FIGURE 7. 

 Diagram of Stand in Middlesex County, Mass. 



Pure stand'of White Pine. Diameter, 5 to 10 inches; height, 45 to 55 feet. The stand 

 is in need of simple improvement cutting. The trees to be removed on this principle 

 are numbers 2, 4, 5, 7, and 9, all of which are either suppressed or partially sup- 

 pressed, but still restricting the crowns of the better trees beside them. The trees 

 left are vigorous enough and thick enough to restore the cover in a few vears.
