These volumes are, of course, not directly comparable with, each 

 other: they have a meaning only when individually compared with 

 normal volumes for the same age. It was necessary, therefore, to 

 curve data collected on normal trees, such as were selected for vol- 

 ume tables in larger numbers on the same area. The most reliable 

 portion of this curve lies between 80 and 180 years. The relation of 

 the actual to the average volume of trees of the same age we may 

 use as an indeN of suppression or dominance of the individuals in 

 question. 



The volume of the decayed part of the bole was figured as the 

 affected part of the cone. But instead of giving the decay simply in
