    This article presents the results of a study to determine the place, time, and number of measurements that should be made to obtain dependable ratings of "average-bad" fire conditions without an excessive number of stations or observations. The author concludes that under the conditions prevailing in the Priest River Experimental Forest in northern Idaho a single measurement taken daily at noon at either a valley-bottom or a south-slope station is adequate for the rating of fire danger.
