about gas, which, II you avail yourself oil,
will save you good deal OF money.
now TO BURN Gas.
You would naturally suppose that the
light obtained from gas.burner would
be indirect proportion 10 the amount Of
gas hurned-that Is, II an foot burner
should give the light OF 10 candles, 4
foot burner would give the light Of s can.
dies. This Is not 80. Gas chemists all
say-and saw the experiment tried yes.
terdsy-that the light Is not in proportion
10 the amount Of gas consumed. AS an
example: II flame consumed 8 feet per
hour, giving the light Of 10 candles-and
this be- reduced to IL feet Il OF 81 then, In
stead Of the light being equal TO IL can
dies, the theoretical proportion, 1t will
only equal 8 candles, causing a loss oil 80
per cent. And If the flame be reduced to
consume 4 feet, instead Of the light being
equal TO 8 candles "a proportionale amount
OF light, 1t will only be equal TO 81 can
dies, being q loss Of 90 per cent. Lastly,
II the flame be reduced to It feet per
hour, Ia small blue flame will BIO seen,
which will not give any available light.
Then the cost Of light from gas Is very
much decreased as you decrease the size
Of the jets. 80, II you have 4 2t.teet gas
Jets in your room, making o light equal to
| 10 candles, throw tue little jets into one
making 10.loot burner, and you will
get light equal 10 about 29 candles. (See
page Al, Gas Consumers Guide, London |;
F. & E. N spon)
1t will, therefore, save you much money
II you have one good gas Jet In place o. q
number OF small Ones-and any gas'honse
chemist will tell you the same thing.
Mr. William Richards, an eminent Eng.
lish writer on gas, furnishes this table IL
Illustrating the true proportion between the
amount Of light aud the amount Of gas
burned In an ordinary flshtall burner
and the same is endorsed by the engineers
in the New York gas houses:
Burner cons'lng ~ Il, gives light oil candle;
Burner cons Ing az Il. glVes light OF 21 candles.
Burner consInH AZ #. gives light Of 10 candles.
BaTner cons ing 5 Il gives Light Of l2H candles.
Burner cons'lDg7it gives Light Of IS candles.
Mr.. Richards says theatre lighted
with 200 small jets, consuming $50 feet
per hour, and giving the light Of 200 can
dies, can be lighted as well with II seven.
foot burners, which would use only n
feet Of gas per hour-S saving Of 1913 feet,
II you want q small light have big
burner and turn 1t down, for gas coming
through q big orifce slowly gives more
light than when forced through a small
ofifcc.
How else do we lose light and gas2
By shades and globes. Mr. King, oil
Liverpool, and Mr.. Wood, Of Hastings,
England, say that light Is diminished by
being passed through globes as follows:
Light through pain glass globe. III per cent
Light through globe engraved with
Light Through ground globe, Trans. >. ,.
parent iR,GPSS ,onnJ olob: per e esns
Light through painted opal globe. "a per cent.
When you use globes let the upper half
be ground, obscured, &c, and let the
lower half be transparent and you will
loose only Is per cent. Opal globes are
beautiful but they are ieariully expensive
destroying 90 per cent Of the light.
TO MEASURE LIGHT.
They have o beautiful machine 10
measure light, but 1t is too complicated 10
describe without cuts. You can measure
light relatively yourself. Take o gas Jet
at one end oil your table, and o wax can
die at the other. A leadpencil, when
near. either the gas or the candle will
make shadow. Move, ii and you will
find place where it will make no shad-
ow either way. The light comes with
equal intensity from both ways. This
will show you the reldtire intensity OF the
light from the candle and the gas. Light,
OF course, like heat and sound, radiating
from a common centre, diminishOs as the
square Of the distance.
aAsMETRRs.
Gas metres almost always tell the truth.
The index has three faces like watch
faces. They are labelled hundreds"
items" and 'Iunits," but each face repre-.
sents units, tens, and hundreds Of hundred
feet of gas consumed. To illustrate, il the
hand on the "uni" dial stands at 6, the
hand on tho items" at 8, and the hand on
the Hundreds" =. at 4, you should read 1t
As, 600 cubic feet. You can look at the
dial at any time for your own amusement.
II you mistrust your gas In leaking any
time, turn off every burner In the house,
and see il the dial marked "units" still
revolves. The hands on the dial move
very fast, and you can soon tell il gas is
escaping without sending TO the gas.
houses.
GAS MIsTAKEa
A gentleman on Thirty.fourth street
went of TO Saratoga last summer and
closed his house. When he came back
the gas.man presented heavy account
for gas burned while he was gone.
"But, It's q mistake, sir We were all
gone to Saratoga. We didn't need any
gas" expostulated my friend.
"Can't help 1t, sir; the meter can't lie,"
put in'the gas company.
The gentleman was such good man
that finally the engineer went to his house
and questioned his wife. "Well," she
said, "how silly! Now ! recollect that,
Just as we were leaving, ! had forgotten the
keys, which were lett in the drawing.
room, and, as lighted the gas to find
them-and 1t was burning when We came
back!"
A gentleman went to Europe and left a
four. foot burner burning In the wine room
for eight months. Multiply by "a and
30 and s and 50 80, and you will find he
had to pay about $50 when no got home
