371 COLLECTION OF STATISTICS, 



(cL) Geological map. 



(e.) Soil map. 



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



(r/.) Detailed road map, 



(//.) Map showing the qualities of localit3\ 



There is, however, no need for so manj^ separate maps, as 

 several of them can be combined into one. Ordinarily three 

 maps suffice, namelj' : — 



a. The Geoloyical 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. 



h. Thf' Delaihl Maji. 



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. 



(6.) Contour lines, or height curves. 



(7.) The system of roads and rides, watercourses and other 

 natural lines, with their names. 



(8.) The boundaries of working sections, blocks, compart- 

 ments and sub- compartments, with their names and 

 numbers.
