No. 8. Alaska District, Juneau, Alaska.
(Alaska.)
Each of the National Forests is under the direct supervision of a forest supervisor and is split up into from 5 to 10 or more ranger districts. Each ranger district is in charge of a forest ranger who has an area of from 100,000 to 200,000 acres in his charge.
The National Forests are, for the most part, located in the mountainous region of the West, with small scattered areas in the Lake States, and the White Mountains, Southern Appalachians and Ozarks of the Eastern and Southern States. Many of them are a wilderness of dense timber. It is a huge task to protect these forests against the ravages of fire. Fire fighting takes precedence over all other work in the National Forests. Lookout stations are established on high points to watch for signs of fire. Airplanes are used on fire patrol over great areas of forest. Where railroads pa.s.s through the National Forests, rangers operate motor cars and hand-cars over the tracks in their patrol work. Launches are used in Alaska and on some of the forests where there are large lakes, to enable the fire fighters and forest guardians to cover their beats quickly. Every year the National Forests are being improved and made more accessible by the building of permanent roads, trails and telephone lines.
Special trails are built to and in the fire protection areas of remote sections. A network of good roads is constructed in every forest to improve fire fighting activities as well as to afford better means of communication between towns, settlements and farms. The road and trail plan followed in the National Forests is mapped out years in advance. In the more remote sections, trails are first constructed. Later, these trails may be developed into wagon or motor roads. Congress annually appropriates large sums of money for the building of roads in the National Forests. Over 25,000 miles of roads and 35,000 miles of trails have already been constructed in these forests.
Communication throughout the National Forests is had by the use of the telephone and the radio or wireless telephone. Signalling by means of the heliograph is practiced on bright days in regions that have no telephones. Arrangements made with private telephone companies permit the forest officers to use their lines. The efficient communication systems aid in the administration of the forests and speeds the work of gathering fire fighters quickly at the points where smoke is detected.
Agricultural and forestry experts have surveyed the lands in the National Forests. Thus they have prevented the use of lands for forestry purposes which are better adapted for farming. Since 1910, more than 26,500,000 acres of lands have been excluded from the forests. These lands were more useful for farming or grazing than for forestry. Practically all lands within the National Forests have now been examined and cla.s.sified. At intervals Congress has combined several areas of forest lands into single tracts. Government lands outside the National Forests have also been traded for state or private lands within their boundaries.
Thus the forests have been lined-up in more compact bodies.
Careful surveys are made before such trades are closed to make sure that the land given to Uncle Sam is valuable for timber production and the protection of stream flow, and that the Government receives full value for the land that is exchanged.
The National Forests contain nearly five hundred billion board feet of merchantable timber. This is 23 per cent. of the remaining timber in the country. Whenever the trees in the forest reach maturity they are sold and put to use. All green trees to be cut are selected by qualified forest officers and blazed and marked with a "U.S." This marking is done carefully so as to protect the forest and insure a future crop of trees on the area.
Timber is furnished at low rates to local farmers, settlers, and stockmen for use in making improvements. Much fire wood and dead and down timber also is given away. The removal of such material lessens the fire danger in the forest.
Over a billion feet of timber, valued at more than $3,000,000, is sold annually from the National Forests.
One generally does not think of meat, leather and wool as forest crops. Nevertheless, the National Forests play an important part in the western livestock industry. Experts report that over one-fifth of the cattle and one-half of the sheep of the western states are grazed in the National Forests. These livestock are estimated to be worth nearly one-quarter billion dollars. More than 9,500,000 head of livestock are pastured annually under permit in the Federal forests. In addition, some 4,000,000 to 6,000,000 calves and lambs are grazed free of charge.
[Ill.u.s.tration: SEED BEDS IN A FOREST NURSERY]
The ranges suitable for stock grazing are used to pasture sheep, cattle, horses, hogs and goats. The Secretary of Agriculture decides what number and what kind of animals shall graze on each forest. He regulates the grazing and prevents injury to the ranges from being overstocked with too many cattle and sheep. The forest ranges are divided into grazing units. Generally, the cattle and horses are grazed in the valleys and on the lower slopes of the mountain. The sheep and goats are pastured on the high mountain sides and in the gra.s.sy meadows at or above timberline.
Preferences to graze live stock on the forest ranges are for the most part granted to stockmen who own improved ranch property and live in or near one of the National Forests. The fee for grazing on forest ranges is based on a yearlong rate of $1.20 a head of cattle, $1.50 for horses, $.90 for hogs and $.30 a head for sheep.
At times it is necessary, for short periods, to prohibit grazing on the Government forest ranges. For example, when mature timber has been cut from certain areas, it is essential that sheep be kept off such tracts until the young growth has made a good start in natural reforestation. Camping grounds needed for recreation purposes by the public are excluded from the grazing range. If a shortage of the water supply of a neighboring town or city threatens, or if floods or erosion become serious due to fire or overgrazing of the land, the range is closed to live-stock and allowed to recuperate. Where artificial planting is practiced, grazing is often forbidden until the young trees get a good start.
The total receipts which Uncle Sam collects from the 30,000 or more stockmen who graze their cattle and sheep on the National Forests amount to nearly $2,500,000 annually. As a result of the teachings of the Forest Service, the stockmen are now raising better livestock. Improved breeding animals are kept in the herds and flocks. Many of the fat stock now go directly from the range to the market. Formerly, most of the animals had to be fed on corn and grain in some of the Middle Western States to flesh them for market. Experiments have been carried on which have shown the advantages of new feeding and herding methods. The ranchers have banded together in livestock a.s.sociations, which cooperate with the Forest Service in managing the forest ranges.
It costs about $5 to sow one acre of ground to tree seed, and approximately $10 an acre to set out seedling trees. The seed is obtained from the same locality where it is to be planted. In many instances, cones are purchased from settlers who make a business of gathering them. The Federal foresters dry these cones in the sun and thresh out the seed, which they then fan and clean. If it is desired to store supplies of tree seed from year to year it is kept in sacks or jars, in a cool, dry place, protected from rats and mice. Where seed is sown directly on the ground, poison bait must be scattered over the area in order to destroy the gophers, mice and chipmunks which otherwise would eat the seed. Sowing seed broadcast on unprepared land has usually failed unless the soil and weather conditions were just right.
For the most part, setting out nursery seedlings has given better results than direct seeding. Two men can set out between five hundred and one thousand trees a day.
The National Forests contain about one million acres of denuded forest lands. Much of this was cut-over and so severely burned before the creation of the forests that it bears no tree growth.
Some of these lands will reseed themselves naturally while other areas have to be seeded or planted by hand. In this way the lands that will produce profitable trees are fitted to support forest cover. Because the soils and climate of our National Forests are different, special experiments have been carried on in different places to decide the best practices to follow. Two method of reforestation are commonly practiced. In some places, the tree seed is sown directly upon the ground and, thereafter, may or may not be cultivated. This method is limited to the localities where the soil and moisture conditions are favorable for rapid growth.
Under the other plan, the seedlings are grown in nurseries for several years under favorable conditions. They are then moved to the field and set out in permanent plantations.
CHAPTER X
THE NATIONAL FORESTS OF ALASKA
There are two great National Forests in Alaska. They cover 20,579,740 acres or about 5-1/2 per cent. of the total area of Alaska. The larger of these woodlands, the Tonga.s.s National Forest, is estimated to contain 70,000,000,000 board feet of timber ripe for marketing. Stands of 100,000 board feet per acre are not infrequent. This is the Alaskan forest that will some day be s.h.i.+pping large amounts of timber to the States. It has over 12,000 miles of sh.o.r.e line and ninety per cent. of the usable timber is within two miles of tidewater. This makes it easy to log the timber and load the lumber directly from the forests to the steamers. This forest is 1500 miles closer to the mainland markets than is the other Alaskan National Forest.
In most of the National Forests the rangers ride around their beats on horseback. The foresters in the Tonga.s.s use motor boats.
They travel in couples; two men to a 35-foot boat, which is provided with comfortable eating and sleeping quarters. The rangers live on the boat all the time. During the summer they work sixteen to twenty hours daily. The days are long and the nights short, and they must travel long distances between points of work. On such runs one man steers the boat and watches the forested sh.o.r.eline for three or four hours at a time, while his mate reads or sleeps; then they change off. In this way, they are able to make the most efficient use of the long periods of daylight.
The other big timberland in Alaska is the Chugach National Forest. It is a smaller edition of the Tonga.s.s Forest. Its trees are not so large and the stand of timber only about one-half as heavy as in the Tonga.s.s. Experts estimate that it contains 7,000,000,000 board feet of lumber. Western hemlock predominates.
There is also much spruce, poplar and birch. Stands of 40,000 to 50,000 feet of lumber an acre are not unusual. In the future, the lumber of the Chugach National Forest will play an important part in the industrial life of Alaska. Even now, it is used by the fis.h.i.+ng, mining, railroad and agricultural interests. On account of its great distance from the markets of the Pacific Northwest it will be a long time before lumber from this forest will be exported.
The timber in the Tonga.s.s National Forest runs 60 per cent.
western hemlock and 20 per cent. Sitka spruce. The other 20 per cent. consists of western red cedar, yellow cypress, lodge-pole pine, cottonwood and white fir. The yellow cypress is very valuable for cabinet making. All these species except the cedar are suitable for pulp manufacture. Peculiarly enough, considerable of the lumber used in Alaska for box shooks in the canneries and in building work is imported from the United States. The local residents do not think their native timber is as good as that which they import.
Alaska will probably develop into one of the princ.i.p.al paper sources of the United States. Our National Forests in Alaska contain approximately 100,000,000 cords of timber suitable for paper manufacture. Experts report that these forests could produce 2,000,000 cords of pulpwood annually for centuries without depletion. About 6,000,000 tons of pulpwood annually are now required to keep us supplied with enough paper. The Tonga.s.s National Forest could easily supply one-third of this amount indefinitely. This forest is also rich in water power. It would take more than 250,000 horses to produce as much power as that which the streams and rivers of southern Alaska supply.
The western hemlock and Sitka spruce are the best for paper making. The spruce trees are generally sound and of good quality.
The hemlock trees are not so good, being subject to decay at the b.u.t.ts. This often causes fluted trunks. The b.u.t.t logs from such trees usually are inferior. This defect in the hemlock reduces its market value to about one-half that of the spruce for paper making. Some of the paper mills in British Columbia are now using these species of pulpwood and report that they make high-grade paper.
The pulp logs are floated down to the paper mill. In the mill the bark is removed from the logs. Special knives remove all the knots and cut the logs into pieces twelve inches long and six inches thick. These sticks then pa.s.s into a powerful grinding machine which tears them into small chips. The chips are cooked in special steamers until they are soft. The softened chips are beaten to pieces in large vats until they form a pasty pulp. The pulp is spread over an endless belt of woven wire cloth of small mesh. The water runs off and leaves a sheet of wet pulp which then is run between a large number of heated and polished steel cylinders which press and dry the pulp into sheets of paper.
Finally, it is wound into large rolls ready for commercial use.
If a pulp and paper industry is built up in Alaska, it will be of great benefit to that northern country. It will increase the population by creating a demand for more labor. It will aid the farming operations by making a home market for their products. It will improve transportation and develop all kinds of business.
Altogether 420,000,000 feet of lumber have been cut and sold from the national forests of Alaska in the past ten years. This material has been made into such products as piling, saw logs and s.h.i.+ngle bolts. All this lumber has been used in Alaska and none of it has been exported. Much of the timber was cut so that it would fall almost into tide-water. Then the logs were fastened together in rafts and towed to the sawmills. One typical raft of logs contained more than 1,500,000 feet of lumber. It is not unusual for spruce trees in Alaska to attain a diameter of from six to nine feet and to contain 10,000 or 15,000 feet of lumber.
Southeastern Alaska has many deep-water harbors which are open the year round. Practically all the timber in that section is controlled by the Government and is within the Tonga.s.s National Forest. This means that this important crop will be handled properly. No waste of material will occur. Cutting will be permitted only where the good of the forest justifies such work.
CHAPTER XI
PROGRESS IN STATE FORESTRY
The rapid depletion and threatened exhaustion of the timber supply in the more thickly populated sections of the East has prompted several of the states to initiate action looking toward the conservation of their timber resources. As far back as 1880, a forestry commission was appointed in New Hamps.h.i.+re to formulate a forest policy for the State. Vermont took similar action two years later, followed within the next few years by many of the northeastern and lake states.
These commissions were mainly boards of inquiry, for the purpose of gathering reliable information upon which to report, with recommendations, for the adoption of a state forest policy. As a result of the inquiries, forestry departments were established in a number of states. The report of the New York Commission of 1884 resulted in forest legislation, in 1885, creating a forestry department and providing for the acquisition of state forests.
Liberal appropriations were made from time to time for this purpose, until now the state forests embrace nearly 2,000,000 acres, the largest of any single state.
New York state forests were created, especially, for the protection of the Adirondack and Catskill regions as great camping and hunting grounds, and not for timber production. The people of the state were so fearful that through political manipulation this vast forest resource might fall into the hands of the timber exploiters, that a const.i.tutional amendment was proposed and adopted, absolutely prohibiting the cutting of green timber from the state lands. Thus, while New York owns large areas of state forest land, it is unproductive so far as furnis.h.i.+ng timber supplies to the state is concerned. It is held distinctly for the recreation it affords to campers and hunters, and contains many famous summer resorts.
State forestry in Pennsylvania began in 1887, when a commission was appointed to study conditions, resulting in the establishment of a Commission of Forestry in 1895. Two years later, an act was pa.s.sed providing for the purchase of state forests. At the present time, Pennsylvania has 1,250,000 acres of state forest land. Unlike those of New York, Pennsylvania forests were acquired and are managed primarily for timber production, although the recreational uses are not overlooked.
The large areas of state-owned lands in the Lake States suitable, mainly, for timber growing, enabled this section to create extensive state forests without the necessity of purchase as was the case in New York and Pennsylvania. As a result, Wisconsin has nearly 400,000 acres of state forest land, Minnesota, about 330,000, and Michigan, about 200,000 acres. South Dakota, with a relatively small area of forest land, has set aside 80,000 acres for state forest. A number of other states have initiated a policy of acquiring state forest lands, notably, New Hamps.h.i.+re, Vermont, Ma.s.sachusetts, Connecticut, New Jersey, Maryland, and Indiana, each with small areas, but likely to be greatly increased within the next few years under the development of present policies. Other states are falling in line with this forward movement. There are but 4,237,587 acres in state forests in the United States. This is only 1-1/2 per cent. of the cut-over and denuded land in the country which is useful only for tree production. The lack of funds prevents many states from embarking more extensively in this work. Many states set aside only a few thousand a year; others, that are more progressive and realize the need of forestry extension, spend annually from one hundred thousand to five hundred thousand dollars. Foresters are, generally, agreed that as much as 25 per cent. of the forest land of every state should be publicly owned for producing large sized timber, requiring seventy-five to one hundred years to grow, and which the private owner would not be interested in producing.
National, state, or communal forests must supply it. All of these combined comprise a very small part of the forests of most of the states, so that much larger areas must be acquired by the states and the national government to safeguard our future timber supplies.
Not less than thirty-two states are actually engaged in state forestry work. Many of them have well-organized forestry departments, which, in states like New York and Pennsylvania, having large areas of state forests, are devoted largely to the care and protection of these lands. In other states having no state forests, the work is largely educational in character.
The most notable progress in forestry has been made in fire protection. All states having forestry departments lay especial emphasis upon forest protection, since it is recognized that only by protecting the forests from fire is it possible to succeed in growing timber crops. In fact, in most cases, the prevention of fire in itself is sufficient to insure re-growth and productive forests. Pennsylvania is spending $500,000 annually in protecting her forests from fire. The cooperation of the Federal Government, under a provision of the Weeks Law which appropriates small sums of money for forest protection, provided the state will appropriate an equal or greater amount, has done much to encourage the establishment of systems of forest protection in many of the states.
[Ill.u.s.tration: SOWING FOREST SEED IN AN EFFORT TO GROW A NEW FOREST]
The enormous areas of denuded, or waste land in the various states, comprising more than 80,000,000 acres, which can be made again productive only by forest planting, present another big problem in state forestry. Many of the states have established state forestry nurseries for the growing of tree seedlings to plant up these lands. The trees are either given away, or sold at cost, millions being distributed each year, indicating a live interest and growing sentiment in re-foresting waste lands.
