Available information on wetwood is presented. Wetwood is a type of heartwood which has been internally infused with water. Wetwood is responsible for substantial losses of wood, energy and production expenditures in the forest products industry. The need to evaluate these losses and to find ways to eliminate or minimize them is emphasized. Because of increased interest in wetwood, excellent opportunities exist in initiating a comprehensive program of research. Both short and long-term studies are included in the program with the short-term studies answering the immediate utilization problems created by wetwood and the long-term studies directed at examining the causes of wetwood and its control and prevention. This paper summarizes available information on the timber quality characteristic described as wetwood. Included are some possible causes of wetwood, where it occurs in tress, its properties, and the problems associated with it. The need for research to solve utilization problems associated with wetwood and the processing of logs and products containing it is recognized. With the report as a guide, a concerted research effort directed at the problem of wetwood can be organized. Such research will, in the short run, target in on and provide answers to wetwood-related processing problems presently plaguing industry and, at the same time, build a base of scientific knowledge with which to solve the problem of wetwood in timber stands.

At present, no single book adequately covers a basic understanding of wood book satisfies the need for such a work. It describes drying in practice. This the fundamental basis of kiln-drying technology, to enable forest companies to imFrove their drying operations as high-quality timbers become scarcer and of yesteryear can no longer be tolerated. Adaptive the wasteful practices is no longer good enough. Innovations change based on past experience of the material being dried and the processes require a sound understanding of drying. Newer techniques, such as the use of ultrahigh temperature sea soning and superheated steam under vacuum, require an even greater depth of physical understanding for these methods to be used effectively and economically. book provides a description of modern ideas about wood structure, This moisture movement and stress development, from which models of the drying process are developed to give the kiln operator important information about the course of drying under specified conditions, and thus a means is compared with practice wherever for rational process improvement. Theory possible.
