CT ia ING WINTER.
The Artificial I.ctriscrating Process in "a
Grcas Brewery.

GrcAs brewery.
\ frivul OF mine, an American born man,
wLoowns large bravery, took me through
i: last week, and gave me thc rare treat Of a
man ofleau,iug able 20 describe the sticn-
tifc processes he followed.
Going IN from the street through
an archway, the place looked very
modest, but when We came to grope
for two or three acrrs under ground,
with candles in our hands, and the sewers of
the city far above our heads, and the cell
iugS ofthe great vaults covered with ice and
snow in the midst of August, could not but
be astoniShcd Yet this is not very large
brewery, and il turns out only about 5000
barrels of lager year. II is the only
brewery in the world, however,
with the exception of one in Williams =
burg which does not use any ice, but makes
itS own cold by absorbing the heat In the
vaults by rcfrigcratinC machinery, For
merlv il consumed $500 to 10000 tons of ice
year, which az the present low rate Of 81 a
ton, would make in the ncighborhoOd of
$4,000. My companion had a friend
working with him who invented the
machine, which acComplishes more cold
than all this yaSt-.inaSS of ice, snd AT
the same time saves the room the ice would
occupy for the storage Of beer, thereby en-
larging the brewery 20 that extent,
for a brewery is in the MAN. q stock OF beer
kept ripcning weeks or months. The mere
brewing is a simple matter, and here they
brew fifteen times week, using the same
series of kettle, hop-boilcr and
main tub All that would be neces-
Sary TO brew more would be TO put in an
other kettle and accessories, but to carry
the beer in any great quantity you must
have vault room, which is expensive, and
you must have cold room, which You Dan
only obtain by ice or by science
What is the principle, said |, by
which you create winter at all ~
"We'use 200 pounds Of aqua ammonia,
which costs about ~ cents q pound. That,
by our powerful engine, we compress and
drive through many hundred feet Of pipes
which lay along the tops of our vaults, and
we also run il down through
our fermenting tubes in hollow cylin-
dcrs. We produce expansion in this am
monia by needle point aperture which at
certain places give il outlet. In the act of
expanding it takes up heat and produces y
temperature only a few degrees above the
freezing point while the pipes them
selves become incrusted with what
ever moisture is in the vaults In the
cost $4,000, or about two years coat Of our
ice. We havejust put up one in Williams
burg for somewhat less money. To buy an
iCc-house costs brewer from $D, 900 to 500,
60. There are some which cost $4,000,
But after you have built your ice-house You
have to buy your ice, and that being bulky,
takes SO much from your beer
The day is close al hand " he continued,
when this machinery will be supplied to
hotels and will keep the cityof New ! Ork rs
cool in midsummer q. the sca.de or
the mountain tops. You can make the
temperature what you please. You
can cool the theatres SO that they can get
four or five months more occupation
1T is certainly mysterious, said l. that
tn about $500 worth of hartshOrn you
can expugn $1,000 OF ice, and make m Y
toes ache down here in dog days" What is
ammonia
1T isl compound Of hydrogen and ny
drogen, and is called ammonia because
il was first made at the Temple OF
Jupiter Ammon, on the hot
deserts Of Africa. 1t is called
hartShorn because they once made it out o
the decomposed horns of deer. You buy il
rs liquid. II is a powerful alkali. Every
thing in nature, you know, normally cold
The heat comes from elsewhere, and all W,
dniS to take away theheat by letting The
hartshorn seize il and carry il away. w,
use the same hartshorn from day to day
and from year to year, over and over again
