from the water through the opera.
ton Of the wcll-kuown law that
liquids in passing into state Of
vapor absorb vast amount of heat.
Thereby the temperature of the
water in the tanks is reduced below
the freezing point Of - degrees, and
it crystallizcs to iron plates on the
side next the conductors. From the
point Of expansion the conductors
have a thick and hard coating of the
purcst white frost, caused by the
moisture in the surrounding air
crystallizing Us it is robbed of its
heat The moisture is visible some
inches from the pipe, like PERSONS
breath in winter atmosphere. This
phenomenon is also observable on
the conductors leading back TO the
pump, but is absent on those leading
from the pump to the condenser,
where the ammonia has entered upon
the transition back to n liquid form.
From this curious condition, Mr..
Orth calls one side of the pump
winter and the other summer.
Freezing evenly from one side 10y
this process, any PARTICLES of foreign
matter being pushed to the outside,
the ice is rs solid and pure rs that
formed upon the rivers of the far
north. After completing its circuit
in the tanks the gas is drawn off and
pumped back to the condenser to
resume its journey, the ammonia
being in constant circulation, in its
different states, while batch of ice
is making. Each of the six tanks is
ten feet long, four feet deep, and
% inches wide, yielding As slabs of
ice, each weighing about lS00pounds,
at each freezing, which occupies
from three and half to four days.
All the water remaining after a freez-
ing is drawn off, and the tanks re-
plenished for the succeeding opera
ton with filtered water. Air is eX-
cluded from the tanks by plank and
canvas coverings.
When the manufactory started,
the process employed was that of
freezing in closed vessels, but that
was discarded as unsatisfactory, the
ice so formed embracing any impuri-
ties that might be in the water and
the block being liable to be soft in
the centre.
The motive machinery mainly con-
sists of an upright engine, lG inches
in diameter and "a inches stroke,
and pump, II inches in diameter
and "a inches stroke, working on one
shaft, having massive hy-wheel of
four tons. Besides these and the
other machinery and apparatus al
ready described, there are complete
appliances for protection against fire.
The boiler, 6 #. l6 it., is in q
building by itself, mounted upon n
substantial brick furnace and every
! precaution against fire is observed.
One ton of coal is consumed for
every five tons of ice produced.
There are two storc-rooms on the
premises, one Is feet square and Q
feet deep, and the other #. y 1S
IT,, same depth, with total capacity
of about 100 tons.
This manufactory has now been
established about twelve years, hold
ing the honor Of having introduced
the luxury of ice to this land of
perennial summer. 1t is now in q
high state of efficiency, under the
constant personal superintendent of
NJ. j. X. Wilder, and is in posi-
ton to challenge competition in the
quality Of its product and otherwise.
To Mr.. Tucker much credit is due
for the perfection of the process en-
ployed, he having designed the whole
method and achieved success by
patient experiment. As useful
enterprise, which has overcome
formidable difficulties, the Honolulu
Ice Manufactory is one of the most
deserving of success of all our local
industries. The firm wishes its
