94 THE USE BOOK. 



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

 only the outline of the "proposed cuttmgrt&e section lines or 

 other location points, the private lands, if any, and dotted lines 

 to represent the accompanying compartment maps on a larger 

 scale! The" ' JatteT"may theiTbe numerous "and large enough to 

 show necessary detail. 



The proposed cuttin^area, as recommended by the examining 

 officer "arid 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^ior^which there is ji separate 

 ^e^ti^atejdescription^r recommendation,. 



Estimate. Always estimate, thp tlmber_upon a definite cut- 

 ting area recommended and shown on the map. An average for 

 any large area ot wiiich thistract forms a part is insufficient. 

 If uncertain conditions of sale or differences between the Forest, 

 officer and the applicant make it likely that the area recom- 

 mended may be extended or reduced, then estimates for both 

 the larger and the smaller area are required ; otherwise, the 

 cutting area should be fixed and estimated without reference to 

 other lands. Where applications for adjoining timber are ex- 

 pected, and where the whole body could be most economically 

 examined at one time, the work of estimating may with advan- 

 tage include a large area, so that subsequent sales may be made 

 without further examination. 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 

 area which comprises a natural logging operation. The same 

 methods should be followed in estimating large bodies of timber 

 which are to be sold at once, when estimates should be made of 

 each compartment or body of timber. Whenever the forest on 

 different compartments requires different treatment or differ- 

 ent stumpage prices, the details of the estimate and report 

 should show the reasons. 



When there is more than one forest type within a cutting 

 area or compartment, the estimate must be based upon separate 

 ^estimates in each type. When the application does not^include 

 all the merchantable timber on the cutting area, the Forest
