LETTER XII. 



'T^HE improvement of thofe wafles, 

 which are fituated on rich foils and 

 overrun with a luxuriant fpontaneous 

 growth, come next to be confidered. 

 There are vaft trails of thefe in many 

 parts of thefe kingdoms, which call for 

 improvement from their pofleflbrs, but at 

 prefent with none. 



The foils of thefe tracts are various; 

 but in general wet, from not enjoying the 

 advantage of being cut by ditches and 

 water-courfes, or ever having had any 

 drains made in them : they confift of clays, 

 loams and gravels ; and are overrun with 

 various forts of trees, fhrubby wood, 

 bu flies, whins, &c, but no ling. The foil 

 is acknowledged by every one, to be equal 

 to the furrounding countries which are 

 well cultivated ; thefe v/aftes will admit of 

 any hufl^andry, from the natural excel- 

 lency of the foil ', they may be converted to 



grrafs
