註釋

"Most hardwood lumbermen recognize inherent advantages in manufacturing sawed timbers: higher overrun from reduced kerf loss; reduced sawing time and milling cost per unit of volume output; quicker return from the sale of green timbers; and no degrade loss from yard seasoning. They also see the disadvantages: lower prices than for most lumber grades; limited and fluctuating markets; and restricted suitability of logs for timber manufacture. Many sawmill operators who have never cut timbers are reluctant to venture into this field. Other lumbermen have had an unsatisfactory experience in producing sawed timbers and have vowed never to enter this market again. Yet the extra income from sawing timbers along with standard lumber should entice some progressive mill managers to seek these valuable but somewhat erratic markets. The purpose of this paper is to discuss those factors that affect the profitability of manufacturing timbers and show that the combined manufacture of both lumber and timbers will provide a greater daily income than the manufacture of lumber alone.
