NATIONAL FOREST IMPROVEMENTS
The Need of Improvements. It is but natural, from their situation, that the National Forests represent pioneer conditions; conditions that one might expect to find in a wild, rugged, mountainous country. This was true to an extreme degree when the National Forests were first established and it is true in a very large degree even to-day, since the amount of time and money which it will be necessary to expend on the construction of improvements on the 155,000,000 acres of National Forests is something enormous. For a long time to come, then, the National Forests will need improvements in order to make them secure against fire and in order to make the resources, now locked up, available. Proper protection and the fullest use of National Forest resources depend mainly upon facilities for transportation, communication, and control. All parts of the National Forests should be accessible by roads and trails; there should be telephone communication between settlements and Forest officers' headquarters and with the lookout stations; and in most cases suitable living accommodations must be provided for the field force. For the fullest use of the forage resources, water for the live stock must be developed and range fences constructed; to reduce the hazard and the cost and difficulty of controlling forest fires, firebreaks and other works must be constructed.
Transportation Facilities. Adequate facilities for travel and transportation are of first importance. Steam roads, electric roads, and boat lines are utilized in the National Forest transportation system as well as the existing roads and trails. Added to this, new roads and trails are being constructed every year to complete the already existing network.

The need for new roads and trails depends upon the number of them already existing, the value of the resources that it is necessary to make accessible, the fire liability, and the amount of unrealized revenues due to lack of transportation facilities. If valuable grazing land or timber land can be made accessible there is good reason for building a new road. In many cases roads and trails are built to facilitate the protection of large remote areas from fire. Such areas may have large bodies of valuable timber which if destroyed by forest fires would involve a heavy loss. Even aside from valuable timber on an area, it is absolutely necessary when a forest fire breaks out to get to it with men and fire-fighting equipment in the shortest possible time before it spreads. If the fire gets to be a large one, many men with provisions, tents, fire-fighting tools, and other equipment must be transported to the scene of the fire. Any delay in the transportation of these things may prove fatal and may result in an uncontrollable conflagration.
The transportation system that is proposed for a National Forest, if the one that exists is inadequate, is usually planned many years ahead. The ultimate or ideal system is always kept in mind so that every mile of road or trail that is constructed is made a part of it. If not enough money is available for a good road, a trail is built along the line of the proposed road. Later this trail is widened into a permanent road. The Engineer connected with each District Office usually has charge of laying out big road projects. A few miles of permanent, good, dirt road with good grade is always preferred to many miles of poor road with heavy grade and improper drainage. A road and trail system is planned for each National Forest which will eventually place every portion of the Forest within a distance of at least 7-1/2 miles of a wagon road. A pack-train can then transport supplies from the point to which they are delivered on the wagon road to any field camp and return in a single day.
In trail and road construction it is very often necessary to build bridges. Sometimes a very simple log bridge meets the need, but in bridging many large mountain torrents, which become very high and dangerous in the spring, large bridges are necessary. Cable suspension bridges and queen and king truss bridges are built where occasion arises for them, but only after being planned in detail and after the District Forester has approved their design and method of construction.
