ARTIFICIAL ICE.

AN APPARATUS WHICH WILL TURN OUT THIRTY
TONS OF CLEAR ICE IN DAY-How 1T IS
DONE. e..
Tho ice factory recently opened in est Eleventh
street visited yesterday, and Il proved TO be
object Of much interest The ice, produced In blocks
OF about i've hundred pounds each, measuring four
feet square and nine inches thick. clear that

oiaI through the entiro thickness OF tho block.
Printed bills and bottles OF champagne wero
frozen tight 10 tho ice The bills were read with the
greatest through the sido OF the block in which
they had been embedded. A thermometer marked
with Farcnhcirs scale was frozen the block at a
point marking nineteen degrees below the freezing
point.
HOW THE ICE MADE.
The Ice generating apparatus run In the present
instance, by steam engine OF twenty horse powor
On The right hand oil the engine is the re.
irigerstor, copper tubular vessel, enclosed
IN wooden box about six or seven
ieot square. The refrigerator is charged with
liquid ether, evaporaed, when required, by u vacuum
pump. which stands on tho LETT Of the engine and
connected by copper tubes with the refrigerator The
other 10 drawn away tho form OF vapor and passed
into u pper tubular condenser where, under low
degree Of pressure, aided by stream OF water, II rs
again brought back to It's original state returns
through the ether cooler meter which regu-

n strong, uucongesabe brine Is circulated by n
chine called the brine pump through the tubes OF the
refrigerator parting with It's heat TO the ether vapor
