288 COLLECTION OF STATISTICS. 



impresses itself more readily on the mind of the forester than 

 a lengthy description. As it is not possible to represent every- 

 thing on one map, it is usual to prepare different sets, such as 

 the 



(a) Topographical map. 



(b) Detailed map on a large scale. 



(c) Map showing the nature and age of the growing woods, 



called the stock map. 



(d) Geological map. 



(e) Soil map. 



(/) Map showing the working sections and cutting series. 

 (g) Detailed road map. 



There is, however, no need for so many separate maps, as 

 several of them can he combined into one. 

 Ordinarily three maps suffice, namely : 



a. The Geological Map. 



This map should show the geological formation of the upper 

 layers, on which the nature of the soil depends. In it can 

 also be shown the general topography of the area ; the various 

 qualities of locality can be entered by lines of a distinguishing 

 colour into which the quality figure is written. 



I. The Detailed Map. 



The scale of this map depends on circumstances. In India 

 the ordinary scale is 4 inches = 1 mile. In a few cases maps 

 on a scale of 8 inches = 1 mile, and in others of 2 inches = 1 

 mile have been prepared. 



The map should show, amongst other items : 



(1) Name of forest and year of survey. 



(2) Boundaries, all boundary marks being indicated on the 



map and numbered ; boundaries between free property 

 and parts subject to servitudes. 



(3) Names of adjoining properties and their owners. 



(4) Area, total, as well as of the main divisions. 



(5) Areas not used for the production of wood.
