second blazing at a higher point after the deep snow 

 renders this convenient. 



It is often desirable, as in the case of trails, that 

 Forest Service blazes should be distinguished from 

 land office blazes or from private surveys, and, there- 

 fore, a distinctive blaze has been adopted for the 

 Forest Service. This is the width of an ax blade, 

 about 6 inches long, with a horizontal notch at the 

 top of the scar. 



The Forest Service has also adopted a distinctive 

 mark to indicate the intersection of one of its lines 

 with a land office line and to show the approximate 

 distance to the nearest land office corner. Thus, 

 when a road or trail crosses a section line a tree may 

 be marked in such a manner that any Forest officer 

 may recognize it, and will know the direction and 

 approximate distance to the nearest section or quarter- 

 section corner. This mark is made in the following 

 manner: A tree near the point of intersection is 

 barked to the wood, about 8 by 10 inches, on the 

 side facing the corner. A letter C with horizontal 

 crossbars is then scribed upon the scar. A horizontal 

 bar will indicate that the distance to the corner is 

 about 10 chains, and each half bar will indicate a 

 distance of about 5 chains. For example, the inter- 

 section marks may read as follows: 







About 5 About 10 A b o u t 15 A b o u t 20 A b o u t 25
