and Sunlight to Procure the Rest
American Exposition.
The Pan-American Exposition viii
prove 10 be Of more genuine benefit to
those Interested in the proper care of
live stock than any previous effort in
this direction. Stable construction is
a question that appeals with great
force TO every farmer who is anxious
to secure good results. The question
of expense is a great barrier to the
proper building Of this necessity. I'm
fortunately some of the early examples
of good stables were built by men Of
large means, regardless OF what the
cost might be. AS result practical
farmers were slow to take the matter
| up, as the idea of properly construct
ed stable became at once associated
with great expense.
One object of Mr.. +. A. Converse,
who has charge of the live stock and
dairy products at the Exposition, in
building model stable at the Exposi-
ton is to counteract this erroneous i'm
preston.
A properly constructed stable is not
necessarily an expensive one. Cleanli-
ness. fresh air and sunlight. with n
modulated temperature, may be OBJ
tanned in building of ordinary cheap
construction If properly arranged.
A light. cheap framework covered
with paper which is protected with
sheathing Of very common boarding
and covered with a good roof makes
very good start. This should stand on
ground that Is we'll drained and ex-
posed to the sunlight. but protected
\ from cold winds The floor should be
of cement and carefully designed to IA
ciIltate cleanliness in every particular.
Double doors. fly screens and dark
blinds should be provided and made to
tit properly
A system of ventilation should be
provided that will ventilate. Anything
will not do. BY excluding the cold and
the light ordinarily we also shut out
the fresh air, without which no an
imal can thrive Many stockmen are
careful about the quality of the food,
though careless about everything else
in connection with the stable. In this
manner they are protecting their stock
in one direction while leaving them ex-
posed In many others.
Stable air is devitalized by passing
through the lungs. II is also being con-
taminated by chemical decomposition
of the excrementum as well as the
fumes arising from the fermentation Of
damp bedding. etc.
TO thoroughly understand now 10
properly ventilate a stable il is neces-
sary TO study the circulation Of air at
changing temperatures. which is gov
erned 10y fixed laws and may be easily
understood. Warm air is lighter than
cold air. Generally speaking, foul air
is heavier than fresh pure air from the
outside even at the same temperature
Starting from this well known princi-
pie, ventilation should be arranged ac-
cordingly. Fresh air should be let in at
the top and the foul air taken out at
thesbottom.
By experimenting we find If we
smoke a cigar in the middle of a room
the smoke goes first to the ceiling,
where it spreads in every direction nm
til it reaches the side walls when it
will descend.
This would Indicate that we should
admit fresh air at or near the center
Of the ceiling and draw the foul air
from the different sides of the room
near the base. There are two systems
IN use ia our best stables. One forces
tbe fresh air In. the other, the King
system, draws the foul air out AS
Mr.. Converse prefers the latter, that
is the system he will demonstrate at
the Exposition.
1t consists of an air stack with a
hood, the opening of which is turned
away from the direction from which the
wind is blowing. TO this main air pipe
are attached feeders from different
parts of the stable. These feeders have
slide openings to admit and carry off
the foul air from near the floor at the
sides Of the stable Fresh air Is ad-
mitted through central opening in the
roof
As the draft that is created 10y the
hooded stack Is sufficient TO draw the
bottom air from the stable, fresh air
must 90 down through the central
opening to take its place. and a change
of air is a certainty. To prevent the
intake from striking the animals too
strong a shield is placed under the
opening which assists in directing the
flow Of fresh air along the ceiling In
this manner it mixes with the warm
