it must be affirmed, is substitution only in the sense that wood might 

 have been used, though having in many cases no better priority claim 

 to the field than the so-called substitute. Doubtless much of the use of 

 other products is due to their availability in the most populous regions, 

 whereas more and more lumber has to be brought from the South and 

 the Pacific coast, thus adding heavily to the cost. A just conclusion at 

 the end of the report is that increased studies of the properties of wood 

 and public education on the subject will enable it to hold its own where 

 it is the best material for the purpose at hand.

Die Bedeutimg des Waldcs insbesonderc im Kriege (Importance of 

 Forests in War Time.) By Prof. Dr. Franz von Mammen. "Globus," 

 Dresden, 1916. 



Professor von Mammen discusses the extraordinary part which the 

 forest has played in the world war, as source of wood for the army's 

 tremendous needs, as source of hitherto unheeded food products for 

 man and beast, as source of other raw materials, such as tanbark and 

 naval stores, and its tactical importance in battle.
