only 73 were less than 12 inches in diameter on the stump. Log 

 lengths ranged from 14-48 feet, with the long lengths predominat- 

 ing. From the 2,053 trees, an average of 51.3 trees to the acre, 

 were secured 3,128 logs, or an average of one and one-half logs 

 to each tree. The average production of each acre was 16,498 

 board ft. log scale.

In the longleaf pine districts, spurs are built 900 feet apart, 

 and the logs hauled 450 feet each way. The cost of putting in 

 a spur one mile long in this district is figured at $528, which in- 

 cludes the depreciation of steel, cost of bridges, trees, grading 

 and cribbing, and maintenance of the track. A spur one mile 

 long would haul the timber from approximatel}' 109 acres, mak- 

 ing the cost for each acre $4.85. As the timber averages about 

 17,000 feet to the acre, the cost for each 1000 feet would be 28 

 cents. With this as a basis, the cost of cutting and delivering 

 1000 ft. of logs at the mill may be given as follows :

On this basis it cost $1,517.79 to cut and deliver to the mill 

 the timber on forty acres of land.
