moved and electric driven units or
twice the capacity installed without
any changes in building other than
foundation, at the same time reduc-
ing station expenses for labor, sup
plies, fuel etc, and losses due TO con-
densation In pipe lines, heat radia-
ton and waste of fuel due to faulty
firing, so that in frone one to two
years the cost of the electric driven
installation Is returned in expenses
saved. That this can be done Is ex-
planned by the simple fact that in cleo
trio station practice only the most eff
ficient boilers, engines and generators
are used. The wastes in small steam
plants which are greater than in the
large plants become such an item OIL
cost as to more than warrant the pur-
chase of power from the larger plant,
while economy. f1exibility and con-
venience in handling electric service
overcome many of the serious features
of steam generation in pumping In
creased requirements in pumping due
to serious fires in the districts, or de-
creases in pressure from any cause
are provided for automatically.
AS a striking instance of the import
ance of electrically driven pump in
| stallations, mention need only be made
| of the very complete high pressure
| fire service system in the business dis
trict of New York city.
There the electric supply is required
| to furnish the entire demand for pow
er and in the many trying fires or
docks and in high buildings the sys-
| tenn always has been ready for tbs
! most severe tests and has never failed
No attention other than the one mar
| on duty in the plant is required to tak'
care of the system in fact. one engin
| eer or electrician can handle the en-
| tire system of a large city such a
Hammond during the usual working
| hours, as compared with engineers. fire
men. coal passers, gate tenders, etc
for the steam driven system. Anothe
| advantage is that centrifugal punt
| gives a continuous discharge or stream
or water without the use OF air cham
| bers, and there is no noise due I
shock, pulsation or vibration in tn
| pipe and often the bursting of pip
lines due to water hammer.
In many cities, particularly in tn
vicinity Of Chicago, electric pump
have ben installed replacing previou
steam driven units or used in in

outlying districts. Oak Park. La
Grange. DeKalb. Blue Island, Par
Ridge, Chicago Heights may be men

about one-half the equivalent steai

approximately to two-fifths.
