on the scale of 2 inches to 1 mile will be shown. Where neces- 

 sary to show a "small "area in still r^atejr_dtaiL a scale of 4 

 niches to 1 -m|]fl_or_ftyftn.. ft inches to 1_rrp'1p may be employed. 

 Whatever the scale used it will always sustain a simple relation 

 to the standard, as 2 : 1, 4:1, or 8 : 1, as the case may be. It 

 can tESTreadily be reduced to the standard. 



Township plats. Forest officers are supplied with plats of 

 the townships included within their respective Forests. These 

 plats are upon the uniform sen IP of 2 inches to j jOTJle- Each 

 plat represents a township or fractional township, and in a few 

 cases a township plus a fractional township. The plats have 

 been compiled from various sources and j^rinjg together, though 

 not always perfeg^yT^tiT^gata ' a'Piand. for the area represented.

jan^area, they have been usad*. Where township or section lines 

 have been run they are shown by full lines; where not run, by 

 dotted lines. Tracts which have been alienated that is, are 

 in private ownership are indicated by line shading. 



The township plats should be forwarded to rangers as needed 

 for use in three general ways : First, to correct topograjnhy or 

 land lines where .errpra oyist; second, to record data for^the 

 forest Atlas : thir^ to repot^upon any matter which can be 

 shown graphically, even though the record is only of temporary 

 value. 



The plats will be found in error in some cases. Where errors 

 exist they should always be corrected and the corrections for- 

 warded to the Forester. 



In recording data for the Forest Atlas the signs and symbols 

 given on the legend page should be closely followed. If addi- 

 tional conditions are to be shown, any convenient symbol may 

 be used, with an explanation on the margin. Legend pages will 

 be sent to supervisors in sufficient numbers to supply all rangers. 

 The data should be placed upon the plats with as much ac- 

 curacy and neatness as possible. Well-drawn township maps 

 will not be redrawn, but will be mounted directly upon the 

 sheets of the Atlas. It should be the aim of every Forest officer 

 to make his maps good enough to be handled in this manner.
