factory on Water street, 10 West Washington, and
learned the business OF making artificial ice, and
had portion OF the requisite apparatus built
here-that is, the tank, which is q heavy wooden
box, i7x35 feet and feet deep, OF pine, in three
compartments. 1t was built by Mr.. Sebastian. OF
West Washington, and is now ready for shipment.
The pump was made I'm New York, and q portion
of the freezing boxes and coils In Philadelphia,
and portion here. The capacity OF the apparatus
complete viii be four tons or ice per day, and as
population OF the place 60O6. with three other
towns near by, the captain expects to make some
money by his venture. The machine is a small
one, OF the same pattern as the one here which
has daily capacity OF 40 tons. The tanks OF the
machine here when full hold 4SO tons OF ice being
four tanks OF 120 tons each. The company claims
season to $2 rer ton, but say the other companies
are all friendly to 1t. Notwithstanding.
THE PROCESS OF MAKING ARTIFICIAL ICE
at the mandatory In West Washington has been
fully described In The STAR heretofore. Ammonia
is the principal agent 1t is placed in condenser,
and at pressure 120 pounds to the square foot 1t
liQuff1es Pipes run from the condenser to the
tanks where the ice forms valve being
opened the condensed ammonia is allowed to
go through these In the form OF a gas
into the pipes In the tanks. which are ar
In the form OF boxes, completely incasing the
pipes. There are forty OF these boxes. The
ammonia. expanding through these pipes, takes
the heat from the water, which causes It to freeze
AFTER the heat Is thus taken away from the water
and taken up by the ammonia, 1t Is removed from
the ammonia by passing 1t through large coil OF
pipes, called "cOOler." 1t Is then forced by q
pump back into the condenser, ready to do the
work over, and the process Is repeated again and
again. The ammonia passes through Il 200 feet
OF the freezing pipes before IL is forced back into
the condenser TO be made ready for another freeze
The plates spoken OF as incl0sing the freezing
pipes are mainly for the purpose OF giving the
water something to freeze upon. The ice forms
against the plates, which are placed at right
angles to the floor OF the tanks The novel spec

ceSSful use for seven years. Another f. In the
Sandwich Islands, used successfully for eight
years.
All the water used at the mandatory here is
filtered, making in fact perfectly pure and trans
parent ice which is put directly into wagons from
the freezing tanks by means or an inclined plane
passing through the factory to Water street.
