330 DETERMINATION OF THE YIELD. 



the Austrian method. The latter objection could be removed 

 by using suitable yield tables, instead of the final mean 

 annual increment, for the calculation of the increment and 

 normal growing stock, and by measuring the growing stock 

 actually standing in the forest. Nevertheless, the method 

 involves great labour, and the necessary calculations are of an 

 uncertain nature. 



As regards the purely financial principle, the method stands 

 above the methods described under Section III., though it 

 does not do full justice to it. 



SECTION IV. SELECTION OF WOODS FOR CUTTING IN ACCORD- 

 ANCE WITH SYLVICULTURAL EEQUIREMENTS AND THE 

 OBJECTS OF MANAGEMENT. 



The method now to be described has been gradually de- 

 veloped since Heinrich Cotta was called to Saxony in 1811 ; 

 it advanced by steps, until it was finally put into a precise 

 form by Judeich ; hence it is now known as " Judeich's 

 Bestandswirthschaft" The German word " Bestand " can be 

 rendered into English by the word " wood^" meaning part of a 

 forest forming a unit of fairly the same description. The 

 main character of the method lies in the fact, that first of all 

 the requirements of each Wood, are considered, and that the 

 management of the whole forest represents a summing-up of 

 the treatment laid down for each wood. The method ap- 

 proaches the business, therefore, from a point which differs 

 from that of all the previously-described methods, as the latter 

 bring the forest as a whole into play, in order to determine 

 and regulate the yield. 



The first step under Judeich's method is a suitable division 

 of the forest into units, called woods or compartments ; next, 

 a general plan is sketched to indicate the manner in which a 

 normal arrangement of the age classes, both as regards size 

 and grouping, is to be effected ; then the treatment of each 

 wood is determined for a limited number of years ; the cuttings
