Excerpt from Lumber Manufacture in the Douglas Fir Region The low, intermediate, and high figure Of costs of operation, repairs, and supplies are meant to cover not the range for mills of any specific size but the general range for all classes, regardless Of size or type. SO far as pos sible, the effect of size or type of Operation has been mentioned with other factors bearing on such costs, but sufficient data was not available to bring out in each case the exact effect Of size of Operation on the particular cost item. The machinery and equipment prices are those in effect in 1916. The costs per thousand feet are in terms of the volume of finished product and not log scale or other temporary volumes. The drawings of machines and equipment are entirely for illustrative pur poses and must not be considered in any sense as an endorsement of the style or types shown.
