DescriptionDuring April 1956, about 20,000 boards from 210 white fir and 290 western hemlock logs were measured at a lumber mill in western Washington. A magnetic drum, data-processing machine (type 650) was then used to calculate board-feet volumes by lumber grade for each log, and average board-foot volumes by lumber grade for each log diameter-class within log grades and within species. This first phase of the analysis was accomplished in 18 minutes of machine time once the board measurements were punched on cards.
