NATIONAL FOREST MANUAL TIMBER SALES. 41 



The data obtained in the examination will be forwarded to the 



Field data sub- supervisor in the form of a map, estimate, and report. 



mitted as map, esti- In all advertised sales recommendations for marking 



must accompany the report where departures from 



the general marking rules are necessary. 



Every report upon timber recommended for advertisement must 



contain at least one map. This must show not only 



the proposed sale area, but also its location with 



reference to the surrounding Forest, topographic features, such as 



ridges, streams, and roads, proposed roads, camps, and mill sites, lands 



under patent or claim, and surveyed lines, if any. 



The map must include enough of the surrounding Forest to show 

 that the timber applied for may be removed without rendering the 

 surrounding timber inaccessible and unsalable. Burns, barren or 

 open land, forest types, and the limits of merchantable timber on 

 slopes will be shown so far as they affect the desirability of allowing 

 the sale. Within the area applied for the forest type will be shown 

 and the topography will be indicated in sufficient detail to demonstrate 

 the ease or difficulty of logging the timber, and to show the natural 

 boundaries of compartments or logging areas. In small sales one 

 map will show all these data, so that maps for blocks are unnecessary 

 the blocks being indicated by dotted lines; this map will be drawn 

 to a scale of not less than 4 inches to the mile, and the forest atlas 

 colors and symbols, as far as practicable, will be used. 



Large tracts require location maps on a small scale, showing only 

 the outline of the proposed cutting, the section lines or other location 

 points, private lands, if any, and dotted lines to represent the accom- 

 panying block maps on a large scale. The latter may then be 

 numerous and large enough to show necessary detail. 



The proposed cutting area, as recommended by the examining 

 officer and covered by his estimate and description, whether or not 

 he agrees with the applicant, must always be clearly defined on 

 the map; so must every part for which there is a separate estimate, 

 description, or important recommendation. 



When reconnaissance maps are available, the preparation of other 

 maps in the field will usually be unnecessary.

Estimate on ^ e . ma P w ^ a ^ wa y s . ^ e estimated. If uncertain 



conditions of sale or differences between the Forest 

 officer and the applicant make it likely that the area recommended 

 may be extended or reduced, estimates for both the larger and the 

 smaller area are required; otherwise the cutting area will be fixed 

 and estimated without reference to other lands. Where applications 

 for adjoining timber are expected, and where the whole body could 

 be most economically examined at one time, the work of estimating 

 may include a large area so that subsequent sales can be made without 

 further estimating. In such cases the estimate of the cutting area 

 covered by the present application must be kept separate and an 

 estimate and report submitted for each additional area which com- 

 prises a natural logging operation. The same methods will be fol- 

 lowed in estimating large bodies of timber which are to be sold. 

 Whenever the Forest on different areas requires different treatment 

 or different stumpage prices, the details of the estimates and report 

 should clearly show such differences.
