LOGGING IN THE DOUGLAS FIR REGION.

day, amounted to $1,121 during this year. Another logging super- 

 intendent estimated the maintenance cost per year of locomotives as 

 $600 for rod and $1,100 for geared. 



The following data, based on four years' time, were furnished by 

 a logging superintendent. The information has to do with four 

 geared locomotives, one 60-ton and three 50-ton.

If locomotives have the proper kind of treatment, the maintenance 

 cost per year will probably range from $400 to $700 for geared loco- 

 motives and from $300 to $400 for rod locomotives. 



The service demanded of locomotives on logging railroads is 

 usually severe, the result being a relatively short life. For the pur- 

 pose of a timber appraisal, the life of rod locomotives used on a main- 

 line logging railroad may be placed at 20 years, the life of geared 

 locomotives at 15 years. If the work to be done by the latter tjj)G is 

 particularly trying, 12 years should be used. 



Cars. — Three types of log cars are used in the region ; namely, flat 

 cars, skeleton cars, and separate trucks. 



Flat cars are not used to any extent except where the logs are 

 hauled over a common-carrier railroad, in which event the cars are 

 not owned by the logging company. Of course, all logging com- 

 panies have three or more for use in connection with construction 

 work, etc. There are a number of makes and sizes on the market. 

 The standard low logging flat car, built in the region, is 41 feet long 

 and accommodates 42-foot logs. It has a capacity of 80,000 pounds, 

 weighs 26,700 pounds, and costs about $850 f. o. b. Seattle. When 

 equipped with very satisfactory patent bunks and chocks it costs 

 about $925. 



The skeleton car consists of two pair of four-wheel trucks joined 

 together by heavy timbers, and is very satisfactorj?' where it is 

 desirable to use air brakes. One make, which is used as much as any, 

 costs about $750 f. o. b. Seattle. This price includes air equipment, 

 also patent bunks and chocks and automatic couplers. The car is 

 built in lengths up to 56 feet over all, has a capacity of 80,000 pounds, 

 and weighs about 19,000 pounds.
