occasioned by the reduction of the mill output because of the 

 additional time spent on sawing such logs. 



Improper Trimming Lengths. — Sufhcient attention is not paid 

 to the length into which logs are cut. They should be a few 

 inches longer than the standard because in sawing large logs it 

 may be impracticable for the sawyers to cut exactly at right 

 angles to the length and, further, logs are often damaged on the 

 ends in skidding and in transit to the mill. This extra length is 

 trimmed off in the mill and gives a straight, bright end on each

board. Three inches are regarded as sufficient for a log 16 

 inches and under in diameter and 4 inches for those of greater 

 diameter. 



Workmen become careless and often do not cut 50 per cent of 

 the logs of the proper length. Where less than 2 inches is left 

 for trimming length, the board is usually reduced 2 feet in length 

 at the mill, while on boards that are several inches too long the 

 loss is also great. Inaccuracy in measurements is due to careless 

 marking with the stick and to the use of a measure shortened 

 by accidentally chipping off the end with the marker's ax.
