The firft ftep would be to afcertain what is the 

 diftance that ought to be allowed between each 

 pLnt, when the feeds are of any given- fize, fo as to 

 obtain the molt weighty crop. 



For Example : 



Let it be required to afcertain at what diftance from one 

 another potatoes weighing half a pound each (that is equal 

 to ten pounds of feed in our experiment) mould be planted, 

 fo as to infure the greateft pollible crop. 



To do this let a plot of ground be made choice of for 

 this experiment, which was of a good quality, and as equal 

 as pofTible in every art. Let this be divided into fmall 

 fquares, each of which mould be fuflicient to contain ex- 

 actly one hundred plants, at each of the diftances it was. 

 intended to afcertain. Thefe fquares mould be divided 

 from each other by a fingle row of potatoes planted at one 

 foot diftance from each other in the rows ; and each of the 

 fquares mould be fo divided as to allow every plant in the 

 outfide rows to ftand at the fame diftance from the divifion 

 rows, as from the other rows in the fquare. That is to 

 fay, each fquare fhould be divided into eleven equal parts, on 

 every fide, fo as to allow ten free rows every way, as in the 

 following Diagram, on which the fmall dots reprefent 

 the divifion rows, and the larger dots the hundred experi- 

 mental plants.
