words there has been no appreciable clean cutting 

 during the past twenty years and none of any 

 extent for forty years since the charcoal market 

 disappeared. Most of the land was cut over, 

 so far as hardwood is concerned, between 1850 

 and 1890, but about 6% of the area has a growth 

 over 80 years of age. Most of the trees 12" 

 and over in diameter are doubtless on these 

 portions, which are naturally the most inacces- 

 sible steep slopes. 



Practically no lumber has been produced in 

 this forest in less than forty years. Over half 

 of the lumber is between 40 and 60 years; one- 

 quarter between 60 and 80 years, although only 

 one-eighth of the area is in this age class. The 

 age classes above 80 years produce 18% of the 

 lumber, although they cover only 6% of the area. 



GROWTH OF FOREST 



A growth analysis of 1,001 acres of wooded 

 land having a forest 20 years or more old is 

 given in Table No. 4.
