This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mean specific gravity values of longleaf, slash, loblolly, shortleaf, Virginia, sand, and white pines growing on some of the National Forests, in Region 8 are presented by National Forest and by State. ranges in specific gravity as well as the standard deviations are also presented. variation in mean specific gravity with geographic location is discussed for the four major southern pine species. the mean specific gravity values of longleaf, loblolly, and slash pine increased from North to South along the Atlantic Coast and from West to East along the Gulf Coast. the shortleaf pine sample showed no apparent geographic trends.
