FiGURU 3. Mixed White Pine and Oak. Diameters, 5 to 8 

 inches; heights, 30 to 35 feet; age, 30 to 40 years. This stand 

 furnishes a good example of the need for cutting both in the 

 dominant and the subordinate class of trees. Of dead, sup- 

 pressed, or partially suppressed trees, the best of which are 

 already succumbing to the main crop, White Pines i, 2, 3, 5, 

 and 8 and White Oaks i and 2 are cut to relieve the leading 

 individuals beside them and to utilize the v^ood before it decays. 

 Of the dominant trees. Red Maple i, a comparatively inferior 

 species, is cut because it is beginning to overtop White Pines 

 6 and 7, both thrifty trees, and together more valuable than the 

 Maple. The decision in such cases must depend on the relative 

 health and value of the upper and lower trees.
