Merchantability varies â with different species with business conditions and other factors« In cubic-foot scaling as in board-foot scaling there should, of course, be merchantability or minimum grade specifications which state that to be merchantable a log must have a minimum length of so many feet, a minimum diameter of so many inches, and not over a stated percentage of cull material. Definitions of merchant ability which now apply to board-foot scaling will in all probability be applicable in cubic-foot scaling.

This record should include the essential details for each log, such as the species, diameter, length, amount of defect, and net volume. Listing the log number, gross volume, and kind of defect is optional. The form of record might be some- what like the following: _ 20â.
