VOLUME TABLE, IN BOARD FEET, FOR WHITE PINE 

 IN MASSACHUSETTS 



Courtesy of Massachusetts State Forester 



NOTE. To estimate the contents of a piece of timberland the forester 

 measures a certain percentage (the smaller the tract the larger the percentage 

 must be) of the trees with a pair of calipers. The trees are always measured 

 outside the bark at a distance of approximately 4$ feet from the ground. The 

 quantity of each kind of timber is then computed by means of a volume table 

 which shows the contents (board feet, cubic feet, market, etc.) of standing 

 trees of different sizes. By multiplying the number of trees of each size and 

 species by the figures obtained from the volume tables, the quantity of timber 

 actually measured is found. If ten per cent of the trees have been meas- 

 sured multiplying this amount by ten will give the volume on the entire tract. 



THE VOLUME TABLE GIVES VALUES ONLY FOR THE SPECIES 

 FOR WHICH IT WAS MADE, e.g., a pine volume table can not be used 

 for white oak.
