Dr. U. Miiller of Karlsruhe reviews the 

 Forest second edition of Hufnagl's book on For- 



Organization. est Organization. After commenting on 

 the increased Uterary activity among fores- 

 ters, the reviewer cites this notewortliy case of a book on a 

 highly specialized subject receiving a second edition in two years' 

 time. The changes from the first edition are slight ones. 



Hufnagl's working plan methods are those adapted to exten- 

 sive conditions. His yield regulation is by the Stand method. 

 The yield determination may be by any standard method ex- 

 cepting, of course, the period methods (Fachwerks methoden.) 

 Hufnagl's own methods he cites as means of yield determination. 

 To the American reader Hufnagl's methods are available in 

 "The Theory and Practice of Working Plans" (John Wiley 

 and Sons, N. Y., 1913.) Pp. 49, 75, 81, 82 and 83. 



Hufnagl's book is remarkably free from obscuring technicali- 

 ties. Its title of "practical" has been justified by the rapid sale 

 this book has had.

Prussia. 



These differ quite markedly from the 

 prescribed practice for the State forests of Prussia promulgated 

 on March 17, 191 2* since the communal conditions to be served 

 require different treatment. 



Dr. Hemann believes that the regulation of yield should be by 

 the stand method in conjunction with an area-period framework. 

 Supervisors and rangers of communal forests should receive 

 extra pay for the additional duties of preparing the working 

 plan — this in default of a provincial bureau of Forest Organi- 

 zation. 

 The subject is too specialized to warrant protracted discus-
