Now to determine the felling budget by which the forest is to 

 be brought to normal condition of which we know nothing positive 

 — the normal idea of the regular timber forest is of no avail — it 

 is necessary to assume that with a certain amount and certain size 

 class proportion the ideal condition is attained. This conception 

 may be derived from portions of the stand which appear to the 

 judgment of the regulator as normal. The authors assumed 5,000 

 to 5,700 feet as normal volume and a composition of 20% small, 

 30% middle and 50% stout trees, the aim being to keep as much 

 as possible stout material on which to deposit increment. This is 

 only an assumption, but by the control gardually it will be modi- 

 fied to correspond to the actual increment per cent. The method 

 requires much judgment and calculation. 



An example of the procedure in a concrete case further eluci- 

 dates the method. 



The author's conclusion then, as to the value and application of 

 the selection forest for the improvement of farmer's woodlots is, 

 that while it would be dangerous to be dogmatic, a possibility in 

 that direction exists. The wind firmness secured, especially for 

 such small isolated lots recommends it, as well as the independence 

 of each parcel in its management, hence no need of the associated 

 effort. In this sense the Bavarian instruction also expresses 

 itself.

In antagonism to the tendency to reduce 



Higher rotations and to form forest reserve funds, 



vs. from which to eke out eventual deficiencies 



Lower in the year's budget, as has been done lately 



Rotations. in Wurttemberg, Oberforstrat Frey makes 



interesting arguments and calculations, 



using concrete figures. 



According to Schwappachs money yield tables a management 

 class of pine on site i in 70 year rotation, that is to say a property 

 of 7 hectar, one hectar each of 10, 20, 30 to 70 years of age, would 

 have a stock value of 2748 mark per hectar (around $264 per 

 acre) and furnish an annual return of 621 mark of 88.8 per hectar 

 (say $855 per acre). If the same 7 hectar were stocked with stands 

 corresponding to double the rotation, that is to say one-half acre
