cows within the first seven days after calving, or from cows 
otherwise in abnormal condition. Such milk is often abnormal 
in its chemical properties, and, when subjected to high tempera- 
tures, undergoes changes that make its manufacture into a mar- 
ketable condensed milk difficult. 
Control of Quality—Every well managed milk condensing 
factory plays the part of an educator in the production of sani- 
tary milk. The condensery usually issues a set of rules, setting 
forth specifically the conditions under which the milk coming 
to the factory shall, or shall not be produced. Copies of these 
rules, which are generally a part of the contract, are placed in 
the hands of all patrons. The condensery employs one or more 
dairy inspectors whose business it is to see that the rules are 
rigidly enforced. These rules cover, in general, the following 
principal points: 
1. Cows.—The milk must come from healthy cows. Milk 
from cows that are diseased, or that have a diseased udder, or 
that are otherwise in poor physical condition, will be rejected. 
2. Feed and \Water.—Do not feed weeds, roots, or other feed 
stuffs possessing strong and obnoxious odors, such as onions, 
garlic, turnips, cabbage, wet distillery slops, decayed, musty or 
sour silage, or other fermented feed. 
3. Lactation Period.—Reject all milk from cows less than 
thirty days before, and of the first seven davs after calving. 
4. Milkers and Milking —Milk with clean, dry hands into 
clean utensils and remove the milk to the milk room immediately 
after drawn. 
5. Straining.—Strain the milk in the milk room through a 
fine wire mesh strainer (80 to 100 meshes to the inch). Do not 
use cloth strainers. 
6. Cooling.—Cool the milk to 60 degrees F. or below and 
keep it at that temperature until it reaches the factory. Do not 
mix the warm morning’s milk with the cold night’s milk; cool 
the morning’s milk before mixing, or send it to the factory in 
separate cans. 
7. Care of Utensils:—Rinse with cold water, wash with 
warm water and washing powder, and rinse with boiling water
