Notes on Bark Structure 139 



the exterior boundary lines thereof which strip is particularly 

 described in the field notes attached hereto." The width of 

 the strip was not necessarily 30 feet in each instance but was 

 varied according to the purpose to be served. The starting 

 and closing points of the right-of-way were each marked by 

 a stake or stone, which were established in a manner to con- 

 form with the instruction relating to the establishment of 

 monuments and corners. It is not necessary in making right- 

 of-way surveys to mark the turning corners where angles 

 occurred in the interior of the tract recommended for listing. 



The regulations required that all the boundaries of the 

 claim should be run and plainly blazed. Any tree standing 

 exactly in the line was blazed fore and aft; those standing at 

 either side of the line or near it, were blazed on two sides 

 quartering toward the line. In blazing for a trail the blaze 

 was about the width of an ax blade, about six inches long, 

 with a horizontal notch at the top of the scar. 



In making a triangulation to determine the location of 

 an inaccessible point the field notes always contained a descrip- 

 tion of all the operations. The formula was inserted on which 

 the computations were based. 



The following marks are examples of those that were 

 most commonly used: 



F. S. M. = Forest Service Monument. 



R 



- Corner one of the ranger station survey. 



H 



- = Corner two of homestead survey.
