! (By J. n. F'RANDSON.)
! Through mistaken ideas OF some
writer's. many of our farmers have
developed the idea that 70 keep cow
healthy and comfortable and to pro
duce sanitary milk it is absolutely
necessary to have expensive Dai!ls.
AS a matter Of fact many Of the DAIRY
barns where sanitation is the primary
| object are quite inexpensive.
| On the other hand, II 1t is TO De
conveniently arranged to embody the
most accepted sanitary features, II IS
very essential that some attention pe
given to the plan and specifications
| of the barn that is to house the dairy
| herd to the best advantage. Every
detail Of new barn should be care
fully worked out before actual con-
struction takes place.
The illustration here shown Will, 1t
is hoped, give the builder some new
ideas as to how the barn can be made
more sanitary.
In building dairy barn. or any
other kind of q barn for that matter,
the plans must be worked out to suit
different conditions and locations.
Hardly any two sites would permit
exactly the same plan being used.
If wholesome and sanitary milk is
Ito be produced the farmer should
realize that the cows must be kept
out of the mud as much as possible
Conditions in and around the barn can,
in many cases, be greatly improved by
draining and grading. Draining is not
| of itself sufficient as the tramping Of
1.-THE cattle soon puddles the surface
thus practically preventing the water
| from reaching the tiles below.
The barnyard should have good
slope such as will insure good surface
drainage and should have a good top
layer of gravel or cinders. In
many places this may involve great
deal Of work but even if the grading
cannot all be done in one year ar
rangements should be made by which
| at least part OF it is done every year.
| Too much stress cannot be laid on
| the fact that we have no better disin-
| fectant than good, old fashioned sun
| light. For this reason in planning
our barns much more attention should
be paid to the question OF securing
sufficient light. It Is said by authori-
ties on the subject that four square
feet Of window light should be allowed
for each cow in the barn. Long Win
dows reaching Well TO the ceiling have
been found the most satisfactory for
! the reason that the light coming
| Through them can reach all parts OF
1.-THE barn better than II the short VIM
dows are used. 1t is also Of Importance
to remember that there is no better
way of preventing the spread OF tnber-
culosis in our herds. ahan by admit
ting plenty Of sunlight and fresh air
into the barn
| The hei0ht to ceiling differs som e.
what according to different ideas Of
the builder. but the height should be
isutficient to give ample air space in
the structure.
The important feature of q good
lsystem Of ventilation are that it pro-
air, that the fresh air is admitted near
Ithe ceiling and that the impure air
is taken out near the floor. The fresh
cold air should be admitted near the
ceiling SO that it may. by contact with
the warm air, be tempered before
reaching the cows By forcing the
impure air out near the floor, less heat
| is lost and as is claimed by most au-
thorNies the major part of the impure
air is found near the floor where the
COWS are constantly depositing many
of the impurities given off in breath
ing A damp stable favors the breed
ing of disease germs A good system
of ventilation will carry away all extra
moisture. No system of ventilati on
can be successful in barn where the
