the ground may have time to rot before the 

 land be plowed. 



With this precaution, and with a perfon to 

 follow the plow with a fpadlet to grub up 

 the bottoms, and to difengage the tops of

 tainty be got rid of. 



Tl'^t feeds of docks are to be dcflroyed in 

 the fame manner as thofe of other weeds ; 

 namely, with the plow, the harrow, and the 

 roller : with this difference, however, that

 any ol\itx Jirong-rooted perennial plant, the in- 

 tervals between the plowings lliould htjhort : 

 for if they once get themfeives ejtablifjjed in 

 the foil, it is, without a favourable feafon, out 

 of the power of tillage to extirpate them. 



Another precaution with rcfpedt to the 

 feeds of docks is ncceflary : they are fome- 

 timcs/^av; upon the land with corn^ and very 

 frequently with clover. 



From CORN and pulse they may be fepa-

 mon prudence, fow any fpecies of thefc un-
