Overruns - Southern Pine Logs
Overrun and underrun data were collected for the four major southern pine species during a series of grade yield studies in the late 1950's in Arkansas, Florida, Georgia, Mississippi, and South Carolina. Each of the 1,491 logs was carefully scaled by the Doyle, Scribner Decimal C, and International ¼-inch log rule. All logs were sawed on. circle mills and the variations shown are based on green lumber tallies for each log. Only full scale (sound) log data are shown in table 1. The small number of defective logs and their wide variation in overrun militated against their inclusion.
