driving machine tools by means
of betting and sllafting has been
eliminated on account OF the greater
economy of power space, and con-
vcnence of handling work By means of
cranes and hosts.
LIGHT AND POWER.
Owing to the rapid growth OF the
company's electric light and power
service and the Improvement in its
schedules and extension of Its street
railway lines. n considerable increase
In Its electric generating capacity has
been required, and much rcarrange-
mcnt Of its transmission and distribu-
tion lines.
When Mr. Hartman took over the
system he promised to give Salt Lake
City public utility service second to
none in the country, and much Of the
money expended during the current
year has had as Its object the improve
ment in the quality of the company's
service. The extension of the street
railway lines to MiGvale and Sandy
required the erection Of a sub-stntion
to convert the alternating current as
delivered from the generating stations
to direct current for use on the street
car lines. Until this sub station Is
completed. which will be soon after Jan.

During the latter part of June an
nouncement was made from the office
of President Bancroft that contracts
had been let and construction work
started on mammoth new steam
plant of 1000 horsepower capacity.
and the money necessary to construct
this plant was being spent for the sole
purpose of furnishing a continuous and
uninterrupted supply of electric light,
power. and street railway service in
this city. The plant was designed as
an emergency plant and all arrange
mcnts are made with the view OF get
ting the plant running and in service

DEVILS GATE POWER PLANT.
The 1000 horsepower hydro-elcctric
plant which has been in the course of
erection for the past two years at
DEVILS Gate in the Weber canyon.
was completed and put in operation
early in September. This plant Is as
complete and efficient as modern en-
cheering skill and money can make

milo and half above the plant, and

down the canyon to the plant. which Is
located just above the intake to tho
Davis and Weber county canal. The
intake dam and reservoir has sufficient
capacity for storing enough water to
run the plant at its full output for
five hours. The generating equipment
consists of single unit which has Il
capacity of $500 iilowatts. 1t is direct
ly connected to and driven bye 1000

The completion of this plant gives the
company II total generating capacity OF
22000 horsepower. which is ample for
carrying the heavy demands which will
be made upon it during the present
winter.
NEW TRANSMISSION LINE.
In addition TO the power plant. the
company is now erecting II steel tower
transmission line from salt Lake city TO
Ogden with branch line four and Il
half miles III length 10 connect with the
Devils Gate plant, This latter branch
is now completed and in operation and
all OF the materia! for the entire line is
on the ground, and the work OF erecting
will be proceeded with as speedily as
possible. 1t has been demonstrated
that steel tower transmission lines
arc far more reliable than the old style
wooden pole lines formerly used and
that Interruptions to the service due to
failures of the transmission lines may
be reduced to n minimum with this form
OF construction. Although steel towers
are vastly more expensive than wooden
poles their increased reliability and
longer life fully Justify the additional
investment. The towers will be set 600
feet apart, with not less than II six-foot
concrete base Tho tower line VIII carry
Il double circuit Of tarec wires each. so
that in case one circuit Is damaged,
It can be cut out and repaired while
the other continues to carry the load
A steel messenger cable is suspended
above each circuit and grounded at each
tower as Il protection against lightning
flash, which Is only Il discharge of cleo
tricity between the clouds and earth Is
caught by this messenger wire and
transmitted safely to the earth without
doing any damage whatever to the line.
Az lightning has been one OF the prin-
cipal causes of interruption to the COM
pany's service It will be seen that this
Improvement Is one OF tho most impor-
tant which the company could have
made.
