other experiments that follow in this feclion, ought to be 

 varied in the lame manner. 



And as it is alfo poflible that potatoes of* different forts 

 may require a different diftance between them, even where 

 the plants are of the fame weight, it mould be always un- 

 dcrftood that an experiment of this kind is only to be ab- 

 folutely relied on when applied to the particular kind of 

 potatoe that was actually tried ; therefore, if any experi- 

 ments of this nature are recorded, the kind of potatoe that 

 was tried mould be particularly fpecified. After this, it is 

 fcarce neceflary to add, that no intermixture of kinds mould 

 be admitted in any of thefe experiments. 



We ought, in the fecond place> to endeavour in the fame 

 manner to afcertain what is the moft profitable diftance at 

 which plants of all different fizes mould be planted. With 

 this view, a number of plants of equal fizes mould be fe- 

 lecled and arranged into clafles by weight, as in the tabic 

 below, fo that the foregoing experiment can be repeated 

 through all its varieties with each clafs of plants. We 

 (hall make the firft clafs confift of plants of half a pound 

 each, or ten pounds per fcore,as it will be more convenient 

 to weigh the plants by fcores than feparately ; fmaller di- 

 vifions being thus more obvioufly perceptible than if the 

 plants were weighed individually. The weight of the 

 other numbers is marked in the fecond columns.
