Abstract
In 1957 the Forest Service Log Grade Committee recommended a service-wide action program in log and tree grade research. Approval of the program late in 1958 resulted in the establishment of five species-oriented timber- quality research projects covering the several groups of commercially important timber species. The eastern softwood timber-quality project was activated in 1960. The initial objective of the project was to develop better log and tree gades for eastern white pine. This report presents the results of the initial research on tree grades.
