Figuring on a three-fourths load, which would be possible 

 in a large plant, the cost of power would be about 1.28 cents 

 per kilowatt per hour. 



Since it wiU be some time before more than a very few of the 

 mills exceed this power consumption, the power problem beyond 

 this point must include the centralization of the power plants 

 and the distribution of the power electrically to the various mills 

 and quarries. Mr. H. St. Clair Putnam in his address before the 

 conference of governors of the United States held at Washington 

 in May, 1908 {Report of the Conference of Governors, p. 293), 

 said : 



Electrical transmission of power is the new art which now is resulting in 

 another and radical change in methods of utilizing our power resources, 

 permitting, as it does, development whether by water power or by steam 

 at points most convenient and economical, and transmission to the consumer 

 in form adapted to great variety and convenience of use. This new develop- 

 ment in applied science calls for reappraisement of the sources from which 

 our power is derived. The size of the power plant is no longer limited to the 

 requirements of the individual user, but the power for entire communities 

 can be supplied from a single station. 



There has been much talk of centralizing the power plant to 

 the extent of having a single plant supply power to the several 

 quarries and mills which are in the same neighborhood, and 

 in many cases this could be carried out economically. The cost 

 of a 1,000 horse-power steam plant with a compound engine 

 and water-tube boilers would be about as follows: 



Three 250 horse-power B. and W. water-tube boilers $10,550.00
