pofe ; the 28 (lone belonging to it, divided thus l 

 the four flone weights to four of the bulls, and two 

 of the three ftone weights to each of the additional 

 bulls. It was thought better to be rather minute 

 here, than trouble the perfon employed in ufing the 

 fward- cutter with any calculations. 



That the inftrument may come as cheap as pof- 

 fible to the publick, the inventor is of opinion, that 

 the expence of the two wheels and the iron axle 

 (which is confiderable) may be faved, by joining 

 ftrongly to the frame at S. No. 3, a piece of wood 

 with a little curve at the extremity of it, refembling 

 the foot of a fledge, formerly much ufed in Scot- 

 land, to carry in the corn from the field ; the par^ 

 of it refling on the ground being kept 1 8 inches 

 (the half diameter of the wheels) from the frame, 

 by a ftrong fupport of wood. 



As the two outer bulls next the frame arc apt to 

 get under it, fo as to prevent the cutting wheels 

 from being taken out of the ground, a thin flip of 

 iron fixed to the infide of the frame, nearly oppofite 

 to the back end of the bulls> of convenient length, 

 will be found neceflary*
