All the glassware must be perfectly
clean. Wash It In a strong solution of
soda and rinse it well afterward.
Have a representative sample of the
milk or cream to be tested. It must be
from the entire milk, well mixed. Sam
ples of cream, skimmilk, buttermilk
ami wliey must be taken from the bulk
after being well stirred from the bot
tom to the top. At the time o f making
the test the sample should be poured
from one vessel to another, so as to
obtain a thorough and even mixture,
it should be at a temperature o f be
tween 60 and 70 degrees.
A 17.0 cubic centimeter pipette
Is used to take the measure o f milk re
quired. Insert the small end in the
milk and the other end In the mouth,
draw up the air and the milk rises In
the tube. When the pipette Is filled
with milk, quickly place the Index fin
ger o f the right hand over the top of
the pipette. Hold the pipette on a level
with the eye and slowly allow a little
air to get In by slightly easing the
pressure o f the finger. The milk will
run out In proportion to the air ad
mitted. When the milk exactly reach
es the line Indicating the proper
amount for a test quickly press down
the finger.

T e stin g Cream .
Cream lest bottles are graduated to
read as high as 30. 40 or 50 per cent
fat and are made with a large neck.
i
Use nn eighteen cubic centimeter pi
pette for measuring the cream. Rinse
the pipette with a little water to get
out the full complement of creuin. Aft
er mixing the cream and acid add the
hot water before whirling and whirl
for five minutes. Place the bottles In
hot water before reading.
Each division o f the scale reads one-
half or 1 per cent, according to the
marking.
The proper amount of cream or milk,
etc., for a test is eighteen grama.
Owing to the small percentage o f fat
in skimmilk, buttermilk and whey, to
get accurate tests double necked test
j bottles should be used.
The amount Is taken in a 17.6 cubic
centimeter pipette and tested In the
usual way. The milk has to be deliv
ered slowly Into the larger neck or It
bubbles out. The scale on the neck
reads to "ne-hundredth o f 1 per cent.
| One large division reads flve-buu-
| dredths or .05 per cent fat.
It is not always convenient nor Is It
necessary to test daily when a yearly
record Is being kept o f a herd or when
milk or cream Is delivered at a factory.
We will suppose a herd test Is to be
kept. There should be a pint bottle
with a long tight fitting cork for each
cow. The cow ’s name or number
should be plainly written ou a label
which Is gummed well on the bottle,
then given two coats of shellac so as
not to have the label wash off.
The bottles should be placed on a
convenient shelf In the milk room sep
arated from the stable. Hanging near
should be u pair of spring scales set to
record the net weight of milk. The
milk pails should be all the same
weight.
On a board by the shelf should be
tacked a record sheet to mark the
pounds o f milk at each milking.
To keep the milk from curdling In
the test bottles a preservative is nec
essary. The one commonly used Is
seven parts bichromate of potash to
one part o f corrosive sublimate, but
three parts o f the former to one of the
latter give better results. This Is poi
sonous, but ns It turns the milk a de
cided yellow no one is apt to drink It.
Rut about as much of this powder ns
can be lifted on a ten cent piece Into
each bottle. This amount o f preserva
tive will keep the sample good from
two to four weeks, according to the
heat of the weather. If very warm
use more. Avoid too much, ns it spoils
the test, giving burnt readings. Pre
servative tablets may be procured and
are more convenient.
The sample is taken night and morn
ing by means o f a long handled one
