Many methods for the utilization of pine 



Utilization stumps have been proposed and tried, and 



of failed; but the success of a newly in- 



Pine Stumps. vented and unpatented process has been 



announced by the Heald Manufacturing 



Co., of Laurel, Miss. After six months practical operation it 



is shown that a fair profit can be made and naval stores ojf 



good quality can be produced at lowest prices. The solvent used 



is gasoline and a cord of 4,000 lbs. of "fat" wood is made to 



produce. 



Resin 500 to 650 lbs $10.00 



Turpentine 15 gallons, 5.00 



Pine oil, 3 gallons, 3.00 



Total, 18.00 



Cost of production, 10.00 



$8.00 



A plant in which $50,000 is invested will have a capacity of 

 12 cords a day, and employs 16 men. The resin has been of 

 E grade and is now bringing $3.90 per bbl. ; the turpentine 

 has been accepted as water white and is bringing 36c per gallon. 



Southern Lumberman. 



A very neat method of getting out logs 

 Aerial by means of an aerial tramway is de- 



Tramway. scribed and well illustrated in The Timber- 



man of July, 1913- The tramway was used 

 in logging out five million feet of timber in Idaho where the 

 country was so rough that the cost of railroading made that 

 method prohibitive. It has a capacity of 500,000 feet daily and 

 costs $10,000 per mile for construction. The up-keep is com- 

 paratively light. 



Tannin content of any of the following 

 Tannin Contents species is high enough to warrant use of 

 Southern the bark if enough can be obtained and if 



Oak Barks. it will produce good leather.
