FROM THE PRACTICAL VIEWPOINT 



than required by law, some dealers wait until the 

 proper temperature is attained, and then, by plac- 

 ing the thermometer bulb in the milk, they get a 

 record which indicates an immediate rise of tem- 

 perature to the highest point, and then a uniformly 

 even line. Any record which indicates that the 

 temperature has been raised at once to the maxi- 

 mum point, and then continues with no variation 

 during the entire run, should be looked upon with 

 suspicion. Inspectors with a little experience soon 

 learn to detect false records, by evidences not al- 

 ways easy to explain, and they are able to gain 

 from dealers the admission of irregularities which 

 are at first denied.
