Log value—Dollars per thousand net Scribner log scale is a combination of the recovery ratio and the average lumber value. Increases in recovery ratio and differences in lumber grade recovery produce higher estimates of $/MNLS as time passes (fig. 14). The 1984 study produced the highest $/MNLS with the 1971 study next and the 1957 study the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Willits, Susan; Fahey, Thomas D.
