According to the report of the Census Bureau, 

 the cut for the year 1910 of all eastern "yellow" 

 pines, (of which the greater part was long-leaf 

 pine), amounted to 14 billion board feet. This 

 represents about two-thirds of the total cut of 

 resinous woods throughout the entire country. 

 The consensus of opinion seems to be that in ordi- 

 nary lumber operations at least 60 per cent of the 

 actual wood in the tree is wasted in transforming 

 the same to sawed lumber, about 35 per cent 

 being lost at the mills in the form of sawdust, 

 slabs, edgings and shavings, and 25 per cent 

 remaining in the forest in the form of tree-tops, 

 branches, stumps, etc. (U. S. Dept. Agric,., Y. B. Sep. 

 534, 1910, p. 257). This would signify that the 

 waste amounted to 21 billion feet, as the census 

 figure refers to finished lumber. Assuming 1,000 

 board feet to be equivalent to 1 cord, this 

 would represent an annual production of 21 mil- 

 lion cords of waste resinous woods in the South. 

 The estimation by Veitch and Merrill (U. S. 

 Dept. Agric., Bur. Chem., Bull. 159, p. 24) of 8 

 million cords of waste resinous woods of all kinds 

 formed annually seems to be erroneous, as they 

 have apparently taken the census figure as repre- 

 senting 100 per cent of the actual wood cut. 



It is of course impossible to determine exactly 

 the total amount of long-leaf pine waste produced 

 each year. Furthermore, the waste varies widely 

 in oleoresin content and a large proportion would 

 be too lean to warrant treatment for the recovery 

 of resinous constituents. The effective utilization 

 of this class of wood waste by a variety of processes 

 would surpass the present production of the coun- 

 try in the items of low-grade papers (other than 

 newspaper),' rosin, rosin oils, turpentine, pine oil, 

 rosin spirits, wood tar, soft wood charcoal and 

 ethyl alcohol. 



Composition of Long-Leaf Pine 



The constituents of economic value existing in long- 

 leaf pine are the oleoresin and the wood itself. 

 The products actually obtained from the pine de- 

 pend on the methods of treatment.
