KEEPING WARM.
Some Scientific Facts and Principles
Plainly stated.

Plainly stated.
That sheltering all animals from
.oid weather, from chilling winds
which by their rapid motion carry of
heat more rapidly, is the way to save
food and to save waste of flesh. IL
by stopping this waste of heat from
the surface all the food consumed will
not be wanted TO make heat, 4 portion
Of it can 60 to increasing the flesh,
that is to producing growth, or more
can he used in making milk, eggs,
etc, within the animal.
DySpeptc persons, those having
feeble digestion, or poor appetite,
get less internal heat from food COM
buStion and suffer from cold. Such
persons need a warmer atmosphere,
Or warmer dwellings, and warmer
clothing to retain the heat that is
produced. This applies to all ami
mails.
Close-ftting garments, garters, lac
ing, boots, shoes, neckties, etc. that
prevent free, easy circulation OF the
blood. each and all diminish the
amount of heat produced, and its uni
form distribution. Exercise promotes
more rapid circulation of the blood
and increased heat production.
Rubbing wet horses and other ami
mails dry is very useful, not only TO
save heat, but also to save cold-tak-
ing, For the same reason any damp
gar menus should be replaced with dry
ones as soon as possible, or enough
covering be added to prevent chilli
ness from the evaporation,
Free perspiration (sweatlng) IN hot
weather carries off large amount or
heat, and keeps down the tempera-
ture. If perspiration be checked,
spOnging with water aids in cases of
sun-stroke or depression from heat.
Persons have gone into hot ovens I'M
harmed by encasing themselves in
moistened garments, the evaporation
keeping down the heat from the body.
Green wood, besides It's inconyen-
ience is very Improbable. A large
amount of heat which the dry por.
tions would yield is lost by icing car
ried off in the evaporation of the sap.
So of any wet or damp fuel Of any
kind
As confined air is poor conductor
of heat, all fabrics that are porous,
that is full of little interstices, tubes,
or holes filed with air, are the best
protectors to keep heat from escap-
ing from the surface of the body. A
loosely woven garment or bed cover
lid is warmer than a compact, firmly
woven one, because the air in the
texture Of the former conducts heat
less rapidly than the more solid ones
Loose-htting garments are warmer
than close-titting ones for reasons
above given, and also because the air
space between them and the skin is a
non conductor of heat.
Stone, brick or wooden walls, with
perpendicular air spaces in them, are
warmer than solid walls, because the
air conducts the heat away less than
the solid materials. A sheathing or
tarred paper, or pasteboard or of any
thick paper even, placed midway be-
tween the clap-boarding and the plas-
tering, to form two thin air-Chambers
instead of one. adds greatly to the
warmth Of a house or other building.
Two half-inch boards, set a little apart
TO leave an air space between, makes
far warmer house wall than the
same thickness of wood in inch
boards
A layer Of loose straw put between
the wall and the earth banking up Of
cellar adds much to the warmth on
account Of the air in the meshes Of
the straw. The same is true in COW
ering roots or apples to be left out in
heaps over winter
Double glass windows are several
times warmer than single glass,
because of the non-conducting film of
air between. So Of double doors.
Moving air both carries off heat
faster Of itself and also increases
evaporation, thus largely diminish
ing the temperature very small
crack in a window Under or over, or
by the side of a door or sash, or else
where, produces a draft that requires
much extra fuel to counterfeit the
effects "A merlcan Agrculturist.
