3 OS DETET^MINATION AND RErrULATION OF THE YIET.D. 



b. Determination, of the Final Yield. 



The liist step is, to determine the rotation in accord- 

 ance with the objects to be aimed at, as laid do^Yn by 

 the owner of the forest. How this is done lias ah-eady been 

 explained. 



The financial rotation is ascertained by calculating the soil 

 rental, and the forest per cent, for a number of characteristic 

 woods ; in this way it is possible to determine the financial 

 rotation within 10 or 20 years. The rotation actually decided 

 on, as determined by the objects of management, may then 

 be compared with the financial rotation, with a view of 

 bringing out the financial sacrifice involved in a departure 

 from the latter. 



The next ste]:) is, to select, with due consideration of the 

 desired cutting direction and the estal)lishment of suitable 

 cutting series, the woods where final cuttings are called for 

 during the period, for which the working plan is to l)e pre- 

 pared, say, for the next 10 years. Special care is taken not 

 to put down for cutting any wood, the removal of which 

 would expose the adjoining woods to windfall ; or where difli- 

 culties of transport would be encountered. Subject to the 

 modifications caused by these considerations, the following 

 areas would be selected : — 



(1.) All areas which must be cut to meet sylvicultural or 

 protective necessities, such as the establishment of 

 severance cuttings, woods which must be sacrificed in 

 order to work up to a proper grouping of age classes 

 and arrangement of cutting series. 

 (2.) All decidedly ripe or over-ripe w'oods ; the ripeness to 

 be determined by the objects of management. In the 

 case of a financial management, this would comprise 

 all woods, the current forest per cent, of which has 

 sunk below the general per cent. p. 

 (3.) All woods, the ripeness of which is more or less doubt- 

 ful, and which may be situated in the direction of the
