each j by numbering of which I had the fur- 

 face of the leaves in fquare inches, which 

 multiplied by the number of the leaves in 

 the correfponding parcels, gave me the area 

 of all the leaves 3 by which means I found 

 the furfaceofthewholeplant, above ground, 



to be equal to 5616 fquare inches, or 39 



fquare feet. 



I dug up another Sun- flower, nearly of 



the fame fize, which had eight main roots, 

 reaching fifteen inches deep and Tideways 

 from the llem : It had befides a very thick 

 bufh of lateral roots, from the eight main 

 roots, which extended every way in a He- 

 mifphere, about nine inches from the ftcm 

 and main roots. 



In order to get an eftimate of the length 

 of all the roots, I took one oi the main roots, 

 with its laterals, and meafurcd and weighed 

 them,and then weighed the other feven roots, 

 with their laterals, by which means I found 

 the fum of the length of all the roots to be 

 no lefsthan 1448 feet. 



And fuppofing the periphery of thefe roots 

 at a medium, to be -f£ of an inch, then their 

 fnrfacc will be 2286 fquare inches, or 1 j. 8
