THE COLD STORAGE HOUSE.
A Valuable Adjunct TO Any Well Regu-
lated Farm, But 1t Needs Care
In Construction.

in Construction.
/ want to build cold-storagC house
for my family and farm use. and should
like instructions, particularly with re-
gard to ventilation and insulation. l
especially would like to know how
largo storage room | 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
pul lposes? Nj. c.
A cold-storage 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 as to keep heat out. The walls
should be non-conducting, and while
the Ice is not kept in the house, but in
a receptacle above it, made like an ice
house, yet to retain the coolness Of the
Ice above the cold chamber the mode
of constructing this must be the same
as for an ice-house.
1t goes without saying that ventila-
tiOn is wholly fatal to the maintenance
of lower temperature than that out
side the building. The object is to re-
tain a 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,
So that as the purpose of ventilation is
to 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,
as it will purify the air by TAX
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 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 Il receptacle for
the ice, protected in the same way as
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 as 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 to
one corner, where drain pipe is fitted
having-for safety against entrance OF
air-a curved trap made like an S laid
on its side. 1t wall be an extra means
of safety to have two of these, one in
the closet, through the corner of which
the drainage flows, and another out
side at the entrance into the drain
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 upor
the mode in which it is constructed OF
/ she size of it, and on the quantity o
: stuff in it to be cooled The best tenn
7erature is As degrees, for at any lowe
degree something will be damaged
rs by freezing, which .injures tin
, iCXture, and causes a sort OF drainag
If the liquid matter after thawing
Meat is thus damaged consid
, erably, unless it is kept constant
frozen until it is used The temperu
ture mentioned is the best, as show
/ by practical business in this way, 70
a milk and all other domestic supplies
The rule must be to keep a sutticen
o quantity of ice always in the uppe
a part of the closet TO maintain the de
gree of cold desired. A very short ez
: perience will give the needed informa
ton in this respect, The only rule {
= be guided by is the general one, tina
J, one pound OF ice in melting will TAX
up 142 degrees Of heat, and thus coo
!, one pound of anything from ia dc
grees to 81. These figures viii enabl
> you to make a calculation by the rule
I OF proportion. A thermometer in th
i closet is indispensable to maintain a,
