LOGGING IN THE DOUGLAS FIR REGION.

The freight rate from Chicago to Pacific coast terminal points is 

 $11 per ton. In estimating the cost of the rails to be used in a given 

 case, one should add the cost of transporting the rails from the 

 terminal point to the camp. 



In 1914, first-class relaying rails at Pacific coast terminal points 

 were worth about as follows: 



45 pounds per yard and down, $35 per ton. 

 50 pounds per yard and up, $36 per ton. 



Second-class inspected relaying rails were worth about as fol- 

 lows : 



45 pounds per yard and down, $29 per ton. 

 50 pounds per yard and up, $30 per ton. 



It is customary to figure the life of steel rails at 20 years. This is, 

 no doubt, about right for the rails used in main-line logging roads. 

 Possibly it is too high for rails used on spurs, where the grades and 

 curvature are heavy, the roadbed is relatively poorer, and the steel 

 is taken up and relaid often. A life of 15 years, with a scrap value 

 of 20 per cent of the initial cost, is thought to be a better basis for 

 estimating the depreciation on rails so used. 



Angle hars. — Either angle bars or fishplates are used to strengthen 

 and brace the rails at the joint. The usual method is by means of 

 angle bars. They are bolted on each side of the joint with two bolts 

 in each rail head. 



The weights of angle bars for four typical weights of rails are as 

 follows :

The cost of angle bars f. o. b. Pacific coast terminal points in 1916 

 was approximately $2.05 per hundredweight. The cost of angle bars 

 per mile for four typical rails is as follows :
