A contract for 1000 hip. has been closed
with them. Besides these concerns,
there are a number of other smaller
manufacturers taking from so to rs hip.
each.
The second ~, 100 volt line extends d.
rectly across the river to New Hamp-
shlre and on to Keene, a distance of
about 20 miles. This line is not yet fully
complete but is being pushed forward
rapidly and will be in operation before
the end of the summer. A contract has
been made with the Keene Gas and
Electric company for 500 XIV. with priv
llege to increase this to 1900 XIV. as re-
CURED. This line is being built by the
heene company who will also operate
and maintain It.
The two &C, 900 volt lines extend dag
onally across the river from the roof of
the power house-a distance of 1920 feet
and continue in a southeasterly direc-
tlon across a corner of the state of New
Hampshire on into Massachusetts, PASS
ing through the cities and towns of
iilnsdale, Mortified, Warwick, Royals
ton, Winchendon, Gardner, F%itchburg,
Leominster, Sterling, Clinton, West
Boylston, Marlboro and into Worcester,
a distance of 66 miles. The conductors
are made up of No. 2 BIS copper cable
carried on 80 Id. insulators supported on
steel overs of the two circuit type built
by the American Bridge company. With

power house and a span of 1910 feet
across the Wachusett reservoir in Clin-
ton, the average spacing of the towers is
4lO rect. There are a total of SS5 towers
on the main line exclusive of SO more on
a branch line running from the Fitch
burg switch tower to the substation.
switch towers with suitable disconnect-
ing switches are located about every ten
miles, which brings them at Warwick.
Koyalston, Gardner, Fitchburg and Gin
ton. At each of these points patrolmen
are stationed nearby who can quickly
sectionalize the lines and 'localize the
defect in case of trouble. A private
telephone line made up of No. 4 copper
clad steel wire extends the full distance
or the transmission line and is tapped
INTO every substation. This is also sec
tionalized at every switch tower. At
every point on the system where a tele-
phone instrument is installed, protective
apparatus in the shape of an electrolytic
arrester and drainage coil is also located.
The service of the telephone system has
been very satisfactory, very few cases
of serious trouble having been expert
enced. A No. 5 copper clad steel ground
wire supported on a central mast is car
ried the full length of the transmission
line and grounded at every tower. In
terruptions from lightning have been
very scarce.
The equipment of the various substa-
'iOhS anu lue amount OF power supplied
to the various manufacturing concerns is
here noted. At the Gardner switch tow
er the main line is tapped and the
branch carried on wooden poles to the
substation of the Gardner Electric COM
pany. The Transformer capacity of the
station is 1900 XIV. At the Fitchburg
station are installed seven 1900 XIV.
transformers. The customers there are
the F1tchburg Gas q Electric company
Q0o0 h.p.), three mills of the Parkhill
Mfg. company 1920 h.p), eight mills of
the Crocker- Burbank company (22OO h.
p), De Jonge Paper company 600 h.p),
and the Falulah Paper company 600
h.p.). Mr.. Mahoney says: 1T is of in
terest to note here that all the paper
used in printing the Saturday Evening
Post and Ladies Home journal is manu-
featured in the Crocker- Burbank mills"
The Clinton substation is equipped with
four 1900 XIV. transformers and power is
supplied to the Lancaster Mills 600 h.p.)
and the Marlboro Electric company $500
h.p.), the latter being used in Marlboro,
Westboro, Northboro, Berlin, Southboro
and Shrewsbury, The Worcester substa-
ton is located in Greendale, a subur of
Worcester, where there are six 1900 XIV.
transformers. Four overhead lines leave
this substation. one supplies the Os-
good Bradley Car company, the Morgan
Spring company, the Norton Grinding
company and the Worcester Pressed

for street Lighting and miscellaneous
purposes. The two remaining circuits
run to the city of Worcester to a termin-
al house on Brookfield street. From this
terminal house two cables are carried
underground half a mile to the north
work of the American Steel d Wire
company, and from the north works a
cable extends three miles to the south
works of the company, at Quinsigamond.)
In all the company's substations the

which are paralleled Will K-10 oil
switches, these switches being equipped
in each case with reverse current relays.
Should a short circuit occur on either line,
this paralleling switch would ton
cally cut that line out and leave the sta
ton operating on the other line. Hereto
fore different substations We're run from
different lines, the two lines being paral-
leled at the power house only. AS a con-
sequence it was found that during certain
load conditions it was almost impossible
to meet the voltage requirements of Gus
toners operating on different lines, and
whenever a short circuit occurred on
either line, all customers operating from
that line We're interrupted until the
power was restored; or else they were
transferred to the other circuit. The
paralleling of the lines In all the stations
has greatly improved the regulation of
the system and reduced the danger of in
terruption to a minimum
All incoming and outgoing lines are
protected by electrolytic arresters, and
at the transformer station of each GUS
toner arresters of the same type are
installed. These are charged twice daily
at stated periods.
Each substation is equipped with a
storage battery for operating the oil
switches. All transformers are of the
water-cooled type. and for the sake of
simplicity all the substations were de-
signed as nearly alike as possible. Fire
proof construction was followed through
out.
The company makes two classes of con-
ira known as primary and secondary.
Under the terms of a primary contract,
the company guarantees to deliver the
amount of power contracted for, while
under those of a secondary contract, the
right is reserved to cut off the supply of
energy upon reasonable notice. The
price of secondary power is, Of course,
less than that of primary, and in making
primary contracts the company is keep
ing well within the low water capacity
of the Connecticut river.
