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.
