just when and how the milk submitted to a contest is produced. 
At the time of milking he has to answer questions as to all the details 
of the process, so that he has a record of the condition of the cows, 
the feed, the cleanliness of his utensils, etc. Then, when he receives 
his score card and observes, for instance, that he has received a cut 
on flavor, he can go over the various details of the production of that 
milk and perhaps find the method which caused the trouble. When 
the samples are taken at times unknown to the dairyman, the direct 
educational value is lost to a certain degree. The dairymen, unless 
they have kept a complete diary of all methods and operations dur- 
ing the entire month, do not know mitil sometime afterwards when 
the samples were taken and have no means of knowing the conditions 
that prevailed when the milk was drawn. 
On the other hand it has been argued by some that the score on a 
sample of milk submitted by a dair^inan is not a correct indicator 
of the average product handled by that man. For instance, a man 
may ordinarily have a very mediocre supply of milk but by special 
efforts he may produce a very high-scoring sample for competition. 
No claims, however, should be made at the milk exhibits, by those in 
charge that a high-scoring sample indicates that the exhibitor has 
an average supply of the same high quahty. It is thought, more- 
over, that a man who learns the principles of clean milk production 
well enough to produce one sample of high-scoring milk is much more 
likely to put those principles into general practice than a man who 
has not studied the principles at all. Excellent results, however, 
have been obtained in the collected-sample contests. 
SOME EXAMPLES OF PACKING. 
Much ingenuity has been shown in shipping milk to some of the 
shows. One firm in Canada made a large box about 4 feet square, 
the sides, top, and bottom of which were made of thick cork. The 
whole was then covered with a preparation of tar to make it water- 
proof, and the bottles of milk were placed in a rack inside and the box 
filled with ice. The whole was then crated to prevent injury to the 
cork-board box. The cork was intended to serve as an insulation 
and to keep the ice from melting so rapidly. 
In 1911 one Colorado dairy sent to the National Dairy Show milk 
which was shipped in a specially constructed crate made as foUows: 
A galvanized cyhnder, fastened at the bottom in a galvanized-iron 
box, was made for each bottle of milk or cream. The bottles of 
milk or cream were set down in the cyhnders and a tightly fitting 
cover placed over the top of each one. Then the space surrounding 
each cylinder inside the galvanized-iron box was filled with crushed 
ice.
