 iituated, fvvell out till they touch each bther^ 

 they become flat on the fide in cohtadV, but 

 continue to fpread on every bcher fide^ as if 

 not incommoded by their contiguity ; which^ 

 indeed, has one good efFeft : for, in endea- 

 vouring to preferve their rotundity, they force 

 each other into a heeling pofture, thereby 

 giving their tops more freedom of exparifion ; 

 and it fecms to be an undoubted fadt^ that the 

 vigour of a given plant will ever keep pace 

 with the {ize and number of its leaves. 



This leads us to a general rule for afcertain- 

 ing the proper diflance of turncp-plants ; 

 which ought to be fuch as will give them room 

 to keep themfelves in a ilate of vigour and full 

 growth ; without leaving any fpace of ground 

 unoccupied by, or thinly filled withj leaves. 



And this leads us round to the firft pofition^ 

 — that the diflance ought tb be in proportion 

 to the ftate of the foil and the time of fowing. 



For, fuppofing a root of fix inches diameter 

 to require a fpace of twelve inches fquarc,
