APPENDIX 527 



"No. 3 shall be 15 to 19 inches in diameter inclusive, fresh cut, 

 green, straight and free from knots, windshakes and other 

 defects; except that this grade may take logs 20 inches and up 

 in diameter with one to three small solid knots not exceeding 3 

 inches in diameter. 



"Walnut Logs. — Walnut logs shall be subject to special 

 agreement between buyer and seller as to size and grading. 

 No piece of timber will be considered a saw log, or will be 

 measured as such, that is smaller in diameter than 12 inches. 



" Spikes. — Seller of logs will be held responsible for damage 

 resulting from spikes, or pieces of iron in logs. 



"Brands. — -All logs should be branded before being brought 

 to market. Defacing, or changing of brands on logs, subjects

DOUGLAS FIR LOG GRADING RULES 



(Columbia River Log Scaling and Grading Bureau) 

 NO. I LOGS 



"No. I logs shall be 30 inches or over in diameter inside the 

 bark at the small end, reasonably straight grained, and not less 

 than 16 feet long; and shall be logs which in the judgment of the 

 scaler will contain at least 50 per cent of their scaled contents 

 in lumber in the grades of No. i and No. 2 Clear lumber. 



" In a general way it may be said that a pitch ring is not a serious grade 

 defect in a No. i log, provided its location and size does not prevent the 

 log cutting the requisite amount of Clears. The same applies to rot. 

 Pitch pockets, seams, knots, etc., are defects which impair the grade in 

 proportion to their effect on the amount of Clears the log contains. A No. i 

 log will admit a few small knots, but must be surface clear for at least four- 

 fifths its length; a few pitch pockets, as permitted in the grades of clear 

 lumber, but no combination of defects which will prevent the required 

 percentage of Clears. 



NO. 2 LOGS 



"No. 2 logs shall be 16 inches or over in diameter inside the 

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

 defects which prevent its grading No. i, but which will in the 

 judgment of the scaler be suitable for the manufacture of lumber 

 principally in grades of 'merchantable' and better.
