The tail is often measured in judging
the COW and should reach to or below
the hooks and carry a good switch.
This renders it most useful in brush
ing flies, which appears to be it's chief
purpose.
In judging the quality and condition
of the muscular tissue of the body one
should remember to take into consid
Grafton the size, age, and stage of
lactation of the animal. The bone
and muscular tissues in a large COW
are naturally heavier than in a small
one and there is not the apparent re-
finement and spareness of form in the
large breeds that is noted in the
smaller ones. Marked coarseness,
however, in any animal is usually
accompanied by a sluggish DISPOSE
ton which in a dairy cow prevents
her from performing satisfactorily.
Young heifers with first calf usually
carry more flesh than cows of mature
form. All properly fed COWS usually
show a higher condition of flesh de-
velopment toward the close of their
lactation and prior to freshening than
they do when four or five months ad.
vanced in lactation.
The Udder-The udder is the milk
secreting organ and it's proper devet
opment is, therefore, essential. In
many instances cows of large digestive
capacity and of dairy breeding have
failed in production apparently on &C
count of poorly developed udders. The
udder consists Of two large glands
each of which is more or less distinct
ly divided to correspond with each o
the four teats and form the quarters
The duct OF each teat enters a small
cavity termed the milk cistern. Th'
milk cistern of each quarter is NOR
or less surrounded by lobes of glant
tissue held in position and closely tc
gether By connecting tissue. Thes.
lobes may be likened to thick bunche;
of grapes since each lobe has severa
lobules corresponding to the grapes
The IobuIes are made o. small divisions
called alveoli which correspond to thu
seeds of grapes. These alveoli ara
constructed Of small cells surrounded
by a fine network Of blood vessels ana
nerves and it is by these cells that the
milk is secreted.
The best cows have comparatively
large udders with equally developed
quarters extending we'll forward un.
derneath the body and good distance
up behind and between the thighs.
Poor attachment giving a swinging or
pendant type of udder and deficiency
and irregularity in the development OF
| the quarters are criticisms to be of.

plastic texture rather than fatty tissue
or texture that is coarse and hard.
The circuIatory System.-This sys-
| tenn determines the activity of the
| cow with respect to all parts of the
| body. Only when in perfect health
and all parts Of the body are actively
| performing their respective functions
can the dairy cow be expected to yield
] a large flow of milk When the COW
! is sick or by virtue of her poor indi-
viduality is dull and morbid there is
an inactivity of all the glands of the
body resulting in a dry, harsh cond1-
| ton of the skin, a staring coat, and a
| low production of milk. The circula-
| tory system includes the heart, lungs,
| arteries and veins since these organs
| respectively force, purify and carry
| blood to and from all parts of the
| body. When food becomes digested
and assimilated the blood must carry
| it to the parts of the body demanding
| it and in the dairy COW the glands of
| the udder demand a large share of the
nourishment of the blood for the secre-
ton of milk. The size and character
| of the milk veins, more properly
| termed ''mammary veins" and the
milk wells on the underside of the
body are the best indications of how
much blood passes through the udder.
| These veins do not cary milk as some
people believe, but carry large por-
| ton of the blood away from the udder.
| The blood passes into the udder
| through arteries located deep on the
| inner side of the thighs. If one were
standing below mill propelled by a
water wheel and noted the race filled
with water from the mill he would
have reason to believe that the mill
was in operation and performing its
work Likewise when one observes
large, branching mammary veins en-
tering the body through wells OF suffi
cient size to avoid a vein becoming
| gorged he has reason TO believe the
| the udder is performing its work We
