APPENDIX. 
VOLUME TABLES. 
Volume tables are usually based on diameter at breastheight and 
either the total length of the trees or contents of the tree in number 
of logs of standard length. The contents are most conveniently ex- 
pressed in cubic feet and board feet of saw timber. It will be noted 
especially that the contents of the trees scaled by the Doyle rule is 
very much less than by the Scribner rule. The latter represents 
much more correctly the actual contents of saw timber in pine 
stands up to the size of about 24 inches breastheight. 
Both volume and taper tables for the Piedmont region are based 
upon measurements of well-stocked, even-aged second-growth or 
“ old-field” stands in North Carolina taken in 1909, 1910, and 1911. 
The tables will be found applicable to practically all second-growth 
shortleaf pine throughout the Piedmont region and lower extension 
of the Appalachian Plateau. Volume and taper tables for shortleaf 
pine in Arkansas are based upon the measurements of over 3,000 
trees and show the form and average contents of trees of specified 
diameters in board feet scaled by both the Scribner and the Doyle 
rules. These tables, although based mostly on measurements taken 
on the Arkansas National Forest, have been supplemented and found 
by actual checking to apply in other parts of Arkansas and generally 
over the southern Mississippi Valley.

diameters and heights growing in well-stocked stands in the Piedmont region, 
North Carolina.

height, 1 foot; diameter inside bark of top, 6 to 8 inches.]
