Description |
Dark brown wooden log scaling ruler. Black numbers calibrated on each side and a metal plate nailed on the bottom. A small hole at the opposite end from the metal plate. The numbers on the narrow side are used to measure the log's inner diameter, and go from 1 to 41. "Scribner" in black near the metal plate on the wide side. The numbers on the wide sides closest to the metal plate are the length of the log. Used by starting at the number that corresponds to the length of the log and going along the ruler until the number that corresponds to the log's inner diameter. The number at this intersection represents the log's board footage. |
Provenance |
A log scale ruler is used to find board footage, an estimate of the usable lumber that can be obtained from a log. It is used by finding the intersection of the log's length and inner diameter on the chart on the ruler. This scaling ruler uses the original Scribner scale, used from 1846 until the early 1900s. |
