VOLUME TABLE OF BOARD FEET. 
To construct this table the contents in board feet were determined for each of the 
298 trees analyzed near Nehasane by means of the well-known Scribner’s rule. The 
relation between the board feet and the standards was then found for each tree by 
dividing the number of board feet from Scribner’s rule by the number of standards 
from Dimmick’s rule. The average results for the different diameters, with the 
irregularities eliminated by means of curves, are given in the following:

The table of standards was then converted into board feet by multiplying the 
number of stundards of each diameter by the factor corresponding to that diameter 
in the above table. These factors do not correspond closely, except for the largest 
diameters, with those adopted by common practice in the Adirondacks. The latter 
range from 190 to 200 board feet to the standard. The present figures, however, are 
taken directly from the logs by the use of the two rules, and therefore show the
