position and location of the defects visible 

 in any piece. The enumerated defects 

 herein described admissible in any grade 

 are intended to be descriptive of the 

 doarsest pieces such grades may contain. 



28. Lumber and timber sawed for 

 specific purposes must be inspected with 

 a view to its adaptability for the use in- 

 tended. Material not conforming to 

 standard sizes shown herein and that is 

 intended for agricultural implement com- 

 panies, wagon companies, car manufactur- 

 ing companies, railway companies, etc., 

 shall be governed by special contract and 

 inspection. 



29. The standard lengths are multiples 

 of 2 feet, 4 to 24 feet inclusive, for Boards, 

 Fencing, Dimension, Joists and Timbers; 

 multiples of 1 foot, 4 to 20 feet, inclusive, 

 for Finishing, Flooring, Ceiling, Siding, 

 Partition, Casing, Base, Window and 

 Door Jambs except as hereinafter speci- 

 fied. Longer or shorter lengths than those 

 herein specified are special. Special frac- 

 tional lengths, when ordered, will be count- 

 ed as the next higher standard length. 



30. The standard widths for lumber, 

 S. 1 S. or S. 2 S., or rough, excluding 

 Dimension, shall be multiples of 1 inch 

 3 inches and up in width. 



81. Stock width shipments of No. 1 

 Common and Better, either rough or 

 dressed on one or two sides, shall be 

 accepted as standard where not more than 

 20 % of any shipment is *4 inch scant on 8- 

 inch and under ; % inch scant on 9 and 10- 

 inch; 1/2 inch scant on 11 and 12-inch and 

 wider ; pieces narrower than the above, and 

 pieces in excess of 2Q% of the shipment 

 that are of the minimum measurement 

 above given, should be measured as of the 

 next lower standard width and not reduced 

 in grade (for width of No. 2 Boards and 

 Fencing, see pages 56 and 57 ; for width of 

 dimension see Sections 90 and 98.) 



32. Arkansas Soft Pine shall be classi- 

 fied as to grain as Edge Grain and Flat 

 Grain. 



Edge Grain has been variously desig- 

 nated as rift sawn, vertical grain, quarter 

 sawn, all being commercially synonymous 



DRESSED ARKANSAS 

 Sizes. Finishing shall be dressed to the 

 following : 



1-inch S. 1 S. or 2 S. to 13/16; 

 1%,-ineh S. 1 S. or 2 S. to 1% ; 



terms. Edge grain stock is especially de- 

 sirable for Flooring and admits no piece 

 in which the angle of the grain exceeds 45 

 degrees from vertical at any point. 



33. All dressed stock shall be measured 

 and sold strip count, viz.: Full size of 

 rough material necessarily used in its 

 manufacture. 



All sizes 1 inch or less in thickness shall 

 be counted as 1 inch thick. 



34. In standard manufacture of Fac- 

 tory Flooring, Decking, or thick dressed 

 and matched stock, and stock grooved for 

 splines, and for thick Shiplap, the finished 

 width shall be i/^-inch less over all than 

 the count or measured width of the rough 

 material used in manufacture, and the 

 tongue and lap shall be measured to de- 

 termine the finished width, and face meas- 

 ure shall not be standard. 



35. "Equivalent" means equal, and in 

 construing and applying these rules, the 

 defects allowed, whether specified or not, 

 are understood to be equivalent in damag- 

 ing effect to those mentioned applying to 

 stock under consideration. 



36. No arbitrary rules for the inspec- 

 tion of lumber can be maintained with 

 satisfaction. The variations from any 

 given rule are numerous and suggested by 

 practical common sense, so nothing more 

 definite than the general features of dif- 

 ferent grades should be attempted by rules 

 of inspection. 



37. Inspection of lumber is not an exact 

 science and a reasonable variation of opin- 

 ion between inspectors should be recog- 

 nized; therefore, a variation of not more 

 than 5 per cent upon reinspection should 

 not disturb the original inspection. 



38. Lumber must be accepted on 

 grade in the form in which it was shipped. 

 Any subsequent change in manufacture 

 or mill work will prohibit an inspection 

 for the adjustment of claims, except with 

 the consent of all parties interested. 



39. The foregoing general observations 

 shall apply to and govern the application 

 of the following specifications : 



SOFT PINE FINISHING. 



iy 2 -inch S. 1 S. or 2 S. to 1% ; 



2-inch S. 1 S. or 2 S. to 1% inches. 



These thicknesses also apply when S. 4
