Work at the Eastern Forest Products Laboratory of Forintek Canada Corp. in fundamental and applied research is highly varied. The laboratory's facilities and equipment reflect this need for specia- lization. Its equipment is as basic to lumber production as saws, cutters, and dry kilns, or as complex as a steam press or fluidized -bed gasifier. These facilities allow researchers to carry out chemical, physical, and biological analyses of wood. Similarly, evaluation of wood products, and the processes by which they are made, is aided by laboratory and commercial-scale testing equipme- nt. In each area of research, the EFPL facilities assist research- ers in developing new, innovative systems and products. The indus- tries and governments that Forintek serves are the direct benefici- aries of this valuable resource. The following pages outline the key facilities and expertise available at Forintek's Eastern Forest Products Laboratory.
Wood drying is an essential step in the manufacture of most wood products to minimize the development of defects such as warp and checking. Kiln-drying under controlled conditions of temperature and humidity is the most widely used method for removing moisture from wood and achieving a low, uniform moisture. Many topics relevant to lumber drying are discussed in this manual: wood structure and wood-moisture relationships, drying methods, kiln types and instrumentation, treatment of logs and lumber prior to drying, kiln schedules and drying defects. Graphic data tables dealing with wood properties and wood-moisture relationships at various temperature are provided for hardwoods and softwoods utilized in Eastern Canada.

The southern regions of Eastern Canada appear to offer excellent potential for the development of industries based on hybrid poplar as a raw material. These southern regions offer an abundant supply of marginal agricultural land suitable for growing hybrid poplars; wood-using industries are already established here and are experiencing shortages in raw material supply; road and rail networks provide established transportation facilities and there is an abundant supply of labour including a substantial number of workers currently unemployed. More than a decade of genetic and silvicultural research experience with hybrid poplars now exists in Eastern Canada. Programs to promote the planting and culture of hybrid poplars are established in Ontario, Quebec and the Maritime Provinces. The most pressing need for research at present appears to be in evaluating properties of the raw material and in process and product development to optimize its utilization.
