A great many pulp and paper investigations are also conducted by this Laboratory. The large size of the industry and the threatened exhaustion of the native spruce forests which furnish the princ.i.p.al supply are circ.u.mstances which call for intensive investigations. About nine-tenths of the paper which we use is made from wood, and the amount of wood which is converted into paper annually has reached almost 5,000,000 cords. There are over 2,500 newspapers in the United States, and it is said that a single issue of a New York Sunday paper consumes the trees on about 15 acres of forest. The main object of the work at the Laboratory has been to use other species of wood for the manufacture of paper to offset the fast waning supplies of spruce. Poplar, hemlock, pine and balsam are now being used in considerable quant.i.ties. News and wrapping paper has also been successfully made from many National Forest species, including Sitka spruce, Western hemlock, Engelmann spruce, Red fir, White fir, and Lodgepole pine. Kraft paper has been made and manufactured into suitcases, bags, wall coverings, twine, and similar articles. Not only has the Forest Products Laboratory brought into use species of trees never before tried for paper making, but it has also improved some of the old methods of paper making to such an extent that the results have been adopted by various large paper mills.
Many strength tests are conducted with packing boxes. The railroad companies of the United States are paying annually claims amounting to many millions of dollars because of goods damaged in s.h.i.+pment. Much of the damage is preventable through properly constructed boxes. Tests conducted at the Laboratory have shown for canned-food boxes an increase in strength of 300 per cent, by the use of four additional nails in each end of the box. The results of these tests are being rapidly adopted by manufacturers and canners.
The dyeing principle of the Osage orange wood was not used prior to the investigations conducted by the Laboratory. The value of this material has been so conclusively shown that about one million dollars' worth of the dye is now being manufactured annually in the United States and practically all from material which was formerly wasted.
The discovery that sodium fluoride is superior to sodium carbonate in preventing sap stain in lumber promises to reduce materially the present estimated loss of $7,000,000 from this cause.
_Industrial Investigations._ The function of the Office of Industrial Investigations of the Branch of Forest Research is to conduct statistical and industrial studies of uses of wood in the United States.
The aim of these investigations is to determine methods and conditions under which wood is now used; the marketable products obtained from it; tendencies in methods of manufacture; and improved methods possible, especially in the utilization of waste. When practicable, such investigations are followed by the commercial application of their results. This office also conducts all statistical investigations of the production and use of forest products.
The work of industrial investigations includes the following: collection and compilation of statistics on the production and consumption of forest products, prevailing market and stumpage prices, imports and exports, and transportation rates; the compilation and study of specifications of rough and manufactured forest products; studies of lumber manufacture and wood-using industries as to methods, forms of material, waste, costs, equipment, subst.i.tution of one species for another, and improvements through a more conservative use of raw material; studies of special problems or features of wood-using industries; advice and a.s.sistance to States, industries and individuals along such lines of work; and the dissemination of results by publications.
Many studies in wood utilization are made not only of certain industries like the s.h.i.+ngle, or the lumber industry, but also dealing with the industries of particular sections of the country and with the various States. These investigations in the States show the kinds and amounts of woods required by the various industries, the purposes for which the various species are employed, and the extent of their use. So far the wood-using industries of 35 States have been studied and the results published.
Records of lumber prices for important woods are compiled quarterly.
These figures are useful in establis.h.i.+ng timber sale prices on the National Forests. Statistics as to the annual consumption of lumber in the country are also compiled by this office.
The wood waste exchange was established in 1914 by the Forest Service.
It consists of two lists of manufacturers, which are sent out quarterly to persons desiring them. One of these is of "Opportunities to Sell Waste" and contains the names of firms which use sawdust and small pieces of wood. This list is sent to people having waste for sale. The other list is of "Opportunities to Buy Waste," and gives the names of concerns which have waste to dispose of. This list is sent to people who wish to buy material. No charge is made for this service, and at the present time over 500 cooperators are using this exchange.
By the use of this exchange, makers of wooden novelties have been successful in finding supplies of material near their plants. Other wood-working industries have been able to dispose of their waste at higher prices than they could otherwise have obtained. Many firms were located within short distances of each other, but until recently have had no way of getting together. A Philadelphia firm, engaged in the manufacture of composition flooring, has been able to obtain a portion of its sawdust from a New York lumber company. A New York woodworking establishment disposed of its waste pieces of white oak and sugar maple to a maker of wooden novelties in Connecticut for use in the manufacture of furniture k.n.o.bs. A clock maker of Connecticut secured waste material for making clock boxes from the planing mill of a New York lumber company.
CHAPTER III
THE PROTECTION OF THE NATIONAL FORESTS
The resources of the National Forests may be injured or destroyed in many ways. Fire may burn the timber and young growth; insects and tree diseases may damage or kill timber, and certain persons may innocently or willfully commit trespa.s.s on National Forest land and use the resources without permit. Then also, the fish and game of the Forests must be protected from unlawful shooting and trapping, and the water issuing from National Forest streams must be kept free from pollution, to protect the public health.
PROTECTION FROM FIRE
_Forest Fire Danger on the National Forests._ Practically all the resources of the National Forests are subject to severe injury or even to entire destruction by fire. It is an ever-present danger on the National Forests, due to their great inaccessibility, their dry climate, and to other unfavorable conditions. There are probably few forest regions in the world where the danger of fire is greater than on the National Forests. The great size of the individual Forests, as compared with the size of the available patrolling force, the difficulty of reaching remote areas across miles of wilderness, the dry air and light rainfall in most parts of the western United States, the prevalence of lightning storms in the mountains, the spa.r.s.eness of the population, and the constant use of fire in the industries and the daily life of the people, all combine to make the hazard exceptional.
_Importance of Fire Protection._ Forest fires when uncontrolled mean the loss of human lives, the destruction of homes, live stock, forage, timber and watershed cover. Besides the direct damage to the National Forest resources it defeats all attempts to practice forestry; it nullifies all efforts of forest management, such as regulation of cutting to insure a second crop of timber, the planting of denuded areas, and the restriction of grazing to a.s.sist reproduction. Fire destroys the very improvements which are constructed annually at great expense. In other words, protection from fire is the first and most important problem on the National Forests without which no operation or transaction, however small, can be undertaken.
If the problem of fire protection is the most important task confronting a Forest officer on the National Forests, then certainly fire prevention is next in importance. Obviously it is easier to prevent fires than to fight them. All large conflagrations have their origin in small fires which if they could be reached in time could probably be put out by one man. But in regions remote from water and supplies fires may start and reach vast proportions before a party of fire fighters can get to the scene, no matter how promptly the start is made. By far the best plan, therefore, is to prevent fires rather than to depend upon fighting them after they get started. To this end the Forest Service has given the most earnest consideration. During the dangerous season the main attention of Forest Supervisors and Forest Rangers is devoted to preventing fire. Extra men are employed, the Forests are systematically patrolled, and a careful lookout is maintained from high points. Roads and trails are so built that every part of the Forests may be quickly reached with pack animals. Tools and food for fire fighters are stored at convenient places. The Ranger stations and lookout houses are connected with the office of the Forest Supervisor by telephone, so that men may be quickly a.s.sembled to fight a dangerous fire which the patrolman cannot subdue alone. Each Forest Supervisor endeavors to secure the cooperation of all forest users in the work of preventing fires and in reporting and helping to fight them in case they get started.
Probably the beginning point of any discussion of forest fires is a consideration of their causes. The Forest Service has kept careful records year after year (by calendar and not fiscal years) concerning the cause, the damage, the area burned over, the cost of fighting and many other matters. During the calendar year 1917 there were 7,814 forest fires on the National Forests. Of these the National Forests of California had to contend with 1,862. Of the total number of forest fires 40 per cent. were confined to less than 1/4 of an acre, 28 per cent. to less than 10 acres, while 32 per cent. spread over areas greater than 10 acres. The large percentage of small fires shows how efficiently the National Forest fire protection organization works in keeping the area burned over to the lowest possible acreage.
_Causes of Forest Fires on the National Forests._ Forest fires on the National Forests originate in many different ways. In 1917, lightning caused 27 per cent.; unknown agencies, 17 per cent.; campers, 17 per cent.; incendiaries, 12 per cent.; railroads, 13 per cent.; brush burning, 7 per cent.; saw mills, 3 per cent., and all other causes, 4 per cent. Thus it will be seen that a very large percentage, at least 60 per cent., of the fires are attributable to human agencies and are therefore preventable. At least 27 per cent, of the fires, those attributed to lightning, are not preventable, and the only way to combat those is for the Forest officer to get to them as soon as possible after they get started. The preventable fires, however, may be arrested at their source, that is, by popular education dealing with the use of fire in the woods these causes can be greatly reduced and, in time, no doubt, eliminated. Therefore, the fire protection problem immediately resolves itself into two almost distinct phases of action--fire prevention and fire control.
[Ill.u.s.tration: Figure 34. A forest fire lookout station at the summit of Mt. Eddy. Mt. Shasta in the background, California]
Just how these various agencies start fires may be of interest.
Railroads cause fires by their locomotives sending out sparks through the smokestack or dropping hot ashes along the right-of-way. These sparks alight in inflammable material, such as dry gra.s.s and leaves, and start a fire. Lightning sets fire to trees, especially dead and dry ones. In the California mountains, lightning storms without rain are frequent and these do great damage. The author has seen as many as nine forest fires started by a single lightning storm inside of half an hour.
Incendiary fires are set by people with varying intent. How many are set with malicious intent, just to see the forests burn, is not known, but many fires are started by people setting fires to drive game, to improve the pasture, to make traveling through the woods easier, or for other reasons. Brush burning includes those fires which start from settlers clearing land and burning the brush and thickets. Campers cause a large percentage of the fires by leaving their camp fires burning. Instead of extinguis.h.i.+ng them before they leave camp, careless people let them burn; a wind blows a few sparks into some dry leaves or gra.s.s nearby, and the fire is started. Many forest fires also start around logging camps by sparks escaping from logging engines, or by setting fire to the slash that is left after logging and allowing these fires to get beyond control.
_Behavior of Forest Fires._ Fires behave differently, once they get started, depending upon the character of the timber, the amount of wind, and the degree of inflammability of the forest cover. Ground fires burn the inflammable dry gra.s.s, needles, dead twigs, etc., on the ground; crown fires are much more severe and, being usually fanned by a heavy wind, run through the tops or crowns of the trees; brush fires burn the bushes and dry shrubs from 5 to 10 feet high; timber fires consume the entire forest--crown, stem, ground cover, and undergrowth--and usually occur in timber that stands close together.
_Losses by Forest Fires on the National Forests._ The results of forest fires naturally vary with the kind and intensity of the fire. Crown and timber fires do the most damage, and ground and brush fires do less.
While the ground fires and brush fires seem to do very little damage to the valuable timber, still they may greatly reduce the productive power of the soil and destroy the watershed cover. Severe ground fires may kill valuable timber by girdling the trees. The great fires of August, 1910, which swept northern Idaho and western Montana destroyed millions of dollars' worth of timber and 85 human lives, and cost the United States $839,000 for fire fighting. These were timber fires and they occurred for the most part in valuable stands of dense timber.
The forest fire losses on the National Forests for the last 9 years show a very great and gradual reduction of losses due to forest fires.
In 1908, the total loss through fires was $451,188 and in 1909 it was $297,275. In 1910, the year of the great fires in Montana and Idaho, there were very heavy losses in timber and human lives, due to an unusual combination of dry weather and high winds. But in that year the fire organization was not complete; it had never really been tried out. In this year the organization received its first severe test, and while it did the best it could with the available men and equipment, the situation in Idaho pointed out conclusively the weak points and the short-comings. The proof of these statements is found in the statistics of the next 5 years, when the average total loss for 1911 to 1915, inclusive, was $293,000, and, it must be remembered, several of these years were equally as unfavorable, so far as dry weather and high winds were concerned, as the year 1910. During these years, however, the fire fighting organization had a good chance to be tried out thoroughly; for, as is quite evident, experience is the greatest teacher in this kind of work. During the calendar year 1916 the fire losses reached a new low level, compared to other years, the losses amounting to only $198,599.
In 1917 they were higher.

_The Forest Fire Problem Stated._ Having seen a little of the causes, behavior and results of forest fires on the National Forests, it is comparatively easy to state the forest fire problem as it occurs on the National Forests. Briefly stated, it is this: With the funds, organization and equipment that are available, the aim of the Forest Service is to keep the area burned over each year (and therefore the damage done) down to an accepted reasonable minimum. But the problem is not as easily worked out as it is stated, due, largely, to a great many uncontrollable and variable factors which cannot be foreseen in advance, the most important of which are the weather conditions. As has been said before, there are two general ways of keeping the area burned over down to an accepted reasonable minimum: either prevent the fires from getting started (as in the case of those started by human agencies) or, after they get started, to get to them with men and fire fighting implements in the shortest possible time after they are found.
The former is called fire prevention, and the latter fire suppression or control. How the organization of the National Forests solves these two problems is of the greatest interest.
_Fire Prevention._ The measures employed for fire prevention may be either administrative, legislative or educative in nature.
The most important administrative measures employed to prevent fire are those that aim to reduce the amount of inflammable material in the National Forests. This is done in many different ways. The free use timber policy enables Rangers to give away much dead timber, both standing and down. Timber operators cutting on the National Forests are required by the Forest Service contract to remove dead snags, which are a fire menace, from the timber sale area. Where there is fire danger, all slas.h.i.+ng resulting from such sales must be burned or otherwise disposed of. While grazing is usually not considered a measure to prevent fires, still gra.s.s lands that have not been grazed over become very dry in the fall and are a dangerous fire menace. Wherever it is feasible, old slash left by lumbermen on private lands adjacent or near to the National Forests are burned, when the fire can be confined to a small area. Another administrative measure is the reduction of the causes of fires by a patrol force. Forest Guards travel along the highways where there is most traffic and most danger. Their presence often is enough to remind campers, hunters and fishermen to put their camp fires out before leaving them. These patrolmen mix with the people and, if necessary, remind them in a courteous way to be careful to extinguish their camp fires before breaking camp.
Most of the necessary legislative measures for preventing forest fires already exist. The National Forest force is seeking merely to obtain a strict enforcement of existing laws. Railroads are required to use spark-arresters on their locomotives and to provide for keeping their rights-of-way free from inflammable material. Logging camps must also prevent the destruction of National Forest timber by fire by using spark-arresters on all logging engines. The Forest officers are ever on the alert for the detection and apprehension of campers for leaving fires unextinguished and incendiaries for starting fires willfully.
These careless individuals are arrested by them without warrant, either under the Federal laws, if the fire occurred on National Forest lands, or under the State law, if it occurred outside of government lands.
Educational measures are for the purpose of educating both the local forest-using public and the general public who may travel through the Forests in the careful use of fires in the forests. Forest officers, especially Rangers, come into personal touch with local residents and users, that is, the ranchers, stockmen, business men, loggers, campers, hunters, fishermen and others. Such people are often reminded by personal appeals by the Forest officers. Most of them have learned by this time, because of having been called upon to help fight fires at one time or another, and having gotten a taste of the result of other people's carelessness. Many written appeals are also sent out by the Supervisor and are slipped into the envelopes when grazing permits and other official doc.u.ments are mailed. One of these written appeals, and probably the one that has been used most widely, is known as the six rules for the prevention of fires in the mountains:
1. Matches.--Be sure your match is out. Break it in two before you throw it away.
2. Tobacco.--Throw pipe ashes and cigar or cigarette stumps in the dust of the road and stamp or pinch out the fire before leaving them. Don't throw them into the brush, leaves, or needles.
3. Making camp.--Build a small camp fire. Build it in the open, not against a tree or log, or near brush. Sc.r.a.pe away the trash from all around it.
4. Leaving camp.--Never leave a camp fire, even for a short time, without quenching it with water or earth.
5. Bonfires.--Never build bonfires in windy weather or where there is the slightest danger of their escaping from control. Don't make them larger than you need.
6. Fighting fires.--If you find a fire try to put it out. If you can't, get word of it to the nearest United States forest ranger or State fire warden at once. Keep in touch with the rangers.
Besides these kinds of appeals, many kinds of fire warnings are posted at conspicuous places along roads and trails to remind the public to be careful with fire in the Forests.

The streams are used for water power, domestic purposes, and for irrigating many of the largest lemon and orange groves of southern California.]
[Ill.u.s.tration: Figure 38. A forest officers' temporary camp while fighting forest fires. Near Oregon National Forest, Oregon.]
An attempt is also made to reach the general public, that is, those living outside the local communities, but who occasionally travel through and use the National Forests. Many hundreds of thousands travel through the Forests every year by automobile or by other conveyances. These people camp in the Forests, fish, hunt, and enjoy the cool climate and beautiful scenery. Before they start on their trips, that is, while they are still in their home towns, and also while they are on their way, many means have been devised to reach them. They are confronted with newspaper advertis.e.m.e.nts, folders, booklets, and other printed matter. In towns and cities, public meetings, lectures, exhibits, expositions, county fairs, commercial clubs, and the chambers of commerce, all help, either directly or indirectly, by one means or another, to inform the people of the great fire danger on the National Forests. Even the letters sent out by the District Forester and the Supervisors have written appeals affixed to the outside of the envelopes by means of a rubber stamp. In short, every possible means is used to educate the public that uses the National Forests and in whose interest, in fact, the Forests are being maintained and protected.
_Fire Suppression._ So much for the problem of fire prevention. In case a fire does get started, and there are thousands of them on the National Forests every year, the problem, as has been said before, consists of getting men and tools to it in the shortest possible time, in order to keep the damage down to the lowest possible point. To do this, a vast organization has been formed by the Forest Service, which is not unlike the Minute Man organization of Revolutionary days. A brief outline of this organization and how it works when a fire starts will give my reader a still better idea of what the Forest Service is doing in forest fire protection. But before speaking of this organization, a few preliminary matters are of interest; they deal with the manner of distributing fire protection funds, forest fire history, and the study of weather conditions.
