especially would like to know how
large storage room l can cool to the
proper temperature with given
amount of ice in the building, Also
what is the best temperature at which
to keep the cold storage room for milk
preservation and for general domestic
purposes? NJ. c..
A cold-storagc house should be built
with the same care, and on the same
methods, as an ice-house; as to keep
cold in house required the same meth
DDS rs to keep heat out. The walls
should be non-conducting, and while
the ice is not kept in the house, but in
u receptacle above it, made like an ice
house, yet to retain the GOODNESS of the
lee above the cold chamber the mode
of constructing this must be the same
US for an icc-house.
1t goes without saying that ventila-
ton is wholly fatal to the maintenance
of Il lower temperature than that out
side the building. The object is to re-
tain n temperature AS near the freezing
point as possible, and yet not to per-
nit freezing. Any method of ventila-
tion will necessarily be fatal to this.
30 that as the purpose of ventilation is
- preserve the purity of the air in the
cooler, and this may be done by other
means, these must be taken; and en-
trance of air from the outside is be
avoided.
As the impurities that will gather in
a cool chamber will consist of moisture
derived from the contents of the cold
closet, any method of condensing this
and gathering it will be equivalent to
the effects of ordinary ventilation,
rs it will purify the air by taxi
ing from it these impurities with
the moisture of it. This is done
most effectively by the use of fresh
stone lime, which absorbs one-third its
weight of water from the air about it,
and as dry air is pure and free from all
matter that may be suspended in it be-
fore it is dried, the purity of the closet
is secured by this use OF lime. A sup
ply of the fresh lime is therefore all
that is needed for this purpose. AS it
becomes saturated with moisture it
falls to Il dry powder which is the hy-
drate of lime, and is then replaced by
a fresh supply. The lime may be kept
in pan in the house.
The ice is used in this way: Above
the cold closet there is receptacle for
the ice-house is-that is, by double
walls and double door through which
the ice is put into it, The floor of this
ice chamber is of metal us the best
conductor; galvanized iron or sheet
zinz is the best material, and this
is SO disposed that the wa
ter from the melting ice will flow tc
one corner, where drain pipe is fitted

ARA curved trap made like an 5 laid

of safety to have two of these, one il
the closet, through the corner of which
the drainage flows, and another out
side at the entrance into the drair
through which the waste water es
capped.
1t is impossible to say just how mucl
ice will be required to supply any sor
of cold-storage closet 1t depends upol
the mode in which it is constructed, OF
the size of it, and on the quantity o
stuff in it to be cooled. The best TEN

degree something will be damaged
