A Detroiter's Scheme for Fire Protection
and Sanitstion-J. 4. Andrews.
Indefatigable J. z. Andrews, OF Pictet
fluid fame, has only been spurred on to
greater mental activity by the reverses to
which he las recently been subject and
which deprived him OF a large part OF a
once comfortable fortune. BESIDES negoti-
ating for the contract of extinguishing the
big fire in the Calumet and Hecla mine, he
has perfected an invention which may rev.
olutlonize the systems of fire protection and
sanitation in cities, in addition To affording
the broadest possibilities in other directions.
This is partially what AR. Andrews Will do:
He will fusten tank on the side of build
ing at each floor, and connect il by means
of pipes with each room on that floor.
he will fill the tank with some liquehed
non-in fiannable gas. The apparatus will
then be ready for use. Should q fire take
place on the floor the tank can be safely
reached, as it will be on the outside OF the
building. The turning of tap will then
fiH the rooms with tine gas, and the eItnc-
ton of the fire will be instantaneous. There
wilt be no water or steam TO damage car
pets. pictures aud furniture in all parts of
the building, but the ire will disappear. Ii
must, fer the gas will shut out the air neces-
sxry for combustion.
1t is Mr.. Andrews intention to use with
his apparatus the wonderful Pictet fluid,
which is made up OF gases Compressed into
LIQUID forn.t~He will then not only be
able to extinguish tbe fires that may take
place in the buildings supplied with the in
ventien, but TO disinfect them thoroughly
as well. Should the Injunction restraining
him from manufacturing the Piclet fluid be
maintained. however. he vii. hquefy other
gases which have the same effect, and use
them instead.
Placing tank at cash floor will not be
necessary under Mr.. Andrews system. He
can arrange Tor one tank to supply whole
block. This tank may be placed in the mid
die Of the block, and pipes carried from it
TO the neighboring houses. A great saving
will be effected in this way. The tank for
the whole block need not be any larger
than those on single buildings, for the rea-
son that II will be necessary to treat only
one place at time, as a rule.
Perhaps the most important use to which
Mr.. Andrews proposes to apply his iDven-
ton is the jisibfection of sewers. He will
place his tank with pipe leading away
from it q lew feet into the sewer and
charge it with the liouefied gas. As often
as may b. considered necessary, then, a vol
ume of disinfecting gas which will nil not

it from closets aud SINKS, will rush cut and
destroy the foul snle Is aud germs that are
every busy at creating diphthtIs, malsriai
fever, scarlet fever and typhus.
Il was arranging With the Board of Pub
lie Works IN London, England" Mr.. An
drews says, for the introduction of such a
system in the sewers of that great city,
when Raoul Pictet refused TO carry out
agreements We had made. and thus rendered
me powerless to some extent. The mem
bers OF the Board, however, were much
struck with the ides and expressed them
selves IS feeling very much inclined to
adopt the plan. / would have had al enor-
nous contract but for Pictet.'
The tank is designed for use on steam
ships and on refrigerator cars and in mines,
as the gas to be used will either extinguisn
fires, oisinfect or preserve meats. A patent
has been applied fos.- Detroit Nej0s.
