tests will be a fair index of the quality of the milk during the milk- 

 ing period. Thus if the milk tests 3.8, 4.2 and 4.8 per cent fat, the 

 average would be 4.27 per cent for the entire period. 



Ufensils A^eedeii in Sampling : A pint lightning jar for each cow; 

 a small coffee cup or long handled gill dipper for taking the sample ; 

 a box of bichromate of potash or B. and W. corrosive sublimate 

 tablets for preserving the sample* to be procured of any dairy supply 

 house at a cost of $1.00 to $1.25 per box. 



How to Sa^nple: Powder fine with a knife one-half of a tablet and 

 put in each jar. Milk the cow dry and pour the milk as care- 

 fully as possible from one pail to another three times in order to 

 mix it. Do not allow any more frothing (air bubbles) than possible. 

 Dip out a cupful of the milk at once and pour into the jar. Mix 

 the milk with the preservative by a careful rotary motion. Do not 

 shake or turn the jar upside down. Proceed in this manner for four 

 consecutive milkings, (two full days). Be sure to mix the milk by 

 the rotary motion each time a sample is added to the jar and keep 

 the jar tightly covered. The jar should be marked with the name 

 and number of the cow.
