178 THE USE BOOK. 



When possible, a map of the proposed route, showing the pri- 

 vate telephone lines, towns, settlers' houses, rangers' head- 

 quarters, lookout points, rivers, creeks, canyons, mountains, 

 ridges, roads and trails, and railroads, with their relative ele- 

 vations, should be prepared and submitted with the estimate. 



Definite recommendations as to what action should be taken 

 by the Forest Service. 



The detailed estimates of the cost of each proposed line should 

 cover the following points : Cost of survey, if necessary. Cost 

 per mile for clearing the right of way for the telephone line. 

 Cutting poles. Hauling poles, including distribution. Treating 

 poles with preventives ; this can be estimated at jjJLcents^per 

 J>ole^ Digging holes ; particular care should be taken in making 

 this estimate, as the cost of digging in solid rock, cemented 

 gravel, or hardpan is much more than in earth ; in^earth the 

 holes will cost about 20 cents each ; iaJJae other^materials much 

 more fwnere" powder will be used this can be estimated sep- 

 arately or included in the cost of digging. F.rppfing pplps; 

 the ayerageprice is 20 centsjjer pole. Stringing the wire; t5e 

 average cost is $5jper mile for ground lines, and $8 per mile 

 foF^mgalilc circuit CosT of "wire, orac^ets, and insulators at 

 shipping points. Cost of hauling material from railroad to point 

 where it will be used. Number and cost otjastmnients, allow- 

 ing one instrument at each Forest officer's headquarters, at look- 

 out stations, and at other necessary points; the average cost, 

 inclu.(fling freight, will be about $13 each. In making estimate 

 allow for enough extra wire, insulators, and brackets to enable 

 each Forest officer's headquarters to have a small siipply__pn 

 hand for repairs. 



. DRIFT FENCES. 



It is desired that Forest officers consider the need for drift, 

 division, or boundary fences on the National Forests, and in 

 all cases where the constructioiv-Qf such fences would be ad- 

 vantageous in controlling stock grazed under permit, or in the 

 prevention of trespass, a report and recommendation including 

 a map showing the location of the fences, and a definite estimate 

 of their probable cost should be submitted to the Forester.
