Bright, George A. 1913. Umatilla National Forest annual silvical report: relative merits of western larch and Douglas fir in the Blue Mountains, Oregon. 
Abstract: This report deals with Douglas-fir and western larch as they occur in the Blue Mountains of northeastern Oregon, especially on the Umatilla and Whitman National Forests. In that locality, they are the two species that were next in commercial importance to western yellow (ponderosa) pine. Both western larch and Douglas-fir had very little commercial use at the time this report was written – the reason was not that the wood of those species was bad, but that the wood of yellow pine, which was abundant, is exceptionally good in quality. The report also includes the following topics: technical qualities of larch, faults of larch wood, longevity of larch, natural enemies of larch, management of larch, technical qualities of Douglas-fir, forest types in which Douglas-fir is found, resistance of Douglas-fir to insects and diseases, management of Douglas-fir, growth and yield of Douglas-fir and western larch trees and stands, and a summary.
