merchantable lengths in 16-foot logs in Arkansas, based on Doyle rule.

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.
