CHAPTER II. The Administration of the National Forests

THE ADMINISTRATION OF THE NATIONAL FORESTS

Under the head of administration we must necessarily understand those factors which are essential to carry on the business of the National Forests. First of all we must consider the personnel, that is, the men that make up the organization by means of which the work on the Forests is done. Next we must learn how the money for this large enterprise is appropriated each year to carry on the work, and how it is divided up so that each National Forest gets an amount each year in proportion to its needs. Then again men and money are of little avail without tools, equipment, and supplies. The proper distribution of these to the 147 National Forests is no small business organization in itself. Lastly we must learn of the many permanent improvements which are made on the National Forests which are absolutely necessary for their proper administration, protection and use. No large constructive forestry enterprise is complete without these. They consist of the construction of means of transportation, means of communication, and living quarters for the personnel; of extensive planting of young trees to reëstablish forests which have been destroyed by fires; the carrying on of research and experiments to aid in the development of the best methods of forestry; and the classification and segregation of agricultural lands and the establishment of permanent boundaries. All these matters must necessarily be considered before we attempt to learn about the protection and the utilization of the National Forests.

PERSONNEL

Duties of Forest Officers. Forest officers are the servants of the people and they are expected to assist in every way possible those who wish to use the resources of the Forests. Their first duty is to enforce the regulations under which all permits, leases, sales, and rentals are made. These regulations cover every phase of National Forest activity and in conducting business under them they must not let personal or other interests weigh against the good of the Forests. For the good of the Forest Service their conduct must be prompt and courteous and their business methods sensible and effective. They make it their business to prevent misunderstandings and violations of forest regulations rather than to correct mistakes after they have been made.

On the National Forests there are permanent employees and temporary employees. Under the former heading come the Forest Supervisor, the Deputy Supervisor, the Forest Assistant, the Forest Ranger, Lumbermen, Sealers, Planting Assistants, and Forest Clerks. Under the latter category come the Forest Guards, the Field Assistants, and the Temporary Laborers. All permanent positions are in the classified Civil Service. Vacancies are filled from a certified list of those who have passed a Civil Service examination or by promotion from the lower ranks.

The Forest Supervisor. A Forest Supervisor is in charge of each National Forest and he plans the work of the Forest and supervises its execution. He works, of course, under direct instruction from the District Forester and is responsible to him. When the amount of business on the Forest warrants it he is assisted by a Deputy Supervisor. Both these positions are filled by the promotion of experienced men in the classified Civil Service. The Forest Supervisor's headquarters are located in towns conveniently situated with regard to the most important points in his Forest. The town is usually located on a railroad and centrally located with regard to the various Ranger districts of his Forest. His headquarters are usually the center of the system of roads and trails which covers his entire Forest. From his office also the telephone system radiates in all directions to his various District Rangers. In short, the Forest Supervisor's office is so situated that he has at all times full knowledge of all the activities of his Forest; he is therefore in a position to give advice and directions by telephone to his Rangers and other subordinates almost at any time of the day or night. Such intimate communication is of especial importance during the fire season.

Some Forests have two headquarters, one that is occupied in the winter and the other that is occupied in the summer. The summer quarters is usually most advantageously situated as far as the business of the Forest is concerned, but owing to deep snow, which seriously interferes with mail and telephone connections, a more accessible winter quarters is occupied from October to May.

The force of men the Forest Supervisor has working under him varies of course with the amount of work to be performed. The permanent force is usually from 10 to 15 men, which during the fire season may be increased to from 25 to 40 and in cases of great fire emergency sometimes to several hundred men, by the addition of temporary employees.

The Forest Assistant. The other permanent men on a National Forest are the Forest Assistant or Forest Examiner, Forest Rangers, and a Forest clerk with his assistant, the Stenographer and Typewriter. The Forest Assistant or Examiner ranks next to the Deputy and his work is directed by the Forest Supervisor, to whom he makes his reports. The Forest Assistant is the technical man of the Forest force, who upon making good is promoted to Forest Examiner. He is employed upon such technical lines of work as the examination and mapping of forest areas; reports on applications for the purchase of timber; marking, scaling, and managing timber sales; the survey of boundaries; and nursery and planting work.

Not only is a Forest Assistant called upon to perform these various lines of technical work. The very nature of the country he is in indicates that he must be an all-round practical man. He must be able to ride, pack, and drive. He must often live alone and therefore must do his own cooking, washing, and take care of other personal needs. He must be strong and healthy and capable of undergoing hardships, at least be able to stand long days of walking, climbing, and horseback riding. His various duties and the different situations that arise often call for knowledge and practical ability as a carpenter, a mechanic, a plumber, an engineer, a surveyor, and many other lines of work. Perhaps more important than his education and ability are his personal qualifications. His temperament must be such that he must feel satisfied and contented under the most trying conditions. He must be able to do without most of the comforts of modern civilization for most of the time. For these reasons the country-bred western youths are more liable to make a success of the work than the city-bred easterner.

The Forest Ranger. The Forest Ranger's position is one of the most important and at the same time the most difficult positions on our National Forests.

The Forest Ranger's headquarters are usually at the nearest business center to his district and if that is not practicable permanent headquarters are provided on the Forest. In any case his station is located as near to the center of the business activity of his district as possible. If his headquarters are centrally located in his district, trails, roads, and telephone lines lead out from his cabin to all parts of his district. His station is built and maintained at government expense and usually has, besides his living quarters, a barn, tool-house, pasture, corral, and other necessary improvements.

The Forest Ranger performs such routine work as the supervision of timber sales, grazing, free use, special use, and other contracts and permits, the carrying out of the protection and improvement plans for his district, and other administrative duties. The average Forest Ranger has a territory of from 75,000 to 150,000 acres to take care of. On June 30, 1917, there were about 1,100 Forest Rangers employed on the National Forests who were assisted by over 900 Assistant Forest Rangers and Forest Guards. The protective force was therefore about one man for every 77,800 acres or about 121 square miles.

The Forest Ranger must be a man who is physically sound and capable of enduring great hardships. He is often required to do heavy manual labor in fighting fire under the most trying conditions. For this reason he must have great endurance. They are usually men who have been brought up in timber work, on ranches or farms, or with the stock business. They are therefore thoroughly familiar with the region in which they are to be employed and especially acquainted with the rough, semi-primitive life which is characteristic of remote places in the West.

He must be able to take care of himself and his horses in regions remote from settlement and supplies. He must be able to build trails, roads and cabins; he must be able to ride, pack, and drive and deal tactfully with all classes of people. He must know something about land surveying, estimating, and scaling timber; of logging, mining laws, and the live stock business. His duties include patrol to prevent fire and trespass; estimating, surveying, and marking timber; the supervision of cutting and similar work. He is authorized to issue permits, build cabins and trails, oversee grazing business, investigate mining and agricultural claims, report upon applications, and report upon and arrest for the violation of Forest laws and regulations.

The Forest Clerk. The Forest Clerk performs the clerical work and the book-keeping in the Forest Supervisor's office. He sometimes has a Stenographer and Typewriter to assist him and to do the mechanical work of correspondence. Lumbermen are specialists who are thoroughly well versed in all that pertains to logging, milling, scaling, and cruising timber. They are assigned temporarily to Forests where need for their work arises. Scalers are men thoroughly familiar with the art of scaling or measuring logs, ties, poles, cord wood and other forest products. Planting Assistants are specialists in nursery and planting work. Their duties include the preparation of seed beds, seed sowing, transplanting and care of seedlings, and field planting. They are assigned to the Forest Service nurseries.

Temporary Laborers, Forest Guards, and Field Assistants are employed during the field season when additional work on the National Forests warrants it. Forest Guards perform temporary protection, administrative, and improvement work; Field Assistants, usually students of forestry serving their apprenticeships, are usually employed at minor technical work and timber cruising; Temporary Laborers are employed by the day or month at any kind of improvement or maintenance work.

Forest Service Meetings. A general meeting of the Forest force is usually held annually to give the Forest officers the benefit of each other's experience, to keep in touch with the entire work of the Forest, and to promote "esprit-de-corps." The time and place of the meeting depends upon circumstances, but it is usually held at a time of the year when there is least danger from fire. Often joint meetings are held with the forces of adjacent Forests. This annual meeting idea is carried through the entire Forest Service. The Forest Supervisors in each administrative district usually meet at the district headquarters once a year and the District Foresters of all the districts together with representative officers from the Washington office usually meet annually at some centrally located district office such as the one at Ogden, Utah. These meetings assist greatly in keeping all the work in the various branches of the Service up to the same standard of efficiency, in avoiding mistakes by learning the experience of others, and in correlating and summarizing work done on similar problems in widely different regions.

HOW THE FOREST SERVICE APPROPRIATION IS ALLOTTED TO THE NATIONAL FORESTS

It is, indeed, a great task to distribute the money that is each year appropriated by Congress for the Forest Service so that the Washington Office, the District Offices, and the 147 National Forests each get their just share and so that each dollar buys the greatest amount of good for the whole people without extravagance or waste. To do this a large organization has been built up composed of business men who have absolutely no selfish interest at heart and among whom graft or favoritism is unknown and unheard of. It may be said without exaggeration that the business of the National Forests is on a thoroughly sound and efficient basis.

Forest Service Expenses. While for reasons already spoken of, the cash receipts are considerably below the expenses for running the Forests, the rapidly increasing system of roads, trails and telephone lines points not only to a constantly increasing use and service to the public but also as a consequence to increased financial returns.

The expenses of the Forest Service on the National Forests are of a two-fold character. There are costs of administration and protection on the one hand which might be called ordinary running expenses, and the costs of improvements, reforestation, and forest investigations on the other. The latter are really in the nature of investments, and do not properly fall into the category of operating costs. Yet they are absolutely necessary to the welfare of the Forests. They comprise expenditures for roads, trails, telephone lines, and similar improvements, the establishment of forests by the planting of young trees which have been destroyed by past fires, the carrying on of research and experiments to aid in the development of the best methods of forestry, and expenses connected with the classification and segregation of agricultural lands in the Forests. The establishment of permanent boundaries and the cost of making homestead and other surveys are also in the nature of investments. Such expenditures may be looked upon as money deposited in the bank to bear interest; they will not bring direct financial returns now but will produce great revenue many years hence.

The Agricultural Appropriation Bill. The fiscal year in the Forest Service extends from July 1 of one year to June 30 of the next. Every year, in the Agricultural Appropriation Bill that comes before Congress, there is an appropriation for the Forest Service for its work. This appropriation is not in a lump sum but by allotments or funds. There is the fund for Fire Fighting, one for General Expenses, another for Statutory Salaries, another for Improvements, another for Emergency Fire conditions, and usually there are special appropriations for various purposes. For the fiscal year 1918 (extending from July 1, 1917, to June 30, 1918) there are special appropriations for Land Classification, for purchasing land under the Weeks Law, for coöperative fire protection under the Weeks Law, and for the Federal Aid Road Act.

The Ranger's Protection and Improvement Plans. Long before this bill reaches Congress every Forest Ranger on every National Forest, every Forest Supervisor, and every Branch of the Washington and the District Offices have been estimating how much money they will need to carry out the plans proposed for the next fiscal year. Each Forest Ranger works and studies over his plans for the next year with which he hopes to protect his district from fire. He plans and figures out what improvements are urgently necessary to make the remote parts of his district more accessible. He tries to arrive at a safe estimate of the cost of so many miles of trails, roads, and telephone lines, so many cabins, barns, corrals, etc., which he thinks are absolutely essential to the proper administration of his district, and he estimates the number of Forest Guards, lookout men, and patrol men he will need for the protection of his territory. Usually these items are summed up under his annual Improvement Plan and his Protection Plan respectively.

The Supervisor's Plans. When the Forest Supervisor receives such estimates and plans from each of his Forest Rangers he studies them over carefully and tries to decide in an impartial way what improvements are most necessary in each Ranger district and what additional men are necessary for the adequate protection of the region in question. He carefully weighs the arguments for and against each expenditure and decides what improvements must be made now and which ones it would be possible to postpone for one or more years without detriment to the work of his Forest as a whole. For in most cases the amount of necessary work to be done on each Ranger district is far in excess of the amount which the Forest Supervisor could approve owing to the inadequacy of the Forest Service funds. So, for the Forest Supervisor, it is merely a question of how low he can keep his estimates for money for the ensuing year until such a time when Congress will appropriate more money so that all the important and necessary work can be done. In most cases therefore the major part of all the expenditures recommended by the Forest Ranger is warranted, but the Forest Supervisor knows that he must cut all the estimates down considerably in order to bring the total Forest estimate reasonably near the amount he is likely to get, basing his judgment upon what he got the year before.

Approval of Plans by the District Forester. The District Forester then gets the National Forest estimate from every one of his 25 or 30 Forest Supervisors and he in turn must decide what projects on each Forest are immediately necessary and which ones can be postponed. The same process is repeated in the Washington office when all the estimates from the District Foresters are received, and the Forester in turn sends to the Secretary of Agriculture his estimates by allotments or funds, which in turn are put before Congress. While Congress sometimes makes minor changes in the Forest Service appropriation, in most cases the bill is passed as it stands.

The District Fiscal Agent. The money appropriated by Congress is allotted to each district, and in turn to each National Forest and finally to each Ranger district by funds, such as General Expenses, Fire Fighting, Improvements, etc. In each district the financial matters are taken care of in the Office of Accounts by the District Fiscal Agent. He is the Assistant of the Chief of the Forest Service Branch of the Division of Accounts of the Department of Agriculture and pays all the bills incurred by the district and receives all the money which comes in from the sale of National Forest resources. The amount of money appropriated for the district is credited to him and he disburses this appropriation in accordance with the Fiscal Regulations of the Department of Agriculture. No other officer is allowed to receive money for the sale of timber, forage, or other resources; in fact no other official in the District handles any of the Forest Service funds whatsoever.

All remittances by users of the National Forests are made to the U. S. District Depository. If a rancher has bought some timber from a Forest Ranger, he is given a letter of transmittal showing the amount of the purchase which he must send to the District Fiscal Agent with the amount necessary to pay for the timber. The letter of transmittal explains the purpose of the remittance.

Tax Money Paid to the States. Another interesting feature of the National Forest business is the money paid each State out of the annual receipts in lieu of taxes. It must be remembered that National Forests do not pay taxes to the States in which they are located. On the other hand, if the National Forests were private property they would bring into the county and state treasuries yearly taxes. To compensate the State for the taxes lost in this way each National Forest pays to each county in proportion to the area of the National Forest lands located in that county a sum of money equal to 25 per cent, of the total gross receipts each fiscal year. From the receipts of the fiscal year 1917 this amounts to about $850,000. It is provided that this money is to be expended for schools and roads in the county in which the National Forests lie. Recently a law was passed giving the Secretary of Agriculture authority to expend an additional 10 per cent. of the National Forest receipts for the construction of roads and trails for the benefit of local communities. From the fiscal year 1917 this amounts to about $340,000. These moneys for roads, trails, and schools are of course a great benefit to the mountain communities, since usually the amount of taxable property in such remote localities is small and hence the amount of taxes received is small. These allotments to the counties have helped to develop the communication systems of local communities and have also made the National Forests more accessible and useful.

THE EQUIPMENT AND SUPPLIES FOR THE NATIONAL FORESTS

The Property Auditor and Property Clerk. The depot for equipment, supplies, and blank forms is located at Ogden, Utah, and this office furnishes all the Forests in all the districts with most of the equipment necessary. The record of the property of the United States in the custody of the Forest Service is kept by a man called the Property Auditor. Requisitions for supplies and equipment are made by the Forest Supervisor to the Property Clerk. Government property is considered expendable or non-expendable depending upon its character. Each Forest has a Property Custodian who has charge of all the property assigned to the Forest. When property is received from the Property Clerk or if property is transferred from one forest officer to another, the Property Custodian must note the change on his records.

Blank Forms. The blank forms which are supplied by the Property Clerk are printed standard forms used in issuing permits, making contracts, reports, examinations, timber sale agreements, in short, those used in almost every business transaction of the Forest Service. Even timber estimates, tree measurements, and other similar public records are kept on standard printed forms for permanent uniform record.

Supplies. Supplies such as stationery, typewriters, pencils, ink, notebooks, paper for map work, compasses, measuring tapes, and a host of other articles are furnished upon requisition by the Property Clerk. Equipment such as filing cases, tables, chairs, typewriters, tree-measuring instruments, tents, cooking utensils, surveying instruments, snow shoes, skiis, knapsacks, water buckets, canteens, kodaks, and many other forms of equipment are furnished by the Property Clerk, although in cases of emergency some of these things may be purchased locally by Forest officers by the authority of the Forest Supervisor.

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.

Very often navigable streams and lakes are used as a part of the transportation system on a National Forest. On the Tahoe National Forest in California launches are operated by the Forest Service on Lake Tahoe to patrol the region around the lake for forest fires. Ferries, boats, and launches belonging to private companies or individuals are used by agreement or if necessary are bought by the Service from the Improvement funds. Speeders, motor cars, and hand cars on railroads or logging roads are often used when an agreement has been made with the company. In this way railroads are made a part of the transportation system of the Forest.

Communication Facilities. The system of communication on the National Forests is scarcely less important than the system of transportation. This system includes telephone lines, signal systems, and mail service. The telephone system, as can be readily seen, is of the utmost importance for the transaction of all kinds of National Forest business. In case a Forest Ranger wishes to speak to his Supervisor about controlling a large fire, it makes a great difference whether he can talk to him over the telephone or whether he must send a messenger on horseback perhaps 60 or 70 miles. In the former case practically no time is lost, in the latter it would take at least two days for the messenger to reach the Forest Ranger, and in the meantime the fire would continue to rage and spread.

In the absence of a telephone system a signal system is used. The one probably used the most in forest fire protection work is the heliograph, by which code messages are sent from one point to another by means of a series of light flashes on a mirror. The light of the sun is used and the flashes are made by the opening and closing of a shutter in front of the mirror. Very often these heliograph stations are located on mountain tops in the midst of extremely inaccessible country. Where there are a number of these stations at least one is connected by telephone to the Forest Supervisor's office. When the Forest officer at the telephone gets a heliograph message about a certain fire he immediately telephones the news directly to the Forest Ranger in whose district the fire is located, or if he does not happen to be in direct communication with the Forest Ranger he notifies the Forest Supervisor, who then notifies the officer concerned. Of course it is all prearranged who should be notified in case a fire is reported to the heliograph man.

Unfortunately it has been found that this system of communication is not satisfactory even under favorable conditions. This system depends upon direct sunlight; without it is useless. When there is much smoke in the air it is also of uncertain value. The heliograph system has perhaps reached its greatest development upon the California National Forest, but even here experience has shown that it is only a temporary makeshift and the plan is to replace it by a telephone system as soon as possible.

The Forest Supervisor, especially in his summer headquarters, depends directly upon the mail service for communication with the District Forester and the outside world. In many cases the fact that the Forest Supervisor has his headquarters in a small mountain community in the summer has made it possible for that community to receive a daily mail service or mail at least three times a week. When the Forest Supervisor becomes satisfied that mail service is desirable in certain mountain communities he investigates local settlers' needs for mail facilities; or he may coöperate with the people in the nearest village who are petitioning for mail service. Often his influence proves the deciding factor in getting it.

As I have said before, telephone communication is indispensable to fire protection and to quick and efficient methods of conducting National Forest business. Not only do Forest Service lines enter into the National Forest telephone system but all private lines are also made use of. By coöperative agreements with private companies the National Forest lines are used by private companies, in return for which private lines are used by the Forest Service. In this way a complete network of telephone lines is established connecting not only the Forest Supervisor with all his Rangers and his forest fire lookout stations, but also connecting each one of these with local communities and the large towns at a distance. Thus, when a forest fire occurs and the available local help is not sufficient to control the fire the telephone system is put to use to call help from the nearest villages and towns.

Grazing Improvements. It is often necessary for the complete and economical use of the forage on a National Forest to coöperate with the local stockmen to develop range by constructing improvements. Water may have to be developed; fences, corrals, bridges, trails, and other works may have to be constructed. Often cattle belonging to different stockmen are grazed on adjacent areas which are not separated by natural boundaries such as rivers, ridges, or swamps. If there is no obstacle to prevent the cattle from drifting from one range into another, a drift fence is built, thus definitely separating one stockman's range from the other. Often good range would remain unused on account of lack of water altogether or on account of lack of water during the dry season only. In this case the Forest Service usually coöperates with the stockmen to provide water. Roads, trails, and bridges are often necessary to enable sheep and cattle to reach range lands.

Protective Improvements. Ranger stations, cabins, lookout stations, firebreaks and similar works are required to protect the forests from fire and are known as protective improvements. Buildings are constructed for the field force to afford necessary shelter and to furnish an office for the efficient transaction of business. Land is often cultivated for the production of forage crops and fences are built to insure necessary pasturage for live stock used by the Forest officers in their work. The buildings may be substantial houses to be used throughout the year or they may be merely such structures as will afford the necessary shelter and domestic conveniences for Forest officers in the summer. These summer camps are constructed where needed for the use of patrolmen, officers engaged in timber sale work or at such points as will serve the needs of officers traveling through the forest. Barns, sheds, and other small structures are constructed at the Ranger's headquarters when they are needed. Office buildings are also constructed for the use of Forest Rangers or for summer headquarters of the Forest Supervisor.

Appropriations for Improvement Work. The money for the construction of National Forest improvements is secured from various sources. The annual Forest Service appropriation usually carries a considerable sum for this purpose. In the fiscal year 1918 $450,000 has been appropriated for this work, which divided among the 147 National Forests gives an average only of about $3,000 per Forest. This is really a very small sum considering the size of the average National Forest. Fortunately there are other appropriations and funds and each year sees more money available for this most important work. Under the law 25 per cent. of the receipts are paid to the States in which the National Forests are located to be expended for roads and schools. The amount to be paid to the States in this way from the receipts in 1917 is about $848,874.00. By the acts of Congress organizing them as States, Arizona and New Mexico also receive for their schools funds an additional share of the receipts based on the proportion that their school lands within the National Forests bear to the total National Forest area in the States. The approximate amounts due on account of the receipts for 1917 are $42,844.80 to Arizona and $18,687.56 to New Mexico. Congress has also provided that 10 per cent, of the receipts shall be set aside as an appropriation to be used under the direction of the Secretary of Agriculture for road and trail building in National Forests in coöperation with state authorities or otherwise. The amount thus appropriated on account of the fiscal year 1917 receipts is $339,549.61. This added to the amount carried over from the 1916 receipts fund, $136,981.23, and the amount appropriated for improvements, in the regular Agricultural Appropriation Bill, $450,000.00, brings the total available for the construction of roads, trails, cabins, bridges, telephone lines, etc., on the National Forests for the fiscal year 1918 to $926,530.84.

There is still another fund recently appropriated which will enable roads and trails to be built on a very much larger scale than hitherto has been possible and will result in the rapid opening of forest regions at present practically inaccessible. The Federal Aid Road Act, passed by Congress in 1916, appropriated ten million dollars for the construction and maintenance of roads and trails within or partly within National Forests. This money becomes available at the rate of a million dollars a year until 1927. In general, the States and counties are required to furnish coöperation in an amount at least equal to 50 per cent. of the estimated cost of the surveys and construction of projects approved by the Secretary of Agriculture. The apportionment among the States is based on the area of National Forest lands in each State and the estimated value of the timber and forage resources which the Forests contain.

The total amount from all sources available for roads, trails, and other improvements on the National Forests during the fiscal year 1918 is therefore $1,926,530.84.

THE CLASSIFICATION AND CONSOLIDATION OF NATIONAL FOREST LANDS

The classification and consolidation of National Forest lands is a matter of great importance to their proper administration and protection. If all the lands within the Forests are to be put to their highest use for the permanent good of the whole people the lands inside of their boundaries must be classified and permanent boundaries established for each Forest. Through this kind of work the National Forests gain in stability. The classification and segregation of the agricultural lands is most important, for these lands are open to entry under the Forest Homestead Act.

Land Classification. The land classification work is organized in the Washington and District Offices under the Branch of Lands. Crews of men are sent out from the District Offices and the work of classification, carefully planned ahead, is done by projects, that is, large contiguous areas are examined together. For instance, the Hat Creek Project on the Lassen National Forest consisted of a number of large areas containing scattered parcels of agricultural lands along the Hat Creek valley in that Forest. For the classification of the lands on a big project a surveyor and a lineman, one or more timber cruisers, and an expert from the Bureau of Soils constitute the crew. As a result of this work over 1,100 individual tracts within the Forests were made available for entry under the Forest Homestead Act during the fiscal year 1916, because this land was found to have a greater value for growing agricultural crops than for growing timber. Under this same policy since 1912 about 12,000,000 acres were eliminated from the Forests, partly because they were of greater value for agricultural use, or because they were not suited for the purposes for which the National Forests were created. Up to June 30, 1917, 127,156,610 acres of National Forest land have been examined and classified. Such work as this, once and for all time, will settle the controversy now and then waged in Congress by certain Congressmen that the National Forests have large and valuable tracts of agricultural lands locked up within their boundaries and therefore should be abolished, or turned over to the States, or equally radical disposition made of them. Such Congressmen usually are working for some predatory private interests who want to secure the great wealth in the National Forests that is being wisely conserved for the people.

The Consolidation of National Forest Lands. There has also been a great need for consolidating the National Forest lands where these were interspersed with private or state lands. Congress has recognized this need and from time to time has granted authority to exchange lands with private owners or States where such an exchange would be advantageous to the Government through the resulting consolidation of holdings. Thus by getting the government lands into a more compact body their administration and protection are materially facilitated in many ways.

Before any exchange is made it must be ascertained that the land which the Government is to receive has equal value with that relinquished, also that the land is chiefly valuable for the production of timber and the protection of stream flow. Recent additions to the Whitman National Forest in Oregon consisted of privately owned cut-over timberland rapidly reproducing to valuable timber trees. Title to this will be secured by exchange for government owned lands.

HOW YOUNG FORESTS ARE PLANTED TO REPLACE THOSE DESTROYED BY FIRE

Reforestation and the Timber Supply. More than 15,000,000 acres of National Forest lands which are capable of producing timber and valuable chiefly for that purpose have been denuded of their original tree growth. These lands are not adapted to agriculture and possess but a small value for grazing. In their present condition they are practically unproductive barrens.

It is probable that one-half of this area will reforest itself naturally through the reseeding of burns, and the encroachment of tree growth upon natural openings, parks, grass lands, and brush lands. This natural extension of the forest on such areas is progressing at the estimated rate of 150,000 acres annually. The remaining half of the denuded area, 7,500,000 acres, must be reforested by artificial means. This land is unquestionably adapted to growing timber and useful to the nation primarily for that purpose. Every year that it lies idle the country suffers a great financial loss, for such an immense area is capable of growing at least three-quarters of a billion feet of timber annually. It was recently estimated that the timberlands on the National Forests are producing between five and six billion feet of lumber annually by growth. The complete restocking of the areas now denuded or sparsely timbered will increase the annual production of wood at least 25 per cent., an item certainly worth considering.

Reforestation and Water Supply. Even more important than the value of the timber which is lost annually is the part which these large areas play in the conservation of water supply. Most of this area is on the watersheds of western streams and rivers and the fact that it is denuded is a dangerous menace to the equable flow of the rivers which drain those areas. The National Forests contain over 1,175 watersheds which supply many municipalities, 324 water-power projects, and 1,266 irrigation projects, aside from many other outside power and irrigation projects which are fed by watersheds within the Forests. The cities of Salt Lake City, Utah; Denver and Colorado Springs, Colorado; Portland, Oregon, and Seattle, Washington, all derive their municipal water supply from streams arising in the National Forests. The proposed water system for the city of San Francisco, California, is also to be taken from the National Forest streams. A few years ago planting was undertaken on the watershed of the Colorado Springs, Colorado, reservoir. This water supply is worth annually from $80,000 to $100,000. Besides this the 2,000 horsepower hydro-electric plants are valued at $40,000 and the 40,000 undeveloped horsepower are said to have an additional value of $400,000, making the total value of the watershed more than $500,000, with the probability that a greater water supply having a far greater value will be needed as the city grows.

And there are many evidences that the people of the West have begun to realize that the National Forests are the key to the entire water-supply situation in the West no matter for what purpose the water is used. The public consideration now being given to flood control, the requests from many western cities for special measures to protect their municipal water supply, the concern expressed by irrigation associations in Colorado and elsewhere, lest even the regulated cutting on the National Forests may reduce stream flow, and the rapid rate at which unused reservoir and power sites in the Forests are being developed, all are evidences of the importance of Forests in protecting water supplies. Reforestation is essential so that the National Forests can effectively discharge this function.

Government Reforestation Policy. The duty of the Forest Service to put the denuded areas which will not be reforested naturally into a condition of productivity admits of no further argument. But the problem is not so easily solved as it is made clear. Under the semi-arid conditions prevailing on many National Forests this work involves uncertainties and unsolved problems. On the National Forests artificial reforestation was an untried field when the Forest Service entered it. The Government therefore had to develop its own practice in the face of a great variety of conditions, largely unfavorable. The situation still calls for intensive experiments to develop the best methods from the standpoint of both cost and results. More than that, it calls for a different set of methods for each forest region of the West which has its peculiar trees, climate, and soils. Then, lastly, when the proper methods have been demonstrated by experiment, the new methods can be applied on a large scale with a very good chance for success.

Therefore intensive experiments must come first. Business prudence requires the development of all methods in detail and reasonable certainty as to their results before large sums are expended upon field operations. In the least favorable regions like the semi-arid mesas of the Southwest, the work is restricted for the present to small, carefully conducted experiments, the result sought being reliable information upon how to proceed rather than the reforestation of many acres. In the most favorable regions, as the western slopes of the Rocky Mountains and the Cascade Ranges, the results already obtained have been so excellent, due to an unusual combination of good growing conditions, that operations upon a larger scale have been justified simultaneously with continued intensive investigations. As the work is extended into each new region or new National Forest, the most favorable sites are always chosen first. After the possibilities and limitations of each method have been ascertained by experience under the best conditions of each locality the work can either be intelligently extended or restricted. But the work is always conducted from the standpoint of the maximum return for each dollar expended.

In accordance with the policy outlined by the Forest Service watersheds used for municipal supply or irrigation continue to receive first consideration. Large sums are not, however, being spent on such watersheds where any uncertainty as to the outcome exists; that is before successful methods have been perfected by experiment. In addition to watersheds, reforestation work is being conducted for the primary object of producing timber only where climatic conditions and other factors are extremely favorable. As far as possible these areas are being selected with reference to the low cost of the work, natural conditions which insure rapid tree growth, and urgent local need for additional timber supplies. These favorable conditions generally obtain in Washington, Oregon, Idaho, Montana, Minnesota, and Michigan and it is in these States that the best results have been obtained. In California, Utah, Nevada, Colorado, and the Southwest the work is restricted to intensive experiments on a small scale, until successful methods of meeting the adverse local conditions have been perfected.

Methods of Reforestation. Two general methods of reforestation have been developed. The first is called the direct seeding method, in which tree seed is sown upon the ground with or without simple forms of cultivation. The other method is the planting method by which seedlings are grown in nurseries under ideal conditions of soil, light, and moisture until they are large enough to be transplanted and stand the rigors of the open field. Direct seeding, where successful, is the cheaper method, but is necessarily limited to sites whose soil and moisture conditions are exceptionally favorable to tree growth. The inability of the newly germinated seedling to establish itself except in comparatively moist soil makes the success of this method on the semi-arid mesas of the Southwest, for example, very problematical, especially since these localities are subject to long dry seasons. In such localities the use of the direct seeding method must be restricted to experiments designed to determine the exact range of conditions under which it is feasible. The main effort, however, of the Forest Service has been given to direct seeding on areas where reasonable success appears to be assured. The planting of 2 or 3 year old seedlings or transplants largely overcomes the adverse soil and moisture factors which appear to have made direct seeding unsuccessful in many localities. This method, which is the general practice in European forestry, must without doubt be employed to reforest a considerable portion of the denuded lands. The growing and planting of nursery stock is carried on simultaneously with direct seeding. The object of this is to ascertain the comparative results of the two methods, the sites on which the greater success will be obtained from each, and the proper relation of the two methods in the future development of reforestation work.

Since reforestation work was begun on the National Forests about 135,500 acres have been sowed or planted. The larger part of this acreage was reforested by direct seeding. Until only a few years ago larger areas were direct seeded each year than were planted to nursery stock, but at the present time more planting is being done. During the fiscal year 1916 about 7,600 acres were planted and about 2,800 acres were seeded. The average cost in that year of planting was about $10.00 per acre, that of the seeding was about $4.50 per acre. The 1917 costs were slightly higher, due to the increased cost of labor and supplies.

The reforesting methods of the Forest Service mean the collection of large quantities of seeds and the growing of large quantities of small trees for planting. Since 1911 the Forest Service has collected over 175,000 pounds of seeds for its direct seeding and planting work. During the fiscal year 1916 the Forest Service had 14 large tree-nurseries and 7 small ones, which had in them over 37 million young trees which would, in a short time, be planted in the field. From these figures it is readily seen that the reforestation work on the National Forests is conducted on a large scale.

Direct Seeding Work on the National Forests. The direct seeding work on the National Forests involves many more problems than one would at first thought suppose. Seed must be collected and extracted; it must be stored, if it is not used immediately; if the seed is sown it must be protected from rodents and very often the ground must be prepared before the seed is sown.

Seeds are collected in various ways. Often cones are purchased at advertised rates from persons who make a business of seed collecting. The collectors deliver the cones to a specified Ranger station or to some seed extracting plant. But such collectors are not always available. Seed is collected by Forest officers by stripping cones directly from standing trees or from those felled in logging operations. Large quantities are also gathered from the vast stores or caches assembled by squirrels.

Seed extraction is usually done most economically by experienced Forest officers. It requires drying by exposure to natural or artificial heat to open the cones; threshing to separate the seed from the scales and woody portions of the cone; and cleaning or fanning to remove chaff and dirt. Much of the extraction has hitherto been done in small quantities at a large number of stations and with very simple home-made appliances. In view of the large amount of seed which must be handled each year the cost of extraction has been materially reduced and seed of higher average fertility has been obtained by concentrating the major part of the work at central seed-extracting plants equipped with improved machinery.

A problem of great importance from the standpoint of final results is that of having seed available at the season of the year when it is needed. Past experiments have shown that fall sowing is essential to success in most parts of the West where extensive seeding projects will be conducted. Experience has also shown that seed on a large scale cannot be extracted in time for use in the same season. Moreover, every year is not a good seed year, so that Forest officers must take advantage of the good years to collect large quantities and store them for use during years of seed shortage. Purchased domestic or foreign seed cannot be used to advantage to make up these deficiencies because it is sometimes of poor quality and not adapted to the climatic conditions in which it must be sown. For these reasons methods had to be devised for storing large quantities of seeds for several years at a time and in such a manner that their vitality would not be impaired. Many storage tests have been made by the Forest Service to determine the best way of storing seeds. The tests showed that the sealed glass jar is the best container and that seed must be stored either in air-tight receptacles or at low temperatures to be kept for any considerable period without loss of fertility.

Probably the greatest obstacle encountered in reforestation by direct seeding is the destruction of the seeds by rodents. The failure of many direct seeding projects has been due primarily to loss from this cause. Failure has occurred on areas of practically every character regardless of the time of the year the seed was sown. Success has been encountered only where recent burns had largely eliminated the animals either by outright destruction or by the loss of food supply. The rodents which are most destructive to tree seeds are the ground squirrels, the chipmunks, the mice, and the gophers. It is not strange that they should seek out the seed that has been carefully sown by the Forest officers. In many cases these seeds are their natural food and they are wonderfully diligent and expert in searching it out.

In coöperation with the Biological Survey, the Forest Service has worked on the problem of destroying the rodents. Many methods have been tried out in the field. The free use of grain poisoned with strychnine has thus far produced the best results and has reduced the loss from rodents sufficiently to secure satisfactory germination. The successful elimination of such injury appears to lie in the thorough poisoning by this method of areas to be seeded, once or oftener in advance of sowing.

With successful germination assured by the collection of good seed and the protection of it after it has been sowed from rodents, the next problem lies in cheap methods of cultivation and sowing. This will enable the young seedling to develop its root system early enough and rapidly enough to withstand the first annual drought, the dominant feature of the climate of all the western National Forests.

There are numerous methods used in sowing tree seed on the National Forests. Three general methods are used in most of the work. Broadcast sowing is practiced in the fall and spring or upon the snow in the winter, both on ground that has not been prepared and on soil that has been scarified by rough brush drags, harrowing, disking, or partial or complete plowing. In seed-spot sowing the seed is planted at regular intervals in small spots where the soil is cleared of vegetation and worked up loose to a depth of from 5 to 6 inches. When corn planting or dibbling is practiced the seed is thrust into the soil by a hand corn-planter, or, in the case of large nuts, pressed into holes made with a pointed stick. The corn-planter method is often combined with the preparation of seed spots or the plowing of single furrows, in order to plant the seed in loose soil free from vegetation.

On a large majority of the Forests broadcast seeding on unprepared ground has not succeeded. As a rule satisfactory stands have been secured from broadcasting only after an expensive preliminary cultivation which would be impracticable in extended operations and which would exceed the cost of planting with nursery stock. But broadcasting on prepared strips and upon recent burns has given some success. The seed-spot method has been most successful if done at the proper season. Late summer and early fall sowing has produced better results than sowing in spring or winter. As a whole direct seeding has not succeeded, especially when the results and costs of the work are compared with the planting of nursery stock. Planting has thus far yielded better results, especially on the less favorable areas. Furthermore, from the standpoint of final results attained, planting has actually been cheaper than seeding, in spite of the greater initial cost of planting. While the major emphasis in reforestation work is placed upon planting, considerable seeding is being done, but it is confined to the most favorable localities and sites.

Planting on the National Forests. Reforestation by planting young trees has received much attention during the last few years principally because it has produced better results. Much still remains to be said for both methods and future experiments alone can decide which method to use in a specified region and under given conditions of climate and soil. Usually direct seeding has been tried first in any given locality where reforestation work was to be done. In fact the policy of the Forest Service in artificial reforestation on the National Forests has been, first, to conduct experiments to find out what can be done and what is the best way to do it; second, to reforest by direct seeding wherever this is feasible; and third, to plant nursery seedlings where direct seeding has been found too uncertain.

In selecting areas for planting, preference is usually given to the watersheds of streams important for irrigation and municipal water supply and to land which is capable of producing heavy stands of a quick-growing species or of a specially valuable species. Next in importance are areas which offer good opportunities for object lessons to the public in the practice of forestry. Some areas offer combinations of advantages. For instance, a burned-over tract may be suitable for planting to some rapid-growing species which is also valuable for timber and at the same time may be situated so that it will serve as an object lesson also. It is on such areas in general that reforestation by planting is being concentrated.

While the reforestation of the watersheds of streams important for irrigation and municipal water supply has a large financial value, this value is hard to estimate because it involves not actual cash profit but loss prevented. But when a favorable site is planted to a quick-growing, valuable, species, it is comparatively easy to arrive at a fair estimate of the possible profit on money invested. It has been estimated that under many conditions it is highly profitable to reforest waste lands on the National Forests by planting. From certain experiments made it is estimated that a white pine forest artificially established on a second-class forest soil in Minnesota, will yield about 46,500 board feet per acre in 50 years, worth at least $10 per thousand feet, or $465 per acre. Figuring the cost of planting and the cost of care and protection per acre per year at 3 per cent. compound interest gives a total cost of $34.07 per acre at the time the timber is cut and a net profit of $8.62 per acre per year. Douglas fir in the Northwest will produce 81,000 board feet in 80 years, worth at least $8.50 per thousand feet. After deducting all expenses this would leave a net profit of $555.30 in 80 years or about $6.94 per acre per year. These profits are indeed large, considering that the land is not capable of producing cereal or vegetable crops profitably. And it must be remembered that in all the above calculations all the money invested is earning 3 per cent. compound interest and that the net profits are the earnings in excess of this 3 per cent. interest.

The little trees that are set out on the National Forests every year are produced in large nurseries, where they are grown by the millions. In these nurseries the little trees receive the most expert care from the time the seeds germinate until the time they are large enough to withstand the rigors of wind and weather on the barren hillsides of Uncle Sam's Forests. The seeds are first carefully sown in seed beds and left to develop in these from one to three years. At the end of one year they may be transplanted in nursery rows where they will have more room to develop. Rapidly growing species like yellow pine are kept only a year in the seed bed and perhaps one or two years in the transplant beds; but slow growing species, like cedar, must remain in the seed beds two years and usually two years in the transplant beds. All this depends upon the species and the site upon which it is to be planted.

If my reader were to visit the Pikes Peak region during spring or fall he would doubtless encounter large gangs of men planting young trees on the barren mountain slopes. Under the proper supervision of Forest officers some of the men will be seen digging holes with a mattock while others are coming directly behind them with bags or boxes with wet moss or burlap, containing small trees. These men are called respectively the diggers and planters. Two men will plant from 500 to 1,000 trees a day, depending upon how deep the holes must be dug to accommodate the roots, whether the ground is bare or covered with sod, whether the land is mountainous or level, and many other factors.

In this way Uncle Sam plants his denuded areas in the Forests, so that they will be producing timber for future generations instead of useless brush or tree weeds. The great variety of climatic and topographic conditions included in the National Forest area makes the problem of tree planting infinitely complex. Nursery stock must be raised in each region having similar climatic conditions, and in each of these regions different methods of planting must be used, depending upon local conditions. The semi-arid mesas of Arizona and New Mexico present different planting problems from the humid forest regions of Oregon and Washington; the methods used in the sandhills of Nebraska and the sand plains of Michigan cannot be applied in full on the high mountain slopes of Colorado; nor are the planting problems in the vast chaparral areas of northern California anything like those encountered in the mountains of Idaho, or in the prairie States of the Middle West, or in the Black Hills. Then, again, the reforestation problems of the chaparral fields of southern California are more perplexing than any I have mentioned above.

THE ORGANIZATION AND SCOPE OF FOREST EXPERIMENTS AND INVESTIGATIONS

The Need of Scientific Experiments. No science can make progress without intensive experiments and investigations, least of all a new science like forestry. The science of forestry as it has developed in Europe is several hundred years old, but the science of forestry as applied to American conditions is still in the infancy of its development--probably not over 20 years old. Therefore we know very little about our trees, our forests, and the wood which they produce, and the professional foresters who handle the scientific work on our National Forests are very much handicapped. To supply the needed information about the requirements of many of our tree species, the uses to which their wood can be put, and many other related subjects, the Forest Service has established 8 Forest Experiment Stations (recently reduced to 6) and one Forest Products Laboratory. It has become the business of these institutions to study the laws governing the life of the tree and the forest and their effect upon the final product--wood. The Experiment Stations are working on the solution of the many problems which confront the Forest officers in the management and the protection of the National Forests; while the Forest Products Laboratory was organized to promote the most profitable utilization and the most economical disposition of the forest products of the National Forests. Both sets of institutions, in doing this, are helping materially to build up the science of American Forestry, which even to-day can hardly be said to exist.

The Science of Growing Timber. In order to better understand the many diversified problems which are being studied at the Forest Experiment Stations, it is necessary to give the reader a few ideas concerning the science of forest ecology. This science is the basis of all problems dealing with the growing of timber and is therefore a study of the utmost importance to forestry. Forest ecology is the study of the relations of trees and forests to their surroundings. By surroundings (or environment) we mean all the factors which influence their growth and reproduction, such as soil temperature, soil moisture, soil texture, rainfall, light, wind, air temperature, relative humidity, altitude, slope, exposure, and surface. Forests, we must remember, are not warehouses of standing logs; they are not merely aggregations of individual trees; but they are complex communities of living organisms, which are affected in many ways by climate and soil and which, in turn, affect in no small degree the climatic and soil conditions in their immediate vicinity. The forester cannot treat the forest as an aggregation of individuals, for forests have laws which govern their behavior which are entirely different from those that govern the individual tree. Some foresters and botanists prefer to call this science by the name of "tree sociology," and they compare it with human sociology. Individuals, as we well know, are governed by different natural laws than communities. Just so with trees and forests. In order, therefore, to grow a never-failing supply of timber intelligently and economically we must understand these complex organisms and communities, we must study their behavior under different soil and climatic conditions and ascertain the conditions under which they grow best. Only by doing this can the forester achieve all the objects of forestry, namely, to help Nature to produce more and better timber, in a shorter length of time and at the smallest possible cost.

The experimental work of the Forest Experiment Stations is grouped under such categories as these: dendrological studies, forestation studies, studies in forest influences, studies relating to forest management, studies in forest protection, commercial tree studies, and grazing studies.

Dendrological Studies. Dendrological studies include studies in tree distribution and wood identification. For each tree species growing in the United States (and there are about 500 of them) it is desirable to know its geographical distribution, its commercial distribution, and its local distribution. The first of these deals with the entire range of the tree by geographical divisions; the second of these with the distribution of those bodies of timber that are of commercial quantity or size; and the last deals with the distribution of the tree by local divisions, such as lowlands, slopes, ridges, valleys, plateaus, etc. This information is usually placed on maps for permanent record. Observations by Forest officers on the many National Forests are recorded by them and at the first opportunity sent to Washington. Very often it happens that the range of a species of tree is considerably extended and that a tree is found growing in a locality where it was never reported from before. The identification of woods is done at the Forest Products Laboratory. The distinguishing characteristics of the woods of many American tree species have been determined. The wood of different trees is studied under the microscope to discover in what way it differs from other woods closely related. Many such results are published for the benefit of both the lumber dealer and the general public in the form of bulletins. Both the subject of dyewoods and that of the many woods now sold as mahogany have been investigated in this way. The resulting data have been used by many companies and have helped to protect the public from frauds.

Seed Studies. Experiments in reforestation are grouped under seed studies, nursery studies, and sowing and planting. Considerable work has been done in developing the best methods of seed-extraction. Much valuable information has been gathered on the largest amount of seed that may be extracted from pine cones of different species per unit of time at different degrees of temperature; the maximum temperature which may be applied to seeds of different species without impairing their vitality; the germinating power of seed extracted at different temperatures; the comparative length of time required for the germination of seed extracted with or without artificial heat; and the most economical type of seed-extracting plant. Studies have been made upon the comparative germination of tree seeds in the field and the greenhouse. The ultimate success of the plantations being established on the National Forests in a large degree depends upon the character of the seed used. Hence studies are being conducted of the effect of altitude, soil, age of the tree, density of stand, insect damage and disease infection, and other factors that affect the mother tree, upon the character of the seed collected from those trees, and the growth and form of the resulting seedling. Also tests to show the effect of the source of seed on the form and growth of young seedlings have indicated very clearly that with all species the seed grown in the locality where the trees are to be planted give as a rule better results than seed imported from another region.

Nursery Studies. Nursery studies endeavor to show the most efficient methods for growing young trees for field planting for each species of trees. It is of great importance to know how much seed to sow per foot in the nursery beds; what is the best time (spring or fall) for sowing; to what depth the seed should be covered in order to give the highest germination; whether better results are obtained by drill sowing or by broadcast sowing; the best methods of shading, fertilizing, watering, and cultivating the seed beds; the methods of securing the best root development of the young seedlings; the best time and method of transplanting from the nursery beds to the transplant beds; the best methods for retarding spring growth in seedlings to be used at high altitudes; and other problems of similar nature.

Forestation Experiments. Experiments in forestation have, year after year, proven that planting is much safer than direct seeding and ultimately less expensive. For this reason a greater emphasis has been placed upon planting studies. These studies have attempted to show the best season for planting each species; the best methods of planting; the most advantageous classes of stock to use; and what the most suitable sites are for each species of tree.

Studies of Forest Influences. Studies on the influence of forests upon stream flow and erosion are attempting to furnish important data for American conditions upon this subject. At the Wagon Wheel Gap Forest Experiment Station in Colorado such a study is being carried on. The purpose of the study for the first two or three years has been to determine the character of the two streams which are to be measured. The forest cover on the two watersheds is practically identical. The results so far obtained indicate that the influence upon the stream flow must be about the same in both cases, and, consequently, a comparison of these streams after the denudation of one watershed will be a very fair test of the influence of the forest cover upon the relative height of the flood stage and low-water stage, the amount of erosion, and the rate of melting of the snow.

Experimental observations which have been conducted since 1908 at the various Forest Experiment Stations have shown that the forest exercises a decided moderating influence upon temperature extremes, wind motion, and evaporation. Likewise, the presence of a forest cover retards the melting of snow in the spring, and in this way huge snowbanks in the forests feed the nearby streams until late in the summer. Forests therefore have been shown to conserve the water supply and also causing this water to run off slowly rather than in sudden floods. Studies have also been conducted on determining the effect of cutting timber upon the climate within the forest.

Meteorological Observations. The climatic requirements of forest types have been studied at the Fremont Experiment Station since January 1, 1910, through experimental observations, and other stations have taken up the same problem since that date. The first step in this work at the Fremont has been to obtain a complete meteorological record as a basis for determining what climatic conditions are most important in limiting the natural range of such important species as Yellow pine, Douglas fir, and Engelmann spruce. The data collected so far have shown that soil moisture and soil temperature are the controlling factors in determining the existence of the three forest types. It has also been shown what climatic conditions each of the three types of forest must have in order to succeed. This work has since been extended to include other types of forest and a meteorological station has been established at timber line on Pikes Peak. This station, which is at approximately 11,500 feet, is equipped with self-recording instruments to measure the climatic factors which obtain at that elevation and which mark the uppermost altitudinal limit of tree growth in that locality.

Such studies as these, based upon systematic meteorological observations, have an important bearing on all other forest problems. The data secured in this way especially assist the technical foresters in solving the various problems in forest management, reforestation, fire protection, and land classification, besides giving positive knowledge of the environment in which our trees live and of the factors affecting their growth and reproduction. These systematic observations are of prime importance if we ever hope to have a science of American Forestry.

Forest Management Studies. Experiments in forest management are carried on to determine the best methods of cutting National Forest timber to secure natural reproduction and at the same time to improve the quality and productivity of the remaining stand. These studies are carried on by means of permanent sample plots, on which all the trees are carefully measured and recorded. First the timber is cut on the plots under different systems of management, or thinnings or improvement cuttings are made. An exact record is kept of the amount of timber removed and of the size and distribution of the remaining trees. Measurements taken at regular intervals show the precise effect of the method used on each plot. Close observations of the reproduction which takes place, brush and other forms of cover which may establish themselves, and changes in soil conditions are recorded. On similar sample plots methods of brush disposal, methods of marking timber for cutting, and thinning methods are studied. After logging there are several ways in which the resulting slash may be disposed, depending upon surrounding conditions. In some localities the brush must be burned immediately on account of the fire danger which its presence involves; in other places it must be removed because it interferes with reproduction; in still other places the brush may be scattered over the area because there is little fire danger and, in fact, the brush has been found to assist and protect reproduction. All these possibilities must be determined by experiments. Likewise in marking timber for cutting and in thinning practice various methods are possible, depending upon circumstances, the most important of which are the requirements of the species and the density of the forest.

Other management studies deal with the determination by actual measurement of the volumes of trees and stands, and the growth of trees and the yields of whole forests. Reliable growth and yield data for the different species and types are necessary to properly handle timber sales as well as for forest management. They are also essential for determining damages caused by fires and trespass.

Forest Protection Studies. Studies in forest protection endeavor to find the best methods of protecting the National Forests from fire, grazing, disease, insects, wind, snow, hail, and animals. The most efficient protection of the National Forests from fire calls for an accurate, scientific knowledge of all the factors that enter into the problem. Comprehensive studies are undertaken to secure the basis for a more scientific method of distributing National Forest fire-protecting funds. The aim has been to find the degree of intensiveness in fire protection warranted by timber, forage, and watershed values, as modified by their susceptibility to damage by fire. Under the ideal system of allotting fire-protecting funds, the most valuable resources, which at the same time are most in danger of destruction by fire, should receive the largest amount of funds and therefore the greatest amount of protection. Less valuable resources, less susceptible to fire danger, should receive protection in proportion. Other classes of fire protection studies have to do with the various phases of fire prevention, fire detection, and fire control. Studies have also been carried on to determine the rapidity with which fire spreads in different forest types, and under a given set of climatic conditions.

Protection from Grazing Damage. Studies of the effects of grazing upon the natural reproduction of forests are conducted with a view to devising a system of range control which would minimize such injury without requiring the total exclusion of the stock from the range. Studies have shown that serious damage occurs to seedlings under four feet in height during the dry season, on areas containing poor forage, or which have been overgrazed, or where there was little or no underbrush. It was found that sheep do twice as much damage as cattle. Some of the measures that have been adopted to lessen the injury to reproduction by sheep and cattle are: the revegetation of overgrazed areas, reductions in the amount of stock, provisions for the better distribution of stock by the regulation of watering places, and the exclusion of sheep from cut-over areas on which reproduction is deficient until the seedlings reach a sufficient height to be out of the reach of the animals.

Protection from Insects and Diseases. In coöperation with the Bureau of Entomology and the Bureau of Plant Industry the Forest Service is conducting a large number of studies and investigations dealing with the insects and diseases that do destructive damage to forests. The direct result of these studies will be the gradual eradication of predaceous insects and dangerous tree diseases from the valuable timber forests of the Government. Control measures already taken have shown the value of exact scientific information. On the Klamath National Forest some years ago about 900 acres were treated for insect infestation. The cost was about $3,000 and the amount of timber saved by the eradication of the insects was worth over $600,000. Other studies are carried on to identify and describe certain classes of insects, such, for instance, as those that destroy the seeds of trees in the cones. The various families, genera, and species of forest insects are studied and described, and the results are published in the form of monographs. Many of these insects are difficult to identify and concerning others very little is known. Investigations on tree diseases have not made such good progress, because tree diseases are much more difficult to control. Tree diseases, like human diseases, must be prevented instead of controlled. A general survey of the tree diseases prevalent in the National Forests has been made, especially in California. Further studies have brought to light little known or even unknown diseases. In California, studies have shown that a certain relation exists between old age and disease. Incense cedar, for example, seems to become infested after it reaches maturity at an age of about 150 years.

Tree Studies. Commercial tree studies are made of important tree species. The results are published in the form of monographs dealing with the range, silvicultural characteristics, growth, yield and management of each tree. These studies bring together all the important facts known about the tree described, such as: the industrial uses of the wood, the conditions under which the tree succeeds, the rate of growth in different situations, and the most suitable methods of management to secure the highest returns. Tables are included to show the volume of the trees at different ages and sizes, in cubic feet, in cords, in board feet, etc. Studies are also made of the life history and requirements of important forest trees, often in connection with commercial studies. Such studies cover: local, geographical, and commercial occurrence of the species, the species which are associated with it, the habit of the tree, its soil and climatic requirements for germination and growth, and the various matters connected with its reproduction. Such publications as these give the Forest officers much valuable information about the trees with which they are dealing, and also furnish the only sources of information to students in forest schools on the characteristics and requirements of the trees important in forestry in this country.

Grazing Investigations. Grazing investigations, being intimately connected with a great national industry, have received a considerable amount of attention. These studies are confined at present to grazing reconnoissance, the reseeding of depleted mountain grazing lands, studies in the best methods of handling sheep on the range, studies of the effect of grazing on the forest, identification of range plants, and the systematic elimination of poisonous range plants and predatory animals.

Grazing reconnoissance is a stock taking of the forage possibilities of a certain piece of range land. This work is usually done by organized parties, but a small amount is done also by Forest officers in spare time. This study aims to collect all the important grazing information, such as: the area of grazing lands, the kind of forage, the species of forage plants, the location of streams, springs, and other watering places for stock, the location of stock driveways, drift fences, and cabins, the location of timber lands that do and those that do not contain forage, and many other matters pertaining to the grazing of stock. The maps and field data secured furnish the basis for range improvement and more intensive range management. Up to date, over 12,288,885 acres of range lands have been covered in this way.

All intensive forage and range experiments are conducted at the Great Basin Experiment Station on the Manti National Forest. Here intensive problems are carried on under controlled conditions and under constant and careful observation and the necessary care and thoroughness is given to them which could only be given them at a fully equipped experiment station. All grazing investigations on the National Forests are carried on under the direct supervision of this station.

The seeding of depleted grazing lands is accomplished either by direct artificial seeding or through rotation grazing. Under the former method the seed of native or foreign grasses and other range plants are sown on the range, in the attempt to increase the forage crop. By rotation grazing, that is, permitting the stock to feed first on one area and then on another, the grasses and forage plants are allowed to recuperate from the effect of grazing and allowed to reproduce. The stock is excluded from one area while the seed is maturing, and after the seed has matured and become scattered on the area the stock is allowed to graze on it. As the stock feeds on the plants it tramples the seed into the ground and thereby furnishes favorable conditions for the germination of the seed. There are few parts of the National Forests that cannot be completely regenerated by the adoption of either one or the other of these two methods.

To reduce interference with the natural processes of reforestation, damage to tree growth and watersheds, depletion of grazing lands, and the waste of valuable forest resources, it is important to develop improved methods of managing different kinds of live stock on different types of land. These new methods of handling stock have been applied only to sheep. The lambing of sheep in small inclosures on the open range has resulted in the saving of a large percentage of the lambs. The new method of bedding sheep where they happen to be at nightfall has been found to have many advantages over the old system of returning them to an established bedding ground a number of nights in succession. The results have been better sheep, less damage to range, and more feed.

It was not so many years ago that practically nothing was known about the various plants which make up the forage crop on the National Forests. Forest officers could not identify the plants or say whether they were of value for forage or not. This made it difficult to secure the use of each range by the class of stock to which it was best adapted, to apply deferred and rotation grazing and to eliminate losses from poisonous plants. This obstacle to efficient range management was overcome when a system of plant collection and identification was started by the Forest Service. Some 23,000 specimens of about 3,000 different species have been collected on the National Forests, identified by specialists and the collector informed as to the value of each species. The identification of range plants is the first step toward securing an intimate knowledge of the life history of the plant. Such information as the soil and moisture requirements, date of flowering and seeding, requirements for reproduction, and its relation to other range plants is of the utmost importance if the maximum forage crop is to be produced on the range each year. This constitutes the latest stage in the development of grazing studies.

Investigations Dealing with Poisonous Plants and Predatory Animals. In coöperation with the Bureau of Plant Industry the study of poisonous plants and the means for reducing the losses from them has been undertaken. The death camas, the lupines, the larkspurs, some of the wild cherries, locoweed, and practically all species of zygadenus are plants that have been found to cause death among stock. While the handling of stock to avoid the poison areas can eliminate the losses to a small extent, it has been found that the most expeditious remedy is in digging out and destroying the poisonous plants. On the Stanislaus National Forest in California, a cattle range of about 14,000 acres, containing about 67 acres of larkspur, was cleared of this weed at a cost of about $695. The average loss of cattle in previous years had been about 34 head. Following the eradication of the larkspur the loss was 4 head. The net saving was valued at $1,800. Similar operations are conducted on other Forests.

The work of the destruction of predatory animals has been transferred to the hands of the Bureau of Biological Survey. Formerly special Forest Service hunters were detailed to hunt the animals, and these men used to kill about 4,000 a year. The Biological Survey, however, still furnishes traps, ammunition and poison for the destruction of predatory animals to Forest officers, who do this work in connection with their regular duties. Bears, coyotes, mountain lions, lynxes, wildcats, and wolves are the animals that do the most of the damage. What makes the problem a difficult one is that the wolf and the coyote, the two species which do the greatest damage to game and domestic stock, are transient visitors on the Forests which frequent the Forests only when game and stock is most abundant. They are bred, born, and spend the greater portion of their lives in the foothills outside of the National Forests. Under these conditions the animals killed on the Forests are quickly replaced by others from outside. For this reason the matter was handed over to the Biological Survey, which will destroy these animals throughout the public domain and the results will be much more permanent and effective.

Besides the investigations carried on by the Forest Experiment Stations many studies are carried on dealing with forest products. The purpose of the Branch of Forest Research of the Forest Service is to promote the most profitable and economical utilization of forest products by means of experiments and investigations. The work of the Branch falls into three divisions: National Forest utilization, the work of the Forest Products Laboratory, and industrial investigations.

National Forest Utilization Experiments. The work of the proper utilization of the products of the National Forests is under the supervision of the District Forester and the Assistant District Forester in charge of Forest Products in the districts. Only three out of the seven districts have such an organization. These men have charge of all problems connected with the use and marketing of National Forest timber, the construction of improvements on the Forests, and related administrative questions. The following problems are included: studies of existing industries, covering methods and costs of manufacture, grades, and other specifications of manufactured products and the prices obtained for such products; the collection of market prices, mill scale studies to determine grades and overrun, and investigations in kiln drying; waste in existing industries and closer utilization possible through improved methods; new uses for National Forest species through wood preservation; introduction of industries which will result in closer or more profitable utilization, as the manufacture of pulp and paper, wood distillation, turpentining, and the manufacture of secondary wood products; overcoming prejudices against particular species or classes of material; general questions of timber supply and demand, markets and freight rates; advice and assistance in the construction of National Forest improvements, particularly in the use of wood preservatives; advice and assistance to persons on any matter connected with the utilization of National Forest timber; the preparation of publications upon subjects covered by investigations which have practical or scientific value; and demonstrations of methods or processes developed by the Forest Service for the benefit of local communities.

The presence on a Forest of large quantities of unmarketable timber, or dead timber, or of material not used in current sales would mean an investigation of methods for its utilization. Local problems affecting wood-using industries in manufacturing or marketing timber, such as sap stain in lumber, difficulties in seasoning lumber, and the effect of different silvicultural methods upon the average grades of lumber manufactured, are also taken up with the Products experts at the District Office. Also in the construction of National Forest improvements the Forest Supervisor may need assistance in applying wood preservatives to telephone poles, fence posts, and other material. Sometimes timber treating plants are erected, if necessary, to treat not only material used on the National Forests, but also material used by local residents near a Forest.

One of the important problems which confronts the Office of Products in the various National Forest districts is the utilization of the so-called low grade or inferior tree species. The terms "high grade" and "low grade" or "inferior," as used at present, merely indicate the lumberman's valuation of the timber from his point of view and according to his standards of value. If a certain species will not produce clear lumber, which is straight-grained, easily worked, and not subject to splitting or warping, it is at once classed as inferior. But the Forest Products specialists each year are making progress in demonstrating that wood, in order to be of marketable value, does not necessarily need to be cut in the form of lumber. It is also being shown that proper methods of drying lumber make possible the use of inferior woods for lumber and manufacturing purposes.

The Office of Forest Products in California has made considerable progress in overcoming the lumberman's prejudices against the inferior species in the California National Forests and the species are beginning to find wider use and to command better prices. The discovery that Incense cedar was valuable for making lead pencils caused the price of this so-called "inferior" species to jump from an average of $10 per thousand feet in logs f. o. b. cars to as high as $16. White fir, a species religiously avoided by lumbermen in the woods, was found to have special properties which make it very valuable as a pulpwood. One mill in California now uses annually upwards of 30,000 cords of it for making paper. Lodgepole pine has been shown to have a great value for telephone and telegraph poles when treated with preservatives. It was found to be 12 per cent. stronger than Western Red cedar, the standard pole timber, has a more desirable taper and can be shipped for less money. Many other cases could be cited from this and other National Forest Districts.

Forest Products Laboratory Experiments. The work of the Forest Products Laboratory includes investigations on the mechanical properties of wood; the physical and chemical characteristics and properties of wood; air seasoning and artificial drying of wood; agencies destructive to wood; wood preservation; wood distillation; production of naval stores; and the production of pulp and paper and other chemical products of wood. This work is carried on at the Laboratory and sometimes in coöperation with the National Forests and district experts. At the Laboratory there is a director and a large staff of technical and scientific men, such as chemists, physicists, and engineers, each of whom is an expert in his particular line of work.

A good deal of attention is given to testing the strength of woods grown in the United States, as a means of assisting users to select the species best adapted to a given purpose, or to find substitutes for species which are becoming difficult to obtain. The strength of a good many species used for structural timbers has been tested. The species most used for this class of timber are the Southern pines, Douglas fir, Norway pine, Tamarack, and Red spruce. An important discovery was made several years ago that Western hemlock, generally considered an inferior timber, showed an average strength 88 per cent. as great as that of Douglas fir, one of the best construction timbers in the United States. Strength tests have also been made on fire-killed timber and these have shown that timber killed by fire is almost as strong as green timber. Other tests have been made to determine the effect of preservative treatment upon the strength of timber. As a result of the large number and variety of strength tests carried on by this Laboratory the United States Government now has a more thorough and comprehensive collection of data on the mechanical properties of wood than any other nation.

Many studies are also conducted to determine the physical properties and the structure of the different kinds of wood grown in this country. The minute structure of the wood of many of our native species has been studied by means of microscopic slides. A study has also been made of a large number of species to determine the specific gravity of the actual wood substance. Other tests are made to determine the specific heat of woods.

The drying or seasoning of woods, more especially of certain species which have been found difficult to season, has received a good deal of attention. A new type of kiln, invented by a Forest Service man, has been devised to season such woods as the eucalyptus, which has always been very difficult to handle in drying. Western larch has been seasoned with a loss of only 5 per cent., whereas the loss in ordinary commercial kilns usually ran between 60 and 70 per cent. As a result, many manufacturers have remodeled their old kilns to embody the new Forest Service methods. A new method has also been developed for the rapid dry-kilning of Eastern hemlock, which has great commercial possibilities.

Experiments in wood preservation have to do with the kind of preservatives it is best to use, the character of the wood to be treated, and the methods of injection. Experiments have developed the best methods for treating railroad ties, mine timbers, fence posts, wood paving blocks, telephone and telegraph poles, and wharf piling. Untreated mine timbers have been found to last only from 1 to 2 years, while treated ones are usually entirely sound at the end of 4 years. Untreated railroad ties last from 5 to 10 years, while treated ones will last over 15. Such experiments as these have shown the advisability of treating all kinds of timbers with creosote or zinc chloride, or some other preservative. Many new preservatives are being proposed or marketed each year by various companies or individuals. These are all tested to determine their value to prevent the growth of fungi in the wood. Their efficiency varies greatly and many of them have been shown to have very small value.

Studies in wood distillation seek to find new woods which can be used for this industry, new and more efficient methods which can be employed, and new uses for wood waste and stumps. Charcoal, wood alcohol, acetate of lime, and tar are derived from the distillation of such woods as beech, birch, and maple, to which tar oils and turpentine are added for the pines and other resinous woods. These by-products of wood distillation have many uses, as well as the many products which are, in turn, made from these by-products. Charcoal is used in the manufacture of black powder, acetic acid is used in the manufacture of explosives, and wood alcohol is converted into formaldehyde for disinfection against contagious diseases. By means of temperature control methods developed at the Laboratory in the destructive distillation of hardwoods, the net gain per annum of one company's plant was over $17,000. About one-half of the plants of the country have adopted the new method developed by the Forest Products Laboratory.

Experiments have been conducted by the Laboratory in the distillation of the needles of coniferous trees and the distillation of the crude gum of some of the important timber trees of the South and West. The oils distilled from many trees in this way have found great use for various purposes. Shoeblacking owes its peculiar aromatic odor, faintly suggestive of the deep spruce and hemlock woods, to an oil which is distilled from these same kind of needles. Evergreen tree leaf oils are used for the perfume of soap, and in the manufacture of liniments, insecticides, and medicinal preparations.

Investigations have been carried on at the Forest Products Laboratory in making artificial silk from sawdust. The industry has already attained considerable proportions. It consists principally of converting cellulose into viscose, which, in turn, is manufactured into an almost endless number and variety of silk and other goods varying from sausage casings to silk hose and tapestries. Sawdust is used also in the manufacture of inlaid linoleum and dynamite.

Experiments in naval stores are attempting to improve the old methods of harvesting turpentine, which have proven very destructive to the forests. With the approaching exhaustion of the Southern Pinery as a field for the naval stores industry, it has become more and more important to find other species for this purpose. Consequently the Laboratory has conducted experiments with the various pines on the National Forests in California, Colorado, Arizona, and New Mexico.

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 principal supply are circumstances 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 quantities. 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 shipment. 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, substitution 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 assistance 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 shingle, 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 establishing 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 coöperators 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 knobs. A clock maker of Connecticut secured waste material for making clock boxes from the planing mill of a New York lumber company.
