 CANYONS. THE LIGHT AREAS ARE ROCK OUTCROPS. 



sible a great deal of rock work can be 

 done. The two materials used for 

 blasting are dynamite, which costs from 

 10 to 15 cents per pound, and black 

 powder, which is about the same price. 

 Dynamite when exploded works in- 

 stantaneously with a sharp shock, while 

 black powder works slower and exerts 

 more of a shoving force. The cost of 

 rock work varies from $ .50 to $1.50 

 per cubic yard. 



In general in building trails the coun- 

 try should first be reconnoitered and the 

 route fully decided upon. The trail 

 should then be located by stakes or 

 blazes and the route cleared and brushed 

 out to the specified width. The grading 

 work should then be done and the tread 



made the specified width. Signs show- 

 ing the distance from important points 

 and from water should be put in every 

 mile if possible and never less than 

 every 4 or 5 miles. 



ROAD CONSTRUCTION. 



The use of a road largely determines 

 the amount of work which should be 

 done upon it. Freight roads and stage 

 roads as a rule should be well worked 

 and kept in good condition and if there 

 is a great amount of traffic they should 

 be double tracked or turn-outs made 

 along the way, while for logging pur- 

 poses it is not so necessary to have a 

 well worked road, as it is only used
