VOLUME TABLE FOR WHITE PINE, IN BOARD FEET.2 
Inasmuch as 1 board foot is a board 1 foot long, 1 foot wide, and 
1 inch or one-twelfth of a foot thick, 1 cubic foot must be equal 
to 12 board feet of solid wood. 
The actual measurements of the trees in board feet according to 
the Doyle Rule were thus reduced to cubic feet by dividing by 
12, and the relation between the figures obtained and the total 
volumes of wood and bark given in the table on page 108 were 
computed. The result was as follows: 

| | | 
| Board feet | | Board feet || Board feet

The values in the table on page 108 were multiplied by the per- 
centages just given, and the results were multiplied by 12, in order 
to convert them back to board feet.
