52 THE NATIONAL FOREST MANUAL. 



Release. 



When land held under temporary withdrawal is recommended for release 

 by a District Forester, bine prints will be made of the tracing which accom- 

 panies the recommendation, four to be sent with the prepared Secretary letter 

 of transmittal. 



Notice of Release Returned to District Forester. 



When the Secretary of the Interior signs and forwards the order of release 

 to the register and receiver of the local land office the Forester is furnished 

 a carbon of the order. The tracing is returned to the District Forester, in- 

 dorsed with the area, date of release order, and dates of restoration of the 

 land to settlement and entry, together with two blue prints and two return 

 copies of the Secretary letter. The blue priiits and the copies of the letter 

 will each bear indorsements identical with those on the tracing. 



National Monuments. 



The procedure followed in the creation and proclamation of national monu- 

 ments is the same as that followed in boundary changes. 



GRAPHIC INFORMATION. 



FOREST SURVEYS AND MAPS. 



"Instructions for Making Forest Surveys and Maps" is issued in pocket 

 form for the use of field officers. This manual describes the instruments used, 

 explains various methods of surveying, and specifies the forms for keeping field 

 notes ; these forms follow closely the style of the General Land Office. 



The kind of survey, whether by transit, compass, or plane table, and the 

 methods of making it, must be left to the judgment of the officer in charge, 

 who will be guided in making his decision by the purpose for which the sur- 

 vey is made. 



SURVEYING NATIONAL FOREST BOUNDARIES. 



Marking 1 Boundaries. 



The boundary lines of every Forest and the boundaries of private lands 

 within the Forests must be located and marked for the information of the 

 public in order to prevent traspass and to simplify the administration of the 

 Forest. 



Boundary Posters. 



In timber the boundary lines should be marked by blazes, as described in 

 the " Instructions for Making Forest Surveys and Maps." Boundary posters 

 with the proper description should be placed at all corners and at intersections 

 with trails, roads, streams, and ridges. The poster should face outward from 

 the Forest, and should state that it marks the east, north, west, or south 

 boundary, according to the specific part of the boundary line upon which it 

 is placed. In openings, where there is no timber upon which the notices can 

 be tacked, posts should be set. The intersection of boundary lines with impor- 

 tant roads and trails should be prominently indicated by means of painted 

 bigns giving the name of the Forest. 



Retracements and Restoration of Corners. 



Retracements, including the restoration of lost or obliterated corners and 

 marks, should be made in accordance with the circular of instructions issued 

 by the General Land Office. 



Special Surveys. 



Where the boundaries can not bo located accurately by the regular force 

 the matter of their survey by the Interior Department or by engineers of the 

 Forest Service should be taken up with the District Forester. 



Corners and Marks Protected by Law. 



Destroying, defacing, changing, or moving any corner, meander post, monu- 

 ment, or bench mark, or cutting down any blazed line or witness tree on any 

 Government line or survey is prohibited by specific act of Congress, and Forest 

 officers should report violations of this law. 



Record of Boundary Survey. 



When any work in connection with the survey or retracement of boundary 

 lines, or the restoration or referencing of corners, has been performed by a For-
