48 THE NATIONAL 1 oltEST MANUAL. 





Land-Classification Map. 



The 1;i!id classification should be compiled on lh<> scale th;ii best suils t 

 requirements of the case ;it hand. When a scale of 1 inch to the mile is used 

 the map should be on atlas correction sheets < Form '.H'.h. or it" only ;i small 

 area is involve:! on ineh-lo-the mile township plats. In some cases where it is 

 desirable to show the relation of the change invohed to tin- entire Forest 

 it may be necessary to use a map on the scale of one-halt' inch to the mill-. 

 The map should show land surveys and topography in imlia ink. For unsur- 

 veyed lands the examiner should prepare y sketch map showing drainage and 

 as much additional tojographi<- data as may he practicable. 



The land classification shown on the map should be in conformity with 

 standard Forest Service scheme. 





Title Map. 



The title map will consist either of a duplicate of the base map or of town- 

 ship plats which cover the area, and will show the different classes of aliena- 

 tion by distinctive colors. The map should be provided with an appropriate 

 legend These data should be obtained before a field examination is nnd 

 taken; they may be secured from the supervisor's office, from the district 

 or from the local land office. 



The Boundary. 



On both the land classification and the title maps the existing forest bounda 

 will be shown by a heavy blue-pencil line, and the recommended boundary of 

 either additions or eliminations by a heavy red-pencil line. Whenever prac- 

 ticable the boundary will run on section or quarter-section lines, but whore 

 valuable timber is involved and the land is heavily alienated, it may run on 

 40-acre subdivisions. In a region covered by the General Land Otlice surveys 

 a stream may be used for the exterior boundary only when it is shown as 

 meandered on the official land-office plats. In unsurveyed regions any stream 

 may be used as an exterior boundary which has a reasonably fixed channel 

 and flows continuously throughout the year. The alienations and the forest 

 cover outside the recommended boundary should be shown for a distance suffi- 

 cient to convince the reviewing officer that the boundary has been properly 

 located. When the question^ is one of elimination these same facts should be 

 shown inside the existing boundary. Both maps should be dated and should 

 bear the name and title of the examiner. 



Report. 



The examiner's report should supplement the information given on the map 

 with such detailed description of the natural features of the area in question 

 and of the economic conditions governing its use as are necessary to confirm 

 his recommendations. 



The following outline of topics is suggested as having a bearing on boundary 

 changes. Each should be discussed in so far as it has relation to the particular 

 case under consideration.
