Schlich, the "Bestands wirtschaft" or "Alters Klassenmethode" of 

 Judeich himself.* 



9. The following Classification of Methods of Regulation of 

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

 Judeich. 



a. Area Methods ("Flachenmethoden"). 



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



2. Area Allotment ; ("Flachenfachwerk"). 



b. Volume Methods ("Massenmethoden"). 



1. Volume Allotment ("Massenfachwerk"). 



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

 raths methoden"). 



c. Combined Methods ("Kombinierte Methoden"). 



T. Area Allotment with Volume Check "Kombiniertes 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. * "Altersklassenmethoden" or "Besiands- 

 wirtschaft". 



As a fourth form he mentions Wagener's Regulation by Cuts 

 of Equal Value, 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. 



* See also the recent Textbooks of Judeich, Martin, Guttenberg, Stoetzer, 

 Weise; also Official Instructions of Bavaria, 1912; Borgman's "Die Ent- 

 wickelung d. Forsteinrichtungswesens Eberswalde Biesenthal" ; and Schil- 

 ling's Article in "Zeitschrift fur Forst und Jagdwesen," 1913, October. 



* It is* singular that Judeich persisted in the above Classification of this 

 most important of all Methods. A glance at his problems and explanations 

 shows that it is an Area Regulation with volume merely as a check. Stoetzer 

 (see p. 213 of his book) recognized this and calls it a "limited Area Allot- 

 ment", "beschranktes Flachenfachwerk. See also Schilling in "Zeitschrift 

 fur Forst und Jagdwesen," 1913, October. But also Wagner's "Grund- 

 lagen, etc "
