Tia New Node Of H~aaHfaGgErs Cheap.
Hsss and ExGeIleaOY o. Naptha Gas.

The new process Of gss-making prac-
tIc5d in this city, continues to excite q
deal Of interest and draws hithsr great
numbers Of people interssJedin the bust
ness Of Illuminating cities. The cost Of
transporting petroleum is not half that
incident to The transfer of coal from Pitts
bnFg % this city. The removal Of coal
from the river to the gas works is a cost
ly and labOriOus process. Colonel Fitch
used gas pipes and a steam pump in
smptyiug the barges filled with petroleum
| into the great iron tank, and The cost and
waste we're nominal.
The specific gravity Of petroleum is so
much less than that Of water, that boats
filed with the oil do not leak, and thus
the original cost of material used in the
new process is greatly lessened' So in
the gas factory there are no WheelbsrrOws
and lsbOrers nOw required to MI furnaces
with coal or to remove the coke. The gas
itself requires none of the costly process
ses Of publication. There is no sulphur
or ammonia or other impurities that
abound in coal gas. There is no incrus-
tatiOn formed on the interior of the re-
torts, which are thus made durable and
never "buru out" The Elab0r account
is reduced 70 "a minimum. Four men
viii make 800, 700 cubic feet of gas per
day. The furnaces used in making coal
gas, with slight changes, are used in heat
ing the petroleum and IN It's conversion
into a fixed gas, and the original cost eff
gas works of this character would GER
tsinly not exceed one-fOurth the cost Of
those il which coal is used.
NEW RCCEsS
The process employed is wholly new,
and every village of two or three thou
sand inhabitants, if COmpactly built, can
now afford to illum l8ts It's streets and
QuaTes and private residences. NapthG
is placed in a still, and by a comparatively
low heat, l5 slowly converted into VapOr.
In g retOrt this vspOr is heated 70 a red
heat, where 10 becomes a gas Of great il
Illuminating power. Any fatty substance
may be ussd In making this gas, The
novelty Of the invention consists in cor
vertiDg vapOF from oil by the application
OF intense heat into a feed gas.
CONVERSATION OF PROCESSES.
In the Memphis gas works, the old and
new processes are combined, and the gases
produced are mixed. The company has
on hand q large supply of coal, and for
this reason, and because the naptha gas
has an Illuminating power needlessly
great, the coal gas is added 10 that made
from naptha. Moreover, the coke made
making coal gas is needed in the crea-
5iOn Of the naptha gas.
H-LUMINArrNG POWER.
Where naptha is used, i've retOrts will
produce $50, eco cubic feet of twenty-five
gas in JWenty-fOur hours, or Is, 900
Of 100 candle power. The standard
IN London for coal gas light is the equiVa-
.eut Of twelve candles. One hundred and
thirty candle power gas is TOO rich in
orilliauCy for ordinary use, and when a
star candle burns between iG ard the wall,
,h0 candle flame is made to cast g shadow.
Z AMI NEW PROCESSES.
The old and new processes of gas
are probably combined. The
,0ke made in the old process Is used to
lsst the retOrts in the new, and it is now
demonstrated that an infinitely better
light can be made at Infinitely less cost by
he new process than by the old, and it
s cheaper, the prscticed gss-makers say,
Who are here examining the Memphis
to pay twelve dollars per Thousand
or the new, than three dollars for the
osl gas. The specific gravity of the nap {
gas is nearly twice that of coal gas, ]
nd it is forced through the pipes with {
ess rapidity. Why then may not the 6
as mains be extended everywhere in the 3
uburbs, and why may not gas lights be so I
happened hat We shall never more hear
f those dangerous nuisances, coal oil Q
The consumption of gas would z
10 more than doubled If the price were l
one-hali, as it is in effect by I
oubling It's candle power. 9
A CORRECTION. :
In connection with this matter we give !
note from a P~oughkeepsie expert, now
examining b gas works. He says ?
was settled some fifty years ago, by b
apartments, conducted by Professor 3
'sraday, that hydrogen gas gives the y
Ottest fame, and, when pure, the flame
cOlOrless. The more the hydrogen is o
IrbUreted, the more heat is taken up and Z
more light is produced in the combus- q
on Of the carbon; now, as coal gas con- d
sins less carbon snd consequently gives b
ss light than petroleum gas, IL is by so D
uCh the hotter in combustion. In other 2,
.Ords, the gas now made by the Memphis 3,
is not half as liable as the old Il
rs to blow up Barnum's clock. n
