SCOPE OF THE STUDY. 



This report is divided into three parts. Part I relates to the species 

 of wood used by the wood-working factories in Pennsylvania, independent of 

 their particular uses and the factories purchasing them. There is a general 

 discussion of each wood, its range, and importance in the State as a lumber 

 tree, the proportion of the amount used grown within the State, and a brief 

 though particular enumeration of the properties of the wood. Uses are re- 

 ferred to only in a general sense by calling attention to the industries report- 

 ing the wood in large quantities. 



Part II concerns the wood-using factories of Pennsylvania which have 

 been divided into industries according to products manufactured. Following 

 this is a discussion of individual industries, referring to the products manu- 

 factured, processes of manufacturing, woods demanded, and the principal 

 qualities determining their use. In a majority of cases, the most suitable 

 wood for each particular purpose is known, but the second best of the avail- 

 able kinds is pointed out where possible, and in this way, as well as in 

 others previously mentioned, the report will prove valuable to wood users. 



Part III is a summary of wood uses, independent of any industry classifi- 

 cation or statistical data. In compiling this list, the Forest Service en- 

 deavored to arrange it to include every wooden commodity manufactured in 

 Pennsylvania. It constitutes the most nearly complete compendium of uses of 

 wood that has ever been arranged , and will be of particular value for reference. 

 Part III further includes the directory of the names and addresses of manu- 

 facturers, grouped according to industries, who supplied the information con- 

 tained in this report. The appendix presents data pertaining to Pennsyl- 

 vania taken from reports of the Bureau of Census, United States Department 

 of Commerce.
