Among the instruments invented
for the preservation of life at sea that
will be experimental with before the
board of supervising inspectors OF
steam vessels in Washington Septem-
Der 2s will be an oil projectile and dis
tributer. 1t is an apparatus for
spreading oil on stormy waters, and
is the invention of Mr.. Everett ID.
Moore, of Baltimore, and has just
been patented by the American Oil
Proiectile company, Of which ex-Gov-
ernor Groome is president and Col.
Washington Bowie secretary and
treasurer. From private experiments
made the projectile seems to be des-
tined to be the apparatus that has
long been wanted Tor discharging oil
on the sea from the decks OF storm
ridden ships, and from the beach to
stranded vessels. The proiectile is a
simple contrivance, and is operatedb by
being fired from a cannon. An opera
ting rope is attached to a rod at the
side OF the p%rojectile, and by this
means when il strikes the wa
ter it is handled from the point
where it was fired from by
being hauled through the wa
ter back to the ship or beach. As
the projectile travels back the water
goes into one end. The oil thus
spreads out over the surface and
makes a smooth road over the agi-
tated waters. At Bay Ridge recently
the projectile and distributor were
tested with good results. From a
small cannon heinstrument was fired
about five hundred yards off shore.
The water was in a state of moderate
violence, the waves being white
capped. From the point where the
proiectile dropped back TO the beach
a smooth road was left over the route
the oil a discharged on, and the
white-caps disappeared entirely.
With but three quarts of oil in the
distributor, a smooth surface wide
enough was made TO permit two
steamers to pass abreast. If the pro
j~ectile stands official tests it will be an
invaluable aid in the preservation of
the lives Of those vino 20 down to the

Economical Production Of Carbonic
Acid for Industrial Purposes.
The utilization of waste products is
the order Of the days An interesting
article on this subject, in relation to
breweries, in the Brewers Guardian,
calls attention to the utilization OF
the carbonie acid gas produced in the
fermentation Of sugar. "On an aver
age, English beer may be said to con-
tain ; per cen of alcohol, and as, in
the fermentation OF sugar, the weight
OF carbonic acid produced is almost
the same as that of alcohol, the exact
| proportions being 4S.9 of carbonic
acid to Sill of alcohol. there must
ic acid produced in our breweries.
The specific gravity OF carbonic acid
is 0.1524, AMI therefore a simple cal
culation shows that the above weight
is equal to 5,O00,O DOC, 900 gallons-a
volume it is almost impossible to
realize; such a volume would requires
space one mile square and forty yards
high to contain il. 1t is now proposed
to utilize the greater portion of
this large quantity OF carbonic
acid. The process by which this is to
be done has been tried for some little
time past in st. James's Gate GUM.
ness's Brewery, Dublin; and Sir
Charles A. Cameron has reported
favorably on it. The following are
the conclusions at which he arrives
after a most careful examination of
the process: /, An immense quantity
, OF carbonic acld is produced III brewer
les, and it is at present wasted; ?, a
large portion ofthis gas could be con-
densed to liquid at a cost not exceed
ing I'D. per pound, but probably less
than Id. per pound; 3, the process OF
liquefying the gas is successfully car
ried on at Guinness's Brewery Dublin;
4 the liquefied gas prepared at GUM
nesss Brewery is perfectly free
IRON any popularity of flavor
or odor; >, the carbonic acid
produced at soda-water works costs
about Id. per pound; 6 it is safer and
in every way more desirable to use
in beverages carhonic acid de
rived from n food substance, such
as grain, than from mineral sources;
Z the uses OF liquid carbonic acid are
numerous, important, and mcreas-
ing.
