From thcfc two experiments thus carefully collected it 

 appears, that there is fuch a near coincidence between the 

 produce of the correfponding rows in each experiment, as 

 gives us reafon to believe, that the average obtained from 

 each row is nearly what would refult in general' practice 

 from planting feeds, correfponding to thofe planted in each 

 of thefe rows rcfpe&ively j fo that the corollaries deducible 

 from thence may be admitted as general rules in practice. 



§. III. 



It may, in the flrft place, be inferred, by a care- 

 ful review of thefe two experiments, that the pro- 

 duce is not materially offered by planting for feed, either 

 whole potatoes or cuttings, or large or /mall potatoes 

 merely as fuch -, for that it is only incidentally that either 

 of thefe particulars can affeel the crop. The whole 

 potatoes in the firft row yielded a fmaller produce 

 than the cuttings in the 6th row. Seed from fmall 

 potatoes yielded a fmaller produce than was ob- 

 tained from large ones, in the 5th, 6th, 7th, and 

 8th rows; but it yielded a greater produce than 

 was obtained from the fame large potatoes, in the 

 3d and 4th rows. It feems, in the fecond place, to 

 be a fact confirmed by every ftep in both thefe ex- 

 periments, that the weight of the crop is always in 

 Jome meafure influenced by the weight of the feeds 

 planted. The third and fourth rows, in which the 

 feeds were lightejl, yielded the pooreft crop; and a 

 progrefiion from lighter to more weighty, is obferv- 



able
