Scaling Logs 



"The present policy of scaling quantity of sound material rather 

 than quality of material in the log is more strongly emphasized; 

 also that overrim is considered a factor in appraisals and not in 

 scaling. 



In making deductions for defects in the log, provision is made 

 that the sound material must be of at least the minimtmi length of 

 product manufactured from the species in standard milling prac- 

 tice in the region and at least four inches wide. 



An exception to the requirement that all logs over 16 feet 

 will be scaled as two or more logs was extended to 17 and 18 foot 

 mining timbers on the Black Hills Forest. 



Some changes relating to procedure were made in the instruc- 

 tions for measuring, numbering, and stamping logs. 



A change was foimd necessary in the rule of thumb given for 

 center or circular rot on p. 19. Also, in applying the cull tables 

 for defect, a slight allowance in excess of the dimensions bounding 

 the actual defect is provided for. 



No deduction was made previously for curve or sweep in logs 

 over 16 feet long. The revised instructions provide that deduc- 

 tions will be made for curve or sweep in logs of any length to the 

 extent that material in them cannot be used for boards of the 

 minimum length utilized in the milling practice of the region. 



A uniform percentage allowance of difference between check 

 scale and original scale was changed to a graduated standard 

 depending upon the percentage of defect in the log."

One hears a great deal nowadays about the progressiveness of 

 American business men ; but when one considers the increased yield 

 from the use of cups in lieu of the old-fashioned boxes, it is sur- 

 prising that less than a third of the operators have adopted the 

 more modern, and less destructive, cup system. To obtain a 

 keener insight into the relative advantages of cups and boxes, 

 it would have been more conclusive, to be sure, if Schorger and
