 dom. 



Another point previoufly to be confi- 

 dered, is the method of breaking them 

 up : in all the moorlands, I have recom- 

 mended that of paring and burning with- 

 out limitation, and for the beil of all rea- 

 fons, the refult of various and continued 

 experience j but in rerpe6l to the lands in 

 queftiori, the point is by no means fo 

 clear; we have not the fame valuable ex- 

 periments for our guide. In fome of thefe 

 wolds and downs the foil is extremely

 has never been proved : another circum- 

 flance, is the nature of it, relative to its 

 being burnt ; the moors are compofcd t(j

 tables, even to being qiiite matted with 



them ;
