they are intelligible or not, and whether they allow one and

Three practices are common in
preparing lumber for use: To sell it to the workman in the
rough, just as it comes from the sawmill; to machine-plane
the pieces to thicknesses and widths such as the finished
pieces demand, so that only the lengths require the
attention of the worker aside from the making of the joints; and to mill-plane the stock on two surfaces to stock
thicknesses, but allowing the lengths and widths to remain
as in rough stock.
The first is cheapest in first
cost; the second is the most expensive because of the
frequent changes in setting the planing machine to the
different sizes. The third is most common, except where
there are to be a great number of pieces of a given size,
because it utilizes hand work and machine work to the best
