FORM TABLES. 



The form or taper of shortleaf trees of different diameters and 

 heights is shown in Tables 32 and 33. The points selected are at 

 breastheight (4.5 feet), and successive intervals above the stump of 

 8 feet plus 0.15 foot, or 3.6 inches for a 16-foot length, allowed for 

 trimming the log. Table 34, giving the butt taper at various heights 

 up to breastheight for trees of different diameters, will be found 

 useful in correlating stump measurements with the standard tables 

 based upon breastheight diameters. The same is true of the double 

 width of the bark at breastheight for trees of different diameters 

 and heights shown in Table 35.
