The foregoing experiment was condiufled with 

 all imaginable care and precifion, the fads are truly 

 ftatcd, and the writer hopes the calculations are jufl:, 



P. S. In clafs 3, article 4, a premium is offered 

 to the inventor of the beft new-conftruded plough 

 for ploughing up potatoe-crops, by which the work 

 may be done with the lead lofs or damage to the 

 crop. As my method of taking up potatoe-crops 

 is not attended with the lead Tofs or damage, and 

 is, I conceive, as expeditious and as little expenfive 

 as can be defired, I rcqueft leave to lay it before 

 the Society. 



As obferved before, I plant my potatoes in rows 

 with intervals of about three feet, for the conve-» 

 niqnce of horfe-hocing them. When the haulm is 

 decayed, I proceed to take them up in the follow- 

 ing manner: — With a common foot or one-wheel 

 plough, much ufed in this part of Hants, and in 

 Wilts; the ploughman having /r/? taken cut the 

 coulter^ and adjufted the wheel fo as that the point 

 of the fhare may be deep enough to pafs under the 

 bed of potatoes, he begins at one end juft under the 

 middle of a row, and with one furrow turns them 

 out on the furface of the ground. Two or three 

 boys or girls follow the plough, and pick them up 

 as they appear i fo that the ground of one row is 



cleared
