TREE VOLUME TABLES. 



Tables 36 to 44, inclusive, are tree volume tables (for trees under 50 years in age), 

 based on tbe taper table (Table 45) and the log volume tables (Tables 30 to 35). Tables 

 36 and 38 give tbe volume in cubic feet of trees of different diameters and heights, 

 with and without bark. Table 37 gives the per cent of volume subtracted for bark 

 from the figures given in Table 36 to get Table 38. 



Tables 39, 40, and 41 show the volume in board feet of trees of different diameters 

 and heights, 39 based on actual cut of logs and trees followed through the mill, 40 

 based on logs and trees scaled by the Scribner log rule, and 41 scaled by the Doyle 

 log rule. It will be seen that the mill -cut table ranges over 10 per cent higher than 

 the Scribner rule table, and in comparison with Doyle rule table ranges 100 to 500 

 per cent higher on trees under 12 inches in diameter breasthigh, and 25 to 100 per 

 cent higher on trees over 12 inches in diameter. The Doyle rule is commonly used 

 in logging operations in southeastern Virginia, and is very much to the advantage 

 of the mill man when cuttins: small trees.
