FIGURE 9. 



Diagram of Stand in Middlesex County, Mass. 



Mixed stand of White and Pitch Pine, in which the leading trees are 5 to 9 inches 

 in diameter and 35 to 40 feet in height. The object of cutting here is to reUeve the 

 better species — White Pine — and where the only trees are Pitch Pine, to relieve the 

 better individuals. Pitch Pine is of slower growth and requires more light than 

 White Pine. Thus Pitch Pines 1 and 2 are already falling behind the adjacent 

 White Pines, and at the same time checking White Pines 2 and 3, which are thrifty 

 and i^robably capable of living to take a place in the main crop. Pitch Pine 3, 

 though fairly thrifty, is yet better cut for the sake of White Pines 4 and 5, which 

 will profit by its room. Pitch Pine 6 is already partly suppressed by a thriftier indi- 

 vidual of its own species. The cutting of these trees will improve the composition 

 as well as the growth of the stand.
