Breeding for MIX.

The property of milk yielding is hered-
itary. 1t would indeed be contrary to
reason if it were otherwise for milk is
structurally portion of the COW, and
even its liquid portions are influenced
by the character of the structure through
which they must pass to appear in the
reservoirs of the gland. We thus find
individual cows of great excellence In
any breed which has been used in the
dairy for generations, as well as other
individuals of poor quality, and we are
enabled to determine which ones are
large mixers by external signs of struc-
ture. The popular appreciation of this
fact of hereditary is evidenced by the
general favorabl&opinion of the Ayrshire
breed as of large \milking capacity and
the diferance of opining as to the milk
ing quality of shokthorns. In the one
case, breed kept And reared for milk,
and milk in large Quantity the recogniz-
ed product; in the other case, breed
kept and reared either for milk princi-
pally or for beef purposes, and hence
opinions modified according to the char
acter of the breeding which is under OBJ
seryation. The average yield of the So
called native COW, although she has been
subject to years of unconscious selection
and oftentimes careful selection in her
breeding cannot be in excess of 800
quarts yearly for the best dairy regions
of America, although individual selec-
ton by good farmers may increase the
average yield of first class herds to 800
quarts annually the highest average re-
suits we can figure for single years being
about thirteen hundred quarts per COW.
The Ayrshire breed has, however been
bred for milk, and as consequences the
yield of average herds can be placed at
about two thousands quarts of superior
herds at 2, 500 quarts, and at 8 900 quarts.
even, per COW per year. As we near
countries where breeding is not carried
on for the purpose of milk we there find
but small yields. The wild COW yields
but sufficient for the use of the calf
among. the table lands of Columbia,
where the cattle are but partially domes-
ticated, it is only by allowing the calf to
run with the mother by day that small
quantity of milk can be obtained at night.
Among the Damaras of South Africa q
first rate animal rarely gives more than
two or three pints daily, and this only in
the presence of her calf. The small cows
of Brittany, on the other hand, have
yielded, as an average for five dairies in-
cluding SO cows. 3.243 quarts in year
