102 THE USE BOOK. 



An approved copy of the weekly abstract of the log scale in 

 large sales will be sent to the purchaser. 



Logs should be skidded for scaling if the cost of scaling will 

 be materially decreased by this requirement. 



All timber will be scaled by the Scribner " Decimal C " log 

 _rgj. This rule drops the units and gives the contents of a log 

 to the nearest ten. When the total scale of a log is desired, all 

 that is necessary is to add one cipher to the sum of the numbers 

 read from the scale stick, excepting the contents of 6 and 8 foot 

 logs, 6 and 7 inches in diameter. These are given as 0.5, which 

 multiplied by 10 gives 5 feet as their actual contents. 



Instructions to sealers. Measure diameters^inside^the ha.rk- 

 offhe diameter to the nearest inch above or below the 



^ 



Make proper deductions for defects in logs. 



Make no deduction for curve or sweep in logs over 16 feet 

 long. 



Logs and other timber which are so defective as to be abso- 

 lutely worthless should not be stamped. 



Scale logs over 16 feet long as two, or more lo^s T if possfoje 

 iiriengths^iot tess thnn12 f^et. 



The following table shows how the lengths should be divided 

 when scaling logs 18 to 60 feet long. The number of inches to 

 be added to the diameter at the small end of each log, to cover 

 taper, is placed under each length. 



For example, a 42-foot log 16 inches in diameter at the top 

 would be scaled as 



One 12-foot log with a diameter of 16 inches. 



One 14-foot log with a diameter of 17 inches. 



One 16-foot log with a diameter of 19 inches.
