THE THEORY AND PRACTICE OF WORKING PLANS 137 



column 4 contains only part of a compartment, column 6 must 

 be deferred until the entire compartment has been cut over. 



Where conditions are sufficiently intensive the table may 

 include areas as well as volumes. 



Descriptions and further explanations can always be added 

 if advisable for clearness. 



It is obvious that the cutting plan proper consists only o^ 

 columns i, 2,3, and 4 and the comparison of column 4 wath the 

 allowed annual cut. But for purposes of convenience columns 

 5 and 6 are added, thus making the record complete, though 

 they cannot be filled until after cutting is finished. Based 

 on this record, the cutting plan for 1913 is computed. Having 

 saved 20 M. in 19 12, the administrator would not hesitate to 

 cut 120+20= 140 M. in 1913. Indeed, considerable leeway is cus- 

 tomary in this respect, so as not to tie the administrator's hands.* 



At the end of the decade, if that is the working period, the 

 annual cutting plan sheets are added up and the results com- 

 pared with the general cutting plan; they then serve as most 

 valuable data for the revision of the working plan. 



SECTION THREE 



REGULATION IN SPECIAL CASES 



This section considers the methods of regulating in special 

 cases, such as, I abnormal forests, II transition forests, III 

 wood-lots, and IV turpentine forests. Much of what has gone 

 before will apply directly; it is only necessary here to note the 

 exceptions and departures. 



I. Regulation of Abnormal Forests 



Strictly speaking all forests are abnormal which do not 

 have a normal growing stock, a normal increment, and a normal 

 distribution of the age classes. But in current usage the term 



* In Prussia the Oberforstcr (supervisor) may exceed the allowed cut by 

 10 per cent without first seeking permission from his superiors.
