IMPORTANCE OF CLOSE UTILIZATION. 
Table 13 gives, for average trees, loss in board feet and percentage 
of loss through, imperfect utilization. Column 2 shows the average 
height of trees of different diameters. Column 3 is the cubic-foot 
content for trees of this size as given in Table 11. Column 4 is the 
board-foot content of the same trees as given in Table 5, showing 
wasteful utilization. Column 5 is the board-foot content of the 
same trees taken from Table 9 ; showing close untiiization. Column 
6 is the difference between wasteful and close utilization in board feet, 
and column 7 gives the percentage of loss in board feet resulting 
from imperfect utilization. The difference runs from 25 per cent 
in the 14-inch trees to 40 per cent in the 36-inch trees.
