From an Exchange.
Just the same gas that sparkles up

payne. or that makes the holes in loaf
Of bread Is to be manufactured in enor-
nous quantities at waukegan and brought
to Chicago consumers by pipe line.
II Will used as refrigerating and pre-
Serving medium. as fire extinguisher and
as a protection against such insects as
prey upon furs and wooleh goods.
This new and practical application Of the
valuable properties of carbon dioxide was
discovered by r. F. Osborne. a thermic en-
gineer. who has been five years in perfect
ing his discovery and making its use prac-
ticable from a commercial point of view.
In explaining his theories yesterday Mr.
Osborne dropped some blazing brands into
a large vessel filed with gas. Before the
brands had touched the bottom OF the YES
sci the flames were extinguished. A small
er vessel was filled with the gas, a can
die was lighted, and the invisible and odor-
less contents Of the vessel We're poured
over the candle The flames were extin-
guished, the wick not smoldering an in
stant,-
so much for carbon dloxide as fire ex-
tingusher," said Mr.. Osborne. See, now
what it.can do as a refrigerating medium"
Mr.. OFbornes son placed thermometer
in a champagne cooler which was encir-
cled with a coil Of pipes. When placed in
the cooler which contained no ice the
thermometer marked 76 degrees, the tenn
perature OF the room. The gas was allowed
to enter the cooler by system of pipes
connecting with a metal cask. In four
minutes the thermometer was removed 1t
marked 30 degrees below zero Fahrenheit.
This gas is readily adapted for use insre-
frigerator cars and will preserve with
a dry atmosphere and will keep in frozen
state all goods which enter the cars in
that condition.
Carbon dioxide as refrigerator is now
in practical use, but thu expense of manu-
featuring 1t is very great. 1t costs from
8 to rs cents pound. Under the old sys-
tenn ii was made only from certain stones
imported from Italy and Germany. Mr..
Osborne makes 1t from limestone and soft
coal and II could be sold in competition
with Ice a. u cents a ton. 1t Is neutral
gas and comparatively harmless. 1t Is
odorless and neither inhamamble, corro-
sive nor explosive, and in a few min
utes will produce a temperature of 100 de-
grees below zero. IL is the best preserva-
tive OF WOODEN goods and furs known. keep
ing them from the ravages OF insects and
worms without giving them any odor. II
can be used advantageously for sewing
machines. fans, ice cream freezers and
sausage machines
The plant in Waukegan, which is now
in course of construction, consists of
central producing station provided with
gas producers, retorts, distilling apparat-
us, boilers, engines. pumps, conapressors
and incidental apparatus.
The raw materials required are soft coal
and limestone. The products are carbon
dioxide, commercial lime, carbonate of am
nonia and coal tar. The coal is sup
piled to retorts and subjected to destruct-
i've distillation in nearly the same manner
as in ordinary gas works, the tar and am,
moniacal liquor being separated, the for
mer being sold in its then state and the
latter distilled and converted into carlo,
nate Of ammonia. packed and sold.
The coke resulting from the coal distill-
ed is converted into semi-water gas, which
Is used to distill or calcine the limestone
The lime produced is of good quality and
Is sold on the open market either in bulk
or by the barrel
