 quate basis for undertaking the periodic revision. 



The thoroughness of the revision depends on the correctness 

 of the original plan. Only rarely should it be necessary to 

 rewrite the entire plan. Those portions which come under 

 " Orientation," such as physiographic features, social and indus- 

 trial features, and under " Foundation," such as forest descrip- 

 tion, division of area, etc., can either be incorporated directly 

 in the new working plan, or else reference made to the original 

 working plan covering these portions in detail. 



In matters of determination and distribution of the cut as 

 embodied in the general cutting and planting plans, the revision 

 is essentially a recalculation and reallotment. 



The preliminary of every revision should be a working-plan 

 conference to review the plan for the working period just passed 

 and to make suggestions for the ensuing period. The digest of
