528 APPENDIX 



NO. 3 LOGS 



"No. 3 logs shall be 12 inches or over in diameter inside the 

 bark at the small end; not less than 16 feet long; having defects 

 which prevent its grading No. 2 and shall in the judgment of 

 the scaler be suitable for the manufacture of the inferior grades 

 of lumber. 



CULL LOGS 



''Cull logs shall be any logs which do not contain 50 per cent 

 of sound lumber. 



"All logs to be scaled by the Spalding Rule." 



"Note. — The various lumber tallies we have had of graded yellow fir 

 rafts have shown that, figuring 



No. I logs to contain 50 per cent of Clears, 

 No. 2 logs to contain 25 per cent of Clears, 

 No. 3 logs to contain no Clears, 

 there is a substantial overrun in the Clears obtained. 



" Note. — There are defects characteristic of logs from certain localities 

 for which it is impossible to make rigid rules."
