choose always the same side, say the north side of the major 

 rides, and the east side of the minor rides. 



9. Naming and Numbering of the Divisions of a Forest. 



The methods of naming and numbering the divisions differ 

 much. Judeich recommends the following : 



(a) Working sections receive Eoman numbers = I, II, ... 



(b) Cutting series receive names and slanting capital letters 



= A,B . . . 



(c) Compartments receive Arabic numbers = 1, 2 . . . 



(d) Sub-compartments receive small Eoman letters = l a , l b . . 



(e) Major rides receive upright capital letters surrounded 



by a circle = ^A \ MEM . . . 

 </) Minor rides receive small Arabic figures surrounded by 



(See illustration on page 302.) 



Sometimes a number of compartments are joined into a 

 " block ; " if so, the latter should receive a name. 



The numbering of compartments must be consecutive 

 throughout the working circle ; it leads to confusion to have 

 a separate series for each working section. The numbering 

 should be done so as to indicate the cutting direction. 



In the French State forests the following system of num- 

 bering the divisions is prescribed : 



Working sections are numbered = I, II, III, . . . 

 Periodic blocks ,, ,, = 1, 2, 3 ... 

 Compartments ,, = A, B, C . . . with 



the addition of the number of the periodic block ; 



thus IV (7 2 means Working Section IV, compart- 



ment C in the 2nd periodic block.
