190 VOLUME TABLES FOR BOARD FEET 



To test the accuracy of a table of proved value, when applied to 

 a specific stand or region, the volume of as many trees as convenient, 

 preferably about 100 trees, is determined by the same standards as used 

 in the table. The per cent of divergence of the actual volumes, one 

 by one, from those of the table, is computed. These per cents 

 may be tabulated and averaged by diameter and by height; if they 

 reveal a consistent difference in volume, the values of the table can be 

 raised or lowered by the average per cent indicated.
