There are different kinds of fires, depending upon their size, their intensity, and the nature of the country in which they are burning. And there are as many different methods of fighting fire as there are kinds of fires. Some fires, such as grass fires or those burning in the needles and litter in the forest, can be extinguished directly by being smothered or beaten out. For this purpose Rangers sometimes use their saddle blankets, when nothing else is handy, but usually wet gunny sacks, boughs, and tree branches are used. Often, if it is available, sand or dirt is thrown on the fire with a shovel. Surface fires are a little more difficult to extinguish. They are more intense and more swift and consume brush, young growth, and fallen dry trees. These usually cannot be attacked directly, but must be controlled indirectly by the building of a trench or a fire break, or by a system of back firing. Trenches are fire breaks in miniature, usually from one to several feet wide. Fire breaks or fire lines are broad belts from 30 to 50 feet wide, which are cleared of inflammable material, not so much to stop the fire when it reaches this belt as to furnish a safe area from which fire can be fought and, most of all, from which back firing can be started. These lines or belts are usually built along ridges. If a fire starts on the lower slope of a mountain and the wind carries it up the mountain toward the fire line, the only hope of stopping the fire at the top of the ridge at the fire line is to start fires on the top of the ridge, which will burn down the slope and meet the original fire coming up. In rare cases, as, for instance, in the Idaho fires of 1910, the fires get to be so large and swift that all methods of attack prove futile and the only salvation is in natural barriers, such as rivers, or a change of the wind, or rain, to extinguish them.

In all fire fighting work, the plan is to surround the fire (if it cannot be beaten or smothered out) by a trench, fire line, or fire break, and to prevent the fire from spreading. In this kind of work, shovels, spades, mattocks, rakes, and hoes are used to move the soil; saws and axes are used to remove fallen trees from the fire line, and in some cases plows, dynamite, and other implements are employed.

PROTECTION AGAINST TRESPASS, FOREST INSECTS, EROSION AND OTHER AGENCIES

While the protection of the Forest resources from fire is probably the most important phase of forest protection, it is not the only one by any means. The National Forest force also protects the Forest resources from trespass, from insect damages, and from tree diseases. Also water supply for domestic use, for irrigation, water-power, and navigation must be protected, and the public health must be safeguarded against the pollution of the streams emerging from the Forests. It is also the duty of Forest officers, in coöperation with the state authorities, to protect game, fish, and birds from illegal practices.

Trespass. The Act of June 4, 1897, authorizes the Secretary of Agriculture to make rules and regulations for the occupancy, use and protection of the National Forests, and provides that any violation of such rules and regulations shall be punishable by a fine or imprisonment or both. This and later acts provide for fines or imprisonment for all violations of the regulations governing National Forests. The violation of these regulations constitutes trespass, and these may be either fire, timber, grazing, occupancy or property trespass, depending upon the offense. Since the United States has all the civil rights and remedies for trespass possessed by private individuals, it may bring action to recover damages resulting from trespass or breach of contract.

Fire trespass includes the following offenses: setting fire to timber, brush or grass; building camp fires in dangerous places where they are hard to extinguish; or leaving camp fires without completely extinguishing them. The various railroads that cross the National Forests are one of the most frequent offenders in that the sparks issuing from the locomotives or the hot ashes dropping from the fire box set fire to National Forest timber. The railroads are required to use every precaution to prevent such fires, but many of them are started, resulting in damage suits by the Government. The damages cover not only the merchantable timber and forage destroyed, but damages are also collected for young, immature growth, which at first thought might seem to have little or no value. But the courts have held that while the young, unmerchantable trees have very little value now, they have a great value as the basis for a future crop of timber. Thus, in the case of the United States versus the Chicago, Burlington and Quincy Railroad, in 1910, for fire trespass on the Black Hills National Forest, caused by sparks from the locomotives operated by the company, the damages included $17,900 for young growth. Also, in the case of the United States versus the Great Northern Railroad, in 1911, in which suit was brought upon the negligence (causing fires to start) of the defendant company on their right-of-way, which fires subsequently spread to the Blackfeet National Forest, damages included the destruction of a great many immature trees, the value of which was estimated on the basis of their value at maturity discounted to date. It is significant that this case never went to trial; the defendant paid damages and costs without argument.
