APPENDIX. 



Tables 12 to 15 show the volumes of average hemlock trees, in board 

 feet, Scribner rule, in the Lake States and the Southern Appalachian 

 region. These are based both on the total height of the tree and on 

 the number of logs. Table 16 gives both the cubic-foot and the board- 

 foot volumes (by actual measurement, not by log scale) of small- 

 sized hemlock in northern New Hampshire. Table 17 gives the mer- 

 chantable cubic volume of hemlock (including bark) in the Lake 

 States. Cubic volumes may be reduced roughly to cords by dividing 

 by 90. The volume without bark can be obtained approximately by 

 deducting 19 per cent from the total volume for Lake States figures 

 and the following per cents for Southern Appalachian measurements :
