No breed appears to have all the requirements for a herd of 

 standard milk producers, and the best resource of the farmer is 

 the selection of animals whose mixed milk will meet the require- 

 ments of the law and whose yield will be large enough to be 

 profitable. To do this the farmer will be much benefited by 

 having his individual cows tested from time to time. 



The Babcock test will give satisfactory results and should be 

 within the reach of every farmer. The Agricultural Experiment 

 Station will gladly help to the extent of its ability ; but will be 

 obliged to charge a small fee sufficient to cover the cost of the 

 work. The amount of this fee will be twenty-five cents per 

 sample for a determination of total solids and ten cents per 

 sample for fat. In preparing samples to be sent to the station, 

 a full day's yield should be represented, since there may be a 

 wide difference in the composition of night and morning yields, 

 owing to the irregularity in milking or other causes. 



The cow should be milked dry, and the milk should be strained 

 by itself ; then at once dip out about one gill into a clean 

 tumbler or jar and cool the sample as quickly as possit)le. At 

 the next milking take another sample in the same way and after 

 it is cooled turn night and morning milk together and mix 

 thoroughly. 



If it is intended to send the average milk of the herd, it is best 

 to strain all the milk into a large tank, and mix thoroughly by 

 stirring. If it is not convenient to do this, strain each cow's 

 milk by itself, dip into another pail as many gills as there are 

 quarts given, and repeat with each cow. Mix this milk thor- 

 oughly and take out a sample. 



Not less than a four ounce vial full should be sent, and the 

 vial should be filled to the cork, to prevent any possibility of 

 churning. 



In all cases, parties sending milk to the Experiment Station 

 for analysis will be required to pay the express charges, and to 

 notify the Director or Chemist by mail that the sample has been 

 shipped. The notification is especially important in order that 

 the sample may receive prompt attention.
