PRODUCTION OF LUMBER, T.ATU, AND SHINGLES EN I 15 



returns from the larger organizations are almost complete, [n 

 making the computations, careful consideration w fco all 



available data and the figures may be regarded as co ively 



correct. 



It is not practicable in this bulle'tin to distinguish fcfo 

 species which go to make up a given kind of wood, sue] How 



pine or oak, because no universal classification exists among the 

 lumbermen. The result is that tho several yellow pines are grouped 

 in a single table and the oaks are treated hi the. same maim 



Not all of the mills which reported their production returned mill 

 values of the lumber, but the figures given are those of more bhan 

 one-half of the 17,269 mills that scheduled data on their output.

Variations in the prices shown are directly attributable to conditions 

 affecting the mills located within the State, the principal factors 

 being the quantity and quality of the timber cut, proximity to con- 

 suming markets, and character of the stock produced. Comparison 

 and analysis of the prices returned on each schedule insured results 

 of considerable accuracy. 



YELLOW PINE. 



Under the broad classification of yellow pine is included the various 

 yellow pines grown in the eastern and southern sections of the United 

 States. The three species contributing chiefly to the aggregate, out- 

 put are longleaf (Pinus palustris), loblolly (Pinus tseda), and short- 

 leaf (Pinus ecliinaia).
