In the United States More Than
Doubles in Five Years as
Report Shows.

WASHINGTON. D. G.. Feb. 49,.
The quinquennial report on central
light, and power stations and street
and electric railways, relating to the
calendar year. 1912, will soon soon
be given out by Director William j.
Harris. Of the Bureau Of the Census,
Department of Commerce. The re-
port, which was prepared. under the
supervision Of William NJ. Steuart,
chief statistician for manu- cturers.
Will show that the output for light
and power stations increased from
{, 1862 900 .009 leilowatt hours I'd 1907
to nearly 1t,,59 80 0. 600 in: s12,
practically doubling, while the num-
Der of revenue passengers carried by
the street and electric railways in
creased during the same time from
I7.441, 100000 to 9,546, 100000, OF
by more than one-fourth.
The census bureau has already ii.
sued a preliminary report or bulletin
giving the more important statistics
gathered at the electrical industries
census Of 1912. but the detailed re-
port contains many features Of inter-
est not included In the preliminary
announcement.
Growth Of Light and Power.
Perhaps the most striking, feature
Of the report Is found in the figures
1T gives with reference to the growth
of the central electric station indus
TRY. The total number Of such sta
tons for which reports were obtain
ed in 1912 was 1921. OF which 8, 659
were commercial and 562 were mti-
nicipal. The term station" however,
in some cases represents two or more
plants operated under the same own
Iership. The total output of the COM
lmercial and municipal stations, taken,
together, increased from over 2,507.
900, 900 kilowatt hours in 1902 10
more than {, $50 ,000, 900 in 1919.
the percentage Of increase being $50
for tho decade and 96.7 for the peril

Commercial and Municipal Stations.
| That the municipal stations are.
on the average. much smaller in size
than the commercial stations is made
evident by a comparison Of the pro-
portions which their numbers and
their output, respectively, form OF
the total number and total output.
In 1912 the commercial and the I1u.
Anicipal stations reported, respective
lily, 70.1 per cent and 29.9 per cen,
lof the total number Of stations.
while the output Of the two classes.
respectively, formed 95.3 per cent
and 4. per cent of the total output,
i The difference in average size, how
lever, is somewhat less than these fig
lures indicate, since in many cases
A two or more commercial plants oper-
ated under the same ownership were
reported as d single station, while
this practice did not prevail III the
case Of the municipal stations. OF
