per ftem, (868 bufhels per acre) fo that at the firft period 

 the crop would have attained only about one-feventh part 

 of its whole bulk. 



The reader, however, muft be cautioned not to rely im- 

 plicitly on this experiment as conclufive, on account of one 

 material impropriety in the mode of conducting it. One 

 ftem only can never be fuppofed to afford a fair average of 

 thirty-two thoufand ; more efpecially when it is adverted 

 to, that the feeds planted were in this field cut in the 

 ufual random way; fo that one might have been found by 

 accident much larger than another, and by confequence 

 would greatly affect the accuracy of the trial. — -Had the 

 nine ftems contained within the fmall dotted lines in the 

 diagram been taken up at each period, much greater re- 

 liance could have been had upon it. We mall afterwards 

 find that there is fome reafon to conclude, that the refult 

 of this experiment is not far from the truth : but as many 

 important leflbns to the practical gardener and farmer could 

 be deduced from this experiment, if carefully made, I can- 

 not help recommending it to the attention of the reader, as 

 one of thofe radical experiments that cannot be too care- 

 fully made and adverted to. For were it known with 

 certainty what is the deficiency of weight that in all cafes 

 would accrue from taking up any one kind of potatoe at a 

 particular period of its growth, the practical agriculturift 

 could compute with great accuracy whether the additional 

 price he could receive for the produce at an early period, 

 together with the ufe he could make of his ground after it 

 was cleared, would be fufficient to indemnify him for the 

 lofs in quantity. Thofe who mean to try this experiment 

 would do well to advert to the following particulars; 



i/?. To the equality of the fize of the feeds at planting.
