In the preservation of eggs with
water glass a very considerable saw
Ing may be effected by exercising sui
flcient care in the protection Of the
preserving solution from the air to
permit of its reuse for several sue
cessive seasons. The largest item in
the initial cost Of preserving eggs by
the water glass methods aside from
the cost Of the eggs themselves lies
In the container rather than in the
solution; but the Former is used over
and over again while the latter, ac-
cordings'to the general practice, IL re-,
newed for each succeeding lot OF eggs.
IN, mostrinstances the discarding Of
the old solution has been made neces-
sary by the deposition of practically
all Of the sodium siiicate which was
originally In, solution as water glass.
This IS caused by the chemical action
OF the carbon dioxide Of the air. and

sodium carbonate or soda. The &C

the appearance Of decided milkiness
in sths solution and, as It continues, 8
thick heavy sediment forms which
settles around 1.-THE eggs, making 1t a
diAcult matter to remove them with!
eut. some Areakage. ,
The easiest method Of preventing
this precipitation is to prevent the
free circulation Of the, air. This may
be accomplished By using containers
with tightly fitting covers or BY seal.

jars with parafiin. F"' ,s~ -<,..-''..
The latter scheme Is carried out by
winding q strip Of paper around the
top qfsthe jar with the upper edge ex-
Tending little above the edge Of the

With icord or held by means Of rub.

poured, into the groove between the
paper and the cover edge which on
hafdening win enectually seal the Jar.
This paraf1n may, Of course, be re-
used. ~... ~ %s'~F ,~>@#@.. ..
In this way a solution will keep
through the year without showing any
signs of precipitation and may be
used the following year IN the same
way. $50 ~,, III 'a .--.. r
When q container Of eggs has been
emptied 1t should be re-sealed or the
solution should be poured into bottles
and securely corked.
From the standpoint Of economy in
the preservation of the liquor, small
containers suitable for week or ten
days egg supply are more desirable
than a large key containing all of the
eggs for an entire season.
The small containers may be opened
one at a time as needed; while in
the latter case the key must be sub.
jected to almost continual stirring and
the precipitation of the silicate will
be much more rapid and difficult to
guard against.
II sealing of the containers is not
practical, it will be found that the
precipitation is slower in q we'll venti-
lated room than in cellar. which In
many instances contains larger per.
centage Of carbon dioxide than Is
normally present in the atmosphere.
coops will much more than pay the
express on half a dozen standard
coops. Homemade coops are usually
SO much heavier that the additional
express charges are considerable.
The standard coop should never
contain more than from 100 to 125
pounds Of mature fowls, or from rs
to 100 pounds Of young fowls. If this
rule is observed, the loss is reduced
to q minimum. Overcrowding often
results in death, or abnormal shrink.
age or both. Coops that sEe too low,
or closed on the sides, should not be
used because Of danger Of suhfocation.
Coops for any kind Of poultry should
be SO made that the birds can stand
up In them. iasg 1#2l'@ f51iAf
