24 TESTING AND HANDLING OF MILK AND CREAM 
1. An Upright Tubular Boiler with steam fittings and connec¬ 
tions is the best and most efficient means of securing plenty of hot 
water so necessary in every station. It also will provide steam for 
running the Babcock tester. 
2. A wash sink made of half rounded galvanized steel large 
enough to hold a ten gallon milk can is considered best. The two 
compartment sink has the advantage of keeping wash water and rinse

water at hand at the same time. There should be a good drain con¬ 
nected with the sink; if a drainage system is not at hand to drain to, a 
fifty-foot tile drain four feet under ground leading to a stream, gully, 
or ditch, will serve the purpose. 
3. The Babcock tester should set level and on a solid foundation 
in order that it may run smoothly. If it shakes it will cause a remixing 
of the fat, and consequently an inaccurate reading. 
A twelve-bottle tester is large enough for the average station. 
4. The law requires that milk cans or receptacles be inverted in 
pure air and cover removed. This is a very wise and necessary precau¬ 
tion, to keep the cans in a good, sweet condition, and can best be ac¬ 
complished by the use of can racks made along the side of the wall. 
Substantial uprights and one by four or one by two crosspieces nailed 
with eight nails makes a very desirable and cheap rack. 
The boards should be painted so as to be more easily kept clean. 
Nails in the racks directly above the position of each can will serve 
as hangers for the lids. 
5. Weigh scales should be accurate and sensitive to a quarter of a 
pound. 
6. The most common and most accurate samplers, when used in 
combination with one another, are the stirring rod having the curved 
disk on the end, and the McKay sampler. 
7. Cream test scales should be level when in use, and sensitive to 
a drop of cream. The Torsion balance is the most satisfactory form. 
It may be obtained with a capacity of from one to twelve bottles. 
Where a large amount of testing is done, the large scales are best as 
the work is more rapid. However, an error made in weighing one bot-
