(a) In surveying or measuring logs, the county timber inspectors and their deputy county timber inspectors shall make such allowance for hollow, rotten, or crooked logs as would make them equal to good, sound, straight, and merchantable logs.
(b) All logs that are straight and sound are to be measured at their full size inside the bark at the small end.
(c) All logs over twenty-four feet (24') long not exceeding thirty-six feet (36') shall be scaled or measured as two (2) logs, allowing the rise from the first to the second log as may be required or as may seem proper in the opinion of the county timber inspectors or their deputy county timber inspectors.
