Page 36 - Under proper conditions, wood has proved itself good for centuries of service. Molds, stains, and decay in wood are caused by fungi, which are microscopic plants that must have organic material on which to live, and for some of them wood offers the required food supply. Their growth, however, is dependent upon suitably mild temperature and dampness. Most decay occurs in wood having a moisture content above the fiber- saturation point. Wood that is continuously water-soaked or continuously dry will...
