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.
