To give an idea of the value of the power which is being generated by these 

 plants, it may be stated that to produce 171,530 kilowatts from coal would require 

 2,676,000 tons, which at the average price of $4.00, which would apply at the points 

 where the power is used, would amount to $10,704,000. 



When it is considered that the value of this coal is, by means of water power, 

 being saved each year from future generations, and that during the next ten years 

 this saving will, in all probability, be increased seven or eight times, it is not 

 difficult to understand that true conservation consists in encouraging the rapid 

 development of water power, which unless developed and utilized becomes lost 

 for all time. 



Transmission Lines. 



The transmission system of the company inter-connects all of its power develop- 

 ments, with the exception of the Thompson Falls, and covers an area extending 260 

 miles from east to west and 300 miles from north to south. The various lines are
