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 secu
