S2The availability of timber resources plays an important part in the location decision for the primary wood-using industrieslumber, particleboard, and woodpulp. This report contains the latest Forest Service statistics for the State of West Virginia. These data are based on a sampling scheme designed to get reasonable accurate data for areas smaller than the entire State. They are current as of January 1961.S3.

S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.

S2The purpose of this paper is to point out some of these interactions and to illustrate that bacteria, non-hymenomycetes, and hymenomycetes are all important in the processes that lead to decay and discoloration in beech, birch, and maple. Data from several studies are summarized.S3.

In 1962 a survey-type study was conducted to evaluate the performance of forest tree species in established plantings on strip-mine spoils of the Anthracite Region of Pennsylvania. Plantations representing a wide range of site conditions in all four anthracite fields were examined.

Because of the growing need for wood fiber in the pulp and paper industry there is an opportunity for sawmill operators to increase their income by converting hardwwood sawmill residues (slabs, edgings, and trim) to pulp chips. By selling wood chips and reducing residue-disposal costs, sawmills could improve their utilization of sawlogs. But to justify the installation of debarking and chipping machines, and to know what such machines could contribute to his business, the sawmill owner must have a thorough understanding of the costs involved in chip production. To help him in this we have made case studies of seven sawmills in southeastern Ohio, eastern Kentucky, and Tennessee, and have analyzed all the factos of cost involved in chip production.
