motive and tender. The estimated hauling capacity of given weights 

 and types can usiiall}" be found in catalogues of manufactures. In 

 Table 32 the estimated hauling capacity of rod and geared locomo- 

 tives is given. 



The approximate cost in 1914 of rod and geared locomotives at 

 Pacific coast terminal points was as follows :

1 Hauling capacity given is calculated on an assumed rolling friction of 8 pounds per ton. 



These prices do not include oil-burning equipment, which can be 

 installed for from $400 to $500 per boiler. For shipment to the 

 Pacific coast all locomotives under 42 tons in weight are loaded on 

 flat cars, and the freight rate is $1.50 per hundredweight. Larger 

 locomotives are shipped on their own trucks at a rate of $0.88 per 

 hundredweight, plus $200 for a messenger to accompany the engine. 

 For 32-ton to 80-ton locomotives the shipping weight is from 5 to 

 8 tons less than the working weight. 



It is not possible to state the maintenance cost of locomotives, 

 because it depends on so many factors. One logging superintendent 

 is of the opinion that it ranges between $600 and $1,000 per year. 

 He stated that the upkeep of three locomotives, 18, 36, and 42 ton, 

 during the last year of operation amounted to $2,425, and that the 

 upkeep of a 60-ton engine, which averaged 60 miles per operating
