20 ROCK GARDENS 



sort of promontory on the side of a hill, or on 

 sloping ground. 



This type is practically identical with the 

 last described, except that in this case the whole 

 or the greater part of the hill is dealt with, 

 whereas in the former only one face of it was. 

 The knoll is undoubtedly the better of the two, 

 for with it a much greater variety of aspects can 

 be obtained, and also more scope for developing 

 the different natural undulations of the ground. 

 The aspect is, of course, unimportant, for a hill 

 standing by itself will be open to all points of 

 the compass ; and even if it be part of a larger 

 hill, it will be shaded only on one side, which 

 will not so greatly matter. With this type, 

 also, care should be taken that the surround- 

 ings are suitable. 



As this concludes the types of the natural 

 rock gardens, a few points in connection with 

 them may be mentioned before proceeding to 

 the artificial. 



In the first place, large masses of rock have 

 to be dealt with as placed by Nature's all- 

 powerful hand, and we must therefore adapt 

 ourselves to whatever conditions we may find.
