thorough study by the supervisor or a competent forest officer 

 whom he may designate, of the efficiency of lookout points, be- 

 fore new points are selected and towers erected. Generally it 

 may be said that every forest has a few prominent peaks and 

 they have been selected as lookout stations as a rule. What is 

 wanted is to know accurately whether these points already se- 

 lected really cover the areas they are supposed to. To deter- 

 mine this, go to a lookout point and take bearings on all prom- 

 inent points in the area covered by the lookout, as well as bear- 

 ings in canyons and on natural boundary features, making an 

 estimate of the distance to all such points and plot them on 

 the map so that a meander line can be drawn around the 

 "seen" area. Where nearby ridges or other small peaks are 

 so located as to interfere with fires on their far sides being 

 readily discovered, special note should be made of these con- 

 ditions, so that they can be checked from other lookout points. 

 If after checking the area of efficiency of all lookout points, it 

 is found that there are certain areas that can not be seen from 

 any of them, the advisability of establishing another primary 

 lookout or, if none is available, the location of a patrolman's 

 route will be in order. 



Fire Maps. 



The present fire map, a sample of which was sent out in 

 the spring of 1912, has been adopted as the standard fire pro- 

 tection map for the district. This means the adoption of all 

 the information as given on that map. When there is a riding 

 patrol the routes of patrol will be indicated. The organiza- 

 tion diagram will be placed on the map. The protractor should 

 be drawn directly on the tracing at each primary lookout point. 

 On the forests where the tri-colored base map is now in use or 

 where there is any reason for not placing the protractor on the 

 tracing, the transparent protractor will be pasted on the map. 

 Where there are inter-forest primary lookout points, a double 

 arc, with the projected bearings from the lookout point of an 

 adjoining forest marked on each arc, should be on the border of 

 the map, so that a correct bearing may be had from the 

 lookout point of such adjoining Forest. In order to get this it 

 will be necessary to give each Forest its proper location with
