WooD AND GUEPowDER IsCoHBUsTIBLE.-The day
u FIRE annhlatofs does not to have entirely gone
by. French artillery officer has made a singular
discovery, by which all danger from explosion of q
powder magazine may be prevented. His method is
- mir the powder with common coal dust Its efficacy
has been demonstrated on large scale, by filling
magazine with the mixture, and then setting it fire,
but no explosion took place, and after burning con-
siderable time, the fire was eItnguishsd by applying
water The gunpOwder burnedlke other cOmbustible
matters, such as pitch or tar from which it 10 pre-
pumed the dust must have been that of bituminous
coal. When the powder is required for use nothing
more needed than to separate il from the dust by
means Of sleeves when il its original explosive
property The theory Of this curious discovery is very
simpe-the dust prevents the several grains of pow
der from coming in contact with each other hence,
enc eIpodes the dust prevents the explosion from
sesehng another grain But fire annhlating discov
cry which smuch more likely TO become generally use
fu has also beenmade in France by NJ. CarperoD, who
has proved tie value by experiments made in
presence of the Emperor. The process renders wood
Tissues Of all sorts dresses decorations &C., absolute
~ incombusble. Ladies dresses Of the most gauz''
NE materials were set fire to- and would not burn An
sf6cers tent, containing bed with muslin curtains,
resisted successfully the application of numerous nam
ing torches cottage, hall OF wmch was secureu ny
n. Carperon's PREPARATION and the other hall hlled
With straw, was set on fire the unprotected side.
The flames quickly spread and ragged with fury, and
consumed half of the building; but the fire died away
when reached the prepared part, and left it sound
and altogether uninured theater wasthen prepared
with all ts scenery robes and decorations and repeated
attempts were made TO destroy by fire, bat in van-
il would not burn. Such discovery introduced into
our cities and applied to the dresses of the ignorant
Irish and German girls who so frequently burned
alive by using camphene, would be great blessing.
Another French eontrivance not exactly of the same
order noticed in recent publications. Its object is to
economic fuel an article which is enormously dear in
Paris and all other French towns. II consists of mere
pipe Of thick sheet ron into which logs of wool are
thrown and beneath which the fire sighted. This con-
tivance produces much heat that the apartment is
thoroughly warmed during the day. and nghttle logs,
completely charred, but not consumed are Withdrawn
o. charcoal and will sell for double their original cost
as wood The inventor of this chimney lie NJ Renaud,
and the French journals anticipate great things from it,
But il would seem to be only modification Of the
wen-known American alright stove, which vas highly
recommended by old woman about the time 1t was
hst offered for sale who declared that in the morning
che put three cents worth Of wood into it, which kept
her warm all day and night aud that next morn
ing she had siIpence worth Of charcoal to sell.
