44 ROCK GARDENS 



marked out. Thus a cutting will be obtained 

 (A A) about 40 feet wide, and probably from 

 12 to 18 inches deep, with all soil of any 

 value in heaps (B^ B2) on either side. But the 

 banks must be quite 6 feet high, and at least 

 another 3 feet will have to be sunk in order to 

 achieve this. In the centre of the excavation 

 dig a trench (C) about 3 feet deep and 9 feet 

 wide, the bottom of which will be the path, 

 and throw the soil back on either side over 

 the ground (D) between the heaps (Bg Bg) and 

 lines of section. Now cut out the portion 

 E E, and throw the soil over what has just been 

 removed from C. This will probably raise the 

 bank to from 4 to 5 feet above the bottom of 

 the path, with its sides sloping towards it. At 

 this stage it is well to work out the general 

 formation of the banks in the plot being dealt 

 with ; by this I mean that where it is ultimately 

 intended to have a long and gentle slope, keep 

 the subsoil further back and roughly make the 

 desired gradient, or if a bold and almost per- 

 pendicular bank is required, work accordingly. 

 For further particulars with regard to the 

 formation see page 47.
