inches in diameter at breast height. The logs averaged 550 feet 

 in volume. 



The engines were lOJ by 10^ inch compound-geared yarders, 

 equipped with loading drum. 



The average output per yarder per yarding day was 58,500 feet, 

 selling scale. The time on which this average is based includes the 

 time consumed in moving the yarders from one setting to another, 

 changing ends, raising gin poles, changing lines, etc., as well as the 

 time consumed in transporting logs from the stump to the landing. 



(3) The labor cost of transporting the logs from the stump to 

 the landing, including single and double hauling, at a camp along 

 the Columbia River in 1912, amounted to $0,746 per thousand feet. 

 It is not possible to state exactly the proportion of timber double 

 hauled. The amount, however, ranged from one-third to one-half 

 of the total output. 



This cost includes a part of the wages of the camp foreman, time- 

 keeper, and bookkeeper, and all the wages of the scaler. It does not 

 include the cost of moving the logging yarders from one setting to 

 another, loading, or the construction of pole roads and landings. 



The following crew was employed : 



Wages per day. 



Hook tender $5.00 to $6.00 



Head rigging slinger 3. 75 to 4. 25 



3 assistant rigging slingers 3. 00 to 3. 50 



Sniper 3. 00 to 3. 25 



Chaser 3. 00 to 3. 25 



Signalman 2. 50 



Engineer 3. 50 



At times it was necessarj^ to use four instead of three rigging 

 slingers, besides the head rigging slinger, also an extra chaser and 

 butt-chain-block man. Oil was burned in the machines at the land- 

 ings. A^Tien double hauling, the following additional men were em- 

 ployed : 



Wages per day. 



Engineer $3. 50 



Chaser 3.25 



Fireman 2. 75 



Wood buck 2. 50 



The average output delivered at the landing per yarding day 

 amounted to 70,000 feet. The fact that part of the timber was 

 double hauled should be taken into consideration when analyzing 

 this statement. While it is the aim in double hauling so to place 

 the logging engines that the swinging crew can handle the output of 

 the yarding crew without delaying them, such is not always the case. 

 There is no question that the yarding record would have been higher 

 if all the logs had been yarded direct to the landing.
