 (hould be taken down, fo as to make the 

 bottom of the ground have the fame level 

 with the top ; for that is of more conf- 

 cjuence than is generally imagined. If the 

 bottom be clay, and- there is a hollow dug, 

 it holds water ; and when the roots of 

 trees Breach the place, they are rotted. 



A HEIGHT has the fame effect, as it 

 {lops the water, throws it back, and makes 

 the ground all round very wet.
