    Detection of forest fires while they are still small is so important in forest protection that studies of the visibility of forest fire smokes from lookout points has been one of the principal phases of the fire studies program of the Pacific Northwest Forest Experiment Station. One phase of fire detection is the personal efficiency of the lookout. The Station has studied methods of testing the eyesight of lookouts and the effectiveness of colored and smoked glasses in lessening eyestrain. The study of glasses, made by Richard McArdle, E. J. Workman, and George M. Byram, led to selection of a specific type of glare-reducing goggles. Such goggles are now being used by several hundred lookouts in Region Six. At the fire-control conference held in Spokane in February, 1936, these goggles were adopted by the Forest Service as standard equipment for all parts of the country.
