defects as do not prevent its use as substantial structural ma- 

 terial. 



90. No. 2 COMMON DIMENSION may have knots not 

 necessarily sound, which do not occupy more than one-half 

 of the cross-section at any one point if located at the edge of 

 the piece, nor more than two-thirds of the cross-section if lo- 

 cated away from the edge ; smaller, loose, hollow or rotten knots 

 that do not weaken the piece more than the knots aforesaid ; 

 will admit rotten streaks, shake, wane, worm holes, split not 

 to exceed one-quarter the length of the piece, and other defects 

 which do not prevent its use without waste. 



91. Miscut 2-inch Common stock which does not fall be- 

 low \y 2 inches in thickness, or ^-inch scant in width, from 

 standard size shall be admitted in No. 2 Common, provided such 

 pieces are in all other respects as good as No. 1 Common at 

 point of miscut. 



92. No. 3 DIMENSION will include all pieces falling be- 

 low No. 2 Grade which are sound enough to use for cheap build- 

 ing material by wasting 25 per cent of each piece of one-third 

 of number of pieces in any item of a shipment, but it must not 

 be more than ^-inch scant of standard finished width nor 

 J^-inch scant of standard finished thickness. (See Sec. 28). 



ROUGH YELLOW PINE FINISHING. 



Widths. On stock width shipments of "C and Better" Fin- 

 ish, either rough or dressed, one or two sides, no piece should 

 be counted as standard width that is more than %-inch scant 

 on 8-inch and under; %-inch scant on 9 and 10-inch, or ^-inch 

 scant on 11 and 12-inch or wider. Such pieces should be meas- 

 sured as the next lower standard of width and not reduced in 

 grade. 



Lengths. Standard lengths are 4 to 20 feet, and in ship- 

 ments of mixed lengths 5 per cent of 8 or 9 feet in grade of "C 

 and Better" shall be admitted. 



(The above percentage is allowed in all shipments of mixed 

 lengths, even though the number of feet of each length be specific- 

 ally stated; 4, 5,' 6 and 7 feet lengths not to be included except 

 by special agreement.}
