that has up to this time been worked by the crude boxing method. 
Fig. 2.— Effect of deep chipping on longleaf pine about f>0 years old in Clinch County, Ga. In 
strong winds the leverage is great and the breaking point is mostly at the top of the face. By care- 
less burning a good many of these faces have been deadened. It is known that pine timber may 
be worked for turpentine if done in suitable manner without causing great injury either to its 
value for other purposes or to its rate of growth.
