ANNUAL ADDRESS. XXXI. 
82,000 pounds per square inch and 25% elongation; this was 
made by the Bethlehem Steel Works and expanded from a solid 
ingot of compressed steel. The vertical shaft is made of open 
hearth steel. 
Niagara will ultimately become in my opinion a great industrial 
centre distributing the enormous energy derived from the Falls 
to the various works around it, and is a fine example of the 
utilization and control of one of the great sources of power in 
nature, for the use and convenience of man. 
The General Electric Company of America have designed and 
constructed a large number of long distance power transmission 
plants, one of the most important of which is that at Fulsom, on the 
American River, twenty miles above Sacramento ; a water power 
has been developed by the construction of a dam and canal, In 
the power house is installed four 1,200 H.P. horizontal turbines 
working under a head of fifty-five feet. Coupled to these wheels 
are four 750 K.W. three phase generators which run at a speed 
of 300 revolutions per minute, and furnish current at a pressure 
of 800 volts, and a periodicity of sixty cycles per second. The 
potential is raised to 11,000 volts by 250 K.W. transformers, 
located in the second story of the power house. There are two 
Complete pole lines carrying transmission lines of over 907 
efficiency from Fulsom to Sacramento, where the potential is 
reduced for distribution. In the sub-station there are three 300 
H.P. sychronous motors which drive a line of shafting to which 
is belted the generators for supplying the electric tramways in 
Sacramento, and for electric lighting. These generators are 475 | 
K.W. capacity and capable of supplying 309 lights. Being a 
three phase system there are three copper wires conveying the 
*urrent from Fulsom to Sacramento and at Sacramento a low 
Pressure network on the Edison three wire system is fed from 
the transformers to the sub-station feeder regulators giving 
complete control of the potential on the lines.
