Height accumulation, a relatively new concept for determining volume of standing trees, proved efficient for rapidly computing cubic volumes of young, even-aged stands of southern pine. Volumes were estimated by deriving volume-basal area ratios from a small number of sample trees and multiplying by total basal area per acre. The Bitterlich Spiegelrelaskop was used for simultaneous determination of upper diameter points and their height above ground. Field work was simplified in comparison to that normally required for construction of local volume tables. The method permitted segregation and separate measurement of the distinctly different shapes, merchantable lengths, and volumes of cut and reserved trees--details of which volume tables usually take no account. The computation of stand volume required less time and effort than conventional means, and gave the accuracy desired for research purposes. The method is well adapted to use with electronic computers.

The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
