Timber for Structural Purposes 



By E. A. Sterling 



Announcement The National Lumber Manufacturers As- 

 sociation, through its Engineering Bureau, 

 is preparing a series of technical publications on structural tim- 

 ber. The word "timber," in this case, is interpreted in its 

 broadest application to all wood products used in construction. 

 These bulletins will be available to all who are interested in 

 standard and economical wood construction. The possibilities 

 and advantages of lumber in modern structures, as well as its 

 limitations, will be fully and frankly outlined, and reliable in- 

 formation as to strength, durability, and other characteristics, 

 presented. Supplementing the information on the qualities 

 of timber as a building material, details of proper design, 

 working drawings, new developments, and similar data will be 

 published. Modern wood construction in its many engineering 

 phases will be presented on its own merits, with prejudice to- 

 wards no other building material. Many materials are embodied 

 in the best designed structures, each with individual merits 

 and special fitness for the purpose. 



Service for Where wood products are better or as good, 



Architects, or by proper treatment can be made equal to 



Engineers and any other material, it is the legitimate desire 

 Builders of the lumber industry that their selection 



and use shall be given full consideration. The 

 policy will be to present engineering data relating to timber 

 as a structural material, and in a spirit of helpful service to 

 advocate the use of wood in construction wherever it fully 

 meets all requirements of safety and economy. The informa- 

 tion the manufacturers are ready to give should result in mu- 

 tual benefit, since the thoughtful intelligent use of structural
