Paths are an important and necessary factor 

 to be considered. The main paths, such as 

 those that go through the centre of the valley or 

 across the bank and knoll types, may be from 

 7 feet to 12 feet wide, and should be well 

 made. A good surface may be obtained by 

 laying a foundation of about 4 inches of stones, 

 broken fairly small, and covering it with 

 about 2 inches of the finest riddlings from a 

 stone-crusher. They should be rolled well 

 together to make them bind properly. The 

 path should have a decided fall from one 

 end to the other, in order to ensure effi- 

 cient drainage of the banks on either side. 

 This is a point that should be carefully 

 noted. 



It is also very advisable to lay flat stones 

 throughout the rockwork at convenient dis- 

 tances apart, in order to facilitate getting at 

 the plants and to avoid treading on them. 



The main paths will require something in
