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.
