About Gas.
BURNERS. There is no part connected
with the consumption of gas whereby the best
results are obtained in the quality OF light and
economy of gas Of more Importance than the
burners. 1t would be difficult to convince the
majority OF gas consumers. who have not given
the subject attention. how remarkably the light
from gas is reduced by those improperly con-
structed, or where the pressure or the flames
are unsuitaby adjusted Owing TO these cir
cumstances, the amount of gas consumed is
disproportionate to the light obtained, and the
account Of the consumer is much increased. ln
TACT, there is no exaggeration in stating that a
large proportion of the consumers, through
their own mismanagement pay twice as much
AZ there is any occasion tor, considering the
amount OF light obtained, all Of which could be
,uvcd by using proper burners, and 4 correct
adjustment and control of The pressure.
1.-The important requisites ior good burners
are, that Oritices where the gas issues should
lie perfectly regular in size, to permit it to issue
with very low pressure end these conditions
ghould be adhered to, whatever the kind the
burner may be, whether the argand, bat'wag,
lishtail, or single jet. II the oritces are too
small, high pressure is required TO eXpel the
gas, aud the light is diminished Just in pro
portion to the increased pressure. 10 such bur-
ners the flame will have . blush tnge, and the
lower part will be Of a deep color, giving but
little light in proportion to tho gas consumed.
As an example, an argand OF fifteen holes,
passing five feet of gas at one tenth pressure,
Yielding light Of twelve candles, will, il the
orifices arc reduced to bass the same amount
Of gas per hour at fige-tcnths pressure, only
i've the light OF six candles, loss OF thirty per
cent. Hence, we sec that the light to DC ob-
tanned i.om given quantity and quality OF
r,s IS entirely dependent on the burner employ
cd. This demonstrates the necessity OF having
propcr burners, and shows clearly how, by neg
iigcncc on this point, the consumer may Ind
his gas bills increase in what appears to him
very mysterious manner.
SIZE OF FLAME-lt is mistake to sup
pose that the amount of light obtained will be
in proportion to the quantity OF gas issuing
from burner. There is particular point IN
,be consumption of any class of burners where
the maximum of light is derived, and any
deviation from this entails loss. AS an exam
p.c: if on argand burner consumes five feet per
hour giving the light Of twelve candles be re-
,luced 50 that only three fourths OF that quantl-
v;s burned. then the light. instead oil being
cnual 10 nine candles, the theoretical proper
,ion. will be six candles only. being positive
ioss Of thirty six per cent. This reduction may
be continued with even greater proportonate
loss. -
I. five feet bat-wng or fish tail burner will
give maximum light in proportion to the gas
consumed, compared with any less sized burn-
er, and it will be found in practice the larger
sized burners are the most economlcll, the
large sizes giving as high as 2O0 to 3O9 per
cent. advantage in light, as compared with
the smallest sizes. As an example, bat-wlng
burner, consuming two feet per hour, gives
49, l;,,bt ~ nd
while burner consuming seven-and q halt teet
per hour gives the light OF twenty two candles,
the pressure being uniformly four tenths OF
an inch.
"It is more economical to have one good,
large gaslight than several smaller on9S.
"GIoBEs, GLASSES, &c.-Although chin.
peys arc essential to argand burners and
globes also in many places where fin tail burn.
crs arc used. and the ornamental effect is
pleasant, still they are detrimental to the
diffusion Of the light Of gas. A clean glass
g'obc obstrucis about twelve per cent. clean
globe, engraved with flowers, about twenty four
per cent; globe ground all over about forty
per cent an opal globe, about sixty per cent.
Hence is apparent the folly OF using eaoorateiy
engraved and ground globes or shades. whe n

the lower part should be left clear for the free
