For broad trees: 



D. Summary 



On surveying the results of the foregoing inquiry, the following 

 relations appear to be throughly confirmed. 



(1) The form of any tree bole obeys the formula 



h _,.. b' 



ax—- 



a'x- 



y=ce or y=c'yme 



where y is the radius at the section which is situated at the distance x 

 from the tip, and a, b, c and a', b', d are the constants which vary with 

 the individual tree. 



(2) As a crude approximation, the contents of an entire tree bole 

 may be estimated by the formula 



La 



l^h- 



Vs='Lgme 



where, Vs, Qm and h are the content of an entire tree bole, breast-height 

 basal area and total height, respectively and L, Lj and h^ are the constants 

 which vary only with the species.
