LUMBKR SIZKS AND GRADES 35 



Two-inch to G-inch inclusive, for both width and thickness, take off 

 3/8-inch SlSlE or S2S2E. 



Over 6-inch, for both width and thickness, take off J^-inch SlSlE 

 or S2S2E. 



Rough sizes were not stated for any stock except 1-inch, but are, 

 nevertheless, supposed to be of sufficient size when seasoned to a 

 maximum of 20 per cent moisture to surface to the actual sizes recom- 

 mended by the association for the stock in question. With but minor 

 changes the conference referred the sizes back to the manufacturers 

 with the request that they be officially adopted and put into practice 

 at once. 



September 2d was devoted to patterns and sizes of moldings. The 

 types of moldings were based largely on the recommendations of archi- 

 tects. The manufacturers and retailers wei^e mainly interested in 

 reducing the necessity of manufacturing and carrying stocks of little- 

 used patterns. It was believed that better sales would result through 

 concentration of a limited number of patterns recommended by archi- 

 tects designed to give approved artistic effects. With minor changes 

 the patterns were approved by the conference and referred back to the 

 lumber manufacturers for adoption. 



Association action on lumber grades and nomenclature is being de- 

 ferred until action is taken on sizes. In addition to nomenclature, the 

 work of the Forest Products Laboratory has been largely centered on 

 fundamental work, such as the definitions of defects and the determina- 

 tion of equivalent defects which are necessarily the foundation stones 

 in standardizing lumber grades. 



Standardization of building materials, such as lumber, has been a 

 long- felt need throughout the country, and the progress attained thus 

 far has not only been highly commended by national engineering bodies 

 and the consuming trade, but the final adoption of standard grades and 

 sizes will close a very progressive chapter in the history of the lumber 

 industry.
