LOG GRADES 



On Puget Sound, Fir logs are classed in three grades, 

 Flooring, Merchantable and No. 2. On the Columbia these 

 grades are designated as No. 's 1, 2 and 3. 



Flooring logs must measure not less than 30 inches 

 in diameter at the small end and saw out 50% or more of ab- 

 solutely clear, vertical-grained lumber, free from pitch 

 pockets, heart knots and excessive twist. 



Merchantable logs must be not less than 16 inches in 

 diameter at the small end and contain only a limited number 

 of knots, which must be tight and sound and not large enough 

 to materially weaken the lumber. 



No. 2 logs are logs lower than Merchantable in grade 

 from which marketable, rough lumber can be cut. 



On Puget Sound, where these rules have been applied, 

 the average boom of logs grades 30% Flooring, 50% Mer- 

 chantable and 20% No. 2. 



Spruce and Pine are graded the same as Fir. 



Cedar is graded into lumber logs and shingle logs. A 

 lumber log must approximate 50% clear lumber and must be 

 of sufficient size to have a well defined grain. 



Hemlock, Larch, Silver and White Fir, and other 

 classes of North Pacific Coast timber should be classed into 

 two grades. No. 1 logs and No. 2 logs, the former being such 

 as will cut 50% or better clear lumber and the latter such as 

 will cut only common marketable lumber.
