4. The time of fod-burning depends upon 

 thtfeafon and the intended crop. 



It is always imadvifeable to pare in a v:et 

 fcafon. The covering moid and feeble, and 

 the fod fopt with wet, fall heavy and flat to 

 the ground. The grafs foon rots ; and if the 

 feafon continue moifl, the roots will in a 

 little time regain a footing in the foil. 



On the contrary, fods pared in dry weather 

 fall light off the fpadc, and are kept hollow 

 underneath by the grafs or other covering, 

 which in a dry feafon are rigid, bearing the 

 fods froni the ground, thereby admitting a 

 circulation of air beneath them ; by v/hich 

 means the extra cxpence and trouble oi fet- 

 ting is avoided, and the procefs of cineration 

 rendered much lefs difficult and irkfome. 



The CROP, therefore, ought to be in fomc 

 meafure fubfervient to the season. 



5. The crops moll in ufe for fod-burnt land 



are WHEAT, RAPE, TURNEPS, BIG, OATS. It 



is feldom, however, that a paring feafon can 

 be got early enough in the fpring for either 

 of the latter crops ; the laft more efpecially. 

 Big, however, is frequently fown on burnt 

 land the latter end of May, or the beginning
