ing to its requirement. Finally, silviculture, re- 

 placement of the crop, is the much more impor- 

 tant obligation, assuring continuity of crops, and 

 this can in many cases be practised without the 

 elaborate organization of the ideal business con- 

 duct. 



Of as much and even more moment than the 

 budget regulation for the orderly conduct of the 

 business is the organization of the property into 

 units of management, forest districting. This will 

 be more or less elaborate according to the intensity 

 of the management. 



In Germany, a manager's district, which may 

 comprise from 5000 to 25,000 acres, is divided into 

 compartments of 50 to 100 acres, and sometimes 

 more in each, which form the units of management, 

 being numbered consecutively, and sometimes 

 named. In the level country it is usual to locate 

 these compartments, not only on the map, but in 

 the field, by dividing the property into rectangular 

 blocks separated from each other" by openings 

 (rides) running north and south, east and west, so 

 that on the map the subdivision looks like an 

 American city street system. 1 In the mountainous 

 country the subdivision is an irregular one, the 

 division lines following the contours of the slopes, 

 valleys, and roads, and usually the division lines 

 are not opened. 



1 The rides are used for roads and serve in the pineries also as 

 fire guards.
