6fVe Coal Oil

sive Coal OIL.
For years the danger of coal oillamps
and coal oil in the hands Of careless
persons have been the study of those
who sought to remedy the evil by scien-
tifcally reducing the dangers to almost
nothing. The benzine in all coal oils is
the inaammable and explosive property
which generates that terrible gas in
lamps which has been so fatal on many
occasions. Mr.. Urquhart, of Urquhart
4 Co., 1874 Main street, in this city, has
for fifteen years been investigating this
subject, he having, as a large dealer, a
due regard to the wants of the public for
a safe illuminating oil. Through their
manufacturers, Mr.. Urquhart has
had numerous experiments made by
which it was sought to eliminate the ben
zine from the oil and at the same time
produce a safe, brilliant and economical
light, and at last he has been successful
in producing the Crystal Headlight
Coal Oil, which preeludes all possibility
Of accidents arising from the use Of dan
gerous and combustible compounds
styled non.explosiye oils, etc. The
Crystal coal oil is manufactured from
superior crude, is entirely without color
or smoke and burma in any kind of lamp
as brilliantly as gas, while at the same
time it stands fire test of l750 Fahren-
heit. 1t will not burn without something
to act as wick, and is therefore
as harmless as water about a house.
Our scientific reporter witnessed several
tests made as to the inhammability and
explosiveness Of this new oil. A pint OF
it was poured into a tin pan; it was i'm
possible to light it from burning match.
The same quantity of coal oil when
touched by lighted match commenced
flashing and throwing off the explosive
benzine gas, and Immediately the oil
iguited and blazed up in q most inham-
mabIe manner. A mass of wick was
placed in the Crystal coal oil and satu-
rated. When tonched by burning
match it blazed brilliantly, and when the
entire mass of wick was blazing it was
placed back in the tin pan, when 1t wai
extinguished more suddenly than |
it had been thrust into water. Wher
the same test was applied to thu
best quality of coal oil the fir
Immediately ignited the oil in the pan
it blazed up fereely, and was with diff
Guilty extinguished. You can pour thu
oil down the glass chimney when the
lamp is lighted and no explosion will
take place. you can, when the lamp is
lighted, take off the cap, pour the oil
into the lamp from can, and no danger
need be apprehended. If you pour the
oil on lighted fire, the oil will extin'
guish the FIRE as suddenly as would
water. No person can light fire with
it, and in doing this with coal oil many
frightful accidents have occurred, owing
to the carelessness Of servants and chill
dren. Ifa lamp falls and breaks, the oil
not being inAammable, no fire takes
place, and no damage can follow. Its
burning power is equal to the best gas
light, many times more brilliant than
any other character of coal oil and the
consumption is thirty per cent. less.
Where gas is oris not used, the Crystal
Headlight Coal Oil becomes a safe lux
ury, most economical and wonderfully
brilliant in fame. AS no gas generates
from it in the vacuum or chamber be-
tween the surface Of the oil and the cap
Of the lamp, no explosion can possibly
take place. 1t burns with a white,
steady flame, never Pickering or snap
ping, ana throws off no smoke; hence
smoky chimneys cease to exist.
Urquhart & Co. have no hesitation in
advising their friends to use this oil at
their residences. Ask your grocery
merchant for Urquhart & Co.'S Crystal
Head Light Coal Oil; take no other, and
thereby secure for yourselves an oil
brilliant, safe and economical. 1t costs
but fifty cents per gallon at the house
of Urquhart & Co., 1874 Main street,
near Union.
