It is very evident from thefe tables, that 

 rent is no more a guide to product than the 

 •wind ; nor is any particular foil (except the 

 fandy and light being generally the beft) a 

 mark whereby to point out the fcale of pro-

 beft of thofe in the fecond ; this feems as if 

 digging for them was much fuperior to

 fertility of foil, richnefs of manuring, or a 

 general excellent management : A circum-

 preparing in every refpect for wheat in par- 

 ticular, or for any other grain in a very fupe- 

 rior manner. It is extremely evident from 

 the preceding tables that their culture is un-
