In 8 of 15 comparisons by tree species (6 Australian and 9 American), log volumes were estimated with more precision when the interlog position for measuring cross-sectional area was located at the midvolume (centroid) position rather than the midlength (Newton) position. It is concluded that the centroid of a tree or log defines a position of special significance for estimating volume. A formula is developed for estimating log volume based on measurements of log length and diameter at both ends of the log and at any intermediate position. For. Sci. 38(1):187-191.
