weight of the produce of the refpeclive rows was found to 

 be as under, in avoirdupoife weight. 



The difference between the produce of the third and 

 the fourth rows appeared to me aftonifhing : and as the 

 plants in the fourth row confuted of much larger pieces^ 

 and as thofe in the third row were fmaller than any of the 

 others, this experiment feemed to indicate, that the weight 

 of the produce depended in a great meafure on the weight 

 of the feed planted. 



It likewife feemed, from this experiment, that whole 

 potatoes might in fome cafes be more profitable for feed, 

 and in others lefs fo, than cuttings ; for the firft row ex- 

 ceeded the fecond and third, though it fell greatly fhort of 

 the fourth. The cuttings in the fourth row were much 

 larger, and thofe in the third much fmaller than the whole 

 potatoes in the firft. 



It deferves to be remarked, that the vigour of the ftems 

 ©f each of thefe rows was nearly in proportion to the 

 weight of produce above ftated. 



It is alfo of importance to remark, that although the foil, 

 at the time of planting, was in every refpeft equal through 

 the whole of the experiment ground ; yet, at the time of 

 taking up the plants, that part on which the fourth row 

 grew, was in much better order, and feemed to be much 

 richer, than that where the others had grown , efpecially 

 the third,
