14S THE GENERAL WORKING SCHEME. 



As regards the manner of making the cuttings, the Special 

 Scheme of Exploitations must be entirely silent. The character of 

 the Primary Felling (that is to say, whether it should be close or 

 open), the more or less rapid succession of the different Regenera- 

 tion Fellings, the special precautions they require, the manner of 

 making the Improvement Cuttings, &c., all these are questions that 

 perforce vary with the locality operated upon and with a host of 

 natural or accidental causes. Any attempt to lay down rigid 

 directions must run the risk of prescribing incomplete or untimely 

 operations. Besides, there is always the liability of falling into 

 grievous error in trying to predict the course of natural phenomena. 

 The prescriptions of the Special Scheme of Exploitations are 

 obligatory, once they are sanctioned by supreme authority, and it 

 stands to reason that the Executive Forest OfiScer must be held 

 responsible for the cuttings made by him. He must therefore be 

 given full discretion in executing them in whatever way he considers 

 best. 



If it is necessary to avoid laying down in the Organisation 

 Project the manner of making the cuttings prescribed, that is no 

 reason for omitting to discuss and record facts that have been 

 observed. But the place for- this is not the Special Scheme of 

 Exploitations. It should be done in the general portion of the Report, 

 as being information that may be of the highest utility, especially 

 to Officers appointed to a new charge. Thus, for instance, it might 

 form a special Chapter coming E^ter the General Statistical Report 

 and immediately following that on choice of Regime, and styled 

 " Application of the Method of Treatment." 



§ 2. Estimation of the Annual Yield. 



Like the order of the exploitations, the annual yield must be 

 determined for only one Period at a time. 



In high forests worked by the Natural Method, the Regeneration 

 Fellings are based on volume, and the Improvement Cuttings on 

 area. Hence two different classes of yield, viz : — 



(I) That of the Regeneration Cuttings, that is, of Principal 

 Produce,
