The Gilmer system of turpentining has 

 New Method been inspected by a large number of lum- 

 of bermen and turpentine manufacturers. 



Turpentine This system distills crude turpentine di- 



Gathering. rectly from the tree by an air-tight cup. 



The tree is tapped without hacking and it 

 IS claimed that it does not injure the tree in the least and is as 

 rapid as the old method. A Union Naval Inspector made an 

 analysis of the ground showing that 748 pounds of crude tur- 

 pentine gave 530 pounds of resin and 148 pounds of spirits, 

 -equal to 13^ gallons to the barrel. This gave 19.78 per cent, tur- 

 pentine, 70.85 per cent, resin and 9.37 per cent, waste which is 

 .a gain of 18.54 per cent, over the old method.

A few years ago the turpentine privilege 

 Value sold for $3 per acre for a 3 year period 



of but at present the price averages about 



Turpentine $4-50. This is for stands of 10,000 to 12,- 



Limits. 000 feet. Privileges are usually based on 



a "crop" of 10,500 boxes at a price of $700 

 to $800. Many quarter sections average this number of boxes 

 but if more than 160 acres are required the cost varies from 

 ^2.50 up depending upon the cost of operation. Other factors 

 such as swampy or high ground, condition and size of timber, 

 -number of trees to the acre and general accessibility greatly af- 

 fect prices. 



American Lumberman, Nov. 12, 1910. 



Apple barrels are generally made of ash, 



Apple gum, or other hardwoods with elm hoops 



Barrels. as a standard. The stave is 28^ inches 



long with an average width of 5^ inches. 

 Six hoops are generally used but occasionally eight hoops are 

 used for special purposes. Coopers are careful to maintain the 

 uniform capacity of three bushels. Number 2 stock is generally 

 used for apple barrels ; white No. i stock is used for flour. In 

 the South where the heat is intense many plants use negro labor 

 v€xclusively.
