very wet. Brush can be burned more easily the first fall after
cutting than it can the second year, when many of the leaves have
fallen off. Brush burning has been done for 13 cents a thousand
in lodgepole, in the Medicine Bow National Forest, while it has
cost 22 cents in similar timber in the Yellowstone, and estimates
of 40 cents a thousand have been made for it in the Rockies. It
is generally admitted that brush can be most economically burned
by the same people who pile it. Recently several contracts have
been made in which the purchaser of the timber is required to pile
and burn the brush under the direction of forest officers, as has
been the practice in the Minnesota forest for some time. This will
lighten the total cost, and when the weather allows the brush to
be burned, as logging proceeds, the cost of burning will be offset
by the subsequent reduction in the cost of skidding.
"_Piling Without Burning_
"Brush piled properly, even though it is not burned, is a great
protection to the forest. Inflammable material is removed from
among the living trees, and should a fire occur it would be much
easier to fight. This is especially true where reproduction is
dense. Where openings are scarce piles should be made in the most
open places, and may be larger than those made to be burned."
SLASH BURNING
In many regions, especially in western Oregon and Washington, logging
debris is too great to make piling practicable. But except for
the damper localities close to the Pacific, the danger from these
immense accumulations is all the more excessive and, as we have
seen elsewhere, their removal is often desirable in order to further
reforestation by desirable species. Here the only course is to
burn the slashing clean.
This is a dangerous process unless every safeguard is employed.
Burning must be at a time in spring or fall when the slashing is
dry enough but the surrounding woods are not. Spring burning is
theoretically preferable, for it leaves less inflammable material
during the fire season. The first fire is also easier to control
then, because repeated experiments may be made, as the slashing
dries, until just the right conditions exist. On the other hand,
it is dangerous if there are many old stumps and logs in which
fire may smoulder to make trouble later. The exponents or fall
burning also argue that with care they can be ready to fire a very
dry slashing safely at the beginning of a rainstorm. Spring burning
seems to have the most advocates, but it is doubtful whether any
rule for all localities and conditions can be given with confidence.
Frequently failure at one season leads to postponement until the
next.
In either case the slashing can be given the advantage of the greatest
dryness with safety if it is surrounded by a cleared fire line from
which to work. Firing should be against the wind and if the wind
changes suddenly the opposite edge should be back fired. Previous
cutting of all dead trees and snags over 25 feet high is urgently
recommended. The camp crew should be held in readiness, well provided
with tools, as insurance against accidental escape.
Its probable restriction of insect breeding is a point of slash
burning likely to receive much future study. It is well known that
most forest-injuring insects prefer dying trees to vigorous ones;
also that the existence of an abnormal amount of such material
tends to abnormal breeding and consequent serious attack of vigorous
timber when the dead material becomes too dry to be inviting. It
is by no means impossible that the supposed immunity of Douglas
fir from insect injury may be largely due to the almost universal
destruction by fire of logging debris which would otherwise afford
ideal breeding places.
FIRE LINES
The division of mature forest into compartments separated by fire
lines is seldom practicable in this country. Nevertheless slashings,
deadenings and similar fire traps can very often be profitably
confined by the cleaning of strips which will not only stop or
retard the progress of a moderate fire but also facilitate patrol,
fire fighting or back firing. On favorable ground, where some choice
is offered, much may be done by falling timber inward so as to leave
few tops near the uncut timber and by the location of skidroads.
So far as practicable fire lines should be on the tops of ridges,
for, being slower to go downhill than up, fire is more easily
discouraged just as it reaches a crest. Bottoms of gulches are next
in strategic value, and midslopes least.
SAFEGUARDING EQUIPMENT
The most fruitful source of fires is spark-emitting locomotives
and logging engines. Much data has been collected showing that with
oil at a reasonable price its use is economical from a labor-saving
point of view as well as from that of safety. It reduces expense
for watchmen, patrol, fuel cutting, firebox cleaning and firing.
And since it is an absolute prevention, while all other measures
merely seek to minimize the risk, it is probable that even where
the cost of the oil more than balances these savings it will save
in the long run by averting a costly fire.
Where the use of oil cannot be considered, spark arresters are
essential. The argument that they prevent draft is not worth attention.
It is greatly exaggerated by engineers and firemen prejudiced against
innovation or too inattentive to keep their fires up properly and
consequently unnecessarily dependent on occasional forced draft.
The slight disadvantage involved by the modern improved arrester
is not to be compared with the importance of the safety acquired.
In addition to spark arresters, which may fail or be out of order,
logging engines using fuel other than oil should be provided with
a constant tank or barrel supply of six to twelve barrels of water
and 100 feet of hose with proper pumping attachment. With this a
spark fire can be promptly soaked out beyond danger of invisible
smouldering in rotten wood or duff. When conditions are dangerous,
careful loggers send a man back to each donkey-setting between
supper and bedtime to look for possible fires that were not seen
when the crew left. Many keep a watchman on the rounds all night.
Railroad rights of way can usually be kept cleaned and burned at
a cost far less than that of otherwise frequent shutdowns of the
entire camp to fight fire or rebuild bridges, to say nothing of
loss of timber.
PATROL
The best way to prevent fire is to prevent it. Putting out fires
already started is better than letting them burn, but as the real
foundation of a protective system it is about like lowering a lifeboat
after the ship has struck. Only by patrol can the incipient spark
or camp fire be extinguished before it becomes a forest fire that
has to be fought, taking hours or days instead of minutes. One
patrolman can stop 100 incipient fires easier than 100 men can
stop one big fire. Fires in the forest may never be wholly averted,
but patrol will prevent them from becoming "forest fires."
This is why the progressive lumberman no longer waits till forced
to layoff his crew to fight, spending in a day or two a patrolman's
salary for a season, shutting down his road and mill for lack of
logs, and perhaps in spite of all losing several thousand dollars'
worth of timber and equipment. It is also why the progressive
non-operating owner no longer considers fire loss the act of God,
to be reckoned as an investment risk of several per cent. The man
who does not patrol his timber nowadays is like a millman who hires
no watchman, has no hose or sprinkler equipment, and carries no
insurance. He _may_ escape loss, but by not making a reasonable
effort to insure against it he takes a course practically unknown
with other forms of property.
Modern fire patrol is systematic. Trained and organized men have
definite duties. Tools, assistance and supplies are available at
known points and without delay. Trails and look out stations, often
supplemented by telephone lines, give the greatest efficiency with
the least number of men. Above all, the system is based on the
fact that results are most truly measured not by the number of
fires extinguished but by the absence of fire at all. Settlers,
campers and lumbermen are visited, cautioned and converted. In
short, the patrolman has a certain area in which to improve public
sentiment. His success in this is worth more than efficiency in
fighting fires due to lack of such success. A system devoted to
mere fire fighting to be adequate must grow larger as time goes
on. One devoted to preventing fire may be reduced, as time makes
it successful.
The cost of efficient patrol varies so directly with the risk that
it is almost constant as an insurance investment. Where prevalence
of fire, difficulty of handling it, etc., make the cost per acre
comparatively high, there is equivalent certainty of greater loss
if this sum is not spent. Where the owner is warranted in believing
his risk small it costs but a trifle to provide sufficient patrol
to insure against it. One to 3 cents an acre is spent in the great
majority of successful patrols in ordinary seasons.
ASSOCIATE EFFORT
One of the first lessons learned from the establishment of private
patrol in the West was that both efficiency and economy are obtained
by co-operation between owners. Obviously if one patrolman can
cover the holdings of several, it is foolish for each to hire a
man. If a fire threatens several tracts, it is better to share the
expense of labor hired to put it out. The same is true of building
trails, buying tool supplies, etc. This has led to the forming of
associations which at a minimum cost to each member accomplish
the many tasks of finding suitable men, having them authorized
by the State, supervising and supplying them, paying emergency
expense, opening trails, etc. Each member pays his share upon the
acreage he represents.
These associations offer other important advantages besides the mere
cheapening of work. They are admirably adapted to modifying the cost
to fit the season. Beginning in spring with an assessment to cover
putting the whole territory under the essentials of supervision and
patrol, they can add men just as required by the progress of dry
weather and reduce again in the fall. Men can be centralized at
danger points better than through individual effort. Exceedingly
important is the means they afford of bringing in the non-resident
owner, the small owner who is not warranted in employing anyone
alone, and the non-progressive owner who would otherwise do nothing
but is ashamed to stay out of a general movement.
No tract can be safely considered as an independent unit. _No protection
confined to it alone is as good insurance as the removal of risk
from the district within which it lies._ Fire is no respecter of
section lines. There is always danger of unusual weather in which it
may travel a long distance. It is far better to secure the maximum
general safety in the locality than to have guarded tracts alternating
with fire traps. Moreover attention to individual tracts does not
improve surrounding conditions, and the latter may easily become
so bad as to make the cost of individual patrol, as well as the
risk, far overbalance any financial disadvantage at present through
co-operation.
Again, the public is far more likely to take kindly to the enforcement
of fire laws by an association than to the action of an individual
owner against whom some prejudice may exist. Associations greatly
simplify co-operation with State and Government in fire work and
tend to bring about appropriations for the purpose. They enable
uniform and concentrated effort to improve sentiment and legislation.
This booklet and the other work done by the Western Forestry &
Conservation Association was made possible by the existence of
the local organizations it represents. Their independent local and
State effect has been marked.
The bad fire season of 1910 was a supreme test of the associations
of the Pacific Northwest. They kept the bad fires in their immense
territory down to a number which can be counted on the fingers
and their losses were comparatively insignificant. Yet under the
weather conditions which existed the thousands of fires they
extinguished would certainly otherwise have swept the country and
caused a disaster probably unparalleled in American history.
REFORESTATION AS A FIRE PREVENTATIVE
However progressive the preventive policies adopted, the race between
them and the increasing sources of hazard resembles that between
armor plate and ordnance in the construction of battleships. While
for a given population engaged in pursuits endangering the forests
the risk lessens, the total activity increases at a rate which
makes the smaller proportionate risk as great in actual measure.
This is particularly true of the growth of slashing areas. The
virgin forest becomes more and more and checkered by burned and
cut-over deadenings, veritable fire-traps open to sun and wind,
and, especially west of the Cascades, usually covered by inflammable
debris, brush or dead ferns. Each year brings nearer the time when,
unless something is done, such will constitute the majority of
once forested land and the uncut timber will remain like islands
in expanses of extreme danger.
Next to cultivation, which but a small percentage will receive,
the safest insurance against recurring fires in these cut-over
areas is a thrifty young second growth. It shades the ground, keeps
out annual vegetation that furnishes fuel when dead, and will itself
carry none but such furious crown-fires as would be practically
unknown were there no openings for them to gain headway in. This
is less true of pine, but the very best protection which can be
given a tract of merchantable fir is a strip of 10 to 50-year second
growth surrounding it.
Whether regarded from the owner's standpoint or that of the public,
reforestation should be considered as a protective measure of extreme
importance. Actual expenditure to obtain it may easily be profitable
for this reason alone, for once established it will decrease the
cost of patrol thereafter. Were all cut-over land in the Northwest
immediately restocked, the fire hazard would be enormously reduced.
CHAPTER V
FORESTRY AND THE FARMER
CUTTING METHODS
If there is anyone for whom the practice of forestry is practical
and profitable, it is the farmer who owns the timber he uses for
fuel or other purposes. His supply of the most suitable material
is almost always limited and in any case his method of using it
is practically certain to influence his permanent labor expenses.
Nevertheless, especially in well-timbered regions, cutting is apt
to be with but two considerations--the quickest clearing of land or
the easiest immediate fulfillment of some need for tree products--and
the passage of a few years brings realization that this early
thoughtlessness must be paid for at a high price.
In the first place almost all timber of a commercial species has
real and increasing value. If it is young, this value is increasing
doubly because of growth. Varying greatly, of course, young timber
in the Pacific Northwest very often adds from 500 to 1,000 board
feet to the acre annually. This annual gain is taking place even
if the timber has not reached merchantable size, being like coin
deposited in a toy bank which does not open until full. And this
is true whether the ultimate use may be for fuel, poles, or salable
material like tie or saw timber.
Too much land is cleared of young growth, merely because such clearing
is easy, which is of such low value for tilling or even pasture that
its use for these purposes does not pay as well in the long run
as would its use for growing timber, especially when the investment
of clearing is considered. The resulting expanse of charred stumps
and logs, producing little but ferns, is a small farm asset at
best. The timber it would grow may eventually be a large asset.
And the labor of clearing applied to a smaller tract of good land
is sure to bring greater returns. An illustration is furnished
by two tracts near the end of a recently completed railroad in
western Washington. Twenty years ago a settler slashed a large
area of presumably worthless sapling fir adjoining his tillable
bottom land, set fire to it, piled and burned the remaining poles,
"seeded down" a pasture, and enclosed it by an expensive cedar
rail fence. The pasture, never useful except in early spring, grew
up to ferns, and was finally abandoned. Even the fence was moved.
The settler on the next claim left his part of the same sapling
growth to grow and this year sold the timber alone for $1,000 to
a tie mill which came into the neighborhood with the railroad. The
moral of this does not apply to cutting alone, but argues equally
for preventing fire in second growth.
It is also poor economy, if mature timber exists, to cut rapidly
growing young timber for fuel because it is nearer the house or
easier to cut. The former has become stationary in production,
while the latter, if left, is earning money by growing in quantity
and quality. If young timber must be used, and the land is not
worth actually clearing for cultivation or pasture, it is usually
far better to thin out the poorest trees, thus leaving the remainder
stimulated to a more rapid growth, which will soon replace those
removed, than to begin on the edge and take everything.
There is no reason why a certain poor-soiled timbered portion of
the average claim should not be considered as a permanent wood
lot, to be treated with the same interest and pride in making it
produce the greatest quantity of forest products for sale or use that
the owner accords his fields. With this point of view established
and consequent study given the subject, it will also be easier to
decide how large this portion should be. In many cases the result
will be abandonment of the idea that all forest growth is an enemy,
to be destroyed on general principles without calculating what
actual profit there is in destruction.
Another point often overlooked in the Pacific Northwest, because
of our local tendency to consider the forest only as something to
struggle against, is the exactly opposite influence of properly
placed tree growth upon sale values if the prospective buyer is
from the East or from our own cities or tree-less regions. Such
are attracted strongly by the grove-like effect of a few trees left
around the house. Their desire for this is as strongly ingrained
as the average local resident's desire for a completely free outlook
to mark his victory over unfriendly nature. The appeal a place
makes to a buyer as a pleasant home has frequently as important
an influence on his decision as its purely practical merits.
His judgment of the latter, however, is also affected by his earlier
environment. If he has lived where farming land is open, evidences
of the labor of clearing are discouraging. The untouched forest,
being totally beyond his capacity to estimate the labor its removal
entails, repels him less than stumps, logs, desolate burnings and
like detailed evidences of the work which lies before him. This
is another reason why the clearing of clearly fertile land may
be better business than the half-clearing of land perhaps best
suited for forest growth anyway. Again, not fully realizing the
plentifulness of forest products in the new locality, he may actually
overestimate the value of an attractive piece of forest land showing
evidence of the thoughtful care suggested in a preceding paragraph.
USE OF FIRE
Above all, it pays the settler in wooded regions to be careful
with fire. Properly directed and confined, fire is necessary in
clearing land. But there is no profit in allowing uncontrolled
fire to spread from the actual clearing to create a snarl of dead,
decaying and falling trees and underbrush. It is usually harder
to extend the clearing into such ground than into green timber.
