The average weight a cord of the rich stumpwood is 2,612 pounds, 

 as against 2,450 pounds for selected stumpwood, and 2,412, 2,400, 

 2,100, and 2,400 pounds for medium stumpwood, dead, down knots 

 and limbs, poor stumpwood, and green tops and limbs, respec- 

 tively. The corresponding yields of refined first turpentine are 16.8, 

 10.8, 10.7, 8.2, 8.5, and 3.1 gallons a cord; and the yields of total 

 merchantable turpentine are 19.8, 12.2, 12.7, 10.2, 9.7, and 3.8 gallons 

 a cord, respectively. With the exception of that from the green tops 

 and limbs, the yield of turpentine a cord follows the weight a cord. 

 The yields of pine oil and crude light oil, while not varying greatly,
