celle. These parcelles are the basis of the whole forest organiza- 

 tion and of the course of the management. In each forest dis- 

 trict (canton) those portions are to be segregated which differ 

 in species or in age, or in site, exposure, growth or density 

 of stocking, in such a way that each portion or parcelle can be 

 handled identically throughout. In the records the parcelles 

 are classed as divisions if they are permanent, as subdivisions 

 if only temporary. The parcelles are marked by stones at the 

 intersections of the boundary lines; the boundaries themselves 

 by narrow cleared lines or by signs.

 ing to the following form.*
