Available in PDF, EPUB and Kindle. Book excerpt: S2Ever since the quality-index (Q.I.) concept was introduced by A.M. Herrick in 1946, its importance as a measure of timber value has grown: and it has been used, not only in other research efforts, but also as a tool to be used by foresters and timber operators (Herrick 1946). We have recently employed the Q.I. concept in our rate-of-value-increase studies on nine tree species in the Northeast and recognized that, as a byproduct of this study, the log-quality indexes would be useful to timber operators. This paper briefly reviews the quality-index concept, presents log-quality index tables for a selected group of eastern hardwood tree species, and explains how timber operators can use Q.I. for evaluating the lumber that can be sawed from logs and trees. The Q.I. tables are based on two different lumber price reporting services and cover different geographic regions. Those species that occur in more than one region have a different Q.I. in each region. S3.

This book was released on 1970 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharum Marsh.) to increase the yield of sap collected for making syrup and sugar (2, 4, 5, 8). The explanation offered for this increase in sap yield is that microorganisms in the tapholes (7) cause premature decline and stoppage of the sap flow (1, 6), but that paraformaldehyde increases sap yield by inhibiting their growth (2). But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected and studied. This paper is a report on that study.S3.
