Ventilation of Stables.

VentiiatIon OF StapieS.
H. M. Culbertson, of Wisconsin, in
an address said:
One of the first indications of an inn
properly ventilated room is the accu'
mutation of frost on the walls in cold
weather. This is caused by the abun-
dance of moisture being carried in the
warm air and returning to water when
striking a cold surface. This indicates
too much moisture for good health. In
occupying a room in which we feel
that breathing is carried on with un-
usual difficulty, a shortness of breath,
where we soon become in a sweated
condition, illustrates a lack of sufh-
c1ent oxygen in the air. Cobwebs
soon become laden with an accumula-
ton, germs of disease from animal
refuse and other sources are likely to
ind lodging places here, and be con-
veyed to the weakly tissues and mem
branes of animals. One disease so
contracted and which has become
more or less common is tuberculosis
There is no fixed rule for adoption
in ventilation of buildings, but a prin-
ciple which can be varied to suit most
any barn structure. The first to be
provided is an outgo fiue for remov-
ing moisture, impure air. and the
coldeSt air in the room, which is near
est the floor. Four twelve inch boards
with their edges planed are joined to-
gether SO as to form a long box.
This to be placed at a convenient loca-
ton in the Stable, and spliced to make
it of suitable length to reach higher
than the highest point of the roof.
When placed about eight inches from
the floor, made as tight in the joints
as possible to insure gooa draft, 1t
will make very satisfactory ventilat-
ing flue.
When placed to draw near the floor
the coolest air in the room will be re-
moved and the vacuum thus formed
will be filed with air from a higher
elevation and warmer, giving more
uniformity of temperature in the
stable. To supply a draft for this
outgo f1ue and to secure pure air in
she room, be governed by the follow
ing: If the building is a wooden
structure with inside and outside
boarding, make an opening in the in
side boarding just below the over
head ceiling four by twelve inches,
and another of the same size below it,
but on the outside, about two feet
above the ground.
The pressure of the outside winds
will cause an inward and upward
movement of air through this hollow
wall into and at the top of the room,
where the inside air is the warmest,
and then, because of an outward cur
rent through the inside ventilating
fue the intake of pure air will go to
replace the outgo, changing the air
in all portions of the room, provid-
ing these intake ducts for pure air
are located about every fifteen feet
apart on all sides of the room, and an
outgo ventilating flue for every five or
six animals.
One additional feature will be peces-
sary, which is, a large opening, to be
made the outgo ventilating f1ue at
the top of the room, with a damper
or slide to close the opening, so that
when the room becomes over heated
or carries too much moisture, this may
be opened to remove these conditions,
and every intake duct must be pro-
vided with slide to close if the room
becomes too cold. A closely built
stable must have so many square
inches of intakes as there is of outgo
surface. The same hollow walls can
be built when constructing stone wall
stables, and to secure the same de-
sired conditions where stone walls are
already built. If there is an opening
through the wall at the ground, as
some have for cats to pass in and out,
construct a wooden box of suitable
size for an intake duct with an elbow
at one end, and on the inside of the
stable insert the elbow into the open
ing in the wall, raising the other end
to the top of the room and plaster
closely, so there will be no opening at
the bottom, only through the inserted
duct.
