From these measurements volume tables were constructed which 
show the merchantable contents for trees of different diameters. 
Measurements of diameter growth were taken on the stump only. | 
The annual rings were counted along an average radius, and the 
diameter growth for each ten years was thus secured. The rate of 
growth of hardwoods, of species of pine whose occurrence was too | 
infrequent to be of importance, and of cypress, of which no trees suit- 
able for such measurements were available, was not obtained.
