STEM ANALYSES 



The next step is to find the volume in board feet and 

 cords of all the trees represented in the stand table. This 

 is most easily found by means of a volume table. In 

 most cases, it would be possible for the farmers to secure 

 the desired volume tables from the Forest Service, Wash- 

 ington, D. C, which distributes them free of charge 

 to all applicants. These volume tables — there should be 

 one for each species — give the number of board feet 

 contained in trees of certain diameters four and one half 

 feet from the ground, and of a certain average height.

In the stand table we have recorded the diameter of 

 the trees four and one half feet from the ground (D. B. H.) 

 together with the number per acre and the species. Thus
