Grows.

The people OF Keokuk may well take
nride in its artificial ice plant. 1t is
81 the most modern type. and arrang-
ed throughout with the idea Of purity
and ease of handling always in view.
Last spring when the scarcity of
natural ice was noticed, local capital
secured the cooperation of men who
were familiar with the ice manufactur-
ing business, and not minute was
lost in getting the enterprise under
way. Time was short before the warm
season and much had to be done. The
buildings at the corner Of Eighth and
Johnson streets were bought, because
90 well adapted to the purpose, being
centrally located and on the c., B. &
O. railroad tracks. A local contrac-
Tor was secured who is in the habit
Of doing things on time, and G. e.
Lindstrand started In with a vim
born OF ability and keen interest in
the enterprise. The most up-to-date
refrigerating machinery was ordered.
and 1t is peculiarly fitting that 1t was
made by former resident OF Keokuk,
P. Dec. Ball. now of st. Louis.
The trick has been turned and the
plant has been making Ice for sew
eral weeks. The good people OF Keo-
kuk have taken great interest In the
undertaking, and have been generous
in their patronage OF the new indus
try.
The capacity Of the plant Is large
enough to meet an increasing demand
as Keokuk grows, and daily carload
shipments are now being made to the
surrounding territory.
How Ice Is Made.
Many questions ere asked about ice
making, and ei- = explanation Of
the process may | .eresting to the
public.
To understand il me must bear In
mind the well-knCwn fact that, in or
der to change matter from one state
to another. heat must either be put
into 1t or withdrawn from It. In the
case OF water, for instance, the solid
state called Ice is changed to the
liquid, or water, by the absorption
Of a certain amount of heat. The
liquid is again changed to gas, cali
ed steam, by absorption Of a large
amount OF heat. This Is true of all
substances such as alcohol, carbon!c
acid, ammonia, mercury, lead, iron,
etc. The temperature at which the
change takes place, however. varies
70 great extent. For instance, salt
water freezes at a lower temperature
IMAM water not salty, and this fact

else that is liquid at ordinary tenn.
peratures, is how to get the heat out
OF It. In the case OF ice cream salt
IS put on the ice, which forces the ice

IN order to change water from the
solid to the liquid state heat must

source OF heat In an ice cream freez-
er Is the cream, and SO the forced
melting of the Ice pulls the heat out

In the manufacture of ice heat must

while the explanation of the process
IS Just as simple as in ice cream
