soft stones which crumble away under weather 

 influence are obviously unsuitable.

 that which is porous. 



Clinkers, vitrified brick fi apments, dressed

 lumps of alabaster, minerals, and sea-shells 

 should never be seen in the alpine garden. 

 Tree stumps also should be avoided, as they
