94 THIRTIETH ANNUAL REPORT OF THE 



(c.) Sampling - at the dairy. Follow directions under II. 



Either of these three methods of checking- creamery testing 

 is open to objection. In (a) the sample or testing may be in- 

 correctly managed at the creamery, the sample being under 

 control of one of the interested parties, the creamery man. In 

 (b) the sample may be improperly handled by the other in- 

 terested party, the patron under whose control it is located. 

 Method (c) resembles (b) in this respect, and, moreover, results 

 may be vitiated because of error or insufficient care in samp- 

 ling. 



The experiment station strongly urges dairymen as far as 

 possible to make use of the Babcock test at their own homes. 

 It is of more value as used between cow and cow than for set- 

 tling money matters between man and man. 



To such residents of the state as do not consider it advisable 

 to make their own tests, or to have neighbors make them for 

 them, the experiment station offers its services to a limited 

 extent. It cannot do regular and wholesale testing for any 

 individual or company, but will handle small numbers of 

 samples without charge. It makes but few requirements, a^ 

 follows: 



1 Samples should be carefully taken in accordance with 

 these instructions. 



2. Wide mouthed jars should be used. 



3. Jars should be filled absolutely full to prevent churning 

 in transit. 



4. Express charges should be prepaid. In case jars are de- 

 sired back again, the express agent should be asked to affix a 

 "free return empty" label on the package and it will be re- 

 turned without cost. 



5. The shipper's name should be placed upon the package 

 for purposes of identification.
