Power house 145 feet by 45 feet, containing four 1,500 Kw. 
generating units, each having a twin Pelton wheel. The alternators 
by Bruce Peebles, give 3 phase current at 10,000 volts 50 cycles 
when running at 500 revolutions. 
Switch board by Ferranti with oil switches, feeder panels at 
back of generator panels and a room between. Lightning arresters 
of horn and water jet types. 
Transmission lines in three directions—to Dinorwic, Pen-y- 
Orsedd, Oakeley quarry centres—of copper wires on wooden poles 
set 40 to the mile; some are lattice poles. 
The Oakeley quarries at Blacnan Festiniog employ 2,000 men, 
and the installation consists of two substations containing 500 Kw 
oil cooled transformers, stepping down to 520 volts, supplying 
current to 37 motors aggregating 1900 HP. 
Oonsidering that Australia is such a large continent it is 
singularly lacking in natural water power, yet particulars 
of two successful plants already at work, namely at Laun- 
ceston and Hillgrove are given in the table. Barron Falls 
is one of the largest water powers not yet harnessed, 
and according to Mr. Corin this Fall will develop 3,500 
electrical horse power at the generator terminals for all 
the year with a minimum of 50 feet per second on a head 
of 818 feet. From records taken weekly from June 1899 
to January 1901 and thus including the exceptional drought 
year of 1900, the flow varied from 684 to 41 cube feet per 
second, and only for three months of the above period was 
it below 100 cube feet per second. With water storage, 
therefore, Barron Falls should easily give 5,000 HP. and 
possibly nearly double that. 
It will be noticed that the power depends mainly on the 
high head, and it is just possible that if search were made, 
several insignificant looking falls would be found which 
could be made to give a head of over 1,000 feet at the 
power house with only a moderate length of pipe. As will
