The fireless cooker can be used to
keep food cold as we'll as hot, because
heat cannot pass in to warm the con-
tents any more than it can pass out
and cool them. In this respect 1t
works very much like refrigerator.
In fact, both the cooking box and the
ice box are constructed on the same
principle-supplying constant-tem-
perature chamber with non-conducting
walls. Well-constructed ice boxes are
made with some insulating material or
dead air space between the inner and
outer walls, and the covers and doors
close in such way as to prevent heat
passing in or out. Of course, the more
often the doors are opened, the more
heat passes in and the more quickly
the ice melts and the temperature
rises. Fortunately this is less serious
than the loss Of heat when fireless
cooker is opened.
When the cooker is used to keep
food cool it must be chilled to the de-
sired temperature before it is put in.
The more nearly heat-proof the walls
the longer the material keeps its orig
NAL temperature. Ice cream put in a
well-made fireless cooker ought to re-
main firm as long as if it we're packed
in salt and ice in an ordinary freezer.
Many cooks prefer to pack such half
frozen desserts as mousse or parfait in
to the nextneighbor who comes in. 1t
will give you an enviable feeling to
be able to say, 81 made that myself.
1t cost very little and does good work"

How to Make the Cooker.
Scour frkin, let it dry thoroughly,
and put in casters.
Line with several thicknesses of
newspaper tackled to sides.
Put in solid layer of excelsior about
inches thick. This should be at least
inches thick, but might well be more
If the frkin is deep enough to permit.
Fit asbestos around pail and wire or
tie it firmly.
Cut circle Of asbestos little larger
than the size of the pail and place on
top of the Pinch layer of excelsior.
Set pail on top of this and weight
before starting to pack around it in
order to avoid having the pail move
out of place.
Put in small amount of excelsior
around pail, distributing it evenly.
Pound down with handle Of hammer
or something else heavy.
Continue packing excelsior. and
pounding down until it is about one
half inch from rim of bucket The
more solidly the excelsior is packed,
the more efficient will be the fireless
cooker.
Cut cardboard collar to fit between
inside well Cor pair and outside the
wood container and set in place.
Cover this with mixture of plaster
paris-1 part plaster paris to 2 parts
Of water. In putting on mixture avoid
having layer come up above rim of
pail. If not thin enough to put on
smoothly, rub down with fingers or.
with knife blade.
Paint after plaster of paris has dried
thoroughly.
Fill pillow full enough to make it fit,
snugly between we'll top and lid.
Fasten lid with hinges if box is
dsed.

which can be successfully cooked in it
can be procured from your state agri-'
cultural college or your home demon
stration agent. Have your cooker
ready for the recipes they will send
you on request.
