The foregoing tables are basic and the ones most frequently used. 
Aspen is cut for many special uses and special tables reading in 
linear feet, cubic feet, or board feet may be needed in many in- 
stances. These may be prepared as needed from the taper tables 
which follow. Useful special tables based on site may be prepared 
by combining these tables with the height-diameter table (Table 2) 
in the text.
