THE USE BOOK. 93 



If the period recommended is two years or longer, the minimum 

 amount of timber which the purchaser should be required to log 

 each year should be determined. If it will be necessary to 

 build logging camps or other buildings, flumes, or roads, their 

 proposed location and their disposition when logging is com- 

 pleted should be ascertained. The value of these improvements 

 to the Forest Service should be considered, as, for example, 

 the use of buildings for rangers' quarters. If the improvements 

 are not bought by the Forest Service the purchaser will be 

 allowed a definite period after completion of the logging for 

 their removal. If they are not removed within this period they 

 will revert to the Forest Service. 



Form of report. The result of the examination should be for- 

 warded to the supervisor in the form of a map, estimate, and 

 description, and a report giving the information called for on 

 Form 578 a. In all advertised sales recommendations for mark- 

 ing must accompany the report. 



Map. Every report upon timber recommended for advertise- 

 ment must contain at least one man. This must show not only 

 the proposed saje_jvrea, but also its location with reference^ to 

 surrounding forest, topographic features, such as ridges, 

 streams, and roads, jtroposod roads, camps, and mill suites, lands 

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



The map must include enough of the surrouding foresj 

 show that the timber applied for may be removed without 

 derTng the surrounding timber inaccessible and unsalable. 

 Burns, barren or open land, forest types, and the limits of mer- , 

 chantable timber on slopes should be shown so far as they affect 

 the deslramiiiy r of allowing the sale. Within the area applied 

 for the forest types should be shown, and the topography should 

 be indicated in sufficient detail to demonstrate the ease or diffi- 

 culty of logging the timber, and to show the natural boundaries 

 or^ compartments or logging- nres. in small sales one map will 

 "show all these data, so that compartment maps are unnecessary, 

 the* compartments being indicated by dotted lines. This map 

 should be drawn to a scale of not ^less than 4 inches to the 

 mile, and the Forest Atlas colors and symbols should be used.
