AUTOMATIC REFRIGERATION.

The Scientific American of this
week contains a very interesting de-
:, scription, illustrated, ofthe automatic
refrigeration enterprise Of Denver
This seems to be new thing under
the sun, the supplying of cold air to
consumers through pipes, In much
the same way that water and gas are
now supplied. 1t is two years since
the work was begun in Denver and II
has been sufficiently extended to
demonstrate its success. Over two
miles of mains have been laid and
are now In successful operation, and
the service admits of about one hun
bred and fifty connections to the mile.
For these service boxes are provided
at the sidewalks. The storage room
is 40 X $50 feet and in connection with
it cold storage warehouse is con-
nected. The design of the company
is to provide thorough refrigeration at
q lower cost and In q more per-
feet ma nner than can be accomp-
lished by ice. The storage tanks at
the central location are virtually ex.
tended into and include the mains so
that the delivery is made of the cold
current at the stipulated temperature
and this temperature maintained in
the service boxes. The company has
franchises covering the streets and
alleys of the city of Denver and will
extend their mains so as to include as
much of the city as may be desired.
The system of producing and con-
veying cold air employed by them is
covered by some twenty or thirty
patents, among them one which
applies to the storage of the
surplus refrigerant, to be drawn as
wanted. Anhydrous liquid ammonia
is employed, one pound of which has
the same refrigerating power as three
pounds of ice. The service is perfect.
All accumulation of gas in
main or branch lines is auto
metically returned to the GEN.

Even the odor of the various foods Is
by this system which is
dry refrigeration, and
there is no lice box taste" to the most
delicate foods. Different tempera-
lures are arranged for at will, and
that temperature suited to the most
perfect preservation of the products
stored. The Denver club house, one
of the most perfect in the country,
and we'll known throughout the Uni
ted States, is supplied with refrigera-
ton from the Colorado Automatic
Refrigerating company's mains. This
club house is nearly q mile dis
tant from the central station,
has six different compartments
in its refrigerating room each
m lintajning different temperature.
One for fruit at about As deg. fab,

fab, one for wines and liquors at 40
deg. fab, and one for freezing
carafes of water, ice cream and wines
at about 10 deg. below zero. Fresh
meat, poultry, game, fish and all
kinds of delicate food are thus readl-
ly preserved for weeks, in the warm
est weather, obviating the waste here.
