Excerpt from Effect of Moisture Upon the Strength, and Stiffness of Wood The investigations of the mechanical properties of wood by the Forest Service are being carried out by several timber-testing stations, in cooperation with the University of California, Purdue University, the University of Oregon, the University of Washington, and the Yale Forest School. The general aim of these tests is not only to supply useful informa tion for engineers and architects, but also to determine the useful qualities and values for specific purposes of quick-growing woods, thus promoting the practice of conservative forest management, and to determine proper substitutes for material which is more valuable for uses other than those for which it is now employed.
