properties and resources and in their use by communities and the 

 Nation. The Federal highway act of November 9, 1921, made it 

 possible for the the Forest Service to cooperate in the building of 

 State or county roads traversing national forests which form a link 

 in State or county highway systems. 



2. What is the forest-highway system? 



A system selected by the highway department of the State in which 

 the national forests are located, in cooperation with the Bureau of 

 Public Roads and the Forest Service, and approved by the Secretary 

 of Agriculture. This system includes portions of the United States 

 highway system and Federal-aid system and is of great importance 

 both to the traffic on these systems and in making the national for- 

 ests accessible. The forest-highway system of California now con- 

 sists of 2.546 miles. 



3. What is the forest-development roads and trails system? 



A system of roads and trails required for the administration, pro- 

 tection, utilization, and development of the national forests, as desig- 

 nated by the Forester. There are 15,133 miles of development roads 

 and 20.102 miles of development trails in the California national 

 forests. 



4. How much money is spent each year on roads and trails in the 

 national forests of the California region? 



The average for eight years, 1923 to 1930, inclusive, including the 

 1(> per cent fund, was approximately $1,500,000. Funds expended 

 directly by the Forest Service are spent on the less expensive projects 

 for administration and protection of the national forests and come 

 from the forest-development fund. Aid to the State and counties on 

 essential links in the highways systems comes from forest-highway 

 funds, the engineering work being done by the Bureau of Public 

 Roads. 



5. Are advertising signs and billboards permitted on Forest Service 

 roads and trails? 



No; except when authorized by permit, which will be issued only 

 when the proposed sign contains distance, directional, or informa- 

 tional data of value to the traveling public which can not otherwise 

 be supplied, and does not impair or detract from the scenic beauty of 

 forest lands. 



6. What is a motor way? 



A motor way is an inexpensive road opening up to motor transpor- 

 tation an area or section of the national forest where fire hazard 

 exists. It is a means of getting quicker action on fires in isolated 

 localities, and also acts as a firebreak. 



7. Why are motor ways and other national-forest roads often 

 closed to public travel? 



Forest Service roads may be closed, in times of unusual weather 

 conditions which create a high fire hazard, and during the winter 

 months to prevent the surface of the road from being torn up by 

 traffic when the roadbed is soft.
