204 LOGGING 



The timber on this operation was cut from 24 to 32 feet long 

 and was felled without regard to the skidding direction. The 

 head spar and tail trees averaged about 700 feet apart with a 

 maximum of 1,000 feet; the number of runs per set-up ranged 

 between 15 and 20, and the area logged from one set-up covered 

 approximately 30 acres. From three to five logs were brought in 

 at one time and were loaded on skeleton cars by a long swing- 

 ing, end-control loading boom as shown in Fig. 52. 



During the last few years the cableway skidder has been in- 

 troduced with marked success on the Pacific Coast for handling 

 small and medium-sized timber.^ The machines are similar in 

 type and operation to those used in the c>^ress region, although 

 they are heavier and have a high speed for the return of the 

 cables. They operate from a headspar tree and log an area of 

 about forty acres at one set-up with a maximum working radius 

 of from 900 to 1000 feet. The crew is as follows: 



I skidding leverman i loading leverman 



I fireman i woodcutter 



I tong hooker 4 riggers 



I lielper 3 loaders 



I signal man i tong unhooker 



The logs are skidded directly to a logging spur where they are 

 loaded on cars by an auxiliary device similar to that described 

 on page 202. 



The average daily output ranges between 50,000 and 80,000 

 feet, for logs running between 500 and 1000 feet each. The daily 

 wage cost per crew is about $48. 



One manufacturer states that the cost of logs on the car is 

 about one-third less than for similar timber logged with yarding 

 engines. This is due to a reduction in the mileage of railroad 

 spurs required and to the elimination of sniping, barking and 

 road swamping. 



THE SNAKING SYSTEM 



This is a ground system in which the cables are taken to the 

 logs by animals. 



The essential features are an upright boiler with two, three
