about $11.50. The figures indicate the various factors considered in 

 logging and manufacture and the cost of operations in cutting 16 

 million feet of shortleaf pine during a period of 4 years with 10 set- 

 tings of a mill having a daily capacity of 20 thousand feet. The 

 timber runs 2 to 3 logs per tree and 8 to 10 logs per thousand, and 

 occurs mostly either in small groups or widely scattered over an area 

 of 18,000 acres divided by a range of low mountains into two natural 

 logging units. The lumber haul to the railroad is from 5 to 11 miles.

The average cost of manufacture, exclusive of stumpage, was 

 $11.07 for five large portable mills averaging 3.5 million feet an-

 This cost of operation plus stumpage averaging $2.59 gives the total 



1 Fifteen thousand five hundred dollars minus one-half the investment retired in 3 years, 

 or $2,430, equals $13,070. Mill cutting 4,000,000 feet per year.
