28 Forestry Quarterly. 



a fair average lot of logs, but no log was taken for which a 

 scaler would not allow full scale. About eighty per cent, of the 

 logs were sawed into inch boards, and the remainder into two 

 inch plank. All lumber was square edged. 



The mill was portable, with a capacity of about 10,000 Feet 

 B. M. daily. The saw was circular, and cut one-fourth inch 

 kerf. Edging and cutting to lengths were done as economically 

 as possibly, and there was little unnecessary waste in slabbing. 

 The minimum sizes were eight feet in length and four inches 

 in width. Even lengths and widths only were cut. Table i 

 gives the averages of the mill cut for logs of each inch diameter 

 class in the different log lengths. Table 2 gives corrected values 

 for Table i, obtained from curves.
