P:ndicular cylinders, with an air tight
cover ench one contains tour cast iron
perforated plates, placed one above
the other, about six inches apart.
These plates are covered to about the
depth OF Two inches with the hydrate OF
line e-throuxh this lime the gas passes
after being introduced into the purityers
from the central seal o. valve Alter
passing the lime the gas returns TO the
centre valve, when is passes 10 the
station metre.
The Station Metre--,s constructed on
the same principle IA the small meuta
in the stores mud shops-and is made
Of cast on. being some six feet IT,
diameter and six feet in length, ana il
capable o; Registering some 80 10
loO,0 900 cubic feet Of gas per day.
From the metre the gas passes to the
inlet valve located ~ the metre room,
from thence i passes into the gasome'er.
the receptacle lor H. IL then passes
through the outlet valve in the metre
room into the governor to be regulated,
The Gdsoneier This is a large
cylindrical inverted vessel, built upon
the latest and most improved plan, call
ed the Telegraph Gasomeier--it being
the only one hunt Of the kind west q"
southwest Of New York, except the oGe
at Buffalo, and contains some 1000 o
cubic lcet OF gas lit being built in TWO
sections, the upper section raising or
drawing out like the telescope (ahen
the gas is passing into iD and vice
versa, closing together when The gae is
passing Quilt Is placed in large ;ann
or cistern filled with water in this the
gasomcrer sits like a tumber hottom.up
IN basin OF watcr-the gas enters from
beneath by II pipe from the inlet valve.
the mouth Of the pipe being placed so
high inside Of the gasomeier as 10 be
above the water, the use oi the waer is
to prevent the gas from escaping from
beneath the gasometsr. AS the gas
enters, It ior;es the gasometeI TO rse,
The weight Of which furnishes The pres
sure necessary TO force the gas IhrouL "a
the city, and out of the lunirar,es III.
side OF the gasotneter is another pipe,
the mouth of which is also placed a
hove the surface oi The water, by walch
the gas is let Oh TO the city by means Of
the ou,le, valve into the governor. The
governor consist Oi u cast iron cylinder
or tank TWO lcei six inches in dlau cter
ana three l.rt high, III which Il small
gasomcier plays, having an in'cl and
an outlet pipe attached: TO tie outlet
pipe Is an open huc in which II cone
works lor the purpose OF regulating the
pres ure on the burners throughout the
city. For instance, ~ the iorepat OF
tie cvening there ara 1900 burners ia
OF sration-ihe cone then drops with
lie snalI ga.ometcr soas 10 give The
required PRESSURE at 8 O'Clock one
hali Of those burners ~ e shut oil there
by increasing the prcs.urr, the small
gnsoneters and cone immediately
ralsng and closes up II. nporuon oil the
aperture. and thus gives The required
and proper pressure on the burtrrs.--
The gas in passing through the wash
crs, AS previously described, is depriv-
cd OF a large portion oi suiphuraticd
hydrogen and ammonia-thence through
the Inns IN the purify ers; the remain
der of sulphuar,,ed hydrogen, ammona,
carb3nlc oxydes, carbonic acid, and
other impure gases, arc taken up by
the lime, alter which il IL ready for use.
The gas IN passing from the reto'ts
into the gasomcters has to trave' nearly
l.U0O feet oi ipe.
Statisfirs.-The number OF ieet of
pipe lad in the city up TO this time is
az follows:
