LOGGING IN THE DOUGLAS FIR REGION".

another. There is no disagreement, however, as to what in a general 

 way constitutes a proper method, since all agree that it should be 

 adapted to the conditions; that it should facilitate and not delay 

 yarding; and that it should do the w^ork at a minimum cost. 



PARBUCKLE METHOD. 



Fig. 60. — Common type of deck landing 



Logging jacks in connection with skids or landings were first used 

 to load logs in the region. This method, being slow, was soon super- 

 seded by the parbuckle 

 method, which resembles 

 the cross-haul method of 

 the East. The parbuckle 

 method is still extensive- 

 ly used in the Grays Har- 

 bor countr3^ One hun- 

 dred thousand feet of 

 timber per day can be 

 loaded satisfactorily with 

 it where the logs average 

 2 or 3 feet in diameter 

 and 40 feet in length. It 

 requires a more elaborate 

 and costly landing than 

 other loading methods. 



A gin pole is erected on the side of the track opposite to the land- 

 ing, to which a single sheave loading block is attached about 30 

 feet from the ground. The loading line, leading from the drum that 

 furnishes the power, passes through the loading block, then around 

 the logs to be loaded, and thence over the car to the base of the gin 

 pole where it is hooked. When the power is exerted on the line the 

 log is rolled from the landing to the car. 



SINGLE GIN-POLE METHOD. 



In many cases the loading rig consists of a single gin pole about 

 60 feet in height, a main loading line, crotch lines, and hooks, tongs, 

 or slings, the power being furnished by a loading drum on the read- 

 ing or yarding engine or by the main drum of a separate loading 

 engine (fig. 60). The gin pole is erected on the side of the track 

 opposite the landing and just far enough from the track to 

 permit the passage of cars, and with the top, or the part to which 

 the rigging is hung, over the center of the track. A 1-inch main load- 

 ing line, leading from the engine, passes through a 14 by 2 inch 

 corner block at the top of the gin pole, and then down to the log. 

 Two lines, called crotch lines, from 25 to 30 feet in length, depending 

 on the length of the logs and whether loading hooks or tongs are
