The whole structure of the udder is a
complicated and delicate affair. The
arteries going to the udder are both
large and numerous, and the branches
Of each vessel freely anastomose TO
gether, SOsthat no Interruptions to the
regularity of the supply of blood to
every part of the gland may take place.
HE several vessels which come soff
hom these arteries penetrate into the
Substance OF the mamma, within
which they freely ramify by numerous
divisions and subdivisions. Ulti-
mately, by further splitting up and
consequent diminution Of their caliber,
they form vessels 50 minute as to be
undesirable to the naked eye, and
which have been designated capilla-
ries. They are distributed to the folli-
Giles or coecal extremities of the lac
tiferous ducts, upon which they form
minute rete of vessels. and furnish
blood, both in sufficient quantity
and also in q condition fitted for the
secretion of milk. From the coecal
extremities the milk. as it is formed,
finds its way along the minute
excretory ducts to which they are at
tached into large tubes, and thence
into yarious-sized cavities, which are
termed reservoirs. The arrangement.
Of this portion of the gland may be
compared to punches of currants as
connected with OF growing upon their
fruit stocks. The fruit would here rep
resent the milk-secreting follicles, and
the stocks the tubes by which it is con-
veyed away.
1t will be seen from the above that
structure SO complicated and deli
cate is liable to become deranged in
some of its parts by improper usage,
and that it cannot well maintain its
integrity when milk is allowed to ac
cumulate and remain to decompose
and become rotten, as it often does
when there has been neglect in proper
ly "drying off the animal. When
cows begin to fail in their milk, the
supply of blood to the glands becomes
less, and when milk is left in the ud-
der a portion of it will be absorbed in
the system, Nature taking this way to
rid the glands of a substance which re-
quires to be removed. But when the
milk coagulates, the caseinous portions
become hard and remain. Thus.
when the COW again comes in milk,
we find this foreign substance acting
as an irritant, inducing. not unfre-
quently, violent inflammation. and we
have /" swelled bag garget, or some
disease of the udder which causes
trouble. Often particles of coagulated
milk fill up the milk duct at the base
of the teat or lower down, causing
stoppage of milk through the duct,
and hence spelling the teat for fur
Their use. OF late years large num-
Der Of cows throughout the dairy dis
tricts are found which have lost the
use of one or more teats, and they are
generally among the best cows Of the
herd. The cause is largely owing to
neglect in properly drying off,
Cows cannot be dried of their milk
at once, and some cows continue to Sc
crete milk in small quantities for
long time. But in all cases where the
animal has ceased to give milk, or is
what is termed "dry," she should have
her udder examined from time to time
and the teats tried to see if any milk
can be drawn. At first the trial should
be made at intervals of two or three
days, and if there is particle of milk
in the bag it should be all thoroughly
drawn. Then the trial may be made
at longer intervals. When cows are
supposed to be completely dry, the rule
should be to 60 through the herd ev-
cry week, making trial of the teats to
see if any milk can be drawn. And
this work cannot safely be intrusted to
"hired help" but must be performed
under the "eye of master Many
persons are not aware Of the impor-
lance of drying cows, and hired help
often think it a piece of folly to try
to draw milk from a dry COW. We
| have had such men, and they were
good, honest men, too, and they would
| insist that certain cows were perfect
| ly dry, but yet, when put TO the test
under our rule Of trying the teats
once week during winter, we have
| found, in numerous instances, that
small quantities of thick milk, or a
watery fluid could be drawn from the
/ udGer.
We have lost the use of valuable
cows by intrusting this work to per-
sons in our employ, and there is scarce
ly dairyman in New Y ork who can
not trace trouble in his herd to either
| his own neglect or that of others. In
deed. so large is the loss every year
from improperly drying cows that
there is scarcely subject connected
with dairy management of more vital
