The Philosophy OF Milking.

THE udder is divided into four parts,
entirely distinct from each other, except
as they are held together by membraneous
ligaments. The milk in each is held in
continent tubes, which, like the roots of a
tree, are all contracted into one just above
the teat; the milk entering the funnel
shaped organ by single channel. Just
at the upper end Of the teat the walls of
this channel are contracted, and the con.
traction is surrounded by band of mus
Cular fibres. The will of the cow can
operate on thi, band, contracting or ex-
panding it at pleasure, making it operate
like valve At the junction of each
smaller tube with large one is similar
contraction and band, also under the con-
troll of the will. Ordinarily these bands
are contracted (as in the neck of the blad-
der), so that the milk has to crowd its
way through them to get from the smaller
into the larger tubes.
This is an admirable arrangement for
sustaining the weight of the milk equally
in all parts of the udder, and preventing
it from pressing heavily upon the teats. o
When the udder is full, if the milk is
drawn out of the teats, relieving the pres
sure in them, it requires vigorous effort
of the will of the COW to prevent the
pressure above from crowding the milk
down to nil tho vacancy. If the udder is
only partly filled, she can hold the milk
back more easily; and the less there is
in it the more easily can she maintain
the tension Of the muscular bands neces-
sary to prevent entirely the milk from
flowing through them. When the milker
first takes hold Of the teats and begins to
milk, the excitement causes the COW to
contract the bands so firmly as to hold
back the milk perfectly for time. But
presently this vigorous contraction will
begin to slacken, and the milk will begin
to pour through, and if all is quiet She
will relax the bands fully; when the milk
all settles down upon the teats and is
quickly drawn it can be all MIXED out
to the very last drop.
But this perfect relaxation will onlv
last short time. If the milk is not soon
extracted she will begin to tighten up the
muscular bands again, and the last part
of her mess will be held back and per.
manently retained, when the mixer prob

stops coming. A COW should therefore
be milked quickly as we'll as quietly. II
is natural for her to part with her milk in
few minutes, and milker should come
as near that time as possible If the time
Of milking is much prolonged she will
become impatient and be sure not to

ders and the longer will it last. If any
thing occurs to disturb or excite or attract
their attention, the relaxation will cease

close of the milking some of the best
