PREFATORY NOTE. 



The purposes of the Forest Service in collecting and compiling this record of 

 f. o. b. mill prices is to have a continuous statistical record of such prices of 

 the various commercial woods. The prices given are wholesale, based on actual 

 sales f. o. b. mill, for delivery outside of local territory. Only a few representa-

 made up from reports received from the largest manufacturers throughout the 

 country. 



The Forest Service wishes to acknowledge the courtesy of the manufacturers 

 for their prompt and efficient cooperation.
