 is intended to fcarify between the rows of drill- 

 ed corn. To me^ however, it appears of very 

 little ufc, except to lighten the foil ; as 1 can 

 find nothing equal to a plough, for the purpofc 

 of cleaning land, and earthing the crop. The 

 greatefl: part of my drills are at lead two feet 

 afunder, and confequently wide enough to ad- 

 mit of a plough going between the rows. If 

 the rows were nearer tp one another, a fmaller 

 plough might be made to go between tliem. 



I have tried double-moulded or double-breaft- 

 ed ploughs to earth up the rows : but they wiji 

 not at all do in drill-hufbandry, as you cannot 

 humour them to the width of the rows, which 

 are fometimes a little wider or narrower y and 

 if they vary but an inch or two, it deflroys the 

 effe(5l intended, as the mould cannot be regu- 

 larly raifed, and the corn will be in fome places 

 high, in fome low* A common plough will 

 perform this work to perfedion : the expencc
