. THE USE BOOK. 189 



On DO Forest will all the data suggested in the legend page 

 be of equal importance. Supervisors will decide what class of 

 data is to be taken up first. On well-timbered Forests data 

 relating to timber classification and sales would be most im- 

 Ijortant. Distinct lines should represent the boundaries of ^the 

 classifications : but since the stands of timber on each unit 

 of area will be averaged, classification of minor differences in 

 density of stand within an area iTunnecessary._ The tree i species 

 in^ each timber classification : should be noted whenever possible. 

 To avoid confusion, either tEe appropriate symbol or the com- 

 mon name of the species shown in the legend should be used, 

 not the local name. On practically all Forests the improve- 

 ments, special uses, and alienations should be recorded. Be^ 

 ginning with the most important townships and data, the 

 Forest officers should send in the completed township plats as 

 rapidly as their dutieTwi 11 permit 



The township plats may also be used in Forest work to show 

 the location of burned areas, insect-killed timber, timber sales, 

 trjespa^e^ and special uses involving rights of way or tracts 

 of land of considerable size. In fact, the plats may be used for 

 reporting upon any matter which can be shown by map, al- 

 though they may not always be desirable for small explanatory 

 sketches sent in with correspondence. 



(IniziHi/ tun it*. Tlio grazing map legend is not for use on the 

 1 inch to 1 mile Atlas sheets. Data relating to grazing will be 

 drawn on a smaller scale map. which will form one page of the 

 Atlas. It will be colored with crayons, so that alterations may 

 easily be made when changes occur in the areas open to any 

 kind of stock or when areas are closed against grazing.
