(). The following Classification of I\fetliO(ls of Regulation of 

 the Cut "Rrtragshestimmung" or "Ertragsregelung", is taken from 

 judeich. 



a. Area Methods ("Flachenmethoden"). 



1. Fixed Yearly Cut (Schlich) : "Schlageintheilung". 



2. .Area .Allotment ; ("Flachenfachwerk"). 



b. Volume Methods ("^Tassenmethoden"). 



1. A'olnme .Allotment ("'Massenfachwerk"). 



2. Methods based on Normal Growing Stock ("Xormalvor- 

 raths methoden"). 



c. Combined Methods ( "Kombinierte Methoden'"). 



1. Area Allotment with Volume Check "Kombiniertcs Fach- 

 werk" 



2. Combination of .Area .Allotment with Methods based on 

 Normal Growing Stock. 



3. -Age Class Methods, i. e., Methods working primarily for 

 Regularity of Age Classes.* ".Xlter.sklassenmethoden" or "Be.siands- 

 wirtschaft". 



As a fourth form he mentions Wagener s Regulation by Cuts 

 of Equal A^alue, which apparently is mentioned more as a curiosity 

 than a thing of value in practice. 



B. The Regulated or Normal Forest. 



Study of a model forest, a perfectly regulated forest, fully 

 stocked and all stands in satisfactory condition, i. e., a "Normal 

 Forest", is of help in understanding not only the methods, but also 

 the real objects of Regulation of the Cut.
