LOGGING IN THE DOUGLAS FIR REGION. 



101 



The country is mountainous, very rough, and badly broken up. 

 The slopes in general are steep. No rock outcrops or cliffs were 

 encountered. 



About 100,000 feet of Douglas fir, spruce, cedar, and hemlock per 

 acre were logged, 20,000 to 30,000 feet of hemlock being left standing. 

 The logs averaged about 36 feet in length and 1,900 feet in volume 

 when based on the camp scale, which was about 2 per cent lower 

 than the selling scale. 



The three yarders used during the year were compound geared, 

 new, and up to date. Two of them were 10 by 13 inch ; the other, 11 

 by 13 inch.

(4) The average labor cost of transporting the logs from the 

 stump to the landing at a camp along the Columbia Eiver in 1912 

 amounted to $1,189 per thousand feet. It is not possible to state 

 the average distance from the stump to the landing. A large per- 

 centage of the timber was double hauled; some of it was triple 

 hauled. 



The chance from the standpoint of the ground was about an 

 average one, as the country is not particularly rough or badly 

 broken up. From the standpoint of brush, rotten stumps, and down 

 timber it was a bad one. The average minimum yarding distance 

 was about 900 feet. 



About 45,000 feet per acre were cut, mostly hemlock. The trees 

 averaged about 32 inches in diameter at breast height. On the 

 average three 32- foot logs were cut from a tree. 



The average output per yarder per yarding day amounted to 

 57,000 feet, the logs averaging about 650 feet in volume. The 

 yarding time on which this output was based includes breakdowns, 

 moves, etc., which did not take more than five hours. 



The crew consisted of 1 hook tender, 2 rigging slingers, 2 choker 

 men, 1 signalman, 1 sniper, 2 chasers, 1 engineer, 1 fireman, 1 

 wood buck, and 1 branding man.
