other conditions the number may be increased. The palmitic is
present in largest amounts, and assertion has been made that
the coloring matter of the fat is most intimately associated with
it. The yellow pigment of milk is called carotin, which is simi-
lar to the coloring matter found in carrots. The fats differ
chiefly in their hardness or melting point, and in their ability to
produce different flavors in butter.
 HOW FEEDS AFFECT FAT
 As previously stated, the feeds may and often do change the
color of milk and cream. Certain feeds also have a considerable
influence on the melting point of the butterfat. For example,
cottonseed meal produces a hard fat, while soybean meal pro-
duces a soft fat.
 Buttermakers often experience difficulty in working the but-
ter, especially when molding it into prints. Sometimes the but-
ter may be so soft that it is almost impossible to make it into
prints. At other times it may be firm, and show good grain and
texture. This condition is influenced very largely by the feeds
used. The methods used in ripening and churning the product
must also be taken into consideration.

 THE MILKER AS A FACTOR IN PRODUCTION
 Good cows and good feed are two of the important factors
in profitable dairying, yet a great deal depends on the milker.
Good cows plus good feed plus a poor milker equals failure. To
produce the maximum flow of milk the cow must be milked reg-
ularly at the same hour each morning and night. In addition to
regularity it is important that she be milked dry each time. The
inclination of the cow is to produce no more milk than is needed
by the calf, and cows that have always nursed calves rarely if
ever become good milk producers.
 Kindness is perhaps one of the biggest words in dairying. This
applies particularly to the milker. The qualifications of a good
milker are, in short, a liking for the work and a knowledge of
the machines-the cows-he is handling. A man who likes
dairy work and understands the mechanism of the cow is almost
sure to make a good milker. A man with this knowledge knows
that it is not profitable to chase a cow an hour or two each day
with a dog, or to curry her twice a day with a milk stool.
Such treatment is not conducive to the maximum flow of milk
