All by Turning Tap.
every man his own iceman" is the
watchword of the future.
A company has been formed to send
eoolness around in pipes, SO that a man
eau turn IL tap in his own house and
produce IL temperature of 100 degrees be-
low zero us easy as wink.
This scheme simply is the we'll known
plan of icenaking by the liquefaction
and subsequent re-evaporation of gases,
except that the gas is carbon dioxidc in
stead Of ammonia, and that it is convey
ed around town in pipes in liquid form
and applied to anything that is to be
cooled or frozen. The raw materials
used are soft coal and limestone. The
products are carbon dioxide, CONNER
cial lime, carbonate of ammonia and
coal tar. tits by producing the last three
together with the dioxide that the di-
oxide itself is made cheap enough for
general use. The coal is supplied to re-
torts and subjected to destructive distil-
lation in nearly tho same manner as in
ordinary gas works, tho tar and am
moniacal liquor being separated, the
former being sold i'll that state and the
latter distilled and converted into car
Donate Of ammonia, packed and sold.
The coke is converted into semiwater
gas, which is used to calcine the lime
stone. The dioxidc is cooled, purified,
compressed and iquified in the same
way as i'll other manufactures and then
conveyed by its own pressure through
distributing pipes or sold in vessels, as
may bo preferred. Ono good ton of soft
coal and 3la tons of limestone, it is
said, will produce $500 pounds Of lime,
5000 pounds of carbon dioxidc, & gal
Ions of coal tar and so pounds of car
Donate of ammonia.
The prospects Of comfort, cleanliness
and economy held out by the company
arc enough to produce the most delight
full comnotion in the breasts of house
keepers Of course tho first point to
which every one will want the dioxile

than thcrmostat, which regulates tho

frigidity desired, and the moment that
limit is reached the dioxide is automat-
ically checked.
Ice cream is what the dioxide particu-
larly delights in, Tho freezer is encir-
cled with a aooil of pipe, and when the
dioxide rushes through that coil the
cream congeals before one can count ten

necessary to stir the cream as it freezes,
and this, too, is done by the dioSide,
for the waste Of tho gas is turned into
an engine, tho engine works a crank,
and the crank turns tho freezer and stirs
the cream. This invention also furnishes
leo water without ice. A great many
people would rather drink warm water
than water into which leo Of unknown
antecedents had melted. But hereafter
he has only to set his drinking water in
tho refrigerator and be sure to fix the

means Of alleviating the patients suf-
ferings and sometimes saving his life.
A coil of pipe may be arranged in a mar
row space between q wall and a screen,
and draft at once will be created which
will lower the Temperature OF the room.

heat Tho device, therefore, is certain
to become. at some time or other, enc of
the best appliances In we'll regulated
hospitals.
From these solemn uses the dtoxide
may be turned to others, which are
enough, on the first flush, to cause a
smile. For instance, it will furnish abb
solute security against the ravages Of
moths. What people need who have
costly furs to preserve through the sum-

but they will be dead, for no moth can
live in this gas,
Finally every customer for dioxide
becomes his own fireman. If he comes
home in the evening and fluds his house
or fire, he will not run through tho
street screaming fire and turn on an
alarm. He simply will turn the dioxide
tap and then watch the flames wither
and die. The dioxide is as fatal to. fire
