This plan of power development further includes the construc- 

 tion of a storage of 1,250,000,000 cubic feet, which is estimated to 

 cost $148,000, making a total for the whole development of 

 $1,038,450. With these figures the final cost per net horsepower 

 becomes $52.22. The estimates leading to this result include cost 

 of land to be flooded, masonry of dams and head works, turbine 

 water wheels, flumes and head feeders, tail raceways, waste gates, 

 power stations, racks, engineering and superintendence, etc. So 

 far as the actual power developments are concerned, the work can 

 probably be constructed for the estimates, but the cost of the 

 storage is, in the writer's opinion, somewhat too low. The total 

 number of dams which it is proposed to build is stated at 40, thus 

 giving an average of only $3700 per dam. This sum would only 

 build timber dams of the most temporary character. The proper 

 operation and repairs of this number of dlams, scattered over an 

 area of 200 square miles, would entail in the end an annual 

 expense of $30,000, which is the annual interest at 5 per cent on 

 $600,000. To obtain the real capitalized cost we need then to add 

 $600,000, which gives an amended total of $1,638,450, whence the
