that any rotation decided upon at this time will 

 be changed in a revision of the plan in later 

 years. 



While there are certain types such as the old 

 field type of gray birch and red maple which 

 become mature at an early age and should be 

 replaced, it is thought best for the purpose of 

 simplicity to handle the whole forest under a 

 rotation of 100 years. If we exclude 24 acres as 

 blanks, including the brooks, roads, and small 

 areas of brush land, we may consider the produc- 

 tive area of 1,200 acres. Under an ideal arrange- 

 ment a "normal" forest of this area should have 

 an equal distribution of age classes as follows : 





Referring back to the present inventory by age 

 classes, it is evident that the third age class has 

 nearly three times as much area as it should have, 

 while all other classes are deficient. It will be 

 desirable to cut over as soon as practicable the 

 area over 100 years of age in order to get this 

 portion into a more productive condition and 

 thereby increase the area of the first age class. 

 The difficulty is that the oldest stands are the 

 most inaccessible. By planting the open areas 

 and gradually reproducing the least productive 

 areas of the third age class, a more ideal arrange- 

 ment of age classes can be affected.
