1853  [Rossing involves] taking off the bark a few inches in width along the entire length of the trunk on the space that is to be lined, so that the black mark may be more distinctly seen by the scorers.
1854  In squaring large trees much of the finest timber is blocked off by scorers and lost.
1947  (1963)  The fitter came first, selecting trees large enough to make a stick, and sound from top to base. The faller laid axe to tree, making it fall in the most convenient direction for the next operation. The log maker took over next, trimming the log of its branches, and cutting off the top to a specified length. After him the scorer peeled the bark from the upper sides, stretched the cord the length of the log and marked the thicknesses to be sliced off to make a flat side. He then "scored" each side with an axe at close intervals, so the hewer could hew to the line.
