LETTER X. 



JJ'AVING ftated the preceding fads 

 relative to the improvement of moors ; 

 I fhall, in the next place, offer fome re- 

 marks on the improvement of another 

 fort of wafte land, but too common in dif- 

 ferent parts of the kingdom : the fort I 

 mean, are the very dry foils, which from 

 fuppofed barrennefs yield nothing but 

 (beep feed ; or applied to that of rabbits : 

 there are many variations in them, but not 

 important enough each to demand a fcpa- 

 rate confideration : the two grand divifions 

 are into foils that are over a flratum of 

 marie, fat chalk, or clay j and others that 

 have not fuch advantages. I fiiall begin 

 with the latter. 



Of thefe the principal tra6l3 which I 

 have viewed, are the wolds in TorkpAre^ 

 fome of the plains in IViliPnre, and Ibme 

 of the heaths in Norfolk, Suffolk and Ca?n- 

 bridgcfiire ; with many other tra^Sls of the 

 fame kind in various parrs of the kingdom.
