pending on the amount of vibra-
ton.
4. The variation of the speed OF
the bowl causes difference of from
one to thirteen per cent in the test
Of cream, depending on the varia-
ton in speed.
5. The amount o; milk allowed
to flow through the separator bowl
from one-half to full capacity
makes difference of from one to
six per cent, depending upon the
divergence from full capacity Of
the machine.
6. The amount of acid in the
milk causes an irregular variation
in the test of the cream, depending
upon the amount OF acid it con-
tains. Where the acid reaches a
high point, three to four per cent
for instance, and the separator is
used continuously for an hour or
more, it will eventually clog the
same as in the case of cold milk.
The cream will then become thick
er until the separator is entirely
clogged. The extent OF the clog
ging will depend upon the amount
of acid in the milk and The size of
the machine. The higher the
! acidity and the smaller the ma
chine the sooner the separator will
clog.
Referring to the first conclusion
above theexperiments show varia-
ton in the test cream ranging from
l to 10 per cent from milk separat-
ed Immediately after milking and
milk as cold as will separate.
When milk is so cold that the
bowl clogs, the cream outlet also
clogs, which has the same effect on
the density of cream as ii the
cream screw had been set for a
heavier cream. There is no econ
omy in separating cold milk, neith-
er is there satisfaction in operating
the separator when the milk is
cold. 1t is always advisable to
buy separator which will handle
cold milk most advantageously be-
cause there frequently occur on the
farm emergencieslby which cold
milk must be separated. 1t is to
be noted then that the condition
of the milk has much to do with
varying test and the condition is a
thing which the farmer cannot be
expected to note twice a day be-
cause to do SO is impractical, but
he must expect variation in his
cream test from this source.
1t is our observation that the a
mount of flush water used in gen.
eral practice has greater effect on
the variation in test of cream than
reported in the bulletin. In the
experiment from which the con-
clusion was drawn only sufficient
quantity of water was used to drive
the cream from the bowl, which a.
mount would not exceed a quantity
as run from the separator without
flush water of Is per cent. The
following morning was frosty and
cold. The milk separated was
equal to the nights milking as
closely as could be determined by
measuring in ten gallon cans. The
cream taken without flush water,
was Is pounds as at night. In
flushing the bowl the farmer this
time used no. water from the tea
kettle and not more than three
quarts. The water increased the
weight of cream three pounds, and
reduced the original test of cream
slightly less than 5 per cent. So
here was a variation ranging from
5 to Is per cent on two separations
all on account of careless use OF
flush water. This happens on
every farm every day where
separator is used. And the same
variation between milkings exist
