PRODUCTION OF LUMBER, LATH, AND SHINGLES IN 1016.

returns from the larger organizations are almost complete. In 
making the computations, careful consideration was given to all 
available data a:ul the figures may bo regarded as conservatively 
correct. 
It is not practicable in this bulletin to distinguish the several 
species which go to make up a given kind of wood, such as yellow 
pine or oak, because no universal classification exists among the 
lumbermen. The result is that the several yellow pines are grouped 
in a single tablo and the oaks are treated in the same manner. 
Not all of the mills which reported their production returned mill 
values of the lumber, but the figures given are those of more than 
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 txda), and short- 
leaf (Pinus ecliinata).
