This method was made possible by the discovery that the relationship of sawing time to log diameter and length was the same for all mills, regardless of actual production rate. This relationship is shown in table 11. In this table the time required to saw a 7-inch, 12-foot log is taken as 100; the times for other sizes are expressed as

PINE HARDWOOD 1946 1947 1949 1950 YEAR 951 1952 1953 Figure 31.—Pulpwood production in the Southeast, 1946-1953. This method was made possible by the discovery that the relationship of sawing time to log diameter and length was the same for all mills, regardless of actual production rate. This relationship is shown in table 11. In this table the time required to saw a 7-inch, 12-foot log is taken as 100; the times for other sizes are expressed as ratios of the 7-inch, 12-foot time. Thus, if a mill takes 60 minutes to saw a thousand board feet of lumber from 14-inch, 8-foot logs, it should take ^mp x 60 = 71 minutes per thousand to saw 5-inch, 12-foot logs. A faster mill that required only 30 minutes for 14-inch, 8-foot logs should take 35 minutes for 5-inch, 12-foot logs. Since sawing cost varies directly as sawing time, the ratios apply to it equally well. - 41 -.
