Figure 4. White Pine in mixture with White Oak. Domi- 

 nant ti'ees 4 to 7 inches in diameter, 30 feet in height, and 25 

 to 30 years old. The treatment required is a light improve- 

 ment cutting of a stand too thick for its best development. Such 

 are White Oaks i and 3, Black Oak i, and White Pine 6, In 

 all these cases the trees cut are not sufficiently behind the others 

 in height and development to be unmistakably in need of re- 

 moval, but they are all either defective or so placed that the 

 crowns of adjacent trees will be able to utilize the room. The 

 lower diagram shows the stand before, and the upper diagram 

 the same stand after the cutting recommended.
