introduces, what is usually only cavalierly treated, consideration 

 of silvicultural matters, some 13 pages out of the 60 referring to 

 regeneration, planting, thinnings, soil protection, etc., as influenc- 

 ing yield regulation. 



The chapter on the methods of forest regulation which is left 

 to the end of the book, brings a short historical review of methods 

 — which in Judeich are treated broadly — and then describes the 

 methods in actual practice in the various German states, Austria 

 and France, giving a particular value to the volume. 



Altogether this volume of 281 pages — as against Judeich's 575 

 pages — covers in a comprehensive yet compact manner the whole 

 subject, and for its brief, direct, yet interesting style deserves 

 attention of American foresters. B. E. F.
