132 THE USE BOOK. 



be clearly shown. Supervisors should bear in mind that all data 

 furnished by any forest officer, including that on map sheets, 

 will not only be of great value in the Washington office, but will 

 tend to simplify the administration of their own reserves. 



2. GRAZING AND ADMINISTRATIVE MAPS. 



When the large scale prints mentioned above are furnished to 

 the forest officers they will be accompanied by reduced prints 

 on a scale of one-half inch to the mile. The map accompanying 

 the annual grazing report (p. 128) should be made on a copy of this 

 small scale map showing in one color the boundaries and num- 

 bers of the grazing districts and, in case they do not coincide, in 

 another color the boundaries and numbers of the ranger districts. 

 In every possible case, however, they should coincide. 



3. MAPS FOR FIELD USE. 



Most of the forest reserves created since January 1, 1904, were 

 examined and mapped by the Forest Service. These maps were 

 made in duplicate on a scale of one- half inch to the mile, one 

 showing the classification of lands and the other the patented and 

 entered claims. These type and title maps, as they are called, 

 will be furnished to every supervisor and as rapidly as possible to 

 every ranger. Blank prints are available now for distribution 

 among the reserve officers and the supervisor will be held re- 

 sponsible that his rangers are furnished with adequate maps of 

 their districts. 



In addition, small diagrams on a scale of an inch and a half to 

 the township are now made as part of the proclamation creating 

 the reserve. These may be had by any forest officer on applica- 

 tion to the Forester. 



CORRESPONDENCE. 



To facilitate filing, every letter or report from a forest officer 

 should contain but one subject. Every application, sale, privilege, 

 trespass, or other transaction identified by an individual name or 

 number, must be treated separately. 



Never write a letter of transmittal in forwarding any document, 

 unless some special statement about it is needed. Indorse the
