KEEPING WARM.
Some Scientific Facts and Prin-
cipIes Plainly Stated.

From the American Agricultutist.l
Thatsheltering all animals from cold
weather, from chilling winds which, by
their rapid motion, carry off heat more
rapidly, is the way to save food and to
save waste of flesh. If by stopping
this waste Of heat from the surface, all
the food consumed will not b, wasted
to make heat, a portion of it can go to
increasing the flesh, that is to produc
ing growth, or more can be used in
making milk, eggs, ETC., within the
animal.
Dyspeptic persons, those having
feeble digestion or poor appetite, get
less internal heat from food combus-
ton, and suffer from cold. Such per-
sons need a warmer atmosphere, OF
warmer dwellings, and warmer cloth
ing to retain the heat that is produced.
This applies to all animals.
Close fitting garments, carriers, 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, hut also to save cold-taking
as explained in our last number. Fol
the same reason any damp garments
should be replaced with dry ones as
soon as possible, or enough covering
added to prevent chillness from the
evaporation.
Free psrspiration (sweating) in hot
weather carries off large amount Of
heat, and keeps down the temperature
If perspiration be checked, sponging
with water aids in cases of sunstrokC
or depression from heat. Persons
have gone into hot ovens unframed by
encasing themselves in moistened gar.
ments, the evaporation keeping down
the heat about the body. Green wood
besides its inconvenience, is very I'M
profitable. A large amount of heal
which the dry portions would yield il
lost by being carried off in the evap
Grafton Of the sap. So of any damp OF
wet fuel Of any kind.
AS confined air is a poor conductor
Of heat, all fabrics that are porous
that are full OF little interstices, tube
or holes filled with air. are the bes
protectors to keep heat from escaping
the surface Of the body. a loosel
woven garment or bed cover is warme
than a compact, firmly woven one
because the air in the texture OF tn
former conducts away less rapid
than the more solid ones. Loos
fitting garments are warmer than clos
fitting ones, for reasons above given
and also because the air space betwee
them and the skin is a non. conductO
Of heat.
Stone, brick or wooden walls, Will
perpendicular air spaces in them. ar
warmer than solid walls, because th
air conducts the heat away less tina
the solid materials. A sheathing Q
tarred paper, on pasteboarl, or OF an
| thick paper even, placed midway be
tween the clapboarding and the plas
tering, to form two thin air chamber
instead of one, adds greatly to tn
warmth of a house or other building
Two half inch boards, set a littl
apart to leave an air space between
make far warmer house wall than th
same thickness OF wood in inc
boards.
A layer of loose straw put betwee
the wall and the earth banking up
cellar adds much to the warmth o
account of the air in the meshes {
the straw. The same is true in GOV
ering roots or apples TO be left out /
heaps over winter.
Double glass windows are seYeri
times warmer than single glass, be
cause Of the non. conducting film {
ar between. So of double doors.
