 in much the same way as in the more arti- 

 ficial type. For a natural hollow merely 

 means that Nature has already done a certain 

 amount of the work, and man will have to take 

 it up where she left off. 



Now to deal with the iank and kno// 

 types. These, as may be expected, do not 

 require the same amount of work in the 

 earlier stages as those types already described, 

 for, instead of the general formation having to 

 be made, the outline is already there and only 

 requires judicious development. If they are 

 not sufficiently high, this can be rectified by 

 sinking the ground at the base and raising that 

 above with the soil dug out, having previously
