motion to electro-magnetic engines, to ignite the carbon points of 1877 

 electric lamps, or to effect the separation of metals from their iemen8 

 combinations. A copper rod 3 inches in diameter would be 

 capable of transmitting 1 ,000 horse-power a distance of say thirty 

 miles, an amount sufficient to supply one-quarter of a million 

 candle power which would suffice to illuminate a moderately 

 sized town.

The object of this paper, which was read at the annual convention 

 June 10, 1884, is "to show what has been done or what may be done 

 toward the utilization of Niagara for electrical purposes." Some account 

 of the power already developed is given, and the future development, 

 especially with its application to electricity at a distance, is studied and 

 forecast. 



Enough, however, has been said to show that the power of 

 Niagara can be transmitted to a distance of 25 miles, with a 

 great saving over the power of steam, and that with improvements 

 in storage-batteries and electro-motors, this distance can be 

 increased, with economy, to 100 or 150 miles. With further 

 improvements in dynamos and insulating material to permit the 

 use of currents of higher intensity, such as may be confidently 

 looked for, the economical distance may be still further increased,
