FORESTRY QUARTERLY 



ERRATA IN VOLUME XL 



Please Correct! 



A serious error appears in a number of statements, and espe- 

 cially in the tables accompanying the article on Some Aspects of 

 European Forestry, due to the use of an erroneous factor in con- 

 verting cubic meter per hectare into feet board measure per acre. 

 It should also be realized that no single conversion factor can 

 be employed to translate a yield table, since the sawlog per cent, 

 varies with the age. This matter is elucidated under Comment 

 of the present issue. 



By multiplying with the factor .84 the board feet statements 

 can be reduced to a correct cubic foot statement in the tables re- 

 ferred to.
