in their growth by other inclemencies of feafon, 

 have much lefs chance of being dry and meally, than 

 others of the fame fort, which have attained their 

 full growth before the coldnefs or inclemency of 

 the weather checked them. The prefent queftion, 

 therefore, does not relate to this, but to the effects 

 that fuch unripe plants have upon thofe produced 

 from them next feafon. If, upon examination, it 

 fhould be found that the due maturation of the 

 plants employed as feed had any effect upon the 

 quality of the future crop, it might help us to 

 account for fome of the foregoing phenomena; be- 

 caufe, in a country of various foils, it might acci- 

 dentally happen, that the crop raifed on a dampifh 

 foil was produced from feeds that had grown on a 

 dry warm foil the preceding year, and had been 

 fufficiently ripened, or the reverfe; but in large dis- 

 tricts, where the foil is in general pretty much of 

 one quality, either warm and dry, or cold and wet, 

 the kind of interchange of feed here alluded to could 

 not fo readily take place. 



But even if it fliould be found that the maturity 

 of the feeds affected the quality of the potatoes, it 

 would not follow invariably that the feeds produced 

 on early dry foils would be better than thofe from 

 later foils, becaufc it might fome times happen, from
