The need to measure the volumes of all materials produced in the sawmilling process is becoming more important as the value of these materials increases. This paper introduces a geometric model with which to calculate the volumes of these materials with a minimum of data gathering. Methods to calculate the volumes of green lumber, dry lumber, green chips, green sawdust, and dry planer shavings are given. The mathematical and geometric theory making up the model is illustrated by equations and drawings. (Author)

Proceedings of a workshop co-sponsored by the USDA Forest Service, the State University of New York, and the Society of American Foresters. Presented were papers on the methodology of sample tree selection, tree biomass measurement, construction of biomass tables and estimation of their error, and combining the error of biomass tables with that of the sample plots or points. Also presented were papers on various aspects of biomass research currently being conducted in the United States, Canada, and abroad.
