THE THEORY AND PRACTICE OF WORKING PLANS 151 



and under the practical restrictions imposed. Past manage- 

 ment and its mistakes and lessons should be reviewed and the 

 proposed method of management given in detail. The best 

 silviculture is not always possible under existing conditions, 

 and the organizer must seek to combine the three divergent 

 factors of object of management, practical restrictions, and 

 silvical requirements into a harmonious scheme of management. 

 This should cover: 



(i) SilvicuUiiral method for each type with brief description 

 thereof. 



(2) Rotation chosen, with reasons for its adoption. The 

 period of reproduction, cutting cycles, etc., should be given 

 and made entirely clear. 



(3) Marking rules to be followed in the execution of the 

 cuttings for natural reproduction. They should be clear and 

 concise, simply put so as to be readily intelligible to the non- 

 technical man charged with their execution, sufficiently elastic 

 to cover all cases. Good marking rules will do much toward 

 insuring the actual execution of the silvicultural method decided 

 upon, especially when backed by sample areas marked by the 

 forest organizer as a concrete illustration. 



(4) Brush disposal rules are a necessary concomitant of the 

 marking rules. Here too actual examples of what is desired 

 should reinforce the written rules. 



4. Regulation 



As the recommended management (3) is the logical out- 

 growth of the data given under Orientation (i) and Foundation 

 (2), so the regulation of the cut itself is but the carrying out of 

 the Recommendation (3). 



The chief phases of regulation are : 



(a) Determination of the Allowable Cut by one or more of 

 the methods already described. Where working groups are 

 formed, each requires a separate determination of the cut. 



(b) Distribution of the Allowable Cut. — Selection of stands to 

 be cut, formation of cutting series, etc., with concise reason for
