LOGGING IN THE DOUGLAS FIE REGION. 
145 
near the railroad and the other end was taken up the hill, passed 
through a block suspended to a guyed tree about 25 feet from the 
ground, and made fast to a stump. Two stops (fig. 50) were clamped 
on the standing line, one at the top where the logs were picked up, 
the other at the foot where the logs were landed. 
A carriage of the design shown in figure 50 was used, the snubbing 
line leading through it to the load. 
A 10 by 12 inch wide-drum yarding engine, on which an extra 
wide brake had been installed, was set at the top of the slope and 
used to lower the logs. 
Any friction drum engine 
with braking power suffi- 
cient to hold the load can 
be used. A three-drum en- 
gine could be used both to 
yard and lower the logs. 
To get the full capacity 
out of the system, however, 
one should use a separate 
engine with a special brake 
drum. 
The load was hooked on 
the end of the snubbing 
line (fig. 51) and hoisted 
till a ball fixed on the 
snubbing line just above 
the hook engaged in a 
catch in the carriage. This 
catch held the load up. 
The snubbing- drum fric- 
tion was then thrown off 
and the load was snubbed to the landing place. At this point the 
carriage came in contact with the stop on the lower end of the line. 
This stop held the carriage and freed the snubbing line, allowing 
the load to be lowered to the ground. When the load was unhooked 
the signal was given to return the carriage to the woods. The ball 
on the snubbing line again came in contact with the catch of the 
carriage, releasing the carriage from the stop. 
* The following crew was used to operate the snubbing device : 
1 engineer. 
1 fireman. 
1 wood buck (half time). 
1 hooker on.
