MAPS. 275 



r. The S'forJr Map. 



This has for its principal object to give a picture of the 

 manner, in which the area is stocked with wood ; a smaller 

 scale than 4 inches = 1 mile generally suffices for it. The 

 map should contain, apart from the necessarj' details, a 

 representation of the existing species, sylvicultural systems 

 and distribution of the age classes. This can be done in a 

 variety of ways, as for instance in the following : — 



In high forest the principal species are shown by different 

 washes ; the age classes by different shades of the same wash, 

 the youngest being given the lightest, and the oldest the 

 darkest shade ; the regeneration class receives some distin- 

 guishing mark. 



MLced woods may receive a separate wash, or they may be 

 distinguished ))y the addition of small trees or marks of 

 various colours. 



Coppice tcoods may receive a separate wash, if shown on the 

 same sheet. 



Coppice Lcith standards may be distinguished from coppice b}' 

 the addition of miniature trees. 



Selection forest may be indicated by colouring it with the 

 wash of the principal species, and indicating other species by 

 special marks. 



Blanks remain uncoloured. 



The stock map should be renewed, whenever a new working 

 plan is prepared; if this is done, it gives, in the course of 

 time, an excellent representation of the history of the forest. 



By way of illustration, the appended Fig. 50 is added. It 

 illustrates two cutting series, a number of these constituting 

 a working section, or a complete series of age gradations.
