Dr. Adolf Ritter von Guttenberg, Wachstum und Ertrag der Fichte im Hoch- 

 gebirge. Zeitschrift fur Forst- und Jagdwesen, September, 1915, pp. 577-80. 

 Centralblatt fiir das gesammte Forstwesen, March-April, 1915, pp. 130-4. 



Dr. Hemman points out that after the 

 Treatment war all resources will have to be strained 



atid to the utmost, and the forests will have 



Yield more than ever to do their best. Fortu- 



nately, experimentation has gone on long 

 enough to permit a judgment how far felling budgets can be 

 increased, and particularly what kind of treatment may lead to 

 best result. Hitherto, the regulator and the manager, the organizer 

 and the silviculturist have not worked in harmony. 



The author has brought together in tabular form what yield 

 tables show under different treatment, which, therefore, should be 

 the aim of the manager.
