ICE.
How It is Made, etc 1.-The Beginning Of the
Trade In Memphis.

On Sunday morning next viii appear in
the APPEAL, the card OF the Memphis Ice
Company. This concern was started at
the suggestion and under the ~reasOnings or
the APPEAL LOCAL, during the ice fam
inc, and therefore we feel that we have
the right to blow - somewhat. We pre-
sent below a sketch of the manner in
which ice is produced, promising TO give
full description of the ice mandatory as
soon as it is in operation. Among the
startling discoveries which are the distIn-
gushing feature of the present age may
be reckOned that of manufacturing ice
cheaply and in large quantities, as has
been done in Southern cities. The discoV-
cry of the process is due to the science
Of chemistry; the science which has
given Us printers ink, gun-poW-
der, steam and electricity, those potent
agentsthathav revOlutionized the world;
the numberless useful and beautiful aP-
planes of modern art; the principal inn
prOvements in modern agriculture, and TO
which, in the future as in the past, man
kind must look for the most important
results. Tho increased use of ice in hot
climates which this cheap and abundant
mode of supply will occasion will be
highly beneficial in a sanitary point of
view. What moral effect the use of such
a cooling article nay have upon the more
passionate natures of the people of those
regions may be left to experience and So
cial philosophers to determine. Unless,
indeed, the chemists, who are an
inQuisitive and INSCRIPTIONS race,
should 90 further and cOunteract such
effect, by discovering a cheap and ready
method Of manufacturing spurious Ii
quors, when juleps would more than ever
abound and temperance reformers be in
despair. The materials used in the manu-
facture of ice are spirits of ammonia, salt
and steam. The retort is used for heat
ing the ammonia. A coil of pipe through
which steam passes, winds around the
interior. Eight hundred gallons of the
ammonia are poured into the retort and
about Jwenty-fOur pounds of steam ap-
piled. The gas arising from the ammonia
is conveyed into a pipe at the top of the
retOrt. The pipe passes into a cooler
filed with water n theme to the lique-
fer. 1t is now thoroughly chilled and
deprived Of its carbonic principles and be-
cOmes a freezing liquid. Connected with
the condenser is a pipe, which carries the
liquid into a series of pipes that diverge
through the freezing box. The latter is
filed with a strong solution Of salt and
water, which, with the aid of the liquid
ammonia in the pipes, causes an intense
cold, the frost collecting upon the pipes
where they are exposed to the Amos
phere. Into the freezing box are intro
duced fOrty-eight brass boxes, filled with
fresh water, each of them producing a
t~wenty-four pound slab of ice, four
inches in thickness, two feet in length
and one in breadth. 1t requires four
hours to freeze the fOrty-eight boxes.
establishment for making artificial
ice has been in operation in New Orleans
for a considerable time, and has proved a
success. 1t produces ice very rapidly and
Of excellent quality. The ice is not so
and beautiful as that from the
North lit has rather the appearance of what
is called snOw-ice, but it is very hard,
containing a greater amount of cold than
other ice, and d~issOlving less rapidly in
water or in a warm room. It is sold
cheaper than common ice, and there is a
on the spot for a great deal more
han can be manufactured. The concern
IS said to be very profitable. 1t would in
deed be a singular thing if the artificial
supersede the natural article in
his land Of ice.
