6 Vegetable Statkks. 
^ach; 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 j by which means I found 
the furfaceofthe wholeplant, above ground, 
to be ecjual 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 fideways 
from the ftem : It had befides a very thick 
bufli of lateral roots, from the eight main 
roots, which extended every way in a He- 
mifphere, about nine inches from the ftem 
and main roots. 
In order to get an eftimate of the length 
of all the roots, I took one of the main roots, 
with its laterals, and meafured 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 lefs than 1448 feet. 
And fuppofing the periphery of thefc roots 
at a medium, to be of an inch, then their 
furface will be 2286 fquare inches, or 15. 8 
fquate
