Prerequisites to this method of Management are : perfect utili- 

 zation, excellent market and easy accessibility to all parts of the 

 forest by a complete network of roads. All these exist in Eastern 

 France, where even the stumps sometimes bring a price of 60 

 cents per thousand feet, board measure, in the ground ! 



Aside from reasons of political economy, the conversion from 

 coppice into high forests has been a financial success as the fol- 

 lowing example (the National Forest of Amance, near Nancy) 

 shows : 



1814-1826 net income $1.80 per acre per annum 



1827-1857 net income $2.36 per acre per annum 



1 858- 1 866 net income $5.40 per acre per annum 



1 867- 1 876 net income $5.19 per acre per annum 



1877-1886 net income $3.91 per acre per annum 



1 887- 1 896 net income $5.96 per acre per annum 



1897-1906 net income $3.91 per acre per annum 



Average $4.80 Per Acre Per Annum. 



The fluctuations are, of course, inevitable during the period 

 of transition, especially since 1867, when the transforming into 

 high forest began in earnest. 



The final result will be practically even-aged stands of oak, 

 ash, beech, etc., oak predominating. In this same Forest of 

 Amance there have been inaugurated experiments aiming to 

 compare the desirability of this even-aged high forest with an 

 all-aged selection forest. It is too early to judge results, but 

 it would seem as if the selection type of forest with its constant
