daily output of from 30,000 to 35,000. A crew of one teamster, two 

 loaders, and a team is required, at a daily cost of $10. Besides the 

 horses, harness, and spreaders, the only equipment needed is two 

 peavies for the loaders and 80 feet of loading cable costing about $7. 



The most widely used method is by cable and "gin pole." It 

 seems best adapted to donkey logging, and is also used for loading 

 traction trucks. A gin pole, consisting of a log from 14 to 18 inches 

 in diameter by 40 feet high, is erected on the opposite side of the 

 track from the landing and guyed with five cables in such a manner 

 that the upper end is over the center of the track, A block is fastened 

 at the top of the gin pole and a three-fourths inch loading cable 

 passes through it from the loading drum of the engine. This cable 

 may terminate in a hook and be used in much the same manner as the 

 cross-haul, or it may terminate in a crotch line with two end hooks. 



Upon one traction logging operation where the loading is done at 

 the lower end of a horse chute, the gin-pole system is used, power 

 being furnished by a Dolbeer donkey engine. The crew consists of 1 

 engineer, 1 spool tender, 2 loaders, and 1 waterbuck, with a com- 

 bined labor cost of $14.40 per day. The average daily output is 

 60,000 and the average cost 24 cents per 1,000. This should probably 

 be increased by 2 cents per 1,000 for maintenance of the donkey and 

 other equipment. 



The gin-pole system is widely used where yarders are located at 

 landings along logging spurs. The best results are obtained with 

 cables terminating in a crotch line. The logs are lifted bodily in the 

 air and lowered in place upon the car. Motive power is commonly 

 furnished by a loading spool or a third drum upon the yarder. The 

 crew consists of a spool tender and two loaders, and the total daily 

 cost is 19. Such a crew is ample to handle the output of any yarder; 

 and usually no matter how small the daily output there can be no 

 reduction in the number of the crew. Thus the cost of loading 

 depends primarily upon the average daily output of the yarder. The 

 cost is as follows, according to the daily output: 25,000, 36 cents; 

 30,000, 30 cents; 35,000, 26 cents; 40,000, 23 cents per 1,000 feet. 



The cost of loading by this system at chute landings is cheaper 

 than when each yarder is at a separate landing on the railroad. The 

 reason is that, from two to five yarders being stationed upon a given 

 chute, logs are delivered in quantity up to the maximum capacity of 

 the outfit. The loading crew is the same as at a yarder, except that 

 for a daily output of 120,000 it must be enlarged by one top loader, 

 one loader, and one shoveler. The daily labor cost is therefore about 

 $18.50 per day, or 15 cents per 1,000. At 100,000 daily the cost is 

 about 19 cents per 1,000. 



A separate loading engine is probably better as a motive power 

 than a spool or drum upon the logging donkey. It may be either a
