station industry OF the United States
in the census year of 1897 as com
pared with the census year of 1902.
and the growth during the interven-
ing fiye-year period, are shown in the
census bureaus special report, now
in press. on the second United States
census OF the central elecfTIc ng6t
aud power stations for the year 1907,
prepared by William Fl. Steuart. chief
statistican for manufacturers. in con
formity with the act of congress of
4, June = 1906, requiring the collection
Of such statistics at five-year periods.
The central electric stations are
defined in the report as those which,
exclusive of isolated electric plants,
furnish electrical energy for lighting
and heating: and power for manu-
featuring and mining. purposes. for
street railways and elevators. for
charging batteries. etc.
Two Glasses Of Stations.
Central stations are classed as
commercial" and municipal" the
former being those operated under
private ownership. whether of indi-
viduals. companies or corporations.
and the latter being those operated
by state. city. or other local govern
ments. except those operated espec-
tally fer institutions.
The central stations arc further
eIassed as purely electric central
stations. or those that do a strictly
electrical business. and Composite"
central stations. or those operated in
connection with some other industry.
It is stated that the majority Of the
cerNrl stations arc 81 the purely
electric" class
Il is noted in the report that the
figures given Tor the central stations
do not represent the entire produc-
ton OF electrical energy. To arrive
at the aggregate it would be neces-
sary. II is stated, to consider only
the electric railways, telephone and
telegraph lines. electric police-patrol
and fire alarm systems. and the $50
lated electric plants.
In the first chapter Of the report.
which is a general discussion Of the
subject st is stated that the ten
dency to sell electricity for general
commercial use is constantly increas-
ing among electric railway compa
mics.
In } - there was 251 railway com
Ipanies which furnished electricity for
Hight. power. and other purposes.
These companies report an aggre-
gate income Of S7.7O3,574 from the
sale Of current. In 1907 there were
$50 railway companies in this class
and the income from the sale Of cur
trent amounted to S2O.093. 3O2.
Annual Output.
In 1902 the annual output OF all
electric stations and electric railways
amounted TO 4.76s. 535.5I2 kilowat,
hours In 1907 the output Of the two
classes OF stations was 10,621 .4OG. S37
b kilowatt hours. the increase in that
year as compared with 1902 being s..
S52 ST1.325 kilowatt hours. or 1921
p per cent. IN 1902 the output by cleo
trio railways formed 47.4 per cent of
the total but by 1907 the proportion
for such railways had fallen to 449
per cent.
Consultations Of the two branches
Of the industry and the growing ten
idency Of the railway companies to
sell electricity for commercial pur.
poses are referred to in the report
, (which futher states that the seperate
statistics of the central stations are
/ therefore. not representative Of all
the electrical energy sold for general
commercial purposes. It is observed
that during the FIVE years ending
with 1907 the central stations in
8 creased more rapidly than the cleo
trio railways
I Great Increase in Plants.
The number of commercial ane
; municipal plants increased from 362t
: in 1902 TO 4714 in 1907. the increass
amounting to 1894. or 30.2 per cent
