BULLETIN 11, U. S. DEPARTMENT OF AGRICULTURE. 



Table 34 shows the cut in board feet of flitch and of inch lumber from 4-foot logs for 

 crate and box lumber. Measurements taken on 1 cord of stacked bolts, the diameter 

 and amount of lumber actually cut being recorded separately for each bolt, give the 

 following results: Bolts ranging 3 to 6 inches in diameter between bark at the small 

 end will cut out 510 board feet of flitch per cord, or if sawed into inch boards will cut 

 out 390 board feet; bolts 6 to 9 inches in diameter will saw out 600 board feet per cord, 

 or if cut into inch boards will cut 500 board feet; a mill crew of four (one sawyer, one 

 engineer and fireman combined, and two men to help in handling the bolts and the 

 lumber) can readily saw up 5 to 10 cords a day, yielding 2,500 to 3,000 board feet of 

 flitch, or 2,000 to 2.500 board feet of inch lumber in case sawed into the latter. 



Table 35 indicates how much more lumber can be sawed from logs cut into four sec- 

 tions than when sawed as 12-foot logs. The percentage increase of the former over 

 the latter 1 is especially marked in the case of logs of small diameters, but makes little 

 difference in lars;e diameters.
