Recapitulation. 



The stem of the tree had, at the age of 97 years : 

 A total volume of =55*15 cubic feet. 



Of this was 



= 55-15-51-82 = 3-33 cubic feet 



, 

 Bark 



Leaving 



= 6 per cent, of total volume. 



Timber = 

 Firewood = 



51*7 cubic feet. 

 12 



Total Timber and Firewood = 51*82 cubic feet. 



By graphically representing the volume of wood at the several 

 ages, figure 32 is obtained, which, with the previous diagrams, 

 gives the following data :
